Anti-gravity three-phase separator

Abstract

The invention belongs to the technical field of separating devices, and discloses an anti-gravity three-phase separator. The problem that the separation effect of existing separating devices for separating graphite and diamond still needs to be improved in the prior art is solved. The anti-gravity three-phase separator comprises an upper section separation column, a middle section separation column and a lower section separation column, wherein the upper section separation column, the middle section separation column and the lower section separation column are connected from top to bottom andthe diameters of the upper section separation column, the middle section separation column and the lower section separation column decrease in sequence. A slurry inlet is formed in the top of the upper section separation column, a graphite powder overflow opening and a graphite coarse particle discharge outlet are formed in the positions, close to the top and bottom, of the outer wall of the uppersection separation column, and the graphite powder overflow opening and the graphite coarse particle discharge outlet are located at two sides of an axis of the upper section separation column. Two primary water inlets symmetrically formed in two sides of the axis of the middle section separation column are formed in the outer wall of the middle section separation column. The bottom of the lowersection separation column is closed, and diamond discharge opening and two secondary water inlets are separately formed in the positions, close to the bottom and at the bottom, of the outer wall of the lower section separation column, and the two secondary water inlets are symmetrically formed in two sides of the axis of the lower section separation column. The anti-gravity three-phase separator has a good separation effect on the graphite and the diamond.

Description

technical field [0001] The invention relates to a separator, in particular to an anti-gravity three-phase separator, and belongs to the technical field of separation devices. Background technique [0002] With the continuous improvement of construction technology and the higher requirements of processing technology, the requirements for cutting tools, especially knives, are also getting higher and higher, which leads to an increasing demand for diamonds. In order to meet the increasing requirements, man-made Diamond became the most effective solution. In the production process of synthetic diamond, after the diamond is synthesized, how to separate it from graphite becomes a key link affecting the whole process. [0003] The separation methods of graphite and diamond include chemical separation method and physical separation method. The chemical separation method is easy to destroy the original components in graphite and diamond, and the loss of diamond is large; the traditi...

Problems solved by technology

[0003] The separation methods of graphite and diamond include chemical separation method and physical separation method. The chemical separation method is easy to destroy the original components in graphite and diamond, and the loss of diamond is large; the traditional physical separation method generally uses shaking table screening, although it will not destroy graphite and diamond. The original composition in diamond, but the operation is troublesome and the separation effect is poor

The Chinese utility model patent with the publication number CN202021086U discloses a diamond and graphite vibration separator, which includes a linear reciprocating motion plate, a first water nozzle, a second water nozzle and a receiving box, and a grid is formed on the linear reciprocating motion plate. A first water tank and a second water tank are fixed on the rectilinear reciprocating motion plate, a filter screen is placed on the first water tank, a first water tap is arranged on the upper part of the filter screen, a first water outlet hole is evenly distributed on the left side of the first water tank, and a second water outlet hole is arranged on the second water tank. There are second water outlet holes evenly distributed on the left side of the water tank, the upper part of the second water tank is provided with a second water nozzle, and the lower part of the water outlet end of the linear reciprocating motion plate is placed with a receiving box. This device uses tap water to wash graphite and diamond mixed raw materials. The separation of diamond and graphite can be realized, but the device must use a large amount of water in the working process, the operating environment is full of ditches, and the environment is poor, and the separated graphite still contains a small amount of fine diamonds, and the separation effect still needs to be improved
