The heater housing, the heater housing is made up of three parts, and heater housing homonymy two ends and unidirectional valve compression bar corresponding position are provided with two through hole; Two through hole holds the compression bar of unidirectional valve; Heater is positioned at the heating chamber at heater housing middle part, and the hot-blast outlet of heater communicates with the gas outlet through through hole, and the air inlet of heater communicates with air inlet through through hole; The air inlet outer end of heater is provided with fan, and a side of heater is provided with control box;
The butt joint stationary pipes, the heater case body is positioned at heater housing through hole outer end, is used for and the sealing that is spirally connected of air inlet and outer end, gas outlet.Described unidirectional valve is formed by holding spring, one-way cock and compression bar; Compression bar upper end is convexly equipped with outside air inlet and gas outlet on the transverse plane; The compression bar lower end is the T type and forms the unidirectional valve start and stop lever, and the unidirectional valve start and stop lever holds the leakproof one-way valve door, and unidirectional valve start and stop lever lower end is provided with and holds spring.Described heater is toroidal, and its air inlet diameter is provided with dividing plate greater than the hot-blast outlet diameter between hot-blast outlet and the corresponding shell inwall.Be provided with the thermostat of control heater and electric motor starting in the described control box, the probe of thermostat is positioned at tank body.Described thermostat control temperature range is 5 ℃～50 ℃.The said structure design has realized the object of the invention.
The present invention is positioned at the tank body outside, directly to the tank interior gas heated, has simple in structurely during heating, and the efficiency of heating surface is high, and firing rate is fast, and cost is low, and convenient for maintaining is time saving and energy saving, the advantage of safe and reliable and long service life.Heating cost of the present invention reduces by 90% than conventional method, and firing rate is fast 80%, need not to arrange specially people's heating operation.
Description of drawings
Figure is a structural representation of the present invention.
Embodiment
As shown in the figure, a kind of heating apparatus that is used for the sulphur hexafluoride of low temp area use mainly is made up of heater housing 2, tank body 11 and 3 of heaters.Also comprise:
The heater housing, the heater housing is made up of three parts, and heater housing homonymy two ends and unidirectional valve compression bar corresponding position are provided with two through hole 1, and two through hole holds the compression bar 7 of unidirectional valve.Heater is positioned at the heating chamber 5 at heater housing middle part, and the hot-blast outlet of heater communicates with the gas outlet through through hole.The air inlet of heater communicates with air inlet through through hole.The air inlet outer end of heater is provided with fan 6, and fan is driven by fan electromotor 4.One side of heater is provided with control box 15, is provided with control circuit board 16 in the control box, and control circuit board is provided with thermostat, the keying of thermostat may command heater and fan electromotor.The adjusting knob 17 of regulating thermostat is positioned at the control box outer end.
Butt joint stationary pipes 9, the heater case body is positioned at heater housing through hole outer end, is used for and the sealing that is spirally connected of air inlet and outer end, gas outlet.
Described unidirectional valve is formed by holding spring 14, one-way cock 8 and 7 of compression bars; Compression bar upper end is convexly equipped with outside air inlet and gas outlet on the transverse plane; The compression bar lower end is the T type and forms unidirectional valve start and stop lever 10; The unidirectional valve start and stop lever holds the leakproof one-way valve door, and unidirectional valve start and stop lever lower end is provided with and holds spring.
Described heater is toroidal, and its air inlet diameter is provided with dividing plate 19 greater than the hot-blast outlet diameter between hot-blast outlet and the corresponding shell inwall.The effect of dividing plate is to prevent that cold air from flowing out heating chamber.Can guarantee that like this cold wind that is blown into heater by fan can be heated fast.
Be provided with the thermostat of control heater and electric motor starting in the described control box, the probe 18 of thermostat is positioned at tank body, and the probe of thermostat should be away from air inlet.Described thermostat control temperature range is 5 ℃～50 ℃.
