Description
Technical field
The utility model relates to a kind of hot stove in ore deposit that is used for products such as smelting commercial silicon, various ferroalloy and yellow phosphorus, and a kind of especially is the feedthrough electrode electric installation of the hot stove in ore deposit.
Background technology
The feedthrough electrode electric installation of traditional hot stove in ore deposit is held tightly electrode by the brasses of casting or forging.Conductive plate very easily damages, and is the consumable accessory that the hot stove in ore deposit often will be changed.Electrical efficiency is low on the one hand, causes the blowing out loss because of changing brasses on the other hand, and production efficiency is low, the production cost height.Applicant two during the last ten years, be devoted to the research transformation of the hot stove in ore deposit always, by my patent No. of application is 93243564.5, Granted publication number is CN2172558Y, Granted publication day is the feedthrough electrode electric installation that the Chinese utility model on July 20th, 1994 discloses the hot stove in a kind of ore deposit, this feeder equipment has installed cooling jacket additional in the periphery of brasses, cooling jacket is provided with water inlet and delivery port, water inlet, delivery port respectively with water inlet copper pipe, the water outlet copper pipe is connected, cooling water enters cooling jacket from water inlet, discharge from delivery port, thereby realize cooling, prolonged the useful life of conductive plate conductive plate.Though cooling jacket fits tightly the outer wall that is located on conductive plate, because of being two parts, cooling-down effect also is not very good, and the electrical efficiency of the hot stove in ore deposit is still waiting to continue to excavate.Utility model content the technical problems to be solved in the utility model is to provide a kind of long service life, the feedthrough electrode electric installation of ore deposit hot stove electrical efficiency height, the hot stove in ore deposit that production efficiency is high.
The utility model solves the problems of the technologies described above the technical scheme of being taked: the feedthrough electrode electric installation of the hot stove in a kind of ore deposit comprises electrode, graphite lining, conductive plate and cooling jacket; It is characterized in that: the one side that cooling jacket is corresponding with the graphite lining is a conductive plate, and conductive plate is the part of cooling jacket, and conductive plate and cooling jacket are one.
The utility model is easy to manufacture, cost is low.Because of conductive plate and cooling jacket are one, the cooling extent of conductive plate improves greatly, in other words, cooling water improves greatly to the cooling-down effect of conductive plate, and the heating temperature of conductive plate is reduced, and is splendid to the cooling effect of the graphite lining that fits tightly with conductive plate, the electrical efficiency of the hot stove in ore deposit is further improved, just the power consumption of specific yield reduces, and the experiment proved that, its power consumption is saved 20～30%; Improved the useful life of conductive plate greatly, made conductive plate become durable, not only reduced consumption, and greatly reduced to changing conductive plate and caused the hot stove power failure in ore deposit, blowing out number of times and time, made a price reduction production cost significantly from consumable accessory.

Embodiment
As Fig. 1 and shown in Figure 2: the feedthrough electrode electric installation of the hot stove in a kind of ore deposit comprises electrode 1, graphite lining 2, conductive plate 3 and cooling jacket 4; Cooling jacket 4 is made of two parts, and connecting bolt 6 connects two parts of cooling jacket 4 solid; Every part of cooling jacket 4 is independently containers, and every part is provided with water inlet 401 and delivery port 402 separately, and recirculated water cooling copper pipe 5 is connected with delivery port 402 with water inlet 401; Referring to Fig. 3: it is conductive plates 3 that copper alloy is made that cooling jacket 4 and graphite serve as a contrast the 2 corresponding sides, and conductive plate 3 is parts of cooling jacket 4 integral body, and conductive plate 3 is an one with cooling jacket 4.In other words, be to serve as a contrast the 2 corresponding sides at cooling jacket 4 and graphite to be provided with breach, 3 solid weldings of copper alloy conductive plate at this breach, are crammed polishing to breach, conductive plate 3 is faces of cooling jacket 4.
Like this, conductive plate 3 directly contacts with the recirculated cooling water of cooling jacket 4 the insides, and recirculated cooling water is directly lowered the temperature to conductive plate 3, and the cooling effect of the graphite lining 2 that fits tightly with conductive plate 3 is very good.
Shown in Figure 4 is the structural representation of traditional feeder equipment, casting or brasses 3 (identical) the banding electrode 1 that forges with conductive plate 3 effects, conical ring 7 is sleeved on the periphery of brasses 3, installs drift 8 additional and make between each parts and closely cooperate between conical ring 7 and brasses 3, thereby brasses 3 is held tightly electrode 1.
Referring to Fig. 5: as change, cooling jacket 4 peripheral suit conical rings 7 install drift 8 additional between conical ring 7 and the cooling jacket 4 to the utility model to existing conical ring 7, make conductive plate 3 and graphite serve as a contrast 2 between, graphite serve as a contrast 2 and electrode 1 between tightr obvolvent.
Referring to Fig. 1 and Fig. 5: as of the present utility model perfect, the bottom of cooling jacket 4 is fixed with stainless protection layer 9 with affixed bolt 10.Like this; the direct calcination of stove fire can not damaged the steel plate of cooling jacket 4 bottoms by the direct calcination of stove fire to stainless protection layer 9, thereby prolongs the useful life of cooling jacket 4; shortening is further increased economic efficiency because of the hot stove interruption duration in ore deposit that maintenance cooling jacket 4 causes.
Above-mentioned execution mode is not meaned to restriction of the present utility model, vary in size according to the hot stove installed capacity in ore deposit, graphite lining 2, cooling jacket 4 that electrode 1 periphery encircles, certainly also comprise as the conductive plate 3 that constitutes cooling jacket 4 parts, three's quantity can not wait by two～eight, and, graphite lining 2 is not necessarily identical with the quantity of cooling jacket 4, graphite lining 2 is not necessarily identical with the quantity of conductive plate 3 yet, the described graphite lining 2 of present embodiment is four, cooling jacket 4 is that two parts are formed, and a part of cooling jacket 4 has two conductive plates 3.For four graphite linings 2 of embodiment, cooling jacket 4 also can be the periphery that four independent part rings are contained in four graphite linings 2, and a conductive plate 3 is arranged on every part cooling jacket 4.
