Description
Technical field:
The present invention relates to technology of producing cement, particularly the packing technique field of cement.
Background technology:
Deliver from first patent of invention of cement and had more than 200 years history so far, in the production and application practice in more than 200 years, the quality of cement improves a lot, and kind also develops into hundreds of more than from one.Enter 20th century the seventies, the world creates serious energy dilemma, national governments start the importance progressively recognizing save energy, play energy-conserving and environment-protective all trades and professions are glad, the upsurge of utilization of waste material, flyash, slag, slag, kiln ash, coal gangue, phosphorus slag, building solid castoff etc., once the trade waste of burden was brought successively to be applied to manufacture of cement as cement and concrete some through the effort of scientists to the mankind, particularly Portland blast furnace slag cement, in the cement products such as Portland pozzolana cement and Portland fly ash cement, the consumption of trade waste reaches 20%-70%, annual utilization has reached several hundred million ton, for environment of preserving our planet makes huge contribution.The first method in background technology, these industrial solid castoffs utilized be after cement clinker is mixed by design proportion with industrial solid castoff together with grinding make cement products and pack and sell, another kind of method becomes the powder of certain fineness to carry out hybrid packed sale by design proportion again with cement compound separate compiling cement clinker.The advantage of above-mentioned Packaging Method is: pack single, using method is easy.But due to the rigid inorganic solidification material of the such high water activity of cement clinker and gypsum to contact with the water vapour in air can produce lost efficacy, hardening phenomenon, only have the trimestral quality guaranteed period.According to the survey; some construction brigade all used aged cement every year; also have many enterprises; a lot of cement is had to suffer to scrap process every year; aged cement is used to cause hidden dangers in project; and cement being carried out to scrap be a kind of to environment protection irresponsible behavior, it is the extremely inharmonic phenomenon of one that the existence of this phenomenon and government advocate the design of building a conservation-minded society, and must manage correction immediately.The cement compound itself that coal powder, slag powders, slag, kiln ash, coal gangue, phosphorus slag, building solid castoff are worn into can not produce and solidify expired phenomenon, only just produce gelation when mixing with alkaline matters such as cement, its quality guaranteed period can reach the length of 1 year or several years.But expired once high active material (cement clinker gypsum) or make moist and scrap in the introduction, these adulterants are also by together as scrap handling.
Secondly, in background technology, cement compound and cement clinker scarcely originate from areal, cement compound needs to consume transport power from output with transporting to manufacture of cement, or cement clinker is transported to the output ground of cement compound, equally also there is transport power consumption, or the finished product of cement clinker grown place output delivers to purchase business there, purchase business is given after mixing or separate grinding, the transport power that same needs cost a lot of money, according to present case, the marketing radius of cement is about 800KM, the handling transportation cost of cement will account for more than 10% of cement total cost, haul distance is long to be caused production cost to cross the meagre passive situation of high profit annoying cement manufacturer all the time and cannot free.
Tsing-Hua University, China Mining University, the application number that Lan Zijia large international corporation gives co-applications in 2002 be 02158190.8 patent of invention disclose " dualization " wet cement and packaging thereof, deposit, transport the manufacturing technology of use and application method, it is characterized in that cement being divided into cloudy body and positive body two part, and based on cloudy body, with positive body for part, as long as mixed with positive body by cloudy body during use, this technology does not produce dust, SO aborning
2, NO
xand CO
2be conducive to industrial Sustainable development, the quality guaranteed period also can be extended, but By consulting literatures learns that this technology just had people in Europe, the United States, day and USSR (Union of Soviet Socialist Republics) and sets foot in before 50 years, stability because of product needs to be verified further, fails to put into production on a large scale and apply.
Goal of the invention: the invention provides a kind of production and transport cost for above-mentioned deficiency low, the quality guaranteed period controls easily, expired and waste probability is little and do not affect the manufacture of cement Packaging Method of the inner quality of product.
Secondly, because current cement type is very various, the formula of various cement is different with component content, what in background technology, changed products in cement mill is with high costs, cement products factory is made to be reluctant often to change kind (changing products) on demand, market is usually therefore caused to raise variety dullness, user cannot be purchased and produce actual waste or hidden dangers in project with the cement type of engineering counterpart, and by method of the present invention packaging, as long as grinding station changes, B component formula just can be changed products at any time, production various cement is without any loss.
Technical solution of the present invention:
