Vacuum filter with filter-pressing function

Abstract

The invention discloses a vacuum filter with a filter-pressing function, and belongs to the technical field of filter machinery. The technical problem to be solved is to provide a filter which has high filtering and dehydrating performance and can perform deep dehydration on hydrophilic materials. The technical means adopted for solving the technical problem is that a filter system comprises a vacuum rotary drum, first filter cloth and second filter cloth, wherein one end of the first filter cloth is connected with the other end of the first cloth to form a closed ring after bypassing the vacuum rotary drum and a plurality of first guide rollers; one end of the second filter cloth is connected with the other end of the second cloth to form a closed ring after bypassing the vacuum rotary drum and a plurality of second guide rollers; on the part contacted with the vacuum rotary drum, the second filter cloth covers the first cloth filter to form a filter interlayer; the first filter cloth and the second filter cloth move in the same direction; the first filter cloth is separated from the second filter cloth on the top part of the vacuum rotary drum; after the first filter cloth is separated from the second filter cloth, the first filter cloth is provided with a horizontal section to serve as a material conveying section. The vacuum filter with the filter-pressing function can be widely applied to the technical field of material dehydration.

Description

technical field [0001] The invention discloses a vacuum filter with a filter press function, which belongs to the technical field of filter machinery. Background technique [0002] With the increase of the population, the domestic waste is increasing day by day, and a large amount of urban domestic sludge and sludge from cleaning rivers and lakes are produced. In recent years, more and more attention has been paid to the treatment of sludge, and corresponding plans have been issued in many regions. And regulations, for example, Shanghai has issued special regulations to supervise the treatment of sludge. The sludge generated from cleaning rivers and lakes is mainly buried or made into building materials. In addition to the above-mentioned methods for domestic sludge treatment, sludge with high organic content can also be dried and incinerated. Regardless of the method of treatment, the sludge needs to be dehydrated. The main dehydration method at present is to dry the sludg...
