Description

Mining cylinder filter

Technical Field

The utility model relates to a mineral production technical field, concretely relates to mining drum filter.

Background

In the process of mineral extraction, a filter is required for removing water in ore pulp, the current mining filter is mainly divided into three types, namely a cylindrical filter, a disc filter and a turnover filter, and compared with other two types of filters, the cylindrical filter is relatively simple in structure and low in failure rate.

As shown in FIG. 3, the principle of the cylindrical filter is that the inside of the cylindrical filter is a hollow large cylinder made of iron or wood, a plurality of small ditches are arranged on the surface of the cylinder, and the surface of the cylinder is covered with filter cloth. The whole cylinder can be roughly divided into three sections, wherein the small ditch between 1 and 3 sections is connected with an air extractor (namely a vacuum pump) through a pipeline, and the small ditch between 2 sections is connected with a blower (namely an air compressor) through a pipeline. When the cylinder is in the 3 rd interval, the ore particles in the pulp tank are sucked to the filter cloth of the cylinder to form a primary filter cake, namely a filtering area, due to the air exhaust of the air exhauster (namely, a vacuum pump). When the cylinder continues to run to the 1 st zone, the water content of the filter cake is further sucked dry due to the continuous pumping of the vacuum pump, and the zone is called a suction dry zone. When the cylinder rotates to the 2 nd area, the filter cake adhered on the filter cloth of the cylinder is blown off by the pipeline connected with the pressure fan and is scraped off from the filter cloth by the scraper. This completes a filtration cycle.

The existing cylinder filter can maintain normal working efficiency only by keeping higher pulp concentration in the production process, but even the existing cylinder filter still needs to capture mineral fine powder floating randomly in a pulp pool, and the working efficiency is still insufficient.
