Description

Technical Field

[0001] The utility model belongs to the technical field of fine chemical industry, and specifically relates to a rapid stratified extraction device. Background Art

[0002] Extraction is a method of extracting a solute from a solution consisting of another solvent using one solvent, taking advantage of the difference in solubility of the solute in immiscible solvents. In the synthesis of pharmaceutical intermediates, after the reaction is completed and quenched, organic solvents are usually used for extraction to extract the product from the water layer as much as possible.

[0003] The operation steps of extracting and separating substances are: after adding the solvent used to extract the solute into the separatory funnel containing the solution, immediately fully shake it to allow the solute to be fully dissolved in the added solvent, then let the separatory funnel stand, wait for the liquid to separate into layers, and then separate the liquids. If the product is to be obtained, the organic solvent is distilled off to obtain the corresponding product;

[0004] When the existing extraction device is in use, a stirrer is generally used to stir the solution to transfer the solute into the added solution. However, due to the relatively simple stirring method, the solute cannot be fully transferred into the solution, thereby reducing the extraction effect. In view of this, the present utility model is specially proposed. Utility Model Content

[0012] In order to facilitate the extraction of the reaction liquid inside the extraction tank, preferably, it also includes an observation window, which is longitudinally arranged on the extraction tank and is used to observe the internal conditions of the extraction tank.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A rapid stratified extraction device comprises an extraction tank 1, on which two injection pipes 101 are symmetrically fixedly connected, and further comprises: a sleeve 3 rotatably connected in the extraction tank 1, wherein a plurality of fixed frames 301 are symmetrically fixedly connected to the sleeve 3, a rotating shaft 5 is arranged in the sleeve 3, and the rotating shaft 5 is rotatably connected to the extraction tank 1; a plurality of connecting shafts 503 rotatably connected to the fixed frames 301 at equal intervals; a paddle 302 fixedly connected to the connecting shaft 503; a transmission mechanism arranged on the connecting shaft 503, wherein the connecting shaft 503 is rotatably connected to the rotating shaft 5 through the transmission mechanism; and a driving assembly arranged on the extraction tank 1 and used for driving the sleeve 3 and the rotating shaft 5 to rotate synchronously.

[0024] The transmission mechanism includes bevel gear four 502 and bevel gear five 504. Bevel gear four 502 is fixedly connected to the rotating shaft 5. Bevel gear five 504 is fixedly connected to one end of the connecting shaft 503 passing through the sleeve 3. Bevel gear five 504 is meshedly connected with bevel gear four 502.

[0025] The driving assembly includes a motor 4, a bevel gear 1 401, a bevel gear 2 402, and a bevel gear 3 501. The motor 4 is fixedly mounted on the extraction tank 1. The bevel gear 1 401 is fixedly connected to the output end of the motor 4. The bevel gear 2 402 is fixedly connected to one end of the sleeve 3 passing through the extraction tank 1. The bevel gear 3 501 is fixedly connected to the rotating shaft 5. The bevel gear 2 402 and the bevel gear 3 501 are both meshed and connected with the bevel gear 1 401.

[0026] When in use, the staff first adds the reaction liquid used for extraction into the extraction tank 1 through the injection tube 101, and then starts the motor 4. The motor 4 is meshed and connected with the bevel gear 2 402 through the bevel gear 1 401, and then drives the sleeve 3 to rotate. At the same time, the rotating sleeve 3 drives the fixed frame 301 and the paddle 302 to rotate synchronously, so as to achieve the stirring and mixing of the reaction liquid in the extraction tank 1, and improve the extraction efficiency of the reaction liquid. At the same time, the rotating bevel gear 1 401 is meshed and connected with the bevel gear 3 501, and then drives the rotating shaft 5 to rotate. At the same time, the rotating shaft 5 is meshed and connected with the bevel gear 5 504 through the bevel gear 4 502, and then drives the connecting shaft 503 to drive the paddle 302 to rotate, so that it disturbs the reaction liquid in the extraction tank 1 to generate turbulence, so that the reaction liquid is extracted more fully, and the extraction efficiency of the reaction liquid is further improved, so as to facilitate the subsequent rapid stratification;

[0027] When the extraction of the reaction is completed, the stirring is stopped first, and then the connecting shaft 503 is driven by the driving assembly and the transmission mechanism to rotate synchronously with the rotating shaft 5. At the same time, the connecting shaft 503 drives the dial plate 302 to rotate, so that the angle of the dial plate 302 is adjusted until the dial plate 302 is adjusted to a vertical state, and then the driving assembly is turned off. At this time, the adjacent dial plates 302 are in contact and form a barrier plate in cooperation with the fixed frame 301, so that the reaction liquid flowing in the extraction tank 1 can be blocked and quickly calmed down, so that the reaction liquid after extraction can be quickly stratified, effectively improving the stratification efficiency.

[0028] Embodiment 2:

[0029] Reference Figure 1 , Figure 2 , a rapid stratified extraction device, which is basically the same as Example 1, and further, a discharge pipe 102 is fixedly connected to the bottom of the extraction tank 1, and a valve switch 103 is provided on the discharge pipe 102; when the extraction and stratification work is completed, by opening the valve switch 103 on the discharge pipe 102, the liquid can be discharged from the extraction tank 1 through the discharge pipe 102 in sequence, thereby facilitating the sequential discharge of the extracted and stratified liquid from the extraction tank 1.

[0030] The inner wall at the bottom of the extraction tank 1 is conical; when discharging liquid or material, since the inner wall at the bottom of the extraction tank 1 is conical, the liquid can gather toward the discharge pipe 102 during the discharge and discharge, so that it all flows out of the extraction tank 1, thereby preventing a small amount of reaction liquid or material from remaining in the extraction tank 1 and causing waste.

[0031] Embodiment 3:
