Description

one

The invention relates to the mining industry and can be used for the separation of bulk materials by size with simultaneous clarification of the water used by the wound process.

A hydroclassifier for granular materials is known, comprising a housing with separator pockets located in its lower part, which are integrated with the classifying chambers, adjustable mesh valves and a feed inlet, to the upper edge of which a screen is attached, and the housing is mounted on hinge isometric supports, equipped with regulating devices for measuring their height, and the classifying chambers are also mounted on hinges, and the filtering water inlet pipe SL 1Nedos is built into the side wall of the last pocket. A known device for separating granular materials is the low classification accuracy due to the separation of material by size in a turbulent flow.

The closest in technical essence and the achieved result to the invention is a device for separating granular materials and water clarification, including a housing with dividing pockets, receiving | special camera, classification chambers, lamination of fixtures made from a bag (plate, fixtures for entering the material and putting the finished separation products 2 J.

The disadvantage of this device is the insufficiently high efficiency of the separation process, as a result of which all waste (clay particles and nvc and ionic fractions) are removed into the discharge together with the waste water, which further must be deposited in special structures, in addition, clarification, water. The aim of the invention is to increase the efficiency of the separation process either by laminating the flow and increasing the degree of clarification of the water. This goal is achieved by the fact that a device for separating granular materials and water clarification, including a housing with dividing pockets, a receiving and distributing chamber, classification chambers, la minisation devices, devices for introducing material and withdrawal of separation products, is equipped with a water clarification chamber installed above. reception and distribution chamber, louvers installed in the reception and distribution chamber, and conduits, while laminating devices are installed obliquely in the cells aspiration chambers and in the clarification chamber. FIG. 1 shows a device; a longitudinal section; in fig. 2 - section L-L on (LP, 1; in Fig. 3, section B-B in FIG. 1. A device for separating grain-i nous materials consists of body 1 with receiver-spacer (stationary chamber 2, classification chambers 3 and the clarification chamber k, in which I install inclined plates 5 that form the gap-like channels 6. Underneath the hull are separation pockets 7 waste bins 8, unloading devices E, upflow channels 1 (1 with valve 11. In the upper part of the hull there is an inlet The connecting pipe 12 with the air separator 13 drain l a current 14 with a drain pipe I louvers 16 with a drive 17. The device works as follows: The slurry through the connecting pipe 12 through the air separator 13 enters the receiving-distribution chamber 2. In the process of movement along the receiving-distribution chamber 2 the flow rushes into the classification chambers 3 Along the slit-like channels 6 between the plates 5 B. Classification chambers 3 through the conduit of the upstream flow 1P supply an additional volume of water. Moreover, in the first chamber, the highest vertical velocities are created, in the second — somewhat lower, and in the third — even less, and so on, in connection with which, in the first chamber, the largest material, whose hydraulic size exceeds the speed of the upstream in this chamber, in the second - smaller, etc. The thinnest material, which in most cases represents production waste, falls in the last chamber, into which no additional hearth is fed. The slides along the walls of the choleric channels of the classification chambers, the material larger than a given size for this chamber falls into the separation pockets 7, and from the last chamber into the waste bin 8 where it accumulates From the separation pockets 7 and the waste bin 8, material and waste are periodically or continuously removed through unloading devices 9. The main flow of water with the thinnest particles from the receiving-distribution chamber 2 and classification chambers 3 enters the clarification chamber k, where, coagulated, the particles slide along the walls s and eventually deposited in the waste bin 8. The clarified water from the clarification chamber k falls into the drain tray 14 and through the drain pipe 15 is discharged from the apparatus. The water flow for the creation of the upstream in the classification chambers is controlled by means of the) louvers 16, driven by the mechanism 17, and also changed by the valves 11 installed on the conduits 10. By using the proposed device, the water consumption for Araktsi separation is reduced. the separation accuracy of the material in the laminar flow is increased.
