According to the invention, an asbestos wire gauze is substituted; in a using procedure, the heat insulating device plays a role by dint of change of physical performance of the heat insulating device; in addition, the heat insulating device has safe, non-toxic, environmental-friendly, acid-resist, alkali-resist, moisture-resistant and the like performances and is characterized by low and easily-acquired material, energy saving and long service life.
Description
Technical field
The present invention relates to a kind of heat-proof device, it belongs to chemical experiment articles for use technical field.
Background technology
When the laboratory experiment personnel use heating such as alcolhol burner, electric furnace to fill the glassware of liquid; If glassware directly contacts electric furnace; Flame is concentrated in certain place of container for a long time, finally can make the glassware explosion, and traditional experimental implementation is on electric furnace, to put an asbestos gauge.Asbestos gauge clips an asbestos fibre by two wire nettings and behind water logging bubble, dries and make.Asbestos fibre has acid and alkali resistance, and heat insulation, insulation, fire prevention, To Be Protected from Heat, characteristic such as not flammable, is traditional heat-insulation and heat-preservation material.Use the heat of back flame will be distributed to the every nook and cranny of container, burning glassware for a long time can explosion yet, and iron wire can pass to the container top with the spread heat of flame in air, vessel are heated evenly.But also there is following defective in asbestos gauge: 1, asbestos gauge non-refractory, just begin efflorescence more than reaching 500 degree, on alcohol blast burner or electric furnace calcination very easy to be cracked, and pollute electric furnace, the iron wire of the inside comes out and causes short circuit easily.It almost is disposable product; 2, asbestos are prone to humidity, come off easily behind the chance of the making moist water; 3, asbestos fibre is harmful; Stimulate people's respiratory system, it is the almost invisible fibers of a kind of very tiny naked eyes, after these tiny fibers discharge, can swim for a long time in air; Be inhaled in the human body; The asbestos fibre that is inhaled into can accumulate in the person for many years, causes PUD D, causes potential threat to the experimenter is healthy.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of heat-proof device with performances such as safety, environmental protection, moisture resistance, long service life is provided.
The technical scheme that the present invention solves the problems of the technologies described above is following:
A kind of heat-proof device comprises the explosion-proof ware that has lid, is provided with grains of sand thermal insulation layer in the said explosion-proof ware.
Compared with prior art, the invention has the beneficial effects as follows: 1, replace asbestos fibre with grains of sand thermal insulation layer, nontoxic, no burn into is pollution-free, health environment-friendly; 2. security performance is high, and the iron plate immersion heater is cold soon, does not have danger, and grains of sand thermal insulation layer can prevent that the glassware of its top is quick-fried strong; 3, nonhygroscopic, stable performance, long service life; 4, high temperature resistant, economize on electricity can, iron and the grains of sand are high temperature resistant, porosity is bigger between the grains of sand, heat up to accelerate, and the grains of sand can also the heat build-up insulation, can make heating object continue intensification after shutting electric furnace; 5, raw material is easy to get, and cost is low, produces easyly, economic and practical, and the grains of sand also can be gathered materials on the spot.6, acidproof, alkaline-resisting, applied widely, go for any experiment field.
On the basis of technique scheme, the present invention can also do following improvement.
Further, said explosion-proof ware below is provided with bearing, and said bearing comprises the support that has supporting network, is provided with and the corresponding groove of explosion-proof ware external diameter in the middle of the said supporting network.
The beneficial effect that reaches through above-mentioned further technical scheme is: easy to use, can be positioned over multiple heater top easily.
Further, the shank of said support is equipped with garment bag.
The beneficial effect that reaches through above-mentioned further technical scheme is: garment bag can carry out effective thermal insulation protection to support.
Description of drawings

Fig. 2 is the vertical view of bearing of the present invention.
Supporting network in the drawings, 1; 2, explosion-proof ware; 3, lid; 4, grains of sand thermal insulation layer; 5, support; 6, garment bag; 7, groove.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
A kind of heat-proof device comprises the explosion-proof ware 2 that has lid 3, is provided with grains of sand thermal insulation layer 4 in the said explosion-proof ware 2; Said explosion-proof ware 2 belows are provided with bearing; Said bearing comprises the support 5 that has supporting network 1, and the shank of said support 5 is provided with garment bag 6, is provided with and the corresponding groove 7 of explosion-proof ware 2 external diameters in the middle of the said supporting network 1.
The present invention is when making: said explosion-proof ware 2 is a cylinder, is processed by thickness 0.1-0.15cm iron plate, and its diameter is 11.5cm, highly is 0.5cm; The diameter of the said grains of sand is 3.0-4.5mm, and thickness is one deck grains of sand, and the upper surface of the upper surface of promptly said grains of sand thermal insulation layer 4 and supporting network 1 is on same horizontal plane; Said support 5 is all made with iron wire with supporting network 1; Said supporting network 1 integral body is square, is of a size of 14.4*14.5, and intermediate groove 7 positions do not have net; Said support 5 is to be that iron plate about 0.15cm intersects and to make by four thickness, curves the shank of support 5 vertically downward at the 2-3cm place of leaving supporting network 1, and the height of support 5 is 21cm.
The present invention is in use: when heating liquid, at first it is positioned over the electric furnace top, opens lid 3, grains of sand thermal insulation layer 4 is placed; The beaker that will fill liquid to be heated then is positioned over the top of grains of sand thermal insulation layer 4, opens the electric furnace heating, till achieving the goal.In use because the grains of sand have insulation, can treat the reddening of explosion-proof ware 2 after, reduce gear or close electric furnace, its waste heat can continue to heat up, and saves electric energy.Finish using, beaker is taken off, and lid 3 is covered on explosion-proof ware 2, can prevent effectively that the grains of sand of grains of sand thermal insulation layer 4 in the explosion-proof ware 2 are unrestrained.
