Description
Technical field
The present invention relates to a kind of heater, especially relate to a kind of medical heater with explosion prevention function, belong to a kind of equipment being converted to heat energy with electric power of explosion-proof occasion, for medical workshop.
Background technology
According to the acquisition of heat energy, can be divided into directly and indirectly two classes.Direct heat source heating is that heat energy is directly added on material, as flue gas heating, current flow heats and solar radiant energy heating etc.Indirect heat source is that the heat energy of above-mentioned direct heat source is added on a middle thermophore, then by middle thermophore, heat energy is passed to material again, as Steam Heating, hot water heating, mineral oil heating etc., directly heats
:to be applicable to temperature without precise requirements and the experiment that need be rapidly heated, comprise every asbestos gauge heating and do not heat every asbestos gauge
;heating bath
:direct heating causes is heated when being heated uneven or difficult control of temperature together, can adopt indirect.Indirect comprises water-bath, oil bath and sand-bath heating.(1) effect of water-bath: be 1. easy to control temperature and be 2. heated evenly by heating instrument.(2) in middle school chemistry, the experiment of conventional heating water bath has: 1. hydrolysising experiment (boiling water bath) the 7. cellulosic hydrolysising experiment (boiling water bath) of the mensuration (thermometer inserts in solution) of KNO3 solubility 2. silver mirror reaction (without thermometer) 3. ester hydrolysis (thermometer inserts in water-bath) 4. the producing of nitrobenzene (thermometer inserts in water-bath) the 5. preparation 6. sucrose of phenolic resins.Glass fiber reinforcement refractory fiber floor is wound with outside multiply resistance wire twisted wire, outside refractory fiber floor, be woven with wire strengthen refractory fiber floor, combine closely and along the resistance wire twisted wire at double-coating Ceng Yuqi center of resistance wire twisted wire total length distribution constitute a monoblock type can arbitrarily bend as required and can with the direct heating monomer of heated object close contact, heating monomer presses the shape of heating article, size repeatedly and around formation band sheet, then with wire, many horizontal the wearing of monomers arranged side by side are woven together, formation directly can enclose the Weaving type high temp. electrical heater wrapping in and heating object directly uses.Element allows to work under the following conditions: 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 answers effective grounding.Wiring part should be placed on outside heat-insulation layer, 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, should avoid overexerting when terminal screw is fastening.Element should leave dry place in, if because of when placement insulaion resistance is lower than 1M Ω for a long time, can be dry in the baking oven of about 200 DEG C, or reduce voltage electrified regulation, until recover insulaion resistance.The magnesia powder of electrothermal tube leading-out terminal, avoids in field of employment being subject to pollutant and moisture infiltrates, and prevents the generation of electric leakage accident.When medicine production is to the intensification of flowing or static liquid state, gaseous state, solid state medium, insulation, heating, due to structure or the chemical property of material, easily cause the phenomenon occurring blast, light then affect the quality of heatable substance, heavy then cause security incident, to this, need to carry out security protection to heater.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, a kind of medical heater with explosion prevention function is provided, this heater structure is simple, in work, cryogen medium is along the inner specific heat exchange runner of heating container, use the path of thermodynamic fluid principle design, heated medium temperature is raised, and avoid simultaneously and produce blast, safety coefficient is high.
Object of the present invention is achieved through the following technical solutions: the medical heater with explosion prevention function; comprise inner hollow and sealing; be provided with the protective cover of import and outlet simultaneously, in described protective cover, be provided with heating container, between described heating container and protective cover, be provided with some heating tubes.
Described heating tube is evenly arranged between the inwall of protective cover and the outer wall of heating container, and with the wall contacts of heating container.
One end of described protective cover is provided with heating head, and one end of described heating tube is all arranged in heating head.
Overtemperature protection system is provided with in described heating head.
The exit of described protective cover is provided with temperature inductor, and described temperature inductor is connected with overtemperature protection system.
Described heating head is provided with electricity entrance, described overtemperature protection system is arranged in electricity entrance.
Described import is arranged on the one end near heating head.
In sum, the invention has the beneficial effects as follows: this heater structure is simple, in work, cryogen medium is along the inner specific heat exchange runner of heating container, use the path of thermodynamic fluid principle design, heated medium temperature is raised, and avoid simultaneously and produce blast, safety coefficient is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding parts title in accompanying drawing: 1-import; 2-protective cover; 3-outlet; 4-temperature inductor; 5-heating tube; 6-heating head; 7--overtemperature protection system; 8-electricity entrance.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment:
As shown in Figure 1; there is the medical heater of explosion prevention function, comprise inner hollow and sealing, be provided with the protective cover 2 of import 1 and outlet 3 simultaneously; be provided with heating container in described protective cover 2, between described heating container and protective cover 2, be provided with some heating tubes 5.In work, cryogen medium enters the import 1 of heater under pressure by pipeline, along the inner specific heat exchange runner of heating container, use the path of thermodynamic fluid principle design, take away the high-temperature hot energy produced in heating tube work, heated medium temperature is raised, and heater outlet 3 obtains the high-temperature medium of technological requirement.
Between the inwall that described heating tube 5 is evenly arranged on protective cover 2 and the outer wall of heating container, and with the wall contacts of heating container.Evenly arrange heating tube 5, the generation of heat is more even, makes the better effects if heated.
One end of described protective cover 2 is provided with heating head 6, and one end of described heating tube 5 is all arranged in heating head 6.
Overtemperature protection system 7 is provided with in described heating head 6.
Outlet 3 place of described protective cover 2 is provided with temperature inductor 4, and described temperature inductor 4 is connected with overtemperature protection system 7.When heating tube 5 overtemperature; temperature inductor 4 passes the signal along to rapidly in overtemperature protection system 7, and independently overtemperature protection system 7 cuts off heating power supply immediately, avoids heated material overtemperature to cause coking, rotten, carbonization; cause heater element to burn out time serious, effectively extend heater service life.
Described heating head 6 is provided with electricity entrance 8, and described overtemperature protection system 7 is arranged in electricity entrance 8.Electric current can be cut off in time when overheated.
