Description

Dust collector using centrifugation and filter {Collector by Centrifugation and Filter}

The present invention relates to a dust collector using centrifugal separation and a filter, and more particularly, to a dust collector using a centrifugal separation and filter configured to remove foreign substances and automatically clean the filter using centrifugal separation and filter.

In general, the operation of mechanically separating liquid or solid particles suspended in the air stream from the air stream is called dust collection, and the device used for dust collection is called a dust collector.

The dust collector may be divided into a gravity dust collector, an inertial dust collector, a centrifugal dust collector, a cleaning dust collector, a filter dust collector, an electric dust collector, a sonic dust collector, and the like by a separation force or separation mechanism acting on the particles.

In the filter and dust collector, a method of separating particles while passing a gas containing particles such as dust through a filter (filter material) is widely used. The filter used in the filter and dust collector is composed of paper, fiber, metal, or synthetic resin network.

On the other hand, in the filter and dust collector, when particles such as dust are accumulated on the surface of the filter, the air permeability of the gas is lowered, the dust collecting performance is lowered, and related parts such as a pump for generating an air flow are easily damaged or damaged.

Therefore, in order to maintain dust collection performance, to prevent breakdown or damage of related parts, and to extend the life of the filter, it is recommended to clean the filter frequently to remove the accumulated particles.

However, in order to clean the filter, disassembly and assembly of the filter or related parts are required, which is cumbersome and more difficult to clean frequently.
