Description
Technical field
This utility model belongs to high-temperature heater modular construction class, relates to hot industry, laboratory test, performance test
Etc. the environmental-protection structure of industry and department's heating furnace, particularly relate to one and can reduce box high-temperature heating furnace door appearance
Temperature, exterior wall temperature and the safeguard structure of peripheral temperature.
Background technology
High-temperature heater is widely used in industry, the departments such as hot industry, hot test and high-temperature behavior test
High temperature treating device, box type heater the most therein is the most extensive.
Box high-temperature heater, burner hearth is to be formed by refractory material laying, arranges heating element heater in burner hearth, refractory material it
Outside is metal structure.
Said structure, heated intensification starts to maximum temperature and insulation, and the high temperature heat in burner hearth has stepped through resistance to
Fire lining, the transmission of hardware exterior surface, make the outer wall of heating furnace and ambient temperature improve constantly, heating furnace outer wall office
Portion's temperature is up to more than 200 DEG C, it is easy to causes the security incident such as burn of operator, makes ambient temperature exceed indoor simultaneously
The permissible value of operating temperature, does not meets the requirement of safety and environmental protection.Particularly fire door position, because furnace high-temperature air is in malleation,
Just have substantial amounts of thermal current at the gap at fire door position and flow to outside body of heater, serious fire of also leaping up outside stove, not only accelerate
The acute liter of ambient temperature, makes the upper outer of fire door by sooting, variable color, deformation, damages body of heater profile, destroy the tight of structure
Property, shorten the service life of heating furnace, and the harmful gas that in testing, some material produces can spill into laboratory.
Summary of the invention
It is dangerous that the purpose of this utility model is to overcome that prior art furnace wall surface temperature is too high, be susceptible to burn etc.
Smolder at accident and fire door, sooting, variable color, deformation, furnace gas overflow and pollute the deficiency such as environment, it is provided that one has environmental protection and prevents
The high-temperature heater of protection structure.
The purpose of this utility model can realize by the following technical solutions: a kind of high temperature with environmental-protection structure
Heating furnace, including body of heater frame, interior furnace shell, heater element, arranges refractory material in interior furnace shell, arranges outer stove outside interior furnace shell
Shell, inside and outside double-deck furnace hull shape becomes air channel, and outer furnace shell one side opening at fire door also arranges fire door, at interior furnace shell and outer furnace shell
Furnace roof cover plate is installed at top, is connected with each other between furnace roof cover plate and outer furnace shell, and described furnace roof cover plate is arranged on outer furnace shell,
Being provided with furnace roof cover plate perforate on furnace roof cover plate, the air channel that furnace roof cover plate perforate is formed with interior furnace shell and outer furnace shell communicates, at stove
Installing air draft pipe in lamina tecti perforate, arrange blower fan among air draft pipe, air draft pipe is passed through air.
The gap of 5mm is at least left on described furnace roof cover plate and interior furnace shell top.
Described air draft pipe, its end can input exhaust-gas treatment room.
After described body of heater, the top of outer furnace shell is provided with pore, arranges air draft pipe on pore.
The described refractory material at fire door stretches out interior furnace shell, and the outer furnace shell at fire door matches with fire door.
Advantage of the present utility model: inner furnace body and external furnace body all around and above five form passages on the basis of,
By the pipeline air draft at bell or external furnace body, greatly enhance cooling-down effect；Updraft at fire door, fire door black
Cigarette, thermal current are pumped by pipeline；Make furnace wall temperature be greatly reduced, make no longer to have at fire door over-emitting black exhaust, metallic plate variable color,
The defects such as deformation；Improve operating environment, ensured safety, extend the heating furnace life-span.Reduce the cold end of heater element simultaneously
Temperature, extends the life-span of heater, aluminium foil strip and dop, improves reliability.
