Description
Technical field
The present invention relates to a kind of protection against corrosion liquid formula that certainly opens and closes and purify observation monitoring three Room vacuum ovens, belong to vacuum oven technical field.
Background technology
At present, existing vacuum oven comprises cooling room and heating chamber, between cooling room and heating chamber, by locellus wall, separates; Cooling room inside is provided with gas quench chamber and oil quenching chamber, and the gas chamber of quenching provides source of the gas by inflation quick cooler structure, and oil quenching is carried out by oil quenching oil groove in oil quenching chamber.And heating chamber inside comprises heating chamber platform, material frame, material frame is positioned on heating chamber platform, and heating chamber is inner along being circumferentially evenly provided with one and above heating tube simultaneously, and described heating chamber outer setting has vacuum device.On locellus wall, offer locellus wall and import and export, by locellus wall, imported and exported ready-made material in heating chamber is put in cooling room, locellus wall is imported and exported insulated door is installed, and insulated door is by the folding of insulated door hoisting appliance, and this vacuum oven exists following shortcoming:
1. when oil quenching, because processing materials is put into oil quenching oil groove, make the pasta inequality of being heated, and oil is splashed, be therefore prone to accidents.
2. heating chamber is inner by the static heating of heating tube, therefore easily makes the material inequality of being heated, and does not reach good processing effect.
3. the vacuum oven of this design, the furnace wall effect of heat insulation of its heating chamber is bad, and the temperature between cooling room and heating chamber does not reach heat insulationly preferably simultaneously, so its heat radiation is serious, consumes energy higher.
4. the vacuum oven of this design, when material is added to hot-work, need to open heating chamber, during therefore each materiel machining, all will heating chamber again be vacuumized and be heated, and has wasted a large amount of energy, uneconomical also not environmental protection.
5. when carrying out materiel machining, this kind of process furnace can only be used artificial, thereby its cost of labor is high, simultaneously owing to being limited to workman's technology, therefore adding man-hour, between each operation, can not be connected preferably, causes processing rear material defect ware more.
6. existing this vacuum oven is when vacuumizing, and due to the heating material in cooling room and heating chamber or when cooling, can produce a large amount of dusts, therefore, when vacuum device vacuumizes, easily corrodes vacuum device.
7. due to existing vacuum oven, when material is in the heating of heating chamber or when cooling room is cooling, can produce a large amount of flue dust, the gas that these are contained to volume of smoke is directly discharged in air, has polluted environment, thereby not environmental protection.
8. this kind of vacuum oven can not be observed the processing situation of workpiece in heating chamber at any time, so it is when processing defect ware, and being not easy to distinguish is which link in processing is made mistakes, thereby inconvenient.
9. the method for opening body of heater due to the vacuum oven of this design is to open manually, thereby when needs are opened body of heater, because fire door is heavier, can not open easily, thereby very inconvenient.
