Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The device of immiscible liquid is separated as shown in figure 1, a kind of, including connects flow container 1, it is perpendicular to connect being internally provided with for flow container 1
The baffle plate 11 directly set, the both sides of the width of baffle plate 11 are separately fixed on the relative both sides inwall for connecing flow container 1, baffle plate
The both sides of 11 width and the two madial walls sealed connection for connecing flow container 1.The inner space for connecing flow container 1 is divided into by baffle plate 11
Small one and large one large space 17 and small space 16.The both sides of the length direction of baffle plate 11 are respectively facing the He of top 18 for connecing flow container 1
Bottom 19 extends and not contacted close to top 18 and bottom 19 but with top 18 and bottom 19, the both sides of the length direction of baffle plate 11
Top notch 15 and bottom notch 14 are left between top 18 and bottom 19 respectively.Top notch 15 and bottom notch 14 are distinguished
Large space 17 is connected with small space 16.
As shown in figure 1, refluxing opening 12 is arranged in the side wall for connecing flow container 1 at small space 16, inlet 13 is arranged on greatly
Top 18 at space 17.Connecing the volume size of flow container 1 and the specific installation site of baffle plate 11 needs by calculating, a liquid separation
The volume for the first solvent that needs in operating process separate should connect liquid less than the direct tube section at the Internal baffle 11 of large space 17
The volume of tank 1.The calculation formula of the setting height(from bottom) of refluxing opening 12 is：The distance of optimal setting height(from bottom) and the bottom of baffle plate 11=(the
The density of the solvent of the density of one solvent/second) 11 total length of * baffle plates.
As shown in Fig. 2 refluxing opening 12 and the inlet communication of distillation still 2, the outlet of distillation still 2 connect with the import of condenser 3
Connect, the outlet of condenser 3 connects with connecing the inlet 13 of flow container 1.Is provided with pipeline between refluxing opening 12 and distillation still 2
One bend pipe 4 and the first observation visor 5, the first bend pipe 4 are used for anti-backflow, and the first observation visor 5 is used for the situation for observing pipeline.
The second bend pipe 6 and the second observation visor 7 are provided with pipeline between condenser 3 and inlet 13, the second bend pipe 6 is used to prevent
Backflow, the second observation visor 7 are used for the situation for observing pipeline.Condenser 3 is located at distillation still 2 and connects the top of flow container 1, condenser
3 are obliquely installed, and the import of condenser 3 is higher than the outlet of condenser 3.Bottom 19 on the pipeline of valve and reservoir by setting
There is the 3rd observation visor 8.
As shown in figure 3, the lower end of the prior art for connecing flow container 1 passes through delivery pump 9 and the inlet communication of distillation still 2.It is existing
There is the operation principle in technology to be：First the first solvent and the second solvent can only be distilled into one and connect flow container 1, first is molten
Agent after connecing flow container 1 and being layered, is squeezed into the second solvent in distillation still 2 with delivery pump 9, or will connect flow container 1 and put with the second solvent
In higher position, the second solvent is divided into distillation still 2, two kinds of situations, which are intended to control, does not make the first solvent enter distillation still 2
It is interior.Due to needing, the artificial judgment page is demarcated and control valve is so continuous operation can not be realized.
The present invention comprises the following steps it is mentioned that a kind of separation method of immiscible liquid：

First solvent and with immiscible second solvent of the first solvent and solid material；
S2：The second solvent is added in flow container 1 so that the second solvent did not had bottom notch 14 just to connecing；
S3：Start and distill, in still-process, the condensed device 3 of the first solvent and the mixture of the second solvent distilled out is cold
Enter large space 17 after solidifying, after the liquid level of the second solvent in small space 16 reaches refluxing opening 12, the second solvent refluxing to steaming
Kettle 2 is evaporated, the first solvent is stayed in large space 17, that is, realizes separation.
The operation principle of the present invention：According to the volume of separation solvent, the volume size for connecing flow container 1 is calculated, before distillation,
A small amount of second solvent is added toward the inside of flow container 1 is connect, and the liquid level of the second solvent is optimal not have bottom notch 14 just.Refluxing opening
12 connect distillation still 2, and the lime set that the first solvent and the second solvent distill enters large space 17, and the first solvent and the second solvent exist
After connecing the layering of flow container 1, with the rise of liquid level, the second solvent enters distillation still 2 from the bottom of baffle plate 11 to refluxing opening 12, by first
Solvent stays in the right side of baffle plate 11.The first solvent can thus be stayed in and connect in the large space 17 of flow container 1, and the second solvent can flow back
Into distillation still 2, the first solvent is separated so as to realize, and can be operated continuously, without manual operation, only needs a cycle complete
Finish, the first solvent for connecing the inside of flow container 1 is separated.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
