Abstract

For distributing loose fibres on a moving forming web (2) in dry forming of paper an air fluidized fibre material is fed to and recirculated in a pipe circuit comprising two parallel, straight screen pipes (12) extending over the forming web (2) and provided with interior, rotating needle cylinders (34) operating to both convey the material axially in the pipe and effect disintegration of the material as well as to add to the material flow a radial component promoting the fibre outlet through the walls of the screen pipes (12). These pipes (12) themselves are rotatably mounted and adjacent an upper outside area of each pipe (12) is arranged a stationary nozzle system (44) for blowing compressed air against the pipe to thereby successively clean the screen perforations for maintaining a high distributor capacity and enable relatively long fibres to be used in the production.

Система включает пористое полотно 1, непрерывно движущеес  по замк- нутой траектории, проход щей под распределительным блоком 2, выполненным в виде контейнера 3 с перфорированным участком вьтускной стенки , представл ющего собой элемент трубы 4 дл  прохождени  через него частиц или волокна материала, и имеющим направл ющее средство дл  направлени  в блок в воздушном потоке материала по траектории циркул ции над формующим полотном вдоль внут™ ренней поверхности участка выпускной стенки, всасывающее средство 5 расположенное под полотном дл  про- сасывани  через него воздуха дл  пе реноса выход щего из контейнера материала на полотно, и средство дл  обработки материала, содержащее цилиндр 6 со стержн ми 7, расположенными по винтовой линии, установленный с возможностью вращени  с Провод щие средства 8 расположены над формующим полотном с обоих концов контейнера 3 и св заны с концами элемента трубы дл  образовани  замкнутого конту- ра., Концы элемента трубы 4 опираютс  на подщипники 9 вращени , установленные в противоположных торцовых стенках 10 контейнера 3 Элемент трубы снабжен проход щей по касательной впускной трубой 11,, На концах элемента трубы 4 имеютс  неперфорированные втулки 12, взаимодействующие с подшипниками 9 и вход щие с уплотнеыи ем и с возможностью вращени  в про вод щие средства 8„ Примыкающие к од ному концу элемента трубы 4 втулки 12 соединены с приводом дл  вращени  элемента трубы - приводным ремнем 13, приводимым в действие шкивом двигател  4о В верхней стенке контейнера 3 выполнены сквозные прорези IS ширина которых может регулироватьс  пластинами 16 затвора.The system includes a porous web 1, continuously moving along a closed trajectory, passing under the distribution unit 2, made in the form of a container 3 with a perforated section of the outlet wall, which is an element of the pipe 4 for passing particles or fiber of the material through it, and having means for directing into the unit in the air flow of the material along the circulation path above the forming web along the inner surface of the outlet wall section, suction means 5 located under the webs air for suction of material exiting the container onto the web, and means for treating the material comprising a cylinder 6 with rods 7 arranged along a helical line rotatably mounted. Conductive means 8 are located above the forming the web at both ends of the container 3 and are connected to the ends of the pipe element to form a closed contour. The ends of the pipe element 4 are supported on rotating rods 9 mounted in opposite end walls 10 of the container 3 provided with a tangential inlet pipe 11 ,, At the ends of the element pipe 4 there are non-perforated sleeves 12, which interact with the bearings 9 and enter with sealing and rotatably into the conductive means 8 "adjacent to one end of the pipe element 4 bushings 12 are connected to a drive for rotating a pipe element — a driving belt 13 driven by a motor pulley 4o. In the upper wall of the container 3 there are through-slits IS whose width can be adjusted by the gate plates 16.

Над элементом трубы 4 установлено очистное средство 17„ Внутри элемента трубы расположен несущий элемент 18, снабженный воздущными насадками 19 о Над цилиндром .6 установлена экранирующа  пластина 20,A cleansing means 17 is installed above the pipe element 4. Inside the pipe element there is a bearing element 18 provided with air nozzles 19 o A shielding plate 20 is installed above the cylinder .6,

Система работает следующим обра- зом„The system works as follows:

Воздушный поток дл  насьщени  волокнистого материала подаетс  от воздуходувки (не показана) через впускную трубу 11, в результате чего создаетс  поток частиц материала, циркулирующий в элементе трубы 4 и провод щих средствах 8„ Отдельные волокна выпускаютс  из этого потока наружу через перфорированный участок выпускной стенки вместе с избыточным воздухом , подаваемым через впускную трубу 1 1 , Воздух принудительно направл етс  вниз от верхних прорезей 5 через контейнер и формующее полотно во всасывающее средство 5« Вертикальный воздущньй поток с волокном бумаги пропускаетс  через перфорированный участок вьтускной стенки,обеспечива  прохождение выпускаемых волокон из элемента трубы и передачу ихAir flow for the saturation of the fibrous material is supplied from a blower (not shown) through the inlet pipe 11, resulting in a flow of particles of material circulating in the tube element 4 and conductive means 8 "Individual fibers are discharged from this stream out through the perforated section of the outlet wall together With the excess air supplied through the inlet pipe 1 1, the Air is forced downwards from the upper slots 5 through the container and the forming web into the suction means 5 "Vertical air The flux of the fiber with the paper is passed through the perforated section of the vortex wall, ensuring the passage of the produced fibers from the pipe element and their transfer

вниз с распределением на формующем полотне.down with distribution on the forming fabric.

Воздух, направленный от верхних прорезей 15 вниз, обеспечивает дополнительное действие в части последовательной очистки наружной поверхности элемента трубы в ходе ее вращени , удал   оседающий на нижнем участке элемента трубы волокнистый материал противотоком направленного вниз воздуха. Очистка перфорации и наружной поверхности элемента трубы 4 возрастает благодар  использованию очистного средства 17, соединенного с источником сжатого воздуха. Элемент трубы содержит средство дл  об- работки материала, содержащее цилиндр 6 с радиальными перемешивающими стержн ми 7« Цилиндр установлен эксцентрично таким образом, чтобы стержни проходили вплотную к нижней внутренней поверхности элемента трубы 4. Это позвол ет концам стержней сметать возможные скоплени  волокна на внутренней поверхности элемента трубы и, кроме того, стержни создают эффект разбивани  комьев волокна и обеспечивают непосредственный выброс материала через перфорацию и проталкивание материала вдоль элемента трубы . Над цилиндром установлена неподвижна  экранирующа  пластина 20, служаща  дл  ограничени  направленного вниз воздушного потока с частицами материала, проход щего через перфорацию к формующему полотну.The air directed downward from the upper slots 15 provides an additional effect in part on sequential cleaning of the outer surface of the pipe element during its rotation, removing fibrous material deposited on the lower part of the pipe element with countercurrent downward air. Cleaning the perforation and the outer surface of the element of the pipe 4 increases due to the use of cleaning means 17 connected to a source of compressed air. The tube element contains a means for treating the material containing a cylinder 6 with radial mixing rods 7 "The cylinder is eccentrically mounted so that the rods extend close to the lower inner surface of the pipe element 4. This allows the ends of the rods to sweep away possible fiber accumulations on the inner surface the pipe element and, in addition, the rods create the effect of breaking up clods of fiber and provide a direct ejection of material through perforation and pushing the material along the element would A fixed screening plate 20 is installed above the cylinder to limit the downward air flow with particles of material passing through the perforations to the forming fabric.

Внутри элемента трубы расположен несущий элемент 18, соединенный с источником сжатого воздуха и имеющий воздушные насадки 19 дл  направлени  струй воздуха по внутренней поверхности элемента трубы, что приводит к качественному перемешиванию волокнистого материала и обеспечивает надежный выброс частиц материала на формующее полотно.Inside the pipe element is a carrier element 18 connected to a source of compressed air and having air nozzles 19 for directing air jets along the inner surface of the pipe element, which leads to good mixing of the fibrous material and ensures reliable ejection of material particles onto the forming fabric.
