Fiber pressure filter equipment

Abstract

The invention provides a fiber pressure filter device, which consists of a shell, a water inlet pipe, a filter assembly, a water outlet pipe, a bypass valve, a backwash assembly and a transmission assembly. It is connected with the sewage area. The filter assembly and backwash assembly installed in the sewage area are composed of multiple monomers. The filter assembly is installed on the partition and communicates with the clean water area through three hollow connecting pipes. The backwash assembly is installed vertically. On the bottom plate, the upper end is fixed by a bearing installed on the top cover, and the lower end is connected with the transmission mechanism. The invention has the advantages of compact structure, high space utilization rate, less land occupation; thorough backwashing and cleaning; long service life; the number of filters can be adjusted flexibly, and it is also convenient for multiple sets to be combined, and is applicable to large, medium and small water treatment.

Description

technical field [0001] The invention relates to a fiber pressure filter device, which belongs to the technical field of water treatment. It is suitable for the upgrading of urban sewage treatment plants, the filtration of suspended solids in the reclaimed water treatment process, and the filtration of circulating water in swimming pools. Background technique [0002] Among the existing pressure filtration equipment, the filtration equipment using quartz sand as the filter material is still the mainstream. The characteristics of this filter equipment are that the filter material is arranged horizontally, and the direction of water flow can only be filtered in one direction. Its disadvantages are: the filtration area is small and occupies The ground area is large, the water head loss is large, the energy consumption of backwashing is large, the service life of the filter material is short and easy to be lost, and the installation and maintenance are inconvenient. The equipment...

Problems solved by technology

[0002] Among the existing pressure filtration equipment, the filtration equipment using quartz sand as the filter material is still the mainstream. The characteristics of this filter equipment are that the filter material is arranged horizontally, and the direction of water flow can only be filtered in one direction. Its disadvantages are: the filtration area is small and occupies The ground area is large, the water head loss is large, the energy consumption of backwashing is large, the service life of the filter material is short and easy to be lost, and the installation and maintenance are inconvenient. The equipment is not only expensive, but also the treatment cost is high."

[0003] In addition, in the existing fiber rotary disc filters using fiber as the filter medium, due to the limited diameter of the center water outlet shaft, when the number of filter discs is large and the processing capacity is increased, the water outlet flow rate in the center water outlet shaft is too high, and the water flow resistance The larger the water outlet, the central water outlet shaft may also be bent and deformed; secondly, the space utilization rate is not high, and the floor area of ​​the pool body is relatively large; when backwashing, it drives the entire filter disc to rotate, which requires high power and is not easy to clean. Thorough; equipment is open and not suitable for pressure filtration
