(54) СГУСТИТЕЛЬ БАРАБАННЫЙ(54) POV DRUMER
1one
Изобретение относитс к барабанным сгустител м, предназначенным дл сгущени волокнистых суспензий и может быть использовано в целлюлозно-бумажной промышленности.The invention relates to drum thickeners for thickening fiber suspensions and can be used in the pulp and paper industry.
Известен сгуститель барабанный, включающий корпус, перфорированные барабаны, устройство дл удалени сгущенной массы, и устройство дл дополнительного отжима отложившегос сло волокон на поверхности барабанов 1.A drum thickener is known, comprising a body, perforated drums, a device for removing thickened mass, and a device for further pressing the deposited layer of fibers on the surface of the drums 1.
Недостатком известного сгустител вл етс высока металлоемкость и большие габариты , обусловленные малой поверхностью фильтровани , отнесенной к занимаемой сгустителем производственной площади, и относительно низка концентраци сгущенной массы при подаче в сгуститель волокнистой суспензии с концентрацией , менее 3%.A disadvantage of the known thickener is the high metal consumption and large dimensions due to the small surface of the filter referred to the production area occupied by the thickener and the relatively low concentration of the thickened mass when the fiber suspension is fed to the thickener with a concentration of less than 3%.
Цель изобретени - повышение производительности барабанного сгустител и степени сгущени массы.The purpose of the invention is to increase the productivity of the drum thickener and the degree of thickening of the mass.
Это достигаетс тем, что между нижней частью корпуса и перфорированными барабанами установлены упруго соединенные между собой перфорированные перегородки, частично охватывающие барабаны и щарнирно прикрепленные к корпусу.This is achieved by the fact that between the lower part of the body and the perforated drums, perforated partitions, which are elastically interconnected, are installed, partially covering the drums and pivotally attached to the body.
На чертеже изображен барабанный сгуститель (поперечный разрез).The drawing shows a drum thickener (cross section).
Сгуститель состоит из корпуса 1, двух перфорированных барабанов 2, двух перфорированных перегородок 3 с рёбрами жесткости 4, соединенных с корпусом шарнирами 5, упругого элемента 6, гидро- (или пневмо-) цилиндра 7 с .т гами 8, соединенными с перфорированными перегородками, патрубка 9 дл отвода фильтрата , патрубков 10 дл подачи волокнистой суспензии в сгуститель, шаберов 11 и транспортера 12.The thickener consists of a body 1, two perforated drums 2, two perforated partitions 3 with stiffeners 4, connected to the case by hinges 5, an elastic element 6, hydro (or pneumatic) cylinder 7 s. 8 gami 8, connected to perforated partitions, pipe 9 for removal of the filtrate, pipe 10 for feeding the fiber suspension to the thickener, scrapers 11 and conveyor 12.
Сгуститель работает следующим образомThe thickener works as follows
Волокниста суспензи под давлением через патрубки 10 поступает в ванну сгустител . ПодThe fiber suspension under pressure through the nozzles 10 enters the thickener bath. Under
15 действием перепада давлени фильтрат проходит во внутрь барабанов и через перфорированные перегородки 3, а на поверхности барабанов 2 и перегородок 3 образуетс осадок из- волокна . При вращении барабанов отложившийс на15, by the pressure differential, the filtrate passes into the interior of the drums and through the perforated partitions 3, and a precipitate of fiber is formed on the surface of the drums 2 and partitions 3. During the rotation of the reels deposited on
2Q их поверхности осадок отжимаетс в зазоре между ними, снимаетс щаберами 11 и удал етс из сгустител транспортером 12. Образующийс осадок на перегородках 3 в зоне поступлени суспензии в сгуститель смываетс потоком сгущаемой массы, а на последующих участ25 ках отжимаетс в зазоре между перегородками2Q of their surface, the precipitate is pressed in the gap between them, removed by the scraper 11 and removed from the thickener by the conveyor 12. The formed precipitate on the partitions 3 in the zone of the suspension entering the thickener is washed off by the flow of the condensed mass, and in subsequent sections 25 is pressed in the gap between the partitions
