Description
Technical field
The present invention or utility model are related to a kind of Medical constant-temperature storage device with fire-proof function, and the storage device is main
Article such as drug for needing constant temperature to store in medical space etc. or bioactive substance such as biological detection sample etc., can
Maintain the temperature in storage device constant for a long time, from the variation and influence of ambient temperature, to guarantee to store article
Matter does not change, and storage and long-distance transportation etc. suitable for medical article are provided simultaneously with fire-proof function.
Background technique
Medical article such as drug, bioactive substance (biological detection sample etc.) needs depositing in specific temperature all the time
It can be played by, which saving under the conditions of storage, should effect, but go bad because ambient temperature variation often will lead to above-mentioned material
Failure, and then its using effect is influenced, or even poison.And current storing mode relies primarily on thermostatic chamber and is stored, i.e., it is logical
Crossing the temperature control equipments such as air-conditioning makes interior in opposite temperature constant state, but this mode is dependent on the large-scale temperature adjusting such as air-conditioning
Equipment cost is higher, and in the case where lacking above-mentioned large-scale temperature control equipment and supporting, when in face of medical article road farther out
Transhipment transport and electric power facility not perfect situation when, the medical article for needing constant temperature to store can obviously rise in way risk, and
Transported by the haulage vehicle with temperature control equipment, higher cost, and when have can not be using the feelings of above-mentioned vehicle and equipment
Condition occurs.It can be seen that designing a kind of storage device for getting rid of the large-scale temperature control device that places one's entire reliance upon at present can just solve the above problems,
Need one kind the maintenance of longer time can store the temperature of article in a perseverance under conditions of disengaging large-scale temperature control device
Determine the device in temperature range.
Summary of the invention
The purpose of the present invention is intended to provide a kind of independent of the remote constant temperature transmission medical article of large-scale temperature control device energy
Storage device, to avoid need constant temperature store medical article occur quality change.
To achieve the goals above, the present invention adopts the following technical scheme: the present invention provide it is a kind of with fire-proof function
Medical constant-temperature storage device comprising device top and apparatus main body；Described device main body includes at least two layers of cavity shell, institute
Stating two layers of cavity shell is that the first cavity shell and the second cavity shell, above-mentioned shell consist of metal, and the metal is aluminium conjunction
Gold or medical stainless steel；The first cavity shell hollow cavity contains heat-storing material, sets in the second cavity shell hollow cavity
It is set to vacuum；There is insulating layer, the second cavity hull outside and the insulating layer use on the outside of the second cavity housing hollow
Adhesive bonding or mechanical snap；Further include fireprotection layer outside the insulating layer, fire proofing firbre cloth and stone are contained in the fireprotection layer
Ink uses adhesive bonding or mechanical snap between insulating layer and fireprotection layer.
The heat-storing material includes following raw material: ethyl alcohol, deionized water, paraffin, mineral oil, polytetrafluoroethylene (PTFE), zeolite, on
The content of raw material is stated, in parts by weight, 20-30 parts, 5-10 parts, 50-60 parts, 15-20 parts, 25-35 parts, 25-40 parts；The gold
Belong to a thickness of 0.2-1cm.The preparation of the heat-storing material includes the following steps: a, stirs ethyl alcohol, deionized water at 70-80 DEG C
It mixes 30-50min and forms mixture；B, 60~75 DEG C after paraffin and mineral oil, will be warming up to, 40~60min of stirring must be mixed
Close object；C, polytetrafluoroethylene (PTFE) is mixed with said mixture, is continuously heating to 75~85 DEG C, 40~60min of stirring obtains mixture；
D, again said mixture is entered to obtain the heat-storing material in zeolite by vacuum suction.
Since apparatus main body uses the structure of double-layer vacuum cavity shell and external setting insulating layer, thermal insulation property is obtained

Its use temperature range can be expanded by stating paraffin composite phase change material, and in order to avoid the adhesion with cavity wall, the present invention is then with boiling
Masonry is carrier, has the characteristics that porous network structure using it, and the heat-storing material is adsorbed in zeolite effectively to solve
Determined heat-storing material and cavity wall easy adhesion the problem of, accumulation of heat is stored up caused by avoiding the loss of heat-storing material after repeated use
Can efficiency the case where being greatly reduced, the present invention determined the raw material of mentioned kind by research experiment repeatedly, match when technique and
Parameter.The present invention is due to being provided with fireprotection layer structure it is possible to prevente effectively from storage article is damaged in the case where the fortuitous events such as fire occur
The appearance loss, while the thermal insulation property that fireprotection layer itself also has certain heat-blocking action to can be further improved device.
The present invention is further preferred, and the modified processing of zeolite, the modification includes the following steps, a, by graphite
100-150 parts of deionized water ultrasonic disperses are added in 15-20 parts of alkene (by weight), form graphene dispersing solution；B, body is pressed again
The zeolite is immersed in above-mentioned dispersion liquid by product than 1:2, and dip time is 15-20 hours, and dipping temperature is that 40-55 is Celsius
Degree；C, drying and processing is finally carried out.
In use, inventor also found the accumulation of heat that the heat-conducting effect for further promoting zeolite can design the present invention
Material generates more excellent effect, through repeatedly practising and screen finally determine the use of graphene dipping mode handle it is described
Zeolite support, graphene itself has excellent heat conductivity, but there are obstacles for graphene uniform dispersion, therefore the present invention passes through
Dipping is attached to graphene uniform in Zeolite support, also improves the intensity of zeolite and corrosion-resistant additionally by aforesaid way
Property, research experiment has obtained final material rate and technological parameter to inventor repeatedly.
The present invention is further preferred, and two layers of cavity shell is included at least at the top of described device, and above-mentioned shell consists of metal,
The metal is aluminium alloy or medical stainless steel, and two layers of cavity enclosure interior is set as vacuum.Or at the top of described device
