Dual-layer multi-freedom-degree vibration screening device

Abstract

The invention discloses a dual-layer multi-freedom-degree vibration screening device which comprises a controller, a rack, a first screening mechanism, a second screening mechanism and a material box.The controller is mounted on the outer side of the rack. The rack is located on the outer side of the second screening mechanism. The first screening mechanism is located above the rack. The second screening mechanism is located above the first screening mechanism. The materiel box is located below the first screening mechanism. Materials directly fall into the material box after being screened by the first screening mechanism and the second screening mechanism. According to the dual-layer multi-freedom-degree vibration screening device, dual-layer multi-freedom-degree vibration screening isachieved, meanwhile, semi-automation can be achieved, the overall structure of the device is simple, and the manufacturing cost is low; and efficient screening can be achieved, the screening efficiency is greatly improved, meanwhile, work time is reduced, and industrial large-scale production can be achieved easily.

Description

technical field [0001] The invention belongs to the field of screening machinery, in particular to a double-layer multi-degree-of-freedom vibration screening device. Background technique [0002] Screening machinery is widely used in many industries such as coal, metallurgy, mining, chemical industry, food, etc. The current screening operation equipment uses the relative movement between bulk materials and the screen surface to make some particles pass through the screen holes, and sand, gravel, etc. Materials such as gravel and gravel are divided into different levels of vibrating screening machinery and equipment according to particle size. The particle level of sieving depends on the sieve surface, and the sieve surface is divided into three types: grate, plate sieve and mesh sieve. The grate is suitable for sieving large-grained materials, and the gap between the grate is 1.1 to 1.2 times the particle size of the underscreen, generally not less than 50 mm. The plate si...
