Abstract

The invention belongs to the technical field of sludge dewatering, and provides an efficient energy-saving sludge deep dewatering device. The device comprises a first-stage dewatering system for extrusion dehydration, a second-stage dewatering system for drying and dehydration and a condensing device. The first-stage dewatering system and the second-stage dewatering system are arranged side by side. Two sides of the first-stage dewatering system are provided with a first feeding inlet and a first discharge outlet. The top of the second-stage dewatering system is provided with a second feedinginlet and the bottom is provided with a second discharge outlet. The first discharge outlet is connected to the second feeding inlet through a sludge transfer pipe. A sludge lifting pump is arranged in the sludge transfer pipe. The bottom of the second-stage dewatering system is provided with a condensed water outlet, the condensed water outlet is connected to a condensing unit through a condensing pipe. The condensing unit is connected to the first-stage dewatering system. The device can condense and collect water steam produced by the second-stage dewatering system, feed the water into the first-stage dewatering system to backwash a first-stage filter belt so that holes of a first-stage filter belt of the first-stage dewatering system are not blocked through sludge during the process ofextruding the sludge. The pores of the grade filter belt.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering, in particular to a high-efficiency and energy-saving deep sludge dewatering device. Background technique [0002] At present, the most common sludge dewatering equipment is the Filter Press Machine. The filter press type sludge dewatering machine has the advantages of high sludge moisture content, fast filtration speed and suitable for chemical sludge treatment methods. The existing method for sludge dewatering using a filter press type sludge dewatering machine is as follows: firstly, the filter plates are compressed by an oil pressure device, and a filter chamber capable of filtering sludge is formed between the filter plates; The mud pump pumps the sludge from the sludge storage tank to the filter chamber until the filter chamber is filled with sludge; then, the water in the sludge is squeezed by the pressure difference formed by the filter cloth on the filter plate in the filter ch...
