Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, and more specifically to baghouse dust collectors. Background Technology
[0002] A baghouse dust collector 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, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.
[0003] After a period of use, dust and impurities tend to accumulate on the inner wall of a bag filter, requiring internal cleaning. Currently, most cleaning is done manually. However, manual cleaning requires workers to insert tools into the bag filter, which can easily cause dust to spill out. This spilled dust and impurities can harm the air quality and human health. Utility Model Content

A pulse valve is fixedly installed at the top of the dust collection cylinder, and a conduit is fixedly installed at the output end of the pulse valve. The end of the conduit away from the pulse valve is rotatably connected to the duct.
[0006] By adopting the above solution, the L-shaped branch pipe drives the cleaning brush to rotate and clean the impurities attached to the inner wall of the dust collector. The airflow blows air into the bag body through the connecting pipe, causing the dust and other impurities adsorbed on the outer surface of the bag body to fall off, eliminating the need for manual cleaning and preventing the overflow of dust and other impurities.

A suction pipe is fixedly installed on the top of the fan, and the top end of the suction pipe is fixedly connected to the dust collector. An exhaust pipe is fixedly installed at the bottom of the fan, and a filter screen is fixedly installed on the suction pipe. A filter plate is installed inside the filter screen.
[0008] By adopting the above scheme, the gas is filtered through the filter plate in the filter screen during the suction process, removing dust and other impurities and avoiding interference from dust and other impurities to the fan.
[0009] As a further improvement to this technical solution, multiple T-shaped rods are fixedly installed near the bottom of the air duct, and all of the multiple T-shaped rods are in contact with the bottom wall of the dust collector.
[0010] By adopting the above solution, multiple T-shaped rods are used to support the duct, thereby improving the stability of the duct during rotation.
[0011] As a further improvement to this technical solution, the gear assembly includes a first bevel gear and a second bevel gear. The first bevel gear is fixed to the output end of the motor, and the second bevel gear is fixedly disposed on the outer wall of the air duct. The first bevel gear and the second bevel gear are meshed together.
[0012] By adopting the above scheme, the second bevel gear drives the air duct to rotate, performing rotational adsorption and cleaning.
[0013] As a further improvement to this technical solution, a rotary joint is provided at the top of the duct, and the duct tube rotates with the duct through the rotary joint.
[0014] By adopting the above solution, the duct and the air duct are stably connected through a rotary joint.
[0015] As a further improvement to this technical solution, the L-shaped branch pipe has multiple air outlets on its side, which are used to spray air onto the surface of the cleaning brush.
[0016] By adopting the above method, air is blown out through multiple air outlets to clean the impurities attached to the surface of the cleaning brush.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This bag filter dust collector uses an L-shaped branch pipe to drive the connecting pipe and the bag body to rotate, which in turn causes the bag body to rotate and adsorb, improving the adsorption effect on dust and other impurities in the gas and making the removal of dust and other impurities in the gas more thorough.
[0019] 2. This baghouse dust collector features a cleaning mechanism that uses L-shaped branch pipes to rotate cleaning brushes and remove impurities adhering to the inner wall of the dust collection cylinder. Multiple air outlets blow air to remove impurities from the surface of the cleaning brushes. Simultaneously, airflow is directed through connecting pipes into the bag body, causing dust and other impurities adsorbed on the outer surface of the bag to fall off. This eliminates the need for manual cleaning, saving manpower and preventing dust and other impurities from overflowing, effectively protecting the air quality and human health.

[0031] The specific working principle of this utility model is as follows: The fan 31, in conjunction with the suction pipe 32, draws the gas to be cleaned into the dust collector 1 through the inlet pipe 2. The filter bag body 431 adsorbs dust and other impurities in the gas. The motor 44 then drives the first bevel gear 441 to rotate, which in turn drives the second bevel gear 442. The second bevel gear 442 then drives the air duct 41 to rotate, which in turn drives the L-shaped branch pipe 42. The L-shaped branch pipe 42 then drives the connecting pipe 43 and the filter bag body 431 to rotate, causing the filter bag body 431 to rotate and adsorb impurities, thus improving the adsorption effect on dust and other impurities in the gas and making the removal of dust and other impurities in the gas more thorough, effectively cleaning and removing dust.

The pulse valve 46 is activated to blow air through the pulse valve 46. The airflow is delivered to the air duct 41 through the duct 461, and then to the L-shaped branch pipe 42 through the air duct 41. It is then blown out through multiple air outlets 49 to clean the impurities attached to the surface of the cleaning brush 45. At the same time, the airflow blows into the bag body 431 through the connecting pipe 43, causing the dust and other impurities adsorbed on the outer surface of the bag body 431 to fall off. The cleaned dust and other impurities are discharged through the impurity removal port 5, which eliminates the need for manual cleaning, saves manpower, and prevents the overflow of dust and other impurities, effectively protecting the ambient air and human health.
