Description

Technical Field

[0001] This utility model relates to the field of three-dimensional motion mixer technology, specifically to a three-dimensional motion mixing tank with adjustable mixing intensity. Background Technology

[0002] The three-dimensional motion mixer is an industrial device used for highly uniform mixing of powdery and granular materials, primarily applied in pharmaceuticals, chemicals, food, light industry, and defense industries. The equipment consists of a base, transmission system, multi-directional motion mechanism, and mixing drum. Its working principle utilizes the three-dimensional composite motion (translation / rotation / tumbling) of the mixing drum to promote axial, radial, and circumferential three-dimensional flow and diffusion of materials, avoiding gravity segregation caused by centrifugal force. The equipment boasts a maximum loading rate of 90%, a mixing uniformity ≥99.9%, and mixing efficiency approximately 50% higher than ordinary models. The mixing drum features a rounded transition design to eliminate dead angles and supports variable frequency speed regulation and intelligent control systems, adapting to the mixing needs of materials with different specific gravities.

[0003] When mixing materials, overloading the mixer will cause it to work under overload, affecting the movement and mixing of materials; underloading the mixer will not fully utilize its efficiency, wasting energy and hindering material movement. Generally, the loading coefficient of a three-dimensional mixer can reach more than 0.9. However, due to the large differences in the density of raw materials, using a fixed-size mixing tank often results in insufficient mixing or low mixing efficiency when mixing heavy raw materials. Therefore, we propose a three-dimensional motion mixing tank with adjustable mixing intensity. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when mixing materials, excessive loading will cause the mixer to work under overload, affecting the movement and mixing of materials; while insufficient loading will not fully utilize the efficiency of the mixer, wasting energy and hindering the movement of materials. Generally, the loading coefficient of a three-dimensional mixer can reach more than 0.9. However, due to the large difference in density of raw materials, the use of a fixed-size mixing tank often results in insufficient mixing or low mixing efficiency when mixing heavy raw materials. This invention provides a three-dimensional motion mixing tank with adjustable mixing intensity.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A three-dimensional motion mixing tank with adjustable mixing intensity includes a drive base. Drive shafts are respectively provided at both ends of the front side of the drive base, and the drive shafts are drively connected to the power output shaft of the drive base. U-shaped rocker arms are hinged to the front sides of both drive shafts, and mixing tank fixing cylinders are staggered and pin-connected to the front sides of the two U-shaped rocker arms. The mixing tank fixing cylinder is a circular cylindrical structure with open ends, and multiple locking ring grooves are evenly spaced on the inner wall of the mixing tank fixing cylinder. An independent mixing tank is inserted into the center of the mixing tank fixing cylinder, and limit end caps are fixedly connected to both ends of the independent mixing tank. Locking mechanisms are fixedly connected to the side walls of the limit end caps corresponding to the locking ring grooves.

[0007] Furthermore, the side wall of the limiting end cover is provided with multiple locking block slots at equal intervals. A fan-shaped locking block is movably inserted into the outer side of each locking block slot, and a locking push rod is fixedly connected to the inner center of the fan-shaped locking block. A regular hexagonal groove is provided in the center of the outer side of the limiting end cover, and the inner end of the locking push rod penetrates the inner side wall of the locking block slot and is inserted into the regular hexagonal groove. A mating joint is fixedly connected to the end of the locking push rod corresponding to the side of the regular hexagonal groove, and a central push block is threadedly connected to the center of the regular hexagonal groove.

[0008] Furthermore, a reset spring is fixedly connected between the inner walls of the fan-shaped card block and the inner walls of the card block slot.

[0009] Furthermore, the central push block is a frustum-shaped structure with the large end facing outwards, and the inner side of the connector is provided with an inclined surface that matches the side surface of the central push block.

[0010] Furthermore, a crank handle connection screw hole is provided at the eccentric position on the outer side of the central push block.

[0011] Furthermore, the independent mixing tank is a capsule-shaped metal tank with hemispherical ends at both ends, and a tank opening is provided at the center of both ends of the independent mixing tank. The limiting end cover is provided with a sealing cover plate matching the tank opening on the side facing the independent mixing tank, and the sealing cover plate is fixedly connected to the tank opening of the independent mixing tank through a flange.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This invention utilizes independent mixing tanks of varying lengths for materials of different weights, and adjusts the mating position of the limiting end cap and locking ring groove to further fine-tune the stability and mixing intensity during the mixing process. This design not only improves mixing efficiency but also significantly enhances the flexibility and applicability of the equipment. Furthermore, the easy-to-disassemble design of the independent mixing tanks makes cleaning and maintenance more convenient and quick, effectively extending the service life of the equipment. In summary, this invention achieves adjustable mixing intensity through an innovative three-dimensional motion mixing method, providing a more efficient and flexible solution for material mixing.

[0014] 2. This utility model, through the design of a central push block, enables the synchronous pushing of multiple locking push rods, thereby controlling the engagement or disengagement of the sector-shaped locking block with the locking ring groove. In use, rotating the central push block causes its larger end to gradually approach the connector, pushing the connector and locking push rod outwards. The locking push rod causes the sector-shaped locking block to expand outwards and engage with the corresponding locking ring groove, thus securing the independent mixing tank. When disassembling the independent mixing tank, rotating the central push block in the opposite direction causes its larger end to gradually move away from the connector. At this point, under the action of the return spring, the sector-shaped locking block moves towards the center and disengages from the locking ring groove, allowing the independent mixing tank to be easily removed. This locking mechanism design is not only easy to operate but also provides a secure lock, greatly improving the stability and safety of the equipment.

[0015] 3. This utility model features an independent mixing tank with a capsule-shaped metal can structure, which is not only robust and durable but also possesses excellent sealing performance, effectively preventing material leakage during mixing. Simultaneously, the hemispherical ends enhance the stability of the independent mixing tank during three-dimensional movement, preventing violent shaking caused by material mixing and further improving the stability and mixing efficiency of the equipment. Furthermore, the sealing cover plate is fixedly connected to the tank opening via flanges, facilitating easy installation and disassembly while ensuring reliable sealing and guaranteeing smooth mixing. This design not only improves the practicality of the equipment but also significantly enhances its reliability and durability, providing users with a superior and more efficient mixing solution.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Please see Figures 1-4 This utility model provides a three-dimensional motion mixing tank with adjustable mixing intensity, including a drive base 1. The front ends of the drive base 1 are respectively provided with drive shafts 2, and the drive shafts 2 are connected to the power output shaft of the drive base 1. The front sides of the two drive shafts 2 are hinged to U-shaped rocker arms 3, and the front sides of the two U-shaped rocker arms 3 are staggered and pin-connected to the mixing tank fixing cylinder 4. The mixing tank fixing cylinder 4 is a circular cylindrical structure with open ends, and the inner wall of the mixing tank fixing cylinder 4 is provided with multiple locking ring grooves 14 at equal intervals. An independent mixing tank 5 is inserted into the center of the mixing tank fixing cylinder 4, and the two ends of the independent mixing tank 5 are respectively fixedly connected to limit end caps 6. The side walls of the limit end caps 6 are fixedly connected to the locking ring grooves 14 with locking mechanisms.

[0023] The working principle and usage process of this utility model are as follows: During use, the independent mixing tank 5 is placed inside the mixing tank fixing cylinder 4, and the independent mixing tank 5 is limited by the limiting end cap 6. At this time, the locking mechanism will engage with the corresponding locking ring groove 14 to fix the independent mixing tank 5 and prevent it from shaking during the mixing process. Subsequently, the drive base 1 is started. The power output shaft of the drive base 1 drives the drive shaft 2 to rotate, which in turn drives the U-shaped rocker arm 3 to swing. Since the mixing tank fixing cylinder 4 is staggered and pinned to the front of the two U-shaped rocker arms 3, the mixing tank fixing cylinder 4 will perform three-dimensional movement with the swing of the U-shaped rocker arm 3, thereby driving the independent mixing tank 5 to perform three-dimensional mixing. During this process, the mixing intensity of the independent mixing tank 5 can be adjusted by changing the speed and movement mode of the drive base 1 to meet the mixing requirements of different materials.

[0024] For materials of different weights, independent mixing tanks 5 of varying lengths are selected, and the mating position of the limiting end cap 6 and the locking ring groove 14 is adjusted to further fine-tune the stability and mixing intensity during the mixing process. This design not only improves mixing efficiency but also greatly enhances the flexibility and applicability of the equipment. Furthermore, the easy-to-disassemble design of the independent mixing tank 5 makes cleaning and maintenance more convenient and quick, effectively extending the service life of the equipment. In summary, this invention achieves adjustable mixing intensity through an innovative three-dimensional motion mixing method, providing a more efficient and flexible solution for material mixing.

[0025] In this embodiment, preferably, the sidewall of the limiting end cover 6 is provided with multiple locking slots 13 at equal intervals. A fan-shaped locking block 8 is movably inserted into the outer side of each locking slot 13, and a locking push rod 7 is fixedly connected to the inner center of the fan-shaped locking block 8. A regular hexagonal groove 15 is provided at the center of the outer side of the limiting end cover 6, and the inner end of the locking push rod 7 penetrates the inner sidewall of the locking slot 13 and is inserted into the regular hexagonal groove 15. A connector 9 is fixedly connected to the end of the locking push rod 7 corresponding to the side of the regular hexagonal groove 15, and a central push block 11 is threadedly connected to the center of the regular hexagonal groove 15. Through the central push block 11, the multiple locking push rods 7 can be pushed synchronously, thereby controlling the engagement or disengagement of the fan-shaped locking block 8 and the locking ring groove 14. In use, rotating the central push block 11 causes its larger end to gradually approach the connector 9, pushing the connector 9 and locking push rod 7 outward. The locking push rod 7 then causes the fan-shaped locking block 8 to expand outward and engage with the corresponding locking ring groove 14, thus securing the independent mixing tank 5. When it is necessary to disassemble the independent mixing tank 5, rotating the central push block 11 in the opposite direction causes its larger end to gradually move away from the connector 9. At this time, under the action of the return spring 10, the fan-shaped locking block 8 moves towards the center and disengages from the locking ring groove 14, allowing the independent mixing tank 5 to be easily removed. This locking mechanism design is not only easy to operate but also provides a secure lock, greatly improving the stability and safety of the equipment.

[0026] In this embodiment, preferably, a reset spring 10 is fixedly connected between both sides of the inner wall of the sector-shaped locking block 8 and both sides of the inner side wall of the locking block slot 13; through the reset spring 10, after the central push block 11 releases the push on the locking push rod 7, the sector-shaped locking block 8 is automatically pulled back to its original position, facilitating the next locking operation. This design not only improves the automation level of the equipment, but also extends the service life of the locking mechanism.

[0027] In this embodiment, preferably, the central push block 11 is a frustum-shaped structure with its larger end facing outwards, and the inner side of the connector 9 is provided with an inclined surface that matches the side surface of the central push block 11. Through the frustum-shaped structure of the central push block 11 with its larger end facing outwards, and the inclined surface on the inner side of the connector 9 that matches the side surface of the central push block 11, the larger end of the central push block 11 can gradually move closer to or further away from the connector 9 when the central push block 11 is rotated, thereby achieving the pushing or releasing of the locking push rod 7. This structural design not only achieves synchronous operation of the locking mechanism but also greatly improves the ease of operation and stability of the equipment.

[0028] In this embodiment, preferably, a crank handle connecting screw hole 12 is provided at an eccentric position on the outer side of the central push block 11. The crank handle can be easily connected through the crank handle connecting screw hole 12, thereby enabling the rotation of the central push block 11. This design not only makes operation more labor-saving but also improves the operational flexibility of the equipment. During use, simply insert the crank handle into the crank handle connecting screw hole 12 and rotate the crank handle to easily control the rotation of the central push block 11, thereby achieving the fixing or disassembly of the independent mixing tank 5. This user-friendly design greatly reduces the difficulty of operation and improves work efficiency.

[0029] In this embodiment, preferably, the independent mixing tank 5 is a capsule-shaped metal tank with hemispherical ends at both ends, and each end of the independent mixing tank 5 has a tank opening at its center. The limiting end cover 6 has a sealing cover plate matching the tank opening on the side facing the independent mixing tank 5, and the sealing cover plate is fixedly connected to the tank opening of the independent mixing tank 5 through a flange. The independent mixing tank 5 with its capsule-shaped metal tank structure is not only structurally robust and durable, but also has excellent sealing performance, effectively preventing material leakage during the mixing process. Simultaneously, the hemispherical ends at both ends make the independent mixing tank 5 more stable during three-dimensional movement, avoiding violent shaking caused by material mixing, further improving the stability and mixing efficiency of the equipment. Furthermore, the design of the sealing cover plate being fixedly connected to the tank opening of the independent mixing tank 5 through a flange not only facilitates installation and disassembly, but also ensures reliable sealing, effectively guaranteeing the smooth progress of the mixing process. This design not only improves the practicality of the equipment, but also greatly enhances its reliability and durability, providing users with a higher quality and more efficient mixing solution.
