[0016] Preferably, the volume of the anti-suck tank is 1.3-3 times that of the cleaning tank.

[0017] The beneficial effects of the present application are as follows:

[0018] The present application is a general oxygen content detection monitoring device designed for the front-end equipment of a pharmaceutical workshop. The exhaust port of the pharmaceutical equipment is connected to the oxygen content detection monitoring device, so that the gas in the pharmaceutical equipment can be extracted for oxygen content detection. The device has strong applicability and can be applied to the entire pharmaceutical workshop. It is easy and fast to install and can achieve quick switching, which is very suitable for the application scene of quick switching of bulk drugs and intermediates in a multifunctional workshop. The main technical advantage is that:

[0019] 1. Convenient connection and strong versatility: the device can be conveniently connected with various pharmaceutical equipment, and the pharmaceutical equipment includes main reaction equipment (such as a reaction kettle) for chemical reaction. This good connection adaptability enables the oxygen content detection monitoring device to be widely applied to different pharmaceutical equipment systems, improving its versatility and applicability and facilitating integration in the pharmaceutical production process.

[0020] 2.

[0021] 3. The pre-treatment of the tail gas is beneficial to protect the subsequent equipment: the cleaning tank contains cleaning solvent, and is connected with the anti-suck tank through a cleaning pipe, and the end of the cleaning pipe extends below the cleaning solvent. This design makes the chemical reaction tail gas enter the anti-suck tank through the gas inlet pipe, and then enter the cleaning tank through the cleaning pipe, so that the tail gas can be fully cleaned by the cleaning solvent to remove impurities, corrosive substances and the like that may be contained in the tail gas. This not only helps to purify the tail gas, but also reduces the erosion of these harmful substances on the subsequent oxygen content detection components, thereby prolonging the service life of the oxygen content detection components and improving the accuracy of detection. Because the processing object of the pharmaceutical equipment usually contains corrosive gas and liquid, the cleaning process can effectively reduce the adverse effects on the detection components.

[0022] 5. The reasonable tail gas flow path can effectively improve the accuracy of oxygen detection: the gas inlet pipe, the cleaning pipe and the exhaust pipe form a path for the flow of chemical reaction tail gas. This design makes the tail gas orderly pass through each part of the device according to the established path, ensures smooth flow of the gas, avoids accumulation or chaotic flow of the gas in the device, and is beneficial to improve the efficiency and reliability of the entire oxygen content detection and monitoring process. At the same time, orderly tail gas flow also facilitates the treatment and detection of tail gas, ensuring the accuracy and stability of the oxygen detection results. BRIEF DESCRIPTION OF DRAWINGS
