Lining band type filter press with press rolls for fixing mud

Abstract

The invention discloses a lining belt type pressure filter with a solid mud press roller. The press filter comprises a stander, a driving device, a feeding device, a press area and an auxiliary device, and has the structure that the press area comprises the solid mud press roll, a carrier roller, a guide roller, a filtering stripe and a compression lining belt; the solid mud press roller is a press roller with a solid mud layer covering the surface of the roller, and the solid mud layer adopts the material which has high elasticity, high recoverability, and high fraction coefficient, and is easy to separate from dehydrate material; the solid mud press roller is provided with a maintenance device, which is arranged behind the press position of the solid mud press roller, and the elasticity and the fraction coefficient of the solid mud layer can be recovered in time through the maintenance to the solid mud press roller by the maintenance device; the filtering stripe wraps the solid mud press roller, the carrier roller and the guide roller in sequence; the compression lining belt and the filtering stripe are stacked in parallel in the press segment of the press area; the driving device drives filtering stripe and the compression lining belt; and the feeding device and the auxiliary device are arranged in the corresponding positions of the filtering stripe. The pressure filter of the invention has solid mud structure, thereby effectively solving the problem of mud leaking and achieving better press filter effect.

Description

technical field [0001] The invention relates to a belt-type filter press, in particular to a belt-type filter press with a solid mud press roller, which is specially used for industrial waste water, pulp, domestic sludge, oily sludge, etc. Solid-liquid separation of particle suspension or solid-liquid mixed waste. Background technique [0002] Belt filter presses are widely used as solid-liquid separation equipment for various wastes produced in water treatment plants, paper mills, food processing plants, chemical plants and farms. These wastes are squeezed, filtered and dehydrated by a belt filter press, concentrated and then landfilled or used for comprehensive utilization, which is more beneficial than direct disposal. Therefore, improving the discharge dryness and production efficiency of the belt filter press is directly related to the high efficiency, environmental protection and economy of the final disposal and utilization of these wastes. The applicant disclosed i...

Problems solved by technology

However, the filter press uses a polyester flat-woven filter belt. When the pressing pressure used in the pressing area increases, and the polyester flat-woven filter belt cooperates with the press roller to squeeze and dewater the sludge, the polyester flat-woven filter belt will The gap is small, there is no three-dimensional layer, and the water is filtered slowly. After the mud layer is pressed, it will squeeze to both sides of the filter belt, resulting in mud running. normal operation
