Sludge purification and dehydration device

Abstract

The invention discloses a sludge purification and dehydration device which comprises a screen drum, a stirring chamber, a squeezing chamber and a mounting rack. A transmission mechanism is fixedly arranged at the top of the mounting rack and can drive the screen drum to rotate. The screen drum is movably arranged at the top of the mounting rack through a rolling mechanism, and the screen drum canrotate relative to the mounting rack through the rolling mechanism. A plurality of screen holes are formed in the screen drum in a circumferential array mode, and a plurality of arc-shaped guide plates are arranged on the inner wall of the screen drum in a circumferential array mode. Through the arrangement of the screen drum, impurities and medical wastes in a sludge mixture can be separated, andthe normal sludge treatment progress of the whole device can be prevented from being influenced by the blockage phenomenon in the sludge treatment process. Through the arrangement of a sealing coverand a plasma gas purifier, the device has excellent sealing performance, it can be ensured that odor is not leaked in the sludge treatment process, and air pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of hospital sludge treatment, and in particular relates to a sludge purification and dehydration device. Background technique [0002] Hospital sewage is generally composed of sewage discharged from places including wards, outpatient rooms, laboratories, laboratories, canteens, bathrooms, toilets, reagent rooms, laundry rooms, etc. The sewage contains a large number of bacteria, viruses, parasites and chemical agents , also contains many organic and inorganic pollutants, such as various drugs, disinfectants and other pollutants. The composition is relatively complex and has the characteristics of space pollution, acute infection and latent infection. [0003] The sludge produced with raw sewage treatment also contains a large number of bacteria, viruses, parasites and chemicals. If the sludge containing pathogenic microorganisms is not effectively disposed of, it will cause serious pollution to the surroundi...

AI Technical Summary

Problems solved by technology

[0003] The sludge produced with raw sewage treatment also contains a large number of bacteria, viruses, parasites and chemicals. If the sludge containing pathogenic microorganisms is not effectively disposed of, it will cause serious pollution to the surrounding waters and soil, causing Various diseases and infectious diseases seriously endanger people's health

[0004] Moreover, the existing hospital sludge treatment device cannot separate impurities in the hospital sludge mixture: such as medical masks, plastic bags and other impurities, which may easily cause blockage of the device and affect the normal sludge treatment progress of the entire device
