In order to solve the problem of prior art, the invention provides a kind of method of utilizing domestic refuse processing and fabricating light cinder brick, it joins the multiple wastes such as high calcium coal gangue (high calcium shale) and domestic refuse by utilizing low-grade diatomite to mix, and produces ultramicropore high-strength light sintering heat-reserving brick.
The technical solution adopted in the present invention is as follows:
A kind of method of utilizing domestic refuse processing and fabricating light cinder brick, its method comprises the following steps:
A, get diatomite after pulverizing and sieving, domestic refuse, containing limestone serous composition 15%-30% the high calcium coal gangue as aggregate, add fluorite ore as toughener, add granules of polystyrene as the pore forming agent;
B, above raw material added water stir with stirrer, through ageing in 72 hours by the Vacuum brick making machine extrusion moulding;
C, molding semi product is used automatic hack cutter cutting, carry out at last 950 ~ 1000 degree high temperature sinterings, obtain finished product.
The mass ratio of diatomite, domestic refuse, high calcium coal gangue, fluorite ore and granules of polystyrene is respectively 58-60%, 14%, 25%, 1-3% and 0.004%, the fineness of diatomite, domestic refuse is below 2mm, the fineness of high calcium coal gangue is at 0.5 ~ 0.8mm, and the fineness of granules of polystyrene is at 1 ~ 2mm.
The high calcium coal gangue can use the high calcium shale of homogenous quantities ratio to replace.
Domestic refuse can use the sludge of sewage treatment plant after squeezing of homogenous quantities ratio to replace.
low-grade diatomite after the present invention will pulverize and sieve (the diatomite mine tailing after perhaps purifying), sludge of sewage treatment plant or domestic refuse after squeezing, high calcium coal gangue (the containing limestone serous composition 15%-30% of colliery discharging, if there is no the high calcium coal gangue, can use the high calcium shale with equal proportion to substitute, generally these two kinds of raw materials are because limestone content is too high, all can not be as brick-making raw material) as aggregate, add a certain proportion of fluorite ore deposit as toughener, (granules of polystyrene can obtain from domestic refuse as the pore forming agent to add a certain proportion of granules of polystyrene, generally, all this raw material can be arranged in domestic refuse, be exactly the lightweight polyphenyl vinyl foam plate of usually using as the packing of product in fact, after it is pulverized and get final product), above several raw materials are added suitable quantity of water to be stirred through stirrer, again through ageing in 72 hours by the Vacuum brick making machine extrusion moulding, cut to desired shape and size through automatic hack cutter, carry out at last 950 ~ 1000 and spend the left and right high temperature sintering, a kind of surface and the inner light-high-strength self-insulation baked brick that is distributed with ultrafine micropore have been obtained.With the unselected clay vitrified brick with the gas concrete insulating brick (building block) compare, in the requirement of satisfying ultimate compression strength simultaneously, reduced production cost, and had fabulous light thermal-insulation performance.This novel clinker brick formula; all raw materials all derive from life and industrial waste; solved the processing difficult problem of domestic refuse and industrial deslagging; solve problem of environmental pollution that solid waste causes; protected cultivated land resource, realized the recycle of solid waste and satisfied the needs of building energy conservation.
The high calcium raw material should strictly be controlled its broken fineness and mix dosage, otherwise may cause goods the quality problems such as lime blowing to occur, the broken fineness requirement of high calcium coal gangue (comprising high calcium shale) is at 0.5 ~ 0.8mm and following, and the broken fineness requirement of diatomite, domestic refuse and sludge of sewage treatment plant is below 2mm.Coal gangue and shale calcic (Wingdale) amount should be between 15 ~ 30, too low pore DeGrain, and also product unit weight can increase, granules of polystyrene smashing fineness 1 ~ 2mm.
