Description

This utility model relates to the field of concentrating devices for the hydroclassification of granular materials; it is used for mineral processing and the processing of industrial waste.

From the existing level of technology known step hydroclassification RU 2376068, publ. 12/20/2009, which is made according to a countercurrent scheme, but differs in the order of separation of the components of the mixture and fluid flow.

Closest to the claimed technical solution is patent RU 2166996, from which this utility model differs in that the lighter fraction is separated first, and then, subsequently, the heavier. In addition, the installation is made by a single functional device, in one technological building, in which separation occurs in a continuous upward flow of liquid (water). Another difference is the presence of a water recirculation system, which minimizes environmental pollution by products suspended in water, reduces consumption, and also allows the use of other process fluids with a higher or lower density.

The task to which the claimed utility model is directed is to expand technological capabilities and improve the quality of the shared products of the classification of materials, save water or other process fluid.

This problem is solved due to the fact that the claimed installation of hydroclassification of a mixture of granular and powder materials, consisting of vertically coaxially arranged cylindrical chambers (CCC), separated by cylindrical sorting, differentiating annular diaphragms, hydrobarriers, with systems for supplying liquid and removing finished classified products into the appropriate storage bins. The Central Control Commission combined in a single sealed enclosure. Separation of powder mixtures into fractions is carried out due to countercurrent flow of water from the bottom up, through hydrobarriers, starting from the lower CCC, and feeding the material from top to bottom, starting from the inlet funnel of the upper CCC. The rate of water rise is strictly standardized for each hydrobarrier and meets the classification conditions for the particles that make up the mixtures. Heavier particles pass through the hydrobarrier, lighter ones are discharged outside the upward flow and fall into the accumulation zone, from where they are discharged to the outside.

The hydroclassifier can be equipped with a microcontroller control unit.

The hydroclassifier can be equipped with a microcontroller control unit with interfaces for integration into ACS.

The hydroclassifier can be equipped with differential pressure gauges to measure the difference in interchamber pressure.

The hydroclassifier can be equipped with digital differential pressure gauges to measure the difference in interchamber pressure.

The hydroclassifier can be equipped with valves with an electric actuator to control the water pressure in the Central Control Commission.

The hydroclassifier can be equipped with solenoid valves to control the water pressure in the CCC.

The technical result provided by the given set of features is a preliminary gravitational separation of complex, granular, powdery mixtures into constituent groups of particles, their removal into the respective individual drives in terms of density and size. The principle of operation is the use of physical differences in the deposition rate of each of the constituent particles, their combination into groups according to similar characteristics, and subsequent, sequential, isolation in storage. Fractionation of mixtures by density.

The invention is illustrated by the drawing of FIG. 1, which shows a diagram of a hydroclassifier with particles of a mixture to be separated.

The hydroclassifier is a vertical system of communicating, through a special design separation diaphragm barriers, cylinder-conical chambers [1, 2, 3, 4] (CCC), located coaxially, one above the other, separated by cylindrical sorting, differentiating annular diaphragms-hydrobarriers [11 , 12, 13], with systems for supplying liquid and discharging finished classified products into appropriate bins

drives combined in one sealed enclosure. Consists of a common receiving unit - an inlet funnel [15], where the pulp line [16] receives a shared mixture in the form of pulp located in the upper part, devices for removing processed products from the CCC [5, 6, 7, 8] located on each The Central Control Commission separately, vertically coaxially, along the common body, the system for supplying the working fluid (water) [9.1], located at the bottom of the body. Also, a working fluid (water) is separately supplied to each CCC [9.2, 9.3], in order to maintain the constancy of the difference in the technological pressure and leaching (removing) finished products from the accumulation chambers [14] outside the CCC. The system for removing the heaviest products [10], represents an accumulating funnel located at the very bottom of the device and connected to a sealed receiving tank.

The device operates as follows. The separation of the components of the mixture products is based on the difference in the deposition rate of the constituent particles in the ascending laminar flow of liquid (water) formed by interchamber annular barriers - diaphragms. The flow rate of water, from bottom to top, is strictly normalized for each barrier, uniformly decreases from lower to upper and can be controlled by changing the pressure difference between the chambers. The barriers are located concentrically one above the other, one at each level (for each CCC). When particles pass through each barrier, relatively lighter brakes, or stops, becomes suspended, freezes and “boils,” as it were, while new particles coming from the center of the cone diaphragm the barrier, forcing “boiling” particles to move to the edges of the barrier to the outer part of the upward flow, where they fall into the excretion zone, outside the annular barriers, then they are carried out by the extraction system to the outside, fall to the bottom of the storage chambers, are taken out of the housing and enter the corresponding bunkers, it will accumulate whether repulpatory. At the same time, a sequential step-by-step subtraction of lighter particles from the mixture is carried out, heavier freely pass the upper barriers, but are delayed by the lower ones, each according to their individual physical characteristics, grouped by the deposition rate. After removal, particles with a stream of water are discharged into the tanks of the settling tanks, from where the process liquid (water) is returned by pumps to the system for supplying working fluid (water). The main requirement for this system is the maintenance of the necessary technological pressure of the working fluid (water) in all the central control centers.
