[0021] In order to more clearly explain the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the drawings in the specification.

[0022] As Figures 1 to 4 shown, the embodiment of the present invention proposes a screen device for a sand mill that facilitates discharging, including a base 1. A support plate 2 is provided on the upper surface of the base 1. A grinding cylinder 3 is fixedly connected to the upper surface of the support plate 2. A material inlet 4 and a grinding medium inlet 5 are provided on the grinding cylinder 3. A filter plate 6 is provided on one side of the grinding cylinder 3. A housing 7 is fixedly connected to the upper surface of the base 1. A mounting frame 8 is fixedly connected to the housing 7. A lifting and lowering assembly 9 is provided between the housing 7 and the support plate 2. A fixed plate 15 is fixedly connected to the lower surface of the support plate 2. The fixed plate 15 is rotatably connected to the mounting frame 8. The grinding medium enters the grinding cylinder 3 through the grinding medium inlet 5, and the grinding material enters the grinding cylinder 3 through the material inlet 4. The grinding medium grinds the material. The aperture size of the filter plate 6 is larger than the powder of the crushed material and smaller than the grinding medium, so that the material powder passing through the filter plate 6 in the grinding cylinder 3 meets the requirements. During the grinding process, continuous material passes through the filter plate 6 for discharging. After a period of time, at this time, the lifting and lowering assembly 9 drives the support plate 2 and the grinding cylinder 3 to rotate and tilt together. The material and the grinding medium gather on one side of the filter plate 6. Along with the stirring of the stirring assembly 10, it promotes the remaining material in the grinding cylinder 3 to flow out of the grinding cylinder 3, which is beneficial to reducing residues and facilitating discharging.

[0023] Specifically, the lifting and lowering assembly 9 includes a horizontal plate 91. The horizontal plate 91 is fixedly connected to the housing 7. An electric push rod 92 is fixedly connected to the lower surface of the horizontal plate 91. A guide rail 93 is fixedly connected to the lower surface of the support plate 2. A sliding seat 94 is slidably connected in the guide rail 93. The sliding seat 94 is hinged to the telescopic rod of the electric push rod 92. The electric push rod 92 pushes the sliding seat 94 to make the sliding seat 94 slide on the guide rail 93, and one side of the support plate 2 is pushed up, so that the support plate 2 deflects and tilts to promote discharging.

[0024] Specifically, a stirring assembly 10 is provided inside the grinding cylinder 3. The stirring assembly 10 includes a vertical plate 101. The vertical plate 101 is fixedly connected to the support plate 2. A driving motor 102 is fixedly connected to one side of the vertical plate 101. A rotating rod 103 is rotatably connected inside the grinding cylinder 3. A plurality of stirring rods 104 are fixedly connected to the outer side of the rotating rod 103. The main shaft of the driving motor 102 is fixedly connected to the rotating rod 103. The driving motor 102 drives the rotating rod 103 to rotate, and the rotating rod 103 drives all the stirring rods 104 to stir the grinding medium and the material, improving the grinding effect of the grinding medium on the material and being beneficial to improving the grinding effect.

[0025] Specifically, the filter plate 6 is rotatably connected to the grinding cylinder 3, and the rotating rod 103 is fixedly connected to the filter plate 6. When the driving motor 102 drives the rotating rod 103 to rotate, the rotating rod 103 drives the filter plate 6 to rotate. Since the grinding medium and the material are located below the inside of the grinding cylinder 3 and contact the lower half of the filter plate 6, when discharging, the filter plate 6 rotates, and the position where there is no contact with the material is constantly changing, which can prevent the filter plate 6 from being blocked due to continuous contact with the material at the same position.

[0026] Specifically, a support plate 14 is fixedly connected to the inner wall of the grinding cylinder 3. A ventilation pipe 11 is fixedly connected to the support plate 14. One end of the ventilation pipe 11 is fixedly connected to a square nozzle 12. The square nozzle 12 is closely attached to one side of the filter plate 6. The other end of the ventilation pipe 11 is communicated with a blower. There is air blown by the blower inside the square nozzle 12. The square nozzle 12 faces the filter plate 6, and the air blows the material remaining and stuck on the filter plate 6 to clean the filter plate 6. The material falls back into the grinding cylinder 3 and passes through the filter plate 6 again. As the filter plate 6 rotates, the blowing position of the square nozzle 12 on the filter plate 6 changes. The square nozzle 12 can clean each position of the filter plate 6 to prevent the filter plate 6 from being blocked and affecting the discharging.

[0027] Specifically, the square nozzle 12 is closely attached to the upper half of the filter plate 6. The grinding medium and the material are located below the inside of the grinding cylinder 3 and contact the lower half of the filter plate 6. When the square nozzle 12 cleans the filter plate 6, it will not affect the discharging, and the two operations are carried out simultaneously, saving time.

[0028] Working principle: The grinding medium enters the grinding cylinder 3 through the grinding medium inlet 5, and the grinding material enters the grinding cylinder 3 through the material inlet 4. The driving motor 102 drives the rotating rod 103 to rotate, and the rotating rod 103 drives all the stirring rods 104 to stir the grinding medium and the material. The grinding medium grinds the material. Continuously, the material passes through the filter plate 6 for discharging. After a period of time, the electric push rod 92 pushes the sliding seat 94, causing the sliding seat 94 to slide on the guide rail 93, and one side of the support plate 2 is pushed up, causing the support plate 2 to deflect and tilt. When the driving motor 102 drives the rotating rod 103 to rotate, the rotating rod 103 drives the filter plate 6 to rotate. There is air blown by a blower inside the square nozzle 12, and the square nozzle 12 faces the filter plate 6. The air blows the material remaining and stuck on the filter plate 6 to clean the filter plate 6.

The key point of each embodiment is to illustrate the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and for the relevant parts, reference can be made to the partial description of the method embodiment.
