The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; The utility model comprises frame 1, blower fan 2, power supply 15 and is arranged on the heating chamber 3 on the frame 1; The outlet of blower fan 2 is connected with the air inlet of heating chamber 3, in heating chamber 3, is provided with at least one group of electric furnace heating wire heater 4, and said electric furnace heating wire heater 4 links to each other with power supply 15.Utilize blower fan 2 bubbling air in heating chamber 3, air is heated through the electric furnace heating wire heater 4 in the heater 3 time, thereby becomes required hot-air.Blower fan 2 air inlets can connect adapted equipment and form hot air circulation, also can not connect other equipment, directly the suction cold air.During work, electric furnace heating wire 12 indirect currents, electric furnace heating wire 12 generate heat rapidly, and blower fan 2 is opened simultaneously, and blower fan 2 is blown into wind in the heating chamber 3, and wind is heated through electric furnace heating wire 12 in heating chamber 3 air channels, and the air outlet from heating chamber 3 blows out then.Electric furnace heating wire heater 4 utilizes electric energy to pass through the electric furnace heating wire heating, when adding hot-air, can not produce waste gas and residue.The heating power of electric furnace heating wire heater 4 can be regulated through the control electric current, when heating, regulates more easily like this.
For the better heating air, like Fig. 1, shown in Figure 2, also comprise at least one dividing plate 32 that is lower than heating chamber 3, said dividing plate 32 is divided at least two end to end air channels 31 with heating chamber 3.It is elongated to make the cold air of entering flow through the distance of heating chamber 3 like this, and the sectional area of cold air reduces, and so just adds hot-air more completely, makes that the air themperature after the heating is evenly distributed.
For the ease of safeguarding electric furnace heating wire heater 4, as shown in Figure 1, slide rail 10 is set on the inwall of heating chamber 3, said electric furnace heating wire heater 4 is installed on the slide rail 10.When safeguarding electric furnace heating wire heater 4, for example deashing is perhaps changed electric furnace heating wire 12, and just can utilize slide rail 10 that electric furnace heating wire heater 4 is extracted out from heating chamber 3 this moment, when operation, just can not receive the obstruction of heating chamber 3 like this.Electric furnace heating wire heater 4 can be through rolling or being slidingly installed on slide rail 10.
Concrete; As shown in Figure 3; Electric furnace heating wire heater 4 comprises electric furnace heating wire 12, heater support 14, is installed in coiling porcelain seat 13 and joint porcelain 11 on the heater support 14; Said electric furnace heating wire 12 is installed on the heater support 14 through coiling porcelain seat 13, and electric furnace heating wire 12 terminations link to each other with power supply 15 through joint porcelain 11.Utilize joint porcelain 11 can separate electric furnace heating wire 12 and heater support 14, thereby prevent that high temperature from exerting an influence to the intensity of heater support 14.
Concrete, as shown in Figure 3, the top and bottom of heater support 14 all are furnished with electric furnace heating wire 12, coiling porcelain seat 13 and joint porcelain 11.So just can make electric furnace heating wire heater 4 structures compact more, possess bigger heating power.
For fear of the air flow blind angle, as shown in Figure 2, the corner of heating chamber 3 inwalls is tiltedly installed with deflector 5.Deflector 5 is equivalent to do chamfered for the turning, and deflector 5 can guide air to turn, thereby the dead angle that prevents corner produces, and prevents the loss of pressure.
Discharge for the ease of the control hot blast, as shown in Figure 1, also comprise air-out chamber 7, said air-out chamber 7 is provided with hot-blast outlet, and 7 said air-out chambeies 7, said air-out chamber are connected the air outlet of heating chamber 3.The effect of a buffering is played in air-out chamber 7, at first gets into air-out chamber 7 through the air after the heating, on the air-out chamber 7 a plurality of outlets can be set, and just can open simultaneously or partially open this moment, satisfies different hot blast demands.
In order to control air output, as shown in Figure 1, the hot-blast outlet place is provided with air-out adjustable plate 8.That air-out adjustable plate 8 can adopt is plug-type, utilize the size of air-out adjustable plate 8 control hot-blast outlets; Also can use rotary shaft, utilize the anglec of rotation of air-out adjustable plate 8 to control the size of hot-blast outlet.
For the temperature of controlled in real-time hot blast, as shown in Figure 1, also comprise heat-sensitive sensor 9, said heat-sensitive sensor 9 is arranged in the air-out chamber 7.Heat-sensitive sensor 9 can be monitored the temperature in the air-out chamber 7 at any time, if temperature is too high, then can reduce heating power; If temperature is low excessively, then can strengthen heating power.
For reaching the purpose that automatic control air-out chamber 7 blows out hot blast temperature, also comprise temperature controller 6, said temperature controller 6 is electrically connected with heat-sensitive sensor 9 and power supply 15 respectively.Detect the temperature of hot blast in real time through this heat-sensitive sensor 9; Temperature controller 6 is controlled the power supply 15 as switch element through the hot blast temperature that heat-sensitive sensor 9 detects then; Reach the purpose of the electric energy input of closed or disconnection electric furnace heating wire 12, to reach the hot blast temperature that control air-out chamber 7 blows out.
