Description
Technical Field
The utility model belongs to the field of hazardous waste pretreatment, and particularly relates to a landfill hazardous waste pretreatment system.
Background
The hazardous waste landfill is a final disposal process of the hazardous waste, and safe landfill can be carried out only after various indexes of the landfill waste are subjected to stabilization and solidification disposal and all the indexes reach landfill standards; however, some landfill wastes are large in volume and all indexes of the landfill wastes do not meet the landfill standard, and the landfill wastes can be safely buried after being subjected to stabilization and solidification pretreatment. In view of the situation, the wastes with larger volume need to be crushed and then stably solidified, and the wastes can be subjected to compliant landfill after reaching the landfill standard; it is therefore an object of the present invention to provide a landfill hazardous waste pretreatment system.
SUMMERY OF THE UTILITY MODEL
In view of the above technical problems, the present invention provides an efficient landfill hazardous waste pretreatment system.
In order to solve the technical problems, the utility model adopts the technical scheme that: the utility model provides a landfill hazardous waste pretreatment systems, includes jaw breaker, hammer crusher, shale shaker, jaw breaker's discharge gate with set up belt feeder a between hammer crusher's the feed inlet, hammer crusher's discharge gate with set up belt feeder b between the feed inlet of shale shaker, the shale shaker is provided with three discharge gate, is coarse fodder export, middlings export, the export of thin material respectively, the coarse fodder export with set up belt feeder c between jaw crusher's the feed inlet, the middlings export with set up belt feeder d between hammer crusher's the feed inlet.
Further, a magnetic suction device is arranged above the belt conveyor a.
Compared with the prior art, the utility model has the following advantages:
1. the method comprises the steps of crushing waste into small blocks by using a jaw crusher, crushing the small blocks by using a hammer crusher, screening by using a vibrating screen, screening out waste meeting the specification for subsequent treatment, simultaneously, conveying the coarse waste screened in the vibrating screen to the jaw crusher through a belt conveyor for re-crushing, conveying the waste with the medium volume to the hammer crusher through the belt conveyor for re-crushing, and sequentially circulating; by using the system, the waste to be buried can be treated to be finer and accord with the subsequent treatment specification, meanwhile, the un-crushed waste can be conveyed to the crusher again, the crushing efficiency can be improved, and the working efficiency of the waste landfill pretreatment can be improved.
2. The magnetic suction device is arranged above the belt conveyor a between the jaw crusher and the hammer crusher and can be used for removing iron in waste, so that other equipment is prevented from being damaged, waste iron can be recycled, and the environment is protected.
