Description

Technical Field

[0001] This utility model relates to the technical field of bag filter dust collection equipment, and in particular to a bag filter dust collection equipment with a periodic bag cleaning mechanism. Background Technology

[0002] A bag filter is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt. It uses the filtration effect of fibrous fabric to filter dust-laden gas. When dust-laden gas enters the bag filter, 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 material, the dust is trapped, thus purifying the gas.

[0003] When air containing fine dust passes through a filter bag, the impurities and dust are intercepted by the filter bag. After long-term operation, when a lot of impurities and dust accumulate in the filter bag, it will affect the filtration effect of the filter bag. At this time, dust removal is often carried out by a dust removal mechanism. However, most current dust removal mechanisms use a vibrating motor to drive the filter bag to vibrate, thereby causing the dust to fall. However, relying solely on vibration to remove dust cannot clean up some of the dust. Utility Model Content

Multiple bag filter elements 10 are fixedly inserted through the filter element support 11, and the bottom ends of the multiple bag filter elements 10 are all fixedly inserted through the same stabilizing plate 6.

[0023] In this embodiment, the vibration mechanism includes a vibration bracket 13, a U-shaped metal block 14, a transmission assembly, a vibration housing 17, a drive assembly, and two auxiliary springs 18. The vibration bracket 13 is fixedly installed on the top of the conduction plate 12. The U-shaped metal block 14 is fixedly installed on the top of the vibration bracket 13. The transmission assembly is provided on the inner side of the U-shaped metal block 14. The vibration housing 17 is fixedly installed on the bottom of the transmission assembly. Auxiliary springs 18 are fixedly installed on both sides of the vibration housing 17. The other ends of the two auxiliary springs 18 are connected to the inner wall of the vibration bracket 13. The drive assembly is provided on the vibration housing 17.

[0024] In this embodiment, the transmission assembly includes a positioning post 15 and a connecting rod 16. The positioning post 15 is fixedly installed on the inner side of the U-shaped metal block 14. The connecting rod 16 is rotatably sleeved on the positioning post 15. The bottom end of the connecting rod 16 is connected to the vibrating shell 17, so that the vibrating shell 17 can be driven to swing through the connecting rod 16.

[0025] In this embodiment, the drive assembly includes two synchronous motors 20 and two eccentric blocks 19. Eccentric blocks 19 are rotatably mounted on both sides of the vibration housing 17. Two synchronous motors 20 are fixedly mounted on the inner side of the vibration housing 17. The output shafts of the two synchronous motors 20 are respectively connected to the corresponding eccentric blocks 19. The rotation of the synchronous motors drives the eccentric blocks to rotate.

[0026] In this embodiment, a control panel 4 is fixedly installed on one side of the support bracket 3. Both synchronous motors 20 are electrically connected to the same control panel 4, facilitating the control of the synchronous motors 20. The control method of the synchronous motors 20 mentioned in this embodiment is automatic control through the control panel 4. The control panel 4 is a PLC controller. The control circuit of the control panel 4 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. Therefore, the control method and circuit connection will not be explained in detail.

[0027] In this embodiment, the cleaning mechanism includes a cleaning ring 8 and multiple soft brush strips 9. The cleaning ring 8 is fixedly installed inside the cleaning hole, and multiple soft brush strips 9 are fixedly installed inside the cleaning ring 8 to facilitate cleaning of the bag filter element 10.

[0028] Working Principle: During use, the operator connects the relevant equipment to the air inlet and outlet of the dust collection chamber 1. The program is then set via the control panel 4, and the equipment automatically cleans at fixed time intervals. When the designated time is reached, the control panel 4 automatically starts two synchronous motors 20. The two synchronous motors 20 rotate in the same direction, driving the corresponding eccentric blocks 19 to rotate and generate inertia. The rotation of the two eccentric blocks 19 causes the same vibrating housing 17 to swing. The vibrating housing 17 swings via the connecting rod 16, which swings around the positioning post 15. Simultaneously, two auxiliary springs 18 assist... The vibrating housing 17 oscillates at a small amplitude but high frequency. The vibration of the vibrating housing 17 drives the vibration support 13 to vibrate, which in turn drives multiple bag filter elements 10 to vibrate through the transmission plate 12. When the bag filter element 10 vibrates, it comes into contact with the corresponding cleaning ring 8. When the multiple soft brush strips 9 set on the inner side of the cleaning ring 8 come into contact with the bag filter element 10, the soft bristles on them will enter the bag filter element 10 through the gaps, thereby clearing the gaps of the bag filter element 10 and loosening the impurities and dust on it, making it easier for the bag filter element 10 to vibrate and clean it. The cleaned dust falls with inertia and is discharged through the dust hopper 2.

[0029] The technological advancement of this invention compared to the prior art is as follows: the vibration mechanism drives the transmission plate 12 to vibrate, which in turn drives the bag filter element 10 to vibrate. When the bag filter element 10 vibrates, it will touch the soft brush strip 9 inside the cleaning ring 8. The soft brush strip 9 will loosen some stubborn dust on the bag filter element 10 and make it fall off, effectively improving the practicality of the equipment.
