Abstract

The invention relates to a device for thickening the pulp before transporting it and cleaning the technological discharges of the beneficiation plants of mining enterprises. The purpose of the invention is to intensify the process of separating suspended particles from a liquid due to the uniform distribution of the flow of the original pulp over the entire area of the thickener, as well as improving the hydraulic parameters of collecting clarified water. The original pulp is introduced into the loading cup 10 by means of a tangentially feeding pipe 11, flows into the perforated disk 14. A part of the flow passes through the holes of the disk 14, another part, reflecting from the perforated disk 14, and then from the conical reflector 13, is directed upwards into the packets 4 parallel plates, where the deposition and integration of small fractions.

Description

1

The invention relates to devices for; - pulping prior to its transportation and cleaning of technological discharges from processing plants of mining enterprises.

The purpose of the invention is to intensify the process of separating suspended particles from / liquid by uniformly distributing the flow of the original pulp over the entire area of the thickener, as well as improving the hydraulic parameters of collecting clarified Yu water.

FIG. 1 shows a thickener, section A - A in FIG. 2; in fig. 2 shows a section B-B - D - D in FIG. one.

small vertical speed enters the packs of 4 parallel plates. In packets 4, the flow is divided into separate thin layers with a laminar flow regime, in which precipitation and coarsening of small fractions take place, into relatively large aggregates that fall out of the plate packs into the conical part 2 of the housing 1. Here they together with large particles fall to the conical bottom 2, they slide down its walls and through the discharge pipe 15 in the form of thickened pulp are removed from the thickener.

Clarified water is taken separately from each pack of 4 inclined

The vertical thickener contains quad-5 plates. The clarified water from the catchment area of the military corps 1 with a conical bottom 2, chambers 5, through the water outlets b and

plates is 45-60 °), catchment The proposed thickener provides

chambers 5 with drainage holes 6, 20 intensification of the separation process of suspension trays 7, a catchment collector 8, a discharge pipe 9, a loading cup 10 with a tangential inlet pipe 11 and perforated partitioned particles from the liquid due to uniform distribution of the initial pulp flow over the entire area of the thickener, improved hydraulic parameters and compressed 12, a conical reflector 13, the perforation of the system for collecting clarified water for

riated disk 14 and discharge pipe 15. Vertical thickener works as follows.

The original pulp is introduced into the loading cup 10 by means of a tangentially feeding pipe 11. As a result, a downward swirling flow is formed in the cup, the energy of which is quenched as it flows through the perforated partition 12, and a close to uniform flow distribution occurs throughout the loading cup 10. From the feed cup 10, the pulp enters the perforated disk 14, where the flow of pulp separates: a part of it passes through the holes of the perforated disk 14 into the lower zone of the conical bottom, the other part The stream, reflected from the perforated disk 14, and then from the conical reflector 13, is directed upwards, the flow around the loading cup 10 is obstructed, preventing the occurrence of circulation currents in the housing 1 and the conical bottom 2 of the thickener. In the thickener, a uniform upward flow is formed. At the same time, the fine fraction together with the fluid flow is directed upwards and with

by tilting the plates in opposite directions and dividing the body into two equal parts by a catchment collector.
