Description

Technical Field

[0001] The utility model belongs to the technical field of extraction equipment, and more specifically relates to a rotary disc extraction tower. Background Art

[0002] The extraction tower, also known as the extraction tower, is a liquid-liquid mass transfer device. It extracts one or several compound components in the mixture solution with another liquid to separate, enrich and purify them. This is called the solvent extraction process. During the extraction process, a liquid solvent that is immiscible or partially miscible with the pre-separated liquid mixture is added to form a two-phase system. The different solubility of each component in the raw material liquid in the liquid solvent is utilized, and the soluble component is dissolved in the added solvent phase, thereby separating the component from the raw material liquid.

[0003] Therefore, the extraction equipment needs to be able to fully mix the two phases and quickly separate the mixed phases. However, the existing extraction equipment cannot meet the two contradictory requirements. When high-intensity stirring equipment is used to improve the mixing effect, it will cause slow or unclear stratification; and when low-intensity stirring equipment is used for mixing, although the stratification is clear and the stratification speed is fast, the extraction effect is poor.

[0041] like Figure 5-Figure 7 As shown, the sedimentation plate 71 is a circular disc-shaped structure with a through hole in the center. Specifically, the sedimentation plate 71 is formed by cutting off a portion of an elliptical disc along a line parallel to the short axis and has a through hole in the center through which the rotating shaft passes, so as to facilitate connection. The angle α between the sedimentation plate 71 and the horizontal plane is 5-10°.

[0043] Furthermore, as a preferred embodiment of the utility model, a plurality of sedimentation plates 71 can be set in the first clarification section 2. According to Stokes' theorem, theoretically, the more sedimentation plates are set, the larger the sedimentation area is, and the better the sedimentation effect of the sedimentation assembly is.

[0049] like Figure 8 As shown, the upper floating plate 81 is also a circular disc-shaped structure. Specifically, the upper floating plate 81 is formed by cutting off a portion of an elliptical disc along a line parallel to the short axis. The angle between the upper floating plate 81 and the horizontal plane is 5-10°. The arc segments of the upper floating plate 81 except the notch are all fitted and fixed on the inner wall of the second large cylindrical segment 45, and the vertical distance L2 between the notches of two adjacent upper floating plates 81 is greater than 0, thereby ensuring that the descending liquid has a smoother flow path, so that the upper floating plate 81 will not hinder the downward flow of the heavy component.

[0050] In this embodiment, Figure 5As shown, the heavy component outlet 42 is arranged on the lower side of the second large cylindrical section 45 and at the lower end of the upper floating plate 81, while the light component inlet 41 is arranged on the lower side of the second small cylindrical section 43.

[0054] Furthermore, the extraction section 3 and the upper and lower clarification sections may also be connected by welding or other methods.

[0055] Specifically, the extraction section 3 is provided with a jacket 31, which is a cylindrical structure with a diameter larger than the diameter of the extraction section 3, an axial length smaller than the height of the extraction section 3 and concentrically arranged with the extraction section 3. The upper and lower ends of the jacket 31 are connected to the outer surface of the extraction section 3, and the connection method can be connected through a cone or a ring, and the cone can withstand a slightly larger internal pressure.

When the liquid medium is introduced, the method of bottom-in and top-out is adopted, and when the gas medium is introduced, the method of top-in and bottom-out is adopted. When the liquid medium is introduced, a spiral guide plate can be set in the jacket 31 to improve the heat transfer effect.

The fixing plate 34 through hole is provided with radially distributed through holes around it as a liquid circulation channel. An annular boss 37 is provided on the inner side of the top of the extraction section 3. A second through hole 38 is provided on the annular boss 37 for fixing the upper end of the connecting rod 51 inside the extraction section 3.

[0058] like Figure 5 , Fig. 9 As shown, the stirring assembly 6 arranged on the extraction tower is a high shear stirring assembly, which improves the liquid mixing effect and ensures the two-phase stratification effect under the action of the sedimentation assembly 7 and the flotation assembly 8, with fast stratification speed and clear stratification. The stirring part of the stirring assembly 6 is arranged in each extraction chamber of the extraction section 3 to form a multi-stage extraction system.

[0059] In this embodiment, the stirring assembly 6 includes a stirring drive unit 61, a rotating shaft 62, and a plurality of paddle assemblies connected to the rotating shaft 62.

The lower end of the rotating shaft 62 is connected to the shaft sleeve 36 on the fixed plate 34. The shaft sleeve 36 can limit the shaking of the bottom of the rotating shaft 62 and reduce the swing of the rotating shaft 62, so that the rotating shaft 62 is driven to rotate by the stirring drive unit 61, thereby driving the plurality of paddle assemblies on the rotating shaft 62 to perform stirring action.

[0060] Specifically, Fig.10 , Fig.11 As shown, a plurality of blade assemblies are evenly distributed on the rotating shaft 62. The blade assembly includes a stirring blade 63 and a hub 64.

[0064] In this embodiment, a total of four connecting rods 51 are arranged in the extraction section 3, and a plurality of turntables 52 are evenly arranged along the axial direction of the connecting rod 51. The turntable 52 is a disc-shaped structure. A radially distributed through hole is arranged around the central axis hole of the turntable 52 as a channel for liquid circulation. Four connecting rod holes are symmetrically arranged on the outermost side of the turntable 52. The connecting rod 51 is inserted into the connecting rod hole of the turntable 52. The plurality of turntables 52 are parallel to each other and are fixed on the connecting rod 51 at equal intervals through fastening nuts 53 that cooperate with the connecting rod 51. The lower end of the connecting rod 51 is fixed in the peripheral through hole of the fixing plate 34, and the upper end of the connecting rod 51 is fixed in the through hole of the annular boss 37 of the extraction section 3. The plurality of turntables 52 divide the entire turntable extraction tower into a plurality of extraction sections, thereby achieving the purpose of completing multi-stage extraction in the same device.

[0065] Furthermore, the fasteners connected to the connecting rod 51 and fixing the rotating disk 52 may be connected in other ways.

[0066] The utility model provides a rotary disc extraction tower, which can fully mix the two phases through the stirring assembly 6 arranged in the extraction section, improve the sedimentation effect of the heavy component suspended in the light component through the sedimentation plate 71 arranged in the first clarification section 2, and the multi-layer sedimentation plates 71 arranged in parallel reduce the sedimentation distance of the heavy component, and can settle more tiny droplets, and the sedimentation effect is good; the floating plate 81 arranged in the second clarification section 4 can improve the floating effect of the light component suspended in the heavy component; thus, under the cooperation of the first clarification section 2, the extraction section 3, and the second clarification section 4, the mixed two phases can be quickly layered while ensuring the extraction effect, and the layering effect is good. Moreover, the turntable 52 of the turntable assembly 5 divides the entire turntable extraction tower into several extraction sections, so as to achieve multi-stage extraction in the same device.
