Water purifying device and filtering module thereof

Abstract

The present invention relates to a water purifying device and a filtering module thereof. The filtering module comprises a plurality of filtration unit columns, wherein every two adjacent filtration unit columns are connected through a positioning plate. Each filtration unit column comprises: a top overflowing pipe; a plurality of filtering membrane assemblies arranged in the length direction of the top overflowing pipe, wherein the upper ends of the filtering membrane assemblies communicate with the top overflowing pipe, each filtering membrane assembly is provided with a first through cavity, the adjacent first through cavities are connected together, the lower ends of the filtering membrane assemblies are provided with second through cavities and air inlet channels communicating with the second through cavities, and the adjacent second through cavities are connected together; and a bottom supporting piece, which is provided with an air channel used for being connected with an external air source and connectors with a number identical with the number of the air inlet channels, wherein the connectors correspond to the air inlet channels in a one-to-one mode, and the connectors connect the air inlet channels to the air channel. The bottom supporting pieces not only play a role in supporting the filtering unit columns, but also serve as air supply pipelines, so redundant air conveying pipelines are saved, the size of the filtering module is reduced, and a structure is simpler.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water purification device and a filter module thereof. Background technique [0002] In the application of water treatment technology, conventional filtration modules generally include water inlet pipes, product water pipes, concentrated water pipes, and some devices also include air inlet pipes. The layout of the main pipeline and branch pipelines of the whole filtration module is complicated. In addition, the frame of the filter module is also complicated in structure due to the complexity of the pipeline, which is unfavorable for the manufacture, installation and use of the filter module, and cost reduction. Contents of the invention [0003] Based on this, it is necessary to provide a filter module that facilitates the simplification of the pipeline structure and the frame structure of the filter module. [0004] A filter module, comprising a plurality of filter...
