Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically an automatic waste gas treatment device for plastic production. Background Technology

[0002] Plastics are generally made from various chemical plastic raw materials such as polyethylene and polypropylene. During the production of plastic products, a large amount of harmful gases are generated. If these gases are directly emitted, they will cause environmental pollution. Therefore, the waste gases need to be purified before being emitted to reduce environmental pollution.

[0003] A patent with publication number CN120305799A discloses a waste gas treatment device for plastic production, including a support frame and a waste gas treatment box fixedly installed on the top outer surface of the support frame. An activated carbon purification box is detachably installed on the inner wall of the waste gas treatment box. A baffle is fixedly installed on the inner wall of the activated carbon purification box, and an air hole is formed at the top edge of the baffle. When waste gas passes through the air hole, it quickly passes through the activated carbon cylinder, where the high-efficiency activated carbon purifies the waste gas. After one activated carbon cylinder has worked for two hours, a motor rotates a rotating disc, and the activated carbon cylinder on one side edge of the air hole is replaced, allowing a new activated carbon cylinder to be reconnected to the outlet of the air hole.

[0004] However, in existing waste gas treatment equipment, during the extraction phase, a baffle with several holes on one side of the extraction box is used to draw in waste gas from the workshop. However, in long-term use, these holes gradually become obstacles to waste gas treatment. Because the workshop waste gas contains a large amount of particulate matter, these particles continuously adhere to the inner wall and surrounding area of ​​the baffle holes during continuous extraction. Over time, the particles accumulate and eventually clog the holes. This not only severely affects the extraction efficiency of the workshop waste gas, preventing it from smoothly entering the treatment equipment, but also causes a large amount of waste gas to accumulate in the workshop, making it impossible to treat effectively and promptly, posing a threat to the workshop environment and employee health.

[0005] Therefore, the present invention provides an automatic treatment device for waste gas from plastic production. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: An automatic waste gas treatment device for plastic production, comprising a housing, a positioning box fixedly connected to the upper surface of the housing, an air outlet on the upper surface of the positioning box, a first baffle fixedly connected to one side of the housing, a second baffle fixedly connected to one end of the first baffle, the first and second baffles being progressively arranged, and an air inlet between the first and second baffles, with a plurality of air inlet holes on the surfaces of the first and second baffles; a treatment component is provided inside the housing, the treatment component including a sliding plate slidably disposed inside the housing, a rotating roller rotatably connected to one end of the sliding plate, the rotating roller being used for treating the first baffle; a fixed frame is also fixedly connected inside the housing, an adsorption component is disposed within the fixed frame, the adsorption component being used for adsorbing particulate matter in the waste gas.

[0008] Preferably, the processing component further includes a first guide rail fixed inside the housing, the first guide rail having a first guide groove, a sliding block slidably connected in the first guide groove, and one side of the sliding block being fixedly connected to a sliding plate.

[0009] Preferably, the sliding plate has a positioning groove inside, and a top plate is slidably connected in the positioning groove. The top plate has a spindle-shaped cross-section.

[0010] Preferably, auxiliary grooves are provided on both sides of the inner wall of the positioning groove, auxiliary blocks are fixedly connected to both sides of the top plate, auxiliary springs are fixedly connected to both sides of the auxiliary blocks, and the two auxiliary springs are fixedly connected to the inner wall of the auxiliary groove.

[0011] Preferably, the fixed frame has several connecting grooves inside, and a connecting spring is fixed to the inner wall of the connecting groove. One end of the connecting spring is fixed to a protrusion, and the protrusions abut against the top plate one by one.

[0012] Preferably, the fixed frame has several fixed slots inside, and two rotating shafts are rotatably connected inside each fixed slot. Both ends of each rotating shaft are provided with torsion springs, and several vibrating plates are fixed to the circumferential surface of each rotating shaft. The vibrating plates are made of activated carbon.

[0013] Preferably, a spray plate is fixedly connected to one side of the fixed frame, a pressure sensor is fixedly connected to one side of the spray plate, and the sliding plate can abut against the pressure sensor.

[0014] Preferably, during the exhaust gas treatment process, the suction pump inside the positioning box is first started. After the suction pump starts, the exhaust gas in the workshop is drawn into the box along the first and second baffles on one side of the box. During the suction process, the exhaust gas in the workshop is guided into the box by the first and second guide plates. During the guidance process, the exhaust gas is restricted by the progressive first and second baffles, so that the exhaust gas directly impacts the first and second baffles, reducing the adhesion of particulate matter. After the exhaust gas treatment equipment is used, the first guide rail inside the box is started, and the sliding block inside the first guide rail slides. The sliding block drives the sliding plate fixed to it, and the sliding plate drives the rotating roller at its end to slide along the first baffle. The brush on the surface of the rotating roller will clean the holes on the surface of the first baffle. In addition, an adsorption component is also installed inside the box. The air drawn into the box is adsorbed by the adsorption component to remove particulate matter from the gas.

[0015] Preferably, during the sliding process of the sliding plate, the top plate inside the sliding plate will press against the protrusion inside the fixed frame. When the top plate is directly facing the protrusion, the protrusion presses against the top plate under the restoring force of the connecting spring. The top plate slides along the positioning groove inside the sliding plate, so that the other end of the top plate slides out of the positioning groove. The other end of the top plate abuts against the rotating roller, cleaning the brush on the surface of the rotating roller and removing the particles adhering between the brushes. The cleaned particles fall from the air inlet on the surface of the first baffle.

[0016] Preferably, during the air extraction process, the exhaust gas entering the chamber passes through several fixed slots on the surface of the fixed frame. The vibrating plates installed inside the fixed slots vibrate under the drive of the built-in motor inside the fixed frame. The built-in motor drives the rotating shaft to rotate back and forth, causing several vibrating plates on the circumference of the rotating shaft to vibrate, thus enabling the vibrating plates to adsorb particulate matter. In addition, during the movement of the sliding plate, when the sliding plate moves to the top of the fixed frame, the sliding plate comes into contact with the pressure sensor on the surface of the spray plate on one side of the fixed frame, thereby triggering the spray plate. The spray plate sprays cleaning liquid onto the surface of the rotating roller to assist the rotating roller in cleaning.

[0017] The beneficial effects of this invention are as follows: 1. The automatic waste gas treatment device for plastic production as described in this invention, by activating the air pump inside the positioning box, guides the workshop waste gas into the box using a first baffle and a second baffle. The progressive baffles limit the waste gas from impacting the baffles, effectively reducing particulate matter adhesion and easing the burden on subsequent treatment. After use, the sliding plate and rotating roller are driven by the first guide rail and sliding block. The brush on the rotating roller automatically cleans the holes on the surface of the first baffle, preventing blockage and ensuring smooth waste gas extraction, thus improving treatment efficiency. Simultaneously, the adsorption components installed inside the box adsorb particulate matter entering the box, deeply purifying the waste gas, reducing environmental pollution, protecting employee health, and achieving efficient and environmentally friendly waste gas treatment.

[0018] 2. The automatic waste gas treatment device for plastic production of the present invention, when the sliding plate slides, the top plate is pressed against the protrusion in the fixed frame. The top plate first presses against the protrusion, and then under the action of the resetting force of the connecting spring, the protrusion presses against the top plate again, so that the top plate slides along the positioning groove and extends out to abut against the rotating roller. This process can automatically clean the brush on the surface of the rotating roller, remove the particles adhering between the brushes in time, ensure that the brush always maintains good cleaning ability, and thus ensure the cleaning effect of the hole of the first baffle. The cleaned particles fall from the air inlet, avoiding accumulation inside the equipment, maintaining the cleanliness of the inside of the equipment, and extending the service life of the equipment.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 7As shown in the embodiment of the present invention, an automatic waste gas treatment device for plastic production includes a positioning box 13 fixedly connected to the upper surface of a housing 1. An air outlet 14 is provided on the upper surface of the positioning box 13. A first baffle 11 is fixedly connected to one side of the housing 1, and a second baffle 12 is fixedly connected to one end of the first baffle 11. The first baffle 11 and the second baffle 12 are arranged in a progressive manner, and an air inlet is provided between the first baffle 11 and the second baffle 12. A plurality of air inlet holes are provided on the surfaces of the first baffle 11 and the second baffle 12. A treatment assembly is provided inside the housing 1. The processing component includes a sliding plate 32 slidably disposed inside the housing 1, with a rotating roller 34 rotatably connected to one end of the sliding plate 32. The rotating roller 34 is used for processing the first baffle 11. A fixed frame 2 is also fixedly connected inside the housing 1, and an adsorption component is disposed inside the fixed frame 2. The adsorption component is used to adsorb particulate matter in the exhaust gas. The processing component also includes a first guide rail 3 fixedly connected inside the housing 1. A first guide groove 31 is opened in the first guide rail 3, and a sliding block 33 is slidably connected in the first guide groove 31. One side of the sliding block 33 is fixedly connected to the sliding plate 32.

[0023] Specifically, in the existing waste gas treatment equipment, during the extraction phase, a baffle with several holes on one side of the extraction box is used to draw in waste gas from the workshop. However, in long-term use, these holes gradually become obstacles to waste gas treatment. Because the workshop waste gas contains a large amount of particulate matter, these particles continuously adhere to the inner wall and surrounding area of ​​the baffle holes during continuous extraction. Over time, the particles accumulate and eventually clog the holes. This not only severely affects the extraction efficiency of the workshop waste gas, preventing it from smoothly entering the treatment equipment, but also causes a large amount of waste gas to accumulate in the workshop, making it impossible to treat effectively and in a timely manner, posing a threat to the workshop environment and employee health. Therefore, the present invention addresses the aforementioned problems by providing the above-mentioned structure. First, during the waste gas treatment process, the suction pump inside the positioning box 13 is activated. After the suction pump is activated, the waste gas in the workshop is drawn into the box 1 along the first baffle 11 and the second baffle 12 on one side of the box 1. During the suction process, the waste gas in the workshop is guided into the box 1 by the first guide plate and the second guide plate. During the guidance process, the waste gas is restricted by the progressive first baffle 11 and the second baffle 12, causing the waste gas to directly collide with the first baffle 11 and the second baffle 12. 2. Reduce particulate matter adhesion. After the exhaust gas treatment equipment is used, the first guide rail 3 inside the housing 1 is activated. The sliding block 33 inside the first guide rail 3 slides, and the sliding block 33 drives the sliding plate 32 fixed to it. The sliding plate 32 drives the rotating roller 34 at its end to slide along the first baffle 11. The brush on the surface of the rotating roller 34 will clean the holes on the surface of the first baffle 11. In addition, an adsorption component is also installed inside the housing 1. The air drawn into the housing 1 is adsorbed by the adsorption component to adsorb particulate matter in the gas. By activating the air pump inside the positioning box 13, and with the help of the first baffle 11 and the second baffle 12, the workshop exhaust gas can be guided into the box 1. The progressive baffles limit the exhaust gas from impacting the baffles, effectively reducing particulate matter adhesion and easing the burden on subsequent treatment. After use, the first guide rail 3 and the sliding block 33 drive the sliding plate 32 and the rotating roller 34. The brush on the rotating roller 34 can automatically clean the holes on the surface of the first baffle 11, preventing the holes from becoming clogged, ensuring smooth exhaust gas extraction, and improving treatment efficiency. At the same time, the adsorption components installed inside the box 1 can adsorb particulate matter in the air entering the box 1, deeply purifying the exhaust gas, reducing the pollution of the exhaust gas to the environment, protecting the health of employees, and achieving efficient and environmentally friendly exhaust gas treatment.

[0024] Example 2: Figures 1 to 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a positioning groove 36 is provided inside the sliding plate 32, and a top plate 39 is slidably connected inside the positioning groove 36. The cross-section of the top plate 39 is spindle-shaped. Auxiliary grooves 35 are provided on both sides of the inner wall of the positioning groove 36. Auxiliary blocks 37 are fixedly connected to both sides of the top plate 39. Auxiliary springs 38 are fixedly connected to both sides of the auxiliary blocks 37. The two auxiliary springs 38 are fixedly connected to the inner wall of the auxiliary groove 35. A plurality of connecting grooves 26 are provided inside the fixed frame 2. Connecting springs 27 are fixedly connected to the inner wall of the connecting grooves 26. A protrusion 28 is fixedly connected to one end of the connecting spring 27. The protrusions 28 abut against the top plate 39 one by one.

[0025] Specifically, during the sliding process of the sliding plate 32, the top plate 39 inside the sliding plate 32 will press against the protrusion 28 inside the fixed frame 2. The top plate 39 presses against the protrusion 28. When the top plate 39 is directly facing the protrusion 28, the protrusion 28 presses against the top plate 39 under the restoring force of the connecting spring 27. The top plate 39 slides along the positioning groove 36 inside the sliding plate 32, so that the other end of the top plate 39 slides out of the positioning groove 36. The other end of the top plate 39 abuts against the rotating roller 34, cleaning the brush on the surface of the rotating roller 34 and cleaning the particles adhering between the brushes. The cleaned particles fall from the air inlet on the surface of the first baffle 11. As the sliding plate 32 slides, the top plate 39 presses against the protrusion 28 inside the fixed frame 2. The top plate 39 first presses against the protrusion 28, and then, under the restoring force of the connecting spring 27, the protrusion 28 presses against the top plate 39 again, causing the top plate 39 to slide along the positioning groove 36 and extend out to abut against the rotating roller 34. This process can automatically clean the brush on the surface of the rotating roller 34, remove particles adhering between the brushes in time, and ensure that the brush always maintains good cleaning ability, thereby ensuring the cleaning effect on the holes of the first baffle 11. The cleaned particles fall from the air inlet, avoiding accumulation inside the equipment, maintaining the cleanliness inside the equipment, and extending the service life of the equipment.

[0026] like Figure 7As shown, the fixed frame 2 in this embodiment has several fixed slots 23 inside, and two rotating shafts 24 are rotatably connected inside each fixed slot 23. Both ends of the rotating shafts 24 are provided with torsion springs. Several vibrating plates 25 are fixed to the circumferential surface of each rotating shaft 24. The vibrating plates 25 are made of activated carbon. A spray plate 22 is fixed to one side of the fixed frame 2, and a pressure sensor 21 is fixed to one side of the spray plate 22. The sliding plate 32 can abut against the pressure sensor 21.

[0027] Specifically, during the air extraction process, the exhaust gas entering the housing 1 passes through several fixed slots 23 on the surface of the fixed frame 2. The vibrating plates 25 installed inside the fixed slots 23 vibrate under the drive of the built-in motor inside the fixed frame 2. The built-in motor drives the rotating shaft 24 to rotate back and forth, causing several vibrating plates 25 on the circumference of the rotating shaft 24 to vibrate, so that the vibrating plates 25 perform particulate matter adsorption. In addition, during the movement of the sliding plate 32, when the sliding plate 32 moves to the top of the fixed frame 2, the sliding plate 32 comes into contact with the pressure sensor 21 on the surface of the spray plate 22 on one side of the fixed frame 2, thereby triggering the spray plate 22. The spray plate 22 sprays cleaning liquid onto the surface of the rotating roller 34 to assist the rotating roller 34 in cleaning. During the extraction process, the exhaust gas enters the housing 1 through the fixing groove 23 of the fixed frame 2. The built-in motor drives the rotating shaft 24, which in turn causes the vibrating plate 25 to vibrate. This vibration can adsorb particulate matter in the exhaust gas, enhancing the purification effect and reducing the burden of subsequent treatment. When the sliding plate 32 moves to the top of the fixed frame 2 and comes into contact with the spray plate 22 at the pressure sensor 21, the spray plate 22 sprays cleaning liquid onto the surface of the rotating roller 34. When the rotating roller 34 cleans the holes of the first baffle 11, the cleaning liquid can help dissolve and wash away the stubborn particles adhering to the brush, further improving the cleaning effect. The two work together to ensure the efficient operation of the exhaust gas treatment equipment, extend the service life of the key components of the equipment, and reduce maintenance costs.

[0028] Working principle: First, when performing waste gas treatment, the air pump inside the positioning box 13 is started. After the air pump is started, the waste gas in the workshop is drawn into the box 1 along the first baffle 11 and the second baffle 12 on one side of the box 1. During the air extraction process, the waste gas in the workshop is guided into the box 1 by the first guide plate and the second guide plate. During the guidance process, the waste gas is restricted by the progressive first baffle 11 and the second baffle 12, so that the waste gas directly impacts the first baffle 11 and the second baffle 12, reducing the adhesion of particulate matter. After the waste gas treatment equipment is used, the first guide rail 3 inside the box 1 is started. The sliding block 33 inside the first guide rail 3 slides. The sliding block 33 drives the sliding plate 32 fixed to it. The sliding plate 32 drives the rotating roller 34 at its end to slide along the first baffle 11. The brush on the surface of the rotating roller 34 will clean the holes on the surface of the first baffle 11. In addition, an adsorption component is also set inside the box 1. The air drawn into the box 1 is adsorbed by the adsorption component to remove particulate matter from the gas. By activating the air pump inside the positioning box 13, and with the help of the first baffle 11 and the second baffle 12, the workshop exhaust gas can be guided into the box 1. The progressive baffles limit the exhaust gas from impacting the baffles, effectively reducing particulate matter adhesion and reducing the burden on subsequent treatment. After use, the sliding plate 32 and the rotating roller 34 are driven by the first guide rail 3 and the sliding block 33. The brush on the rotating roller 34 can automatically clean the holes on the surface of the first baffle 11, preventing the holes from becoming blocked, ensuring smooth exhaust gas extraction, and improving treatment efficiency. At the same time, the adsorption components installed inside the box 1 can adsorb particulate matter in the air entering the box 1, deeply purifying the exhaust gas, reducing the pollution of the exhaust gas to the environment, protecting the health of employees, and achieving efficient and environmentally friendly exhaust gas treatment. Additionally, during the sliding process of the sliding plate 32, the top plate 39 inside the sliding plate 32 will press against the protrusion 28 inside the fixed frame 2. The top plate 39 presses against the protrusion 28. When the top plate 39 is directly facing the protrusion 28, the protrusion 28 presses against the top plate 39 under the restoring force of the connecting spring 27. The top plate 39 slides along the positioning groove 36 inside the sliding plate 32, so that the other end of the top plate 39 slides out of the positioning groove 36. The other end of the top plate 39 abuts against the rotating roller 34, cleaning the brush on the surface of the rotating roller 34 and cleaning the particles adhering between the brushes. The cleaned particles fall from the air inlet on the surface of the first baffle 11. As the sliding plate 32 slides, the top plate 39 presses against the protrusion 28 inside the fixed frame 2. The top plate 39 first presses against the protrusion 28, and then, under the restoring force of the connecting spring 27, the protrusion 28 presses against the top plate 39 again, causing the top plate 39 to slide along the positioning groove 36 and extend out to abut against the rotating roller 34. This process can automatically clean the brush on the surface of the rotating roller 34, remove the particles adhering between the brushes in time, and ensure that the brush always maintains good cleaning ability, thereby ensuring the cleaning effect on the holes of the first baffle 11. The cleaned particles fall from the air inlet, avoiding accumulation inside the equipment, maintaining the cleanliness inside the equipment, and extending the service life of the equipment. Furthermore, during the air extraction process, the exhaust gas entering the housing 1 passes through several fixed slots 23 on the surface of the fixed frame 2. The vibrating plates 25 installed inside the fixed slots 23 will vibrate under the drive of the built-in motor inside the fixed frame 2. The built-in motor drives the rotating shaft 24 to rotate back and forth, causing several vibrating plates 25 on the circumference of the rotating shaft 24 to vibrate, so that the vibrating plates 25 can perform particulate matter adsorption. In addition, during the movement of the sliding plate 32, when the sliding plate 32 moves to the top of the fixed frame 2, the sliding plate 32 comes into contact with the pressure sensor 21 on the surface of the spray plate 22 on one side of the fixed frame 2, thereby triggering the spray plate 22. The spray plate 22 sprays cleaning liquid onto the surface of the rotating roller 34 to assist the rotating roller 34 in cleaning. During the extraction process, the exhaust gas enters the housing 1 through the fixing groove 23 of the fixed frame 2. The built-in motor drives the rotating shaft 24, which in turn causes the vibrating plate 25 to vibrate. This vibration can adsorb particulate matter in the exhaust gas, enhancing the purification effect and reducing the burden of subsequent treatment. When the sliding plate 32 moves to the top of the fixed frame 2 and comes into contact with the spray plate 22 at the pressure sensor 21, the spray plate 22 sprays cleaning liquid onto the surface of the rotating roller 34. When the rotating roller 34 cleans the holes of the first baffle 11, the cleaning liquid can help dissolve and wash away the stubborn particles adhering to the brush, further improving the cleaning effect. The two work together to ensure the efficient operation of the exhaust gas treatment equipment, extend the service life of the key components of the equipment, and reduce maintenance costs.

The cleaned particles fall from the air inlet on the surface of the first baffle (11).

10. An automatic treatment device for waste gas from plastic production according to claim 7, characterized in that: During the air extraction process, the exhaust gas entering the housing (1) passes through several fixed slots (23) on the surface of the fixed frame (2). The vibrating plate (25) set inside the fixed slot (23) will vibrate under the drive of the built-in motor inside the fixed frame (2). The built-in motor drives the rotating shaft (24) to rotate back and forth, causing several vibrating plates (25) on the circumference of the rotating shaft (24) to vibrate, so that the vibrating plate (25) performs particulate adsorption. In addition, during the movement of the sliding plate (32), when the sliding plate (32) moves to the top of the fixed frame (2), the sliding plate (32) comes into contact with the pressure sensor (21) on the surface of the spray plate (22) on one side of the fixed frame (2), thereby triggering the spray plate (22). The spray plate (22) sprays cleaning liquid onto the surface of the rotating roller (34) to assist the rotating roller (34) in cleaning.
