Description

Filter structure for dust collector which consists of functional venturi integrally

The present invention relates to a filter structure for a dust collector, and in particular, to improve the structure of the venturi to improve the dust removal ability to shake off the accumulated dust on the filter surface, hide the visible parts and improve the design to increase the value and easy assembly One filter assembly, and relates to a filter structure for a dust collector comprising a functional venturi integrally strengthening the coupling force between the venturi and the filter.

In general, the dust collector is installed in various industrial processes in which a large amount of dust or dust is generated to collect and separate fine dust and contaminants in the air by a filter.

In the dust collector's filter, when dust used in a factory or work site is used for a long time, dust accumulates on the filter cloth or the surface of the filter, which causes a slow flow rate of the filter, an increase in pressure loss, and poor air discharge. There was a problem that the dust collecting function of the filter is poor.

Therefore, the dust collector should remove dust accumulated in the filter to maintain the performance of the dust collector. The method of removing accumulated dust is to spray compressed air through a pulse device in a short time and spray a large amount of compressed air with a certain time or a certain condition to shake off when the filter is pressurized. By applying pressure (jet air) inside the filter, dust is released and discharged through the lower discharge device.

When the dust collector continuously performs the dust collection function of the filter, a venturi is installed between the nozzle and the inlet of the filter for efficient exhaustion and delivery of a strong and large amount of compressed air to the filter surface.

Venturi is a component that increases the flow rate by converting the pressure energy of the air injected from the nozzle into kinetic energy.

Such venturi increases the effect of increasing the flow rate of sucking the ambient air at a pressure lowered by Bernoulli's law.
