Summary of the invention
For solving the problem, the invention discloses a kind of abrasion-resistant hollow brick containing Boccaro shale, water-absorbent is strong, wear-resisting, withstand voltage, antidetonation, and when baking bricks, energy consumption is few, and shrinking percentage is little, and production cost is low.
For achieving the above object, technical scheme of the present invention is as follows:
Containing an abrasion-resistant hollow brick for Boccaro shale, it is characterized in that: be made up of the raw material of following weight part: quartz sand 10-15 part, carbide slag 10-20 part, coal gangue 50-60 part, Boccaro shale 10-20 part, water 10-25 part, chalk soil 15-25 part.
Containing an abrasion-resistant hollow brick for Boccaro shale, its concrete preparation process is as follows:
(1) use jaw crusher, hammer mill carry out break process respectively to Boccaro shale, coal gangue, carbide slag, and after broken, particle size controls at 1-10mm;
(2) controlled the inlet amount of Boccaro shale, coal gangue by Central Control Room, pour stirrer into respectively by streamline and stir 6-10 minute, make it to mix;
(3) mixture after step (2) is entered twin rollers by streamline, high speed pair roller after spraying adds water, rotating speed is 300-400 rev/min, and after pair roller, particle size controls at 1-3mm, removes impurity;
(4) quartz sand, chalk soil are dried, remove impurity,
(5) chalk soil after the compound after step (3) and step (4) is entered ageing storehouse sealing ageing 30-36 hour by streamline, evenly add quartz sand, then seal ageing 28-36 hour, period spraying and moisturizing, keep temperature 25-30 DEG C, pressure 1-2MPa;
(6) brick press is entered after being mixed by the raw material after step (4) (5), by vacuumizing extruding and being cut into adobe pile on feeding car;
(7) after cooling 3-8 hour, feeding car is sent into 2-3 drying shed to dry, bake out temperature is 40-80 DEG C, and drying time is 10-30 hour;
(8) sintering oven is put in the adobe after step (7) to sinter, sintering temperature is 850-960 DEG C, and sintering time is 1-2 hour, and storage period, 18-30 hour, took out after cooling.
As a modification of the present invention, the adobe water ratio after described step (6) is 12-20%.
As a modification of the present invention, the adobe water ratio after described step (7) is 3-10%.
As a modification of the present invention, the adobe after described step (6) is of a size of 240mm × 190mm × 150mm.
As a modification of the present invention, be provided with 15 holes in the middle of the adobe after described step (6), each bore dia is 15-20mm.
As a modification of the present invention, outside the adobe after described step (6), be provided with lines.
The present invention makes hollow brick with coal gangue, quartz sand for main raw material, do not use cement, production cost is low, saved the soil that the mankind depend on for existence (clay) resource, coal gangue is the waste material after coal mining, and quartz sand is the waste in river course, utilize quartz sand to make hollow brick, can yangtze river channel be cleared up, make the smooth and easy navigation in river course, eliminate flood, utilization of waste material, energy-conserving and environment-protective, a certain amount of Boccaro shale is added in raw material, due to half diagenesis of Boccaro shale to be a kind of with clay mineral be main ingredient, iron-holder is higher and containing the composition of a great deal of flour sand level, smash rear and coal gangue, the hollow brick that quartz sand is made, solid, there are many small pores, can not be cracked because temperature sharply changes, again can not porcelain, hard not broken, there is comparatively strong absorptive, shrinking percentage is little, viscosity is high, have wear-resisting, withstand voltage, acid and alkali-resistance, anti-aging several functions such as grade, be mixed with the hollow brick quality soft or hard appropriateness of Boccaro shale, pollution-free, be applicable to people to the requirement of hollow brick, production technique of the present invention is simple, easy to make, ultimate compression strength is high, wear-resistant, when sintering in sintering oven, coal gangue sintering time at 700-800 DEG C of temperature is can start spontaneous combustion after 1-2 hour, save the coal charge of sintering, decrease waste gas to discharge, and coal gangue spontaneous combustion in adobe, adobe can be sintered from the inside to surface thorough, there will not be the uneven cracking phenomena caused of sintering.
Oven dry of the present invention utilizes the preheating of sintering oven to carry out, save coal charge, for reducing production cost, described drying shed is 3, drying sintering adopts the mode of " three dry a burning, semi-stiff extrusion process " to carry out, adobe after described step (6) all piles up on feeding car, feeding car is used to dry in 3 drying sheds respectively, enhance productivity, then all enter the disposable sintering of sintering oven, without the need to adobe being stirred, direct pile is fired on coaster, reduce hand labor intensity, reduce production cost.
The particle size of mixture controls at 1-3mm by the present invention in step (3), and the thicker water-absorbent of particle is better, but hollow brick intensity reduces, sintering temperature is high, surface irregularity, and the thinner water-absorbent of particle is poor, but hollow brick intensity improves, reduce sintering temperature, surface is fine and smooth, controls particle size at 1-3mm whole structure best by practice, water-absorbent can either be ensured, have and can ensure hollow brick intensity, save energy, surface is not coarse.
The present invention in step (4) to Boccaro shale, coal gangue, the mixture of chalk soil carries out sealing ageing, originally in its natural state ageing need 6-7 days can aquation and carry out ion-exchange, the performance of surface and inside is even, ageing of the present invention is at maintenance temperature 25-30 DEG C, give certain pressure, time only needs 2-3 days, and midway adds quartz sand ageing 30 hours again under the pressure of about 1-2MPa, what aquation and ion-exchange can be made to carry out is more abundant, improve the plasticity of raw material, can also redox reaction be accelerated. cause microorganism accelerates multiplication, make raw material evenly soft, and then reach increase plasticity, improve mobility and cementability, make raw material surface smooth, improve processability and the drying property of raw material, improve the quality of hollow brick, through the coal gangue Boccaro shale raw material of high pressure ageing, the dry scrap rate of product reduces 10%, sintering scrap rate reduces 8%, plasticity index improves 2-3, Aging Temperature is not less than 25 DEG C, winter production answers heating, spraying and moisturizing in ageing process, guarantee that ageing can be carried out smoothly, produce a desired effect.
In raw material, add a certain amount of chalk soil, the hollow brick processed through preparation method of the present invention plays anti-crack function, makes the excellent combination property of hollow brick, meets national standard.
Hollow brick of the present invention, compared with solid brick, can make buildings weight reduction 30-40%, saves clay more than 30%, fuel economy 20%-30%, and yield rate is high, weatherability is strong, cost reduces by 30%, and operating efficiency improves 40%, and can improve the water absorbing properties of brick.
