Abstract
The utility model relates to a water-cooling conducting connecting device for metallurgical smelting equipment and belongs to the industry of manufacturing metallurgical equipment. A conductive body is into a taper hole on a joint body, an inner taper sleeve is arranged between the conductive body and the joint body, a nut installed on the conductive body is spirally connected with the external surface of the joint body, the end socket of the inner taper sleeve coming in contact with the nut is a right-angle plane, tighter contact can be formed between the inner circle surface of the inner taper sleeve and the conductive body as well as between the external tapered surface of the inner taper sleeve and the joint body, and the conducting are of a stressed part is more than two times of that of the sectional area of the conductive body, therefore the water-cooling conducting connecting device for metallurgical smelting equipment achieves high conduction efficiency, avoids arc strike and easy damage, and prolongs the service life.
Description
Technical field
The utility model relates to metallurgical smelting equipment water-cooled conductive connecting device, is the intermediate of current delivery, belongs to the metallurgical equipment manufacturing.
Background technology
Copper pipe in transformer that the metallurgical smelting equipment of China is commonly used and short net, short net and the stove, its jockey is the inner cone nested structure basically: electric conductor inserts in the taper hole of joint body, be equipped with inner conical drogue between electric conductor and joint body, the nut and the joint body outer surface that are installed on the electric conductor spin.The inner conical drogue structure is to be compressed by male cone (strobilus masculinus) and the joint body inner conical surface of joint body with inner conical drogue by nut, while inner conical drogue circular arc endoporus compressing owing to inner conical drogue, endoporus shrinks, electric conductor in the inner conical drogue endoporus is compressed, and electric conductor is by the inside and outside disc contact of inner conical drogue delivered current like this.The deficiency that exists is that the inner conical drogue termination that contacts with nut has one 45 chamferings of spending, like this, the inner conical drogue termination becomes 45 degree with the stress surface of nut, the axial force of nut is divided into two component, thrust has only half of axial force, and in the use, the conductive contact surfaces loose contact that can cause inadequately being correlated with because of thrust influences electrical efficiency, make water-cooled cable, water-cooled compensator beat the arc phenomenon because of contacting bad generation, useful life is not long.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of metallurgical smelting equipment water-cooled conductive connecting device is provided, make the axial thrust of nut be approximately equal to the thrust of inner conical drogue, thereby make thrust increase one times, significantly improved electrical efficiency with respect to background technology.Main innovation is that 45 degree chamferings of the inner conical drogue termination that will contact with nut remove, and the inner conical drogue termination is made right-angle plane into, like this, can make the axial thrust of nut be approximately equal to the thrust of inner conical drogue.It specifically is to implement like this: metallurgical smelting equipment water-cooled conductive connecting device, electric conductor inserts in the taper hole of joint body, be equipped with inner conical drogue between electric conductor and joint body, the nut and the joint body outer surface that are installed on the electric conductor spin, and it is characterized in that the inner conical drogue termination that contacts with nut is a right-angle plane.
The external diameter of inner conical drogue endoporus and electric conductor is gapped, in order to make the better of their contacts, on inner conical drogue, axially offer the wide notch of 6-8 road 1-1.5mm, wherein have is that holoaxial is to disconnection together, leave spacing distance between remaining notch bottom and inner conical drogue end face, this spacing distance is good with 8-12mm generally in actual making.Offer this notch and help the distortion of inner conical drogue, under the compressing of nut, contact with electric conductor better, can not influence very much conductive area again simultaneously.
This device can make the inner headed face of inner conical drogue contact tightlyer with the male cone (strobilus masculinus) of electric conductor, inner conical drogue with joint body, the conductive area at stressed place is more than 2 times of electric conductor sectional area, the electrical efficiency height, can not beat arc, not fragile, increase useful life, can be widely used in smelting industries such as arc furnace, refining furnace, furnace of calcium carbide, ferro-alloy furnace, industrial silicon furnace, yellow phosphorus stove.
