Abstract

The utility model relates to a self-temperature control heat preserving box which comprises a box body with a body door, and a plurality of rows of electric heating belts laid in the box body. The utility model is characterized in that the box body formed by bending a metal plate comprises an inner layer and an outer layer; the electric heating belts of which the surfaces are covered with aluminum platinum adhesive tapes and the final ends of the electric heating belts are fixedly sealed with the wall of the inner layer; anticorrosion layers are arranged on the outer surfaces of the electric heating belts; the beginning ends of the electric heating belts are in compression joint with an externally connected power cord through pressing elements with insulating layers; heat shrinking pipes are arranged on the outer surfaces of the electric heating belts; heat preserving materials are filled between the inner layer and the outer layer of the box body; the middle upper part of the box door is provided with a double-layer toughened glass observing window; a temperature gauge is fixed in the observing window. No heating elements and temperature control components are arranged in the box body; all the space in the box is used for installing instruments. Because the temperature of the box body automatically regulates, the four walls of the box body supply heat continuously and evenly, which ensures that the instruments in the box works under a constant temperature; the utility model has the advantages of high safety and reliability, stable performance and long service life; the utility model is particularly suitable for being used in anticorrosion and explosive-proof regions.

Description

Temperature self-control insulation cabinet

Technical field

The utility model relates to a kind of incubator, relates in particular to a kind of temperature self-control insulation cabinet.

Background technology

Traditional instrument incubator is that the employing electric tube heater adds thermostat or the steam tracing structure is controlled the temperature inside the box.In the use, the malfunctioning or steam leakage of thermostat causes the temperature inside the box overheated or cold excessively sometimes, makes that protected instrument is impaired, even scraps.Simultaneously, the run, drip, leak phenomenon very easily appears in steam tracing device structure complexity, huge, the failure rate height, and maintenance is big, and the heat efficiency is also lower, the sophisticated equipment and the production environment of incompatible modernized industrial and mineral enterprise.Up to now, in China's industrial circle, also do not have the extensive utilization and extention electrical heat energy of a kind of energy conversion, not only be applicable to the general industry occasion but also can be used for the temperature self-control insulation cabinet of explosion-proof occasion.

The utility model content

The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and a kind of temperature self-control insulation cabinet is provided, and it can make, and heat-insulating property is stable, heating efficiency is high, the life-span is long, observe temperature conveniently, can use safely again in explosion-proof, anticorrosion zone.

For realizing the purpose of this utility model, the technical scheme that is adopted is: a kind of temperature self-control insulation cabinet, comprise that the casing and the many rows that are with chamber door are laid in the interior ribbon heater of casing, it is characterized in that: the casing that is bent by metallic plate comprises that internal layer is with outer, the ribbon heater of described surface coverage aluminium platinum adhesive tape and terminal thereof and casing inner layer wall seal admittedly, the ribbon heater outer surface is provided with explosion-proof, anticorrosive coat, top, described ribbon heater is the top by the crimp of tape insulation layer and external power supply line pressure knot, glue sealingization, and at top appearance reduction of area heat-shrink tube is housed; Fill insulant material between described casing internal layer and the skin; Described chamber door middle and upper part is provided with double-deck tempering glass vision panel, intrinsic temperature meter in the form.

Described casing adopts cold-rolled steel sheet, corrosion resistant plate.

But described ribbon heater is the anticorrosion of self-regulation power, explosion-proof ribbon heater.

Described temperature is counted the passive type thermometer.

The beneficial effects of the utility model are that no any heating element and temperature control assembly in casing make the interior all spaces of case be used for installing instrument.Because spin manifold temperature is regulated automatically, by the continuous even distribution heating of its wall, instrument is worked under constant temperature in the guard box, and is safe and reliable, stable performance.Non-maintaining, the long service life of incubator.It is particularly suited for using in anticorrosion, explosion-proof area.

Fig. 2 is the schematic diagram of chamber door among Fig. 1;

Fig. 3 is a heat-shrink tube structure for amplifying schematic diagram among Fig. 1.

Embodiment

Accompanying drawing is embodiment of the present utility model, describes embodiment of the present utility model in detail below in conjunction with accompanying drawing.

With reference to Fig. 1-3, a kind of temperature self-control insulation cabinet, comprise that the casing 2 and the many rows that are with chamber door 1 are laid in the interior ribbon heater 3 of casing, the casing 2 that adopts metallic plates such as cold-rolled steel sheet, corrosion resistant plate to bend comprises internal layer 2-1 and outer 2-2, described ribbon heater and terminal thereof and casing inner layer wall seal admittedly, ribbon heater surface coverage aluminum foil and adhesive tape 3-1, power line is penetrated in the case by the casing wire hole.Top, ribbon heater passes through the crimp 5 and circumscripted power line 6 crimping, glue sealingization of tape insulation layer, and at its appearance reduction of area dress heat-shrink tube 7; The ribbon heater of surface coverage aluminium platinum adhesive tape and terminal thereof and casing inner layer wall seal admittedly, but the ribbon heater is the anticorrosion of self-regulation power, explosion-proof ribbon heater, and its model is 2710-C or 2710-21R, fill insulant material 8 between casing internal layer and the skin; Described chamber door 1 middle and upper part is provided with double-deck tempering glass vision panel 9, and thermometer 10 is housed in the form, temperature in the may observe casing.When casing was applied in anticorrosion, explosion-proof area, through the ribbon heater of the automatic adjusting power of anticorrosion, explosion-proof processing, the method for attachment of 220VAC power supply and ribbon heater was; Employing has the crimp of insulating barrier, behind the bus pressure knot with power line and ribbon heater, and the glue sealingization, the reusable heat draw tightens, heavy insulation and sealing.This way meets international IEE-515 standard.

The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
