Abstract
The utility model discloses a negative pole electric arc controller of a low-temperature plasma generator, which comprises a rotational flow piece body provided with central spray pipes along an axis. The rotational flow piece body comprises a rotational flow cylindrical section and a rotational flow circular cone section formed by contracting and extending along one end of the cylindrical section, and simultaneously spiral grooves are arranged on the outer surface of the rotational flow cylindrical section. Therefore, the position of a negative pole radial electric arc starting point can be changed ceaselessly under the condition that air pressure of compressed air entering a negative pole is constant, thereby avoiding fixed point burning loss of the electric arc starting point surface and greatly prolonging service life of the negative pole.
Description
Technical field
The utility model relates to a kind of cathode arc controller of low-temperature plasma generator, is applied in the plasma generator, produces rotation to impel the compressed air that gets into negative electrode.
Background technology
In the prior art, plasma generator commonly used, of Chinese patent 200620013110.2, the DC power supply that generally comprises negative electrode, anode, arc-initiating device and negative electrode, anode are connected; Negative electrode is connected to form by replaceable cathode taps and negative electrode conducting rod, and replaceable cathode taps is the cylinder barrel shaped structure, and is processed with the water-cooled cannelure on this replaceable cathode taps; Anode is hollow cylindrical shell, and set inside is Rafael nozzle formula structure, and the periphery then forms the water-cooled cannelure with the stainless steel sleeve tube.Such plasma generator structure is huge, complicated; Inconvenient maintenance.Simultaneously, the point-to-point generation electric arc mode that this plasma generator adopts is prone to cause electrode damage, has influenced the useful life of anode and cathode.
Therefore; Be necessary to provide a kind of plasma generator of new structure, through anode assemblies structure, cathode component architecture and the anode assemblies of change plasma generator and the syndeton between the cathode assembly, to simplify the structure of plasma generator; Be convenient to maintenance, practice thrift cost.
The utility model content
The utility model is to the deficiency of prior art; A kind of cathode arc controller of low-temperature plasma generator is provided; It is under the constant condition of compressed air air pressure; The negative electrode radially position of electric arc arcing point ceaselessly changes, and avoids the fixed point scaling loss on electric arc arcing point surface, the useful life of greatly improving negative electrode; Under the condition that changes compressed air air pressure, cathode axis to the position of electric arc arcing point integral body move down or on move, change the arcing point of whole starting the arc end face, increase the working face of negative electrode, can effectively prolong the useful life of negative electrode; In addition, under the condition that compressed air air pressure changes, can change the shape and the temperature of low temperature plasma torch, increase the means that the low temperature plasma torch is regulated.
For realizing above technical purpose, the utility model is taked following technical scheme:
A kind of cathode arc controller of low-temperature plasma generator comprises eddy flow spare body, and this eddy flow spare body offers core jet pipe along axis; Said eddy flow spare body comprises the eddy flow cylindrical section and extends the eddy flow conical section that forms along the end contraction of cylindrical section that simultaneously, the outer surface of said eddy flow cylindrical section is offered helicla flute.
Said core jet pipe is by boring the section jet pipe and forming along the shell of column jet pipe that awl section jet pipe carefully holds extension to form, and said shell of column jet pipe is opened in the eddy flow conical section, and an awl section jet pipe then is opened in the eddy flow cylindrical section.
The big end of said jet pipe is the jet pipe air inlet, and the thin end of jet pipe then is the jet pipe gas outlet.
According to above technical scheme, can realize following beneficial effect:
The utility model is offered helicla flute at the eddy flow cylindrical section outer surface of eddy flow spare body; The compressed air that can cause getting into negative electrode rotates; Under the constant condition of compressed air air pressure; The negative electrode radially position of electric arc arcing point ceaselessly changes, and avoids the fixed point scaling loss on electric arc arcing point surface, the useful life of greatly improving negative electrode; Under the condition that changes compressed air air pressure, cathode axis to the position of electric arc arcing point integral body move down or on move, change the arcing point of whole starting the arc end face, increase the working face of negative electrode, can effectively prolong the useful life of negative electrode; In addition, under the condition that compressed air air pressure changes, can change the shape and the temperature of low temperature plasma torch, increase the means that the low temperature plasma torch is regulated.

Embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation; Below will combine accompanying drawing that the technical scheme of the utility model at length is described.
Shown in Fig. 1 to 3, the cathode arc controller of the said low-temperature plasma generator of the utility model comprises eddy flow spare body, and this eddy flow spare body offers core jet pipe along axis; Said eddy flow spare body comprises the eddy flow cylindrical section and extends the eddy flow conical section that forms along the end contraction of cylindrical section that simultaneously, the outer surface of said eddy flow cylindrical section is offered helicla flute.Said core jet pipe is by boring the section jet pipe and forming along the shell of column jet pipe that awl section jet pipe carefully holds extension to form, and said shell of column jet pipe is opened in the eddy flow conical section, and an awl section jet pipe then is opened in the eddy flow cylindrical section.The big end of said jet pipe is the jet pipe air inlet, and the thin end of jet pipe then is the jet pipe gas outlet.
When then installing, a part of compressed air that the cathode inlet mouth feeds is handled through the further compression-expansion of core jet pipe, goes out from the central-injection of eddy flow spare body; The helicla flute rotation that another compressed air is then offered along eddy flow spare body outer rim, both combinations can ceaselessly change the radially position of electric arc arcing point of negative electrode, avoid the fixed point scaling loss on electric arc arcing point surface, the useful life of greatly improving negative electrode.
