DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4A grinding mill that is easy to replace a filter screen comprises a grinding mill body 1, a discharge port 11 is arranged on one side of the grinding mill body 1, and the discharge port 11 is connected to a filter box 2, a feed port 22 is arranged on one side of the filter box 2, and the feed port 22 is connected to the discharge port 11 of the grinding mill body 1, a fixed shaft 31 is horizontally installed on one side of the filter box 2, a filtering and screening mechanism 3 is rotatably installed in the filter box 2 through the fixed shaft 31, and a collecting box 6 is placed at the bottom of the filter box 2. It is worth noting that the specific structure of the grinding mill body 1 and its working method are both existing technologies currently disclosed on the market, which are common knowledge well known to those skilled in the art, and do not belong to the main technical problems to be solved in the present technical scheme, so they are not elaborated in the present utility model.

[0021] In addition, the filtering and screening mechanism 3 includes a limiting mounting plate 32, a through hole is opened on one side of the limiting mounting plate 32 at the fixed shaft 31, an extension plate 321 is installed in the middle of the other side of the limiting mounting plate 32, and a sliding cavity is opened in the filter box 2 at the extension plate 321.

[0022] At the same time, a limiting groove is opened in the middle of the front end of the limiting mounting plate 32, and a filter screen plate 33 is arranged in the limiting groove. A limiting plate 331 is rotatably installed at an equal distance on the front end of the filter screen plate 33, and a clamping groove is opened in the limiting mounting plate 32 at the limiting plate 331.

[0023] At the same time, a limiting slide groove is opened in the limiting mounting plate 32 on one side of the clamping groove, and through holes are opened at the top and bottom of the limiting mounting plate 32 and in the middle of the filter screen plate 33. It is worth mentioning that the limiting slide groove is located on one side of the clamping groove and away from the side of the electric telescopic rod 7. Through the limiting slide groove, the limiting plate 331 can be easily rotated to be located in the clamping groove.

[0024] Furthermore, a placement cavity is opened below the sliding cavity in the filter box 2, and an electric telescopic rod 7 is placed in the placement cavity. The output end of the electric telescopic rod 7 passes through the placement cavity and is connected to a top extension plate, and a flexible pad is installed on the top of the top extension plate.

[0025] Furthermore, a limiting guide plate 5 is installed above the feed port 22 in the filter box 2, and a guide block 4 is installed between the fixed shaft 31 and the limiting guide plate 5 in the filter box 2, wherein the limiting guide plate 5 is installed at an angle, and the height of the top surface of the limiting guide plate 5 close to the feed port 22 is higher than the height of the top surface away from the feed port 22, and an inclined surface is set on the top surface of the guide block 4 from the side of the feed port 22 toward the side of the filter mesh plate 33.

[0026] A through hole is provided at the front end of the filter box 2 below the guide block 4, and a closing door 21 is installed at the front end of the filter box 2 at the through hole. A visual window is provided in the middle of the front end of the closing door 21, through which the user can observe the real-time status of screening of materials in the filter box 2.

[0027] In this embodiment, the feed port 22 of the filter box 2 is connected to the discharge port 11 of the grinding mill body 1, and then the material entering the filter box 2 is guided downward by the limiting guide plate 5, and the material is further guided by the guide block 4 to ensure that the material falls on the top of the filter screen plate 33.

[0028] The material after being ground by the grinding mill body 1 is screened and filtered through the filter screen plate 33 to remove impurities or larger particles in the material and ensure the quality and purity of the material. When the filter screen plate 33 filters and screens the material, the output end of the electric telescopic rod 7 indirectly rises or moves down, so that the limit mounting plate 32 rotates around the fixed axis 31 within a certain range to avoid accumulation of the material on the top of the filter screen plate 33, thereby improving the filtering efficiency of the filter screen plate 33. In addition, since the output end of the electric telescopic rod 7 passes through the placement cavity and is connected to a top extension plate, a flexible pad is installed on the top of the top extension plate, so that one end of the limit mounting plate 32 is flexibly pressed by the flexible pad.

[0029] Furthermore, the filter screen plate 33 is detachable and can be disassembled and cleaned after being used for a period of time to remove accumulated impurities and larger particles, thereby maintaining the cleanliness and filtering efficiency of the filter screen plate 33.

[0030] In the utility model, the material after being ground by the grinding mill body 1 is screened and filtered through the filter screen plate 33 to remove impurities or larger particles in the material, thereby ensuring the quality and purity of the material. The filter screen plate 33 is detachable and can be disassembled and cleaned after being used for a period of time to remove the accumulated impurities and larger particles, thereby maintaining the cleanliness and filtering efficiency of the filter screen plate 33.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
