The heating cables are connected with the junction box. The electric heater is simple in structure. Meanwhile, cables are adopted for heating, so that the electric heater is good in heating effect. The cables are communicated with the interior of the electric heater thorough through holes, and the heat dissipation of the cables is also realized through the through holes. Thus, the shell is protected from unforeseen circumstances, while the safety of operators is ensured.
Description
Technical field
The utility model relates to electric heater, especially relates to the electric heater with explosion prevention function.
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 fiber 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 an integral 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 insulation resistance and being lower than 1M Ω, can be dry in the baking oven about 200 ℃, or reduce voltage energising heating, until the recovery insulation 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.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, and the electric heater with explosion prevention function is provided, and this electric heater is simple in structure; Utilize cable to heat; That heats is effective, utilizes through hole to be communicated with inside, and heat is come out; The housing protection prevents that fortuitous event from producing, and protected operating personnel's safety.
The purpose of the utility model realizes through following technical proposals: the electric heater with explosion prevention function; The housing that comprises an end opening; Be provided with the supporting bracket that plurality of rows laterally arranges in the said housing, be provided with some heating cable on the said supporting bracket, the openend of housing is provided with mounting panel; Mounting panel is provided with terminal box away from an end of housing, and heating cable is connected with terminal box.
Be provided with Temperature Detector in the said housing, an end of said Temperature Detector is fixed on the mounting panel.Temperature Detector is used for the temperature in the housing is detected, and is convenient to operating personnel and grasps.
Be provided with overtemperature alarm in the said housing, an end of said overtemperature alarm is fixed on the mounting panel.Overtemperature alarm prevents that high temperature from producing heater generation destruction, carries out monitoring alarm.
Said housing is provided with several through holes, and said through hole is evenly distributed on the outer wall of housing.The concrete quantity of through hole does not limit, and sets according to the volume of housing, after evenly setting, the heat of housing is come out heating effective.
In sum, the beneficial effect of the utility model is: this electric heater is simple in structure, utilizes cable to heat; That heats is effective, utilizes through hole to be communicated with inside, and heat is come out; The housing protection prevents that fortuitous event from producing, and protected operating personnel's safety.
