Description

The proposed apparatus aims to automatically obtain gold from the washed gold sands during continuous operation of the apparatus.

In FIG. 1 shows a vertical section of the apparatus; FIG. 2 shows the arrangement of gears rotating the mobile cones of the apparatus; FIG. 3 is a vertical section of a stationary cone with a tube and a worm shaft rotating in it.

Inside the iron cylinder, three fixed cones 63 (Fig. 1) are attached to its side walls, inside which are placed movable cones 62 with combs along the edges, a coupling. with gears J7, 18, driven by a gear 25-39 from the main shaft of the machine. Three pairs of cones 8, 9 are mounted on the main shaft between the cones 62-63, of which the cones 9 are fixed on the shaft tightly, and the cones 8 are serrated in the middle by meshing with gears 45, 46 attached to the cones 9 (49, 53- Fig. 2), which in turn are coupled with gears 47, which are freely seated on the main shaft and are attached by cones 48 to the bottom of overlying cones 63. Cones 63 (59) are provided with narrow slots 57 (Fig. 3), under which

there are tubes 19 (60) with screws 22 (64) rotating in them. Movable cones 62 (50-58) are lattices with brushes 56 placed above them, one end of which is attached to the walls of the cylinder and the other end to fixed cones 63; thus, the moving cones 62 move between the brushes 56 and the fixed cones 63.

The washed gold-bearing sand from the carriages 44 (Fig. 1) enters the basin, from which the bucket elevator 41 43 rises into the funnel-shaped hatch 40, from which, mixing with water coming through the pipe with the valve 37, is sent as a liquid mass to a rotating cone-shaped screen -grid 42, fortified on the main shaft. Without passing through the holes of the large rock, the pebbles due to the centrifugal force passes through the edge of the roar into the pipe 30 and from the latter to the car 31. After passing through the holes of the grate 42, a liquid mass of rock worms 26 driven by bevel gears 33 rotates to bucket elevators 27 whose buckets lift into the funnels 15-4 and from them enter the fixed cone 75; Here, the rock is stirred by stirrer 12 with water coming through pipe 14 and through the opening of the cone 75 enters slowly rotating cones 8, 9, of which the second is provided with a slit and tube 75 through which gold is transferred by centrifugal force to the lower cone, where it lingers in the holes of the grating of the moving cone 62, falls through the slot of the stationary cone 63 into the tube 19 and with the worm shaft of the tube 22 is fed through the tube 23 into the store 24. Sand, as light, flows through the edge of the cone 8 and merges along the walls of the apparatus to the underlying cone C 62, from which through the cone 48 will go to the following cones 8, 9 TL t. The washing process proceeds to the last cones 62, 63, from which the washing sand enters the chamber with the impeller 36, which is mixed and guided into the discharge pipe 30. All moving parts of the apparatus move the movement from the main shaft using worm, chain and cylindrical gears. There is a gearbox 10 for communicating with the main shaft of slow motion.

The subject matter of the invention.

1. An apparatus for extracting gold (platinum) from gold-bearing sand by washing, characterized by the use of those located in a cylindrical vessel equipped with

in the upper part, a funnel 75 with a stirrer 72 and water supply tubes 14 (Fig. 1), a) fixed cones 63, with cones and slow-moving cones 52, driven by combs 67, gears 77-18 and 25-39 gears from the main shaft, fitted with tubes 22 with a screw 64 for removing the moving cone-52 passing through the holes 5 (5-58 (fig. 3) and the fixed cone of gold (fig. 3) slit 57 reservoir 24, and b) double moving cones 8, 9, of which the second receives movement from the main shaft directly and provided with a slit and tube 16 for transferring gold by centrifugal force to the lower cones, to communicate the slower movement to the first cone, planetary gear 45-46, and to remove the rock, impeller 36 and branch pipe 30 (Fig. iT 2 and 3).

2. The form of the apparatus described in claim 1, characterized by using an elevator 43 for feeding gold-bearing sand to a grid 42 for separating it from coarse pebbles going into pipe 30, and screws 26 for feeding sand to elevators 27 located on both the sides of the washing vessel feeding the sand into the apparatus after pre-screening the pebbles and wetting them with water.
