Abstract
The utility model discloses a hollow female and male buckle carbon graphite electrode, which comprises a cylindrical graphite electrode body, wherein a screw bolt which is formed into a whole body with the graphite electrode body is coaxially and convexly arranged on one end surface of the graphite electrode body, a screw nut which is formed into a whole body with the graphite electrode body is coaxially and concavely arranged on the other end surface of the graphite electrode body, the screw nut and the screw bolt are mutually matched, and the center of the graphite electrode body is provided with a through hole. The utility model reduces the energy consumption and improves the yield on the production, the electrode can bear higher current density when in use, the utilization rate of the electrode is improved, and the service life of the electrode is prolonged.
Description
Technical field
The utility model belongs to charcoal graphite electrode technical field, particularly a kind of hollow negative and positive button charcoal graphite electrode.
Background technology
Chinese patent ZL200820148457 discloses a kind of negative and positive button charcoal graphite electrode, this charcoal graphite electrode is solid column, existing in process of production deficiency is that the even and quality of big, the inside and outside density unevenness of power consumption can not guarantee etc., and the deficiency that exists in the use is that the current density of passing through is little, useful life is short etc.
The utility model content
The purpose of this utility model provides the low hollow negative and positive button charcoal graphite electrode of a kind of energy consumption.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of hollow negative and positive button charcoal graphite electrode, comprise the cylinder type graphite electrode main body, coaxial protrusion is provided with the bolt with its one on one end face of graphite electrode main body, be concaved with nut on the other end of graphite electrode main body in coaxial with its one, nut and bolt are suitable, and graphite electrode main center is provided with through hole.
Screw bolt and nut is all cylindrical or truncated cone.
The diameter of bolt is less than charcoal graphite electrode main body, and the nut external diameter is with charcoal graphite electrode main body.
Through-hole diameter is less than the diameter of bolt.
In the utility model, graphite electrode main center is provided with through hole, has reduced energy consumption on producing, and has improved output; Owing to increased the surface area of electrode, in use can make electrode bear bigger current density, improve the utilance and the useful life of electrode.
Description of drawings
Fig. 1 adopts the structural representation of truncated cone bolt, nut for the utility model;
Fig. 2 adopts the structural representation of cylindrical bolt, nut for the utility model.
Embodiment
Embodiment one: as shown in Figure 1, the utility model comprises cylinder type graphite electrode main body 1, bolt 2, nut 3 and through hole 4.Coaxial protrusion is provided with the truncated cone bolt 2 with its one on one end face of graphite electrode main body 1, be concaved with truncated cone nut 3 on the other end of graphite electrode main body 1 in coaxial with its one, graphite electrode main body 1 center is provided with through hole 4, and through hole 4 diameters are less than bolt 2 diameters.
Use the utility model, only need that bolt 2 is aimed at nuts 3 and screw in and get final product, repeat above-mentioned action as needs are a plurality of.Change negative and positive as needs and buckle the charcoal graphite electrode, the charcoal graphite electrode that is replaced is taken off, the bolt 2 of new charcoal graphite electrode is aimed at the nut 3 of previous charcoal graphite electrode, screw-in wherein; Then, the bolt 2 of a back charcoal graphite electrode is aimed at the nut 3 of new electrode, screw and get final product.
Embodiment two: as shown in Figure 2, the bolt 2 of different with embodiment one is embodiment two and nut 3 are for cylindrical.
