Ultrasonic sludge wall breaking device

Abstract

An ultrasonic sludge wall breaking device relates to the technical field of sludge treatment and comprises an upper box cover, a middle box body and a lower box body which are sequentially connected from top to bottom, a blanking opening is formed between the middle box body and the lower box body; the upper surface of the upper box cover is fixedly connected with a feeding hopper communicated with the three-section wall breaking box; the box wall of the lower end of the lower box body is gradually shrunk downwards, and a discharging opening is formed in the lower end of the lower box body; a collecting box is arranged between the vertical supporting plates, and an opening is formed in the upper end of the collecting box and is opposite to the discharging opening; a plurality of ultrasonic transmitters are arranged in the middle box body; a filter screen cylinder is arranged in the middle box body, and a rotary stirring mechanism is arranged in the filter screen cylinder; and a grinding cylinder is arranged between the rotary stirring mechanism and the blanking port. The sludge wall-breaking treatment device solves the problems of low dehydration wall-breaking efficiency, poor treatment effect, high residual quantity of harmful substances, complex structure, high energy consumption and high cost of the existing sludge wall-breaking treatment device during sludge wall-breaking treatment in the prior art.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an ultrasonic sludge wall breaking device. Background technique [0002] With the rapid development of cities, the amount of sludge that needs to be treated increases sharply every year, the sludge composition is complex, the moisture content is high, the treatment cost and product value are not proportional, and it is easy to cause secondary pollution. main problem. [0003] The activated sludge process is the most widely used sewage biological treatment technology in the world, but its disadvantage is that it will produce a large amount of excess activated sludge. These excess activated sludge usually contain a certain amount of toxic and harmful substances (such as parasite eggs, pathogenic microorganisms, heavy metals, etc.) and unstabilized organic matter. If not properly treated and disposed of, it will cause direct or potential damage to the environment. Polluti...
