Description

Technical Field

[0001] This utility model relates to the technical field of long bag dust collector components, specifically a filter bag protection structure for a long bag dust collector. Background Technology

[0002] Long baghouse dust collectors primarily utilize filtration principles to remove dust particles from dust-laden gas. The dust-laden gas enters through the inlet of the dust collector, and under the action of a fan, the airflow passes through the filter bags. The filter bags are typically made of fibrous material with small pore sizes. As the gas passes through the filter bags, dust particles, because their size is larger than the pore size of the filter bags, are trapped on the inner or outer surface of the filter bags (depending on the inlet method), while the clean gas passes through the filter bags and is discharged from the outlet of the dust collector.

[0003] The existing filter bag protection structure of long bag dust collectors still has the following problems when in use: it usually adopts a frame-type protection structure to support and protect the filter bag. The protection frame usually includes multiple fixed rods set at equal angles, and multiple circular frames are fixedly fitted on the outer wall of the multiple fixed rods from top to bottom at equal intervals. The length of the overall protection frame is fixed, and it can only be assembled and protected with filter bags of matching length. It cannot be adapted to filter bags of different lengths, which is quite inconvenient. Utility Model Content

The fixed frame includes a plurality of first circular frames arranged at equal intervals from top to bottom. Two sets of first fixing rods are symmetrically fixedly connected between two adjacent first circular frames. Four sliding grooves are formed at equal angles between the upper and lower side walls of the first circular frames. Three first end blocks are fixedly connected at equal angles to the top of the uppermost first circular frame. The adjustment mechanism... The system includes an assembly ring fixedly connected to the top of three first end blocks. A through groove is formed between the upper and lower side walls of one end of the assembly ring, and a rotating sleeve is fixedly installed in the through groove.

After the overall frame structure is adjusted, the overall protective structure can be installed on the corresponding installation position of the long bag dust collector through the holes on its mounting sleeve 21 or mounting bracket 26 with the installation components. In addition, since both the movable frame 3 and the fixed frame 1 include multiple circular frames, and each circular frame has an anti-slip rubber strip fixedly connected to the middle of its annular outer wall, after the filter bag of the long bag dust collector is fitted and installed on the outside of the movable frame 3 and the fixed frame 1, the anti-slip rubber strip not only plays an anti-slip role with the filter bag, but also plays a protective role for the filter bag.
