A thermostatic homogenizing device

Abstract

This invention provides a constant-temperature homogenizing mixing device. By forming multiple layers of turbulence-inducing depressions on the inner wall surface of a homogenizing container, each layer includes multiple turbulence-inducing depressions. Along the direction towards the bottom of the homogenizing container, the number of turbulence-inducing depressions in each layer increases, and the spacing between adjacent turbulence-inducing depressions decreases. This allows the centrifugal force generated by the stirrer to cause the liquid to flow into the turbulence-inducing depressions during homogenizing. By setting irregular spaces inside the turbulence-inducing depressions, the flow state of the liquid passing through the turbulence-inducing depressions changes, thereby avoiding the problem of low probability of fluid collision caused by the same fluid flow pattern due to the same stirring source, thus improving the mixing effect and achieving homogenizing mixing.

[0025] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention may also be implemented in other embodiments without these specific details.

[0026] It should also be understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] Furthermore, in the description of this utility model specification and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0029] This invention reveals that the reason for the poor mixing efficiency of current stirring homogenizers is that, due to the same stirring method, the liquids flow along the same path under stirring action. Therefore, the distance between liquids does not change much during stirring, resulting in a very low upper limit for the contact probability of the liquids. At this point, even if the stirring speed is increased, the improvement in the mixing effect of the liquids is not significant.

[0030] Based on this, the present invention provides a constant temperature homogenizing mixing device, such as... Figure 1 As shown, it includes: a base 1, with a heater 2 inside; a homogenizing container 6, disposed on the base 1, the distance between the heater 2 and the bottom surface of the homogenizing container 6 being the distance for heat exchange; and a stirrer, disposed inside the homogenizing container 6; wherein, the inner wall surface of the homogenizing container 6 is formed with multiple layers of turbulence-indentation recesses, each layer of turbulence-indentation recesses including multiple turbulence-indentation recesses 60, the number of turbulence-indentation recesses 60 in each layer of turbulence-indentation recesses increases along the direction toward the bottom of the homogenizing container 6, and the spacing between adjacent turbulence-indentation recesses decreases.

[0031] This invention provides a constant-temperature homogenizing mixing device. By forming multiple layers of turbulence-inducing recesses on the inner wall surface of a homogenizing container 6, each layer includes multiple turbulence-inducing recesses 60. Along the direction towards the bottom of the homogenizing container 6, the number of turbulence-inducing recesses 60 in each layer increases, and the spacing between adjacent turbulence-inducing recesses 60 decreases. During homogenization, the centrifugal force generated by the stirrer causes the liquid to flow into the turbulence-inducing recesses 60. By setting irregular spaces inside the turbulence-inducing recesses 60, the flow state of the liquid passing through the turbulence-inducing recesses 60 changes, thereby avoiding the problem of low probability of fluid collision caused by the same fluid flow pattern due to the same stirring source, thus improving the mixing effect and achieving homogenization.

[0032] The heater 2 of this invention can be a resistance heater 2, and this invention does not limit it. The homogenized container 6 and the heater 2 on the base 1 are closely attached. The distance between the two can be set to generate heat exchange, for example, the distance between the two is 1.5cm, to ensure that heat can be quickly and efficiently transferred from the heater 2 to the liquid in the homogenized container 6.

[0033] Please see Figure 2 , Figure 2 It shows Figure 1 A magnified view of part A in the middle. Figure 2 The intermediate turbulence recess layer includes a first turbulence recess layer 61, a second turbulence recess layer 62, and a third turbulence recess layer 63. Each turbulence recess layer is configured with a turbulence recess 60. In this embodiment, as an optional approach, the shape of the turbulence recess 60 can be set to various structures, such as a circular turbulence recess 60, an elliptical turbulence recess 60, or a rectangular recess. This application does not limit this.

[0034] The stirrer consists of a stirring motor, a rotating rod 3, and a set of stirring blades 5. The stirring motor is mounted on top of the homogenizing container 6. The length of the rotating rod 3 is customized according to the height of the homogenizing container 6 to ensure that the set of stirring blades 5 can reach deep into the bottom of the container. The set of stirring blades 5 consists of multiple stirring blades, which are connected to each other through off-center connection nodes. The connection nodes of each blade are at different positions. In a preferred embodiment, the blades adopt an arc-shaped design, which can increase the contact area with the liquid and improve the stirring efficiency.

[0035] In actual use, the liquid to be mixed is first poured into the homogenizing container 6. Then, the desired temperature is set via the control panel on the base 1. Assuming the set temperature is 60℃, the heater 2 immediately starts working, and heat is quickly transferred to the liquid through the contact area between the base 1 and the bottom of the homogenizing container 6. At the same time, the stirring motor is started, and the motor drives the rotating rod 3 and the stirring blade assembly 5 to rotate at high speed. The stirring blades agitate the liquid, generating centrifugal force, and the liquid flows towards the side wall of the homogenizing container 6 under the action of centrifugal force.

[0036] When liquid flows through the turbulence-prone recesses, the irregular spatial structure inside the recesses causes a dramatic change in the liquid's flow state. Liquids entering circular, elliptical, or irregularly shaped turbulence-prone recesses experience continuous changes in flow direction, increasing the probability of collisions between liquid molecules. Throughout the mixing process, the stirrer continuously operates, constantly lifting and redistributing the liquid at the bottom and edges. Combined with the effect of the turbulence-prone recesses, this results in multi-dimensional, all-around flow of the liquid within the container, achieving rapid and uniform mixing.

[0037] Optionally, the size of the turbulence recesses 60 in each turbulence recess layer can be the same or different. In this way, when the size of the turbulence recesses 60 in each turbulence recess layer is the same, the turbulence effect on the liquid is relatively balanced when it flows through each recess area. When the size of the turbulence recesses 60 is different, the liquid will form a more complex and variable turbulence liquid molecule flow path due to the resistance difference generated by the recesses of different sizes during the flow process, which promotes more complete collision and shear between liquids.

[0038] Optionally, the depth of the two end regions of the turbulence recess is less than the depth of the central region. In this embodiment, the turbulence recess 60 is rectangular and can be configured with an inclined surface inside, meaning the depth increases from the outside to the inside, reaching its deepest point at the center. When the liquid enters the turbulence recess 60, the central region, due to its greater depth, has a stronger capacity to contain and buffer the liquid, slowing down the liquid flow rate. In contrast, the two end regions are shallower, resulting in a relatively faster liquid flow rate. This creates a velocity difference within the recess, further promoting the formation of differences in the liquid's flow rate and significantly improving mixing efficiency.

[0039] Furthermore, this application can be configured with an asymmetric structure, such as... Figure 3 As shown, the turbulence recess 60 includes a first part and a second part, wherein the first part and the second part are asymmetrically arranged, that is, the junction (deepest point) of the first part and the second part is not located in the middle position of the turbulence recess 60, which can form flow differences with different characteristics in the inlet and outlet directions, thereby further improving the mixing efficiency.

[0040] Optionally, the turbulence-causing recess layer may comprise three layers; this application does not limit this to any particular layer. For example... Figure 2 As shown, Figure 2 The intermediate turbulence recess layer includes a first turbulence recess layer 61, a second turbulence recess layer 62, and a third turbulence recess layer 63. Each turbulence recess layer is configured with a turbulence recess 60. For illustration purposes, all turbulence recesses 60 provided by this utility model are identical. However, in actual use, different turbulence recesses 60 can be configured based on the target mixing efficiency. Specifically, this utility model does not impose any limitations in this regard. Figure 2In the first turbulence depression layer 61, the turbulence depression 60 is the most numerous, followed by the second turbulence depression layer 62, and the third turbulence depression layer 63 is the least numerous. This fully takes into account the characteristic that the bottom area has the fastest stirring speed and the top area has a slower stirring speed during stirring, making the turbulence effect more uniform.

[0041] Optionally, in the same layer of turbulence depressions, the spacing between any two adjacent turbulence depressions 60 may be the same or different.

[0042] Specifically, if the spacing between adjacent turbulent depressions 60 in the same turbulent depression layer is the same, the liquid will be subjected to uniformly distributed disturbances when flowing in this layer. When the spacing between adjacent turbulent depressions 60 is different, the intensity and frequency of disturbances encountered by the liquid during the flow process will change continuously, which can generate more random and complex turbulent liquid molecule flow paths, so that the liquid can be fully mixed in the horizontal direction.

[0043] Optionally, the stirrer includes a stirring motor, a rotating rod 3 connected to the stirring motor at one end, and a stirring blade assembly 5 disposed at the other end of the rotating rod 3. The stirring blade assembly 5 extends into the homogenizing container 6 and is disposed near the bottom surface of the homogenizing container 6. The stirring blade assembly 5 includes at least two stirring blades.

[0044] Optionally, the stirring blade includes a connecting node, all stirring blades are connected through the connecting node, and the connecting node is located at a position off-center of the stirring blade.

[0045] Setting the connection node off-center from the blade center point allows for uneven distribution of centrifugal force and fluid force generated by each blade when the stirring blade rotates. This results in the blade not only producing conventional circumferential stirring during rotation but also slight oscillation and vibration due to uneven force, further enhancing the disturbance effect on the liquid. This creates a more complex turbulent liquid molecule flow path within the container, promoting mutual penetration and mixing between liquids and effectively improving the mixing quality.

[0046] Optionally, the turbulence recess layer comprises three layers, with the lowest turbulence recess layer located below the horizontal plane where the lowest point of the stirring blade group 5 is located, the middle turbulence recess layer located within the horizontal space defined by the stirring blade group 5, and the uppermost turbulence recess layer located above the horizontal plane where the highest point of the stirring blade group 5 is located. In this way, the turbulence recess layer is configured based on the flow space distribution caused by stirring, thus avoiding the waste of turbulence recess layer configuration.

[0047] Optionally, the connection point of each stirring blade is located at a different position.

[0048] Specifically, because the connection points of each stirring blade are different, the fluid forces and trajectories generated by the stirring blades during rotation are different. The fluid generated by the stirring of different blades forms an extremely complex turbulent liquid molecule flow path in the container, which can make the liquid strongly disturbed in all directions, avoid the formation of mixing dead zones, ensure that the components are uniformly mixed in a very short time, and effectively improve the mixing performance of the device.

[0049] Optionally, the distance between the heater 2 and the bottom surface of the homogenizing container 6 is less than 2cm. Of course, this utility model does not limit this, as long as they are within the heat exchange distance.

[0050] Of course, it should be noted that this utility model embodiment does not mention other shapes of turbulence recesses in detail, but it can be understood that the essence of turbulence recesses is to increase the diversity of fluid flow. Therefore, this application does not limit the specific shape of the turbulence recesses, as long as they can increase the diversity of flow.

[0051] It should be understood that the sequence number of each step in this embodiment does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of this utility model embodiment.
