Screening machine with dislocation drawing-and-pulling type composite sieve

Abstract

The invention relates to a screening machine with a dislocation drawing-and-pulling type composite sieve. The screening machine comprises a machine shell and a rack. The machine shell is arranged on the rack, a feeding opening is formed in the upper portion of the machine shell, and a first discharging opening is formed in the bottom of the machine shell. The machine shell is internally provided with the dislocation drawing-and-pulling type composite sieve. According to the screening machine with the dislocation drawing-and-pulling type composite sieve, river sand is effectively subjected to coarse and fine separation sieving through the dislocation drawing-and-pulling type composite sieve, and the dislocation drawing-and-pulling type composite sieve cooperates with a push-broom unit, separation sieving efficiency is high, labor intensity is small, the time and labor are saved, the structure is novel, and the screening machine is suitable for large-area production, use and popularization.

Description

technical field [0001] The present invention relates to the technical field of screening equipment, more specifically, relates to a screening machine with a dislocation pull-type composite screen. Background technique [0002] Existing sieving machines use multi-layer or multi-stage sieving devices to sieve the size of the particles. The sieving machine uses the relative movement between the bulk material and the sieve surface to allow some particles to pass through the sieve holes, and the Sand, gravel, gravel and other materials are divided into different levels of vibrating screening machinery and equipment according to particle size. During the sieving process, the particles in the material whose particle size is smaller than the sieve size pass through the sieve surface and fall under the sieve, which is called undersize. Particles with a particle size larger than the sieve size remain on the sieve and are called oversize. Classifying sieves are widely used in the scr...

AI Technical Summary

Problems solved by technology

Because the vibration frequency of the vibrating motor is too frequent, there is a disadvantage of low screening efficiency when screening materials with large particle size differences, and only a single separation can be performed, and the production efficiency is low; the existing screening equipment occupies an area of Large, complex structure, low manufacturing cost, extremely prone to failure, high maintenance cost, and long maintenance time
