Abstract
The utility model relates to a multi-layer porous filter element structure inner cavity used for graphene expansion. The multi-layer porous filter element structure inner cavity comprises a cavity cover (1), a cavity opening (2) and a cavity body (3), wherein the cavity opening (2) is formed in the front end of the cavity body (3) and is sealed by the cavity cover (1), and the cavity body (3) is of a multi-layer porous structure. Due to the porous structure, micro-nano graphene powder is limited in the cavity body, while introduced and generated gas can overflow, so that the graphene powder can be prevented from polluting a pipeline and the environment along with the flowing of gas. The inner cavity is beneficial to collecting expanded samples, is safe to use, high-temperature-resistant, high-pressure-resistant and corrosion-resistant, and also improves the preparation and expansion efficiency of graphene.
Description
Affiliated technical field
The utility model relates to the filter cartridge construction inner chamber prepared in Graphene required a kind of mechanical part, especially Graphene expansion process.
Background technology
2004, Graphene was found at first by Andre professor Geim of University of Manchester leader's research group
.graphene has excellent electricity, optics, calorifics and mechanical property, and has high stability, has caused the great interest of science and industry member.Graphene has application extremely widely in a plurality of fields, prepare the microelectronic devices such as high performance field effect transistors as can be used for, the photoelectric devices such as solar cell, photodetector etc.; High specific surface area (the 2630m based on it
2/ g), and outstanding heat, chemical stability, can be applied to energy storage device, as lithium ion battery, ultracapacitor etc.
In the preparation method of many Graphenes, by graphite oxidation, and the graphene powder (gram that obtains of the reduction of expanding, the kilogram or tonne), can, for all kinds of photoelectricity, energy storage device and matrix material, be considered to most possibly take the lead in realizing the graphene preparation method of industrialization.Yet, in the process of preparation in macroscopic quantity graphene oxide, do not have the expansion reduction apparatus that a kind of specialty quantizes for graphene oxide production.And answer the demand of future market to Graphene and related compound material, production department and company not only will keep its product quality, also must improve its production schedule, in other words simultaneously, each link on production line, all can affect the lifting of preparation speed and output.Because the market competition between the same industry and close industry is quite fierce now, try to be the first and capture market if can not improve the process for processing speed on production line, will be eliminated by social cut-throat competition.Past or more existing expansions, annealing device, as well formula resistance furnace, pit type annealing furnace, box-type furnace, tube furnace etc., can not the fine requirement met rapidly in the Graphene expansion procedure.The inner chamber material that their are equipped with mainly is comprised of stainless steel or silica tube, sealing and do not have ventilation property.During the logical protection of inner chamber gas lift temperature, the additional gas produced that expands causes the interior pressure of body of heater excessive because not flowing out in time, thereby has brought potential safety hazard.In addition, the fixed furnace binding with inner chamber is not easy to graphene powder is collected yet, and has reduced the efficiency of process for processing.And, graphene powder can be with Diffusion of gas stream in expansion process pipeline and other parts of contaminated equipment, life-span, stability and the security meeting of whole plant caused damage.The graphene powder of micro-nano magnitude also can cause certain influence to HUMAN HEALTH.The unfavorable factor of these existence, stress fast with industry now, the manufacturing philosophies such as efficient, high yield, environmental protection run in the opposite direction.
Summary of the invention
The problems such as existing Graphene expansion process yields poorly in order to overcome, poor stability, contaminated equipment and environment, the poroid filter cartridge construction inner chamber of multilayer that the utility model provides a kind of Graphene to expand, can optionally be limited in the graphene powder of the micro-nano order of magnitude in cavity, pass into or expellant gas can overflow, improved output and security, to human body also without harm.
For reaching above purpose, the utility model solves the technical scheme that its technical problem adopts and is: a kind of poroid filter cartridge construction inner chamber of multilayer expanded for Graphene, comprise chamber lid, accent and cavity, and chamber lid sealing for accent, cavity is cavernous structure.
Cavity described in the utility model is the cavernous structure more than at least two layers; The filter core aperture of described cavernous structure is 0.01～5 μ m; Described cavity adopts high temperature resistant, corrosion-resistant material, and filter core adopts stainless material; Described cavity geometry is cylinder; Described cavity is right cylinder, chamber cap seal mouth for an end, and the other end designs for dome head.
After adopting above technical scheme, the beneficial effects of the utility model are: can in the Graphene expansion process, optionally be limited in the graphene powder of the micro-nano order of magnitude in cavity, prevent that graphene powder from polluting pipeline and environment with gas flow, and the gas that passes into and produce can overflow, in chamber, pressure keeps stable.In addition, also be conducive to the to expand collection of rear sample of this inner chamber, used safety, high temperature high voltage resistant, anticorrosive, also can improve preparation and the expansion efficiency of Graphene.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, a kind of poroid filter cartridge construction inner chamber of multilayer expanded for Graphene of the utility model, comprise chamber lid 1, accent 2 and cavity 3, accent 2 use chamber lid 1 sealings, and cavity 3 is for being cavernous structure.
The aperture of cavernous structure described in the utility model reaches 1 μ m, just can be limited in the graphene powder of micro-nano magnitude in cavity, and the gas that passes into and produce can overflow.
The utility model embodiment: at first will need the graphene oxide sample expanded to send in chamber from accent, and then close in Gai，Wang chamber, chamber and fill protection or reactant gases, heating heats up.The chamber cover generally is placed on the non-heating zone of body of heater.In whole expansion process, the protection gas be filled with and the gas produced that expands can overflow from the filter core cavity, and the graphene powder of the micro-nano order of magnitude after expanding optionally is limited in cavity, has prevented that powder from entering pipeline, pollutes and damage equipment.In whole process, the protection gas in chamber forms running balance, maintains pressure stable.Because powder is stoped by cavity and can not spread, the tail gas of discharge, through special processing, yet can not produce injury or production environment is polluted human body, makes expansion process safe and environmentally friendly.Expand after end, from this filter core inner chamber, can collect easily graphene powder.
