Abstract

The invention discloses a reduction dehydration device for sewage sludge. The reduction dehydration device comprises at least one dehydration module. Each dehydration module comprises a bidirectional oil cylinder (1) and two symmetric dehydration units (2). Each dehydration unit (2) comprises a dehydration barrel (2.1), a supporting plate (2.2) and an extruding plate (2.3). The supporting plates (2.2) are located on the outer sides of the dehydration barrels (2.1), and the extruding plates (2.3) are located on the inner sides of the dehydration barrels (2.1). Feeding ports (2.4) are formed in the dehydration barrels (2.1). Each bidirectional oil cylinder (1) is provided with two piston rods (1.1) which are connected with the extruding plates (3) of the two corresponding dehydration units (2) respectively. According to the reduction dehydration device, feeding dehydration and squeezing dehydration are carried out at the same time, so that work efficiency is improved; meanwhile, the pressure of fed materials is ingeniously utilized for dehydration in the squeezing dehydration process, so that the power use effect is improved, and product energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of sewage sludge treatment, in particular to a sewage sludge reduction and dehydration device. Background technique [0002] Sludge is the product of sewage treatment. At present, a large amount of sludge produced after sewage treatment needs further treatment, and dehydration is an important part of sludge treatment. Its purpose is to remove most of the water in the sludge and make the solids highly enriched. , significantly reduce the volume of sludge to save the cost of sludge treatment, increase the calorific value of sludge and save energy, which is of great significance for the reduction and subsequent disposal of sludge. Mechanical dehydration is the most effective dehydration method with the least energy consumption. Currently, deep dehydration of sludge by conditioning and mechanical methods can generally make the moisture content reach 80%-60%. [0003] Mechanical dehydration methods and equipment mainly in...
