Description
Изобретение относитс к оборудованию дл обезвоживани волокнистых материалов и-может найти применение в целлюлозно-бумажной промышленности.The invention relates to equipment for the dewatering of fibrous materials and may be used in the pulp and paper industry.
Известны устройства дл обезвоживани волокнистых материалов, содержащие две бесконечные сетки, клиновую, и прессовую группы валков, а также приводные, поддерживающие и отклон ющие валки.Devices for the dewatering of fibrous materials are known, comprising two endless grids, a wedge and a press group of rolls, as well as drive, support and deflecting rolls.
Цель изобретени - повыщение степени обезвоживани волокнистых материалов.The purpose of the invention is to increase the degree of dehydration of fibrous materials.
Достигаетс это тем, что валки прессовой группы выполнены с уменьшающимис диаметрами и установлены с уменьшающимис межцентровыми рассто ни ми по ходу движени сеток. На выходе бесконечных сеток прессовой группы могут быть установлены два дополнительных валка, диаметр которых больше, чем диаметр остальных валков прессовой группы, образующих S-образный перегиб бесконечных сеток, а установленные за прессовой группой приводные валки могут быть смещены вниз относительно плоскости валков прессовой группы.This is achieved by the fact that the press rolls are made with decreasing diameters and are installed with decreasing center-to-center distances in the course of the movement of the grids. At the exit of the endless grids of the pressing group, two additional rollers can be installed, the diameter of which is larger than the diameter of the remaining rollers of the pressing group forming an S-shaped inflection of the endless grids, and the drive rolls installed behind the pressing group can be shifted downwards relative to the plane of the pressing group rolls.
На фиг. 1 дана принципиальна схема устройства; на фиг. 2 - устройство с двум дополнительными валками.FIG. 1 is a schematic diagram of the device; in fig. 2 - device with two additional rollers.
Устройство дл обезвоживани волокнистых материалов состоит из клиновой и прессовой группы валков. Клинова группа состоит из нижних валков 1 и постепенно приближающихс к ним верхних валков 2. Прессова группа состоит из нижних валков 3 и верхних валков 4, причем валки прессовой группы выполнены с постепенно уменьшаюшимис диаметрами и установлены с уменьшающимис межцентровыми рассто ни ми по ходу движени сеток. За прессовой группой расположены приводные валки 5 и 6. Устройство имеет отклон ющие 7 и 8, а также поддерживающие 9 и 10 валки, на которых нат нуты нижн 11 и верхн 12 бесконечные сетки. За прессовой группой валков могут быть установлены два дополнительные валка 13 и 14, диаметр которых больше, чем диаме-тр остальных валков прессовой группы, причем они образуют S-образный перегиб бесконечных сеток 11 и 12.A device for dewatering fibrous materials consists of a wedge and press group of rolls. The wedge group consists of lower rolls 1 and upper rolls 2 gradually approaching them. The press group consists of lower rolls 3 and upper rolls 4, the press group rolls are made with gradually decreasing diameters and are set with decreasing center-to-center distances. Behind the press group there are drive rolls 5 and 6. The device has deflecting 7 and 8, as well as supporting rolls 9 and 10, on which inflated nets 11 and top 12 are stretched. Two additional rolls 13 and 14, the diameter of which is larger than the diameters of the remaining rolls of the pressing group, can be installed behind the press group of rolls, and they form an S-shaped inflection of endless grids 11 and 12.
При работе устройства волокниста масса поступает в клиновую группу валков, где подвергаетс предварительному обезвоживанию. Валки в клиновой группе расположены один над другим. Валки 3 и 4 прессовой группы смещены по горизонтали один относительно другого , а их диаметры и межцентровые рассто ни постепенно уменьшаютс по ходу движени сеток. Благодар этому давление прессовани в прессовой группе валков возрастает и повышаетс конечна сухость волокнистого материала . Дальнейшее обезвоживание волокнистого материала происходит при его движении между сетками, образующими S-образную форму при помош,и валков 13 и 14, которые имеют диаметр больший, чем диаметры валков прессовой группы. Благодар этому увеличиваетс врем прессовани волокнистого материала, а следовательно , его сухость. Дл придани наклонного направлени обработанному в прессовом устройстве волокнистому материалу с целью упрощени его дальнейшей обработки за прессовой частью установлены приводные валки, которые несколько смещены вниз по вертикали, вследствие чего направление движени материала отклон етс вниз от горизонтали.During the operation of the device, the pulp enters the wedge group of rolls, where it is subjected to preliminary dewatering. The rolls in the wedge group are located one above the other. The rolls 3 and 4 of the press group are horizontally displaced one relative to the other, and their diameters and center-to-center distances gradually decrease as the grids move. Due to this, the pressing pressure in the press roll group increases and the final dryness of the fibrous material increases. Further dehydration of the fibrous material occurs when it moves between the grids that form an S-shape with the help of the rolls 13 and 14, which have a diameter larger than the diameters of the press rolls. This increases the pressing time of the fibrous material, and hence its dryness. In order to impart inclined direction to the fibrous material processed in the press device in order to simplify its further processing, drive rolls are installed behind the press section, which are shifted somewhat vertically downwards, as a result of which the direction of movement of the material deviates downward from the horizontal.
