DETAILED DESCRIPTION

[0022] As shown in Figure 1 , 2 , an automatic feeding filter device for water-based paint comprises a processing cylinder 10, the top of the processing cylinder 10 is fixedly connected with a feeding pipe 11, the top of the feeding pipe 11 is fixedly connected with a discharge port of a drawing cylinder, the drawing cylinder is lifted above the processing cylinder 10 through a supporting frame or a lifting device, and a first valve 14 is installed on the feeding pipe 11; the bottom of the processing cylinder 10 is provided with a filter screen 12, and the bottom of the processing cylinder 10 is placed with a receiving cylinder 13.

[0023] Preferably, the top of the filter screen 12 is fixedly connected with a connecting ring 26, the inner side of the connecting ring 26 is provided with a second threaded groove 27; the outer side of the bottom of the processing cylinder 10 is provided with a first threaded groove 25. In use, the filter screen 12 is fixed at the bottom of the processing cylinder 10 by screwing the second threaded groove 27 inside the connecting ring 26 with the first threaded groove 25, which can facilitate the replacement of the filter screen 12.

[0024] With reference to Figure 1 、 2 The top of the processing cylinder 10 is provided with a pressurizing mechanism, which comprises a connecting pipe 20 fixedly communicated with the left side of the top of the processing cylinder 10, a connecting head 21 fixedly connected with the top of the connecting pipe 20, an air charging pipe 22 inserted into the top of the connecting head 21, and the other end of the air charging pipe 22 is fixedly connected with the output end of an air pump.

[0025] Preferably, the right side of the top of the processing cylinder 10 is fixedly communicated with a discharge pipe 23, and the outer side of the discharge pipe 23 is provided with a second valve 24. In use, the first valve 14 is opened, so that the water-based paint in the cylinder is drawn into the inside of the processing cylinder 10 through the feeding pipe 11, and the water-based paint is filtered by the filter screen 12 and then enters the inside of the receiving cylinder 13. Since the water-based paint is relatively viscous and the filter screen 12 used has a relatively small aperture, the filtering speed of the water-based paint is relatively slow. In order to improve the filtering speed of the water-based paint, the air pump can be turned on to suck in the external air through the input end of the air pump, and then the air is discharged into the inside of the processing cylinder 10 through the air charging pipe 22. Since the space inside the processing cylinder 10 is limited, the excess gas can extrude the water-based paint on the surface of the filter screen 12, so that the water-based paint can quickly pass through the filter screen 12, thereby achieving the effect of accelerating the filtering speed of the water-based paint. At the same time, after the water-based paint on the surface of the filter screen 12 is filtered, the inside of the processing cylinder 10 is not in a sealed state, so the water-based paint in the cylinder automatically flows to the processing cylinder 10, achieving the effect of automatic feeding of the water-based paint. If the discharging speed of the cylinder is too fast, the water-based paint in the processing cylinder 10 can form a negative pressure, at which time the first valve 14 should be closed and the second valve 24 should be opened, so that the external air enters, allowing the water-based paint to be quickly filtered out of the processing cylinder 10, and then the discharging speed of the cylinder can be appropriately reduced to form a continuous filtering.

[0026] With reference to Figure 1 、 3The outer side of the processing cylinder 10 is provided with a supporting mechanism 30, which comprises a set of fixed frames 301 fixedly connected to the outer side of the processing cylinder 10 in a circumferential arrangement, the left and right sides of the inner side of the fixed frame 301 are jointly rotatably connected with rotating rods 302, and the outer side of the rotating rod 302 is fixedly connected with supporting rods 303; the left and right sides of the supporting rod 303 are respectively provided with positioning grooves 307, and the inner side of the positioning groove 307 is slidably connected with an insertion block 308; and the left and right sides of the inner side of the fixed frame 301 are respectively provided with insertion grooves 306.

In use, the rotating rod 302 and the supporting rod 303 are supported by the elastic force of the volute spring 305, so that the supporting rod 303 remains in a vertical state, so that the supporting mechanism 30 does not occupy too much space when not in use,

[0028] Specifically, referring to Figure 4 The inner side of the insertion block 308 is fixedly connected with a supporting spring 309, the right side of the supporting spring 309 is fixedly connected with the positioning groove 307, the inner side of the insertion block 308 is provided with a guide groove 310, the inner side of the guide groove 310 is slidably connected with a guide rod 311, and the guide rod 311 is fixedly connected with the positioning groove 307.

[0029] Preferably, referring to Figure 4 The outer side of the insertion block 308 is gradually shortened in an arc shape from top to bottom; in the initial state, the four side supporting rods 303 are in a vertical state, the insertion block 308 is submerged in the positioning groove 307 to compress the supporting spring 309, and the inner side surface of the insertion block 308 is in contact with the fixed frame 301; when it is needed to place the processing cylinder 10 on the top of the receiving cylinder 13, the supporting rod 303 is turned outward, the volute spring 305 is deformed, until the supporting rod 303 is turned by 90 degrees to make the insertion block 308 correspond to the position of the insertion groove 306, so that the supporting spring 309 rebounds to drive the insertion block 308 to be inserted into the inner side of the insertion groove 306, thereby achieving the positioning effect of the supporting rod 303; the four side supporting rods 303 are unfolded and placed on the top of the receiving cylinder 13, so that the supporting effect of the processing cylinder 10 can be achieved, and the supporting mechanism 30 is foldable, small in size, easy to open, and convenient for replacing the processing cylinder 10 and carrying and moving.

[0031] The working principle of the utility model is: when using, open the first valve 14, so that the water-based paint in the cylinder is drawn into the inside of the processing cylinder 10 through the feed pipe 11, and the water-based paint is filtered through the filter screen 12 and then enters the inside of the receiving cylinder 13; because the water-based paint is relatively viscous, and the filter screen 12 used has a relatively fine aperture, the filtering speed of the water-based paint is relatively slow, in order to improve the filtering speed of the water-based paint, the air pump can be opened, the air pump input end draws in external air and then discharges the air into the inside of the processing cylinder 10 through the inflation pipe 22, because the air enters the processing cylinder 10 and the space inside the processing cylinder 10 is limited, the excess gas extrudes the water-based paint on the surface of the filter screen 12, so that the water-based paint rapidly passes through the filter screen 12, thereby achieving the effect of accelerating the filtering speed of the water-based paint; and if the cylinder discharging speed is too fast, the water paint is easy to form negative pressure in the processing cylinder 10, at this time, the first valve 14 should be closed and the second valve 24 should be opened, so that external air enters, the water paint is rapidly filtered out of the processing cylinder 10, and then the cylinder discharging speed is appropriately reduced, so that continuous filtering is formed.
