Abstract
The invention discloses an electric calcining furnace for high-temperature graphitization. The electric calcining furnace comprises a furnace body (1), an upper-part electrode (2), a lower-part electrode (3), a lining (4), a multistage cooling device (5), a discharging device (6), a control system (7), a power supply rectifying device (8) and a feed bin (9). The electric calcining furnace is characterized in that the upper-part electrode (2) and the lower-part electrode (3) are arranged in the furnace body (1); the feed bin (9) is arranged on the furnace body (1) so as to feed raw materials into the furnace; and the cooling device (5) and the discharging device (6) are arranged under the furnace body (1) and are used for cooling and discharging a product. According to the electric calcining furnace for graphitization, graphitized petroleum coke or graphitized anthracite can be produced from petroleum coke or anthracite which serves as a raw material. The product has a broad usage prospect.
Description
Technical field
The present invention relates to a kind of high temperature graphitization electricity forge furnace, belong to carbon technique field.
Background technology
Electricity forge furnace is a kind of vertical resistance furnace relatively simple for structure, power by being arranged on the upper and lower two end electrodes of furnace interior, utilizing the resistance of material itself to form current circuit, is heat energy by electric energy conversion, when isolated air by heating material to high temperature, to reach calcining effect.
Early stage electric forge furnace combustion chamber temperature is only about 1800 DEG C, only can for the production of after-smithing petroleum coke/hard coal.About 2000 domestic beginning electricity consumption forge furnace production greying refinery cokes or greying hard coal goods, Chinese patent CN200510136353.5 describes electricity consumption forge furnace production greying refinery coke/anthracitic method, although this patent claims combustion chamber temperature now can reach about 1700 ~ 3000 DEG C, do not relate to the structure of electric forge furnace itself.Utility model 201320118977.4 describes a kind of liner form that can be used for about 2000 ~ 2500 DEG C.
In recent years, along with widely using of aluminium high graphite negative electrode, and the demand of steel-smelting carburant constantly increases, and greying refinery coke/hard coal has wide market outlook.
Summary of the invention
The object of the invention is to, by the improvement of original electric forge furnace up/down portion electrode, power-supply rectifying device, liner, the top temperature of burner hearth combustion chamber is promoted to about 2700 ~ 3000 DEG C, each position all can abundant greying in stove to make material, reaches production greying refinery coke/anthracitic object.
Technical scheme of the present invention: comprise body of heater (1), upper electrode (2), lower electrode (3), liner (4), refrigerating unit (5), discharge device (6), Controlling System (7), power-supply rectifying device (8), feed bin (9).It is characterized in that: each one of the configuration upper electrode (2) in body of heater (1), lower electrode (3); In stove, raw material is allocated at body of heater (1) top configuration feed bin (9) and blanking device (10); And body of heater (1) below is furnished with refrigerating unit (5) and discharge device (6) for cooling and discharge product.
accompanying drawing explanation
Fig. 1 is the common electric forge furnace body diagrammatic cross-section of tradition;
Body schematic diagram when Fig. 2 is high temperature graphitization of the present invention electricity forge furnace employing Graphite Electrodes.
Embodiment
Embodiment 1: as shown in Figure 2, up/down portion of the present invention electrode is 1, all adopts Graphite Electrodes, to bear larger electric current.The more common electric forge furnace of liner heat-insulating property is better, with to ensure in burner hearth interpolar everywhere temperature can reach 2300 ~ 3000 DEG C needed for greying.Increase refrigerating unit simultaneously, adopt multistage refrigerating unit to make material outlet temperature lower than 350 ~ 400 DEG C.
Embodiment 2: up/down portion of the present invention electrode changes carbon electrode into, the cross section of such electrode is comparatively large, distribution of current in stove can be made comparatively even, but may make input and output material difficulty.Refrigerating unit adopts the multistage type of cooling equally.
