Description

Technical Field

[0001] This invention relates to the field of air purifier technology, specifically to an air purifier for electroplating factories. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts. However, the electroplating production process uses a large amount of chemicals such as strong acids, strong alkalis, salts and organic solvents, which release a large amount of toxic and harmful gases during the operation. These toxic gases can affect the health of workers. Therefore, in order to protect the health of workers, air purifiers are installed in electroplating production workshops to purify the air.

[0003] Existing air purifiers mostly use spraying to treat exhaust gas from electroplating workshops. However, when extracting exhaust gas, dust in the air may get mixed in with the exhaust gas and adhere to the inside of the pipes, making it difficult to clean and even causing blockages. In addition, during the treatment process, water mist mixes with dust in the air and clogs the spray nozzles or filter holes, reducing the treatment effect. Summary of the Invention

A top groove is provided on one side of the sealing groove, and a sealing plate is provided inside the sealing groove. A one-way valve is provided inside the feed inlet.

[0008] Furthermore, a waste liquid chamber is provided at the lower part of the machine body, and a communication port is provided between the deacidification chamber, the dealkali chamber and the waste liquid chamber. A plug is provided in the communication port, and a float is connected to the top of the plug.

[0009] Furthermore, the deacidification chamber and the dealkaliification chamber are symmetrically provided with slots on both sides, and the deacidification chamber and the dealkaliification chamber are provided with a rotating groove on the side near the top groove. The floating plate is slidably connected to the deacidification chamber and the dealkaliification chamber through the slots, and the top groove is connected to the slot on one side of the deacidification chamber and the dealkaliification chamber.

[0010] Furthermore, toothed rods are symmetrically connected to both sides of the float plate, and a slot is provided in the middle of the toothed rod. The toothed rod is slidably connected to the deacidification chamber and the dealkali removal chamber through the top slot.

[0011] Furthermore, a helical gear is provided in the rotating groove, and transmission wheels are symmetrically connected on both sides of the helical gear. The helical gear is meshed with the ring plate through the tooth groove, and the helical gear is intersected with the rack through the slot. The transmission wheel meshes with the rack.

[0012] Furthermore, the lower part of the deacidification chamber and the dealkali removal chamber is provided with an annular groove, and a filter plate is engaged and slidably connected in the annular groove. A top block is provided on one side of the filter plate, and the top block and the top plate are staggered. The annular plate is engaged and rotatably connected to the deacidification chamber and the dealkali removal chamber through the annular groove.

[0013] Furthermore, a limiting rod is provided on the other side of the filter plate, and a vibration spring is provided on the outside of the limiting rod. The limiting rod is engaged and slidably connected with the deacidification chamber and the dealkali removal chamber, and the filter plate is elastically connected to the annular groove through the vibration spring.

The telescopic hose, air inlet pipe, and exhaust hood are all detachably connected.

[0015] This invention provides an air purifier for electroplating factories, which has the following beneficial effects: during use, it can automatically replace the absorbent when it is close to saturation, and can mix the newly added absorbent. During the replacement process, it can clean the filter plates and pipes, preventing dust from adhering to the pipes and filter plates and causing blockage, thus affecting the purification process. Furthermore, it can assist in removing debris during cleaning.

[0016] 1. In use, as the absorbent absorbs harmful substances in the waste gas, its density gradually increases, raising the float. When the absorbent approaches saturation, the float drives the plug to open the connection port and pushes the sealing plate to close the feed inlet, allowing the waste liquid to flow into the waste liquid chamber. In the initial stage of waste liquid discharge, the float, carrying the plug, will always float above the connection port. When the waste liquid level drops to the float, the float will descend with the liquid level, causing the plug to close the connection port and gradually open the feed inlet. New absorbent can then enter the deacidification chamber or dealkali removal chamber through the feed inlet until the absorbent liquid level is flush with the feed inlet, completing the replacement of the absorbent.

[0017] 2. During the use of the device, dust entering with the exhaust gas or suspended matter in the absorbent liquid may adhere to the inner wall of the pipe. When replacing the absorbent liquid, as the float rises, the rack is carried by the float in the top groove and drives the helical gear to rotate in the rotating groove through the transmission wheel. The helical gear drives the ring plate to rotate through the rotating groove. When the ring plate drives the rotating ring through the blade plate, it can drive the scraper to move in the air inlet pipe and the flow pipe. The spiral scraper can move in close contact with the inner wall of the pipe and scrape off the impurities adhering to the inner wall of the pipe. The removed impurities can enter the absorbent liquid with the exhaust gas. The blade plate can push the impurities entering the absorbent liquid downward so that they can be discharged with the waste liquid as soon as possible and reduce residue. When adding new absorbent liquid, as the float descends, the ring plate reverses, which can stir the absorbent liquid and push it upward, accelerating the mixing of the absorbent liquid.

[0018] 3. When the float rises and drives the ring plate to rotate, the ring plate can push the top block through the top plate, thereby causing the filter plate to move in the ring groove and repeatedly vibrate under the action of the vibration spring, shaking off the impurities intercepted by the filter plate and discharging them with the wastewater, thus preventing impurities from clogging the filter plate. When adding new absorbent liquid, the ring plate can drive the filter plate to vibrate the absorbent liquid again, thereby assisting in the mixing of the absorbent liquid.

[0021] Please see Figures 1 to 7 The present invention provides a technical solution: an air purifier for electroplating factories, comprising a body 1 and a cleaning component 4. A deacidification chamber 2 is provided on one side of the body 1, and a dealkali removal chamber 3 is provided on the other side of the body 1. The cleaning component 4 is disposed in the deacidification chamber 2 and the dealkali removal chamber 3. The cleaning component 4 includes an air inlet pipe 401. The air inlet pipe 401 is disposed in the deacidification chamber 2, and a flow pipe 402 is disposed in the dealkali removal chamber 3. The lower ends of the air inlet pipe 401 and the flow pipe 402 are both engaged with a rotating ring 403. A scraper 404 is symmetrically connected to the inner side of the rotating ring 403, and a blade 405 is symmetrically connected to the outer side of the rotating ring 403. A ring plate 406 is connected to the end of the blade 405 away from the rotating ring 403. A top plate 407 is symmetrically connected to one side of the ring plate 406, and a toothed groove 408 is provided on the other side of the ring plate 406.

[0022] Please see Figures 1 to 6The intake pipe 401 and the flow pipe 402 are both L-shaped, and the deacidification chamber 2 and the dealkaliification chamber 3 are connected by the flow pipe 402. The scraper 404 is spiral-shaped, the blades 405 are inclined about the rotating ring 403, the top plate 407 has an arc surface at the top, and the top plate 407 is equidistantly distributed around the ring plate 406. The toothed groove 408 is provided with oblique teeth. The deacidification chamber 2 and the dealkaliification chamber 3 are each provided with a feed inlet 5 on one side, and a sealing groove 6 is provided in the feed inlet 5. A top groove 7 is provided on one side of the sealing groove 6, and a sealing plate 8 is provided in the sealing groove 6. A one-way valve 9 is provided in the feed inlet 5. A waste liquid chamber 10 is provided at the lower part of the machine body 1, and a connecting port 11 is provided between the deacidification chamber 2, the dealkaliification chamber 3 and the waste liquid chamber 10. A plug 12 is provided in the connecting port 11, and the top of the plug 12 is connected to The room has a float plate 13. The deacidification chamber 2 and the dealkaliification chamber 3 are symmetrically provided with slots 14 on both sides. The deacidification chamber 2 and the dealkaliification chamber 3 are provided with a rotating groove 15 on the side near the top groove 7. The float plate 13 is engaged and slidably connected with the deacidification chamber 2 and the dealkaliification chamber 3 through the slots 14. The top groove 7 is connected to the slots 14 on one side of the deacidification chamber 2 and the dealkaliification chamber 3. The float plate 13 is symmetrically connected with toothed rods 16 on both sides. The toothed rods 16 are provided with a hollow groove 17 in the middle. The toothed rods 16 are slidably connected with the deacidification chamber 2 and the dealkaliification chamber 3 through the top groove 7. The rotating groove 15 is provided with a helical gear 18. The helical gear 18 is symmetrically connected with transmission wheels 19 on both sides. The helical gear 18 is engaged with the ring plate 406 through the tooth groove 408. The helical gear 18 is intersected with the toothed rod 16 through the hollow groove 17. The transmission wheels 19 are engaged with the toothed rod 16. The specific operation is as follows: During use, as the absorbent absorbs harmful substances in the waste gas, its density gradually increases, raising the float 13. When the absorbent approaches saturation, the float 13 drives the plug 12 to open the connection port 11 and pushes the sealing plate 8 to close the feed inlet 5, allowing the waste liquid to flow into the waste liquid chamber 10. In the initial stage of waste liquid discharge, the float 13, carrying the plug 12, will always float above the connection port 11. When the waste liquid level drops to the float 13, the float 13 will descend along with the liquid level, causing the plug 12 to close the connection port 11 and gradually open the feed inlet 5. New absorbent can then enter the deacidification chamber 2 or dealkali removal chamber 3 through the feed inlet 5 until the absorbent level is flush with the feed inlet 5, completing the replacement of the absorbent. During the use of the device, dust entering with the waste gas or suspended matter in the absorbent may adhere to the inner wall of the pipe. During liquid collection, as the float plate 13 rises, the rack 16 is carried by the float plate 13 and moves within the top groove 7. It drives the helical gear 18 to rotate within the rotating groove 15 via the transmission wheel 19. The helical gear 18 drives the ring plate 406 to rotate via the rotating groove 15. When the ring plate 406 drives the rotating ring 403 to rotate via the blade plate 405, it can drive the scraper 404 to move within the air inlet pipe 401 and the flow pipe 402. The spiral-shaped scraper 404 can move along the inner wall of the pipe and scrape off the impurities adhering to the inner wall of the pipe. The removed impurities can then enter the absorbent liquid along with the waste gas. The blade plate 405 can push the impurities entering the absorbent liquid downwards, allowing them to be discharged with the waste liquid as soon as possible and reducing residue. When adding new absorbent liquid, as the float plate 13 descends, the ring plate 406 reverses, which can agitate the absorbent liquid and push it upwards, accelerating the mixing of the absorbent liquid.

[0023] Please see Figures 1 to 7 The lower part of the deacidification chamber 2 and the dealkali removal chamber 3 is provided with an annular groove 20, and a filter plate 21 is slidably connected within the annular groove 20. A top block 22 is provided on one side of the filter plate 21, and the top block 22 and the top plate 407 are staggered. The annular plate 406 is rotatably connected to the deacidification chamber 2 and the dealkali removal chamber 3 through the annular groove 20. A limit rod 23 is provided on the other side of the filter plate 21, and a vibration spring 24 is provided on the outside of the limit rod 23. The limit rod 23 is slidably connected to the deacidification chamber 2 and the dealkali removal chamber 3, and the filter plate... 21 is elastically connected to the ring groove 20 through the vibration spring 24. The filter plate 21 is sleeved on the outside of the bottom end of the air inlet pipe 401 and the flow pipe 402. The dryer 25 is set above the dealkali chamber 3 on the machine body 1, and a fan 26 is connected to one side of the dryer 25 through a pipe. One end of the air inlet pipe 401 outside the machine body 1 is sleeved with a telescopic hose 27, and the other end of the telescopic hose 27 is equipped with an exhaust hood 28. The telescopic hose 27, the air inlet pipe 401, and the exhaust hood 28 are all detachable connections. The specific operation is as follows: when the float plate 13 rises and drives the ring plate 406 to rotate, the ring plate 406 can push the top block 22 through the top plate 407, thereby causing the filter plate 21 to move in the ring groove 20, and causing the filter plate 21 to vibrate repeatedly under the action of the vibration spring 24, shaking off the impurities intercepted by the filter plate 21 and discharging them with the wastewater, thus preventing impurities from clogging the filter plate 21. When adding new absorbent liquid, the ring plate 406 can drive the filter plate 21 to vibrate the absorbent liquid again, thereby assisting in the mixing of the absorbent liquid.

[0024] In summary, when using this factory air purifier for electroplating, first fix the exhaust hood 28 to the electroplating tank, then connect the telescopic hose 27 to the exhaust hood 28 and the air inlet pipe 401, and provide the feed inlet 5 to add different absorbent liquids to the deacidification chamber 2 and the dealkaliification chamber 3 until the liquid level is flush with the feed inlet 5. Start the fan 26, and the fan 26 can draw the waste gas generated in the electroplating tank from the exhaust hood 28 through the telescopic hose 27 into the air inlet pipe 401; After the exhaust gas enters the deacidification chamber 2 through the inlet pipe 401, the absorbent liquid in the deacidification chamber 2 will absorb the dust and acidic substances mixed in the exhaust gas. After the deacidified exhaust gas floats away from the absorbent liquid, it can enter the dealkali chamber 3 through the flow pipe 402 to absorb the alkaline substances in the exhaust gas. After the exhaust gas is dried by the drying box, it is sent out of the machine body 1 by the fan 26 to other purification devices for other purification processes. When the absorbent liquid treats the waste gas, the dust or suspended matter in the absorbent liquid that enters with the waste gas may adhere to the inner wall of the inlet pipe 401 or the flow pipe 402. As the absorbent liquid absorbs the harmful substances in the waste gas, the density of the absorbent liquid will gradually increase. As the density of the absorbent liquid increases, the float 13 will gradually rise in the absorbent liquid. The slot 14 can restrict the float 13 to prevent the float 13 from tilting when it moves. As the float 13 rises, the toothed rod 16 will be carried by the float 13 and move in the top slot 7. At the same time, the plug 12 will also move in the connecting port 11 as the sealing plate 8 rises. When the toothed rod 16 moves, it will push the sealing plate 8 to slide in the sealing slot 6, gradually closing the feed port 5. When the absorbent liquid is close to absorption saturation, the plug 12 will disengage from the connecting port 11, opening the connecting port 11, allowing the nearly saturated absorbent liquid waste liquid to be discharged from the deacidification chamber 2 or the dealkali chamber 3 through the connecting port 11 into the waste liquid chamber 10 for subsequent treatment. During the upward movement of the rack 16, the rack 16 can drive the helical gear 18 to rotate in the rotating groove 15 via the transmission wheel 19. The empty groove 17 on the rack 16 prevents the helical gear 18 from colliding or contacting with the rack 16, thus avoiding the rack 16 from hindering the rotation of the helical gear 18. When the helical gear 18 rotates, it can drive the ring plate 406 to rotate in the ring groove 20 via the toothed groove 408 on the ring plate 406, and drive the rotating ring 403 to rotate at the bottom of the air inlet pipe 401 or the flow pipe 402 via the blade 405, causing the scraper 404 to move in the air inlet pipe 401 or the flow pipe 402. The spiral scraper 404 can move along the inner wall of the pipe and scrape off the impurities adhering to the inner wall of the pipe. The removed impurities can then enter the absorbent liquid along with the exhaust gas. The inclined blade 405 can push the impurities entering the absorbent liquid downwards, causing them to accumulate at the bottom of the absorbent liquid, so that the impurities can be discharged with the exhaust liquid as soon as possible, reducing residue. When the absorbent liquid treats the waste gas, the filter plate 21 can intercept impurities and suspended solids in the absorbent liquid and keep them below the filter plate 21 so that the impurities can be discharged with the waste liquid. When the ring plate 406 rotates, it can drive the top plate 407 to move synchronously, and push the filter plate 21 to move in the ring groove 20 through the top block 22. Under the action of the vibration spring 24, the filter plate 21 will vibrate repeatedly in the ring groove 20, thereby shaking off the impurities intercepted by the filter plate 21 and pushing them to the lower part of the absorbent liquid by the blade plate 405 so that they can be discharged with the wastewater, avoiding impurities clogging the filter plate 21. The limiting rod 23 can restrict the filter plate 21 to prevent the filter plate 21 from tilting during the movement. In the initial stage of waste liquid discharge, the float plate 13 will carry the plug 12 and float above the connection port 11. When the waste liquid level drops to the float plate 13, the float plate 13 will drop along with the liquid level, causing the plug 12 to close the connection port 11 and gradually open the feed port 5. The new absorbent liquid can then enter the deacidification chamber 2 or dealkali removal chamber 3 through the feed port 5 until the absorbent liquid level is flush with the feed port 5, thus completing the replacement of the absorbent liquid. When replacing the absorbent liquid, because the concentration of the absorbent liquid decreases, the float plate 13 will not pull the plug 12 out of the connection port 11, so that the absorbent liquid will remain in the deacidification chamber 2 or dealkali removal chamber 3. During the descent of the float plate 13, the gear rack 16 drives the transmission wheel 19 to rotate in the opposite direction, thereby causing the helical gear 18 to drive the ring plate 406 to rotate in the opposite direction through the tooth groove 408. This causes the blade plate 405 to agitate the absorbent liquid and push it upward, accelerating the mixing of the absorbent liquid. At the same time, the ring plate 406 can also drive the filter plate 21 to repeatedly vibrate in the ring groove 20, thereby agitating the absorbent liquid and assisting in the mixing of the absorbent liquid. This ensures that the concentration distribution of the absorbent liquid in the deacidification chamber 2 or the dealkali removal chamber 3 is uniform. After long-term use of the device, the telescopic hose 27 can be replaced and cleaned to prevent dust from accumulating inside the telescopic hose 27 and causing blockage.
