Background
In the metallurgical and foundry industry, production processes such as smelting, casting, grinding, cutting, etc., release significant amounts of metal dust, oxide particles, and other hazardous materials.

To address this challenge, bag house dust collectors effectively capture and remove particulate matter from these dust-laden gases by filtering them, ensuring that the exhaust gases emitted to the atmosphere meet environmental standards.
Conventional bag-type dust collectors typically remove dust by blowing compressed air from top to bottom. The method comprises the step of impacting the outer surface or the inner part of the cloth bag through high-pressure airflow to promote the attached dust to fall off.

After dust-containing gas filters through the sack 107, the dust falls down into the dust fall hopper 102, get into the dust discharge pipe 103 downwards through the dust fall hopper 102 again, after the motor 702 is started, the motor 702 output shaft drives the flower type piece 703 and rotates, flower type piece 703 can be continuously with the dust down conveying of collecting, can prevent effectively again that the inside gas of frame 101 from being discharged through the dust discharge pipe 103, when the dust needs to be discharged, open the dust discharge pipe 103 valve, can discharge the dust and collect, the design of flower type piece 703 can be continuous carry the dust of collecting, avoid the inside gas of frame 101 to discharge through the dust discharge pipe 103 simultaneously, in flower type piece 703 rotation, the protruding 708 of disc 707 and beat the contact of pole 705 are driven in step, through the rotatory repeated propelling movement of pole 705 back and forth of disc 707, buffer spring 706 provides the restoring force, make beat pole 705 can reset rapidly after beating, beat pole 705 on the support cylinder 701, the produced is passed through support cylinder 701 and is discharged the dust of collecting, thereby guarantee that the dust can take place stably to close the dust in the long-term operation system, can be guaranteed, the dust can be stably closed in the dust can be guaranteed to the operation system is guaranteed after the dust is discharged through the support cylinder 701.
As shown in fig. 14, the dust collector further comprises a rotating shaft 801, bevel gears 802, a beating plate 803, a rotating block 804 and a hinging rod 805, wherein each face of the outer side wall of the dust collector 102 is rotationally connected with the rotating shaft 801, the beating plate 803 is connected to the rotating shaft 801, dust can be prevented from adhering to the outer wall of the dust collector 102 by continuously beating the beating plate 803, bevel gears 802 are welded at two ends of the rotating shaft 801, two adjacent bevel gears 802 are meshed with each other, the lower end of the foremost beating plate 803 is rotationally connected with the rotating block 804, the hinging rod 805 is rotationally connected to the rotating block 804, and the lower end of the hinging rod 805 is rotationally connected with the upper end of the rotating rod 704.
In the continuous rotation process of the rotating block 804, the hinging rod 805 is driven to rotate, the hinging rod 805 drives the rotating block 804 to rotate, and pulls the front-most flapping plate 803 to rotate, a synchronous transmission chain is formed by the cooperation of the rotating shaft 801 and the bevel gear 802, and then the rest rotating shafts 801 and the flapping plate 803 are driven to synchronously rotate, so that all the flapping plates 803 can swing at the same moment, when the rotating block 804 moves downwards, the hinging rod 805 pushes the lower end of the flapping plate 803 to rotate outwards, the inner end of the hinging rod 805 rotates inwards and knocks on the dust-falling hopper 102, when the rotating block 804 moves upwards, the hinging rod 805 pulls the lower end of the flapping plate 803 to rotate inwards, the outer end of the hinging rod 805 faces outwards and knocks on the dust-falling hopper 102 again, and the flapping plates 803 can effectively knock the outer wall of the dust-falling hopper 102 through the alternate inner and outer swinging to prevent dust from adhering on the inner wall and ensure that the dust uniformly falls into the dust-discharging pipe 103.
It should be understood that this example is only illustrative of the application and is not intended to limit the scope of the application. Furthermore, it should be understood that various changes and modifications can be made by one skilled in the art after reading the teachings of the present application, and such equivalents are intended to fall within the scope of the application as defined in the appended claims.
