Problems solved by technology

The material spreading device rotates synchronously with the rotor. During use, the material spreading device cannot effectively disperse the material, and the concentration of the material curtain around the rotor is uneven, which seriously affects the classification accuracy of the rotor and the powder selection efficiency is low.

Abstract

The invention provides an efficient powder selecting machine with a power material scattering device. A lower part power material scattering device (10) is arranged at the lower part of the powder selecting machine; the lower part power material scattering device (10) is composed of a material scattering disc (16), a supporting device (17) connected with the material scattering disc (16), and a second transmission device (18) connected with the supporting device (17). The efficient powder selecting machine has the following technical effects that the power material scattering device is arranged at the lower part so that powder materials to be selected are sufficiently dispersed, and a stable and uniform flow field is provided for rotor grading the next step; the powder selecting efficiency is improved by 10%-15%; feeding is carried out at a lower part: the power selecting concentration of a rotor of the powder selecting machine is greatly reduced and the power consumption of the rotor is reduced by 15%-20%; discharging is carried out at the lower part: large-particle materials and iron blocks are directly discharged from the lower part of a discharging opening, the upper part sealing is not blocked, and the abrasion of an upper guide blade is small.

Description

technical field [0001] The invention relates to a high-efficiency powder separator with a power spreading device, belonging to the technical field of powder classification. Background technique [0002] The existing high-efficiency powder separator, the material spreading device and the rotor device are integrated, and the material is fed from the top. The material spreading device rotates synchronously with the rotor. During use, the material spreading device cannot effectively disperse the materials, and the concentration of the material curtain around the rotor is uneven, which seriously affects the classification accuracy of the rotor and the powder selection efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency powder separator with a power spreading device. [0004] The high-efficiency powder separator with power spreading device of the present inv...
