Powder metallurgy raw material vibration screen

Abstract

The invention relates to a powder metallurgy raw material vibration screen. The powder metallurgy raw material vibration screen comprises a vibration screen body fixed to a machine frame. The vibration screen body comprises supporting rings and a separation net, wherein the supporting rings are fixedly connected with the machine frame. The edge of the separation net is fixedly connected with the inner walls of the supporting rings. The separation net is formed by elastic metal wires. A drive block is fixed to the middle portion of the separation net. A drive plate is arranged at the lower end of the vibration screen body. The drive plate is a semispherical plate corresponding to the semispherical appearance of the separation net. Fiber filaments are densely distributed in the semispherical plate. The middle portion of the drive plate is connected with a discharge pipe. A hammering block corresponding to the drive block is further arranged on the portion, corresponding to the position of the middle portion of the drive plate, of the end portion of the discharge pipe. The periphery of the drive plate is connected with the supporting rings through soft connection rings. An exciting motor is further synchronously fixed to the drive plate. Material separation is conducted through the vibration screen body which conducts periodic vibration through the hammering block, the exciting force generated by the hammering structure is larger compared with a regular vibration structure, and layering and separating of materials are better facilitated.

Description

technical field [0001] The invention relates to a powder metallurgy raw material vibrating screen, belonging to the field of powder metallurgy. Background technique [0002] Powder metallurgy is a process technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Therefore, powder metallurgy also has high requirements for the particles of raw material powder. If the particles are too large, the surface of the product will be rough, which will affect the quality, and the bonding force between the particles will also deteriorate, which will affect the performance of the product. Traditional vibrating screens It is easy to block the material. After a long time of use, it needs to be shut down for maintenance, and the filtration efficiency is low.
