Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, and in particular, to a dual-frequency vibrating bag filter dust collector. Background Technology
[0002] A baghouse dust collector is a dry filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter bags, the dust is trapped, thus purifying the gas.
[0003] After a period of use, the dust collection bags inside a baghouse dust collector accumulate a large amount of dust on their surface, affecting the dust collection efficiency. Therefore, regular dust removal is necessary. Current methods typically employ mechanical vibration to clean the bags by moving them up and down or left and right. This method is ineffective, and the bags easily become clogged again after a short time. Utility Model Content
[0004] Therefore, it is necessary to provide a dual-frequency vibrating bag filter with good dust removal effect.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-frequency vibrating bag dust collector, which includes a dust collector box with a cavity, filter bags, a dust removal assembly, and a vibrating assembly disposed on the dust collector box. Multiple filter bags are included. The dust removal assembly includes a dust removal pipe disposed on the side wall of the dust collector box, a main dust removal pipe connected to the dust removal pipe, and multiple branch dust removal pipes connected to the main dust removal pipe. Multiple air outlets are provided on the branch dust removal pipes. The vibrating assembly includes a guide strip disposed on the inner wall of the cavity, a rack slidable relative to the guide strip, a gear meshing with the rack, a rotating rod rotatably disposed on one side of the filter bag, and multiple vibrating rods disposed on the rotating rod. The gear is fixedly sleeved on the outside of the rotating rod, and the vibrating rods are used to strike the filter bags.
[0006] Furthermore, a fixing plate is provided inside the dust collection box. The fixing plate is located inside the cavity. The guide strip, the rack, the gear, and the rotating rod are all provided on the fixing plate. One end of the filter bag is connected to the fixing plate, and a through hole communicating with the filter bag is provided on the fixing plate. One end of the dust removal branch pipe extends into the filter bag through the through hole.
[0007] Furthermore, there are multiple gears and rotating rods, with one filter bag located between two adjacent rotating rods. The number of gears is the same as the number of rotating rods, and one gear corresponds to one rotating rod.
[0008] Furthermore, the diameter of the dust removal branch pipe is smaller than the diameter of the filter bag.
[0009] Furthermore, a bearing is provided between the rotating rod and the fixed plate, the outer ring of the bearing is fixedly connected to the fixed plate, and the inner ring of the bearing is fixedly connected to the rotating rod.
[0010] Furthermore, the vibrating rod is made of rubber material.
[0011] Furthermore, the rapping assembly also includes a driving component, which is disposed on the side wall of the dust collection box, and the piston rod of the driving component is connected to the rack.

[0027] The rapping assembly 4 includes a drive component 41, a guide bar 42, a rack 43, a gear 44, a rotating rod 45, and rapping rods 46. The drive component 41 is mounted on the side wall of the dust collection box 1. The guide bar 42, rack 43, gear 44, and rotating rod 45 are all mounted on the fixed plate 11. The guide bar 42 is fixedly mounted on the inner wall of the cavity 10. The rack 43 is slidable relative to the guide bar 42. The piston rod of the drive component 41 is connected to the rack 43. The drive component 41 drives the rack 43 to slide along the length of the guide bar 42. The gear 44 meshes with the rack 43. The rotating rod 45 is rotatably mounted on one side of the filter bag 2, and one end of the rotating rod 45 passes through the fixed plate 11. The gear 44 is fixedly sleeved on the outside of the rotating rod 45. There are multiple rapping rods 46, and multiple rapping rods 46 are mounted on the rotating rod 45. The rapping rods 46 are used to tap the filter bag 2, thereby filtering dust from the filter bag 2.
[0028] Furthermore, there are multiple gears 44 and rotating rods 45. One filter bag 2 is located between two adjacent rotating rods 45. The number of gears 44 is the same as the number of rotating rods 45, with one gear 44 corresponding to one rotating rod 45.
[0029] When in use, the drive unit 41 is activated, which drives the rack 43 to move, causing multiple gears 44 to rotate synchronously, thereby driving the rotating rod 45 and the vibrating rod 46 to rotate. In turn, the vibrating rod 46 strikes the filter bag 2, which can filter dust from the filter bag 2.
[0030] In this embodiment, the drive element 41 is a cylinder. In other embodiments not shown, the drive element 41 may also be an electric actuator.
[0031] To make the rotating rod 45 rotate more smoothly, a bearing (not shown in the figure) is provided between the rotating rod 45 and the fixed plate 11. The outer ring of the bearing is fixedly connected to the fixed plate 11, and the inner ring of the bearing is fixedly connected to the rotating rod 45.

[0033] Furthermore, an air inlet pipe 12 and an exhaust pipe 13 are also provided on the side wall of the dust collector 1. Both the air inlet pipe 12 and the exhaust pipe 13 are connected to the cavity 10, with the exhaust pipe 13 located above the air inlet pipe 12. Specifically, the air inlet pipe 12 is connected to the cavity 10 located below the partition 11, and the exhaust pipe 13 is connected to the cavity 10 located above the partition 11.

[0034] In use, the gas first enters the cleaning pipe 31, passes through the main cleaning pipe 32 and the branch cleaning pipe 33, and flows out from the air outlet before being sprayed onto the inner surface of the filter bag 2, thereby filtering the dust on the surface of the filter bag 2. Then, the drive unit 41 is activated, which drives the rack 43 to move, causing multiple gears 44 to rotate synchronously, thereby driving the rotating rod 45 and the vibrating rod 46 to rotate. In turn, the vibrating rod 46 strikes the filter bag 2, which can filter the dust from the filter bag 2 again.
[0035] The dual-frequency vibrating bag filter provided by this utility model sprays gas from the outlet 331 onto the inner surface of the filter bag 2, thereby filtering the dust on the surface of the filter bag 2. Then, the drive component 41 drives the rack 43 to move, so that multiple gears 44 rotate synchronously, thereby driving the rotating rod 45 and the vibrating rod 46 to rotate. In turn, the vibrating rod 46 beats the filter bag 2, which can filter the dust from the filter bag 2 again, thus achieving a good dust removal effect.
