Description

Technical Field

[0001] This invention relates to the field of exhaust gas filtration technology, and in particular to an exhaust gas filtration device and method for PVC floor mat production equipment. Background Technology

[0002] PVC floor mats are widely used in homes, supermarkets, and offices due to their advantages such as good flexibility, slip resistance, wear resistance, and low cost. Market demand is high. However, during the production of PVC floor mats, the PVC resin is heated, generating a complex waste gas containing plasticizer oil mist, VOCs (volatile organic compounds), and trace amounts of hydrogen chloride. Direct emission of this complex waste gas would pollute the workshop environment and harm the health of on-site workers, while also causing air pollution and failing to meet current standards for pollutant emissions from the synthetic resin industry. Therefore, the waste gas must be filtered and purified.

[0003] Traditional waste gas treatment equipment typically reduces harmful components in waste gas through technologies such as filtration, adsorption, and catalysis. After the initial filtration stage, such as removing large particulate impurities through filter plates, the waste gas often needs further treatment, such as using activated carbon to adsorb volatile organic compounds (VOCs) in the waste gas, and then converting the harmful components in the waste gas through catalytic reactions.

[0004] However, when using filter plates, impurities gradually accumulate on their surface, especially when treating large amounts of waste gas. This accumulation of impurities hinders the smooth flow of gas, leading to a decrease in filtration efficiency. Furthermore, activated carbon and catalysts may experience reduced adsorption and conversion of harmful substances due to insufficient contact during long-term use. Activated carbon particles, due to their static accumulation, are prone to clogging in certain areas, resulting in impaired gas flow and reduced treatment efficiency. Summary of the Invention

[0005] This invention provides a waste gas filtration device and method for PVC floor mat production equipment. When filtering gas using a filter plate, the dust or impurities attached to the filter plate are dispersed. When using activated carbon to adsorb harmful substances in the gas, the contact between the gas and the activated carbon is more uniform and sufficient, improving the treatment effect of the catalyst and further enhancing the practicality of the filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste gas filtration device for PVC floor mat production equipment, the device comprising: Filter box; Multiple base plates are fixedly installed on the inner wall of the filter box, and a first sleeve rod is fixedly installed on one side of each of the multiple base plates; Multiple second sleeve rods are movably embedded in the inner walls of multiple first sleeve rods, and one end of each of the multiple second sleeve rods is fixedly provided with a mounting bracket. The mounting bracket can slide on the inner wall of the filter box. When the filter plate is pushed, the filter plate pushes the multiple second sleeve rods through the mounting bracket. The multiple second sleeve rods can slide on the inner walls of the multiple first sleeve rods respectively. A slide rail is fixedly installed at the bottom of the filter box, and a collection box is slidably installed on the inner wall of the slide rail. The collection box can slide on the inner wall of the slide rail.

[0007] As a further improvement of the present invention: both sides of the filter box are fixedly provided with flow guides, one of the flow guides is equipped with an exhaust gas inlet pipe, a handle is fixedly provided on one side of the collection box, a slot is opened on the side of the filter box near the collection box, the mounting frame is movably embedded in the inner wall of the filter box, a filter plate is fixedly provided on the inner wall of the mounting frame, and springs are movably sleeved on the outer surface of multiple second sleeve rods. The dispersed impurities fall into the interior of the collection box through the slot. The collection box can be removed by pulling the handle. At this time, the dust inside the collection box can be cleaned. When the multiple springs are squeezed, they will generate a reverse force. When the mounting frame is not impacted, the elastic force of the multiple springs pushes the mounting frame, and the filter plate moves back and forth.

[0008] As a further improvement of the present invention: an adsorption tank is fixedly installed on one side of another of the flow guide platforms, a cover plate is installed on one side of the adsorption tank, a fixing rod is fixedly installed on one side of the cover plate, an automatic telescopic rod is installed on the inner wall of the fixing rod, and a transmission rod is fixedly installed at the output end of the automatic telescopic rod. The transmission rod is movably embedded in the center of one side of the cover plate. When the switch of the automatic telescopic rod is turned on, the output shaft of the automatic telescopic rod is controlled to move back and forth. When the automatic telescopic rod moves back and forth, the fixing rod supports the automatic telescopic rod, so that the automatic telescopic rod is installed on the cover plate. The automatic telescopic rod can slide at the center of one side of the cover plate, and then the output shaft of the automatic telescopic rod drives the transmission rod to move back and forth, further causing the storage tank to move back and forth.

[0009] As a further improvement of the present invention: a storage tank is fixedly installed at one end of the transmission rod, the storage tank is movably embedded in the inner wall of the adsorption tank, multiple ventilation holes are opened on both sides of the storage tank, a first support rod is fixedly installed on the side of the storage tank near the filter box, activated carbon is placed inside the storage tank, and the waste gas is discharged into the storage tank through multiple ventilation holes on one side of the storage tank, and the volatile organic compounds in the waste gas are adsorbed by the activated carbon to remove harmful gases.

[0010] As a further improvement of the present invention: a first foam pad is fixedly provided on one side of the first support rod, and a second support rod is fixedly provided at the center of one side of the filter plate. A second foam pad is fixedly provided on one side of the second support rod. The first foam pad and the second foam pad are soft, which reduces the instantaneous impact force when impacted. When the storage tank moves back and forth, the storage tank drives the first support rod to move back and forth. The back and forth moving first support rod will drive the first foam pad to continuously impact the second foam pad, and further push the filter plate through the second support rod.

[0011] As a further improvement of the present invention: a catalytic tank is provided on the outer surface of the adsorption tank, a support plate is fixedly provided on the inner wall of the catalytic tank, a rotating rod is provided on the inner wall of the support plate through a bearing, and a gear is fixedly provided at one end of the rotating rod. After secondary treatment, the gas will be discharged into the interior of the catalytic tank. The catalytic tank contains a catalyst. The catalytic tank heats the internal catalyst to convert the harmful components in the waste gas into harmless gas. The support plate supports the rotating rod, and the rotating rod can rotate through the bearing.

[0012] As a further improvement of the present invention: a rack is meshed on the outer surface of the gear, and the rack is fixedly disposed on the outer surface of the transmission rod. When the transmission rod moves back and forth, it will drive the rack to move back and forth. The rack moving back and forth will drive the gear to rotate back and forth, which will further cause the rotating rod to rotate.

[0013] As a further improvement of the present invention: multiple stirring plates are fixedly arranged on the outer surface of the rotating rod, and a scraper is fixedly arranged on one side of each of the multiple stirring plates. The multiple scrapers are movably arranged on the inner wall of the catalytic tank. The rotating rod drives the multiple stirring plates to rotate, which in turn causes the multiple scrapers to rotate. The back-and-forth rotating stirring plates agitate the catalyst inside the catalytic tank, so that the catalyst and the exhaust gas come into full contact. When the multiple scrapers rotate back and forth, the multiple scrapers are in close contact with the inner wall of the catalytic tank. The back-and-forth rotating multiple scrapers will scrape the inner wall of the catalytic tank, preventing the catalyst from sticking to the inside of the catalytic tank when heated, thus affecting the gas catalytic effect.

[0014] As a further improvement of the present invention: a first conveying pipe is installed on one side of the catalytic tank, a fan is installed at one end of the first conveying pipe, and a second conveying pipe is fixedly installed at the output end of the fan. When the fan is turned on, the flow of gas is guided, and the treated gas is discharged through the first conveying pipe into the interior of the second conveying pipe, and the treated gas is further discharged.

[0015] A method for filtering exhaust gas from PVC floor mat production equipment includes the following steps: S1. Exhaust gas is discharged into the filter box through the exhaust gas inlet pipe and one of the guide platforms. When the exhaust gas passes through the filter plate, the filter plate initially removes large particulate matter in the exhaust gas. S2. The pre-filtered exhaust gas is discharged into the adsorption tank through another guide platform for further treatment. Activated carbon is placed inside the storage tank. The exhaust gas is discharged into the storage tank through multiple vents on one side of the storage tank, where the volatile organic compounds in the exhaust gas are adsorbed by the activated carbon. S3. Turn on the switch of the automatic telescopic rod to control the output shaft of the automatic telescopic rod to move back and forth, so that the storage tank moves back and forth. The back and forth movement of the storage tank drives the activated carbon inside to move, breaking up the dust or impurities attached to the filter plate, and at the same time driving the gear to rotate back and forth. S4. After secondary gas treatment, the gas will be discharged into the catalytic tank. The catalytic tank contains a catalyst. The catalytic tank heats the internal catalyst to convert the harmful components in the exhaust gas into harmless gas. S5. The rotating agitator stirs the catalyst inside the catalytic tank, ensuring that the catalyst and exhaust gas come into full contact. S6. Turn on the fan switch to guide the flow of gas, and discharge the treated gas through the first conveying pipe into the interior of the second conveying pipe to further discharge the treated gas.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In use, the first moving support rod causes the first foam pad to continuously impact the second foam pad, further pushing the filter plate via the second support rod. The mounting frame can slide on the inner wall of the filter box. When the filter plate is pushed, it pushes multiple second rods via the mounting frame. These second rods can slide on the inner wall of the first rods. At this time, the multiple second rods are pushed by the mounting frame, compressing multiple springs. When compressed, the springs generate a counterforce. When the mounting frame is not impacted, the elastic force of the springs pushes the mounting frame, further moving the filter plate back and forth, breaking up dust or impurities attached to the filter plate, preventing the filter plate surface from reducing filtration performance due to the accumulation of pollutants. The broken impurities fall into the collection box through the slot. The collection box can slide on the inner wall of the slide rail. The collection box can be removed by pulling the handle, allowing for cleaning of the dust inside the collection box. Thus, when using the filter plate to filter gas, the filtration effect can be improved.

[0017] 2. The waste gas, after preliminary filtration, is discharged into the adsorption tank via another guide platform for further treatment. Activated carbon is placed inside the storage tank. The waste gas is discharged into the storage tank through multiple vents on one side. The activated carbon adsorbs volatile organic compounds in the waste gas, removing harmful gases. At this point, the automatic telescopic rod is activated, controlling the output shaft of the automatic telescopic rod to move back and forth. During this movement, the fixed rod supports the automatic telescopic rod, allowing it to slide on the cover plate. The output shaft of the automatic telescopic rod drives the transmission rod to move back and forth, further causing the storage tank to move back and forth. This movement of the storage tank moves the activated carbon inside, resulting in more uniform and thorough contact between the gas and the activated carbon. Harmful substances in the gas are more efficiently adsorbed by the activated carbon, while preventing activated carbon particles from accumulating in certain areas due to prolonged stillness, thus preventing channel blockage caused by particle accumulation and maintaining smooth airflow. This further improves the gas filtration effect, resulting in better adsorption of harmful substances in the gas and enhancing the overall filtration efficiency.

[0018] 3. After secondary gas treatment, the gas is discharged into the catalytic tank. The catalytic tank contains a catalyst, which is heated to convert harmful components in the waste gas into harmless gases. The reciprocating movement of the transmission rod drives the rack to move back and forth, which in turn drives the gears to rotate, further rotating the rotating rod. A support plate supports the rotating rod, which rotates via bearings. This rotating rod then drives multiple stirring plates to rotate, further rotating multiple scrapers. The reciprocating stirring plates agitate the catalyst inside the catalytic tank, ensuring thorough contact between the catalyst and the waste gas. As the scrapers rotate, they adhere closely to the inner wall of the catalytic tank, preventing the catalyst from sticking to the inside during heating and affecting the catalytic effect. Turning on the blower guides the gas flow, discharging the treated gas through the first conveying pipe into the second conveying pipe for further discharge. This improves the catalyst's treatment effect and enhances the practicality of the filtration device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 9 As shown, the present invention provides an exhaust gas filtration device and method for PVC floor mat production equipment. The device includes: a filter box 1; multiple base plates 201 fixedly disposed on the inner wall of the filter box 1, and a first sleeve rod 202 fixedly disposed on one side of each of the multiple base plates 201; multiple second sleeve rods 203 movably embedded in the inner wall of the multiple first sleeve rods 202, and a mounting frame 204 fixedly disposed at one end of each of the multiple second sleeve rods 203, the mounting frame 204 being able to slide on the inner wall of the filter box 1. When the filter plate 206 is pushed, the filter plate 206 pushes the multiple second sleeve rods 203 through the mounting frame 204, and the multiple second sleeve rods 203 are respectively able to slide on the inner wall of the multiple first sleeve rods 202; a slide rail 207 fixedly disposed at the bottom of the filter box 1, and a collection box 208 slidably disposed on the inner wall of the slide rail 207, the collection box 208 being able to slide on the inner wall of the slide rail 207.

[0031] Please see Figures 1 to 9 In one embodiment, guide platforms 2 are fixedly installed on both sides of the filter box 1. An exhaust gas inlet pipe 210 is installed on one side of one of the guide platforms 2. A handle 209 is fixedly installed on one side of the collection box 208. A slot 211 is opened on the side of the filter box 1 near the collection box 208. The mounting frame 204 is movably embedded in the inner wall of the filter box 1. A filter plate 206 is fixedly installed on the inner wall of the mounting frame 204. Springs 205 are movably sleeved on the outer surface of multiple second sleeve rods 203. The dispersed impurities fall into the interior of the collection box 208 through the slot 211. The collection box 208 can be removed by pulling the handle 209. At this time, the dust inside the collection box 208 is cleaned. When the multiple springs 205 are squeezed, they will generate a reverse force. When the mounting frame 204 is not impacted, the elastic force of the multiple springs 205 pushes the mounting frame 204, and the filter plate 206 moves back and forth.

[0032] Please see Figures 1 to 9 In one embodiment, an adsorption tank 3 is fixedly installed on one side of another flow guide 2. A cover plate 301 is installed on one side of the adsorption tank 3. A fixing rod 302 is fixedly installed on one side of the cover plate 301. An automatic telescopic rod 303 is installed on the inner wall of the fixing rod 302. A transmission rod 304 is fixedly installed at the output end of the automatic telescopic rod 303. The transmission rod 304 is movably embedded in the center of one side of the cover plate 301. When the switch of the automatic telescopic rod 303 is turned on, the output shaft of the automatic telescopic rod 303 is controlled to move back and forth. When the automatic telescopic rod 303 moves back and forth, the fixing rod 302 supports the automatic telescopic rod 303, so that the automatic telescopic rod 303 is installed on the cover plate 301. The automatic telescopic rod 303 can slide at the center of one side of the cover plate 301. Then, the output shaft of the automatic telescopic rod 303 drives the transmission rod 304 to move back and forth, which further causes the storage tank 305 to move back and forth.

[0033] Please see Figures 1 to 9 In one embodiment, a storage tank 305 is fixedly installed at one end of the transmission rod 304. The storage tank 305 is movably embedded in the inner wall of the adsorption tank 3. Multiple ventilation holes are opened on both sides of the storage tank 305. A first support rod 307 is fixedly installed on the side of the storage tank 305 near the filter box 1. Activated carbon is placed inside the storage tank 305. The waste gas is discharged into the storage tank 305 through the multiple ventilation holes on one side of the storage tank 305. The volatile organic compounds in the waste gas are adsorbed by the activated carbon to remove harmful gases.

[0034] Please see Figures 1 to 9 In one embodiment, a first foam pad 308 is fixedly disposed on one side of the first support rod 307, and a second support rod 309 is fixedly disposed at the center of one side of the filter plate 206. A second foam pad 310 is fixedly disposed on one side of the second support rod 309. The first foam pad 308 and the second foam pad 310 are soft, which reduces the instantaneous impact force during impact. When the storage tank 305 moves back and forth, the storage tank 305 drives the first support rod 307 to move back and forth. The back-and-forth movement of the first support rod 307 will cause the first foam pad 308 to continuously impact the second foam pad 310, and further push the filter plate 206 through the second support rod 309.

[0035] Please see Figures 1 to 9 In one embodiment, a catalytic tank 4 is disposed on the outer surface of the adsorption tank 3. A support plate 401 is fixedly disposed on the inner wall of the catalytic tank 4. A rotating rod 402 is disposed on the inner wall of the support plate 401 through a bearing. A gear 405 is fixedly disposed at one end of the rotating rod 402. After secondary gas treatment, it will be discharged into the interior of the catalytic tank 4. The catalytic tank 4 contains a catalyst. The catalytic tank 4 heats the internal catalyst to convert the harmful components in the waste gas into harmless gas. The support plate 401 supports the rotating rod 402, and the rotating rod 402 can rotate through the bearing.

[0036] Please see Figures 1 to 9 In one embodiment, a rack 406 is meshed on the outer surface of the gear 405. The rack 406 is fixedly disposed on the outer surface of the transmission rod 304. When the transmission rod 304 moves back and forth, it will drive the rack 406 to move back and forth. The back and forth moving rack 406 drives the gear 405 to rotate back and forth, which further causes the rotating rod 402 to rotate.

[0037] Please see Figures 1 to 9In one embodiment, a plurality of stirring plates 403 are fixedly disposed on the outer surface of the rotating rod 402, and a scraper 404 is fixedly disposed on one side of each of the stirring plates 403. The scraper 404 is movably disposed on the inner wall of the catalytic tank 4. The rotating rod 402 drives the stirring plates 403 to rotate, which in turn causes the scraper 404 to rotate. The rotating stirring plates 403 agitate the catalyst inside the catalytic tank 4, so that the catalyst and the exhaust gas come into full contact. When the scraper 404 rotates back and forth, the scraper 404 is in close contact with the inner wall of the catalytic tank 4. The rotating scraper 404 scrapes the inner wall of the catalytic tank 4, preventing the catalyst from sticking to the inside of the catalytic tank 4 when heated, thus affecting the gas catalytic effect.

[0038] Please see Figures 1 to 9 In one embodiment, a first conveying pipe 407 is installed on one side of the catalytic tank 4. A blower 408 is installed at one end of the first conveying pipe 407. A second conveying pipe 409 is fixedly installed at the output end of the blower 408. When the blower 408 is turned on, the flow of gas is guided, and the treated gas is discharged through the first conveying pipe 407 into the interior of the second conveying pipe 409, and the treated gas is further discharged.

[0039] The working principle and usage process of this invention are as follows: When filtering industrial waste gas, waste gas is discharged into the filter box 1 through the waste gas inlet pipe 210 and one of the guide platforms 2. As the waste gas passes through the filter plate 206, the filter plate 206 initially removes large particulate matter such as dust and oil mist. The pre-filtered waste gas is then discharged into the adsorption tank 3 through another guide platform 2 for further processing. Activated carbon is placed inside the storage tank 305. The waste gas is discharged into the storage tank 305 through multiple vents on one side of the storage tank 305. The activated carbon adsorbs volatile organic compounds in the waste gas, removing harmful gases. At this time, the switch of the automatic telescopic rod 303 is turned on, controlling the output shaft of the automatic telescopic rod 303 to move back and forth. While the automatic telescopic rod 303 moves back and forth, the fixed rod 302... The automatic telescopic rod 303 provides support, allowing it to be mounted on the cover plate 301. The automatic telescopic rod 303 can slide at the center of one side of the cover plate 301. The output shaft of the automatic telescopic rod 303 drives the transmission rod 304 to move back and forth, further causing the storage tank 305 to move back and forth. The moving storage tank 305 moves the activated carbon inside, making the contact between the gas and the activated carbon more uniform and sufficient. Harmful substances in the gas are more efficiently adsorbed by the activated carbon, while preventing activated carbon particles from accumulating in certain areas due to long-term stillness, thus preventing channel blockage caused by particle accumulation, maintaining smooth airflow, and further improving the gas filtration effect. Therefore, when using activated carbon to adsorb harmful substances in the gas, the adsorption effect of activated carbon is better, improving the gas filtration effect. As the storage tank 305 moves back and forth, it drives the first support rod 307 to move back and forth as well. The reciprocating movement of the first support rod 307 causes the first foam pad 308 to continuously impact the second foam pad 310. This further pushes the filter plate 206 via the second support rod 309. The mounting bracket 204 can slide along the inner wall of the filter box 1. When the filter plate 206 is pushed, it pushes multiple second sleeve rods 203 via the mounting bracket 204. These second sleeve rods 203 can slide along the inner wall of multiple first sleeve rods 202. At this time, the multiple second sleeve rods 203, pushed by the mounting bracket 204, compress multiple springs 205. 5 When squeezed, a reverse force is generated. When the mounting frame 204 is not impacted, the elastic force of multiple springs 205 pushes the mounting frame 204, and the filter plate 206 moves back and forth, breaking up the dust or impurities attached to the filter plate 206, preventing the filter plate 206 from reducing its filtration performance due to the accumulation of pollutants. The broken impurities fall into the inside of the collection box 208 through the slot 211. The collection box 208 can slide on the inner wall of the slide rail 207. The collection box 208 can be removed by pulling the handle 209. At this time, the dust inside the collection box 208 is cleaned, thereby improving the filtration effect of the gas when using the filter plate 206 to filter the gas. After secondary gas treatment, the gas is discharged into the catalytic converter 4. The catalytic converter 4 contains a catalyst, which is heated to convert harmful components in the exhaust gas into harmless gases. When the drive rod 304 moves back and forth, it drives the rack 406 to move back and forth. The rack 406 drives the gear 405 to rotate, further causing the rotating rod 402 to rotate. The support plate 401 supports the rotating rod 402, and the rotating rod 402 can rotate via bearings. The rotating rod 402 then drives multiple agitator plates 403 to rotate, further causing multiple scraper plates 404 to rotate. The reciprocating agitator plates 403 stir the catalytic converter. The internal catalyst 4 ensures full contact between the catalyst and the exhaust gas. As multiple scrapers 404 rotate back and forth, they adhere tightly to the inner wall of the catalytic tank 4. The rotating scrapers 404 scrape the inner wall of the catalytic tank 4, preventing the catalyst from sticking to the inside of the catalytic tank 4 during heating and affecting the gas catalytic effect. Turning on the blower 408 guides the flow of gas, and the treated gas is discharged through the first conveying pipe 407 into the second conveying pipe 409 for further discharge of the treated gas. This improves the treatment effect of the catalyst and enhances the practicality of the filtration device.

10. A method for filtering exhaust gas from a PVC floor mat production equipment, characterized in that: A waste gas filtration device for PVC floor mat production equipment according to claims 1-9 includes the following steps: S1. Waste gas is discharged into the filter box (1) through the waste gas inlet pipe (210) and one of the guide platforms (2). When the waste gas passes through the filter plate (206), the filter plate (206) initially removes large particulate matter in the waste gas. S2. The pre-filtered waste gas is discharged into the adsorption tank (3) through another guide platform (2) for further treatment. Activated carbon is placed inside the storage tank (305). The waste gas is discharged into the storage tank (305) through multiple vent holes on one side of the storage tank (305). The volatile organic compounds in the waste gas are adsorbed by the activated carbon. S3. Turn on the switch of the automatic telescopic rod (303) to control the output shaft of the automatic telescopic rod (303) to move back and forth, so that the storage tank (305) moves back and forth. The back and forth movement of the storage tank (305) drives the activated carbon inside to move, breaking up the dust or impurities attached to the filter plate (206), and at the same time driving the gear (405) to rotate back and forth. S4. After secondary treatment, the gas will be discharged into the inside of the catalytic tank (4). The catalytic tank (4) contains a catalyst. The catalytic tank (4) heats the internal catalyst to convert the harmful components in the exhaust gas into harmless gas. S5. The rotating agitator (403) stirs the catalyst inside the catalytic tank (4), so that the catalyst and the exhaust gas come into full contact. S6. Turn on the fan (408) to guide the flow of gas, and discharge the treated gas through the first conveying pipe (407) into the interior of the second conveying pipe (409) to further discharge the treated gas.
