Detailed description of the invention
Specifically, the granularity of above-mentioned accumulation of heat sand grains is 20nm-100mm, and good granularity is 3 μm of-30mm, and best granularity is 20 μm of-5mm.Consider the factors such as the actual grain size of commercially available natural sand, artificial sand, ore in sand form, quartz sand, diamond dust etc., the capacity of heat transmission, raw material and pulverizing processing cost, determine the grit size be suitable for.In general, the sand grains of poor thermal conductivity or the not high sand grains of commercially available fine grained cost, adopt smaller particle size, improve heat storage performance, improves storage heating speed.
Described accumulation of heat sand grains, when the independent accumulation of heat of the accumulation of heat sand grains not containing diamond dust, preferred collocation thermal conducting agent uses quick accumulation of heat heat release, described thermal conducting agent is at least one in graphite, carbon fiber, carbon dust, aluminium oxide, magnesia, zinc oxide, aluminium nitride, metal powder, can be the thermal conducting agent powder of atresia or loose structure.Described metal powder refers to the powder of aluminium, copper, iron, silica flour and the alloy thereof that thermal conductivity is good, price is not too high, preferred copper powder, aluminium powder, silica flour.
Described thermal conducting agent consumption is the 0.1-30% of whole accumulation of heat sand quality, and preferred consumption is 0.3-20%, and best consumption is 0.5-15%.Depending on thermal conducting agent heat conductivility and price determination consumption, as the consumptions such as graphite, carbon fiber, aluminium nitride, metal powder can be less, such as 0.1-5%, and aluminium oxide, magnesia, zinc oxide etc. can add by consumption, as 3-30%.
The enclosure material of described enclosed mass is the one in carbon steel, stainless steel, aluminium, copper, alloy, plastics, rubber, wood, bamboo, pottery, glass, preferred enclosure material is at least one in coating carbon steel, stainless steel, aluminium, alloy, pottery, sun-proof heat-conducting plastic or rubber, can be composite.Can be transparent plastics, rubber or glass, light sand grains preferably arrange in pairs or groups dark thermal conducting agent use; Also can be opaque metal, alloy, preferred scheme carries out metal surface blackening process to reduce reflection, or be coated with the larger dark color of blackness, is beneficial to radiation accumulation of heat.
Preferred shell scheme be upper cover with interface, can vacuumize or the inert gas such as inflated with nitrogen, argon gas or helium, the thermal conducting agent of those easy oxidations by air just can greatly improve service life.Shell can be the bilayer of individual layer or band vacuum interlayer, can also increase security by rounding.
Meanwhile, the invention discloses the preparation method of sand grains accumulation of heat enclosed mass, it is characterized in that, the method comprises the following steps:
1) by least one in river sand, lake sand, mountain sand, extra large sand, Desert Sand, artificial sand, ore in sand form, quartz sand, diamond dust, clean, pulverize and or sieve, obtain the accumulation of heat sand grains of designated size;
2) by one or more accumulation of heat sand grains of described designated size, and or thermal conducting agent, by stirring, grinding or the method such as ball milling mix, and loads the obtained sand grains accumulation of heat enclosed mass of sealing in accumulation of heat sand grains shell;
With or 3) when there being the thermal conducting agent of easy oxidation by air to exist, by shell with interface vacuumize or the inert gas such as inflated with nitrogen, argon gas or helium, then seal protection, obtained sand grains accumulation of heat enclosed mass.
In order to illustrate how the present invention implements, the purposes of the sand grains accumulation of heat enclosed mass that open said method obtains, includes but not limited to these purposes.
This sand grains accumulation of heat enclosed mass can be used as cheap solar heat-preservation body and uses, on roof, balcony, Che Shang, vacant lot, the much places accumulation solar energy such as sea.Preferred scheme is placed on by sand grains accumulation of heat enclosed mass to be full of in the airtight transparent vessel of sunlight, the adiabatic heat-insulation cushion blocks such as bottom pad foam, reduces convection current, heat loss through conduction, improves accumulation of heat effect.
This sand grains accumulation of heat enclosed mass can be used as the place that high temperature furnace, gas-cooker etc. have heat loss through radiation or used heat, reaches minimizing heat loss through radiation, improves operating thermal environment, simultaneously the object of accumulation heat energy.For high temperature furnace, place that gas-cooker surrounding equitemperature is higher, preferred enclosure material is resistant to elevated temperatures stainless steel or pottery, to damage shell.
Concerning family or restaurant's cooking, the trouble often run into is, cold weather is because the temperature difference is very large between Hot dishes product and room temperature, the Hot dishes fried above is a little while just cool, waits all to have fried or guest is late when arriving, and needs again to reduce phlegm and internal heat with micro-wave oven, waste electric energy, also affects vegetable delicate flavour and mouthfeel.After sand grains accumulation of heat enclosed mass provided by the invention accumulation of heat, can be used as the Active Compensation thermal source of the food heat loss such as the Hot dishes in incubator, heat-preserving container, hot side bag, the temperature difference between hot food and storage environment is significantly reduced, and temperature retention time extends greatly.
After the accumulation of heat of sand grains accumulation of heat enclosed mass, can be used as the thermal source of sand-bath physiotherapy couch, dish water can be heated and improve detersive efficiency.
Can also substitute hot-water bottle and warm up quilt, warm hand, warm pin, warm belly, preferred scheme is the coated non-woven fabrics in outside of enclosed mass shell or the protecting band (not drawing in the drawings) of plastic cement, and mediate contact skin, reaches anti-scald or grease proofing, dust-proof object.
After the accumulation of heat of sand grains accumulation of heat enclosed mass, can be used as the auxiliary thermal source of reaction raw materials preheating, chemical reactor or equipment pipe, reduce energy consumption.
During as such use, when system calorific requirement is more, preferred scheme is the sand grains accumulation of heat enclosed mass of preparation more than 2, is used alternatingly, and has an accumulation of heat at least, has an energy heat supply at least.
The present invention is not limited to the above-mentioned scheme in order to implementation method is described, any under the present invention program's enlightenment, the approximate evolutionary approach of the shape of making, structure, composition, all drops within protection scope of the present invention.
