Technical field
The utility model relates to the domestic garbage resource field, is meant the sorting unit of metal in a kind of lime-ash that reclaims behind the consumer waste incineration especially.
Background technology
Along with China's rapid growth of economy, resource, the energy, environmental protection isostructuralism contradiction are more outstanding, and the resource of China per unit GDP and energy resource consumption are about 10 times of developed country, and the resource utilization of China is too low, and the shortage of resources problem is more and more outstanding.On the other hand, the raising of rapid economy development and quickening of urbanization process and living standards of the people, domestic waste generation constantly increase, and effective processing of domestic waste is particularly become important.At present, the main method of disposal of refuse has: landfill method, composting process, burning method, wherein waste incineration method are that rubbish is at high temperature burnt, and making combustible component is stabilizing gas through oxidation transformation, and not flammable composition changes inorganic matter (lime-ash) into.The waste incineration method not only can be protected environment, can also make full use of resource, is the inexorable trend of garbage disposal development.In addition, along with the increase of content of beary metal in the house refuse, the corresponding increase of the content of beary metal in the lime-ash causes lime-ash to become hazardous waste, in order to realize " innoxious " target of garbage disposal, just must do the processing in a dark step to the lime-ash of waste incineration.
Present cinder from refuse incineration, domestic processing method generally are directly to transport the landfill yard landfill, not only cause a large amount of recoverable metal losses, and long-term the stacking take a large amount of soils; Heavy metal (mercury, lead, chromium that lime-ash is contained; Copper ...) in burning process, can not generate, can not destroy, migration and conversion only take place; Finally enter environment with identical quantity, and through atmosphere, drinking-water; Channels such as food get into human body and damage, and slag promptly is one of " secondary pollution " source of burning disposal generation, do not meet the principle of energy-saving and emission-reduction.
The utility model content
The utility model provides the sorting unit of metal ingredient in a kind of effective recovery lime-ash, and its purpose is to overcome the defective of the easy generation of secondary pollution that prior art exists.
The technical scheme of the utility model is following:
The sorting unit of incineration ash of household rubbish slag; It comprises three grades of screening plants that are used successively, and said one-level screening plant is a screen pack, and said secondary screening plant comprises transport and magnetic separator de-ironing successively; Said magnetic separator de-ironing is near transport; Said three grades of screening plants comprise cylinder tramp iron separator, sand shaker, iron dressing machine, disintegrating machine, jigging machine and shaking table, and the isolated magnetisable material of cylinder tramp iron separator is sent into sand shaker, and the outlet of this sand shaker is connected with iron dressing machine; The cylinder tramp iron separator isolated non-/ weak magnetic substance sends into disintegrating machine, the outlet of this disintegrating machine is connected with the jigging machine inlet, jigging machine exports and is connected with shaking table.
As the improvement of the utility model, said screen pack is the stainless steel screen pack, and its aperture is 115-120mm.
As the further improvement of the utility model, said transport is a conveyer belt.
As the further improvement of the utility model, said magnetic separator de-ironing is the suspension type magnetic separator de-ironing, and it is positioned at the top of conveyer belt.
Can know that by above-mentioned description compare with prior art, the advantage of the utility model is to the utility model:
1, efficiently sorting and reclaim the metal ingredient in the incineration ash of household rubbish slag of the utility model has not only avoided secondary pollution ground to form, and the metal after reclaiming can be used effectively once more and obtains favorable economic benefit.
2, screen pack can filter out bulk noncombustibilities such as stone, fragment of brick and glass; The deironing function is adsorbed ironwork, and then ironwork is reclaimed; Cylinder tramp iron separator, sand shaker and iron dressing machine cooperatively interact and can reclaim granular magnetisable material; Cylinder tramp iron separator, disintegrating machine, jigging machine and shaking table cooperatively interact can reclaim granular non-/ weak magnetic substance.Therefore, the recovering effect of the utility model is comparatively desirable.
3, the utility model belongs to pure physics recovery, does not add any assistant chemical product, does not have intermediate product, therefore in the sorting removal process, can not produce new pollution, comparatively environmental protection.
Description of drawings
Fig. 1 is the frame structure sketch map of the utility model.
The specific embodiment
The specific embodiment of the utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, the sorting unit of incineration ash of household rubbish slag, it comprises three grades of screening plants that are used successively, and the one-level screening plant is a screen pack 1, and it can filter out bulk noncombustibilities such as the stone in the lime-ash, fragment of brick and glass; The secondary screening plant comprises conveyer belt 2 and suspension type magnetic separator de-ironing 3 successively, and suspension type magnetic separator de-ironing 3 is positioned at the conveyer belt top near conveyer belt 2 and its; Three grades of screening plants comprise cylinder tramp iron separator 4, sand shaker 5, iron dressing machine 6, disintegrating machine 7, jigging machine 8 and shaking table 9, and cylinder tramp iron separator 4 isolated magnetisable materials are sent into sand shaker 5, and the outlet of this sand shaker 5 is connected with iron dressing machine 6; Cylinder tramp iron separator 4 isolated non-/ weak magnetic substance sends into disintegrating machine 7, the outlet of this disintegrating machine 7 is connected with jigging machine 8 inlets, jigging machine 8 exports and is connected with shaking table 9.
