Specific embodiment
As shown in Figure 1 and Figure 2, vacuum drying degreasing plant provided in this embodiment include vacuum tank 1, it is cooling device 2, true
Sky pump 3, gas input device 4, oil drain pan 5 and clarifier 6.
Multiple infrared heating pipes 11 are installed in the vacuum tank 1, workpiece A is heated by infrared heating pipe 11, can be made
Solid grease heating sublimation on workpiece A is attached to gaseous state grease；It is provided with adding thermal resistance 12 on the outer wall of vacuum tank 1, uses
It is heated in vacuum box outer wall, makes the grease vaporization for being attached to 1 inner wall of vacuum tank, prevent more and more greases in vacuum tank 1
Inner wall accumulation；It is additionally provided with temperature sensor 7 and gas concentration detector on the vacuum tank 3, is examined by temperature sensor 7
Vacuum the temperature inside the box is surveyed to control the unlatching quantity of infrared heating pipe 11, can reach purpose that is energy saving, reducing power consumption, gas
Concentration detector can detect the gas concentration in vacuum tank 1, can determine that the oil quantity in vacuum tank 1, grease according to gas concentration
Amount is more, and gas concentration is relatively low.
The cooling device 2 includes cooler 21 and cold-trap machine 22, and cold-trap machine 22 is connect with cooler 21, for continuing
Freeze to cooler 21, so that gaseous state grease is cooled to liquid fat, vacuum tank 1 is connect by removing oil-piping with cooler 21,
Cooler 21 is connected with oil drain pan 5, is used for recovering liquid grease.
The vacuum pump 3 is connect with cooler 21, and the gaseous state grease in vacuum tank 1 is drawn to cooling by vacuum pump 3
