The fixing ring 5 and the limiting groove 6 ensure the connection strength between the filter bag 2 and the support frame 1, and ensure that the filter bag 2 is evenly expanded and contracted, avoiding a large amount of accumulation of the filter bag 2 structure in a certain place, which is conducive to the use of dust removal telescopic cloth bags.
[0026] Furthermore, the telescopic rod 102 includes a bottom rod 1021 , a moving block 1022 is provided inside the bottom rod 1021 , a top rod 1023 is fixedly connected to the top of the moving block 1022 , the diameter of the top rod 1023 is smaller than the diameter of the moving block 1022 , and the top rod 1023 passes through the bottom rod 1021 .
[0027] Furthermore, a connecting ring 7 is fixedly connected to the top of the uppermost support ring 101 , and a fixing plate 9 is connected to the top of the connecting ring 7 via connecting bolts 8 .
[0028] It is worth noting that an air outlet pipe 10 runs through the fixing plate 9 , and a pipe joint 11 is connected to the top of the air outlet pipe 10 . The air outlet pipe 10 is used to discharge filtered air and can also be used as a pulse air pipe.
[0029] It is worth noting that corresponding through holes 12 are provided on the fixing plate 9 and the connecting ring 7 , and the screw rod of the connecting bolt 8 passes through the through hole 12 and is connected with a nut 13 .
