Description

Изобретение относится к технике разделения соков свеклосахарного производства на сгущенный осадок дисперсной фазы и на чистую дисперсионную среду — декантат, а также для разделения других концентрированных суспензий непищевых производств с твердой или квазитвердой фазой.The invention relates to a technique for separating beet sugar juices into a condensed precipitate of a dispersed phase and a pure dispersion medium - decantate, as well as for the separation of other concentrated suspensions of non-food production with a solid or quasi-solid phase.

Известен отстойник, содержащий корпус, расположенную в его верхней части приемную камеру с горизонтальным распределителем, суспензии и скребковым механизмом для удаления осадка [1].Known sump containing a housing located in its upper part of the receiving chamber with a horizontal distributor, suspension and scraper mechanism to remove sediment [1].

Вертикальный снизу вверх ввод суспензии и восходящие потоки дисперсионной среды-снижают эффект действия силы тяжести. Без ₁₅ввода флокулянта, который загрязняет сок химикатами и снижает выход кристаллического сахара, он работать не может.Vertical from the bottom up the input of the suspension and the ascending flows of the dispersion medium — reduce the effect of gravity. Without ₁₅ injections of a flocculant, which contaminates the juice with chemicals and reduces the yield of crystalline sugar, it cannot work.

Цель изобретения — повышение эффективности использования устройства путем обеспечения 20процесса разделения режима свободного осаждения.The purpose of the invention is to increase the efficiency of use of the device by providing 20process separation mode of free deposition.

Указанная цель достигается тем, что стенки корпуса выполняются гиперболической формы.This goal is achieved by the fact that the walls of the housing are hyperbolic in shape.

На чертеже изображено устройство, общий вид.The drawing shows a device, General view.

Отстойник состоит из корпуса 1, приемной камеры 2 с плоским перфорированным распределителем 3, патрубками 4. Патрубки 5 и 6 предназначены для отвода соответственно газов и паров и суспензии. Шнек 7 скребкового транспортера 8 размещен в нижней части корпуса 1. В верхней части корпуса расположены отводящие трубки 9 приемника 10 декантата и патрубок 11. Под шнеком 7 размещена камера 12 сгущенного осадка с трубопроводом 13 и переливным ящиком 14.The sump consists of a housing 1, a receiving chamber 2 with a flat perforated distributor 3, nozzles 4. The nozzles 5 and 6 are designed to drain gases and vapors and suspension, respectively. The screw 7 of the scraper conveyor 8 is located in the lower part of the housing 1. In the upper part of the housing there are exhaust pipes 9 of the decanter receiver 10 and a pipe 11. Under the screw 7 there is a condensed sludge chamber 12 with a pipe 13 and an overflow box 14.

Устройство работает следующим образом.The device operates as follows.

В корпус 1 из приемной камеры 2 через горизонтальный перфорированный распределитель 3 поступает суспензия. Пары и газы отводятся патрубком 5. Избыточное количество суспензии удаляется по патрубку 6. Осевшая на днище дисперсная фаза перемешается шнеком 7 и транспортером 8 из устройства. Дскантат по отборным трубкам 9 поступает в приемник 10 и через патрубок 11 удаляется из корпуса.The suspension 1 enters the housing 1 from the receiving chamber 2 through a horizontal perforated distributor 3. Vapors and gases are discharged by the nozzle 5. An excess amount of the suspension is removed through the nozzle 6. The dispersed phase deposited on the bottom is mixed by the screw 7 and the conveyor 8 from the device. Dskantat through selected tubes 9 enters the receiver 10 and through the pipe 11 is removed from the housing.

Сгущенный осадок из камеры 12 отводится по трубопроводу 13 в переливной ящик 14.The thickened sediment from the chamber 12 is discharged through a pipe 13 to an overflow box 14.

Благодаря тому, что стенки корпуса отстойника выполнены гиперболической формы, осаждение концентрированных суспензий осущест- - вляется в условиях непрерывного прироста площади поперечного сечения и процессу в целом-, обеспечен режим свободного осаждения.Due to the fact that the walls of the sump body are made in a hyperbolic form, the deposition of concentrated suspensions is carried out under conditions of a continuous increase in the cross-sectional area and the process as a whole, the free deposition mode is ensured.

Claims

This invention relates to a technique for separating beet sugar production into condensed precipitate of a dispersed phase and into a decanted pure dispersion medium, as well as for separating other concentrated suspensions of non-food industries with a solid or quasi-solid phase. A settling tank is known, comprising a housing, in its upper part, a receiving chamber with a horizontal suspension distributor and a scraper mechanism for removing sediment 1. A vertical upward introduction of the suspension and ascending streams of the dispersion medium reduce the effect of gravity. Without entering flocculant, which contaminates juice with chemicals and reduces the yield of crystalline sugar, it cannot work. The purpose of the invention is to increase the efficiency of use of the device by providing a process for separating the free deposition regime. This goal is achieved by the fact that the walls of the body are hyperbolic in shape. The drawing shows the device, the overall appearance. The sump consists of a short-circuit of the housing 1, the receiving chamber 2 with a flat perforated distributor 3, pa tubes 4. The nozzles 5 and 6 are designed for removal of gases and vapors and suspensions, respectively. The auger 7 of the scraper conveyor 8 is located in the lower part of the housing 1. In the upper part of the housing there are discharging tubes 9 of the decantate receiver 10 and the spigot I. There is a condensed sludge chamber 12 with a pipeline 13 and overflow box 14 under the screw 7. Suspension enters the housing 1 from the receiving chamber 2 through a horizontal perforated distributor 3. The vapors and gases are removed by the nozzle 5. The excess amount of the suspension is removed along the nozzle 6. The dispersed phase settles on the bottom by the screw 7 and the conveyor 8 from the device. The decantate through the sampling tubes 9 enters the receiver 10 and is removed from the body through the nozzle 11. 3 The condensed sediment from chamber 12 is removed through conduit 13 to overflow box 14. Due to the fact that the walls of the sump body are made of a hyperbolic form, the concentration of concentrated suspensions precipitates under conditions of a continuous increase in the cross-sectional area and the process is provided with free sedimentation. A settling tank for separating polydisperse suspensions, comprising a housing, a receiving chamber located in its upper part with a horizontal perforated distributor and a mechanism for removing sludge, characterized in that in order to increase the efficiency of use by providing a free sedimentation separation process, the walls of the hull are made hyperbolic form.
