Abstract

The invention relates to an electric screening system which comprises an electric device and a screening device, wherein the electric device is formed in a manner that a motor drives a transmission device; the transmission device comprises a worm mechanism consisting of a worm and a worm gear, and a rotating shaft which is connected with the worm mechanism; the screening device comprises a bearing on the rotating shaft, a shell, a brush bracket fixed on the rotating shaft, two brushes which are mounted on the brush bracket, a screening groove, a screening net and a collecting device; the two brushes are arranged inside the screening groove; the screening net is fixed at the bottom of the screening groove; and the collecting device is arranged below the screening groove. When being screened, materials are stirred and squeezed by the brushes; screening nets of different models can be changed, thereby realizing multi-stage screening of the materials, greatly improving production efficiency and reducing energy consumption; by virtue of a mode of motor driven operation and a sealed working space, a working environment and working conditions are greatly improved; and the problem that a conventional vibration screen has difficulty in screening materials with large viscosity, much moisture and large fineness is solved.

Description

technical field [0001] The invention relates to a material screening technology, in particular to a high-efficiency electric screening system for deep processing of particle fineness of solid materials. Background technique [0002] At present, coal powder, fly ash, sand and other solid materials are usually classified and screened out by screening machinery according to the size of the materials. However, the commonly used vibrating sieve is very inefficient when screening materials with high viscosity and high moisture. In order to avoid the problem of difficult screening, it is necessary to dry the water first, which is a waste of energy. Especially for some materials needed for experimental research, it is necessary to maintain the original composition of the materials, and the moisture drying cannot be carried out first. Therefore, a high-efficiency electric screening system is needed to solve the above problems. Contents of the invention [0003] The invention aims ...
