Description

Technical Field

[0001] The utility model relates to the field of chemical solvent production, in particular to a chemical solvent production extraction device. Background Art

[0002] Extraction is a mass transfer separation process that utilizes the difference in solubility or distribution coefficient of a compound in two immiscible or slightly soluble solvents to transfer the compound from one solvent to another to achieve component separation. Extraction can not only extract the desired substance from the liquid, but also from the solid, so it is widely used in industries such as food processing, metallurgical refining and chemical purification.

[0003] However, although the existing chemical solvent production and extraction devices can realize the extraction operation of chemical solvents, the general chemical solvent production and extraction devices only export the extracted solvent through the bottom export pipe, so that the bottom layer of extracted solvent will be exported first, and then the top layer of extracted solvent will be exported. When the bottom layer of solvent is exported, a small amount of the bottom layer of extracted solvent will remain on the inner wall of the extraction barrel. Therefore, during the process of exporting the top layer of solvent, the residual bottom layer of solvent will be integrated into the top layer of exported solvent, so that the texture of the top layer of exported solvent is not pure enough, affecting the extraction quality.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-Figure 4 A chemical solvent production extraction device is shown, comprising:

[0025] An extraction barrel 3, wherein a stirring mechanism for mixing solvents is arranged inside the extraction barrel 3, a fixing frame 5 is fixedly connected to both sides of the extraction barrel 3, a material guide pipe 9 is fixedly connected through the top of the extraction barrel 3, a guide pipe 7 is fixedly connected through the bottom of the extraction barrel 3, and a water valve 6 is fixedly connected to the surface of the guide pipe 7;

[0026] A movable plate 12 and a movable groove 10 are provided on the top of the extraction barrel 3, and the side of the movable plate 12 is slidably connected to the inner wall of the movable groove 10. A guide tube 14 is fixedly connected to one side of the movable plate 12, and a control valve 13 is fixedly connected to the surface of the guide tube 14. A sliding groove is provided on the side of the extraction barrel 3 close to the guide tube 14, and the sliding groove is connected to the movable groove 10. The side of the guide tube 14 is slidably connected to the inner wall of the sliding groove. A fixed rubber plate 11 is fixedly inserted into the inner wall of the movable groove 10, and a sealing rubber plate 18 is fixedly inserted into the inner side of the movable plate 12. The fixed rubber plate 11 and the sealing rubber plate 18 are slidably fitted with each other. By adjusting the height of the movable plate 12 and the guide tube 14, the solvent extracted in the upper layer and the solvent extracted in the lower layer can be separated and exported, thereby improving the purity of the exported solvent.

[0027] Furthermore, the stirring mechanism includes a motor 1 and a rotating shaft 15, the transmission shaft end of the motor 1 is fixedly connected to the top of the rotating shaft 15, the top end of the rotating shaft 15 passes through and is rotatably connected to the top of the extraction barrel 3, and a stirring rod 16 is fixedly connected to the side of the rotating shaft 15, which can speed up the extraction efficiency between solvents.

[0028] Furthermore, a scraper 17 is fixedly connected to the bottom of the rotating shaft 15, and the bottom of the scraper 17 is slidably connected to the bottom of the inner wall of the extraction barrel 3, so that the solvent at the bottom of the inner wall of the extraction barrel 3 can be scraped and stirred to prevent the compound from sinking to the bottom and sticking to the bottom.

[0029] Furthermore, an observation window 4 is fixedly connected to one side of the extraction barrel 3 to facilitate observation of the boundary line between the upper and lower extracted solvents, thereby adjusting the outlet height of the guide tube 14 .

[0030] Furthermore, a plug 8 is movably inserted into the inner wall of the material guide tube 9, which can increase the sealing performance in the extraction barrel 3 and improve the extraction effect.

[0031] Furthermore, both sides of the motor 1 are fixedly connected with a support frame 2, and the bottom of the support frame 2 is fixedly connected to the top of the extraction barrel 3, thereby increasing the stability of the motor 1 during operation.

[0032] Furthermore, the scraper 17 is arranged in a sloped triangular shape, so that the compounds precipitated at the bottom can be moved upward along the slope of the scraper 17, thereby assisting the compounds to be stirred and mixed again.

[0033] Through the above technical solution:

[0034] When in use, first pull the plug 8 out of the inner wall of the top of the guide tube 9, then pour the raw materials to be extracted into the extraction barrel 3 through the guide tube 9. After pouring, reinsert the plug 8 into the top of the guide tube 9, and then start the motor 1. The motor 1 drives the stirring rod 16 to perform counterclockwise stirring operation through the rotating shaft 15, so that the raw materials are mixed and extracted. The scraper 17 at the bottom of the stirring rod 16 can scrape and stir the solvent at the bottom of the inner wall of the extraction barrel 3 to prevent the compound from sinking to the bottom and sticking to the bottom. When the extracted solvent needs to be exported, the boundary layer between the upper and lower extracted solvents can be observed through the observation window 4, and then the guide tube 14 is held and the movable plate 12 is moved so that the guide tube 14 is located above the dividing line. During the sliding of the movable plate 12, the sealing rubber plate 18 on the inner side thereof and the fixed rubber plate 11 on the inner wall of the movable groove 10 can not only seal and block the solvent inside the extraction barrel 3 when the movable plate 12 slides to prevent the solvent from flowing into the movable groove 10, but also increase the friction resistance when the movable plate 12 moves. Therefore, when there is no external force pulling the movable plate 12 to move, the movable plate 12 will not actively move, thereby improving the stability of the guide tube 14 during the derivation operation. Then, the solvent in the upper layer can be derivated through the guide tube 14 by opening the control valve 13. When the upper layer solvent is derivated, the water valve 6 is opened, and the solvent in the lower layer can be derivated through the derivation pipe 7.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
