[0002] A Chinese patent discloses a dust collector and its metal filter bag (application number: CN201520860098.8). The dust collector includes a dust collector shell and a filter bag mounting plate with mounting holes disposed inside the dust collector shell. Metal filter bags are arranged in concentric rings on the filter bag mounting plate from the center outwards. The metal filter bags are arc-shaped plates or cylinders formed by bending a filter plate. Each ring of the filter bag mounting plate includes multiple arc-shaped plates or one cylinder, where "multiple" refers to at least two arc-shaped plates. The filter plate is a hollow filter plate with one open end, surrounded by a porous metal membrane. An air-permeable support frame supporting the porous metal membrane is provided inside the hollow filter plate. The open end of the bent filter plate is fixed to the corresponding mounting hole. In addition, a metal filter bag for the above-mentioned dust collector is also disclosed. This invention increases the effective filtration area of ​​the dust collector and improves the filtration accuracy of the metal filter bag while ensuring the service life of the filter bag.

[0003] Existing cleaning methods often employ pulse jet cleaning or mechanical vibration, but these methods often suffer from incomplete cleaning, easy damage to filter bags, and high maintenance frequency. In particular, they are not effective at cleaning the inside of filter bags, making it difficult to meet the requirements of high efficiency and continuous operation.

[0004] Therefore, a well-structured and highly efficient anti-clogging filter bag structure is needed to achieve simultaneous cleaning of the inner and outer walls of the filter bag, improve the cleaning effect, extend the service life of the filter bag, and ensure the long-term stable operation of the metal bag dust collector.

[0022] like Figure 1-5 As shown, this utility model provides an anti-clogging filter bag structure for a metal bag dust collector, including a filter cylinder 1. An auxiliary ring 2 is provided on the outside of the filter cylinder 1. A rotating block 8 is rotatably provided inside the auxiliary ring 2. Friction strips 803 are evenly provided on the outside of the rotating block 8 along the circumferential direction, penetrating into the inside of the filter cylinder 1. A support fixing ring 3 is fixedly connected to the outside of the filter cylinder 1. A movable strip 4 is provided on one side of the support fixing ring 3. The movable strip 4 is slidably provided on the outside of the filter cylinder 1. A protruding plate 401 is provided on the outer circumference of the movable strip 4. A telescopic strip 402 is fixedly connected to one side of the movable strip 4. The telescopic strip 402 penetrates the support fixing ring 3. Cleaning rings 6 are evenly and equidistantly provided on the outside of the telescopic strip 402. An extension block 7 is provided on the outside of one of the protruding plates 401.

[0023] The internal rotating cleaning structure of this utility model can effectively remove dust accumulated on the inner wall of the filter bag, while the external reciprocating cleaning structure performs periodic dust removal on the outer wall. The two work together to achieve all-round dust removal, avoiding clogging caused by dust accumulation; real-time removal of dust adhering to the surface of the filter bag reduces the risk of clogging caused by increased filter bag pressure difference, reduces replacement frequency, and extends the service life of the filter bag. Example 2

[0024] like Figure 1-3As shown, the filter cylinder 1 has through holes 101 evenly arranged around its circumference. The filter cylinder 1 is fixedly connected to the auxiliary ring 2, and a stabilizing ring 102 is fixedly connected to the other end of the filter cylinder 1.

[0025] Specifically, the stabilizing ring 102 is used to enhance the structural stability of the filter cylinder 1 and prevent it from deforming under high-intensity working conditions. It is made of high-strength metal to ensure that it is not easily deformed under high-intensity working conditions.

[0026] In this embodiment, the auxiliary ring 2 has a stabilizing hole 201 that communicates with the filter cylinder 1 inside, and the auxiliary ring 2 has a supporting groove 202 inside the stabilizing hole 201.

[0027] Specifically, the support groove 202 is used to facilitate the connection of the rotating block 8. Example 3

[0028] like Figure 2 and Figure 4 As shown, the filter cylinder 1 is fixedly connected to the support ring 3, the movable strip 4 is slidably connected to the filter cylinder 1, the movable strip 4 is fixedly connected to multiple protruding plates 401, an auxiliary spring 5 is fixedly connected between the protruding plate 401 and the auxiliary ring 2, and the extension block 7 is fixedly connected to the protruding plate 401.

[0029] Specifically, the return spring provides restoring force after the movable bar 4 is displaced, causing it to return to its original position, and the protruding plate 401 provides auxiliary support when the movable bar 4 slides. The movable bar 4 can be driven to vibrate by connecting an external vibration source to the extension block 7.

[0030] In this embodiment, the other end of the movable strip 4 is fixedly connected to the telescopic strip 402, and cleaning rings 6 are provided at equal intervals on the outside of the telescopic strip 402, and the cleaning rings 6 are in contact with the surface of the filter cylinder 1.

[0031] Specifically, by making contact between the filter cylinder 1 and the cleaning ring 6, the accumulation of dust inside the filter cylinder 1 can be easily controlled, reducing the risk of clogging and improving dust removal efficiency. Example 4

[0032] like Figure 1 and Figure 5 As shown, a sliding strip 801 is fixedly connected to the outside of the rotating block 8. The sliding strip 801 is rotatably and slidably connected to the inner wall of the support groove 202. Rotating gears 802 are evenly spaced on the outside of the rotating block 8. The rotating block 8 is fixedly connected to the friction strip 803.

[0033] During use, the rotating wheel drives the rotating block 8 to rotate, causing the friction strip 803 to contact the inner wall of the filter cylinder 1, effectively removing adhering dust and ensuring that the filter is unobstructed.

[0034] In summary, this application provides a rotating cleaning structure on the inner wall of the filter cylinder 1 and a reciprocating cleaning structure on the outside of the filter cylinder 1. Through the synergistic effect of the internal and external dual cleaning mechanisms, efficient dust removal is achieved, the service life of the filter is extended, and the stable operation of the equipment is ensured.
