Calcium carbonate is also an important building material and has a wide range of uses in industry. A mixing tank is required for the production of calcium carbonate, and a mixing tank is used to homogenize the calcium carbonate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 - Figure 4 The utility model provides a powder stirring and homogenizing device, including a cylinder 1, a feed pipe 6 is fixedly connected to the bottom end of the outer side of the cylinder 1, and a corresponding sealing plug is clamped at the inlet end of the feed pipe 6; a fixed seat 2 is fixedly connected to the middle part of the inner side of the cylinder 1, and a stirring mechanism 3 is arranged at the bottom of the fixed seat 2, and the stirring mechanism 3 includes a central axis 32, the central axis 32 passes through the fixed seat 2 and extends to the top of the fixed seat 2, the central axis 32 is slidably connected to the fixed seat 2, a rotating frame 31 is fixedly connected to the middle part of the central axis 32, a plurality of rotating shafts 34 are rotatably connected to the outer edge of the bottom of the rotating frame 31, and the plurality of rotating shafts 34 are distributed around the rotating frame 31 at equal angles, and a plurality of stirring blades equidistantly distributed along the vertical direction are fixedly connected to the bottom end of the central axis 32 Wheel one 33, the bottom ends of several rotating shafts 34 are fixedly connected with several stirring impellers 2 35 equidistantly distributed along the vertical direction, and several stirring impellers 2 35 are staggered with stirring impeller one 33. The top end of the inner side of the cylinder 1 is provided with a driving mechanism 4 for driving the central axis 32 to rotate, and the middle part of the inner side of the cylinder 1 is provided with a transmission member 36 for driving all the rotating shafts 34 to rotate. The transmission member 36 includes an inner gear ring 361, and the inner gear ring 361 is fixedly connected to the inner side of the cylinder 1. The top ends of several rotating shafts 34 are fixedly connected with gears 362, and several gears 362 are meshed with the inner gear ring 361. The vertical length of the inner gear ring 361 is greater than the vertical length of the gear 362, and several gears 362 can slide vertically along the tooth groove of the inner gear ring 361.

[0027] The central shaft 32 can be driven to rotate by the driving mechanism 4, which makes the rotating frame 31 rotate synchronously, and all the rotating shafts 34 rotate circumferentially around the central shaft 32, so that the rotating shaft 34 can stir the outer edge of the inner side of the cylinder 1 circumferentially, and at the same time, the central shaft 32 drives all the stirring impellers 1 33 to rotate to stir the central area inside the cylinder 1. When the rotating shaft 34 rotates circumferentially, it will drive the corresponding gear 362 to roll along the inner gear ring 361, which makes all the rotating shafts 34 rotate, and all the stirring impellers 2 35 rotate. Since the stirring impellers 2 35 and the stirring impellers 1 33 are staggered, the stirring impellers 2 35 and the stirring impellers 1 33 can stir the central area inside the cylinder 1 with a higher density, thereby greatly improving the overall homogenization effect.

[0028] Reference Figure 5 The driving mechanism 4 includes a mounting plate 41, which is fixedly connected to the top of the inner side of the cylinder 1. A retractable connecting shaft 42 is rotatably connected to the mounting plate 41. The bottom end of the connecting shaft 42 is fixedly connected to the top of the central shaft 32. A motor 43 is fixedly installed on the top of the cylinder 1. The output shaft of the motor 43 is fixedly connected to the top of the connecting shaft 42. The connecting shaft 42 can be rotated by starting the motor 43, which drives the central shaft 32 to rotate, so that all the stirring impellers 33 rotate to stir the central area inside the cylinder 1.

[0029] Reference Figure 6 The connecting shaft 42 includes a sleeve shaft 421, the top of which is fixedly connected to the output shaft of the motor 43, the bottom of which is slidably connected to a plug shaft 422, the bottom of which is fixedly connected to the central shaft 32, the outer side of which is fixedly connected to a limit bar 423, the limit bar 423 is slidably connected to the inner wall of the sleeve shaft 421, the inner wall of the sleeve shaft 421 is provided with a limit groove 424 matching the limit bar 423, and the limit bar 423 can slide along the limit groove 424. The limit bar 423 can limit the relative rotation of the plug shaft 422 and the sleeve shaft 421, so that the plug shaft 422 always keeps synchronous rotation with the sleeve shaft 421 when sliding vertically.

[0030] Reference Figure 7 A lifting mechanism 5 is provided at the top of the fixed seat 2, and the lifting mechanism 5 includes a rotating plate 51, which is fixedly connected to the top of the central shaft 32, and a protrusion 52 is fixedly connected to one end of the bottom of the rotating plate 51. A top block 53 is fixedly connected to the top of the fixed seat 2, and the top block 53 is intermittently in contact with the protrusion 52. The top block 53 and the protrusion 52 have the same diameter, and the top surface of the top block 53 and the bottom surface of the protrusion 52 are both arc structures. A spring 54 is sleeved on the top of the central shaft 32, and the bottom end of the spring 54 is in contact with the top wall of the fixed seat 2.

[0031] The working principle of the utility model is as follows: first, the material is introduced into the cylinder 1 through the feed pipe 6, and then the motor 43 is started to rotate the connecting shaft 42, which makes the connecting shaft 42 drive the central shaft 32 to rotate, so that all the stirring impellers 1 33 rotate to stir the central area inside the cylinder 1, and the central shaft 32 can drive the rotating frame 31 to rotate synchronously, so that all the rotating shafts 34 rotate circumferentially around the central shaft 32, so that the rotating shaft 34 can stir the outer edge of the inner side of the cylinder 1 circumferentially, and the rotating shaft 34 will drive the corresponding gear 362 to roll along the inner gear ring 361 when the rotating shaft 34 rotates circumferentially, so that all the rotating shafts 34 rotate, and all the stirring impellers 2 35 rotate. Since the stirring impellers 2 35 and the stirring impellers 1 33 are staggered, the stirring impellers 2 35 and the stirring impellers 1 33 can stir the central area inside the cylinder 1 with a higher density;

[0032] When the central shaft 32 rotates, it will drive the rotating plate 51 to rotate, and the protrusion 52 will rotate synchronously with the rotating plate 51. When the protrusion 52 contacts the top block 53, the protrusion 52 will be affected by the top block 53 to move the rotating plate 51 upward, which makes the central shaft 32 translate upward. When the protrusion 52 is separated from the top block 53, the rotating plate 51 moves downward under the action of gravity and contacts with the spring 54, and the spring 54 can reduce the downward impact force of the rotating plate 51. In this cycle, the rotating plate 51 will reciprocate up and down in the vertical direction, which makes the central shaft 32 reciprocate up and down, and the rotating frame 31 drives all the rotating shafts 34 to reciprocate up and down, so that all the stirring impellers 2 35 and the stirring impellers 1 33 can stir different areas in the vertical direction, thereby greatly improving the overall homogenization effect.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
