Abstract
The present invention discloses a fine screening seperator for soil remediation by a leaching method. The fine screening seperator for soil remediation includes a reservoir and a transmission support. The reservoir has an opening on its top surface. The transmission support is connected above the reservoir. The transmission support supports a conveyor belt, the conveyor belt is projectively overlapped with part of the reservoir or the full of the reservoir in a vertical direction, the belt surface of the conveyor belt is reticular, a feed inlet is disposed above the conveyor belt, the feed inlet is right above the reservoir or over the starting end of the conveyor belt. The preliminary screened soil is finely screened by utilizing the reticular conveyor belt, the small granular soil falls into the reservoir from meshes of the conveyor belt, and the large granular soil is discharged by the conveyor belt. The preliminary screened soil on the conveyor belt is repeatedly washed by spraying high pressure water by a spraying pipe high pressure water to perform repeatedly washing with the combination of a shower pipe, and the soluble pollutants and small granules in the soil smaller than the meshes of the screen the mesh of the screen mesh are fully separated, and are sent into the reservoir, thereby improving the ability of the pollution treatment.
Description
Technical field
The present invention relates to environmental pollution treatment apparatus field, be specifically related to a kind of elution method soil remediation dusting cover seperator.
Background technology
Along with the quickening of China's rapid development of economy and urbanization, process of industrialization, China's soil and groundwater pollution problem also becomes increasingly conspicuous, especially some industrial enterprises are in process of production due to operation or miscarriage, cause a large amount of pollutants to enter into surrounding environment, cause serious pollution, metallurgy industry is a wherein important class.Great environment and health threat, often in occupation of valuable city position, can be caused when these places can be used as agricultural or commercial use in discarded chemical pollution place, thereby need to abandon contaminated soil of site to former industry and repair.
At present mainly comprise soil moved in to improve the original method, curing/stabilizing, Soil leaching and phytoremediation technology etc. for the recovery technique of heavy-metal contaminated soil, wherein soil washing is the mainstream technology that current heavy metal pollution place is administered.
Summary of the invention
The object of the present invention is to provide a kind of elution method soil remediation dusting cover seperator that soluble contaminants in soil is fully separated with the fine particle that is less than screen cloth mesh.
The technical scheme that the present invention takes is:
A kind of elution method soil remediation dusting cover seperator, comprise liquid reserve tank and transmit support, end face opening on described liquid reserve tank, described transmission support is connected in directly over liquid reserve tank, transmitting support upper support has conveyer belt, described conveyer belt and liquid reserve tank partly or entirely in the vertical direction projection overlap, the zone face of conveyer belt is netted, the top of conveyer belt is provided with charging aperture, and described charging aperture is positioned at directly over liquid reserve tank or conveyer belt transmits initiating terminal top.
Described liquid reserve tank bottom is connected with mud circulation mixing pump.
In described liquid reserve tank, be provided with side by side two slush pumps, the outlet conduit of slush pump connects the discharge nozzle in liquid reserve tank outside.
Described conveyer belt top arranges the shower of corresponding conveyer belt, and described shower is arranged at directly over liquid reserve tank.
Described shower is arranged at the side of feed pipe towards conveyer belt direction of transfer.
Take after above technical scheme, beneficial effect of the present invention is:
1. the soil that adopts the conveyer belt of mesh-like to cross primary dcreening operation carries out dusting cover, and short grained soil directly falls in liquid storage tank from the mesh of conveyer belt, and bulky grain soil is discharged by conveyer belt, is beneficial to fully separating fast of size particles.
2. conveyer belt top is provided with shower, and the soil spray water under high pressure that body is crossed the primary dcreening operation on conveyer belt cleans repeatedly, and the soluble contaminants in soil is fully separated and brought into liquid reserve tank with the fine particle that is less than screen cloth mesh, has effectively improved pollution treatment ability.
3. in liquid reserve tank, be provided with two groups of slush pumps arranged side by side, in a pump housing fault, can start rapidly another, prevent from affecting because of equipment fault the carrying out of back segment treatment process.
4. liquid reserve tank bottom is connected with circulation stirring pump through pipeline, in liquid reserve tank, constantly stirs, and guarantees that graininess soil and heavy metal ion suspend in water, and prevents the precipitation of particle, is convenient to the extraction of slush pump.
