Blind-end-free membrane shell

Abstract

The invention belongs to the technical field of fluid filtration, and particularly relates to a blind-end-free membrane shell. The blind-end-free membrane shell comprises a shell, a reverse osmosis membrane and an end cover, wherein the shell is of a cylindrical structure with an opening in one end; the end cover is assembled at one end of the shell in a sealed mode. A first positioning rod is arranged in the middle of the inner wall of the other end of the shell; the middle part of the end cover extends into the shell and is provided with a hollow second positioning rod corresponding to the first positioning rod; a concentrated water outlet is formed in the side wall of one end of the shell; One end, deviating from the shell, of the end cover is provided with a pure water outlet communicated with the interior of the shell and a raw water inlet connected and communicated with the second positioning rod, the reverse osmosis membrane is assembled in the shell, and the first positioning rod and the second positioning rod are respectively inserted into the two ends of the pure water flow channel in the middle of the reverse osmosis membrane in a sealing manner. The blind-end-free membrane shell has the advantages of reasonable structural design, uniform scouring of water flow in the shell, no dead cavity structure and good filtering effect.

Description

technical field [0001] The invention belongs to the technical field of fluid filtration, in particular to a membrane shell without a blind end. Background technique [0002] Existing membrane shells all go in and out from top to bottom, and the flow of water in the membrane shell is uneven. There are dead spaces in the membrane shell. If the space is too large, the water flow cannot pass through the membrane shell evenly, resulting in no water flow in the back area of ​​the water outlet. [0003] In addition, the length of the existing membrane shell is too long, the upper and lower sides need to be supported by brackets, and the bracket itself will also have dead space, which will lead to the growth of bacteria. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a membrane shell without blind ends, which effectively overcomes the defects of the prior art. [0005] The technical scheme that the present invention s...

[0002] Existing membrane shells all go in and out from top to bottom, and the flow of water in the membrane shell is uneven. There are dead spaces in the membrane shell. The space is too large, and the water flow cannot pass through the membrane shell uniformly, resulting in no water flow in the back area of ​​the water outlet

[0003] In addition, the length of the existing membrane shell is too long, and the upper and lower sides need to be supported by brackets, and the bracket itself will also have dead space, which will lead to the growth of bacteria
