Description
Technical field
The invention belongs to papermaking waste processing technology field, and in particular to a kind of recycling method of sandstone.
Background technology
Corrugated paper has been widely used for various products packaging field as a kind of important etc product, corrugated paper, such as
The packaging of food or digital product.As the production essential equipment of corrugated board, production of fluting base paper line adds in production
During work, screening out, sandstone, sludge, waste residue and waste water can be produced in slag removal particularly after pulping flow is existing
Technology is that the sandstone for waste paper, the waste residue of generation obtain after pulping, desanding directly fills, not by follow-up fiber
Separating step.
The prior art handles the sandstone produced in paper making process by way of security landfill, so-called peace
Full landfill is that obtained sandstone is transferred to local environmental protection administration periodically to clear and filled in specific place by manufacturer.But pass through
Detect, the sandstone produced in fluting medium pulping and slag removal accounts for the 15% of the whole discarded objects produced, and each produces per year
It is about 30 tons to measure the sandstone that the paper mill more than 60,000 tons produces daily, although comprising only a small amount of fiber scraps of paper in sandstone,
A small amount of fiber scraps of paper also can produce serious pollution because of the centralized processing of a large amount of sandstones.
In view of the above-mentioned problems, there is an urgent need for a kind of sandstone recycling method.
The content of the invention
It is an object of the invention to：In order to solve the fiber that the sandstone landfill disposal produced in production process of corrugated paper produces
Pollution, there is provided a kind of sandstone recycling method produced in corrugated paper production.
The technical solution adopted by the present invention is as follows：
A kind of sandstone recycling method produced in corrugated paper production, comprises the following steps：
(1) sandstone is recycled：It will be recycled after the sandstone produced in production process of corrugated paper and sewage, sludge, waste residue separation；
(2) mixed processing：The sandstone and cinder are mixed to get primary mix；
(3) after-treatment：Primary mix progress after-treatment is obtained into mixture；
(4) mixture recycles：The mixture and respective material are configured to other products.
Further, the production process of corrugated paper refers to pulping, scalping, pressure hole sizer, vanning, slagging-off stage.
Further, the mass ratio of the sandstone in the step (2) and cinder is 6:5.
Further, it is that the mixture is made coal with organic bond PVA that mixture, which recycles, in the step (4)
Slag filler.
Further, it is by the mixture combination coal tar, pitch, perlite that step (4) mixture, which recycles,
Adsorbent is made.
Further, it is by the mixture and quartz, clam shell, clay, bastard coal that step (4) mixture, which recycles,
It is made of stones into refractory brick.
Further, the after-treatment described in the step (3) includes, by primary mix by pulverizer crushing at
Reason, then soaked with flowing water, finally primary mix is dried to obtain mixture.
Further, when the primary mix with flowing water soaking time is 4-8 small.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, the present invention in, by the sandstone produced in paper making process mixed with cinder and after-treatment after mixed
Thing, is made other products and is used as its way, 100% recycles, and avoids directly filling sand after mixture is mixed with respective material
Stone produces fiber contamination, while mixture can be used for multiple use, directly produce economic benefit, and the recycling beneficial to sandstone is sharp again
With.
2nd, in the present invention because sandstone be pulping, remove the gred, screen out during produce, therefore the volume of sandstone will not be too
Greatly, at this time by sandstone and cinder with 6:5 ratio mixing, can make sandstone and cinder mixing in mixture fully keep cinder original
Physical property, while cost will not be increased using cinder because of excessive.
3rd, in the present invention, cinder filler is made by adding organic bond into mixture, the cinder filler is without poisonous
Harmful substance, is a kind of new environmentally friendly filler.Not only cheap, high mechanical strength, antiseptic property is strong, compares table
Area is big, has preferable chemical stability, is easy to microorganism attachment, is not easy to block, easily controllable, it is possible to achieve to regenerate, again
It is multiple to utilize.
4th, in the present invention, it is low that mixture combination coal tar, pitch, perlite are made adsorbent production cost, it is modified
Mixture effectively raise adsorption efficiency as adsorbent.
5th, in the present invention, refractory brick is made in the mixture and quartz, clam shell, clay, gangue, can not only be realized
Waste utilization, moreover it is possible to effectively reduce the cost of refractory brick.
6th, in the present invention, after sandstone and cinder pulverization process, immersion, the mixture that drying is for making removes
Physical property is more outstanding while harmful substance.
7th, the present invention in, by cinder immersion 4-8 it is small when beneficial to remove mixture in noxious material, after mixture
It is continuous to recycle.
