Definitions
- the present invention relates to devices and methods of the "push-pull" type adapted to evacuate toxic vapors or powders or other gases and powders during the handling of a weighing operator or equivalent and concerns in particular a device for extracting toxic vapors or powders and the method of implementation.
- aeration systems which are generally extraction hoods such as front hoods, capture arms or sheaths previously perforated.
- a front hood sucks the vapors or powders coming out of the containers releasing the toxic vapors or powders thanks to a suction mouth located behind the containers at a distance which requires that the hood has a high flow and a height sufficient to suck the vapors or powders released by containers of variable size.
- the system using the extraction arms also called capture arms, allows the extraction of toxic vapors or powders at the source.
- this system has the same types of disadvantages as hoods, especially the need for an oversized flow resulting in significant energy consumption.
- the arms can hinder the operator in his work.
- they require manual positioning by the operator. There is thus no serious guarantee of the protection of it.
- the best device is the so-called "push-pull device" In which there is an opening or a blower nozzle for blowing air and entraining toxic vapors or powders towards the opening or the suction nozzle, guaranteeing air velocities of at least 0.5m / s.
- Such a "push-pull” device is described in document US2006009147A1.
- This device is used to extract toxic vapors from the surface of an open-surface reservoir such as a tank containing an electrolyte used in an electrolysis process or for an acid etching process.
- the tank being fixed, the openings or nozzle for blowing and suction are fixed relative to the tank and the device operates continuously. Therefore, the device described can not be used when the container exhaling toxic vapors or powders can be of variable height as is the case in weighing and has the major disadvantage of spending considerable energy since it operates in permanently.
- a device for the extraction of contaminated gas with or without particles includes a nozzle on the side of the source of contaminated gas that generates a stream of gas entraining and deflecting the contaminated gas to an extraction device. Similarly in this application, the nozzle and the extraction device are fixed and the device operates continuously.
- the main object of the invention is to provide a device for extracting toxic vapors or powders by blow-suction, also called - "push-pull", to evacuate toxic vapors or powders whatever the size of the container containing products exhaling these vapors or powders.
- Yet another object of the invention is to provide a process for extracting toxic vapors or powders by blowing-suction for discharging vapors or toxic powders automatically without requiring action by the operator.
- Another more specific object of the invention is to provide a device as above in which the container exhaling toxic vapors or powders is placed on a weighing device or an equivalent device.
- the main object of the invention is therefore a device for extracting toxic vapors or powders used with a product handling device on which is placed a container containing products exhaling toxic vapors or powders, the extraction device comprising blowing means for blowing air for entraining toxic vapors or powders and suction means for sucking air containing the toxic vapors or powders, said blowing and suction means being actuated by means of drive, such as a motor, for raising or lowering the blowing and suction means.
- the product handling device comprises a tray adapted to install an open container of variable size opaque or translucent exhaling vapors or toxic powders.
- the extraction device is characterized in that:
- the air blowing means is a blowing nozzle for blowing air at the open surface of the container, the blowing being actuated when the nozzle is placed in front of the open surface
- the suction means is a suction nozzle for sucking up the air charged with toxic vapors or powders blown by the blast nozzle, the suction being actuated when the nozzle is placed in front of the open surface
- the extraction device comprises means for detecting the container placed on the tray of the product handling device, the nozzles being placed on the open upper surface of the container in response to the detection means,
- the extraction device further comprises a safety means adapted to stop the means for driving the nozzles when one and / or the other of the nozzles is blocked by an unforeseen obstacle.
- a second subject of the invention is a process for extracting toxic vapors or powders implemented in the above device, comprising the following steps:
- Figure 1 shows schematically the device for extracting toxic vapors or powders used with a weighing device
- FIG. 2 is a diagrammatic representation of the scale plate on which a vapor-exhaling container is placed. or toxic powders and blowing and suction nozzles;
- FIG. 3A schematically represents the blowing nozzle showing the air blowing holes as well as the presence detector
- Figure 3B schematically shows the suction nozzle showing the triangular slot to suck the toxic vapors and the reflector
- Figure 4 schematically shows a front view of the motor and the worm for moving up and down the blowing and suction tubes in a preferred embodiment
- Figure 5A schematically shows a side view of the integral assembly of the worm and blowing tubes and suction when there is no unforeseen obstacle preventing the descent of the tubes;
- Figure 5B schematically shows a side view of the integral assembly of the worm and blow tubes and suction that are no longer integral when there is an unforeseen obstacle preventing the descent of the tubes;
- Figure 6 shows schematically a particular embodiment of the blowing and suction nozzles
- Figure 7 schematically shows a particular embodiment of the suction nozzle.
- a device for extracting toxic vapors or powders is used with a weighing device comprising a scale 10 placed on a table 12. During a weighing, the operator places a container containing products exhaling toxic vapors or powders on the weighing pan 10. Note that the container (not shown) may be any size, and be opaque or translucent.
- the extraction device of the "push-pull" type comprises two nozzles, a blast nozzle 14 and a suction nozzle 16.
- the blast nozzle 14 blows air so as to entrain the toxic vapors or powders which are sucked by the suction nozzle 16.
- the blast nozzle 14 and the suction nozzle 16 are placed on either side of the open surface 18 of a container 20 placed on the plate of the scale 10. The air is blown through the blast nozzle 1 and the air entraining the vapors or toxic powders is. sucked by the suction nozzle 16.
- blowing nozzles 14 and the suction nozzles 16 are respectively at the end of aeraulic tubes 22 and 24.
- the tubes 22 and 24 open into ducts, respectively the ducts 26 and 28.
- the rise or the descent of the tubes is actuated by an actuating means which is generally a motor.
- the air blown through the tube 22 and the blast nozzle 14 comes from a suitable blowing means and the air entraining the toxic vapors or powders in the suction nozzle 16 and the tube 24 is sucked by a means of blowing. adequate suction.
- the blowing and suction means can be combined into a single integrated fan 32.
- the fan 32 may be placed above a false ceiling 40 so as to limit noise.
- valves (not shown) are placed on the portion of the tubes located above the false ceiling 40 so as to adjust the desired flow rates.
- This fan when in operation, draws vapor-laden air upwards.
- the airflow is then divided into two parts.
- a first part 34 is evacuated at the exit 36 of the sheath 28 while a second portion 38 is sent down the tube 22 and the blowing nozzle 14.
- the portion 38 sent into the tube 22 and blown by the The blast nozzle 14 is smaller than the portion 34 discharged at the outlet, and preferably represents 5% of the air charged with the toxic vapors received by the tube 24.
- the fan is preferably EC technology (switched electronics, very low energy consumption), which allows to integrate the device on any ventilation network, even those initially not designed to connect extraction equipment. This fan limits the total flow extracted to the extent that the air blown is taken from the extracted air.
- the device comprises two fans: a first fan for blowing air into the nozzle 14 and a second fan for extracting air through the nozzle 16.
- the blast nozzle 14 has openings, for example slits 42 as shown in the figure, for passing a horizontal laminar air flow directed towards the open surface. 18 of the container 20 as described with reference to Figure 2. These slots have a height of 1mm and extend over a length of 200mm. These slots are framed inside the tube blowing by 4 sides with a depth of 10mm, thus producing a laminar air flow at the exit from the nozzle. Note that the blowing openings allowing air to pass could have any other shape.
- the suction nozzle 16 has a slot 44 adapted to receive the flow of air and vapors or powders.
- the slot 44 has a shape, in particular triangular, such that the flow rate of the air entering the suction nozzle is the same regardless of the distance from the elbow of the tube 24 which is upstream of the nozzle. suction.
- the blast nozzle 14 has a presence detector 46 placed under the holes 42, and the suction nozzle 16 illustrated in FIG. 3B comprises a reflector 48 placed under the slot 44.
- presence detector 46 transmits an electromagnetic signal, preferably an infra-red signal, which is reflected by the reflector 48.
- the nozzles are in the low position at the balance as will be seen later, and therefore the container blocks the signal transmitted by the presence detector 46. This signal is no longer reflected by the reflector 48 received in return by the presence detector 46. The device extraction therefore knows that a container has just been placed on the scale plate.
- the presence detector assembly 46 and reflector 48 may be replaced by any equivalent means and in particular an ultrasonic detector instead of the infrared detector.
- the ultrasonic signal is returned to the detector, which allows the detector to know the reduced distance separating it from the container and thus to determine that a container has just been placed.
- the means for actuating the ventilation tubes is a motor 30 which is preferably a DC motor or a stepper motor provided with a worm 50 secured to an attachment 52 which actuates the tubes 22 and 24.
- the start of the motor 30 causes the rotation of the screw 50 and the raising or lowering of the attachment 52.
- the worm 50 instead of the worm 50, one can use a winch of which the cable is guided by pulleys to ensure the descent or rise of the tubes 22 and 24, or even a belt guided and driven by pulleys to also ensure the descent or rise of the tubes 22 and 24.
- the tube actuator includes an improved mechanism preventing the tubes from further descending if they encounter an obstacle, such an obstacle being the container that is poorly positioned or the hand of the operator.
- the attachment 52 is composed of a magnet 54 which is fixed on a ring 56 itself attached to the worm 50.
- the attachment 52 fixed to the air flow tubes comprises a steel element 58 which is magnetically bonded to the magnet 54.
- the steel member 58 ceases to be magnetically bonded to the magnet 54 because a higher resistance to a defined force due to the magnet is applied.
- a contact sensor (not shown) on the magnet 54 sends a signal which is intended to reverse the direction of rotation of the motor to raise the blow tubes and suction to a high position of safety and allow the operator to stop this incident by removing the obstacle 60.
- the normal cycle will resume after voluntary action of the operator.
- a push button type actuator not shown in the diagrams is integrated on the side of the blowing nozzle 14. After actuation of the button by the user, the tubes 22 and 24 are repositioned in the low position.
- the security means that has just been described aims to protect the user as well as the equipment. It is faster and more reliable than detecting the increase in motor intensity. It can even decouple the motor from the tubes and avoid crushing if the automation fails.
- FIG. 6 shows a particular embodiment in which the blowing nozzle 14 and the suction nozzle 16 are not placed on the sides of the plate 10 of the product handling device but at the front and rear of the tray of the product handling device. fact that manipulations are easier for some operators.
- FIG. 7 represents a particular embodiment in which the suction nozzle 16 is of rectangular shape and of a greater height enabling it to capture the peripheral vapors thanks to the slots 62 lying over the entire height in the case where these vapors are emitted by a second bottle held in the hand of the operator.
- the process for extracting toxic vapors or powders according to the invention is as follows. First, after the power is turned on and when no container has been placed on the weigh scale plate 10, the device is in standby mode.
- the motor 30 lowers the tubes 22 and 24 in the lower position, that is to say with the nozzles 14 and 16 to. level of the scale plate, until the end of the low end is triggered.
- the presence detector 46 detects its presence. When the container is detected for a predetermined time, for example more than 2s, the device goes into positioning mode.
- the motor 30 causes the tubes 22 and 24, and at the same time the nozzles 14 and 16, to rise until the detector 46 no longer detects the presence of the container. which means that the nozzles are placed just above the level of the open surface of the container. The motor 30 then down the tubes until there is again detection of the container by the detector 46.
- the engine stops and the ventilation is switched on. For this, the fan 32 is started.
- the operator can now carry out the weighing safely since the toxic vapors or powders are extracted by the tube 24.
- the suction flow rate in the tube 24 is set once and for all thanks to a potentiometer, and the blowing flow rate. in the tube 22 is regulated by a blowing valve.
- the detector 46 detects the absence of a container and, after a predetermined time, for example 2s, it causes the tubes 22, 24 and the nozzles 14, 16 to come down. low position.
- a high limit switch and a low end position sensor (not shown).
- the engine is cut when there is detection of high end and low end of stroke.
- an intensity sensor and a fuse are placed on the motor starter so as to detect overconsumption and causing the motor 30 to stop before it is damaged.
- a pressure sensor in the tube measures the pressure difference with the atmospheric pressure. The operator is warned in case this pressure difference exceeds a certain threshold. Thus, the operator is able to know at any time if the ventilation is in working order and can apply the appropriate safety procedure defined in this case.
- the operation control of the motor 30 is performed by a controller which integrates a program taking into account the information received by the various detectors and sensors mentioned above. Note that this controller can be connected to a wireless network type WIFI or Ethernet cable to retrieve information on the energy performance of the device but also on the state of different sensors and actuators to perform a remote diagnosis in case of malfunction. Several machines can be connected to a centralized supervision system which records all the states and reports alarms in case of malfunction.
- a particular mode of maintenance allows the blowing nozzles 14 and suction 16 to mount in the up position to allow for example maintenance operations on the balance or cleaning without inconvenience to the user.
- vial detection is disabled and ventilation is shut off.
- This mode is controlled by a pushbutton type actuator placed on the side of the blowing nozzle 14 and not shown in the diagrams.
- the device and the process for extracting toxic vapors or powders described above are particularly suitable in the field of perfumery where the raw materials used to compose the perfumes are more harmful than one might think. Indeed, various varieties of chemicals, most often toxic such as acetone, are handled daily by operators. In addition, there are still products whose risks remain poorly known to date.
- ATEX explosive atmosphere zone
- the method of extraction of toxic vapors or powders which has just been described can be used in all types of airflow network, including those with weak available pressures of type VMC (controlled mechanical ventilation).
