[0020] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the following will briefly introduce the drawings needed to be used in the embodiments. Obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can also be obtained according to these drawings without creative labor.

[0021] The utility model will be described in detail below in combination with the drawings and specific embodiments, and the embodiments cannot be described one by one here, but the embodiments of the utility model are not limited to the following embodiments.

[0022] In combination with Figures 1-6As shown, the utility model provides a kind of novel stirring paddle, including stirring shaft 1 and install upper layer stirring group 2, middle layer stirring group 3 and lower layer stirring group 4 on stirring shaft 1, stirring shaft 1 has cavity 5, upper layer stirring group 2, middle layer stirring group 3 and lower layer stirring group 4 all include multiple stirring vane group 6, stirring vane group 6 includes first blade 61 and the second blade 62 of sliding fit with first blade 61, and it is equipped with through-hole 611 on first blade 61 and second blade 62. First blade 61 is fixedly installed on stirring shaft 1, and second blade 62 is slidably fitted into cavity 5 with stirring shaft 1, in initial state, second blade 62 and first blade 61 are staggered arrangement, i.e. second blade 62 will be shielded to the through-hole 611 on first blade 61, while first blade 61 will also be shielded to the through-hole 611 on second blade, and material will not pass through through-hole 611. In the embodiment, in initial state, the leftmost through-hole 611 on first blade 61 can pass through material.

[0023] According to one embodiment of the utility model, power rod 7 is arranged in stirring shaft 1. Specifically, one end of second blade 62, which extends into cavity 5, has an inclined surface 622, and power rod 7 has a wedge-shaped portion 71 that cooperates with inclined surface 622. In use, the stirring shaft extends into the tank from above the tank, and power rod 7 extends out of the tank and is connected to a lifting device 72. Lifting device 72 drives power rod 7 to move up and down, thereby driving second blade 62 to move, causing second blade 62 to move relative to first blade 61, thereby adjusting the relative positions of the through-holes 611 on first blade 61 and second blade 62. When the material has a high viscosity, the through-holes 611 on first blade 61 and second blade 62 can be adjusted to overlap each other, and some of the material can pass through the through-holes 611, which is beneficial to improving the stirring effect and reducing energy consumption.

[0024] According to one embodiment of the utility model, a chute 8 is arranged on first blade 61, spring 9 is arranged in chute 8, sliding block 621 is arranged on second blade 62 and slidably cooperates with chute 8, and one end of sliding block 9 is fixedly connected to spring 9. When second blade 62 moves outward, sliding block 621 stretches spring 9, and when it is not necessary to leak through the through-holes 611, power rod 71 is reset, and second blade 62 is reset under the action of spring 9.

[0025] In addition, in the embodiment, the stirring vane groups 6 in upper layer stirring group 2 and middle layer stirring group 3 are all arranged obliquely, and the oblique angles are 15° and 45°, respectively. The stirring vane groups 6 in lower layer stirring group 4 are arranged horizontally. Such arrangement can strengthen the effect of each layer of stirring group. Upper layer stirring group 2 is used for material introduction, middle layer stirring group 3 is mainly used for strengthening mixing, and lower layer stirring group 4 is mainly used for preventing sedimentation.
