Technical Field

[0001] This utility model relates to the field of filter bag anti-accumulation and flow guiding technology, specifically to a filter bag bottom anti-accumulation and flow guiding device. Background Technology

[0002] Filter bags are a common type of filtration equipment, typically made of fibrous materials (such as polyester, polypropylene, nylon, etc.), used to remove solid particles, impurities, or contaminants from liquids or gases. They are widely used in industries such as chemical, pharmaceutical, food, water treatment, and environmental protection to ensure product quality, protect equipment, or meet environmental requirements.

[0003] To prevent solid particles from accumulating at the bottom of existing filter bags and affecting filtration efficiency, anti-accumulation diversion devices are typically installed inside the filter bags. However, some of these devices have overly complex designs, making cleaning or replacement extremely inconvenient, which not only increases maintenance costs but also consumes a significant amount of time. Therefore, we propose an anti-accumulation diversion device for the bottom of filter bags to solve the aforementioned problems. Utility Model Content

Multiple filter bag clamping blocks 102 are uniformly rotated and fixedly connected to the inner side of the filter bag slot 101 around the axis. In this example, by setting multiple filter bag clamping blocks 102, the fixing tube 1 and the filter bag can be fixed, which facilitates installation.

[0026] Multiple movable ring holes 201 are evenly rotated around the axis on the movable ring 2, and the lower surface of the movable ring 2 is in contact with the top of the fixed tube 1.

[0027] The outer side of the drain plate 6 is provided with a drain plate slope 601, and the inner side of the drain plate 6 is provided with a cleaning hole 602. The drain plate 6 is fixedly connected to the pipe body 301. The drain plate slope 601 is inclined downward from the inside to the outside, and multiple drain plate holes 603 are uniformly arranged around the axis on the drain plate slope 601.
