Description

Technical Field

[0001] This invention belongs to the technical field of material layering extraction device, and more specifically, relates to a material layering extraction device for the synthesis of cyanoethyl ester. Background Technology

[0002] Cyanoethyl ester, as an important organic synthesis intermediate and chemical raw material, is widely used in pharmaceuticals, pesticides, fragrances, and many other fields. During its production, the resulting mixture after the synthesis reaction is complex and multiphase, containing not only the target product cyanoethyl ester but also unreacted raw materials, catalyst residues, and various other impurities. To ensure the high purity of the final product—cyanoethyl ester—and meet the high standards required for subsequent applications, this mixture must undergo precise and efficient layering and extraction treatment.

[0003] Based on the above, the inventors have discovered the following problems: Currently available material separation extraction devices for cyanoethyl ester synthesis have many shortcomings. Some devices exhibit poor separation effects; the oil and water layers, due to their similar densities, are difficult to completely separate, resulting in low product purity and affecting subsequent use. Furthermore, the operation is cumbersome, requiring multiple water washes and manual agitation, which is time-consuming and inefficient.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a material layer extraction device for the synthesis of cyanoethyl ester, in order to achieve a more practical value. Utility Model Content

[0010] Furthermore, it also includes a solenoid valve, the inlet of which is connected to a first pipe, the first pipe being connected to the outlet of the pretreatment tank, the outlet of which is connected to a second pipe, the end of which is away from the solenoid valve being connected to the inlet of the centrifugal extractor, and the outlet of the centrifugal extractor being connected to a third pipe, the third pipe being connected to the inlet of the extraction tank.

[0011] Furthermore, an electric heater is installed inside the pretreatment tank.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 3 As shown:

[0029] This utility model provides a material layered extraction device for the synthesis of cyanoethyl ester, including a pretreatment tank 1, a centrifugal extractor 2, and an extraction tank 3. The pretreatment tank 1 and the extraction tank 3 are preferably cylindrical. The extraction tank 3 includes a first tank body 301, in which a stirring mechanism 302 and a spraying mechanism 303 are installed. A water outlet pipe is provided on the surface of the first tank body 301, and the water outlet pipe is located below the wire mesh on the side wall of the first tank body 301.

[0030] The stirring mechanism 302 includes a motor 30201 installed at the bottom of the first tank 301. The output end of the motor 30201 extends into the first tank 301 and connects to the stirring blades 30202. The stirring blades 30202 consist of connecting rods and blades. The connecting rods are connected to the output end of the motor 30201, and blades are mounted on the connecting rods. A pair of blades are respectively installed above and below the connecting rods, and the pair of connecting rods are arranged in a cross shape.

[0031] The spraying mechanism 303 includes an annular pipe 30301 installed on the inner wall of the first tank 301. A water inlet pipe is installed on the surface of the annular pipe 30301, extending to the outside of the first tank 301. A plurality of spray nozzles 30302 are installed on the surface of the annular pipe 30301. The annular pipe 30301 is installed above the stirring blades 30202.

[0032] The system also includes a solenoid valve 4, whose inlet is connected to a first pipe 5, which is connected to the outlet of the pretreatment tank 1. The outlet of the solenoid valve 4 is connected to a second pipe 6. The centrifugal extractor 2 has two outlets on its surface. The end of the second pipe 6 away from the solenoid valve 4 is connected to one of the inlets of the centrifugal extractor 2, and the other outlet is connected to an outlet pipe. The outlet of the centrifugal extractor 2 is connected to a third pipe 7, which is connected to the inlet of the extraction tank 3.

[0033] An electric heater 8 is installed inside the pretreatment tank 1.

[0034] It also includes a controller 9, which controls the start and stop of the electric heater 8, the centrifugal extractor 2, the solenoid valve 4, and the motor 30201.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In use, the reacted mixture is first fed into the pretreatment tank 1 via a pipeline. Then, the electric heater 8 is started and the heating time is set via the controller 9. When the preheating of the mixture in the pretreatment tank 1 is complete, the water pump and centrifugal extractor 2 can be turned on via the controller 9. The centrifugal extractor 2 draws in the mixture from the pretreatment tank 1 and separates the water layer and oil layer in the material. The separated oil layer enters the extraction tank 3 through the third pipeline 7. The water inlet pipe on the annular pipe 30301 is connected to the liquid delivery pipe in advance, and the extractant is fed into the annular pipe through the liquid delivery pipe. The liquid is drawn into the extraction tank 30301 and then sprayed out from the nozzle 30302. The water pump connected to the infusion pipeline can also be controlled by the controller 9. The controller 9 then starts the motor 30201, which drives the stirring blade 30202 to rotate, thereby mixing the liquid. After standing for a period of time, the next extraction is performed. The above steps are repeated until the predetermined extraction effect is achieved. After standing for a period of time, the water outlet pipe of the extraction tank 3 is opened to discharge the extraction residue, and then the pure oil layer containing cyanoethyl ester is discharged. This device can achieve efficient and precise stratification and extraction operations. By adopting advanced centrifugal separation technology and a multi-stage spray extraction system, the oil layer and water layer are completely separated, and impurities are fully removed, thereby significantly improving the purity and quality of cyanoethyl ester products. It solves the problems of incomplete stratification and complex operation existing in the prior art.
