Closest to the claimed solution to the technical essence and the achieved technical result is multilayered separator for wet gravity separation of ores by author. St. USSR N 1044331, publ. 30.09.83, M. CL.303 In 5/38 containing sequentially arranged along the vertical axis of the feeder and connected by a pipeline first and at least second tier separation, each of which consists of polyparaphenylenes, working surface made in the form of inverted truncated kolichestvennoi or pyramid surface, and a discharge valve with a shut-off valve, and the discharge node includes a first output for a first heavy fraction, a second outlet for the light fraction, while the outputs of the discharge valve of the first tier connect the points of separation in series tiers pereymayutsya, this heavy fraction from the first output discharge node of the first tier is supplied to the cleaners at the entrance of polyparaphenylenes the sixth layer, and the light fraction from the second output discharge node of the first tier to the input of polyparaphenylenes the second tier for re-enrichment, light fraction from the second output of the discharge valve of the second tier to the input of polyparaphenylenes third tier, the light fraction from the second output of the discharge valve of the third tier to the input of polyparaphenylenes fourth tier, light fraction from the second output of the discharge valve of the fourth tier is removed from the separator, while the heavy fraction from the first outputs of the discharge of second nodes, the third and fourth tiers to the input of polyparaphenylenes fifth tier, heavy fraction from the first output discharge node of the fifth and first tier is fed to the input of polyparaphenylenes sixth tier, with the first discharge valve which is heavy fraction from the separator, while the light fraction from the second output of the discharge valve of the sixth layer is mixed with the heavy fraction from the first output discharge node of the fifth stage and out of the separator in the form of the working surfaces of the lower tiers of the separator, due to the fact that after separation occurred on the upper tiers of the flow of the pulp coming from the working surface of the bottom layer is thinning, and this leads to low efficiency of the separator. In addition, the sequential separation by tier one operation is performed on the same tier that necessitates the use of a large number of layers.

The basis of the invention is the creation of an effective multi-tiered separator for wet gravity separation of ores by the radial separation of the working surfaces of the layers in the form of sectors of separation that ensures their full load on all tiers, including the bottom, and thereby provides a more efficient process of separating from them. And it also allows to reduce the number of tiers of the separator while maintaining the quality of separation.

The problem is solved in that the multilayered separator for wet gravity separation of ores containing sequentially arranged along the vertical axis of the feeder and connected by a pipeline first and at least second tier separation, each of which consists of polyparaphenylenes, R is ness, and discharge valve with a shut-off valve, and the discharge node includes a first output for a first heavy fraction, a second outlet for the light fraction, while the outputs of the discharge valve of the first tier connected with polyparaphenylene the second tier, and starting from the second tier corresponding polyparaphenylene working surface and the cutter unloading site mainly divided by radial partitions respectively on the first, second parts, the first output discharge node of the first tier is connected to the input of the first part of polyparaphenylenes second layer with a second input of which is coupled to the second output discharge node of the first tier, since the second tier of the discharge node contains an additional third output of the first intermediate product. However, starting from the second tier, in discharging the first output node is output to the heavy fraction from the first part of the cutter, a second outlet for the light fraction from the second part of the cutter, the third exit - for the first intermediate product of the light fraction of the first part of the cutter and the heavy fraction from the second part of the cutter. The separator also holds the third and fourth tiers of separation, while the first is a, with the second input part which is connected to the third output of the discharge valve of the second tier, and the second exit discharge node of the second tier and the second output discharge node of the third tier is connected to the input of the second part of polyparaphenylenes the fourth stage, the first input of which is connected with the third output of the discharge valve of the third tier, while the first discharge node of the third tier is connected to the first output of the discharge valve of the fourth stage is the release of heavy fractions of the separator, and the second and third outputs of the discharge valve of the fourth stage are the outputs, respectively, for the light fraction and the intermediate separator. And with each subsequent tier square of the first parts of polyparaphenylene, work surfaces and cut off the appropriate handling of nodes decreases, and the area of the respective second parts increase. In addition, in the last tier separation, starting from the third tier, polyparaphenylene working surface and the cutter unloading site mainly divided by radial partitions on the third part, and its discharge node has fourth and fifth outputs, and a fourth output, which is conducted by the output of the second intermediate product, the fifth release for the second heavy fraction from the third part of the cutter, while in the penultimate tier separation, starting from the second tier, the first, second and third outputs discharge valve connected to respective inputs of the first and third parts of polyparaphenylenes the last tier.

The separation of the radial partitions of polyparaphenylenes, work surface and cut off the discharge of the node in tiers, starting with the second, the first, the second part in the form of separate sectors of separation and the corresponding connection to the outputs of the first tier provides full load on all tiers, including the bottom, and thereby provide a more efficient process for separation of fractions by quality control peredishki the lower parts of the separator of heavy and light fractions and the intermediate product, is highlighted in the upper tiers. This is because when more than full load, the bottom layer increases the thickness of the flow of pulp on them and the quality of separation becomes the same as the upper tiers. This partition can be made strictly radial and curved, but providing mainly radial movement of the flow of pulp. The first, the second product after each layer separation. In addition, this embodiment of the separator provides a significant reduction in the number of tiers in the equivalent as of the separation.

Execution, starting from the second tier, in discharging the first output node of the first part of the cutter, a second exit from the second part of the cutter and the third output is the output connection for the light fraction from the first part and the outlet for the heavy fraction from the second part of the web clipper allows you to provide for each subsequent tier of simultaneous and separate the two cleaners products separation of the three (heavy and light fraction and an intermediate product) of the previous tiers to fill the working surfaces of the lower tiers.

Execution of the separator with the third and fourth tiers of separation in the sectoral division of the flow of pulp provides high-quality separation with optimal number of tiers.

The location of the radial partitions so that each subsequent layer of the first part (sector) of polyparaphenylene, work surfaces and cut off the discharge of the nodes is performed on the area less than the area of the first parts of the previous tiers and proper execution of the second parts einem tier, because in the process of separation of the heavy fraction stream with each subsequent layer is reduced and the light fraction and the intermediate product is increased.

The division in the last tier separator radial partitions polyparaphenylenes, work surface and cut off the discharge of the node on the first, second and third part (sector) provides five outputs in the discharge end node of the last stage and thus to produce a final cleaning out pulpotomy emitting not three, but five products separation: the first and the second heavy fraction light fraction and the first and second intermediate product. And this improves the yield of the final product separation by grade.

The above confirms the presence of causal relations between a set of essential features of the claimed invention and achievable technical result.

This set of essential features allows comparison with the prototype to ensure a full load of working surfaces on all tiers of the separator, including on the lower tiers, and thereby provide a more efficient separation process of pulpotomy into fractions. In addition, allows umei at the outlet of the separator five species of the grade of the final product in the form of two heavy fractions, one light fraction and two intermediate products.
