  The present invention relates to a method for using a metal catalyst destructive recovery apparatus for recovering powder containing a metal catalyst from a support comprising a carrier carrying a metal catalyst or a catalytic converter in which the carrier is housed in a metal cylinder.

Conventionally, a catalytic converter is interposed in the middle of a muffler for the purpose of purifying exhaust gas from an internal combustion engine such as an automobile.
The catalytic converter has a structure in which a metal carrier carrying a metal catalyst is joined to a metal cylinder, and a platinum catalyst which is a noble metal is usually used as the metal catalyst. Is expensive and rare, so it is desirable to collect and recycle.
Then, the technique which collect | recovers a metal catalyst from to-be-processed objects, such as the said metal support | carrier or a catalytic converter, is known (refer patent document 1).
Japanese Patent Laid-Open No. 6-205993

  However, in the conventional invention, the pulverized material pulverized and recovered by the impact pulverizer is not separated because the catalyst converter cylinder, metal carrier, and metal catalyst are mixed and separated. A radial blower or cyclone separator is placed downstream of the pulverizer to separate the pulverized product containing a metal catalyst into a pulverized product that does not contain a metal catalyst such as a metal carrier or cylinder, resulting in a larger apparatus. In addition, there is a problem that it takes a lot of cost and labor.

  The present invention has been made paying attention to the above-mentioned problems. The object of the present invention is to impact-break a target object comprising a carrier carrying a metal catalyst or a catalytic converter in which the carrier is housed in a metal cylinder. Another object of the present invention is to provide a method for using a metal catalyst destructive recovery device that can efficiently recover a powder containing a metal catalyst by separating the powder containing the metal catalyst from the object to be treated.

  According to the first aspect of the present invention, there is provided a container into which a carrier carrying a metal catalyst or a catalytic converter comprising a catalytic converter in which the carrier is housed in a metal cylinder, and a container that rotates in the container, An impact wing for separating the powder containing the metal catalyst from the object to be treated, and a floating means for floating the powder higher upward in the container; and the container A method of using a metal catalyst destructive collection device equipped with a dust collector that sucks and collects powder floating inside from a suction port, wherein the suction force of the dust collector is used to generate powder floating in the container. It controls according to it.

According to the first aspect of the present invention, the impact wing is impact-destructed to such a size that the object to be treated falls by its own weight, and the powder containing the metal catalyst is separated from the object to be treated.
Then, the powder separated by the floating means floats higher in the container, and the floating powder is sucked and collected by the dust collector from the suction port.
Therefore, in order to collect the powder containing the metal catalyst that has floated higher in the container by the floating means, the fragments of the catalytic converter and the metal carrier are not mixed in the pulverized material collected as in the prior art. Therefore, it is possible to recover the powder containing the metal catalyst at a high recovery rate without requiring cost and labor with a small-scale facility.

  Furthermore, in order to control the suction force of the dust collector according to the generation state of the powder floating in the container, in a situation where there is little powder floating in the container as in the initial stage of impact destruction of the object to be processed. By lowering the suction power of the dust collector, the cost of power consumption can be kept low, and in the situation where the workpiece is gradually impacted and the powder gradually increases, the suction power of the dust collector is gradually increased. The powder can be recovered efficiently in a short time.

  As a result, the rotating roller 1z of the motor 1y rotates and the rotational force is transmitted to the rotating rotor 1u via the belt 1x. As a result, the rotating rotor 1i (impact blade 1n) rotates in the rotational direction C at a predetermined rotational speed. It is supposed to be.

  The dust collector 2 is for sucking a powder 30 floating in a container 1a of a destructor / separator 1 to be described later through a suction duct 2a, and includes a filter 2b and a storage container 2c.

  The suction force of the dust collector 2 is controlled according to the state of generation of the powder 30 that floats in the container 1a.

Specifically, the dust collector 2 has a time-dependent relationship between the rotational speed of the suction motor provided therein, in other words, the suction force of the dust collector 2 in conjunction with the elapsed time from the start of the operation of the destructor / separator 1. It is controlled to gradually increase with a certain amount of increase.
Note that the fixed amount of change and the suction force are appropriately set according to the type and amount of the object 6 to be processed to be introduced into the container 1a, but in this embodiment, the dust collector 2 is operated when the destructive separator 1 is started. Then, the suction force is gradually increased by a certain amount of increase, and finally, at the entrance of the dust collector 2, the suction force is controlled to be a value within a range of, for example, 13 to 15 m ³ / min.

  The conveyor 3 is for conveying an object to be processed 6 which has been subjected to impact destruction by a destruction separator 1 described later to a sieving machine 4.

  As shown in FIG. 7 (a), the sieve 4 is for vibrating the workpiece 6 conveyed by the conveyor 3 to recover the powder 30 remaining inside the workpiece 6. The main structure is a base 4a, a container 4c fixed to the base 4a so as to be rotatable in the direction of arrow R about a pivot 4b, and a storage container 4r.

  The drive device 4f moves the tongue 4d up and down by moving the advancement member 4e up and down using a motor or solenoid (not shown). As a result, the container 4c is given a shocking motion in the direction of arrow R. Thus, the object to be processed in the container 4c, which will be described later, is swung (see FIG. 7B).

  Two chambers 4i and 4j are formed in the container 4c by upper and lower filters 4g and 4h, and a gap between the filters 4g is formed wider than the filter 4h.

Hereinafter, the operation and effect of the method of using the metal catalyst destructive recovery apparatus of Example 1 will be described.
When using the metal catalyst destruction recovery apparatus according to the first embodiment, first, a predetermined amount, for example, 10 kg of the object to be treated 6 consisting of the metal carrier 7a or the catalytic converter 7b is transferred from the inlet 1b of the destruction separator 1 to the container. Put it in 1a and close the lid 1c.
The metal carrier 7a is a general metal carrier on which a platinum-based catalyst is supported by wrapping a large or small wave metal foil material in multiple layers.

Next, the destruction separator 1 and the dust collector 2 are operated.
At this time, in the breaker / separator 1, the rotating roller 1z of the motor 1y rotates and the rotational force is transmitted to the rotating rotor 1u via the belt 1x. As a result, the rotating rotor 1i rotates at a predetermined rotation speed, for example, about 1500 rpm. To do.

  Further, air of a predetermined pressure is supplied from the air tube 1v, and this air branches in two directions above the air flow passage 1r via the adapter 1w and the air flow passage 1r, and further passes through the communication groove 1s and the communication pipe 1t. The air flow A is jetted from the bottom of the impact feather 1n toward the inner wall 1d of the container 1a, and as a result, the air flow A is directed upward in the container 1a (see FIG. 6).

Then, the impact blade 1n of the rotary rotor 1i collides with the inner wall 1d while scattering the object 6 to be processed, and as a result, the powder 30 is separated from the object 6 and floats in the container 1a. .
At this time, the reflector 1p of the impact wing 1n and the reflector 1h of the inner wall 1d collide with the object to be processed 6 to efficiently destroy the object to be processed 6 and float the powder 30 further upward. Acts as a means.

Further, consideration is given to the object 6 not to be sandwiched between the impact feather 1n and the inner wall 1d by the inclined surface 1o of the impact feather 1n.
Further, since the container 1a is installed in an inclined state, the object to be treated 6 moves downward according to gravity and is efficiently destroyed while being stirred by the impact feather 1n and the reflectors 1h and 1p. As a result, the powder 30 It acts as a floating means that guides upward.

The air flow A acts as a floating means for floating the powder 30 upward in the container 1a, and as a result, floating the powder 30 further upward in the container 1a.
On the other hand, the dust collector 2 sucks the powder 30 from the first suction port 1e through the intake duct 2a and then stores it in the storage container 2c through the filter 2b.

  Here, the state of generation of the powder 30 floating in the container 1a will be described. In the initial stage from the start of the operation of the break separator 1 to the predetermined elapsed time, the object 6 is not damaged by impact so much. The powder 30 gradually increases as the amount of the powder 30 is small and then the workpiece 6 is gradually subjected to impact fracture.

  Therefore, even if the suction force of the dust collector 2 is set to a predetermined value in the initial stage, the amount of the powder 30 that can be collected is small, and there is a problem that power consumption by the dust collector 2 is wasted.

  However, in the method of using the metal catalyst destructive recovery apparatus of this embodiment, as described above, the suction force of the dust collector 2 is gradually kept constant by interlocking with the elapsed time from the start of the operation of the destructor / separator 1. Since the amount of increase is increased, the powder 30 can be efficiently collected in a short time according to the state of generation of the powder 30 floating in the container 1a, and the power consumption cost of the dust collector 2 can be kept low.

  Furthermore, as described above, the filter member 20 is provided in the first suction port 1e, and the powder 30 is sucked from the three directions of the suction portions 24 to 26. For example, even when a peeling piece such as a cylinder of a catalytic converter is sucked and stuck to any one of the suction portions 24 to 26, the powder 30 can be sucked.

  Next, after the predetermined time has elapsed, when the rotation speed of the impact blade 1n is reduced to about 300 rpm, all the objects 6 subjected to the impact destruction move to the bottom in the container 1a, and the object 6 and the powder Separation of the body 30 is promoted, and as a result, the powder 30 floats higher in the container 1a and is efficiently recovered by the dust collector 2.

Next, after a certain period of time has elapsed since the rotation of the impact wing 1n is decelerated, the dust collector 2 and the destruction separator 1 are stopped, and the lid 1g of the container 1a is opened with the rotation of the impact wing 1n stopped. Then, the object 6 to be processed after impact destruction is taken out from the discharge port 12 onto the conveyor 3.
At this time, the dust collector 2 is actuated again, and a small amount of powder 30 floating in the hood F with a predetermined suction force can be collected from the second suction port 13 of the discharge port 12 through the suction duct 15. .

Next, the conveyor 3 and the sieve machine 4 are started.
At this time, the conveyor 3 puts the object to be processed 6 into the container 4c of the sieving machine 4, and the sieving machine 4 swings in the direction of the arrow R to vibrate the object to be processed 6 and filters 4g and 4h. The powder 30 remaining on the workpiece 6 is stored in the lower storage container 4r via 4x.

Further, the object to be processed 6 is sorted in the rooms 4i and 4j according to the size by the filters 4g and 4h, and further filtered through the filter 4x, whereby debris and the like of the object to be processed 6 are stored in the storage container 4a. Can be prevented.
Further, the powder 30 floating in the sieve machine 4 is collected by the dust collector 2 through the suction port 15 through the suction duct 15, and even a very small amount of powder 30 can be collected. ing.

  Therefore, in the method of using the metal catalyst destructive recovery apparatus of the first embodiment, the recovery container 1a, the impact wing 1n, the reflectors 1h and 1p, and the air flow A are located above the powder 30 containing the metal catalyst in the container 1a. It acts as a floating means for floating in the water and produces an effect that the powder 30 can be collected easily and in a short time.

  Further, after the impact breakage, the rotational speed of the impact blade 1n is reduced to promote the separation of the workpiece 6 and the powder 30, or flows into the first suction port 1e from the atmosphere opening port 11 upward in the container 1a. By forming the air flow B, the powder 30 can be efficiently recovered in a short time.

  Furthermore, since the suction force of the dust collector 2 is controlled in accordance with the state of generation of the powder 30 floating in the container 1a, the dust collector is used in a situation where the powder 30 is low as in the initial stage of impact destruction of the object 6 to be treated. The power consumption cost can be kept low by lowering the suction force of 2, and the suction force of the dust collector 2 is gradually increased in a situation where the object 6 is gradually impacted and the powder 30 gradually increases. As a result, the powder 30 can be efficiently recovered in a short time.

  Further, the second suction port 13 of the dust collector 2 is provided at the discharge port 12 for taking out the target object 6 after impact destruction from the container 1a, or the target object 6 is sieved by the sieve machine 4 before the impact destruction. The powder 30 contained in the object to be processed 6 can be recovered almost completely.

Embodiment 2 of the present invention will be described below.
FIG. 8 is a general view of a method for using the metal catalyst destructive recovery apparatus of Example 2 of the present invention, FIG. 9 is a side sectional view for explaining the inside of the destructive separator of Example 2, and FIG. It is a disassembled perspective view of a member.
FIG. 11 is a perspective view of a filter member according to the second embodiment, FIG. 12 is a diagram illustrating an internal state of the destructive separator according to the second embodiment, and FIG. 13 is a diagram illustrating an operation of the destructor according to the second embodiment. .

  In addition, the usage method of the metal catalyst destruction recovery apparatus of Example 2 is the same as that of Example 1 except that the sieving machine described in Example 1 is omitted and the configuration of the destruction separator is partially changed. Since they are substantially the same, only the differences will be described in detail, and the same constituent members will be denoted by the same reference numerals and description thereof will be omitted.

  As shown in FIG. 8, in the method of using the metal catalyst destructive recovery apparatus of the second embodiment, the destructive separator 1 and the dust collector 2 are the main components.

  As shown in FIG. 9, the destructive separator 1 of the present embodiment is provided with a first suction port 19 in the upper central portion of the container 1a instead of the first suction port 1e described in the first embodiment. A filter member 41 connected to the suction duct 2a is attached. Further, the air opening of the lid 1c is omitted.

  Moreover, the sensor part 14 for monitoring the generation | occurrence | production state of the powder 30 in the container 1a is provided in the upper corner | angular part in the container 1a.

  The sensor 14 part is electrically connected to a control unit that controls the rotational speed of the suction motor of the dust collector 2, and further includes a camera for photographing the inside of the container 1a and an analysis part. The analysis unit forms a grid of camera images in advance, and counts the number of grids that change color when the powder 30 floats in the container 1a as the demolition separator 1 starts operating, to determine the increase in the powder 30. It is detected and transmitted to the dust collector 2.

  On the other hand, the control unit of the dust collector 2 changes the amount of increase in the rotational speed of the suction motor in accordance with the increasing state of the powder 30 received from the sensor unit 14, and thereby the suction force of the dust collector 2 is changed over time. It is controlled to gradually increase.

  In other words, the second embodiment is the same as the first embodiment in that the suction force of the dust collector 2 is controlled in accordance with the generation state of the powder 30. Since it is changed according to the increase state, finer control according to the generation state of the powder 30 is possible regardless of the type and amount of the object 6 to be processed.

As shown in FIGS. 10 and 11, the entire filter member 41 is formed in a columnar shape, and a disc-shaped rear surface portion 41a and a bottomed cylindrical main body portion 41b are welded and formed integrally. The member 41 is fixed to the upper center position of the container 1a with bolts (not shown) at four mounting holes 41c provided in the rear surface portion 41a.
The rear surface portion 41 a is formed with an opening 43 having the same opening area as that of the first suction port 19.
In addition, a plurality of suction holes 42 are provided on the outer peripheral surface of the main body portion 41 b, and the sum of the opening areas of the suction holes 42 is at least larger than the opening area of the first suction opening 19, and the powder 30 The suction performance is not lowered.

The inner wall 1d is provided with a blower opening 44 opened in the shape of a long hole, and the blower opening 44 is connected to a connection pipe 45 provided along the circumferential direction of the inner wall 1d while being inclined downward. .
In addition, although illustration is abbreviate | omitted, the connection pipe 45 is connected to an air blower, and the air outlet 44 is provided with a flap and a filter for preventing backflow.

Hereinafter, the operation and effect of the method of using the metal catalyst destructive recovery apparatus of Example 2 will be described.
When the destructor / separator 1 is operated in the method of using the metal catalyst destructive recovery apparatus of the second embodiment, as shown in FIG. 12, the impact wing 1n rotates and the air supplied from the air tube 1v becomes It injects toward the inner wall 1d of 1a, As a result, the air flow A which goes upwards in the container 1a generate | occur | produces.

  Further, when air is blown from the air blowing port 44, a vortex Y descending downward along the inner wall 1d is generated in the container 1a.

  When the workpiece 6 is impact-destructed under such circumstances, as shown in FIG. 13, relatively large solid particles such as dust and debris and powder are added in the container 1a due to the rotational force of the impact wing 1n. A forced vortex is generated by a multiphase flow with the body 30.

  Dust and debris that are heavier than the powder 30 tend to gather below the inner wall 1d due to the centrifugal force of the forced vortex and gravity, and are collected from the first suction port 19 via the suction hole 42 of the filter member 41. Only the body 30 can be recovered very efficiently.

When a rotating body that generates a vortex is provided in the container 1a, irregular movement of a minute part of the fluid is restricted in the vicinity of the inner wall 1d. The powder 30 remaining in the broken pieces is not separated.
However, in the second embodiment, since the vortex Y is formed by the air blowing from the air outlet 44 of the inner wall 1d, the broken pieces gathered on the inner wall 1d like the Rankine vortex are continuously affected by the vortex Y, resulting in the breakage. The powder 30 remaining in the piece separates and floats.
Moreover, a turbulent flow is generated by the vortex flow Y and the air flow A, and it becomes easy to stir the object 6 to be processed in the container 1a during impact destruction.

  In addition, as described above, the dust collector 2 controls the suction force by gradually increasing the rotation speed of the suction motor based on the generation state of the powder 30 by the sensor unit 14. In the situation where the powder 30 floating in the container 1a is small as in the initial stage of destruction, the suction power of the dust collector 2 can be reduced to reduce the power consumption cost, and in the situation where the powder 30 increases, the dust collector By gradually increasing the suction force, the powder 30 can be efficiently recovered in a short time.

  Further, the amount of increase in the suction force can be appropriately controlled while monitoring the powder 30 floating in the container 1a with the sensor unit 14, and it is fine regardless of the type and amount of the object 6 to be processed put into the container 1a. Control becomes possible.

  Moreover, since the powder 30 does not remain in the target object 6 after impact destruction, almost all of the powder 30 contained in the target object 6 before impact destruction can be recovered, and the sieving machine is omitted. Can do.

  Since the other operations of the impact breaker 1 and the dust collector 2 are the same as those in the first embodiment, the description thereof is omitted.

  Further, the rotational direction of the vortex Y described in the second embodiment can be appropriately set in consideration of the rotational direction of the impact blade 1n.

  Although the embodiments of the present invention have been described above, the specific configuration of the present invention is not limited to the embodiments, and the present invention includes any design changes that do not depart from the gist of the invention. It is.

  For example, the final suction force of the dust collector 2, the suction time, the amount of change in the suction force when the suction force is gradually increased, and the like can be set as appropriate.

Moreover, the sensor part 14 should just be what can monitor the increase condition of the powder 30 which floats in the container 1a, and it can substitute for the method for detecting the powder 30 with various sensors.
Further, when the object to be treated 6 contains a lot of liquid components and the powder 30 does not float as desired in the container 1a and the amount of increase is unstable, the suction force of the dust collector 2 is used. There is also a case where control is performed so as to move up and down.

  Further, the shape and the number of installed impact feathers 1n can be set as appropriate.

  Further, various types of filters may be provided at locations where the powder 30 containing the metal catalyst passes in the destructor 1, the dust collector 2, and the sieve 4.

  Furthermore, the method of using the metal catalyst destructive recovery device of the present invention includes a chromium-based stainless steel automobile catalyst, a nickel-based stainless steel chemical plant catalyst, a ceramic catalyst, etc. It can be applied to various catalysts supported on the carrier, and it is naturally conceivable that the presence or absence of the reflectors 1h and 1p and the number of them are appropriately selected according to the type of the catalyst.
