In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0020] like Figure 1-4 As shown, a filtering device for anchoring agent production includes an operating table 1, and also includes an upper filter assembly 2, a middle filter assembly 3, and a lower filter assembly 4 arranged in sequence in a vertical direction. The operating table is installed with a lifting structure for driving the upper filter assembly to rise and fall in the vertical direction. The upper filter assembly and the middle filter assembly are connected by a joint lifting structure 5. The lower filter assembly is fixedly mounted on the operating table. The upper filter assembly, the middle filter assembly, and the lower filter assembly have the same structure. The upper filter assembly, the middle filter assembly, and the lower filter assembly all include filter screens, and the mesh size of the filter screens decreases in sequence.

[0021] The operating table is provided with a drop hole facing the lower filter assembly, and a drop hopper is fixedly installed in the operating table facing the drop hole. The drop hopper is fixedly connected outwardly with a discharge pipe 6 arranged to be tilted downward.

[0022] In this way, an upper filter assembly, a middle filter assembly, and a lower filter assembly are provided, achieving three-stage filtration. As the upper filter assembly is raised by the lifting structure, the middle filter assembly is also raised by the lifting assembly, separating the upper, middle, and lower filter assemblies for easier cleaning. The upper, middle, and lower filter assemblies all include filter screens with successively smaller mesh sizes, which improves filtration accuracy. After filtering, the raw material falls through the drop hole, is collected by the drop hopper, and then discharged from the discharge pipe.

[0023] During implementation, the upper filter assembly, the middle filter assembly and the lower filter assembly all include an outer frame 7, a collecting hopper 8 and a mesh cylinder 9; the outer frame is cylindrical, and the upper and lower ends of the outer frame are both protruding outward with a convex edge 10, and a sinking platform 11 is provided on the outer frame, the upper end of the collecting hopper is protruding outward with a folding edge 12, and the folding edge is overlapped on the sinking platform, and the collecting hopper is trumpet-shaped, and the upper end of the mesh cylinder is fixed with a lap edge 13, and the lap edge is overlapped on the folding edge, and the upper surface of the lap edge is flush with the upper surface of the convex edge at the upper end of the mesh cylinder, and a DC vibration motor 14 is fixed on the outside of the mesh cylinder, and the side walls of the mesh cylinder 9 and the side walls of the collecting hopper 8 are spaced apart so that a space for accommodating the DC vibration motor 14 is formed between the side walls of the mesh cylinder 9 and the side walls of the collecting hopper 8, and the DC vibration motor 14 is spaced apart from the collecting hopper 8; the filter is fixedly mounted on the lower end 15 of the mesh cylinder, and the outer frame of the lower filter assembly is fixedly connected to the operating table. In this way, the outer frame, collection hopper, and mesh cylinder are stacked in sequence, facilitating quick connection and disassembly. The raw material reaches the mesh cylinder and is filtered through the filter at its lower end. The connection is achieved through the folded and overlapped edges, with the upper surface of the overlapped edge flush with the upper surface of the raised edge at the mesh cylinder's upper end, ensuring that the upper, middle, and lower filter assemblies fit together during use. A DC vibration motor provides vibration to improve filtration efficiency, and the system is powered by a lithium battery for ease of use.

[0024] During implementation, the sinking platform is fixed with spaced apart limiting blocks 16, the folding edge is provided with limiting openings 17 for engaging with the limiting blocks, and the thickness of the limiting blocks is the same as that of the folding edge, thereby improving stability.

[0025] During implementation, an anti-rotation block 18 is protruding from the folded edge, and an anti-rotation opening 19 is provided on the overlapped edge to engage with the anti-rotation block. The thickness of the anti-rotation block is the same as that of the overlapped edge, thereby improving stability and preventing rotation.

[0026] During implementation, guide rods 20 are fixed on both sides of the operating table, and guide blocks 21 that slide with the guide rods are fixed on both sides of the outer frame, so as to guide the movement of the upper filter assembly and the middle filter assembly.

[0027] During implementation, the lifting structure comprises two symmetrically arranged lifting assemblies, each of which includes a column 22 fixedly mounted on the operating table. A mounting slot is defined on the side of the column facing the guide rod, within which a screw is mounted via a bearing. A servo motor 23 is fixedly mounted at the upper end of the column. The servo motor's output shaft passes through the column and is fixedly connected to the upper end of the screw. Nut blocks are threadedly connected to the screw, and guide blocks on either side of the outer frame of the upper filter assembly are fixedly connected to the nut blocks. The servo motor drives the screw to rotate, which, through the nut blocks and guide blocks, drives the upper filter assembly up and down.

[0028] During implementation, the joint lifting structure includes two lifting arms 24, each of which is provided with a lifting groove 25. The lower end of the lifting arm is fixedly connected to the guide block on the outer side of the outer frame of the middle filter assembly through a connecting rod. The guide block on the outer side of the outer frame of the upper filter assembly is fixed with a pin 26, and the pin is slidably matched with the lifting groove. During the rising process of the upper filter assembly, the pin drives the lifting arm to move, thereby driving the middle filter assembly to rise, and the middle filter assembly is spaced apart from the upper filter assembly to facilitate cleaning of the upper filter assembly, the middle filter assembly and the lower filter assembly. When it is needed, the lifting structure drives the upper filter assembly to descend, and under the action of gravity, the middle filter assembly descends, finally achieving the fitting of the upper filter assembly, the middle filter assembly and the lower filter assembly.

[0029] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
