Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
The equipment of low iodine number content of fatty acid in reduction grease provided in an embodiment of the present invention, as shown in Figure 1 comprising tank
Body 1 and vacuum evacuation device 2, vacuum evacuation device 2 is for vacuumizing the inside of tank body 1.Wherein, it is equipped with interlayer in tank body 1, is pressing from both sides
First chamber is formed in layer, is additionally provided with second chamber in tank body 1, second chamber is mutually indepedent with first chamber, thus in tank body 1
Interior formation two chambers.First chamber can be for the conduction oil that circulates, the interlayer by the gap shape between 1 double layers of walls of tank body
At being also possible to be formed by the coil pipe being arranged on the inside of 1 tube wall of tank body.When interlayer is formed by double layers of walls, it is located at interior
One layer of tank skin of side separates first chamber and second chamber, in order to facilitate the disengaging of conduction oil, opens up on tank skin on the outside
There is the inlet and outlet being connected to outside；When interlayer is formed by coil pipe, the inner space of coil pipe forms first chamber, tank body 1
The space being internally located at outside coil pipe forms second chamber, and the both ends of coil pipe are outer respectively to stretch in inlet and outlet of the tank body 1 as conduction oil.
It is equipped with jet 11 at the top of tank body 1, grease enters the second chamber inside tank body 1 by external delivery pump from jet 11
Interior, the bottom of tank body 1 is equipped with oil outlet 12, and oil outlet 12 is connected to second chamber.Close to the middle lower section of tank body 1 in second chamber

The equipment of low iodine number content of fatty acid is handled in the reduction grease, and treatment process includes the following steps:
Step S1 is passed through conduction oil into the interlayer of tank body, and the temperature in second chamber is made to reach 160 DEG C~260 DEG C, true with taking out
Empty device extracts vacuum to the second chamber, makes the intracorporal vacuum degree of the tank in 0.1Pa~1Pa；
Step S2 sprays grease into the tank body from jet, and grease is gasified by the tank body, and part gaseous state grease is through condensing
Pipe is discharged after being cooled to liquid by discharge port；
Low temperature conduction oil is passed through in step S3, Xiang Suoshu interlayer, another part gaseous state grease is after the liquefaction of low temperature conduction oil from out
Hydraulic fluid port discharge.
8. the method according to the description of claim 7 is characterized in that the intracorporal temperature of the second chamber is 230 in step S1
℃；The vacuum means are set to slide valve Roots's unit, and the vacuum degree control in the second chamber is in 0.1Pa.
9. the method according to the description of claim 7 is characterized in that installing rotary nozzle, institute at the nozzle opening in step S2
Grease is pumped into the rotary nozzle by the delivery pump stated outside tank body.
