Description

Press mold for incineration brick molding {Press mold for making block with incinerated materials}

The present invention relates to a press molding machine for forming bricks of incineration materials.

Conventionally, many household wastes generated in cities have been landfilled, but it is difficult to secure landfill sites, and it is a source of leachate from the landfill and a source of heavy metal pollution. The amount of waste is also being reduced.

However, incineration ash, the residual waste remaining after incineration of combustible waste, contains a large amount of heavy metals despite the significant decrease in volume, which makes it difficult for the landfill to be disposed of.

For this reason, a method of recycling incineration materials generated in incinerators has been proposed as a material for building materials such as bricks and aggregates.

In order to mold hard bricks using incineration materials, they must be compression molded using presses, but incineration materials are difficult to form by themselves because they do not have cohesive force between them.

For this reason, after adding a treating agent such as a curing agent and a mixing agent to the incineration ash, the incineration ash is stirred and fed to a press molding machine to be taken out with a brick or the like.

Is to transfer the incineration ash to the press molding machine 106 side.

The incineration ash discharged from the outlet 107 of the screw feeder 105 is filled in the mold 108 of the press forming machine 26 and the ram 109 is pressed downward in the upper portion to form a brick.

However, according to the conventional method described above, it was inconvenient to supply the incineration material from the screw feeder 105 to the molding die 108 of the press molding machine 106, and the brick 110 having the molding completed was removed from the molding die 108. In order to send it to the heating curing room 111, which is a drying apparatus, a worker is arranged to pick up the mold 108, and then turn the brick 11 onto the conveyor belt device 112. There is a problem that the increase in brick manufacturing costs due to the disturbance and workability is reduced.

Therefore, the present invention has been proposed in view of the above points, and its purpose is to automatically supply the incineration material mixed with the treatment chemical to the molding die, and to remove the finished brick from the molding mold and discharge it to the next process.

The operation of the present invention will be described below.

The incineration ash generated in the waste incineration plant is primarily stored in the incineration ash storage tank 1 and then supplied to the basket conveyors 7a and 7b through the transfer mechanisms 2, 3 and 5 in various stages. When the motor M of the one-sided bucket conveyor 7a rotates, the chain 34a is driven, and the baskets 35a spread the incineration ash. When the bucket 35a passes over the upper chain gear 32a, it is inverted and inverted so that the incineration material contained therein may be poured into the first hopper 10a of the first stirrer 17 or directly through the screw conveyor 8. do. At this time, as shown in Figure 1 by a meter (9) a certain amount of incineration ash is injected into the first hopper (10a). When a certain amount of incineration material is filled in the first hopper 10a, the motor M stops driving, and the hardener chemicals and the mixed chemicals stored in the chemical storage tanks 11 and 12 are pumped by the pumps 13 and 14. A certain amount is supplied to the first hopper 10a through the flow rate control valves 15 and 16 by a predetermined amount, that is, the amount of incineration ash injected into the hopper 10a.

Similarly, with a slight time difference, the motor M of the bucket conveyor 7b is driven so that the incineration ash and the treatment chemical are similarly supplied to the second hopper 10b of the second stirrer 18.

When the mixed material (incineration material + treatment chemical) in the first hopper 10a pushes the opening / closing door 41a by the solenoid 40a operation and the hole 42a is opened, the center portion of the first cylindrical case 36a, that is, two stirrings The blades are dropped and supplied to the blades 38a and 39a.

When the supply of the mixture to the first stirrer 17 is completed, the power supply to the solenoid 40a or the pneumatic actuating cylinder is cut off, and the operating rod returns to its original position to close the opening and closing door 41a.

When the open / close door 41a is closed, the forward / reverse drive motor M1 initially rotates forward. When the motor M1 rotates forward, the mixed material injected near the central spiral blades of the first rotary shaft 37a rotates the outer circumference of the rotary shaft 37a in a spiral direction by the spiral blades 38a and 39a opposite to each other. The incineration ash and the treatment chemical are evenly stirred as it is transferred to. When the mixed material reaches both ends, the motor M1 is driven to rotate in reverse. Accordingly, the mixed material driven to both ends is transferred to the center of the rotating shaft 37a again, and both sides collide at the central boundary to further increase the stirring effect.

When the forward and reverse driving of the motor M1 is repeated for about 15 minutes, the incineration ash and the treating chemical are completely stirred while reciprocating in the apparatus.

On the other hand, the first hopper of the first stirrer 17, which is empty in the latter part of the stirring operation, is again put into the incineration ash by a basket conveyor, and the chemicals are supplied through the flow control valves 15 and 16.

After the stirring is completed for about 15 minutes through the first stirrer 17 (referring to the stirred mixture), the opening and closing door 45a installed under the first cylindrical case 36a is opened by the solenoid 46a operation. When it is accommodated in the stirring water receiving tank 19 through the guide path (43a) through the inlet 47 of the screw feed mechanism 20 is continuously introduced into one end of the cylindrical case (49).

When the agitated material is introduced, the motor M2 is driven to rotate. Accordingly, the agitated material is axially transferred by the screw shaft 50 and then supplied to the metering vessel 23 of FIG. 4 through the outlet 48 at the end. It will be done.

When the agitated material dropped down in the incineration ash measuring vessel 23 reaches the weight of the brick to be molded, the electronic balance 50 measures the weight and outputs a signal. The control unit 66 receives the signal. ) Causes the motor M2 of the screw feed mechanism 20 to stop driving and simultaneously operate the actuator 53 (see FIG. 9).

When the actuator 53 is actuated and the actuating rod 54 is pulled out (or the actuation rod pulls the container), as shown in FIG.

At this time, the incineration ash transport container 24 is located below it to accommodate the agitated pouring.

Next, the control unit 66 operates the actuator 25 so that the operating rod 56 pushes the incineration ash transport container 24.

In this way, the incineration ash transfer container 24 slides on the base plate member 55 and stops at the upper portion of the molding die 27.

When the incineration ash transport container 24 stops at the upper portion of the molding die 27, the base plate member 55 thereunder is an empty space, so that the stirring material in the incineration ash transport container 24 falls into the mold 27. (FIG. 6).

In the next moment, the working rod 56 of the actuator 25 is retracted to return the incineration ash conveying container 24. When the upper and lower cylinders 62 and 63 of the press molding machine 26 operate, the upper and lower plate members 58 ( As the 59 is lowered and raised, the pressure members 60 and 61 enter the molding die 27 to compress the stirring material.

When the stirring is compressed, the incineration material mixed with the chemical is firmly agglomerated and formed into a brick shape along the shape of the molding die (see FIG. 7).

When the brick forming is completed, the upper pressurizing member 60 is quickly raised by the operation of the upper cylinder 62, and the lower pressurizing member 61 is raised by the operation of the lower cylinder 63 to raise the brick 67. Out of the mold 27, the lower surface thereof reaches the same horizontal surface as the base plate member 55, the operation of the lower cylinder 63 is stopped, and the control unit 66 operates the actuator 25 to incinerate the incineration ash measuring container 24. Advance)

When the incineration ash measuring container 24 advances and approaches the molding mold 27, the incineration ash measuring container 24 is pushed to push the brick 67 which is molded and protrudes upwards (see FIG. 8). Thus, the brick 67 pushed backward by the measuring container is thus pressed. The hard incinerator brick is formed by flowing into the heating curing chamber 29 installed next to the press molding machine 26 and curing after being dried.

On the other hand, when the discharge of the brick 67 is completed, the incineration ash conveying container 24 is moved back to the metering container 23 downward position by the actuator 25 operation and stirred from the screw conveying mechanism 20 to the measuring container 23. The water will be supplied again and the process described above will be repeated.

According to the present invention as described above, since the incineration material mixed with the treatment chemical is weighed through the measuring container before being fed to the press molding machine by the transfer mechanism, it is possible to control the precise amount and ensure the uniformity of the quality, base plate It is possible to safely supply the incineration ash measured by the weighing container to the molding die by using the incineration ash transporting container which reciprocates on the member, and also to easily transfer the finished brick to the next step process, thereby greatly increasing the efficiency of the facility. There is.
