Sliding compression continuous solid-liquid separator

Abstract

The invention relates to a sliding compression continuous solid-liquid separator. Solid-liquid separation equipment capable of adapting to dehydrating adhesive and slippery materials and running continuously is absent at present. The sliding compression continuous solid-liquid separator comprises a frame, a feeding device, a lower filter belt, a squeezing area and a driving device, and is characterized in that: the squeezing area comprises an upper compression device and a lower compression device; the upper compression device comprises at least one upper compression unit comprising an upper compression block, an upper left compression roller, an upper right compression roller and an upper sliding rubber belt; the upper sliding rubber belt coats and winds the upper left compression roller, the upper compression block and the upper right compression roller; the lower compression device comprises a lower compression block, a lower left compression roller, a lower right compression roller and a lower sliding rubber belt; the lower sliding rubber belt coats and winds the lower left compression roller, the lower compression block and the lower right compression roller; the upper compression device is positioned over the lower compression device; a gap is formed between the upper compression device and the lower compression device; and the height of the gap is gradually reduced froman inlet to an outlet. The sliding compression continuous solid-liquid separator is reasonable in structural design and high in solid-liquid separation efficiency, and can adapt to dehydrating the adhesive and slippery materials and continuously operates.

Description

Technical field [0001] The invention relates to a solid-liquid separator, in particular to a sliding pressurized continuous solid-liquid separator, belonging to a high-pressure strong solid-liquid separation device, which is mainly suitable for sewage treatment plants, paper mills, food processing plants, chemical factories and Dehydration of micro-particle liquid-containing materials in farms. Background technique [0002] Water treatment plants, paper mills, food processing plants, chemical plants and breeding farms all produce a large amount of materials that need to be dehydrated. These materials are dehydrated, concentrated and then landfilled, which can save a lot of land and reduce sewage penetration. At the same time, many organic materials in these materials can be directly used for comprehensive utilization when they are concentrated to a certain solid content, thereby saving drying Dry energy, for example, when the solid content of paper-making deinking sludge is pres...

Problems solved by technology

[0004] 1. Due to the hydraulic reciprocating pressurization, only intermittent operation can be adopted, and the tape running, pressing and unloading must be carried out step by step, so the efficiency is low

In addition, because of the intermittent operation, it is difficult to uniform the cloth, which leads to different pressing effects.

[0005] 2. Since the pressing pressure is completely provided by the hydraulic cylinder, and the stroke of the hydraulic cylinder is limited, the number of filter plates of each equipment is difficult to compare with the traditional box-type filter press. For example, the ordinary plate-type filter press can achieve 100 plates. Above, and the utility model is generally about 10 boards, which is very unfavorable to increase production and reduce equipment cost

[0006] In terms of high dehydration pressure of continuous operation filter press equipment, if the publication date is December 20, 2006, the publication number is CN1879932, and the Chinese patent No. 200610050778.9 discloses "a belt filter press". The filter press uses a steel rope belt to provide high tension to increase the dehydration pressure. The dehydration pressure is as high as 3.0Mpa, which has made substantial progress in increasing the solid content of materials with high friction such as primary sludge filter cake; but , for materials with sticky and slippery properties, such as municipal activated sludge, such a high pressing pressure will inevitably lead to side slipping of materials and difficulty in feeding, making it difficult to implement effective pressing

[0007] To sum up, there is currently no solid-liquid separation equipment that can adapt to the dehydration of sticky and slippery materials and operate continuously, which brings great inconvenience to the separation of sticky and slippery materials
