Description

With the existing methods of trapping precious metals, there is a significant demolition of those with the wash water, and the existing open devices do not guarantee against theft.

The present invention relates to an unknown type of apparatus with an upward flow of water and has the aim of eliminating the above disadvantages.

In FIG. 1 shows a top view of the apparatus without a funnel; FIG. 2 is a horizontal section along C-D in FIG. 3; the latter is a vertical section along ab-b in fig. 1, and FIG. 4 is a vertical section along the line C-D in FIG. one.

A funnel 1 is fitted to the upper part of the apparatus, into which water and rock passes. The end of the pipe 2 is connected to a pool with a constant water level or with a corresponding pump. Having established the apparatus in this way, it is put into operation, having previously been opened beyond the pore 3, and water flows through the tubes 4 through the tubes of the sprayers 5 into the trap b of the apparatus. At the same time washed effel and water flow into the funnel 1,

pass along the pipe 7 rotating around its axis and fall onto the semi-ball separator 9 attached to the mixer 8, from where they are picked up by oncoming water from the nozzles, under the influence of which they rush upwards together with the water cycle formed by the mixer 8.1

Water, running along the edges of the mixing vessel 10 together with the rock, forms a solid conical krator, and due to its rotational movement and jolts along the edge of the mixing vessel 10, as well as the pressure from the bottom of the water, through the nozzles 5, all particles of the rock with a low specific gravity it rises up and is carried away through a side opening regulated by a damper 22 along the chute 12. The metal particles, due to the large specific gravity to the bottom of the mixing vessel 13 through the water-thinned rock, and deposit on it, are no longer rising. and by virtue of the rotational motion they fall into specially arranged grooves 14, in which the metal goes down into a special trap b, in the center of which they are assembled thanks to the smallest

In it is the action of centrifugal force.

At the end of the rock supply, the operation of the apparatus and the water supply will continue until the chamber filled with rock is released through the existing opening 11 with the help of a damper 22 driven up and down by a screw 15; the damper is gradually lowered to the very bottom of the mixing chamber 13, which increases the opening of the rock outlet. The metal in catcher B is lowered through a special lock 16 into any vessel. At the very end of the operation, a part of the metal, which may be in the remaining sand at the bottom of the mixing chamber, is washed by the irrigation ring 17, located in the upper part of the chamber, by means of a valve 18, from where they fall through the trap into the substituted vessel. There is a collector 19 in the chute 12, which is used to avoid metal drift in the event of over-accelerated rotation of the broom. The contents of this collector are released by constipation 20 upon termination of the work of the entire apparatus, simultaneously with the release of the catcher 6.

The apparatus is set in motion by any transmission (chain, belt, etc.). For control, at the start of work, the doors 21 of the apparatus are closed with locks (or sealed) and open them upon termination of work to remove the precious metal.

The subject of the patent.

An apparatus with upward flow of water for collecting alluvial metals, characterized in that it is equipped for separating rock from metal with a mixing vessel 10 of a cylindrical frame with a conical bottom, to which a catching cylindrical shaped vessel 6 is riveted with a hole at the bottom for removing metal and has a half-cavity separator 9 and sdlku 8 (Fig. 1-4).
