High-dryness filter and method

Abstract

The invention relates to a high-dryness filter and a method. The high-dryness filter comprises a cylinder body, a hydraulic cylinder and two crossbeam binders, wherein a plurality of foot box binders are welded on the bottoms of the two crossbeam binders respectively; lateral box binders are arranged at the positions, which are close to both ends, on the tops of the two crossbeam binders; the bottoms of the lateral box binders are welded on the two crossbeam binders respectively; guide rails are arranged at the positions, which are close to middle parts, on the two crossbeam binders; the cylinder body is arranged above the guide rails; the front and rear sides of the cylinder body are provided with a plurality of cylinder body support binders respectively; the bottoms of the cylinder body support binders are arranged on the guide rails through wheels; a fixed piston on the left side of the cylinder body is connected with the lateral box binder on the left side through welding; and a movable piston on the right side of the cylinder body is connected with a hydraulic rod of the hydraulic cylinder. The high-dryness filter has the advantages that: the solid content of mud cakes is improved, the automation degree is extremely high, and the energy consumption is extremely low; and the moisture content of the mud cakes is low, the mud cakes are convenient to transport and treat, and the aim of drying, and the aims of emission reduction and innocent treatment are also fulfilled.

Description

technical field [0001] The invention relates to a high dryness filter and a method. Background technique [0002] The main function of the filter press is to separate the solid-liquid mixture. Existing filter presses are mainly divided into traditional plate-and-frame (or box-type) and belt-type. The plate-and-frame filter press requires manual operation, which is labor-intensive, cannot withstand high pressure, and is easy to burst the frame. The belt filter press uses the pressure between the filter belt and the roller or the pressure belt to filter the solid-liquid mixture on the filter belt. Although the filtration is continuous, the filter pressure cannot be too high because both sides of the filter belt are open. In order to prevent the material to be filtered from being extruded from both sides of the filter belt, the solid-liquid separation after filtration is not ideal. After the separation of the above two equipments, the water content is as high as 80%. This kin...

Problems solved by technology

Existing filter presses are mainly divided into traditional plate-and-frame (or box-type) and belt-type. The plate-and-frame filter press requires manual operation, which is labor-intensive, cannot withstand high pressure, and is easy to burst

The belt filter press uses the pressure between the filter belt and the roller or the pressure belt to filter the solid-liquid mixture on the filter belt. Although the filtration is continuous, the filter pressure cannot be too high because both sides of the filter belt are open. To prevent the material to be filtered from being extruded from both sides of the filter belt, so the solid-liquid separation after filtration is not ideal

After the separation of the above two equipments, the water content is as high as 80%. This kind of sludge needs to be reprocessed. The treatment cost is very high, and the sludge pollutes the environment and cannot be disposed of. The filter cake after filtration is difficult to separate from the filter cloth
