DETAILED DESCRIPTION

[0020] 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.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 5 , a reaction liquid quenching and post-stratification device, comprising a stratification cylinder 1 with legs, the upper and lower ends of the stratification cylinder 1 are respectively connected with a liquid inlet pipe 104 and a liquid outlet pipe 103, a stirring rod 3 is rotatably connected in the stratification cylinder 1, a first stirring plate 301 is symmetrically fixedly connected to the stirring rod 3, a plurality of second stirring plates 302 are arranged below the first stirring plate 301, the uppermost second stirring plate 302 is in contact with the lower end of the first stirring plate 301, the stirring rod 3 is located below the first stirring plate 301 and has arc grooves symmetrically provided therein, the plurality of arc grooves gradually increase from top to bottom, a moving block 4 is slidably connected in the arc groove, the moving block 4 is fixedly connected to the adjacent second stirring plate 302, the moving block 4 is connected to the stirring rod 3 through a tension rope 401, the stirring rod 3 is located above the moving block 4 and has a slide groove provided therein, a slider 402 is slidably provided in the slide groove, the slider 402 is fixedly connected to the moving block 4, a motor 2 is arranged at the upper end of the stratification cylinder 1, and the output end of the motor 2 is fixedly connected to the stirring rod 3;

[0023] The upper end of the liquid inlet pipe 104 is hingedly connected with a cover plate 105 .

[0024] When the reaction liquid needs to be extracted and layered, the cover plate 105 is opened, and the reaction liquid and the solvent used to extract the solute are poured into the liquid inlet pipe 104 in sequence. The cover plate 105 is closed, and the reaction liquid and the solvent used to extract the solute enter the layering cylinder 1 through the liquid inlet pipe 104. The motor 2 is turned on and the stirring rod 3 rotates. At this time, under the action of the centrifugal body, the moving block 4 moves in the moving groove, so that the second stirring plate 302 moves with it until the moving block 4 and the stirring rod 3 are against each other. Due to the different lengths of the moving grooves, a gap appears between adjacent second stirring plates 302, and then the second stirring plates 302 move with the stirring rod 3. The synchronous rotation stirs the reaction liquid and the solvent used to extract the solute, and the stirring effect is better, so that the mixing is more complete. After the stirring is completed, the motor 2 stops working, and under the action of the tension rope 401, the moving block 4 moves back with the second stirring plate 302, and the first stirring plate 301 and multiple second stirring plates 302 are attached to form a baffle, so that the rotating liquid surface collides with the formed baffle, which reduces the time for the liquid surface to calm down. Compared with the existing stratification device, the moving block 4, the tension rope 401, and the second stirring plate 302 can quickly calm down the liquid surface, effectively improving the stratification rate.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 5 , a device for stratifying a reaction liquid after quenching, which is basically the same as Example 1, and further, a protrusion is provided on the second stirring plate 302, and a groove used in conjunction with the protrusion is provided on the first stirring plate 301 and the second stirring plate 302. Through the cooperation of the protrusion and the groove, the reaction liquid flows at the connection between the first stirring plate 301 and the second stirring plate 302, which affects the rate at which the liquid surface calms down.

[0027] The stirring rod 3 is symmetrically and slidably connected with a plurality of arc baffles 303, both ends of which are fixedly connected with the second stirring plate 302. When the layers are left to stand, the moving groove is shielded to prevent the reaction liquid from remaining in the moving groove.

[0028] A sealing gasket is provided on one side of the arc baffle 303 close to the stirring rod 3 to enhance the air tightness of the arc baffle 303 when shielding, thereby achieving a better shielding effect.

[0029] The stratified cylinder 1 comprises a cylinder body 101 and a cylinder cover 102. The cylinder body 101 and the cylinder cover 102 are detachably connected by threads. The motor 2 and the liquid inlet pipe 104 are both located on the cylinder cover 102. The cylinder cover 102 can be removed to facilitate cleaning of the inner wall of the cylinder body 101, the stirring rod 3, the first stirring plate 301 and the second stirring plate 302.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
