Abstract
The invention discloses an electric heater with the anti-explosion function. The electric heater comprises a shell, wherein one end of the shell is opened. A plurality of rows of supporting plates which are arranged in parallel are arranged in the shell, a plurality of heating cables are arranged on all the supporting plates, an installing plate is arranged at the open end of the shell, a terminal box is arranged at the end, away from the shell, of the installing plate, and the heating cables are connected with the terminal box. The electric heater is simple in structure, and the cables are used for heating, so that the heating effect is good; through holes are used for being communicated with the interior of the electric heater, so that heat can be dissipated; unexpected cases can be prevented from occurring through the protection of the shell, and therefore safety of operators is protected.
Description
Technical field
The present invention relates to electric heater, especially relate to the electric heater with explosion prevention function.
Background technology
According to the acquisition of heat energy, can be divided into directly and two classes indirectly.The direct heat source heating is that heat energy directly is added on to material, as flue gas heating, current flow heats and solar radiant energy heating etc.The thermal source heating is thermophore in the middle of the heat energy of above-mentioned direct heat source is added on to indirectly, then by middle thermophore, heat energy is passed to material again, as Steam Heating, hot water heating, mineral oil heating etc., and directly heating
:be applicable to temperature, without the experiment that accurately requires and need be rapidly heated, to comprise every the asbestos gauge heating and not heat every asbestos gauge
;heating bath
:directly heating causes and is heated while being heated together inhomogeneous or difficult control of temperature, can adopt 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 middle school chemistry, the experiment of heating water bath commonly used has: the 1. 4. 5. 6. 7. cellulosic hydrolysising experiment (boiling water bath) of the hydrolysising experiment of sucrose (boiling water bath) of preparation of phenolic resins of the producing of nitrobenzene (thermometer inserts in water-bath) of the 2. 3. hydrolysis of ester of silver mirror reaction (without thermometer) of the mensuration of KNO3 solubility (thermometer inserts in solution) (thermometer inserts in water-bath).Be wound with glass fibre and strengthen refractory fiber floor outside multiply resistance wire twisted wire, be woven with wire and strengthen refractory fiber floor outside refractory fiber floor, the resistance wire twisted wire at the double-coated Ceng Yuqi center of combining closely and distributing along resistance wire twisted wire total length formed that an integral type can arbitrarily bend as required and can with the direct heating monomer of heated object close contact, the heating monomer is by the shape of heating object, size is with sheet repeatedly and around forming, then with wire, many monomers arranged side by side are laterally worn and woven together, formation can directly be enclosed and be wrapped in the Weaving type high temp. electrical heater directly used on heating object.Element allows to work under the following conditions: the A. relative air humidity is not more than 95%, non-explosive and corrosive gas (except anti-explosion 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 temperature and the heating load of wiring part for a long time, when terminal screw is fastening, should avoid overexerting.Element should leave dry place in, if because of long-term while placing insulation resistance lower than 1M Ω, can be dry in the baking oven of 200 ℃ of left and right, or reduce voltage energising heating, until the recovery insulation resistance.The magnesia powder of electrothermal tube leading-out terminal, avoid being subject to pollutant and moisture and infiltrate in field of employment, prevent the generation of electric leakage accident.When the intensification of flow or static liquid state, gaseous state, solid state medium, insulation, heating, due to structure or the chemical property of material, easily cause occurring the phenomenon of blast, light affect the quality of heatable substance, heavy cause security incident, to this, need to carry out security protection to heater.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art; electric heater with explosion prevention function is provided; this electric heater structure is simple; utilize cable to be heated; that heats is effective, utilizes through hole to be communicated with inside, by dissipation of heat out; the housing protection prevents that fortuitous event from producing, and protected operating personnel's safety.
Purpose of the present invention is achieved through the following technical solutions: the electric heater with explosion prevention function, the housing that comprises an end opening, be provided with the supporting bracket that some rows be arranged in parallel in described housing, be provided with some heating cable on described 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 described housing, an end of described Temperature Detector is fixed on mounting panel.Temperature Detector is for the temperature in housing is detected, and the convenient operation personnel grasp.
Be provided with overtemperature alarm in described housing, an end of described overtemperature alarm is fixed on mounting panel.Overtemperature alarm prevents that high temperature from producing the generation to heater and destroying, and carries out monitoring alarm.
Be provided with several through holes on described housing, described through hole is evenly distributed on the outer wall of housing.The concrete quantity of through hole does not limit, according to the volume of housing, set, and after evenly setting, by the dissipation of heat of housing out, heating effective.
In sum, the invention has the beneficial effects as follows: this electric heater structure is simple, utilizes cable to be heated; that heats is effective, utilizes through hole to be communicated with inside, by dissipation of heat out; the housing protection prevents that fortuitous event from producing, and protected operating personnel's safety.
