Problems solved by technology

[0002] At present, the suction port used for dust collection on the inner surface of the dust cage is horseshoe-shaped or slit-shaped, and the suction port is in radial partial contact with the filter material, and the suction port has radial partial adsorption during the process of vacuuming the inner surface of the dust cage, causing the filter bag to shake , so that the fine dust trapped on the inner surface of the filter bag falls and settles in the lower part of the dust cage, especially the dust with a larger specific gravity settles more seriously, the filter bag is deformed, and the cleaning efficiency is low, resulting in a large ventilation resistance of the filter material, which will cause the filter material to harden and fail for a long time , and even cause the problem of damaging the suction port or puncturing the filter bag

Embodiment Construction

[0027] see Figure 1~Figure 3 , the present invention is an annular suction nozzle applied to the inner surface of the dust cage, which includes a support cylinder 1 and a front plate 3, and the front plate 3 is fixedly arranged on the front side of the support cylinder 1 through a connecting piece. An annular slit suction port 4 is formed between the cylinder 1 and the front disc 3 .

[0028] The support cylinder 1 comprises a horizontal section 1.1 and an inclined section 1.2 forming a flare 1.3.

[0029] The center of the front plate 1 is provided with a diversion cone 5 inwardly, through the function of the diversion cone 5, the ventilation resistance of the suction nozzle itself can be reduced, and the cone angle of the diversion cone 5 is 100-130°.

[0030] The connecting piece is a plurality of spacer blocks 2 uniformly arranged along the circumference, and the spacer block 2 is fixedly arranged on the front side of the inclined section 1.2, and the front plate 3 is fi...

Abstract

The invention relates to a ring-shaped suctioning nozzle applied in dust suctioning on the internal surface of a dust cage and belongs to the technical field of dust removing equipment. The ring-shaped suctioning nozzle comprises a supporting drum (1) and a front disc (3), wherein the front disc (3) is fixedly arranged at the front side of the supporting drum (1); and a ring-shaped slotted suctioning port (4) is formed between the supporting drum (1) and the front disc (3). The ring-shaped suctioning nozzle has the advantages that fine dusts on the internal surface of the dust cage can be thoroughly cleared and suctioned by one time, no rolling is caused to the fine dust, and no damage is caused to filtering materials, so that the efficiency and the effect of dust suctioning are greatly improved.
