Filter case

Abstract

A filter housing is provided to mount a filter cartridge on an inner part of a container body in a easy and stable manner. A filter housing comprises a container body(1) and a head(2). The container body is used in a state that a cylindrical filter cartridge is longitudinally inserted into the container body. The upper end of the container body is opened. The head functions as a cover of the container body. The head includes two flow paths for introducing and discharging liquid to be treated. The container body and head are sealed by a pair of toggle clamps(4) in a state that a ring-shaped member(3) is interposed between the container body and head. Supporting part of the toggle clamps are diagonally positioned on an upper outer surface of the container body. Hooks(7) and handle levers(10) are vertically mounted on the supporting parts such that the hooks are positioned on upper portions of the supporting parts and handle levers are positioned on lower portions of the supporting parts. A guide unit(5) is installed between the container body and ring-shaped member to position the container body and head on the same axial line.

Description

technical field [0001] The present invention relates to a filter case which can always install a filter box stably and reliably, and which can be easily installed even in complicated circuits. Background technique [0002] In recent years, in various chemical industries, water treatment industries, painting industries, etc., in order to quickly filter the fluid flowing in the lines, filter devices are often installed and used in the flow paths. Therefore, the development of a filter case, which is a filter device in which a filter case is installed inside and a liquid to be treated passes through the filter case to filter impurities, has been confirmed in many cases. [0003] However, in the middle of compact and complicated lines, etc., there is no device that can handle with good operability, and it is required that the filter box can be easily and reliably installed in any place, and the cleaning inside the device is also easy. device development. [0004] Therefore, fo...

Problems solved by technology

[0003] However, in the middle of compact and complicated lines, etc., there is no device that can handle with good operability, and it is required that the filter box can be easily and reliably installed in any place, and the cleaning inside the device is also easy. development of the device

[0004] Therefore, for example, Patent Document 1 discloses a filter case in which a filter cartridge can be installed without using a central shaft, but this device needs to use a guide member (a guide member provided on the inner peripheral surface of the case) inside the container main body. The ring-shaped convex strip 22) clamps the filter box, which cannot effectively use the entire surface of the filter box, and the flow of the liquid inside the container is also damaged due to the existence of the guide parts

[0005] In addition, the upper end of the container main body and the head, and the lower end of the container main body and the bottom member are respectively connected by splints 9, and it takes time to attach the filter box to the container main body and to assemble the container main body, the head, and the bottom member with good airtightness. The less operable way of
