Problems solved by technology

[0009] However, when the membrane housing cannot be formed into a cylindrical shape, such as when the membrane element is formed in a non-cylindrical shape such as a prism, if a cylindrical filter housing with a diameter larger than that of the membrane element is used, there may be The following problem: the membrane part becomes large, not only the installation area increases, but also the equipment cost increases
Therefore, it is impossible to adopt a structure that adjusts the threaded state between the filter housing main body and the filter housing cover, and there is a problem that a predetermined area of ​​the filter main body cannot be fixed in a watertight manner.

Embodiment Construction

[0058] Hereinafter, the membrane case, the membrane member, and the membrane module having the membrane member of the present invention will be described.

[0059] exist figure 1 2(a) to (d) illustrate the membrane module 1 composed of the membrane member 20 of the present invention. Membrane module 1 comprises: four membrane parts 20; Raw water header 22, it supplies raw water to each membrane part 20; Cleaning header 24, it supplies cleaning air or water, medicinal liquid to each membrane part 20; The pipe 26 collects the filtered water of each membrane unit 20 .

[0060] Each membrane member 20 is composed of a membrane case 100 and a membrane element 2 housed in the membrane case 100. The membrane case 100 is composed of a base 30, a case body 40, an upper cover 50, and a frame supported by the case body 40. The supporting part 60 and the holding part 70 etc., the holding part 70 can adjust the relative position between the supporting part 60 and the upper cover 50 along...

Abstract

A membrane casing for watertightly accommodating a membrane element (2) for filtering raw water, comprising: a cylindrical casing main body (40) for accommodating the membrane element (2); a cover (50), It is configured to fit into the opening end of the case body (40), and to ensure watertightness between the case body (40) and the case body (40) so as to be able to follow the direction of the case body (40) while maintaining the posture. Axial movement; pressing mechanism (60, 70), which presses and holds the membrane element (2) accommodated in the housing body (40) by pressing the cover (50), wherein the membrane housing is of a simple structure Even if the membrane case cannot be formed into a cylindrical shape, it can absorb the dimensional variation of the membrane element and fix it watertightly with a predetermined pressing force.

Description

technical field [0001] The present invention relates to a membrane case that accommodates a membrane element for filtering raw water in a watertight manner via a sealing member, and a membrane component that accommodates the membrane element in the membrane case. Background technique [0002] Patent Document 1 discloses a filter cartridge which is a membrane member in which a cylindrical filter main body is accommodated. The filter box has a filter housing, that is, a membrane housing, and the filter housing includes: a cylindrical filter housing main body, which accommodates the filter main body; The threaded part formed on the inner peripheral part of the end part of the main body of the device is screwed together. [0003] This membrane component is configured by accommodating a filter body with sealing members arranged up and down in a filter case body, and fastening a filter case cover screwed to the filter case body so that a predetermined area of ​​the filter body is...
