Detailed Embodiment

[0023] The present utility model will be further described below in conjunction with the drawings and the detailed embodiment:

[0024] As Figures 1 to 5 shown, this embodiment provides a solid-liquid separation device for diamond micropowder, including a cylinder body 1. Upper and lower covers 2 and 3 are detachably arranged at both ends of the cylinder body 1 respectively. Both the upper cover 2 and the lower cover 3 are hollow hemispherical covers. Anticorrosion layers are provided on the inner walls of the cylinder body 1, the upper cover 2 and the lower cover 3 to prevent corrosion by acidic liquids. For some diamond micropowders after pickling containing acidic liquids, which are likely to cause corrosion damage to the inner walls of the equipment. Therefore, an anticorrosion layer made of polytetrafluoroethylene material is adopted to avoid corrosion damage when the interiors of the cylinder body 1, the upper cover 2 and the lower cover 3 come into contact with acidic liquids. A filter screen plate 4 is arranged between the cylinder body 1 and the lower cover 3. During use, a layer of filter paper is laid above the filter screen plate 4, and then pressure is applied to the cylinder body 1 to achieve solid-liquid separation. The diamond micropowder is left above the filter screen plate 4, and the liquid enters the lower cover 3 through the mesh holes on the filter screen plate 4.

[0025] A driving device 5 is fixedly arranged at the top of the upper cover 2. The driving device 5 is a motor. The output end of the driving device 5 penetrates the upper cover 2 and extends into the cylinder body 1 and is fixedly connected to a rotating rod 11. As Figure 4 shown, a plurality of stirring rods 12 are fixedly connected to the rotating rod 11. By driving the rotating rod 11 to rotate through the driving device 5, the plurality of stirring rods 12 are driven to rotate around the rotating rod 11, realizing the stirring of the materials in the cylinder body 1, further ensuring the water washing or pickling effect of the diamond micropowder, and improving the filtration efficiency. A guide plate 13 is fixedly arranged at the end of the stirring rod 12. The outer side of the guide plate 13 contacts the inner wall of the cylinder body 1. Each guide plate 13 is inclined downward along the inner wall of the cylinder body 1 from top to bottom. The rotating rod 11 and the plurality of guide plates 13 are both located above the filter screen plate 4. When the stirring rod 12 rotates, it drives the guide plate 13 to rotate circumferentially along the inner wall of the cylinder body 1, thereby preventing the materials from adhering to the inner wall of the cylinder body 1. And because the guide plate 13 is integrally arranged in an arc shape and inclined, during the rotation process, it drives the diamond micropowder materials to be conveyed downward, ensuring the filtration and separation effect. In addition, among the upper and lower corresponding plurality of guide plates 13, the lower end of the guide plate 3 located above is lower than the upper end of the adjacent guide plate 13 located below, ensuring the scraping effect on the inner wall of the cylinder body 1, and the arrangement of the guide plate 13 further improves the stirring effect of the materials in the cylinder body 1.

[0026] The upper cover 2 is also provided with a feeding port 6 and a main pipe 7. A pressure gauge 8 is arranged on the main pipe 7, and an air inlet pipe 9 and an exhaust pipe 10 are respectively and communicatively arranged. Valves are arranged on both the air inlet pipe 9 and the exhaust pipe 10. The diamond micropowder material mixed with liquid is added into the equipment (here, the equipment refers to the whole solid-liquid separation equipment composed of the cylinder body 1, the upper cover 2, the lower cover 3, etc.) through the feeding port 6. Subsequently, ensure the equipment is sealed, and gas is introduced into the equipment through the air inlet pipe 9 via the main pipe 7 to achieve positive pressure filtration, that is, solid-liquid separation. The pressure inside the equipment is observed through the pressure gauge 8. After the solid-liquid separation is completed, the high-pressure gas is discharged through the exhaust pipe 10.

[0027] It should be noted that the air inlet pipe 9 can be connected to an air compressor to provide gas for the equipment.

[0028] The upper cover 2 is also fixedly provided with a handle 15, which is convenient for holding when moving the upper cover 2 or performing other operations.

[0029] The lower end of the lower cover 3 is communicatively provided with a discharge pipe 14. The discharge pipe 14 is connected with a discharge pipe 16. A liquid discharge valve 17 is arranged on the discharge pipe 16. During the positive pressure separation process, the liquid in the material in the cylinder body 1 is separated from the diamond micropowder under its own gravity and positive pressure, and after passing through the filter mesh plate 4, it falls into the lower cover 3. At the same time, under the positive pressure, it is discharged and collected through the discharge pipe 14 and then through the discharge pipe 16. The opening and closing of the discharge pipe 16 are adjusted through the liquid discharge valve 17.

[0030] A plurality of legs 18 are fixedly arranged on the outer circumference of the lower cover 3 for supporting the whole solid-liquid separation device.

[0031] First flange plates 19 are fixedly arranged at both ends of the cylinder body 1. Second flange plates 20 and third flange plates 21 are respectively fixedly arranged on the end faces of the upper cover 2 and the lower cover 3. The first flange plate 19 and the second flange plate 20, and the first flange plate 19 and the third flange plate 21 are fixedly connected through a locking mechanism. At the same time, the sealing connection between the cylinder body 1 and the upper cover 2, and the cylinder body 1 and the lower cover 3 is realized through the cooperation of the locking mechanism and a plurality of flange plates.

[0032] Such as Figure 5As shown, the locking mechanism includes a screw rod 22, a nut 23, a handle ring 24, a hinged rod 25 and a limiting member. A plurality of limiting members are fixedly arranged circumferentially on the arc-shaped sides of the first flange plate 19, the second flange plate 20 and the third flange plate 21. The limiting members on the adjacent and corresponding first flange plate 19 and second flange plate 20 are vertically corresponding, and the limiting members on the adjacent and corresponding first flange plate 19 and third flange plate 21 are vertically corresponding. The limiting member includes two oppositely arranged limiting plates 26. A hinged rod 25 is rotatably arranged on the limiting member corresponding to the first flange plate 19. The hinged rod 25 is rotatably arranged between the corresponding two limiting plates 26. A screw rod 22 is fixedly connected to the arc-shaped side of the hinged rod 25. The diameter of the screw rod 22 is smaller than the distance between the adjacent two limiting plates 26. After the free end of the screw rod 22 passes through the corresponding two limiting plates 26 on the second flange plate 20 or the third flange plate 21, a nut 23 is sleeved on the screw thread. By rotating the nut 23 to make it press against the corresponding limiting member, the adjacent two flange plates are locked. The nut 23 is fixedly connected with a handle ring 24. The handle ring 24 is an annular rod, and the free ends of the screw rod 22 extend into the inner side of the corresponding handle ring 24. The outer diameter of the nut is larger than the distance between the two limiting plates 26 of the corresponding limiting member. The nut 23 can be conveniently rotated through the handle ring 24. At the same time, when the solid-liquid separation device needs to be disassembled, the handle ring 24 is rotated in the reverse direction to loosen the locking of the nut 23. Subsequently, the screw rod rotates around the corresponding hinged rod 25, so that the free end of the screw rod 22 moves away from the upper limiting member above it, and the locking of the two flange plates is immediately cancelled.

[0033] During use, first, the locking mechanism is used to ensure the sealed and fixed connection between the cylinder body 1 and the upper sealing plate 2 and the lower sealing plate 3. Subsequently, the feeding port 6 is opened, and the diamond micropowder material mixed with liquid is added into it. Then the feeding port 6 is closed, the valves on the liquid outlet valve 17 and the air inlet pipe 9 are opened, and gas is conveyed to the air inlet pipe 9 through equipment such as an air compressor, so that a positive pressure is formed inside the solid-liquid separation device. Under the action of the positive pressure and the self-gravity of the liquid, the liquid falls through the mesh holes of the filter screen plate 4 into the lower sealing plate 3 and is discharged and collected through the discharge pipe 14 and the discharge pipe 16. During this process, the pressure inside the device can be observed through the pressure gauge 8 subsequently to ensure the pressure filtration effect. During the pressure process, by starting the motor, the stirring rod 12 and the guide plate 13 are driven to rotate, and the material is stirred to flow, further strengthening the pressure filtration effect and reducing or even avoiding the adhesion of the diamond micropowder material on the inner wall of the cylinder body 1.

[0034] After the solid-liquid separation is completed, by loosening the locking mechanism, the first flange plate 19 is separated from the third flange plate 21, and then the cylinder body 1 and the upper cover 2 are removed. The diamond micropowder after the solid-liquid separation is located above the filter mesh plate 4. At the same time, there is a filter paper between the filter mesh plate 4 and the diamond micropowder. On the one hand, it avoids the diamond micropowder being discharged together with the separated liquid due to the too large mesh holes of the filter mesh plate 4, and avoids the contact between the diamond micropowder and the filter mesh plate 4, which is convenient for cleaning the filter mesh plate 4.

[0035] If it is necessary to clean the cylinder body 1, the upper sealing plate 2 and the lower sealing plate 3, the locking mechanisms of the first flange plate 19 and the second flange plate 20 are loosened simultaneously, and then the corresponding devices can be cleaned separately, which is convenient and simple.

[0036] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent shall be included in the scope of the present invention's patent application.
