A sampling pipeline 16 is fixedly connected to the right side of the pressure gauge 14 and is fixedly connected to the fourth pipeline 8. A back pressure valve 15 is fixedly connected to the right side of the sampling pipeline 16 and is fixedly connected to the fourth pipeline 8. Protective sleeves 24 are fixedly connected to the surfaces of the first pipeline 5, the second pipeline 6, and the third pipeline 7. A light strip 17 is fixedly connected to the surface of the vertical plate 4.
[0026] In this embodiment, the first pipe 5, the second pipe 6, the third pipe 7, and the fourth pipe 8 are all interconnected, which can enhance the overall continuity of the equipment.
[0027] In this embodiment, the first pipe 5, the second pipe 6, and the third pipe 7 are all L-shaped structures. The bends of the first pipe 5, the second pipe 6, and the third pipe 7 are all provided with protective sleeves 24. By providing protective sleeves 24, the bends of multiple sets of pipes can be protected.
[0028] In this embodiment, the vertical plate 4 is vertically set on the top of the base 1. The first pipe 5, the second pipe 6, the third pipe 7 and the fourth pipe 8, as well as the components on their surfaces, can be fixedly connected to the vertical plate 4. By setting the vertical plate 4, each group of pipes and other components can be installed on the vertical plate 4 to provide support.
[0029] In this embodiment, the light strip 17 is arranged in an "L" shape on the surface of the vertical plate 4. By setting the light strip 17, maintenance personnel can be assisted in seeing the instrument clearly in dim light.
[0030] Example 2
[0031] Based on Example 1, a preferred embodiment of the quantitative chlorination device provided by this utility model is as follows: Figures 1 to 4As shown: An LED control board 19 is fixedly connected to the top of the base 1. Side plates 20 are fixedly connected to both sides of the LED control board 19. A connecting rod 21 is rotatably connected inside the side plate 20. A flip cover 22 is fixedly connected to the tail of the connecting rod 21. A torsion spring 23, which is fixedly connected to the side plate 20, is fixedly connected to the side of the flip cover 22.
[0032] In this embodiment, when the flip cover 22 is closed, it can completely cover the LED control board 19. By setting the flip cover 22, when the flip cover 22 is closed, it can be tightly attached to the LED control board 19 under the elastic force of the torsion spring 23, thereby protecting the surface of the LED control board 19.
[0033] In this embodiment, the torsion spring 23 is perpendicular to the side plate 20. The flip cover 22 is tightly fitted to the LED control board 19 under the action of the torsion spring 23. The torsion spring 23 can fix the flip cover 22 when it is closed under its own elastic force.
[0034] The working principle and usage process of this utility model are as follows: First, to better control the dosage of the mechanical diaphragm metering pump 18, a variable frequency control device is added during the modification process. Considering the significant difference in influent volume between summer and winter, the manual stroke control is fixed at either 50% or 100% during dosing. The frequency converter precisely controls the sodium hypochlorite dosage. On-duty personnel can intuitively observe and adjust the dosage through the frequency or percentage display on the LED control board 19 of the frequency converter. The influent volume and frequency conversion signal are transmitted to the control room, where the PLC controlling the filter is extended to achieve proportional control based on the influent volume. This realizes the automation and precision of sodium hypochlorite dosage, effectively improving the disinfectant dosing effect of the water plant, effectively saving sodium hypochlorite usage, and ensuring the residual chlorine level of the effluent. It also reasonably reduces the workload of on-duty personnel.
[0035] By setting up the light strip 17, maintenance personnel can see the instrument clearly in dim light. By setting up the protective cover 24, the curved parts of multiple sets of pipelines can be protected. By setting up the flip cover 22, when the flip cover 22 is closed, it can be tightly attached to the LED control board 19 under the elastic force of the torsion spring 23, thereby protecting the surface of the LED control board 19. A cylindrical solution tank 2 is used, and a liquid level gauge is installed at the outlet. Since the cross-sectional area on the horizontal plane is the same, the scale drop is proportional to the volume, which effectively measures the volume of sodium hypochlorite used in a single shift.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
