[0004] However, the dust collector filter bag is usually a whole. After the compressed air is blown, a large amount of dust is still retained in the lower part of the filter bag. It is easy to get clogged after long-term accumulation. After clogging, the whole bag needs to be disassembled and replaced, which is cumbersome and inconvenient. In view of this, we propose a segmented filter bag for dust collector. Utility Model Content

[0028] In this embodiment, by rotating the corresponding chuck 28, the block 29 slides along the corresponding limit groove 27, and the block 29 is pulled out from the groove 26, and then the chuck 28 is removed from the mounting hole 25, and the insertion rod 84 slides on the inner wall of the insertion hole 74, so that the bag cage 2 81 falls off and moves away from the bag cage 1 71, and then the bag cage 2 81 is taken out from the mounting hole 25, which is convenient for quick disassembly of a single bag cage 2 81. Example

[0029] See also Figure 1-7 On the basis of the first embodiment, the utility model provides a technical solution: preferably, a filtering mechanism 7 is arranged on the external threaded sleeve 6, and the filtering mechanism 7 includes a bag cage 1 71, and the top of the bag cage 1 71 is connected to a dust port 72, and the inner wall of the dust port 72 is threadedly connected to the external threaded sleeve 6, and the bottom end of the bag cage 1 71 is provided with a collar 1 73, and the collar 1 73 is surrounded by a plug hole 74, and the bottom end of the bag cage 1 71 is provided with an annular groove 75, and the filtering mechanism 7 is provided with a segmentation mechanism 8, and the segmentation mechanism 8 includes a bag cage 2 81, and the inner wall of the bottom end of the bag cage 2 81 is connected to a blocking platform 82, and the blocking platform 82 is a solid structure , used to block the lower end of the bag cage 81, the top of the bag cage 81 is sleeved with a ring 83, and the ring 83 is connected with a plug rod 84, and the plug rod 84 is plugged into the socket 74. The top of the bag cage 81 is connected with a ring edge 85, and the ring edge 85 is plugged into the inner wall of the ring groove 75. The number of mounting holes 25, chucks 28, dust inlet pipes 4, through holes, external threaded sleeves 6, filtering mechanisms 7 and segmented mechanisms 8 is the same. The bottom end of the bag cage 81 in each segmented mechanism 8 is respectively abutted against each chuck 28, and the outer walls of each bag cage 1 71 and bag cage 2 81 are sleeved with filter cloth 9, and one side of the box body 1 is connected with an air outlet pipe 10.

[0030] In this embodiment, by adjusting the inner rod of the hydraulic rod 23 to contract, the bottom cover 24 is driven away from the bottom of the box body 1, so that each bag cage 2 81 follows the bottom cover 24 to descend, and then separates from each bag cage 1 71, so that all bag cages 2 81 can be conveniently replaced and dust cleaned in a centralized manner. Rotating the bag cage 1 71 can separate it from the corresponding external threaded sleeve 6, thereby completing the disassembly of the bag cage 1 71.

[0031] Working principle: the dust inlet pipe 4 is used to connect the dust pipe to discharge the dust into the box body 1, enter the bag cage 1 71 and the bag cage 2 81 through the top plate 5, and filter through the filter cloth 9. The filtered air is discharged from the exhaust pipe 10. The bag cage 1 71 and the bag cage 2 81 are connected, so the dust will be concentrated in the bag cage 2 81 for deposition. When there is full of dust in a single bag cage 2 81, the corresponding chuck 28 can be rotated from the bottom of the box body 1 to make the card block 29 slide along the corresponding limit groove 27 and align with the card groove 26, so as to extract the card block 29 from the card groove 26, and then remove the chuck 28 from the mounting hole 25. At this time, the bottom of the corresponding bag cage 2 81 loses the limit resistance, and the card block 29 can be removed from the mounting hole 25 by inserting the card block 29. The rod 84 slides on the inner wall of the insertion hole 74, so that the bag cage 81 falls off and moves away from the bag cage 1 71, and then the bag cage 81 is taken out from the mounting hole 25, which is convenient for quick disassembly of a single bag cage 81, without opening the box body 1 as a whole and avoiding the cumbersome process of threaded disassembly. After cleaning the dust in the bag cage 81, replace the new filter cloth 9, and reinsert the bag cage 81 from the mounting hole 25. The bag cage 81 slides vertically along the inner wall of the mounting hole 25 and is vertically aligned with the bag cage 1 71, so as to realize the quick plugging of the insertion rod 84 and the insertion hole 74, and then the chuck 28 is pushed into the mounting hole 25, the block 29 enters from the slot 26, and the chuck 28 is rotated again to cause the block 29 to enter the limit slot 27 In the process, the installation of the chuck 28 is realized, and the chuck 28 is made to resist the bottom end of the bag cage 21 to ensure the stability of the installation. The above method can be used to efficiently install and disassemble the bag cage 21 that needs to be replaced, and the convenience of installation and disassembly is improved, and the problem of blockage caused by long-term accumulation of dust is avoided. On the other hand, the inner rod of the hydraulic rod 23 can be adjusted to shrink, thereby driving the bottom cover 24 away from the bottom of the box body 1. The bottom of the box body 1 is opened. At this time, the bottom of all the bag cages 21 loses resistance, so that each bag cage 21 is limited in the installation hole 25 where it is located and follows the bottom cover 24 to descend, and then detaches from each bag cage 1 71, which is convenient for all bag cages 21 to be centralized. Replacement and dust cleaning, rotating the bag cage 1 71 can make it detach from the corresponding external threaded sleeve 6, thereby completing the disassembly of the bag cage 1 71, facilitating maintenance and cleaning and replacement of the filter cloth 9. Conversely, each bag cage 1 71 is re-threadedly connected to the corresponding external threaded sleeve 6 through the dust port 72, and each bag cage 2 81 is placed in the corresponding mounting hole 25. It will not fall off due to the drag of each chuck 28. The inner rod of the hydraulic rod 23 is adjusted to extend, and the bottom cover 24 is pushed to drive the bag cage 2 81 to rise and dock with each bag cage 1 71 to complete unified installation and improve installation efficiency. The blocking platform 82 is a solid structure, which is used to block the lower end of the bag cage 2 81 to prevent dust from overflowing and leaking from the bottom of the bag cage 2 81.
