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 reliable sliding pressurization mechanism for solid-liquid separation equipment that can adapt to the dehydration of sticky and slippery materials and operate continuously, thus reducing the performance of solid-liquid separation equipment and also affecting the separation efficiency. Sticky and slippery materials bring great inconvenience

Abstract

The invention relates to a slide pressurizing mechanism used in a slide pressurizing continuous solid-liquid separating machine, wherein no slide pressurizing mechanism has reliable performance at present. The slide pressurizing mechanism comprises an upper pressing device and a lower pressing device; the upper pressing device comprises at least one upper pressing unit; the upper pressing unit comprises an upper pressing block, an upper left pressing roller, an upper right pressing roller and an upper slide adhesive tape; the upper pressing block is positioned between the upper left pressing roller and the upper right pressing roller; the upper slide adhesive tape is twisted outside the upper left pressing roller, the upper pressing block and the upper right pressing roller; the lower pressing device comprises a lower pressing block, a lower left pressing roller, a lower right pressing roller and a lower slide adhesive tape; the lower pressing block is positioned between the lower left pressing roller and the lower right pressing roller; the lower slide adhesive tape is twisted outside the lower left pressing roller, the lower pressing block and the lower right pressing roller; the upper pressing device is positioned right above the lower pressing device; a gap is formed between the upper pressing device and the lower pressing device; and the gap height is gradually reduced from the inlet to the outlet. The slide pressurizing mechanism has reasonable structure design and high solid-liquid separation efficiency, and is applicable to the dewatering of sticky and smooth materials with continuous operation.

Description

technical field [0001] The invention relates to a sliding pressurization mechanism, in particular to a sliding pressurization mechanism used in a sliding pressurization continuous solid-liquid separator, which belongs to a part of the sliding pressurization continuous solid-liquid separator. Background technique [0002] Water treatment plants, paper mills, food processing plants, chemical plants and 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 infiltration; at the same time, when many organic materials in these materials are concentrated to a certain solid content, they can be directly used for comprehensive utilization, thereby saving drying. Dry energy, such as when the solid content of deinking sludge from papermaking is dried to more than 50%, can be incinerated without supplementary fuel, and its incineration residue can be used ...
