To achieve resource recycling and reduce environmental pollution, degreasing alkali solutions typically require regeneration or recycling. Traditionally, these waste liquids are often directly discharged, wasting resources and causing serious environmental pollution.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] See Figure 1 and Figure 2 The present application provides a detailed description of the degreasing alkali solution recycling system:

[0031] Combination Figure 1 The degreasing alkali solution recycling system includes a storage tank 2, a circulation system 3, an overflow system 4, and an oil removal system 5. The circulation system 3 connects the storage tank 2 and the immersion tank 1. The circulation system 3 includes a supply pipeline 31 and a return pipeline 32. The supply pipeline 31 is used to supply the alkali solution in the storage tank 2 to the immersion tank 1 to replace the alkali solution therein, ensuring the temperature and cleanliness of the alkali solution used for cleaning foil. The return pipeline 32 is used to filter and recover the alkali solution discharged or overflowing from the immersion tank 1 back into the storage tank 2.

[0032] The storage tank 2 is equipped with a first compartment 21 and a second compartment 22. The first compartment 21 is connected to the circulation system 3, and the alkaline solution in the first compartment 21 overflows into the second compartment 22. That is, the alkaline solution level in the upstream first compartment 21 is higher than the alkaline solution level in the downstream second compartment 22. The storage tank 2 can be divided into the first compartment 21 and the second compartment 22 by setting a partition. The overflow system 4 connects the first compartment 21 and the second compartment 22 and is used to transport the alkaline solution in the second compartment 22 back to the first compartment 21, ensuring that the alkaline solution in the first compartment 21 can continuously overflow into the second compartment 22. Floating matter, grease and other impurities floating on the alkaline solution in the first compartment 21 can overflow into the second compartment 22, ensuring that the alkaline solution in the first compartment 21 is clean for reuse.

[0033] In an embodiment not shown, the first compartment 21 and the second compartment 22 may be arranged in a pyramid shape, with the first compartment 21 located at the top of the second compartment 22, so that the alkaline solution in the first compartment 21 can overflow into the second compartment 22.

[0034] Combination Figure 2 The degreasing system 5 is used to remove grease floating on the surface of the alkaline solution in the second compartment 22 and transport the separated alkaline solution to the first compartment 21. The degreasing system 5 can extract floating matter, grease and other impurities overflowing into the second compartment 22 for separation and filtration, and transport the alkaline solution after removing impurities back to the first compartment 21. This enables the replacement of the alkaline solution in the immersion tank 1, ensuring the temperature and cleanliness of the alkaline solution in the immersion tank 1, and improving the cleaning effect on the foil. It can also clean up the recovered alkaline solution, reduce waste, and achieve a high recycling rate of alkaline solution.

The throttling component 42 is used to control the flow rate of the alkaline solution supplied to the first compartment 21, so as to ensure that the alkaline solution in the first compartment 21 can continuously overflow.

[0036] The supply pipeline 31 includes a booster pump 311 and a check valve 312. The check valve 312 is used to prevent the alkali solution from flowing back. The check valve 312 can be a one-way valve. A switch valve 313 is provided between the booster pump 311 and the first compartment 21. The booster pump 311 can transport the alkali solution in the first compartment to the immersion tank 1 for replacement. The return pipeline 32 includes a control valve and a first filter device 322 for filtering the discharged alkali solution and the overflowing alkali solution. The control valve can control the discharge of alkali solution in the immersion tank 1 and cooperate with the supply pipeline 31 to replace the alkali solution in the immersion tank 1.

[0037] Combination Figure 2 The oil removal system 5 includes a second check valve 51, an oil pump 52, an oil separator 53, and an oil collection tank 54. The oil pump 52 delivers alkaline solution to the oil separator 53, and the alkaline solution separated by the oil separator 53 is supplied to the first compartment 21, while the grease is delivered to the oil collection tank 54 for collection. This cleans the impurities floating on the surface of the alkaline solution in the second compartment 22, ensuring the quality of the recirculated alkaline solution.

[0038] The storage tank 2 is also equipped with a detection component located within compartment 21. This component detects the temperature and level of the alkaline solution within compartment 21. The detection component includes a level gauge and a thermometer to ensure the alkaline solution temperature supplied to the immersion tank 1 is the optimal cleaning temperature, while also ensuring that the alkaline solution level in compartment 21 can overflow. Both compartment 21 and compartment 22 may be equipped with drain pipes to discharge the alkaline solution from compartments 21 and 22.

[0039] In one embodiment, the liquid supply pipeline 31 is further provided with a conductivity measuring device 7, which is located between the immersion tank 1 and the check valve 312, and is used to detect the concentration of the alkali solution, enabling real-time monitoring of the concentration of the alkali solution supplied to the immersion tank 1.

[0040] It also includes a liquid supply system 9, which connects the liquid storage tank 2 and the circulation system 3, and is used to replenish the liquid storage tank 2 with alkali solution to ensure that the liquid level of alkali solution in the first compartment and the second compartment is not too low or too high; wherein, the liquid supply system may be equipped with a switch valve; the liquid supply system 9 can work with the conductivity measuring device 7 to adjust the concentration of alkali solution in the liquid storage tank 2.
