Description

Technical Field

[0001] The utility model relates to the technical field of zinc-aluminum coating liquid preparation, and specifically, to a filtering device for zinc-aluminum coating liquid preparation with a filter element that is convenient to disassemble and assemble. Background Art

[0002] During the preparation and processing of zinc-aluminum coating liquid, there will be a lot of impurities in the liquid. If these impurities are not filtered, the quality of the finished zinc-aluminum coating liquid will be affected. Therefore, a filtering device is needed.

[0003] The following problems exist in the prior art:

[0004] In the prior art, for the filter element of the filtering device, that is, the filter plate, after being used for a period of time, people need to open the cover plate of the filter box to take it out from the inside, clean it, and then install it back into the filter box in the same way. The whole process is rather cumbersome, and people need to keep bending down and stretching their hands into the inside of the filter box, which is quite labor-consuming. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model provides a filtering device for zinc-aluminum coating liquid preparation with a filter element that is convenient to disassemble and assemble, so as to overcome the above technical problems existing in the prior related art.

[0006] Therefore, the specific technical solution adopted by the utility model is as follows:

[0007] A filtering device for zinc-aluminum coating liquid preparation with a filter element that is convenient to disassemble and assemble includes a filter box. The top of the filter box is hinged with a cover plate through a hinge. The surface of the cover plate is provided with a feed port. The bottom of the filter box is provided with a discharge port. The inner side wall of the filter box is provided with a limit groove. A sliding rod is arranged on the inner wall of the limit groove. A sliding block is sleeved outside the sliding rod. A docking block is fixedly connected to the surface of the sliding block. A socket is opened at the top of the docking block. An insertion plate is inserted into the socket. A filter mesh plate is fixedly connected to the top of the insertion plate. An inlet and outlet is opened at the middle of the front of the filter box.

[0008] Preferably, a return spring is fixedly connected to the inner side wall of the limit groove. The end of the return spring is fixedly connected with a clamping plate. By providing the clamping plate, after the contraction and deformation of the return spring, the insertion plate at the bottom of the filter mesh plate can be fixed, avoiding the filter mesh plate being ejected due to the too large impact force of the falling zinc liquid or aluminum liquid above.

[0009] Preferably, an anti-slip pad is bonded to the surface of the clamping plate. Multiple groups of anti-slip convex points are arranged on the surface of the insertion plate. By providing the anti-slip pad and the anti-slip convex points, the docking stability between the filter mesh plate and the docking block can be further increased.

By arranging the pulling handle, it is convenient for people to draw the filter mesh plate to the outside of the filter box, and then the filter mesh plate can be drawn out from the limiting groove on the docking block through the lifting handle to complete quick disassembly.

[0011] Preferably, a connecting plate is fixedly connected to the front of the filter box near the top. A motor is fixedly installed on the outside of the connecting plate. A lead screw is arranged on the inner side wall of the connecting plate. A connecting block is sleeved on the outside of the lead screw. A connecting rod is threadedly connected to the side surface of the connecting block. A cleaning blade is fixedly connected to the end of the connecting rod. By arranging the cleaning blade, when the motor drives the lead screw to drive the connecting block to move, the impurities falling on the surface of the filter mesh plate drawn to the outside can be cleaned, and the metal residues and impurities are pushed off from the mesh holes on the surface of the filter mesh plate.

[0012] Preferably, an observation port is opened at the upper part of the side surface of the filter box, and a heat-insulating transparent glass is fixedly installed on the inner wall of the observation port. By arranging the observation port, it is convenient for people to see whether there is impurity accumulation on the filter mesh plate inside the filter box.

[0013] Preferably, movable wheels are arranged at the four corners of the bottom of the filter box, and a push-pull handrail is arranged at the upper part of the left side of the filter box. By arranging the movable wheels, the equipment can move flexibly and is convenient to use in multiple preparation workshops.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the filter device for preparing zinc-aluminum coating solution with a filter element that is convenient for disassembly and assembly, by arranging the sliding block, which moves horizontally on the sliding rod, the docking block can enter and exit from the inlet and outlet, so that the filter mesh plate installed on the docking block can be drawn out of the filter box, and then the filter mesh plate can be taken out from the limiting groove on the docking block to complete disassembly. When installing, just operate in the reverse way. After the clamping plate contracts and deforms under the action of the reset spring, it can fix the plug plate at the bottom of the filter mesh plate to prevent the filter mesh plate from popping out due to the too large impact force of the zinc liquid or aluminum liquid falling from above.

[0016] 2. For the filter device for preparing zinc-aluminum coating solution with a filter element that is convenient for disassembly and assembly, by arranging the cleaning blade, when the motor drives the lead screw to drive the connecting block to move, the impurities falling on the surface of the filter mesh plate drawn to the outside can be cleaned, and the metal residues and impurities are pushed off from the filter mesh plate to keep the filter mesh plate clean.
