Description
Technical Field
[0001] The present invention relates to the technical field of flocculation devices, in particular to a multi-connected Taylor vortex flocculation device. Background Art
[0002] The six-in-one mixer is the main device for small-scale laboratory applications such as coagulation experiments, drug preparation, and chemical trials. It supports multiple groups of control experiments and is used in research scenarios that require multi-parameter comparison. Through the active rotation of mechanical stirring blades (such as frame, turbine, anchor, etc.), the fluid is forced to produce radial, axial, or shear flow, achieving rapid mixing of samples. However, the blades are prone to wear and have limited coverage. Local dead corners may also exist at the edges or corners of the container, resulting in insufficient mixing. The effect is poor at high viscosities, and adjustments need to be made based on the stirring time or optimized blade design.
[0003] The Taylor-Couette is a concentric cylindrical structure. When the outer cylinder is fixed and the inner cylinder rotates, regular Taylor vortex flows of varying shapes are generated in the annular gap, continuously exchanging materials within the various vortex structures. The Taylor vortex field is highly ordered, with stable and predictable vortex structures and very high reproducibility. The vortices cover the entire gap area, creating a uniform vortex field with no dead spots, resulting in extremely high mixing uniformity. This makes it particularly suitable for experiments requiring molecular-level homogenization (such as chemical synthesis and biological reactions), as well as for precision mixing, such as nanoparticle dispersion and homogenization of pharmaceutical formulations.
[0004] Global mixing is achieved through the periodic flow of Taylor vortices. The vortex cell structure promotes axial and radial fluid exchange, resulting in excellent flow stability and the absence of dead zones. This makes it particularly suitable for the stable mixing of high-viscosity media such as glycerol. Therefore, a new multi-unit Taylor vortex flocculation device was developed to address the problems existing in existing stirring / flocculation technologies, improve stirring / flocculation efficiency and treatment results, and solve the urgent technical problem of low experimental efficiency in the field of vortex control and reaction technology.

[0030] As Figs. 1-3As shown, the present application provides a multi-connected Taylor vortex flocculation device, comprising: a flocculation device body 1; a linkage rotating shaft 3 arranged at the top of the flocculation device body 1, the linkage rotating shaft 3 is provided with several groups, the linkage rotating shaft 3 comprises a rotating motor 2, a rotating shaft 3, a coupling, a bearing and a telescopic inner cylinder 4, the rotating motor 2 is arranged at the top inside of the flocculation device body 1, the output shaft of the rotating motor 2 is connected with one end of the rotating shaft 3 through the coupling, the other end of the rotating shaft 3 extends into the telescopic inner cylinder 4 and is fixedly connected with the bottom of the telescopic inner cylinder 4 through the bearing; a lifting mechanism arranged at the top and bottom inside of the flocculation device body 1, the lifting mechanism comprises a lifting plate 5, an electric lifting column 51 and a lifting table 6, one end of the electric lifting column 51 is arranged at the top of the flocculation device body 1, the other end of the electric lifting column 51 is fixedly connected with the lifting plate 5, the bottom of the lifting plate 5 is fixedly connected with the rotating motor 2, the lifting table 6 is arranged at the bottom of the flocculation device body 1, and the lifting table 6 is provided with an outer reaction cylinder clamping groove; an outer reaction cylinder 7 arranged at the bottom of the flocculation device body 1, and the outer reaction cylinder 7 is placed in the outer reaction cylinder clamping groove, and the outer reaction cylinder 7 is arranged coaxially with the telescopic inner cylinder 4, there is an annular gap between the outer reaction cylinder 7 and the telescopic inner cylinder 4, various Taylor vortices can be formed between the annular gap under the condition that the outer reaction cylinder 7 fixes the rotation of the telescopic inner cylinder 4, the number of the outer reaction cylinder 7 is the same as that of the telescopic inner cylinder 4, and the top of the outer reaction cylinder 7 is provided with a sealing cover 8.
[0031] The present application does not need mechanical paddle, and regular and different form Taylor vortex flow is generated in the reaction cylinder by the rotation of the inner cylinder, material exchange is continuously carried out in different vortex structures, and effective and uniform mixing is realized by vortex driving.
[0032] The present application can realize simultaneous stirring of liquid in different regions by the multi-group arrangement of the linkage rotating shaft 3, and the flocculation efficiency is improved. The lifting mechanism can conveniently adjust the height of the linkage rotating shaft 3, so that the outer reaction cylinder 7 and the telescopic inner cylinder 4 are separated. The design of the outer reaction cylinder 7 utilizes the principle of Taylor vortex to enhance the mixing effect of the liquid, and further improves the flocculation efficiency.
[0033] In the embodiment, the lifting mechanism is not only provided with the lifting plate 5 at the top of the flocculation device body 1, but also provided with the lifting table 6 at the bottom of the flocculation device body 1, when the reaction is completed, the lifting plate 5 controls the telescopic inner cylinder 4 to rise, the lifting table 6 controls the outer reaction cylinder 7 to descend, and the two are reversely moved to realize rapid separation.
[0034] The lifting table 6 is provided with the outer reaction cylinder clamping groove, which can not only ensure that the outer reaction cylinder 7 is stably installed on the lifting table 6, but also ensure that the outer reaction cylinder 7 is coaxially arranged with the inner cylinder. The outer reaction cylinder 7 is made of transparent material. In addition, the outer reaction cylinder 7 is placed in the outer reaction cylinder clamping groove, which is convenient for the outer reaction cylinder 7 to be freely taken out, and is convenient for replacing the reaction sample and cleaning.
[0035] In some embodiments of the present application, the linkage rotating shaft 3 further comprises an isolation sleeve 31, which is sleeved on the rotating shaft 3, one end of the isolation sleeve 31 is fixedly connected with the outer shell of the rotating motor 2, and the other end of the isolation sleeve 31 is not in contact with the outer top of the telescopic inner cylinder 4.
[0036] In this embodiment, the design of the linkage rotating shaft takes into account the need for isolation and sealing to ensure that the material during the stirring process does not contaminate the motor part, while protecting the motor from the influence of the stirred material. The isolation sleeve 31 is a key component of this design, which is sleeved on the rotating shaft 3 to form a closed space, thereby isolating the stirring area and the motor area.
[0037] One end of the isolation sleeve 31 is tightly combined with the outer shell of the rotating motor 2 through a fixed connection, which ensures that the rotating power of the motor can be effectively transmitted to the rotating shaft. Through this connection, the movement of the motor can be stably converted into the rotation of the rotating shaft, thereby realizing the mixing or stirring of the material. The other end of the isolation sleeve 31 is not in contact with the outer top of the telescopic inner cylinder 4.
[0038] It can be understood that by setting the isolation sleeve 31, the rotating shaft 3 and the outer reaction cylinder can be effectively isolated, avoiding friction or collision between the rotating shaft 3 and the sealing cover 8 of the outer reaction cylinder during rotation, thereby improving the stability and service life of the linkage rotating shaft.
[0039] In some embodiments of the present application, a plurality of connecting rods 41 are arranged inside the telescopic inner cylinder 4, one end of each connecting rod 41 is connected with the inner wall of the telescopic inner cylinder 4, and the other end of each connecting rod 41 is connected with the rotating shaft 3.
[0040] In this embodiment, a plurality of connecting rods 41 are arranged inside the telescopic inner cylinder 4, and these connecting rods 41 are uniformly distributed around the inner wall of the telescopic inner cylinder. One end of each connecting rod 41 is firmly connected with the inner wall of the telescopic inner cylinder 4, ensuring its stability. The other end of each connecting rod 41 is tightly connected with the rotating shaft 3, so that when the rotating shaft 3 rotates, the connecting rod 41 can move with it, thereby driving the telescopic inner cylinder 4 to rotate.
[0041] It can be understood that by setting the connecting rod 41, the rotating shaft 3 can be more firmly fixed inside the telescopic inner cylinder 4, preventing the telescopic inner cylinder 4 from shaking or deviating when rotating at high speed, thereby further improving the stability and stirring effect of the linkage rotating shaft. At the same time, the design of the connecting rod 41 can also make the telescopic inner cylinder 4 more stable during lifting and rotating, avoiding the influence of Taylor vortex instability caused by the imbalance of the telescopic inner cylinder 4.
[0042] In some embodiments of the present application, the sealing cover 8 includes a first sealing plate 81 and a second sealing plate 82 , one end of the first sealing plate 81 and one end of the second sealing plate 82 are hinged, and the other end of the first sealing plate 81 and the other end of the second sealing plate 82 are connected by a locking member 83 .
[0043] The first sealing plate 81 and the second sealing plate 82 are both provided with locking holes on their sides, and the locking member 83 passes through the locking hole on the first sealing plate 81 and the locking hole on the second sealing plate 82 to connect.
[0044] A semicircular groove 84 is provided in the middle of the connection between the first sealing plate 81 and the second sealing plate 82 . The circular groove formed by the combination of the semicircular grooves 84 matches the isolation sleeve 31 .
[0045] A sealing strip 85 is provided at the connection between the first sealing plate 81 and the second sealing plate 82 , and a sealing strip 85 is provided on the semicircular groove 84 . The first sealing plate and the second sealing plate cooperate with the sealing strip to seal the outer reaction tube.
[0046] It is understood that during the Taylor vortex reaction, the outer reaction tube must be sealed. The dual-plate design of the sealing cover 8, i.e., the hinged connection between the first sealing plate 81 and the second sealing plate 82 and the locking member 83, achieves a secure seal at the opening of the device. The overall structure of the sealing cover seals the outer reaction tube and prevents liquid leakage.
[0047] At the same time, the sealing effect is further improved by adding a sealing strip 85 at the connection between the first sealing plate 81 and the second sealing plate 82, and also providing a sealing strip 85 on the semicircular groove 84. This design can effectively prevent liquid leakage at the connection between the sealing plate and the isolation sleeve 31.
[0048] In some embodiments of the present application, 3-6 groups of linked rotating shafts and outer reaction cylinders are provided.
[0049] It is understandable that by setting up 3-6 groups of linked rotating shafts and external reaction cylinders, the experimental control group can be significantly increased. The simultaneous operation of multiple groups of mechanisms can simultaneously conduct multiple control experiments, saving experimental time and increasing the experimental sample size.
[0050] The device's rotating motor, electric lifting column, and lifting platform are all connected to a microcomputer controller. This intelligent and highly precise controller precisely controls parameters such as motor speed and the height of the electric lifting column. Users can customize the controller's operation by adjusting parameters such as the inner drum speed and descent height using buttons or a touchscreen interface, tailored to their experimental needs. The microcomputer controller can also be connected to other devices for automated stirring control, improving experimental efficiency and accuracy.
[0051] In this embodiment, at different inner drum rotation speeds, the Taylor vortex flow patterns within the annular gap primarily include laminar vortices, wave vortices, modulated wave vortices, and turbulent vortices. The wave vortex flow pattern produces relatively large and uniform flocs, resulting in high turbidity removal rates and excellent flocculation effects.
[0052] The rotational Reynolds number Re is defined as follows:
[0053]
[0054] In the above formula, ω is the angular velocity of the inner cylinder (rad / s), r1 is the radius of the inner cylinder (m), d = r1-r0 is the annular gap width (m), and ν is the kinematic viscosity of the fluid (1.006×10 -6 m 2 / s, the kinematic viscosity of water at 20°C). Since the relationship between the inner cylinder rotational angular velocity ω and the inner cylinder rotational speed n (r / min) is ω = 2πn, theoretically, controlling the inner cylinder rotational speed can also achieve control of the rotational Reynolds number, so the definition of the rotational Reynolds number can be rewritten as:
[0055]
[0056] When the geometric dimensions of the Taylor-Couette reactor are fixed, the rotational Reynolds number is only related to the inner drum rotation speed (equivalent to the vortex shape being only related to the inner drum rotation speed). Therefore, by controlling the inner drum rotation speed, vortex fields with different morphologies and structures can be obtained.
[0057] In this embodiment, the actual flocculation process includes a mixing stage and a flocculation stage.
[0058] Mixing stage: turbulent vortex, inner drum speed: 500r / min.
[0059] The flocculation stage includes:
[0060] The initial stage of flocculation: the late stage of wave vortex, the speed of inner drum: 45~30r / min.
[0061] Mid-stage of flocculation: flow field from the mid-stage of wave vortex to the early stage of wave vortex, inner drum speed: 30~10r / min.
[0062] Late stage of flocculation: laminar vortex, inner drum speed: 10~5r / min.
[0063] When using this device, the outer reaction cylinder is placed in the outer reaction cylinder slot at the bottom of the lifting platform to ensure that the outer reaction cylinder and the retractable inner cylinder are coaxial. The electric lifting column is controlled to lower the linkage rotating shaft so that the retractable inner cylinder enters the outer reaction cylinder. The sealing cover is covered and the target liquid sample is added. The rotating motor is started to rotate as required. Taylor vortices with controllable shape are generated in the annular gap between the inner wall of the outer reaction cylinder and the outer wall of the retractable inner cylinder. A dosing port is opened on the side wall of the outer reaction cylinder or the sealing cover. When it is necessary to add a reagent, the required reagent is added through the infusion tube, and stirring / flocculation reactions can be carried out in various vortex fields. The dosing port is sealed when not in use.
[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
