Abstract
The utility model relates to a device for re-extracting oil and fat from the sedimentary oil sediment of defined and hydrated crude oil. The utility model is characterized in that the device is provided with an upper and a lower batch extractors; the bottoms of the batch extractors respectively form a conical body; the top of the upper batch extractor forms an elliptical shape; a stirring fin on the upper layer of a stirrer in the upper batch extractor is a flat blade, and the lower layer is an erect type swallow-fin stirring fin. Oil and fat in the oil sediment can be effectively separated through the device, and the oil length in the treated oil sediment is reduced to more or less than 7%.
Description
The utility model relates to the food oils production unit, particularly a kind ofly carries greasy device again from the precipitation oil foot after the crude oil refining aquation.
In the production of food oils such as soybean, peanut, crude oil is through containing the 35%(wet basis approximately in the precipitation oil foot after the refining aquation) about grease.Adopting rational process unit, reclaim the grease in the oil foot, is the effective way of excavating oil sources, increasing the benefit.
Existing oily factory mostly adopts oil foot thermal precipitation partition method, is about to oil foot that the aquation postprecipitation gets off by heating, and just its viscosity reduces, and staticly settles again, and the part grease is separated out, but the oil-containing 25%(wet basis still of the oil foot after handling like this) about.
The purpose of this utility model is the greasy process unit that will provide in a kind of oil foot of Separation and Recovery to greatest extent.
Task of the present utility model is finished by following scheme: promptly designed a kind of by last leaching tank body, leach tank body and go up to leach the oil foot that stirring drive disk assembly, axle envelope, valve and jar intravital agitator etc. of tank body form and carry the grease device down.The tank deck of going up the leaching tank body of this device is an elipse head, the jar end of batch extractor is a cone shape up and down, jar shape like this is to agitator setting in the jar and soak the mobile all very favourable of back oil foot, going up simultaneously the intravital agitator of batch extractor jar is divided into two-layer up and down, the upper strata stirring wing is a straight blade, lower floor's stirring wing is the vertical type swallow-wing, such agitator can be beaten the oil foot of going up in the batch extractor or the macrobead shape by sticky shape, stir as early as possible, to increase solvent and greasy contact area, reach the affinity that both destroys between grease molecule and the phospholipid molecule, do not destroy the affinity between phospholipid molecule and the water molecules again, phosphatide aquation precipitation in the oil foot is separated with grease, thus the purpose that grease is proposed.
Because solvent for use is inflammable, explosive, volatile in the batch extractor, must stop run, drip, leak.Axle envelope of the present utility model adopts the stuffing box tightness system, and filler is sealing effectiveness graphite asbestos packing or an oil immersion asbestos packing preferably.Valve on the tank body is not susceptible to plugging ball valve and stopcock.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is that the utility model oil foot is carried grease apparatus structure synoptic diagram again.
As shown in Figure 1, the utility model oil foot is carried the grease device again and is divided into batch extractor 17 and following batch extractor 24 two portions.The tank deck 7 of last batch extractor 13 is oval, and a jar end 9 is cones, electric motor 9 is arranged, speed reduction unit 10 and asbestos packing filler casing tightness system and head bearing 11 on the tank deck 7.Stir shaft 17 lower ends in the last batch extractor 17 are installed on the lower bearing 18, and straight blade stirring wing 14 and vertical type swallow-wing stirring wing 16 are arranged on the stir shaft 17.Oil foot import 12 and free gas outlet 8 is arranged on the tank deck 7.Hand-hole 15, fresh solvent inlet 6 and several mixing oil outlets 5 are arranged on the last leaching tank body 17.Below 19 dewatering outlet 20 is arranged at the bottom of the last batch extractor jar, fresh solvent outlet 4 and soak back oil foot outlet 21, hand-hole 15 in addition on the last batch extractor 17.The jar end 25 of following batch extractor 24 also is a cone.Have on the following batch extractor 24 and soak back oil foot inlet 23, communicate with the back oil foot outlet 21 of soaking of last batch extractor 17, also have mixing oil outlet 2 and free gas outlet 3 on the following batch extractor 24 by valve 22.
Fresh solvent added from fresh solvent inlet 6 go up batch extractor 17, actuating motor 9, will remove hydrated oil foot behind the unbound water again and add from oil foot import 12 and go up batch extractor 17.Restir stopped to stir in 10 minutes after having added oil foot, staticly settled.The separation surface of the last leaching oil foot beds of precipitation and mixing oil forms and drops to mixing oil and exports at 5 o'clock, opens mixing oil outlet 5 from top to bottom successively with interfacial decline, mixing oil is introduced evapo-separated machine isolate grease.The effect of following batch extractor 24 is identical with last batch extractor 17.At last, the oil foot after the processing can be discharged from soaking back oil foot outlet 26.
Claims (2)
1, a kind of oil foot is carried the grease device again, by leaching and leach down tank body on the last batch extractor and going up stirring drive disk assembly, axle envelope, valve and jar intravital agitator etc. that leach tank body and form, it is characterized in that:
A, the said tank deck of going up the leaching tank body are elipse head, and the upper and lower jar of end is cone shape;
B, the said upward intravital agitator of batch extractor are upper and lower two-layer, and the upper strata stirring wing is a straight blade, and lower floor's stirring wing is the vertical type swallow-wing.
2, oil foot according to claim 1 is carried the grease device again, it is characterized in that said axle envelope is asbestos packing filler casing tightness system, and the valve on the tank body is ball valve and stopcock.
