Background technology
The various industrial furnace of metallurgy industry needs due to technique, inevitably need on body of heater, offer various hole, the equipment such as feed rods, probe stretches into inside stove, and expect the equipment such as bar, probe generally require do before and after, upper inferior motion, cause opening furnace walls relatively big and be inconvenient to do encapsulation process.If but do not carry out encapsulation process, then there are the following problems:
1. industrial furnace typically uses pressurized operation, if opening furnace walls does not use sealing device, high-temperature furnace gas can be excessive at opening furnace walls, causes radiation loss, and time serious, high-temperature furnace gas can damage stove external equipment, affects the properly functioning of stove.
2. industrial furnace running temperature is higher, if not sealing perforate, hyperthermia radiation is directly radiated outside equipment and personnel by perforate, causes radiation loss, affects equipment life, environment is caused light pollution, impacts personnel health.
3. affected by excessive high-temperature furnace gas and hyperthermia radiation at industrial furnace opening furnace walls, harsh environmental conditions, brought inconvenience to equipment routing inspection and maintenance.
Therefore, a kind of body of heater hole sealing device of research and development, holes various on industrial furnace effectively can be sealed, to reducing heat loss, to improve working environment significant.
Summary of the invention
In consideration of it, it is an object of the invention to provide a kind of body of heater hole sealing device, solve metallurgy industry various industrial furnace opening furnace walls sealing problem, to reduce the radiation loss of industrial furnace, the outer plant equipment of protection stove, improve operating environment near stove hole.
For reaching above-mentioned purpose, the present invention is achieved through the following technical solutions:
A kind of body of heater hole sealing device, including the housing being fixed on body of heater, the air partition device that is fixed on housing, described air partition device includes the air insulated cover covering on body of heater hole edge and to providing the air supply system sealing gas in described air insulated cover, described air insulated cover include air frame and can the movable cover cap that moves up and down of the directive slide track along housing, described movable cover cap is provided with a via adapted with the cross section of object in entrance stove.
Further, described air supply system includes that the air jet orifices being arranged on air frame and the air duct connected with air frame, described air duct connect with extraneous source of the gas.
Further, described air supply system is provided with two sets, and separate setting altogether.
Further, described housing is provided with the directive slide track that described movable cover cap carries out moving up and down.
Further, described movable guard lid is additionally provided with the blocking mechanism for being separated with object upper surface in entrance stove by movable cover cap.
Further, described blocking mechanism is assembly pulley, and described assembly pulley is fixed with described movable cover cap by fixing seat.
The beneficial effects of the present invention is:
Furnace high-temperature furnace gas and hyperthermia radiation are blocked by the present invention by air partition device; reduce the heat loss of industrial furnace, the outer plant equipment of protection stove, improve working environment near body of heater; and by cover cap being set to movable cover cap; make it have the degree of freedom moved with object in entrance stove, expand its scope of application.
