[0022] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0023] Embodiment 1:

[0024] Reference Figures 1 to 4 The present embodiment discloses a hanging device 1 for a discharge electrode 3 of an electrostatic precipitator. The electrostatic precipitator is provided with an electrode top grid 2. A hook 31 hung on the electrode top grid 2 is provided on the top of the discharge electrode 3. The hanging device 1 comprises a device body 11 and a connector 12. The device body 11 has a mounting groove 111 for accommodating the electrode top grid 2 and the hook 31. The device body 11 is detachably connected to the electrode top grid 2 through the connector 12, thereby locking the hook 31 to the electrode top grid 2. The device body 11 in the present embodiment can play a role in preliminarily fixing the hook 31 and the electrode top grid 2, and the connector 12 can indirectly play a role in strengthening the connection between the hook 31 and the electrode top grid 2, thereby making the hanging device 1 as a whole have a double locking effect, which can effectively prevent the discharge electrode 3 from falling off the electrode top grid 2, thereby solving the defects of the prior art.

[0025] Reference Figures 1 to 4 The bottom of the device body 11 is hollowed out to form an installation groove 111, and both ends of the device body 11 are provided with a clearance groove 112 for avoiding the electrode top grid 2, and a connecting piece 12 is provided to lock the electrode top grid 2 in the clearance groove 112. During installation, the hook 31 of the discharge electrode 3 is first hung on the electrode top grid 2, and then the installation groove 111 and the clearance groove 112 of the device body 11 are respectively aligned with the hook 31 and the electrode top grid 2, so that the device body 11 is covered outside the hook 31 and the electrode top grid 2, and finally the electrode top grid 2 is locked in the clearance groove 112 through the connecting piece 12, thereby indirectly locking the hook 31 on the electrode top grid 2. In this embodiment, there is no need to improve the structure of the discharge electrode 3 and the electrode top grid 2, and the overall structure of the hanging device 1 is simple, the design is reasonable, and the operation is convenient, so it can significantly reduce the production cost on the basis of effectively solving the problems of the prior art.

[0026] Reference Figures 1 to 4 The connecting member 12 includes a screw rod 121, a nut 122 and a limiting sleeve 123; mounting holes connected to the clearance groove 112 are provided on both sides of the device body 11, and both ends of the screw rod 121 are installed in the mounting holes through the nut 122, and the middle of the screw rod 121 passes through the clearance groove 112, and a limiting sleeve 123 is provided to abut against the bottom of the electrode top grid 2. The connection between the device body 11 and the electrode top grid 2 can be released by disassembling the connecting member 12, so as to facilitate the replacement of the discharge electrode 3, which is simple and convenient to operate and effectively improves the work efficiency.

[0027] Reference Figure 4The hook 31 has a U-shaped structure, the device body 11 has a rectangular structure, and the mounting groove 111 of the device body 11 is adapted to the shape of the hook 31. In order to ensure a better adaptation effect, the size of the mounting groove 111 should be slightly larger than the outer size of the hook 31.

[0028] Reference Figures 1 to 4 As a preferred solution, the device body 11 is made of polytetrafluoroethylene, and the connecting piece 12 is made of polytetrafluoroethylene or Hastelloy. Of course, other strong acid-resistant materials can also be used in practical applications, thereby effectively extending the service life of the hanging device 1.

[0029] Embodiment 2:

[0030] Reference Figure 5 Different from the first embodiment, countersunk holes 113 are provided on both sides of the device body 11 in this embodiment at corresponding positions of the mounting holes, so that the screw 121 and the nut 122 can be installed in the countersunk holes 113, so that both sides of the device body 11 are flat and have a higher aesthetics.
