Technical Field

[0001] This utility model relates to the field of powder production equipment technology, specifically a mixing device for powder production. Background Technology

[0002] Powders are preparations made by mixing, pulverizing, and then remixing one or more pharmaceutical agents, fillers, and small amounts of adjuvants to a certain fineness. They can be used directly or diluted with appropriate fillers and adjuvants before use.

[0003] Therefore, mixing equipment is usually required in the powder production process to quickly and evenly mix various raw material components together to improve production efficiency;

[0004] However, existing mixing equipment typically only provides basic mixing. When mixing powders that may have high adhesiveness, the powder tends to adhere to the inner wall of the mixing tank. This adhesion can lead to uneven mixing, resulting in unstable product composition and performance. Furthermore, the powder residue requires regular cleaning, increasing production time and costs. Severely adhered mixing tanks may even require shutdown for cleaning, reducing production efficiency. Therefore, this paper proposes a mixing device for powder production to address these issues.

Multiple cleaning components for cleaning the inner wall of the mixing tank are provided on both straight rods. The multiple cleaning components on the two straight rods are arranged alternately.

[0009] Furthermore, the cleaning assembly includes two support columns for connection. One end of each support column is fixedly connected to the straight rod, and the other end is fixedly connected to a support rod. The support rod is rotatably connected to a support frame, and the support frame is provided with a scraper for cleaning the inner wall of the mixing tank.

[0010] Furthermore, the support frame is provided with a plurality of support springs for support, and the other end of the support springs is fixedly connected to the straight rod.

[0011] Furthermore, the discharge assembly includes a connecting platform, which is fixedly connected to the bottom of the hopper. The connecting platform is provided with a discharge pipe for discharging material, and a valve is provided on the discharge pipe.

[0012] Furthermore, a stirring blade for assisting material feeding is fixedly connected to the bottom of the drive motor, and the stirring blade is located above the discharge pipe.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

The stirring rods 23 include straight rods and inclined rods. The straight rods and inclined rods are adapted to the mixing tank 16 and the hopper 17. Multiple cleaning components 4 for cleaning the inner wall of the mixing tank 16 are provided on both straight rods. The multiple cleaning components 4 on the two straight rods are arranged alternately.

[0027] As a preferred technical solution in this embodiment: In actual use, the operator can first open the cover plate 12 and put the powder to be mixed into the mixing chamber 15 provided inside the protective shell 1. Then, the operator can control the transmission motor 21 to drive the transmission shaft 22 to rotate. During the rotation of the transmission shaft 22, the stirring rod 23 can be driven to rotate. During the rotation of the stirring rod 23, the powder can be effectively mixed. At the same time, during the rotation of the stirring rod 23, the cleaning component 4 can be driven to clean the powder adhering to the inner wall of the mixing tank 16, so as to prevent the highly viscous powder from adhering to the inner wall of the mixing tank 16 during mixing.

[0028] The technical effects of the above embodiments are as follows: by setting the drive shaft 22 and the stirring rod 23, the powder can be effectively mixed during use; by setting the cleaning component 4, the powder can be effectively prevented from adhering to the mixing tank 16 during the mixing process, thereby avoiding the need for frequent cleaning by the staff and the impact of powder residue on the quality of subsequent powders, which would make the composition and performance of the product unstable.

[0029] Furthermore, in this embodiment, the bottom of the top plate 11 is also provided with a baffle 18. By providing the baffle 18, the flow path of the powder can be changed, ensuring that the powder can be more evenly distributed during the mixing process; the bottom of the protective shell 1 is also provided with a support leg 14 for support.

[0030] Example 2:

[0031] Please see Figure 1-7To further enhance the cleaning effect on the interior of the mixing tank 16, the cleaning component 4 in this embodiment includes two connecting support columns 41. One end of each support column 41 is fixedly connected to a straight rod, and the other end is fixedly connected to a support rod 42. The support rod 42 is rotatably connected to a support frame 43, and the support frame 43 is equipped with a scraper 44 for cleaning the inner wall of the mixing tank 16. The support frame 43 is equipped with multiple support springs 45 for support, and the other end of each support spring 45 is fixedly connected to the straight rod.

[0032] As a preferred technical solution in this embodiment: In actual use, when the operator controls the stirring rod 23 to drive the cleaning component 4 to rotate, the support spring 45 can effectively support the scraper 44, so that the scraper 44 can always keep in contact with the inner wall of the mixing tank 16, which can effectively clean the inner wall of the mixing tank 16; when the mixing is completed and the operator needs to discharge the material, the valve 33 can be opened to allow the mixed powder to be discharged through the discharge pipe 32. At the same time, when the drive motor 21 rotates, it can drive the stirring blade 24 to rotate. During the rotation of the stirring blade 24, the powder can be effectively prevented from accumulating at the discharge pipe 32, which can effectively increase the discharge efficiency.

[0033] The technical effects of the above embodiments are as follows: by providing a support spring 45 on the support frame 43 for support, it can be effectively ensured that the scraper 44 can always keep in contact with the inner wall of the mixing tank 16, thereby avoiding wear and tear on the scraper 44 after long-term use, thus preventing it from failing to achieve the cleaning effect; by providing a stirring blade 24 at the bottom of the drive motor 21, it can effectively achieve the effect of assisting material feeding, thus preventing the accumulation of medicine powder in the discharge pipe 32.

[0034] The working principle of the above embodiments is as follows:

[0035] 1. In actual use, the operator can first open the cover 12 and put the powder to be mixed into the mixing chamber 15 inside the protective shell 1. Then, the operator can control the drive motor 21 to drive the drive shaft 22 to rotate. During the rotation of the drive shaft 22, the stirring rod 23 will rotate, which will effectively mix the powder. At the same time, the rotation of the stirring rod 23 will drive the cleaning component 4 to clean the powder adhering to the inner wall of the mixing tank 16, preventing the sticky powder from adhering to the inner wall of the mixing tank 16 during mixing.

[0036] II. In actual use, when the operator controls the stirring rod 23 to drive the cleaning component 4 to rotate, the support spring 45 can effectively support the scraper 44, so that the scraper 44 can always keep in contact with the inner wall of the mixing tank 16, which can effectively clean the inner wall of the mixing tank 16. When the mixing is completed and the operator needs to discharge the material, the valve 33 can be opened to allow the mixed powder to be discharged through the discharge pipe 32. At the same time, when the drive motor 21 rotates, it can drive the stirring blade 24 to rotate. During the rotation of the stirring blade 24, the powder can be effectively prevented from accumulating at the discharge pipe 32, which can effectively increase the discharge efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
