[0028] In some technical schemes, referring to Figure 1 , the storage box 8 is connected with the distribution pipe 12 at one side of the lower end, and the control valve 13 is arranged at the upper end of the distribution pipe 12.

[0029] In this technical scheme, when the chemical reagent in the storage box 8 is at the same level as the liquid level meter 11, the control valve 13 at the upper end of the distribution pipe 12 is opened, the chemical reagent in the storage box 8 is conveyed into the rotating installation structure through the distribution pipe 12, and the purpose of dividing and conveying the chemical reagent is achieved.

[0035] Working principle:

[0036] When quantitatively dispensing chemical reagents, staff place storage containers 17 of specified sizes on several racks 16 according to dispensing requirements. After placement, a stepper motor 14 drives the mounting plate 15 to rotate, positioning the storage containers 17 sequentially below the dispensing pipe 12. Staff then inject the prepared chemical reagents into the storage box 2. Following quantitative dispensing requirements, the electric push rod 9 on the upper end of the mounting rack 5 is activated, changing the position of the sealing plate 10 within the storage box 8 and altering its volume. This change can be observed through the scale plate 19 on the upper end of the observation window 18. The position of the sealing plate 10 is precisely adjusted. After the adjustment is completed, the conveying pump 3 in the storage tank 2 is driven to work. The chemical reagent in the storage tank 2 is conveyed to the one-way valve 6 and the connecting hose 7 through the conveying pipe 4, and finally enters the storage tank 8. When the liquid level of the chemical reagent in the storage tank 8 is at the same level as the liquid level gauge 11, the liquid level gauge 11 issues an alarm signal. The control system cuts off the power to the conveying pump 3. The one-way valve 6 prevents the backflow of the chemical reagent in the storage tank 8. The control valve 13 located at the upper end of the dispensing pipe 12 is opened. The chemical reagent in the storage tank 8 is conveyed to the rotating installation structure through the dispensing pipe 12, so as to achieve the purpose of dispensing and conveying the chemical reagent.
