Single-layer-multi-stage full-automatic vibration screening system

Abstract

The invention discloses a single-layer-multi-stage full-automatic vibration screening system which comprises a supporting frame, a feeding and discharging system, a sealing screening box and a conveying system are arranged on the supporting frame, the conveying system is arranged on the supporting frame, the feeding and discharging system is arranged on the two sides of the conveying system, the sealing screening box is arranged above the conveying system, and the sealing screening box is arranged above the conveying system. The sealing screen box conducts screening in a vibration mode and comprises a sealing box body, a single-layer-multi-stage screen face is arranged in the sealing box body, the screen face achieves graded switching of the aperture of circular screen holes through a linkage structure, and materials are downwards guided into the single-layer screen face from one side of the sealing box body to be subjected to multi-stage vibration screening. And the screened materials are guided out through the discharging system. The screening system designed by the invention adopts a single-layer-multi-stage screening system, and is combined with a double-vibration driving motor and a conveying system to repeatedly screen stones and automatically discharge the stones; secondly, a closed structure is adopted, dust dissipation is little, and the requirements for green, clean, environment-friendly and civilized construction are met.

Description

technical field [0001] The invention relates to the technical field of engineering screening equipment, in particular to a single-layer-multi-stage automatic vibrating screening system. Background technique [0002] In engineering fields such as water conservancy and ore dressing, the analysis of particle size distribution parameters of crushed stone is very important for the optimization of blasting parameters and the selection and utilization of stone materials. Therefore, the particle size screening test of crushed stone is the basis and key link of many projects. [0003] At the field construction site, the screening of gravel, crushed stone and other materials is mainly carried out manually with screen surfaces of different apertures, through which screens with different apertures produce several specifications of oversize and undersize, and finally obtain different particle sizes. diameter stone chips and weigh them. This screening method is simple to operate, but the...

Problems solved by technology

However, the technology disclosed in this patent has the following problems: 1. The scheme is a square-aperture screen surface, which is only suitable for sand and gravel screening processes such as housing construction, and cannot meet the strict requirements of earth and stone materials in geotechnical engineering fields such as mining, water conservancy, and earthwork engineering. Aperture (circular) screening requirements; 2. The scheme has a small range of screening positions after actually changing the aperture, and the difference between the outer and inner apertures is large (the outer aperture is getting larger and the inner aperture is getting smaller and smaller) ), resulting in uneven screening; 3. The spacing between two adjacent gear levers is controlled by springs, and the actual force between the springs at different positions has a certain difference, so that the aperture at the desired position (inner There is also a certain size difference, which leads to further uneven screening
