Abstract

The invention relates to a dewatering and drying device belonging to the technical field of dewatering and drying treatment. The dewatering and drying device is characterized by comprising a base, a pressure piston, pressure-withstanding sleeves and a dual-layer filter screen mechanism, wherein a dual-layer filter screen is arranged on the base and the pressure-withstanding sleeve is connected to the dual-layer filter screen, the pressure piston is arranged on the pressure-withstanding sleeve oppositely and provided with a pressure tongue, and a pushing hydraulic cylinder is connected to the pressure piston. The dewatering and drying device has the advantages of simple structure, large compression pressure, short compression time, low compression water content, convenience for treatment, rapidness in maintenance, low operation cost, capability of massive array-forming type operation, high production efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of dehydration and drying treatment, and relates to a dehydration and drying device. Background technique [0002] At present, there are many kinds of equipment for mud-water separation, including plate and frame filter press, hydrocyclone, electric energy dryer, etc. Among them, the plate and frame filter press is the most widely used. The plate and frame filter press is composed of many partitions with permeable holes, and the compression power is air pressure. [0003] Disadvantages and limitations of plate and frame filter press: [0004] 1) The pretreatment process is complex [0005] The plate and frame filter press requires uniformly mixed mud to enter. The undisturbed soil excavated from rivers and seas not only needs to be cleaned of impurities, but also needs to be mixed and stirred with equipment to make the undisturbed soil evenly mixed so that it can enter the equipment. conditions of.
