A first filter screen is provided inside the conical separation shell. This utility model improves upon existing technology by effectively cleaning the silica entrained in the waste gas during the waste gas treatment process, facilitating pollution-free emission of the waste gas, and also removing particles entrained in the waste gas, further improving the waste gas treatment effect.

[0004] While existing technologies can treat the waste gas generated during silicone production, their filtration efficiency gradually decreases over time because it is inconvenient to replace the activated carbon layer. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas treatment device for silicone production, which solves the problem in the prior art that it is inconvenient to replace the activated carbon layer, and therefore the filtration efficiency of the waste gas will gradually decrease over time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste gas treatment device for silicone production includes a treatment box, a treatment tank fixedly installed inside the treatment box, and a filter assembly installed inside the treatment tank.

[0008] The filtration assembly includes an atomizing nozzle, a filter screen, a movable chute, a positioning groove, an activated carbon filter plate, a retaining strip, a helical spring, retaining teeth, a gear, and a rotating handle. The atomizing nozzle is fixedly connected to the inside of the treatment tank, the filter screen is fixedly installed inside the treatment tank, the movable chute is formed on the inner wall of the treatment tank, the positioning groove is formed on the inner wall of the movable chute, the activated carbon filter plate is snapped into the inside of the movable chute, the retaining strip is slidably installed inside the activated carbon filter plate, the helical spring is fixedly connected to the end of the retaining strip away from the movable chute, the retaining teeth are formed on the side surface of the retaining strip, and a gear is meshed with the outer side of the retaining teeth. The rotating handle is rotatably connected to the front of the activated carbon filter plate.

[0009] Preferably, the top of the treatment tank is provided with an air outlet assembly, which includes an air outlet duct, a strip grille and a ventilation fan, with the air outlet duct fixedly connected to the top of the treatment tank.

[0010] Preferably, the strip grid is fixedly connected to one end of the air outlet duct near the treatment tank, and the ventilation fan is fixedly connected inside the air outlet duct and located above the strip grid.

[0011] Preferably, a vibration assembly is provided below the filter screen. The vibration assembly includes a vibration chute, a helical spring, and a vibration motor. The vibration chute is located below the filter screen and on the inner wall of the treatment tank.

[0012] Preferably, the second helical spring is fixedly connected inside the vibrating groove, the top of the second helical spring is fixedly connected to the filter screen, and the vibrating motor is fixedly installed on the top of the filter screen.

[0013] Preferably, an air inlet pipe is fixedly connected to the right side of the treatment tank, a storage slot is provided at the bottom of the treatment box, an observation glass is fixedly connected to the front of the storage slot, a door is rotatably installed on the front of the treatment box, and the treatment tank is connected to the storage slot.

[0014] This utility model has the following beneficial effects:

[0015] The filter assembly is designed so that when exhaust gas enters the treatment tank, the operator activates the atomizing nozzle to spray water mist, humidifying larger particles in the exhaust gas and causing them to fall to the bottom of the treatment tank. Harmful gases in the exhaust gas are then adsorbed by the filter screen and activated carbon filter plate, thus purifying the exhaust gas. When the activated carbon filter plate needs replacement after prolonged use, the operator rotates the handle, which drives the gears. During rotation, the gears mesh, moving the retaining strip. After moving a certain distance, the retaining strip disengages from the positioning slot, and pulling the handle removes the activated carbon filter plate. To replace the new activated carbon filter plate, it is simply inserted into the moving slide. Because the end of the retaining strip that engages with the positioning slot is curved, it automatically expands and contracts, automatically locking the activated carbon filter plate in place, thus completing the installation. This design not only effectively purifies the exhaust gas but also facilitates the replacement of the activated carbon filter plate, significantly improving practicality and convenience.

[0016] The vibration assembly is designed so that the atomizing nozzle sprays water mist, which causes particulate matter from the exhaust gas to adhere to the lower surface of the filter screen due to moisture. Therefore, by starting the vibration motor to drive the filter screen to vibrate, the particulate matter attached to the lower surface of the filter screen can be shaken off, thereby preventing the filter screen from becoming clogged.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-5 A waste gas treatment device for silicone production includes a treatment box 1, a treatment tank 2 fixedly installed inside the treatment box 1, and a filter assembly 3 installed inside the treatment tank 2.

[0026] The filter assembly 3 includes an atomizing nozzle 301, a filter screen 302, a movable chute 303, a positioning groove 304, an activated carbon filter plate 305, a retaining strip 306, a spiral spring 307, a retaining tooth 308, a gear 309, and a rotating handle 310. The atomizing nozzle 301 is fixedly connected to the inside of the processing tank 2. The filter screen 302 is fixedly installed inside the processing tank 2. The movable chute 303 is opened on the inner wall of the processing tank 2. The positioning groove 304 is opened on the inner wall of the movable chute 303. The activated carbon filter plate 305 is snapped into the inside of the movable chute 303. The retaining strip 306 is slidably installed inside the activated carbon filter plate 305. The spiral spring 307 is fixedly connected to the end of the retaining strip 306 away from the movable chute 303. The retaining tooth 308 is opened on the side surface of the retaining strip 306. The gear 309 is meshed with the outer side of the retaining tooth 308. The rotating handle 310 is rotatably connected to the front of the activated carbon filter plate 305.

[0027] The filter screen 302 is located above the atomizing nozzle 301, and the movable slide 303 is located above the filter screen 302. The retaining strips 306 are symmetrically distributed left and right, and each retaining strip 306 is locked at one end of the positioning groove 304, with one side being curved. The other end of the spiral spring 307 is fixedly connected to the inside of the activated carbon filter plate 305. The rotating handle 310 is fixedly connected to the gear 309. With this filter assembly setup, when exhaust gas enters the treatment tank 2, the operator activates the atomizing nozzle 301, causing it to spray water mist to humidify larger particles in the exhaust gas, causing them to fall to the bottom of the treatment tank 2. Harmful gases in the exhaust gas are then adsorbed by the filter screen 302 and the activated carbon filter plate 305, thus purifying the exhaust gas. Furthermore, the activated carbon filter plate 305 requires replacement after prolonged use. When replacing the activated carbon filter plate 305, the operator can rotate the handle 310 to rotate the gear 309. During the rotation, the gear 309 engages and moves the locking strip 306. After moving a certain distance, the locking strip 306 will leave the positioning groove 304. Then, pulling the handle 310 will remove the activated carbon filter plate 305. When replacing the activated carbon filter plate 305, it is directly inserted into the moving slide 303. Since the end of the locking strip 306 that engages with the positioning groove 304 is curved, it can automatically expand and contract, thus automatically locking the activated carbon filter plate 305 and completing the installation. This not only effectively purifies the exhaust gas but also facilitates the replacement of the activated carbon filter plate 305, effectively improving its practicality and convenience.

[0028] Furthermore, an air outlet assembly 4 is provided on the top of the processing tank 2. The air outlet assembly 4 includes an air outlet pipe 401, a strip grid 402, and a ventilation fan 403. The air outlet pipe 401 is fixedly connected to the top of the processing tank 2.

[0029] The strip grid 402 is fixedly connected to one end of the air outlet duct 401 near the treatment tank 2, and the ventilation fan 403 is fixedly connected inside the air outlet duct 401 and located above the strip grid 402; the air outlet assembly is set up so that by starting the ventilation fan 403, it can drive the air in the treatment tank 2 to be quickly discharged through the air outlet duct 401, thereby improving the purification efficiency of the exhaust gas.

[0030] Furthermore, a vibration assembly 5 is provided below the filter screen 302. The vibration assembly 5 includes a vibration slide 501, a helical spring 502, and a vibration motor 503. The vibration slide 501 is located below the filter screen 302 and on the inner wall of the processing tank 2.

[0031] The second helical spring 502 is fixedly connected inside the vibrating slide 501, and the top of the second helical spring 502 is fixedly connected to the filter screen 302. The vibration motor 503 is fixedly installed on the top of the filter screen 302. The vibration assembly is designed so that the atomizing nozzle 301 sprays water mist, which causes particulate matter in the exhaust gas to adhere to the lower surface of the filter screen 302 due to moisture. Therefore, by starting the vibration motor 503 to drive the filter screen 302 to vibrate, the particulate matter attached to the lower surface of the filter screen 302 can be shaken off, thereby preventing the filter screen 302 from becoming clogged.

[0032] Furthermore, an air inlet pipe 6 is fixedly connected to the right side of the treatment tank 2, a storage tank 7 is provided at the bottom of the treatment box 1, an observation glass 8 is fixedly connected to the front of the storage tank 7, a box door 9 is rotatably installed on the front of the treatment box 1, the treatment tank 2 is connected to the storage tank 7, and a discharge pipe for discharging wastewater is fixedly connected to the bottom of the storage tank 7.

[0033] In summary:

[0034] When in use, the staff first places the treatment tank 1 in a suitable position, connects the atomizing nozzle 301 to the tap water pipe, and connects the air inlet pipe 6 to the flow pipe. Then, when the exhaust gas enters the treatment tank 2, the staff starts the atomizing nozzle 301 to spray water mist, which humidifies the larger particles in the exhaust gas and causes them to fall to the bottom of the treatment tank 2. The harmful gases in the exhaust gas are then adsorbed by the filter screen 302 and the activated carbon filter plate 305, thus purifying the exhaust gas. Subsequently, the rotation of the ventilation fan 403 drives the air in the treatment tank 2 to be quickly discharged through the air outlet pipe 401.

[0035] Secondly, when the activated carbon filter plate 305 needs to be replaced after a long period of use, the operator can rotate the handle 310 to drive the gear 309 to rotate. During the rotation of the gear 309, the meshing connection will drive the locking strip 306 to move. When the locking strip 306 moves a certain distance, it will leave the positioning groove 304. Then, by pulling the handle 310, the activated carbon filter plate 305 can be taken out. When replacing the new activated carbon filter plate 305, it can be directly inserted into the moving slide 303. Since the end of the locking strip 306 that is inserted into the positioning groove 304 is arc-shaped, it can automatically expand and contract, so as to automatically lock the activated carbon filter plate 305, thereby completing the installation.

[0036] Finally, because the atomizing nozzle 301 sprays water mist, the lower surface of the filter screen 302 becomes damp and particles in the exhaust gas adhere to it. Therefore, by starting the vibration motor 503 to drive the filter screen 302 to vibrate, the particles attached to the lower surface of the filter screen 302 can be shaken off, thereby preventing the filter screen 302 from becoming clogged.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
