[0049] In Example 4, the first liquid level sensor, the second liquid level sensor, and the third liquid level sensor are arranged from high to low in the stirring tank. The first liquid level sensor corresponds to the clean water branch to stop adding clean water, the second liquid level sensor corresponds to the working liquid level of the agitator in the stirring tank, and the third liquid level sensor corresponds to the working liquid level of the transmission pump to stop working. In this embodiment, bleaching powder is added to the stirring tank through the vacuum feeding pump, and clean water is added to the stirring tank through the clean water branch at the same time; when the liquid level in the stirring tank reaches the second liquid level sensor, the agitator starts to work; when the liquid level in the stirring tank reaches the first liquid level sensor, the clean water branch cuts off the connection with the stirring tank; stirring continues, and when stirring reaches the preset state, the stirring solution is transported to the clarified liquid storage tank through the delivery pump, and when the liquid level drops to the third liquid level sensor, the transmission pump stops working. In the embodiment in the figure, the first, second, and third liquid levels correspond to 0.4m, 0.8m, and 1.7m, respectively. The fourth liquid level sensor and the fifth liquid level sensor are arranged from high to low in the clarified liquid storage tank. The fourth liquid level sensor corresponds to the liquid level at which the bleaching powder solution is stopped from being delivered to the clarified liquid storage tank, and the fifth liquid level sensor corresponds to the connection between the clarified liquid storage tank and the bleaching powder dosing pump. In this embodiment, when the liquid level in the clarified liquid storage tank drops to 0.2m, the bleaching powder dosing pump is stopped. If the liquid level in the storage tank reaches 1.8m, the transfer pump is stopped. The control management system controls the start and shut down of each component through each liquid level.

[0050] In Examples 1-4, the storage capacity of a single clarified liquid storage tank and the number of clarified liquid storage tanks are set according to the time and amount of each dispensing set in the stirring tank; ensuring that the bleaching powder solution in the clarified liquid storage tank is continuously discharged during the dispensing period of the stirring tank. In the example in the figure, two clarified liquid storage tanks are set to store 6m 3 For the reagent, one bleaching powder dosing pump is used and the other is kept in reserve. Under normal operation, the inlet valve of one bleaching powder dosing pump is always open, and the inlet valve of the other bleaching powder dosing pump is always closed. During the reagent configuration, the reagents in the two bleaching powder clarified liquid storage tanks can ensure that the dosing pumps can work continuously for 6 hours, ensuring sufficient time for dispensing. The single dispensing time for two clarified liquid storage tanks is less than 6 hours. The reagent configuration frequency is once a day or twice a day, and the dispensing and dosing do not affect each other, so it can meet the nighttime dosing needs of the water plant.

[0051] In embodiments 1-4, in order to prevent the device from being affected by weather factors and extend its service life, a rainproof canopy is also included, and the rainproof canopy cover is arranged directly above the entire device.

[0052] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of patent application of the present invention still fall within the protection scope of the present invention.
