Description

Filter bag for dust cleaner

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter bag for a dust collector, and more particularly, to a filter bag for a dust collector which is easy to replace a filter cloth by fixing a cylindrical filter bag having a wrinkle shape to a retainer so as to maintain its shape by a connecting support.

BACKGROUND ART [0002] Generally, a dust collecting apparatus is a general term for a device for removing dust such as solids floating in the air or liquid fine particles, and includes an air inlet through which air containing dust is supplied, a filter through which the introduced air passes, And an air injecting device for injecting high-pressure air into the filter to remove the accumulated dust, wherein the filter is disposed in the air inlet, The dust not passing through the fine mesh of the filter cloth supported by the retainer is configured to fall downward or to be laminated on the filter cloth.

In the filter constructed as described above, a phenomenon occurs in which dust adheres to the filter cloth of the filter over time, so that not only the pressure loss is rapidly increased but also the filtration efficiency is lowered. Therefore, A dust removing operation is performed to remove dust adhering to the filter cloth through air pulsing.

The air exhausting through the air pulsing strongly injects air in the lower end direction through the inside of the filter at the upper end of the filter cloth to remove the accumulated dust by the compressed air and remove the accumulated dust by the vibration of the filter cloth generated by the injection of the compressed air However,

Conventionally, in the filter, a support for supporting a filter cloth is inserted into a filter bag, which is usually formed in a cylindrical shape, and the upper and lower ends of the filter cloth are integrally fixed to the upper and lower caps by a resin binder Therefore, when the air cleaning operation is performed by the air pulsing, the filter bag is hardly vibrated by the compressed air, so that the cleaning efficiency is lowered.

Particularly, when a large amount of dust is adhered to the surface of the filter cloth by a predetermined time, it is difficult to efficiently remove the dust by only the filter operation by air filtering. However, in the conventional filter, the filter cloth, the upper cap and the lower cap are integrally fixed Thus, when the efficiency of the filter cloth is lowered, the entire filter must be replaced.
