Abstract
The utility model provides a graphitization furnace. The furnace comprises a left graphite particle layer, a right graphite particle layer and a furnace core which is positioned at inner sides of the graphite particle layers, wherein front and rear edges of the inner side of the furnace core are provided with furnace walls, old insulating materials and new insulating materials sequentially from outside to inside; and a resistance material is filled between the new insulating materials at two sides; the old insulating materials are petroleum coke, and the new insulating materials are petroleum coke. The process of graphitizing a raw material can be accelerated because the petroleum coke serving as the insulating material has a better insulating effect, so that the graphitization degree of products can be higher, and the quality can be better. Furthermore, after the petroleum coke serving as the insulating material is used for several times continuously, the petroleum coke can be used as a high-quality side product carburant for export sales, so that the cost can be reduced.
Description
Technical field
The utility model relates to a kind of graphitizing furnace, particularly a kind of graphitizing furnace that adopts refinery coke to make insulation material.
Background technology
Graphitizing furnace is mainly used in the high temperature processing such as graphite powder purification.Its use temperature is up to 2800 ℃.Production efficiency is high, energy saving.At present, the insulation material that adopts in known graphitizing furnace all adopts carbon black, the price of this material is high, granularity is little, the aftertreatment separating difficulty is large and each greying after loss larger, therefore graphited cost is higher.Therefore prior art still has improved necessity.
Summary of the invention
The utility model provides a kind of graphitizing furnace, to solve the technical problem that exists in background technology.
For this reason, a kind of graphitizing furnace of the present utility model, wherein, comprise the graphite granulosa of the left and right sides and the combustion chamber that is positioned at graphite granulosa inboard, the both sides, front and back of described combustion chamber inboard all are disposed with furnace wall, old insulation material and new insulation material from outside to inside, are filled with resistance material between the new insulation material on described both sides.
Described graphitizing furnace, wherein, described old insulation material is refinery coke.
Described graphitizing furnace, wherein, described new insulation material is refinery coke.
After the utility model adopts refinery coke to make insulation material, easy separation, better heat preservation, and price of petroleum coke is low, can do the export trade of high-quality byproduct carburetant after greying, thereby reduce greatly production cost, has reached useful technique effect.

Description of reference numerals
Graphite granulosa-1; Combustion chamber-2; Furnace wall-3; Old insulation material-4; New insulation material-5; Resistance material-6.
Embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and be elaborated by reference to the accompanying drawings.
As shown in Figure 1, graphitizing furnace of the present utility model comprises the graphite granulosa 1 of the left and right sides and the combustion chamber 2 that is positioned at graphite granulosa 1 inboard, the both sides, front and back of combustion chamber 2 inboards all are disposed with furnace wall 3, old insulation material 4 and new insulation material 5 from outside to inside, are filled with resistance material 6 between the new insulation material 5 on described both sides.
The utility model is made the deficiency of insulation material in order to overcome the available technology adopting carbon black, adopt refinery coke as the material of old insulation material 4 and new insulation material 5.Be new insulation material 5 when refinery coke newly is filled into graphitizing furnace, become old insulation material 4 after use for some time.Need constantly to take out old material in use and fill virgin material.
As insulation material, following advantage is arranged with refinery coke:
1, make the insulation material better heat preservation with refinery coke, every stove can be saved power consumption 5%.
2, make insulation material with refinery coke and can accelerate the graphited process of raw material, make the product degree of graphitization higher, better quality.
3, after refinery coke is made several stoves of the continuous use of insulation material, can do the export trade of high quality byproduct carburelant, reduce cost, every stove loss only has 1%, has reduced waste, can increase the economic benefit of enterprise.
4, price of petroleum coke is low: 2000 yuan/tons, and the carbon black price is high: 6000 yuan/tons.
5, to do the insulation material loss large for carbon black, every stove loss about 15%.And be not easy to separate, cost is improved.
6, the greying refinery coke is made insulation material the degree of graphitization of product can be reached more than 90%.
7, every stove power transmission process time can shorten nearly 8 hours, has reduced power consumption, thereby has reduced product cost.
8, technological temperature control can be reduced to 3000 ℃ by 3200 ℃.
Above is illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in protection domain of the present utility model all.
