Description
Technical field
The invention belongs to the making method field of building brick, particularly a kind of making method of clinker brick with central blind hole made from full fly ash.
Background technology
The buildings vitrified brick is clay brick, shale brick, spoil brick, flyash brick at present.Mostly existing coal ash sintering brick is flyash is mixed in the clay, forms through stirring, extrusion moulding, oven dry, sintering.Do binding with clay, there are three big deficiencies in extrusion moulding: the one, and flyash is difficult for and the abundant mix of clay, has increased producting process difficulty, and power consumption height in the production process is mixed external fuel added into firinghole of a kiln in also wanting, and energy dissipation is big, the cost height; The 2nd, in order to guarantee extrusion moulding, the flyash mix proportions is lower, and general volume ratio has strengthened the consumption of clay about 20%～50%, wasted natural resources; The 3rd, can only produce the through hole hollow brick, masonry strength be cannot say for sure to demonstrate,prove, and metope easily cracks.
Summary of the invention
The objective of the invention is in order to overcome existing coal ash sintering brick making method above shortcomings, provide a kind of can save energy, reduce cost, reduce the waste of natural resources, administer pollution and the accumulation flyash land occupation of power plant, produce the making method of the clinker brick with central blind hole made from full fly ash of high-quality high strength blind hole hollow brick environment.
The objective of the invention is to realize by following technical proposals:
The making method of clinker brick with central blind hole made from full fly ash, the weight ratio of the moiety of described brick is flyash 96%～98%, the additive 2%～4% of fluxing, making method comprises the steps, the flyash that a. will account for whole flyash weight 15%～20% is dried back levigated pre-treatment; B. add the additive of fluxing; C. add surplus flyash; D. force to stir; E. extrusion forming; F. sintering.
The additive main component of fluxing is potassic mineral, or contains the mineral of sodium, potassium, or the paper mill effluent enriched material of compounds containing sodium, or potassium-bearing mineral ore dressing waste, or contains the waste of sodium potassium mineral ore dressing.
Potassic mineral are feldspar in powder, and the mineral that contain sodium potassium are the nepheline powder, and the paper mill effluent enriched material of compounds containing sodium is a caustic soda waste soda ash solution thing.
Oven dry utilizes the hot blast of sintering process emptying to do thermal source, adopts the air-flowing type oven dry, or drum-type drying, or the fluidized-bed oven dry.
The levigate of preprocessing process is levigate to-200 orders through ball mill.
Do not add water when adding surplus flyash, the water content of flyash must be less than 7%.
During extrusion forming three exhaust moulding of classification pressurization, from 0kg/cm
2Be forced into 50kg/cm
2After, carry out exhaust 2 seconds that stopped to pressurize; Continue to be forced into 100kg/cm again
2After, exhaust in 2 seconds stops to pressurize; Continue to be forced into 150kg/cm again
2After, exhaust in 2 seconds stops to pressurize; Be forced into ultimate pressure 200kg/cm then
2Moulding.
The invention has the beneficial effects as follows that flyash content has strengthened the utilization of coal ash rate of generations such as thermal power plant up to 96%～98% in the component, utilization of waste material has reduced improvement pressure; Flyash becomes the raw material and the fuel source of vitrified brick, does not need carbonaceous materials added to raw materials in the component of brick, economizes on coal 100%, classification extrusion forming technology economize on electricity 50%; Do not add water when adding surplus flyash, need not dry operation after the extrusion forming, saved the energy, cost descends more than 60%; Work in-process water content after the moulding is extremely low, not stratified, and the truncation arrisdefect has not overcome the deficiency that extrusion moulding can only be produced the through hole hollow brick, can produce Brick with blind hole, the blind hole vitrified brick masonry strength height of production, and metope does not crack.As seen, adopt the present invention of above-mentioned making method, have the saving natural resources, save energy reduces cost, but the advantage of production high-quality high strength blind hole hollow brick.
