Background technique
Graphite (graphite) is a kind of crystalline carbon.Hexagonal crystal system, for iron mass colour to Dark grey.2.25 gram/li of density
Rice 3, hardness 1.5,3652 DEG C of molten point, 4827 DEG C of boiling point.Matter is soft, there is soapy feeling, electrically conductive.Chemical property torpescence, it is corrosion-resistant,
It is not easy to react with acid, alkali etc..Reinforce heat in air or oxygen, incendivity simultaneously generates carbon dioxide.Strong oxidizer can be by its oxygen
It is melted into organic acid.As antifriction additive andLubriation material, production crucible, electrode, dry cell,Pencil-lead.High purity graphite can be in core
Make neutron on reactorModerator.It is commonly referred to as carbon or blacklead, because being erroneously interpreted as lead in the past, but produces graphite at present
Method is all more complicated and at high cost, low efficiency.
Therefore, how a kind of technique of easy to operate, at low cost, high-efficient production graphite is provided, is knack of the present invention
The technical issues of solution.
Summary of the invention
In view of the above drawbacks of the prior art and problem, it is an object of the present invention to provide a kind of easy to operate, at low cost, effects
The technique of the high production graphite of rate.
In order to achieve the above object, the present invention provides the following technical solutions
A kind of technique producing graphite, equipment include can-type calcine furnace, kibbler roll, thunder illiteracy pulverizer, vibrating screen, head
It first passes through transporter and transport and material is transferred in kibbler roll by conveyer belt being crushed by material, wherein
The material is petroleum coke and pitch coke, is calcined after broken by can-type calcine furnace, and calcined material is expected after entering forging
In storehouse, wherein the material calcined by can-type calcine furnace is in needle coke, and the material of needle coke is entered thunder and covers powder
It is crushed again in broken machine, broken rear material is sieved, and the vibrating screen that is sieved through is sieved, and is generated after screening
Material carries out feed bin, and the material screened out carries out milling operation again by flour mill；
It mixes, mixes secondly, the material generated after screening is transported in kneading pot by electronic burden charging carriage
The material of generation is roasted again after entering press, and the material after roasting is impregnated, and after baking is carried out after dipping, secondary
It is impregnated after roasting, is roasted three times after being impregnated again, graphitizing furnace is carried out after roasting three times, into graphitizing furnace
It is machined out, common graphite electrode, impregnated graphite electrode and high efficiency graphite electrode is generated by machining.
Further, pitch is added in the kneading pot to be mixed with material.
Further, the pitch is purified by cleaning equipment.
In terms of existing technologies, the present invention includes can-type calcine furnace, kibbler roll, Lei Meng due to equipment to the present invention
Pulverizer, vibrating screen, by being crushed twice, so that it is guaranteed that petroleum coke and pitch coke are more careful, so that produce
Final product quality is more good, also, the technological operation is convenient, and safety non-pollution realizes the continuous industry metaplasia of graphite products
It produces, improves product quality and yield.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the process flow chart of present invention production graphite.
Specific embodiment
Below in conjunction with attached drawing of the invention, technical solution of the present invention is clearly and completely described, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this hair
The range of bright protection.
As shown in Figure 1, a kind of technique for producing graphite disclosed by the invention, equipment include can-type calcine furnace, roll crushing
Machine, thunder cover pulverizer, vibrating screen, transport by material by transporter first and material is transferred to roll-type by conveyer belt
It being crushed in crusher, wherein the material is petroleum coke and pitch coke, is calcined after broken by can-type calcine furnace,
Calcined material enters after forging in feed bin, wherein the material calcined by can-type calcine furnace is in needle coke, by needle coke
The material enter thunder and cover in pulverizer and be crushed again, it is broken after material sieved, it is described to be sieved through vibration
It is sieved, the material generated after screening carries out feed bin, and the material screened out carries out milling operation again by flour mill；
It mixes, mixes secondly, the material generated after screening is transported in kneading pot by electronic burden charging carriage
The material of generation is roasted again after entering press, and the material after roasting is impregnated, and after baking is carried out after dipping, secondary
It is impregnated after roasting, is roasted three times after being impregnated again, graphitizing furnace is carried out after roasting three times, into graphitizing furnace
It is machined out, common graphite electrode, impregnated graphite electrode and high efficiency graphite electrode is generated by machining.
Through the above it is not difficult to find that since equipment includes can-type calcine furnace, kibbler roll, thunder illiteracy pulverizer, vibration
Dynamic sieve, by being crushed twice, so that it is guaranteed that petroleum coke and pitch coke are more careful, so that the final product quality produced is more
What is added is good, also, the technological operation is convenient, and safety non-pollution realizes the continuous industrial production of graphite products, improves production
Quality and yield.
In addition, it is necessary to illustrate, pitch is added in present embodiment, in the kneading pot and is mixed with material, institute
Pitch is stated to be purified by cleaning equipment.
