It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1-5As shown in the figure, the utility model provides an automatic proportioning and adding device for coating circulating water agents, including: a reaction barrel 1, a solution tank 7 is fixedly connected to the outer surface of the reaction barrel 1, a metering pump 8 is arranged at the inner bottom of the solution tank 7, a first connecting pipe 9 is arranged at the top of the metering pump 8, the first connecting pipe 9 and the metering pump 8 are communicated, a buoyancy component 6 is arranged inside the reaction barrel 1, and an adjusting component 5 is arranged at the top of the reaction barrel 1; the adjusting component 5, the adjusting component 5 includes a mounting frame 501, the mounting frame 501 is fixedly connected to the top of the reaction barrel 1, an electric telescopic rod 502 is arranged at the top of the mounting frame 501, the telescopic end of the electric telescopic rod 502 slidably penetrates through the top of the mounting frame 501, the telescopic end of the electric telescopic rod 502 is fixedly connected with a connecting plate 504, a pressure sensor 505 is arranged at the bottom of the connecting plate 504, the buoyancy component 6 includes a floating plate 601, the floating plate 601 is arranged inside the reaction barrel 1, a connecting rod 602 is arranged at the top of the floating plate 601, a touch plate 603 is arranged at the top of the connecting rod 602, the touch plate 603 and the pressure sensor 505 are matched, the outer surface of the first connecting pipe 9 fixedly penetrates through the inner top of the solution tank 7, the first connecting pipe 9 is in an inverted L shape, guide rods 503 are symmetrically and fixedly connected to the top of the connecting plate 504, the outer surfaces of the two guide rods 503 slidably penetrate through the inner top of the mounting frame 501, a delivery pump 2 is arranged on the outer surface of one side of the reaction barrel 1, an input pipe 3 is arranged at the input end of the delivery pump 2, the input pipe 3 and the delivery pump 2 are communicated, an output pipe 4 is arranged at the output end of the delivery pump 2, the output pipe 4 and the delivery pump 2 are communicated, and the outer surface of the output pipe 4 fixedly penetrates through the outer surface of the reaction barrel 1 at a position away from the delivery pump 2.

[0025] The effect achieved by the entire embodiment 1 is that during the treatment of coating circulating water, the electric telescopic rod 502 is started, and its telescopic end slides in the inner wall of the mounting frame 501, driving the connecting plate 504 to move downward. The connecting plate 504 slides downward under the limitation of the two guide rods 503, so that the pressure sensor 505 synchronously moves downward to a suitable height. The height where the pressure sensor 505 is located is the height of the capacity of the waste water that can be injected into the reaction barrel 1. The waste water formed by the coating circulating water is stored in an external storage tank and is communicated with the input pipe 3 through a pipe body. The delivery pump 2 is started, and the delivery pump 2 pumps sewage through the input pipe 3 and injects it into the reaction barrel 1 through the output pipe 4. Under the action of buoyancy, the floating plate 601 floats in the reaction barrel 1 in a limited manner, and as the capacity of the injected waste water increases, the touch plate 603 with a larger cross-section arranged above the connecting rod 602 at its top will touch the pressure sensor 505. After the pressure sensor 505 is triggered by the pressure, it sends instructions to the delivery pump 2 and the metering pump 8. The delivery pump 2 stops injecting the waste water, and the metering pump 8 quantitatively extracts the reagent liquid in the solution tank 7 and injects it into the reaction barrel 1 through the first connecting pipe 9 to react with the waste water, realizing the automatic proportioning and adding effect of the coating circulating water agent. There is no need for manual waiting and observation during the water injection process and manual addition of reagents, reducing the manual work intensity.

[0026] Example 2, as Figures 1-5 shown, a second connecting pipe 10 is arranged at the center of the bottom of the reaction barrel 1. The second connecting pipe 10 is communicated with the reaction barrel 1. An electromagnetic valve 11 is arranged on the outer surface of the second connecting pipe 10. The electromagnetic valve 11 is communicated with the second connecting pipe 10. A plurality of fixing rods 604 are arranged at equal intervals at the bottom of the floating plate 601. The fixing rods 604 are matched with the reaction barrel 1.

[0027] The effect achieved by the entire Example 2 is that during discharge, after the sewage reaction treatment, the electromagnetic valve 11 is started to connect the second connecting pipe 10 and the reaction barrel 1. The treated wastewater is discharged through the second connecting pipe 10. When the sewage liquid level in the reaction barrel 1 gradually drops to the bottom of the barrel, by arranging a plurality of fixing rods 604 at equal intervals at the bottom of the floating plate 601, the bottoms of the plurality of fixing rods 604 abut against the bottom of the barrel, playing a supporting role, so that there is a large gap between the floating plate 601 and the inner bottom of the reaction barrel 1, preventing the floating plate 601 from touching the bottom and fitting on the bottom of the barrel, which may cause blockage of the discharge port and affect the normal discharge of sewage, and improving the use effect of the automatic proportioning and adding device for the coating circulating water agent.

[0028] Working principle: When treating the circulating water in the coating process, start the electric telescopic rod 502. Its telescopic end slides inside the inner wall of the mounting frame 501, driving the connecting plate 504 to move downward. The connecting plate 504 slides downward while being limited by two guide rods 503, causing the pressure sensor 505 to move downward synchronously to an appropriate height. The height where the pressure sensor 505 is located is the height of the waste water that can be injected into the reaction barrel 1. The waste water formed by the circulating water in the coating process is stored in an external storage tank and is connected to the input pipe 3 through a pipe body. Start the delivery pump 2. The delivery pump 2 extracts sewage through the input pipe 3 and injects it into the reaction barrel 1 through the output pipe 4. Under the action of buoyancy, the floating plate 601 floats upward within the limit in the reaction barrel 1. As the volume of the injected waste water increases, the touch plate 603 with a larger cross-section above the top connecting rod 602 of the floating plate 601 will touch the pressure sensor 505. After the pressure sensor 505 is triggered by the pressure, it sends instructions to the delivery pump 2 and the metering pump 8. The delivery pump 2 stops injecting waste water, and the metering pump 8 quantitatively extracts the chemical liquid in the solution tank 7 and injects it into the reaction barrel 1 through the first connecting pipe 9 to react with the waste water, achieving the effect of automatic proportioning and adding of the coating circulating water chemicals. There is no need for manual waiting and observation during the water injection process and manual addition of chemicals, reducing the manual labor intensity. During discharge, after the sewage reaction treatment, start the electromagnetic valve 11 to connect the second connecting pipe 10 and the reaction barrel 1. The treated waste water is discharged through the second connecting pipe 10. When the sewage liquid level in the reaction barrel 1 gradually drops to the bottom of the barrel, by equidistantly arranging a plurality of fixing rods 604 at the bottom of the floating plate 601, the bottoms of the plurality of fixing rods 604 abut against the bottom of the barrel, playing a supporting role, so that there is a large gap between the floating plate 601 and the inner bottom of the reaction barrel 1, preventing the floating plate 601 from touching the bottom and fitting against the bottom of the barrel, which may cause blockage of the discharge port and affect the normal discharge of sewage, improving the use effect of the automatic proportioning and adding device for the coating circulating water chemicals.
