[0002] The grinding and polishing agent, that is, the grinding fluid, is composed of aviation gasoline, kerosene, transformer oil, various vegetable oils, animal oils and hydrocarbons, and is equipped with several additives. It is widely applicable to the grinding and polishing of hard materials such as superhard materials and cemented carbides for electronic products. It can not only improve the grinding rate, but also quickly discharge a large amount of heat generated during the grinding process, thus avoiding the workpiece surface from being burned. After the grinding fluid is used, the iron filings and residues in it need to be filtered out, so a filtering device is required.

[0003] For example, in the utility model patent with the publication number of CN216457192U, a filtering device for grinding fluid production is disclosed. By feeding the grinding fluid into the filtering tank body, after the grinding fluid is filtered through the first filtering layer and the second filtering layer, it is then discharged through the discharge port.

[0004] However, after the utility model is used for a period of time, when the first filtering layer and the second filtering layer need to be cleaned, it is necessary to remove the round cover plate from the filtering tank body, which is relatively laborious for personnel to operate. In addition, filtering cannot be carried out simultaneously during cleaning, which will affect the filtering efficiency. Content of the Utility Model

A pair of partition boards 4 are oppositely provided on the rotating shaft 3. Two pairs of support grooves 5 are provided on both sides of each partition board 4 at different vertical heights. Two pairs of support rods 6 with the same height as the support grooves 5 are provided on the rotating shaft 3. Each pair of support rods 6 and two pairs of support grooves 5 at the same height are arranged in a cross shape. A semi-circular filter plate 7 is inserted on each pair of support grooves 5 and support rods 6 on the same side of a pair of partition boards 4; A pair of limit strips 7-1 are provided at the bottom of each semi-circular filter plate 7, each limit strip 7-1 is inserted into the support groove 5, a pair of insert blocks 7-2 are provided at the bottom of each semi-circular filter plate 7, a pair of insertion holes 6-1 are provided on each support rod 6, and a pair of insert blocks 7-2 are inserted into a pair of insertion holes 6-1; The pore diameters of the filter holes on the upper pair of semi-circular filter plates 7 are larger than those of the lower pair of semi-circular filter plates 7; An inclined plate 10 is provided at the bottom of the inner cavity of the box body 1, the liquid outlet pipe 12 is communicatively provided at the bottom of the box body 1 and is located at the low-end side of the inclined plate 10, a groove is provided on the inclined plate 10, and a bearing 11 is provided in the groove. The inner ring of the bearing 11 is connected to the bottom of the rotating shaft 3; A reinforcing rod 8 is provided between each support rod 6 and the rotating shaft 3.

[0021] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] In the present invention, the motor 2 is connected to an external electric control system through a wire. The above equipment and connection methods are existing technologies and will not be elaborated here.

[0023] According to the attached instructions Figures 1-4 It can be seen that when the utility model is in use, the grinding fluid to be filtered is injected into the box body 1 through the liquid inlet pipe 13 at the top of the box body 1. After the grinding fluid is filtered by a pair of semi-circular filter plates 7 at different vertical heights on the same side of a pair of partition plates 4, it flows out from the liquid outlet pipe 12 at the bottom of the box body 1. When it is necessary to clean the semi-circular filter plates 7 after using for a period of time, the motor 2 arranged at the top of the box body 1 is started. The motor 2 is preferably a servo motor, so that the motor 2 drives the connected rotating shaft 3 to rotate 180 degrees. The rotating shaft 3 drives a pair of semi-circular filter plates 7 to be cleaned to rotate to the position of the box door 9. At the same time, a pair of semi-circular filter plates 7 that were originally at the box door 9 and have not filtered the grinding fluid are rotated below the liquid outlet pipe 12 to filter the grinding fluid. The operator opens the box door 9, lifts each semi-circular filter plate 7 by a certain height from a pair of support grooves 5 and support rods 6 respectively, and then takes out the partition plate 4 from the box body 1 for cleaning. After cleaning, the semi-circular filter plate 7 is moved into the box body 1, and the semi-circular filter plate 7 is inserted into a pair of support grooves 5 and support rods 6 again. A pair of support grooves 5 and support rods 6 can support and limit the semi-circular filter plate 7. The utility model drives the rotating shaft 3 to rotate 180 degrees through the motor 2, so that the semi-circular filter plates 7 that have filtered the grinding fluid and those that have not been used are exchanged in position, and then the semi-circular filter plate 7 with metal debris on it is taken out of the box body 1 for cleaning. The process of taking out the semi-circular filter plate 7 is simple, and the grinding fluid can be filtered during the cleaning process without affecting the filtration progress, thereby improving the filtration efficiency.

[0024] There is a possible implementation. A pair of limit strips 7-1 at the bottom of each semi-circular filter plate 7 are inserted into the corresponding pair of support grooves 5, and a pair of insertion blocks 7-2 at the bottom of the semi-circular filter plate 7 are inserted into a pair of insertion holes 6-1 on the lower support rod 6. A pair of support grooves 5 and support rods 6 support the semi-circular filter plate 7, and the insertion of a pair of insertion blocks 7-2 into a pair of insertion holes 6-1 can limit the semi-circular filter plate 7 to prevent the semi-circular filter plate 7 from undergoing horizontal displacement on the support grooves 5 and support rods 6.

[0025] There is a possible implementation. The pore diameter of the filter holes on the upper pair of semi-circular filter plates 7 is larger than that of the lower pair of semi-circular filter plates 7. The upper semi-circular filter plates 7 conduct preliminary filtration on the grinding fluid, thereby filtering out metal debris with larger particle sizes. The lower semi-circular filter plates 7 filter the grinding fluid again to filter out metal debris with smaller particle sizes, thereby improving the filtration effect.

[0026] There is a possible implementation. The inclined plate arranged at the bottom of the inner cavity of the box body 1 can enable the grinding fluid to flow out from the liquid outlet pipe 12. The bottom of the rotating shaft 3 is connected to the inner ring of the bearing 11, and the outer ring of the bearing 11 is connected to the groove wall of the inclined plate, thereby preventing the rotating shaft 3 from shaking when rotating.

[0027] There is a possible implementation. A reinforcing rod 8 is provided between each support rod 6 and the rotating shaft 3, and the reinforcing rod 8 supports and fixes the support rod 6.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
