Description

Technical Field

[0001] The utility model relates to the technical field of paint filtering, in particular to a paint filtering device. Background Art

[0002] Water-based paints are divided into two categories: natural water-based paints made from natural substances or minerals and petrochemical water-based paints made from artificial synthetic resins. During the paint processing process, filtering equipment is needed to filter the paint for easy use. The paint is very easy to dry and is prone to clogging with small lumps and impurities inside.

[0003] For example, a filtering device for paint processing disclosed in publication number CN220736399U, in which a motor drives a transmission rod to rotate, and the transmission rod further drives a scraper and a friction brush to rotate, rubbing on the filter plate, and the friction brush brushes the paint into the filter plate, and then the scraper scrapes the lumps and stones into the discharge box.

[0004] However, when cleaning impurities, the filtering structure can only remove and filter some larger stones, etc., and cannot filter some solid particles produced by precipitation on the surface of the filter. These impurities accumulate for a long time and easily clog the mesh, thereby reducing the use effect of the device. In view of this, we propose a paint filtering device. Utility Model Content

[0014] Compared with the prior art, the utility model provides a coating filtering device, which has the following beneficial effects:

[0015] 1. The paint filtering equipment is equipped with a filtering structure to facilitate filtering of some solid particles inside the water-based paint. The paint is discharged through the liquid pump inside the feed pipe and the solid particles are filtered through the filter frame.

[0025] Specifically, the filtering structure 3 of the technical solution of the utility model includes: a filtering frame 31 , a rotating rod 32 , a reciprocating screw rod 33 , a sleeve 34 , blades 35 , a connecting block 36 , and a push plate 37 .

[0026] In one embodiment of the utility model, a filtering structure 3 is provided to facilitate filtering of some solid particles inside the water-based paint inside the inner tank 2. The inner tank 2 is provided to store the water-based paint, and a stirring structure is provided at the upper end of the paint box 1. The stirring structure is an existing conventional technology and is not described here. Two sets of feed ports are provided at the upper end of the paint box 1 to facilitate the user to add raw materials thereto. Electronic valves are provided on the surfaces of the feed pipe 5 and the discharge pipe 6 to control the switch for feeding.

[0027] When discharging the paint subsequently, the user can open the electronic valve at the discharge pipe 5 and start the liquid pump to work at the same time. At this time, the paint inside the inner tank 2 is discharged through the liquid pump inside the discharge pipe 5 and the solid particles are filtered through the filter frame 31. At this time, the rapid movement of the paint will drive the blade 35 to rotate, and the rotation of the blade 35 drives the rotating rod 32 on its surface to rotate, and the rotation of the rotating rod 32 drives the two sets of reciprocating screws 33 on its surface to rotate, and the rotation of the reciprocating screw 33 drives the sleeve 34 on its surface to reciprocate, and the movement of the sleeve 34 drives the connecting block 36 and the push plate 37 at its lower end to move to push the impurities, thereby preventing these impurities from accumulating for a long time and clogging the mesh at the filter frame 31, thereby improving the use effect of the device, and when the sleeve 34 moves, it will also drive the connecting rod 42 of its side wall to move, and the movement of the connecting rod 42 will drive the U-shaped cleaning plate 41 hinged to it to move up and down to clean the inner wall of the filter frame 31, thereby further improving the use effect of the device.

[0028] When the paint moves downward during use, the inclined guide frame 8 will be used to guide the paint. When the push plate 37 moves, the tamping plate 10 on its side wall will be driven to move. The movement of the tamping plate 10 will contact the baffle 9 and make it move. At this time, the push plate 37 will push some impurities into the collection box 11, and then the collection box 11 can be taken out for easy cleaning. At this time, some impurities will still remain on the inner surface of the filter frame 31. After a period of use, the filter frame 31 is detachably connected to the lower end side wall of the discharge pipe 5, so the user can take out the filter frame 31 as a whole.

[0029] Please continue reading Figure 1-Figure 6 The cleaning structure 4 includes a U-shaped cleaning plate 41 slidably connected to both sides of the inner wall of the filter frame 31, the upper end of the U-shaped cleaning plate 41 is hinged with one end of a connecting rod 42, and the other end of the connecting rod 42 is hinged to the side wall of the sleeve 34, and a storage groove 7 is provided at the lower end of the filter frame 31, and an inclined flow guide frame 8 is fixedly installed on the upper end of the filter frame 31, and baffles 9 are hinged on both sides of the lower end of the inclined flow guide frame 8, and a tamping plate 10 is fixedly installed on the side wall of the push plate 37.

A circular discharge port 12 is provided at the upper end of the filter frame 31 and is adapted to the diameter of the discharge pipe 5, and a liquid pump is arranged inside the discharge pipe 5.

[0030] During operation, the user can add raw materials into the inner tank 2 through the feed inlet, and when filtering the materials subsequently, the electronic valve at the feed pipe 5 can be opened and the liquid pump can be started to work. At this time, the paint inside the inner tank 2 is discharged through the liquid pump inside the feed pipe 5 and the solid particles are filtered through the filter frame 31. At this time, the rapid movement of the paint will drive the blades 35 to rotate, the rotation of the blades 35 drives the rotating rod 32 to rotate, the rotation of the rotating rod 32 drives the reciprocating screw rod 33 to rotate, the rotation of the reciprocating screw rod 33 drives the sleeve 34 to reciprocate, and the movement of the sleeve 34 drives the connecting block 36 and the push plate 37 to move. The push plate 37 pushes the impurities, and the movement of the sleeve 34 also drives the connecting rod 42 to move. The movement of the connecting rod 42 drives the U-shaped cleaning plate 41 to move up and down to clean the inner wall of the filter frame 31.
