Oblasť technikyTechnical field
Vynález sa týka spôsobu výroby suspenziou zvlášť Jemný cement/zvlášť Jemné pojlvo a príslušného výrobného zariadenia.The invention relates to a process for the production of a slurry of particularly fine cement / particularly fine binder and a corresponding production apparatus.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Systémy zvlášť Jemný cement/zvlášť Jemné pojlvo sa s narastajúcou mierou používajú v príprave betónu a v geotechnlke. Pritom slúžia cementové suspenzie z týchto systémov zvlášť Jemný cement/zvlášť Jemné pojlvo na vyplňovanie trhlín v betóne, medzier a puklín v skalách a pórovitých dutín vo zvetrávacích horninách.Systems in particular Fine cement / in particular Fine binders are increasingly used in concrete preparation and geotechnical engineering. In this case, cementitious suspensions from these systems serve in particular Fine cement / particularly Fine binder for filling cracks in concrete, gaps and cracks in rocks and porous cavities in weathering rocks.
Zvlášť Jemné cementy sú veľmi Jemnozrnné hydraulické pojlvá s vždy veľmi úzkou granulometriou a s obmedzením obsahu najväčších zŕn. Vlastnosti a použitie zvlášť Jemných cementov Je normované, napríklad v predbežnej norme Merkblatt fúr Elnpressarbelten mlt Feinstbindemltteln in Lockergestelnen (Bautechnlk 70 zošit Θ, Ernst & Sohn, str. 550 až 580 (1993) a vParticularly fine cements are very fine-grained hydraulic binders with always very narrow granulometry and limiting the largest grain content. Properties and use of particularly fine cements It is standardized, for example, in the pre-standard Merkblatt für Elnpressarbelten mlt Feinstbindemltteln in Lockergestelnen (Bautechnlk 70 workbook, Ernst & Sohn, pp. 550-580 (1993)) and in
ZTS-RISS 93, Verkehrblatt-Dokument B 5837, Verkehrsblattverlag).ZTS-RISS 93, Verkehrblatt-Document B 5837, Verkehrsblattverlag).
Názvoslovie v obidvoch známych normách nie je Jednotné . V Merkblatt Je používané označenie zvlášť Jemné pojlvá a v ZTS-RISS Je použitý pojem zvlášťThe nomenclature is not uniform in both known standards. In Merkblatt, the term Separate Fine is used and in ZTS-RISS the term Separate is used
Jemný cement. Americká literatúra hovorí o mikroskopicky Jemných portlandských cementoch (US-PS 5 108 425). V nasledujúcom texte je použitý hlavne pojem zvlášť Jemný cement, do Je označenie používané v príslušnej odbornej literatúre (Eeton 1/94, str. 18 až 16, Felsbau 11, ô. 6, zvláštne vydanie(1993), Bauingenieur 67, str. 499 až 504 (1998;).Fine cement. American literature mentions microscopically fine Portland cements (US-PS 5,108,425). In particular, the term particularly fine cement is used in the following text. It is used in the relevant literature (Eeton 1/94, pp. 18-16, Felsbau 11, No. 6, special edition (1993), Bauingenieur 67, p. 499). to 504 (1998;).
Podlá štandardizačných predpisov má pochádzať zvlášť Jemný cement na výrobu cementových suspenzií z viac ako 90% sitom s veľkosťou ôk 16gm (0,016mm) a zá sa vyrábať s vhodnými prísadami a prostriedkami. Pojmy súčastí prísad a prisudzovaných prostriedkov a Ich popis sú definované v Zement-Merkblatt č. B 3, BBD/EA 1.93/80.According to standardization regulations, in particular Fine cement for the production of cement suspensions should be made of more than 90% sieve with a mesh size of 16gm (0.016mm) and be produced with suitable additives and agents. The terms of the ingredients and adjuvants and the description thereof are defined in Zement-Merkblatt no. B 3, BBD / EA 1.93/80.
Zvláštna vhodnosť systémov zvlšť Jemný cement·/ /zvlášť Jemné poJ1vo pre uvedené aplikácie spočíva vo vysokej jemností pri súčasnom obmedzení najväčších zŕn suchých pojív. Smerodatné pre vhodnosť systémov zvlášť Jemný cement/zvlášť Jemné pojlvo Je nadto rozdelenie zŕn pojlva v suspenzií. Pri nedostatočnej disperzii zvlášť Jemného cementu vo vode môžu vznikať, prípadne zostávať aglomeráty, ktoré vylúčia napríklad lnjektovanle suspenzie zvlášť jemného cementu do najjemnejších trhliniek v betóne.The particular suitability of the specialty cement systems Fine Cement / / / Particularly fine coating for the above applications consists in high fineness while limiting the largest grains of dry binders. Determination of the suitability of the systems in particular Fine cement / in particular Fine binder There is moreover the distribution of binder grains in suspension. In the case of insufficient dispersion of particularly fine cement in water, agglomerates may arise or remain, which, for example, eliminate the suspensions of particularly fine cement into the finest cracks in the concrete.
Na nutnosť dostatočnej disperzie systémov zvlášť Jemný cement/zvlášť Jemné pojlvo pri výrobe suspenzií sa v príslušných predpisoch (ZTV-RISS,Merkblatt Felnstblndemlttel) výslovne poukazuje. Podľa ustanovenia uvedeného štandardu Je potreba na dosiahnutie optimálnej disperzie zvlášť Jemných pojív používať výhradne turbo-mlesióe alebo Iné mixéry s vysokou Intenzitou, pretože obzvlášť na techniku miesenia Je potreba klásť vyššie požiadavky. Ako vhodné zariadenia sú výslovne menované: turbo-miesiôe, odstredivé čerpadlá, vírivé čerpadlá.The need for sufficient dispersion of the systems in particular Fine cement / particularly Fine binder in the manufacture of suspensions is explicitly mentioned in the relevant regulations (ZTV-RISS, Merkblatt Felnstblndemlttel). Pursuant to the provision of the said standard, it is necessary to use only turbo-milling or other high-intensity mixers in order to obtain an optimum dispersion of particularly fine binders, since, in particular, the mixing technique requires higher requirements. Suitable devices are explicitly named: turbo-miesiôe, centrifugal pumps, vortex pumps.
Z publikácie Wiley-Interscience Construction and Deslgn of Cement Groutlng Je známe použitie ciesiča založeného na Venturlho princípe, pri ktorom sa cement nasáva do vákua a hneď potoč sa znieši s vodným lúčom. Pritom sa ale uvádza, že nedochádza k dobrému premieseniu a regulácii pomeru voda:cement, pretože voda sa musí privádzať ako plynulý lúč. Okrem toho sa uvádza, že také mlesiôe nie sú vhodné pre husté zmesi.From the Wiley-Interscience Construction and Deslgn of Cement Groutlng, it is known to use a blend based on the Venturl principle, in which the cement is sucked into a vacuum and immediately mixed with a water jet. However, it is stated that there is no good mixing and regulation of the water: cement ratio, since the water must be supplied as a continuous beam. In addition, it is stated that such mosses are not suitable for thick mixtures.
Z patentového spisu číslo ΞΡ 0 498879 Je známe zariadenie na prípravu a lisovanie cementovej suspenzie, ktoré má prípravnú a lisovaciu oblasť. Prípravná oblasť a lisovacia oblasť sú spolu navzájom spojené spojovacím potrubím a majú vždy nádrž, obehové potrubie a čerpadlo, ktorými môže cementová suspenzia cirkulovať na prípravu, prípadne na lisovanie. V spise sa uvádza, že v obehovom potrubí prípravnej oblasti Je sito a okolo nádrží prúdi vždy chladiace médium. Sitom má byť zabránené zhlukovaniu, pretože Je suspenzia pretlačovaná sitom pomerne vysokým tlakom, pričom sa rozomelú zhluky, nachádzajúce sa v suspenzii.A device for the preparation and compression of a cement slurry having a preparation and compression zone is known from patent specification 0 498879. The preparation zone and the compression zone are connected to one another via a connecting line and each have a tank, a circulation line and a pump by means of which the cement slurry can be circulated for preparation or compression. The document states that there is a sieve in the circulation line of the preparation zone of the preparation area and that there is always a cooling medium flowing around the tanks. The sintering should be avoided since the suspension is forced through the sieve by a relatively high pressure, whilst the agglomerates present in the suspension are ground.

Zariadenie na výrobu suspenzií systému zvlášť Jemný cement/zvlášť Jemné pojlvo podlá vynálezu znázornené na obr. 1, pozostáva zo zásobníka 1 opatreného miešadlom £, ktorý môže byť naplnený vodou a poprípade prídavnými prostriedkami alebo prídavnými látkami obvyklými pre systém zvlášť Jemný cement/zvlášť Jemné pojlvo. Dopravné potrubia 7a a 7k vedú od zásobníka 1 k čerpadlu £ a ďalej k mleslču £ pracujúcom na Venturiho princípe, ako Je napríklad vodná výveva, ktorý Je opatrený nádržou £, z ktorej sa pridáva systém zvlášť Jemný cement/zvlášť Jemne poJ1vo prípadne sa pridávajú rovnako Jemné suché zmesi. Podtlakom, vznikajúcim v mlesiól 5., sa nasáva systém zvlášť Jemný cement/zvlášť Jemné pojivo prípadne rovnako Jemná suchá zmes do vody, pretekajúcou miesičom 3, za vzniku suspenzie podobnej zmesi a dopravuje sa dopravným potrubím 7c opäť do zásobníka 1. Suspenzia sa môže teraz čerpadlom £ zo zásobníka 1 znova najmenej raz prečerpať do mleslča £, zmleslť sa s ďalším systémom zvlášť jemný cement/zvlášť jemné pojivo nato sa znova prečerpá späť do zásobníka 1 pričom sa postup aj niekoľkokrát opakuje, až sa ustanoví požadovaný pomer vody k cementu a prídavné prostriedky sa v suspenzii optimálne rozdelia a dlspergujú.Apparatus for producing system suspensions particularly Fine cement / particularly Fine binder according to the invention shown in FIG. 1, consists of a container 1 equipped with a stirrer 6, which can be filled with water and, if necessary, with the auxiliaries or additives customary for a particularly fine cement / particularly fine binder system. The conveying ducts 7a and 7k lead from the container 1 to the pump 6 and further to a ventilator 5 operating on the Venturi principle, such as a water pump equipped with a tank 6 from which the system is added extra fine cement / extra fine or possibly added as well. Fine dry mixtures. The vacuum generated in the molesol 5 sucks the system separately Fine cement / particularly Fine binder or even Fine dry mixture into the water flowing through the mixer 3 to form a suspension similar to the mixture and transported via conveying line 7c back to the container 1. The suspension can now pumped from tank 1 at least once to pusher 5, grind with another system extra fine cement / extra fine binder then pumped back into tank 1, repeating the process several times until the desired water to cement ratio and additional the compositions are optimally distributed and dispersed in the suspension.
Na dosiahnutie optimálnych vytvrdzovacích podmienok takto vyrobených suspenzií systému zvlášť Jemný cement/zvlášť Jemné pojivo napríklad pri vyplňovaní trhlín alebo medzier a puklín v skalách, Je možno zásobník 1 pri výhodnom realizovaní spôsobu podľa vynálezu chladiť alebo zahrievať v závislosti na vonkajšej teplote chladiacim alebo vykurovacím zariadením, takže suspenziu systému zvlášť Jemný cement/zvlášť Jemné pojivo je možné nastaviť na presné optimálne teplotné rozmedzie.In order to achieve optimum curing conditions of the system suspensions thus produced, particularly fine cement / particularly fine binder, for example when filling cracks or gaps and cracks in rocks. In a preferred embodiment of the method according to the invention, the container 1 can be cooled or heated depending on the external temperature by a cooling or heating device. so that the system suspension particularly fine cement / particularly fine binder can be adjusted to the exact optimal temperature range.
Najmenej Jedným alebo niekoľkonásobným preháňaním suspenzie obehom Je možné dopredu optimálne dlspergovať suché práškovíté prísady v systéme zvlášť jemný cement/zvlášť Jemné pojivo, takže Je nožná redukcia použitých množstiev prídavných prostriedkov.By at least one or more cycles of the suspension through the circulation, it is possible to optimally pre-disperse the dry powdery ingredients in a particularly fine cement / particularly fine binder system in advance, so that there is a foot reduction of the amounts of additives used.
Oddeleným prívodom vody, prípadne prídavkých látok a prídavných prostriedkov do zásobníka 1 a systému zvlášť jemný cement/zvlášť Jemné pojlvo do miesiča £ a rýchlym zdesením zložiek v ciesiči £ sa zabráni zhlukovanlu suspenzie, pričom najmä aplikácia miesiča ä, pracujúceho na Venturlho princípe, ako Je vodná výveva, sa zabraňuje v porovnaní s mechanickými nízkootáčkovými alebo vysokooiáčkovými miesičmi privádzaniu do miesiaceho systému prídavného tepla, vznikajúceho trením, a zmes nie Je nijako podrobovaná zvyšovaniu teploty prevádzkou čerpadla, pretože blok motora Je od dopravného agregátu čerpadla oddelený. Tak Je umožnená príprava suspenzie systému zvlášť Jemný cement/zvlášť Jemné pojlvo pri ďaleko stálejšej teplote.Separate supply of water and / or additives and additives to the container 1 and the extra fine cement / particularly fine binder system to the mixer 6 and rapid scaring of the components in the mixer 4 prevent agglomeration of the suspension, in particular application of the mixer 6 working on the Venturl principle. the water pump is prevented from being fed to the stirrer of the additional heat generated by friction compared to the mechanical low-speed or high-speed mixers, and the mixture is not subject to any increase in temperature by the pump operation since the motor block is separated from the pump transport unit. Thus it is possible to prepare a system suspension of particularly fine cement / particularly fine binder at a much more stable temperature.
