Description

Technical Field

[0001] The utility model relates to the technical field of medicine preparation, in particular to a reaction kettle device that is convenient for medicine preparation. Background Art

[0002] The reactor is a comprehensive reaction vessel. Its structure, functions, and accessories are designed according to the reaction conditions. From the initial feeding-reaction-discharging, the reactor can complete the pre-set reaction steps with a high degree of automation. The temperature, pressure, mechanical control, reactant / product concentration and other important parameters in the reaction process are strictly regulated. Currently, some pharmaceuticals require the use of reactors in the production process. Most traditional reactors only have a mixing structure inside.

[0003] In the prior art, the Chinese utility model application number: CN202222199118.4 discloses a reactor for preparing medicines, comprising a reactor body, an inner wall of the reactor body is embedded with a condenser tube, the feed port and the discharge port are fixed to and connected with the reactor body, valves are provided on the feed port and the discharge port, a stirring shaft is provided inside the reactor body, a plurality of connecting rods are provided on the stirring shaft, stirring blades are provided on the connecting rods, a gear ring is provided on the inner wall of the reactor body, a plug-in tube is provided on the reactor body, and a test tube is provided inside the plug-in tube; the stirring shaft can be driven to rotate by a provided servo motor, wherein when the stirring shaft rotates, the substance inside the reactor body is stirred through the stirring rod, wherein the stirring shaft drives the connecting rod to rotate during stirring, and when the connecting rod rotates, the gear and the gear ring are engaged and rotated, and when the gear rotates, the stirring blade is driven to rotate, thereby improving the stirring efficiency inside the reactor body;

[0004] Although the above technical solution can mix the medicine bottles, the contact between the ring gear and the gear and the medicine may affect the mixing of the medicine. When mixing powdered medicine, the direct contact between the gear and the ring gear may damage the medicine, making it inconvenient to clean the medicine and increasing the workload of cleaning the medicine. At the same time, directly placing the raw materials of the medicine into the reactor for stirring often makes it impossible to mix the raw materials of the medicine well. Therefore, we need to propose a reactor device that is convenient for mixing medicine. Utility Model Content
