Description

Technical Field

[0001] The utility model relates to the technical field of rotary disc extraction towers, in particular to a rotary disc extraction tower. Background Art

[0002] Extraction is one of the important unit operations for separating and purifying substances. It is a unit operation that uses the difference in solubility of each component in the mixture in an added solvent to achieve component separation. When using a turntable tower for liquid-liquid extraction, two liquids flow countercurrently in the tower, one phase of liquid is used as the dispersed phase, and passes through the other continuous phase liquid in the form of droplets. The concentrations of the two liquid phases change continuously and differentially in the equipment, and the separation of the two phases is achieved at both ends of the tower by relying on the density difference. When the light phase is used as the dispersed phase, the phase interface appears at the upper end of the tower; conversely, when the heavy phase is used as the dispersed phase, the phase interface appears at the lower end of the tower.

[0003] During the extraction operation, the turntable rotates with the central axis, and the shear stress generated in the liquid breaks the dispersed phase into many tiny droplets. The traditional approach is to increase the turntable speed and use the crushing holes on the turntable to shear the dispersed phase. Although the rupture of the dispersed phase can be accelerated by increasing the speed, the requirements for the extraction device will be higher and the cost will increase accordingly. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a rotary disc extraction tower.

[0005] According to the technical solution provided in the embodiment of the present application, a turntable extraction tower includes a tower body, a rotating rod connected through a motor output end is provided in the tower body, a plurality of turntables are provided on the rotating rod, an annular fixing plate is provided on the inner wall of the tower body between adjacent turntables, an upper disk body and a lower disk body on the turntable are fixedly connected through a plurality of dispersion columns, and crushing holes are provided on the upper disk body and the lower disk body, and when the turntable rotates, the plurality of dispersion columns and the plurality of crushing holes respectively realize contact with the liquid phase in the tower body.

[0006] Furthermore, the dispersion column is a diamond-shaped column with an arc-shaped side end surface, which reduces the resistance between the dispersion column and the liquid phase while achieving shearing of the liquid phase.

[0007] Furthermore, the crushing holes on the upper disk body and the crushing holes on the lower disk body are arranged alternately, thereby increasing the shear point between the rotating disk and the liquid phase.

[0008] Furthermore, light liquid grid plates are fixed on the inner wall of the tower body above several rotating disks and the annular fixed plate, and heavy liquid grid plates are fixed on the inner wall of the tower body below several rotating disks and the annular fixed plate, to test the filtration of liquids with different densities.

[0009] Furthermore, a heavy liquid inlet and a light liquid outlet are provided at the upper end of the tower body, and a light liquid inlet and a heavy liquid outlet are provided at the lower end of the tower body.

[0010] Furthermore, the upper disk body and the lower disk body have the same diameter, and the diameter of the upper disk body is smaller than the inner diameter of the annular fixing plate, which is convenient for installation, disassembly and maintenance.

[0011] In summary, the beneficial effects of the present application are as follows: the device of the present application sets a plurality of crushing holes and dispersion columns on the turntable of the turntable extraction tower, increases the contact points between the turntable and the dispersed phase, i.e., the liquid phase, so that when the turntable rotates, the liquid phase is sheared at multiple points, thereby increasing the shear stress of the turntable on the liquid phase, being more conducive to the rupture of the dispersed phase, thereby improving the extraction efficiency; accordingly, the impact indicators of the turntable extraction tower will not be required to be high, and its construction cost can also be reduced.

It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] A rotary disc extraction tower, such as Figure 1 , Figure 2 and Figure 3 As shown, a motor is fixedly arranged on the upper end face of a vertically arranged tower body 1, and the output end of the motor is fixedly connected to a rotating rod 2 in the tower body 1. The upper end and the lower end of the rotating rod 2 are fixedly connected to the tower body 1 through bearings. A plurality of rotating disks 3 placed from top to bottom are arranged on the rotating rod 2, and an annular fixing plate 4 is fixedly arranged on the inner wall of the tower body 1 in the gap between two adjacent rotating disks 3, and a light liquid grid plate and a heavy liquid grid plate are fixedly arranged on the inner wall of the tower body 1 above and below the rotating disk 3 and the annular fixing plate 4, respectively. A heavy liquid inlet and a light liquid inlet are arranged on the left end face of the tower body 1 from top to bottom, and a light liquid outlet is arranged above the right end thereof, and a heavy liquid outlet is arranged below;

[0022] like Figure 4 As shown, the upper disc body 31 and the lower disc body 32 on the turntable 3 are fixedly connected by a plurality of dispersion columns 33, and a plurality of crushing holes 5 are respectively arranged on the upper disc body 31 and the lower disc body 32, and the crushing holes 5 on the upper disc body 31 and the lower disc body 32 are arranged alternately;

[0023] like Figure 5 As shown, the dispersion column 33 is a diamond-shaped structure with an arc-shaped side end surface.

[0024] When in use, start the motor to rotate the turntable 3 on the rotating rod 2, and then introduce the heavy liquid and the light liquid from the heavy liquid inlet and the light liquid inlet respectively. Due to the rotation of the turntable 3, the crushing holes 5 on the upper disk body 31 and the lower disk body 32 and the dispersion column 33 will cut the liquid (i.e., heavy liquid and light liquid) in the tower body 1 during the rotation, so that the liquid is cut into small droplets, and separation and extraction are achieved based on their density difference. Then the extracted heavy liquid and light liquid are discharged from the heavy liquid outlet and the light liquid outlet respectively.
