Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleaning agent addition devices, specifically a cleaning agent addition device for dairy membrane filtration equipment. Background Technology
[0002] Dairy membrane filtration equipment, commonly used in the food industry, requires a variety of cleaning agents that must be added in a precise and quantitative manner in a specified order during cleaning due to the special requirements of the equipment.
[0003] The specific reason is that membrane elements in membrane filtration equipment cannot withstand strong acids and alkalis, and require a suitable pH range. To prevent corrosion damage to the membrane elements, cleaning agents need to be added quantitatively and at a slow, even rate to prevent excessive local acidity or alkalinity in the cleaning solution, which could damage the membrane core. Since dairy membranes require a variety of cleaning agents, typically 4-5 types, current technology uses manual addition, which is cumbersome, labor-intensive, and prone to errors. Furthermore, manual handling of acid and alkali cleaning agents poses significant safety risks and no longer meets the requirements of this application. Therefore, an improved technology is urgently needed to solve the aforementioned problems in the existing technology. Utility Model Content

[0021] The cleaning agent switching mechanism includes a frame 10, a cleaning agent tank 11, and an electric adding valve 12. The upper surface of the frame 10 is open and has several partitions 13 inside. Several cavities 14 are set inside the frame 10 through the partitions 13. There are two rows of cavities 14 located below the connecting pipe 7. Two rows of supports 16 are set on the upper surface of the frame 10. The connecting pipe 7 is supported on the upper part of the supports 16. The supports 16 are used to support and fix the connecting pipe 7. The cleaning agent tank 11 is set in the cavity 14. Both sides of the frame 10 and each cavity 14 are open, so that the cleaning agent tank 11 can be put into or taken out of the frame 10 from the side openings. There are several electric adding valves 12, which correspond one-to-one with the cavities 14. The outlet end of the electric adding valve 12 is connected to the bypass interface of the corresponding connecting pipe 7. The inlet end of the electric adding valve 12 is connected to a hose 15. The bottom of the hose 15 is set in the corresponding cleaning agent tank 11.
[0022] Installation method and operating principle: Install multiple electric adding valves 12 on the bypass port at the bottom of the connecting pipe 7. Install two connecting pipes 7 on the upper surface of the frame 10 through brackets 16, with the electric adding valves 12 facing downwards. Then connect the two ends of the two connecting pipes 7 to the first tee connector 6 and the second tee connector 8, respectively. The first tee connector 6 is also connected to the outlet end of the electric water valve 2. The inlet end of the electric water valve 2 is connected to the outlet end of the manual valve 1 through a pipe. The inlet end of the manual valve 1 is connected to the soft water inlet pipe 17.

In use, first open the manual valve 1 and the electric water valve 2, and close the drain valve 4 to fill the entire pipeline with pure water. After a few seconds, the flow meter 5 detects the flow rate, close the electric water valve 2, open the electric addition valve 12 for the corresponding cleaning agent, keep the drain valve 4 closed, and start the pneumatic diaphragm pump 3. The pneumatic diaphragm pump 3 begins to draw cleaning agent from the cleaning agent tank 11, and the flow meter 5 begins to accumulate the volume of cleaning agent passing through. The pneumatic diaphragm pump adds cleaning agent intermittently and stably according to the switching time set by the PLC. When the accumulated volume reaches the set value, close the corresponding electric addition valve 12 and the pneumatic diaphragm pump 3, open the electric water valve 2, and start pushing the cleaning agent with water to complete the quantitative addition. The membrane filtration equipment begins cleaning. When the cleaning time is up, open the drain valve 4 to push the cleaning solution to the ground. After the ground is drained, proceed with the next cleaning step according to the cleaning formula. This utility model has a reasonable structure. The electric addition valve 12 at the bottom of the connecting pipe 7 opens and closes the corresponding cleaning agent pipeline. The corresponding cleaning agent is then extracted by the pneumatic diaphragm pump 3 and pushed by the electric water valve 2. The cleaning agent can be added quantitatively in a specified order, thereby cleaning the dairy membrane filtration equipment. This saves labor, eliminates risks, and has higher precision than manual operation. At the same time, the cleaning agent tank 11 is placed in the frame 10. The frame 10 has two rows of cavities 14 set inside by the partition 13. Two connecting pipes 7 are set on the upper surface of the frame 10, which is more compact than the single-row arrangement and saves space in the length direction.
