Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model comprises a dosing barrel 1, a logic controller 11, a contactor 10 and a dosing metering pump 8; the liquid outlet of the dosing barrel 1 is connected with the liquid inlet of a dosing metering pump 8, a pump inlet valve 7 is arranged on a connecting pipeline, and the liquid outlet of the dosing metering pump 8 is connected with a dosing port on a circulating water pipeline 12; a pH access port and a conductivity interface are arranged on the circulating water pipeline 12, and a pH value detector and a conductivity detector are respectively arranged on the circulating water pipeline; the contactor 10, the pH value detector and the conductivity detector are respectively and electrically connected with the logic controller 11; the contactor 10 is connected with a dosing metering pump 8. The high liquid level set point and the low liquid level set point of the dosing barrel 1 are respectively connected with the liquid level sensor 6 through an upper pipeline and a lower pipeline, and isolation valves 5 are respectively arranged on the upper pipeline and the lower pipeline. The medicine adding barrel 1 is internally provided with a stirrer which is electrically connected with the logic controller 11. The agitator includes puddler 2, is equipped with stirring vane 3 on the puddler 2. The upper end and the lower end of the medicine adding barrel 1 are respectively provided with a bearing, the upper end and the lower end of the stirring rod 2 are respectively connected with the inner wheels of the upper bearing and the lower bearing, and the outer wheel of the bearing is fixedly connected with the medicine adding barrel 1. A check valve 9 is arranged between the liquid outlet of the dosing metering pump 8 and the dosing port on the circulating water pipeline 12.

Logic controller 11 may employ CX-3. The liquid level sensor 6 outputs 4-20 milliamperes, and the numerical value of the high and low dropping sites can be freely set.

The utility model discloses a concrete implementation method: the pH value detector and the conductivity detector detect the water quality of the circulating water in the circulating water pipeline 12, and the logic controller 11 judges the dosage according to the water quality parameters. When adding medicine, the logic controller 11 triggers the contactor 10 to close through the control loop, and keeps the pump inlet valve 7 and the check valve 9 of the medicine adding metering pump 8 in a normally opened state, so that the medicine adding metering pump 8 operates and inputs the liquid in the medicine adding barrel 1 into the circulating water pipeline 12. After the water quality meets the requirement, the logic controller 11 triggers the contactor 10 to be disconnected through the control loop, and the dosing metering pump 8 stops running, so that the water quality is monitored in real time and the dosing is automatically carried out.

After the liquid level in the dosing barrel 1 reaches the low liquid level set point or the high liquid level set point, the liquid level sensor 6 sends the liquid level information to the logic controller 11, and an alarm can be given through the logic controller 11.
