Backwashing microfiltration water treatment device

Abstract

The invention relates to a backwashing microfiltration water treatment device which comprises a tank body, a rack, a filtering component and a backwashing mechanism, wherein the filtering component comprises multiple filtering units which are distributed at an interval; each filtering unit comprises multiple filter pipes, a brackets, a water outlet end and a backwashing end; multiple filter pipesare distributed in an array manner, and the two ends of the filter pipes are embedded into fixed plates respectively; sealed bulges are reversely buckled to the externals of the fixed plates respectively, one end of each sealed bulge is formed with the corresponding water outlet end and is communicated with a water collection cavity on the rack, and the other end of each sealed bulge is the corresponding backwashing end and is connected with the backwashing mechanism; each bracket supports between the corresponding water outlet end and the corresponding backwashing end to form a whole body; and sewage which flows into the tank body is filtered with the filter pipes from outside to inside, gathers in the water collection cavity and is drained with a clear water hole unifiedly. The backwashing microfiltration water treatment device has the characteristics of reasonable design, simple structure, simple and convenient operation and high filtering efficiency; and by arranging multiple groups of filtering units in the tank body, under the condition without shutdown, local filtering units alternately perform backwashing operation is realized, and smoothness of a filtering flow rate is ensured.

Description

Technical field: [0001] The invention belongs to the field of water treatment equipment, and in particular relates to a backwash microfiltration water treatment device, in particular, it can wash partial filter membrane groups in turn without stopping the machine. Background technique: [0002] Water treatment, especially physical filtration treatment, is an effective method that is needed in various fields, including drinking water treatment, aquaculture water recycling, and sewage harmless treatment, all of which cannot be separated from the link of water filtration. Regardless of whether it passes through a screen or a permeable membrane, there is a problem that plugging will affect the filtration efficiency, and the backwashing scheme is also the most common method. [0003] For example: Patent Application No. 201711007839.8, which discloses a membrane filtration device with ultrasonic cleaning and a sewage purification system. This kind of membrane filtration equipment...

AI Technical Summary

Problems solved by technology

Due to the limited transmission range of ultrasonic vibration, the rotating machinery drives the filter to rotate, making the structure complicated. Moreover, the filter must stop filtering during the cleaning process, and multiple interactive operations are required to ensure the continuity of water supply or water treatment.
