Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a bag-type low-pressure dust collector. Background Technique

[0002] A bag filter is a dry dust filtering device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag filter, dust particles with large particle size and high specific gravity settle down due to the action of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained and the gas is purified.

[0003] According to a bag filter with the Chinese patent publication number CN218687366U, which relates to the technical field of dust collectors, including a dust removal box body, one side of the inner wall of the dust removal box body is fixedly installed with a dust baffle, the outer walls of the dust removal box body and the dust baffle are both fixedly installed with sliding plates, and a filter plate is movably embedded between the inner surfaces of the two sliding plates. A plurality of first holes are opened at the top of the filter plate, and threaded pipes are fixedly communicated with the bottoms of the plurality of first holes. The outer surfaces of the plurality of threaded pipes are rotatably connected with a bag body. One side of the outer wall of the dust removal box body is fixedly installed with a support plate, aiming to solve the problem that when the bag filter in the above patent is used, since the equipment is integrally designed, after a long time, the dust particles gradually fill the gaps on the bag, and due to the difficulty of disassembling the equipment itself, it is difficult for the staff to clean and replace the bag inside it. A bag filter is proposed.

[0004] Although the above patent can conveniently disassemble and install the bag, the dust removal mechanism of some bag filters is fixedly installed, and the air inlet is arranged on one side. The dust on the surface of the bag near the air inlet is relatively more, while the dust on the surface of the bag far from the air inlet is relatively less. After a long time of operation, the dust on the bag near the air inlet is more, and it needs to be cleaned, resulting in low work efficiency. Summary of the Utility Model

[0022] The following further describes the present invention in detail with reference to the accompanying drawings.

[0023] Embodiment:

[0024] Refer to Figures 1-5, a bag - type low - pressure dust collector disclosed by the utility model includes a dust collector housing 1, an intake pipe 2 and an outlet pipe 3 which are connected and arranged on the side wall of the dust collector housing 1. A discharge pipe 5 is arranged at the lower end of the dust collector housing 1. A motor 4 is fixedly installed at the upper end of the dust collector housing 1. A connection panel 6 is fixedly installed at the output end of the motor 4. A number of filter bags 7 are arranged on the connection panel 6. The number of filter bags 7 is circumferentially arranged on the outer side of the periphery of the connection panel 6. A cleaning assembly 8 for cleaning the dust on the surface of each filter bag 7 is arranged on each of the number of filter bags 7. The filter bags 7 are circumferentially arranged around the connection panel 6, and the filter bags 7 can evenly filter the air with dust.

[0025] The cleaning assembly 8 includes a reciprocating threaded rod 82 rotatably arranged on the connection panel 6 and a threaded panel 81 threaded on the reciprocating threaded rod 82. The threaded panel 81 is slidably arranged on the corresponding filter bag 7. A slide bar 83 is fixedly installed on the lower end wall of the connection panel 6, and the threaded panel 81 is slidably arranged on the slide bar 83.

[0026] A connection groove 84 is formed on the connection panel 6. The reciprocating threaded rod 82 is rotatably arranged in the connection groove 84. A first gear 85 is fixedly installed on the reciprocating threaded rod 82. A number of first tooth blocks 86 are evenly arranged on the inner cavity side wall of the dust collector housing 1. The first tooth blocks 86 are meshed with the first gear 85. Through the arrangement of the reciprocating threaded rod 82, the threaded panel 81 can perform a reciprocating motion.

[0027] A number of cleaning brushes 803 are arranged at one end of the threaded panel 81 in contact with the filter bag 7. Through the arrangement of the cleaning brushes 803, the surface of the filter bag 7 can be cleaned.

[0028] First, the air to be filtered enters the inner cavity of the dust collector housing 1 from the intake pipe 2. Subsequently, the motor 4 is turned on. The motor 4 drives the connection panel 6 to rotate through its output end, and the connection panel 6 drives a plurality of filter bags 7 to rotate together. During the rotation of the filter bags 7, they all pass by the side of the intake pipe 2, and the air with dust passes through the corresponding filter bags 7, enabling each filter bag 7 to come into contact with the air, and thus filtering the air with dust well. During this process, the connection panel 6 drives the corresponding first gear 85 to rotate. During the movement of the first gear 85, the first gear 85 contacts the first tooth block 86 on the inner cavity side wall of the dust collector housing 1, causing the first gear 85 to rotate. The first gear 85 drives the reciprocating threaded rod 82 to rotate, and the reciprocating threaded rod 82 drives the threaded panel 81 to displace. The threaded panel 81 slides along the surface of the sliding rod 83 and the filter bag 7. During the sliding process, it cleans the surface of the filter bag 7 through its own cleaning brush 803. Due to the setting of the track of the reciprocating threaded rod 82, the threaded panel 81 can perform reciprocating motion along the reciprocating threaded rod 82, that is, it can achieve the effect of the threaded panel 81 reciprocatingly moving on the surface of the filter bag 7, and thus can conveniently clean the surface of the filter bag 7.

[0029] Refer to Figures 3-5 , the lower end of the reciprocating threaded rod 82 is rotatably provided with an inclined L-shaped rod 87, and the inclined L-shaped rod 87 contacts the lower end wall of the dust collector housing 1.

[0030] A rotating rod 802 is rotatably provided on the discharge pipe 5, a screw conveyor 801 is fixedly installed on the rotating rod 802, a second gear 89 is fixedly installed at the upper end of the screw conveyor 801, and a second tooth block 88 is fixedly installed on the side wall of the inclined L-shaped rod 87. The second tooth block 88 is meshed and connected with the second gear 89.

[0031] During the rotation of the reciprocating threaded rod 82, it will drive the inclined L-shaped rod 87 to move along the lower end wall of the dust collector housing 1. During the movement, it will clean the dust on the lower end wall of the dust collector housing 1. At the same time, the inclined L-shaped rod 87 drives the second gear 89 to rotate through the second tooth block 88, and the second gear 89 drives the screw conveyor 801 to rotate. The rotation of the screw conveyor 801 can drive the dust to move better and prevent the discharge pipe 5 from being blocked. The operation is simple and the use is convenient.

[0032] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
