Clamping-type reverse osmosis membrane housing

Abstract

The invention discloses a clamping-type reverse osmosis membrane housing, relates to the technical field of water treatment, and solves the technical problem of inconvenience for washing and replacing filter materials. The membrane housing comprises a housing body and a membrane housing cover, wherein the housing body is filled with a reverse osmosis membrane assembly; a circle of neck ring is arranged on an outer wall of the housing body; an opening part at a top end of the housing body is movably sleeved with the membrane housing cover, and the membrane housing cover is locked and fixed through a locking sleeve ring; a circle of step is arranged on the outer wall of the membrane housing cover; upper and lower side edges of the locking sleeve ring are bent inwards and press against the step on the outer wall of the membrane housing cover and the neck ring on the outer wall of the housing body respectively; two four-connecting-rod mechanisms are arranged on the locking sleeve ring in an axial symmetry manner; the locking sleeve ring is formed by combining two detachable half ring parts; each four-connecting-rod mechanism comprises a lock latch and a lock core, the lock latch is pivoted on one half ring part, and the lock core is pivoted on the other half ring part and pivoted with the lock latch of the mechanism through a pin shaft. The membrane housing provided by the invention is suitable for reverse osmosis filters of water treatment products.

Description

technical field [0001] The invention relates to water treatment technology, in particular to a technology of snap-fit ​​reverse osmosis membrane shells. Background technique [0002] At present, people pay more and more attention to their health, especially the requirements for drinking water are getting higher and higher. Reverse osmosis water purifier products can allow people to drink healthy and safe purified water in the form of terminal purification, and are becoming more and more popular in people's daily life. [0003] The water purifier product and the core processing unit - the reverse osmosis membrane is generally made into a roll membrane structure according to the actual needs of use. The reverse osmosis membrane is often placed in a component called a membrane shell. The bottom of the membrane shell is provided with a clean water discharge port and a concentrated water discharge port, and the top is covered by a membrane shell. Due to reasons such as installa...

Problems solved by technology

[0004] At present, the common membrane shell structure in the market, the membrane shell and the membrane shell cover are connected by threads. When installing and replacing, you need to use a matching special wrench to unscrew the membrane shell cover. Although the structure is simple, the replacement operation is not easy. convenient

Furthermore, on the one hand, the thread part bears the pressure of the water inside the filter, and on the other hand, it also bears the pre-tightening force applied to the sealing ring. The tightening degree of the thread is also affected by the manufacturing accuracy, and cannot be reliably quantified and controlled. Influenced, resulting in unreliable sealing performance, or excessive pre-tightening stress of the thread, causing fatal damage to the structure, the service life of the entire membrane shell is unpredictable, and there is a serious hidden danger of water leakage
