    The invention relates to a repeating flotation machine for floating minerals from sludges. The repeating flotation machine comprises a flotation cell (1) and a repeat flotation cell (16) placed therein. Inside each cell there is placed a mixer apparatus composed of a stator-rotor combination (2, 3; 17, 18).

    专利说明:

    This invention relates to a multistage flotation machine for the flotation of minerals and the like. materials, and can be applied, in particular, in flotation processes using raw materials with a low content of valuable mineral, i.e. low content of poor concentrate in the total amount of feedstock fed to the process, as well as in flotation processes in which high quality of the poor concentrate obtained is achieved during a multi-stage flotation process.
    The purpose of the invention is to change the size of the machine and reduce the cost of transporting flotation products. The drawing shows a diagram of the machine. Inside the flotation cell 1, there is a mixer with a stator 2 and a rotor 3. The rotor 3 is attached to a hollow shaft 4 mounted in bearings 5 and 6 attached to the supporting structures of the chamber. The shaft 4 is driven in rotation by the drive 7 through a 8-step speed belt drive. Through the hollow shaft 4, air is supplied to the rotor 3. The air inlet tube is marked with 9.
    The bottom of the flotation cell is made in the form of a cone 10. In the lower part of this cone, an opening is made with a pipe connection 11 for removal of waste from the chamber. A feed pipe 12 is installed at the bottom of the chamber, providing sludge directly to the zone of action of the rotor flow, washing away the blades of the stator 2. The feed pipe 12 is installed with the possibility of adjusting its vertical position.

    The stator 2 with the aid of bolts 13 krech pits to the bottom of the chamber with the formation of a gap of several centimeters between the bottom of the chamber and the stator bottom. The stator 2 has a bottom 14.
    The material enriched in the first stage through the foam container 15 is discharged from the flotation chamber 1 and introduced into the smaller re-flotation chamber 16 installed inside the flotation chamber 17 The re-flotation chamber does not differ in design from the flotation chamber 1 and contains a mixer from the rotor 17 and the stator 18. Rotor mounted on shaft 4} i. Mixers of both chambers are placed on a common shaft. The concentrate coming from the large flotation chamber through the sump box 15 through the inlet pipe 19 installed below the overflow threshold is fed to the mixing zone of the re-flotation chamber 16 due to the suction effect of the rotor. The resulting flotation concentrate is removed from the chamber 16 of the repeated flotation tube through the sump 20 and the discharge pipe 21 passing through the large chamber. Waste from the secondary flotation process under the action of hydrostatic pressure is recycled to the flotation cell 1 through an opening 22 formed in the bottom 23 of the re-flotation chamber.
    Through a special pipe 24, downstream of the rotor, air is supplied for use by this mixer of the re-flotation cell J6. The secondary flotation chamber is attached to the supporting structure, to which the mixer bearings are attached. The drawing shows a device in which the mixers of both the large flotation cell and the secondary flotation cells have a common shaft and are driven from a single drive unit.
    The machine works as follows.
    When the raw material is fed through the feed pipe 12 into the stream created by the rotor 3 and the stator 4, solid particles are separated, resulting in floating light particles remaining afloat, while larger and heavier particles sink directly to the bottom of the flotation cell 1. Since Between the stator and the bottom of the flotation cell 1 there is a gap, large particles can freely pass under the bottom of the stator 4 and move through the pipe 11. The bottom plate 14 of the stator 2 prevents large particles from lifting into the suction zone of the rotor, thereby eliminating the impractical and equipment wearout circulation of coarse material inside the chamber.
    The pop-up product is collected in the foam container 15 and through the inlet pipe 19 enters the mixing zone of the re-flotation chamber 16, where it is subjected to the re-flotation operation. The foam product from the re-flotation chamber 16 is removed through the sump 20 and the discharge pipe 21.
    The arrangement of the chambers of the multistage flotation machine allows the use of a gap formed around the shaft, which is otherwise a useless space from the point of view of the flotation process.
    If the volume of the secondary flotation chamber is 1/10 of the volume of the large chamber, then the diameter of the rotor of the secondary flotation chamber in the preferred embodiment should be 60-80% of the diameter of the rotor of the large chamber.
    A secondary flotation cell can be installed in a large flotation unit.

    The camera is not only coaxial, although coaxial installation is the most rational from the point of view of the process taking place in a large chamber. In particular, when using large flotation cells, there is a risk of vortex flows causing the rotation of both the foam material and the sludge, i.e. whole material. All these negative effects can be eliminated due to the installation inside the large secondary flotation cell.
