According to the scheme, the corona motor in a wafer is matched with the cylinder to form a uniform electric field, but the wafer is easily oxidized and cracked in the discharging process, so that irregular point discharge is formed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mounting structure of circle sword electrode to solve the disk and by oxidation and splitting easily at the discharge process, and then form the problem of anomalous point discharge.

In order to achieve the above object, the utility model discloses a basic scheme provides a mounting structure of circle sword electrode, including conducting rod and a plurality of discharge electrode, still include short cover of a plurality of metals and two long covers of metal, the discharge electrode is the ring form and periphery thickness attenuation gradually, the discharge electrode, short cover of metal and the long cover of metal are all established on the conducting rod, the short cover of metal is located between two liang of discharge electrodes, two long covers of metal are located the conducting rod both ends respectively and offset with the discharge electrode in the outside, conducting rod both ends threaded connection has the short cover of messenger's metal, the long cover of metal and the nut that the discharge electrode supported tightly each other.

The principle of the basic scheme is as follows: the peripheral thickness of the discharge electrode is gradually reduced to form a tip, so that the electric field is uniformly distributed. The electrons are gathered at the tip, when the electric field reaches a certain degree, the electrons can escape and migrate, collide with the electrons of the opposite pole along the direction of the power line to generate plasma, and the discharge electrode is thick in whole thickness and only extremely small in peripheral thickness. The whole body has certain strength and is not easy to be oxidized and cracked, thereby avoiding the formation of irregular point discharge.

In addition, the annular discharge electrode is fixed on the conducting rod by the metal short sleeve and the metal long sleeve, so that the installation is convenient, the replacement is easy to disassemble, and the cost is saved in maintenance. Meanwhile, the short and long sleeves made of metal materials can play roles of structural fastening, good electric conduction and good contact with common organic glass sleeves.

The beneficial effect of this basic scheme lies in: 1. the special shape of the discharge electrode is utilized in the scheme, the whole discharge electrode has certain strength, and is not easy to be oxidized and cracked, so that irregular point discharge is avoided.

2. The installation mode in this scheme, simple to operate, quick detachable replacement has practiced thrift the cost in the maintenance.

3. The short and long sleeve made of metal materials in the scheme is relatively made of organic glass commonly used, and can play a role in fastening the structure, good conduction and good contact.
