Description

Oxygen content detection monitoring device for pharmaceutical equipment Technical Field The utility model relates to the technical field of pharmaceutical equipment, in particular to an oxygen content detection and monitoring device for pharmaceutical equipment. Background Equipment in pharmaceutical plants, such as reaction kettles, centrifuges, etc., require control or monitoring of the oxygen content of the system during production due to the particular requirements (e.g., quality, safety, etc.) of the production project. For example, in the production process of a certain medicine, liquid is required to be dripped, the oxygen content in the kettle before each charging needs to be less than 0.5 percent, and the material can be charged, so that nitrogen purging is adopted in the kettle before the liquid is dripped, the oxygen content is monitored in real time, and the controllable charging process is ensured. However, at present, no single device for detecting and monitoring oxygen content exists in a pharmaceutical workshop, and the existing oxygen content detecting and monitoring devices are all oxygen content detecting components attached to certain pharmaceutical equipment and cannot be replaced for use. For example, chinese patent CN212655794U discloses a pharmaceutical fermentation tank capable of monitoring status at any time, the fermentation tank comprises a fermentation tank body, an observation window is arranged on the fermentation tank body, the observation window is of a rectangular structure, the height of the observation window is the same as the height of the main tank body of the fermentation tank body, the pharmaceutical fermentation tank further comprises an inner barrel, a heating pipe, a temperature sensor, a water level sensor, a condenser and a controller are arranged between the fermentation tank body and the inner barrel, and an oxygen content detection assembly is arranged on the inner side of the top of the fermentation tank body. The flexibility of using such oxygen content detection devices is relatively poor, and the maintenance and replacement costs are high, and improvement is needed.
