METHOD OF REWORKING GARBAGE OF TOWN DUMPS AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: reworking 0f domestic and industrial wastes town dumps.

SUBSTANCE: proposed method consists in profiling the dump territory in the course of accumulation, excavation and sorting-out of garbage at simultaneous separation of scrap metal, stones and incombustible building wastes. After profiling the territory, dump is divided into technological sites which are covered with peat (and sawdust if available). Sorting-out of garbage is performed by means of layer-by-layer cyclic surface reworking of technological sited by detents of rotary stump pullers and then by working members of stone-picking road-building machines at simultaneous mixing of peat (and sawdust if available) with garbage in depth of sites and shaking of coarse and then fine scrap metal, stones and incombustible building wastes in separators. Then garbage is loaded in bins of machines for removal from dump. Cleaned garbage is subjected to surface grinding by means of layer-by-layer milling with the aid of peat milling machines. Milled garbage crumb is subjected to drying together with peat and sawdust under action of solar radiation in summer or freezing-out in winter, after which it is stacked for storage and making briquettes used as domestic fuel. Device proposed for reworking garbage includes complex of profiling and hoisting machines, sorting-out site and briquetting presses. Sorting-out site is made in form of technological sites covered with peat and sawdust (if available). Technological base consists of peat machine complex cyclically working on technological site covered with peat (and sawdust if available); technological base is made from complex which includes rotary stump puller with separator and collecting bin for coarse scrap metal, stones and incombustible building wastes, stone picking machine with separator and collecting bin for fine scrap metal, stone and incombustible building materials, peat agitators, swath collectors and milled peat picking machines for regular gathering of dried crumb which is subjected to briquetting in peat presses.

EFFECT: possibility of removal of garbage accumulated in dumps during 10-15 years; enhanced ecological safety; low cost of method.
