Description

Technical Field

[0001] The utility model relates to the technical field of CIP cleaning, and particularly to a leak detection and splash prevention CIP valve array cleaning distribution station. Background Art

[0002] In the food, beverage and pharmaceutical industries, the CIP (Clean-In-Place) system is a key component to ensure the hygiene of the production line. In particular, in fermentation and beverage production, the aseptic control of equipment pipelines is crucial for CIP cleaning. To prevent cross-contamination between equipment, regular cleaning and sterilization are essential. The CIP system can complete cleaning and disinfection by automatically circulating and spraying cleaning liquid without disassembling the equipment, greatly improving production efficiency, reducing downtime, and helping to maintain high standards of hygiene. However, despite the many advantages brought by the CIP system, there is still a problem that cannot be ignored in its practical application - leakage and splashing.

[0003] During the CIP cleaning process, due to the action of high-pressure liquid, valves, pipe joints or seals in the equipment may leak due to wear, aging or manufacturing defects. Once leakage occurs, it will not only cause waste of cleaning liquid and increase production costs, but more importantly, the leaked liquid may pose a safety hazard to operators. In particular, the liquid splashing under high pressure may cause serious physical injuries such as burns or eye injuries. In addition, leakage may also cause cross-contamination and pose a threat to product quality, especially when different types of cleaning liquids or products are mixed in the production line.

[0004] To solve the problems of leakage and splashing, traditional CIP systems usually rely on regular maintenance inspections and seal replacements, but this cannot detect leakage in real time. Leakage is often only discovered when it has caused a certain impact, and it is too late to take measures at this time. Therefore, developing a CIP system that can immediately detect leakage and effectively prevent liquid splashing has become an urgent need to improve production safety and efficiency.

[0035] In the food, beverage and pharmaceutical industries, the CIP (Clean-In-Place) system is a key component to ensure the hygiene of the production line. In particular, in fermentation and beverage production, the aseptic control of equipment pipelines is the key to CIP cleaning. To prevent cross-contamination between equipment, regular cleaning and sterilization are essential. The CIP system completes cleaning and disinfection by automatically circulating and spraying cleaning liquid without the need to disassemble the equipment, greatly improving production efficiency, reducing downtime, and helping to maintain high standards of hygiene conditions. However, despite the many advantages brought by the CIP system, there is still a problem that cannot be ignored in its practical application - leakage and splashing.

[0036] During the CIP cleaning process, due to the action of high-pressure liquid, valves, pipe joints or seals in the equipment may leak due to wear, aging or manufacturing defects. Once leakage occurs, it will not only cause waste of cleaning liquid and increase production costs, but more importantly, the leaked liquid may pose a safety hazard to operators. Especially, the liquid splashing under high pressure may cause serious physical injuries such as burns or eye injuries. In addition, leakage may also cause cross-contamination and pose a threat to product quality, especially when different types of cleaning liquids or products are mixed in the production line.

[0037] To solve the problems of leakage and splashing, traditional CIP systems usually rely on regular maintenance inspections and seal replacements, but this cannot detect leakage in real time. Leakage is often only discovered when it has already caused a certain impact, and it is too late to take measures at this time. Therefore, developing a CIP system that can immediately detect leakage and effectively prevent liquid splashing has become an urgent need to improve production safety and efficiency.

[0038] For this reason, as Figure 1 and Figure 3As shown in the figure, this is a leak detection and anti-splash CIP valve array cleaning distribution station proposed by the present utility model, which includes a base 100 and an infusion assembly. Among them, the infusion assembly includes a centrifugal pump conveyor 200 and a plurality of double-seat anti-mixing valves 300. The plurality of double-seat anti-mixing valves 300 are linearly arranged at intervals. Moreover, the centrifugal pump conveyor 200 is connected to the double-seat anti-mixing valves 300 and conveys liquid to the double-seat anti-mixing valves 300. The plurality of double-seat anti-mixing valves 300 independently distribute liquid to the equipment to be cleaned. It should be noted that the opening of each double-seat anti-mixing valve 300 is automatically controlled by a computer, and the pipelines and valves can be independently cleaned by means of a CIP program, which can minimize the cleaning dead corners. Specifically, the output end of the double-seat anti-mixing valve 300 is connected with a discharge pipe 320, which can be connected to the equipment to be cleaned to clean it. In addition, in the valve closed position, there is a double-seal ring seal between the two pipelines, and the phenomenon of liquid leaking from one pipeline to another can be completely eliminated, avoiding cross-contamination. When one of the seal rings is damaged and leaks, the leaked material can be discharged to the outside through the leakage chamber of the valve without polluting the other channel. Further, the leakage chamber is connected with a leak detection pipe 310. The base 100 is provided with a water receiving tank 101. The splash guard 110 covers the end face of the water receiving tank 101. And, the splash guard 110 is provided with a positioning hole 1101 corresponding to the leak detection pipe 310. The end of the leak detection pipe 310 is inserted into the water receiving tank 101 through the positioning hole 1101. The splash guard 110 is made of a transparent material to observe the internal condition of the water receiving tank 101. Optionally, the splash guard 110 is an acrylic plate, which not only provides good transparency for observing the internal condition of the water receiving tank 101, but also the acrylic plate has high impact resistance and chemical resistance, and can maintain its performance in a harsh industrial environment, ensuring long-term reliability and safety. The overall integrates the functions of leak detection and splash protection, significantly improving the safety and efficiency of production lines in the food, beverage and pharmaceutical industries. Among them, by setting a leakage chamber in the double-seat anti-mixing valve 300 and connecting it with the leak detection pipe 310, the ability of instant leak detection is realized. Once a leak occurs, the liquid will be guided to the leak detection pipe 310 and finally flow into the water receiving tank 101 located on the base 100. This process ensures that any leaked cleaning liquid will not be directly discharged into the environment, avoiding waste of resources, and is also conducive to discovering problems at the initial stage of the seal ring breakage of the double-seat anti-mixing valve 300 and replacing the seal ring in time. At the same time, the splash guard 110 not only blocks the splash of the leaked liquid and will not accidentally injure the inspection operator, but also due to its transparent material, allows the operator to directly observe the internal situation of the water receiving tank 101, instantly discover and respond to the leak event, achieving multiple goals of instant leak detection, effective splash protection, improved operation safety, optimized production efficiency and strengthened hygiene standards.In addition, a sewage outlet 1011 is provided on the bottom wall of the water receiving tank 101 to discharge the liquid in the water receiving tank 101, ensuring that the water receiving tank 101 will not overflow or be secondarily polluted due to liquid accumulation. At the same time, the cleaning process is simplified, facilitating regular cleaning and maintenance, and maintaining the hygiene standards and operation efficiency of the system.

[0039] In some embodiments of the present utility model, the splash guard 110 is detachably installed on the base 100, providing great flexibility and convenience. The splash guard 110 can be easily removed for cleaning or replacement, reducing the maintenance cost and shortening the downtime of the production line, ensuring continuous high-efficiency operation. Specifically, referring to Figure 1 and Figure 2 , a plurality of support plates 120 are fixedly installed on the side wall of the water receiving tank 101. The support plates 120 are located below the splash guard 110. The plurality of support plates 120 cooperate to support the periphery of the bottom wall of the splash guard 110, ensuring the stability of the splash guard 110. Moreover, the splash guard 110 can also be conveniently disassembled and assembled from above, facilitating the operation of the operator. Further, the aperture of the positioning hole 1101 is equal to the outer diameter of the leak detection material pipe 310, ensuring that the leak detection material pipe 310 can be tightly and smoothly inserted into the positioning hole 1101, reducing the possibility of leakage. At the same time, it is also convenient for installation and disassembly, ensuring the reliability and ease of use of the leak detection system. Referring again to Figure 3 , there are a plurality of positioning holes 1101. The plurality of positioning holes 1101 are arranged at intervals along the length direction of the splash guard 110 in the middle of the splash guard 110. Furthermore, the leak detection material pipe 310 inserted into the splash guard 110 is located in the middle of the splash guard 110, facilitating the inspection operator to observe the liquid outlet condition of the leak detection material pipe 310 and reducing the interference of the support plate 120 on the leak detection material pipe 310. Optionally, there are six double-seat anti-mixing valves 300 and six positioning holes 1101, and the leak detection material pipes 310 are inserted into the positioning holes 1101 in one-to-one correspondence.

[0040] Referring again to Figure 1In some embodiments of the utility model, the centrifugal pump conveyor 200 is connected to the double-seat anti-mixing valve 300 through a delivery pipe, and the delivery pipe includes a connecting section 410 and a liquid inlet section 420. One end of the connecting section 410 is connected to the output end of the centrifugal pump conveyor 200 through a first connecting joint 411, and the other end of the connecting section 410 is connected to the liquid inlet section 420 through a second connecting joint 412. Optionally, the first connecting joint 411 and the second connecting joint 412 are both quick-connect joints, which are convenient for disassembly and connection, and can be used to segment the delivery pipe, which has better flexibility. In addition, the input ends of multiple double-seat anti-mixing valves 300 are all connected to the liquid inlet section 420, and the pipeline structure is simple and easy to use. Furthermore, a check valve 421 is installed at the connection between the connecting section 410 and the liquid inlet section 420 to prevent the liquid from flowing back in the liquid inlet section 420, avoid the reverse flow that may occur during the cleaning process, ensure the directional flow of the cleaning liquid, and improve the efficiency and safety of cleaning.

[0041] Furthermore, the delivery pipe includes an emptying section 430, and the emptying section 430 is connected to the end of the liquid inlet section 420 away from the connecting section 410 through a third connecting joint 431. Similarly, the third connecting joint 431 is a quick-connect joint, which is easy to disassemble and connect, and can be used to divide the delivery pipe into sections, which is more flexible to use. In addition, an emptying valve 422 is provided at the connection between the emptying section 430 and the liquid inlet section 420 to empty the liquid in the liquid inlet section 420. It is allowed to empty the liquid in the liquid inlet section 420 when not in use or after use, which reduces corrosion or bacterial growth caused by residual liquid, prolongs the service life of the system, and facilitates the preparation and maintenance of the system before startup.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
