Sludge high-pressure belt type deep dehydrator and application method thereof

Abstract

The invention provides a sludge high-pressure belt type deep dehydrator, which comprises a main body frame, an upper filter belt and a lower filter belt, wherein a feeding module, a filter pressing module and a discharging module are arranged in the main body frame, the filter pressing module is arranged between the feeding module and the discharging module, the feeding module comprises a uniform distribution mechanism, the uniform distribution mechanism is arranged above the lower filter belt, a feeding opening is formed above the uniform distribution mechanism, the filter pressing module comprises pressing rollers and a squeezing mechanism, the squeezing mechanism comprises a low-pressure area and a high-pressure area, a plurality of pressing rollers are distributed in the low-pressure area and the high-pressure area, a large-roller-diameter pressing roller and a small-roller-diameter pressing roller are arranged in the filter pressing module through bearings, the upper filter belt and the lower filter belt are wound on the pressing rollers, the large-roller-diameter pressing roller and the small-roller-diameter pressing roller respectively, the discharging module comprises a discharging device and a flushing mechanism, and the working surface of the flushing mechanism covers the working surfaces of the upper and lower filter belts. According to the invention, the problems of complex process flow, poor dehydration effect, low sludge treatment capacity, high investment cost, high labor cost and high operation cost of the existing sludge dehydration equipment are solved.

Description

technical field [0001] The invention relates to a sludge high-pressure belt-type deep dewatering machine, in particular to a sludge high-pressure belt-type deep dewatering machine and an application method thereof. Background technique [0002] With the acceleration of urbanization and the continuous improvement of people's living standards, the public is paying more and more attention to environmental issues, and the requirements for environmental quality are also increasing. Most cities in my country have built centralized urban domestic sewage treatment plants. However, sewage treatment technology A large amount of pollutants in the sewage are transferred to the remaining sludge, and the sludge output of the sewage treatment plant increases sharply, and the problem of water pollution is converted into a problem of solid waste treatment and disposal. [0003] Sludge dewatering actually refers to the removal of interstitial water in sludge. Interstitial water is easy to rem...
