[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5, the present utility model provides a technical solution: a circulating water automatic acid adding device, including a circulating water tank body 1, a control box 101 and an acid storage tank 2. The top of the circulating water tank body 1 is connected with a control box 101 and an acid adding pipe 204. The top of the acid adding pipe 204 is connected with a drain acid pipe 202 through a metering pump body 203. The top of the drain acid pipe 202 is connected with the acid storage tank 2. One side of the acid storage tank 2 is provided with a drain acid pump body 201. The bottom of the drain acid pump body 201 is inserted through the drain acid pipe 202 through a acid suction pipe. A pH meter body 3 is installed inside the circulating water tank body 1;

[0023] A driving motor 4 is installed on the top of the acid storage tank 2. The output end at the bottom of the driving motor 4 is connected with one end of a driving rod 401 through a coupling. The other end of the driving rod 401 is rotationally connected with an installation pipe 405 through a bearing seat, and the top of the installation pipe 405 is connected with the drain acid pipe 202. A stirring frame 402 is welded on the outer side of the driving rod 401, and a stirring rod 403 is welded inside the stirring frame 402. The stirring rod 403 is arranged in a wave shape. A movable plug 404 is arranged on the outer side of the driving rod 401. External thread layers 407 are connected to the outer sides of the driving rod 401 and the movable plug 404. Internal thread layers 406 are connected to the inside of the installation pipe 405 and the movable plug 404, and the external thread layer 407 is threadedly connected with the adjacent internal thread layer 406.

[0024] During specific implementation, to avoid stratification and precipitation of the solution inside the acid storage tank 2 after long-term static settlement, when the pH meter body 3 detects that the pH of the solution inside the circulating water tank body 1 is relatively low, the control box 101 will control the driving motor 4 to drive the driving rod 401 to rotate through the coupling at the output end. When the driving rod 401 rotates, it will drive the stirring frame 402 and the stirring rod 403 to rotate, and mix and stir the solution inside the acid storage tank 2;

[0025] Meanwhile, the external thread layer 407 on the outer side of the driving rod 401 will be in threaded engagement with the internal thread layer 406 inside the movable plug 404 under the action of the threads of the external thread layer 407 on the outer side of the movable plug 404 and the internal thread layer 406 inside the acid discharge pipe 202, thereby driving the movable plug 404 to move downward until the movable plug 404 completely enters the installation pipe 405. At this time, the liquid discharge channel on the upper side of the acid discharge pipe 202 is opened, and the control box 101 can control the corresponding metering pump body 203 to quantitatively extract the solution in the acid discharge pipe 202 and discharge the solution to the inside of the circulating water tank body 1 through the acid adding pipe 204 for acid adjustment work. Among them, the wavy setting of the stirring rod 403 can effectively interrupt the continuity of the rotation of the solution and enhance the mixing effect. This automatic circulating water acid adding device can fully mix the solution in the acid storage tank 2 before adding acid, and can open the liquid discharge channel only after the solution is evenly mixed, avoiding the problem of poor solution effect caused by uneven solution mixing, and can effectively improve the acid adding efficiency.

[0026] Refer to Figure 1 and Figure 2 It can be seen that the bottom of the acid adding pipe 204 is connected to one end of the connecting hose 5, the other end of the connecting hose 5 is connected to the spray pipe 501, the bottom of the spray pipe 501 is equidistantly connected with spray heads 502, both ends of the spray pipe 501 are connected to the rotating rod 504 through connecting pipes 503, one end of the rotating rod 504 is rotatably connected to the circulating water tank body 1 through a bearing seat, and a servo motor 505 is installed on one side of the circulating water tank body 1. The output end of the servo motor 505 is connected to the rotating rod 504 through a coupling.

[0027] During specific implementation, to facilitate better mixing of the solution in the acid storage tank 2 and the solution in the circulating water tank body 1, when the spray pipe 501 and the spray heads 502 are spraying, the servo motor 505 is started. The servo motor 505 drives the rotating rod 504 to rotate and swing through the coupling at the output end, thereby driving the spray pipe 501 to stir the solution in the circulating water tank body 1, making the two solutions evenly mixed and improving the adjustment efficiency. At the same time, when the spray pipe 501 and the spray heads 502 need to be repaired and replaced, they can be rotated to the top of the circulating water tank body 1 through the servo motor 505, facilitating the repair and replacement work. This automatic circulating water acid adding device can swing when spraying the solution, improve the mixing efficiency of the solution, promote the mutual mixing of the solution, and achieve rapid adjustment of the pH inside the circulating water tank body 1.

[0028] In summary, when using this automatic acid adding device for circulating water, the pH meter body 3 monitors the solution inside the circulating water tank body 1 in real time, and displays the detection result on the pH meter body 3. The pH meter body 3 displays the pH value and converts the pH value into a signal and transmits it to the control box 101. The control box 101 controls the start of the metering pump body 203 and the drive motor 4 according to the received pH signal, adds the acid solution in the acid storage tank 2 into the circulating water to adjust the water quality. After the circulating water is adjusted by the acid solution, the pH meter body 3 displays the latest detection result collected on the pH meter body 3, and converts it into a signal by the pH meter body 3 and transmits it to the control box 101. After receiving this signal, the control box 101 can control the metering pump body 203 and the drive motor 4 to close. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
