(Patent of the Russian Federation for the invention of JsTs? 21 85892, publ. 07.27.2002)
Наиболее близкой к заявляемому изобретению по технической сущности и достигаемому результату является центрифуга, включающая корпус, ротор, состоящий из цилиндрической и конической частей с окнами для отвода жидкой фазы и окнами для выгрузки осадка и шнек, расположенный коаксиально ротору и выполненный в виде барабана с укрепленными на нем витками спирали ( патент Украины на полезную модель No 27997, опубл. 26.1 1.2007г.). Closest to the claimed invention to the technical essence and the achieved result is a centrifuge, comprising a housing, a rotor consisting of cylindrical and conical parts with windows for drainage of the liquid phase and windows for unloading sediment and a screw located coaxially to the rotor and made in the form of a drum with reinforced it turns the spiral (patent of Ukraine for utility model No 27997, publ. 26.1 of 1.2007g.).
В данном аналоге выгрузка твердой фазы осуществляется в одном месте - через окна для выгрузки твердой фазы, расположенные в районе меньшего основания конуса. In this analogue, the unloading of the solid phase is carried out in one place - through the windows for unloading the solid phase, located in the area of the smaller base of the cone.
К недостаткам наиболее близкого аналога следует отнести большие энергетические затраты на транспортирование твердой фазы шнеком вдоль всей длины цилиндрической части ротора к окнам ее выгрузки. The disadvantages of the closest analogue are the high energy costs of transporting the solid phase by the screw along the entire length of the cylindrical part of the rotor to the windows of its discharge.
В основу изобретения поставлена задача создания такой центрифуги осадительной, в которой за счет новой конструктивной формы ротора и шнека удалось бы обеспечить уменьшение энергетических затрат на транспортирование твердой фазы к окнам ее выгрузки. The basis of the invention is the task of creating such a precipitation centrifuge, in which, due to the new constructive form of the rotor and auger, it would be possible to reduce the energy costs of transporting the solid phase to the windows of its discharge.
Технический результат, достигаемый при использовании данного изобретения, заключается в снижении энергетических затрат на транспортирование твердой фазы к окнам ее выгрузки. The technical result achieved when using this invention is to reduce the energy costs of transporting the solid phase to the windows of its discharge.
Данный технический результат достигается тем, что центрифуга осадительная, включающая корпус, установленный в нем ротор, состоящий из двух частей, одна из которых представляет собой усеченный конус, а другая - цилиндр, усеченный конус большим основанием соединен с цилиндром, в усеченном конусе выполнены окна для выгрузки твердой фазы, расположенный внутри коаксиально ротору шнек, выполненный в виде барабана с укрепленными на нем витками спирали, согласно изобретению, в
роторе с противоположной стороны дополнительно сформирован второй усеченный конус, в котором выполнены отверстия для отвода жидкой фазы, при этом часть шнека, расположенная в усеченном конусе с окнами для выгрузки твердой фазы имеет шаг, выполненный последовательно увеличенным в сторону окон для выгрузки твердой фазы. This technical result is achieved by the fact that the centrifuge is precipitating, comprising a case, a rotor installed in it consisting of two parts, one of which is a truncated cone and the other is a cylinder, a truncated cone is connected to the cylinder by a large base in a truncated cone unloading of the solid phase, located inside the screw coaxial to the rotor, made in the form of a drum with coils of a spiral fastened on it, according to the invention, on the opposite side of the rotor, a second truncated cone is additionally formed, in which holes are made to drain the liquid phase, while the part of the screw located in the truncated cone with windows for unloading the solid phase has a pitch made successively increased in the direction of the windows for unloading the solid phase.
При этом, отверстия для отвода жидкой фазы имеют заслонки разного уровня относительно оси центрифуги. At the same time, the holes for drainage of the liquid phase have valves of different levels relative to the centrifuge axis.
Анализ сопоставления с наиболее близким аналогом свидетельствует, что в роторе с противоположной стороны дополнительно сформирован второй усеченный конус, в котором выполнены отверстия для отвода жидкой фазы, при этом часть шнека, расположенная в усеченном конусе с окнами для выгрузки твердой фазы имеет шаг, выполненный последовательно увеличенным в сторону окон для выгрузки твердой фазы. Analysis of comparison with the closest analogue indicates that a second truncated cone is additionally formed in the rotor on the opposite side, in which holes are made to drain the liquid phase, while the part of the screw located in the truncated cone with openings for unloading the solid phase has a step that is sequentially increased towards the windows for unloading solid phase.
При этом, отверстия для отвода жидкой фазы имеют заслонки разного уровня относительно оси центрифуги. At the same time, the holes for drainage of the liquid phase have valves of different levels relative to the axis of the centrifuge.
Причинно-следственная связь между совокупностью существенных признаков технического решения и достигаемым техническим результатом заключается в следующем. A causal relationship between the set of essential features of a technical solution and the technical result achieved is as follows.
В противоточной центрифуге, в которой твердая фаза двигается в одну сторону, а жидкая фаза -в противоположную, достигается снижение энергетических затрат за счет вышеназванных признаков. In a countercurrent centrifuge, in which the solid phase moves in one direction, and the liquid phase in the opposite direction, a reduction in energy costs is achieved due to the aforementioned features.
В данном техническом решении ротор состоит из двух усеченных конусов и цилиндра, что обеспечивает снижение энергетических затрат на транспортирование твердой фазы вдоль образующей усеченного конуса, чем вдоль образующей цилиндра ( как в наиболее близком аналоге ). In this technical solution, the rotor consists of two truncated cones and a cylinder, which reduces the energy costs of transporting the solid phase along the generatrix of the truncated cone than along the generatrix of the cylinder (as in the closest analogue).
Выполнение части шнека, расположенной в усеченном конусе с окнами для выгрузки твердой фазы с шагом, выполненным последовательно увеличенным в сторону окон для выгрузки твердой фазы, способствует уменьшению давления на твердую фазу, при этом снижается коэффициент
трения, что также обеспечивает снижение энергетических затрат, т.е. достижение технического результата. The implementation of the auger part located in a truncated cone with windows for unloading the solid phase with a pitch made successively increased in the direction of the windows for unloading the solid phase, reduces the pressure on the solid phase, while reducing the coefficient friction, which also reduces energy costs, i.e. the achievement of the technical result.
В частном случае выполнения окна для отвода фугата имеют заслонки разного уровня относительно оси центрифуги, что позволяет разделять легкую фракцию жидкости от тяжелой. In the particular case of the window for withdrawing the centrate, the valves have different levels relative to the axis of the centrifuge, which makes it possible to separate the light fraction of the liquid from the heavy.
Сущность изобретения поясняется чертежом, где на фиг. изображен общий вид центрифуги. The invention is illustrated in the drawing, where in FIG. shows a general view of the centrifuge.
Центрифуга осадительная содержит корпус 1 , установленный в нем ротор 2, состоящий из двух частей, одна из которых выполнена в виде цилиндра 3, вторая - в виде усеченного конуса 4, который соединен своим большим основанием с цилиндром 3. The precipitation centrifuge includes a housing 1, a rotor 2 installed in it, consisting of two parts, one of which is designed as a cylinder 3, the second - as a truncated cone 4, which is connected by its large base with cylinder 3.
В роторе 2 с противоположной стороны дополнительно сформирован второй усеченный конус 5. В усеченном конусе 4 выполнены окна 6 для выгрузки твердой фазы. Во втором усеченном конусе 5 расположены отверстия 7 для отвода жидкой фазы. A second truncated cone 5 is additionally formed in the rotor 2 on the opposite side. Windows 6 are formed in the truncated cone 4 for unloading the solid phase. In the second truncated cone 5 there are holes 7 for drainage of the liquid phase.
Внутри ротора 2 коаксиально последнему расположен шнек 8, выполненный в виде барабана 9 с укрепленными на нем витками спирали 10. Inside the rotor 2 coaxially the last is a screw 8, made in the form of a drum 9 with coils of a spiral 10 fixed on it.
Часть 1 1 шнека 8 имеет шаг L, выполненный последовательно увеличенным в сторону окон для выгрузки твердой фазы 6. Part 1 1 of the screw 8 has a step L, performed successively increased in the direction of the windows for unloading the solid phase 6.
Центрифуга оборудована трубой питания 12 для подачи суспензии в ротор 2. The centrifuge is equipped with a feed pipe 12 for supplying the suspension to the rotor 2.
Оверстия для отвода жидкой фазы 7 имеют заслонки 13 разного уровня относительно оси 0-0 ' . The openings for drainage of the liquid phase 7 have flaps 13 of different levels relative to the axis 0-0 '.
Центрифуга работает следующим образом. The centrifuge works as follows.
Суспензия, подлежащая разделению, по трубе питания 12 попадает в ротор 2 центрифуги, заполняет ротор.
В роторе 2 под воздействием центробежных сил, образующихся при вращении ротора 2, происходит разделение суспензии на твердую фазу и жидкую. The suspension to be separated, through the supply pipe 12 enters the rotor 2 of the centrifuge, fills the rotor. In the rotor 2 under the influence of centrifugal forces formed during the rotation of the rotor 2, the suspension is divided into a solid phase and a liquid.
Твердая фаза отбрасывается к стенкам ротора 2. The solid phase is thrown to the walls of the rotor 2.
Витки спирали 10 шнека 8 перемещают твердую фазу вдоль усеченного конуса 4 ротора к окнам для выгрузки твердой фазы 6. The coils of the spiral 10 of the screw 8 move the solid phase along the truncated cone 4 of the rotor to the windows for unloading the solid phase 6.
Жидкая фаза, образующаяся в процессе разделения суспензии, течет в противоположном направлении - к отверстиям для отвода жидкой фазы 7, размещенным в части 5 ротора 2. The liquid phase formed in the process of separating the suspension flows in the opposite direction - to the holes for draining the liquid phase 7 located in part 5 of the rotor 2.
Таким образом, данное техническое решение обеспечивает снижение энергетических затрат на перемещение твердой фазы к окнам ее выгрузки.
Thus, this solution provides a reduction in the energy costs of moving the solid phase to the windows of its discharge.
