Water-saving and energy-saving sand and gravel aggregate washing system with desilting being performed first

Abstract

The invention discloses a water-saving and energy-saving sand and gravel aggregate washing system with desilting being performed first, and relates to the field of sand and gravel aggregate processing. The water-saving and energy-saving sand and gravel aggregate washing system mainly includes a dry material belt conveyor, a cleaning pool, a vibrating screen, a sand washing machine, a sedimentationtank and a clear water tank. The scheme of performing the desilting part of the entire water washing system first is adopted, firstly most of sand and mud in a mixture material are flushed out by using the cleaning pool, the remaining part is processed by a subsequently arranged flushing spray nozzle, the subsequent flushing water consumption is reduced, the risk of subsequent blocking of the vibration screen is reduced, meanwhile, the screening efficiency of the vibration screen is improved, and the probability of vibration screen maintenance is reduced. The water-saving and energy-saving sand and gravel aggregate washing system can be widely popularized to regions lacking water resources, realizes efficient utilization of water resources, and promotes sustainable development.

Description

technical field [0001] The invention relates to the field of sand and gravel aggregate processing, in particular to a water-saving and energy-saving sand and gravel aggregate washing system before desilting. Background technique [0002] At present, the wet washing process commonly used in the sand and gravel aggregate industry is water washing-dosing and sedimentation-press filtration-reuse. This method consumes a lot of water and produces a lot of sludge, and the desilting is concentrated in the screening process, which is likely to cause vibration. The sieve is blocked, thereby reducing the screening effect; it is also easy to cause a large increase in flushing water, and the flushing effect is not ideal. While wasting a lot of resources, it is not conducive to enterprises to reduce production costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a water-saving and energy-saving sand...
