Technical field
The utility model relates to air cooling system technical field, specially a kind of air cooling system of vacuum air-quenching furnace.
Background technique
It as the vacuum drying oven of cooling medium is always vacuum drying oven major product by the inert gas that is recharged into vacuum drying oven,
The cooling performance for being widely used in the vacuum air-quenching furnaces of fields, especially heat treatment such as heat treatment, soldering, sintering is even more equipment
Key Performance Indicator.
The air cooling system of existing vacuum air-quenching furnace is to set a Room, cooling gas (generally High Purity Nitrogen together with heating room
Gas) under high pressure blower effect, heating room is circumferentially entered from heating front end or heating room by air ducting, heat is carried out to workpiece
The gas of exchange, heating is flowed out from heating rear end channel, and after carrying out heat exchange into heat exchanger, gas after cooling is again by height
Pressure fan enters next circulation, reaches cooling effect after such multiple circulations.
And the shortcomings that air cooling system of existing vacuum air-quenching furnace is: 1, workpiece is cooling just carries out in heating chamber, cold
But while workpiece, heating room heat screen and heating element are also cooled, so cooling velocity is low, cooling time is long, and energy consumption is high；
2, heating element, insulating part because rapid cooling it is (cold cracking phenomenon) easy to damage；3, for the heating element of graphite material, when because of air quenching
Air-flow, which directly washes away, causes its section to reduce even fracture, and the service life is short, and later maintenance and use cost are high；4, gas circulation path
Long, cooling effect is bad.

Furthermore, an enclosure space is constituted between the distribution of air flow cylinder, furnace body and air duct side plate.
Furthermore, the heat exchanger selects multi-stage, efficient heat exchanger.
Furthermore, several nozzles are provided on the distribution of air flow cylinder.
It is separated compared with prior art, the utility model has the beneficial effects that the system will heat room with cooling chamber, workpiece
It needs that workpiece is first moved on to cooling chamber from heating room when cooling, passes through the devices such as high pressure blower, guiding device, nozzle, heat exchanger
Workpiece is cooled down, to improve cooling velocity and cooling uniformity, and reaches raising heating room, heating element, insulating porcelain piece
Service life, reduce electric energy loss and use cost purpose.
1, cooling chamber and heating room separate, and air-flow is to the straight of heating element, insulating porcelain piece and thermal insulation layer when avoiding air quenching
It connects and washes away, extend the service life of heating element, insulating porcelain piece, thermal insulation layer.
2, cooling chamber and heating room separate, and cooling when avoiding air quenching to heating element and heating room improves cooling
Speed has saved use cost, and reducing energy consumption, (on the one hand because cooling velocity improves, the duration of runs of heavy-duty motor is reduced
And electric energy has been saved, meanwhile, workpiece heats interior still in the condition of high temperature after removing, shorten liter early period for handling next furnaceman's part
The warm time, also save electric energy).
3, distribution of air flow cylinder, furnace body, air duct side plate form an enclosure space, it is therefore prevented that by multi-stage, efficient heat exchanger
The diffusion of cooling gas and reduce wind speed, the other narrow cavity of high pressure gas arcuately, resistance is small, and kinetic energy rejection is small, cold
But speed is certainly just high.
4, the setting of distribution of air flow cylinder realizes workpiece in zonule cooling, utilizes cooling gas more effectively, improve
Cooling velocity.
5, the setting of nozzle can make cooling gas uniformly enter cooling zone, ensure that workpiece uniform decrease in temperature, improve production
Quality.
