Solid-liquid separation disc filtering system

Abstract

The invention relates to a solid-liquid separation disc filtering system, which comprises a central support (1), a filter disc (2), a hollow shaft (5), filter cloth (3) and a suction disc (4), wherein the filter disc (2) and the hollow shaft (5) are arranged on the central support (1); the filter cloth (3) is arranged on the filter disc (2); the hollow shaft (5) can rotate; and the suction disc (4) is arranged on the hollow shaft (5) and can contact the filter cloth (3). In the disc filtering system, when the filter cloth is washed, the filter disc is fixed steadily, but the suction disc rotates; and this design makes the entire filtering system more energy-saving. In addition, the design of an independent water outlet pipe allows a signal filter unit to be replaced without cutting off water and the working condition of each filter unit to be monitored. Meanwhile, the modularized filter disc makes the entire filtering system more flexible.

Description

technical field [0001] The invention relates to a disc filter system for solid-liquid separation in the field of sewage treatment. Background technique [0002] The increasing shortage of water resources and the continuous development of social economy make the recycling of water resources more and more important. In order to further remove the suspended solids in the sewage and achieve the purpose of advanced treatment and recycling, an efficient sewage treatment equipment for solid-liquid separation is needed. [0003] Patent No. 200720173409.9 provides a fiber turntable filter tank for advanced sewage filtration treatment. The tank body is composed of a sewage tank and a clean water tank, which are connected to each other. The hollow water outlet shaft is fixed in the sewage tank and connected to the transmission mechanism. The rotary filter disc is relatively fixed to the hollow water outlet shaft through the hexagonal connector, and the outer ring of the rotary filter ...

AI Technical Summary

Problems solved by technology

The filter disc is installed on the central drum, and the driving motor drives the central drum to rotate. The driving force required is relatively large, and all equipment is installed underwater. If maintenance is required, it needs to be shut down and the water cut off, which is inconvenient for maintenance

At the same time, the rotary filter disc itself is heavy, and it is connected with the hollow water outlet shaft. The rotary filter disc rotates at the same time during suction, which requires a large driving force, which limits the overall length of the rotary disc system and causes unstable operation.
