Description

Upper cap for dust collector filter

The present invention relates to an upper cap for a dust collector filter, and in particular, to easily combine and separate a cap and a lower portion of a filter structure used in a dust collector, the filter production process is simplified, and the cap can be recycled after use. It relates to an upper cap for the dust collector filter.

The contents described below merely provide background information related to the present invention and do not constitute a prior art.

The dust collector is a kind of air purifier, and after filtering a gas containing dust or the like, it is a device for flowing back into the room or discharge to the outside.

The general structure of the dust collector is composed of an intake chamber, an exhaust chamber, an intake port, an exhaust portion, a plurality of cartridge filters coupled to the tube sheet hole, a compressed air supply pipe, a spray nozzle, and the like.

The intake chamber and the exhaust chamber in the housing are separated by partition walls.

The gas introduced into the intake chamber through the intake port is moved to the exhaust chamber after dust and the like are filtered out by the plurality of cartridge filters. Gas moved to the exhaust chamber is introduced into the room or exhausted through the exhaust unit.

The dust collector is provided with a plurality of dust filters. The dust collecting filter needs to have heat resistance to withstand the heated gas, and the surface area is made as wide as possible to increase the filtering efficiency. One filter having a large surface area is a cartridge filter.

1 is a view showing a conventional cartridge filter in a combined state, Figure 2 is a view showing an exploded state of a conventional cartridge filter.

1 and 2, the conventional cartridge filter is a cartridge filter bag 10, fabric bands (21, 22, 23), upper and lower caps (31, 32), adhesives (41, 42), support net ( 50).

The cartridge filter bag 10 is formed with a plurality of peaks and valleys to increase the surface area.

One or more fabric bands 21, 22, 23 are coupled around the outside of the cartridge filter bag 10. The fabric bands 21, 22, 23 maintain the appearance of the cartridge filter bag 10 and suppress deformation of the cartridge filter bag 10 when high pressure compressed gas is applied to the cartridge filter bag 10.
