Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical dissolvers, and in particular to a pharmaceutical dissolver for pharmaceutical analysis. Background Technology

[0002] A drug dissolver is a device specifically designed to quickly and uniformly dissolve solid drugs into a liquid form. It is commonly used in the medical, laboratory, or pharmaceutical fields. In drug analysis, it is often necessary to dissolve drugs using a drug dissolver. Chinese Patent Application No. CN202223391660.6 discloses a drug dissolving device that is easy to clean. When the stirring shaft rotates, the stirring frame will also rotate, thereby stirring the drug inside the drug dissolving tank so that the drug can dissolve faster. After the dissolved drug is taken out, the stirring frame is raised, and then the residue scrapers A, B and C are installed on both sides and the bottom of the stirring frame. The stirring shaft is rotated again, so that the residue scrapers A, B and C scrape off the drug residue inside the power housing and the bottom, or the drug residue adhering to it, so that workers can easily take it out and clean the drug residue. However, most existing drug dissolvers use a stirring rod to stir the drugs during dissolution. The stirring rod is usually located inside the dissolver and is in contact with the drugs. Moreover, the stirring rod is relatively large and has a large contact area with the drugs. Some viscous drugs may stick to the surface of the stirring rod, which can easily lead to waste. In addition, the surface temperature of the stirring rod may rise due to friction during the stirring process, which may damage the properties of the drugs. Therefore, we propose a drug dissolver for drug analysis. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a drug dissolver for drug analysis. By setting up a drive component, the drive motor drives the transmission shaft and the drive gear to rotate, thereby driving the driven gear and the driven shaft to rotate, and finally driving the main body of the drug dissolver to rotate. This can achieve a uniform mixing effect on the drugs inside the main body of the drug dissolver, and eliminate the need for a stirring paddle to stir the drugs. This prevents the drugs from sticking to the stirring paddle and causing waste, and also prevents the surface temperature of the stirring paddle from rising due to friction during the stirring process, which would damage the properties of the drugs.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A drug dissolver for drug analysis includes a drug dissolver body, a drive assembly externally connected to the drug dissolver body, and a temperature control assembly externally connected to the drug dissolver body. The drive assembly includes a base, a side plate fixedly connected to the upper end of the base, the side plates being symmetrically distributed left and right, a mounting bracket fixedly connected to the left end of the left side plate, a drive motor fixedly connected to the right end of the mounting bracket, a transmission shaft fixedly connected to the output end of the drive motor, a drive gear fixedly connected to the right end of the transmission shaft, and driven shafts fixedly connected to both ends of the main body of the drug dissolver, with a driven gear fixedly connected to the outside of the driven shaft on the left side, the drive gear meshing with the driven gear; By setting up a drive assembly, the drive motor drives the transmission shaft and the drive gear to rotate, which in turn drives the driven gear and the driven shaft to rotate, ultimately causing the main body of the drug dissolver to rotate. This allows for the uniform mixing of the drugs inside the main body of the drug dissolver, eliminating the need for a stirring paddle. This prevents the drugs from sticking to the stirring paddle and causing waste, and also prevents the surface temperature of the stirring paddle from rising due to friction during the stirring process, which could damage the properties of the drugs.

[0005] The temperature control assembly includes a temperature control chamber disposed inside the main body of the drug dissolver. A temperature control coil is fixedly connected inside the temperature control chamber. An inlet pipe is fixedly connected to the left end of the temperature control coil. A solenoid valve is fixedly connected to the outside of the inlet pipe. A medium tank is fixedly connected to the left end of the inlet pipe. A support rod is fixedly connected to the upper end of the base. A positioning ring is fixedly connected to the upper end of the support rod. A temperature sensor is fixedly embedded in the inner wall of the main body of the drug dissolver. A PLC controller is fixedly connected to the front end of the main body of the drug dissolver.

[0006] By setting up a temperature control component, a temperature sensor monitors the internal temperature of the drug dissolver and transmits the temperature signal to the PLC controller. When the temperature exceeds the range that the drug can withstand, the PLC controller controls the opening of solenoid valve one and water pump. The water pump draws external cooling medium into the medium tank, and finally enters the temperature control coil through the inlet pipe to cool the drug dissolver body.

[0007] Furthermore, a drain pipe is fixedly connected to the right end of the temperature control coil, and a second solenoid valve is fixedly connected to the outside of the drain pipe. The inlet pipe passes through the right driven shaft and is fixedly connected to the right driven shaft.

[0008] Furthermore, the liquid inlet pipe passes through the left driven shaft and is fixedly connected to the left driven shaft, and the medium tank passes through the positioning ring and is rotatably connected to the positioning ring.

[0009] Furthermore, both the driving gear and the driven gear are rotatably connected to the left-side side plate, and the driven shaft passes through the side plate and is rotatably connected to the side plate.

[0010] Furthermore, a water pump is fixedly connected to the upper end of the base, and a connecting pipe is fixedly connected to the output end of the water pump.

[0011] Furthermore, the connecting pipe is rotatably connected to the medium tank, and the input end of the water pump is fixedly connected to the input pipe.

[0012] Furthermore, a feed pipe is fixedly connected to the upper end of the main body of the drug dissolver, and a feed valve is fixedly connected to the outside of the feed pipe.

[0013] Furthermore, a discharge pipe is fixedly connected to the lower end of the main body of the drug dissolver, and a discharge valve is fixedly connected to the outside of the discharge pipe.

[0014] In summary, this utility model has the following beneficial effects: 1. By setting up a drive component, the drive motor drives the transmission shaft and the drive gear to rotate, which in turn drives the driven gear and the driven shaft to rotate, and finally drives the main body of the drug dissolver to rotate. This can achieve a uniform mixing effect on the drugs inside the main body of the drug dissolver, and there is no need for a stirring paddle to stir the drugs. This will prevent the drugs from sticking to the stirring paddle and causing waste, and also prevent the surface temperature of the stirring paddle from rising due to friction during the stirring process, which will damage the properties of the drugs. 2. By setting up a temperature control component, the temperature sensor monitors the internal temperature of the main body of the drug dissolver and transmits the temperature signal to the PLC controller. When the temperature exceeds the range that the drug can withstand, the PLC controller controls the opening of solenoid valve one and water pump. The water pump draws the external cooling medium into the medium tank, and finally enters the temperature control coil through the liquid inlet pipe to cool the main body of the drug dissolver.
