Abstract
The invention discloses an energy-saving thermal-treatment heating furnace. The energy-saving thermal-treatment heating furnace comprises a furnace body, a furnace lid, and a temperature-control electrical system, wherein an electric heater is arranged in the furnace body, a glass fiber layer is formed on the inner wall of the furnace body, a thermocouple and a vent pipe are arranged on the furnace lid, the thermocouple is connected with the electric heater, one end of the vent pipe is extended into the furnace body, while the other end of the vent pipe is connected with a three-way valve, and a gas inlet pipe is further connected to the three-way valve. The energy-saving thermal-treatment heating furnace is novel in structure; the vent pipe is arranged on the furnace lid and connected with the gas inlet pipe by virtue of the three-way valve, and the gas inlet pipe is connected with a gas tank so that a gas can be introduced so as to prevent oxidization or burning loss of a metal; the glass fiber layer is arranged on the inner layer of the furnace body, has double effects of gas isolation and thermal radiation reflection and also is capable of preventing gas from escaping.
Description
Technical field
The present invention relates to a kind of process furnace, particularly a kind of energy-saving heat treatment heating furnace.
Background technology
Heat treatment heating furnace is indispensable heating installation in metal heat treatmet.Conventionally; in order to prevent that the method for burning, scaling loss from being that the gases such as protective atmosphere heating, nitrogen, argon gas, hydrogen or carbonic acid gas are conventional shielding gas; or employing heating under vacuum; isolated with air; non-oxidation or light heating, wherein use hydrogen shield, welcome especially under many heating conditions; because hydrogen shield not only can anti-oxidation also have very important reductive action, make some reduction reaction smooth.But existing process furnace is made up of body of heater and bell, electric heater is set in body of heater, body of heater and bell are tightly connected, and shielding gas cannot enter, and can not meet people's needs.
Summary of the invention
Object of the present invention is just to provide a kind of novel structure, can be filled with the energy-saving heat treatment heating furnace of shielding gas.
To achieve these goals, the technical solution used in the present invention is such: energy-saving heat treatment heating furnace of the present invention, comprise body of heater, bell and temperature control electrical system, in body of heater, be provided with electric heater, described inboard wall of furnace body is provided with glass layer, and described bell is provided with thermopair and ventpipe, thermopair is connected with electric heater, ventpipe one end is stretched in body of heater, and the other end is connected with T-valve, is also connected with inlet pipe on T-valve.
As preferably, described bottom of furnace body is provided with underframe.
Compared with prior art, the invention has the advantages that: novel structure of the present invention, ventpipe is set on bell, ventpipe connects inlet pipe by T-valve, inlet pipe connects gas-holder can be filled with gas, prevents burning or scaling loss, and inboard wall of furnace body is provided with glass layer, there is isolated gas and reflective thermal radiation dual function, prevent gas leak.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, energy-saving heat treatment heating furnace of the present invention, comprise body of heater 1, bell 2 and temperature control electrical system, be provided with electric heater 4 in body of heater 1, described body of heater 1 inwall is provided with glass layer 3, described bell 2 is provided with thermopair 5 and ventpipe 6, thermopair 5 is connected with electric heater 4, and ventpipe 6 one end are stretched in body of heater 1, and the other end is connected with T-valve 7, on T-valve 7, be also connected with inlet pipe, described body of heater 1 bottom is provided with underframe 8.
Ventpipe 6 is set on bell 2, and ventpipe 6 connects inlet pipe by T-valve 7, and inlet pipe connects gas-holder can be filled with gas, prevent burning or scaling loss, body of heater 1 inwall is provided with glass layer 3, has isolated gas and reflective thermal radiation dual function, prevents gas leak.
