Description

Technical Field

[0001] This utility model relates to the field of filtration mechanism technology, and more specifically, to a filtration mechanism for a paint spraying booth. Background Technology

[0002] A spray painting booth is a room where the surface of an object is sprayed with paint and then dried. The painted object not only looks better, but also has a certain degree of protection.

[0003] After the spray painting and baking booth operation is completed, a certain amount of wastewater is generated. This wastewater usually contains paint, which is insoluble in water and floats on the surface, easily clogging pipes and impacting the environment. It needs to be treated. The existing treatment measures use scrapers to scrape off the paint floating on the water surface. However, most of them use unidirectional scraping, which can easily push the paint to the side that cannot be scraped when returning to the position, thus affecting the overall filtration effect. At the same time, the structure is fixed and can only treat the paint in the corresponding liquid level, which is not very practical and the overall use effect is not ideal.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a filtration mechanism for a paint spraying booth, which has the advantages of reciprocating slag removal, good slag removal effect, and adaptive slag removal, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the advantages of reciprocating slag removal, good slag removal effect, and adaptive slag removal, the specific technical solution adopted by this utility model is as follows:

[0009] A filtration mechanism for a spray painting booth includes a filter box and a motor. Fixed boxes are symmetrically installed on both sides of the bottom of the filter box. A baffle is slidably connected inside the fixed box. An electric hydraulic rod is connected to the bottom of the baffle inside the fixed box. A filter plate is fixedly installed on the top of one side of the baffle. Several sets of filter holes are evenly distributed on the surface of the filter plate. A lead screw is installed at the middle of the top of the filter box. One end of the lead screw passes through one side of the filter box and is connected to the motor. A movable seat is sleeved around the lead screw. An adjusting box is fixedly installed at the bottom of the movable seat. A slag discharge plate is slidably connected inside the adjusting box. A spring is installed on the top of the slag discharge plate inside the adjusting box. Floats are symmetrically installed on the bottom of both sides of the slag discharge plate.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a filtration mechanism for a spray painting booth, which has the following beneficial effects:

[0019] This invention employs a float, an electric hydraulic rod, and a filter plate. After the waste liquid from the spray painting booth is introduced into the filter box, the level gauge detects the liquid level and causes the electric hydraulic rod to move up and down accordingly. This allows the baffle to move up and down to adapt to the height of the waste liquid. Simultaneously, the float continuously floats on the liquid surface, causing the slag discharge plate to adjust accordingly, enabling it to handle waste liquid at different heights and expanding the applicability of the device. A lead screw drives the slag discharge plate to reciprocate, pushing the paint to both sides, preventing localized paint accumulation and reduced slag discharge quality caused by unilateral processing. Furthermore, the flexible plate pushes the waste liquid and paint onto the filter plate, allowing the waste liquid to be discharged through the surface filter holes, ensuring more thorough paint removal and improving processing quality. It features reciprocating slag removal, good slag removal effect, and self-adaptive slag removal. Attached Figure Description

[0028] According to an embodiment of the present invention, a filtration mechanism for a spray painting booth is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a filtration mechanism for a spray booth according to an embodiment of the present invention includes a filter box 1 and a motor 16. Fixed boxes 18 are symmetrically installed on both sides of the bottom of the filter box 1. A baffle 17 is slidably connected inside the fixed box 18. An electric hydraulic rod 19 is connected to the bottom of the baffle 17 inside the fixed box 18. A filter plate 15 is fixedly installed at the top of one side of the baffle 17. Several sets of filter holes 14 are evenly distributed on the surface of the filter plate 15. A lead screw 8 is installed at the middle of the top of the filter box 1. One end of the lead screw 8 passes through one side of the filter box 1 and is connected to the motor 16. A movable seat 10 is sleeved around the outer periphery of the lead screw 8. An adjustment box is fixedly installed at the bottom of the movable seat 10. 12. A slag discharge plate 13 is slidably connected inside the regulating box 12. A spring 11 is installed on the top of the slag discharge plate 13 inside the regulating box 12. Floats 9 are symmetrically installed on the bottom of both sides of the slag discharge plate 13. A flexible plate 4 is installed at the bottom of the slag discharge plate 13. The flexible plate 4 is made of flexible material, so it can penetrate into the waste liquid and move continuously on the filter plate 15 through compression deformation, thereby pushing the waste liquid and paint simultaneously, so that the paint can be removed more thoroughly. Similarly, the slag discharge plate 13 can adjust its structural height through the deformation of the spring 11, which is convenient for better use, adapts to the processing operation of different liquid levels, and expands the applicability of the device.

[0030] In one embodiment, a collection box 7 is installed on one side of the baffle 17. The collection box 7 is provided to collect the processed waste for subsequent processing.

[0031] In one embodiment, a water inlet pipe 3 is installed at the top center of one side surface of the filter box 1. The water inlet pipe 3 is designed to introduce the waste liquid generated by the paint spraying booth, so as to facilitate the subsequent treatment of the paint in the waste liquid.

[0032] In one embodiment, a water guide plate 2 is installed at an angle in the middle of the bottom of the filter box 1. The water guide plate 2 is designed to discharge the waste liquid more fully and improve the overall drainage effect.

[0033] In one embodiment, a water outlet pipe 5 is installed at the lowest end of the water guide plate 2 on the surface of the filter plate 15. The water outlet pipe 5 is provided for discharging the treated waste liquid.

[0034] In one embodiment, a level gauge 6 is installed inside the filter box 1. The level gauge 6 is set up to detect the level of waste liquid and adjust the electric hydraulic rod 19 according to the detected level, so that the height of the baffle 17 changes, which can continuously block waste liquid at different levels and improve the practicality of the device.

[0035] In one embodiment, a guide groove is provided at the top of the filter box 1. The guide groove is provided to limit the movement of the movable seat 10, ensuring that it can reciprocate under the rotation of the lead screw 8, thereby achieving stable operation.

[0036] In one embodiment, a controller is provided on one side of the filter box 1. The controller is set up to control the motor 16, level gauge 6, electric hydraulic rod 19 and other equipment. Since there are various types of controllers and the application technology is mature, personnel can select one according to their needs and implement control through programming. Therefore, it will not be described in detail.

[0037] Working Principle: In actual use, the waste liquid discharged from the spray booth is introduced through the inlet pipe 3, and the treated waste liquid can be discharged through the outlet pipe 5 at the bottom, realizing a complete filtration operation. After the waste liquid is introduced, the liquid level is detected by the level gauge 6, and the electric hydraulic rod 19 is controlled according to the different liquid levels, thereby adjusting the height of the baffle 17 so that the baffle 17 can effectively block the waste liquid. At the same time, as the liquid level changes, the float 9 can drive the slag discharge plate 13 to move. The corresponding up-and-down movement allows the slag discharge plate 13 to continuously contact the paint on the liquid surface. Then, the operation of the motor 16 drives the lead screw 8 to reciprocate, causing the moving seat 10 to reciprocate, which in turn moves the slag discharge plate 13 reciprocally on the liquid surface. This movement of the slag discharge plate 13 scrapes the paint onto one side of the baffle 17, preventing paint blockage in the pipes. Since the collection boxes 7 are symmetrically arranged on both sides, the reciprocating movement effectively pushes the paint to both sides, preventing unidirectional movement from causing some paint to remain unprocessed and resulting in blockages. The paint accumulates, thus improving the overall slag removal effect. Furthermore, when pushing the paint, the flexible plate 4 can push some of the waste liquid along the filter plate 15. At this time, the waste liquid will move the paint on its surface synchronously. The filter plate 15 has filter holes 14 on its surface, which can filter out the waste liquid, preventing it from entering the collection box 7 and affecting the overall slag removal effect. The mesh size of the filter holes 14 can be selected according to the type of paint being processed (e.g., 30-50 mesh (pore size 595-300μm)). The system intercepts paint residue clumps left by the spray gun and captures resin condensates with a diameter >300μm; 150-200 mesh (pore size 100-75μm) removes atomized paint droplets (typical particle size 80-150μm) and retains uncured paint film fragments; 400-500 mesh (pore size 38-25μm) targets nano-sized emulsion particles of water-based paints, preventing paint from falling back through the filter holes 14, thus ensuring the overall slag removal quality and facilitating better use. The device as a whole has the advantages of reciprocating slag removal, good slag removal effect, and adaptive slag removal.
