Abstract

Изобретение относитс к обогащению полезных ископаемых. Цель изобретени - повышение показателей процесса флотации за счет повышени плотности и снижени зольности пенного продукта путем увеличени времени обезвоживани . Флотационна машина содержит камеру 1 с аэратором 2 и пенными желобами 10. У бортов камеры расположено пеносьемное приспособление 3 в виде лопастей, закрепленных на валу 9. Лопасти выполнены из шпальтовых колосников 6 и 8, закрепленных на дугообразных каркасах 5 посто нной кривизны и колосниковой стенке 7, выполненной в виде V-образной рамы. При этом рама расположена с тыльной стороны по направлению вращени вала 9 от каркасов 5. Радиус кривизны каркасов 5 равен рассто нию от их свободных краев до оси вала 9. Рассто ние между свободными кра ми каркасов 5 и стенки 7 равно 0,50-0,53 радиуса кривизны каркасов 5. Колосники 6 и 8 на каркасах 5 и стенке 7 закреплены параллельно уровню пульпы в камере 1. При вращении аэратора 2 пульпа в камере 1 аэрируетс . Пенный слой с поверхности ,пульпы периодически сгребаетс лопаст ми в желоба 10. При нахождении на лопаст х пена обезвоживаетс и обесшламливаетс . 2 з.п. ф-лы, 3 ил.This invention relates to the beneficiation of minerals. The purpose of the invention is to increase the performance of the flotation process by increasing the density and decreasing the ash content of the froth product by increasing the dewatering time. The flotation machine contains a chamber 1 with an aerator 2 and foam chutes 10. At the sides of the chamber there is a foam device 3 in the form of blades fixed on the shaft 9. The blades are made of spalted grates 6 and 8 fixed on arcuate frames 5 of constant curvature and grate wall 7 made in the form of a V-shaped frame. The frame is located on the rear side in the direction of rotation of the shaft 9 from the frames 5. The radius of curvature of the frames 5 is equal to the distance from their free edges to the axis of the shaft 9. The distance between the free edges of the frames 5 and wall 7 is 0.50-0, 53 radii of curvature of the frames 5. The grate 6 and 8 on the frames 5 and wall 7 are fixed parallel to the level of the pulp in chamber 1. When the aerator 2 is rotated, the pulp in chamber 1 is aerated. The foam layer from the surface, pulp, is periodically scraped by the blades in the chutes 10. When placed on the blade, the foam dehydrates and slimes. 2 hp f-ly, 3 ill.

Claims

Claim

1. A flotation machine, comprising a chamber with an aerator and foam troughs and a foam device fixed at its sides, consisting of blades mounted on a shaft, characterized in that, in order to increase the performance of the flotation process by increasing the density and reducing the ash content of the foam product, each the blade is made of bobbin grates located on a V-shaped on a frame and an arcuate in cross section of a frame of constant curvature, while the frame is located in the direction of rotation of the shaft from the rear torons from an arched frame.

2. The machine according to claim 1, with the fact that the radius of curvature of the arcuate frames is equal to the distance from their free edges to the axis of the shaft, and the distance between the free edges of the frame and frame is 0.50-0 , 52 radius of curvature of the frames.

3. The machine according to paragraphs. 1 and 2, this is due to the fact that the gusset grates on the frames and the frame are fixed parallel to the pulp level in the chamber.
