Description
Technical Field
The utility model relates to the field of stirring devices, in particular to a gradual change arc-shaped section energy-saving stirring paddle.
Background
The stirring paddle mostly adopts a folding paddle, blades of the folding paddle are flat plates, an included angle is formed between the blades and the revolution surface, the included angle is about 30-45 degrees, and the inclination direction is opposite to the rotation direction of liquid flow. In use, the following problems are found: 1. because the blade of the blade folding paddle is an inclined plane, the liquid flow is suddenly folded when meeting the blade, and larger resistance is generated; 2. after the fluid is subjected to turning in the flow direction of the blades, the fluid is not completely discharged from the lower parts of the blades, but is mostly discharged from the lower parts of the blades, so that the stirring performance is reduced; 3. when the diameter of the paddle is large, the blade is easy to break or deform, the strength is not enough, the deformation problem is solved only by increasing the thickness of the blade, and the manufacturing cost is increased. Therefore, the stirring effect and the energy consumption index of the folding blade paddle are both low.
Therefore, in order to overcome the defects of the prior art, an energy-saving stirring paddle with a gradually-changed arc-shaped cross section needs to be designed to solve the problems.
