Abstract
Description
20 25 30 508 704 Med en apparat enligt uppfinningen, som visas i bifogad ritning kan dessa halter förbättras avsevärt. Den förbätt- rar halten mycket redan i det första steget på den sk uppdelningen, som sedan förbättras ytterligare i följande steg. (flotationsapparater). 20 25 30 508 704 With an apparatus according to the invention, as shown in the attached drawing, these contents can be improved considerably. It improves the content considerably already in the first stage of the so-called separation, which is then further improved in the following stages. (flotation apparatus).
Apparatens funktion går ut på att den i längdriktningen har två liggande väggar som går nästan mot varandra. (spalt på 30 cm). Den väggen som koncentratet kommer att rinna pá, kommer att luta mer än den andra. Detta för att få upp skummet, som samlats under vägg 2, till vägg l och vidare uppåt till reningsprocessen.The function of the device is that it has two horizontal walls in the longitudinal direction that run almost towards each other. (gap of 30 cm). The wall that the concentrate will flow on will be tilted more than the other. This is to bring the foam, which has collected under wall 2, up to wall 1 and further upwards to the purification process.
Vägg 2 får hög lutning mot l därför behövs luftrör under vägg 2 som gör det möjligt att trycka eller blåsa upp luftbubblorna till spalten där reningen sker. Luftrören blåser bara i skummet (ej i pulpen) och för att hålla denna vägg ren från t ex trästickor som annars kan fastna.Wall 2 has a high slope towards l, therefore air pipes are needed under wall 2 to make it possible to push or inflate the air bubbles to the gap where the cleaning takes place. The air pipes only blow into the foam (not into the pulp) and to keep this wall clean from, for example, wooden sticks that could otherwise get stuck.
Spalten som skummet samlas i har en öppning av 30 cm.The gap in which the foam collects has an opening of 30 cm.
Skummet från vägg 2 går således över till vägg l, där reningen sker. Eftersom luftbubblorna följer de sneda väggarna så sker reningen där. Reningen av bubblorna sker med en vattenstråle 3 som slår mot en platta av hårt gummi eller keramik, som sedan vidgas och spolar rent skummet som finns mellan väggen l och väggen 4.The foam from wall 2 thus passes over to wall 1, where the cleaning takes place. Since the air bubbles follow the inclined walls, the cleaning takes place there. The cleaning of the bubbles is done with a water jet 3 that hits a plate of hard rubber or ceramic, which then expands and flushes clean the foam that is between wall 1 and wall 4.
Vattenstràlen (trycket kan varieras) har inte hårt tryck.The water jet (pressure can be varied) does not have strong pressure.
Väggen 4 har samma lutning som väggen l. Fyra stycken vattenrör används till varje apparat. Även Vattenstràlen 5 kan användas pà väggen 4 för ytterligare rening. Klenare dimension. När vattenrör användes så är risken för (ofta problem) igensättning av rören minimal. (ej att jämföra med vanliga vattendyser). Dimensionen på vattenrören kan variera efter storlek på apparat. Med detta förfarande behövs ej några vattendyser som har använts pà tidigare apparater. 10 15 20 25 30 3 508 704 Lutningen på vägg 4 är densamma som för vägg l för att det skall bli en spalt och att skummet lätt vandrar uppåt efter reningen. Den demonterbara väggen 6 är löstagbar pga att det skall vara möjligt att öppna apparaten vid t ex reparation av rotor eller rengöring. Under drift är apparaten nästan helt sluten, endast spalten är öppen.Wall 4 has the same slope as wall 1. Four water pipes are used for each device. Water jets 5 can also be used on wall 4 for further cleaning. Smaller dimensions. When water pipes are used, the risk of (often a problem) clogging of the pipes is minimal. (not to be compared with ordinary water nozzles). The dimensions of the water pipes can vary depending on the size of the device. With this method, no water nozzles are needed that have been used on previous devices. 10 15 20 25 30 3 508 704 The slope of wall 4 is the same as for wall 1 so that there is a gap and that the foam easily migrates upwards after cleaning. The removable wall 6 is removable because it should be possible to open the device for, for example, rotor repair or cleaning. During operation, the device is almost completely closed, only the gap is open.
Rotorn 7 gör att luften fördelas ut i apparaten och gör strömmar i pulpen som krävs för att den skall fungera och bilda skumbädd. Dimension på rotor varierar från apparat till apparat. (Olika storlek pà apparater). Luft- tillflödet 8 regleras med en ventil eller kran. Nivån pà pulpen 9 regleras med ribbor som kan borttagas eller ersättas med flera. Koncentratet som bildas rinner pà ovansidan av vägg 2 som är pàbyggd upptill för att koncen- tratet lättare skall rinna ner, som sedan samlas i en uppsamlare ll.The rotor 7 distributes the air in the device and creates currents in the pulp that are required for it to function and form a foam bed. The rotor dimensions vary from device to device. (Different sizes of devices). The air supply 8 is regulated with a valve or tap. The level of the pulp 9 is regulated with ribs that can be removed or replaced with several. The concentrate that is formed flows on the top of wall 2 that is built up at the top to make it easier for the concentrate to flow down, which is then collected in a collector ll.
Vattenstrálarna 3 fungerar inte bara som renande av skum- bädden, den gör dessutom så det blir en reaktion mellan olika mineralkorn så att de delar pà sig (när det gäller uppdelning av mineral). PH - surhetsgrad spelar också in. För att skilja flera mineraler från gràberg krävs ett annat PH. Vattenstràlen i apparaten måste sitta exakt i förhållande till vägg l. Röret som Vattenstràlen kommer ur görs därför steglös så att stràlen kan justeras upp eller ner. Åt sidan får den ej ändras. Röret monteras rakt mot vägg l.The water jets 3 not only function as a cleanser of the foam bed, they also cause a reaction between different mineral grains so that they split (when it comes to mineral separation). PH - acidity also plays a role. In order to separate several minerals from gravel, a different PH is required. The water jet in the device must be positioned exactly in relation to wall l. The pipe from which the water jet comes is therefore made stepless so that the jet can be adjusted up or down. On the other hand, it must not be changed. The pipe is mounted straight against wall l.
Reaktionen med vattnet gör så att bubblorna med koncen- tratet får en väldig fart uppåt.The reaction with the water causes the bubbles with the concentrate to gain enormous upward momentum.
