[0037] When the pickling liquid is subsequently added to the PPH tank 1 through the liquid adding pipe 3, the newly added pickling liquid is confined in the isolation chamber 111 by the partition plate 13. At the same time, the pickling liquid in the lower cavity 12 of the PPH tank 1 is reciprocatingly pumped into the isolation chamber 111 by the circulating pump 21 to realize the circulation of the pickling liquid in the inner cavity of the PPH tank 1, accelerate the rapid and uniform mixing of the newly added pickling liquid and the existing pickling liquid in the PPH tank 1, and reduce the uneven overall concentration of the pickling liquid in the PPH tank 1 caused by the newly added liquid.
[0038] The partition plate 13 is welded and fixed to two opposite cavity walls of the PPH tank 1 at opposite sides, so that the partition plate 13 is stably supported in the upper cavity 11 of the PPH tank 1 .
[0039] Reference Figure 1 and Figure 2 The bottom end of the circulation pipe 2 extends into the lower cavity 12 of the PPH tank 1; the top end of the circulation pipe 2 extends into the isolation cavity 111 of the PPH tank 1. The circulation pipe 2 is horizontally arranged in the isolation cavity 111 and has a plurality of water outlet holes opened along its outer circumference along its own radial direction. Through the above arrangement, it is convenient for the circulation pump 21 to better pump the pickling liquid in the lower cavity 12 of the PPH tank 1 into the isolation cavity 111, and the isolation cavity 111 is quickly and evenly filled with the plurality of water outlet holes of the pipe body of the circulation pipe 2 located in the isolation cavity 111, thereby facilitating the circulation fluidity of the pickling liquid inside the PPH tank 1.
[0040] The liquid adding pipes 3 all extend into the isolation chamber 111 and a section of the liquid inlet pipe located in the isolation chamber 111 is bent downward to facilitate the subsequent newly added pickling solution to flow into the isolation chamber 111 better.

The cleaning pipe 4 and the drain pipe 5 are located on the opposite side walls of the PPH tank 1, and the drain pipe 5 is located at the bottom of the PPH tank 1. Through the above arrangement, clean water can be subsequently injected into the inner cavity of the PPH tank 1 through the cleaning pipe 4 to rinse and clean the inner cavity of the PPH tank 1. The arrangement of the drain pipe 5 facilitates the wastewater generated by the subsequent cleaning of the PPH tank 1 to be discharged through the drain pipe 5 in time. The bottom wall 10 of the PPH tank 1 is arranged obliquely, and the inclined lower end of the bottom wall 10 extends to the pipe mouth of the drain pipe 5, so that the sediment accumulated on the bottom wall 10 of the PPH tank 1 can be discharged from the drain pipe 5 with the wastewater.

The setting of the overflow pipe 6 facilitates the subsequent excess pickling liquid to be discharged in time through the overflow pipe 6, reducing the situation where the pickling liquid overflows due to excessive addition of new pickling liquid.
[0043] A support plate 14 is vertically welded on the inner wall of the PPH tank 1 , and the overflow pipe 6 is passed through and fixed to the support plate 14 , so that the overflow pipe 6 can be more firmly installed in the PPH tank 1 .
[0044] The implementation principle of the first embodiment is as follows: during the use of the PPH tank 1, the circulating pump 21 on the circulating pipe 2 reciprocates to pump the pickling liquid in the lower cavity 12 of the PPH tank 1 into the isolation cavity 111; subsequently, new pickling liquid is added to the isolation cavity 111 through the liquid adding pipe 3, and the partition plate 13 is used to limit the newly added pickling liquid from flowing to the pickling cavity 112 of the upper cavity 11. At the same time, the circulating pump 21 is used to drive the circulation flow between the pickling liquids in the lower cavity 12 and the isolation cavity 111, so that the newly added pickling liquid is quickly mixed with the existing pickling liquid, thereby reducing the situation where the newly added pickling liquid causes uneven concentration of the pickling liquid in the PPH tank 1, which affects the pickling processing of the aluminum foil, and is beneficial to improving the concentration stability and uniformity of the pickling liquid in the PPH tank 1.

When the PPH tank barrel 1 is subsequently cleaned, the partition plate 13 can be lifted out of the PPH tank barrel 1 to better flush the inner cavity wall of the PPH tank barrel 1.
[0048] A plurality of eyebolts are threadedly connected to the top of the partition plate 13. When the partition plate 13 is subsequently disassembled and assembled, the partition plate 13 can be lifted out of or lowered into the PPH tank 1 through the eyebolts.
[0049] Reference Figure 3 and Figure 4 , the bottom end of the circulation pipe 2 extends into the lower cavity 12 of the PPH tank 1, and one end of the circulation pipe 2 located in the lower cavity 12 is vertically connected to a connecting pipe 22, which is arranged horizontally and located on one side of the lower cavity 12; the outer periphery of the connecting pipe 22 is evenly and vertically connected to a number of pumping pipes 23 along its own length direction, and the radial direction of the pumping pipe 23 is perpendicular to the radial direction of the connecting pipe 22, and the end of the pumping pipe 23 away from the connecting pipe 22 extends to the other side of the lower cavity 12, and the outer periphery of the pumping pipe 23 is provided with a number of water inlet holes along its own radial direction.
