[0025] like Figure 1-2As shown, the present application provides a cement grinding aid dosage control device, including a liquid storage tank 1, a partition plate 2 is provided in the liquid storage tank 1, the partition plate 2 divides the interior of the liquid storage tank 1 into a liquid storage chamber 11 and a measuring chamber 12, a liquid inlet pipe 3 is provided in the liquid storage chamber 11, the upper end of the liquid inlet pipe 3 extends to the outside of the liquid storage tank 1, and liquid cement grinding aid can be input into the liquid storage chamber 11 through the liquid inlet pipe 3, a liquid outlet pipe 4 connected to the measuring chamber 12 is provided at the bottom of the liquid storage tank 1, an electromagnetic liquid outlet valve 41 is provided on the liquid outlet pipe 4, and a pumping component 5 is provided on the liquid storage tank 1, and the pumping component 5 is used to pump the liquid cement grinding aid in the liquid storage chamber 11 into the measuring chamber 12, and when the required dosage is reached, the electromagnetic liquid outlet valve 41 is opened to discharge the liquid through the liquid outlet pipe 4. Compared with the prior art, the addition efficiency of the cement grinding aid is greatly improved, the manual labor is reduced, and the possibility of error is effectively reduced.

[0026] like Figure 1-2 As shown, the pumping assembly 5 includes a liquid pump 51, a first pipe 52, and a second pipe 53. The liquid pump 51 is fixedly mounted on the top of the liquid storage tank 1. The first pipe 52 is located in the liquid storage chamber 11. The upper end of the first pipe 52 extends to the outside of the liquid storage tank 1 and is connected to the liquid inlet of the liquid pump 51. The second pipe 53 is located in the measuring chamber 12. The upper end of the second pipe 53 extends to the outside of the liquid storage tank 1 and is connected to the liquid outlet of the liquid pump 51. Specifically, when the liquid pump 51 is started, the liquid cement grinding aid in the liquid storage chamber 11 is transported to the measuring chamber 12 through the cooperation of the first pipe 52 and the second pipe 53.
