The closure disc 70 is a flange disc and is made of rubber. The closure disc 70 made of rubber can seal the inner ring of the lower supporting ring 20. The upper supporting ring 10 and the lower supporting ring 20 are both flange rings. Both of them are designed as flange rings, which helps the plurality of threaded rods 60 to be installed by penetrating. The top wall of the lower pipe body 21 and the upper pipe body 12 is coaxially provided with a ring groove 210. As shown, Figure 1 、 Figure 2 As shown, the two ends of the cartridge filter element 30 and the cartridge filter screen 40 are respectively inserted into the two ring grooves 210, and the cartridge filter screen 40 is sleeved on the cartridge filter element 30. The plurality of threaded rods 60 penetrates the closure disc 70, the lower supporting ring 20, the upper supporting ring 10 and the mounting plate 3 in sequence, and each threaded rod 60 is screwed with three nuts 61. The plurality of threaded rods 60 is circumferentially arranged on the periphery of the cartridge filter element 30. In this way, the filter cartridge is more stable as a whole. The three nuts 61 abut against the closure disc 70, the upper supporting ring 10 and the mounting plate 3, respectively.

[0043] The two ends of the cartridge filter element 30 and the cartridge filter screen 40 are respectively inserted into the two ring grooves 210, and the cartridge filter screen 40 is sleeved in the cartridge filter element 30, a plurality of threaded rods 60 pass through the closure disc 70, the lower support ring 20 and the upper support ring 10 in sequence, and two nuts 61 located on the same threaded rod 60 abut against the closure disc 70 and the upper support ring 10 respectively, and the closure disc 70 covers the inner ring of the lower support ring 20, so that the filter cartridge body assembly is completed, and further, the plurality of threaded rods 60 pass through the mounting plate 3 to be screwed with the nuts 61, the nuts 61 abut against the mounting plate 3, the vertical pipe 11 abuts against the mounting plate 3, the vertical pipe 11 communicates with the perforations 4, and the installation of the filter cartridge of the dry dust collector into the dry dust collector 1 is completed, and the preliminary assembly of the filter cartridge body can be quickly completed by inserting the two ends of the cartridge filter element 30 and the cartridge filter screen 40 into the ring grooves 210 respectively and sleeving the cartridge filter screen 40 in the cartridge filter element 30.
