Abstract

This invention relates to the beneficiation of minerals. The purpose of the invention is to save materials and reduce operating costs. The impeller block installed in the chamber consists of a bearing housing, a hollow shaft with an impeller (I) and a pulley. The central part of And consists of a hollow shank 6, on which a removable peripheral part I is installed between the upper 7 and lower 8 clamping elements (E). The latter is designed as a removable unit including a ring with radial holes coaxially with which the frames of 11 hollow blades are placed 12. The ring is fixed between the E 7 and 8 coaxial nut 13 on the landing edges 14. When assembling and installing it on the shaft, the ring and the frames 11 of the blades 12 are installed between the E 7 and 8 to mate with the edges 14 and screwed to the stop at the end E 7 nut 13. Then thread th part of the shank 6 and is screwed onto the shaft. 3 il.

J; k) shaving refers to the enrichment of 111) le: shih minerals and is intended for the auratization of pulp in flotation machines.

The aim of the invention is to save materials and reduce operating costs by preventing the edges of the central part of the impeller unit from wearing out and its repeated use when replacing the impeller unit from the removable peripheral part.

FIG. 1 shows a flotation cell, a schematic section; in fig. 2 shows a section of impellers and its shaft in the case of bl (blade blades made of frames hemmed with a ring, section A-A in Fig. I; Fig. 3 impeller, top view, with a section of the blade and a gummed ring with radial holes mi

In the chamber 1 there is an impeller block consisting of a body of the under-rim 2, a hollow base: with impeller 4 and pulley 5. Impeller / C 4 pmset peripheral and central parts,

The central part consists of a shank of the shank 6, on which between the upper clamping element 7 and the lower clamping element 8 there is a peripheral part of the impeller, made in the form of a removable unit, including a ring () ring 9 with radii1,1mp holes 10, aligned with, which are placed frames 11 of the blades 12,. ag miarovaynye ring 9, Zak) blind between the clamping elements 7 and 8 coaxial iMiiKoii 1 .S along the landing edges 14.

The impeller is assembled and mounted on the shaft as follows.

The removable unit (9, 10, 11, 12) is installed between the upper and lower clamping elements 7 and 8 to mate with the seating edges 14 and screw the coaxial nut 13 until the stop at the end of the upper clamping element 7, after which the impeller 4 remains The threaded part of the shank 6 is screwed onto the hollow shaft 3.

When replacing the worn out removable unit, the disassembly is carried out as follows: the impeller 4 is screwed off the shaft 3, the coaxial nut 13 is unscrewed and the removable unit (9, 10, 11, 12) is released from the upper and lower clamping elements 7 and 8 and fixed on new.
