Description

Filtering device

The present invention relates to a filtration device, and more particularly, to a filtration device that self-cleans a filter during operation of the filtration device, and can be used without replacement of the filter and no separate cleaning process.

In general, when a plurality of different foreign substances are mixed in a sample, a filtering device is used to separate each foreign matter.

That is, particles of various sizes or foreign substances present in the liquid or gas have a problem of impairing the purity of the sample or failing to exhibit the original function of the sample. Therefore, in order to increase the purity of the sample, a filtration device having a filter is provided between the inlet and the outlet of the apparatus to filter the particles.

However, in the above-described filtration apparatus, a filter having various sizes of filtration holes is used in order to filter particles of a few um in size from particles of a few millimeters in size which can be visually recognized. The foreign matter is adsorbed to the filtration hole of the filter, and the adsorbed foreign substance blocks the flow of the sample, and after a certain time, the filter can no longer be used.

In order to solve such a problem, conventionally, a method of replacing a filter or performing a separate cleaning process to remove foreign matter adsorbed is used, but this has disadvantages of adding cost, consuming time and manpower.
