Membrane column using novel upper flange and pressing sleeve

Abstract

The invention belongs to the field of water treatment, and particularly relates to a membrane column using a novel upper flange and a pressing sleeve, which comprises a membrane shell, a central pull rod, a plurality of flow guide discs with O-shaped rings, an upper flange and a lower flange which are arranged on the two ends of the central pull rod, and is characterized in that the upper section of an inner hole of the upper flange is sealed with the central pull rod, a space is reserved between the lower section of the inner hole of the upper flange and the center pull rod, the pressing sleeve and a disc spring are installed in the space, the bottom end of the pressing sleeve presses the O-shaped ring of the flow guide disc, the disc spring is arranged at the top end of the pressing sleeve, and the inner wall of the pressing sleeve and the center pull rod are sealed. According to the invention, the prior patent structure is improved, the installation is convenient, the overall weight is reduced, and the defects of instability, even failure and the like in the operation of the prior patent product are avoided.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, in particular to a membrane column using a novel upper flange and a compression sleeve. Background technique [0002] The present invention is an improvement on the applicant's previous patent "A Membrane Assembly with a Pre-tightening Force Compensation Mechanism for an O-ring O-ring of a Baffle" with the patent number ZL 202020252316.0. The purpose of this patent is the same as that of the previous patent. They both solve the problem that when the membrane column is working, the central tie rod will be stretched under force, resulting in a reduction in the compression of the O-ring installed on the guide plate, and the pull rod will change instantaneously when the pressure changes. However, the response speed of the deflector and the sealing ring to the deformation is much slower than that of steel, which leads to deformation or misalignment of the deflector and the O-ring, resulting in...

AI Technical Summary

Problems solved by technology

The purpose of this patent is the same as that of the previous patent. They both solve the problem that when the membrane column is working, the central tie rod will be stretched under force, which will reduce the compression of the O-ring installed on the deflector plate, and the tie rod will change instantaneously when the pressure changes. However, the response speed of the deflector and the sealing ring to the deformation is much slower than that of steel, which leads to deformation or misalignment of the deflector and the O-ring, resulting in the performance degradation or even damage of the membrane column.

[0003] However, in actual production, the applicant found that the previous patent had a series of problems such as complex structure, increased weight, and difficulty in installation, and the membrane column of the above-mentioned patented structure, compared with the lower pressure membrane column, had a series of problems such as product operation failure, so this patent proposed A new structure to solve the above problems
