When the filtering device 4 is in use, the paint mist first passes through the first arc-shaped filtering member composed of the first inner grid plate 42, the first filter cotton 43 and the first outer grid plate 44 to initially filter out larger particles of the paint mist. Then, the paint mist passes through the second arc-shaped filtering member composed of the second inner grid plate 45, the second filter cotton 46 and the second outer grid plate 47 to further filter out fine paint mist particles and improve the filtering effect.

[0019] The positioning device 1 includes a positioning box 11. Ventilation holes 12 are provided in the wall of the positioning box 11. A magnetic plate 13 is fixedly connected to the inner wall of the top of the positioning box 11. A triangular strip 14 is fixedly connected to the outer wall of the top of the positioning box 11. Limiting plates 16 are fixedly connected to both sides of the positioning box 11. A movable device 15 is slidably connected to the outer wall of the limiting plate 16. A cross-shaped block 5 is fixedly connected to the outer wall of the positioning box 11 through the ventilation holes 12. The outer wall inside the positioning box 11 is fixedly connected to the side wall of the insertion plate 41. The outer wall inside the positioning box 11 is fixedly connected to the side wall of the positioning plate 48. The outer wall of the positioning box 11 is fixedly connected to one end of the angle cushion block 2 away from the guiding strip 3.

[0020] The movable device 15 includes a sliding plate 151. A rotating rod 152 is rotatably connected to the inner wall of the sliding plate 151. Counterweight wheels 153 are fixedly connected to both ends of the rotating rod 152. A magnetic sheet 154 is fixedly connected to the bottom of the sliding plate 151. An inclined surface groove 155 is provided on the outer wall of the sliding plate 151 away from the magnetic sheet 154. The outer wall of the rotating rod 152 is slidably connected to the outer wall of the top end of the limiting plate 16. The outer wall of the sliding plate 151 is slidably connected to the outer wall of the positioning box 11. The outer wall of the sliding plate 151 is slidably connected to the outer wall of the triangular strip 14 through the inclined surface groove 155. The setting of the movable device 15 makes it easy to replace the first arc-shaped filter element and the second arc-shaped filter element. The sliding plate 151 slides along the limiting plate 16. When there is no external force to push the sliding plate 151, the inclined surface groove 155 contacts the triangular strip 14. At this time, due to the gravity of the counterweight wheel 153, the sliding plate 151 and the triangular strip 14 are closely attached. At the same time, the other end of the sliding plate 151 is fixed by the mutual attraction of the magnetic sheet 154 and the magnetic plate 13, thereby preventing gas leakage. When there is an external force to push the sliding plate 151, the triangular strip 14 will produce a guiding effect, causing the rotating rod 152 to disengage from the limiting plate 16.

[0021] Working principle:

[0022] During use, paint mist enters the interior of the positioning device 1 through the frame formed by the angle pad block 2 and the guiding strip 3. After passing through the filtering device 4, it then passes through the ventilation holes 12 in the positioning box 11 to ensure air circulation. The cross block 5 is used to distinguish the air inlet position and the air outlet position. When the filtering device 4 is in use, the paint mist first passes through the first arc-shaped filtering member composed of the first inner grid plate 42, the first filter cotton 43, and the first outer grid plate 44, preliminarily filtering out larger particles of paint mist. Then, the paint mist passes through the second arc-shaped filtering member composed of the second inner grid plate 45, the second filter cotton 46, and the second outer grid plate 47 to further filter fine paint mist particles and improve the filtering effect. The opening directions of the first arc-shaped filtering member and the second arc-shaped filtering member are the same, and arc-shaped filtering members with different diameters are used. This causes the airflow containing a large amount of undried spray paint mist to undergo high-speed bends with complex maze-like flow channels when flowing through the filtering assembly. Thus, under the combined action of centrifugal force, surface friction force, surface tension, and surface adsorption force, the undried spray paint mist in the airflow is trapped on the filtering assembly, and then gradually solidifies into a continuously thickening solid paint slag. These paint slags will grow and accumulate layer by layer in the vast space formed inside and between each filtering assembly. Moreover, the surface of each layer of the already solidified paint slag quickly transforms into a new paint mist trapping and growth substrate, thereby increasing its paint mist trapping ability. Since there is a wide paint mist accumulation and growth space inside and between each layer of the filtering assembly, this paint mist filter not only has a very small initial air resistance, but even after a long time of paint mist accumulation and growth, the increase in the air resistance of this paint mist filter is still very small. Furthermore, it ensures that this paint mist filter has a strong anti-saturation performance and can continuously maintain a high paint mist filtering and trapping ability. This enables the filtering device 4 to effectively filter and trap a large amount of undried spray paint mist contained in the exhaust systems of various dry spray paint booths. The above-mentioned paint mist filtering structure has a large number of layers, a long folding path, and a sufficient folding effect. It is not only applicable to large-scale paint mist but also has a high trapping efficiency for medium and small-scale paint mist. At the same time, because the air resistance is small, even during the process of the first arc-shaped filtering member and the second arc-shaped filtering member reaching saturation, the filtering efficiency will not rapidly decline, and the air resistance will not suddenly increase, improving the effective service life of the filter and reducing the replacement frequency of the filtering assembly.

[0023] The activity device 15 is arranged such that the first arc-shaped filter element and the second arc-shaped filter element are easy to replace. The sliding plate 151 slides along the limiting plate 16. When there is no external force pushing the sliding plate 151, the inclined surface groove 155 contacts the triangular strip 14. At this time, due to the gravity of the counterweight wheel 153, the sliding plate 151 and the triangular strip 14 are closely attached. At the same time, the other end of the sliding plate 151 is fixed by the magnetic attraction between the magnetic sheet 154 and the magnetic plate 13, thereby preventing gas leakage. When there is an external force pushing the sliding plate 151, the triangular strip 14 will play a guiding role, causing the rotating rod 152 to disengage from the limiting plate 16. The counterweight wheel 153 on the rotating rod 152 plays a role in balancing and stabilizing the movement of the sliding plate 151. After uncovering the sliding plate 151, the operator can pull out the first arc-shaped filter element composed of the first inner grid plate 42, the first filter cotton 43, and the first outer grid plate 44 and the second arc-shaped filter element composed of the second inner grid plate 45, the second filter cotton 46, and the second outer grid plate 47 from the positioning plate 48 and the insertion plate 41 from above, facilitating the replacement of the internal components of the filtering device 4.
