Description
Oblasť technikyTechnical field
Vynález sa týka zariadenia na výrobu čerpateľných makových hmôt na stavenisku, ktoré pozostáva z miešačky, za ktorou je zaradené závitovkové čerpadlo. Ako čerpateľné maltové hmoty prichádzajú do úvahy najmä náter pod obkladačky, ako aj omietková a murovacia malta.The invention relates to a plant for the production of pumpable poppy masses on a construction site, comprising a mixer followed by a screw pump. Suitable pumpable mortar materials are, in particular, paint under the wall tiles as well as plaster and masonry mortar.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Zariadenie uvedeného druhu je známe najmä z DE-OS 3 504 397. Je tam opísaná miešačka, ktorá obsahuje otáčavé miešacie ústrojenstvo, a do ktorej sa cez dávkovacie zariadenie privádza pracovná suchá malta, ako aj potrebné množstvo vody. Keď je miešací dej skončený, otvorí sa klapka na dne miešačky, takže hotová náplň vstupuje do plniaceho násypníka závitovkového čerpadla, umiestneného dolu. Na závitovkové čerpadlo je pripojené hadicové vedenie, vedúce na miesto použitia.A device of this kind is known in particular from DE-OS 3 504 397. A mixer is described which comprises a rotating mixing device and into which a working dry mortar as well as the necessary amount of water is fed via a metering device. When the mixing process is complete, the flap on the bottom of the mixer opens so that the finished charge enters the bottom feed hopper of the screw pump. A hose line leading to the place of use is connected to the screw pump.
V známom zariadení je potrebná maltová hmota pripravovaná len po dávkach. Zariadenie je ďalej upravené na plnenie suchou pracovnou maltou, výhodne zo sila. Plnenie suchou maltou, dodávanou v balíkoch, ako aj plnenie maltovými hmotami, dodávanými v pojazdných miešačkách v pohotovosti na spracovanie, je prinajmenšom zdĺhavé a je v praxi sotva používané. To isté platí pre zásobovanie piesku a spojiva, vyrábanými na stavenisku.In the known apparatus, a mortar composition is only required in batches. The device is further adapted to be filled with a dry working mortar, preferably silo. The filling with dry mortar supplied in the packages as well as the filling with the mortar materials supplied in the mobile mixers at the ready for processing is at least lengthy and hardly used in practice. The same applies to the supply of sand and binder produced on site.
Vynález vychádza preto z úlohy vytvoriť také zariadenie, spomínané v úvode, ktoré by dokázalo plynulé dodávať čerpateľné maltové hmoty a pritom bolo kompaktné a robustné.The object of the invention is therefore to provide such a device as mentioned at the outset which is capable of delivering pumpable mortar fluently and is compact and robust.
Podstata vynálezuSUMMARY OF THE INVENTION
Zariadenie podľa vynálezu sa vyznačuje tým, že súosovo so závitovkovým čerpadlom je upravená závitovková miešačka, ktorej miešacia závitovka je neotočne spojená s hriadeľom závitovkého čerpadla a je spoločne s ním poháňaná, že nad jednotkou, pozostávajúcou zo závitovkovej miešačky a zo závitovkového čerpadla a rovnobežne k nej je umiestnený závitovkový dopravník, pracujúci v opačnom zmysle než táto jednotka, a ktorého výstupný otvor je cez šachtu spojený so vstupným otvorom závitovkovej miešačky, že závitovkový dopravník má medzi svojím vstupným otvorom a svojím výstupným otvorom, otáčavo poháňané ústrojenstvo, ktoré pozostáva zo sledu dopravnej závitovky, dávkovacej závitovky a predzmiešavacej závitovky na spoločnom hriadeli, a že medzi dávkovaciu závitovku a predzmiešavaciu závitovku ústi rúrka na prívod vody.The device according to the invention is characterized in that a screw mixer is provided coaxially with the screw pump, the mixing screw being non-rotatably connected to and driven by the screw pump shaft above the unit consisting of the screw mixer and the screw pump and parallel to it. a screw conveyor operating in the opposite direction to the unit is disposed and the outlet of which is connected via a shaft to the inlet of the screw mixer, that the screw conveyor has a rotatably driven device consisting of a conveyor screw sequence between its inlet and its outlet. , a metering screw and a premixing screw on a common shaft, and that a water supply pipe opens between the metering screw and the premixing screw.
Zariadenie podľa vynálezu umožňuje dosiahnuť plynulý prísun čerpateľnej maltovej hmoty s vopred stanoveným pomerom vody a suchej malty, ak je postarané o to, aby na vstupnom otvore závitovkového dopravníka bola stále suchá malta, a aby cez rúrku na prívod vody bolo privádzané množstvo vody, zodpovedajúce množstvu suchej malty, privádzanému v časovej jednotke závitovkou. Suchá malta môže byť odoberaná buď zo staveniskového sila, umiestneného najlepšie nad zariadením, alebo z vriec, naplnených suchou maltou. V uvedenom druhom prípade sa odporúča pracovať so strojom na prerezávanie vriec. Najmä pri menších množstvách môže byť však vstupný otvor závitovkového dopravníka zásobovaný suchou maltou, vyrobenou na stavenisku z piesku a spojiva.The device according to the invention makes it possible to achieve a continuous supply of pumpable mortar with a predetermined ratio of water to dry mortar if it is ensured that the mortar is still dry at the inlet opening of the screw conveyor and that a water quantity corresponding to dry mortar fed in time unit by screw. The dry mortar can be taken either from a construction site silo, preferably located above the machine, or from bags filled with dry mortar. In the latter case, it is recommended to work with a bag pruning machine. However, especially in smaller quantities, the inlet opening of the screw conveyor can be supplied with dry mortar made on site with sand and binder.
Šachta, umiestnená medzi výstupným otvorom horného závitovkového dopravníka a vstupným otvorom miešacej závitovky plní súčasne funkciu nárazníkovej nádržky. Súosové usporiadanie závitovkového dopravníka nad jednotkou, tvorenou závitovkovým čerpadlom a zá10 vitovkovým miešačom, vedie k zvlášť kompaktnému stavebnému vytvoreniu zariadenia. Výhodné použitie súosovo rotujúcich dopravných a miešacích ústrojenstiev robí zariadenie robustným a zvlášť vhodným na drsnú prevádzku na stavenisku. Privádzanie časovo konštantného 15 množstva vody je možné veľmi ľahko zaistiť usporiadaním ventilu na redukciu tlaku v rúrke na prívod vody.The shaft, located between the outlet opening of the upper screw conveyor and the inlet opening of the mixing screw, simultaneously functions as a buffer tank. The coaxial arrangement of the screw conveyor above the screw pump and vortex mixer unit results in a particularly compact construction of the device. The advantageous use of coaxial rotating conveying and mixing devices makes the device robust and particularly suitable for rough site operation. The supply of a time constant amount of water can be very easily ensured by arranging a pressure reducing valve in the water supply pipe.
Vstupný otvor dopravnej závitovky v závitovkovom dopravníku sa výhodne vytvorí ako násypník. V jej hornej oblasti môže byť potom umiestnený signalizátor pl20 ného stavu, ktorého signál riadi napríklad výstup suchej malty zo sila na stavenisku alebo stroj na prerezávanie vriec.The inlet opening of the conveyor screw in the screw conveyor is preferably designed as a hopper. In its upper region, a full-state signaling device can then be placed, the signal of which, for example, controls the output of dry mortar from the silo on the construction site or the bag cutter.
Rovnako tak je účelné, aby na hornom okraji šachty bol medzi predzmiešavacou závitovkou a závitovkovou 25 miešačkou, pod ňou umiestnenou, upravený druhý signalizátor plného stavu. Jeho signál riadi potom pohon závitovkového dopravníka.It is also expedient for a second full status indicator to be provided at the upper edge of the shaft between the pre-mixing screw and the screw mixer 25 located below it. Its signal then controls the drive of the screw conveyor.
Použitie uvedeného zariadenia môže byť ešte univerzálnejšie, ak medzi dávkovacou závitovkou a predzmie30 šavacou závitovkou je upravený ďalší vstupný otvor, nad ktorým je druhý násypník. Cez tento druhý násypník možno plniť napríklad hotovú maltu pripravenú v pojazdných miešačkách, v tomto prípade sa však preruší prívod vody.The use of said device can be even more versatile if a further inlet opening is provided between the metering screw and the premix 30 of the screw screw, over which is a second hopper. For example, the finished mortar prepared in the mobile mixers can be filled via this second hopper, but in this case the water supply is interrupted.
Zariadenie podľa vynálezu je možné však tiež použiť na výrobu čerpateľných makových hmôt z piesku a spojiva na stavenisku. V tomto prípade sa prevádzka zariadenia uskutočňuje spolu s dávkovacím dopravným pásom, ktorý dopravuje piesok z jeho nádržky do druhého nä40 sypníka, zatiaľ čo spojivo, napríklad cement, sa pridáva cez prvý násypník. Účelne sa potom pracuje s dávkovacou závitovkou, ktorej dopravný výkon sa zníži podľa pomeru piesku k spojivu.However, the device according to the invention can also be used for the production of pumpable poppy paste from sand and binder on site. In this case, the operation of the device is carried out together with a metering conveyor belt that transports sand from its reservoir to the second hopper 40, while a binder, such as cement, is added through the first hopper. Conveniently, a metering screw is used, whose conveying capacity is reduced according to the sand to binder ratio.
Kompaktná konštrukcia zariadenia uľahčuje jeho transport, najmä keď je ako celok namontované na podvozku.The compact design of the device makes it easy to transport, especially when mounted on the chassis as a whole.
Zariadenie bude teraz opísané v súvislosti so zjednodušeným príkladom jeho uskutočnenia, znázorneným na výkrese.The device will now be described in connection with a simplified embodiment of the invention shown in the drawing.
Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS
Na obr. 1 je znázornené zariadenie na výrobu čerpa55 teľných makových hmôt na stavenisku.In FIG. 1 shows a plant for producing pumpable poppy matter at a construction site.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Zariadenie v podstate pozostáva z dvoch jednotiek, usporiadaných nad sebou na podvozku, tu symbolicky znázorneným kolesom 21. Prvá, spodná jednotka pozostáva zo závitovkovej miešačky 130, za ktorou nasleduje súosovo upravené závitovkové čerpadlo 14, na výstupnú 65 stranu ktorého je pripojená dopravná hadica 16. Závitovková miešačka 130 obsahuje miešaciu závitovku 13, ktorá pozostáva z jednotlivých, primerane šikmo postavených miešacích krídel na spoločnom hriadeli. Spoločný hriadeľ je tu neotočne spojený s neznázomeným hriadeľom známeho závitovkového čerpadla 14. Hriadeľ závitovkovej miešačky 130 je spojený s pohonom 15, pozostávajúcim z elektromotora a z redukčného prevodového ústrojenstva.The device essentially consists of two units arranged on top of each other on a bogie, represented by the wheel 21 shown here. The first, lower unit consists of a screw mixer 130, followed by a coaxially arranged screw pump 14, to the outlet 65 of which the transport hose 16 is connected. The screw mixer 130 comprises a mixing screw 13 which consists of individual, suitably inclined mixing wings on a common shaft. Here, the common shaft is non-rotatably connected to the shaft of the known screw pump 14. The shaft of the screw mixer 130 is connected to a drive 15 consisting of an electric motor and a reduction gear.
Druhá jednotka je upravená nad prvou jednotkou a rovnobežne s ňou. Druhá jednotka obsahuje závitovkový dopravník, označený ako celok vzťahovou značkou 9, vybavený priebežným hriadeľom, ktorý je spriahnutý s pohonom 10, pozostávajúcim z ďalšieho prevodu a ďalšieho elektromotora. Zatiaľ čo spodná, prvá jednotka v znázornenom príklade uskutočnenia dopravuje zľava doprava, horná, druhá jednotka dopravuje sprava doľava. Na spoločnom hriadeli je uložená najskôr dopravná závitovka 9a, ktorej vstupný otvor, upravený v rúrkovitej skrini, prebieha prakticky po celej dĺžke dopravnej závitovky a pozostáva z vypúšťacieho prierezu násypníka 3. Za dopravnou závitovkou 3a nasleduje dávkovacia závitovka 9b. Konštrukcia a funkcia dávkovacej závitovky sú odborníkom známe a nie je preto potrebné ich bližšie vysvetľovať. Na dávkovaciu závitovku 9b nadväzuje predzmiešavacia závitovka 9c, ktorá v znázornenom príklade pozostáva z jednotlivých, primerane šikmo postavených miešacích krídel, ktoré sú neotočne spojené so spoločným hriadeľom.The second unit is arranged above and parallel to the first unit. The second unit comprises a screw conveyor, denoted as a whole by the reference numeral 9, provided with a continuous shaft which is coupled to a drive 10 consisting of a further transmission and a further electric motor. While the lower, first unit in the embodiment shown transports from left to right, the upper, second unit transports from right to left. First of all, a conveyor screw 9a is disposed on the common shaft, the inlet opening of which is arranged in the tubular housing extends substantially along the length of the conveyor screw and consists of a discharge cross section of the hopper 3. The conveyor screw 3a is followed by a dosing screw 9b. The design and function of the metering screw are known to those skilled in the art and therefore do not need to be explained in detail. The metering screw 9b is followed by a pre-mixing screw 9c, which in the example shown consists of individual, suitably inclined mixing wings, which are non-rotatably connected to a common shaft.
Na výstupe dávkovacej závitovky 9b je v rúrkovitej skrini závitovkového dopravníka 9 ďalší vstupný otvor, zodpovedajúci výstupnému prierezu druhého násypníkaAt the outlet of the metering screw 9b there is another inlet opening in the tubular housing of the screw conveyor 9 corresponding to the outlet cross section of the second hopper
5. V pripojení na tento druhý vstupný otvor ústi do závitovkového dopravníka 9 rúrka 8 na prívod vody. Rúrka 8 na prívod vody je cez priezor 17 a redukčný ventil tlaku 18 spojená s vodnou prípojkou 20, napríklad hadicou s vodou.5. In connection with this second inlet opening, a water supply pipe 8 enters the screw conveyor 9. The water supply tube 8 is connected to a water connection 20, for example a water hose, via a sight glass 17 and a pressure reducing valve 18.
V koncovej oblasti predzmiešavacej závitovky 9c má skriňa závitovkového dopravníka 9 výstupný otvor, ktorý je cez šachtu 11 priamo spojený so vstupným otvorom závitovkovej miešačky 130 spodnej jednotky. Táto šachta plní zároveň funkciu prechodnej alebo zásobnej nádržky.In the end region of the premix screw 9c, the screw conveyor housing 9 has an outlet opening, which is directly connected to the inlet opening of the screw mixer 130 of the lower unit via a shaft 11. This shaft also serves as a temporary or storage tank.
Ak sa teraz plniaci násypník 3 naplní prevádzkovou suchou maltou, napríklad zo staveniskového sila 1, ktoré je vybavené vibrátorom 2, potom sa pri zapojení pohonu 10 a pri otvorení ventilu 18 na redukciu tlaku privádza prevádzková malta cez dopravnú závitovku 9a a dávkovaciu závitovku 9b v dávkovacom množstve do toho priestoru závitovkového dopravníka 9, ktorý obsahuje predzmiešavaciu závitovku 9. Tam sa plynulé privádza z rúrky 8 tiež dávkované množstvo vody. Predzmiešavacia maltová hmota sa cez šachtu 11 dostane do závitovkovej miešačky 130, kde sa pri zapojení pohonu 15 definitívne premieša a privádza do závitovkového čerpadla 14, ktoré maltovú hmotu plynulé čerpá cez dopravnú hadicu 16 k miestu jej upotrebenia.If the filling hopper 3 is now filled with operational dry mortar, for example from a construction silo 1 equipped with a vibrator 2, then when the actuator 10 is connected and the pressure reducing valve 18 is opened, the working mortar is fed through the conveying screw 9a and the dosing screw 9b in a quantity of water is also fed continuously from the tube 8 into the screw conveyor 9, which contains the premixing screw 9. The amount of water is also continuously fed from the tube. The premixing mortar mass passes through the shaft 11 into the screw mixer 130 where it is finally mixed when the drive 15 is connected and fed to the screw pump 14, which continuously pumps the mortar mass through the transport hose 16 to the point of use.
Násypník 13 je vybavený signalizátorom 4 plného stavu, ktorý sa stará o to, aby násypník bol trvalé dostatočne naplnený suchou maltou. S tým cieľom môže signalizátor 4 plného stavu vyvolať napríklad zapojenie vibrátora 2 staveniskového sila 1, keď nie je dosiahnutý predpísaný plný stav.The hopper 13 is provided with a full condition indicator 4 which ensures that the hopper is permanently filled with dry mortar. To this end, the full-state signaling device 4 can cause, for example, the engagement of a vibrator 2 of the construction site force 1 when the prescribed full-state is not reached.
Tiež šachta 11 je vo svojej hornej oblasti vybavená signalizátorom 12 plného stavu. Ten zaberá do riadenia pohonu 10 a ventilu 18 na redukciu tlaku, ktorý zároveň má funkciu uzatváracieho ventilu. Ak nie je dosiahnutý predpísaný plný stav, uvedie sa do činnosti pohon 10 a otvorí sa redukčný ventil 18. Ak je predpísaný plný stav v šachte 11 prekročený, zastaví sa naopak pohon 10 a uzavrie sa redukčný ventil 18. Spojovacie vedenia, na to potrebné, s rozvodovou skriňou 19, vykonávajúce celkové riadenie opísaného zariadenia, nie sú pre jednoduchosť bližšie opísané.Also, the shaft 11 is provided in its upper region with a full status indicator 12. This engages in the control of the actuator 10 and the pressure reducing valve 18, which also functions as a shut-off valve. If the prescribed full state is not reached, the actuator 10 is actuated and the pressure regulator 18 is opened. If the prescribed full condition in the shaft 11 is exceeded, the actuator 10 is stopped and the pressure regulator 18 is closed. with the control box 19 performing the overall control of the described apparatus are not described for the sake of simplicity.
Ako už bolo uvedené, je možné pomocou zariadenia podľa vynálezu okrem iného tiež vyrábať čerpateľnú maltovú hmotu priamo z piesku a spojiva. V tomto prípade sa spojivo zavedie do násypníka 3, zatiaľ čo piesok do násypníka 5. Dávkovacie množstvo spojiva sa vykonáva dávkovacou závitovkou 4b. Na dávkovanie piesku sa použije dávkovací pás 6 známeho druhu, ktorý začína pod nádržkou 7 s pieskom a po šikmom vzostupe končí nad násypníkom 5. Dávkovanie množstva vody sa vykonáva tak, ako už bolo opísané. Týmto spôsobom je možné veľmi jednoducho vyrábať čerpateľné maltové hmoty, ktoré sú prispôsobené danému účelu použitia, sú homogénne premiešané a majú práve potrebnú konštitúciu, a to napríklad aj z koncentrátu, t.j. vopred zmiešaného spojiva s prísadami, za pridania piesku pomocou dávkovacieho dopravného pásu, a to podľa žiadaného alebo potrebného zmiešavacieho pomeru.As already mentioned, it is also possible to produce pumpable mortar directly from sand and binder by means of the device according to the invention. In this case, the binder is introduced into the hopper 3, while the sand is introduced into the hopper 5. The dosing amount of the binder is performed by the dosing screw 4b. To dispense sand, a dispensing belt 6 of known type is used, which begins below the sand reservoir 7 and, after an inclined rise, ends above the hopper 5. The amount of water is dispensed as described above. In this way, it is very easy to produce pumpable mortar compositions which are adapted to the intended use, are homogeneously mixed and have the necessary constitution, for example also from a concentrate, i. pre-mixed binder with additives, with the addition of sand by means of a metering conveyor belt, according to the desired or necessary mixing ratio.
