Device for treating waste filter paper for emulsion in steel rolling

Abstract

The invention provides a device for treating waste filter paper for emulsion in steel rolling. The device comprises a filter paper collecting box body, a first extrusion device, a first blocking device and a pushing device, wherein a containing chamber is formed in the filter paper collecting box body, and a filter paper receiving hopper communicating with the containing chamber is arranged at thetop of the filter paper collecting box body; a plurality of filter liquid holes are formed in the bottom surface of the containing chamber; a filter paper discharge port and a filter paper pushing port are respectively formed in two side walls of one end of the filter paper collection box body in the length direction; the first extrusion device comprises a first extrusion plate arranged in the containing chamber and a first driving element used for driving the first extrusion plate to move horizontally; the first blocking device comprises a first baffle plate arranged on the filter paper discharge port and a second driving element used for driving the first baffle plate to block or open the filter paper discharge port; and the pushing device comprises a pushing plate arranged on the filter paper pushing port and a third driving element used for driving the pushing plate to move towards the filter paper discharge port. The device can realize dry-wet separation of the waste filter paperand carries out reduction treatment, thus reducing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of metallurgical steel rolling, in particular to a device for treating waste filter paper of emulsion in steel rolling. Background technique [0002] At present, a kind of acid rolling mill is often used in the steel rolling production lines of various steel production enterprises. The acid rolling mill is mainly used for tin-plated substrates and ordinary cold-rolled strip products, and emulsifying fluid for lubrication and cooling. Since the maximum speed of the acid rolling mill is 1800mpm, the thinnest rolling specification reaches 0.12mm, the maximum compression ratio reaches more than 91%, and the ratio of T material reaches more than 70%, so the amount of iron powder produced in the emulsion during the rolling process is also much higher. Compared with other acid rolling production lines, the concentration of the emulsion is high. In order to ensure the cleanliness of the emulsion, the emulsion is us...

Problems solved by technology

In the vacuum filter, the filter paper will be continuously consumed during the filtration process, and these discarded filter papers are usually mixed with domestic garbage for disposal. Since there will be waste oil, waste sludge and other liquid residues on the surface of the filter paper, it will affect the ecological environment, soil environment and water quality. serious pollution and damage
