Description

Technical Field

[0001] The present application relates to the technical field of stirring and mixing equipment, and in particular to a stirring rotor, a stirring structure and a mixing equipment. Background Art

[0002] In the process of preparing beverages, different raw materials often need to be mixed to make the beverages more uniform and fuller in taste. There are usually two ways to mix existing beverages: one is gasless mixing, that is, during the mixing process, a large amount of gas is prevented from entering the raw materials to ensure the original flavor of the raw materials; the other is aeration mixing, that is, during the processing, a large amount of gas is introduced into the raw materials through a processing machine or external introduction to obtain a beverage with a richer taste.

[0003] The above two mixing methods are usually carried out using two different equipment. For example, airless mixing is usually carried out using a shaker, which achieves uniform mixing of different raw materials by shaking, while aerated mixing is usually carried out using a stirring device with a double-blade stirring rotor. When stirring the liquid, this stirring rotor will introduce a large amount of gas into the liquid to achieve mixing of gas and liquid. The two types of equipment cannot achieve functional interchangeability, so beverage shops are usually equipped with a variety of mixing equipment to meet different mixing needs, resulting in high equipment costs, large space occupation, and not conducive to cost control.

[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention.

[0040] The structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by persons familiar with this technology, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportion or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0041] The directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "middle", "longitudinal", "lateral", "horizontal", "inner", "outer", "radial", "circumferential" and the like in this specification are based on the directions or positional relationships shown in the drawings and are only for the convenience of simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0042] On the one hand, an embodiment of the utility model provides a stirring rotor, which includes:

[0043] A rotating body 1 having a rotation axis 4, the rotating body 1 being rotationally symmetrical about the rotation axis 4;

[0044] The flow guide part includes a plurality of flow channels 2 arranged on the rotating body 1, and each flow channel 2 is extended from top to bottom along the rotating body 1;

[0045] The stirring part includes a plurality of shifting structures 3 arranged along the circumference of the rotating body 1 and staggered with the plurality of flow channels 2. The shifting structures 3 are used to shift the material when the stirring rotor rotates along the rotation axis 4 so that the material generates a vortex that is in contact with or not in contact with the flow channel 2.

[0046] The stirring rotor provided in this embodiment forms a plurality of toggle structures 3 on the circumference of the rotating body 1, so that when the rotating body 1 rotates, the toggle structures 3 can be driven to revolve around the rotation axis 4 to stir the material, so that the material is subjected to eddy current and shear force, and the material is evenly mixed. In addition, when the toggle structure 3 stirs the material, a vortex is generated in the material. By controlling the rotation speed and rotation direction of the stirring rotor, the size of the generated vortex can be controlled, so that the generated vortex contacts or does not contact the flow channel 2 on the rotating body 1. Among them, when the vortex is small and does not contact the flow channel 2, the air above the material cannot penetrate the material layer and penetrate into the inside of the material, so that the material can be mixed without air; and when the vortex is large and can contact the flow channel 2, the upper end of the flow channel 2 will expose the surface of the material and contact the gas, and the gas above the material will be sucked into the flow channel 2 under the action of the negative pressure suction generated by the rotation of the rotating body 1. After entering the flow channel 2, the gas will flow downward along the flow channel 2 to the inside of the material, and then diffuse in the material to achieve ventilation mixing of the material.

[0047] When the stirring rotor is combined with the equipment, airless mixing and aerated mixing of materials can be achieved through the same equipment, thereby realizing integrated functional integration, adapting to different needs and requirements, improving the versatility of the equipment, reducing the number of equipment arrangements, saving equipment space, and reducing equipment costs.

[0048] It should be noted that, in this embodiment, the material may be a fluid material or a fluid material mixed with solid material. For example, in milk tea, the material may include fluid materials such as milk and tea and solid materials such as ice cubes and small solid ingredients.

[0049] The gas can be various gases, such as air, carbon dioxide gas, etc.

[0050] Airless mixing and aerated mixing are relative concepts. Airless mixing can be understood as the amount of gas introduced into the material is zero or less, while aerated mixing can be understood as the amount of gas introduced into the material is more.

[0051] The stirring rotor provided in the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

[0052] Figure 1Schematic diagram of a stirring rotor disclosed in at least one embodiment of the present utility model. Figure 1 The stirring rotor includes a rotating body 1, a flow guide part and a stirring part.

[0053] The rotating body 1 is the base of the stirring rotor, which is mainly used to connect the external driving parts, for example, Figure 7 The rotating body 1 can be connected to an external driving motor through a rotating shaft 5 to realize the rotational drive of the stirring rotor; and it is used to provide a basis for the arrangement or installation of the guide part and the stirring part, so that the guide part and the stirring part can be distributed on the rotating body 1 and driven by the rotating body 1 to rotate.

[0054] For details, see Figure 1 In the present embodiment, the rotating body 1 is a rotationally symmetrical structure. Specifically, the rotating body 1 has a rotation axis 4, and the rotating body 1 as a whole is rotationally symmetrical about the rotation axis 4. It should be noted that in the present embodiment, the rotation axis 4 can be understood as the central axis of the rotating body 1 when it rotates. It is a virtual axis and does not limit the structure of the rotating body 1 itself. The rotational symmetry of the rotating body 1 about the rotation axis 4 can be understood as that the rotating body 1 can coincide with the rotating body 1 in the initial position after rotating around the rotation axis 4 by a certain angle. With such a configuration, the rotating body 1 can achieve rotational balance during the rotation around the rotation axis 4, which can ensure the rotational stability of the rotating body 1 and provide a basis for the mixing rotor to stir the materials stably and evenly.

[0055] For example, in some embodiments, the rotating body 1 can be a rotating body such as a sphere, an ellipsoid, a cylinder, or a regular prism, a regular pyramid, etc. Such rotationally symmetrical structures can maintain rotational balance during rotation, providing a basis for the stirring rotor to stir the material stably and evenly. In order to reduce the damage of the rotating body 1 to the material, when the rotating body 1 is a rotating body with edges such as a regular prism, a regular pyramid, etc., a rounded chamfer can be set at its edges for transition.

[0056] For further information, see Figures 1 to 4 In this embodiment, the rotating body 1 has a variable diameter section 101, which is extended downward from the upper end of the rotating body 1, and the diameter of the trajectory circle of the variable diameter section 101 when rotating around the rotation axis 4 gradually increases or decreases from top to bottom, that is, the variable diameter section 101 of the rotating body 1 is in a shape of small at the top and large at the bottom or large at the top and small at the bottom, and the outer surface of the variable diameter section 101 is a continuous surface. In this way, the variable diameter section 101 with a gradually increasing diameter from top to bottom can make the gas introduced into the guide part flow from the small diameter end of the variable diameter section 101 to the large diameter end, and be thrown out from the largest diameter of the variable diameter section 101 to the surroundings to hit the container wall to form a vortex, strengthen the vortex, and improve the mixing effect. For example, Figure 7The schematic diagram of fluid circulation of stirring materials when the rotating body 1 is a sphere is shown as an example; the variable diameter section 101 with a larger top and a smaller bottom can guide the gas downward to the smallest diameter of the variable diameter section 101, so that the gas hits the bottom of the container to form a vortex, strengthens the axial circulation of the stirring material, and improves the ventilation and mixing effect of the material. For example, Figure 8 The schematic diagram of fluid circulation when the rotating body 1 is in a shape of being larger at the top and smaller at the bottom and stirring the material is shown as an example.

[0057] In this embodiment, the rotating body 1 having the diameter-changing section 101 may be a sphere, a cone or a table placed forward or inverted. Figure 1 The rotating body 1 is exemplarily shown to be a sphere. Figure 3 The example shows that the rotating body 1 is a table placed in a forward direction. Figure 4 The rotating body 1 is exemplarily shown as an inverted platform.

[0058] Specifically, in this embodiment, the rotating body 1 can be a truncated cone, a prism, a full sphere, a hemisphere, a semi-ellipsoid, a frustum, a cone, etc. Figure 3 and Figure 4 When the rotating body 1 is a truncated cone, a prism, a hemisphere, a semi-ellipsoid, or a cone, the rotating body 1 as a whole is a reduced diameter section 101; see Figure 1 When the rotating body 1 is a whole sphere, the upper half of the rotating body 1 is the variable diameter section 101 described in this embodiment.

[0059] For further information, see Figure 1 In this embodiment, the rotating body 1 is preferably a whole sphere, and the surface of the sphere is a smooth spherical surface. When it rotates in the material, it basically does not cause agitation to the material. The smooth spherical surface can also reduce the crushing effect on the material when the rotating body 1 contacts the material, reduce the crushing rate of the material during the mixing process, and improve the quality of the prepared beverage. Moreover, compared with a hemisphere, the lower half of the whole sphere can also be provided with a guide part and a stirring part, so as to improve the overall stirring efficiency and stirring uniformity of the stirring rotor.

[0060] In this embodiment, the guide part and the stirring part are both arranged on the rotating body 1, so that when the rotating body 1 rotates around the rotation axis 4, the guide part and the stirring part can be driven to rotate around the rotation axis 4. Figure 1 The flow guide part includes a plurality of flow channels 2 arranged on the rotating body 1, so as to introduce gas into the material through the flow channels 2 when needed, and the stirring part includes a plurality of toggle structures 3 arranged on the rotating body 1, so as to stir the material through the toggle structures 3.

[0061] See also Figure 1In one embodiment, the flow channel 2 includes flow channel grooves 201, each of which is evenly distributed along the circumferential direction of the rotating body 1, and each of the flow channel grooves 201 is extended from top to bottom along the surface contour of the rotating body 1. The circumferential direction of the rotating body 1 can be understood as the rotation direction of the rotating body 1 around the rotation axis 4. Based on this, the uniform distribution of each flow channel groove 201 along the circumferential direction of the rotating body 1 can be understood as the uniform distribution of each flow channel groove 201 along the rotation direction of the rotating body 1 around the rotation axis 4. In this way, during the rotation process, each flow channel groove 201 can evenly guide the gas to various positions of the material layer, thereby improving the uniformity of material ventilation and mixing. The up and down direction of the rotating body 1 can be understood as the axial direction where the rotation axis 4 is located. For example, Figure 1 The top of the rotating body 1 is shown as the upper part and the bottom is the lower part. Based on this, the flow channel 201 extending from the top to the bottom along the rotating body 1 can be understood as the flow channel 201 extending from the top of the rotating body 1 downward along the outer surface contour of the rotating body 1. In this way, the flow channel 201 can guide the gas introduced from the upper end of the rotating body 1 downward, so that the gas penetrates into the material layer, ensuring the ventilation and mixing effect of the material. For example, Figure 1 In the example, when the rotating body 1 is a sphere, the flow channel grooves 201 are evenly distributed along the circumferential direction of the sphere, and each flow channel groove 201 is extended from top to bottom along the spherical contour of the sphere.

[0062] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the flow channel groove 201 is formed by being recessed inward along the outer surface of the rotating body 1, that is, the flow channel groove 201 is a groove opened along the outer surface of the rotating body 1, and the parts of the rotating body 1 corresponding to both sides of each groove are structures protruding outward relative to the groove, and the protruding structure is the aforementioned toggle structure 3. In this way, the flow channel groove 201 and the toggle structure 3 can be formed on the rotating body 1 only by grooving the surface of the rotating body 1, so that the flow channel groove 201 and the toggle structure 3 are formed integrally with the rotating body 1, the structural stability is better, no welding and other operations are required, and the material cost and processing cost are reduced.

[0063] For further information, see Figure 1 , the portion where the flow channel 201 intersects with the outer surface of the rotating body 1 has a smooth transition or a rounded transition. For example, the portion where the flow channel 201 intersects with the outer surface of the rotating body 1 can be provided with an oblique chamfer for a smooth transition, or a round chamfer for a rounded transition. In this way, the sharp edges and corners at the intersection of the flow channel 201 and the outer surface of the rotating body 1 can be eliminated, making the rotating body 1 smoother or rounder as a whole, thereby reducing the crushing effect of the rotating body 1 on the material during rotation, reducing the crushing rate of the material during the mixing process, and improving the quality of the prepared beverage.

[0064] Further, the flow channel 201 is arranged obliquely, for example, see Figure 1 The flow channel 201 as a whole is tilted with the lower end tilted counterclockwise to the rotating body 1. Correspondingly, the toggle structures 3 located on both sides of the flow channel 201 are tilted in the same direction as the tilt direction of the flow channel 201. In this way, the tilted toggle structure 3 can not only improve the stirring efficiency, reduce energy consumption and noise, and extend the service life, but also enable the stirring rotor to control whether the material is ventilated and the ventilation amount by controlling the rotation speed and rotation direction. For example, Figure 1 In the stirring rotor shown, when the stirring rotor rotates clockwise, the toggle structure 3 can gather the material to the middle. At the same speed, the vortex formed by its rotation is smaller, which can reduce the ventilation volume of the material; when the stirring rotor rotates counterclockwise, the toggle structure 3 can push the material to the surroundings. At the same speed, the vortex formed by its rotation is larger, so that the gas can more easily pass into the interior of the material, and a large amount of ventilation and mixing of the material can be achieved.

[0065] For further information, see Figure 1 , Figure 3 and Figure 4 The inner wall of the flow channel groove 201 is a continuous smooth curved surface, for example, the inner wall of the flow channel groove 201 is a continuous arc surface. Such a configuration can improve the smoothness of the flow channel groove 201 and can provide a better guiding effect on materials and gas.

[0066] For further information, see Figure 1 , Figure 3 and Figure 4 , the expanded groove of the flow channel 201, that is, the opening width of the flow channel 201 gradually increases from the inside to the outside along the depth direction of the flow channel 201. Such a configuration, combined with the inner wall of the flow channel 201 being a smooth curved surface, makes it easier to throw out the material in the flow channel 201, avoids the material from clogging the flow channel 201, improves the mixing efficiency, and also facilitates the cleaning of the flow channel 201.

[0067] In this embodiment, along the extension direction of the flow channel groove 201, its width can be set to be equal or unequal. Figure 1 The embodiment in which the flow channel grooves 201 are substantially of equal width is exemplified. Figure 3 and Figure 4 The embodiment in which the flow channel 201 changes from narrow to wide or from wide to narrow is exemplified.

[0068] Based on the stirring rotor designed with the above structure, when ventilation and mixing are required, the stirring rotor is driven to rotate counterclockwise, and the speed is controlled so that a larger vortex is formed in the material, and the vortex can contact the flow channel groove 201, that is, the upper end of the flow channel groove 201 will be exposed to the surface of the material and contact the gas, and the gas above the material will be sucked into the flow channel groove 201 under the action of the negative pressure generated by the rotation of the rotating body 1. After the gas enters the flow channel groove 201, it will flow downward along the flow channel groove 201 and be thrown into the material at the maximum diameter of the variable diameter section 101, so as to achieve ventilation and mixing of the material. When airless mixing is required, the stirring rotor is driven to rotate clockwise, and the speed is controlled so that a smaller vortex is formed in the material, and the vortex does not contact the flow channel groove 201, that is, the stirring rotor does not expose the surface of the material, so that the air above the material cannot penetrate the material layer and penetrate into the interior of the material, so the stirring rotor can perform airless mixing or small-volume mixing on the material. Of course, in actual applications, driving the stirring rotor to rotate clockwise can also achieve ventilation mixing, but at the same speed, the ventilation volume of the stirring rotor rotating clockwise is not as good as the ventilation volume of the stirring rotor rotating counterclockwise. Similarly, driving the stirring rotor to rotate counterclockwise can also achieve airless mixing, but compared with the airless mixing achieved by the stirring rotor rotating clockwise, it is necessary to reduce the speed of the stirring rotor so that the material forms a smaller vortex, and the vortex does not contact the flow channel groove 201.

[0069] In other embodiments, the toggle structure 3 is protrudingly disposed on the outer surface of the rotating body 1, so that when the rotating body 1 rotates, the toggle structure 3 protruding from the outer surface of the rotating body 1 can toggle the material and form turbulence and vortex, driving the material to flow and mix. Figure 2 The toggle structure 3 is a convex strip extending from top to bottom along the outer surface contour of the rotating body 1. The convex strip can be set on the rotating body 1 by welding, bonding or installation, or it can be integrally formed with the rotating body 1.

[0070] Accordingly, see Figure 2 A groove is formed between two adjacent toggle structures 3 and the outer surface of the rotating body 1 located therebetween, and the groove is the flow channel 201. That is to say, the flow channel 201 is formed on the outer surface of the rotating body 1, a part of the outer surface of the rotating body 1 constitutes the bottom wall of the flow channel 201, and the side surface of the toggle structure 3 constitutes the side wall of the flow channel 201. With such a configuration, when ventilation and mixing are performed, the outer surface of the rotating body 1 can be used as a guide surface to directly introduce gas into the flow channel 201, making it easier to ventilate.

[0071] For further information, see Figure 2, the part where the toggle structure 3 intersects with the outer surface of the rotating body 1 has a smooth transition or a rounded transition. For example, the part where the toggle structure 3 intersects with the outer surface of the rotating body 1 can be provided with an oblique chamfer for a smooth transition, or a round chamfer for a smooth transition. Such a setting can make the rotating body 1 smoother as a whole, making it easier for the gas to be thrown out from the large diameter of the rotating body 1 to the surroundings, thereby improving the ventilation effect.

[0072] For further information, see Figure 2 The surface of the toggle structure 3 is a continuous smooth curved surface, for example, the surface of the toggle structure 3 is an arc-shaped surface. Such a configuration can improve the overall smoothness of the stirring rotor, reduce the breakage rate of the material during the mixing process, improve the quality of the prepared beverage, and make the flow channel 201 formed by the toggle structure 3 and the outer surface of the rotating body 1 smoother, which is convenient for guiding the gas.

[0073] Further, the toggle structure 3 is arranged to be inclined, for example, see Figure 2 The toggle structure 3 as a whole is tilted with the lower end tilted counterclockwise to the rotating body 1 , and correspondingly, the flow channel groove 201 formed between two adjacent toggle structures 3 is also tilted in the same direction.

[0074] In this embodiment, the width of the toggle structure 3 can be set to be equal or unequal. Figure 2 The embodiment in which the toggle structures 3 have substantially the same width is exemplarily shown.

[0075] Based on the above structural design, when ventilation and mixing are required, the stirring rotor is driven to rotate counterclockwise to form a larger vortex of the material. The gas above the material will enter the flow channel 201 between the two toggle structures 3, and then be thrown into the material at the maximum diameter to achieve ventilation and mixing of the material. When airless mixing is required, the stirring rotor is driven to rotate clockwise to form a smaller vortex of the material. The vortex does not contact the flow channel 201, and the air above the material cannot penetrate the material layer to penetrate into the interior of the material. Therefore, the stirring rotor can perform airless mixing or small-volume mixing of the material. Similarly, during ventilation and airless mixing, the rotation direction of the stirring rotor can also be changed, and the size of the vortex can be controlled by controlling the rotation speed.

[0076] In some embodiments, the flow channel groove 201 that is recessed on the surface of the rotating body 1 and the driving structure 3 that is raised on the surface of the rotating body 1 can also be combined. That is to say, on the basis of the flow channel groove 201 being recessed along the outer surface of the rotating body 1, the driving structure 3 is also raised on the surface of the rotating body 1 on both sides of the flow channel groove 201 (not shown), which can also realize the driving of materials and the guiding of gas.

[0077] Accordingly, in this embodiment, the inner walls and surfaces of the flow channel groove 201 and the toggle structure 3 can be set as smooth curved surfaces, and a smooth or rounded transition can be made between the two, and the two can be inclined in the same direction.

[0078] In some embodiments, the flow channel 2 may further include a flow channel hole 202, which is disposed on the rotating body 1 and penetrates the interior of the rotating body 1. For example, see Figure 5 In one example, the rotating body 1 is a structure similar to a truncated cone, the toggle structure 3 is arranged on the lower side of the rotating body 1, and the flow channel hole 202 is arranged to penetrate longitudinally from the top of the rotating body 1 to the bottom of the rotating body 1. Fig. 9 When ventilation and mixing are performed, the flow channel hole 202 can introduce gas into the bottom of the material. Compared with the flow channel groove 201, the flow channel hole 202 has more ventilation and better ventilation and mixing effect.

[0079] It should be understood that in other examples, when the rotating body 1 is spherical, conical, etc., the flow channel hole 202 can also be set on the rotating body 1. The position where the lower end of the flow channel hole 202 passes through can be set according to the mixing container, ventilation requirements, etc. For example, when the depth of the mixing container is large, the pass-through position of the flow channel hole 202 can be set at the bottom of the rotating body 1, so that the flow channel hole 202 can guide the gas to a deeper area and improve the overall ventilation uniformity of the material; for another example, when the diameter of the mixing container is large, the pass-through position of the flow channel hole 202 can be set on the outer peripheral surface of the lower part of the rotating body 1, so that the flow channel hole 202 can guide the gas to the surroundings and improve the overall ventilation uniformity of the material.

[0080] For further information, see Figure 6 In some embodiments, the rotating body 1 is provided with both a flow hole 202 and a flow groove 201. In this way, the flow hole 202 and the flow groove 201 are used to draw air together, the flow hole 202 draws the air to the bottom of the material, and the flow groove 201 draws the air to the surroundings, which can further improve the ventilation and mixing effect.

[0081] On the other hand, an embodiment of the present invention further provides a stirring structure, which includes a rotating shaft 5 and a stirring rotor of any of the above embodiments.

[0082] See also Figure 1The interior of the stirring rotor is provided with a mounting hole, and the top of the stirring rotor is provided with a mounting surface. The mounting hole is used for the coaxial fixation of the rotating shaft 5 and the stirring rotor. For example, the mounting hole is a threaded hole, and a stud matching the threaded hole is provided at the bottom of the rotating shaft 5. The coaxial fixation of the rotating shaft 5 and the stirring rotor is achieved by threaded connection to ensure that the rotating shaft 5 is coaxial with the rotation axis 4 of the stirring rotor. The mounting surface is used for axial positioning of the stirring rotor and the rotating shaft 5. For example, when the rotating shaft 5 is installed on the stirring rotor, the bottom surface of the rotating shaft 5 is arranged to fit the mounting surface of the stirring rotor.

[0083] In this embodiment, the outer peripheral surface of the rotating shaft 5 is connected to the outer peripheral surface of the rotating body 1 of the stirring rotor to form a continuous surface. Fig.10 , the diameter of the rotating shaft 5 is just equal to the diameter of the mounting surface. When the rotating shaft 5 is mounted on the mounting surface, the outer peripheral surface of the rotating shaft 5 is just connected with the surface of the rotating body 1, so that the outer peripheral surface of the rotating shaft 5 is connected with the outer peripheral surface of the rotating body 1 of the stirring rotor to form a continuous surface; for example, when the diameter of the rotating shaft 5 is smaller than the diameter of the mounting surface, when the rotating shaft 5 is mounted on the mounting surface, the outer peripheral surface of the rotating shaft 5 and the outer peripheral surface of the rotating body 1 are transitioned through an oblique chamfer or a round chamfer, so that the outer peripheral surface of the rotating shaft 5 and the outer peripheral surface of the rotating body 1 of the stirring rotor are connected to form a continuous surface. Such a setting can make the connection between the rotating shaft 5 and the stirring rotor have a smooth transition or a smooth transition. When ventilation and mixing are performed, the gas can pass through the connection between the rotating shaft 5 and the stirring rotor more smoothly and be guided into the flow channel 2 to ensure the ventilation effect.

[0084] On the other hand, an embodiment of the present invention further provides a mixing device, which includes a stirring rotor according to any of the above embodiments.
