The electro-corundum of the different cultivars such as shape corundum.
Generally at 2100 DEG C, smelting time is generally 4 hours electric smelting temperature in electric smelter, and the good melt of electric smelting, which will pour into, to be connect
Bao Zhong commonly connects and is surrounded by that water is cooling and natural cooling (dry and cold but) two ways, and water cooling mode easily goes out safety accident, most
Enterprise no longer selects.Currently used is natural cooling (dry and cold but).Frit drops to room temperature from 2000 DEG C and has distributed a large amount of heat
Can, it does not utilize, wastes.
Utility model content
In order to overcome above-mentioned the problems of the prior art, the present invention provides a kind of simple processes, and equipment cost is lower, and
The device using electric smelting block exhaust-heat heating electric smelting raw material of easily operated installation.
In order to achieve the above objectives, using following technical scheme.
A kind of electric smelting raw material heating apparatus using electric smelting block waste heat, including carrying high temperature frit connect packet, hopper and
Raw material thermal insulation barn further includes the charging device that feed powder is poured into raw material thermal insulation barn and the support frame for hopper, institute
State support frame be crossed on it is described meet the side of wrapping, the upper surface hollow out of support frame as described above, the charging device includes column, elevator
Structure, hydraulic clamp structure and turnover mechanism, the elevating mechanism are moved up and down along the column, hydraulic clamp structure with
And turnover mechanism is fixed on elevating mechanism.The turnover mechanism is to clamp and overturn that raw material powder is poured into raw material heat preservation by hopper
In storehouse.
The hopper is equipped with the step for clamping.
The hopper is 1.5 meters of outer diameter, and internal diameter is 0.7 meter, is highly 1.4 meters of hydrostatic column.
The raw material thermal insulation barn is the external bin device attached with thermal insulation material.
Support frame as described above is that upper surface is rectangle, is equipped with through-hole among it, it is logical that the lower step of the hopper may pass through this
Hole.
The bottom inside of the hopper raises upward, and outside is recessed inwardly to form a groove.Heat-absorbent surface is increased in this way
Product absorbs the device of thermal energy convenient for interior charge powder.
Positive beneficial effect: the heating apparatus is by being used for tapping temperature up to the heat in 2000 DEG C of electric smelting blocks coolings
Raw material is heated, in the raw material investment electric furnace that will be heated (the alumina powder temperature of heating is up to 90 DEG C), which improves oxygen
The initial temperature for changing aluminium powder, was shorten to 228 minutes by original the room temperature furnace charge electric smelting time 240 minutes, and a furnace can save 60KWh electricity
Amount, produces the enterprise calculation (1 2 tons of furnace) of 30,000 tons of frits per year by one by 33 yuan of power cost saving, can save within 1 year 900000 KWh electricity, section
About 49.5 ten thousand yuan of the electricity charge improve economic benefit for enterprise.
