Description

Technical Field

[0001] This utility model belongs to the field of filling equipment technology, and in particular relates to a cleaning fluid drainage system for filling equipment. Background Technology

[0002] In the bottling of liquid foods such as beer and beverages, to improve hygiene or reduce cross-contamination of flavors between products, the inner surfaces of the bottling equipment that come into direct contact with the liquid product medium need to be thoroughly cleaned before and after a batch production, or when switching to another product. This is where an automated in-situ cleaning station (CIP) is introduced. This station provides the bottling equipment with cleaning media such as cold water, hot water, hot alkali, and hot acid. These media are supplied from the CIP station to the bottling machine and back, forming a cycle. According to the program settings, the CIP station and the bottling machine are connected in series for a period of time for cyclical cleaning. Typical cleaning processes include hot water → hot alkali → cold water, or hot water → hot alkali → hot water → hot acid → cold water, etc. After one medium reaches its cleaning time, the system automatically switches to the next medium. There are usually multiple media cleaning cycles, relying on cleaning solutions of specific concentrations and temperatures to ensure cleaning effectiveness. Furthermore, the cleaning process is selected specifically based on the product or the cleaning intensity.

[0003] The core elements for ensuring effective cleaning are the concentration, temperature, and contact time of the cleaning medium. However, in actual cleaning processes, after one medium completes its cleaning cycle and is switched to another, a mixture of the two media remains in the pipeline. The concentration and temperature of this mixture differ significantly from those of a single cleaning solution, directly impacting the cleaning effect. This is especially true for storage tanks in filling equipment, where this mixed medium can persist for a considerable period, significantly affecting the cleaning efficiency of the filling equipment. Incomplete cleaning poses a significant risk to liquid food production. Some manufacturers have discovered this problem during post-cleaning inspections and have attempted to extend the cleaning time to ensure overall effectiveness. However, this shortens production time and increases the cost per cleaning cycle. Utility Model Content

This end of the seventh pipe 29 is connected to a conventional second cleaning ball 31. The second cleaning ball 31 is used to clean the inside of the reflux tank 4.

[0021] During use, when the previous cleaning process is completed and the next cleaning process is about to begin, the filling valve 2 still has the cleaning cup sealing the filling valve port, ensuring that the valve port is in the open state and forming a return flow path. The inlet end of the first pneumatic three-way valve 9 connected to the cleaning fluid inflow pipe 15 is closed, and the inlet end of the first pneumatic three-way valve 9 connected to the compressed air input pipe 16 is opened. The outlet end of the second pneumatic three-way valve 10 connected to the fifth pipe 18 is opened, and the outlet end of the second pneumatic three-way valve 10 connected to the sixth pipe 28 is closed. The first pneumatic valve 6, the second pneumatic valve 20, and the fifth pneumatic valve 27 are all... With the first pneumatic three-way valve 9 in the open position, the third pneumatic valve 24, the fourth pneumatic valve 26, and the sixth pneumatic valve 30 remain closed. Centrifugal pump 21 starts when the liquid level is above the set level, and shuts down when the liquid level is below the set level, based on the liquid level measured by the second level gauge 14. Since the previous cleaning process has just ended, there will be medium in the return tank 4 that is above the set level, so centrifugal pump 21 should be in the running state. Because the first pneumatic three-way valve 9 is connected to the inlet of the compressed air input pipe 16, compressed air enters through the compressed air input pipe 16, the fourth pipe 17, and the fifth pipe 18. The first cleaning ball 19 enters the material storage tank 1, accelerating the discharge of the medium in the material storage tank 1. When the first level gauge 13 cannot detect the liquid level in the material storage tank 1, it indicates that there is only a small amount of medium in the material storage tank 1. At this time, the first pneumatic valve 6 is closed, allowing all the remaining medium in the material storage tank 1 to be discharged through the return channel of the filling valve 2. Due to the pressure provided by the compressed air, the medium in the return channel of the filling valve 2 will be discharged more thoroughly. At the same time, the liquid collection tank 3 is also emptied more quickly under the action of air pressure. The connection point between the liquid collection tank 3 and the third pipeline 8 is set at... The lowest point of the collection tank 3 ensures its emptying. When the second level gauge 14 cannot detect the liquid level in the return tank 4, the centrifugal pump 21 stops working, closes the second pneumatic valve 20, and opens the third pneumatic valve 24. Under the pressure of compressed air, the emptying of the return tank 4 is accelerated. At the same time, the connection point between the return tank 3 and the cleaning fluid return pipe 12 is also set at the lowest point of the return tank 3 to ensure its emptying. The discharge pipe 23 directly discharges the medium into the ditch, which can realize the rapid and thorough emptying of the filling equipment and effectively ensure the cleaning effect of the filling equipment.
