Abstract

The invention discloses a belt press filter for superfine and strong viscous materials, and relates to an improvement on the structure of a belt press filter. The invention provides the belt press filter which has compact structure and is more suitable for superfine and strong viscous materials. The belt press filter comprises a frame, and an electric cabinet and a pneumatic control cabinet are arranged on the frame. The belt press filter is structurally characterized in that: a sludge delivery pipe with a feeding hole is arranged above the frame, a pair of vertically engaged identical gears is arranged on the lateral side of the frame, the gears are driven by chains on chain wheels of a motor, and an upper press roller and a lower press roller are arranged on the shafts of the pair of gears respectively; a water catcher is arranged below an upper filter strip below an output port, and the bottom of the water catcher is provided with a drain pipe; an upper scraping plate and a lower scraping plate are arranged outside the upper press roller and the lower press roller respectively; and two ends of a rotary arm are arranged on a frame shaft and a piston rod of a cylinder of the frame respectively, and the rotary arm is provided with a movable press roller capable of touching a strong press roller.

Description

Technical field: [0001] The present invention relates to an improvement in the structure of a belt press filter. Background technique: [0002] At present, in the treatment equipment of sewage sludge (such as urban domestic sewage, sludge, mining sewage, sludge, and sewage and sludge in metallurgical industry) in the environmental protection industry, belt filter press is characterized by its low cost and convenient use and maintenance. , and can achieve continuous operation and other characteristics, has been widely used. However, there are also the following defects: the pre-pressing section of the original belt filter generally adopts a large-diameter pre-pressing roller, because the ultra-fine and viscous materials have strong fluidity and are easy to be extruded during pre-pressing materials; therefore, It is not suitable for ultra-fine and viscous materials. Invention content: [0003] The present invention is aimed at the above problems, and provides a belt press ...
