Technical Field

The invention relates to the technical field of bag dust collectors, in particular to a low-noise pulse dust collector.

Background technique

Bag dust collector is a very common dust removal equipment in industrial production process. Bag dust collector sends dusty air into the dust collector box through the air inlet pipe, and captures fine, dry, non-fibrous dust through dust bags. The filtered dust falls into the ash hopper for collection, and the filtered air is discharged into the atmosphere.

After the existing bag-type dust collector has been used for a period of time, a large amount of dust will adhere to the outside of the dust bag, resulting in a decrease in the overall air outlet efficiency of the device and an increase in the overall noise of the dust collector. Therefore, the dust collector needs to be cleaned regularly to improve processing efficiency and reduce equipment noise. In the cleaning process of the prior art, the equipment needs to be shut down for cleaning. After the staff disassembles the entire device, they use pulse airflow to reversely flush the dust bags so that the dust adhered to the outside of the dust bags is blown out, making the air inlet pores of the dust bags unobstructed. During the cleaning process, the entire equipment needs to be shut down, and the staff cleans each dust bag one by one.

In a natural state, the cleaning rod 2 is in a bent state under the pull of the connecting frame. When the guide rod 15 falls from the ascending guide groove into the annular guide groove, the guide rod 15 pulls the intermediate rod 14 and the pull rod 13 upward, so that the middle part of the cleaning rod 2 protrudes outward, hitting the dust cloth 3, thereby cleaning the dust cloth 3.

Instructions:

When the device is in use, external air enters the device housing 1 through the air inlet pipe 5, and the air is filtered by the dust removal cloth 3 and then discharged to the outside through the exhaust pipe 6.

During the process of filtering the air, the driving motor 10 drives the supporting plate 11 to rotate. During the rotation of the supporting plate 11, the guide rod 15 moves along the guide groove on the supporting plate 11.

When the guide rod 15 moves along the 3/4 annular guide groove, the pull rod 13, the intermediate rod 14 and the support rod 16 do not move;

When the guide rod 15 enters the 1/4 ascending guide groove along the 3/4 annular guide groove, the upper end of the guide rod 15 pushes the outer end of the intermediate rod 14 upward, the intermediate rod 14 pulls the pull rod 13 downward, and the pull rod 13 pulls the middle part of the cleaning rod 2 toward the axial direction of the dust removal part;

When the guide rod 15 leaves the 1/4 rising guide groove and enters the 3/4 annular guide groove, under the action of gravity and the compression spring 21, the lower end of the guide rod 15 is quickly pressed downward, and the guide rod 15 quickly lifts the pull rod 13 upward through the middle rod 14, and the upper end of the pull rod 13 quickly pops out the middle part of the cleaning rod 2, so that the cleaning rod 2 hits the dust removal cloth 3 that is concave inwardly, so that the dust removal cloth 3 quickly changes from being concave inwardly to being convex outwardly, and the dust outside the dust removal cloth 3 is knocked off;

Repeat the above-mentioned actions. During the filtering process of the dust cloth 3, the dust cloth 3 is continuously hit by the cleaning rod 2 and the widening plate 17 to prevent excessive adsorption of dust on the outside of the dust cloth 3. At the same time, due to the setting of the widening plate 17, the hitting area of the dust cloth 3 can be effectively increased to improve the dust removal effect.

When the dust removal effect needs to be improved, the driving motor 10 stops running when the cleaning rod 2 pops outward;

The connecting ring 7 is driven to rotate by rotating the motor 19 to rotate the dust cloth 3. At this time, air is blown outwards through the cleaning rod 2, and the auxiliary plate 18 sucks air outwards, so that the air in the dust cloth 3 passing through the cleaning rod 2 and the auxiliary plate 18 flows from the inside to the outside, and the dust on the dust cloth 3 is efficiently blown off.

The above-mentioned specific embodiments are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific embodiments. Any low-noise pulse dust collector that complies with the claims of the present invention and any appropriate changes or modifications made thereto by ordinary technicians in the corresponding technical field shall fall within the patent protection scope of the present invention.
