By adding an appropriate amount of grinding aid to the mill, the grinding process can be significantly improved, production efficiency increased, and energy consumption reduced.

[0003] Before using raw material grinding aids, in order to remove impurities and precipitates and ensure product quality and stability, the raw material grinding aids are usually filtered. Solid particles, precipitates or other unwanted components in the grinding aids are separated by physical or chemical methods.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The present invention provides a technical solution: a raw material grinding aid filtration device, including a barrel 1, a servo electric cylinder 2 installed on the outside of the barrel 1, a piston rod 4 fixed to the upper end of the servo electric cylinder 2 through a connecting rod 3, a piston 16 installed at the lower end of the piston rod 4, the piston 16 and the piston rod 4 are both located inside the barrel 1, and the piston 16 is sealed to the inner wall of the barrel 1.

[0024] A backflow preventer 5 is installed at the liquid inlet on the tank body 1, which can prevent the raw material grinding aid in the tank body 1 from flowing back during liquid discharge, thus ensuring the normal conveying of the raw material grinding aid.

[0025] Furthermore, the backstop assembly 5 includes a main body 501, a lower cover 502, an upper cover 503, a spring 504, a sealing block 505, and a protrusion 506. The upper cover 503 and the lower cover 502 are respectively installed on the upper and lower sides of the main body 501. The upper cover 503 and the lower cover 502 facilitate the maintenance of the backstop assembly 5. The spring 504 is connected to the inner side of the upper cover 503. The sealing block 505 is connected to the lower end of the spring 504. The sealing block 505 and the spring 504 are both located inside the main body 501. The protrusion 506 is also provided inside the main body 501. The protrusion 506 and the sealing block 505 are in close contact due to the compression of the spring 504, ensuring stable contact between the sealing block 505 and the protrusion 506.

[0026] Furthermore, the main body 501 is provided with an inlet and an outlet. The outlet on the main body 501 is connected to the inlet flange on the barrel 1, which facilitates the disassembly and assembly of the main body 501. The protrusion 506 and the sealing block 505 are located between the inlet and outlet on the main body 501 to ensure the normal backflow prevention effect of the main body 501 and prevent the raw material grinding aid from flowing back.

[0027] Furthermore, the lowest position of the piston 16 when moving up and down inside the barrel 1 is above the liquid inlet on the barrel 1, so the movement of the piston 16 does not affect the liquid inlet operation.

[0028] A discharge hopper 8 is installed on the lower side of the barrel body 1. A disassembly assembly for opening the discharge hopper 8 is provided between the discharge hopper 8 and the barrel body 1. A liquid outlet 9 is provided on the lower side of the discharge hopper 8, and a backflow prevention assembly 5 is also installed on the liquid outlet 9 to ensure that the discharged raw material grinding aid does not flow back when it is being extracted.

[0029] Furthermore, the disassembly assembly includes an upper connecting edge 6, a lower connecting edge 7, a rotating shaft 10, a screw 11, a nut 12, and a hinge 13. The upper connecting edge 6 is located at the lower edge of the barrel body 1, and the lower connecting edge 7 is located at the upper edge of the discharge hopper 8. The screw 11 is movably mounted on the lower connecting edge 7 via the rotating shaft 10, and the nut 12 is mounted on the screw 11. The screw 11 rotates via the rotating shaft 10, which facilitates the compression and limiting fixation of the upper connecting edge 6 and the lower connecting edge 7. The upper connecting edge 6 and the lower connecting edge 7 form a flipping structure through the hinge 13, which facilitates the opening of the discharge hopper 8, thereby facilitating the disassembly and replacement of the filter assembly and ensuring the continuous and normal operation of the filter.

[0030] Furthermore, the upper connecting edge 6 and the lower connecting edge 7 are fixed together by a rotating shaft 10, a screw 11 and a nut 12, ensuring a stable connection between the upper connecting edge 6 and the lower connecting edge 7, thereby ensuring that the filtration operation is normal.

[0031] A filter assembly is installed between the barrel 1 and the discharge hopper 8, and the filter assembly and the barrel 1 and the discharge hopper 8 are sealed together.

[0032] Furthermore, the filter assembly includes a sealing edge 14 and a filter screen 15. The filter screen 15 is fixed inside the sealing edge 14 and has a concave structure to facilitate the filtration of raw material grinding aids. The sealing edge 14 is located between the upper connecting edge 6 and the lower connecting edge 7, and a rubber pad is provided on the outside of the sealing edge 14. The fixed connection between the upper connecting edge 6 and the lower connecting edge 7 and the sealing edge 14 form a compression sealing structure, which not only ensures the stable working state of the sealing edge 14 and the filter screen 15, but also effectively avoids leakage and allows the filtration work to proceed normally.

[0033] Working principle: When using this raw material grinding aid filter device, firstly, the liquid inlet on the non-return component 5 needs to be connected to the material tank storing the raw material grinding aid. Then, the servo electric cylinder 2 is started, and the piston rod 4 is moved up and down through the connecting rod 3, thereby causing the piston 16 to move up and down inside the tank 1.

[0034] Since both the inlet on the barrel 1 and the outlet 9 on the hopper 8 are equipped with check valve components 5, when the piston 16 moves upward inside the barrel 1, the barrel 1 is under negative pressure. The check valve component 5 connected to the barrel 1 is opened by pressure, while the check valve component 5 on the hopper 8 is closed by pressure. The raw material grinding aid in the barrel enters the barrel 1 through the check valve component 5 connected to the barrel 1.

[0035] Afterwards, the raw material grinding aid will fall into the filter screen 15 for filtration. At the same time, the servo electric cylinder 2 drives the piston 16 to press down, so that the raw material grinding aid that has entered the barrel 1 is discharged from the backstop component 5 on the liquid outlet 9. The pressing down of the piston 16 can also make the raw material grinding aid pass through the filter screen 15 quickly, thereby quickly completing the filtration work.

[0036] When the filter screen 15 needs to be replaced, the nut 12 can be loosened to separate the screw 11 from the upper connecting edge 6, and the fixed connection between the upper connecting edge 6 and the lower connecting edge 7 can be released. Then the discharge hopper 8 can be opened directly downwards to take out the filter screen 15 for replacement. Finally, the upper connecting edge 6 and the lower connecting edge 7 can be fixed by the screw 11 and the nut 12 to ensure the stable and normal filtering process of the filter screen 15.

[0037] The above describes the working process of the device, and all content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
