Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, specifically a three-axis high-speed powder homogenizer. Background Technology

[0002] Homogenizers are mainly used for tissue dispersion in the biotechnology field, sample preparation in the pharmaceutical field, enzyme treatment in the food industry, detection of pesticide and veterinary drug residues in food, and in the pharmaceutical, cosmetic, paint, and petrochemical industries. The homogenizer adopts a stainless steel system, which can effectively separate the microorganisms on the surface of the sample and the contained microorganisms to homogenize the sample. The sample is placed in a disposable sterile homogenization bag and does not come into contact with the instrument, meeting the requirements of speed, accuracy, and good repeatability.

[0003] In the existing technology, most homogenizers use single-shaft mixing, which has low mixing efficiency and poor mixing effect. Furthermore, the powder tends to stick to the inner wall of the homogenizer during the mixing process, which affects the mixing quality and increases production costs. Therefore, a three-shaft high-speed powder homogenizer is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a three-sided shaft high-speed mixing and homogenizing machine, including a homogenizing machine body, wherein a rapid stirring mechanism is provided inside the homogenizing machine body;

[0006] The rapid stirring mechanism includes a top cover, which is fixed to the top of a positioning ring by bolts. A drive motor is fixedly connected to the middle of the top wall of the top cover. A connecting pipe is fixedly connected to the output shaft of the drive motor. A keyway is provided on the inner side of the connecting pipe. A key block is slidably connected to the inner side of the keyway. The key block is fixedly connected to the top of the outer side of the rotating shaft. A drive gear is passed through and fixedly connected to the upper part of the outer circumference of the rotating shaft. Multiple sets of annularly distributed driven gears are meshed on the outer side of the drive gear. A connecting shaft is fixedly connected to the bottom of each driven gear. Multiple sets of evenly distributed stirring discs are passed through and fixedly connected to the outer circumference of the connecting shaft. Multiple sets of annularly distributed stirring teeth are fixedly connected to the lower part of the outer circumference of the rotating shaft.

[0007] As a preferred technical solution of this utility model, the positioning ring is fixedly connected to the top of the inner side of the mounting frame, and a processing barrel is provided in the middle of the top wall of the homogenizer body.

[0008] As a preferred embodiment of this utility model, the processing barrel and the mounting frame are fitted with a clearance, and the mounting frame is located on the top inner side of the processing barrel.

[0009] As a preferred embodiment of this utility model, a connecting rod is fixedly connected to the bottom end of the rotating shaft, and a fixing rod is fixedly connected to the top left and right sides of the connecting rod.

[0010] As a preferred embodiment of this utility model, scraper plates are fixedly connected to both the front and rear sides of the two sets of fixing rods, and the scraper plates are all arc-shaped.

[0011] As a preferred embodiment of this utility model, universal wheels are provided at the four corners of the bottom wall of the homogenizer body, and a control panel is provided in the upper middle part of the front wall of the homogenizer body.

[0012] As a preferred embodiment of this utility model, all the connecting shafts pass through and are rotatably connected to the bottom of the mounting frame, and the rotating shaft is located in the middle between the three sets of connecting shafts.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of three-shaft high-speed mixing and homogenizing machine works by pouring powder into the processing barrel when mixing is required, then starting the drive motor. The output shaft of the drive motor rotates, causing the connecting pipe to rotate, which in turn rotates the shaft. During the rotation of the shaft, the drive gear drives the driven gear to rotate, which in turn causes the outer connecting shaft to rotate synchronously. During the rotation of the shaft, the outer stirring teeth and the outer stirring disc of the connecting shaft rotate to mix the powder inside the processing barrel in multiple directions, thereby improving the mixing efficiency and mixing quality.

[0015] 2. This type of three-sided shaft high-speed mixing homogenizer uses connecting rods and fixing rods at the bottom of the rotating shaft during powder processing. The connecting rods and fixing rods rotate synchronously during the rotation of the shaft and scrape the inner wall of the processing barrel with the help of scraper plates. This prevents the powder from sticking to the inner wall of the processing barrel and causing the powder to fail to mix properly, thus improving the practicality of the homogenizer.

[0024] The rapid stirring mechanism 2 includes a top cover 4, which is bolted to the top of the positioning ring 9. The top cover 4 seals the top of the mounting frame 8, thus protecting the internal components. A drive motor 5 is fixedly connected to the middle of the top wall of the top cover 4. A connecting pipe 10 is fixedly connected to the output shaft of the drive motor 5. The output end of the drive motor 5 is connected and fixed to the rotating shaft 13 through the cooperation of the connecting pipe 10, keyway 11, and key block 12. A keyway 11 is provided on the inner side of the connecting pipe 10. A key block 12 is slidably connected to the inner side of the keyway 11. The key block 12 is fixedly connected to the top outer side of the rotating shaft 13. The upper middle part of the outer circumference of the rotating shaft 13 is penetrated. A drive gear 14 is fixedly connected to the drive motor 5. During operation, the output shaft of the drive motor 5 rotates, causing the drive gear 14 to rotate. During the rotation of the drive gear 14, the outer driven gear 15 rotates. Multiple sets of annularly distributed driven gears 15 are meshed on the outer side of the drive gear 14. A connecting shaft 16 is fixedly connected to the bottom of each driven gear 15. Multiple sets of evenly distributed stirring discs 18 are fixedly connected through and to the outer periphery of the connecting shaft 16. Multiple sets of annularly distributed stirring teeth 17 are fixedly connected to the lower side of the outer periphery of the rotating shaft 13. During the rotation of the rotating shaft 13, the stirring teeth 17 and the stirring discs 18 on the outer side of the connecting shaft 16 rotate synchronously.

[0025] The positioning ring 9 is fixedly connected to the top of the inner side of the mounting frame 8. The processing barrel 3 is provided in the middle of the top wall of the homogenizer body 1.
