Description
траспортирукщим шнеком, а шахта - штуцером дл подачи сжатого воздуха и пнев матическим транспортирующим приспособлением , к которому присоединен штуцер дл отвода рчишенной крошки . Шахта снабжена штуиером дл подвода жидкости с сетчатой головкой. Ванна снабжена загрузошым шнеком и вьшолнена в нижней части воронкообраз , ной формы. На фиг. 1 представлено устройство о,бщий ВИД , на фиг. же.вдрйант;. Ванна 1 наполнена промзлвочной жидкостью и имеет наклонно установленное сетчатое дно (сетку) 2 таким образом, что простираетс от зоны подачи крошки до зоны ее выхода из устройства и пере. секает поверхность жидкости 3 под углом oj. . Параллельно сетке 2 расположен вращающийс вал 4, установленный с одной стороны в подшипнике 5, а с другой просоединен к электродвигателю 6. На валу 4 в зоне подачи расположены листовые лопасти 7, через кронштейны 8 св занные с валом. В зоне вьшадени наполшател в осадок вал 4 шнеком 9. Внутри подающего штуцера 1О предусмотрен загрузочный шнек 11, посредством которого наполнитель принудительно вводитс в жидкость. Шнек J.1 погружен внутрь ванны ао поверхности жиакости 3 н приводитс во вращение электромотором 12, размешенным внутри кожуха 13 подаюцей воронки 14. Ванна 1 снабжена дефлекто - рами 15 и затвором 16 и с;успендируемы посторонние примесы извлекаютс посредством выводного штуцера 17, расположен ного в зоне поверхности жидкости 3. Ванна 1 имеет в нижней части 18 воронкообразную форму и штуцер отвода шлама 19. Промывочна жидкость подаетс в ванну из сопел 20. Осадок из ванны выгружаетс через штуцер 21. Ванна снабжена приспособлением 22 дл изменени ее положени по высоте и разгрузочным устройством 23. Последнее состоит из вертикальной шахты 24, котора находитс непосредственно под штуцером 21 выпадени осадка. Шахта заполнена жидкостью до уровн 25, расположенного над перепускной кромкой 26, Внутри шахты 24 поддерживаетс направленное вверк течение жидкости, дл чего предусмотрен штуцер 27 подвода жидкости с сетчатой головкой 28. В шахте 24 предусмотрен штуцер 29 подачи воздуха, о-г которого байпасный трубопровод 30 может й гть направлен к штуцеру 27. Посредстззом воздуха уменьшаетс количесто о подаваамой к штуцеру 27 жидкости. В верхней части шахты 24 расположен горизонтальный загрузочный канал 31. Внутри шахты 24 установлен на валу 32 врашак шийс сетчатый барабан 33..Барабанрас-, положен так, что он лишь незначительно выступает над уровнем 25 жидкости и незначительно аходит в горизонтальный разгрузочный канал 31. Из барабана 33 жидкость отводитс через штуцер 34, откуда она в |сачестве оборотной жидкости может подаватьс к штуцеру 27. Ванна 1 соединена с разгрузочным устройством 23 посредством шарнира 35. Дл уменьшени строительной высоты устройства под сеткой 2 может 6ь1ть предусмотрен транспортирук ций шнек 36, направл ющий мелкие частицы к штуцеру 19 вьшадени осадка. Шнек 36 может приводитьс во врашение через передачу 37 от вала 4 шнека. Устройство работает следующим образом . Наполнитель через штуцер 10 поступает в ванну 1 в свободном падении на расположенное над жидкостью сетчатое дно (сетку) 2. Если свободного падени оказываетс недостаточно, то наполнитель принудительно посредством транспортирующего шнека 11 вводитс в жидкость ванны 1. Здесь наполнитель лопаст ми мешалки приводитс в турбулентное движение и медленно транспортируетс к точке пересечени сетчатого дна (сетки) 2 и верхнего уровн 3 жидкости. При этой обработке под уровнем жидкости прилипша к наполнителю гр зь разм гчаетс . В зависимости от степени загр знени наполнител продолжительность этого процесса может быть большей или меньшей. В зависимости от положени листовых лопастей 7 наполнитель более или менее медленно поступает к месту вьшадени в осадок . Дефлекторы 15 могут поддерживать этот процесс. Вводимые с наполнителем суспендируемьге посторонние частипы тормоз тс перед затвором 16 и извлекаютс в штуцер 17, расположенный в зоне поверхности жидкости. Далее наполнитель с разм гченной гр зью попадает в зону сетки 2, расположенной над поверхностью жидкости 3. Здесь наполнитель листовыми лопаст ми 7 приводитс в турбулентное движение и растираетс . В этой зоне разм гченна гр зь отдел етс от наполнител ,и потадает на i-сетку 2 или, если частицы 1-р зи меньше, чем отверсти сетки, в нижнюю час-гъ 18с отвод щим шлам штуцером 19. Затем еще не отпавш.ие от наполнител частйшл гр зи отбрасываютс в зоне шнека 9 промывочной жидкостью, котора разфызгиваетс на наполнитель из промьточньис сопел 20. Здесь от наполнител отксьшаютс все частицы гр зи а гр зь и наполнитель попадают Ь штуцер 21. Степень загр знени наполнител различна, поэтому обработка в каждом случае должна быть различной. При особенно сильно сцепившейс гр зи предпочтительно проводить процесс разм гчени дольше. Если наклон лопастей 7 и дифлекторов 15 недостаточен, то вс ванна может быть установлена на шарнире 35 и. посредством присоблени 22 положение ванны может быть изменено по высоте. При опускании ванны 1 уровень жидкости 3 повышаетс так, что зона разм гчений увеличиваетс . Наоборот, при подьеме ваны зона разм гчени уменьшаетс и тем самьп увеличиваютс остальные зоны обработки . Шнек 9 траспортирует очищаемы наполнитель прерывисто к шггуцеру 21. Мокрый наполнитель должен быть обезвожен и осушен. Этот послед кщий процесс может экономично ; проводитьс только в непрерывном потоке. Дл непрерьюного подвода наполнител к последукшим процессам к месту вьтадени наполнител в осадок подключена шахта 24, заполненна жидкостью. Вытекающа из сетчатой головки 2 8 жидкость направлена так, что очищаемый наполнитель удерживаетс на поверхности 25 и только т желые частицы гр зи могут падать вниз. Очищаемый наполнитель захвагидваетс вращающимс сетчатым барабаном 33, извлекаетс из жидкости и подаетс к разгрузочному штуцеру, к которому присоединено пнев .матическое транспортирующие устройство (не показано), ст гивающее очшценый на полнитель .a conveyor auger, and the shaft a choke for supplying compressed air and a pneumatic conveying device to which the choke is connected. The shaft is equipped with a fluid head with a mesh head. The tub is equipped with a loading screw and a funnel-shaped shape is provided at the bottom of the tub. FIG. 1 shows the device, OVERVIEW; FIG. same vdryant ;. The bath 1 is filled with the frost liquid and has a sloped mesh bottom (mesh) 2 in such a way that it extends from the feed area of the crumb to the zone of its exit from the device and the over. cuts the surface of the liquid 3 at an angle oj. . Parallel to the grid 2 there is a rotating shaft 4 mounted on one side in the bearing 5, and on the other connected to the electric motor 6. On the shaft 4 in the feed zone there are sheet blades 7 through the brackets 8 connected to the shaft. In the area of the filler in the deposit, the shaft 4 is screwed 9. A feed screw 11 is provided inside the feed inlet 1O, by means of which the filler is forced into the liquid. The screw J.1 is immersed inside a bath of a 3 n surface of fluidity. It is rotated by an electric motor 12 placed inside the casing 13 by a feeder of a funnel 14. Bath 1 is equipped with deflectors 15 and a shutter 16 and secures the removed impurities by removing the outlet 17, which is located in the surface area of the liquid 3. The bath 1 has a funnel shape in the lower part 18 and a sludge discharge fitting 19. The washing liquid is supplied to the bath from the nozzles 20. The sediment from the bath is discharged through the fitting 21. The bath is equipped with a device 22 to change its shape The height and discharge device 23. The latter consists of a vertical shaft 24, which is located directly below the sedimentation fitting 21. The shaft is filled with liquid up to level 25 located above the overflow edge 26. Inside the shaft 24 a directional flow of fluid is maintained, for which a liquid supply nipple 27 with a mesh head 28 is provided. In the mine 24 an air supply nipple 29 is provided, of which the bypass conduit 30 It may be directed to fitting 27. By means of air, the amount of fluid supplied to fitting 27 decreases. In the upper part of the mine 24 there is a horizontal loading channel 31. Inside the mine 24, Vrashak Shiys net drum 33 is mounted on shaft 32. The drum is designed so that it only slightly protrudes above the level of liquid 25 and slightly goes to the horizontal discharge channel 31. the drum 33 is discharged through the nozzle 34, from where it, as a circulating fluid, can be supplied to the nozzle 27. The bath 1 is connected to the discharge device 23 by means of a hinge 35. To reduce the construction height of the device under the net 2 can 6 There is provided a conveyor screw 36, which directs fine particles to the fitting 19 of the sediment. The auger 36 may be caused through transmission 37 of the auger shaft 4. The device works as follows. The filler through the nozzle 10 enters the bath 1 in a free fall on the mesh bottom (grid) 2 located above the liquid. 2. If there is not enough free fall, then the filler is forced by means of the transporting screw 11 into the bath liquid 1. Here the filler of the agitators is driven into turbulent motion and is slowly transported to the intersection point of the mesh bottom (mesh) 2 and the upper level 3 of the liquid. In this treatment, under the liquid level, the adhesion to the filler material is relieved. Depending on the degree of contamination of the filler, the duration of this process may be more or less. Depending on the position of the leaf blades 7, the filler more or less slowly comes to the place of the sedimentation. Deflectors 15 can support this process. The foreign parts introduced with the suspending agent are braked in front of the shutter 16 and removed to the choke 17 located in the surface area of the liquid. The filler with softened dirt then enters the zone of the grid 2 located above the surface of the liquid 3. Here the filler is driven by sheet blades 7 into a turbulent motion and is dispersed. In this zone, the softened dirt is separated from the filler, and it slips onto the i-grid 2 or, if the particles are 1-fold, less than the grid holes, in the lower half of the 18c with a sludge nipple 19. Then it will not disappear. From the filler, part of the dirt is discarded in the zone of the auger 9 with washing liquid, which is spread onto the filler from the supply nozzles 20. Here, from the filler, all particles of dirt are removed, and the filler and filler get into the nozzle 21. each case should be different. With particularly tightly adhering dirt, it is preferable to carry out the softening process longer. If the inclination of the blades 7 and the diffractors 15 is insufficient, then the entire bath can be mounted on the hinge 35 and. by means of the prisobleniya 22 the position of the bath can be changed in height. When the bath 1 is lowered, the level of liquid 3 rises so that the softening zone increases. On the contrary, when lifting the bath, the softening zone decreases and the rest of the treatment zones increase by that. The screw 9 transports the cleaned filler intermittently to the hopper 21. The wet filler must be dehydrated and drained. This latter process can be economical; carried out only in continuous flow. For the continuous supply of filler to the subsequent processes to the place of filler deposition, a shaft 24, filled with liquid, is connected to the sediment. The liquid flowing out of the mesh head 2-8 is directed so that the filler to be cleaned is held on the surface 25 and only heavy dirt particles can fall down. The filler to be cleaned is gripped by a rotating mesh drum 33, removed from the liquid and fed to a discharge nipple to which a pneumatic conveying device (not shown) is attached, which pulls on the filler.
