Chemical filter replacement device and replacement method

Abstract

The objective of the present invention is to provide a chemical filter replacement device and replacement method which can prevent a chemical from leaking to the outside when a chemical filter is being replaced, minimize the risk of accidents that may occur when the chemical filter is being replaced, and make the volume of the device compact, and also reduce the labor required to replace the chemical filter. To this end, the chemical filter replacement device (1) of the present invention comprises: a filter assembly mounting portion (300) in which a filter assembly (2) is mounted, wherein the filter assembly (2) comprises a first cartridge (10-1) to be used for filtration of a chemical or a second cartridge (10-2) that has been used for filtration of the chemical, and a filter housing (20) and a filter head (30) that receive the first cartridge (10-1) or the second cartridge (10-2) and are coupled to each other vertically; and a cartridge replacement means configured such that when the filter housing (20) is separated from the filter assembly (2) in a state where the filter assembly (2) is mounted on the filter assembly mounting portion (300), the second cartridge (10-2) is separated from the filter assembly (2), and then the first cartridge (10-1) is coupled to the filter assembly (2) from which the second cartridge (10-2) is separated, the cartridge replacement means couples the separated filter housing (20) to the filter assembly (2).

Description

Technical field [0001] The present invention relates to a chemical filter replacement device and a replacement method, and more particularly to a chemical filter replacement device and replacement method of a filter that can easily replace the impurities of the impurity contained in the filter chemical. Background technique [0002] Generally, a company, pharmaceutical companies, and paint companies, manufacturers, pharmaceutical companies, and paint companies, etc., all companies that use hazardous chemicals are using various types of chemicals, and safely supply such chemicals is also become become Various. [0003] Such chemicals are supplied by chemical filters to use high-purity states that minimize impurities depending on the characteristics of the manufacturing process. [0004] The chemical filter is also different depending on the shape and replacement method thereof, and various replacement cycles are held according to the type of chemical and the desired high purity st...

Problems solved by technology

[0006] However, in the case where a worker manually replaces the chemical filter, chemicals and fumes (FUME) may leak to the outside during the chemical filter replacement work, thereby polluting not only the surrounding environment including the manufacturing equipment, damage, vandalism, and other workers, including those around them, may be exposed to danger

[0007] In addition, in the case of the staff's valve operation error, various toxic chemicals inside the filter may leak to the outside.

[0008] In addition, since chemical filters are replaced manually, there is a problem that the number of work steps required for filter replacement increases
