Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
As shown in Figs. 1-3, the utility model provides a kind of long-life plasma flare cathode, is fixed on installation pedestal
On 5, including：Cathodic body 2 is detachably secured to the installation pedestal 5 by screw thread, the cathodic body 2 with it is described
The outer wall that installation pedestal 5 is affixed invaginates to form an annular groove；Positioning spigot 2-3 is set in institute for cyclic annular and fixation
It states on cathodic body 2, the left side of the positioning spigot 2-3 and the right side of the installation pedestal 5 offset；Annular permanent magnet 3,
It is set in for cyclic annular and fixation on the cathodic body 2, the left side of the annular permanent magnet 3 and the positioning spigot 2-3
Right side offset；First sealing ring 2-2, is fastened in the groove, and the both sides difference of the first sealing ring 2-2 is seamless
It is close to the cathodic body 2 and installation pedestal 5 one is enclosed.Cathodic body 2 is fixed on using screw thread 2-1 in installation pedestal 5, uses
One sealing ring 2-2 is sealed with installation pedestal 5, and uses positioning spigot 2-3 fixed negative poles ontology 2 and the position of installation pedestal 5
It puts, it is ensured that the distance between water inlet pipe 1 and cathodic body 2 are consistent, whole system are made to have good interchangeability, it is ensured that whole
Performance is stablized.An annular permanent magnet 3 is added on cathodic body 2, the electric arc on cathodic body is constrained using magnetic field,
Electric arc drop point 4-2 is reduced, promotes the cathodic body service life.
The cooling surface 4-1 of cathodic body 2 is round end taper.Cooling water can be made more unobstructed by cooling surface 4-1.It is cloudy
The cooling surface 4-1 of pole ontology 2 is round end pyramidal structure, is conducive to reach the water of the cooling surface 4-1 of cathodic body by water inlet pipe 1
Stream washes away cathodic body 2, and fast speed belt walks the heat that electric arc is transmitted to the pole-face of cathodic body.
The cathodic body 2 is internally provided with water inlet pipe 1, and the circulation area of the water inlet pipe 1 from left to right gradually becomes
Greatly.
The transition face of the inner cavity of the cathodic body 2 is respectively provided with rounded corner.All transition faces are required for rounded corner, in this way may be used
The cooling effect of cathodic body is influenced effectively to avoid the formation of cooling dead angle.
The front end 4 of the cathodic body is 50 ° -100 ° for cone platform and frustoconical bevel angle left large and right small.Cathodic body
It is designed to that the frustum of a cone is conducive to constraint of the air-flow to electric arc at front end 4.
A diameter of 10-25mm of the front end face of the frustum of a cone.The electric arc of cathodic body due to be by rotate air-flow into
Row constraint, the diameter of the front end face of the frustum of a cone is smaller, and heat of the arcing on cathodic body is with regard to smaller, the longevity of cathodic body
Life is longer.Since prolonged ablation can cause electric arc drop point 4-2 to deepen, and the front end face of the frustum of a cone can expand, circular cone
The diameter of the front end face of platform is too small to also result in that ablation is too fast, therefore the diameter of the front end face of the frustum of a cone is set as 10-25mm.
The minimum range of the cooling surface 4-1 of the cathodic body 2 and the front end face of the frustum of a cone is 10-25mm.It is described
The minimum range of the cooling surface 4-1 of cathodic body 2 and the front end face of the frustum of a cone need to be between 10-25mm, it is ensured that cathode has
Enough ablation amounts and good cooling effect, the diameter of cathodic body 2 can be adjusted as needed, control
Range is in 20-60mm.
The circulation area of water inlet is slightly less than the circulation area of return water.Be conducive to the uniformity of flow of cooling water in this way, it is ensured that
It can quickly be discharged after cooling water cooling cathodic body.Controlling the internal diameter of water inlet pipe 1, the internal diameter of cathodic body 2 exists in 8-20mm
14-40mm, it is ensured that the circulation area of 2 cooling water of cathodic body water inlet and the circulation area ratio of return water are 1：1 to 1:Between 1.2.
The section of the first sealing ring 2-2 is ellipse, and the first sealing ring 2-2 is the two of oval long diameter
End is seamless respectively and is relatively fixed the second sealing ring 2-4 that section is isosceles triangle, Formation cross-section for class ellipse the
Three sealing rings；Wherein, the vertex of the isosceles triangle of two the second sealing ring 2-4 is respectively with the first sealing ring 2-2 ellipse
The both ends of circular long diameter are fixed and positioned at homonymies.Third sealing ring has three seals, makes sealing effect more preferable.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modification is easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
