The utility model discloses a raw material preheating device. According to the utility model, waste heat can be effectively used. The raw material preheating device comprises an electric-arc furnace heat collection cover and a preheating furnace, wherein the electric-arc furnace heat collection cover comprises a funnel-shaped heat collecting cavity; the large end of the heat collecting cavity is downward, and the small end of the heat collecting cavity is communicated with a main delivery pipeline; the main delivery pipeline is connected with the heat supply opening of the preheating furnace; a dust remover connected with the preheating furnace is arranged above the preheating furnace; the preheating furnace is also connected with a discharge pipe; a control valve is arranged on the discharge pipe. Through the adoption of the preheating device, the waste heat can be recycled; the recycled waste heat can be used for preheating vanadium product raw materials; the raw materials being subjected to preheating reach a relatively high technically required temperature so as to shorten smelting period and greatly lower the electrical energy loss.

Description

Raw material preheating device
Technical field
The utility model relates to a kind of preheating furnace device before entering stove and smelt for vanadium goods.
Background technology
Electric furnace smelting vanadium goods are in current vanadium goods alloy smelting technology, a kind of smelting mode generally adopting, be widely used in the fields such as metallurgy industry vanadium goods alloy smelting, it is a kind of technology of smelting vanadium goods by electrical heating, as iron and steel metallurgical industry, electric furnace smelting vanadium goods are also widely used in the processing of vanadium goods alloy.
Existing tradition is smelted vanadium goods electric furnace, that a kind of vanadium goods that Panzhihua vanadium titanium industrial zone generally adopts are smelted mode, in use, because need consuming a large amount of electric energy, electric furnace smelting realizes vanadium alloy heating raw materials to the critical point of temperature required (1300 ℃--1600 ℃), therefore power consumption is huge, and at present garden Nei Ge enterprise electric furnace through adding thermogenetic waste heat flue gas and the slag waste heat that produces of slagging tap (300 ℃--600 ℃) does not all recycle, cause waste heat waste and the excessive environment that affects of flue gas, caused vanadium goods smelting cycle long, high and the environmental pollution of energy consumption.
Utility model content
The technical problem that the utility model solves is to provide a kind of raw material preheating device that waste heat can be utilized.
The utility model solves the technical scheme that its technical problem adopts: raw material preheating device, comprise electric arc furnaces collector mat and preheating furnace, electric arc furnaces collector mat comprises infundibulate heat collector cavity, the large end of heat collector cavity arranges down, the small end of heat collector cavity is communicated with main delivery pipe, and main delivery pipe is connected with the heat supply mouth of preheating furnace, and preheating furnace top is provided with the deduster being connected with preheating furnace, on preheating furnace, be also connected with tremie pipe, on tremie pipe, be provided with control valve.
Further: also comprise pit, the top of pit is provided with pit collector mat, pit collector mat is communicated with main transfer passage by arm.
Further: the heat supply mouth place of preheating furnace is provided with blower fan.
The beneficial effects of the utility model are: the waste heat producing when electric arc furnaces and pit can be used reclaims, waste heat after recovery can be used for vanadium goods raw material to carry out preheating, raw material through preheating reaches compared with high technology demand temperature, thereby shortened smelting cycle, has also significantly reduced the loss of electric energy.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of raw material preheating device;
In figure, be labeled as: preheating furnace 1, tremie pipe 2, deduster 3, blower fan 4, main delivery pipe 5, heat collector cavity 6, electric arc furnaces collector mat 7, electric arc furnaces 8, ladle 9, pit collector mat 10, arm 11, pit 12.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, raw material preheating device of the present utility model, comprise electric arc furnaces collector mat 7 and preheating furnace 1, electric arc furnaces collector mat 7 comprises infundibulate heat collector cavity 6, the large end of heat collector cavity arranges down, and the small end of heat collector cavity is communicated with main delivery pipe 5, and main delivery pipe 5 is connected with the heat supply mouth of preheating furnace 1, preheating furnace top is provided with the deduster 3 being connected with preheating furnace 1, is also connected with tremie pipe 2 on preheating furnace.
During use, electric arc furnaces 8 and ladle 9 are placed in to electric arc furnaces collector mat 7 belows, the large end of heat collector cavity 6 is towards electric arc furnaces 8.Heat electric arc furnaces 8 in use being discharged by electric arc furnaces collector mat 7 reclaims, and this part heat enters in preheating furnace 1 by main delivery pipe 5.In preheating furnace 1, taken up raw material, raw material can enter in preheating furnace by tremie pipe 2.Dust in preheating furnace can be removed by deduster 3.Utilize the waste heat that electric arc furnaces produces can be to heating raw materials, through the raw material of preheating, can reach compared with high technology demand temperature, thereby shortened smelting cycle and significantly reduced the loss of electric energy.And, waste heat flue gas is re-used and also helps environmental protection.
Itself also can produce high-temperature flue gas the slag of pouring out from electric arc furnaces 8, if this part waste heat is used, can further improve waste heat recovery rate, is conducive to further save the energy.For this reason, on the basis of the above, also comprise pit 12, the top of pit 12 is provided with pit collector mat 10, and pit collector mat 10 is communicated with main transfer passage 5 by arm 11.The high-temperature flue gas of pit 12 interior generations can enter main transfer passage 5 by pit collector mat 10 and arm 11, enters after main transfer passage 5, and this part flue gas can enter preheating furnace 1 along main transfer passage 5, and then heats for the raw material in preheating furnace 1.
In order to impel high-temperature flue gas to enter comparatively smoothly in preheating furnace 1, on the basis of the above, the heat supply mouth place of preheating furnace 1 is provided with blower fan 4.By blower fan 4, the high-temperature flue gas in main transfer passage 5 can be drawn in preheating furnace 1.
