Abstract
The utility model discloses an energy-saving and air-cooling thermocouple testing furnace, comprising an outer furnace casing, a hearth tube, an inner furnace frame, a heat-endurable insulation layer and a fan. The hearth tube is arranged in the middle of the outer furnace casing and the inner furnace frame is arranged outside the hearth tube, and the heat-endurable insulation layer is arranged between the hearth tube and the inner furnace frame, and the fan is arranged at the center of the bottom of the outer furnace casing and a vent is respectively positioned at two ends of the outer furnace casing. The test of precious metal thermocouple of the testing furnace of the utility model is less than 2 hours and the highest equal temperature zone of the testing furnace can be kept stable in 5 hours. And if the testing furnace can not be physically damaged dramatically, the highest equal temperature zone can be kept stable all along. When in use, the fly-ash can be avoided and the harmful air can not be emitted, and the temperature-rising power is less than 0.4 kilowatt and the constant temperature power is less than 0.1 kilowatt. As the testing furnace adopts the air-cooling, the heating on the surface of the furnace casing can be avoided, and after testing, the hearth temperature can be decreased quickly and the power can be raised in constant running.
Description
Technical field
The utility model relates to a kind of electric thermo-couple test furnace, especially a kind of air-cooled electric thermo-couple test furnace.
Background technology
At present, domestic electric thermo-couple test furnace quantity in usefulness surpasses 20,000, existing electric thermo-couple test furnace exists that energy consumption is higher, intensification power greater than more than 2 kilowatts and also heating and cooling, constant temperature slow, warm field stability is poor, the length of uniform temperature field is constantly dwindled.Simultaneously, casing temperature is higher.
Summary of the invention
It is low that technical problem to be solved in the utility model provides a kind of energy consumption, and heating and cooling, constant temperature are quick, the energy-saving air-cooled electric thermo-couple test furnace that warm field stability is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of energy-saving air-cooled electric thermo-couple test furnace comprises outer furnace shell, furnace tube, interior grate, heat-resisting heat-insulation layer, blower fan; Furnace tube is arranged in the middle of the outer furnace shell, and furnace tube is provided with interior grate outward, is provided with heat-resisting heat-insulation layer between furnace tube and the interior grate, and blower fan is equipped with in outer furnace shell bottom centre, and outer furnace shell two ends set ventilating opening.
Heat-resisting heat-insulation layer is an insulating brick; Insulating brick thickness is greater than 75 millimeters, unit weight 3g/cm
