The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Fig. 1 shows in the present embodiment forward Cycling hot-blast heating view in forward and reverse hot blast reciprocation cycle formula heating and drying furnace; Fig. 2 is its reverse Cycling hot-blast heating view.With reference to diagram, the present embodiment heating and drying furnace comprises body of heater 1, is provided with heating, drying chamber 2 in the body of heater 1, and workpiece 3 to be heated is placed in the heating, drying chamber 2; Also be provided with heating system and forward and reverse hot blast reciprocating circulating system in the body of heater 1, two systems link to each other and are positioned at 2 outsides, heating, drying chamber, heating system produces high-temperature hot air, by forward and reverse hot blast reciprocating circulating system high-temperature hot air is sent in the heating, drying chamber 2, treated heated parts 3 and carry out heating, drying.
For the ease of operation, heating, drying chamber 2 is arranged on body of heater 1 bottom, and heating system and forward and reverse hot blast reciprocating circulating system are arranged in the interlayer at body of heater 1 top.Heating system comprises heat exchanger 5, and forward and reverse hot blast reciprocating circulating system comprises forward and reverse circulating fan 4, is formed with air channel 6 between the two side that heating, drying chamber 2 is relative and body of heater 1 inwall, and air channel 6 is connected with forward and reverse hot blast reciprocating circulating system.Carry out heating, drying when operation treating heated parts 3, adopt the different heat source ways such as electrical heating or gas heating, improve heat exchanger 5 internal temperatures, under the effect of forward and reverse circulating fan 4, realize the heat exchange of heat exchanger 5 and outside low temperature cold air, the high-temperature hot air that produces after the heat exchange enters in the air channel 6 under the effect of forward and reverse circulating fan 4, further sends into heating, drying chamber 2.
Heating, drying chamber 2 offers equally distributed rectification hole 7 on the relative two side, rectification hole 7 is connected with air channel 6, high-temperature hot air enters heating, drying chamber 2 by rectification hole 7 by air channel 6, after treating heated parts 3 and carrying out heating, drying, the temperature meeting decrease to some degree of high-temperature hot air, the air after the cooling is discharged by a sidewall of heating, drying chamber 2, enters in the air channel 6, again heated up by forward and reverse hot blast reciprocating circulating system, successively circulation.
Circulating fan is selected forward and reverse circulating fan 4 in the present embodiment, can realize the circulation of hot blast different directions, namely shown in wind direction arrow among Fig. 1, when forward and reverse circulating fan 4 is in the forward circulation duty, high-temperature hot air after heating system heating by figure in the left air path 6 of the heating, drying chamber 2 shown in the orientation enter 2 inside, heating, drying chamber, there is again the right air path 6 of heating, drying chamber 2 to discharge heating, drying chamber 2, continues to enter heating system and heat.Shown in wind direction arrow among Fig. 2, when forward and reverse circulating fan 4 is in the recycled back duty, high-temperature hot air after heating system heating by figure in the right air path 6 of the heating, drying chamber 2 shown in the orientation enter 2 inside, heating, drying chamber, there is again the left air path 6 of heating, drying chamber 2 to discharge heating, drying chamber 2, continues to enter heating system and heat.
In the present embodiment size of rectification hole 7 be set to adjustable, can be by adjusting on 2 sidewalls of heating, drying chamber the different pore size of rectification hole 7 everywhere, with everywhere different in flow rate in the control heating furnace body, further guarantee the temperature homogeneity in the heating furnace body.
Dry when heating treating heated parts 3, can by being arranged on the control system that body of heater 1 is outside and link to each other with forward and reverse hot blast reciprocating circulating system, control forward and reverse hot blast reciprocating circulating system and carry out forward and reverse alternate cycles work.Particularly, the forward and reverse alternate cycles mode that is aligned the recycled back blower fan by control system is set, and comprises forward and reverse working time, dwell time, heat time heating time, temperature retention time etc., to tackle different workpiece and different heating, drying requirements.Correspondingly, in order to satisfy different workpieces and different heating, drying requirements, control system adopts VFC in the present embodiment, make the rotating speed of circulating fan be set to adjustable, to adjust the inlet and outlet amount of circulated air, and can be by regulating the parameters realizations such as circulating fan rotating speed, heater power to the PID process control of heating, to guarantee accuracy and the stability of control temperature in the heating furnace.
In the present embodiment, body of heater 1 is made of steel plate forming, and its skin is the thick cold-rolled steel sheet plastic-blasting of 2mm, internal layer is corrosion resistant plate, consist of skeleton by shaped steel between the inner and outer plates, the middle alumina silicate fibre insulation material of filling, this structure has insulation, heat insulation, sound insulation function aspect serviceability.Body of heater 1 bottom is also done insulation with aluminosilicate fiber cotton and is processed, and is comprised of steel structure support and cover plate, with the insulation that realizes heating, drying chamber 2, heat insulation.
When the heating and drying furnace of use present embodiment carried out heated parts, heating system and forward and reverse hot blast reciprocating circulating system started simultaneously, and heating system can adopt the different energy patterns such as electrical heating or gas heating, only needed the different heat exchanger 5 of adapted to get final product.Forward and reverse hot blast reciprocating circulating system adopts side to send side-suction type, its forward and reverse circulating fan 4 is positioned at body of heater 1 top interlayer, be designed with in the two side at body of heater 1 top give, return air chamber, forward and reverse circulating fan 4 is sent into hot blast in the heating, drying chamber 2 by plenum chamber, air channel 6 and rectification hole 7, and forms thermal current around workpiece 3 to be heated; Next be recycled to forward and reverse circulating fan 4 suction inlets by return air inlet, carry out successively circulating-heating.When the hot blast recycled back, this moment forward and reverse circulating fan 4 inverted runnings, the hot air circulation air-flow is opposite during with the hot blast forward, return air chamber when the plenum chamber during former forward circulation becomes recycled back, plenum chamber when the return air chamber during former forward circulation becomes recycled back, forward and reverse circulating fan 4 is sent into hot blast in the body of heater by plenum chamber, air channel 6 and rectification hole 7 equally.So alternately reciprocation cycle is guaranteed the heating uniformity in the heating furnace to greatest extent, to guarantee to be heated the technological requirement of workpiece.
As can be seen from the above embodiments, the embodiment of the invention is by adopting the hot air circulating system of forward and reverse alternant, simple in structure, safe and reliable, energy savings, can guarantee to greatest extent the temperature homogeneity in the heating and drying furnace, effectively utilize the inner space of whole heating and drying furnace, boost productivity.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
