Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical preparation technology, and more specifically, to a monitoring system for alkaline leakage in a pharmaceutical cleaning machine. Background Technology
[0002] In the pharmaceutical industry, equipment cleaning is crucial, especially given the extremely high safety and hygiene requirements for cleaning machines. Cleaning machines are commonly used to clean pharmaceutical equipment and containers, such as reaction vessels, mixers, and filling machines, to ensure product quality and safety. Pharmaceutical cleaning machines (such as CIP systems, Clean In-Place Systems) typically employ a circulating cleaning method, using chemical cleaning agents or water. This process includes multiple stages such as pre-cleaning, main cleaning, rinsing, and disinfection. Cleaning solution: The cleaning solution is generally water or a specific chemical solution used to remove residues from the equipment. The liquid circulates within the cleaning machine, cleaning the target equipment through nozzles, sprays, or other devices. Cleaning program: Cleaning machines typically operate within a series of preset programs, including control of parameters such as flow rate, temperature, and time, to ensure efficient cleaning. In the pharmaceutical industry, any residual contaminants, chemical cleaning agents, or moisture within any equipment or container can affect the quality of pharmaceutical products.
[0003] Cleaning machines require the addition of different chemical agents to clean various equipment. Therefore, any liquid leakage from the cleaning machine poses serious hygiene and safety hazards, and could even contaminate the entire production batch. In particular, alkaline solutions, due to their corrosive nature, are easily corroded at the cleaning machine's inlet, leading to leakage. Specifically, leakage can result in the loss of cleaning fluid, increased cleaning costs, reduced cleaning effectiveness, increased risk of cross-contamination, and impact on the quality of chemicals. Prolonged leakage can damage equipment, leading to increased maintenance costs and even production shutdowns.
[0004] In summary, how to provide a system for detecting alkali leakage is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a monitoring system for alkali leakage in pharmaceutical cleaning machines, which monitors the alkali inlet location to prevent alkali leakage and reduce costs and risks.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A pharmaceutical cleaning machine alkali leakage monitoring system includes:
[0008] An alkali solution inlet valve, which is connected to the cleaning machine via a pipeline;
[0009] The alkali storage barrel is used for storing alkali solution.
[0010] The alkali pump is used for conveying alkali solution in the alkali storage barrel to the cleaning machine.
[0011] The liquid inlet pipe is located between the alkali inlet valve and the alkali pump and is used for connecting the alkali inlet valve and the alkali pump.
[0012] The pressure sensor is installed on the liquid inlet pipe to monitor the pipeline pressure in the liquid inlet pipe.
[0013] The utility model further has:
[0014] The buzzer is installed on the pressure sensor.
[0015] The utility model further has that the alkali inlet valve adopts the electromagnetic valve.
[0016] The utility model further has that the alkali pump adopts the peristaltic pump.
[0017] The utility model further has:
[0018] The pressure sensor, the alkali inlet valve, the buzzer and the alkali pump are electrically connected with the controller.
[0019] The utility model further has that the liquid inlet pipe adopts stainless steel material.
[0020] The utility model further has:
[0021] The detection valve is located between the alkali inlet valve and the cleaning machine.
[0022] The utility model further has that the alkali storage barrel is equipped with the liquid level sensor.
[0023] The utility model further has that the pressure sensor adopts the ceramic capacitor pressure sensor.
[0024] The alkali leakage monitoring system for pharmaceutical cleaning machines provided by this utility model involves connecting the inlet pipe to the cleaning machine and installing the alkali inlet valve near the cleaning machine to control the entry of alkali into the machine. An alkali pump delivers alkali from a storage tank to the cleaning machine. Alkali to be used is added to the storage tank. When alkali needs to be added to the cleaning machine, the pump starts working, delivering alkali from the storage tank into the machine. If the alkali inlet valve is closed during use, but the pump operates, causing an increase in pressure in the inlet pipe, a pressure sensor will detect the abnormality. The device promptly alerts workers to take action. When it is necessary to periodically check for leakage risks at the alkali inlet valve, the valve is closed, the alkali pump operates, and the pressure in the inlet pipe increases. When the pump stops, the pressure in the inlet pipe remains constant. By observation, it is possible to determine whether there is a leakage at the alkali inlet valve. Therefore, this device fills the gap and deficiency in data monitoring of alkali pipelines in traditional cleaning machines. It can greatly extend the service life of alkali pipelines, reduce the pollution caused by alkali leakage to the clean area of pharmaceutical plants, ensure the standardized control of the cleaning process, and greatly improve the stability of drug production in pharmaceutical companies.

[0033] Optionally, in some embodiments, each pipeline in the system is made of corrosion-resistant material.
[0034] Optionally, in some embodiments, in order to achieve good warning effect, it further includes a buzzer, and the buzzer is installed on the pressure sensor 6, that is, the buzzer issues an alarm for the abnormal pressure detected by the pressure sensor 6, reminding the worker to observe and handle in time, improving the safety of system use.

[0036] Optionally, in some embodiments, the alkali solution pump 4 adopts a peristaltic pump, specifically, the peristaltic pump adopts a corrosion-resistant type. The corrosion-resistant peristaltic pump is a fluid conveying device specially used for conveying corrosive liquids. The core component, the pump tube, is usually made of special materials to ensure stable operation in strong acid, strong base, organic solvent and other corrosive media. For example, stainless steel such as 316L stainless steel or engineering plastics such as polypropylene (PP) can be used.
[0037] In order to further improve the automation degree of the whole system in use, in some embodiments, a controller is further included. The pressure sensor 6, the alkali solution inlet valve 1, the buzzer and the alkali solution pump 4 are all electrically connected with the controller, that is, the controller is used to control each component.

[0042] In order to further improve the accuracy of leakage detection, in some embodiments, a liquid level sensor 7 is arranged in the lye storage barrel 2, that is, in the process of detecting the liquid inlet pipe 5 and the lye inlet valve 1, after the lye pump 4 sends the lye into the liquid inlet pipe 5 to increase the pressure, in order to maintain the pressure, the lye pump 4 stops working, and when the pressure changes, the lye pump 4 works again, which causes the sensor value to change, so that the leakage problem can be detected more accurately, and the accuracy is improved.
