Description

Technical Field

[0001] This invention relates to the technical field of separation and filtration equipment for coatings, specifically to a separation and filtration device for environmentally friendly, low-naphthalene aromatic solvents used in coatings. Background Technology

[0002] Water-based coatings are coatings that use water as a diluent and do not contain organic solvents. They produce a full, clear, and flexible film, and are characterized by water resistance, abrasion resistance, aging resistance, yellowing resistance, fast drying, and ease of use. They are mostly used on materials such as metals, furniture, plastics, and glass. The production process generally involves adding powders such as calcium carbonate, talc, color powder, and titanium dioxide to a water-based solvent, followed by grinding and filtration.

[0003] Application number CN202323127286.3 discloses a separation and filtration device for water-based coating processing. The coating flows sequentially through the filter holes in a vortex vane, and is filtered again by the bottom vane. The separated coating is then sprayed at high speed by a booster pump onto a filter basket. The coating is then extruded through the filter screen under high pressure to remove impurities. The filtered coating flows to the bottom of the casing, which is made entirely of stainless steel. The bottom sidewall where the coating is stored is smooth, facilitating coating output and preventing residue. A cleaning mechanism is located on the side wall of the casing, with high-pressure water sprayers on all four sides to clean the filter basket. The wastewater from the cleaning process is discharged through a drain pipe. The overall dual-sided material conveying method significantly improves the coating filtration efficiency. The cleaning mechanism within the casing automatically cleans the filter basket, reducing manual labor. The filter basket is fixed to the bottom of the separation tank, which is moved up and down by a lifting mechanism, allowing for more comprehensive cleaning of the filter basket, resulting in higher cleaning efficiency and greater reliability.

[0004] The separation and filtration device for water-based coating processing disclosed in the above patent cannot automatically discharge solid waste trapped in the filter basket. It requires manual removal by staff, which is very troublesome. Moreover, after removal, the inner wall of the filter basket is still covered with dirt that clogs the mesh, requiring staff to manually clean it out and unclog the mesh. Summary of the Invention

[0005] The purpose of this invention is to provide a separation and filtration device for environmentally friendly, low-naphthalene aromatic solvents used in coatings. After filtration, the device can lift the tail of the separation filter housing by winding a steel rope using a winding assembly, allowing the trapped debris inside the filter cylinder to be quickly poured out. This facilitates automated waste removal, saves manpower, and can be combined with a liftable L-shaped long brush to brush off dirt from the inner wall of the filter cylinder, which then falls out under its own weight. Furthermore, the bottom of the separation filter housing is mounted on the top of a liftable movable support arc, allowing it to remain stably at various angles, thus solving the problems mentioned in the background art.

[0022] In this solution, during use, the environmentally friendly low-naphthalene aromatic solvent separation and filtration equipment for coatings disclosed in this invention can lift the tail of the separation filter shell 7 by winding the steel rope 20 through the winding assembly after filtration, so that the debris trapped in the filter cylinder 14 can be quickly poured out, facilitating automated emptying of debris, saving manpower, and can be used with the liftable L-shaped long brush 23 to brush off the dirt on the inner wall of the filter cylinder 14 and then fall out under its own gravity. The bottom end of the separation filter shell 7 is mounted on the top of the liftable movable support arc strip 32, which can make it stably stay at various angles. When it is necessary to empty the filter, When the garbage trapped inside the drum 14 is released, the door 16 is opened, and the external power supply activates the first motor 5 and the first electric telescopic rod 12 via an external switch. Simultaneously, the third motor 30 is controlled to rotate forward, and the first electric telescopic rod 12 is controlled to shorten. Then, the first motor 5 is controlled to rotate forward, causing the first electric telescopic rod 12 to shorten and move the rack 11 away from the gear 10, releasing the self-locking mechanism. At the same time, the third motor 30 rotates forward, causing the threaded screw 28 to rotate clockwise. Through the screw sleeve 29, the slide rod 25 slides downward along the inner wall of the slide groove 24. The movable support arc strip 32 moves downward smoothly in sync. Simultaneously, the first motor 5 drives the take-up roller 1... 3. Rotate the winding steel rope 20 clockwise. The filter shell 7 is lifted with the hinge bolt 6 as the center of rotation. It is then stably stopped at the current tilt angle under the support of the movable support arc 32. At this time, the external power supply controls the second electric telescopic rod 21 to shorten through the external switch, so that the bristles of the L-shaped long brush 23 are in close contact with the inner wall of the filter cylinder 14. The second motor 8 is controlled to drive the filter cylinder 14 to rotate at high speed through the connecting rod 15. The fixed L-shaped long brush 23 continuously brushes off the dirt on the inner wall of the filter cylinder 14 and unclogs the mesh. The garbage trapped in the filter cylinder 14 and the garbage brushed off by the L-shaped long brush 23 are separated by their own weight. Under the action of the filter cylinder 14, it automatically slides out and cleans the internal debris. After cleaning, the first motor 5 is reversed to make the tail of the separation filter shell 7 fall back onto the support fork 9. Then, the first electric telescopic rod 12 is extended to make the rack 11 lock the main gear 10. The third motor 30 is reversed to make the movable support arc strip 32 move upward and reset to continue supporting. Finally, the second electric telescopic rod 21 is extended to make the L-shaped long brush 23 move away from the inner wall of the filter cylinder 14 so as not to hinder its high-speed rotation during operation (the first motor 5, the second motor 8, the first electric telescopic rod 12 and the suction pump 3 are all existing products on the market).
