Plasma surface treatment device

Abstract

The invention discloses a plasma surface treatment device. The device comprises a motor, a plasma gun head, an electrode and an inner core, wherein an output shaft of the motor is a hollow shaft; the inner core consists of a hollow cylinder and a transverse plate which is positioned at the rear end of the hollow cylinder; the transverse plate and the hollow cylinder are integrally arranged; the hollow cylinder is positioned in the hollow shaft; the transverse plate is fixedly arranged on a rear cover of the motor; an air pipe is led into the inner core through an air pipe hole in the transverse plate; a power line is connected to the electrode through the inner core; the plasma gun head is connected with the hollow shaft, covers the electrode and is provided with a tilted head nozzle. The plasma gun head is driven to rotate by directly utilizing the hollow shaft of the motor; compared with the contact type transmission of a conventional synchronous belt, gear or the like, the device has the advantages of capability of reducing the loss of a transmission step, simple structure, less parts and low cost.

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a plasma surface treatment device. Background technique [0002] Plasma, also known as plasma state. Substances in the plasma state have properties similar to gaseous states, such as good fluidity and diffusivity. However, since the basic constituent particles of plasma are ions and electrons, it also has many properties different from gaseous states, such as good electrical conductivity and thermal conductivity. In particular, according to scientific calculations, the specific heat capacity of plasma is proportional to temperature, and the specific heat capacity of plasma at high temperature is often hundreds of times that of gas. Therefore, the application of plasma is very wide, from our daily life to industry, agriculture, environmental protection, military, aerospace, energy, celestial bodies, etc., it has very important application value. [0003] With the continuous adv...
