Continuous sludge treatment system

Abstract

The invention relates to a continuous sludge treatment system. The system comprises a dehydrating rack, wherein a pre-dehydration device is arranged on the dehydration rack; the pre-dehydration deviceis provided with a sludge inlet and a pre-dehydrated sludge outlet; a filter press is arranged at the pre-dehydrated sludge outlet; the pre-dehydrated sludge outlet is communicated with the feeding opening of the filter press; and a filter pressing adjusting mechanism is arranged in the filter press, a filter pressed sludge outlet is formed in the filter press, a sludge collecting tank is arranged at the filter pressed sludge outlet in a communicating manner, a sludge conveying pipeline is arranged in the sludge collecting tank, the free end of the sludge conveying pipeline is communicated with a drying device, and a material receiving hopper is arranged at the material outlet of the drying device. The pretreatment dehydration treatment device and the drying device are arranged, and the filter pressing adjusting mechanism is additionally arranged in the filter press, so that the removal efficiency of water of the sludge is improved from multiple positions, the load of the belt filterpress is reduced, and finally the water content of the discharged sludge is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a continuous sludge treatment system. Background technique [0002] The main sludge dewatering equipment in my country's current market is the plate and frame filter press, belt filter press, and centrifugal extrusion dewatering machine. The water content of the sludge produced by the machine equipment in my country's existing sewage system is in the range of 75-90%. The high water content has caused the difficulty in the follow-up disposal of sludge in my country's sludge disposal industry. However, the frame design of the current belt filter press is not reasonable enough, and it is not easy to maintain, and the parts in contact with water are prone to rust after a period of use. The treatment capacity of filter press sludge is small, and the filter screen will be clogged after a period of use. [0003] In view of the above problems, the Chinese patent with the public...

AI Technical Summary

Problems solved by technology

[0004] The above scheme still has the following disadvantages. After the sludge is simply flocculated, it is directly sent to the belt filter press for dehydration. When the sludge is squeezed by the above-mentioned mesh belt roller, the sludge itself has a large water content, resulting in The dewatering load of the belt filter press increases, and the dehydration of the filter press is not sufficient, which eventually leads to a low dryness of the sludge, which cannot meet the existing market requirements for high sludge dryness.
