Description

Technical Field

[0001] The present application relates to the field of dispersion kettles, and in particular to a sealed stirring dispersion kettle. Background Art

[0002] At present, stirring and dispersing kettles are widely used for mixing and dispersing various liquid and solid materials. Stirring and dispersing kettles are usually driven by motors to rotate stirring paddles and dispersing disks. The stirring paddles make two or more miscible liquids in the kettle reach a uniform degree of molecular scale. The dispersing disk generates shear force through high-speed rotation, breaking the particles or agglomerates in the materials into smaller units, thereby achieving efficient dispersion of the materials. The dispersing disk and stirring paddles work together in the dispersing kettle, so that the materials can quickly reach a state of uniform mixing and efficient dispersion. The stirring paddles provide the necessary energy and flow state, while the dispersing disk further refines the material particles through shear force to improve the dispersion efficiency.

[0003] In the related art, the stirring and dispersing kettle increases the stirring area and shear force by adopting a multi-layer blade design, but since each blade can only cover the stirring area at a specific height, the stirring range is still limited, and the interlayer spacing between the multi-layer stirring paddles has a significant impact on the stirring effect. Too large an interlayer spacing may lead to insufficient stirring, while too small an interlayer spacing may cause interference and eddy currents. Therefore, the mixing efficiency of the materials cannot be achieved by simply increasing the number of blades in the kettle, so there is still room for improvement. Summary of the invention

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] The present application embodiment discloses a sealed stirring and dispersing kettle, referring to Figure 1 and Figure 2 , including a kettle body 1, in which a central axis 3 is rotatably connected, and the central axis 3 is located at the axial position of the kettle body 1. A plurality of axially distributed dispersion disks 2 are arranged on the outer peripheral surface of the central axis 3. A central cylinder 4 is rotatably connected to the top position of the kettle body 1, and the central cylinder 4 is rotatably sleeved on the central axis 3 through a sealed bearing. A U-shaped stirring paddle 6 is arranged in the kettle body 1, and two vertical sections 61 of the U-shaped stirring paddle 6 are fixed to the outer peripheral surface of the central cylinder 4 through a connecting rod, so that the U-shaped stirring paddle 6 is rotatably connected to the inside of the kettle body 1 through the central cylinder 4. Among them, the U-shaped stirring paddle 6 is close to the inner wall of the kettle body 1. Among them, the horizontal section of the U-shaped stirring paddle 6 is close to the inner bottom wall of the kettle body 1, and the two vertical sections 61 of the U-shaped stirring paddle 6 are close to both sides of the inner peripheral wall of the kettle body 1. In this embodiment, a first driving member 7 for driving the central axis 3 to rotate and a second driving member 8 for driving the U-shaped stirring paddle 6 to rotate are installed on the top of the kettle body 1. The first driving member 7 adopts a first motor, which is installed at the bracket on the top of the kettle body 1 and the output shaft is coaxially fixedly connected with the central axis 3. The second driving member 8 adopts a second motor and a synchronous belt mechanism, which is installed at the bracket and the output shaft is linked to the central cylinder 4 through the synchronous belt mechanism. The first driving member 7 and the second driving member 8 drive to realize independent control of the rotation function of the U-shaped stirring paddle 6 and the dispersion disk 2.

[0032] In this embodiment, the inner wall of the kettle body 1 is provided with a plurality of vertically distributed annular chutes 121, each of which is provided with a highest position 122 and a lowest position 123 on the inner wall of the kettle body 1, and the highest position 122 and the lowest position 123 of the annular chutes 121 are respectively disposed on both sides of the central axis 3, and each vertical section 61 of the U-shaped stirring paddle 6 is vertically slidably connected with a plurality of horizontal stirring rods 5, and the ends of the plurality of horizontal stirring rods 5 are respectively slidably connected in the plurality of annular chutes 121, and the end surfaces of the horizontal stirring rods 5 are covered with a wear-resistant layer. When the second driving member 8 drives the U-shaped stirring paddle 6 to rotate, the U-shaped stirring paddle 6 drives the horizontal stirring rod 5 to rotate, and the horizontal stirring rod 5 moves back and forth between the highest position 122 and the lowest position 123 under the guidance of the annular chutes 121 and the driving action of the U-shaped stirring paddle 6 to achieve the purpose of swinging up and down. Not only the stirring area is increased, but also the stirring efficiency is improved, avoiding the phenomenon of insufficient stirring or eddy current caused by the interlayer spacing problem of traditional multi-layer blades. At the same time, the reciprocating motion of the horizontal stirring rod 5 at different heights can better break up the agglomerates in the material and improve the dispersion effect. In addition, the cooperation between the end of the horizontal stirring rod 5 and the annular slide groove 121 ensures the stability and reliability of the stirring process, and further improves the mixing uniformity and dispersion quality of the material.

[0033] Reference Figure 3 and Figure 4 In this embodiment, the vertical section 61 of the U-shaped stirring paddle 6 is provided with a vertical groove 611, which extends in the length direction of the vertical section 61 of the U-shaped stirring paddle 6, and is a cross-shaped through groove that passes through the four sides of the vertical section 61. The horizontal stirring rod 5 passes through the vertical groove 611 horizontally, and the two sides of the horizontal stirring rod 5 are engaged and slid on the two sides of the vertical groove 611, so that the horizontal stirring rod 5 can not only slide freely in the vertical groove 611 while rotating with the U-shaped stirring paddle 6, but also improve the sliding stability of the horizontal stirring rod 5, and reduce the situation where the end of the horizontal stirring rod 5 slips out of the annular slide groove 121.

[0034] In this embodiment, a vertically arranged connecting rod (not shown in the figure) is fixed between the upper and lower adjacent horizontal stirring rods 5. The connecting rod can effectively enhance the overall structural stability between the several horizontal stirring rods 5 on the same side, and prevent the centrifugal force generated by high-speed rotation from causing the horizontal stirring rod 5 to deform or escape from the annular slide groove 121. At the same time, the connecting rod can also reduce the relative movement between the horizontal stirring rods 5 to a certain extent, avoid wear and vibration caused by frequent reciprocating swinging, thereby extending the service life of the equipment and improving the stirring efficiency.

[0035] Reference Figure 4 and Figure 5In this embodiment, in order to facilitate the cleaning of the internal structure of the kettle body 1, the kettle body 1 is designed as a detachable structure. Specifically, the kettle body 1 includes a bottom tank 11 with an opening at the upper end, an inner cylinder 12 arranged inside the bottom tank 11, and a top cover 13 for sealing the upper opening of the bottom tank 11, wherein the inner cylinder 12 is a cylinder structure with openings at both ends, the outer wall of the inner cylinder 12 is sealed and fitted to the inner circumferential wall of the bottom tank 11, a magnet is embedded at the bottom of the top cover 13, and the top of the inner cylinder 12 is magnetically fixed to the bottom of the top cover 13, so as to facilitate the overall disassembly and assembly of the kettle body 1 structure. The top of the bottom tank 11 and the bottom of the top cover 13 are detachably connected by a flange to improve the sealing effect of the kettle body 1. In addition, an annular chute 121 is opened at the inner circumferential wall of the inner cylinder 12. Therefore, the stubborn lumps in the annular chute 121 can be easily cleaned by taking out the inner cylinder 12 and then performing the cleaning step of the annular chute 121.

[0036] Reference Figure 4 and Figure 6 In this embodiment, the inner cylinder 12 includes two semi-circular plate units 124, which are spliced ​​together to form a cylinder with upper and lower openings. It is convenient to complete the installation and disassembly of the inner cylinder 12 and the horizontal stirring rod 5, and it is also convenient to clean and maintain the materials in the kettle body 1. Among them, the two semi-circular plate units 124 have the same structure, and the highest point 122 and the lowest point 123 of the annular chute 121 are respectively located on both sides of the semi-circular plate unit 124, so as to facilitate the batch processing and manufacturing of the semi-circular plate unit 124 and the assembly quality of the inner cylinder 12.

[0037] In this embodiment, connecting protrusions 125 are fixed on both sides of the outer circumferential wall of the inner cylinder 12, and the connecting protrusions 125 extend along the height direction of the inner cylinder 12. In addition, both sides of the inner circumferential wall of the bottom tank 11 are provided with card slots 111, which extend vertically and are opened at the upper end, so that the inner cylinder 12 can be easily inserted into the bottom tank 11 and fixed through the cooperation of the card slots 111 and the connecting protrusions 125, effectively preventing the inner cylinder 12 from loosening or shifting during use, and improving the overall stability and safety of the equipment. At the same time, this plug-in installation method also facilitates the disassembly and maintenance of the inner cylinder 12, simplifies the operation process, and improves work efficiency. It should be emphasized that the connecting protrusions 125 are arranged on the outside of both sides of each semi-circular plate unit 124. When the two semi-circular plate units 124 are spliced ​​into the inner tube 12, the connecting protrusions 125 at both ends of the two semi-circular plate units 124 are flattened into a complete body. When they are snap-fitted with the slots 111 of the bottom tank 11, the tightening effect between the two semi-circular plate units 124 is further improved, which is beneficial to improving the sealing of the inner tube 12.

[0038] The implementation principle of a sealed stirring and dispersing kettle in the embodiment of the present application is as follows: the central axis 3 is driven to rotate by the first driving member 7, which drives the dispersion disc 2 to rotate at high speed, generates a strong shear force, breaks the particles or agglomerates in the material into smaller units, and realizes efficient dispersion. The second driving member 8 drives the U-shaped stirring paddle 6 to rotate, and the U-shaped stirring paddle 6 drives the horizontal stirring rod 5 to swing up and down in the annular chute 121. The up and down swinging of the horizontal stirring rod 5 increases the stirring range, eliminates the stirring dead angle, and improves the mixing uniformity of the material. The coordinated work of the dispersion disc 2 and the horizontal stirring rod 5 forms a multi-level and all-round stirring effect, which significantly improves the mixing and dispersion efficiency of the material. The design of the inner cylinder 12 and the top cover 13 ensures the airtightness of the kettle body 1, prevents material leakage, and is easy to clean and maintain. The linkage design of the horizontal stirring rod 5 and the connecting rod makes the movements of each horizontal stirring rod 5 more coordinated, generates a greater stirring force and a more complex flow pattern, and further improves the stirring effect.

[0039] Through the above design, the sealed stirring and dispersing kettle of this embodiment can effectively improve the uniformity and efficiency of stirring and dispersing while maintaining a closed structure, especially when processing high-viscosity or easy-to-cake materials. The up and down swinging movement of the horizontal stirring rod 5 not only increases the stirring range, but also reduces the local stirring dead angle, so that the materials in the entire kettle body 1 can be fully mixed and dispersed. This design significantly improves production efficiency, reduces energy consumption, and also ensures the quality and consistency of the materials.

[0040] Reference Figure 7 The difference between Example 2 and Example 1 is that: several layers of stirring areas are divided inside the kettle body 1 in the vertical direction, and the horizontal plane where the dispersion disk 2 is located is used as the boundary between the upper and lower stirring areas, and several annular chutes 121 are respectively arranged at several layers of stirring areas, and the highest point 122 and the lowest point 123 of the annular chute 121 are both located in the stirring area, and the end of the horizontal stirring rod 5 away from the inner wall of the kettle body 1 extends toward the central axis 3 and is located between adjacent dispersion disks 2. On the basis of avoiding the collision between the horizontal stirring rod 5 and the dispersion disk 2, the shear force generated by the dispersion disk 2 can be fully utilized to further refine the material particles, improve the dispersion efficiency, improve the problem of insufficient stirring in the traditional stirring and dispersing kettle, and achieve efficient and uniform material mixing and dispersion.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
