Technical field
The invention belongs to contaminated soil remediation apparatus field, more particularly, relate to a kind of equipment for the gravel in contaminated soil drip washing reparation generation slime water, humus separation and separation method thereof.
Background technology
When carrying out the level process of band moisture to contaminated soil, often according to the composition of contaminated soil, screening process is carried out to contaminated soil, according to the size of particle diameter, step by step oarse-grained stone (particle diameter is greater than 10mm), coarse gravel (particle size range is 2-10mm) these be not easy contaminated composition remove, after simply washing, get final product qualified discharge, this process can be realized by traditional shaker subset.
Common shaker vibration intensity is large, and mesh size is less, and the thickness of screen cloth is also thinner, service life is shorter, therefore, common vibratory sieve cannot be installed the screen cloth of small-bore, even if install reluctantly, also can rupture because oscillation intensity is excessive very soon and come.Common vibratory sieve to fine sand (particle size range 0.2-2mm) almost complete absence of effect.Even if adopt the screen cloth of the small-bore of high strength; when vibratory sieve operation; because vibratory sieve uses as elementary screening Work machine; in use produce a large amount of fine sands; these fine sands can block screen cloth; cause screen cloth to lose efficacy, severe patient can cause discharge bucket below even to come off because buildup seriously ftractures with vibratory sieve junction.
Common vibratory sieve belongs to coarse fraction equipment, and treating capacity is large, and the power of consumption is large, and the noise produced during equipment work is also very large, and screening effect is poor.
