Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a waste gas purification equipment for the production of automotive sealing strips. Background Technology

[0002] The automobile manufacturing process is complex due to the large number and precision of its internal parts. As one of these components, automotive sealing strips generate a significant amount of harmful exhaust gases during production. To prevent pollution or safety accidents caused by these gases, specialized exhaust gas purification equipment is required. To this end, the patent specification with publication number CN110694404A discloses an exhaust gas purification device for automotive sealing strips. The device includes a gas collection hood installed at the exhaust gas generation station, connected sequentially by pipelines; a suction filter for reducing the concentration of oil fumes and grease in the exhaust gas; an electrostatic oil fume purifier for removing oil fumes and grease from the exhaust gas; a composite photocatalytic device for removing some easily decomposed and oxidized components from the exhaust gas; an odor control box for removing volatile molecules from the exhaust gas; a centrifugal fan for drawing in exhaust gas; and a chimney for exhaust gas emission. This invention concentrates the exhaust gas generated during the manufacture of automotive sealing strips through the gas collection hood. Under the action of the centrifugal fan, the exhaust gas sequentially enters the suction filter, electrostatic oil fume purifier, composite photocatalytic device, and odor control box through pipelines for treatment. Finally, it is discharged through the chimney, effectively removing organic matter and malodorous components from the exhaust gas, achieving purification of particulate matter and oily substances, thereby effectively improving the exhaust gas purification effect. The exhaust gas purification equipment for the aforementioned automotive sealing strips has a good purification effect during use, but some problems still exist: When the exhaust gas purification equipment for the aforementioned automotive sealing strips is in use, the exhaust gas contains a large amount of particulate matter, dirt, and harmful gases. Over time, the internal filter cloth and filter layer are prone to blockage and uneven airflow, which leads to a gradual decrease in filtration and purification effect. Frequent replacement of filter cloth and filter layer liquid will affect the production output of sealing strips. Summary of the Invention

[0003] The purpose of this invention is to provide an exhaust gas purification equipment for the production of automotive sealing strips, in order to solve the shortcomings of existing exhaust gas purification equipment with limited purification time.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a waste gas purification device for automotive sealing strip production, comprising a gas collection hood and a filter box.

[0007] Preferably, the first fixing frame and the slide rail are both in a sliding structure with the slider, and the first fixing frame is symmetrically distributed at both ends of the gas collection hood.

[0008] Preferably, the second fixing frame and the bidirectional screw are in a rotating structure, and the bidirectional screw and the internal threaded block are in a threaded connection structure.

[0009] Preferably, the bidirectional screw and the internal threaded block are connected by a thread, and the bottom end of the slider and the top end of the scissor holder are hinged.

[0010] Preferably, a cam is fixedly connected to the outer wall of the transmission rod, and a striking seat is rotatably connected to the bottom end of the cam. A shaft is fixedly connected to both ends of the striking seat, one end of which extends through to the outside of the cam and is wrapped with a torsion spring. A guide air plate is flipped and connected to the bottom end of the second support seat. Hinge rods are hinged to the top of both sides of the guide air plate. A main air plate is flipped and connected to one end of the second support seat. A hinged push rod is hinged to the top of the main air plate. A hinge seat is hinged to one end of the hinged push rod. A push-pull seat is fixedly connected to one end of the hinge seat. A side frame is sleeved on the outside of the push-pull seat. Guide rods are fixedly connected to both ends of the side frame. An internally threaded push plate is sleeved on the outside of the guide rod. One end of the push-pull seat is fixedly connected to one end of the internally threaded push plate. A reciprocating lead screw runs through the interior of the filter box. One end of the reciprocating lead screw extends to the outside of the side frame and is fixedly connected to one end of a connecting rod. The other end of the connecting rod is fixedly connected to a first conical tooth. A cover plate is rotatably connected to the bottom of the first support base. A drive gear sleeve is fixedly connected to the bottom of the cover plate. A drive gear is meshed with the bottom of the drive gear sleeve. One end of the transmission rod extends to the outside of the filter box and is fixedly connected to one end of a pulley assembly. A second conical tooth is fixedly connected to the other end of the pulley assembly. A side frame is fixedly connected to one end of the filter box. A drive rod is rotatably connected to both ends inside the side frame. A drive conical tooth is fixedly connected to the outer wall of the drive rod. The top end of the drive rod extends to the top end of the side frame and is fixedly connected to the bottom end of the motor assembly. One end of the drive gear is fixedly connected to one end of a third conical tooth.

[0011] Preferably, the transmission rod has a rotating structure with both ends inside the filter box, the cam has a hinged structure with the tapping seat, and the drive gear has a rotating structure with the outer wall of the filter box, so as to make the cam rotate smoothly.

[0012] Preferably, the internal threaded push plate and the reciprocating lead screw are connected by a thread, and the guide rod and the internal threaded push plate are connected by a sliding structure, so that the guide air plate can swing smoothly.

[0013] Preferably, a plurality of driving bevel teeth are fixed on the outer side of the driving rod, and the plurality of driving bevel teeth are respectively engaged with the first bevel tooth, the second bevel tooth and the third bevel tooth, so as to enable the components to operate in conjunction.

[0014] Compared with the prior art, the beneficial effects of the present invention are: by using a motor assembly to drive a number of drive bevel teeth to drive the cam, drive gear and guide air plate, thereby causing the cam, guide air plate and baffle to rotate and beat, guide the flow of exhaust gas and rotate and distribute the purification area, thereby extending the service life of the exhaust gas purification equipment. At the same time, by using a motor drive, the corrugated plastic cloth can be extended in height according to the exhaust gas emission position of the sealing strip production equipment. 1. When the first conical tooth is driven, the internal threaded push plate pushes and pulls the push-pull seat, thereby causing the hinged push rod to push and pull the top of the main air plate, and causing several auxiliary air plates to swing back and forth, so that the exhaust gas flowing through the second support seat can be evenly filtered through the filter cloth under the guidance of the auxiliary air plates and the main air plate, thereby prolonging the time when the filter cloth is blocked. Meanwhile, when the second conical tooth is driven, several pulley assemblies are driven to make the transmission rod drive the cam to rotate at a constant speed. During the rotation, the tapping seat continuously taps the top of the filter cloth, thereby knocking off the particulate impurities adsorbed at the bottom of the filter cloth.

[0015] Furthermore, when the third conical tooth is driven, the drive gear drives the baffle to rotate at a low speed through meshing with the drive gear sleeve. Since the baffle is perforated at intervals, the filter media assembly is used in different areas, making the adsorption and filtration distribution of the filter media assembly more uniform.

[0016] 2. A double-ended screw driven by a motor, along with the linkage between the transmission helical gear and the transmission helical gear seat, causes two sets of internal threaded blocks to push and pull the scissor frame. This, in turn, causes the second fixed frame to raise and lower the bottom of the corrugated plastic sheet, thereby controlling the height of the corrugated plastic sheet and allowing the gas collection hood to be adjusted to a certain extent according to the location of the exhaust gas emission point. Meanwhile, the corrugated plastic sheet is corrugated and wrinkled, and the concave part is fixed by a frame-shaped metal wire, so that the corrugated plastic sheet remains flat and unfolded when the second fixed frame is raised and lowered, so that the gas collection hood occupies as little space as possible and is easy to use.

[0020] Please see Figures 1-12This invention provides an exhaust gas purification device for automotive sealing strip production, comprising a gas collection hood 1 and a filter box 3. A gas supply pipe 2 is fixedly connected to the top of the gas collection hood 1, and a filter box 3 is fixedly connected to one end of the gas supply pipe 2. A combustion furnace 4 is arranged on one side of the filter box 3, and an exhaust tower 5 is arranged on one side of the combustion furnace 4. A first support base 8 is fixedly connected to the upper part of the filter box 3, and a filter media assembly 9 is installed inside the first support base 8. A second support base 10 is fixedly connected to the lower part of the filter box 3, and the top of the second support base 10... A filter cloth 11 is installed, and a centrifugal fan assembly 6 is installed at the bottom of one side of the exhaust tower 5. An adjustment structure 7 is fixedly connected to the bottom of the gas collection hood 1. The adjustment structure 7 includes a corrugated plastic sheet 701, a first fixing frame 702, a slide rail 703, a slider 704, a second fixing frame 705, a bidirectional screw 706, an internal thread block 707, a transmission helical gear 708, a transmission helical gear seat 709, and a scissor frame 710. The corrugated plastic sheet 701 is fixedly connected to the bottom of the gas collection hood 1, and the first fixing frame 702 is fixedly connected to both sides of the gas collection hood 1. At one end, a slide rail 703 is fixedly connected to the inner side of the first fixed frame 702. Slider blocks 704 are fitted on both sides of the outer wall of the slide rail 703. A second fixed frame 705 is fixedly connected to the bottom end of the corrugated plastic sheet 701. A bidirectional screw 706 is rotatably connected to the inner side of the second fixed frame 705. Internal threaded blocks 707 are fitted on both sides of the outer wall of the bidirectional screw 706. A transmission helical gear 708 is provided at the bottom of one side of the corrugated plastic sheet 701. One side of the bidirectional screw 706 extends through to one side of the second fixed frame 705 and is connected to the transmission helical gear 708. One side of the toothed seat 709 is fixedly connected, and the top of the scissor frame 710 is hinged to the scissor frame 710. The first fixed frame 702 and the slide rail 703 are both in a sliding structure with the slider 704. The first fixed frame 702 is symmetrically distributed at both ends of the gas collection hood 1. The second fixed frame 705 is in a rotating structure with the bidirectional screw 706. The bidirectional screw 706 is in a threaded connection structure with the internal thread block 707. The bottom end of the slider 704 is hinged to the top end of the scissor frame 710.

[0021] See attached document Figure 1 , Figure 2 and Figure 3When using this equipment, the bottom of the gas collection hood 1 should be close to the exhaust outlet of the automotive sealing strip production equipment so that the exhaust gas can enter the equipment for purification under the traction of the fan. To avoid excessive exhaust gas leakage due to a large distance between the gas collection hood 1 and the exhaust outlet, a corrugated plastic sheet 701 is fixed to the bottom of the gas collection hood 1. The motor drives the bidirectional screw 706, and through the linkage of the transmission helical gear 708 and the transmission helical gear seat 709, the two sets of internal threaded blocks 707 push and pull the scissor frame 710. This causes the second fixing frame 705 to drive the bottom of the corrugated plastic sheet 701 to rise and fall, thereby controlling the height of the corrugated plastic sheet 701. The height of the gas collection hood 1 can be adjusted to a certain extent according to the position of the exhaust outlet. The corrugated plastic sheet 701 is corrugated and wrinkled, and the concave part is fixed by a frame-shaped metal wire. This keeps the corrugated plastic sheet 701 flat and unfolded when the second fixing frame 705 rises and falls, so that the gas collection hood 1 occupies as little space as possible and is easy to use.

[0022] An auxiliary mechanism 12 is fixedly connected to one end of the filter box 3. The auxiliary mechanism 12 includes a transmission rod 1201, a cam 1202, a beater seat 1203, a shaft 1204, a torsion spring 1205, a guide air plate 1206, a hinge rod 1207, a main air plate 1208, a hinge push rod 1209, a hinge seat 1210, a push-pull seat 1211, a side frame 1212, a guide rod 1213, an internal thread push plate 1214, a reciprocating screw 1215, a connecting rod 1216, a first conical tooth 1217, a baffle plate 1218, a drive gear sleeve 1219, a drive gear 1220, a pulley assembly 1221, a second conical tooth 1222, a side frame 1223, a drive rod 1224, a drive conical tooth 1225, a motor assembly 1226, and a second conical tooth 1222.

The bottom end of the second support seat 10 is flipped to connect to the auxiliary air plate 1206. The top of both sides of the auxiliary air plate 1206 is hinged to the hinge rod 1207. One end of the second support seat 10 is flipped to connect to the main air plate 1208. The top of the main air plate 1208 is hinged to the hinge push rod 1209. One end of the first support 9 is hinged to a hinge seat 1210. A push-pull seat 1211 is fixedly connected to one end of the hinge seat 1210. A side frame 1212 is fitted onto the outer side of the push-pull seat 1211. Guide rods 1213 are fixedly connected to both ends inside the side frame 1212. An internally threaded push plate 1214 is fitted onto the outer side of the guide rods 1213. One end of the push-pull seat 1211 is fixedly connected to one end of the internally threaded push plate 1214. A reciprocating screw 1215 passes through the interior of the internally threaded push plate 1214. One end of the reciprocating screw 1215 passes through the outer side of the side frame 1212 and is fixedly connected to one end of a connecting rod 1216. The other end of the connecting rod 1216 is fixedly connected to a first conical tooth 1217. A cover plate 1218 is rotatably connected to the bottom end of the first support 8. A drive gear sleeve 1219 is fixedly connected to the bottom of component 18. A drive gear 1220 is meshed with the bottom of the drive gear sleeve 1219. One end of the transmission rod 1201 extends to the outside of the filter box 3 and is fixedly connected to one end of the pulley assembly 1221. A second conical tooth 1222 is fixedly connected to the other end of the pulley assembly 1221. A side frame 1223 is fixedly connected to one end of the filter box 3. A drive rod 1224 is rotatably connected to both ends inside the side frame 1223. A drive bevel tooth 1225 is fixedly connected to the outer wall of the drive rod 1224. The top end of the drive rod 1224 extends to the top end of the side frame 1223 and is fixedly connected to the bottom of the motor assembly 1226. One end of the drive gear 1220 is fixedly connected to one end of the third conical tooth 1227.The transmission rod 1201 rotates with both ends inside the filter box 3; the cam 1202 is hinged to the beater seat 1203; the drive gear 1220 rotates with the outer wall of the filter box 3; the internally threaded push plate 1214 is threadedly connected to the reciprocating screw 1215; the guide rod 1213 slides with the internally threaded push plate 1214; and several drive bevel teeth 1225 are fixed to the outer side of the drive rod 1224, each of which meshes with the first bevel tooth 1217, the second bevel tooth 1222, and the third bevel tooth 1227.

[0023] See attached document Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , and 11 and Figure 12When the exhaust gas purification device is in use, the exhaust gas is drawn in from the bottom of the filter box 3 by the gas collection hood 1 and flows upward. During the flow, particulate matter in the exhaust gas is filtered and blocked by the filter cloth 11. However, the filter cloth 11 is prone to clogging over time. Therefore, the motor assembly 1226 drives the drive rod 1224 to rotate several drive bevel teeth 1225, which in turn drive the first bevel tooth 1217, the drive gear 1220, and the second bevel tooth 1222 in sequence. When the first bevel tooth 1217 rotates, the connecting rod 1216 drives the reciprocating screw 1215. At this time, the reciprocating screw... The threaded push plate 1214, connected to the rod 1215, reciprocates along the guide rod 1213 on the inner side of the side frame 1212. During the movement, the threaded push plate 1214 pushes and pulls the push-pull seat 1211, thereby causing the hinged push rod 1209 to push and pull the top of the main air plate 1208. Since several auxiliary air plates 1206 are hinged to the main air plate 1208 through the hinge rod 1207, and the bottoms of the auxiliary air plates 1206 and the main air plate 1208 are hinged to the bottom of the second support seat 10, when the main air plate 1208 is pushed and pulled, it will move along with the several auxiliary air plates 1215. The 06 reciprocating oscillation allows the exhaust gas flowing through the second support 10 to pass evenly through the filter cloth 11 under the guidance of the auxiliary air plate 1206 and the main air plate 1208, thus prolonging the time before the filter cloth 11 becomes clogged. When the second conical tooth 1222 is driven, several pulley assemblies 1221 are driven, causing the transmission rod 1201 to drive the cam 1202 to rotate at a constant speed. During rotation, the striking seat 1203 continuously strikes the top of the filter cloth 11, thereby knocking off particulate impurities adsorbed at the bottom of the filter cloth 11, thus reducing the likelihood of the filter cloth 11 becoming clogged. It is possible that the remaining exhaust gas will be filtered by the activated carbon and other filter materials inside the filter material assembly 9 when it passes through the filter material assembly 9. The filter material assembly 9 is also prone to local filtration failure due to uneven distribution during exhaust gas flow. To address this, a set of drive gears 1220 is connected to the third conical tooth 1227. When the third conical tooth 1227 is driven, the drive gear 1220 drives the baffle 1218 to rotate at a low speed through meshing with the drive gear sleeve 1219. Since the baffle 1218 is perforated, the filter material assembly 9 can be used in sections, making the adsorption and filtration distribution of the filter material assembly 9 more uniform.
