Detailed Description
The technical scheme of the present utility model will be described in detail with reference to the following examples and the accompanying drawings.
As shown in figure 1, the household and garden garbage composite treatment system comprises a sorting module, an aerobic fermentation module and a finished product module.
The sorting module is used for sorting household garbage and comprises a coarse crusher, a drum screen and a star plate screen, wherein the coarse crusher, the drum screen and the star plate screen are sequentially connected through a conveyor. The coarse crusher can crush the primary household garbage into small-particle-size materials, an iron remover is arranged between the crusher and the drum screen, iron substances in the crushed household garbage are removed, and the crushed household garbage is transported to the drum screen by the conveyor and is screened to obtain oversize products of the drum screen and undersize products of the drum screen. The oversize products of the drum screen are continuously transported to the star plate screen by the conveyor and are screened again to obtain oversize products of the star plate screen and undersize products of the star plate screen, and the oversize products and the undersize products of the star plate screen enter the corresponding next module respectively.
The aerobic fermentation module comprises a biomass crusher, an aerobic cabin and an air separator, and the biomass crusher, the aerobic cabin and the air separator are connected through a conveyor in sequence. Firstly, garden garbage is crushed into small-particle-size materials through a biomass crusher, the small-particle-size materials are transported to an aerobic cabin through a conveyor, meanwhile, the undersize materials of a drum screen and the undersize materials of a star-screen are also transported to the aerobic cabin through the conveyor, and wood chips and rice hull powder can be added in the process to serve as an alternative scheme for increasing carbon sources. After a period of aerobic fermentation, the fermented product is conveyed to a winnowing machine to generate oversize products of the winnowing machine and undersize products of the winnowing machine, and the oversize products and the undersize products respectively enter the corresponding next modules.
The finished product module comprises a granulator, a fine crusher, a compression dehydrator and a packer; the fine crusher, the compression dehydrator and the packer are connected in sequence through a conveyor. The oversize material of the winnowing machine can be mixed with wood dust and rice hull powder, and the mixture is sent into a granulator through a conveyor to prepare RDF (refuse derived fuel, refusedrifuel), and can be used as fuel of a cement plant, and the undersize material of the winnowing machine can be used as clay raw material of the cement plant. The material on the star plate screen is sent into a fine crusher through a conveyor, iron removers are arranged between the star plate screen and the fine crusher, iron substances in the material on the star plate screen are removed again, the material is crushed into materials with smaller particle size through the fine crusher, the materials are extruded and dehydrated through a compression dehydrator, and the materials enter a packer, and finally the RDF finished product is prepared and can be used as fuel of a cement plant.
Wherein the coarse crusher is a double-shaft crusher; the fine crusher is a single-shaft crusher; the compression dehydrator is a spiral extrusion dehydrator; the granulator is a disc ring die stamping granulator.
