Zinc and nickel impregnation agent pulp washing filtered water recycling device

Abstract

The invention discloses a zinc and nickel impregnation agent pulp washing filtered water recycling device. The zinc and nickel impregnation agent pulp washing filtered water recycling device is characterized in that a framework is arranged in a clear water basin and comprises an upper framework seat, a lower framework seat and a plurality of guiding upright columns, and an upper sliding plate and a lower sliding plate are disposed between the upper framework seat and the lower framework seat, are sleeved on the guiding upright columns and can slide up and down; through holes are arranged on the upper sliding plate and the lower sliding plate and are in one-to-one correspondence with one another, a filter bag is arranged in each through hole of the upper sliding plate, and frames are arranged in the filter bags; each frame comprises an upper flange at the upper end of the frame, a frame seat at the lower end of the frame and a plurality of filter bag support rods arranged between the upper flange and the frame seat; a slurry tank is arranged on the upper sliding plate, an output shaft of an electric elevator is connected with the bottom of the slurry tank; sliding dry columns are disposed on the lower framework seat, and upper ends of the sliding dry columns extend into the filter bags and are connected with mud core supporting plates. A filtering method is adopted for impregnation agent pulp washing dewatering, and is free of energy consumption. Besides, the filtering area is greatly increased owing to the multiple filter bags, and water filtration efficiency is improved. In addition, impregnation agent mud cores can be separated from the filter bags easily, recycling is facilitated, the filter bags can be cleaned automatically, and a good water filtration function is kept.

Description

technical field [0001] The invention relates to the follow-up technical improvement of zinc-nickel permeation layer treatment products, and specifically refers to a device for filtering the pulp of the zinc-nickel permeation agent to recover the permeation agent. Background technique [0002] Zinc-nickel coating technology is a metal anti-corrosion technology developed by the National Innovation Fund for Small and Medium-sized Enterprises. It forms a zinc-nickel coating anti-corrosion layer on the surface of metal workpieces. In mass production, the usual zinc-nickel coating treatment process is: alkali washing degreasing - shot blasting derusting - heating coating - rolling deliming - shot blasting deashing - water washing deashing. [0003] After rolling deashing and shot blasting, a small amount of penetrating agent dust remains on the surface of the workpiece, which needs to be poured into the ash washing tank to wash off the residual ash of penetrating agent attached to...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that existing metal workpieces are difficult to wash and remove water after anti-corrosion treatment of the zinc-nickel coating, the purpose of the present invention is to provide a kind of equipment that can efficiently filter out the water in the washing pulp to achieve the purpose of recovering the zinc-nickel coating. device
