Description

Technical Field

[0001] This invention relates to the field of filtration technology in coating production lines, specifically a filtration and dust removal device for coating production lines. Background Technology

[0002] Dust filtration in coating production lines is essential because the spraying process generates paint mist, dust, and volatile organic compounds (VOCs). Direct emission of these impurities would pollute the workshop environment, harm the health of operators, and potentially adhere to the surface of workpieces, causing defects such as particles and pinholes in the coating, thus affecting product quality. Dust filtration effectively captures paint mist and dust, purifies the air, and ensures a compliant production environment. Simultaneously, it reduces wear on coating equipment, extends equipment lifespan, ensures a stable coating process, improves coating uniformity and smoothness, and meets product quality requirements.

[0003] A dust removal filtration device disclosed in patent publication number CN115708981A includes a backflush pipe and a filter screen. When a large amount of dust accumulates on the filter screen and needs cleaning, a differential pressure is generated across the filter screen, activating the backflush valve. Air is blown through the backflush pipe towards the air outlet end of the process pipeline, thereby blowing off the dust adhering to the filter screen and preventing it from becoming clogged. Since there is no need to replace the filter bag, and the problem of dust adhesion to the filter screen is solved by backflush, the production line can operate continuously for a long time without stopping the production line. Furthermore, it eliminates the need for bulky filter bags, resulting in a simple and reliable structure that saves a significant amount of space. The filter screen can be used for a long time, eliminating the need for consumables like filter bags and preventing dust leakage due to filter bag damage, thus ensuring filtration quality.

[0004] When the above-mentioned device is filtering, the filtration resistance fluctuates greatly. When the fixed filter plate is partially blocked, it cannot be switched to the clean area by rotation, which will cause the overall filtration resistance to rise sharply and increase the system energy consumption. If the fixed filter plate is partially damaged, it is often necessary to stop the machine for complete disassembly and replacement. In order to address the above problems, a filtration and dust removal device for a coating production line is proposed. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0040] Please see Figures 1-8 In this embodiment, a dust removal and filtration device for a coating production line includes a filter box 11 and a coating device 12 disposed on one side of the filter box 11. The filter box 11 is provided with a filter assembly 13 for filtering the gas.

[0041] The filter assembly 13 includes a rotating frame 131 and several sets of inclined plates 132. The rotating frame 131 is rotatably mounted inside the filter box 11. The several sets of inclined plates 132 are fixedly connected to the surface of the rotating frame 131. Several sets of filter elements 133 are arranged inside the inclined plates 132. An air outlet frame 134 is arranged inside the inclined plates 132. Several sets of air outlet pipes 135 are arranged on the air outlet frame 134. The air inlet of the air outlet frame 134 is connected to a delivery pipe 136. Gas is blown towards the rotating frame 131, and the several sets of inclined plates 132 drive the rotating frame 131 to rotate, filtering impurities in the gas. The frame rotates continuously during filtration, and the filter can be switched to a clean setting. In this area, to reduce filtration resistance and system energy consumption, the delivery pipe 136 is connected to an existing external blower to deliver gas to the air outlet frame 134. Then, several sets of air outlet pipes 135 blow the gas out to back-blow the dust on the filter element 133. When the gas blows outward in the air outlet pipe 135, the gas blows the plug 163 outward. The plug 163 drives the limit rod 162 to slide on the fixed plate 161 and squeeze the spring 164. The back-blown gas will impact the filter element 133, causing the dust on the filter element 133 to fall into the collection hopper 20, which facilitates the cleaning of the filter element 133, reduces manual intervention and downtime, and reduces production losses caused by maintenance.

[0042] Limiting components 14 are disposed on both sides of the filter assembly 13 and are used to guide the rotation of the filter assembly 13.

[0043] Mounting component 15 is located on one side of filter box 11 and is used for disassembling and installing filter component 13.

[0044] The protective component 16 is installed on the air outlet 135 to protect the air outlet of the air outlet 135 and to backwash the filter element 133.

[0045] The adsorption component 17 is installed inside the filter box 11 and is used to filter the paint carried in the gas.

[0046] The air guide plate 18 is set on both sides of the inner wall of the filter box 11 and located on the top of the rotating frame 131 to guide the gas.

[0047] The circulation assembly 19 is located on one side of the filter box 11 and is used for circulating and transporting gas.

[0048] A collection hopper 20 is located at the bottom of the inner wall of the filter box 11; and,

[0049] The collection component 21 is set on the collection hopper 20 and is used to collect the impurities after backflushing.

[0050] The limiting assembly 14 includes two sets of baffles 141 and a set of limiting blocks 142. One set of baffles 141 is rotatably connected to one side of the rotating frame 131, and the other set of baffles 141 is bolted to the other side of the rotating frame 131. The limiting blocks 142 are fixedly connected to the side of one set of baffles 141 away from the rotating frame 131. One side of the inner wall of the filter box 11 has a slot 143 for engaging the baffles 141, and a limiting groove 144 for engaging the limiting blocks 142. One side of the air outlet frame 134 is bolted and clipped to one side of the other set of baffles 141. Pulling the box door 151 outward causes the limiting blocks 142 to disengage from the limiting groove 144, and the baffles 141 to disengage from the slot 143, facilitating the positioning of the rotating frame 131 during installation and rotation.

[0051] The mounting assembly 15 includes a door 151 and a recess 152. The door 151 is rotatably connected to another set of baffles 141 on the side away from the rotating frame 131. A recess 152 is provided on one side of the filter box 11 for the door 151 to engage. Two sets of positioning blocks 153 are fixedly connected to the side of the door 151 away from the baffles 141. Two sets of fixing blocks 154 are fixedly connected to one side of the filter box 11. Positioning grooves 155 are provided on the fixing blocks 154 for engaging the positioning blocks 153. The positioning blocks 153 and positioning grooves 155 are fixed by bolts. The outer wall of the recess 152 is provided with… With sealing rubber, the conveying pipe 136 is rotatably connected to another set of baffles 141 and the door 151, and extends to the outside of the filter box 11. A handle is installed on one side of the door 151. The bolts are removed using external tools. By holding the handle and rotating the door 151, the door 151 drives the positioning block 153 to slide outward in the positioning groove 155. After pulling the door 151 outward, the rotating frame 131 is completely removed. The bolts on one side of the filter element 133 are then removed using tools. The filter element 133 can be removed from the rotating frame 131 for replacement and maintenance, avoiding the need for complete replacement, which would affect production efficiency and reduce resource waste.

[0052] The protective component 16 includes a fixed plate 161 and a limiting rod 162. The fixed plate 161 is fixedly connected inside the air outlet pipe 135. The limiting rod 162 is slidably connected to the fixed plate 161. A plug 163 is fixedly connected to one side of the limiting rod 162. One side of the plug 163 is engaged with the air outlet of the air outlet pipe 135. A spring 164 is sleeved on the limiting rod 162. One end of the spring 164 is connected to one side of the fixed plate 161, and the end of the spring 164 away from the fixed plate 161 is connected to the limiting rod 162. When the gas blows out of the air outlet pipe 135, the gas blows the plug 163 outward. The plug 163 drives the limiting rod 162 to slide on the fixed plate 161 and squeeze the spring 164, which can prevent impurities and dust from clogging the air outlet of the air outlet pipe 135 during gas filtration.

[0053] The adsorption assembly 17 includes two sets of arc-shaped plates 171 and a collection box 172. The two sets of arc-shaped plates 171 are fixedly connected inside the filter box 11, and the collection box 172 is fixedly connected between the two sets of arc-shaped plates 171. Two sets of powder spraying pipes 173 are provided on the top of each arc-shaped plate 171. The two ends of each set of powder spraying pipes 173 are fixedly connected to both sides of the inner wall of the filter box 11. The inlets of the two sets of powder spraying pipes 173 are connected to a discharge pipe 174. The inlet of the discharge pipe 174 is connected to a first pump body 175, which is installed on the top of the filter box 11. The inlet of the first pump body 175 is connected to the storage tower 177 via the connecting pipe 176. The storage tower 177 is located on one side of the filter box 11. The collection box 172 is equipped with a recovery component 22 for collecting lime. When the first pump body 175 is started, the lime powder in the storage tower 177 is transported to the discharge pipe 174 through the connecting pipe 176. Then, the gas is sprayed out by two sets of powder spraying pipes 173 to adsorb and capture the dye particles suspended in the gas. After the dye particles in the gas are adsorbed, they fall downward into the collection box 172. The recovery component 22 recovers the lime powder that has adsorbed the dye particles.

[0054] The circulation component 19 includes a negative pressure unit 191 and a feed pipe 192. The negative pressure unit 191 is installed between the filter box 11 and the coating equipment 12. The feed pipe 192 is installed on the top of the coating equipment 12. The outlet of the feed pipe 192 is installed on the top of the filter box 11 and is connected to the inner cavity of the filter box 11. The air inlet of the negative pressure unit 191 is connected to the exhaust pipe 193. The exhaust pipe 193 is installed on one side of the filter box 11 and is connected to the inner cavity of the filter box 11. The air outlet of the feed pipe 192 is connected to the air inlet provided on one side of the coating equipment 12. When the negative pressure unit 191 is started, a negative pressure is generated in the filter box 11, and the gas generated during coating in the coating equipment 12 is transported to the filter box 11 through the feed pipe 192. After the gas is filtered, it is discharged through the exhaust pipe 193 and then transported to the coating equipment 12 for blowing by the feed pipe 192, which facilitates the collection of suspended particles during the spraying process.

[0055] The collection component 21 includes a discharge pipe 211 and a waste collection box 212. The discharge pipe 211 is installed on one side of the collection hopper 20 and extends to the outside of the filter box 11. The outlet of the discharge pipe 211 is connected to a third pump body inside the waste collection box 212. The third pump body inside the waste collection box 212 operates to collect dust and impurities through the discharge pipe 211.

[0056] The recycling assembly 22 includes an auger conveyor rod 221 and a collection box 222. The auger conveyor rod 221 is rotatably connected inside the collection box 172. The collection box 222 is fixedly connected to the bottom of the collection box 172 and communicates with the collection box 172. The discharge port of the collection box 222 is connected to a conveying pipe 223. The conveying pipe 223 is installed on one side of the filter box 11. The discharge port of the conveying pipe 223 is connected to a second pump in the storage tower 177. A motor 224 is installed on one side of the filter box 11 to drive the auger conveyor rod 221 to rotate. When the motor 224 is started, it drives the auger conveyor rod 221 to rotate, conveying the lime powder and dye particles in the collection box 172 into the collection box 222. The second pump in the storage tower 177 is started, conveying the lime powder and dye particles in the collection box 222 into the storage tower 177 through the conveying pipe 223, which facilitates the recovery of lime powder that has adsorbed dye particles.

[0057] A connecting pipe 23 is provided on one side of the filter box 11. Both ends of the connecting pipe 23 are installed on one side of the filter box 11. The air inlet of the connecting pipe 23 is located above the arc plate 171, and the air outlet of the connecting pipe 23 is located above the air guide plate 18. By setting the connecting pipe 23, it is convenient to filter impurities in the gas after the dye particles have been filtered.

[0058] The inclined plates 132 are evenly arranged around the central axis of the rotating frame 131 to facilitate the rotation of the rotating frame 131 by the inclined plates 132. Limiting plates 24 are provided on both sides of the rotating frame 131. The two sets of limiting plates 24 are fixedly connected to the two sides of the inner wall of the filter box 11. One side of the limiting plate 24 is slidably engaged with the inclined plate 132. The setting of the limiting plate 24 can guide and limit the gas, so that the gas can pass through the filter element 133 for filtration.

[0059] The working principle of this invention is as follows: During use, the negative pressure unit 191 starts, creating negative pressure inside the filter box 11. The gas generated during coating in the coating equipment 12 is then transported to the filter box 11 through the feed pipe 192. Simultaneously, the first pump 175 starts, transporting the lime powder in the storage tower 177 to the discharge pipe 174 through the connecting pipe 176. The gas is then sprayed out by two sets of powder spraying pipes 173, adsorbing and capturing suspended dye particles in the gas. After being adsorbed, the dye particles fall downwards into the collection box 172. When the negative pressure unit 191 stops running, the motor 224 starts, driving the auger conveyor... The conveyor rod 221 rotates to transport the lime powder and dye particles in the collection box 172 to the collection tank 222. The second pump in the storage tower 177 is started to transport the lime powder and dye particles in the collection box 222 to the storage tower 177 through the conveyor pipe 223. The gas is blown through the connecting pipe 23 to the guide plate 18 and blown towards the rotating frame 131 by the guide plate 18. As the gas is blown, several sets of inclined plates 132 drive the rotating frame 131 to rotate, filtering the impurities in the gas. The continuous rotation during filtration can switch to a clean area, reduce filtration resistance, and reduce system energy consumption.

[0060] After being filtered, the gas is discharged through the exhaust pipe 193 and then conveyed to the coating equipment 12 through the feed pipe 192 for blowing, which facilitates the collection of suspended particles during the spraying process. After the negative pressure machine 191 stops, the conveying pipe 136 is connected to the existing external blower to convey the gas to the air outlet frame 134, and then blown out by several sets of air outlet pipes 135 to back-blow the dust on the filter element 133. When the gas is blown outward in the air outlet pipe 135, the gas blows the plug 163 outward, and the plug 163 drives the limit rod 162 to stay in place. The gas slides on the fixed plate 161 and squeezes the spring 164. The back-blowing gas impacts the filter element 133, causing the dust on the filter element 133 to fall into the collection hopper 20, which facilitates cleaning of the filter element 133, reduces manual intervention and downtime, and reduces production losses caused by maintenance. At the same time, the gas pushes the inclined plate 132 to drive the rotating frame 131 to rotate, so that all the dust falls into the collection hopper 20. The third pump in the waste collection box 212 works to collect dust and impurities through the discharge pipe 211.

[0061] When the filter element 133 needs to be inspected or replaced, first use external tools to remove the bolts. Hold the handle and turn the box door 151. The box door 151 will cause the positioning block 153 to slide outward in the positioning groove 155. Pull the box door 151 outward to make the limiting block 142 disengage from the limiting groove 144. A set of baffles 141 will disengage from the slot 143. After the rotating frame 131 is completely removed, use tools to remove the bolts on one side of the filter element 133. The filter element 133 can be taken out from the rotating frame 131 for replacement and maintenance, avoiding the need for complete replacement, which would affect production efficiency and reduce resource waste.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
