Description

Technical Field

[0001] The utility model belongs to the technical field of structure of grading impellers, in particular to a grading impeller with a dispersed structure. Background Art

[0002] The impeller classifier mainly uses a grading impeller to classify powders. The principle is to guide the powder to flow from the outside of the grading impeller to the inside through the airflow, and to classify the powder using the blade spacing of the decomposition impeller. Powder with appropriate particle size can enter the grading impeller and then be discharged with the airflow. Finally, the powder is collected by the bag dust collector. Powder with larger particle size is blocked outside the grading impeller, thus achieving the purpose of classification. Some materials are prone to agglomeration after crushing. The existing grading impeller lacks a dispersion structure for agglomerated materials, making it difficult to quickly complete the classification of agglomerated materials, which has a certain impact on the classification efficiency. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a grading impeller with a dispersing structure, which can disperse agglomerated materials simultaneously during the grading process, thereby effectively improving the grading efficiency of the materials.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A grading impeller with a dispersed structure comprises an impeller body, with a plurality of blades arranged in a circumferential array at the bottom of the impeller body. The blades are arranged radially along the impeller body, with the sides of the blades facing the impeller body's rotational direction tilted upward in the direction of rotation. The distance between the outer ends of the blades and the axis of the impeller body is greater than the outer diameter of the impeller body. The edges of the blades facing the impeller body's rotational direction are provided with notches, with multiple notches being provided along the length of the blades.

[0006] The beneficial effect of the utility model is that the rotation of the impeller body drives the blades to rotate together, so that the blades impact the agglomerated materials to disperse the agglomerated materials, thereby effectively increasing the chance of the agglomerated materials entering the classification impeller, and then improving the classification efficiency.

[0011] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0012] like Figure 1 As shown, a grading impeller with a dispersed structure includes an impeller body 1. A plurality of blades 2 are arranged in a circumferential array at the bottom of the impeller body 1. The blades 2 are arranged radially along the impeller body 1. In a radial projection view of the impeller body 1, the blades 2 are inclined relative to the axis of the impeller body 1. The side of the blade 2 facing the direction of rotation of the impeller body 1 is inclined upward in the direction of rotation of the impeller body 1. The distance between the outer end of the blade 2 and the axis of the impeller body 1 is greater than the outer diameter of the impeller body 1, so that the blade 2 can cover the space where the material rises. During the grading process, the blades 2 will rotate along with the impeller body 1, thereby breaking up the agglomerated materials so that the materials with qualified particle sizes can pass through the grading quickly, thereby improving the grading efficiency. During the rotation process, the blades 2 will also generate an upward attraction to the materials due to their special inclination angle and orientation, thereby accelerating the rising of the materials. The overall weight of the agglomerated materials will increase, making it difficult for the agglomerated materials to rise to the impeller body 1. After adopting this design, the airflow of the agglomerated materials is increased, and the agglomerated materials can be dispersed after rising, thereby further improving the grading efficiency of the materials.

[0013] Preferably, Figure 1 、 Figure 2 As shown, a notch 21 is provided on the edge of the blade 2 facing the rotation direction of the impeller body 1 , and a plurality of notches 21 are provided along the length direction of the blade 2 to improve the dispersion effect on agglomerated materials.

[0014] Preferably, Figure 2 As shown, the inner ends of the blades 2 are connected to the same circular ring 22, and the circular ring 22 is connected to the bottom of the impeller body 1 by screws, so that the circular ring 22 is used to connect multiple blades 2 into an integral structure to facilitate overall disassembly and assembly.

[0015] Preferably, Figure 1 、 Figure 2 As shown, the outer ends of the blades 2 are connected to the same support ring 23 to improve the structural stability and strength of the blades 2 and reduce the vibration of the blades 2 during operation. The support ring 23 is a circular structure and is coaxially arranged with the impeller body 1 to improve the dynamic balance of the grading impeller during rotation.

[0016] Preferably, the blades 2, the ring 22 and the support ring 23 are all made of plastic to reduce the overall weight and alleviate the load on the grading impeller.

[0017] Further preferably, the blade 2, the circular ring 22 and the support ring 23 are integrally formed to ensure overall structural strength.

[0018] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
