SU1518011A1 - Hydraulic classifier - Google Patents

Abstract

This invention relates to a hydraulic classification for the size and density of powdered materials in the mining, construction, and other industries. The goal is to increase the efficiency of material classification according to the calculated boundary grain and specific production. The classifier includes a series of consecutively installed chambers / K / 1.2 and an additional K 28. The first K 1.2 is made in the form of 3 prisms of rectangular section inclined towards the loading device. They consist of lagging walls 8.9 on the side of the loading device 3 and a smooth wall 10 on the side of the overflow threshold. A continuation of the inclined ledges of the tilted walls 8.9 are pouring shelves / PP / 6. In the upper part of PP 6 there are openings and nozzles for the discharge of gases evolving from water. Under PP 6 there are additional pipes 17 for supplying water. In the lower part of K 1.2 there are also water inlets. Parallel to the wall 10, a partition 19 is installed, having windows 20 and canopies. A rotary wheel 34 is installed in the receiving pocket of the 29 K 28. In the classification compartment 30, the precipitating plates / П / 41 are installed, and at their lower end are U-shaped dividing boxes-shelters 42. Under the П 41 with a gap to them and perpendicular to them accelerating П 40. At the upper end of К 28 a tilt angle changing mechanism is installed, kinematically installed with П 41. The material is fed into the device 3, and water is fed from the pipes 7, 17. The material is poured in PP 6. Fine particles are transported through windows 20 by water streams and enter K 2 through drain threshold 5. Large particles are discharged through discharge device 4. The process of classification in K 2 is similar. The material entering K 28 spins the rotor wheel 34 associated with an unbalanced cleaning wheel P 41. Classification occurs in the channels between P 41, the thin class is removed through the drain threshold 33, and the large by cover boxes 42 collapses siphon discharge device 32. 1C. f-ly, 10 ill.

in the upper pouring shelf, it is located above the overflow threshold 5 of the chamber 1 and communicates with the atmosphere.

Under the pour-off shelves 6 there are installed additional pipes 17 embedded in the outer surface of the slanted walls 8, 9 for supplying water. To avoid clogging of the additional pipe 17 with a solid hole in the wall, it is covered with an additional visor 18, made in the form of a partition parallel to the vertical wall 9, connected at the top with a bridge with this wall, and on the sides with the side walls 13 of the chamber. At the bottom, the visor 18 is not in contact with the lower ledge 8. A parallel city wall is installed parallel to the smooth wall 10. 19 with windows 20 and upwards toward the smooth wall canopies connected to the lower walls of the windows. The dividing wall 19 abuts against the side walls 13 and divides the chamber into descending 21 and ascending 22 channels. The upper edge of the partition 19 is located above the drain threshold of the chamber, and the lower edge is at the level of the lower edge of the lower pouring shelf 6 Okia 20 in the partition 19, preferably the straight, 1 st section, flush with the lower end of the pouring shelves 6.

The number of windows 20 in the partition 19 is equal to the number of the pouring shelves 6. The number of the latter and the distance between them is determined by the particle size distribution of the material and the task. A sufficient number of pouring shelves 6 is 3 4 pieces.

The cross section of the window in the partition should be such that it freely misses the estimated amount of pulp. Drilling a window with a section of the tub than necessary will result in a violation of the laminar movement of the suspension in the downward and upward flows.

The lower part of the chamber, connected to the middle with the help of a truncated inverted pyramid, is made in the form of two coaxially arranged cylinders 23 and 24, interconnected at the top by a blind jumper 25. The outer cylinder 23 ends with a conical bottom 26 with a hole along the central axis, and the inner cylinder 24 the lower edge does not touch the perimeter of the conical bottom 26. In the lower part of the chambers there are water inlets. They are embedded in the upper part of the outer cylinder 23 and through them into the space between the cylinders 23, 24 the calculated amount of wash water is supplied to create an upward flow in the cylindrical part of the chamber.

The release of gases from the space between the inner and outer cylinders is carried out periodically through a pipe with a valve 27, embedded into the upper part of the outer cylinder.

and frame-tg 49. The imposition of vibration on the precipitation plates 41 improves the transport of axial, x particles through them. This also reduces the critical angle.

the inclination of the plates, and consequently, decrease the effective deposition area and thus increase the specific capacity of the apparatus for the same dimensions; Calming plates 40 in the bunker compartment 31 of the chamber are installed under the settling 41 vertically and perpendicular to them with a gap. The designation of soothing plates is the suppression of the turbulent motion of the incoming puls. A gap between the settling and sedative plates is necessary in order to be able to rotate the settling plates 41 at the required angle.

The proposed hydroclassifier allows the classification of virtually any material composition of solid materials. The number of chambers in the classifier is determined by the grain composition of the initial material and the number of size classes into which this material should be divided. To classify crushed to a size of 2 (3) -O mm of quartz raw material, it is sufficient to set up two similar chambers to obtain classes with sizes of | -0.4 and 0.4 | -0.1 mm and one add. camera for class separation

0.14-0 mm in the boundary grain 0.01 0.02 mm.

Hydroclassifier acts as follows.

When starting, in the first and last chambers, the plank gates 58 overlap. Through the pipes 17 and 7, the calculated amount of wash water is supplied under i |) e- sypnyi fluids 6 and into the cylinders 23, 24. Then the suspension is fed into the loading device 3 of the first chamber . Drainage of the first chamber is the power supply of the latter, p.1 and the second - additional power. After filling the first and last chambers with the pulp, they are ready for operation; they open the hose gates 58 and put the air-lift unloading devices into operation 4. The unloading device of the auxiliary chamber is put into operation automatically. The angle of inclination of the settling plates 41 depends on the nature of the deposited material.

The suspension supplied to the loading device of the first chamber enters the inclined bottom 14 into the descending channel 21. At the moment of transfer of solid particles from the lined shelf 6 to the lower position (.) The removal of the washing water from the shelf of the calculated hours of the particles from the descent 21 to the ascending 22 through the windows 20 in the partition 19. Particles of the design class, not carried out through the windows 20 in the partition 19 into the upward channel, enter the cylindrical part of the chamber, where the final dissociation of the particles by size occurs. . The class is larger than calculated through the hole in the conical bottom 26
