Description

 The invention relates to the field of mineral processing and may find application in the washing of gold and platinum sands.

 Known washing device for mineral processing, including a loading device, a chute with a roar and catching coating [1] A small product of sand enters the bottom, where there is an additional extraction of fine gold.

 The disadvantage of this washing device is the low efficiency of collecting fine gold due to the lack of the ability to effectively control the performance of the lower trough and the classification of sands into only two size classes. In addition, during the passage of the pulp stream from the upper trough to the lower direction of its movement, it changes to the opposite, which can lead to sewing of the head of the lower trough. For these reasons, the flushing device did not find wide application in the enrichment of placers.

Closest to the proposed one is a washing device for mineral processing, including a loading device, screens, sluices, collectors of sublattice products with exhaust holes, a concentrate rinse mechanism and concentrate collectors [2]
The disadvantage of this lock is the insufficiently high fine gold recovery due to the enrichment of fine-grained sands of broad size class at the locks, as well as the inability to control the hydrodynamic regimes of separation of mineral grains at fine-fill locks to optimize the beneficiation process.

 The aim of the invention is to increase the extraction of small grains of a valuable component and the performance of the washing device.

 The goal is achieved by the fact that the screens of the flushing device are installed one below the other and are interfaced with locks, while the loading device is paired with an upper screen.

The flushing device may be provided with additional gateways, the gateways are mounted on the longitudinal shaft with the possibility of changing their inclination from 2.5 to ^about 10, and kontsentratosborniki Brizgalov configured and installed under the gateways.

 The flushing device locks can be mounted on the transverse shafts with the possibility of changing the angle of inclination when turning relative to these shafts by means of a winch.

 Vibrators can be installed above the screens.

 The lower gateway can be made in the form of an endless moving belt, and can also be made with a vibrator.

 Collections of sublattice products through the diaphragm can be connected to cones having outlet openings, while the cones are equipped with vibrators.

 The side walls of the locks may have a rounded shape.

 Figure 1-5 shows a diagram of the washing device.

 The flushing device contains a loading device 1, screens 2, locks 3, collectors 4 of under-sieve products with exhaust openings 5, a mechanism 6 for rinsing the concentrate, concentrate collectors 7, trapping coatings 21.

The flushing device may be provided with additional gateways (fig.2,3) 8 mounted on the longitudinal shaft 9 under the upper gateways 3, pivotable through ¹⁸⁰ °, the shafts are arranged to change their inclination from 2.5 to 10 by means ^of lifting mechanisms 10. Under the additional locks 8 installed concentrate collectors 7 with spray 11.

 Gateways 3 can be installed on the transverse shafts 12 and equipped with a winch 13 (figure 5).

 Vibrators 14 can be installed above the screens.

 The lower gateway 15 can be made in the form of an endless moving belt, and can also be equipped with a vibrator 16. The collectors 4 of the sublattice products can be connected through the diaphragm 17 to the cones 18, while the cones 18 are made with vibrators 19.

 The side walls of the locks may have a rounded shape 20 (figure 4).

 The flushing device operates as follows.

The initial pulp is fed into the upper loading device 1. As it passes through the screen 2, the fine material is sifted and fed into the collector 4 of sublattice products, and the large material is fed to gateway 3 with a capture coating 21, where valuable components are concentrated. The rinsing of the concentrate is carried out by turning the gutter on the longitudinal shaft 9 by 180 ^about . In this case, the lower trough is replaced by the upper one, and from the lower trough, the concentrate is washed with water 11 by spraying 11 into the concentrate collector 7, which makes it possible to increase the washing device productivity by 10-15% and extract fine grains of valuable components by 8-9%
From under the lower roar, the pulp can enter the lower chute 15, made in the form of an endless flow of catching tape moving towards the flow, and the lower chute can be additionally equipped with a vibrator 16. As shown by the results of studies using mathematical models of enrichment processes, at a speed of movement of the tape from 0 up to 0.08 m / s fine gold recovery increases by 15-25%
The flushing of the concentrate can be carried out by lifting the far end of the gutter using a winch 13.

 The cones 18 with the vibrators 19 can be installed under the outlet 5 of the collection 4 of the sieve products. With the reciprocating movement of the cones, pulp ripples over the sieve, which improves the screening of the sands.

 Giving the side walls a rounded shape allows you to install gateways at a closer distance from each other.

 Thus, the use of the developed washing device allows to increase the extraction of fine grains of valuable components by 23-34% and productivity by 10-15%
