Abstract
The invention discloses a vertical type electric heating graphite expansion furnace, and relates to an expansion furnace for graphite paper production. The expansion furnace comprises a furnace body, a heating device and a graphite expansion device, wherein the furnace body is a vertical type cylindrical barrel and consists of a shell as well as an insulating cotton layer, an insulating brick layer, a heating device and an electrode material expansion tube arranged inside the shell; a cavity of the electrode material expansion tube is a graphite expansion channel (7); the electric heating device is a U-shaped silicon-carbon rod or a silicon-molybdenum rod. The expansion furnace has the beneficial effects that due to adoption of electric heating, the expansion furnace is clean and sanitary, and no pollution is caused to high-purity graphite. The temperature can be rapidly increased and the expansion temperature can be easily controlled because of the electric heating. The expansion furnace is simpler in structure when being compared with a fuel oil/gas expansion furnace, the construction cost is low, the service life is long, the use expense is low, and the production cost can be lowered. As graphite uniformly and dispersedly falls from the top of the vertical expansion furnace, and is uniformly heated and expanded, high-quality ultra-thin soft graphite paper can be produced.
Description
Technical field:
The present invention relates to machining graphite technical equipment, the graphite expansion stove of particularly producing for graphite paper.
Background technology:
In flexible graphite paper production process, need first high purity graphite phosphorus sheet to be expanded.In prior art, device for graphite expansion is that high-temperature expansion stove mostly is Horizontal type, and all adopt oil liquefied gas or diesel heating, the defect of this expansion furnace is, graphite expansion process, fuel combustion meeting produces a large amount of sulfurous gass and is attached on graphite worm, and this just causes graphite worm sulfur-containing impurities greatly to improve, and graphite paper sulfur-containing impurities will greatly affect quality and the use properties of graphite paper.Again, horizontal expander stove, graphite be level pass through expansion furnace furnace chamber, because of gravitate, its density will be upper and lower uneven during by tube chamber for graphite, this will affect the homogeneity of graphite expansion, and directly has influence on the thickness quality of produced flexible graphite paper.
Summary of the invention:
The present invention's object is to provide a kind of vertical electric heating graphite expansion stove, and simple in structure, quick heating, is easy to control, and cost is low, long service life, and graphite worm expands full and uniform.
Technical scheme of the present invention: a kind of vertical electric heating graphite expansion stove, comprises body of heater, heating unit, expansion gear.Described graphite expansion device 1 be vertical electrical heating expansion furnace 1 ', be followed successively by insulating cotton layer 3, insulating brick-layer 4, electrothermal tube 5, electrode materials expansion pipe 6 forms by housing 2, in it, electrode materials expansion pipe tube chamber is graphite expansion passage 7, expansion furnace top is provided with charging opening 9, and bottom is provided with discharge port 10.
Described electric heater unit is U-shaped globars or U-shaped Si-Mo rod, and globars or Si-Mo rod connect power supply.Described electrode materials expansion pipe is graphite electrode material expansion pipe.
The beneficial effect that the present invention produces:
Adopt electrically heated sanitation and hygiene, can high purity graphite not produced and be polluted.Electrically heated quick heating, expansion temperature are easily controlled.Expansion furnace is simple in structure, and cost is low, long service life.Electrically heated than the swollen heating cost of use of fuel-firing gas-firing at the bottom of, can reduce production costs.Expansion furnace is designed to vertical, and graphite, by the dispersed whereabouts of the furnace chamber that expands, is heated, expands evenly, is conducive to produce high quality, ultrathin flexible graphite paper.
Brief description of the drawings:
Accompanying drawing 1 front view of the present invention
Embodiment:
Figure of description has provided a kind of embodiment of the present invention.Below in conjunction with accompanying drawing, the present invention's structure is described further.
As shown in Figure 1, a kind of vertical electric heating graphite expansion stove, comprises body of heater, heating unit, graphite expansion device in the present invention.Body of heater is vertical type cylinder cylindrical shell, set gradually insulating cotton layer 3, insulating brick-layer 4, electric heater unit 5, electrode materials expansion pipe 6 forms by housing 2, in it, electrode materials expansion pipe tube chamber is graphite expansion passage 7, and body of heater top is provided with charging opening 9, and bottom is provided with discharge port 10.
Described electric heater unit is U-shaped globars or U-shaped Si-Mo rod, and globars or Si-Mo rod connect power supply.Described electrode materials expansion pipe is graphite electrode material expansion pipe.
Its lower expansion tube cavity top of body of heater top feeding mouth is provided with tapered cap 8, and tapered cap is located on endoluminal stent 13.
Graphite expansion process: high-purity acidifying scale graphite is carried by auger 10, enter in expansion furnace expansion tube cavity through body of heater its top feed mouth 9, graphite material is dispersed through the cone cap 8 of being located on support 13, in expansion tube cavity, evenly fall, meeting 900 ° of high volumes will rapid, fiercely expand, expansion reaches hundreds of times, and after expanding, quality is soft, and is drawn as strip graphite worm.Graphite worm declines and enters desulfurizing device by discharge port 11 through pipeline 12.
