[0024] Figure 1 An embodiment of a movable CIP station of the present invention is shown. The movable CIP station of this embodiment includes a mobile frame 1, on which a cleaning tank 2, a liquid supply pump 3, a liquid return pump 4, a liquid distribution tank 5, a metering pump 6, a heater 212 and an electrical box 9 are provided. The cleaning tank 2 is connected to a liquid supply pipe 21 and a liquid return pipe 22. The liquid supply pump 3 and the heater 212 are provided on the liquid supply pipe 21, the liquid return pump 4 is provided on the liquid return pipe 22, the liquid distribution tank 5 is provided between the cleaning tank 2 and the liquid supply pump 3, the metering pump 6 is located between the liquid distribution tank 5 and the liquid supply pipe 21, and a breather 28 is provided on the top of the cleaning tank 2 for maintaining normal pressure in the cleaning tank 2.

[0025] The cleaning modes of the mobile CIP station are as follows: 1) Purified water flushing: Add purified water to the cleaning tank 2, start the liquid supply pump 3, and the purified water in the cleaning tank 2 flows to the equipment to be cleaned through the liquid supply pipe 21 and is directly discharged after cleaning. 2) Acid or alkaline cleaning: If the equipment to be cleaned is difficult to clean and the cleaning liquid in the liquid preparation tank 5 (e.g., acid-base neutralizing liquid) is needed, the metering pump 6 is started, and the cleaning liquid in the liquid preparation tank 5 is pumped to the equipment to be cleaned by the liquid supply pump 3. Since the CIP station is mobile, in order to make the CIP station more compact, the capacity of the liquid preparation tank 5 is usually not set very large. At this time, there are two situations. If the capacity of the equipment to be cleaned is also very small, the cleaning liquid capacity in the liquid preparation tank 5 can meet the cleaning needs, and the equipment to be cleaned can be directly discharged after cleaning. If the capacity of the equipment to be cleaned is large, the cleaning liquid capacity in the liquid preparation tank 5 cannot meet the cleaning needs. The front-end cleaning liquid is directly discharged after cleaning, and the back-end cleaning liquid that meets the circulating cleaning standards is pumped to the cleaning tank 2 by the liquid return pump 4 through the return pipe 22 for circulation (at this time, there is no purified water in the cleaning tank 2, only the cleaning liquid is circulated) until it is discharged after cleaning is completed. If purified water is needed for cleaning later, purified water can be added to the cleaning tank 2. 3) Hot water washing: Turn on the heater 212 to achieve heating.

[0026] The movable CIP station integrates a cleaning tank 2 and a liquid preparation tank 5, and can switch between a purified water cleaning mode or an acid cleaning or alkaline cleaning mode according to actual cleaning requirements. The hot water cleaning mode can also be achieved by turning on the heater 212. The integration is high, and the three cleaning modes can cooperate with each other for cleaning, making the CIP station more functional. In addition, the cleaning liquid in the liquid preparation tank 5 can be circulated for cleaning to adapt to the cleaning of equipment to be cleaned of different capacities, which reduces the volume of the liquid preparation tank 5 to a certain extent, making the overall structure of the CIP station more compact and convenient to move.

[0027] Furthermore, in this embodiment, a detection assembly 7 for detecting the temperature and concentration of the liquid is provided on the return pipe 22. The detection assembly 7 is located between the return pump 4 and the cleaning tank 2. The return pipe 22 is connected to a discharge pipe 8, which is located between the detection assembly 7 and the cleaning tank 2. The return pipe 22 is provided with a first valve 221, and the discharge pipe 8 is provided with a second valve 81, which is located between the discharge pipe 8 and the cleaning tank 2. When the cleaning liquid circulates, the cleaning liquid is pumped into the return pipe 22 by the return pump 4. After detection by the detection assembly 7, if the cleaning liquid does not meet the circulation requirements, the first valve 221 is closed and the second valve 81 is opened, and the cleaning liquid is discharged through the discharge pipe 8. If the cleaning liquid meets the circulation requirements, the first valve 221 is opened and the second valve 81 is closed, and the cleaning liquid is pumped into the cleaning tank 2 for circulation, thereby ensuring that the pH and temperature requirements of the circulating cleaning liquid are met. Preferably, in this embodiment, the detection assembly 7 includes a third temperature sensor 71 and a conductivity sensor 72 to detect whether the temperature and conductivity of the cleaning liquid meet the circulation requirements.

[0028] Furthermore, in this embodiment, the heater 212 is provided at the rear end of the liquid outlet of the liquid supply pump 3. It can heat both the purified water and the cleaning liquid to improve the cleaning effect.

[0029] Furthermore, in this embodiment, a first temperature sensor 213 is provided on the liquid supply pipe 21 and is located at the rear end of the heater 212. The first temperature sensor 213 detects the temperature of the liquid after being heated by the heater 212.

[0030] Furthermore, in this embodiment, the liquid supply pipe 21 is connected to the top of the cleaning tank 2 via a first pipe 23. A third valve 231 is provided on the first pipe 23. A fourth valve 215 is also provided on the liquid supply pipe 21, located at the rear end of the first pipe 23. A second temperature sensor 24 is provided on the cleaning tank 2. Due to the limited heating power of the heater 212, if a higher liquid temperature (here, the liquid refers to purified water or cleaning water) is required, the fourth valve 215 can be closed first and the third valve 231 opened. This allows the heated liquid to enter the cleaning tank 2 through the first pipe 23 for circulation and heating. When the second temperature sensor 24 detects that the liquid temperature in the cleaning tank 2 has reached the required level, the third valve 231 is closed and the fourth valve 215 is opened. The liquid can then be cleaned normally, thus meeting the high-temperature cleaning requirements of pasteurization and other processes. This also reduces the size of the heater 212 to a certain extent, further making the overall structure of the CIP station more compact and easier to move.

[0031] Furthermore, in this embodiment, the top of the cleaning tank 2 is connected to a purified water inlet pipe 25, which is equipped with a fifth valve 251. A liquid level gauge 26 is also provided on the cleaning tank 2. Purified water is introduced through the purified water inlet pipe 25. The liquid level gauge 26 detects whether the purified water in the cleaning tank 2 meets the required level. The detection result controls the opening and closing of the fifth valve 251, ensuring that the purified water level in the cleaning tank 2 is maintained at an appropriate level.

[0032] Furthermore, in this embodiment, the liquid supply pipe 21 is connected to the liquid discharge pipe 8 via a second pipe 27. A sixth valve 271 is provided on the second pipe 27. A seventh valve 211 is provided on the liquid supply pipe 21. The seventh valve 211 is located between the second pipe 27 and the liquid supply pump 3. If it is necessary to drain the liquid in the cleaning tank 2 separately, the seventh valve 211 is closed and the sixth valve 271 is opened to achieve liquid discharge.

[0033] Furthermore, in this embodiment, a pressure sensor 214 is provided on the liquid supply pipe 21, and the pressure sensor 214 is located at the rear end of the liquid outlet of the liquid supply pump 3. The pressure sensor 214 is used to detect the liquid pressure to ensure that the cleaning pressure meets the requirements.

[0034] Furthermore, in this embodiment, the cleaning tank 2 is located at the top of the mobile frame 1, the liquid supply pump 3 and the liquid return pump 4 are located at the bottom of the mobile frame 1, and the liquid distribution tank 5 and the heater 212 are located between the mobile frame 1 and the liquid supply pump 3 and the liquid return pump 4. The structure is compact, and the liquid supply pump 3 and the liquid return pump 4 are located at the bottom of the mobile frame 1, which can reduce idling of the pump body and protect the pump body.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
