Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a pharmaceutical mixing equipment. Background Technology

[0002] In the pharmaceutical industry, stirring equipment is a crucial unit operation device, widely used in the synthesis of active pharmaceutical ingredients, preparation of injection solutions, mixing of oral liquids, cultivation of biological agents, and the preparation of various pharmaceutical formulations such as emulsions, ointments, and suspensions. The core purpose of stirring is to achieve uniform mixing of materials, thoroughly mix medicinal materials and water, promote mass and heat transfer, and accelerate dissolution or chemical reactions, thereby ensuring the homogeneity of the final drug's components, quality stability, and medication safety.

[0003] However, conventional pharmaceutical mixing equipment in existing technologies generally suffers from problems such as low mixing efficiency, poor mixing effect, and uneven mixing in practical applications, making it difficult to meet the increasingly stringent requirements of modern pharmaceutical processes for mixing quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a pharmaceutical mixing device. By increasing the number and length of mixing sections and optimizing their distribution on the basis of conventional mixing sections, the medicinal materials and water can be mixed more thoroughly, effectively improving mixing efficiency. Furthermore, high-pressure gas can be passed through the mixing sections to break up fine materials and blow them off the inner wall of the tank, further enhancing mixing efficiency and effect, achieving a fully uniform mixing effect. This solves the technical problems of low mixing efficiency, poor mixing effect, and uneven mixing in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pharmaceutical mixing device includes a mixing tank. A shaft is coaxially rotatably mounted inside the mixing tank. A plurality of mixing sections are distributed on the circumferential outer wall of the shaft. The shaft and the mixing sections are both through pipes and are interconnected. An air inlet pipe is coaxially inserted into the shaft. The air inlet pipe has air holes matched at the positions of each mixing section. The air inlet end of the air inlet pipe is connected to an air supply device.

[0007] High-pressure gas is introduced into the inlet pipe by the gas supply device, then enters the stirring section of the central pipe structure through the air hole, and is sprayed into the interior of the stirring tank through the pipe opening of the stirring section to break up fine materials and blow off the materials on the inner wall of the stirring tank.

[0008] Preferably, the stirring section is lengthened.

[0009] Preferably, the stirring section is extended to the inner wall of the stirring tank.

[0010] Preferably, several of the stirring sections are distributed along the axial and circumferential directions of the shaft.

[0011] Preferably, the stirring section is made of sanitary stainless steel pipe.

[0012] Preferably, the upper end of the shaft extends out of the mixing tank body and the connection between the two is sealed and rotatably connected, and the upper end of the shaft is connected to a rotation drive assembly.

[0013] Preferably, the top of the mixing tank is welded with a cap, and the cap has a hole for sealing and rotating connection of the shaft.

[0014] Preferably, the rotation drive assembly includes a drive unit and a first bevel tooth coaxially connected to the output end of the drive unit, and also includes a second bevel tooth coaxially connected to the shaft, wherein the first bevel tooth and the second bevel tooth mesh and drive each other.

[0015] Preferably, the drive unit is a rotary motor.

[0016] Preferably, the drive unit and the first bevel tooth are arranged horizontally in the axial direction, and the second bevel tooth is arranged vertically in the axial direction.

[0017] Preferably, the upper end of the air inlet pipe extends out of the mixing tank body to connect to the air supply device.

[0018] Preferably, the mixing tank is provided with an upper feeding port at the top, a lower liquid outlet at the bottom, a side liquid inlet at the upper side, and a side liquid outlet at the lower side.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) Based on the conventional stirring section, this utility model increases the number and length of the stirring section and optimizes its distribution, so that the medicinal materials and water can be mixed more fully and effectively improve the stirring efficiency.

[0021] (2) This utility model sets both the shaft and the stirring part to be hollow tubes and the two are connected to each other. An air inlet pipe is inserted in the shaft to pass high pressure gas directly to the stirring part, thereby breaking up the fine materials in the tank and blowing off the fine materials on the inner wall of the tank, improving the stirring efficiency and enhancing the stirring effect, and achieving a fully uniform stirring and mixing effect.
