Description

Technical Field

[0001] The present application relates to the technical field of mixing devices, and particularly to stirring equipment.

Background Art

[0002] Stirring equipment is a simple and commonly used mixing device. The mixing device usually consists of a tank body and a stirrer deeply inserted into the tank body. The stirrer disperses the materials by stirring the materials in the tank body to achieve the mixing of the materials.

[0003] In related technologies, after the materials are put into the tank body, they flow synchronously with the stirrer. However, due to the difference in the particle size of the materials, even for the same material, the larger the particle size in the radial direction of the tank body, the greater the centrifugal force, and the farther the particles are from the central axis of the stirrer. Therefore, the closer the materials are to the central axis of the stirrer, the smaller the particle size, and the farther away from the central axis of the stirrer, the larger the particle size. As a result, the materials are stratified in the radial direction, and the mixing effect is low.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of the above problems, the present application provides a stirring device to improve the problem of radial stratification of materials and further improve the dispersion and stirring effect of materials.

[0005] To solve the above technical problems, the present application provides a stirring device. This stirring device includes a tank body, a first stirring mechanism in which a first stirring shaft is located at the central part of the tank body, and a radial flow type stirring paddle in the tank body is provided at one end of the first stirring shaft, a second stirring mechanism in which a second stirring shaft is located on one side of the first stirring shaft, the second stirring shaft and the first stirring shaft are arranged along the radial direction of the tank body, and an axial flow type stirring paddle in the tank body is provided at one end of the second stirring shaft. The stirring device further includes a flow blocking mechanism that is located in the tank body and is provided on the side wall of the tank body and is configured to block the flow of the materials in the tank body.

Advantages of the Invention

[0006] The materials in the tank body can be moved by the radial flow type stirring paddles on the first stirring shaft located at the central part of the tank body and made to flow along the radial direction of the tank body. The materials in the tank body can also be moved by the axial flow type stirring paddles on the second stirring shaft located on the side of the first stirring shaft and made to flow along the axial direction of the tank body. Thereby, the materials in the tank body flow left and right, up and down. And since the second stirring shaft of the second stirring mechanism is located on one side of the first stirring shaft of the first stirring mechanism, the materials moving up and down can be narrowed down to the other side of the first stirring shaft by the second stirring mechanism, thereby forming a circulating flow that flows left and right, up and down, and the materials in the tank body are evenly dispersed. Thereby, the problem of radial stratification of the materials is improved, and furthermore, the effects of material dispersion and stirring can be enhanced.

[0007] By providing a flow blocking mechanism in the tank body, the circulating flow that flows left and right, up and down in the tank body hits the flow blocking mechanism. After hitting the flow blocking plate, the materials scatter irregularly, the hedging movement between the materials becomes large, and the materials at each position in the tank body are evenly dispersed. Therefore, the problem of radial stratification of the materials can be further improved, and the effects of material dispersion and stirring can be further enhanced.

[0008] In some embodiments, the flow blocking mechanism includes a flow blocking plate provided on the side wall along the axial direction of the tank body.

[0009] Since the flow blocking plate is provided on the side wall of the tank body along the axial direction of the tank body, the flow blocking plate can have a blocking and dispersing effect on the materials at different depths in the tank body, thereby increasing the effects of material dispersion and stirring.

[0010] In some embodiments, the flow blocking plate is provided perpendicular to the side wall.

[0011] After the material in the tank body flows to the side wall of the tank body and then flows circumferentially along the side wall of the tank body to form a horizontal circulation flow, by providing the flow blocking plate perpendicular to the side wall of the tank body, the cross-sectional area of the flow blocking plate with respect to the material can be increased, thereby enhancing the dispersion effect of the material.

[0012] In some embodiments, the flow blocking plate is fixedly connected to the side wall.

[0013] By fixedly connecting the flow blocking plate and the side wall of the tank body, the stability between the flow blocking plate and the tank body can be improved, thereby improving the quality of the stirring equipment. The mounting structure of the flow blocking plate can be simplified, and thereby the structure of the stirring equipment can also be simplified.

[0014] In some embodiments, the flow blocking mechanism includes a plurality of flow blocking plates, and the plurality of flow blocking plates are provided symmetrically with respect to the first stirring shaft.

[0015] Since the first stirring shaft moves the material in the tank body and makes it flow along the radial direction of the tank body to form a horizontal circulation flow, by providing a plurality of flow blocking plates along the axial direction of the tank body and symmetrically with respect to the first stirring shaft on the side wall of the tank body, the dispersion and stirring effects of the material at each position in the tank body can be improved.

[0016] In some embodiments, the axial flow type stirring paddle is connected to one end located in the tank body of the two stirring shafts, and the axial direction is set parallel to the axial direction of the second stirring shaft, and includes a propeller configured to move the material in the tank body and make it flow along the axial direction.

[0017] The propeller is provided coaxially with the second stirring shaft. The propeller is driven by the second stirring shaft to rotate. When the propeller rotates, it can generate an upward or downward propelling force on the material, whereby the material in the tank body flows up and down.

[0018] In some embodiments, the second stirring mechanism includes a plurality of propellers, and the plurality of propellers are provided on the second stirring shaft at intervals along the axial direction of the second stirring shaft.

[0019] By providing the plurality of propellers coaxially with the second stirring shaft, the axial propulsive force on the material by the second stirring mechanism can be increased, and by providing the plurality of propellers at intervals, the resistance of the propellers to the material can be reduced.

[0020] In some embodiments, the radial flow type stirring paddle is connected to one end located within the tank body of the first stirring shaft, and the axial direction is set parallel to the axial direction of the first stirring shaft, and includes an anchor type stirring paddle configured to move the material within the tank body and flow it along the radial direction of the tank body.

[0021] The anchor type stirring paddle is driven by the first stirring shaft to rotate, and when the anchor paddle rotates, it can generate a radial propulsive force on the material, whereby the material within the tank body flows in the radial direction. The anchor type stirring paddle has advantages such as a wide viscosity range and low power consumption, so it is possible to expand the application range of the stirring equipment and save power consumption.

[0022] In some embodiments, the first stirring mechanism is provided on the bottom wall of the tank body, and further includes a support member configured to support one end of the first stirring shaft connected to the anchor type stirring paddle.

[0023] When the support member is fixedly provided on the bottom wall of the tank body, the first stirring shaft is connected to the anchor type stirring paddle and extends to the support member and is rotatably connected to the support member, the support member can limit the position of the first stirring shaft, and the first stirring shaft can rotate smoothly with respect to the tank body.

[0024] In some embodiments, the anchor type stirring paddle is provided near the bottom wall of the tank body and is located between the propeller and the bottom wall along the axial direction of the tank body.

[0025] Since the anchor-type stirring paddle is provided close to the bottom wall of the tank body, the anchor-type stirring paddle can move the material and make it flow along the side wall of the tank body in the radial direction of the tank body and then flow upward along the side wall. As a result, the lifted material is moved by the propeller and continues to flow upward. Since the anchor-type stirring paddle is provided far from the upper part of the tank body, the centrifugal force of the material at the upper part of the tank body is small, and the material may be pushed out to the other side of the first stirring shaft, that is, the side where the propeller is not installed. The material does not receive the action of the propeller on this side, or the received action is small, and it flows downward on the other side, thereby forming a circulating flow that flows up and down and left and right.

[0026] In some embodiments, the stirring device is provided outside the tank body and further includes a casing configured to accommodate a temperature regulator.

[0027] The casing outside the tank body can adjust the temperature of the material in the tank body with a temperature regulator such as injected cooling liquid or heating liquid, and further keep the material at an appropriate temperature all the time, thereby improving the mixing effect of the material.

[0028] Different from the prior art, the stirring device of the present application includes a tank body, a first stirring mechanism and a second stirring mechanism. The material in the tank body can be moved along the radial direction of the tank body by the radial flow type stirring paddle on the first stirring shaft located at the central part of the tank body, and the material in the tank body can also be moved along the axial direction of the tank body by the axial flow type stirring paddle on the second stirring shaft located on the side of the first stirring shaft. As a result, the material in the tank body flows left and right, up and down. Since the second stirring shaft of the second stirring mechanism is located on one side of the first stirring shaft of the first stirring mechanism, the material flowing up and down by the second stirring mechanism can be narrowed down to the other side of the first stirring shaft, thereby forming a circulating flow that flows left and right, up and down, the material in the tank body is uniformly dispersed, the problem of radial stratification is improved, and the dispersion and stirring effect of the material can be further enhanced.

[0031] The embodiments of the technical solution of the present application will be described in detail below with reference to the drawings. The following embodiments are only used as examples for more clearly explaining the technical solution of the present application, and thus cannot limit the protection scope of the present application.

[0033] The terms used in the description of this application are only for the purpose of explaining specific embodiments, and the terms "comprising" and "having" and any variations thereof in the description of this application, the claims, and the above drawings are intended to cover non-exclusive inclusion.

[0034] In the description of the embodiments of this application, technical terms such as "first" and "second" are only for distinguishing different objects, and cannot be understood as indicating relative importance, implying, or implicitly indicating the number of the indicated technical features, a specific order, a primary and secondary relationship. In the description of the embodiments of this application, "a plurality" means two or more unless otherwise defined.

[0035] The "embodiments" referred to in this specification mean that specific features, structures, or characteristics described in combination with the embodiments may be included in at least one embodiment of this application. The phrase appearing in various places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment mutually exclusive and independent of other embodiments or an alternative embodiment.

It is not for indicating or implying that the shown device or element must have a specific orientation and be constructed and operated in a specific orientation. Therefore, it should not be understood as limiting the embodiments of the present application.

[0038] In the description of the embodiments of the present application, unless otherwise clearly defined and limited, terms such as "attachment", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a removable connection, or an integral type, a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or a communication inside two elements or an interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present application according to specific situations.

[0039] A product made from a well - homogenized mixture is important for the quality of the product. For example, in the manufacturing process of a battery, first, a slurry preparation process is used. A specialized solvent and binder are respectively mixed with the powdery positive electrode active material and negative electrode active material, and after uniformly stirring, a slurry - like positive electrode material and negative electrode material are made. Then, a coating process, an assembly process, and a formation process are sequentially used to obtain a qualified finished battery. Obviously, slurry preparation is the first and important step in battery manufacturing, and the subsequent process steps of battery manufacturing can only be carried out after a qualified slurry is obtained.

[0040] When preparing a slurry, it is necessary to mix different substances in a specialized solvent and stir the slurry. Therefore, the function of the stirring equipment affects the mixing effect of the slurry, and the stirring equipment is required to achieve high efficiency, high degree of automation, reduction of labor force, good stirring effect, etc.

[0041] However, after the slurry is put into the tank body, it flows synchronously with the stirrer. Due to the difference in the particle size of the slurry, even for the same slurry, the larger the particle size of the particles in the radial direction of the tank body, the greater the centrifugal force, and the particles move farther away from the central axis of the stirring equipment. Therefore, the closer the slurry is to the central axis of the stirrer, the smaller the particle size of the particles, and the farther away from the central axis of the stirring equipment, the larger the particle size of the particles. As a result, the slurry stratifies in the radial direction and the mixing effect is low.

[0042] To solve the above problems, the present application provides a stirring device that can form a circulating flow flowing up and down and left and right in the tank body, so that the materials in the tank body are uniformly dispersed, thereby improving the problem of radial stratification of the materials, and further improving the dispersion and stirring effects of the materials.

[0043] The stirring device disclosed in the embodiments of the present application can be used in the manufacture of battery slurries to improve the performance of batteries. There are electrical devices that use this battery as a power source, or various energy storage systems that use the battery as an energy storage element. The electrical device may be, but is not limited to, a mobile phone, a tablet, a notebook computer, an electric toy, a power tool, a battery car, an electric vehicle, a ship, a spacecraft, etc. Here, the electric toy can include fixed or mobile electric toys such as a game console, an electric vehicle toy, an electric boat toy, and an electric airplane toy, and the spacecraft can include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0044] The stirring device disclosed in the embodiments of the present application can also be used for the mixing, dispersion and stirring of other materials.

[0045] This application first proposes a stirring device. As shown in FIG. 1, FIG. 1 is a schematic structural diagram of a first embodiment of the stirring device of this application. The stirring device of this embodiment includes a tank body 11, a first stirring mechanism 12 and a second stirring mechanism 13. The first stirring shaft 121 of the first stirring mechanism 12 is located at the central part of the tank body 11. At one end of the first stirring shaft 121, a radial flow type stirring paddle located in the tank body 11 is provided. The second stirring shaft 131 of the second stirring mechanism 13 is provided in the tank body 11 and is located on the side of the first stirring shaft 121 of the first stirring mechanism 12. At one end of the second stirring shaft 131, an axial flow type stirring paddle located in the tank body 11 is provided.

[0046] The second stirring shaft 131 is located on one side of the first stirring mechanism 12, and the second stirring shaft 131 and the first stirring shaft 121 are arranged along the radial direction x of the tank body 11.

[0047] The first stirring mechanism 12 is configured to move the material in the tank body 11 to flow along the radial direction x of the tank body 11. The second stirring shaft 131 of the second stirring mechanism 13 is provided in the tank body 11 and is located on the side of the first stirring shaft 121 of the first stirring mechanism 12, and is configured to move the material to flow along the axial direction y of the tank body 11.

[0048] Here, the radial flow type stirring paddle refers to a stirrer for moving the material to flow along the radial direction x of the tank body 11, and the axial flow type stirring paddle refers to a stirrer for moving the material to flow along the axial direction y of the tank body 11. The tank body 11 refers to a container for filling the material, and includes a storage cavity used for filling the material and provided with an opening, and side walls 111 and a bottom wall 112 forming this storage cavity. The central part of the tank body 11 refers to the position of the central axis of its storage cavity or a position near the central axis. The radial direction x of the tank body 11 refers to the direction perpendicular to the central axis. The axial direction y of the tank body 11 refers to the direction parallel to the central axis, that is, the depth direction of the tank body 11. The stirring mechanism refers to a member or component for moving and flowing the material. Its stirring shaft refers to the shaft body for moving and operating the stirring paddle in the stirring mechanism. The second stirring shaft 131 of the second stirring mechanism 13 is located beside the first stirring shaft 121 of the first stirring mechanism 12, which means that the second stirring shaft 131 is located between the position of the central axis of the tank body 11 or a position near the central axis and the side wall of the storage cavity.

[0049] The shape of the tank body 11 in the embodiment of the present application is not limited to shapes such as a barrel shape or a spherical shape.

[0050] The first stirring mechanism 12 in this embodiment is configured as the central stirring mechanism of the stirring device to move the material in the tank body 11 to flow along the radial direction of the tank body 11, that is, to flow left and right. The second stirring mechanism 13 is configured as the auxiliary stirring mechanism of the stirring device to move the material in the tank body 11 to flow along the axial direction of the tank body 11, that is, to flow up and down.

[0051] In this embodiment, the material in the tank body 11 can be moved by the radial flow type stirring paddle on the first stirring shaft 121 located at the central part of the tank body 11 and flowed along the radial direction of the tank body 11. The material in the tank body 11 can also be moved by the axial flow type stirring paddle on the second stirring shaft 131 located on the side of the first stirring shaft 121 and flowed along the axial direction of the tank body. Thereby, the material in the tank body 11 flows left and right, up and down. Since the second stirring shaft 131 of the second stirring mechanism 13 is located on one side of the first stirring shaft 121 of the first stirring mechanism 12, the material flowing up and down can be narrowed down to the other side of the first stirring shaft 121 by the second stirring mechanism 13. Thereby, a circulating flow flowing left and right, up and down is formed, the material in the tank body is uniformly dispersed, the problem of radial stratification is improved, and the dispersion and stirring effects of the material can be further enhanced.

[0052] In some embodiments, as shown in FIG. 2, FIG. 2 is a schematic structural view of the second embodiment of the stirring device of the present application. The stirring device of this embodiment further includes a flow blocking mechanism (see the flow blocking plate 21 in FIG. 2) located in the tank body 11 and provided on the side wall of the tank body 11, and the flow blocking mechanism is configured to block the flow of the material in the tank body.

[0053] The side wall 111 of the tank body 11 refers to the side wall of its accommodation cavity, and the flow blocking mechanism refers to a member or component for blocking the flow of the material.

[0054] In this embodiment, further, by providing a flow blocking mechanism in the tank body 11, the circulating flow flowing left and right, up and down in the tank body 11 hits the flow blocking mechanism, and the material after hitting the flow blocking plate 21 scatters irregularly, the hedging movement between the materials becomes large, and the materials at each position in the tank body 11 are uniformly dispersed. Therefore, the problem of radial stratification of the materials can be further improved, and the dispersion and mixing effects of the materials can be further enhanced.

[0055] In some embodiments, the flow blocking mechanism includes a flow blocking plate 21 provided on the side wall 111 of the tank body 11 along the axial direction of the tank body 11.

[0056] The flow blocking plate 21 being provided along the axial direction of the tank body 11 means that the flow blocking plate 21 is arranged and extends along the axial direction of the tank body 11, that is, the longitudinal direction of the flow blocking plate 21 is provided parallel to the axial direction of the tank body 11.

[0057] By providing the flow blocking plate 21 along the axial direction of the tank body 11 on the side wall 111 of the tank body 11, the flow blocking plate 21 can have a blocking and dispersing effect on the material at different depths in the tank body 11. Thereby, the effect of material dispersion and stirring is enhanced.

[0058] In some embodiments, the flow blocking plate 21 is provided perpendicular to the side wall 111 of the tank body 11.

[0059] The flow blocking plate 21 being provided perpendicular to the inner wall of the tank body 11 means that the width direction of the flow blocking plate 21 is provided perpendicular to the inner wall of the tank body.

[0060] After the material in the tank body 11 flows to the side wall 111 of the tank body 11 and then flows circumferentially along the side wall 111 of the tank body 11 to form a horizontal circulation flow, by providing the flow blocking plate 21 perpendicular to the side wall 111 of the tank body 11, the blocking cross-sectional area of the flow blocking plate 21 for the material can be increased, thereby enhancing the dispersion effect of the material.

[0061] In some embodiments, the flow blocking plate 21 is fixedly connected to the side wall 111 of the tank body 11.

[0062] The fixed connection between components refers to a non-removable connection between components after the product is shipped from the factory.

[0063] The fixed connection method between the flow blocking plate 21 and the side wall 111 of the tank body 11 in this embodiment does not necessarily have to be limited to methods such as welding connection and integral molding.

[0064] In this embodiment, by fixedly connecting the flow blocking plate 21 and the side wall 111 of the tank body 11, the stability between the flow blocking plate 21 and the tank body 11 can be improved, thereby improving the quality of the stirring device. The mounting structure of the flow blocking plate 21 can be simplified, and thereby the structure of the stirring device can also be simplified.

[0065] In some embodiments, the flow blocking mechanism of this embodiment includes a plurality of flow blocking plates 21, and the plurality of flow blocking plates 21 are provided symmetrically with respect to the first stirring shaft 121.

[0066] That the plurality of flow blocking plates 21 are provided symmetrically with respect to the first stirring shaft 121 means that they are provided axially symmetrically with the first stirring shaft 121 as the central axis.

[0067] Since the first stirring shaft 121 moves the material in the tank body 11 as the central stirring shaft of the stirring device and causes it to flow along the radial direction of the tank body 11 to form a horizontal circulation flow, by providing a plurality of flow blocking plates 21 along the axial direction of the tank body 11 and symmetrically with respect to the first stirring shaft 121 on the side wall 111 of the tank body 11, the dispersion and stirring effect of the material at each position in the tank body 11 can be improved.

[0068] In some embodiments, the flow blocking plate 21 may be provided with through holes.

[0069] By providing through holes, it is possible to prevent the material from accumulating between the flow blocking plate 21 and the tank body 11, and the blocked material can flow out from the through holes.

[0070] In some embodiments, as shown in FIG. 3, FIG. 3 is a schematic structural diagram of another embodiment of the flow blocking plate of the present application. The flow blocking plate 21 of this embodiment includes a first flow blocking portion 311 and a second flow blocking portion 312. The first flow blocking portion 311 is provided on the side wall 111 of the tank body 11 along the axial direction of the tank body 11. For the specific structure and operating principle, reference can be made to the flow blocking plate 21 in the above embodiment. The second flow blocking portion 312 is perpendicular to the first flow blocking 311 and the axial direction of the tank body 11 respectively, that is, the length of the second flow blocking portion 312 is perpendicular to the axial direction of the tank body 11, and its width direction is parallel to the radial direction of the tank body 11.

[0071] In this embodiment, by blocking the material by the first flow blocking portion 311 and the second flow blocking portion 312 having a flow blocking effect in different directions, the dispersion and stirring effect of the material at each position in the tank body 11 can be improved.

[0072] In some embodiments, as shown in FIGS. 1 and 2, the axial flow type stirring paddle is connected to one end located in the tank body 11 of the second stirring shaft 131, and the axial direction is set parallel to the axial direction of the second stirring shaft 131, and includes a propeller 132 configured to move the material in the tank body 11 and flow along the axial direction of the tank body 11.

[0073] The propeller 132 is provided coaxially with the second stirring shaft 132. The propeller 132 is driven by the second stirring shaft 131 to rotate. When the propeller 132 rotates, it can generate an upward or downward propulsive force on the material, whereby the material in the tank body 11 flows up and down.

[0074] Optionally, the second stirring mechanism 13 is provided outside the tank body 11, and further includes a second driving member 133 connected to the other end of the second stirring shaft 131 to drive the second stirring shaft 131 to rotate, thereby driving the propeller 132 to rotate.

[0075] The driving member refers to a member or component capable of generating a driving force. The second driving member 133 can realize the automatic stirring of the second stirring mechanism 13.

[0076] In some embodiments, as shown in FIG. 4, FIG. 4 is a schematic structural diagram of the third embodiment of the stirring device of the present application. The second stirring mechanism 13 of this embodiment includes a plurality of propellers 132, and the plurality of propellers 132 are provided on the second stirring shaft 131 at intervals along the axial direction of the second stirring shaft 131.

[0077] Since all of the plurality of propellers 132 of this embodiment are provided coaxially with the second stirring shaft 131, the axial propulsive force on the material by the second stirring mechanism 13 can be increased. Also, since the plurality of propellers 132 are provided at intervals, the resistance of the propellers 132 to the material can be reduced.

[0078] In some embodiments, as shown in FIGS. 1, 2, and 4, the radial flow type stirring paddle is connected to one end located in the tank body 11 of the first stirring shaft 121, and the axial direction is set parallel to the axial direction of the first stirring shaft 121, and includes an anchor type stirring paddle 122 configured to move the material in the tank body 11 and flow it along the radial direction of the tank body 11.

[0079] The anchor type stirring paddle 122 is provided coaxially with the first stirring shaft 121. The anchor type stirring paddle 122 is moved and rotated by the first stirring shaft 121. When the anchor type stirring paddle 122 rotates, it can generate a radial propulsive force on the material, whereby the material in the tank body 11 flows in the radial direction.

[0080] The anchor type stirring paddle 122 has advantages such as a wide viscosity range and low power consumption, so it is possible to expand the application range of the stirring device and save power consumption.

[0081] Optionally, the first stirring mechanism 12 is provided outside the tank body 11, and further includes a first driving member 123 that is connected to the other end of the first stirring shaft 121 to drive and rotate the first stirring shaft 121, thereby moving and rotating the anchor-type stirring paddle 122.

[0082] The first driving member 123 can realize the automatic stirring of the first stirring mechanism 12.

[0083] Optionally, the blades of the anchor-type stirring paddle 122 in this embodiment may be provided on a round anchor and a tapered anchor.

[0084] In some embodiments, instead of the anchor-type stirring paddle, a radius flow type such as a blade assembly type, a straight paddle, or a serrated disk can also be used. Instead of the propeller, a ribbon type, a screw type, a fan type, etc. can be used.

[0085] In some embodiments, as shown in FIG. 5, FIG. 5 is a schematic structural view of the fourth embodiment of the stirring device of the present application. The first stirring mechanism 12 is provided on the bottom wall 112 of the tank body 11 and further includes a support member 124 configured to support one end of the first stirring shaft 121 connected to the anchor-type stirring paddle 122.

[0086] The bottom wall 112 of the tank body 11 refers to the bottom wall of the accommodation cavity.

[0087] The support member 124 is fixedly provided on the bottom wall of the tank body 11. The first stirring shaft 121 is connected to the anchor-type stirring paddle 122 and extends to the support member 124 and is rotatably connected to the support member 124. Thereby, the support member 124 can limit the position of the first stirring shaft 121, and the first stirring shaft 121 can rotate smoothly with respect to the tank body 11.

[0088] Optionally, a restriction hole is provided on the side of the support member 124 opposite to the bottom wall of the tank body 11, and the first stirring shaft 121 is connected to the anchor-type stirring paddle 122 and embedded in the restriction hole. Alternatively, one end of the first stirring shaft 121 connected to the anchor-type stirring paddle 122 is rotatably connected to the support member 124 via an auxiliary member such as a bearing.

[0089] In some embodiments, as shown in FIGS. 1, 2, 4, and 5, the anchor-type stirring paddle 122 is provided near the bottom wall 112 of the tank body 11 and is located between the propeller 132 and the bottom wall 112 of the tank body 11 along the axial direction of the tank body 11.

[0090] When the propeller 132 rotates, it can generate an upward propulsive force on the material, so that the material at the position where the propeller 132 of the tank body 11 is provided flows upward.

[0091] Since the anchor-type stirring paddle 122 is provided near the bottom wall of the tank body 11, the anchor-type stirring paddle 122 can move the material and flow it along the radial direction of the tank body 11 to the side wall 111 of the tank body 11 and then flow upward along the side wall 111. As a result, the lifted material is moved by the propeller 132 and continues to flow upward. Since the anchor-type stirring paddle 122 is provided far from the upper part of the tank body 11, the centrifugal force of the material at the upper part of the tank body 11 is small, and the material may be pushed out to the other side of the first stirring shaft 121, that is, the side where the propeller 132 is not installed. The material does not receive the action of the propeller 132 on this side, or the received action is small, and it flows downward on the other side, thereby forming a circulating flow that moves up and down and left and right.

[0092] Of course, in other embodiments, when the driving power of the driving member is large, the anchor-type stirring paddle may be provided near the upper wall of the tank body, and along the axial direction of the tank body, the anchor-type stirring paddle is located between the propeller and the upper wall of the tank body.

[0093] Optionally, the propeller 132 includes a paddle hub and paddle blades, the paddle hub is connected to the other end of the second stirring shaft 131, and the paddle blades are connected to the outer periphery of the paddle hub.

[0094] Here, by setting the rotation direction of the propeller 132, its propulsion direction can be set.

[0095] Optionally, the propeller 132 of this embodiment can include a plurality of blades that are independent and spaced along the circumferential direction of the second stirring shaft 131, or a continuous annular blade.

[0096] In some embodiments, as shown in FIG. 6, FIG. 6 is a schematic structural diagram of the fifth embodiment of the stirring device of this application. The stirring device of this embodiment is provided outside the tank body 11 and further includes a casing 61 configured to accommodate a temperature regulator.

[0097] The casing 61 outside the tank body 11 can adjust the temperature of the material in the tank body 11 with a temperature regulator 61 such as injected coolant or heating liquid, and further keep the material at an appropriate temperature all the time, improving the mixing effect of the material.

[0098] In some embodiments, as shown in FIG. 7, the stirring device includes a tank body 11, a first stirring mechanism 12, a second stirring mechanism 13, a flow blocking plate 21, and a casing 61. The first stirring shaft 121 of the first stirring mechanism 12 is located at the central part of the tank body 11. A radial flow type stirring paddle located in the tank body 11 is provided at one end of the first stirring shaft 121. The second stirring shaft 131 of the second stirring mechanism 13 is provided in the tank body 11 and is located on the side of the first stirring shaft 121 of the first stirring mechanism 12. An axial flow type stirring paddle located in the tank body 11 is provided at one end of the second stirring shaft 131. The flow blocking plate 21 is provided on the side wall 111 of the tank body 11 along the axial direction of the tank body 11. The casing 61 is provided outside the tank body 11 and is configured to accommodate a temperature regulator.

[0099] The first stirring mechanism 12 is configured to move the material in the tank body 11 and cause it to flow along the radial direction x of the tank body 11. The second stirring shaft 131 of the second stirring mechanism 13 is provided in the tank body 11 and is located on the side of the first stirring shaft 121 of the first stirring mechanism 12, and is configured to move the material and cause it to flow along the axial direction y of the tank body 11.

[0100] In this embodiment, the material in the tank body 11 can be moved by the radial flow type stirring paddles on the first stirring shaft 121 located at the central part of the tank body 11 and caused to flow along the radial direction of the tank body 11. The material in the tank body 11 can also be moved by the axial flow type stirring paddles on the second stirring shaft 131 located on the side of the first stirring shaft 121 and caused to flow along the axial direction of the tank body. Thereby, the material in the tank body 11 flows left and right, up and down. Since the second stirring shaft 131 of the second stirring mechanism 13 is located on one side of the first stirring shaft 121 of the first stirring mechanism 12, the material flowing up and down can be narrowed down to the other side of the first stirring shaft 121 by the second stirring mechanism 13. Thereby, a circulating flow flowing left and right, up and down is formed, the material in the tank body is uniformly dispersed, the problem of radial stratification of the material is improved, and furthermore, the dispersion and mixing effect of the material can be enhanced.

[0101] Also, in this embodiment, by providing the flow blocking plate 21 in the tank body 11, the circulating flow flowing left and right, up and down in the tank body 11 hits the flow blocking plate 21, and the material after hitting the flow blocking plate 21 scatters irregularly, the hedging movement between the materials becomes large, the materials at each position in the tank body 11 are uniformly dispersed. Therefore, the problem of radial stratification of the material can be further improved, and the dispersion and stirring effects of the material can be further enhanced.

[0102] Also, the casing 61 outside the tank body 11 adjusts the temperature of the material in the tank body 11 by a temperature regulator 61 such as injected coolant or heating liquid, and further keeps the material at an appropriate temperature all the time, and the mixing effect of the material can be improved.

[0103] Furthermore, the flow blocking plate 21 is provided perpendicular to the side wall 111 of the tank body 11. After the material in the tank body 11 flows to the side wall 111 of the tank body 11 and then flows circumferentially along the side wall of the tank body 11 to form a horizontal circulation flow, by providing the flow blocking plate 21 perpendicular to the side wall 111 of the tank body 11, the cross-sectional area of the flow blocking plate 21 for the material can be increased, thereby enhancing the dispersion effect of the material.

[0104] Furthermore, by fixedly connecting the flow blocking plate 21 and the side wall 111 of the tank body 11, the stability between the flow blocking plate 21 and the tank body 11 can be improved, thereby improving the quality of the stirring equipment. The mounting structure of the flow blocking plate 21 can be simplified, and thereby the structure of the stirring equipment can also be simplified.

[0105] Furthermore, the stirring equipment of this embodiment includes a plurality of flow blocking plates 21, and the plurality of flow blocking plates 21 are provided symmetrically with respect to the first stirring shaft 121. Since the first stirring shaft 121 moves the material in the tank body 11 along the radial direction of the tank body 11 as the central stirring shaft of the stirring equipment to form a horizontal circulation flow, by providing a plurality of flow blocking plates 21 provided along the axial direction of the tank body 11 and symmetric with respect to the first stirring shaft 121 on the side wall 111 of the tank body 11, the dispersion and stirring effects of the material at each position in the tank body 11 can be improved.

[0106] Furthermore, the flow blocking plate 21 may be provided with through holes, thereby preventing the material from accumulating between the flow blocking plate 21 and the tank body 11, and the blocked material can flow out from the through holes.

[0107] Furthermore, the axial flow type stirring paddle is connected to one end of the second stirring shaft 131 located in the tank body 11, and the axial direction is set parallel to the axial direction of the second stirring shaft 131, and includes a propeller 132 configured to move the material in the tank body 11 and flow along the axial direction of the tank body 11.

[0108] The propeller 132 is provided coaxially with the second stirring shaft 132. The propeller 132 is driven by the second stirring shaft 131 to rotate. When the propeller 132 rotates, it can generate an upward or downward propulsive force on the material. Thereby, the material in the tank body 11 flows up and down.

[0109] Furthermore, the second stirring mechanism 13 is provided outside the tank body 11 and is connected to the other end of the second stirring shaft 131 to drive and rotate the second stirring shaft 131, thereby further including a second driving member 133 that moves and rotates the propeller 132. The second driving member 133 can realize the automatic stirring of the second stirring mechanism 13.

[0110] Furthermore, the second stirring mechanism 13 of this embodiment includes a plurality of propellers 132. The plurality of propellers 132 are provided on the second stirring shaft 131 at intervals along the axial direction of the second stirring shaft 131.

[0111] Since all of the plurality of propellers 132 of this embodiment are provided coaxially with the second stirring shaft 131, the axial propulsive force of the second stirring mechanism 13 on the material can be increased. Also, since the plurality of propellers 132 are provided at intervals, the resistance of the propellers 132 to the material can be reduced.

[0112] Furthermore, the radial flow type stirring paddle includes an anchor type stirring paddle 122 that is connected to one end of the first stirring shaft 121 located in the tank body 11, and the axial direction is set parallel to the axial direction of the first stirring shaft 121, and is configured to move the material in the tank body 11 and flow along the radial direction of the tank body 11.

[0113] The anchor type stirring paddle 122 is provided coaxially with the first stirring shaft 121. The anchor type stirring paddle 122 is driven by the first stirring shaft 121 to rotate. When the anchor type stirring paddle 122 rotates, it can generate a radial propulsive force on the material. Thereby, the material in the tank body 11 flows in the radial direction.

[0114] The anchor-type stirring paddle 122 has advantages such as a wide range of applicable viscosities and low power consumption, so it is possible to expand the application range of the stirring equipment and save power consumption.

[0115] Furthermore, the first stirring mechanism 12 is provided outside the tank body 11, and is connected to the other end of the first stirring shaft 121 to drive and rotate the first stirring shaft 121, and thereby further includes a first driving member 123 that moves and rotates the anchor-type stirring paddle 122. The first driving member 123 can realize the automatic stirring of the first stirring mechanism 12.

[0116] Furthermore, the first stirring mechanism 12 is provided on the bottom wall 112 of the tank body 11, and further includes a support member 124 configured to support one end of the first stirring shaft 121 connected to the anchor-type stirring paddle 122. The support member 124 can limit the position of the first stirring shaft 121, and the first stirring shaft 121 can rotate smoothly with respect to the tank body 11.

[0117] Furthermore, the anchor-type stirring paddle 122 is provided near the bottom wall 112 of the tank body 11, and is located between the propeller 132 and the bottom wall 112 of the tank body 11 along the axial direction of the tank body 11.

[0118] Since the anchor-type stirring paddle 122 is provided near the bottom wall 112 of the tank body 11, the anchor-type stirring paddle 122 can move the material and flow it along the side wall 111 of the tank body 11 in the radial direction of the tank body 11 and then flow upward along the side wall 111. Thereby, the lifted material is moved by the propeller 132 and continues to flow upward. Since the anchor-type stirring paddle 122 is provided far from the upper part of the tank body 11, the centrifugal force of the material at the upper part of the tank body 11 is small, and the material may be pushed out to the other side of the first stirring shaft 121, that is, the side where the propeller 132 is not installed. The material does not receive the action of the propeller 132 on this side, or the received action is small, and flows downward on the other side, thereby forming a circulating flow that moves up and down and left and right.

[0119] Furthermore, since the radius of the anchor-type stirring paddle 122 is close to the inner diameter of the tank body 11, the end of the anchor-type stirring paddle 122 is close to the side wall 111 of the tank body 11, the stirring area of the anchor-type stirring paddle 122 can be increased, the problem of material adhering to the side wall 111 can be improved, and the stirring effect of the material can be enhanced. The projection of the propeller 132 on the bottom wall 112 is located within the projection of the anchor-type stirring paddle 122 on the bottom wall 112. On the one hand, it is convenient to provide the flow blocking plate 21 on the side wall 111, and on the other hand, the material can be rapidly lifted from the bottom wall 112.

[0120] Furthermore, the stirring device covers the upper part of the tank body 11, specifically covers the opening of the accommodation cavity, and includes an upper head 14 for sealing the opening.

[0121] Optionally, the driving member of this embodiment can include a motor or the like. The motor is located outside the upper part of the tank body 11. Specifically, it is provided on the side opposite to the tank body 11 of the upper head 14 so as to facilitate the connection with the stirring shaft provided in the axial direction, thereby improving the driving efficiency of the motor.

[0122] Optionally, the first driving member includes a first variable frequency motor, for example, a variable frequency motor having parameters such as 0 - 60 RPM / MIN, and the second driving member includes a second variable frequency motor, for example, a variable frequency motor having parameters of 0 - 800 RPM / MIN. In order to improve the stirring effect of the material, the rotation speed of the variable frequency motor can be changed according to the specific needs of each stirring stage in the stirring process.

[0123] In some application scenarios, the rotation speed of the second variable frequency motor is controlled at 0 - 800 RPM / MIN, thereby preventing the cutting and demulsification of the material by the propeller 132.

[0124] Furthermore, the first end connected to the motor of the stirring shaft extends from the opening to the outside of the tank body 11, and a mechanical seal ring can be provided at the connection position between the stirring shaft and the upper sealing head 14, which can also improve the problem of liquid leakage from the connection position.

[0125] Furthermore, the upper head 14 can also be connected to the tank body 11 via a flange.

[0126] Furthermore, the stirring device is provided outside the bottom wall of the tank body 11, and further includes support legs 15 for attaching the tank body 11 to a square platform to improve stability.

[0127] In the embodiment of the present application, the anchor-type stirring paddle in the central part moves the material and makes it flow radially, and the propeller on the side obstructs the up-and-down flow of the material. Since the up-and-down and left-and-right circulation flows of the flowing material continuously hit the flow blocking plate in the tank body, the slurry at each position is uniformly dispersed. Due to the combined action of the anchor-type stirring paddle, the propeller, and the flow blocking plate, the serious layering phenomenon of the material caused by centrifugal force can be improved.

[0128] The above is only an embodiment of the present application, and does not limit the patent scope of the present application thereby. Any equivalent structure or equivalent process transformation carried out using the content of the specification and the attached drawings of the present application, or those directly or indirectly applied to other related technical fields, are all similarly included in the patent protection scope of the present application.
