Description

The utility model relates to devices for separating a falling mixture of particles of solid materials using air flows and can be used in agriculture for air separation and purification of seeds of various types of crops in the preparation of commercial and sowing material.
A device for separating a granular mixture in a fluid according to the patent of the Russian Federation No. 2270061 (IPC: B07B 4/02, B07B 7/01, claimed on December 4, 2003, published on February 20, 2006) is known that is closest to the one proposed according to the set of features. The specified device contains a hopper with a vibratory tray, a centrifugal fan with an air duct and a pressure equalizing throttle and a nozzle grate with flat nozzles of various calibers installed in series with the flow with increasing nozzle gauge, their step, the length of the walls of the guide channels and the acute angle of the walls of the guide channels of the nozzles to the plane of the nozzle lattice, and collectors of finished and repeated fractions located under the nozzles and separated by vertical partitions. The role of the pressure equalizing throttle is performed by three sieves installed in series in front of the nozzles. Particles of the separated material are separated into fractions by a cascade of plane air jets with different flow rates. A turbulent zone arises at the interface between the jets, during the passage of which particles of separated material are blown by air jets from different sides,
begin to rotate, which averages their aerodynamic drag. The disadvantage of this device is its unsatisfactory work with a material whose particles have a pronounced irregular shape (rye, sunflower, barley seeds, etc.), which indicates a weak twisting effect of turbulent zones between the jets. In addition, the static position of the fraction collectors does not allow the device to be set up in order to obtain a given quality and percentage of the material by fractions.
The objective of this technical solution is to expand the boundary turbulent zone of the air flow between the jets, increase its intensity, which will lead to a significant increase in the frequency of rotation of the particles, as well as the randomness of their rotation, i.e. rate of change of position of the instantaneous axis of rotation of the particle in space. In this case, the average aerodynamic drag of a particle, even of a pronounced irregular shape, approaches the resistance of a ball of the corresponding mass and size, which ensures the identical influence of the aerodynamic force on particles that are close in their physical characteristics regardless of their geometric shape.
This problem is solved by the fact that in a device for separating a granular mixture in a fluid containing a hopper with a vibratory tray, a centrifugal fan, an air duct with a pressure equalizing throttle and a nozzle grill with flat nozzles of different calibers, installed in series with the flow from the top to bottom of the nozzle caliber step and acute angle of inclination of the walls of the guide channels to the plane of the nozzle lattice, and fraction collectors located under the nozzles and separated by partitions, place in the guide channel of each nozzle an air flow turbulizer, and separating separators of fraction fractions of the partition are pivotally mounted with the possibility of rotation around horizontal axes.
Placing a turbulator in the guide channel initiates the formation of an initial vortex in it, the development of which significantly increases the degree of turbulence of the outflowing jet in the working chamber. The hinged installation of separating fraction collectors of partitions allows you to change the position and area of fraction collectors, which provides the ability to control the quality and percentage of recycled material in fraction collectors.
The essence of the proposed technical solution is illustrated by drawings, which schematically depict: figure 1 is a vertical section of a device for separating a granular mixture in a fluid medium, figure 2 is a nozzle of the device, figure 3 is a collection of fractions.
A device for separating a granular mixture in a fluid medium contains a working chamber 1, a hopper 2 for accumulating and controlled supply of source material, a vibratory tray 3 for uniform distribution of the source material across the width of the working chamber 1 and ensuring a constant initial feed rate, centrifugal fan 4, duct 5, throttle 6, equalizing the pressure of the air flow in front of the nozzle grill 7, flat nozzles 8 variable and increasing from top to bottom in caliber and pitch. The walls 9 of the guide channels of the nozzles 8 are installed at an acute angle to the plane of the nozzle lattice, and the angle of inclination increases from top to bottom. In the guide channel of each nozzle 8 placed turbulators 10, providing separation of the boundary layer of air flow from the walls 9 of the channel. The turbulator 10 is made, for example, in the form of a tide or stamping channel rising above the plane of the wall 9, for example, of a rectangular cross section, parallel to the edge of the wall 9 at a distance from the nozzle grill 7, which is 15-20% of the length of the generatrix wall 9. In the working chamber 1 are placed collectors of fractions 11, divided by partitions 12,
pivotally mounted with the possibility of their rotation around the horizontal axes 13. The last in the stream collection of fractions 11 is made wider than the rest of the collections.
A device for separating a granular mixture in a fluid medium operates as follows. Before starting work in the hopper 2 load the source material. Turn on the fan 4, and air through the throttle 6 is fed to the nozzle grill 7, where the nozzles 8 are divided into jets of different speeds and directions. Moreover, in the area of contact of the air flows emanating at different speeds from adjacent nozzles 8, a turbulent layer is formed. The formation of the initial vortex in the guide channel of the nozzle 8 due to separation of the boundary layer of the air flow by the turbulator 10 from the channel wall 9 increases the degree of turbulence of the boundary layer in the working chamber 1, expands its zone. Then open the shutter (not shown) of the hopper 2, and the source material enters the vibrating tray 3, from which it is supplied with a constant initial speed to the working chamber 1. Particles of the source material, passing alternately the regions formed by the nozzles 8 of the air flows and the boundary layers between them, in the latter driven by a stream with a high degree of turbulence and randomly rotated with a high frequency. In this case, the average aerodynamic drag of rotating particles with the same characteristics of mass, geometric shape and surface state is the same, as a result of which they move along close paths and fall into the corresponding fraction collector 11. By changing the position of the separation wall 12 by rotating it around axis 13, the position of the fraction collector is adjusted and the area of its receiving hole, which increases the accuracy of getting into this collection of particles with specified characteristics.
The specified technical solution allows not only to carry out a qualitative separation of the source material according to the mass,
geometric shape and surface condition, but also to isolate various weedy difficult to separate impurities by searching and localizing their position in the space of the working chamber of the device. Due to a more accurate separation of the mixture, the productivity of the device increases by 40-50%.
