High-pressure belt type sludge deep dehydration system

Abstract

The invention discloses a high-pressure belt type sludge deep dehydration system which comprises a discharging mechanism, a first filter pressing belt and a second filter pressing belt partially overlapped with the first filter pressing belt, and the discharging mechanism is located above the first filter pressing belt. According to the system, under the cooperative action of a first adjusting device and a second adjusting device, the tightness of the first filter pressing belt and the second filter pressing belt can be adjusted, when the system is in a shutdown state, the first filter pressing belt is in a stagnation state, and a rotating roller is also in a static state, so that a connecting seat in the rotating roller is in a static state, a pull wire cannot be pulled under the action of inertia, the pull wire is in a loose state, the loosened pull wire cannot lift a wire pressing shaft, so that under the action of a rotating shaft, a belt pressing roller at one end of a rocker arm cannot press the first filter pressing belt, the first filter pressing belt is in a loosened state, the first filter pressing belt is prevented from being placed in a tensioned state all the time, and the first filter pressing belt can be well protected.

Description

technical field [0001] The invention belongs to the related technical field of dewatering systems, and in particular relates to a high-pressure belt-type sludge deep dewatering system. Background technique [0002] The further dehydration of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%. Dehydration methods mainly include natural drying method, mechanical dehydration method and granulation method. Natural drying method and mechanical dehydration method are suitable for sewage sludge. The granulation method is suitable for coagulation and sedimentation of sludge. The sludge produced by sewage treatment has a high water content. Due to the combination of water and sludge particles, mechanical removal has certain limitations. The sludge in the sludge Organic matter content, ash ratio and especially the amount of flocculant added have an important influence on the final solid content. Generally speaking, the solid content of 20%-30%...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-pressure belt-type sludge deep dewatering system to solve the problem that when the high-pressure belt-type sludge dewatering equipment proposed in the above-mentioned background technology stops working, the filter press belt on the equipment is still in a tensioned state, and the filter press belt When it is in a tensioned state for a long time, it will cause damage to the filter press belt, and the existing high-pressure belt sludge dewatering equipment cannot automatically adjust the tightness of the filter press belt according to the actual situation during the working process
