Abstract

The invention relates to a method for producing a new building material from construction waste and industrial residue. The method comprises the steps of crushing the waste and used materials, mixing the crushed waste and used material with different volumes of fluxed slurry with caking property according to different molding requirements so as to prepare a material which can be processed into bricks and tiles, then, shaping the material, and burning the shaped material, thereby producing the new building material.

Description

A kind ofly utilize building waste, method that industrial residue produces new building materials

Technical field

What the present invention relates to is the land resources protection soil conservation in field, the refuse treatment of field of Environment Protection, the building wall material, roofing tile etc. of building materials field.

Background technology

The brick class of building by laying bricks or stones that construction industry uses is mostly clay brick, also a small amount of building block is had, the use of clay brick, this has just caused, and a large amount of soils is occupied, loss, meanwhile, the transformation in enormous quantities in old city, various places are bought again the region of departing from urban district and are used for toppling over, burying rubbish, after building waste being toppled over, buries, farmland just forever can not utilize; In addition, a large amount of inorganic industrial waste residues is also occupying in large quantity, is engulfing soil; Further, some municipal effluents, trade effluent are also constantly discharging, and these just seriously do not destroy environment, cause the severe contamination of environment.All these, all unrestrictedly engulfing the soil and water resources that the mankind depend on for existence, threaten the existence of the mankind.

Summary of the invention

The soil of depending on for existence to make the mankind can not be a large amount of loss, also in order to allow the environment gone from bad to worse make moderate progress, to take a turn for the better, also call to respond country, be supplied to as early as possible a kind of new alternative clay brick of construction industry, watt new material of construction, the invention provides a kind of new technique, technology, building waste, industrial residue etc. are processed through certain fragmentation, be blended into a certain amount of cakingagent employing trade effluent or municipal effluent in a large number again and make flux, be made into required brick, watt shape, be fired into new material of construction.

The scheme that the present invention takes is: inorganic refuse, industrial residue fragmentation is to certain granularity, according to different forming methods, be blended into the flux material with cohesive action of different ratios, i.e. cakingagent, mixed make walk shape or wet-milling granular, again according to different forming methods, be made into brick, watt shape, after its drying, enter in kiln and fire, under certain kiln temperature, the melting of flux material, flowing, penetrate into brick, watt each position pore in, work as brick, watt cool time, flux is vitreous state, rubbish particle is cohered, become the brick of semi-sintered condition, watt.

The invention has the beneficial effects as follows: solve the environmental pollution gone from bad to worse and occupying farmland that building waste causes, checked the impetus in the utilized farmland of day by day reducing, purified water resource environment, meanwhile, also met the building materials demand day by day increased.Tentatively compare produced new Brick for building and clay matter porous baked brick, new building materials have obvious advantage: dimensional standard, do not shrink; Due to its technical characterstic, determine new brick and there is the high performance of intensity, far above the vitrified brick of other raw material types; More because it is flux vitreous adhesion character, be again semi-sintered condition, the building waste raw material utilized, industrial residue are also mostly through pyroprocessing, so weathering resistance performance spy is good; In addition, also there is the advantage that day treating refuse amount is large, can large suitability for industrialized production be carried out; Further, there is at existing pottery, refractory materials, emery wheel etc. the industrial enterprise of kiln, can change the line of production and produce, have that cost is low, less investment, stream money less, the feature of instant effect.

Embodiment

The present invention puts together useless, the old mineral-type such as brick and tile, cement, soil, sandstone building waste, inorganic industrial waste residue etc., with jaw crusher by its fragmentation (slightly tiny can process with wheel roller), according to different needs, after sieve out grain size distribution (usually, rolling out not need after sieve).Can be single time broken, also can be mix regardless of ratio, fragmentation is to the granularity (also can be the first mixing fragmentation again regardless of ratio) of about below 4mm, after pulverizing, mixing or in sand shape solid materials single after pulverizing, according to different molding modes, add the slurry of the tool cohesive action of 1-10% difference amount again, make both remix make walk shape with common pug mill or mixer or wet-milling granular, extrusion molding or compression molding, make all kinds of required brick, tile-type, afterwards, then dry.Then, be sent in tunnel kiln and fire, also can fire in the kiln of other kinds, after firing certain temperature, namely become the new brick and tile material for building of half sintering shape.

When making roofing tile or road brick, the maximum median size of garbage crushing should be less than 1.0mm, and when making Brick for building, maximum median size should be less than 4.0mm;

The slurry of tool bond performance used, then process separately, it is the material of one or more tool flux performances, the Xylo-Mucine adding 1-10% makes suspension agent and cakingagent, according to different forming methods, add the water of 50-100% again, slurry made when being ground to the fineness of more than 100 orders in ball mushroom machine.The material with flux performance can be a kind of industrial residue, also can be a kind of slag, also can allocate with multiple slag charge.Water used can be municipal effluent, and also can be trade effluent, domestic water etc., salt water also can be quoted in place with good conditionsi.

Its technical process is as follows:

Broken, sieve that------shaping---dry---firing---dispatches from the factory to be mixed into agglutinating value(of coal) slurry.

Claims

1. novel process, the new technology utilizing building waste, industrial residue, waste water to produce new building materials, it is characterized in that these are useless, marine store is processed through fragmentation, according to different forming requirements, be blended into the fluxed slurry of the tool bond performance of different amount, make the material that can be processed into brick and tile shape, reshaping, is fired into new building materials.

2. novel process according to claim 1, new technology, be in mixed material, add a kind of flux type cakingagent, it is characterized in that: the melting of flux material, flowing under high temperature, and penetrate in each pore, form vitreousness when cooling, various granule materials is cohered.
