The tank body includes an inner tank 100 and an outer tank 200, and the height of the outer tank 200 is greater than that of the inner tank 100 to ensure that the liquid in the inner tank 100 will not overflow the tank body. The reaction liquid enters the inner tank 100 from the bottom of the inner tank 100. When the liquid is full, it will overflow from the upper edge of the inner tank 100 to the outer tank 200. The liquid blocking device is arranged on the top of the two side walls in the length direction of the outer tank 200 along the connection and is inclined toward the inner tank 100. Even if a small amount of liquid overflowing from the inner tank 100 splashes upward, it can be blocked by the liquid blocking device to prevent splashing into the adjacent tank body, thereby avoiding cross contamination caused by solution splashing.
[0031] According to an embodiment provided by the utility model, Figure 1 As shown, the liquid blocking device includes a liquid blocking plate 300.

The flow-reducing device is respectively arranged in the receiving space. One end of the flow-reducing device is connected to the outer wall of the inner tank 100, and the other end is connected to the inner wall of the outer tank 200.
[0034] In the present embodiment, the electroplating tank body is divided into an outer tank 200 and an inner tank 100, and the outer walls on both sides of the inner tank 100 are respectively combined with the inner walls on both sides of the outer tank 200 to form a receiving space.

[0035] Among them, the inner tank 100 in this embodiment is a reaction tank, and a liquid inlet is opened on the lower bottom of the inner tank 100. The liquid enters the inner tank 100 from the liquid inlet. When the liquid is full, it will overflow from the upper edge of the inner tank 100. Therefore, the above-mentioned slow flow device is arranged between the inner tank 100 and the outer tank 200. It can effectively avoid the splashing of the liquid overflowing from the inner tank 100 when falling, and it can effectively guide the liquid overflowing from the inner tank 100 to flow slowly to the bottom of the outer tank 200.

At the same time, preferably, the slow flow plate 400 extends in a stepped manner from one side of the inner tank 100 to the side of the outer tank 200, thereby ensuring that the liquid overflowing from the inner tank 100 can stay at the bottom of the outer tank 200 along the extension direction of the slow flow plate 400, thereby avoiding the liquid overflowing from the inner tank 100 from splashing into the adjacent tank body and causing cross contamination.
[0038] According to an embodiment provided by the utility model, Figure 1 and Figure 2 As shown, the flow control plate 400 includes a first plate body 401 and a second plate body 402.

That is, the plurality of slow flow holes 404 are arranged in multiple rows evenly along the extension direction of the second plate body 402, and the number of slow flow holes 404 arranged in each row is not limited here, and can be set according to the actual use of the slow flow plate 400.
[0049] According to an embodiment provided by the utility model, Figure 2 As shown, the diameter of each slow flow hole 404 is 5-8 mm.
[0050] In this embodiment, the diameter of the slow flow hole 404 is in the range of 5-8 mm.
[0051] Among them, preferably, the diameter of the slow flow holes 404 is selected to be 6 mm, and the multiple slow flow holes 404 are arranged at intervals on the second plate body 402, and can be set so that the number of odd-numbered rows from top to bottom is one less than the number of even-numbered rows, that is, the first row is provided with n slow flow holes 404, and the second row is provided with n+1 slow flow holes 404. Similarly, the third row is provided with n slow flow holes 404, and the fourth row is provided with n+1 slow flow holes 404, until the bottom of the second plate body 402.
[0052] The slow flow holes 404 arranged as above can make the slow flow plate 400 evenly covered with the slow flow holes 404 , and the slow flow through the slow flow holes 404 can also effectively reduce bubbles in the liquid.
