Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, in particular to a pulse bag dust collector. Background Art

[0002] Bag dust collectors are widely used to capture fine, dry, non-fibrous dust. The basic working principle of pulse dust collectors is: high-pressure compressed gas is released at a certain frequency through a pulse solenoid valve to impact the inner wall of the cylindrical dust bag, and the dust adhering to the outer wall of the cylindrical dust bag is knocked off. However, since the pulse airflow blown out by the nozzle is located above the dust bag, the airflow force above the dust bag is larger and smaller below, resulting in incomplete dust removal by the dust bag.

[0003] In the prior art, there is a pulse bag dust collector with publication number: CN219333580U, which includes: a bag dust collector body; a cover plate, which is arranged on the top of the bag dust collector body; two mounting rods, which are respectively fixedly mounted on the inner walls on both sides of the bag dust collector body; a mounting plate, which is fixedly mounted below the bag dust collector body; two sliding rods, which are both fixedly mounted on the top of the mounting plate; a cleaning mechanism, which is arranged on the two mounting rods and is located in the bag dust collector body; a lifting mechanism, which is arranged on the mounting plate; and two disassembly mechanisms, which are respectively arranged on the two sliding rods.

[0004] When the above-mentioned equipment is in use, although it can scrape off the dust on the inner wall of the equipment, it cannot shake off the dust attached to the outer wall below the dust bag. Especially when the air pressure is insufficient or the dust bag is large in size, the dust bag may not completely remove dust. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3 As shown, the pulse bag dust collector of this embodiment includes a shell 1, a top cover 2, a support leg 3, an air inlet pipe 4, an air outlet pipe 5, an air delivery pipe 6, a nozzle 7, a dust bag 8 and a sewage pipe 9. A fixing frame 10 is fixedly installed below the inner cavity of the shell 1, and a double-axis motor 11 is installed on the fixing frame 10. A scraper 12 is fixedly installed at one end of the bottom output shaft of the double-axis motor 11 through a fixing rod, and a rotating plate 13 is fixedly installed at one end of the top output shaft of the double-axis motor 11. A plurality of protrusions 14 that can hit the dust bag 8 are fixedly arranged on the rotating plate 13. The double-axis motor 11 drives the scraper 12 to scrape the dust on the inner wall of the shell 1 on the one hand, and drives the protrusion 14 to rotate on the other hand, hitting the bottom of the dust bag 8, and shaking off the dust attached to the outer wall below the dust bag 8.

[0022] Furthermore, the shell 1 is a circular structure, and the dust bag 8 is arranged in several layers in the inner cavity of the shell 1, and each layer has several convex blocks 14 arranged at equal angles, and the bottom of each layer of convex blocks 14 is evenly corresponding to the dust bag 8. It is ensured that the bottom of each dust bag 8 can be hit.

[0023] Furthermore, the top of the protrusion 14 is an arc-shaped structure.

[0024] Furthermore, the bottom of the shell 1 is a funnel structure.

[0025] Working principle: When it is necessary to clean the dust bag 8 and the bottom of the inner wall of the shell 1, the pulse airflow entering from the air pipe 6 passes through the nozzle 7 to the inside of the dust bag 8. The dust bag 8 vibrates under the action of the pulse airflow, and the dust attached to the upper part of the outer wall of the dust bag 8 is shaken off. When the dual-axis motor 11 rotates, on the one hand, the rotating plate 13 drives the protrusion 14 to rotate. During the rotation process, the protrusion 14 continuously hits the bottom of the dust bag 8, increases the vibration of the bottom of the dust bag 8, and shakes off the dust attached to the lower part of the outer wall of the dust bag 8. The shaken dust falls to the bottom of the inner cavity of the shell 1. On the other hand, it drives the scraper 12 to rotate, and the scraper 12 can scrape off the dust at the bottom of the inner cavity of the shell 1 and gather it into the sewage pipe 9.
