Description
Technical field
This utility model is related to a kind of arc channel, more particularly to a kind of plasma-arc passage, belongs to plasma apparatus
Technical field.
Background technology
In modern hot-working field, the processed and applied such as welding, cutting, thermal spraying, Surface heat-treatent is extensive.With science
The continuous development of technology, traditional processing technique is difficult to meet the processing request of new material and special construction.Conventional biography
System thermal source such as alkynes oxygen flame, oxyhydrogen flame application is easy, low cost, but its maximum temperature only has 3000 degrees centigrades, it is difficult to process
Refractory metal, high temperature ceramic material；The thermal source produced using arc discharge is used for welding field, technology maturation, but right
But it is difficult in special welding and ceramics, the welding of composite.In decades recently, the research of high energy beam thermal source is quick to be sent out
Exhibition, is most widely used with the research of laser, electron beam, hot plasma, and these three hot-fluids all have very high energy density,
Processing temperature is high, quick heating.Wherein, laser morning machining accuracy is high, but laser high cost, and one-time investment is big, power also compared with
Little, at present industrial semiconductor pump laser peak power is 10KW or so, adds energy transformation ratio low（20% or so）, pole
Limit other greatly industrial to promote the use；Electron beam produces heat energy using the electron bombardment workpiece of acceleration mode, belongs to essence
Degree fine machining method, but processing conditionss are complicated, need a whole set of special equipment and vacuum system, it is expensive, and electron beam
The X-ray that bombardment material is produced can damage human body cell, and safety problem can not be ignored.Heat plasma technology will be general using electric energy
Ventilation volume ionization makes plasma carry energy and be transferred to workpiece to produce plasma, compares with laser and electron beam, has
There is processed and applied simple, equipment cost is low, the advantages of safe.
And in hot plasma is arranged, generator is the core apparatus of plasma system, generator includes base, electricity
Pole, arc channel, chiller and nozzle etc..In arc plasma emission process, a large amount of high temperature, very fast electric arc can be produced
Beam-plasma, these arc plasma beams can pass through arc channel, mixed and disorderly entrance external environment to adversely affect.
Utility model content
This utility model aims to solve the problem that the problems referred to above, and proposes a kind of plasma-arc passage.By to arc channel
The new of device is related to, and solves destruction of the arc plasma to arc channel, also solves the shadow of arc plasma environment to external world
Ring.
In order to solve prior art problem, following technical scheme is proposed：
A kind of plasma-arc passage, one end connection generator base, other end connection generator nozzle, its feature exists
In：The arc channel is double-decker, including inner-layer device and outer layer device, the inner-layer device is provided with grid arc extinguishing
Room；The outer layer device is insulating barrier, and in outer layer device chiller is provided with.
Further, the grating arc-extinguishing chamber includes contact, spring, circuit, contact connecting spring.
Further, wear-resisting, exotic material is scribbled on the inner layer wall.
Further, the cooling medium in the chiller is soft water.
Grating arc-extinguishing chamber's principle is：
In AC low-tension device for switching, when electric arc is produced between contact, electric arc quilt under the contractility effect of the magnetic line of force
Draw in arc extinguishing grid pieces.One long arc is divided into multistage short arc.When alternating current zero passage, all short arcs extinguish simultaneously, due to
, all there is immediately the starting medium intensity of 150-250V in nearly cathode effect near the negative electrode of every section of short arc, as long as all series connection are short
The starting medium intensity summation of arc will no longer restrike more than the applied voltage between contact, electric arc.
Using the technical program, the Advantageous Effects for bringing are：
In this utility model, by the new setting to arc channel, orderly the entering of pilot arc beam-plasma is sprayed
Mouth；When part high temperature, quick arc plasma contact arc passage, effectively prevent arc plasma from outwardly transmitting,
And the impact to external world of cut-off high temperature.Wear-resisting, exotic material is scribbled on inner layer wall, arc plasma is prevented in arc channel
The impact of wall, is also prevented from corrosion of the high temperature to inwall；Cooling medium is soft water, can be recycled, and effectively avoids cooling water
Calcification postadhesion affects appliance arrangement on chiller wall.
