In addition, it should be noted that the pipe body connected to the inlet and outlet of the metering pump 7 and the pipe body connected to the inlet and outlet of the rehydration pump 5 are both made of acid and alkali resistant hoses to extend the service life of this equipment.

[0026] When the fluoride ion detector 2 and the chloride ion detector 3 detect that the fluoride ions and chloride ions in the waste liquid in the reaction barrel 1 exceed the standard, first add an appropriate amount of water to the storage barrel 4, and then pump the concentrated drug solution in the drug barrel 6 into the storage barrel 4 through the rehydration pump 5 to mix the drug and water to form a drug solution. After that, use the metering pump 7 to pump the drug solution in the storage barrel 4 into the reaction barrel 1, so that the drug solution and the waste liquid are fully mixed and reacted to remove the chloride ions and chloride ions in the waste liquid; when the fluoride ion detector 2 and the chloride ion detector 3 detect that the fluoride ions and chloride ions in the waste liquid are lower than the threshold value, the waste liquid can be discharged, achieving the effect of automatic dosing, and having the characteristics of accurate drug dosage addition. In addition, the automatic dosing structure of the present application is simple, easy to operate, and practical.

The water in the storage tank 4 and the chemical solution are fully mixed, thereby improving the uniformity of the chemical solution.

[0028] In one or more embodiments, the storage barrel 4 is disposed in the liquid storage tank 9 .

[0029] See also Figure 2 The storage barrel 4 is arranged on the frame, and a liquid storage box 9 with an open top is arranged on the frame. The storage barrel 4 is arranged in the liquid storage box 9; through this arrangement, the problem of excessive water or medicine in the storage barrel 4 overflowing from the storage barrel 4 and causing pollution can be avoided, thereby improving the safety of the use of this equipment.

[0030] In one or more embodiments, an ultrasonic level meter 10 is disposed above the interior of the reaction barrel 1 and / or the storage barrel 4 .

The one-way valve can also be used to allow only the liquid medicine to enter the reaction barrel 1, while preventing the wastewater in the reaction barrel 1 from entering the storage barrel 4 and contaminating the medicine.

[0035] In one or more embodiments, the outlet of the metering pump 7 is connected to the reaction barrel 1 through a diaphragm pump. Figure 1 、 Figure 2 It should be noted that the metering pump 7 can accurately control the flow rate of the liquid medicine, and the diaphragm pump can ensure that the liquid medicine does not leak during transportation.
