Efficient sludge drying treatment device

Abstract

The invention discloses an efficient sludge drying treatment device. The efficient sludge drying treatment device comprises a casing, wherein support legs are bilaterally symmetrically arranged at the bottom of the casing; a screen is arranged in the casing and is inclined; a vertical rod is hinged with the bottom end of the left side of the screen; the bottom end of the vertical rod is fixed at the bottom in the casing; a feeding port is formed in the position, above a guide plate, of the top end of the right side of the casing; a cushion block is fixed at the bottom of the right end of the screen; a rotary cam is arranged below the cushion block. The efficient sludge drying treatment device is novel in structure; with ingenious arrangement of the screen and a screen vibration drive mechanism, dehydration efficiency is greatly improved, meanwhile, scrapers are arranged above the screen and perform reciprocating motion, and sludge on the screen is turned over vertically, so that the dehydration and drying efficiency is further improved; a pair of extrusion rolls is further arranged and used for thoroughly dehydrating and drying the sludge; a discharging mechanism is arranged to facilitate discharging.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-efficiency sludge drying treatment device. Background technique [0002] With the continuous improvement of my country's urbanization level, the construction of sewage treatment facilities has developed rapidly. According to the "2013-2017 China Sludge Treatment and Disposal In-depth Research and Investment Strategic Planning Analysis Report" statistics, in 2010 my country's urban sewage treatment plants have built 2500 The urban sewage treatment capacity has reached 122 million tons per day, which has made great contributions to the realization of the country's emission reduction goals and improvement of the water environment. However, the construction and operation of the sewage plant will produce a large amount of excess sludge. Based on the water content of 80%, the total annual sludge water production in the country will soon exceed 30 millio...
