A coating exhaust gas treatment device

Abstract

The present application relates to the technical field of coating exhaust treatment, in particular to a coating exhaust treatment device, which comprises a bearing mechanism and an exhaust gas filtering mechanism installed on the bearing mechanism. The coating in the exhaust gas can be filtered by the solution in the inner cavity of the material gathering bin. At this time, the coating can float on the top layer of the water solution in the inner cavity of the material gathering bin. When the coating gathers a certain amount, the hydraulic sub-rod in the hydraulic rod part will cooperate with the traction plate to drive the boost rod to perform lifting operation. At this time, the extruding column head fixed at the bottom of the boost rod can extrude the coating floating in the inner cavity of the material gathering bin towards the inner cavities of the plurality of material guiding pipes. Finally, the extruded coating will gather in the material gathering ring pipe. When the extruding column head stops working, the operator can control the inhaul cable to stretch outward until the ends of the two scraping parts empty the coating in the inner cavity of the material gathering ring pipe outward, thereby effectively ensuring that the exhaust gas is guided inside the pipeline while avoiding the problem of adhesion and pollution of the coating to the inner wall of the pipeline and the exhaust mechanism.

Description

Technical Field

[0001] This invention relates to the field of coating exhaust gas treatment technology, specifically to a coating exhaust gas treatment device. Background Technology

[0002] The main sources of paint exhaust gas are the spraying and drying processes. The pollutants emitted are mainly paint mist and organic solvents generated during spraying and organic solvents generated during drying and evaporation. Paint mist mainly comes from the part of solvent-based paint that is scattered during air spraying operations. Its composition is consistent with the paint used. Organic solvents mainly come from solvents and thinners used in the paint application process. The vast majority of them are volatile emissions, and the main pollutants are xylene, benzene, toluene, etc.

[0003] Currently, the main sources of harmful exhaust gases emitted during painting are spray booths, drying rooms, and baking rooms. When paint mist diffuses in a sealed room, existing exhaust equipment will directly transfer the paint mist to the collection equipment through the exhaust fan mechanism. However, the paint in the mist is difficult to dry in a short time. Direct drainage will cause the paint in the mist to stick to the surface of the exhaust mechanism. Over time, the inner wall of the drainage pipe will become more prone to accumulating bacteria and dirt due to the increased accumulation of paint. In severe cases, it will affect the internal environment of the work area through the pipe.

[0004] Regarding the safe guidance of painting exhaust gas, the technical challenge that this invention aims to address is how to prevent undried paint in the exhaust gas from adhering to the inner wall of the pipe and the surface of the exhaust mechanism, which could lead to the accumulation of bacteria and contaminants in the air. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted in this invention is as follows: A coating exhaust gas treatment device includes a supporting mechanism, an exhaust gas collection and filtration mechanism mounted on the supporting mechanism, and a filter media discharge mechanism mounted on the exhaust gas collection and filtration mechanism. The supporting mechanism includes a horizontally positioned hood, an exhaust assembly installed inside the hood, two seals located outside the hood, a support plate bolted to the bottom of the seals, two beams installed inside guide tubes on both sides of the support plate, two clamps installed at both ends of the two beams, and a first and second pad bolted to the top of the support plate. The exhaust gas collection and filtration mechanism includes a guide pipe connected to the hood, a filter chamber connected to the guide pipe, a material collection chamber installed outside the filter chamber, and a rectangular tube installed in the middle of the filter chamber and the material collection chamber. The filter media discharge mechanism includes a limiting end post in the channel, multiple feed pipes evenly installed in the middle of the material collection bin, a material collection ring pipe installed at the bottom of the multiple feed pipes, a rubber plug installed in the bottom column head of the material collection bin, two scrapers located in the inner cavity of the material collection ring pipe and connected to both ends of the reinforcing tension spring, and a cable installed on the ropes of the two scrapers. The filter media discharge mechanism includes a push rod movably installed inside the limiting end post, a spring connected between the limiting end post and the push rod, a material extrusion column head fixedly installed at the bottom end of the push rod and located in the inner cavity of the material collection bin, two sets of clamps fixedly installed outside the filter bin, vertically distributed hydraulic rods fixedly installed in the two sets of clamps, and a traction plate connected to the top of the hydraulic sub-rod inside the hydraulic rod.

[0007] In a preferred embodiment, the present invention may be further configured such that: the pallet is made of stainless steel, and an elliptical cavity is formed inside the pallet on the side near the second pad, while the transverse grooves inside the second pad and the elliptical cavity are symmetrically distributed vertically.

[0008] By adopting the above technical solution, a first pad and a second pad are installed at the bottom of the combined post-filter chamber and the aggregate chamber, respectively, and a horizontal support plate is set directly below the first pad and the second pad. At this time, the first pad and the second pad are fixed to the top of the support plate with bolts. The transverse groove inside the second pad is symmetrical and connected to the elliptical cavity inside the support plate. As the hydraulic rod inside the hydraulic rod rises and falls, the push rod fixed by the traction plate can cooperate with the extrusion column head to extrude the coating floating in the inner cavity of the aggregate chamber into the inner cavity of multiple feed pipes.

[0009] In a preferred embodiment, the present invention can be further configured such that the exhaust assembly is composed of a motor and a turbine fan blade mounted on the internal drive shaft of the motor, and the outer casing of the motor is fixedly installed in a slot at one end of the shroud.

[0010] By adopting the above technical solution, the motor is fixedly installed inside the shroud. At this time, the internal drive shaft of the motor and the fixed turbine blades are located in the inner cavity of the shroud. As the motor starts, its internal drive shaft and turbine blades can attract the exhaust gas, and the attracted exhaust gas can be discharged from the solution inside the aggregate bin and the filter bin.

[0011] In a preferred embodiment, the present invention can be further configured such that: an L-shaped exhaust pipe is installed at the top of the air filtration chamber, an air inlet pipe for attracting waste gas is installed in the middle of the material collection chamber, and an oblique hole communicating with the inner cavity of the material inlet pipe is opened on the inner wall of the material collection chamber.

[0012] By adopting the above technical solution, by opening oblique holes in a circular pattern on the inner wall of the polymer silo, and connecting the oblique holes in the inner wall of the polymer silo with the inner cavity of the feed pipe, when the hood exhausts air outward, the exhaust gas can enter from the air inlet pipe outside the polymer silo. At this time, the hose that runs through the air inlet pipe into the solution inside the polymer silo can directly introduce the exhaust gas. Finally, the coating in the exhaust gas will float to the top of the solution. With the lifting and lowering of the hydraulic rod in the hydraulic rod, the push rod can drive the extrusion column head to extrude the floating coating into the multiple feed pipes.

[0013] In a preferred embodiment, the present invention can be further configured as follows: both the material-collecting ring tube and the feed tube are made of ceramic material, and a drain vertical pipe is installed at the bottom of the material-collecting ring tube near the cable side. An insert rod is fixedly installed inside the cavity of the end of the material-collecting ring tube away from the cable, and a reinforcing tension spring is connected to the insert rod. The scraper is composed of a rectangular end and a tie rope, with one end of the tie rope connected to the outside of the rectangular end and the other end of the tie rope penetrating to the outside of the material-collecting ring tube.

[0014] By adopting the above technical solution, the feed tube and the material collection ring tube are made of ceramic material. With the smoothness of the feed tube and the material collection ring tube themselves, when the coating is squeezed into the inner cavity of the feed tube, the wet coating can quickly gather from the inner cavity of the feed tube to the inner cavity of the material collection ring tube.

[0015] In a preferred embodiment, the present invention may be further configured such that the traction plate is composed of two I-shaped clamps and an end plate, and the two I-shaped clamps are respectively installed on the outside of the booster rod and the hydraulic sub-rod.

[0016] By adopting the above technical solution, the hydraulic sub-rod and the push rod inside the hydraulic rod are fixed by the traction plate. At this time, the push rod, which is vertically distributed and extends into the limiting end column, can be pressed and push the extrusion column head to move up and down along the inner cavity of the aggregate bin. At this time, the coating material filtered by the solution in the inner cavity of the aggregate bin can be continuously extruded by the extrusion column head into the inner cavity of multiple feed pipes.

[0017] In a preferred embodiment, the present invention may be further configured such that: a circular washer is fixedly installed in the middle of the push rod and supported on the top of the spring, and a cylindrical plug is installed at the top of the push rod, penetrating into the inner cavity of the aggregate bin.

[0018] By adopting the above technical solution, the top of the spring is fixed on the circular pad in the middle of the push rod, and the bottom of the spring is fixed on the top of the limiting end column. When the hydraulic rod and the traction plate drive the push rod to move up and down repeatedly, the pressure of the extrusion column head in the solution being obstructed during the reciprocating movement can be relieved by the spring.

[0019] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention involves setting up horizontally distributed air-filtering chambers and material-aggregating chambers, with a rectangular pipe fixedly installed between them. Multiple circumferentially distributed feed pipes are fixedly installed in the center of the material-aggregating chamber. The inclined channels inside the feed pipes connect with the inner cavity of the material-aggregating ring pipe. When exhaust gas is drawn in through the air inlet pipe in the center of the material-aggregating chamber, the coating material in the exhaust gas is filtered by the solution inside the chamber. The coating material then floats on top of the aqueous solution inside the chamber. Once a certain amount of coating material has accumulated, the hydraulic rod inside the hydraulic rod... The system works in conjunction with a traction plate to drive a booster rod for lifting and lowering. At this time, the extrusion column head fixed at the bottom of the booster rod can squeeze the coating floating in the inner cavity of the material collection bin towards the inner cavities of multiple feed pipes. Finally, the squeezed coating will gather from the inner cavity of the material collection ring pipe. When the extrusion column head stops working, the operator can control the cable to pull outward until the ends of the two scrapers discharge the coating from the inner cavity of the material collection ring pipe. This effectively ensures that the exhaust gas is guided inside the pipeline while avoiding the problem of coating sticking and accumulating dirt on the inner wall of the pipeline and the exhaust mechanism.

[0020] 2. This invention involves setting up a filter chamber outside the aggregate silo and connecting the aggregate silo and the filter chamber using a rectangular pipe. The solution injected into the combined filter chamber and aggregate silo can then perform dual filtration of the coating in the exhaust gas. Two end pipes are installed at the bottom of the outer sides of both the filter chamber and the aggregate silo. When it is necessary to replace the turbid solution inside the aggregate silo, the operator can connect an external water pipe to the two end pipes. The water pipe connected to the external end pipe of the aggregate silo can then continuously guide the solution into the filter chamber. The turbid solution can then be discharged through the filter chamber into the other water pipe. This device can safely replace the turbid solution without stopping the exhaust gas flow, thus greatly improving the device's ability to quickly filter coating in the exhaust gas.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a coating exhaust gas treatment device provided by the present invention. Example 1:

[0026] Combination Figures 1-8 As shown, the present invention provides a coating exhaust gas treatment device, including a support mechanism 100, an exhaust gas collection and filtration mechanism 200 installed on the support mechanism 100, and a filter material discharge mechanism 300 installed on the exhaust gas collection and filtration mechanism 200.

[0027] The supporting mechanism 100 includes a support plate 110, a beam 120, a clamp 130, a first pad 140, a second pad 150, a seal 160, a fan hood 170, and an exhaust assembly 180. The waste gas collection and filtration mechanism 200 includes a filter chamber 210, a material collection chamber 220, a limiting end post 230, a guide pipe 240, a feed pipe 250, a material collection ring pipe 260, a rubber plug 270, a scraper 280, and a cable 290. The filter material discharge mechanism 300 includes a clamp 310, a hydraulic rod 320, a traction plate 330, a pusher rod 340, a spring 350, and a material extrusion column head 360.

[0028] Specifically, the exhaust assembly 180 is installed inside the hood 170, two seals 160 are located outside the hood 170, the support plate 110 is bolted to the bottom of the seals 160, two beams 120 are installed inside the guide tubes on both sides of the support plate 110, two clamps 130 are installed at both ends of the two beams 120, the first pad 140 and the second pad 150 are bolted to the top of the support plate 110, the guide pipe 240 is connected to the hood 170, the filter chamber 210 is connected to the guide pipe 240, the material collection chamber 220 is installed outside the filter chamber 210, the limiting end post 230 is installed in the rectangular pipe in the middle of the filter chamber 210 and the material collection chamber 220, multiple feed pipes 250 are evenly installed in the middle of the material collection chamber 220, and the material collection ring... Pipe 260 is installed at the bottom of multiple feed pipes 250, rubber plug 270 is installed in the column head at the bottom of the inner cavity of the material collection bin 220, two scrapers 280 connected to both ends of the reinforcing tension spring are located in the inner cavity of the material collection ring pipe 260, cable 290 is installed on the rope of the two scrapers 280, push rod 340 is movably installed inside the limiting end column 230, spring 350 is connected between the limiting end column 230 and push rod 340, extrusion column head 360 located in the inner cavity of the material collection bin 220 is fixedly installed at the bottom end of push rod 340, two sets of clamps 310 are fixedly installed outside the air filter bin 210, vertically distributed hydraulic rods 320 are fixedly installed inside the two sets of clamps 310, and traction plate 330 is connected to the top of the hydraulic sub-rod inside the hydraulic rod 320.

[0029] Multiple feed pipes 250, arranged in a circular pattern, are fixedly installed in the middle of the aggregate bin 220. The inclined channels inside the feed pipes 250 connect with the inner cavity of the aggregate ring pipe 260. When exhaust gas is drawn in through the air inlet pipe in the middle of the aggregate bin 220, the paint in the exhaust gas is filtered by the solution inside the aggregate bin 220. The paint then floats on top of the aqueous solution inside the aggregate bin 220. When a certain amount of paint has accumulated, the hydraulic rod inside the hydraulic rod 320, in conjunction with the traction plate 330, drives the push rod 340 to perform lifting operations. At this time, the extrusion head 360 fixed at the bottom of the push rod 340 can squeeze the paint floating inside the aggregate bin 220 towards the inner cavity of the multiple feed pipes 250. Finally, the squeezed paint will accumulate inside the aggregate ring pipe 260. After operation 60 stops, the operator can control the cable 290 to pull outward until the ends of the two scrapers 280 discharge the coating inside the polymer ring pipe 260, thus effectively ensuring that the exhaust gas is guided inside the pipe. Two end pipes are installed at the bottom of the outer side of the filter chamber 210 and the polymer chamber 220 respectively. When it is necessary to replace the turbid solution inside the polymer chamber 220, the operator can connect the external water pipe to the two end pipes. At this time, the water pipe connected to the external end pipe of the polymer chamber 220 can continuously guide the solution into the filter chamber 210. The turbid solution can then be discharged into another water pipe along the inner cavity of the filter chamber 210. In this way, the device can safely replace the turbid solution without stopping the exhaust gas from entering. Example 2:

[0030] Combination Figures 3-8 As shown, based on Embodiment 1, the tray 110 is made of stainless steel, and the tray 110 has an elliptical cavity on the side near the second pad 150. The horizontal grooves inside the second pad 150 and the elliptical cavity are symmetrically distributed vertically. The exhaust assembly 180 is composed of a motor and a turbine fan blade installed on the internal drive shaft of the motor. The outer housing of the motor is fixedly installed in the slot at one end of the shroud 170.

[0031] A first pad 140 and a second pad 150 are respectively installed at the bottom of the combined post-filter chamber 210 and the aggregate chamber 220. A horizontal support plate 110 is set directly below the first pad 140 and the second pad 150. At this time, the first pad 140 and the second pad 150 are bolted to the top of the support plate 110. The transverse groove inside the second pad 150 is symmetrical and connected to the elliptical cavity inside the support plate 110. At the same time, the motor is fixedly installed inside the fan cover 170. At this time, the drive shaft inside the motor and the fixed vortex The turbine blades are located inside the shroud 170. As the motor starts, its internal drive shaft and turbine blades can draw in the exhaust gas. The exhaust gas drawn in can then be discharged from the solution inside the aggregate bin 220 and the filter bin 210. As the hydraulic rod inside the hydraulic rod 320 rises and falls, the push rod 340, which is fixed by the traction plate 330, can work with the extrusion column head 360 to squeeze the coating floating in the inner cavity of the aggregate bin 220 into the inner cavity of multiple feed pipes 250. Finally, the exhaust gas can be filtered by the solution and safely discharged. Example 3:

[0032] Combination Figures 5-8 As shown, based on Embodiment 1, an L-shaped exhaust pipe is installed on the top of the air filter chamber 210, an air intake pipe for attracting exhaust gas is installed in the middle of the material collection chamber 220, and an oblique hole connected to the inner cavity of the material inlet pipe 250 is opened on the inner wall of the material collection chamber 220. The material collection ring pipe 260 and the material inlet pipe 250 are both made of ceramic material, and a sewage discharge vertical pipe is installed at the bottom of the material collection ring pipe 260 near the cable 290. An insert rod is fixedly installed inside the cavity of the end of the material collection ring pipe 260 away from the cable 290, and a reinforcing tension spring is connected to the insert rod. The scraper 280 is composed of a rectangular end and a rope, and one end of the rope is connected to the outside of the rectangular end, while the other end of the rope passes through to the outside of the material collection ring pipe 260.

[0033] By utilizing the circumferentially distributed oblique holes on the inner wall of the aggregate bin 220, and the connection between these oblique holes and the inner cavity of the feed pipe 250, when the hood 170 exhausts air, the exhaust gas can enter through the air inlet pipe outside the aggregate bin 220. At this time, the flexible hose extending from the air inlet pipe into the solution inside the aggregate bin 220 can directly introduce the exhaust gas. Ultimately, the coating material in the exhaust gas will float to the top of the solution. With the rising and falling movement of the hydraulic rod within the hydraulic rod 320, the push rod 340 can drive the extrusion column head 360 to push the floating coating material towards the multiple feed pipes 250. The internal extrusion mechanism, combined with the smoothness of the feed pipe 250 and the material gathering ring pipe 260, allows the wet paint to quickly gather from the inner cavity of the feed pipe 250 towards the inner cavity of the material gathering ring pipe 260 after being squeezed into the inner cavity of the feed pipe 250. When the gathered paint is difficult to remove, the pull cable 290 can be pulled outward. At this time, the rectangular ends of the two scrapers 280 can scrape off the accumulated paint under the action of the reinforced tension spring, ensuring that the paint does not accumulate and stick to the inner wall of the pipe and the surface of the exhaust mechanism during the treatment of exhaust gas, thereby reducing the accumulation of bacteria and dirt. Example 4:

[0034] Combination Figures 5-8 As shown, based on Embodiment 1, the traction plate 330 is composed of two I-shaped clamping columns and an end plate. The two I-shaped clamping columns are respectively installed on the outside of the push rod 340 and the hydraulic sub-rod. The middle part of the push rod 340 is fixedly installed with a circular washer that is supported on the top of the spring 350, and the top of the push rod 340 is installed with a cylindrical plug that penetrates into the inner cavity of the material storage bin 220.

[0035] The hydraulic rod and push rod 340 inside the hydraulic rod 320 are fixed by the traction plate 330. At this time, the push rod 340, which is vertically distributed and extends into the limiting end column 230, can be pressed to push the extrusion head 360 to move up and down along the inner cavity of the aggregate bin 220. At this time, the coating filtered by the solution in the inner cavity of the aggregate bin 220 can be continuously extruded by the extrusion head 360 into the inner cavity of multiple feed pipes 250. At this time, the device can also be used in conjunction with the continuous absorption and treatment of waste gas. The bottom end of the spring 350 is fixed to the top of the limiting end column 230. When the hydraulic rod and the traction plate 330 drive the push rod 340 to move up and down, the pressure of the extrusion head 360 in the solution during the reciprocating up and down process can be relieved by the spring 350, thereby ensuring that the extrusion head 360 can continuously extrude and discharge the floating coating.

[0036] The working principle and usage process of this invention: Two scrapers 280 are pre-connected by a reinforcing tension spring, passing through the two ends of the material-aggregating ring tube 260. Under the traction of the reinforcing tension spring, the inner ends of the two scrapers 280 contract to the deepest part of the material-aggregating ring tube 260. The ropes of the two scrapers 280, away from the reinforcing tension spring, pass outwards from the outer end of the extrusion column head 360. The two rope ends of the two scrapers 280 passing through the material-aggregating ring tube 260 are fixed by the top partition of the cable 290. After assembly, the material-aggregating ring tube 260 is connected to the inner cavity of the material-aggregating bin 220 through multiple feed pipes 250. The adjacent air-filtering bin 210 and the material-aggregating bin 220 are connected by a rectangular pipe. At this time, the push rod... The rod at the bottom of the push rod 340 will penetrate into the rubber plug 270 and into the inner cavity of the material collection bin 220. The bottom end of the push rod 340 will be fixedly installed on the bottom end of the extrusion head 360. At this time, the extrusion head 360 will fit into the inner cavity of the material collection bin 220. The top end of the push rod 340 will penetrate into the pipe at the top of the material collection bin 220. Then, the pipe at the top of the air filter bin 210 will be connected to the hood 170 using the guide pipe 240. At this time, the inner cavities of the air filter bin 210, the material collection bin 220 and the hood 170 will be in a connected state. The motor in the exhaust assembly 180 is fixedly installed in the middle of the hood 170, and the turbine fan blades are installed on the rod that is installed in the drive shaft of the motor and penetrates into the inner cavity of the hood 170. During use, when the motor inside the exhaust assembly 180 starts and runs, its internal drive shaft and turbine blades rotate at high speed inside the shroud 170. At this time, the shroud 170 discharges air outward, and the combined aggregate bin 220 and filter bin 210 absorb and filter the exhaust gas collected after coating. The paint in the exhaust gas is filtered by the aqueous solution inside the aggregate bin 220, and the paint floats on the top layer of the solution inside the aggregate bin 220. The filtered gas is transferred from the solution inside the aggregate bin 220 to the shroud 210, and finally discharged outward through the guide pipe 240 and the shroud 170. When the paint on the top layer of the solution inside the aggregate bin 220 gathers... Once a certain amount is reached, the hydraulic rod inside the hydraulic rod 320 can be controlled to move vertically. At this time, the push rod 340, which is fixed by the traction plate 330, can work with the extrusion column head 360 to squeeze the coating floating in the inner cavity of the material collection bin 220 into the multiple feed pipes 250. As the coating is guided by the multiple feed pipes 250, it will eventually gather inside the material collection ring pipe 260. When the hydraulic rod 320 stops and the coating stops flowing from the feed pipe 250, the operator can pull it outward with the cable 290. At this time, the two scrapers 280 pulled by the cable 290 can work with the reinforcement spring to discharge the coating gathered in the inner cavity of the material collection ring pipe 260 outward.

[0037] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
