The specific embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, vacuum extractor in the petroleum solvent distilling machinery, comprise: distillation case 1, by first tube connector 2 and the distillate cooler 3 that is connected of distillation case 1, vavuum pump 4, the liquid separator 6 that is connected with vavuum pump 4 by second tube connector 5, liquid separator 6 is connected with drain pipe 7, at described distillate cooler 3, be provided with injection apparatus 8 between vavuum pump 4 and the liquid separator 6, described injection apparatus 8 is by valve body 81, be arranged on the atmospheric pressure cavity 82 of valve body 81 inside, first import 83 that is arranged on atmospheric pressure cavity 82 1 sides and is connected with atmospheric pressure cavity 82, the outlet 84 that is arranged on atmospheric pressure cavity 82 upper ends and is connected with atmospheric pressure cavity 82, impeller 86 compositions that are arranged on atmospheric pressure cavity 82 lower ends and second import 85 that is connected with atmospheric pressure cavity 82 and are arranged on second import, 85 inside, distillate cooler 3 is connected with first import 83 by the 3rd tube connector 9, vavuum pump 4 is connected with second import 85 by the 4th tube connector 10, and liquid separator 6 is connected with outlet 84 by the 5th tube connector 11.
This structure operation principle be: vavuum pump 4 work, atmospheric pressure cavity 82 1 sides can form negative pressure in injection apparatus 8, the petroleum solvent of gaseous state will be drawn in the distillate cooler 3 through first tube connector 2 after distilling in the case 1 thereby will distill, the petroleum solvent of gaseous state is cooled into liquid state in distillate cooler 3, again by the 3rd tube connector 9, first import 83 enters into injection apparatus 8, again by outlet 84, the 5th tube connector 11 enters into liquid separator 6, vavuum pump 4 is drawn in the vavuum pump 4 by the petroleum solvent of second tube connector 5 with liquid separator 6 bottoms, petroleum solvent enters into second import 85 through the 4th tube connector 10 again, because thereby the impeller 86 that flows of petroleum solvent is rotated, to spray with helical form through the petroleum solvent of impeller 86, enter into the outlet 84 of atmospheric pressure cavity 82 upper ends, thereby the side at atmospheric pressure cavity 82 forms negative pressure, make the petroleum solvent that enters injection apparatus 8 from atmospheric pressure cavity 82 opposite sides enter into outlet 84 with the petroleum solvent that ejects, enter into liquid separator 6 by the 5th tube connector 11, when the petroleum solvent in the liquid separator 6 arrives the height of setting, will discharge from the drain pipe 7 that is connected with liquid separator 6.
In this process, air is sucked through liquid separator 6 by vavuum pump 4 and circulates with petroleum solvent in the distillation case 1, whole process all is in the middle of the effect that vacuumizes, two effects that vavuum pump reached are the same with being provided with, the vacuum extractor of this structure of while, simple in structure, high efficiency, low cost of manufacture.
