Description

Technical Field

[0001] This utility model relates to the field of chemical pharmaceutical preparation and drying technology, and in particular to a chemical pharmaceutical preparation and drying device. Background Technology

[0002] Chemical drugs are medicines produced through chemical synthesis or extraction of natural substances. They are mainly used to treat, prevent, or diagnose diseases. These drugs are typically composed of molecules with specific chemical structures and activities, capable of interacting with the body's biomolecules to achieve the purpose of treating, preventing, or diagnosing diseases.

[0003] An existing chemical preparation mixing and drying device (publication number: CN220771804U) uses a mixing structure that integrates a spiral feeding and a rotary stirring structure. During the mixing process, the mixing structure transports the material from the bottom upwards. However, the heat is transferred to the material inside the mixing chamber through a heat-conducting protective plate, which can easily lead to uneven heat distribution within the drying chamber. This can result in localized excessively high or low temperatures, which is not conducive to the effective preparation of chemicals and thus reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a chemical preparation drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chemical pharmaceutical preparation drying device includes a base and a drying cylinder. An inner cylinder is fixedly installed inside the drying cylinder, and threaded holes are evenly spaced on the inner cylinder. A spiral groove is formed on the inner wall of the base. A mixing rod is installed at the center of the base. A conical guide post is fixedly installed at the top of the mixing rod, and a flow guide groove is formed on the conical guide post. A stirring blade is fixedly installed on the mixing rod. A motor is installed at the bottom of the drying cylinder via fasteners. The motor is fixedly connected to the mixing rod via an output shaft, which passes through the bottom of the drying cylinder. A filter plate is embedded in the top of the drying cylinder. A fixed box is fixedly installed at the upper end of the drying cylinder, and a fan device is fixedly installed inside the fixed box. A heating wire is located below the fan device.

[0007] As a further embodiment of this utility model, a support column is fixedly provided between the side wall of the drying cylinder and the base, the support columns are symmetrically distributed on the base, and a feed pipe is fixedly provided at the center of the top of the drying cylinder.

[0008] As a further embodiment of this utility model, a feeding hopper is fixedly provided at the other end of the feeding pipe, a one-way valve is fixedly installed on the feeding pipe, and a discharge pipe is fixedly provided at the bottom of the drying cylinder.

[0009] As a further embodiment of this utility model, a one-way valve is fixedly installed on the discharge pipe, and the stirring blades are evenly distributed on the mixing rod.

[0010] As a further embodiment of this utility model, the heating wire is fixedly connected to the inside of the fixed box, and an air outlet pipe is fixedly provided on one side of the fixed box.

[0011] As a further embodiment of this utility model, the other end of the air outlet pipe is connected through the top of the drying cylinder, and the air outlet pipes are evenly distributed on the fixed box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When preparing the chemicals, firstly, open one-way valve two to pour the chemicals into the drying cylinder. Simultaneously start the motor, which drives the mixing rod to rotate via the output shaft. This rotation also drives the conical guide column, which disperses the incoming chemicals, preventing clumping and accumulation from vertical drop. The mixing rod then drives multiple sets of stirring blades to agitate the chemicals. A "V"-shaped guide groove is provided on the conical guide column, guiding the airflow upwards and carrying away moisture from the chemicals, which is then discharged through the filter plate. Next, turn on the fan and connect the heating wire to the power supply, heating the cold air generated by the fan. The hot air then enters the drying cylinder through two sets of outlet pipes. Guided by spiral grooves, the hot air circulates back and forth at different positions within the drying cylinder. Several threaded holes provide more flow channels for the hot air, improving its uniformity and coverage throughout the drying chamber, ensuring effective drying. Finally, open one-way valve one to discharge and collect the dried chemicals through the discharge pipe. Attached Figure Description

The hot air then enters the interior of the drying cylinder 2 through two sets of air outlet pipes 202. Under the guidance of the spiral groove 5, the hot air flows back and forth at different positions inside the drying cylinder 2, and through several threaded holes 801, more flow channels are provided for the hot air, thereby improving the uniformity and coverage of the hot air in the entire drying chamber, reducing airflow dead zones, and ensuring that the heat comes into full contact with the medicine, thus ensuring the drying effect of the medicine.

The conical guide column 106 disperses the incoming chemical, and the mixing rod 203 drives multiple sets of stirring blades 301 to stir the chemical. Furthermore, a "V"-shaped guide groove 303 is provided on the conical guide column 106. Under the guidance of the 3, the airflow can be guided upward, allowing the moisture contained in the medicine to be discharged from the upper filter plate 6. Then, the fan device 7 is turned on, and the heating wire 8 is connected to the power supply, so that the heating wire 8 heats the cold air generated by the fan device 7.
