HAKKEEN PUHDISTAJA - FLISRENGÖRARECHIP CLEANER - FLISRENGÖRARE

Tämän keksinnön kohteena on hakkeen puhdietaja, joka muodostuu laatikkomaisesta pääseulasta, jossa on seulatasot, joissa hakkeen seulonta ja esipuhdistus tapahtuu vaakatasoisen ympyrän muotoisen seulontaliikkeen ansiosta ja jonka pääseulan perässä on raskaan materiaalin rikastin, jossa raskas ainesosa rikastetaan ja erotetaan puhtaasta hakevirrasta.The present invention relates to a chip cleaner consisting of a box-shaped main screen with screen levels in which the chips are screened and pre-cleaned by a horizontal circular screening movement and a main screen is followed by a heavy material concentrator in which the heavy ingredient is enriched and separated from the pure chip stream.

Tämäntapaisissa tunnetuissa hakkeen puhdistajissa tapahtuu raskaan materiaalin rikastaminen täry- ja ilmapuhalluksen tai veden avulla. Keksinnön tarkoituksena on aikaansaada uudentyyppinen hakkeen puhdistaja, jossa ei tarvita paljon energiaa vaativaa ilmapuhallusta ja vältetään samalla myös vesipesun epäkohdat, kuten hakkeen kosteuden nousu ja veden puhdistus.In known chip cleaners of this type, the enrichment of heavy material takes place by means of vibration and air blowing or water. The object of the invention is to provide a new type of wood chip cleaner which does not require air-intensive air blowing and at the same time also avoids the disadvantages of water washing, such as an increase in the moisture content of the wood chips and water purification.

Keksinnön mukaiselle puhdistajalle on tunnusomaista se, että raskaan materiaalin rikastin on pääseulan mukana lähes vaakatasossa liikkuva taso, jossa on vinottaisia listoja ja pääasiassa poikittainen kynnys ja jonka toisessa takanurkassa on raskaan materiaalin erotusaukko ja että puhdas hakevirta on järjestetty kulkemaan kynnyksen yli hakeseulan poistoaukkoon. Keksinnön avulla saadaan hakkeen seassa oleva raskas materiaali näinollen erittäin tehokkaasti pienellä energialla rikastetuksi ja poistetuksi puhtaasta hakevirrasta. Keksinnön mukaiselle puhdistajalle on lisäksi tunnusomaista se, että rikastusvaiku-tuksen lisäämiseksi on rikastimen vaakatasossa tapahtuvaan pyörintäliikkeeseen lisätty pystysuora täryliike täryttimen avulla.The cleaner according to the invention is characterized in that the heavy material concentrator is an almost horizontally moving plane with the main screen, with oblique strips and a substantially transverse threshold, with a heavy material separation opening in one rear corner and a clean chip stream passing through the screen. The invention thus makes it possible to enrich and remove the heavy material among the chips very efficiently with low energy from a clean chip stream. The purifier according to the invention is further characterized in that, in order to increase the enrichment effect, a vertical vibratory movement is added to the horizontal rotational movement of the concentrator by means of a vibrator.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheiseen piirustukseen, jossaThe invention will now be described by way of example with reference to the accompanying drawing, in which

Hakkeen puhdistaja muodostuu laatikkomaisesta pääseulasta 1, jossa on seulatasot 2, 3, jossa hakkeen karkeaseulonta tapahtuu vaakatasoisen ympyrän muotoisen seulontaliikkeen ansiosta. Pää-seulan perässä on raskaan materiaalin rikastin 4, jossa raskas ainesosa rikastetaan ja erotetaan puhtaasta hakevirrasta. Raskaan materiaalin rikastin 4 on pääseulan mukana lähes vaakatasossa liikkuva taso , jonka toiseen takakulmaan on järjestetty raskaan materiaalin erotusaukko 7 ja johon tasoon on ennen poikittaista kynnystä 8 järjestetty listat 6 vinosti siten, että ne pyrkivät ohjaamaan raskaan materiaalin erotusaukkoon 7, kun taas puhdas hakemateriaali kulkeutuu kynnyksen yli hakeseulan poistoaukkoon 9.The chip cleaner consists of a box-shaped main screen 1 with screen levels 2, 3, in which the coarse screening of the chips takes place due to a horizontal circular screening movement. The main screen is followed by a heavy material concentrator 4, where the heavy component is enriched and separated from the pure chip stream. The heavy material concentrator 4 is a plane moving almost horizontally with the main screen, in the second rear corner of which a heavy material separation opening 7 is arranged and in which plane the slats 6 are arranged obliquely before the transverse threshold 8 so as to guide the heavy material separation opening 7. over the chip screen outlet 9.

Kun pääseulasta 1 rikastimeen 4 tuleva hake joutuu sekä vaaka-tasoiseen seulonta 1iikkeeseen ja vielä listojen 6 ansiosta täryliikkeeseen, rikastuu raskas materiaali hyvin tehokkaasti hakevirrasta. Raskas materiaali pysähtyy kynnykseen 8 ja ohjautuu vinottaisten listojen 6 avulla erotusaukkoon 7. Puhdas hakevirta kulkee kynnyksen 8 yli ja siitä edelleen hakeseulan poistoaukkoon 9.When the chips coming from the main screen 1 to the concentrator 4 are subjected to both the horizontal screening movement and, thanks to the strips 6, the vibrating movement, the heavy material is enriched very efficiently from the chip stream. The heavy material stops at the threshold 8 and is directed by means of the oblique strips 6 to the separation opening 7. A clean chip stream passes over the threshold 8 and from there on to the chip screen outlet 9.
