SU1503882A1 - Apparatus for discharging sands from deslimer - Google Patents

Abstract

This invention relates to the beneficiation of minerals. The goal is to reduce metal losses with tails and increase reliability. The device contains a discharge pipe / PT / 1, in the lower part of which there is an outlet device in the form of a conical locking element 2. The latter has a hole 3 in the center and is installed with a top under PT1 and coaxially with the possibility of adjustable overlap of the cross section PT 1. Element 2 can be Reinforced with a special coating. Through hole 3, material is continuously withdrawn. At the same time, the volume of discharge through the hole is significantly less than the volume of the solid entering the declarator. 1 il.

The invention relates to enrichment and can be used in the declaring of finely divided materials in the mining, coal, chemical and other industrial fields.

The purpose of the invention is to reduce the loss of metal with tails and increase reliability of operation.

The drawing shows a device for p. Loading sands of a declarator.

The device for unloading sands of the declarer includes a discharge pipe 1, in the lower part of which there is an outlet device in the form of a conical locking element 2, in the center of which there is an opening 3, a support rod 4, a lever 5, a support bearing 6, counter loads 7 and a valve 8. the element 2 is installed with its top up under the discharge pipe 1 and coaxially with it with the possibility of a regulated overlap of the cross section of the discharge pipe 1.

The device works in the following way.

Valve 8 is opened on pipe 1, making it possible for the dried material (e.g., magnetite concentrate) to drain from the bath of the waste separator. Through the opening 3 in the locking element 2, the condensed material is continuously withdrawn. At the same time, the outflow volumes through the opening 3 are significantly less than the volumes of the solid entering the declarator (the flow in the drawing is indicated by arrows A). This creates conditions for the accumulation of material in the bath of the separator and its compaction. Having reached a given density, experimentally established for specific conditions, element 2, pivotally connected to the lever 5, opens, overcoming the pressure of the counter-loads 7, and releases higher volumes of condensed material (flow in the drawing is indicated by arrows B), which leads to a decrease in its density, and

item 2 closes. The rotation of the lever 5, on which the cone valve is attached with the help of the rod 4 and mounted on the cone valve and the counter-loads 7 are mounted, is carried out on the fixed bearing 6.

In the device, element 2 can be

strengthened with a special coating that will determine its operation with long turnaround time with high operational reliability.
