Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and particularly relates to a bag dust collector which is easy to maintain. Background Art

[0002] Bag filter, also known as bag dust collector, is a device used for dust filtration, mainly used to capture fine, dry, non-fibrous dust. Its working principle is to use the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper; while the gas containing finer dust is retained when passing through the filter material, so that the gas is purified. Bag filter is widely used in environmental protection equipment in mining, cement, building materials, grain and other projects. It has high dust removal efficiency, generally reaching more than 99.9%, and low dust removal concentration, which can be much lower than 30mg / m 3 In addition, bag dust collectors also play an important role in industrial production, environmental protection, medical care, transportation and other fields.

[0003] Publication number "CN210964325U" is a bag dust collector that is easy to maintain, including a base, a base frame is fixedly installed on the top of the base, a body is fixedly sleeved inside the top of the base frame, the top of the body is located above the base frame, and a cross plate is fixedly installed inside the body. This bag dust collector that is easy to maintain is provided with a supporting shell and a through-port. Due to the design of the supporting shell, the supporting area of ​​the filter cloth is increased, so that the supporting effect of the filter cloth is improved. At the same time, due to the uniform design of the through-port, dust-containing gas or high-pressure pulse gas can pass smoothly. Compared with the traditional vertical pole frame, the through-port limits the flow area of ​​the airflow, thereby increasing the flow rate of the high-pressure pulse gas and increasing the disturbance effect on the filter cloth, so that the dust removal effect of the filter cloth is improved, thereby increasing the practicality of the bag dust collector.

[0004] Although the above-mentioned new type increases the flow rate of high-pressure pulse gas and increases the disturbance effect on the filter cloth, so that the dust removal effect of the filter cloth is improved, thereby increasing the practicality of the bag filter, the filter cloth is fixed by threaded connection, and the threaded connection requires precise alignment and rotation operations, and the installation process is relatively cumbersome, especially in the case of limited space or poor operating environment, the installation difficulty will be further increased. Similarly, it also takes a lot of time and effort to disassemble, which reduces the efficiency of maintenance work. In addition, during the threaded connection process, if the operation is improper or too much force is used, the mouth of the filter bag may be damaged, resulting in failure of the filter bag or premature replacement, which increases maintenance costs. Utility Model Content

When it is necessary to clean the dust attached to the surface of the filter bag 13, the pulse valve 21 is opened, and then the high-pressure gas is introduced through the air guide pipe 20. After that, the high-pressure gas will be ejected from the jet port 23 through the ventilation cavity and the vertical pipe 22 in sequence, thereby causing the outer surface of the filter bag 13 to shake, so that the dust attached to the outer surface falls into the bottom end of the dust collector body 4. When it is necessary to replace the filter bag 13, the pressing blocks 163 on both sides of the connecting plate 12 are pressed, and the moving plate 162 drives the clamping block 164 to move. The clamping block 164 is retracted into the accommodating cavity 15 through the through groove 17, and the clamping block 164 is connected with the clamping groove 19. Then the filter bag 13 is pulled out downward, so that the fixing block 14 is connected with the fixing groove 18, and the removal of the filter bag 13 is completed.
