Description

Technical Field

[0001] This invention relates to the field of paint mist filter technology, specifically to a paint mist filter and its usage method. Background Technology

[0002] As is well known, in the field of industrial coating, the coating process generates paint mist containing liquid paint droplets, uncured resin, and solvent volatile carrier particles. If directly discharged or entering the downstream system, it can easily cause air pollution, block and corrode fans and pipes, and may also affect workshop air quality, operator health, and the quality of coated workpieces. Therefore, a key device, the paint mist filter, is needed. It can capture and separate paint mist particles through a specific structure to achieve the purpose of exhaust purification, protection of downstream equipment, improvement of coating quality, and reduction of pollution.

[0003] A search revealed a Chinese patent disclosure regarding a paint mist filter employing a textured filter cotton structure and its usage method, with application publication number CN118662994B. This patent includes a filter box with an inlet and an outlet. A first filter plate is fixedly installed inside the inlet. A filter assembly is installed inside the filter box, comprising filter cotton with a textured structure on the side near the inlet. The filter assembly also includes a negative pressure block installed inside the filter box, with the filter cotton positioned between the negative pressure block and the inlet; a movable plate installed on the side of the filter cotton near the inlet, one end of which is connected to the negative pressure block via a fixing rod, allowing the movable plate to move synchronously with the negative pressure block; and several one-way valves installed on the movable plate.

[0004] When filtering paint mist containing solvent volatile carrier particles, a special filter is used to intercept these particles, thus achieving the purpose of filtering the air containing paint mist. The problem with the existing technology is that, due to the lack of a structure to clean the solvent volatile carrier particles that accumulate on the filter screen surface after interception, the accumulated solvent volatile carrier particles on the filter screen surface will cause blockage, thereby reducing the efficiency of the filter screen in continuously filtering paint mist containing solvent volatile carrier particles. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a paint mist filter and its usage method, which has a structure that cleans solvent volatile carrier particles that accumulate on the filter screen surface after interception in real time. This allows for the real-time cleaning of solvent volatile carrier particles accumulated on the filter screen surface, thus preventing blockage caused by the accumulated solvent volatile carrier particles on the filter screen surface, thereby improving the filter screen's continuous filtration efficiency for paint mist containing solvent volatile carrier particles.

[0006] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: a paint mist filter, comprising an assembly mechanism and an mounting ring, wherein the mounting ring is disposed inside the assembly mechanism, a filter screen is disposed at the bottom of the mounting ring, a transmission rod is disposed on the surface of the filter screen, a recycling net is disposed at the bottom of the filter screen, and a vibration rod is disposed inside the mounting ring; the assembly mechanism comprises a flow guide hood, a flow deflector, and a mounting frame, wherein the flow deflector is disposed at the top of the flow guide hood, the mounting frame is disposed inside the flow deflector, the mounting ring is disposed inside the mounting frame, a flow guide plate is disposed inside the flow guide hood, and eight exhaust ports are disposed at the top of the flow guide plate.

[0007] By adopting the above technical solution, and by setting up an assembly mechanism, mounting ring, filter screen, transmission rod, recovery net, and vibration rod, the assembly mechanism, through the air guiding structure composed of the flow guide hood, the flow deflector, and the mounting frame, can guide air containing paint mist into the mounting frame when the flow deflector is installed at the exhaust port of the paint mist environment. When paint mist filtration is required, the paint mist filtration structure composed of the mounting ring, filter screen, transmission rod, recovery net, and vibration rod intercepts solvent volatile carrier particles in the paint mist. The vibration rod, along with the flowing air, strikes the filter screen, and the transmission rod evenly transmits the vibration generated by the strike to all parts of the filter screen, shaking the solvent volatile carrier particles filtered in the filter screen into the recovery net for collection, avoiding clogging and improving the efficiency of paint mist filtration.

[0008] The present invention is further configured such that: the drainage cover includes a positioning base, a positioning rod, and a drainage square tube, the positioning rod is bolted to the top of the positioning base, and the drainage square tube is bolted to the top of the positioning rod.

[0009] By adopting the above technical solution, by setting up a flow guide, the positioning base can form a structure that supports the flow guide with the positioning rod and the flow guide square tube. When the flow guide sends paint mist and air into the installation frame, the flow guide square tube can deliver the air to the flow guide plate and finally discharge it from the exhaust port, providing a guiding channel for the air flow.

[0010] The present invention is further configured such that: the flow guide includes an assembly flange plate, a flow guide square tube, and a mounting flange; the assembly flange plate is bolted to the top of the flow guide square tube; the flow guide square tube is welded to the inner side of the assembly flange plate; and the mounting flange is welded to the input end of the flow guide square tube on the side away from the flow guide square tube.

[0011] By adopting the above technical solution, by setting up a flow guide, the assembly flange plate can form an air conveying structure with the flow guide square tube and the mounting flange. When the mounting flange is connected to the paint mist conveying channel, the paint mist can be guided to the mounting frame through the flow guide square tube. Furthermore, the flow guide square tube can be disassembled from the flow guide square tube through the assembly flange plate, which facilitates the subsequent replacement of the mounting ring, filter screen, transmission rod, recycling net and vibration rod.

[0012] The present invention is further configured such that: the mounting frame includes a perforated plate, a limiting ring, and a mounting threaded ring; the top of the perforated plate is provided with eight holes; the perforated plate is welded to the top of the drainage square tube; the limiting ring is welded to the side of the top of the perforated plate near the holes; and the mounting threaded ring is welded to the inner side of the limiting ring.

[0013] By adopting the above technical solution, and by setting up an installation frame, the perforated plate can form a connection structure with the limiting ring and the installation threaded ring to limit the assembly threaded ring. The perforated plate can guide the air to the hole, and when the limiting ring limits the assembly threaded ring through the installation threaded ring, the assembly threaded ring is limited at the hole. This allows the air carrying paint mist to enter the assembly threaded ring in a concentrated manner, providing flowing air and paint mist for the subsequent filtration of paint mist by the filter screen.

[0014] The present invention is further configured such that: the mounting ring includes an assembly threaded ring, an assembly ring, and an assembly block, the assembly threaded ring is bolted to the inner side of the mounting threaded ring, the assembly ring is welded to the top of the assembly threaded ring, and the assembly block is welded to the inner side of the assembly ring.

[0015] By adopting the above technical solution, by setting an installation ring, the assembly threaded ring can form a temporary installation structure that limits the filter screen and vibration rod with the assembly ring and assembly block. The assembly threaded ring is threaded into the installation threaded ring. The installation corrugated ring can be limited in the assembly block by the limiting structure formed by the assembly ring and assembly block. The limitation of the support rod by the assembly threaded ring can facilitate the subsequent rotation of the rotating rod.

[0016] The present invention is further configured such that: the filter screen includes a mounting corrugated ring, a corrugated filter cotton plate, and a vibrating corrugated ring; the two mounting corrugated rings are respectively fixedly connected to the top and bottom of the corrugated filter cotton plate; the vibrating corrugated ring is fixedly connected to the inner side of the corrugated filter cotton plate away from the mounting corrugated ring; and the mounting corrugated ring is snapped into the inner side of the assembly block.

[0017] By adopting the above technical solution, a paint mist filtration structure can be formed by setting a filter screen and installing corrugated rings, corrugated filter cotton plates, and vibrating corrugated rings. The corrugated rings can provide stable support and limit the corrugated filter cotton plates by using assembly blocks and mounting blocks as support points. The corrugated filter cotton plates are existing filter cotton used for paint mist filtration and can filter paint mist in the air. The vibrating corrugated rings can vibrate by being struck by springs, thereby transmitting the vibration to the vibrating blocks.

[0018] The present invention is further configured such that: the transmission rod includes a vibrating block, a guide rod, and a transmission block; the vibrating block is welded to the surface of the vibrating corrugated ring; two guide rods are respectively fixedly connected to the top and bottom of the vibrating block; the transmission block is welded to the surface on which the corrugated ring is mounted; and the side of the transmission block closest to the vibrating block is fixedly connected to the guide rod.

[0019] By adopting the above technical solution, the vibrating block, guide rod, and transmission block can form a vibration transmission structure when the vibrating block is subjected to vibration transmitted by the vibrating corrugated ring. The guide rod can then transmit the vibration to the transmission block, which in turn transmits the vibration to each installed corrugated ring. By transmitting the vibration to the installed corrugated ring and the vibrating corrugated ring respectively, vibration can be transmitted to the corrugated filter cotton plate connected to it. The vibration shakes off the solvent volatile carrier particles accumulated by the filter cotton plate due to filtration, allowing the solvent volatile carrier particles to fall into the interception net bag for subsequent recycling.

[0020] The present invention is further configured such that: the recycling net includes an installation block, a threaded sleeve, and an interception net bag; the installation block is snapped into the bottom of the inner side of the installation corrugated ring; the threaded sleeve is welded to the surface of the installation block; and the interception net bag is threadedly connected to the surface of the threaded sleeve.

[0021] By adopting the above technical solution, the installation block, threaded sleeve, and interception net can form a structure for recovering solvent volatile carrier particles by setting up a recovery net. The installation block and the installation corrugated ring can limit the movement, thereby providing support and limiting for the threaded sleeve with the installation corrugated ring as the support point. The interception net is positioned directly below the corrugated filter cotton plate along with the threaded sleeve, which can stably and temporarily store the shaken-off solvent volatile carrier particles. The threaded sleeve can be detached from the installation block, which can facilitate the subsequent recovery of the solvent volatile carrier particles stored in the interception net.

[0022] The invention is further configured such that: the vibrating rod includes a support rod, a rotating rod, a fan blade, a positioning sleeve, a return torsion spring, and a spring plate; the support rod is welded to the inner side of the assembly threaded ring; the rotating rod is rotatably connected to the inner side of the support rod; the fan blade is welded to the surface of the rotating rod; the positioning sleeve is bolted to the side of the rotating rod surface away from the fan blade; the return torsion spring is welded to the right side of the inner side of the positioning sleeve; the spring plate is rotatably connected to the right side of the positioning sleeve; and the side of the spring plate near the positioning sleeve is welded to the side of the return torsion spring away from the positioning sleeve.

[0023] By adopting the above technical solution, a vibrating rod is set up. The support rod, together with the rotating rod, fan blade, positioning sleeve, return torsion spring, and spring, forms a structure that vibrates with the airflow. The rotating rod can rotate at the center of the corrugated filter cotton plate by being limited by the support rod. When the fan blade rotates with the thrust of the downward-flowing air, it can drive the rotating rod to rotate the positioning sleeve together. This allows the positioning sleeve to drive the spring to rotate together, so that the rotating spring continuously contacts the vibrating corrugated ring. Through the torque of the return torsion spring, the spring quickly returns to its original position after displacement upon contact with the vibrating corrugated ring, achieving the effect of the spring striking the vibrating corrugated ring. The purpose of generating vibration is achieved by using the spring to strike the vibrating corrugated ring.

[0024] A method for using a paint mist filter includes the following steps: S1. Installation process: First, the assembly block and assembly ring, which are equipped with filter screen, transmission rod, recycling screen and vibrating rod, are installed in each mounting threaded ring through the assembly threaded ring. When it is necessary to filter the paint mist, the mounting flange is installed at the output end of the paint mist conveying equipment with bolts. When the paint mist flows into the guide square tube with the air, the paint mist will flow into the mounting threaded ring through the holes on the perforated plate and finally into the assembly threaded ring. S2. Filtration and Recycling Process: First, when paint mist flows into the corrugated filter cotton plate through the assembled threaded ring, the air pushes the fan blades, causing the fan blades to rotate the rotating rod inside the support rod, and also causing the positioning sleeve to rotate the spring. After the spring contacts the vibrating corrugated ring, it is reset by the return torsion spring, causing the spring to strike the vibrating corrugated ring. The vibrating corrugated ring will vibrate after being struck, and the vibration will be transmitted to each guide rod through the vibrating block. Then, the guide rod will transmit the vibration to each installed corrugated ring through the transmission block, and finally to the corrugated filter cotton plate through the installed corrugated ring and the vibrating corrugated ring. When the corrugated filter cotton plate filters the paint mist in the air, the solvent volatile carrier particles will remain on the inner side of the corrugated filter cotton plate and begin to gradually... Due to the vibration of the corrugated filter cotton plate, the accumulated solvent volatile carrier particles will fall into the interception net bag for temporary collection until the current paint mist is filtered. When it is necessary to recover the solvent volatile carrier particles, remove the threaded sleeve from the mounting block, clean the interception net bag, and then reinstall it on the mounting block through the threaded sleeve. When it is necessary to replace and maintain the entire structure of the mounting ring, filter screen, transmission rod, recovery net, and vibrating rod, first remove the mounting flange from the paint mist conveying equipment, then remove the assembly flange plate from the diversion square tube, and finally remove the assembly threaded ring from the mounting threaded ring. Then, remove and replace the entire structure of the filter screen, transmission rod, recovery net, and vibrating rod connected to it.

[0025] (III) Beneficial Effects Compared with the prior art, the present invention provides a paint mist filter and its method of use, which has the following beneficial effects: This paint mist filter, through the assembly mechanism, allows the flow guide hood, mounting frame, guide plate, and exhaust port to form a structure for guiding air and paint mist. When the mounting flange is connected to the paint mist air conveying equipment, the equipment can deliver air and paint mist to the flow guide square tube. The air then enters the perforated plate through the flow guide square tube and flows into the assembly threaded ring, allowing the corrugated filter cotton plate to filter the paint mist. The unidirectional air conveying channel formed by the flow guide square tube, guide plate, and exhaust port allows the filtered air to be discharged through the exhaust port, achieving air circulation. Furthermore, the installation of the assembly flange plate and the flow guide square tube facilitates the disassembly and assembly of the flow guide square tube, which is beneficial for subsequent replacement of the mounting ring, filter screen, transmission rod, recycling net, and vibration rod. This paint mist filter, by incorporating an installation ring, filter screen, drive rod, recovery screen, and vibrating rod, forms a structure for filtering paint mist and recovering solvent volatile carrier particles. As paint mist passes through the corrugated filter cotton plate, both paint mist and solvent volatile carrier particles are intercepted on the inner wall of the plate. When it is necessary to recover the filtered solvent volatile carrier particles, the fan blades, driven by the flowing air, rotate the drive rod. This rotation causes the drive rod to rotate the positioning sleeve, which in turn rotates the spring. The spring, through the reset torsion spring, strikes the vibrating corrugated ring. The vibration is generated by impacting the corrugated ring, and the vibration is transmitted to the corrugated ring and corrugated filter cotton plate through the vibrating block, guide rod, and transmission block. Ultimately, the vibration shakes the solvent volatile carrier particles in the corrugated filter cotton plate to the interception net for collection. The interception net can be easily replaced and cleaned by disassembling it from the mounting block through the threaded sleeve, and the solvent volatile carrier particles can be recovered. At the same time, the installation threaded ring can be disassembled from the mounting threaded ring, which makes it easy to replace the entire structure of the mounting ring, filter screen, transmission rod, recovery net, and vibrating rod together.

[0028] 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.

[0029] Example 1 Please see Figure 1-4 A paint mist filter includes an assembly mechanism 1. The assembly mechanism 1 includes a flow guide hood 11, a flow deflector hood 12, and a mounting frame 13. The flow deflector hood 12 is located on top of the flow guide hood 11, and the mounting frame 13 is located inside the flow deflector hood 12. A mounting ring 2 is located inside the mounting frame 13. A flow guide plate 7 is provided on the inner side of the flow guide hood 11, and eight exhaust ports 8 are provided on the top of the flow guide plate 7. By setting the assembly mechanism 1, the flow guide hood 11, together with the flow deflector hood 12, the mounting frame 13, the flow guide plate 7, and the exhaust ports 8, can form a structure for guiding air and paint mist. When the mounting flange 123 is externally connected to a paint mist air conveying device, it can allow paint mist air to be conveyed. When the conveying equipment delivers air and paint mist to the guide tube 122, the air enters the perforated plate 131 through the guide tube 122 and flows into the assembly threaded ring 21 through the perforated plate 131, thereby allowing the corrugated filter cotton plate 32 to filter the paint mist. Through the one-way air delivery channel formed by the guide tube 113, the guide plate 7, and the exhaust port 8, the filtered air can be discharged through the exhaust port 8, realizing air circulation. Furthermore, the installation of the assembly flange plate 121 and the guide tube 113 facilitates the disassembly and assembly of the guide tube 122, which is beneficial for the subsequent replacement of the mounting ring 2, filter screen 3, transmission rod 4, recycling net 5, and vibration rod 6.

[0030] The flow guide hood 11 includes a positioning base 111, a positioning rod 112, and a flow guide square tube 113. The positioning rod 112 is bolted to the top of the positioning base 111, and the flow guide square tube 113 is bolted to the top of the positioning rod 112. By setting the flow guide hood 11, the positioning base 111, the positioning rod 112, and the flow guide square tube 113 can form a structure that supports the flow guide hood 12. When the flow guide hood 12 sends paint mist and air into the mounting frame 13, the flow guide square tube 113 can deliver the air to the guide plate 7 and finally discharge it from the exhaust port 8, providing a guiding channel for the flow of air.

[0031] The flow guide shroud 12 includes an assembly flange plate 121, a flow guide square tube 122, and a mounting flange 123. The assembly flange plate 121 is bolted to the top of the flow guide square tube 113. The flow guide square tube 122 is welded to the inner side of the assembly flange plate 121. The mounting flange 123 is welded to the input end of the flow guide square tube 122 away from the flow guide square tube 113. By setting the flow guide shroud 12, the assembly flange plate 121, the flow guide square tube 122, and the mounting flange 123 can form a structure for air delivery. When the mounting flange 123 is connected to the paint mist delivery channel, the paint mist can be guided to the mounting frame 13 through the flow guide square tube 122. The flow guide square tube 122 can be disassembled and reassembled from the flow guide square tube 113 through the assembly flange plate 121, which facilitates the subsequent replacement of the mounting ring 2, filter screen 3, transmission rod 4, recycling net 5, and vibration rod 6.

[0032] The mounting frame 13 includes a perforated plate 131, a limiting ring 132, and a mounting threaded ring 133. The top of the perforated plate 131 has eight holes. The perforated plate 131 is welded to the top of the drainage square tube 113. The limiting ring 132 is welded to the side of the top of the perforated plate 131 near the holes. The mounting threaded ring 133 is welded to the inner side of the limiting ring 132. By setting the mounting frame 13, the perforated plate 131, the limiting ring 132, and the mounting threaded ring 133 can form a connection structure that limits the assembly threaded ring 21. The perforated plate 131 can guide the air to the holes. When the limiting ring 132 limits the assembly threaded ring 21 through the mounting threaded ring 133, the assembly threaded ring 21 is limited at the holes. This allows the air carrying paint mist to enter the assembly threaded ring 21 in a concentrated manner, providing flowing air and paint mist for the subsequent filtration of paint mist by the filter screen 3.

[0033] The working principle of this embodiment is as follows: First, the assembly block 23 and assembly ring 22, which are equipped with filter screen 3, transmission rod 4, recycling screen 5 and vibration rod 6, are installed in each mounting threaded ring 133 through assembly threaded ring 21. When it is necessary to filter the paint mist, the mounting flange 123 is installed at the output end of the paint mist conveying equipment with bolts. When the paint mist flows into the guide square tube 122 with the air, the paint mist will flow into the mounting threaded ring 133 through the holes on the perforated plate 131, and finally flow into the assembly threaded ring 21.

[0034] Example 2 refer to Figure 5-9 A paint mist filter further includes an mounting ring 2, which is located inside the assembly mechanism 1. The bottom of the mounting ring 2 is provided with a filter screen 3, the surface of the filter screen 3 is provided with a transmission rod 4, the bottom of the filter screen 3 is provided with a recovery net 5, and the inner side of the mounting ring 2 is provided with a vibration rod 6. By configuring the mounting ring 2, filter screen 3, transmission rod 4, recovery net 5, and vibration rod 6, a structure for filtering paint mist and recovering solvent volatile carrier particles can be formed. As the paint mist passes through the corrugated filter cotton plate 32, the paint mist and solvent volatile carrier particles can be intercepted on the inner wall of the corrugated filter cotton plate 32. When it is necessary to recover the filtered solvent volatile carrier particles, the fan blade 63, driven by the flowing air, can rotate the rotating rod 62, thereby driving the rotating rod 62 to a fixed position. The sleeve 64 rotates the spring 66, causing the spring 66 to strike the vibrating corrugated ring 33 through the reset torsion spring 65. This causes the vibrating corrugated ring 33 to vibrate, and the vibration is transmitted through the vibration block 41 to the mounting corrugated ring 31 and the corrugated filter cotton plate 32 via the guide rod 42 and the transmission block 43. Ultimately, the vibration shakes the solvent volatile carrier particles in the corrugated filter cotton plate 32 to fall into the interception net bag 53 for recycling. The threaded sleeve 52 allows for easy disassembly and assembly from the mounting block 51, facilitating the replacement and cleaning of the interception net bag 53 and the recycling of solvent volatile carrier particles. At the same time, the assembly threaded ring 21 allows for disassembly and assembly from the mounting threaded ring 133, facilitating the replacement of the entire structure of the mounting ring 2, filter screen 3, transmission rod 4, recycling net 5, and vibration rod 6.

[0035] The mounting ring 2 includes an assembly threaded ring 21, an assembly ring 22, and an assembly block 23. The assembly threaded ring 21 is bolted to the inner side of the mounting threaded ring 133. The assembly ring 22 is welded to the top of the assembly threaded ring 21, and the assembly block 23 is welded to the inner side of the assembly ring 22. By setting the mounting ring 2, the assembly threaded ring 21, the assembly ring 22, and the assembly block 23 can form a temporary mounting structure for limiting the filter screen 3 and the vibrating rod 6. The assembly threaded ring 21 is threaded into the mounting threaded ring 133. The limiting structure formed by the assembly ring 22 and the assembly block 23 can limit the installation corrugated ring 31 within the assembly block 23. The limiting of the support rod 61 by the assembly threaded ring 21 can facilitate the subsequent rotation of the rotating rod 62.

[0036] The filter screen 3 includes a corrugated ring 31, a corrugated filter cotton plate 32, and a vibrating corrugated ring 33. The two corrugated rings 31 are fixedly connected to the top and bottom of the corrugated filter cotton plate 32, respectively. The vibrating corrugated ring 33 is fixedly connected to the inner side of the corrugated filter cotton plate 32 away from the corrugated rings 31. The corrugated rings 31 are snapped into the inner side of the assembly block 23. By setting the filter screen 3, the corrugated rings 31, together with the corrugated filter cotton plate 32 and the vibrating corrugated ring 33, can form a paint mist filtration structure. The corrugated rings 31 can provide stable support and limit for the corrugated filter cotton plate 32 by using the assembly block 23 and the mounting block 51 as support points. The corrugated filter cotton plate 32 is an existing filter cotton used for paint mist filtration, which can filter paint mist in the air. The vibrating corrugated ring 33 can vibrate by being struck by the spring 66, thereby transmitting the vibration to the vibrating block 41.

[0037] The transmission rod 4 includes a vibrating block 41, a guide rod 42, and a transmission block 43. The vibrating block 41 is welded to the surface of the vibrating corrugated ring 33. Two guide rods 42 are fixedly connected to the top and bottom of the vibrating block 41, respectively. The transmission block 43 is welded to the surface of the corrugated ring 31. The side of the transmission block 43 closest to the vibrating block 41 is fixedly connected to the guide rod 42. By setting the transmission rod 4, the vibrating block 41, the guide rod 42, and the transmission block 43 can form a vibration transmission structure. When the vibrating block 41 is subjected to vibration transmitted by the vibrating corrugated ring 33, the vibration can be transmitted to the transmission block 43 through the guide rod 42. The transmission block 43 can then further transmit the vibration to each corrugated ring 31. By transmitting the vibration to the corrugated ring 31 and the vibrating corrugated ring 33, vibration can be transmitted to the corrugated filter cotton plate 32 connected to it. The vibration shakes off the solvent volatile carrier particles accumulated by the corrugated filter cotton plate 32 due to filtration and interception, allowing the solvent volatile carrier particles to fall into the interception net bag 53 for subsequent recycling.

[0038] The recycling net 5 includes an installation block 51, a threaded sleeve 52, and an intercepting net bag 53. The installation block 51 is snapped into the bottom of the inner side of the installation corrugated ring 31. The threaded sleeve 52 is welded to the surface of the installation block 51. The intercepting net bag 53 is threadedly connected to the surface of the threaded sleeve 52. By setting up the recycling net 5, the installation block 51, the threaded sleeve 52, and the intercepting net bag 53 can form a structure for recycling solvent volatile carrier particles. The installation block 51 can be limited by the installation corrugated ring 31, thereby providing support and limitation for the threaded sleeve 52 with the installation corrugated ring 31 as the support point. The intercepting net bag 53 is positioned directly below the corrugated filter cotton plate 32 along with the threaded sleeve 52, which can stably and temporarily store the shaken-off solvent volatile carrier particles. The threaded sleeve 52 can be removed from the installation block 51, which can facilitate the subsequent recycling of the solvent volatile carrier particles stored in the intercepting net bag 53.

[0039] The vibrating rod 6 includes a support rod 61, a rotating rod 62, a fan blade 63, a positioning sleeve 64, a return torsion spring 65, and a spring plate 66. The support rod 61 is welded to the inner side of the assembly threaded ring 21. The rotating rod 62 is rotatably connected to the inner side of the support rod 61. The fan blade 63 is welded to the surface of the rotating rod 62. The positioning sleeve 64 is bolted to the side of the rotating rod 62 away from the fan blade 63. The return torsion spring 65 is welded to the right side of the inner side of the positioning sleeve 64. The spring plate 66 is rotatably connected to the right side of the positioning sleeve 64. The side of the spring plate 66 closest to the positioning sleeve 64 is welded to the side of the return torsion spring 65 away from the positioning sleeve 64. By setting the vibrating rod 6, the support rod 61 can be connected to the rotating rod 62, the fan blade 63, the positioning sleeve 64, the return torsion spring 65, and the spring plate 66. The plate 66 forms a structure that vibrates with the airflow. The rotating rod 62 can be limited by the support rod 61, allowing the rotating rod 62 to rotate at the center of the corrugated filter cotton plate 32. When the fan blade 63 rotates with the thrust of the downward-flowing air, it can drive the rotating rod 62 to rotate the positioning sleeve 64 together. This allows the positioning sleeve 64 to drive the spring plate 66 to rotate together, so that the rotating spring plate 66 continuously contacts the vibrating corrugated ring 33. Through the torque of the return torsion spring 65, the spring plate 66 quickly returns to its original position after displacement upon contact with the vibrating corrugated ring 33, achieving the effect of the spring plate 66 striking the vibrating corrugated ring 33. The purpose of generating vibration is achieved by using the spring plate 66 to strike the vibrating corrugated ring 33.

[0040] The working principle of this embodiment is as follows: First, when paint mist flows into the corrugated filter cotton plate 32 through the assembled threaded ring 21, the air will first push the fan blade 63, causing the fan blade 63 to drive the rotating rod 62 to rotate within the support rod 61, and also causing the positioning sleeve 64 to rotate the spring piece 66 together. After the spring piece 66 contacts the vibrating corrugated ring 33, it is reset by the return torsion spring 65, causing the spring piece 66 to strike the vibrating corrugated ring 33. The vibrating corrugated ring 33 will vibrate after being struck, and the vibration will be transmitted to each guide rod 42 through the vibrating block 41. Then, the guide rod 42 will transmit the vibration to each installed corrugated ring 31 through the transmission block 43. Finally, the vibration will be transmitted to the corrugated filter cotton plate 32 through the installed corrugated ring 31 and the vibrating corrugated ring 33. When the corrugated filter cotton plate 32 filters the paint mist in the air, the solvent volatile carrier particles will remain on the inner side of the corrugated filter cotton plate 32. The solvent volatiles begin to accumulate gradually. Due to the vibration of the corrugated filter cotton plate 32, the accumulated solvent volatiles carrier particles will fall into the interception net bag 53 for temporary collection until the current paint mist is filtered. When it is necessary to recover the solvent volatiles carrier particles, remove the threaded sleeve 52 from the mounting block 51, clean the interception net bag 53, and then reinstall it back into the mounting block 51 through the threaded sleeve 52. When it is necessary to replace and maintain the entire structure of the mounting ring 2, filter screen 3, transmission rod 4, recovery net 5, and vibration rod 6, first remove the mounting flange 123 from the paint mist conveying equipment, then remove the assembly flange plate 121 from the diversion square tube 113, and finally remove the assembly threaded ring 21 from the mounting threaded ring 133. Then, remove and replace the entire structure of the filter screen 3, transmission rod 4, recovery net 5, and vibration rod 6 connected to it.

10. A method of using a paint mist filter as described in any one of claims 1-9, characterized in that: Includes the following steps: S1. Installation process: First, the assembly block (23) and assembly ring (22) containing the filter screen (3), transmission rod (4), recycling screen (5) and vibration rod (6) are installed in each mounting threaded ring (133) through the assembly threaded ring (21). When it is necessary to filter the paint mist, the mounting flange (123) is installed at the output end of the paint mist conveying equipment with bolts. When the paint mist flows into the guide square tube (122) with the air, the paint mist will flow into the mounting threaded ring (133) through the hole on the perforated plate (131) and finally flow into the assembly threaded ring (21). S2. Filtration and Recycling Process: First, when the paint mist flows into the corrugated filter cotton plate (32) through the assembled threaded ring (21), the air will first push the fan blade (63), causing the fan blade (63) to drive the rotating rod (62) to rotate inside the support rod (61), and also causing the positioning sleeve (64) to rotate the spring piece (66) together. After the spring piece (66) contacts the vibrating corrugated ring (33), after being reset by the reset torsion spring (65), the spring piece (66) strikes the vibrating corrugated ring (33). When the vibrating corrugated ring (33) is struck, it vibrates and transmits the vibration to each guide rod (42) through the vibrating block (41). The guide rod (42) then transmits the vibration to each mounting corrugated ring (31) through the transmission block (43). Finally, the vibration is transmitted to the corrugated filter cotton plate (32) through the mounting corrugated ring (31) and the vibrating corrugated ring (33). When the corrugated filter cotton plate (32) filters the paint mist in the air, the solvent volatile carrier particles will remain on the inside of the corrugated filter cotton plate (32) and begin to accumulate. Due to the vibration of the corrugated filter cotton plate (32), the accumulated solvent volatile carrier particles will be vibrated and fall into the interception net bag (53) for temporary collection until the current paint mist is filtered. When it is necessary to recover the solvent volatile carrier particles, the threaded sleeve (52) is removed from the mounting block (51), the interception net bag (53) is cleaned, and then it is reinstalled back into the mounting block (51) through the threaded sleeve (52). When it is necessary to recover the mounting ring (2), the threaded sleeve (52) is removed from the mounting block (51), the threaded sleeve (52) is cleaned, and then the threaded sleeve (52) is reinstalled. When replacing and maintaining the entire structure of the filter screen (3), transmission rod (4), recycling net (5) and vibrating rod (6), first remove the mounting flange (123) from the paint mist conveying equipment, then remove the assembly flange plate (121) from the diversion square tube (113), and finally remove the assembly threaded ring (21) from the mounting threaded ring (133). Then, remove and replace the entire structure of the filter screen (3), transmission rod (4), recycling net (5) and vibrating rod (6) connected to it.
