Description
Technical field
The utility model belongs to a kind of expansion furnace, is specifically related to a kind of Graphene rapid expansion stove.
Background technology
Since Graphene found from 2004, because of the power of its excellence, heat, the performance such as optical, electrical, become rapidly the focus of every profession and trade research and concern.The industrialization of Graphene becomes the emphasis of people's care especially.Prepare graphite oxide by oxidation graft process, and then obtain through thermal expansion reduction the Graphene preparation technology that Graphene is current main flow.But, due to singularity and the novelty of Graphene self, the difficult separation property such as, in oxidising process in severe corrosive, purge process, the lot stability etc. in puffing process.Therefore, the device that the Graphene of also not shaping at present is special.The workshop sections such as synthesis, purifying and drying still can use for reference ripe chemical industry equipment and use after improving, and the continuous swelling stove of powder does not have ready-made experience to use for reference.
At present, most of process furnace market used can be divided into Resistant heating, Infrared Heating and microwave heating according to type of heating.
Resistant heating stove shortcoming is obvious: (1) rate of heating is slow; (2) indirect heating.First furnace tubing, then by the material in radiation heating boiler tube, capacity usage ratio is low; (3) have thermal insulation layer in the middle of boiler tube and body of heater, in heat-processed, accumulation of heat is serious, is unfavorable for being rapidly heated, and thermal shocking is simultaneously comparatively large, and temperature-controlled precision is lower, and cooling rate is slow.Therefore the quick expand continuously of Graphene is not suitable for.
Although infrared heating furnace rate of heating is fast, while heated material, also body of heater and thermal insulation layer heating, capacity usage ratio is low.Although rate of heating is fast, it is more difficult that temperature controls.And cooling rate is also very slow, is not suitable for the quick expand continuously of Graphene.
The microwave that microwave oven is produced by microwave generator will directly be absorbed by material, and in whole heat-processed, only material is heated because absorbing microwave.The miscellaneous parts such as body of heater can not absorb microwave.Therefore capacity usage ratio is high.Existing microwave oven is generally box-type furnace, and microwave field distribution is uneven, and due to structural limitations, charging and rewinding must open fire door, easily produce dust pollution, cannot realize the expand continuously of Graphene.
Summary of the invention
For realizing the quick continuous swelling of Graphene, solve the technical problems such as production efficiency is low, capacity usage ratio is low, the purpose of this utility model is to provide the quick puffing furnace of fast, that capacity usage ratio the is high Graphene of a kind of expanded speed.
For realizing above-mentioned technical purpose, the technical solution of the utility model is:
A kind of Graphene rapid expansion stove, it comprises body of heater, microwave generator; opening for feed, discharge port, protection gas entrance; it is characterized in that there is T-shaped boiler tube in body of heater, T-shaped boiler tube upper end is opening for feed, and on the top being positioned at body of heater; the left end of T-shaped boiler tube is protection gas entrance; and being positioned at outside the left wall of body of heater, T-shaped boiler tube right-hand member is discharge port, and is positioned at outside the right wall of body of heater; be provided with microwave anti-leak cover in body of heater and between T-shaped boiler tube, between microwave anti-leak cover and body of heater, have microwave generator.
Described microwave anti-leak cover is square type Metal shell, prevents microwave leakage.
Described microwave generator respectively has two microwave generators, as the thermal source of expansion of graphene at the upper and lower surface of microwave anti-leak cover.
Technique effect of the present utility model is, utilizes graphite oxide to the strong absorbent of microwave, using microwave as thermal source, direct heating graphite oxide, makes its stripping of expanding, then collects through material-receiving system, carry out the expansion of next batch, every batch only needs tens seconds from the rewinding that feeds intake, expand into.Because all oxidized graphite of microwave produced absorbs, other parts of body of heater do not absorb microwave, therefore can not be heated, and there is not intensification and the temperature-fall period of body of heater, energy utilization efficiency is high.The utility model has structure uniqueness, capacity usage ratio is high, production efficiency is high, long service life, simple to operate, level of automation advantages of higher.
Accompanying drawing explanation
