Technical Field

[0001] This utility model belongs to the field of plaster production technology, and in particular relates to a mixing and stirring device for the production of compound salicylic acid ointment. Background Technology

[0002] Compound salicylic acid ointment, a common topical preparation, is a cream-like external medicine mainly used to treat tinea corporis. Its production process requires mixing equipment to combine various raw materials. Chinese utility model patent CN217189369U discloses a raw material mixing device for medical ointment production. This device allows the drug solution to be dispersed and added into the mixing tank during mixing, ensuring more thorough mixing with the raw materials, saving mixing time, and exhibiting excellent stability throughout the process. Because the production process of compound salicylic acid ointment requires both uniformity and temperature stability, the above-mentioned raw material mixing equipment can only achieve stirring in one direction, which can easily lead to uneven mixing and excessively high local concentrations, directly affecting the quality of the ointment product. Moreover, the lack of heating function makes it difficult to maintain the temperature environment required during the stirring process. Excessive temperature fluctuations can not only cause denaturation of raw materials, but may also affect the consistency and shelf life of the ointment.

[0003] Therefore, there is an urgent need to improve the existing raw material mixing equipment for the production of medical ointments and to provide a mixing equipment for the production of compound salicylic acid ointment with good stirring effect and heating function. Utility Model Content

The heat-conducting part is made of copper and has multiple annular heating tubes fixedly sleeved on its outer side along the vertical direction. A heat insulation component is installed on the outer side of the annular heating tubes. The first stirring mechanism includes a first mixing component and several sets of scraper assemblies. The scraper assembly includes a bracket fixedly connected to the first mixing component. A rubber scraper is embedded and fixed on the side of the bracket away from the first mixing component. The rubber scraper slides against the inner wall of the processing tank.

The dispersing discs are provided with a serrated structure on their periphery, and an upper conical tooth is fixed on the outer side of the top end of the vertical shaft.

[0006] Preferably, the system also includes a feeding and discharging assembly, which includes a feeding pipe fixedly connected to the top of the processing tank and a discharging pipe fixedly connected to the bottom of the processing tank. A solenoid valve is installed on the discharging pipe to control the opening and closing of the discharging pipe.

[0007] Preferably, the bottom of the processing tank is fixed with a support assembly, which includes at least three support legs. The multiple support legs are evenly distributed on the bottom of the processing tank, and each support leg is provided with an anti-slip pad at its bottom end. The anti-slip pad is made of rubber.

[0010] Preferably, a drive mechanism is also included to control the linkage between the first stirring mechanism and the second stirring mechanism, wherein the rotation directions of the first stirring mechanism and the second stirring mechanism are always opposite to each other.

[0011] Preferably, the drive mechanism includes a drive motor fixedly mounted on the top of the processing tank, and a middle bevel gear fixedly mounted on the output shaft of the drive motor.
