Description

Technical Field

[0001] This utility model relates to the field of turbine extraction tower technology, specifically a turbine extraction tower rotary stirring device. Background Technology

[0002] A turbine extractor is a rotary stirred column extraction device. A series of sieve plates (stationary rings) divides the column into several stages along the axial direction. Between each pair of fixed sieve plates is a turbine mixer fixed on a rotating shaft. The rotation of the turbine in the compartment generates a characteristic flow pattern, placing the fluid inside the column in a turbulent region. The rotary stirring device in a turbine extractor is a core component of a high-efficiency liquid-liquid extraction device. The rotation of the turbine generates shear force and mixing, promoting mass transfer between the two phases (usually an aqueous phase and an organic phase).

The lower part of the upper clarification section has a heavy phase inlet distributor and a light phase outlet, while the upper part of the lower clarification section has a light phase inlet distributor and a heavy phase outlet. Multiple trays are arranged along the height of the extraction tower body within the effective section. Each tray has through holes and multiple sieve holes. The through holes are located in the center of the tray, and the sieve holes are located around the through holes. Each tray is divided into sieve plates and baffle plates, which are arranged along the height of the tray and rotate relative to it. A stirring shaft is rotatably connected to the extraction tower body, and a turbine stirring paddle is mounted on the stirring shaft. This invention aims to solve the technical problem of poor stirring and dispersion effects in existing turbine extraction tower devices due to high solution viscosity.

[0004] The aforementioned prior art is based on the same principle as the turbine extraction tower of this technical solution, but the efficiency of the internal rotary stirring needs to be improved.

[0005] The existing technology has the following technical problems: the stirring efficiency of the existing turbine extraction tower rotary stirring device needs to be improved; therefore, we propose a turbine extraction tower rotary stirring device to solve the problems mentioned above.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 The present invention provides the following technical solution:

[0033] Example 1: A turbine extraction tower rotary stirring device includes an extraction tower body 1, a bearing 2, a turntable 3 and a connecting ring 4. The bearing 2 is rotatably connected inside the extraction tower body 1. The turntable 3, a first stirring blade 5, a second stirring blade 6 and a third stirring blade 7 are fixedly connected to the outside of the bearing 2 through the connecting ring 4. Vibration sensors 9 are fixedly installed in the middle and bottom of the bearing 2. Auxiliary structures 8 are installed inside the first stirring blade 5, the second stirring blade 6 and the third stirring blade 7.

[0034] like Figures 1-3 As shown, the first stirring paddle 5 includes a first connecting plate 501 and a first blade 502. The first blade 502 with equal angles is fixedly installed on the outside of the first connecting plate 501. The first blade 502 is a vertical plate. The vertical blade, such as a slanted blade turbine or a propeller, mainly generates axial flow, which pushes the fluid in the extraction tower body 1 to circulate up and down along the bearing 2, thus avoiding local dead zones.

[0035] like Figure 1 , Figure 2 and Figure 4As shown, the second stirring paddle 6 includes a second connecting disk 601, a second blade 602, and a motor 603. The motor 603 is fixed inside the second connecting disk 601 at an equal angle. The output end of the motor 603 is fixedly connected to the second blade 602. The second blade 602 is rotatably connected to the outer side of the second connecting disk 601 at an equal angle. When the bearing 2 drives the second blade 602 to rotate longitudinally, it can drive the motor 603, so that the motor 603 drives the second blade 602 to rotate axially. Each second blade 602 can be driven by an independent motor 603 to achieve different speeds. It can also make two adjacent second blades 602 rotate in opposite directions to generate high shear turbulence. At the same time, the longitudinal rotation of the second blade 602 works in conjunction to improve the stirring efficiency.

[0036] Example 2: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the third stirring impeller 7 includes a first fixed disk 701, a first inclined impeller 702, a second fixed disk 703, and a second inclined impeller 704. The first inclined impeller 702 at an equal angle is fixed to the outside of the first fixed disk 701, and the second fixed disk 703 is fixedly installed to the outside of the first inclined impeller 702. The second inclined impeller 704 at an equal angle is fixedly connected to the outer ring of the second fixed disk 703. The first inclined impeller 702 and the second inclined impeller 704 are inclined in opposite directions. This design will generate high shear turbulence and opposing collision flow in the confluence area, thereby improving the stirring efficiency. The first inclined impeller 702 and the second inclined impeller 704 of this design can partially offset the fluid inertia and reduce ineffective circulation energy consumption.

[0037] Connecting rings 4 are fixedly connected to the inner sides of the first connecting plate 501, the second connecting plate 601, the first fixed plate 701 and the turntable 3. The connecting rings 4 are fixedly connected to the bearing 2 by screws. This design makes the turntable 3, the first stirring paddle 5, the second stirring paddle 6 and the third stirring paddle 7 easy to disassemble and assemble, so as to facilitate their maintenance and replacement.

[0038] Example 3: Figure 1 and Figures 3-6 As shown, the auxiliary structure 8 includes a temperature sensor 801 and a mechanical sensor 802. The temperature sensor 801 and the mechanical sensor 802 are respectively fixedly installed on the first blade 502, the second blade 602, the first inclined blade 702 and the second inclined blade 704, and the same sensor assembly is fixedly installed in the two opposing blade plates. The temperature sensor 801 can monitor the temperature of the blade plate to avoid local overheating of the blade plate and affect the stirring efficiency. The mechanical sensor 802 can monitor the torque and shear force of the blade plate in real time and predict mechanical failures (such as blade breakage).

[0039] like Figure 1As shown, vibration sensors 9 are fixedly installed in the middle and bottom of the bearing 2. The vibration sensors 9 can detect imbalance, bending or wear of the bearing 2 and prevent it from resonating.

[0040] Instructions for use: Use connecting ring 4 and screws to fix the turntable 3, first stirring paddle 5, second stirring paddle 6 and third stirring paddle 7 to the bearing 2. First, fix the turntable 3 at equal intervals. Then, install the first stirring paddle 5 between the first and second turntable 3, between the second and third turntable 3, between the second and third turntable 3, between the third and fourth turntable 3, and between the fourth and fifth turntable 3. The bottom of the fifth turntable 3;

[0041] A power device is connected to the top of the bearing 2. The power device is driven to make the bearing 2 rotate. At the same time, the motor 603 is driven to make the second inclined blade 704 rotate. In conjunction with the synergistic action of the first stirring blade 5, the second stirring blade 6, the third stirring blade 7 and the turntable 3, the fluid in the extraction tower body 1 is stirred, thereby improving the stirring efficiency.

[0042] The above completes a series of operations for the rotary stirring device of the turbine extraction tower. Any content not described in detail in this specification is prior art known to those skilled in the art.
