DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a calcium carbonate powder mixing and stirring device, comprising a first mixing box 1, a second mixing box 2 is fixedly arranged at the bottom of the first mixing box 1 through a fixed tube 6, a mixing and stirring mechanism is arranged inside the first mixing box 1 and the second mixing box 2 through a dual-axis motor 7, the mixing and stirring mechanism comprises a first stirring paddle 8 and a second stirring paddle 11, a dispersing mechanism is arranged on the top of the inner side of the second mixing box 2, the dispersing mechanism comprises a movable cover 10, the shape of the movable cover 10 is a truncated cone, the movable cover 10 is arranged below the fixed tube 6, rotating plates 9 are symmetrically fixedly arranged on both sides of the bottom end of the first stirring paddle 8, the rotating plates 9 are driven to rotate by the first stirring paddle 8, so that the calcium carbonate powder and additives in the first mixing box 1 can intermittently fall onto the movable cover 10 through the fixed tube 6, so that the calcium carbonate powder and additives can be dispersed through the movable cover 10, and the subsequent mixing and stirring is convenient.

[0022] In this embodiment, a slide bar 14 is installed in an internal limiting sliding manner at the top of the movable cover 10, and the cross-sectional shape of the slide bar 14 is "T"-shaped. A spring is fixedly installed between the bottom end of the slide bar 14 and the movable cover 10, and the spring is sleeved on the slide bar 14. The outer wall of the movable cover 10 is fixedly provided with protrusions 13 in an array. The movable cover 10 is slidably installed on the top of the second stirring paddle 11. The movable cover 10 can slide downward on the slide bar 14 under the action of gravity of the calcium carbonate powder and the additive, and compress the spring downward, and can also move upward after the amount of calcium carbonate powder and the additive on the movable cover 10 is reduced, so as to facilitate the dispersion of the calcium carbonate powder and the additive.

[0023] In this embodiment, the dual-axis motor 7 is fixedly installed between the first mixing box 1 and the second mixing box 2, the first stirring paddle 8 is fixedly installed on the output shaft at the top of the dual-axis motor 7, the first stirring paddle 8 is arranged inside the first mixing box 1, the second stirring paddle 11 is fixedly arranged on the output shaft at the bottom of the dual-axis motor 7, the second stirring paddle 11 is movably arranged inside the second mixing box 2, the rotating plate 9 is arranged on the top of the fixed tube 6, the top of the first mixing box 1 is symmetrically provided with feeding ports 4 on both sides, the bottom end of the second stirring paddle 11 is fixedly provided with a cleaning plate 12 corresponding to the bottom of the inner side of the second mixing box 2, a discharge port 5 is provided at the center position of the bottom of the second mixing box 2, a valve is provided on the discharge port 5, and legs 3 are fixedly provided on the four sides of the bottom of the second mixing box 2, the dual-axis motor 7 drives the first stirring paddle 8 and the second stirring paddle 11 to rotate, which can respectively perform preliminary stirring and secondary stirring on the calcium carbonate powder and the additive, and can improve the mixing efficiency of the calcium carbonate powder and the additive.

[0024] When the calcium carbonate powder mixing and stirring device is used, the double-shaft motor 7 is started, and the two output shafts of the double-shaft motor 7 drive the first stirring paddle 8 and the rotating plate 9 to rotate inside the first mixing box 1, and drive the second stirring paddle 11 and the cleaning plate 12 to rotate inside the second mixing box 2, and calcium carbonate powder and additives are added to the first mixing box 1 through the feeding port 4. The calcium carbonate powder and additives are preliminarily mixed under the stirring of the first stirring paddle 8. At the same time, when the rotating plate 9 is removed from the top of the fixed tube 6, the calcium carbonate powder and additives fall through the fixed tube 6 onto the surface of the movable cover 10. At the same time, the movable cover 10 slides downward on the slide bar 14 under the gravity of the calcium carbonate powder and additives and compresses the spring, and part of the calcium carbonate powder and additives slide off the surface of the movable cover 10. When the rotating plate 9 moves to the top of the fixed tube 6, the second stirring paddle 11 and the cleaning plate 12 are driven by the second stirring paddle 11 and the cleaning plate 12. The calcium carbonate powder and additives in a mixing box 1 cannot fall down. As the amount of calcium carbonate powder and additives on the surface of the movable cover 10 decreases, the movable cover 10 will slide upward on the slide bar 14 under the elastic force of the spring. As the rotating plate 9 rotates axially, the movable cover 10 can swing back and forth up and down under the action of the calcium carbonate powder and additives, which is convenient for dispersing the calcium carbonate powder and additives through the movable cover 10 and the protrusion 13. The second stirring paddle 11 performs secondary mixing and stirring on the calcium carbonate powder and additives, which can improve the mixing efficiency of the calcium carbonate and additives, ensure the uniformity of the mixing, and is highly practical. When discharging, the valve on the discharge port 5 is opened, and the second stirring paddle 11 drives the cleaning plate 12 to rotate inside the second mixing box 2, and the calcium carbonate powder and additives inside the second mixing box 2 are discharged through the cleaning plate 12.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
