[0002] PTFE (polytetrafluoroethylene) filter bags have excellent air permeability, high temperature resistance, corrosion resistance, extremely stable chemical properties, are almost non-flammable, and have an extremely long service life. They are widely used in flue gas filtration and dust removal in harsh working conditions such as power, metallurgy, biomass, waste incineration, solid waste disposal, and municipal waste dust removal.

[0003] Existing devices have some drawbacks in use. For example, when filter bags are covered with too much dust and are difficult to clean effectively, they can only be replaced manually one by one. Since there are usually a large number of these bags and they are distributed in various parts of the dust removal system, the replacement work is often time-consuming and requires a lot of manpower and resources. In addition, the dust removal system needs to be shut down and related equipment on the production line needs to be stopped during the replacement process, which will lead to production interruption and affect the company's production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a PTFE dust collector filter bag with a dust removal function, which solves the problem that the dust collection system needs to be shut down and related equipment on the production line needs to be stopped during the replacement process, which will lead to production interruption and affect the production efficiency of enterprises.

[0007] As a preferred embodiment of the above technical solution, the driving assembly includes a driving rod inserted into the top of the fixed cylinder, the bottom of the driving rod being threadedly connected to the fixed cylinder, the top of the driving rod passing through the top wall of the movable cylinder and having a knob fixedly connected to its end, and the top of the driving rod being rotatably connected to the top wall of the movable cylinder.

[0008] As a preferred embodiment of the above technical solution, all vibrators are electrically connected to an external controller.

[0009] As a preferred embodiment of the above technical solution, the outer wall of the contact plate has an arc-shaped structure for fitting the inner wall of the dust collector filter bag.

[0010] As a preferred embodiment of the above technical solution, a retaining ring is fixedly installed at the top of the dust collector filter bag.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a PTFE dust collector filter bag with a dust removal function, including a dust collector filter bag 1, a base 11 fixedly installed at the bottom end of the dust collector filter bag 1, a base 12 fixedly installed at the center of the upper end face of the base 11, a cleaning mechanism 2 for dust removal provided on the upper end face of the base 12, the cleaning mechanism 2 being located inside the dust collector filter bag 1, a drive assembly 3 for driving the cleaning mechanism 2 being connected to the cleaning mechanism 2, and a retaining ring 13 fixedly installed at the top end of the dust collector filter bag 1. In specific use, the dust collector filter bag is mainly composed of the dust collector filter bag 1, which uses high-performance PTFE. Made of TFE (polytetrafluoroethylene) material, it ensures excellent filtration efficiency and corrosion resistance. The top and bottom of the dust collector filter bag 1 are firmly installed with retaining rings 13 and chassis 11, respectively. This design enhances the stability of the filter bag. In actual use, when the filter bag begins to accumulate dust and affects its filtration efficiency, the cleaning mechanism 2 is driven by activating the drive assembly 3. The cleaning mechanism 2 then performs dust cleaning inside the filter bag, effectively removing dust from the surface of the filter bag. This process not only improves the filtration efficiency of the filter bag, but also extends its service life and reduces the frequency and cost of replacing the filter bag.

[0020] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the cleaning mechanism 2 includes a fixed cylinder 21 fixedly installed at the center of the upper end face of the base 12. A movable cylinder 22 is sleeved on the outside of the fixed cylinder 21. Multiple connecting sleeves 23 are fixedly sleeved on the outer wall of the movable cylinder 22. Linkage rods 24 are rotatably connected to the opposite outer walls of the multiple connecting sleeves 23. A contact plate 25 is rotatably connected to the end of the multiple linkage rods 24 away from the connecting sleeves 23. The outer wall of the contact plate 25 has an arc-shaped structure for fitting the inner wall of the dust filter bag 1. Limiting sliders 26 are fixedly connected to the bottom of the two contact plates 25. Rectangular plates 27 are fixedly connected to the opposite outer walls of the base 12. Limiting grooves 28 adapted to the limiting sliders 26 are opened on the upper end face of the rectangular plates 27. The limiting sliders 26 slide in the limiting grooves 28. Vibrators 29 are fixedly installed on the side walls of the two contact plates 25 near the fixed cylinder 21. The vibrators 29 are electrically connected to an external controller. The drive assembly 3 includes a drive rod 31 inserted into the top of the fixed cylinder 21. The bottom of the drive rod 31 is threadedly connected to the fixed cylinder 21, and the top of the drive rod 31 passes through the top wall of the moving cylinder 22 and is fixedly connected to the end of the knob 32. The top of the drive rod 31 is rotatably connected to the top wall of the moving cylinder 22. In specific use, when it is necessary to remove the dust on the inner wall of the dust collector filter bag 1, the external controller can be operated to start the vibrator 29, and the knob 32 can be rotated to drive the drive rod 31 to rotate and move up and down. The up and down movement of the drive rod 31 will drive the moving cylinder 22 to move accordingly, and then drive the contact plate 25 to move through the linkage rod 24. (When the limit slider 26 set at the bottom of the contact plate 25 is pushed, the limit slider 26 will slide in the limit groove 28, thus driving the contact plate 25 to move outward.) When the contact plate 25 moves to the end, it will be tightly attached to the inner wall of the dust collector filter bag 1, and the high-frequency vibration generated by the vibrator 29 will remove the dust on the inner wall of the dust collector filter bag 1. In this way, the dust can be effectively removed from the surface of the filter bag.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
