Description
Technical field
The utility model relates to graphite and manufactures mechanical field, is exactly graphite volume, sheet material second heat treatment device specifically.
Background technology
At present, the graphite volume that China produces, sheet material are by expansible black lead after more than 950 DEG C high-temperature expansions, form by evenly laying repeatedly calendering.What its production technique adopted is disposable thermal process, and it mainly also exists: product sulphur content is higher, and product thermal weight loss rate under 650 DEG C of high temperature reaches 15-20%, has had a strong impact on graphite volume, the product performance of sheet material and service efficiency.Therefore, be necessary to make further improvements it.
Summary of the invention
The utility model just can effectively overcome above-mentioned technical disadvantages, there is provided and have that design science, structure are simple, safe ready, significantly reduce sulphur content in product, improve thermal weight loss, strengthen the graphite of the features such as its product performance volume, sheet material second heat treatment device, it is widely used in the upgrading of graphite volume, lumber producing operations line, is the ideal device that high quality manufactures graphite volume, sheet material.
Technical purpose of the present utility model is achieved in that graphite volume, sheet material second heat treatment device, is made up of puffing furnace, topping roll, bottom roll, laying plate, extractor fan, heating unit, inflation mechanism.Puffing furnace is connected with laying plate, and topping roll and bottom roll lay respectively at lays plate upper and lower, and extractor fan is positioned to be laid above plate, and heating unit is positioned to be laid below plate, and inflation mechanism is positioned at lays plate upper and lower.
Described inflation mechanism has two covers;
Described topping roll and bottom roll symmetry are installed;
Described topping roll has how many, and bottom roll symmetrical with it just has how many;
Described extractor fan and heating unit symmetry are installed;
Described extractor fan and heating unit are arranged between right-to-left second topping roll, bottom roll and the 3rd topping roll, bottom roll;
Principle of work of the present utility model is: be add two complete equipments on conventional graphite volume, sheet material manufacturing machine, that is: extractor fan, heating unit, just reach reduce sulphur content in graphite, improve high temperature under thermal weight loss, increase the object of its product performance and service efficiency.Graphite volume, sheet material are in the fabrication process, through the Graphite Powder 99 temperatures as high 900-950 DEG C that puffing furnace first time thermal treatment is expanded, by lay plate enter second topping roll and bottom roll roll time, graphite shaping for the first time is now rolled up, the temperature of sheet material has been reduced to about 50 DEG C, cause the sulphur content rising of finished product volume, sheet material, thermal weight loss rate is up to 15-20%.After adding this device, carry out second time thermal treatment, just thoroughly solve above-mentioned two large technical barriers, its temperature is made to rapidly increase to 900-1000 DEG C, make fully not expanded graphite raw material expanded again, be aided with exhausting, carry out rare gas element air displacement, thus sulphur content in reduction graphite, thermal weight loss rate under raising high temperature.
The beneficial effects of the utility model are: 1, considerably reduce sulphur content.Production practice prove, the sulphur content decline 400PPM in the graphite volume made through second heat treatment, sheet material finished product; 2, improve the thermal weight loss under high temperature.Graphite volume, be about 15-20% through once heat treated sheet forming thermal weight loss under 650 DEG C of high temperature in board making process, the sheet forming thermal weight loss under 650 DEG C of high temperature through second heat treatment brings up to 8-10%.

Embodiment
By the following examples, the utility model is described in more detail, as long as but within the scope of main idea of the present utility model, be not limited in following examples.
Graphite volume, sheet material second heat treatment device, be made up of puffing furnace (1), topping roll (2), bottom roll (3), laying plate (4), extractor fan (5), heating unit (6), inflation mechanism (7).Puffing furnace (1) is connected with laying plate (4), topping roll (2) and bottom roll (3) lay respectively at lays plate (4) upper and lower, extractor fan (5) is positioned at lays plate (4) top, heating unit (6) is positioned at lays plate (4) below, and inflation mechanism (7) is positioned at lays plate upper and lower.
During work: through puffing furnace (1) first time heat treated graphite piece, sheet material temperatures as high 900-950 DEG C, topping roll (2) is entered by laying plate (4), bottom roll (3) calendering program, by second topping roll (2), during bottom roll (3) calendering, graphite volume shaping for the first time, the temperature of sheet material is reduced to about 50 DEG C, when the second cover heating unit (6), its graphite shaping is for the first time rolled up, sheet material temperature rises to 950-1000 DEG C rapidly, raw material fully not expanded in graphite is able to expanded again, extractor fan (5) exhausting, discharge waste heat, rare gas element is released in inflation mechanism (7), as: ammonia, carry out air displacement, effectively reduce sulphur content in graphite, avoid graphite to roll up simultaneously, sheet material is not oxidized, and then through follow-up upper, bottom roll calendering forms finished product.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit protection domain of the present utility model with this; therefore: all equivalence changes done according to shape of the present utility model, structure, principle, all should be covered by within protection domain of the present utility model.
