Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to an anti-clogging bag filter. 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, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the bag filter, larger and heavier 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] In Chinese patent application number 202421513250.0, this utility model discloses an anti-clogging bag filter. The bottom end of the air guiding component is connected to several dispersing components, each of which is inserted into a corresponding dust bag. The dispersing component includes a hollow tube frame connected to the air guiding component. The hollow tube frame is inserted into the dust bag. The bottom end of the hollow tube frame has a first through hole, and several second through holes are equally spaced along the length of the hollow tube frame. This device, by setting the hollow tube frame, the first through hole, the second through hole, etc., cleans the dust bag by backflushing, preventing the dust bag from clogging.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: The above-mentioned device achieves dust removal operation on the dust collection bag by back-blowing, and then the electric telescopic rod, together with the mounting plate and the ball, impacts the first fixed plate to assist in dust removal. However, the first fixed plate is fixedly installed inside the shell, and the vibration generated by the impact has a limited transmission range and a small amplitude, which is difficult to act on the entire dust collection bag, and may lead to incomplete dust removal. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology removes dust from the dust collector bag by back-blowing the dust collector bag and causing it to vibrate by impacting the first fixed plate. However, the range of vibration transmission is limited and it is difficult to act on the entire dust collector bag, which may lead to incomplete dust removal. Therefore, we propose an anti-clogging bag dust collector.

[0006] To achieve the above objectives, this application adopts the following technical solution: an anti-clogging bag filter, comprising: a dust removal assembly, an anti-clogging component installed on the dust removal assembly, the dust removal assembly including a shell, an air inlet pipe installed at the lower end of the shell, a drain pipe installed on the bottom surface of the shell, an installation ring fixedly connected to the inner wall of the shell, a dust removal frame provided on the upper surface of the installation ring, a cage frame installed on the bottom surface of the dust removal frame, a dust removal bag body installed on the cage frame, the anti-clogging component including a cover, the cover installed at the upper end of the shell, an air supply pipe and an exhaust pipe installed on the cover, a cylinder installed on the upper surface of the cover, the output end of the cylinder extending through the cover into its inner cavity, an air supply frame fixedly connected to the output end of the cylinder, a connecting pipe installed at the lower end of the air supply frame, a blowing frame installed at the output end of the connecting pipe, a rotating frame fixedly connected to the upper surface of the blowing frame, a rotating frame rotatably connected to the rotating frame, the rotating frame corresponding to the cage frame.

[0007] Preferably, the lower end of the shell is configured as a funnel shape, and the drain pipe is connected to the inner cavity of the shell; It is used to conveniently discharge the dust cleaned from the dust bag body into the housing, ensuring the cleanliness of the inside of the housing.

[0008] Preferably, the housing and the cover, as well as the mounting ring and the dust collector are all installed together by bolts and nuts, and a sealing ring is provided between the housing and the cover; It is designed to facilitate the disassembly of the cover and dust removal rack, reducing the difficulty of later maintenance, and the sealing ring further enhances the overall sealing performance of the device.

[0009] Preferably, the dust collector frame has holes that communicate with the cage frame, the cage frame has multiple sets of exhaust holes, and the exhaust frame is equipped with multiple sets of exhaust hoods, with the exhaust holes and exhaust hoods corresponding to each other. This is used to facilitate the delivery of backflushing gas from the gas conveying frame to the cage frame, and to clean the dust collector bag body by backflushing, preventing the dust collector bag body from becoming clogged and affecting subsequent dust removal operations.

[0010] Preferably, the inner diameter of the cage is larger than the diameter of the air blowing frame, one end of the connecting pipe is connected to the air supply frame, and the other end of the connecting pipe is connected to the air blowing frame; This allows the air blower to move vertically inside the cage, facilitating subsequent cleaning operations.

[0011] Preferably, a connector is provided at one end of the gas supply pipe, and a hose is connected to the gas supply pipe through the connector. The input end of the gas supply frame is connected to the hose. This is used to ensure that the air supply pipe can continue to deliver backflushing gas into the air supply frame while it is moving up and down, thus ensuring the smooth progress of the backflushing operation.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, when cleaning the dust bag body is required, the air supply pipe and the external air supply pipe are connected together while the cylinder is activated. The external air used for backflushing passes through the air supply pipe, the air supply frame, and the connecting pipe in sequence, and is finally discharged from the air blowing frame and then enters the cage. Finally, this air acts on the dust bag body to backflush it. Under the action of the cylinder, the air blowing frame will make a reciprocating linear motion. During the movement, the rotating frame contacts the inner wall of the cage. During the contact, the rotating frame will rotate and generate vibration. The vibration is transmitted to the dust bag body through the cage, further increasing the cleaning effect of the entire device. Attached Figure Description

A cover 21 is installed on the upper end of the housing 11. An air supply pipe 22 and an exhaust pipe 23 are installed on the cover 21. A cylinder 24 is installed on the upper surface of the cover 21. The output end of the cylinder 24 extends through the cover 21 into its inner cavity. An air supply frame 25 is fixedly connected to the output end of the cylinder 24. A connecting pipe 26 is installed at the lower end of the air supply frame 25.

A rotating frame 29 is rotatably connected to the rotating frame 28. The rotating frame 29 corresponds to the cage frame 16.

[0017] After moving the housing 11 to the designated position and fixing it, the cage frame 16 is installed onto the dust collector frame 15, followed by the dust collector bag body 17. The connections of each component are then inspected. After inspection, the dust collector frame 15 is installed onto the mounting ring 14 using bolts and nuts. The air supply pipe 22 and the air supply frame 25 are then connected together. Finally, the housing 11 and the cover 21 are assembled together using bolts and nuts. Because flanges are installed on the inlet pipe 12, drain pipe 13, air supply pipe 22, and exhaust pipe 23, operators can connect them to the corresponding pipes. During actual operation, the gas to be processed enters the housing 11 through the inlet pipe 12, and then the dust collector bag body 17 performs dust removal on this gas. The purified gas is discharged from the exhaust pipe 23. When it is necessary to clean the dust collector bag body 17... During the cleaning process, the air used for backflushing is delivered from the air supply pipe 22 to the air supply frame 25, and then through the connecting pipe 26 to the air blowing frame 27. Finally, the pressurized air is discharged from the air blowing frame 27. This air is discharged from the cage frame 16 and directly acts on the dust collection bag body 17 to perform backflushing treatment on the dust collection bag body 17. Under the action of the cylinder 24, the air supply frame 25 will continuously perform up and down linear reciprocating motion. During the movement, the rotating frame 29 will rotate under the action of the cage frame 16, causing the cage frame 16 to vibrate, further increasing the cleaning effect of the entire device. The rotating frame 29 is made of elastic material and has a certain deformation capacity. The cleaned dust is finally discharged from the shell 11 through the drain pipe 13. Before use, some sensors and instruments for monitoring will be installed on the device so that the operator can monitor the actual situation of the entire device in real time.
