Description

It shines and inhales the method that phosphorous tobacco stalk squeezes out the porous sponge brick that catchments of particle preparation

Technical field

The present invention relates to the methods that luminous suction phosphorous tobacco stalk squeezes out the porous sponge brick that catchments of particle preparation, belong to material Technology is led.

Background technology

Due to EI Nino and La Nina Phenomenon, there is extreme variation in the weather in China, and rainfall distributed pole is uneven, south Northern drought and waterlogging are uneven, and rainfall is also extremely unequal in the same area, 1 year, and water shortage has restricted expanding economy and the people Life rationally utilizes existing precipitation, cell road surface, road, the effective precipitation in public leisure square are rationally collected, stored, It utilizes, alleviates the water of using in drought and water shortage season, it is significant.

Invention content

The main component of tobacco stalk is cellulose, hemicellulose, and modified tobacco stalk can adsorb the phosphoric acid in water Radical ion, phosphate anion are the key factors for causing water eutrophication, and bentonite is modifying agent and strong adsorbent, in water Heavy metal ion also has suction-operated, zeolite that can adsorb ammoniacal nitrogen, organic matter and heavy metal ion in water, also has ion The performance with acidproof heat-proof is exchanged, the pH value of water is adjusted, the heat on sponge brick surface can be passed, cement is porous sponge of catchmenting Brick increases mechanical strength and cementation, and the resin fibre of polyvinyl alcohol high water absorption is strong water absorbent, using dilatant slurry, reduces The density of slurries, a face of the manufactured porous sponge brick that catchments are in dovetail channel-shaped, the moisture of porous sponge brick absorption of catchmenting into Enter dovetail groove, is flowed into collector pipe again by the effect of gravity, collector pipe links together the porous sponge brick that catchments, and rainwater catchment arrives In collecting-tank.

Its technical solution is：It shines and inhales the method that phosphorous tobacco stalk squeezes out the porous sponge brick that catchments of particle preparation, first Step, the dispensing of the porous sponge brick that catchments：It is 250~450 μm of modified tobacco stalks extrusions by 15~20wt% of cement, grain size 45~65wt% of grain, 5~15wt% of sodium metasilicate of modulus 3.2~3.5, grain size are 100~200 μm of 3~5wt% of calcium oxide, ceramics Zeolite 15~30wt% samplings of 3~10wt% of fiber, 0.5~5.0wt% of high hydroscopic resin fiber and 100~200 μm of grain size, with The sum of weight percent of upper each component is 100%；

The preparation of second step, the porous sponge brick expansion water suction slurries that catchment：It samples by the weight percent of the first step, first will Grain size is that 250~450 μm of modified tobacco stalks extrusion particles are put into feed bin, is sent into distributing device by elevator, distributing device will Modified tobacco stalk squeezes out particle and is evenly distributed on governing belt balance, and spray thrower is uniform by the sodium metasilicate of modulus 3.2~3.5 It is sprayed at the outer surface that modified tobacco stalk squeezes out particle, enters inside spin drum agitation device, sodium metasilicate with governing belt balance It is inorganic bond, is hydrophilic, cohesive force is strong, intensity is higher, acid resistance, heat-resist, and hydrophilicity does not influence to bond Property, mixture is 15~20wt% of cement, grain size be 250~450 μm of tobacco stalks squeeze out 45~65wt% of particle, modulus 3.2~ 3.5 5~15wt% of sodium metasilicate, grain size are 100~200 μm of 3~5wt% of calcium oxide, 3~10wt% of ceramic fibre, super absorbent resin 15~30wt% of zeolite of 100~200 μm of 0.5~5.0wt% of fat fiber and grain size, by mixture with 0.4~0.7 ratio of mud tune Slurry, ash are mixture, add the aluminium powder cream that mixture total weight is 0.2~1.5%, and hydration reaction generates bubble, is formed porous The slurries of water suction are expanded, reduce the weight of sponge brick, polyvinyl alcohol high hydroscopic resin fiber has extremely strong water imbibition, after water suction Sponge brick compression strength it is constant；

The preparation of third step, the porous sponge brick that catchments：Expansion water suction slurries prepared by second step are stirred evenly and pour into sea In the die trial of continuous brick press, by 1.2~2.0:1 volume ratio is suppressed, and ratio 1.2~2.0 is the volume before compacting, and ratio 1 is Pressed volume is dried, porous one face of sponge brick of catchmenting is equipped with multiple grooves, by the sun through striking off, suppressing, demould Energy solar panel and LED light emitting diodes are placed in groove, and the solar energy of absorption is converted to electric energy and stored by solar panel Come, LED light emitting diodes are shone by the effect contacting of external force, as lighting installation, using a variety of flexible colors, module In can also be implanted into different music, regularly updated by wireless network, when external force disappears, contact disconnect, LED light emitting diodes Extinguish, another face of the porous sponge brick that catchments is equipped with dovetail channel-shaped, and the porous moisture for catchmenting the absorption of sponge brick enters dovetail groove Interior, collector pipe is embedded in dovetail groove, and rainwater collects by the porous sponge brick that catchments, into dovetail groove, is acted on by gravity Collector pipe is flowed into again, and collector pipe links together the single porous sponge brick that catchments, and the rainwater that collector pipe collects enters collecting-tank In.

Modified tobacco stalk squeezes out the preparation of particle：200~400 μm of particles of grain size first are made in the crushing of tobacco stalk, Tobacco straw powder, dimethylformamide, epoxychloropropane and dimethylamine agueous solution are pressed 1~3 again:12.5~15:8~10:12~ 18 samplings are uniformly mixed, and are put into retort, are reacted 3~8 hours at 80~120 DEG C, clean, is dry, form modified tobacco Straw powder adds 100~200 μm of bentonites of grain size, the two 70~85wt% by weight percentage：15~35wt% sampling mixing Uniformly, the sum of weight percent of two kinds of components is 100%, mixture is prepared by the ratio of mud 0.1~0.3, mixture is to be modified Tobacco stalk particle powder and bentonite, ash is mixture, and mixture is put into screw mixer and stirs evenly, and enters back into extrusion It is granulated in comminutor, the modified tobacco stalk of 250~450 μm of grain size is made after dry and squeezes out spheric granules, tobacco stalk is wood Matter stalk, main component be cellulose, hemicellulose, lignin, modified tobacco stalk can adsorb the phosphate radical in water from Son, phosphate anion are the key factors for causing water eutrophication, and bentonite is modifying agent and strong adsorbent, to the huge sum of money in water Belonging to ion also has suction-operated, and material component is different, and modified chemical property is also different.

Zeolite can adsorb ammoniacal nitrogen, organic matter and heavy metal ion in water, also have ion exchange and acidproof heat-proof Performance, adjust the pH value of water, sponge brick surface can be thermally conducted in soil.

Calcium oxide hydration reaction generates a large amount of heat, and it is in as a form of gel to generate calcium hydroxide, is given birth to silica, aluminium oxide At calcium silicates, calcium oxide is activator, the activity of excited cement.

Ceramic fibre is hollow type, can increase the mechanical tenacity of sponge brick, moreover it is possible to so that sponge brick is formed and multiple intersect in length and breadth Micropore, micropore have stronger sound absorption function.

A rainwater part for accumulation is pooled to by collector pipe in collecting-tank by the porous sponge brick that catchments, and another part penetrates into Into soil, increase soil water content, in summer high-temperature season, the heat on surface can also be transmitted to by the porous sponge brick that catchments In soil, the temperature on sponge tile floor surface is reduced, the thermal capacity of water is big, and can absorb heat also can heat release.

The present invention has the following advantages.
