Description
Technical Field
[0001] The utility model relates to the technical field of mixers, in particular to an internal rotating mixer. Background Art
[0002] A mixer is a construction machinery, mainly used for mixing cement, sand, various dry mortar and other construction materials. It mixes various raw materials into a mixture or a suitable consistency by rotating the shaft with blades in a cylinder or trough. There are many types of mixers, among which the internal rotary mixer is a special type of mixer. The main feature of the internal rotary mixer is that its stirring paddle or agitator rotates inside the mixing tank. This rotation mode makes the materials in the mixing tank subject to various forces such as centrifugal force, shear force and traction, so as to achieve full mixing of the materials.
[0003] However, traditional mixers often have problems such as uneven material mixing and easy sticking to the wall during the mixing process, which not only affects the mixing effect, but also increases the difficulty of cleaning and reduces production efficiency. Especially for some sticky materials, once they are exposed to water, their adhesion will be significantly enhanced, and they are more likely to adhere to the inner wall of the mixer, resulting in reduced mixing quality and difficulty in cleaning. For this reason, we proposed an internal rotating mixer. Utility Model Content

[0026] A stirring blade 7 is arranged at the lower end of the rotating main shaft 6 and is used to stir the material in the inner cavity of the mixing drum 1;
[0027] The anti-adhesion device 14 is arranged at both ends of the connecting plate 15 and is used to remove the material adhered to the inner wall of the mixing drum 1 .
[0028] Furthermore, two racks 11 are fixedly connected to the upper and lower ends of the inner wall of the mixing drum 1. The racks 11 are ring-shaped, and the teeth on the racks 11 are all arranged inwardly.
[0029] Furthermore, the stirring blade 7 is fixedly connected to the lower end of the rotating main shaft 6 in a cross structure, and a plurality of inclined stirring blades are fixedly connected to the four sides of the stirring blade 7 .
[0030] Furthermore, the anti-adhesion device 14 includes a rotating countershaft 8, a follower gear 12 and steel bristles 13. The two ends of the connecting plate 15 are rotatably connected to the two rotating countershafts 8. The lower end of the rotating countershaft 8 is fixedly connected to two follower gears 12 corresponding to the two racks 11. The side of the rotating countershaft 8 is fixedly connected to a plurality of steel bristles 13 arranged equidistantly in a ring shape. The end of the steel bristles 13 away from the rotating countershaft 8 is in contact with the inner wall of the mixing drum 1.
[0031] Furthermore, the follower gear 12 is meshed with the rack 11 on the inner wall of the mixing drum 1 .
[0032] Furthermore, a plurality of scrapers 10 arranged equidistantly are fixedly connected to the bottom of the bottom connecting block 9, and the bottom surface of the scraper 10 is inclined.
[0033] Working principle: First, start the driving motor 4, and transmit the power to the rotating main shaft 6 through the gear box 5. Since the rotating main shaft 6 is connected to the connecting plate 15 in the mixing drum 1, the rotation of the rotating main shaft 6 will drive the connecting plate 15 and the mixing blade 7 fixed on the connecting plate 15 to rotate together. A plurality of inclined stirring bevels are fixed on all four sides of the blade 7, which can ensure that the material is fully and evenly stirred in the mixing drum 1. At the same time, the rotating secondary shaft 8 fixed at both ends of the connecting plate 15 also rotates with the rotation of the rotating main shaft 6. Since the lower end of the rotating secondary shaft 8 is fixed with a follower gear 12, these follower gears 12 and the mixing The racks 11 on the inner wall of the mixing drum 1 are meshed, and when the driven gears 12 rotate, they will move along the racks 11, thereby driving the rotating countershaft 8 and the steel bristles 13 fixed on the rotating countershaft 8 to perform circular motion along the inner wall of the mixing drum 1. The design of the steel bristles 13 can fit tightly against the inner wall of the mixing drum 1, effectively remove the materials adhering to the inner wall, and prevent the accumulation and blockage of the materials. The scrapers 10 fixed at the bottom of the bottom connecting block 9 will rotate with the rotation of the rotating main shaft 6. Since the bottom surfaces of the scrapers 10 are inclined, they can scrape off the materials accumulated at the bottom of the mixing drum 1, ensuring that the materials can be evenly mixed and preventing the generation of dead corners.
