[0021] When the filtering device is in use, the device body 1 is stably placed by the legs. After the corresponding pipelines are connected, the dust-laden gas enters the interior of the device body 1 through the air inlet 9. Under the guidance of the partition 2, the gas flows upward from the support rod 4. When passing through the bag 5, the bag 5 filters the gas, and the dust is intercepted outside the bag 5. The clean gas passes through the bag 5 and is discharged from the circular hole 7. Finally, the clean air is discharged to the outside from the air outlet 10, and the dust is discharged through the drop hopper 11. In this process, the sealing gasket 8 ensures the sealing of the connection between the bag 5 and the fixed plate 3, prevents the dust-laden gas from passing through the installation part of the bag 5, and ensures the filtering effect. When the bag 5 needs to be removed, the fixed structure 6 is operated. After the fixed structure 6 gives way, the bag 5 can be quickly removed. The structure is simple and the operation is convenient and quick.

[0022] Through the above implementation scheme, the fixed structure 6 includes a movable rod 601, a support plate 602, a tightening spring 603 and an operating component 604, the movable rod 601 is connected to the support plate 602, and the movable rod 601 is arranged on the support rod 4, the tightening spring 603 is sleeved on the movable rod 601, the operating component 604 is arranged at the lower end of the movable rod 601, the support rod 4 is provided with a through hole, the movable rod 601 passes through the through hole, the support plate 602 is abutted against the lower end of the cloth bag 5, the ends of the tightening spring 603 contact the support rod 4 and the support plate 602 respectively, the operating component 604 includes a threaded hole 6041, a round rod 6042 and a threaded joint 6043, the round rod 6042 is opened at the lower end of the movable rod 601, the round rod 6042 and the threaded joint The head 6043 is fixedly connected, and the threaded joint 6043 is threadedly connected in the threaded hole 6041, the round rod 6042 is symmetrically arranged on the movable rod 601, and a fixed structure 6 is arranged on the support rod 4 below the cloth bag 5. The clamping spring 603 is used to apply an elastic force to the support plate 602, and the support plate 602 has a clamping effect on the cloth bag 5, which can ensure that the cloth bag 5 has good stability after installation. At the same time, the operating component 604 can be used to quickly pull down the movable rod 601, so that the support plate 602 gives way and compresses the clamping spring 603, which is convenient for quickly removing the cloth bag 5, making the installation and disassembly of the cloth bag 5 extremely simple, and the operating component 604 is fixed to the lower end of the movable rod 601 by a threaded connection, and can be disassembled and replaced.

[0023] When installing the cloth bag 5, the round rod 6042 in the operating assembly 604 is used to pull down the movable rod 601, and the movable rod 601 brings the support plate 602 down and compresses the pressing spring 603, and then the upper end of the cloth bag 5 is inserted into the round hole 7, so that the upper end of the cloth bag 5 contacts the sealing pad 8, and then the round rod 6042 is released. Under the action of the pressing spring 603, the support plate 602 and the movable rod 601 rise until the support plate 602 abuts against the lower end of the cloth bag 5. At this time, under the effect of the pressing spring 603, the support plate 602 has a pressing effect on the cloth bag 5, which can ensure that the cloth bag 5 is in a stable state. The bag 5 has good stability after installation, and is used in conjunction with the sealing gasket 8 to ensure the sealing of the connection between the cloth bag 5 and the fixed plate 3. The cloth bag 5 can be used after installation. When the cloth bag 5 needs to be removed, the support plate 602 and other structures are pulled down again to make way, and then the cloth bag 5 can be removed. When necessary, after the cloth bag 5 is disassembled, the threaded joint 6043 at the end of the round rod 6042 can be unscrewed from the threaded hole 6041, and then the movable rod 601 and the support plate 602 are lifted, the fixed structure 6 is removed from the support rod 4, and then the tightening spring 603 can be replaced.
