Description
Technical field
The present invention relates to a kind of from opening and closing Anticorrosive pollution-discharge dry cleaning observation policer operation three-chamber vacuum furnace, belong to vacuum drying oven technical field.
Background technology
At present, existing vacuum drying oven includes cooling chamber and heating chamber, is separated by locellus wall between cooling chamber and heating chamber；Cooling chamber is internally provided with air quenching room and oil quenching room, and air quenching room provides source of the gas by inflation quickly cooling mechanism, and oil quenching room carries out oil quenching by oil quenching oil groove.And heating chamber includes that heating chamber platform, material frame, material frame are positioned on heating chamber platform, heating chamber is circumferentially evenly arranged with one and above adds heat pipe simultaneously, and is provided with vacuum device outside described heating chamber.Offering locellus wall on locellus wall to import and export, imported and exported by locellus wall and put in cooling chamber by material the most ready-made in heating chamber, locellus wall is imported and exported and is provided with insulated door, and insulated door passes through insulated door elevating mechanism folding, and this vacuum drying oven has the disadvantage in that
1. when oil quenching, owing to processing materials puts into oil quenching oil groove so that pasta is heated inequality, and make oil splashing, be therefore prone to accidents.
2. heating chamber heats by adding heat pipe static state, the most easily makes material be heated inequality, does not reaches preferable processing effect.
The vacuum drying oven of the most this design, the furnace wall effect of heat insulation of its heating chamber is bad, and the temperature between cooling chamber and heating chamber does not reaches the most heat insulation simultaneously, and therefore its heat radiation is serious, consumes energy higher.
The vacuum drying oven of the most this design, when material is added hot-working, needs to open heating chamber, therefore every time materiel machining time, be intended to heating chamber again evacuation and heating, waste the substantial amounts of energy, uneconomical the most not environmentally.
5., when carrying out materiel machining, this kind of heating furnace can only use artificial, thus its cost of labor is high, simultaneously because be limited to the technology of workman, is therefore adding man-hour, can not preferably be connected between each operation, and after causing processing, material defect ware is more.
The most existing this vacuum drying oven is when carrying out evacuation, when being heated or cooled due to the material in cooling chamber and heating chamber, can produce substantial amounts of dust, therefore when vacuum device carries out evacuation, easily corrode vacuum device.
7. due to existing vacuum drying oven, when material in the heating of heating chamber or cools down in cooling chamber, can produce substantial amounts of flue dust, the gas that these contain volume of smoke is exhausted directly in air, pollutes environment, thus not environmentally.
8. this kind of vacuum drying oven can not observe workpiece processing situation in heating chamber at any time, and therefore it is when processing defect ware, it is not easy to distinguishing is which link in processing is made mistakes, thus inconvenient.
9. opening the method for body of heater due to the vacuum drying oven of this design is to open manually, thus when body of heater opened by needs, owing to fire door is heavier, it is impossible to open easily, thus very inconvenient.
