The heater is simple in structure; and during operation, the low-temperature fluid medium flows along with a specific heat exchange channel inside the heating container, and the path designed by employing a fluid thermodynamic principle, so that the temperature of the heated medium is raised, the explosion is avoided, and the safety coefficient is high.
Description
Technical field
The utility model relates to a kind of heater, especially relates to a kind of medical heater with explosion prevention function, and what belong to explosion-proof occasion converts a kind of equipment of heat energy into electric power, is used for medical workshop.
Background technology
According to the acquisition of heat energy, can be divided into direct and indirect two types.The direct heat source heating is that heat energy directly is added on material, like flue gas heating, current flow heats and solar radiant energy heating etc.Indirectly the thermal source heating is a thermophore in the middle of heat energy with above-mentioned direct heat source is added on, by middle thermophore heat energy is passed to material more then, like Steam Heating, hot water heating, mineral oil heating etc., directly heats
:Be applicable to the experiment that temperature is not had accurate requirement and need be rapidly heated, comprise at a distance from asbestos gauge heating and separated asbestos gauge heating
Heating bath
:Directly heating causes to be heated and is heated inhomogeneous together or during difficult control of temperature, can adopts indirect.Indirect comprises water-bath, oil bath and sand-bath heating.(1) effect of water-bath: 1. be easy to control temperature and 2. be heated instrument and be heated evenly.(2) in the middle school chemistry there be the experiment of water-bath heating commonly used: the 1. 4. 5. 6. 7. cellulosic hydrolysising experiment of the hydrolysising experiment of sucrose (boiling water bath) (boiling water bath) of preparation of phenolic resins of the producing of nitrobenzene (thermometer inserts in the water-bath) of the 2. 3. hydrolysis of ester of silver mirror reaction (without thermometer) of the mensuration of KNO3 solubility (thermometer inserts in the solution) (thermometer inserts in the water-bath).Outside multiply resistance wire twisted wire, be wound with glass fibre and strengthen refractory fiber floor; Outside refractory fiber floor, be woven with wire and strengthen refractory fiber floor; The double-coated layer of combining closely and distributing along resistance wire twisted wire total length and the resistance wire twisted wire at its center have been formed a monoblock type can arbitrarily bend also the direct heating monomer that can closely contact with heated object as required; The heating monomer by the shape, size of heating object repeatedly and around forming the strap shape; With wire many monomers arranged side by side are laterally worn then and woven together, formation can directly be enclosed and wrapped in the Weaving type high temperature electric heater that directly uses on the heating object.Element allows under following condition, to work: the A. relative air humidity is not more than 95%, non-explosive and corrosive gas (except the explosion-proof heater); B. operating voltage should be not more than 1.1 times of rated value, and shell is ground connection effectively.The wiring part should be placed on the heat-insulation layer outside, avoids and corrosivity, explosive medium, contact with moisture; Lead wire should be able to bear the temperature and the heating load of wiring part for a long time, should avoid when terminal screw is fastening overexerting.Element should leave dry place in, if because of long-term when placing insulaion resistance and being lower than 1M Ω, can be dry in the baking oven about 200 ℃, or reduce voltage energising heating, until the recovery insulaion resistance.The magnesia powder of electrothermal tube leading-out terminal is avoided receiving pollutant and moisture and is infiltrated in the field of employment, prevent the generation of electric leakage accident.In medicine production to flowing or when the intensification of static liquid state, gaseous state, solid state medium, insulation, heating; Because the structure or the chemical property of material; Cause the phenomenon that occurs exploding easily, light then influence the quality of heatable substance, heavy then cause security incident; To this, need carry out security protection to heater.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art; A kind of medical heater with explosion prevention function is provided, and this heater structure is simple, and the cryogen medium is along the inner specific heat exchange runner of heating container in the work; The path of utilization thermodynamic fluid principle design; The heated medium temperature is raise, avoided producing blast simultaneously, safety coefficient is high.
The purpose of the utility model realizes through following technical proposals: the medical heater with explosion prevention function; Comprise inner hollow and sealing; Be provided with the protective cover of import and outlet simultaneously; Be provided with heating container in the said protective cover, be provided with some heating tubes between said heating container and the protective cover.
Said heating tube evenly is arranged between the outer wall of inwall and heating container of protective cover, and contacts with the outer wall of heating container.
One end of said protective cover is provided with heating head, and an end of said heating tube all is arranged in the heating head.
Be provided with overtemperature protection system in the said heating head.
The exit of said protective cover is provided with temperature inductor, and said temperature inductor is connected with overtemperature protection system.
