The outer wall of the preparation layer 21 is provided with a grinding aid inlet 201, and the outer wall of the dilution layer 22 is provided with a clean water inlet 202. The clean water inlet 202 penetrates the outer shell of the dilution layer 22 and the partition 23, and the grinding aid inlet 201 penetrates the outer shell of the preparation layer 21, which solves the problem that the traditional dilution device cannot automatically stir the grinding aid and evenly spray it in the cement.

As shown in Figure 1, the outer wall of the cement box 1 is provided with a cement inlet 11 and a controller 12, and the bottom of the cement box 1 is provided with a cement outlet 14. The cement inlet 11 and the cement outlet 14 both pass through the outer shell of the cement box 1. Cement is added to the cement box 1 through the cement inlet 11, and the cement in the cement box 1 is discharged through the cement outlet 14. The controller 12 is connected to the cement inlet 11 and the clean water inlet 202 through a cable. The cement inlet 11 and the clean water inlet 202 are provided with flow detectors. The cement inlet 11 and the clean water inlet 202 transmit the recorded data to the controller 12 through the cable. The controller 12 can detect the content of added cement and the content of grinding aid.

As shown in FIG. 3 , the nozzle 44 is an internally penetrating pipe, and the nozzle 44 communicates with the shaft channel 46 and the interior of the cement box 1 .

As shown in FIGS. 1-3 , a rotating shaft base 13 is provided at the bottom center of the cement box 1 , and the bottom of the rotating shaft 41 is stuck in the rotating shaft base 13 , and the rotating shaft base 13 plays a role in fixing the rotating shaft 41 .

As shown in FIG4 , the grinding aid stirring rod 42 is welded on the preparatory layer 21. Driven by the rotating shaft 41, the grinding aid stirring rod 42 continuously stirs the grinding aid slurry in the preparatory layer 21. An opening (231) is provided on the partition 23. The preparatory layer 21 is connected to the clean water inlet 202 and the dilution layer 22 through the opening (231) on the partition 23. After the clean water inlet 202 is opened, water flows into the dilution layer 22 through the clean water inlet 202, and the grinding aid in the preparatory layer 21 also enters the dilution layer 22 through the clean water inlet 202 to be diluted with clean water.

As shown in FIG5 , the bottom of the dilution layer 22 is low near the center, and the bottom of the dilution layer 22 is high on the outside away from the center. The shaft opening 43 is located at the lowest point in the center of the bottom of the dilution layer 22 , and the grinding aid dilution liquid enters the shaft channel 46 through the shaft opening 43 .

As shown in FIG. 6 , a cement stirring rod 45 is disposed on the rotating shaft 41 . The cement stirring rod 45 is located inside the cement box 1 . The cement stirring rod 45 stirs the cement inside the cement box 1 when driven by the motor 4 .

The motor 4 is a fixed motor connected to an external 220V power supply.

Working principle: the grinding aid slurry diluted once is added through the grinding aid inlet 201. The current grinding aid slurry is not stirred evenly and needs to be further diluted. After the slurry falls into the preparatory layer 21, the motor 4 is turned on to drive the rotating shaft 41 to rotate, and cement is added through the cement inlet 11. The grinding aid stirring rod 42 is driven by the rotating shaft 41 to stir the slurry, so that the grinding aid in the slurry is gradually uniform. When all the cement is added, the clean water inlet 202 is opened to add clean water to the dilution layer 22. At the same time, the slurry stirred evenly in the preparatory layer 21 is also flushed into the dilution layer 22 by clean water through the clean water inlet 202 for dilution. The evenly stirred slurry is more easily diluted by clean water. After that, the diluted grinding aid flows into the rotating shaft channel 46 through the rotating shaft opening 43, and is evenly sprayed on the cement in the cement box 1 while rotating through the nozzle 44. It is continuously stirred evenly by the cement stirring rod 45, and finally the processed cement is discharged through the cement outlet 14.

In summary, the cement grinding aid liquid dilution device realizes stirring of the grinding aid slurry while stirring the cement through the grinding aid stirring rod 42 on the rotating shaft 41, and after the slurry is stirred evenly, it is convenient to dilute the grinding aid with clean water;

The diluted grinding aid is introduced into the shaft channel 46 through the shaft opening 43, and then the diluted grinding aid liquid is evenly sprayed on the cement through the nozzle 44 by centrifugal force, which effectively avoids most of the grinding aid from accumulating in the same position of the cement and achieves the purpose of evenly distributing the grinding aid in the cement.
