[0002] Cement grinding aid is a chemical additive used in the cement production process. Its main function is to enhance the grinding effect of cement and improve the quality of cement. Cement grinding aid is usually a powdery substance. By mixing with cement, it can improve the dispersibility of cement particles, increase its surface area, improve the activity and strength of cement, and reduce the energy consumption of cement. In the process of producing cement grinding aid, different raw materials need to be mixed, so the rotating mixing structure is indispensable.

[0003] The current rotary mixing structure uses the grinding balls inside it to extrude and grind the raw materials during operation, so that different raw materials are mixed more evenly. However, after the work is completed, a large amount of powder will remain on the surface of the grinding balls. If it is not cleaned, it will affect the next use. Currently, the grinding balls are attracted out by magnetic rods. Due to the large number of grinding balls, the work is troublesome and time-consuming.

[0004] In view of the above-mentioned related technologies, a rotary mixing structure for producing cement grinding aids is proposed. Utility Model Content

An embedding groove 74 is provided on the inner wall of the inner cylinder 71, and a through hole is provided inside the embedding groove 74, and a control valve B75 is provided inside the through hole. The raw materials for producing cement grinding aids are loaded into the inner cylinder 71 through the feed pipe 3, and the outer cylinder 1 is rotated by the driving assembly 2, which further drives the inner cylinder 71 to rotate. During the rotation of the inner cylinder 71, the grinding balls continuously squeeze the raw materials to crush and mix the raw materials. After the mixing is completed, the control valves A73 and B75 are opened to make the grinding balls inside the inner cylinder 71 roll out and fall along the through holes.

[0027] An installation groove 78 is provided on the inner wall of the outer cylinder 1, and an electric push rod A781 and an electric push rod B782 are arranged inside the installation groove 78. One group of the electric push rods A781 is installed on the installation groove 78 close to one end of the filter plate 72, and the other group of the electric push rods A781 is installed on the installation groove 78 away from the end of the filter plate 72. The electric push rods A781 and the electric push rods B782 are both movably connected to the inner cylinder 71. After the mixing is completed, the electric push rod A781 contracts and the electric push rod B782 extends, so that the inner cylinder 71 is in a high and low state, wherein the end close to the filter plate 72 is low and vice versa, so as to facilitate the rolling out of the grinding balls.
