[0002] The cathode wire is one of the core components of the electrostatic precipitator, and the structural form of the cathode wire directly affects the dust removal and demisting efficiency of the electrostatic precipitator.

[0003] Patent No. CN203935911 U mentions a spiral cathode wire for an electrostatic precipitator, which includes a cathode wire body. The cathode wire body is formed by folding a sheet along its length direction into a Z-shaped cross-section in the width direction and then twisting it into a spiral shape. A pointed discharge tip is provided on the spiral part of the cathode wire body.

[0004] The cathode wire body adopts a spirally distributed discharge end to solve the problem of uneven cathode wire discharge. However, the cathode wire body adopts a sheet structure, which has high requirements for spiral installation. Moreover, the spirals after installation are long and short, and it is difficult to grasp the specific installation dimensions, resulting in uneven spiral structure after installation, which reduces the use effect of the cathode wire body. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a spiral cathode wire for an electrostatic precipitator, whose structure includes a cathode wire body, and connecting plates connected to the cathode frame are provided at both ends of the cathode wire body. The innovation point is that the cathode wire body is formed by two seamless tubes connected to the left and right, and the connecting plates are respectively stamped at the two ends of the cathode wire body, and a plurality of discharge nails are welded on the cathode wire body, and the discharge nails are distributed in a spiral shape along the length direction of the cathode wire body.

[0007] Furthermore, the ends of the two seamless pipes are respectively provided with a thread groove and a threaded rod matching the thread groove, and the two seamless pipes are respectively connected by the thread groove and the threaded rod.

[0008] Furthermore, the pitch between the above-mentioned discharge pins is 25 mm.

[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] like Figures 1 to 3 It is a specific embodiment of the utility model, and its structure includes a cathode wire body 1, and connecting pieces 2 connected to the cathode frame are provided at both ends of the cathode wire body 1. The cathode wire body 1 is formed by two seamless tubes 11 connected left and right, and the connecting pieces 2 are respectively stamped at both ends of the cathode wire body 1. A plurality of discharge nails 3 are welded on the cathode wire body 1, and the discharge nails 3 are spirally distributed along the length direction of the cathode wire body 1.

[0015] In the utility model, the cathode wire body 1 adopts a tubular structure, which is formed by two seamless tubes 11 connected to each other. In order to improve the uniformity of the discharge of the cathode wire body 1, the discharge nails 3 are distributed in a spiral shape on the cathode wire body 1. When the discharge nails 3 and the cathode wire body 1 are connected, since the cathode wire body 1 is a tubular structure, the discharge nails 3 are welded to the cathode wire body 1 by an automatic welding machine, which is not only convenient to operate, but also ensures the uniformity of the spiral distribution of the discharge nails 3 on the cathode wire body 1. At the same time, the two ends of the cathode wire body 1 can be formed into connecting pieces 2 by stamping, and the entire manufacturing process is simple and convenient.

[0016] In the utility model, in order to specifically illustrate the connection between the two seamless tubes 11, the ends of the two seamless tubes 11 are respectively provided with a thread groove 4 and a threaded rod 5 matching the thread groove 4, and the two seamless tubes 11 are respectively connected by the thread groove 4 and the threaded rod 5. The two seamless tubes 11 are directly connected by the thread groove 4 and the threaded rod 5, which is not only conducive to subsequent disassembly, but also facilitates the connection between the two seamless tubes 11.

[0017] In the present invention, the pitch between the discharge pins 3 is 25 mm. The selection of the pitch between the discharge pins 3 enables the cathode plate body to achieve the maximum use effect.
