Description

Изобретение относится к оборудованию для свеклосахарного производства, а именно к отстойникам для взвешенных частиц, преимущественно сатурационного сока и предназначено для применения в сахарной промышленности.The invention relates to equipment for sugar beet production, namely to sedimentation tanks for suspended particles, mainly carbonated juice, and is intended for use in the sugar industry.

Известен отстойник для пульп с наклонными поверхностями осаждения, расположенными друг над другом. Поверхности осаждения выполнены в виде усеченных конусов, обращенных большим основанием вниз и насаженных друг над другом на центральной трубе, снабженной продольными щелями для сбора осветленного раствора и плавающей вместе с конусами в пульпе с целью сообщения им вибрационных движений для равномерного сползания осадка с поверхностей конусов и частичного его уплотнения (1).Known sump for pulps with inclined deposition surfaces located one above the other. The deposition surfaces are made in the form of truncated cones facing down with a large base and mounted on top of each other on a central tube equipped with longitudinal slots for collecting clarified solution and floating together with the cones in the pulp in order to inform them of vibrational movements for uniform sliding of sediment from the surfaces of the cones and partial its seals (1).

Этот отстойник не может бьпь использован .для осветления сока и сгущения осацка сатурационных соков в свеклосахарном производстве, так как при разделении необходимо получить 80% осветвленной фазы и 20% сгущенной суспензии, а при отводе осветленной фазы через продольные щели центральной трубы не позволит обеспечить хорошее качество осветленного сока, ввиду увеличения скорости на отводе и в результате чего воз5 можен унос мелкодисперсных частиц сатурационного осадка в декантат. В данной конструкции также имеет место пересечение потоков, поступающего в пространство между усеченными конусами исходного сока и от¹⁰ водимого с конических поверхностей осадка, что способствует взмучиванию сока и разбавлению сгущаемого сатурационного осадка.This clarifier cannot be used. For clarification of juice and thickening of sedimentary saturation juices in sugar beet production, since separation requires obtaining 80% of the clarified phase and 20% of the condensed suspension, and when the clarified phase is removed through the longitudinal slots of the central pipe, it will not be possible to ensure good quality clarified juice, due to an increase in the speed at the outlet, and as a result of which, fine particles of the saturation sediment can be carried into the decantate. In this design, there is also the intersection of flows entering the space between the truncated cones of the initial juice and from ¹⁰ sediment brought from the conical surfaces, which contributes to the agitation of the juice and dilution of the thickened saturation sediment.

Наиболее близким по технической сущности к предлагаемому является /Отстойник для ¹⁵ сока свеклосахарного производства, содержащий цилиндрический корпус с коническим днищем, установленный в корпусе пакет конусообразных тарелок, обращенных большим ₂₀ основанием вверх, расположенную центральную трубу с отверстиями для подвода исходного сока, устройства для распределения последнего между тарелками и каналы для отвода осадок в днище корпуса..The closest in technical essence to the proposed one is / Sump for ¹⁵ sugar beet juice production, containing a cylindrical body with a conical bottom, a pack of cone-shaped plates facing ₂₀ large upside down, a central pipe with holes for supplying the initial juice, a device for distributing the latter between plates and channels for the removal of sediment in the bottom of the housing ..

Каждое устройство для распределения ис- f ходаого сока между тарелками состоит из ряда трубок, прикрепленных к трубе с отверстиями для подвода исходного сока 12]. Недостатком известной конструкции аппарата является то,. что подвод исходной суспензии в пространство между коническими перегородками с помощью множества труб не обеспечивает равномерное распределение осветляемой суспензии. Кроме того, отсутствие принудительного удаления осадка с поверхности тарелок в этом отстойнике увеличивает опасность залегания твердой фазы.Each device for distributing the initial juice f between the plates consists of a series of tubes attached to a pipe with holes for supplying the initial juice 12]. A disadvantage of the known apparatus design is that. that the supply of the initial suspension into the space between the conical partitions with the help of many pipes does not provide a uniform distribution of the clarified suspension. In addition, the absence of forced removal of sediment from the surface of the plates in this sump increases the risk of solid phase occurrence.
