Embodiment Construction

[0026] In the present invention, the orientation words used such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "inside and outside" refer to the outline relative to each part itself inside and outside.

[0027] For ease of understanding, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] see figure 1 , figure 2 , figure 1 It is the unfolded view of the filter cloth of the present invention. The middle part mainly matches the size of the concave part of the plate frame (that is, the bottom of the filter chamber). The filter cloth 1 is composed of two layers, namely the filter cloth body and the mesh cloth , wherein the filter cloth body is on the upper surface, which is in contact with the mud cake in the filter chamber, and plays the role of filtration and heat resistance. The filter cloth is made of nylon monofilament filter...

Abstract

The invention provides a special cloth filter for electroosmosis sludge high-dryness dewatering equipment, which comprises a cloth filter body and a mesh fabric arranged under the cloth filter, wherein the cloth filter body and mesh fabric constitute the cloth filter; the upper surface of the cloth filter body contacts a sludge cake; and the mesh fabric contacts a sealing surface of a filter cell. Compared with the conventional cloth filters, the cloth filter provided by the invention has the characteristics of simple structure, heat resistance, wear resistance, long service life, favorable sealability, reliable operation and the like, and is convenient for disassembly and assembly and also convenient for material removal. The special cloth filter can lower the sludge water content and save the power consumption by 10kwh per ton of sludge, and the service life is prolonged by 2-3 times as compared with the common cloth filters.

Description

technical field [0001] The invention relates to the field of sludge disposal equipment components, in particular to a solid-liquid separation device for electroosmotic sludge high-dry dehydration equipment [0002] Set filter cloth. Background technique [0003] The high-dry electroosmotic sludge dewatering equipment can meet the requirements of deep dehydration, drying and final disposal of sludge, and achieve the goals of sludge reduction, harmlessness and resource utilization. Increase the dehydration efficiency by 2-3 times, and the moisture content of the sludge after dehydration can be reduced from 80% to below 40%. Since there is no chemical agent added, there is almost no loss of organic matter in deep dewatered cakes, and the calorific value is high, which is especially suitable for incineration. [0004] However, in actual use, it is found that ordinary 750B series filter cloths have disadvantages such as heat resistance, partial material removal, and low service...
