Description

(54) ЦЕНТРОБЕЖНЫЙ СЕПАРАТОР(54) CENTRIFUGAL SEPARATOR

II

Изобретение относитс к обогащению полезных ископаемых, в частности дл разделени материала по удельному весу.The invention relates to the enrichment of minerals, in particular for the separation of material according to specific gravity.

Известен центробежный сепаратор дл обогащени золотосодержашрих песков и руд, включающий установленную на раме коническую чашу с нарифлени ми , загрузочное и разгрузочное приспособлени , привод. Нарифлени имеют переменные щаг и глубину A centrifugal separator for enriching gold sands and ores is known, including a conical bowl mounted on a frame with grooves, loading and unloading devices, and a drive. Nafleneni have variable schag and depth

Цель изобретени - повышение йзт влечени т желых частиц полезного компонента.The purpose of the invention is to increase the attraction of heavy particles of the useful component.

Указанна цель, достигаетс тем,, что нарифлени расположены под острым углом к проекции образуи цей чаши в плоскости, перпендикул рной к оси чаши.This goal is achieved by the fact that the edges are located at an acute angle to the projection of the bowl in a plane perpendicular to the axis of the bowl.

На фиг. 1 изображен сепаратор, .продольный разрезj на фиг. 2 - то же, сечение А-А на фиг. 1.FIG. 1 shows a separator, a longitudinal section j in FIG. 2 is the same, section A-A in FIG. one.

Центробежный сепаратор включает чашу I, установленную на раме 2 с приводом 3. Чаша внутри снабжена нарифлени ми 4. Сверху чагаи 1 расположены загрузочное йриспособление 5 дл подачи исходной пульпы, разгрузочное приспособление 6 дл хво10 стов и желоб 7 дл концентрата. Нарифлени 4 расположены под острым yrnoM-ci к проекции образующей чаши в плоскости, перпендикул рной к оси чаши.The centrifugal separator includes a bowl I mounted on frame 2 with a drive 3. The bowl inside is supplied with lights 4. On top of chaga and 1 there is a loading device 5 for feeding the original pulp, a discharge device 6 for the tails and a chute 7 for concentrate. The edges 4 are located under the sharp yrnoM-ci to the projection of the generator of the bowl in a plane perpendicular to the axis of the bowl.

ISIS

Устройство работает следующим образом . Чаше 1 сообщаетс вращение от привода 3,. через загрузочное приспособление 5 в чашу 1 подаетс исходный материал в виде пульпы. The device works as follows. On 1, rotation from drive 3 is reported. through the loading device 5, the raw material in the form of pulp is fed into the bowl 1.

Claims

20 Under the action of centrifugal force, the pulp moves upward along the inner surface of the bowl b, while the heavy mineral particles are held up by the edges 4, and the light particles of the tails are merged with the water through the discharge device 6.. Higher extraction of heavy particles of the useful component in comparison with the known device is achieved due to the passage of each particle of a large number of patterns, which is provided by their location perpendicular to the movement of the material. After the processing of a certain portion of material is completed, its supply stops, the direction of rotation of the bowl changes, and water is fed into the bowl. The heavy particles are washed out of the filaments into the chute 7. Then the direction of rotation of the bowl is changed, the original pulp is fed into it, and the cycle is repeated i / 4 Using the proposed device allows increasing the extraction of heavy particles by 7-10%. Claims of the invention: A centrifugal separator comprising a conical bowl mounted on a frame with grooves, loading and unloading devices, and a drive characterized in that, in order to increase the extraction of heavy particles of the useful component, the tips are arranged at an acute angle to the projection forming the cups in the plane, perpendicular to the bowl axis.
