[0002] Most of the water used in human society is treated by water purification plants. The water purification and disinfection treatment carried out by water purification plants is to ensure the safety of biological water. At present, the chlorine disinfection process is mostly used for filtered water in China. During chlorination disinfection, the amount of chlorine added should generally meet the chlorine requirement for eliminating bacteria to achieve the specified disinfection standard index and the residual chlorine required to inhibit the re-reproduction of residual bacteria.

However, the proportion of manual addition cannot accurately control the amount of chlorine added, resulting in excessive or insufficient chlorine addition, affecting the treatment effect of the treated water. In order to facilitate the addition of a fixed amount of chlorine to the treatment pool for the treated water, we provide a chlorination control device for the post-filter process.

[0024] During use, a chlorine source is fed into the mixing barrel 1 from the feed port 7, water enters the mixing barrel 1 from the water inlet pipe 6, the motor 9 is started, driving the active rotating shaft 24 to rotate, and the active rotating shaft 24 drives the stirring paddle 23 to stir the water and chlorine source to form a chlorine-containing mixed liquid.
[0025] The dosing assembly includes a U-shaped push-pull column 14, an electric push rod 15, two sets of fixed rings 17, a fixed rod 20 and an insulating jacket 21. The third fixed plate 13 is fixedly connected between the quantitative cylinder 12 and the first fixed plate 4. The bottom of the quantitative cylinder 12 is fixedly connected to a liquid outlet pipe 19, and a second one-way valve 26 is installed on the liquid outlet pipe 19. One end of the U-shaped push-pull column 14 is fixedly connected to a rubber piston 25, and the rubber piston 25 is slidably connected to the inner wall of the quantitative cylinder 12.

[0026] When a chlorine-containing mixed liquid needs to be quantitatively added, the electric push rod 15 is started, and the U-shaped push-pull column 14 is pulled up by the electric push rod 15. The U-shaped push-pull column 14 drives the rubber piston 25 to move upward. Due to the action of the second one-way valve 26, the chlorine-containing mixed liquid passes through the delivery pipe 10 under the action of air pressure, passes through the first one-way valve 11 and is sucked into the quantitative cylinder 12.

The motor 9 is started, driving the active rotating shaft 24 to rotate, and the active rotating shaft 24 drives the stirring paddle 23 to stir the water and the chlorine source to form a chlorine-containing mixed liquid. When the chlorine-containing mixed liquid needs to be added quantitatively, the electric push rod 15 is started, and the U-shaped push-pull column 14 is pulled up by the electric push rod 15. The U-shaped push-pull column 14 drives the rubber piston 25 to move upward. Due to the action of the second one-way valve 26, the chlorine-containing mixed liquid passes through the delivery pipe 10 under the action of air pressure, passes through the first one-way valve 11 and is sucked into the quantitative cylinder 12. One end of the U-shaped push-pull column 14 is fixedly connected to the fixed ring 17, and the fixed ring The contact position between the conductive clip 22 on the ring 17 and the resistance wire 18 changes, and the resistance sensor detects the change in resistance of the resistance wire 18. The resistance sensor transmits the generated data to the controller 3. The controller 3 collects and analyzes the resistance change to obtain the current amount of chlorine-containing mixed liquid suction. When the set amount of chlorine-containing mixed liquid suction is reached, the electric push rod 15 is started and stopped, so that a certain amount of chlorine-containing mixed liquid is sucked into the metering cylinder 12. After that, the electric push rod 15 pushes down the U-shaped push-pull column 14 to move downward. Under the unidirectional flow action of the first one-way valve 11, a certain amount of chlorine-containing mixed liquid will be transported into the water to be treated through the liquid outlet pipe 19 and the second one-way valve 26.
