Summary of the invention
In order to overcome the problem that existing drawing machine heat tracing stove exists, the purpose of this invention is to provide a kind of drawing machine heat tracing stove, effective, safe and reliable, the long service life of this heat tracing stove heat tracing.
The objective of the invention is to realize through following technical scheme:
A kind of drawing machine heat tracing stove is characterized in that: this heat tracing stove comprises housing, fire door, fire door elevating mechanism, furnace lining, heating element heater and hot air circulating system, and said fire door is arranged on the housing and with the fire door elevating mechanism and is connected; Said furnace lining is fixed on the housing, on furnace lining, is provided with the insulation layer; Heating element heater is arranged in the housing and is positioned at the burner hearth both sides; Hot air circulating system comprises circulating fan) and the interior air channel of stove, circulating fan blows in the workspace through the heat of air channel in the stove with heating element heater.
Among the present invention, said housing is to be made up of body frame and hull plate, and furnace lining is fixed on the body frame.Be provided with the high temperature asbestos packing around the said fire door.Said insulation layer is processed by aluminosilicate fiber cotton.Said heating element heater is a U type heating tube.
Fire door of the present invention compresses and adopts pneumatic automatic compacted form, is furnished with the high temperature asbestos packing around the fire door, and simple in structure, sealing property is reliable.After accepting fire door and compressing the signal that puts in place, begin the energising heating, whole course of action phase interconnected lock, stable performance, reliable.When temperature in the stove surpasses warning value, report to the police, open automatically with the protection device security above fire door behind the time of fire alarming.
For stove is rapidly heated, energy efficient improves control accuracy, and furnace lining adopts aluminosilicate fiber cotton as the insulation layer.It has characteristics such as body of heater is light, amount of stored heat is little, long service life.Heating element heater adopts U type heating tube that burner hearth is heated, and heating element heater is arranged in the burner hearth both sides, is convenient to repair and replacement.
The heat that hot air circulating system is distributed heating tube is blown to hot gas in effective workspace through the air channel by circulating fan, is sucked by the inlet scoop in the workspace again, constitutes hot air circulation.Convection walls adopts stainless steel to make.
The present invention adds thermal medium and uses thermal cycle wind in the sealing insulation, has improved the uniformity of temperature, reduces thermal losses.Fire door of the present invention opens and closes for the control of lift cylinder, and reaction speed is fast, need not personnel's contact, has avoided operating personnel's scald.Heat tracing of the present invention is effective, safe and reliable, long service life.The present invention is specially adapted to the heat tracing of closed five roller drawing machines, is used for the drawing-off like fibers such as PTFE.
