The communication port 11 extends vertically and has a certain length, which ensures the flow between the inside and outside of the containing cavity 23 and improves the accuracy of concentration detection.

[0047] As Figure 2 , 3, 4, 5, the protection structure 2 includes a straight protection 21, the protection 21 is connected to the side wall of the casing 1 vertically, the cross section of the protection 21 is Ω-shaped. The side wall of the casing 1 and the side of the protection 21 are respectively provided with vertically extending straight clamping groove 22 and clamping strip 12, the clamping strip 12 is slidably connected to the clamping groove 22.

[0048] Specifically, the protection structure 2 specifically covers the side wall of the casing 1 by the straight protection 21 to form the accommodating cavity 23, the cross section of the protection 21 can be designed according to specific needs, as long as it is in an arched state, it can install the detection assembly 4, in addition, the protection 21 is vertically arranged, that is, the accommodating cavity 23 extends vertically, which ensures that the liquid level of the whole tank liquid can be smoothly reflected in the accommodating cavity 23, and the related detection effect is ensured. The protection 21 and the casing 1 are fixed by the clamping groove 22 and the clamping strip 12, which has flexible detachability, and the insertion direction is vertical, which is convenient for adjusting the setting height. The lower side of the protection 21 is provided with a limiting boss 3, the lower end of the protection 21 abuts against the limiting boss 3, which limits the setting height, which is convenient for adjusting the setting height of the protection 21 according to the rising range of the tank liquid level, and the top surface of the limiting boss 3 closes the accommodating cavity 23 from the lower end, which realizes the protection in this direction.

[0049] As an optimization of the embodiment, in order to facilitate the adjustment of the setting height of the limiting boss 3, the limiting boss 3 is detachably connected with the casing 1, a plurality of insertion slots 13 are vertically distributed on the side wall of the casing 1, the tenon 31 of the limiting boss 3 is inserted into the insertion slot 13, and in addition, a marking line for marking height is arranged on the casing 1, and the marking line is vertically distributed on the side of the limiting boss 3.

The protective sleeve 1 is suspended, and the lower end of the protective sleeve 1 is circumferentially distributed with four supporting legs 17, which are detachably fixed with the tank bottom of the formation tank 5. A vertical partition plate 15 is arranged in the protective sleeve 1, which passes through the axis of the protective sleeve 1 and divides the inner cavity of the protective sleeve 1 into two sub-cavities 16. The outer side of the protective sleeve 1 is circumferentially and uniformly distributed with two groups of protection structures 2 and detection assemblies 4 (schematically shown in the figure) which are symmetrically arranged relative to the partition plate 15.

[0053] Specifically, the protective sleeve 1 is arranged in the middle of the formation tank 5, which ensures that the detection data of the detection assembly 4 can better represent the state of the overall tank liquid.

[0056] Specifically, the replenishment structure replenishes the formation tank 5 with tank solution through the tank solution filling pipe when the liquid level is too low, and adds pure water to the formation tank 5 through the pure water filling pipe when the concentration is too high, thereby controlling the concentration and level of the tank solution. Of course, a drain port is provided on the formation tank 5 to drain the tank solution when the liquid level is too high or under certain circumstances. A switch valve is provided on the drain port for control. The input power of the filling pipe is provided by a power pump assembly, which is controlled by the control panel and can make corresponding actions based on the corresponding detection data to achieve automatic control. Of course, especially when adjusting the concentration of the tank solution, the concentration data has a certain lag. After adding pure water, it takes a certain amount of time to achieve uniform concentration of the tank solution. When the concentration is close to the preset value, the addition of pure water should be stopped.

[0057] Specific working principle: The formation tank 5 is filled with tank solution. The concentration meter and level gauge detect the concentration and level of the tank solution in real time and send the detection data to the control panel. When the concentration of the tank solution is too high, pure water is added to the tank through the pure water injection pipe; when the level is too low, the same amount of tank solution is added to the tank through the tank solution injection pipe; when the level is too high, the drain valve is opened to discharge part of the tank solution to the appropriate level.
