(5) РАЗДЕЛИТЕЛЬ СУСПЕНЗИЙ(5) SEPARATION SUSPENSION

Изобретение относитс к устройствам дл разделени суспензий и может быть использовано в химической, пищевой, горнодобывающей и других отрасл х народного хоз йства дл сгущени суспензий.The invention relates to devices for the separation of suspensions and can be used in chemical, food, mining and other sectors of the national economy for the concentration of suspensions.

Известен разделитель суспензий дл выделени твердых частиц из дисперсной среды, включающий цилиндрический корпус, питающий патрубок, патрубок дл отвода осветленной и сгущенной фракций Clj.A known separator of suspensions for separating solid particles from a dispersed medium, comprising a cylindrical body, a supply nozzle, a nozzle for removal of clarified and condensed Clj fractions.

Недостатком его вл етс низка степень сгущени суспензий.The disadvantage of it is the low degree of thickening of the suspensions.

Наиболее близким по технической сущности и достигаемому результату к предлагаемому вл етс разделитель суспензий, содержащий корпус со спиральными транспортными перегородками , патрубки дл ввода исходной суспензии и вывода осветленной и сгущенной фракций С 2 3.The closest in technical essence and the achieved result to the proposed is a separator of suspensions, comprising a housing with spiral transport partitions, branch pipes for introducing the initial suspension and withdrawing the clarified and thickened C 2 3 fractions.

Недостатком его вл етс низка степень сгущени , обусловленна снижением скорости суспензии вдоль транспортного спирального канала. Разделитель суспензий сложен в конструктивном оформлении.The disadvantage of it is the low degree of condensation, due to the decrease in the rate of suspension along the transport spiral channel. The separator suspensions complex in a constructive design.

Цель изобретени - повышение эффективности разделени за счет увеличени окружной составл ющей скорости движени потока суспензии.The purpose of the invention is to increase the separation efficiency by increasing the circumferential component of the flow velocity of the suspension.

Поставленна цель достигаетс тем, что разделитель, содержащий корпус со спиральны.ми транспортными перегородками , патрубки дл ввода исходной суспензии и вывода осветленной и сгущенной фракций, снабжен ускорител ми потока и конической камерой с кольцевой перегородкой, при этом ускорители потока присоединены к корпусу в зонах патрубков ввода и спиральных транспортных перегородок по ходу движени суспензии, а коническа камера отделена от корпуса кольцевой перегородкой.The goal is achieved by the fact that the separator, comprising a housing with spiral transport partitions, branch pipes for introducing the initial suspension and withdrawal of clarified and condensed fractions, is equipped with flow accelerators and a conical chamber with an annular partition, while the flow accelerators are attached to the body in the zones of the branch pipes input and spiral transport partitions in the course of the suspension, and the conical chamber is separated from the body by an annular partition.

Ускоритель потока выполнен в виде тангенциально установленного к корпусу патрубка, соединенного с ис точником подачи разгонной жидкости.The flow accelerator is made in the form of a tangentially installed branch pipe to the body, which is connected to the source of the accelerating fluid supply.

На чертеже представлен разделитель суспензий, общий вид.The drawing shows the separator suspensions, General view.

Claims

The separator consists of a housing 1 with tangential nozzles 2 and 3 for introducing the suspension and withdrawal of the thickened fraction, a conical chamber 4 attached to the lower part of the housing and used for the withdrawal of the clarified liquid. Spiral trlnsport partitions 5 are reinforced to -casing 1 with BHyxpcHHet sides, and in the lower part - a conical chamber 4, which is separated by an annular partition 6 from the casing. nozzles 7. The separator suspensions works as follows. The suspension is fed through the tangential nozzle 2 into the upper part of the conical body 1 and twists. As a result of centrifugal forces, the solid particles are thrown to the walls and move along spiral transport partitions 5 to tangentially installed branch pipes 3, through which the thickened suspension is shocklessly removed from the apparatus. The clarified liquid moves to the spiral partitions 5 at some distance from the housing 1, then flows over the annular partition 6 and is withdrawn from the separator through the conical chamber 4. The accelerating fluid under a certain pressure is fed into the flow accelerators - additional nozzles 7, increases the speed of the suspension - this increases the degree of separation. The mode of operation of the apparatus is selected so that the bright liquid does not overflow between adjacent spiral transport partitions 5, but only over the annular partition 6. It is used in the input zones of the suspension and spiral transport partitions of flow accelerators in the form of additional pipes the body of the conical chamber, which is separated by an annular partition on it, makes it possible to significantly increase the separation efficiency by increasing the claiming the suspension movement velocity. The housing of the separator is made conical, tapering downwards, since in this case the circumferential flow rate will increase. An annular partition b located in the lower part serves to separate the clarified liquid from the thickened suspension. The proposed suspension separator is suitable for coarse separation, while reducing the load of existing filters, for example, drum in the production of extraction acid (when removing phosphogypsum). Claims 1. Suspension separator containing a housing with spiral trans. ; sport baffles, pipe n1p - input of the initial suspension and output of the clarified and condensed fractions, o-tl and t0m, which, in order to increase separation efficiency by increasing the circumferential component of the suspension flow velocity, a conical chamber with an annular partition; in this case, the flow accelerators are attached to the core in the zones of the inlet pipes and spiral transport partitions in the direction of the slurry, and the conical chamber is separated from the housing by an annular partition. 2. The separator of claim 1, wherein the flow accelerator is made in the form of a nozzle tangentially mounted to the body of the pipe connected to the source of the supply of the accelerating fluid.
