The purity promotion of graphite has the upper limit, but whole flow process is easy to operate, technical maturity, usually as pretreatment to graphite raw ore into
Row preliminary purification.
Alkali acid system, hydrogen fluoride, chlorinating roasting belong to chemical method purification.Alkali acid system purifies graphite technology complexity, energy
Consumption is high, and purification efficiency is low, equipment seriously corroded, has certain influence to environment.The fixed carbon content energy of the graphite of hydrogen fluoride purification
Enough reach 99.9% or more, although equipment is simple, easy to operate, cost is relatively low, hydrofluoric acid corrosivity is strong, has one to human body
Fixed harm must carry out stringent monitoring to safety and waste water in production process to environment there are larger pollution.Chlorinating roasting mentions
Pure graphite purification efficiency and the rate of recovery are high, but process conditions are unstable, purifying higher cost, tail gas is difficult, be easy to cause sky
Gas is seriously polluted etc..In addition, chlorine has the shortcomings that certain toxicity, severe corrosion to equipment, poor controllability limit chloridising roasting
The popularization and application of method.
High temperature method purification equipment used is acheson furnace and periodic vacuum induction furnace.It comprises the concrete steps that and sets graphite
In in a graphite crucible, graphite crucible is then heated to 2700~3000 DEG C, graphite is heated by graphite crucible.But mesh
Preceding there is also following three problems: one, heating cycle is long, and acheson furnace room temperature from beginning to warm up to dropping to generally requires 8~10
It, electric induction furnace needs 2~3 days；Two, acheson furnace and electric induction furnace are indirect heatings, are not to directly heat graphite composite powder,
It heats graphite crucible and consumes a large amount of energy；Three, acheson furnace and electric induction furnace are all unable to continuous production.

The utility model has the beneficial effects that graphite vacuumizes feeding warehouse when being placed on feeding warehouse, the oxygen of graphite is avoided
Change；Graphite passes through laser heating zone during the falling process, is heated, is made in graphite to the rapid laser of graphite by laser galvanometer
Impurity gasification, is passed through protective gas into barrel by air inlet pipe, the impurity of gasification is discharged protective gas by escape pipe, finally
Graphite after being purified in discharging bin；Graphite after laser heating passes through the cooling water temperature in collet by cooling area；
The present apparatus continuously can carry out high temperature purification to graphite, and the period is short, production cost is low.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged drawing of barrel in Fig. 1.
Specific embodiment
As shown in Figure 1, the utility model provides a kind of continuous type graphite high temperature purification device, including the barrel being vertically arranged
1,1 outer wall of barrel is equipped with collet 2, and 2 lower part of collet is equipped with cooling water inlet 2a, 2 top of collet is equipped with cooling water outlet 2b；Barrel
1 top is connected with feeding warehouse 3, and feed inlet 3a and bleeding point 3b is equipped at the top of feeding warehouse 3, and feed inlet 3a is equipped with the first inlet valve 4,
Bleeding point 3b is equipped with the second inlet valve 5 for connecting vaccum-pumping equipment, 3 bottom of feeding warehouse；As shown in connection with fig. 2, the barrel 1 by
Up to lower comprising buffer area 1a, laser heating zone 1b and cooling area；Preferably, cooling area from top to bottom includes level-one cooling
Area 1c and second level cooling area 1d；The internal diameter of barrel level-one cooling area 1c is greater than the internal diameter of barrel second level cooling area 1d, level-one cooling
The area lower part 1c can be set to funnel-form and be connected with second level cooling area 1d phase；Buffer area 1a inner wall is symmetrically arranged with two pieces of inclined plates directed downwardly
6, blanking port is formed between the bottom edge of two pieces of inclined plates 6, buffer area 1a upper portion side wall is equipped with the air inlet pipe 7 for being pierced by collet 2；Laser adds
Hot-zone 1b side wall is equipped with laser galvanometer 8, and laser galvanometer 8 is set to the two sides of laser heating zone 1b, and every side is from top to bottom distributed with
One group of laser galvanometer；Cooling area upper portion side wall is equipped with the escape pipe 9 for being pierced by collet 2, and cooling area bottom is connected with discharging bin 10.
In use, being first turned on the first inlet valve 4, the second inlet valve 5 is closed, it is built-in to feeding warehouse 3 by feed inlet 3a
Enter graphite powder, is then vacuumized by bleeding point 3b connection vaccum-pumping equipment, stopping when the present embodiment reaches 500Pa pressure
It vacuumizes, vacuumizing to feeding warehouse 3 can prevent graphite powder to be oxidized；It is passed through cooling water into collet 2 by cooling water inlet 2a,
Meanwhile protective gas is passed through into barrel 1 by air inlet pipe 7, the present embodiment protective gas uses argon gas, can also be used other lazy
Property gas；Then the second inlet valve 5 is opened, graphite powder enters the buffer area 1a of barrel, and graphite powder is formed by two pieces of inclined plates 6
Blanking port rallentando falls on down laser heating zone 1b, and laser galvanometer 8 heats the graphite powder passed through, even if moment stone
Ink powder is heated to 2700 DEG C, and the impurity in graphite powder gasifies at high temperature, and impurity is discharged protective gas by escape pipe 9 expects
The purification to graphite powder is realized in storehouse；Graphite powder after purification falls into level-one cooling area 1c first,
Since level-one cooling area 1c internal diameter is larger, graphite powder is seldom fallen on during descending slowly and lightly in the 1c of level-one cooling area
Wall, therefore it is essentially natural cooling in level-one cooling area 1c graphite powder, graphite powder then descends slowly and lightly to second level cooling area 1d, second level drop
Warm area 1d is since internal diameter is smaller, so graphite powder can largely fall in the inner wall of second level cooling area 1d, realizes water cooling by collet 2
But；Graphite powder after cooling falls into discharging bin 10, and discharging bin 10 is collected graphite powder.
