[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses an antistatic polyester filter cloth.

[0024] Embodiment 1

[0025] Reference Figure 1-3 An antistatic polyester filter cloth comprises a filter cloth body 1 and metal conductive wires 12. The filter cloth body 1 is arranged in a ring shape, and a plurality of metal conductive wires 12 are respectively fixedly arranged on both sides of the filter cloth body 1. A support frame 4 is fixedly arranged on the inner side of the filter cloth body 1, and a rotating rod 5 is rotatably arranged on one side of the inner side of the support frame 4. A connecting block 6 is fixedly sleeved on the rod wall of the rotating rod 5, and a mounting block 2 is fixedly arranged on one side of the connecting block 6. An activated carbon strip 3 is abutted against the side of the mounting block 2 away from the rotating rod 5. A wedge-shaped groove is opened on the front side of the connecting block 6, and a wedge-shaped block 11 is clamped on the inner side of the wedge-shaped groove. One side of the wedge block 11 is fixed to the connecting block 6 with the activated carbon strip 3, and the front side of the mounting block 2 abuts against the inner wall of the support frame 4, so that the wedge-shaped block 11 can be stably clamped in the wedge-shaped groove.

[0026] Embodiment 2

[0027] Reference Figure 1-3 A limiting mechanism for limiting the rotation of the rotating rod 5 is arranged on one side, and the limiting mechanism includes a limiting tube 7 and a limiting rod 9. A cavity is opened inside the side of the mounting block 2 away from the activated carbon strip 3, and a slider 8 is slidably arranged inside the cavity. The limiting rod 9 is fixedly arranged on the side of the slider 8 away from the activated carbon strip 3, and the limiting tube 7 is fixedly arranged on the inner wall of the side of the supporting frame 4 away from the activated carbon strip 3. The limiting rod 9 is plugged into the limiting tube 7, and an avoidance hole is opened at the middle end of the rotating rod 5 and at a position corresponding to the limiting rod 9 to prevent the limiting rod 9 from interfering with the rotating rod 5 as much as possible.

[0028] Embodiment 3

[0029] Reference Figure 1-3 A spring 10 is fixedly provided on one side of the slider 8 away from the limiting rod 9, and the other end of the spring 10 is fixedly connected to the inner wall of the cavity to facilitate the reset of the slider 8. The longitudinal sections of the slider 8 and the cavity are both rectangular, so that the slider 8 cannot rotate, that is, it can slide stably.

[0030] In the utility model, when in use, since the metal conductive wires 12 are arranged on both sides of the filter cloth body 1, the static electricity on the filter cloth body 1 can be discharged, so that the filter cloth body 1 has good anti-static performance, can effectively reduce the adsorption of dust on the surface of the filter cloth body 1, and ensure the filtering performance of the filter cloth body 1. Since the activated carbon strips 3 are arranged on the inner side of the filter cloth body 1, the filtering and adsorption performance of the filter cloth body 1 can be further improved. After the activated carbon strips 3 are saturated, the limit rod 9 is pulled out of the limit tube 7, that is, the limit on the rotating rod 5 is released, and the rotating rod 5 is rotated to make the mounting block 2 and the activated carbon strips 3 rotate out of the supporting frame 4, that is, the wedge block 11 can be pulled forward from the wedge groove, that is, the saturated activated carbon strips 3 are conveniently replaced.
