Description

Изобретение относитс к разделению суспензий, в частности, к сепа-раторам , и может быть использовано в пищевой, химической и других отрасл х промышленности.The invention relates to the separation of suspensions, in particular to separators, and can be used in the food, chemical and other industries.

Известны- сепараторы, состо щие из барабана со шламовым пространством , полого вала с установленными на нем с зазорами конических тарелок и устройствами подачи суспензии через шламовое пространство и отвода фугата через кольцевое отверстие между барабаном и полым валом l}.Known are separators consisting of a drum with a slurry space, a hollow shaft with conical plates mounted on it with gaps and suspension supply devices through the slurry space and removal of a centrate through an annular opening between the drum and the hollow shaft l}.

Недостаток данного устройства состоит в низкой эффективности разделени из-за захвата твердой фазы, осаждающейс на тарелках и сползающей в шламовое пространство, противоположным потоком суспензии.The disadvantage of this device is the low separation efficiency due to the entrapment of the solid phase deposited on the plates and sliding into the slurry space, opposite to the flow of the suspension.

Наиболее близким по«технической сущности и достигаемому результату к предлагаемому вл етс сепаратор, содержащий ротор, полый вал с каналами подвода суспензии и отвода фугата, наклонные пластины, радиальные перегородки , образующие секторы пр 1моточной и противоточной сепарации 2.,The closest in technical essence and the achieved result to the proposed is a separator containing a rotor, a hollow shaft with channels for supplying slurry and withdrawal of centrate, inclined plates, radial partitions forming the sectors of direct current and countercurrent separation 2.,

Недостатком этой конструкции вл етс необходимость полной изол ции секторов друг от друга по внутреннейThe disadvantage of this design is the need to completely isolate the sectors from each other along the internal

и наружной конической поверхности тарелок в месте размещени радиальных перегородок, так как в случае перетечек суспензии ухудшаетс качество осветленной жидкости, т. е. снижаетс эффективность разделени .and the outer conical surface of the plates at the location of the radial partitions, since the quality of the clarified liquid deteriorates in the case of suspension overflows, i.e. the separation efficiency decreases.

Цель изобретени - повышение эффективности разделени .The purpose of the invention is to increase the efficiency of separation.

Поставленна цель достигаетс The goal is achieved

15 снабжен радиальными перегородками, закрепленными между каналами подвода суспензии и отвода фугата по всей высоте секторов пр моточной и противоточной сепарации, в которых 15 is equipped with radial partitions, fixed between the channels for supplying the suspension and withdrawal of the centrate over the entire height of the sectors of continuous and countercurrent separation, in which

20 установлены наклонные пластины.20 mounted inclined plates.

Кроме того, в секторах противоточной сепарации установлено количество наклонных пластин, большее количество пластин в секторе пр моточ25 ной сепарации.In addition, in the sectors of countercurrent separation, the number of inclined plates was established, the greater the number of plates in the direct separation sector.

Claims

30 with slit channels 2 for supplying slurry and channels 3 for removing clarified liquid, rotor 4, grit 5, packages of inclined plates 6 between which spines 7 are installed to form gaps between the plates, radial partitions 8 fixed on the shaft and forming sectors 9 continuous separation and countercurrent separation sectors 10. Radial partitions 8 are installed along the entire height of the sectors 10. The inclined plates 6 are held radially by the plate holder 11 fixed to the hollow shaft 1. The packages of the inclined plates b in each sector are pressed from below by the pressure figured plate 12. In the sectors 10 of countercurrent separation the number of inclined plates 6 led compared with sectors 9 of continuous separation. The separator works as follows. The suspension is fed into the hollow shaft 1 from which it enters the channels 2 and, moving to the periphery along the sectors of the continuous separation, is separated. The heavy phase is deposited on the lower surfaces of the inclined plates 6 and slides into the slurry space. The clarified slurry, moving over the upper surfaces of the inclined plates b, enters the sectors 10 of countercurrent separation, where it is refined and then enters channel 3 and is withdrawn from the separator. Since the clarified slurry entering sectors 10 contains a small amount of solid particles, most of them fine, the gaps in these sectors are reduced. The proposed device, due to the reliable tightness of the sectors of the p-thread and counter-current separation, eliminates the mixture of the initial suspension and clarified liquid. An increase in the number of inclined plates in the sectors of countercurrent separation ensures a higher separation efficiency due to the smaller path of deposition of particles of the active phase and simultaneous development of the deposition surface. Claims of the invention: A separator containing a rotor, a hollow shaft with channels for supplying slurry and centrifuge, inclined plates and sectors of continuous and countercurrent separation, characterized in that, in order to increase separation efficiency, the hollow shaft is provided with radial baffles fixed between the channels for supplying slurry and discharging fugat across the entire height of the sectors of continuous flow and countercurrent separation, in which inclined plates are installed. 2. A separator according to claim 1, characterized in that in the sector of countercurrent separation, the number of inclined plates is established, the greater the number of plates in the sector of continuous separation.
