    The invention relates to special machines which are used almost exclusively in the milling industry. With these machines, grains are sorted as far as possible in a large granulation range.
    The aim of the invention is to facilitate access to the large scale pots and maintain cleanliness.
    FIG. 1 shows a large general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the basic structure of a base with a stand and a casing for air exhaust; in fig. 4 shows the construction according to FIG. 3, supplemented by swinging elements; in fig. 5 is a schematic representation of a portion of the air exhaust housing corresponding to a single suction column in FIG. 6 - section BB on the League. five; in fig. 7 shows another embodiment of the assembly shown in FIG. five; in fig. 8 - the node shown in FIG. 7, top view; in fig. 9-10 are variants of the connection of the swinging elements of the close-up with the lever system; in fig. 11 is a diagram of various options for transferring force from the suction column to the tilting transport chute.
    Krupoveyka contains a base 1, above which two suction columns 2 with strainers 3 are arranged symmetrically with respect to its longitudinal axis. An end inlet 4 is provided for feeding into the sieve 3 of the initial product.
    dismountable particles. At least one unbalanced vibrator 5 serves as the base for oscillation of the screens.
    5 To receive sifted particles. Above the collectors, adjustable valves 8 are installed. Above the suction columns with the formation of symmetric with respect to the longitudinal axis of the base of the aspiration spaces 9, an air exhaust cover 10 is installed, having movable exhaust air valves 11 through the screens. Suction columns connected to base
    5 with shock-absorbing supports 12, and the casing 10 with supporting elements in the form of racks 13 installed at the longitudinal edges of the suction columns in the plane of symmetry of their location. Support 12 is installed on the base on both sides of the uprights. The device is equipped with a lever system with adjustable drive levers 14 and 15 associated with suction columns. Suction collecting channels 16 of the casing 10 are made with swirl chambers 17 at the entrance. Collections 6 and 7 have two drain holes 18 and 19. The direction of swing of the screen sieves can be adjusted by turning the unbalanced vibrator on the tubular transverse reinforcement 20. The intensity of the disturbing forces can be adjusted by adjusting the unbalance accordingly
    masses 21. In the case of fixing two unbalance vibrators on the transverse reinforcement, they are connected by an electrical

    so that they rotate in opposite directions, this compensates for the lateral components of the unbalance and makes absolutely longitudinal oscillations in the direction of the arrow 22. A cover 23 is located above the vibrators, which is made as part of the oscillating system. Under the troughs of the sit there is a swinging transport chute of 24 collections, which rests on each end side on one support (lever .15), embedded in rubber. The vibrating drive of the transport chute 24 is carried out by means of a lever 14 connecting the rocking end support 24 with the lever 15. Depending on the height at which the lever 14 is attached to the lever 15 (this height adjusts), the oscillation of the chute 24 can be adjusted regardless of the course of oscillation of the aspiration columns 2. Racks 13 go down at the bottom through the extension to the bottom of the rack. According to FIG. 2 pillar 13 protrudes slightly above the upper limit of the upper sieve rus. The aspiration spaces 9 have tapering forms and are divided along the entire length by the screens 26 into sixteen separate air-; conductive chambers 27. As shown in FIG. 5, the screens 26 extend to the upper screen, and the distance is chosen so that it is slightly larger than the maximum thickness of the product layer. The upper inclined surfaces of the housing 10 are provided along the entire length with transparent windows 28 (FIG. 2), so that using the source of electric light 29, the nature of the material flow under the upper screen flute can be monitored from the outside of the device. The adjustable valves 11 can also be adjusted by means of the button 30, taking into account the predetermined air flow.
    FIG. Figure 3 shows the basic structure of the non-tilting elements of the device, and in this figure two exemplary embodiments are shown. In one embodiment, an elastic or resilient element 31 is located between the base 1 and the leg 13. In another embodiment, the elastic or resilient element 32 is located between the leg 13 and the casing 10. In the first case, the leg 13 together with the casing
    10 forms a damping mass for non-pumping elements; in the second, only the case 10 forms a damping mass. It is also possible the implementation of the rack 13 in a lightweight design and in the form of an elastic element. Another embodiment is shown in FIG. 2 and 4. A bottom 33 is provided between the aspiration column 2 and the collectors 6, 7, which is oscillatingly supported on the base 1 and has a large number of recesses 34 along its entire length, the lower part of which can be guided by valves 8 to control the exhaust channels (Fig. 4) product to internal or external collection 6 or 7. Preferably, the number of valves 8 corresponds to the number of exhaust chambers 27. The working air flows through gaps 3 provided on both sides. In this case, the introduction of air is completely separated. Product removal from under the bottom 33 and the air flowing side facilitates deflection falling on the bottom 33 of the product towards its center, i.e. product concentration. The product flow is directed to the swinging transport chute 24 and is discharged through the openings 18 and 19.
    In addition, the product stream can to some extent self-purify. In known devices, valves 8 are installed directly on the trap device, as a result of which one half of it is blocked all the time, so that there are inaccessible places under it in which dirt accumulates. Another significant advantage is that the particles passed through the sieve can be very accurately divided into predetermined fractions, since there are no disruptive air flows in the longitudinal direction.
    When commissioning the grooves, the vibrator 5 is turned on, so that the suction columns 2, the bottom 33 and the collectors 6, 7 perform a predetermined oscillatory movement in the longitudinal direction, while using a vortex chamber 17 or the suction channel, a slight decrease in pressure in the device is achieved. Depending on the separation desired, all valves and
    gates Then you can feed the product through the end inlet 4. The product immediately enters the sieve Rus. Due to the vibratory movement of the product, the inclination of the screen wheels to the discharge for discharging particles and passing air through the screen wheels, the product behaves like a liquid. The main task of the cake is screening, which means that the air should not be so strong that the entire product layer rises from the screen beds, on the contrary, first of all, the air must loosen the product and evenly distribute it over the entire surface of the screens.
    Depending on the setting of the task, the product can be fractionated into large, medium and small grains, or into grains for cooking and medium grains, etc. In the second case, the first six valves 8 can be directed to one, and the next eleven to the other transport chute. In this case, the two sifted materials are target products. The product discharged from the sieve is partly re-milled or ground and fed to a second cake set appropriately.
    In each large box you should choose the appropriate size of the holes for the screens.
    A light is turned on to evaluate the mode of operation of the device, as well as the quantity and quality of the fractions obtained. Through the windows, one can observe the nature of the flow of the product in separate chambers 27 along the entire length. If in one or several chambers a state like boiling water is observed, then in these chambers the amount of air is reduced by means of valves 11. In places where the product accumulates, the amount of air is increased.
    Each of collections 6 and 7 has two different drain holes, which can optionally be used so that from each suction column to receive four different ftrits.
    Figs 7 and 8 show a preferred embodiment. Instead of re-adjustable valves 11, gate valves are used to provide more precise control of the air flow.

    Turning the button 30 causes a proportional change in the opening cross section. When using valve
    The living hole cross section does not change in proportion to the rotation of the button. The different position of the gate does not affect the living section of the suction collecting channel (vortex chamber).
    FIG. 9 shows the bearing of the swing assembly on the rubber hinge system 36, which is part of the spring system 37.
    15 The unbalance vibrator can be rotated around axis 20 so that the direction of action of forces 38 can be adjusted as desired, as indicated by arrow 39. If the direction of action of forces 38 passes through the center of gravity S of the swing assembly, a uniform sieve of the bag is achieved. If the direction of force 38 does not pass through the center of the plate S, then it is possible to adjust the true oscillation on the release according to the angle oi as needed, and on the inlet - according to the angle ft.
    30 FIG. 10 and 11 depict another embodiment. The suction column rests on a spring system 37 or a steel spring 40. The vibrator performs essentially absolute 35 ° C linear oscillatory motion (FIG. 9). The chute 24 rests with the possibility of oscillation independently of the aspiration column on the lever (support) 15. End support 12 connected
    40 with the lever 15 through the lever 14 so that the oscillatory movements of the unit, supported with the possibility of oscillation by the spring system 37, can be transmitted through the lever 14 to collections 6, 7. When
    45 this lever 14 can be fixed on the lever 15 at different heights x ,, x2, ..., x &. This makes it possible, due to the drive from the unbalance vibrator, to generate strong vibrations of oscillations of collections 6 and 7. The batch sieve body performs a short-term oscillatory motion for sifting, and the transport one - a long-term oscillatory-throwing motion.
