Abstract

The invention discloses a belt sludge treatment press filter, and relates to an improvement of a structure of a belt filter. The belt sludge treatment press filter has small volume and compact structure, and provides a pressed sludge with low water content. The belt sludge treatment press filter comprises a frame. An electric cabinet and a pneumatic control cabinet are arranged on the frame. The key points of the structure are as follows: the top of the frame is provided with a sludge transport pipe with a medicine inlet; the side of the frame is provided with a pair same gears arranged aboveand below, wherein the gears are driven through a motor, and shafts of the pair gears are respectively provided with an upper press roller and a lower press roller; an upper filter belt of the upper press roller passes through an outlet of the sludge transport pipe in the frame, bypasses a pre-press roller and a press roller, and is returned to the upper press roller; an lower filter belt of the lower press roller bypasses an intermediate roller, and is superposed with the upper filter belt on the pre-press roller, then bypasses the press roller, and is returned to the lower press roller; a water collecting tank is arranged below the upper filter belt arranged below the outlet, and the bottom of the water collecting tank is provided with a drain pipe; the upper press roller and the lower press roller are respectively provided with an upper scraper and a lower scraper.

Description

Technical field:

[0001] The present invention relates to the improvement of the belt filter structure. Background technique:

[0002] At present, among the treatment equipment for sewage sludge (for example: urban domestic sewage, sludge, mine sewage, sludge, sewage and sludge in the metallurgical industry) in the environmental protection industry, the belt filter press is low in cost and easy to use and maintain. , and can achieve continuous operation and other characteristics, has been widely used. But there are also the following defects: 1. The equipment is bulky, expensive, and occupies a large area; 2. The moisture content of the squeezed sludge is still high. Invention content:

[0003] The present invention aims at the above problems and provides a belt-type sludge treatment press filter with small volume, compact structure and low moisture content of the sludge after pressing.

[0004] In order to achieve the above-mentioned purpose of the present invention, the...
