Description

Technical Field

[0001] The utility model belongs to the field of dust removal equipment, in particular to a flat bag dust removal device. Background Art

[0002] As people pay more and more attention to the environment, the country's requirements for dust removal in various places are becoming more and more stringent, which makes people's demand for dust removal equipment greater and higher. Common dust removal and filtration devices are mostly dust-containing air entering from one side of the filter, and clean air passing through the other side of the filter, through multi-stage coordination to achieve thorough dust removal, but this dust removal method has low dust removal efficiency, small processing capacity, and inconvenient filter cleaning. When cleaning, dust clumps or dust blocks are likely to affect the filter next to it, causing secondary pollution, and the equipment is complex and has high power requirements. For this reason, people hope to find a dust removal and filtration device with high dust removal efficiency, large processing capacity, and convenient filter cleaning. Utility Model Content

A transmission belt is provided on the bottom, and the bottom of the outermost rotating shaft is also connected to a rocker arm driven by a cylinder so as to be driven to rotate thereby. Through the transmission action of the transmission belt, the remaining rotating shafts can be driven to rotate by the rocker arm at the same time as the outermost rotating shaft, so as to achieve the effect of shaking the supporting frame to clean the dust collecting flat cloth bag. A plurality of air inlet channels are provided on the lower part of the dust collecting box body, and the air inlet channels are connected with the external space of the dust collecting flat cloth bag at the bottom. An induced draft channel is provided on the upper part of the dust collecting box body, and the induced draft channel is connected with the internal space of the dust collecting flat cloth bag at the top, and an induced draft fan is also provided on the induced draft channel.

[0006] Preferably, a dust-containing air pre-separation baffle is provided inside the dust removal box and at the outlet of the air inlet channel, so that heavy particles can touch the pre-separation baffle first and fall down first, thereby achieving the effect of pre-filtration of dust-containing air.

[0007] Preferably, a dust collecting and discharging device is provided at the bottom of the dust removal box and below the flat dust removal bag.

[0008] More preferably, the dust discharge device is a screw extrusion mechanism.

[0009] Preferably, four dust removal flat cloth bags are provided in the dust removal box.

[0010] The beneficial effects of the utility model are:

[0011] The flat cloth bag dust collector of the utility model has an ingenious structure. During dust removal, dust-laden air enters from the outside of the dust removal flat cloth bag and exits from the upper inside of the dust removal flat cloth bag. The dust-laden air enters from the bottom, which can give coarse particles a pre-sedimentation effect, thereby preventing them from directly contacting the dust removal flat cloth bag and polluting and blocking the dust removal channel of the dust removal flat cloth bag. In addition, by using the dust removal flat cloth bag, space can be saved, the filtering surface area can be increased, and the filtering efficiency can be improved. By driving the supporting frame to swing back and forth, the supporting frame can be made to beat and shake the dust removal flat cloth bag, so as to achieve the effect of automatically loosening and falling off the dust cakes or dust accumulated on the surface of the dust removal bag to complete the automatic cleaning. The dust cleaning efficiency is high, time and labor saving is saved, and the practicability is strong, and it is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS
