Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to the air duct structure of a bag filter dust collector. Background Technology

[0002] Baghouse dust collectors are devices that can handle large air volumes, have good dust removal efficiency, and occupy a small area. They are widely used in industries such as power, metallurgy, building materials, and chemicals.

[0003] The existing Chinese patent with publication number CN215352554U discloses an air inlet duct for a bag filter. The existing technical solution has the following defects: Although the air passes through the filter screen to remove larger particles of impurities, and then passes through the holes in the flow channel, the air volume can be increased, decreased, or kept constant by selecting an appropriate inner diameter of the holes as needed, thereby adjusting the processing capacity of the bag filter, the above technical solution cannot automatically clean the dust and impurities remaining on the filter screen. After long-term use, dust and impurities adhere to the filter screen, which can easily cause blockage and thus affect its subsequent normal use. Utility Model Content

A rotating rod 7 is provided in the shaft seat, and one end of the rotating rod 7 passes through the filter screen 6. A fixing sleeve 4 is provided on the outer side of the rotating rod 7, and a first cleaning brush 2 is fixedly connected to the top and bottom surfaces of the fixing sleeve 4 on one side of the filter screen 6. A positioning bolt 3 passes through the top surface of the fixing sleeve 4 on one side of the first cleaning brush 2, and one end of the positioning bolt 3 extends into the interior of a positioning hole 5 opened on one side of the top surface of the rotating rod 7. A protective shell 14 is provided on one side of the lower top surface of the housing 1, and a motor 13 is fixedly installed in the protective shell 14. A synchronous pulley 9 is fixedly connected to the output end of the motor 13 and the rotating rod 7, and the two synchronous pulleys 9 are connected together. The system includes a synchronous belt 12 and a through-hole on the baffle plate 11, in which a baffle mesh 8 is fixedly installed. The housing 1 allows external air to be delivered into the baghouse dust collector for filtration. A filter screen 6 on one side of the housing 1 blocks dust and larger particles from entering the baghouse dust collector, effectively preventing the filter bags from being scratched by large particles and protecting the components. By opening the motor 13 in the protective housing 14, the motor drives the synchronous pulley 9 to rotate, which in turn drives the rotating rod 7 via the synchronous belt 12. This causes the first cleaning brush 2 on the fixed sleeve 4 of the rotating rod 7 to rotate, automatically cleaning the dust and impurities from the filter screen 6, preventing blockage and ensuring normal operation.

[0026] In one embodiment, a screw 16 is provided through one side of the top and bottom surfaces of the housing 1, and one end of the screw 16 extends into the interior of the threaded hole 15 opened on the insert block 17. The screw 16 is threadedly connected to the threaded hole 15, wherein the filter screen 6 can be fixed on the housing 1 by using the screw 16 and the threaded hole 15.

[0027] In one embodiment, the fixing sleeve 4 is sleeved on one end of the rotating rod 7, and the positioning bolt 3 is threadedly connected to the positioning hole 5. The fixing sleeve 4 can be fixed on the rotating rod 7 by using the positioning bolt 3 and the positioning hole 5.

[0028] In one embodiment, the wind deflector 8 and the wind deflector 11 are matched with the housing 1. The use of the wind deflector 11 and the wind deflector 8 can effectively alleviate wind pressure, reduce the wind pressure entering the bag filter, prevent excessive air pressure from damaging the bag filter, and protect the bag filter.

[0029] In one embodiment, the filter 6 is fitted to the housing 1.

[0030] In one embodiment, a second cleaning brush 10 is fixedly connected to one side of the windshield 8 on the rotating rod 7. The second cleaning brush 10 is matched with the windshield 8. When the rotating rod 7 rotates, it can drive the second cleaning brush 10 to rotate. When the second cleaning brush 10 rotates, it can automatically clean the dust adhering to the windshield 8, preventing dust from accumulating on the windshield 8, thereby ensuring its normal use in the future.

[0031] In one embodiment, a first cleaning brush 2 is matched with a filter screen 6, wherein dust and impurities on the filter screen 6 can be cleaned by using the first cleaning brush 2.

[0032] In one embodiment, a rubber ring is provided between the filter screen 6 and the housing 1.

[0033] In one embodiment, the control switch control circuit can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0034] Working principle:

[0035] In use, the outer casing 1 allows external air to be delivered into the baghouse dust collector, where the incoming gas is filtered. The filter screen 6 on one side of the casing 1 blocks dust and larger particles from entering the baghouse dust collector, effectively preventing the filter bags from being scratched by large particles and protecting the components inside. By opening the motor 13 inside the protective casing 14, the motor 13 drives the synchronous pulley 9 to rotate, which in turn drives the rotating rod 7 via the synchronous belt 12, causing the first cleaning sleeve 4 on the rotating rod 7 to rotate. When brush 2 rotates, it automatically cleans the dust and impurities on filter screen 6, preventing dust and impurities from adhering to filter screen 6 and causing blockage, thus ensuring its normal operation. The use of wind baffle 8 on wind baffle plate 11 can effectively alleviate wind pressure and reduce the wind pressure entering the bag dust collector, preventing damage to the bag dust collector due to excessive air pressure, thus protecting the bag dust collector. When rotating rod 7, it can drive the second cleaning brush 10 to rotate, and the second cleaning brush 10 can automatically clean the dust adhering to wind baffle 8 while rotating, preventing dust from accumulating on wind baffle 8, thus ensuring its normal operation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
