The invention relates to the enrichment of minerals and is intended to stabilize and regulate the level of pulp in the chamber of a flotation machine, as well as to automatically regulate the production of the sand fraction of the pulp. The invention can be used in the coal, metallurgical, chemical and other industrial sectors.

The purpose of the invention is to improve the accuracy of the regulation of the level of the pulp and to ensure the automatic regulation of the discharge of the sand fractions.

The figure schematically depicts a pulp level stabilizer.

The pulp level stabilizer includes a pocket 1 communicated with the volume of the flotation machine through an outlet port 2 and a sand hole 3, a turning system consisting of an overflow tank 4, a counterweight 5, a gate valve 6 and a drain threshold height regulator 7 with a weight 8, side shields 9, a sand hole gate 10. The top edge of the gate 6 is a drain threshold. Pocket 1 has a discharge pipe 11. The regulator 7 is rigidly fixed to the wall of the overflow tank 4. The sand hole 3 is equipped with an elastic pipe 12. The shutter 10 is made in the form of a pinch element and connected to the swivel system by means of a pull 13 and ball 3517

the plane of the gate 6 and the plane passing through the axis of the PS and the drain threshold at the upper position of the gate 6 is 10-15 °. The pulp, discharged from the FM, is poured through the window 2 and the drain threshold in the PE 4 acting as a level sensor. With an increase in the pulp flow rate, the PS rotates, increasing the channel between pocket 1 and PE 4. When the pulp volume decreases, the PE 4 shifts towards FM and closes the channel, providing a reduction in pulp through the window 2 while maintaining the pulp level in the FM. 1 hp f-ly, 1 ill.

14. The angle between the plane of the gate 6 and the plane passing through the axis of the rotary system and the drain threshold at the upper position of the gate,

is 10-15 °.

The rotary system is fixed on the horizontal axis 16. The pulp level stabilizer works in the same way.

The pulp is discharged from the chamber of the flotation machine through a drain port 2 and a drain threshold into the overflow tank 4, which acts as a sensitive level sensor. When increasing the pulp flow rate, the rotary system rotates around an axis and increases the channel cross section between the wall of the pocket 1 and the overflow capacity 4. This ensures an increase in the flow rate of the discharge device while maintaining the pulp level unchanged in the flotation machine. At the same time, by means of the pull 13, the shutter 1 O is raised and the flow rate of the sand fraction of the flotation pulp is increased.

When the volume of the pulp to be discharged is reduced, capacity 4 is displaced in the direction of the wall of the flotation cell and, closing the channel between them, ensures a reduction in pulp flow through window 2 while maintaining the level of pulp in the flotation machine.

At the same time, a reduction in the discharge rate of the sand fractions is ensured.

Thus, precise regulation of the pulp level in the flotation machine and unloading of sand fracdias is achieved.
