[0024] like Figure 2 As shown, the present invention proposes a pigment impurity filtering device. Compared with the first embodiment, the present embodiment records the detailed structure of the extrusion assembly. The extrusion assembly includes a telescopic device 4 and a pressure plate 5. The telescopic device 4 is connected to the filter box 1; the telescopic device 4 is selected from but not limited to a hydraulic cylinder; the pressure plate 5 is connected to the telescopic end of the telescopic device 4, and a sealing gasket 6 is connected to the outer peripheral surface of the pressure plate 5; the sealing gasket 6 is selected from but not limited to a rubber layer.

[0025] Example 3

[0026] like Figure 2-Figure 4 As shown, the present invention proposes a pigment impurity filtering device. Compared with the second embodiment, this embodiment describes the detailed structure of the coarse filter assembly and the fine filter assembly. The coarse filter assembly includes a support plate 7, a limit plate 8 and a first filter screen 9. The support plate 7 is connected to the filter box 1 and has an opening.

[0027] The limiting plates 8 are evenly distributed on the circumference and are provided with slots;

[0028] The first filter screen 9 is slidably connected in the slot on the limiting plate 8 .

[0029] The fine filter assembly includes a fixed cylinder 10, a fixed plate 11, a movable plate 12, and a buffer assembly. The fixed cylinder 10 is connected to the opening on the support plate 7. The fixed cylinder 10 is a hollow structure. The fixed plate 11 is detachably connected to the fixed cylinder 10. A plurality of needles are connected to the fixed plate 11. The needles fit into the mesh of the second filter 13 on the movable plate 12.

[0030] The fixed plate 11 is connected to dovetail blocks 16 distributed around the circumference, and the dovetail blocks 16 are slidably connected to dovetail grooves 17 provided on the inner wall of the fixed cylinder 10;

[0031] The movable plate 12 is arranged parallel to the fixed plate 11. The fixed plate 11 is provided with a through hole connected to the second filter screen 13. The mesh size of the second filter screen 13 is larger than that of the first filter screen 9.

[0032] The buffer assembly is connected to the fixed plate 11 and the movable plate 12; when the buffer assembly is in use, the buffer assembly drives the movable plate 12 to move closer to the fixed plate 11 to reduce the water pressure.

[0033] The buffer assembly includes a guide rod 14 and an elastic member 15. The guide rods 14 are distributed around the fixed cylinder 10. The guide rods 14 are connected to the fixed plate 11. The top of the guide rod 14 is slidably connected to the through hole opened on the movable plate 12. The elastic member 15 is sleeved on the outside of the guide rod 14.

At this time, the telescopic device 4 is started, and the output end of the telescopic device 4 drives the pressure plate 5 to move along the central axis of the filter box 1. When the pressure plate 5 is pressed down, the liquid pigment in the fixed cylinder 10 is accelerated to pass through the second filter screen 13 connected to the movable plate 12. After the liquid is filtered, it falls Above the guide plate 18, when the valve on the discharge pipe 3 is opened, the guide plate 18 can be used to guide the filter 9 so that it is discharged from the discharge pipe 3 and enters the next process. When the surface of the first filter screen 9 is clogged with impurities and the filtering effect becomes poor, the first filter screen 9 can be directly pulled upward to keep it away from the limit plate 8 and directly removed for cleaning. When the mesh holes on the surface of the second filter screen 13 are more clogged, the water pressure will push the movable plate 12 and the second filter screen 13 down, and the second filter screen 13 will contact the needle on the fixed plate 11 to perform a certain degree of dredging to prevent the water pressure from causing deformation and damage to the second filter screen 13. After the filtration is completed, the guide rod 14 can be pulled out to remove the movable plate 12 and the fixed plate 11 for maintenance.

Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
