Further, the outer wall of described vacuum tank is provided with resistance heating band, for heating to vacuum tank；In vacuum tank
Infrared radiation heating fluorescent tube is installed, for workpiece heat.
Further, described vacuum tank is additionally provided with temperature sensor, for detecting the temperature in vacuum tank.
Further, described vacuum tank is additionally provided with micro oxygen sensor, for detecting the oxygen content in vacuum tank.
Further, described vacuum pump is connected with mist filtration depurator, for filtration, purification gaseous state oils and fatss, prevents air
Pollution.
Further, described chiller is connected with oil drain pan, for recycling liquid oils and fatss.
The present invention has the effect that：
1st, increased nitrogen inlet device in degreasing plant, thus workpiece and vacuum tank can be made using gas fluidity
Ungrease treatment is more abundant；
2nd, pass through infrared radiation heating fluorescent tube to workpiece heat, the oils and fatss that can not only distil are moreover it is possible to solve in vacuum environment
Under there is no the problem of heat propagation medium；
The 3rd, temperature sensor and micro oxygen sensor are installed on the vacuum box, at any time the temperature in detection vacuum tank and oxygen
Content is it is ensured that personal safety as well as the property safety；
4th, it is provided with mist filtration depurator after vacuum pump it is ensured that the gas of exclusion does not contain gaseous state oils and fatss, thus subtracting
Few atmospheric pollution；
5th, resistance heating band is provided with the outer wall of vacuum tank, can make to be attached to the oils and fatss vaporization of vacuum chamber interior wall, from
And can prevent increasing oils and fatss from accumulating in vacuum chamber interior wall and producing blast, the person peace of operator has been effectively ensured
Entirely.

Specific embodiment
As shown in Figure 1 and Figure 2, the vacuum drying degreasing plant that the present embodiment provides includes vacuum tank 1, chiller 2, true
Empty pump 3, nitrogen inlet device 4, oil drain pan 5 and mist filtration depurator 6.
In described vacuum tank 1, multiple infrared radiation heating fluorescent tubes 11 are installed, by infrared radiation heating fluorescent tube 11 to work
Part A heats, and can make the solid grease subliming by heating being attached on workpiece A to gaseous state oils and fatss；It is provided with electricity on the outer wall of vacuum tank 1
Resistance heating tape 12, for heating to vacuum box outer wall, makes to be attached to the oils and fatss vaporization of vacuum tank 1 inwall, prevents increasing
Oils and fatss are accumulated in vacuum tank 1 inwall；Temperature sensor 7 and micro oxygen sensor 8 are additionally provided with described vacuum tank 3, by micro-
The unlatching to control infrared radiation heating fluorescent tube 11 and resistance heating band 12 for the oxygen content in amount oxygen sensor 8 detection vacuum tank,
