[0028] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0029] In the description of the present invention, it should be understood that the terms "top", "bottom", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0030] See also Figure 1 The utility model discloses a novel anchor-type spiral impeller in a specific embodiment, which is arranged in a container and can stir the material poured into the container. The impeller includes an elliptical spiral component 1, an agitator shaft 2, an anchor rod component 3 and an arcuate blade 4. The elliptical spiral component 1 is arranged on the agitator shaft 2 and can rotate with the agitator shaft 2. The elliptical spiral component 1 includes a plurality of spiral blades 11, which extend along the axial direction of the agitator shaft 2 to a set length, so as to drive the agitator shaft 2 to rotate when the agitator shaft 2 rotates to form an axial flow. The arcuate blade 4 is connected to the agitator shaft 2 and is located at the bottom of the container. When the agitator shaft 2 rotates, it can drive the arcuate blade 4 to rotate synchronously, so as to drive the material deposited at the bottom of the container to move, thereby preventing the material from being deposited at the bottom of the container for a long time.

[0031] Specifically, the curvature of the arc-shaped blade 4 is offset from the size of the fillet of the inner wall of the container by an equal distance, and of course the arc-shaped blade 4 can also be bent to one side to form an arc-shaped blade 4 with a folded angle. And the gap value between the arc-shaped blade 4 and the inner wall of the container is consistent, thereby avoiding collision between the arc-shaped blade 4 and the inner wall of the container during rotation, thereby affecting the working stability of the overall structure of the stirring paddle.

[0032] In addition, although the gap between the arc-shaped blade 4 and the inner wall of the container is small, due to the characteristics of the material, when some materials are severely compacted on the inner wall of the container, scrapers can be respectively provided on the arc-shaped blade 4 and the anchor rods 32 on both sides. The scrapers can rotate with the arc-shaped blade 4 and the anchor rods 32 on both sides. When the scrapers rotate, they contact the inner wall of the container to scrape off the materials adhered to the inner wall of the container. If the materials do not adhere to the wall seriously, no scrapers are required.

[0033] More specifically, in order to improve the stirring efficiency, a plurality of helical blades 11 are arranged in the container, and the plurality of helical blades 11 are arranged in an interlaced manner. Two helical blades 11 are arranged here, and the interlaced helical blades 11 are suitable for being directly cut as a whole to form two helical blades 11 of consistent specifications. When the stirring shaft 2 rotates, it can drive the plurality of helical blades 11 to rotate synchronously at the same time, and the plurality of helical blades 11 can stir the material stored in the container at the same time, thereby generating a more stable axial flow for the material in the container, thereby ensuring that the material in the container can be stirred and mixed more evenly.

[0034] See also Figure 2 , a bottom anchor rod 31 is also provided at the bottom of the container, the bottom anchor rod 31 is perpendicular to the stirring shaft 2, and one end of the bottom anchor rod 31 is connected to the helical blade 11, and the other end of the bottom anchor rod 31 is connected to the stirring shaft 2. Therefore, the setting of the bottom anchor rod 31 can stably fix the helical blade 11 and the stirring shaft 2 together, thereby increasing the connection strength of the blade. In addition, two side anchor rods 32 are also provided between the multiple helical blades 11, and the two ends of the two side anchor rods 32 are respectively connected to different helical blades 11, and the anchor plates on both sides are kept parallel to the inner wall of the container, and the two side anchor rods 32 and the bottom anchor rod 31 together constitute the anchor frame of the stirring paddle. When the stirring shaft 2 rotates, the anchor frame rotates synchronously with the stirring shaft 2, thereby completing the radial flow of stirring in the container, and through the mutual cooperation between the radial flow and the axial flow, the material mixing in the container is made more uniform.

[0035] The axial mixing of the material by the impeller is achieved by the arrangement of the ribbon blades 11, and can be pumped upward or downward, depending on the actual application conditions. For example, if it is necessary to pump downward, the mixed material is forced to move downward along the inner wall of the container, and when it touches the arc bottom of the container, it is deflected along the arc by the arc blades 4, and then flows upward back to the surface along the stirring shaft 2. It flows from the center of the surface to the inner wall of the container, and then is pulled down again by the ribbon blades 11. If it is necessary to pump upward, the mixed material is forced to move upward along the inner wall of the container, and after rising to the upper limit of the liquid level, it is deflected, and then flows downward along the stirring shaft 2 back to the bottom of the container, thereby realizing that the material flows from the inner wall of the container to the center, and then is pushed upward again by the blades of the ribbon blades 11. Such operation ensures that all areas in the container can be mixed, and no dead zone is formed, thereby effectively ensuring the mixing effect.

[0036] Specifically, in order to ensure the strength between the bottom anchor rod 31 and the two side anchor rods 32 and the stirring shaft 2 and the screw blade 11, the bottom anchor rod 31 is welded to the screw blade 11 and the stirring shaft 2, and the two side anchor rods 32 are welded to the screw blade 11. The connection strength of the screw blade 11 can be effectively increased by welding.
