After that, it is left to stand for a period of time, and the inner cover is lifted significantly again. The turbulent discharge linkage mechanism is actuated to discharge the light liquid phase in the upper part of the inner cylinder. The light liquid phase is discharged through the flow cavity and the discharge pipe. Then, the discharge pipe at the bottom of the inner cylinder is opened to discharge the heavy liquid phase to achieve separation.

[0028] 2. The solvent inlet assembly is connected to the feed pipe for adding solvent into the feed pipe.

The rotating transmission body can drive the turbulence component to turbulently mix the raw materials inside the inner cylinder. After standing for a period of time, it can be rotated significantly again to discharge the light liquid phase through the discharge component to complete the separation.

The outer cover body 110 is connected to the inner cover body 210 by a connecting column 220. The outer cover body 110 is provided with a feed premixing mechanism 400 whose lower end extends to the interior of the inner cylinder 200. The interior of the inner cylinder 200 is provided with a turbulent discharge linkage mechanism 500. The bottoms of the outer cylinder 100 and the inner cylinder 200 are both provided with a discharge pipe 130, and the discharge pipe 130 is provided with an electromagnetic valve. The side of the outer cylinder 100 is provided with a lifting mechanism 600 for reciprocatingly lifting the outer cover body 110.

[0037] The basic principle of this embodiment is as follows: the raw material and the solvent enter the interior of the inner cylinder 200 at the feed premixing mechanism 400. During this process, the raw material and the solvent are preliminarily mixed. The outer cover 110 is reciprocatedly lifted by the lifting mechanism 600 inside the inner cylinder 200. The outer cover 110 drives the inner cover 210 to reciprocate up and down, thereby driving the turbulent discharge linkage mechanism 500 to move first in a small amplitude to stir and fully mix the raw materials inside the inner cylinder 200, and then let it stand for a period of time, and then lift the inner cover 210 again in a large amplitude. The turbulent discharge linkage mechanism 500 can be operated to discharge the light liquid phase in the upper part of the inner cylinder 200, and the light liquid phase is discharged through the circulation cavity 300 and the discharge pipe 130. Then, the discharge pipe 130 at the lower part of the inner cylinder 200 is opened to discharge the heavy liquid phase to achieve separation.

[0039] After the sedimentation separation is completed, the light liquid phase passes through the flow cavity 140 and the flow cavity 140 and then is discharged through the discharge pipe 130 at the lower part of the outer cylinder 100, and the heavy liquid phase is discharged through the discharge pipe 130 at the lower part of the inner cylinder 200 and the flow cavity 140. The inner cover body 210 can move up and down under the drive of the outer cover body 110, thereby driving the turbulence discharge linkage mechanism 500 to operate.

[0040] The feed premixing mechanism 400 in this embodiment includes a feed pipe 410 passing through the outer cover body 110, and a solvent inlet assembly is provided on the circumferential side of the feed pipe 410.

The solvent inlet assembly is connected to the feed pipe 410 for adding solvent into the feed pipe 410.

[0042] The turbulence and discharge linkage mechanism 500 in this embodiment includes a mounting column 510 installed at the bottom of the inner cylinder 200, and the upper end of the mounting column 510 is rotatably connected to a transmission body 520 through a limiting assembly. The transmission body 520 is provided with a turbulence assembly and a discharge assembly, and also includes a linkage assembly that drives the transmission body 520 to rotate.

[0043] The transmission body 520 can rotate under the drive of the linkage component. The rotating transmission body 520 can drive the turbulence component to turbulently mix the raw materials inside the inner cylinder 200. After standing for a period of time, it can rotate significantly again to discharge the light liquid phase through the discharge component.

[0044] The limiting assembly includes two limiting plates 530 arranged at the upper end of the mounting column 510, and the transmission body 520 is rotatably set on the mounting column 510 between the two limiting plates 530, which can limit the transmission body 520 to rotate on the mounting column 510 between the two limiting plates 530 to prevent it from moving up and down.

[0045] Specifically, the transmission body 520 is cylindrical, and the spoiler assembly includes a plurality of spoilers 540 disposed on the periphery of the transmission body 520 . The spoilers 540 can perform turbulent mixing on the raw materials inside the inner cylinder 200 .

[0046] The discharge assembly includes a discharge area 550 arranged on the inner cylinder 200, and a plurality of discharge holes 551 are provided on the side wall of the inner cylinder 200 in the discharge area 550.

[0050] A second aspect of the present embodiment provides a method for separation using the above-mentioned sedimentation separation device for producing rubber plasticizers, comprising the following steps:

[0051] The raw material is first mixed with the solvent NMP in the feed premixing mechanism 400, and then enters the inner cylinder 200. The lifting mechanism 600 reciprocates and lifts the outer cover 110 up and down by 1-10 cm to drive the turbulence discharge linkage mechanism 500 to operate. The raw material is first stirred and fully mixed, and then left to settle and separate for 1-3 hours. Then, when the lifting mechanism 600 reciprocates and lifts the outer cover 110 more than 10 cm, the upper light liquid phase can be discharged from the inner cylinder 200 and discharged through the discharge pipe 130 at the bottom of the outer cylinder 100. Then, the heavy liquid phase at the bottom of the inner cylinder 200 is discharged through the discharge pipe 130 at the bottom of the inner cylinder 200 to complete the separation.

[0052] A small rotation of the transmission body 520 means that the lifting mechanism 600 drives the outer cover body 110 to move up and down 1-10 cm. A large rotation of the transmission body 520 means that the lifting mechanism 600 drives the outer cover body 110 to move up more than 10 cm. At this time, the sealing plate 560 can leak out of the discharge hole 551. Of course, the above movement amplitude can be adjusted according to the size of the inner cylinder 200 and the outer cylinder 100.
