Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] The embodiment of the present invention discloses a method and system for making building materials from stale garbage. The method uses humus slag screened out of stale garbage as raw materials to make building materials, and realizes the fine screening of stale garbage, making the garbage in the The residual value of available resources has been fully utilized; at the same time, the content of humus in stale garbage is extremely high, and regenerating i...

Abstract

The invention discloses a method and a system for manufacturing building materials by using stale garbage. According to the method, the building material is prepared by taking humic muck screened outfrom the stale garbage as a raw material, and compared with sorting of different components of the stale garbage in the prior art, the method has the advantage that the accuracy is higher so that theresidual value of available resources in the garbage can be fully played; according to the system, manual sorting, magnetic separation, hot air separation, screening and crushing devices are combined, the process is well-organized, high-efficiency separation of magnetic substances, combustibles, the humic muck, large plastic blocks, large rubber blocks and other recyclable objects in the stale garbage can be achieved, so that accurate sorting and highly recovery of recyclable resources in the stale garbage can be realized; and meanwhile, due to the fact that the content of the humic muck in the stale garbage is extremely high, the muck is regenerated into the building material, a large amount of soil taking land can be saved every year, and the extremely good environmental protection benefit and social benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, and more specifically relates to a method and system for making building materials from stale garbage. Background technique [0002] At present, more than 60-70% of urban waste in my country is disposed of by landfill. Domestic waste has been landfilled for many years. After physical, chemical and biological reactions, the degradable substances are basically completely degraded. The properties and components of the waste are relatively stable, and a kind of humus soil similar to soil will be formed. This kind of humus is mostly used to improve the soil or make organic fertilizer. [0003] However, when humus soil is used to make organic fertilizer, special fermentation fertilizer facilities are required, which not only takes up a lot of land, but also costs relatively high; moreover, due to the complex composition of stale waste, it is difficult to efficiently screen, resulting in low ...
