Description
Изобретение предназначено дл разделени жидких неоднородных сил в -поле действи центробежных сил и может использоватьс в калийной промышленности.The invention is intended to separate liquid inhomogeneous forces in the α-field of centrifugal forces and can be used in the potash industry.
Известны шнековые центрифуги, включающие ротор с окнами дл выгрузки осадка и фугата, питающий патрубок, шнек, содержащий -полый барабан и винтовую направл ющую с внутренним каналом (1).Screw centrifuges are known, including a rotor with windows for discharging sediment and a centrifuge, a feed nozzle, an auger containing an-hollow drum and a screw guide with an internal channel (1).
Недостатком этой центрифуги вл етс низка частота фугата из-за нарущени ламинарности потока поступающей суспензии.The disadvantage of this centrifuge is the low frequency of the centrate, due to the disruption of the laminar flow of the incoming slurry.
Целью изобретени вл етс повышение эффективности разделени за счет улучщени гидродинамического режима в роторе.The aim of the invention is to increase the separation efficiency by improving the hydrodynamic conditions in the rotor.
Дл этого внутренний канал винтовой направл ющей расположен в зоне ввода суспензии и св зан с питающим патрубком. Кроме того, внутренн поверхность канала выполнена из износостойкого материала.For this, the inner channel of the helical guide is located in the zone of the slurry inlet and is connected to the supply pipe. In addition, the inner surface of the channel is made of wear-resistant material.
На чертеже схематически изображена щнекова центрифуга.The drawing shows a schematic of a shnekova centrifuge.
Она содержит ротор 1 с окнами 2 и 5 дл выгрузки осадка и фугата, питающий натрубок 4 и щнек, содержащий .полый барабан 5 и винтовую направл ющую 6 внутренним каналом . Канал имеет стенки 7 и 8. Стенка 7 обращена в сторону окон 3 дл выгрузки фугата и имеет радиус, равный радиусу витков направл ющей 6. Стенка 8 обращена в сторону окон 2 дл выгрузки осадка и радиус ее меньще радиуса остальных BHTIKOB. Поверхности направл ющей 6 и стенок 7 и S выполнены «3 износостойкого материала.It contains a rotor 1 with windows 2 and 5 for discharging sediment and a fugate, feeding the pipe 4 and cheeks, containing a hollow drum 5 and a screw guide 6 by an internal channel. The channel has walls 7 and 8. The wall 7 faces the windows 3 for discharging the centrifuge and has a radius equal to the radius of the turns of the guide 6. Wall 8 faces the windows 2 for unloading the sediment and its radius is smaller than the radius of the remaining BHTIKOB. The surfaces of the guide 6 and the walls 7 and S are made of "3 wear-resistant material.
Работает центрифуга следующим образом.Works centrifuge as follows.
Суспензи поступает но питающему патрубку 4 в полость барабана 5, вращающегос в ту же стороиу, что и ротор /, «о с несколько отличной скоростью. Попада на периферию барабана, суспензи далее направл етс действием центробежной силы во внутренний канал .направл ющей бив полость poTdpa. Турбулентность жидкости будет снижена в поверхностных сло х за счет плавного обтека ни суспензией винтовой направл ющей . ,В результате снизитс вынос осадка с фугатом и повыситс эффективность разделени .The suspension enters but feeds the nozzle 4 into the cavity of the drum 5, rotating in the same direction as the rotor 1, with a slightly different speed. Getting to the periphery of the drum, the suspension is further directed by the action of centrifugal force into the internal channel of the biplane guiding cavity poTdpa. The turbulence of the fluid will be reduced in the surface layers due to a smooth flow around the slurry of the helical guide. As a result, sediment discharge with the centrate will decrease and separation efficiency will increase.
