Description

Flat membrane assembly of cartridge type bundling combined modular structure Technical Field The utility model belongs to a filtering device for solid-liquid separation, and particularly relates to a flat membrane assembly with a plug-in type bundling combined modular structure. Background Waste water containing suspended matters and solid particles is produced in the production process of industrial and mining enterprises such as metallurgy, chemical industry, building materials, electric power, mining and the like, and the main means for purifying the waste water is to separate a solid-liquid mixture by a filtering mode. Currently, fine filter media commonly used are various organic and inorganic membranes. The hollow flat membrane has wide application in terms of its structural mode. The hollow flat membrane is a plate-like structure in which a membrane layer is coated on the outer surface and a plurality of through holes are arranged in the width direction and penetrate the longitudinal direction. In practical application, both ends of the flat membrane are closed by plugs, and a tubular interface is arranged on the plug at one end of the flat membrane, and a central hole of the interface is communicated with the inner hole. The interface of each flat membrane is connected with a water collecting pipe through a quick connector, and then the water collecting pipe is connected with a system water main. The flat membrane with the structure forms a filtering unit, and is only suitable for operation under negative pressure suction. During back flushing, the pressure water of the main pipe is shunted to each flat membrane through the water collecting pipe, the phenomena of uneven distribution and large resistance exist, the water quantity and the pressure of back flushing are limited, and the back flushing effect of the membranes is poor. The installation workload of a membrane plate and an interface on site is quite large. In order to overcome the above drawbacks, the present inventors have disclosed a flat membrane module of a nested cluster modular structure in patent number 201920582719.9.
