Problems solved by technology

However, the conventional hollow ultrafiltration membrane module manufacturing method is to fix the hollow ultrafiltration membrane filament and the membrane shell with epoxy resin to form an integral hollow ultrafiltration membrane module. The ultrafiltration membrane filament and the membrane casing are discarded at the same time
However, engineering plastics are the most used materials for membrane shells, which will cause waste of material costs and secondary pollution to the environment.
[0003] During the use and operation of the integral ultrafiltration membrane module, the hollow ultrafiltration membrane filament is easily polluted, resulting in a decrease in the permeation flux of the membrane filament, and even making the membrane module unusable and difficult to clean
hampers its wide application in practical use

Embodiment approach 1

[0021] Embodiment 1, the diameters of the water outlet 15 and the water inlet 14 are set to be consistent with the diameters of the clean water outlet 12 and the raw water inlet 11 , and the openings with the same diameters can be docked during implementation.

Embodiment approach 2

[0022] Embodiment 2, the diameter of the mouth of the water outlet 15 and the water inlet 14 is set to be larger than the diameter of the mouth of the purified water outlet 12 and the raw water inlet 11, so that the water outlet 15 and the water inlet 14 can be sleeved on the purified water outlet 12 and the raw water inlet 11, and the front end of the water outlet 15 and the water inlet 14 is against the fixed block provided in the end cover 2, and in specific implementation, the water outlet 15 and the water inlet 14 are set outside the clean water outlet 12 and the raw water inlet 11, and the outlet The front ends of the water inlet 15 and the water inlet 14 are respectively against the fixed blocks on the end cover 2 .

Abstract

The invention discloses an ultrafiltration membrane component which comprises a pressure-bearing shell and an ultrafiltration membrane group, wherein the ultrafiltration membrane group is movably assembled in the pressure-bearing shell; the pressure-bearing shell comprises a membrane pipe, two end covers respectively arranged at the two ends of the membrane pipe, and fasteners for connecting the membrane pipe and the end covers; one end of the ultrafiltration membrane group is provided with a water inlet, and the other end of the ultrafiltration membrane group is provided with a water outlet; the end cover at one end of the membrane pipe is provided with a raw water inlet, and the end cover at the other end of the membrane pipe is provided with a purified water outlet; the water inlet is connected with the raw water inlet in a detachable way; the water outlet is connected with the purified water outlet in a detachable way. With the technical scheme, the ultrafiltration membrane component has the advantages that the ultrafiltration membrane group is simple and easy to replace, and the replacement cost is reduced; when being seriously polluted, the ultrafiltration membrane group can be cleaned outside the ultrafiltration membrane component, and pollutants and blockages on the surface of membrane silk can be thoroughly cleaned.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an ultrafiltration membrane module. Background technique [0002] Today, with the rational use of water resources and the strengthening of environmental protection, hollow ultrafiltration membranes have been widely used in various fields as a membrane water treatment equipment. However, the conventional hollow ultrafiltration membrane module manufacturing method is to fix the hollow ultrafiltration membrane filament and the membrane shell with epoxy resin to form an integral hollow ultrafiltration membrane module. Ultrafiltration membrane filaments and membrane shells are discarded at the same time. However, engineering plastics are mostly used as the material of the membrane shell, which will cause waste of material costs and secondary pollution to the environment. [0003] During the use and operation of the integral ultrafiltration membrane module, the hollow ultrafiltration membr...
