[0034] like Figure 2 As shown, the embodiment of the present invention provides a star-shaped bag cage for bag dust collector that is easy to clean and prevents compaction, including an upper end cover 1 and a lower end cover 2. A dust inlet pipe 201 is fixed to the middle of the upper end face of the lower end cover 2. A plurality of vertical vertical rods 3 are fixed around the edge of the upper end face of the lower end cover 2. A plurality of horizontal star-shaped ring ribs 4 are arranged along the vertical direction of the vertical rods 3. Figure 3 As shown, the star-shaped ring rib 4 is a ring structure with a concave edge, and the concave position of the star-shaped ring rib 4 is located between two adjacent vertical rods 3, so that the star-shaped ring rib 4 can reduce the wear on the filter bag compared to the circular ring support in the prior art, which is beneficial to increasing the service life of the filter bag.

[0035] like Figure 1 、 Figure 4 and Figure 5 As shown, the tops of the multiple vertical rods 3 jointly support a horizontal top ring 5, the inner wall of the top ring 5 is provided with an internal thread, and a vertical threaded barrel 6 is fixed to the lower end face of the upper end cover 1, and the outer edge face of the threaded barrel 6 is provided with an external thread, and the threaded barrel 6 is inserted into the top ring 5, so that the threaded barrel 6 can be raised and lowered on the top ring 5, thereby adjusting the height of the upper end cover 1, so that the distance between the upper end cover 1 and the lower end cover 2 can adapt to filter bags of different lengths and specifications, thereby improving the versatility of the bag cage.

[0036] At the same time, a plurality of vertical openings 601 are provided on the surface of the threaded barrel 6 . The openings 601 are evenly distributed in a circular shape on the side of the threaded barrel 6 to ensure the dust filtering area.

[0037] At least two fixing ears 501 are symmetrically fixed to the upper end surface of the top ring 5. Each of the fixing ears 501 is provided with a fastening bolt 503. The fastening bolt 503 is threaded through the fixing ears 501 and abuts against the outer edge of the threaded barrel 6, allowing the position and height of the threaded barrel 6 to be further fixed by the fastening bolt 503. Specifically, the outer side of each fixing ear 501 is provided with an engagement groove 502, and the bolt cap of the fastening bolt 503 is placed in the engagement groove 502 to prevent the fastening bolt 503 from protruding from the outside of the top ring 5 and contacting the filter bag, causing wear.

[0038] In addition, with Figure 6 As shown, the top ring 5 is a circular ring structure with an outwardly protruding edge, and the top end of the vertical rod 3 is supported on the outwardly protruding portion of the top ring 5. Therefore, the top ring 5 is located on the inner side of the vertical rod 3 and will not contact the filter bag, thereby ensuring the service life of the filter bag.

[0039] The working principle provided by the utility model is that the star-shaped bag cage of the bag-type dust collector is anti-caking and easy to clean. When in use, the star-shaped ring ribs 4 arranged inside the vertical rod 3 and the inner concave on the star-shaped ring ribs 4 can effectively avoid contact with the filter bag, thereby reducing the wear of the filter bag when disassembling and installing the filter bag, which is conducive to extending the service life of the filter bag.

[0040] At the same time, when the bag cage is in use, the position of the threaded tube 6 on the top ring 5 can be adjusted by screwing to adjust the distance between the upper end cover 1 and the lower end cover 2, so that the bag cage can be adapted to filter bags of different lengths and specifications, and has good versatility.

[0041] In summary, this device can not only reduce filter bag wear and extend the service life of the filter bag, but also facilitate height adjustment to adapt to filter bags of different lengths and specifications, and the overall use effect is good.
