Wrapping type ore sand screening device based on environmental engineering

Abstract

The invention discloses a wrapping type ore sand screening device based on environmental engineering. The wrapping type ore sand screening device comprises a first support arranged on the ground, a screening plant arranged on the first support, a feeding hopper arranged above the screening plant, and a material box arranged below the screening plant. The screening plant comprises a shell body arranged on the first support, a screening barrel arranged in the shell body, a motor arranged in the shell body, a rack arranged below the screening barrel and distributed in the radial direction of thescreening barrel by one cycle, a first gear arranged on the motor and meshing with the rack, and an isolation plate arranged at the upper end of the shell body. By means of the shell body and the screening barrel and the internal screening mode, less dust flies away, a working environment of a construction site is ensured, and health of workers is ensured; and by means of the screening barrel andthe rotating mode, internal materials are rolled over, filtering quality is effectively increase, and sand stone yield is increased.

Description

technical field [0001] The invention belongs to the technical field of ore sand screening, in particular to an enveloping type ore sand screening device based on environmental engineering. Background technique [0002] The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. The screening machine for mining includes a frame, a screen set on the frame, and a driving mechanism that drives the screen for vibratory screening. The screen surface of the screen is arranged obliquely, and the materials to be screened are introduced from the higher end of the screen. The screened materials of various particle sizes are discharged from the lower end of the screening machine. [0003] In daily use, the screening process is usually...

Problems solved by technology

[0003] In daily use, the screening process is usually accompanied by relatively large dust, and the flying dust greatly affects the working environment on the construction site, and the flying dust is often inhaled into the lungs by the workers during the breathing process, resulting in long-term exposure of the workers. The working environment will cause damage to the lungs. At the same time, the existing slope method is usually used to allow the material to slide down during the shaking process. However, the residence time of the material on the screen is short in this way, and it cannot be fully screened. Make the product yield after sieving less
