Description

The invention relates to a device for the enrichment of gold concentrates.

Known gateway containing metal stencils, under which are laid rubber or wicker mats (in the form of rugs made of corrugated rubber, cloth) (Polkin S.I. "Enrichment of ores and placers of rare and noble metals." M. Nedra, pp. 346-349 ).

The disadvantage of the concentrating sluice is that the device of stencils, and under them rubber mats, do not provide sufficient complete extraction of precious metals due to the lack of movement at the bottom of the sluice. The closest are the gateway of the washer according to the patent (see RU 2016144878 A, 05/15/2018, B03B 5/70,)

A known sluice for enrichment of sands, containing a bottom with sides and catching sills in the form of transverse plates, located above the catching sills, butorku connected to the drive of oscillations through a rotary pipe by rods and made of longitudinal plates with gaps for catching sills, made with the possibility of raking, raking material in the sluice, posts at the edge of the sluice on which a traverse with an oscillation drive and movable cables, the ends of which are connected to the butorka, is laid on top.

The disadvantage of the prototype is the complexity of removing the mesh and layout after removing the product.

The task of the proposed device is to increase the productivity of washing productive sands and extract fine-dispersed parts of precious metal at low and low content.

The technical result is to increase productivity and achieve a more complete extraction of precious metals.

This technical advantage is achieved due to the fact that the sluice for the enrichment of sands consists of an inclined bottom with sides and open from the rear part of the catching elements in the form of solid sills, fixed on the bottom of the oscillation drive of the sprinkler.

It differs in that the proposed sluice with laminar movement, under the bottom of which a tubular support is wound up with the calculation of changing the angle of its inclination using a mechanism.

On the bottom with the sides, catching sills are fixed, in front of which grooves are made on the loading side. Between the catching sills, rubber mats are laid rigidly attached to the bottom, and covered with a mesh, located above the catching elements, the butorku, connected to the vibration drive through the swivel pipe by rods, consists of several sections, hingedly connected to each other, each section is assembled from metal plates and fastened to each other transverse bridges, which are also catching elements, and the longitudinal plates are made with the possibility of raking the material in the sluice, gaps are made on each longitudinal plate. Above the catching sills, teeth are fixed to the plates, the ends of which are buried in the grooves. On the unloading side of the sluice, a temporary container is mounted with sides with a bottom, at the bottom of which a lifting gate is installed, along which they are fastened with one end of a cable. Above the temporary capacity, a rotary crossbar is installed, with which the second ends of the cables of the lifting gate are connected with a drive frequency. When turned on, the gate goes into automatic operation mode and keeps the pulp in the sluice according to the level. Racks on the edge of the sluice, on which a traverse with a drive and movable cables, the ends of which are connected with a butorka, is laid on top.

The lock consists of a bottom 1 with sides 2, is installed obliquely and equipped with a mechanism 3 for changing its angle of inclination.

A tubular support 4 is installed under the bottom of the lock 1 with the calculation of changing the angle of its inclination. On the bottom 1 of the sluice are fixed catching sills 5, in front of which grooves 6 are made, rubber mats 7 are laid between the catching sills 5 and rigidly fastened to the bottom 1. Located above the catching sills 5 butorka 8, connected to the drive 9 of horizontal vibration through a rotary pipe 10 with rods 11, consists of several sections, 12 pivotally connected to each other, each section is mounted from longitudinal metal plates 13, interconnected by transverse bridges 14, which are also catching elements. Longitudinal plates 13 are made with the possibility of raking the pulp raking along the bottom 1 of the sluice, on each longitudinal plate 13 of the butorka 8 there are gaps 15 under the catching sills, to each longitudinal plate 13 of the butorki 8 are attached loosening teeth 16 whose ends are buried in the grooves 6. On the unloading side of the sluice a temporary tank with sides 17 was mounted by a lifting gate 18 with a drive frequency 19, a rotary bar 20 was installed on top of the temporary container along which a cable 21 was attached, which were connected with a lifting gate 18 and with a rotary bar 20. Racks 25 at the edge of the lock on which a traverse was laid on top 24 with a drive 22 and movable cables 26, the ends of which are connected to the butork 8.

The sand enrichment sluice works as follows, the required working angle of inclination of the bottom 1 is installed using the mechanism 3. The incoming raw material from the device to the sluice, in the form of pulp, moves in a laminar mode. Include the drive 9 butorka 8 horizontal vibration, which captures the longitudinal plates 13 pulp, rakes and rakes along the bottom 1.

The pulp moves diagonally between the plates due to the slope and vibration of the butork 8 and a slight laminar movement, the smallest dust-like particles of precious metal, having no significant resistance, fall through the mesh 23 and settle in the cells present on the rubber mats 7 of deep or shallow accumulation, larger the particles of the heavy fraction move diagonally to the continuous catching grooves 6 of the sills 5, where the teeth 16 perform constant loosening. As the heavy fractions are filled, the light fractions are displaced from the grooves 6 and are rolled over through the catching sills 5 and leave with the water flow towards the unloading side. During a bad defrost or low water along the channel, the drive frequency 19 is switched on, the gate 18 switches to automatic control mode. Now the tailings from the sluice come off without reducing the volume of the slurry through the sluice, which improves the quality of the precious metal washing and sedimentation. When the heavy fraction (concentrates) is collected enough, the material feed is stopped. Mechanism 3 changes the angle of inclination to a horizontal position. They turn on clean water, rinse the product on the rugs 7 with grooves 6. Stop the butork 8, fold back the rods 11, turn off the water supply, turn on the drive 22 due to the rotation of the traverse 24, the cables 26 are wound on the traverse 24, the boot 8 rises to a vertical position. Removal begins from the bottom 1 of the sluice with a converted vacuum cleaner, which, with the help of suction from the groove 6 of the mats 7, draws the concentrate into the container. The sluice is now ready to process the next batch of material.

The greatest difficulty in enrichment of gold placers is the extraction of fine dust-like lamellar fractions of metal, the fault of which is the turbulent movement of the pulp through the sluice, the proposed sluice with laminar movement will raise these losses.
