笔者根据欧洲专利局84—85发布的专利,就以下三种新型的浮选设备作简要介绍: (一)瀑落式浮选机 瀑落式浮选机,是通过入选物料在空气中自由瀑落以增大充气量,产生大量泡沫,从而提高分选效果的。该设备如图1所示。已调节好的矿浆,经由进料管1进入分配箱2,由文丘里充气管3充气后,经出料管4在空气中自由瀑落。充气量的大小,可用出料管的多少来调节。瀑落的物料经档圈5进入容器6。大量的充气就是在物料自由瀑落、撞击液面产生喷溅时实现的。护罩7用以减少瀑落时的喷溅量,其高低位置可以调节。档板8可放置在液面之上,抑可置于液 The author according to the European Patent Office 84-85 issued a patent, the following three new types of flotation equipment for a brief introduction: (a) waterfall fall flotation machine flotation machine, through the selected materials in the air free waterfall Fall to increase the amount of inflatable, resulting in a large number of foam, thereby enhancing the sorting effect. The device shown in Figure 1. Adjusted pulp, through the feed pipe 1 into the distribution box 2, the Venturi inflatable tube 3 inflated after the discharge pipe 4 free fall in the air. The size of the amount of inflation can be used to regulate the number of discharge pipe. Falling material through the file ring 5 into the container 6. A large number of inflatable is free fall in the material, the impact of splashing achieved. Shroud 7 to reduce the amount of splash when falling, the height position can be adjusted. Baffle 8 can be placed above the liquid level, can be placed in the liquid
