[0017] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0018] like Figure 1 and Figure 2As shown, a solid powder pharmaceutical preparation apparatus includes a storage tank 1, a dissolving tank 2, and a storage pool 3. A feed pipe 4 is provided on one side of the storage tank 1, and the feed pipe 4 is connected to an external pharmaceutical container. A filter 5 is provided on the feed pipe 4 to prevent impurities from entering the storage tank 1.

[0019] A conveying device 6 is provided on the other side of the storage tank 1. The other end of the conveying device 6 is connected to the feed end of the dissolving tank 2. The discharge end of the dissolving tank 2 is connected to a discharge pipe 13, and the other end of the discharge pipe 13 is connected to the storage tank 3. A transfer pump 12 and a discharge valve 11 are provided on the discharge pipe 13. The transfer pump 12 is used to transport the medicine in the dissolving tank 2 to the storage tank 3.

[0020] The medicine storage tank 1 is equipped with a metering mechanism, which includes a vibrator 16, a heater 17, a gate 18, and a tilting valve 19. The vibrator 16 is a conventional vibrator that automatically activates during drug preparation to prevent solid powder from bridging and affecting the dosage concentration. The heater 17 dries the solid powder to prevent solidification; it can be heated by water pipes or electric heating wires. There is a gap between the gate 18 and the tilting valve 19. When the gate 18 is opened and the tilting valve 19 is closed, the medicine in the storage tank 1 falls between the gate 18 and the tilting valve 19. Afterwards, the gate 18 is closed and the tilting valve 19 is opened, ensuring accurate metering and precise dispensing of the solid medicine each time. The lower end of the tilting valve 19 is connected to the transmission device 6 for drug delivery.

[0021] The transmission device 6 includes a transmission pipe 61, a spiral auger blade 62, and an air supply device. The spiral auger blade 62 and the transmission pipe 61 are existing spiral transmission structures that can transport solid powder medicines to the dissolving tank 2.

[0022] This design also includes an added gas supply device, which consists of a gas generator 21 and a gas supply pipe 20. The gas generator 21 generates gas and delivers the gas to the feed end of the transmission pipe 61 through the gas supply pipe 20. This can prevent the solid powder medicine from slipping during the screw conveyor. By combining screw conveyor and gas pressurization, the solid powder medicine is delivered to the dissolving tank 2 to complete the preparation of the medicine.

[0023] The feed end of the dissolving tank 2 is equipped with a spray system, which includes a water supply pipe 7 and several water curtain nozzles 8. This design includes multiple water curtain nozzles 8, installed in two groups to form a water curtain for dust removal. The water curtain nozzles 8 are connected to an external water source via the water supply pipe 7. The dissolving tank 2 also has a water supply system 22, which is connected to municipal industrial water and equipped with metering devices. Water supply is controlled by a solenoid valve to allow water to flow in or out. The water supply system 22 is used to provide water for preparing the chemicals.

[0024] The spraying system controls water intake and shutdown via a solenoid valve. A booster pump 9 is installed at the water inlet to automatically adjust water pressure and prevent dust from solid powder from clogging the spray nozzles. Two exhaust pipes 10 are installed at the feed end of the dissolving tank 2 to completely remove air introduced during feeding.

[0025] The dissolving tank 2 is equipped with an empty pipe 14 for cleaning the tank during maintenance. The dissolving tank 2 is also equipped with a stirrer 15 for dissolving and stirring the medicine, accelerating the dissolution and completing the preparation.

[0026] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
