DETAILED DESCRIPTION

[0014] like Figure 1-3 As shown: a vertical convection mixer comprises a mixing barrel 1, and three evenly distributed legs 12 are fixedly connected to the bottom of the mixing barrel 1; a rotating shaft 2 is rotatably connected between the center of the inner top wall and the inner bottom wall of the mixing barrel 1, and the upper and lower ends of the rotating shaft 2 are respectively rotatably connected to the center of the inner top wall and the inner bottom wall of the mixing barrel 1, and the bottom outer wall and the top outer wall of the rotating shaft 2 are respectively fixedly sleeved with a lower stirring impeller 3 and an upper stirring impeller 4, and the lower stirring impeller 3 and the upper stirring impeller 4 are mirror-symmetrical up and down, and the lower stirring impeller 3 and the upper stirring impeller 4 have the same shape and size, and the blades of the lower stirring impeller 3 and the upper stirring impeller 4 are arc-shaped, and two middle stirring blades 5 are fixedly connected to the upper and lower positions of the outer wall of the rotating shaft 2, and the rotating shaft 2 is fixedly connected to the middle of the outer wall of two connecting rods 6, a scraper 7 is fixedly connected between the outer ends of the two connecting rods 6, the ends of the two connecting rods 6 are fixedly connected to the scraper 7, the scraper 7 is clearance-matched with the inner wall of the mixing barrel 1, a motor 8 is fixedly connected to the top center of the mixing barrel 1, the output shaft of the motor 8 passes through the upper part of the mixing barrel 1, the output shaft of the motor 8 is rotatably connected to the upper part of the mixing barrel 1, the output shaft of the motor 8 is fixedly connected to the top of the rotating shaft 2, the outer wall bottom wall of the mixing barrel 1 is fixedly connected to a discharge pipe 9, the discharge pipe 9 is installed with a valve, the outer wall top of the mixing barrel 1 is fixedly connected to a feed pipe 10, the outer end of the feed pipe 10 extends upward, and the top of the feed pipe 10 is fixedly connected to a funnel 11.

[0015] The middle stirring blade 5 is in the shape of a fan blade, and the upper and lower middle stirring blades 5 are mirror-symmetrical.

[0016] Since the scraper 7 is matched with the inner wall of the mixing barrel 1 and the gap between the scraper 7 and the inner wall of the mixing barrel 1 is very small, when the shaft 2 rotates, the scraper 7 can remove the residual material on the inner wall to prevent the material from adhering to the barrel wall during the mixing process, thereby ensuring the thoroughness and uniformity of the mixing.

[0017] Liquid material is injected into the mixing barrel 1 from the feed pipe 10, and the motor 8 drives the rotating shaft 2 to rotate, driving the lower mixing impeller 3, the upper mixing impeller 4 and the middle mixing blade 5 to rotate in the same direction. The lower mixing impeller 3 pushes the material upwards when rotating, and the upper mixing impeller 4 pushes the material downwards, thereby forming convection. At the same time, the middle mixing blade 5 stirs in the middle to accelerate the mixing of the material and improve the mixing efficiency. At the same time, the scraper 7 is driven by the connecting rod 6 to slide along the inner wall of the mixing barrel 1, and the material adhering to the inner wall of the mixing barrel 1 can be scraped off, and finally the valve of the discharge pipe 9 is opened for collection. The utility model only protects the mechanical part, and the functions related to it realized by the software control part are not within the protection scope of the utility model.
