A high pressure filter press

Abstract

The invention relates to the field of filter press technology, in particular to a high-pressure filter press. The upper beam and the lower beam are fixedly connected by a plurality of vertical columns; the movable beam and the middle mold can move up and down along the column, and the movable beam is placed in the middle. above the mold; the upper cylinder is fixed on the upper beam to drive the movable beam to move up and down; the lower cylinder is fixed to the lower beam to drive the middle mold to move up and down; the middle mold has a cavity connecting the upper and lower ends, and the upper mold is fixed to the lower end of the movable beam. The lower mold is fixed on the upper end of the lower beam, and the upper mold and the lower mold can make the mold cavity form a sealed cavity; the lower end of the upper mold and / or the upper end of the lower mold are respectively fixed with a filter cloth; the lower end of the upper mold and / or the lower mold The upper end of the mold is provided with a through hole for filtering water. Through the above structure, the present invention can move the movable upper mold and the middle mold up and down, and the process of loading, pressing and unloading materials is simple and convenient. pressure, saving energy consumption by 30%‑50%.

Description

technical field [0001] The invention relates to the technical field of filter press, in particular to a high-pressure filter press. Background technique [0002] After the raw ore enters the concentrator and undergoes crushing, grinding and sorting operations, the useful minerals in the ore are sorted into one or more concentrate products. The tailings are discharged in the state of slurry. The concentrate yield is small, and the concentrate yield of non-ferrous metal concentrators is generally only 10% to 20%; the tailings are large, and the yield is generally 80% to 90%; even larger. If a small concentrator with a daily processing capacity of 100 tons can discharge more than 80-90 tons of tailings per day; if the grade of raw ore is high and the yield of concentrate is high, the amount of tailings will be small. If a large amount of tailings are not handled properly, it will be very harmful. The tailings water discharged from the concentrator often contains a large amou...

AI Technical Summary

Problems solved by technology

[0005] In the process of tailings treatment, the tailings must first be dehydrated. The tailings and other materials have undergone preliminary dehydration treatment, and the moisture content can only reach 50%-65%, but it cannot meet the requirements of tailings processing.

If you want to further reduce the moisture content of the material through further pressure filtration, it is very difficult, and there are also problems such as long time for pressure filtration, ineffective water rate, and large energy consumption.
