Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical powder production equipment, in particular to a raw material mixing equipment based on pharmaceutical powder production. Background Art

[0002] In the process of preparing powders or pulverized powders, pharmaceutical companies usually need to mix two or more drugs to meet production requirements.

[0003] For example, the Chinese patent with publication number CN206325501 U discloses a powder drug raw material grading and mixing equipment that is easy to clean, including a tank body; the interior of the tank body is divided into a pre-mixing chamber and a mixing chamber by a partition, and an upper cover is provided at the top opening; a driving device, a transmission device, a drug feed pipe and a cleaning device are provided on the upper cover; the driving device is composed of a first motor, a first reducer and a transmission shaft; the transmission device is composed of a first transmission wheel, a second transmission wheel and a transmission belt; the top of the first transmission wheel is fixedly connected to the transmission shaft, and the bottom is fixedly connected to the first stirring device; the second transmission wheel is connected to the first transmission wheel through a transmission belt, and the bottom surface of the second transmission wheel is fixedly connected to the second stirring device; a spiral agitator is provided in the mixing chamber; the utility model pre-mixes the drug raw materials added to the drug feed pipe by the first stirring device and the second stirring device; and the drug raw materials are circulated and stirred and mixed by the spiral agitator.

[0004] This patent has some shortcomings when used, such as: the device in this patent cleans the inner cavity of the tank through a cleaning device, but after cleaning, a large amount of liquid water droplets will still remain on the inner wall of the tank. If the tank is not dried, the medical powder will clump after contacting the water droplets, causing the through holes on the partition to be blocked, and the overall mixing of the powder is uneven, and the time required by the natural drying method is too long to meet the needs of medical powder production; in addition, the lower part of the device is only stirred by a single spiral stirrer. When mixing multiple medical powders, the overall mixing effect is relatively general, and the mixing efficiency is extremely low, which cannot meet the needs of mixing large quantities of medical powders. In view of this, we propose a raw material mixing device based on medical powder production. Utility Model Content

[0049] In this embodiment, the stirring mechanism includes:

[0050] A gear ring 6, which is fixedly mounted on the lower surface of the upper cover 2, a driving wheel 7 rotatably connected to the lower surface of the upper cover 2 is arranged at the axial position of the gear ring 6, a plurality of driven wheels 8 equidistantly distributed on the circumference of the driving wheel 7 are meshed and connected, and the plurality of driven wheels 8 are all meshed with the gear ring 6, an annular groove 9 with a T-shaped cross section is provided on the lower surface of the upper cover 2, a limit block 10 movably connected to the annular groove 9 is rotatably mounted on the upper surface of the driven wheel 8, a motor 11 is mounted on the upper surface of the upper cover 2, and the output shaft of the motor 11 passes through the upper surface of the upper cover 2 and extends to the bottom to be coaxially connected to the driving wheel 7, a spiral stirring roller 12 is coaxially connected to the bottom of the driving wheel 7, a secondary stirring roller 13 is coaxially connected to the bottom of the driven wheel 8, and a plurality of evenly distributed stirring blades are arranged on the secondary stirring roller 13;

[0051] In this embodiment, the heat dissipation component includes:

[0052] The outer shell 18 is fixedly installed in the heat dissipation port 17. The outer shell 18 is fixed with a horizontal plate 19. A motor 20 is installed on the horizontal plate 19. The output shaft of the motor 20 is coaxially connected with a fan blade 21. A mesh plate 22 is fixed at the inner opening of the outer shell 18. A dustproof net 23 is installed at the outer opening of the outer shell 18.

[0053] Among them, the working principle of this device is as follows:

[0054] When feeding, the two electric push rods 5 are started, and the telescopic rods of the two electric push rods 5 move upward, and push the upper cover 2 to move upward, so that the opening of the inner tank body 3 leaks out, and then the operator pours different powder raw materials into the inner cavity of the inner tank body 3. After the feeding is completed, the two electric push rods 5 are started again, and the telescopic rods of the two electric push rods 5 move downward and drive the upper cover 2 downward until the upper cover 2 is closed with the outer tank body 1 and the inner tank body 3; it is worth adding that the cross-section of the inner tank body 3 is a T-shaped structure, and the upper surface of the inner tank body 3 is flush with the upper surface of the outer tank body 1. For details, please refer to the drawings in the specification. Figure 2 - Figure 5 ;

[0055] During stirring, the motor 11 is started, the output shaft of the motor 11 rotates and drives the driving wheel 7 to rotate, the driving wheel 7 drives the driven wheel 8 to rotate, and under the action of the ring gear 6, the multiple driven wheels 8 perform planetary gear motion around the driving wheel 7 and rotate along the annular groove 9. When the driving wheel 7 rotates, it drives the spiral stirring roller 12 to rotate, and when the driven wheel 8 rotates, it drives the auxiliary stirring roller 13 to rotate. In the above process, the multiple auxiliary stirring rollers 13 can quickly mix and stir the powder materials on the side of the spiral stirring roller 12, and when the spiral stirring roller 12 rotates, the powder materials at the bottom center of the inner cavity of the inner tank body 3 are rolled upward. Through the cooperation of the spiral stirring roller 12 and the multiple auxiliary stirring rollers 13, the multiple powder materials in the inner cavity of the outer tank body 1 can be quickly and evenly mixed, which solves the problems of poor mixing effect and low mixing efficiency in traditional mixing devices.

[0056] After the mixing is completed, open the control valve on the discharge pipe to discharge the mixed raw materials from the inner cavity of the inner tank body 3;

[0057] During cleaning, the two electric push rods 5 are started to open the upper cover 2. The operator can flush the inside with a high-pressure water pipe or wipe the inside of the device with a clean and soft cloth. After cleaning, the cleaning water is discharged from the discharge pipe at the bottom. Then, the multiple sets of electric heating tubes 14 are started. The multiple sets of electric heating tubes 14 work and generate heat to heat the inner tank body 3 and accelerate the drying of the remaining water droplets on the inner wall of the inner tank body 3.

[0058] When drying is completed, the heat dissipation component is started and the multiple groups of electric heating tubes 14 are stopped. At this time, part of the heat in the inner cavity of the inner tank body 3 escapes from the top opening of the inner tank body 3 and part is dispersed into the interlayer under the action of the multiple groups of heat dissipation fins 16. When the heat dissipation component is working, the motor 20 works, and the output shaft of the motor 20 drives the fan blades 21 to rotate and form wind. It is worth adding that the wind directions of the two heat dissipation components in the device of the present application are opposite, that is, one of the heat dissipation components is the air inlet side, and the other heat dissipation component is the air outlet side. Through the action of the two heat dissipation components, the heat in the interlayer can be quickly discharged to the outside. After cooling down, the heat dissipation component is closed again;

[0059] After cleaning, drying and cooling, close the upper cover 2 and the control valve on the discharge pipe.

[0060] By setting a stirring mechanism, the motor 11 is used for driving, and the driving wheel 7 is used for transmission, so that the multiple driven wheels 8 can perform circular motion around the axis of the driving wheel 7 in the gear ring 6, and rotate at the same time, so that the multiple auxiliary stirring rollers 13 and the stirring blades on the auxiliary stirring rollers 13 can fully stir and mix the raw materials at various locations in the inner cavity of the inner tank body 3, and the spiral stirring roller 12 makes the powder raw materials at the bottom center of the inner cavity of the inner tank body 3 surge upward. Through the cooperation of the spiral stirring roller 12 and the multiple auxiliary stirring rollers 13, the various powder raw materials in the inner cavity of the outer tank body 1 can be quickly stirred. The inner tank body 3 is quickly and evenly mixed, which solves the problems of poor mixing effect and low mixing efficiency in traditional mixing devices; by setting up multiple groups of electric heating tubes 14, the electric heating tubes 14 are used to heat the inner tank body 3, so that the water droplets remaining in the inner tank body 3 can be quickly dried, avoiding the phenomenon that the powder raw materials agglomerate due to the presence of water droplets in the inner tank body 3, and then through the heat dissipation component and multiple groups of heat dissipation fins 16, the inner tank body 3 after heating and drying can be quickly cooled down, so that it can be put into the next mixing work more quickly. The device has an excellent mixing effect and a high mixing efficiency.
