Abstract
The utility model discloses a hot runner heater which comprises a hot running tank. A heating device is arranged in the heat running tank, the heating device comprises spiral resistance heating wires, and the outer walls of the resistance heating wires are in contact with the inner wall of the hot running tank. The hot runner heater is simple in structure, convenient to use and good in heating effect. By means of the hot runner heater, fuel oil can be heated before burning, the functions of reducing viscosity of the fuel oil, promoting complete pulverization and combustion and the like are achieved at the high temperature of 105-150 DEG C, and thus the purpose of energy conservation is achieved. The hot runner heater is an energy-efficient device which is capable of preheating or reheating the fuel oil.
Description
Technical field
The utility model relates to a kind of heater, especially relates to a kind of hot flow path heater, is widely used in heavy oil, pitch, the heating in advance of the fuel oil such as edible vegetable oil or the occasion of post bake.
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-coating Ceng Yuqi center of combining closely and distributing along resistance wire twisted wire total length formed that a monoblock 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 insulaion 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 insulaion 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.In the proportion of fuel oil due to himself, vicidity is large, and in the process of using, the effect that first reach atomization could be burnt, and needs to consume a large amount of heats during this.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of hot flow path heater is provided, this hot flow path heater structure is simple, easy to use, heating effect is good, realizes to fuel oil heating before burning, make it be issued to the viscosity that reduces fuel oil at high temperature (105 ℃-150 ℃), promoting the effects such as abundant spray burning, finally reach the purpose of saving the energy, is a kind of fuel oil to be heated or the energy-saving equipment of post bake in advance.
The purpose of this utility model is achieved through the following technical solutions: a kind of hot flow path heater, comprise the hot-fluid cylinder, and be provided with heater in described hot-fluid cylinder.
Described heater comprises spiral helicine resistive heater, and the outer wall of described resistive heater contacts with the inwall of hot-fluid cylinder.
Be provided with fixed cover on the outer wall of described hot-fluid cylinder, the two ends of described fixed cover are provided with boss.
