A high-efficiency energy-saving environmental protection filter

Abstract

The invention belongs to the technical field of mineral processing, and provides an efficient and energy saving environmentally-friendly filtering machine. The machine comprises a feed hopper and an outlet hopper. Two sides of the feed hopper and the outlet hopper are symmetrically arranged with two groups of vacuum filtering devices. Two sides of the outlet hopper are provided with filter cloth cleaning pools. The vacuum filtering device comprises a filter cloth circulating travelling mechanism, a filtering support plate, and a vacuum negative pressure device. The filter cloth circulating travelling mechanism comprises a filter cloth supporting wheel assembly and a filter cloth. The filter cloth supporting wheel assembly supports the filter cloth and forms a closed circulating path of the filter cloth. The filtering support plate is between the feed hopper and the outlet hopper. The outer side of the filtering support plate is connected with a vacuum housing in a sealed manner. The vacuum housing is externally connected with the vacuum negative pressure device. The filtering support plates on the left side and on the right side are separated by a certain distance and a filtering cavity is formed between the filtering support plates. The cleaning pool is internally provided with cleaning brush. The efficient and energy saving environmentally-friendly filtering machine is simple in structure, clever in design, convenient in use, low in production cost, and high in product qualified rate, and has very high economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to a high-efficiency, energy-saving and environment-friendly filter. Background technique [0002] The following three types of filters are mainly used in the existing mine beneficiation production: [0003] 1. Ceramic filter. Ceramic filter is a new energy-saving product in the mineral processing industry imported from abroad. It has high production efficiency, good dehydration effect of various concentrates, and high product qualification rate. However, it also has some unavoidable problems: (1) The operating cost is far Dozens of times higher than the traditional old-fashioned filter, the cost of the filter itself is high, each in the millions, and the replacement cost of the filter plate is high; (2) The environment is destructive, and highly corrosive nitric acid and sulfuric acid are required in the production process To clean ceramic plates, the industrial water ...
