Description

Technical Field

[0001] The invention relates to the technical field of cathode wires, in particular to a combined structure of a self-cleaning cathode wire and a thorn. Background Art

[0002] The cathode wire is a key component used in an electrostatic precipitator, usually made of corrosion-resistant metal materials. Its main function is to adsorb dust particles in the exhaust gas onto the cathode wire through the electrostatic field generated by high-voltage direct current, thereby achieving the purpose of exhaust gas purification.

[0003] The current cathode wire consists of a cathode wire body and multiple barbs. However, the multiple barbs on the current cathode wire are fixed to the surface of the cathode wire by direct welding. However, long-term operation of the cathode wire in an energized environment will cause dust to cover the surface of the cathode wire body and the multiple barbs. However, the covered dust requires personnel to take tools to clean it regularly.

[0004] Therefore, it is necessary to provide a self-cleaning cathode wire and thorn combination structure to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose a combination structure of a self-cleaning cathode wire and thorns, which solves the problem that multiple thorns on the current cathode wire are fixed to the surface of the cathode wire by direct welding, and the surface will be covered with dust after long-term use, requiring personnel to manually take tools to clean it.

[0006] To achieve the above-mentioned purpose, the present invention proposes a combination structure of a self-cleaning cathode wire and a barb, including a cathode wire main body, wherein the cathode wire main body is formed by fitting together an upper and lower main body, a barb that can freely move in a small range in three dimensions is arranged between the two main bodies, and a wire is connected between the cathode wire main body and the barb.

[0007] Preferably, the main body is an arc-shaped support body formed in one piece by stamping.

[0008] Preferably, the two main bodies are connected together by welding to form a tubular cathode wire body.

[0009] Preferably, a mounting hole for mounting a thorn is provided on the cathode wire body.

[0010] Preferably, grooves are provided on the butt joint edges of the body, and two corresponding grooves above and below cooperate to form a mounting hole.

[0011] Preferably, the thorn includes a base and thorn bodies located at two ends of the base.

[0012] Preferably, the thorn body is in a triangular shape, and the thorn body cannot pass through the mounting hole.

[0013] Beneficial effects of the present invention: The present invention forms a cathode wire body by combining an upper and a lower body together, and a three-dimensionally slightly movable barb is provided between the two bodies. A wire is connected between the cathode wire body and the barb. When the cathode wire body is vibrated for cleaning, relative vibration is generated between the barb and the cathode wire body, so that dust on the surface can be removed by vibration, thereby ensuring the discharge effect. Compared with the prior art, the present invention solves the problem that multiple barbs on the cathode wire are currently fixed on the surface of the cathode wire by direct welding, and the surface will be covered with dust after long-term use, requiring personnel to manually take tools for cleaning.

[0014] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example 1 See also Figure 1 , Figure 2 and Figure 3 The present invention discloses a self-cleaning cathode wire and barb combination structure, comprising a cathode wire main body (1), wherein the cathode wire main body (1) is formed by two upper and lower main bodies (6) being matched together, and a barb (3) that can move freely in a small range in three dimensions is arranged between the two main bodies, and a wire (4) is connected between the cathode wire main body (1) and the barb (3) to ensure electrical conduction.

[0018] The main body (6) is an arc-shaped support body formed in one piece by stamping.

[0019] The two main bodies (6) are connected together by welding to form a tubular cathode wire main body (1).

[0020] The cathode wire body (1) is provided with a mounting hole (5) for mounting the thorn (3).

[0021] The butt joint edges of the body (6) are each provided with a groove (2), and two corresponding grooves (2) above and below cooperate to form a mounting hole (5).

[0022] The thorn (3) comprises a base (31) and thorn bodies (32) located at two ends of the base (31).

[0023] The thorn body (32) is in a triangular shape, and the thorn body (32) cannot pass through the mounting hole (5).

[0024] The conductive wire 4 can be disposed in the inner cavity of the cathode wire body 1 and connected to the barb 3 .

[0025] The groove 2 is provided to facilitate installation of the thorn 3 . The thorn 3 is installed inside the groove 2 so that the thorn 3 can move freely. During vibration cleaning, relative vibration is generated between the thorn and the cathode wire body.

[0026] Example 2 See also Figure 4 and Figure 5 Based on a combination structure of a self-cleaning cathode wire and a barb provided in the first embodiment of the present application, the second embodiment of the present application proposes another combination structure of a self-cleaning cathode wire and a barb. The second embodiment is merely a preferred method of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0027] Specifically, the difference of the combination structure of a self-cleaning cathode wire and a barb provided in the second embodiment of the present application is that, in a combination structure of a self-cleaning cathode wire and a barb, a receiving groove 8 is provided on the cathode wire main body 1, and a barb 3 and a connecting component 7 located above the barb 3 are provided in the receiving groove, and the connecting component 7 includes a limit block 71, and positioning blocks 72 are connected to the left and right sides of the limit block 71, and the size of the limit block 71 is adapted to the size of the receiving groove 8, and positioning grooves 73 adapted to the positioning block 72 are provided on the two groove walls of the receiving groove 8.

[0028] When installing the thorn 3, first place the thorn 3 inside the receiving groove 8. After placing the thorn 3, move the limit block 71 with the positioning block 72 to the insertion end of the receiving groove 8. The limit block 71 corresponds to the receiving groove 8, and the positioning block 72 corresponds to the positioning groove 73. Then, push the limit block 71 to move to the inside of the receiving groove 8, and at the same time, move the positioning blocks 72 on both sides to the inside of the positioning groove 73.
