[0002] Positive pressure dust collector is a dust filtering device, the main function of which is to separate fine, dry, non-fibrous dust from the air. Its working principle is usually that after the dust-laden gas enters, the dust with large particles and high specific gravity settles down due to the action of gravity, and then the discharge pipe is collected to the discharge port main pipe and bagged;

[0003] When using the existing positive pressure dust collector, a positive pressure pulse back-blowing bag device is usually used. The material discharge is composed of a star-angle closed valve and a spiral unloading machine. A large amount of dust is dispersed during unloading. At the same time, when the dust is bagged, the collection bags need to be loaded into the ash discharge pipe in turn. The process is relatively cumbersome, and it is laborious to replace the collection bags filled with dust. In addition, when the dust is bagged, it is easy for the dust to escape everywhere, affecting the surrounding environment, which will bring great safety hazards to the physical and mental health of the bagging personnel.

[0031] It should be noted that the utility model is a positive pressure dust collector that is convenient for bagging. When in use, first, a positive pressure conveying pipe can be installed at the outlet of the external star-angle sealed valve as needed, and the positive pressure conveying pipe can be connected to the top of the compression bin 2. The dust in the positive pressure conveying pipe is conveyed to the compression bin 2 with the air. The spiral dust reduction component in the compression bin 2 performs dust reduction treatment on the conveyed dust. After that, the dust falls freely at the bottom of the compression bin 2 and is stored. A connecting pipe bin 3 is provided at the bottom of the compression bin 2. After the dust is collected, it can fall to the connecting pipe bin 3 to complete the dust removal process.

[0032] When dust needs to be discharged, the diverter cover plate 8 is connected to the dust discharge valve 9 through the bellows 10, the dust discharge valve 9 is connected to the dust discharge port of the annular discharge pipe 4, the top of the annular discharge pipe 4 is connected to the connecting pipe bin 3, and the top of the diverter cover plate 8 is connected to the end of the push rod of the electric telescopic rod 7, so that the two electric telescopic rods 7 can be started as needed, and the diverter cover plate 8 is driven to move upward by retracting the push rods of the two electric telescopic rods 7;

[0033] Afterwards, the dust collecting box 11 can be pushed into the card slot 17. Since a plurality of installation boxes 12 are arranged in the dust collecting box 11, and a plurality of installation boxes 12 are arranged with collection bags 13, and the position of the collection bags 13 matches the shunt pipe 16 at the shunt cover plate 8, after the dust collecting box 11 is moved to a suitable position, the push rod of the electric telescopic rod 7 can be controlled to extend again, driving the shunt cover plate 8 to move downward to cover the dust collecting box 11, and then the dust discharge valve 9 can be opened to discharge the dust collected at the connecting pipe bin 3 into the collection bag 13. During the discharge process, the collection bag 13 is not exposed to the outside, which can prevent the dust from escaping into the surrounding environment, and the plurality of collection bags 13 collect the dust at the same time, thereby improving the discharge efficiency;

[0034] At the same time, multiple dust collection boxes 11 can be prepared according to actual needs, and multiple collection bags 13 can be pre-installed in the installation box 12. After that, when one of the dust collection boxes 11 is full, the dust discharge valve 9 can be closed first, and the push rod of the electric telescopic rod 7 is retracted to drive the diversion cover 8 away, and then the full dust collection box 11 can be pulled out of the card slot 17. After that, a new dust collection box 11 can be pushed into the card slot 17 and replaced according to the above steps. The replacement is relatively quick and does not require personnel to directly replace it under the dust discharge valve 9. After all the collection is completed, the collection bag 13 can be sealed according to the existing steps, and the collection bag 13 can be taken and placed;
