Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, and more specifically, to an automatic ash discharging device for a pulse bag type dust collector. Background Technique

[0002] As is well known, with the continuous development of society, people's requirements for the surrounding environment are getting higher and higher. When dust removal is carried out on the surrounding environment, a pocket pulse bag type dust collector will be used. The pocket pulse bag type dust collector allows the dust-containing gas to enter through the air inlet. Larger dust directly falls into the ash hopper, and then the particulate dust in the gas is processed through the filter bag. The dust is retained on the outer surface of the filter bag, and then the purified gas is discharged through the operation of the fan.

[0003] In the existing publicly known technology, the application number is: CN202222634315.4, a pocket pulse bag type dust collector, which can shake off the dust on the surface of the filter bag without increasing the use cost. It includes a tank body. At the top inside the tank body, there is a mounting plate. Inside each through hole, there is a filter bag frame installed. Outside each filter bag frame, there is a filter bag installed. At the bottom end of the tank body, there is a dust discharge port, and a dust discharge device is arranged on the dust discharge port. At the top of the filter bag frame, there is a mounting ring. Inside the mounting ring, there is a connecting block. At the bottom end of the connecting block, there is a first connecting shaft. At the bottom end of the first connecting shaft, there is a spherical connection structure. At the bottom end of the spherical connection structure, there is a second connecting shaft. At the bottom end of the second connecting shaft, there is a bottom plate. At the top around the bottom plate, there are several support rods. At the top end of the support rods, there is a fixing ring. Outside the spherical connection structure, there is an outer sphere. Inside the outer sphere, there is an inner sphere, and the inner sphere can move at multiple angles inside the outer sphere.

[0004] However, the above patent still has certain drawbacks when in use: it drives the movement of the inner sphere through gas to achieve the dust removal operation of the filter bag, but it can only handle the dust on the surface of the filter bag, and the dust that falls to the bottom end of the dust collector cannot be effectively processed. As the operation time prolongs, the dust at the bottom is prone to adhere to the inner wall surface, thereby affecting the overall ash discharging quality, and the overall dust removal range and dust removal type are relatively limited, and it cannot perform a sufficient ash discharging and dust removal operation inside, restricting the use effect of the device.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

The collision balls 12 are provided to impact and remove the dust on the surface of the filter bag 10 through collision, improve the overall dust removal effect, and facilitate more thorough dust discharging operation in the subsequent process.

[0031] In one embodiment, a mounting plate 9 is fixedly installed at the top end position inside the pulse bag type dust collector main body 1. A plurality of groups of filter bags 10 are installed on the surface of the mounting plate 9 through filter bag brackets 10. The filter bags 10 are located between two adjacent connecting plates 7.

[0038] Working principle: During actual use, the dust-containing gas can be processed through the main body 1 of the pulse bag filter. As the operation time increases, a large amount of dust will adhere to the surface of the filter bag 10 and the ash discharge hopper 18 inside it. If it is not processed in time, it is likely to affect the subsequent dust removal effect, resulting in the unqualified quality of the discharged gas. When dust removal is required, the operation of the motor 23 can drive the drive shaft 24 to rotate. Then, the rotation of the drive shaft 24 can successively drive the brush 26 to continuously rotate on the inner wall of the fixed cylinder 27, the scraper 17 to continuously scrape on the surface of the ash discharge hopper 18, and the eccentric wheel 3 at the top to intermittently collide with the two moving plates 13 on both sides. When the collision occurs, it will drive the moving plate 13 to move outward. At this time, the collision ball 12 on the surface of the connecting plate 7 on the outer side will collide with the surface of the filter bag 10, realizing the first impact removal operation of the dust on its surface. After the eccentric wheel 3 moves past, the reset of the first spring 15 can drive the moving plate 13 to return to its original position. At this time, the collision ball 12 on the other side will perform a secondary impact on the surface of the filter bag 10, removing the dust again. Through the combined use of multiple groups of structures, the dust can be removed on a large scale, improving the overall dust removal effect, facilitating better use, and ensuring the cleanliness inside the device. The whole device has the advantages of good ash discharge effect, wide ash discharge area, and multiple types of ash discharge.
