Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

In order to overcome the deficiencies of the prior art, the utility model provides a sodium hypochlorite dosing device here, which is suitable for the preparation and dosing of disinfectant solutions in water treatment such as water supply and waste water, and has the advantages of accurate configuration concentration, high dosing It has the characteristics of accurate measurement, convenient and simple operation, high degree of automation, reduction of staff, efficiency and energy saving. As shown in Figures 1-4: the dosing device includes a solution box 1 for dissolving and storing powders and solutions. The device includes a liquid medicament dosing device for dosing the uniform solution in the solution tank 1 , and the liquid medicament dosing device is composed of two electromagnetic metering pumps 9 with frequency conversion function and corresponding infusion pipelines 10 . The device also includes a useful control box 2, the function of which is to control and monitor the whole set of dosing device. Wherein the solution box 1 , the liquid medicine dosing device and the control box 2 are all located on the base 14 .

As shown in FIG. 3 : a liquid level gauge 3 for monitoring the liquid level of the solution tank 1 is included on the outside of the solution tank 1 .

In addition, an overflow port 4 and an emptying port 5 are also provided on the solution tank 1 . A water inlet pipe 6 is installed on the outer upper end of the solution tank 1, and a water inlet valve 7 is installed on the water inlet pipe 6 at the same time. The liquid outlet 8 of the solution tank is arranged at the lower end position of the solution tank 1, and the infusion pipeline 10 is directly connected with the solution tank fluid outlet 8, wherein the corresponding infusion pipeline 10 is also correspondingly provided with an infusion fluid outlet control valve 11 .

This device is used for the dissolving configuration and dosing of sodium hypochlorite, and the sodium hypochlorite solution is used for disinfection in the water treatment process.

Solution preparation: pour the sodium hypochlorite medicine (solid powder) that has been weighed and quantified (according to the design amount) into the solution tank, open the water inlet valve 7 of the dissolution tank, and when the liquid level reaches a high level (can be done by a liquid level gauge) Automatically close the water inlet valve 7 to stop water intake.

Solution dosing:

Open the corresponding infusion liquid outlet control valve 14, start the electromagnetic metering pump (here there are two sets, one for use and one for standby), and automatically adjust the dosage of the electromagnetic metering pump 9 (with frequency converter) according to the water flow and residual chlorine. When the solution tank 1 reaches a low liquid level, the electromagnetic metering pump 9 is automatically stopped and the alarm is realized through the control box 2, and the above solution preparation is continued. Among them, the solution tank liquid level gauge (low liquid level) and two electromagnetic metering pumps 9 realize system interlocking.

specific dispensing solution

1) Press the "Run" button;

2) Open the water inlet valve 7 and inject clean water into the solution tank 1;

3) Manually pour the weighed sodium hypochlorite dry powder (10kg/d) into the solution tank 1;

4) When the liquid level reaches the high liquid level, the water inlet valve 7 is automatically closed;

Specific liquid dosing

1) Open the outlet valve 14 of the solution tank;

2) Check the state of the inlet and outlet valves of the electromagnetic metering pump 9 (1 for use and 1 for standby) to be activated to make it open; start the electromagnetic metering pump 9 to add medicine to the dosing point;

3) When the liquid level Li-2 in the solution tank drops to a low level, the pump will be automatically stopped and an alarm will be issued; at the same time, the solution tank will start to perform the "medicine solution preparation" operation.

Dosing amount control: The device uses an electromagnetic metering pump 9 to add chemicals. The electromagnetic metering pump 9 is equipped with manual stroke adjustment and frequency conversion adjustment, which can accurately control the amount of dosing manually and automatically.

The frequency converter adjusts the frequency through the raw water inlet flow meter Fi-1 and the raw water residual chlorine Cl-1 signal, thereby controlling the dosing amount of the metering pump. (1) When the raw water inlet flow Fi-1/2 increases, the dosing volume of the corresponding dosing pump increases; otherwise, it decreases (the setting value is adjustable and determined during commissioning). (2) When the residual chlorine in the effluent continues to increase, the dosing amount of the corresponding dosing pump will gradually decrease to the appropriate amount of residual chlorine (the maximum value should be set during debugging, and the dosing amount must not exceed the safe value). When the residual chlorine in the effluent continues to decrease, the dosing amount of the corresponding dosing pump will gradually increase to the appropriate amount of residual chlorine.
