Abstract
The utility model discloses a novel vertical type electrical heating graphite expansion furnace, and relates to an expansion furnace used 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 cylinder body comprising a casing, as well as a heat insulating cotton layer, a heat insulating brick layer, a heating device and an electrode material expansion pipe all arranged in sequence in the casing; the cavity of the electrode material expansion pipe is a graphite expansion passageway 7; the electrical heating device is a U-shaped silicon carbon rod or a silicon molybdenum rod. The expansion furnace has the benefits that through adopting electrical heating, the expansion furnace is clean and hygienic, and is prevented from contaminating high-purity graphite; the electrical heating is fast in temperature increment, and the expansion temperature is easy to control; compared with fuel oil-fuel gas expansion furnaces, the expansion furnace is simple in structure, low in furnace-building cost, long in service life and low in usage cost, and can reduce the production cost; according to the vertical type furnace, the graphite falls and disperses uniformly form the top of the furnace, and is subjected to uniform heating and expansion, so that the production of graphite paper which is high in quality, ultrathin and flexible is facilitated.
Description
Technical field:
The utility model 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 object of the utility model is to provide a kind of novel vertical electrically heated graphite expansion furnace, simple in structure, and quick heating is easy to control, and cost is low, long service life, and graphite worm expands full and uniform.
The technical solution of the utility model: novel vertical electrically heated graphite expansion furnace, comprises body of heater, heating unit, graphite expansion device 1.Body of heater is vertical type cylinder cylindrical shell, set gradually 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, and body of heater top is provided with charging opening 9, and bottom is provided with discharge port 10.
Described electrothermal tube 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 utility model 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 the utility model front view
Embodiment:
Figure of description has provided a kind of embodiment of the present utility model.Below in conjunction with accompanying drawing, the structure of the utility model is described further.
As shown in Figure 1, novel vertical electrically heated graphite expansion furnace, comprises body of heater, heating unit, graphite expansion device 1 to the utility model.Body of heater is vertical type cylinder cylindrical shell, set gradually 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, and body of heater top is provided with charging opening 9, and bottom is provided with discharge port 10.
Described electrothermal tube 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 11, 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 10 through pipeline 12.
