Keksinnön kohteena on suotonauhapuristin, apukemikaali11a kunnostettujen ja lietteeksi paksunnettujen suspensioiden tai sentapaisten kuivaamista varten, jossa liete tulokaukalosta esierotusrummun välityksellä syötetään päättömälle ylä-suotonauhalle, jonka alkuosa muodostaa gravitaatiosuodatusvyöhykkeen, ja esikuivattu liete sen-jälkeen kuljetetaan kääntötelan yli toiselle samanlaiselle nauhalle, ala-euotonauhalle, jonka jälkeen se nauhojen välissä jatkaa ensin vaakasuorassa suunnassa ja sitten vetorummun ympäri, josta liete edelleen nauhojen välissä kulkee puristustelojen ympäri, jotka liet-teeseen kohdistavat säädettävän puristus- ja leikkauspaineen, kunnes lietekakku poistuu ylemmän ja alemman lietekaapimen avulla.The invention relates to a filter belt press, auxiliary chemical 11a for drying reconstituted and slurry-thickened suspensions or the like, in which sludge from the inlet trough via a pre-separation drum is fed to an endless top filter belt. then between the strips it continues first in a horizontal direction and then around a traction drum, from which the slurry further passes between the strips around press rolls which apply an adjustable pressing and cutting pressure to the slurry until the slurry cake is discharged by the upper and lower sludge scrapers.
Tämäntapaiset suotonauhapuristimet ovat entuudestaan sinänsä tunnettuja. Käsillä olevan keksinnön tarkoituksena on aikaansaada kokoonsa nähden vielä tehokkaampi ja käyttövarmempi puristin. Tämä käy keksinnön mukaan mahdollisksi esierotusrummun ja vetorummun rakenteiden avulla. Keksinnönmukaieelle laitteelle onkin pääasiallisesti tunnusomaista se, että mainitun esierotusrummun muodostaa laattateräsrun-koinen ja lieriönmuotoisella kutisteviiralla päällystetty rumpu, joka syöttää flokatun lietteen tasaisena mattona ylä-suotonauhalle, ja että vetorummun muodostaa sisävaippa ja reijitetty ulkovaippa, joiden välissä on ohjauslevyt, jotka ohjaavat erotetun veden veto-rummun ulkosivuja pitkin alasuodosastiaan. Nämä kaksi rumpua täyden- 2 £0627 tävät toisiaan ja orat riippuvaisia toisistaan sikäli, että puolivalmiin lietekakun käsittely vetorummussa ei olisi tehokasta ilman esierotusrumpua, eikä esierotusrummusta tuleva liete olisi valmista eeuraavien puristustelojen käsittelyyn ilman keksinnön mukaista vetorumpua.Filter belt presses of this type are already known per se. The object of the present invention is to provide a press which is even more efficient and reliable in relation to its size. According to the invention, this is made possible by the structures of the pre-separation drum and the traction drum. The device according to the invention is therefore mainly characterized in that said pre-separation drum is formed by a plate steel frame drum coated with a cylindrical shrink wire, which feeds the flocculated slurry as a flat mat on the upper filter strip. along the outside of the drum into the bottom filtration vessel. The two drums complement each other and the spikes are interdependent in that the handling of the semi-finished slurry cake in the traction drum would not be efficient without the pre-separation drum and the slurry from the pre-separation drum would not be ready for handling the following press rolls without the traction drum according to the invention.
Keksintöä selostetaan seuraavassa lähemmin viittaamalla oheiseen, erään keksinnön suoritusmuodon esittävään piirustukseen.The invention will now be described in more detail with reference to the accompanying drawing, which shows an embodiment of the invention.
Runkoon 1 on kiinnitetty tulokaukalo 2, jonka leveys ja muoto vastaavat esierotusrumpua 3, jonka muodostaa päätylevyjen 4 kanssa samansuuntaiset tukirenkaat 5, joihin esim. hitsaamalla on kiinnitetty säteissuuntaiset viirankantolevyt 6. Rumpu 3 on päällystetty kutisteviiralla 7 ja laakeroitu ontolle akselille, jonka kautta huuhteluvesi pääsee vesiputkeen 8 ja sen alla olevaan suihkuputkeen 9, jossa on suuttimet kutisteviiran 7 mahdollista huuhtelua varten. Esierotusrumpu 3 syöttää lietteen tasaisesti ylä-suotonauhalle 10, joka tukitelojen 11 kannattamana ensin kulkee vaakasuorassa suunnassa, sitten ylä-taittotelan 12 yli vaakasuorassa suunnassa, veto-rummun 13 ympäri ja ala-taittotelan 14 yli, kiemurtelee puristus-telojen 15 välissä ja kiertää alempaa pääty-telaa 16, jossa se luovuttaa valmiin lietekakun alemman lietekaapimen avulla. Ylä-suoto-nauha 10 jatkaa telan 16 alapuolelta, kiertää tukitelojen 11 tukemana vetotelaa 13 ja palaa vaakasuoraan ylätasoon. Ala-suotonauha 17 kiertää ylempää päätytelaa 18, kulkee vaakasuorassa suunnassa ja vastaanottaa lietematon 19 ylä-taitto- eli kääntötelan 12 alapuolella, josta se jatkaa yhdessä yläsuotonauhan 10 kanssa, kiertää vetorumpua 13t ala-taittotelaa 14 ja puristusteloja 15, kunnes se ylemmän päätytelan 18 kohdalla luovuttaa lietekakun ja jatkaa ylöspäin. Suotonauhapuristimeen kuuluu lisäksi huuhtelusuuttimia 20 ja esierotusrummun 3 ja ylä-suotonauhan 10 ylimmän osan alla oleva ylä-suodosastia 21 sekä koko laitteen alla oleva alaeuodosastia 22. Lisäksi siihen kuuluu esierotusrummun 3 ja vetorummun 13 käyttö-koneisto ja portaaton nopeudensäätö 23.Attached to the body 1 is an inlet trough 2, the width and shape of which correspond to a pre-separation drum 3 formed by support rings 5 parallel to the end plates 4, to which radial wire carrier plates 6 are attached, e.g. by welding. 8 and a spray pipe 9 below it, with nozzles for possible rinsing of the shrink wire 7. The pre-separation drum 3 feeds the slurry evenly to the upper filter belt 10, which, supported by the support rollers 11, first passes horizontally, then horizontally over the upper folding roll 12, around the traction drum 13 and over the lower folding roll 14, twists between the compression rollers 15 and rotates the lower end -roll 16, where it delivers the finished sludge cake by means of a lower sludge scraper. The upper filter strip 10 extends below the roll 16, rotated by the support rollers 11, rotates the traction roller 13 and returns to the horizontal upper plane. The lower filter belt 17 rotates the upper end roll 18, runs horizontally and receives the slurry 19 below the upper folding roll 12, from where it continues together with the upper filter belt 10, rotates the traction drum 13t the lower folding roll 14 and the press rolls 15 until hand over the slurry cake and continue up. The filtrate belt press further comprises rinsing nozzles 20 and an upper filtration vessel 21 below the upper part of the pre-separation drum 3 and the upper filtration belt 10 and a lower filtration vessel 22 under the whole device.
Vetorummun 13 muodostaa sisävaippa 24 ja reijitetty ulkovaippa 25, joiden välissä on ohjauslevyt 26, jotka ovat vinossa asennossa rummun 13 akselin 27 suhteen, ja jotka ohjaavat erotetun veden rummun 13 ulkosivuja pitkin alasuodosastiaan 22. Rumpua 13 vahvistaa sen päätylaippaan 28 kiinnitetyt radiaaliset jäykistyslevyt 29.The traction drum 13 is formed by an inner jacket 24 and a perforated outer jacket 25 with guide plates 26 inclined with respect to the shaft 27 of the drum 13 and guiding the separated water along the outer sides of the drum 13 to the lower filter vessel 22. The drum 13 is reinforced by radial stiffening plates 29 attached to its end flange.
