Description
Technical field
The utility model relates to a kind of processing unit (plant), refers more particularly to a kind of spray screening machine for contaminated soil.
Background technology
At present, the soil contamination problem caused due to various pollutant is day by day serious, in the existing arable land of China, about nearly 1/5 is subject to pollution in various degree, not only cause grain drop in production simultaneously, also cause heavy metal contaminants content overproof in crop, and be enriched in human body and animal by food chain, harm human and livestock health, causes human cancer and Other diseases etc.In addition, after soil is polluted, heavy metal, due to the non-biodegradable of itself, needs just can be accomplished for a long time so depend merely on self-purification after soil pollution; Meanwhile, because heavy metal has again stronger mobility in soil, be easy to, to water body and plant migration, cause the chain reaction of environment, cause pollution of food chain, thus affect health further.
The physical method of heavy-metal contaminated soil reparation mainly contains soil replacement method, heat treating process etc.Soil replacement method is a kind of effective contaminated soil physical treatment method, and it is by ploughing deeply soil bottom or covering cleaning soil or the methods such as changing cleaning soil that scooped away by contaminated soil on contaminated soil by contaminated soil.Contaminated soil and the ecosystem can be isolated by soil replacement method effectively, thus reduce its impact on environment.But the method is because quantities is large, costly, that be only suitable for small size, that soil pollution is serious situation.Meanwhile, polluter taking-up also can not be produced certain risk to environment.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the practical and convenient spray screening machine for contaminated soil.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of spray screening machine for contaminated soil, comprise housing, spray equipment, auger conveyor and accumulator tank, auger conveyor is provided with in described housing, described housing is provided with multiple screening hole, the top of described housing is provided with spray equipment, and the below of described housing is provided with accumulator tank.
Further, described spray equipment comprises back water pump, fluid reservoir, shower nozzle and shower, the overfall of described accumulator tank is connected with the entrance point of described back water pump, the port of export of described back water pump is connected with the entrance point of described fluid reservoir, the port of export of described fluid reservoir is provided with described shower, described shower is provided with multiple described shower nozzle and is evenly distributed on the top of described housing.
Particularly, described auger conveyor comprises rotating cylinder, hollow shaft and driving wheel, and described hollow shaft is provided with described driving wheel, and described hollow shaft is connected with described rotating cylinder, described rotating cylinder is provided with scalping hole and continuous print helical blade.
Further, the side of described auger conveyor is provided with speed changer, and described speed changer is connected with described augur by bearing.
The beneficial effects of the utility model are, the utility model is by the mode of regrading, by hardening in soil, the mode of block by screening carries out spray process, harden in sweetening of the soil the content of beary metal of block, and by the mode of chemical removal, leacheate is focused on, thus heavy metal effectively can be removed from soil, reach the object of cleaning soil.
