Description
Technical field
The present invention relates to a kind of manufacture method of material of construction, be specifically related to a kind of method that municipal sludge makes floor tile.
Background technology
Along with the quickening of Urbanization in China, treatment rate of domestic sewage improves year by year, and number and the sludge yield of municipal sewage plant also increase thereupon.At present, the sludge quantity (dry mass) that municipal sewage plant of China discharges every year is about 1,300,000 t, and increases rapidly with the speed of annual growth 10%.Sludge pollution thing has long term toxicity and non-biodegradable, if let alone unordered discharge, will become dangerous secondary pollution source, enter food chain by media such as air, underground water, surface water and soil, serious threat is to human health.Therefore, how properly to dispose municipal sludge, become the problem of domestic and international extensive concern.At present, be one of important channel of city sewage sludge reclamation using sludge incineration ash as the spike of vitrified brick, but due to its production process energy consumption excessive, required high cost, is not promoted effectively in China so far.
Summary of the invention
The object of this invention is to provide a kind of method utilizing municipal sludge to produce excellent property, energy-conserving and environment-protective, floor tile that cost is low.
Municipal sludge makes a method for floor tile, comprises the following steps:
(1) by water ratio be more than 80% municipal sludge add be equivalent to mud weight 28-35% unslaked lime, 5-8% plant ash mixing and stirring, 7-10 days is deposited in ageing, makes its water ratio≤60%;
(2) municipal sludge of water ratio≤60% is sent in agitator through conveying belt, add stalk coatedparticles, cement slurry, river sand, alum ore deposit tailings, potter's clay, modified meerschaum, volcanics, zeolite, coconut husk charcoal to agitator simultaneously, under 150-200r/min rotating speed, be stirred into mixing pug, wherein the weight part of each raw material is as follows: municipal sludge 50-60, stalk coatedparticles 5-8, cement slurry 5-10, river sand 14-16, alum ore deposit tailings 12-15, potter's clay 8-10, modified meerschaum 3-5, volcanics 10-15, zeolite 15-25, coconut husk charcoal 5-10;
(3) above-mentioned obtained compound is stacked ageing 2-3 days;
(4), after the mud after ageing being carried out pugging, brick press is sent into, by extruding and being cut into adobe;
(5) pile up neatly by shaping adobe, after drying in the shade under natural condition 3-5 days, forced air drying 20-24h at 105-120 DEG C, makes its water ratio be 10-15%;
(6) send into stove sintering, sintering temperature is 1020-1040 DEG C, after grilling thoroughly adobe, is cooled to room temperature kiln discharge and gets product brick.
Described stalk coatedparticles is obtained by the raw material of following weight part: wilkinite 20-30, plant straw powder 18-24, water glass 20-25, carboxymethyl cellulose 0.5-1, clay 5-8; Preparation process is as follows: add in high-speed mixer by after wilkinite drying with carboxymethyl cellulose; speed with 500-800rpm at 110-120 DEG C is uniformly mixed 20-30min; after adding water glass continuation stirring 10-15min again; then plant straw powder, clay is added with the blended 5-10min of the speed of 1000-1500rpm; granulation in tablets press is sent into after drying; size controlling, at 2-4mm, obtains stalk coatedparticles.
Described modified meerschaum is prepared by following method: be placed in 400-450 DEG C of kiln kiln roasting 2-3h, pulverizes and grinds to form 100-150 order powder, namely obtain modified meerschaum after porphyrize.
Beneficial effect of the present invention:
The present invention, by formula adjustment and process modification, utilizes the coated wilkinite of plant straw powder, can significantly improve water tolerance and the intensity of floor tile; Modification is carried out to sepiolite, the adsorptivity of the objectionable impuritiess such as its obnoxious flavour that floor tile is discharged in use, heavy metal can be improved.The produced floor tile of the present invention does not have light weight, intensity is large, water-tolerant, yielding, the advantage such as safety nuisance free, environmental protection and energy saving.The inventive method is simple, easy to operate, and raw material sources are extensive, and with low cost, save energy, decreases any discharge of municipal sludge, have good Social benefit and economic benefit.
