Description

The invention relates to devices for separating the moisture of lump material, in particular peat, and can be used in the mining, construction and other industries.

A device for sifting loose materials is known, comprising a screen with screens, hinged on the upper ball bearings of the uprights 1.

However, the known device is characterized by the impossibility of changing the angle of inclination of the box for sowing wet material on it.

Closest to the proposed technical essence and the achieved effect is a device that includes a rack with sieves mounted on the racks, a crank mechanism with a counterbalancing weight, a device for changing the inclination of the box and the drive 2.

This device is characterized by insufficient effectiveness of sifting wet material on it due to the impossibility of increasing the tilt angle of the screen box by more than 5 ° and adjusting the amplitude of the box oscillation.

The purpose of the invention is to ensure efficient sieving of wet material by optimizing the trajectory of the particles.

The goal is achieved by the fact that in a device for sieving wet bulk material, including a sieve box mounted on racks, a crank mechanism with a counterbalance weight, devices for changing the angle of the box and an actuator, the crank mechanism is equipped with a spherical support, while balancing the load and the crank movable in a horizontal direction.

FIG. 1 shows a device with a partial section, front view; in fig. 2 is a section A-A in FIG. one.

The device comprises a base 1 with two pairs of damping telescopic struts 2 and 3 of the same length, installed at different heights from the base 1 to create a tilt angle of the box in the direction of product flow.

Depreciation racks 2 and 3 are connected to the upper and lower ends by the use of the support 1 and the box 4 by means of elastic supports 5, thanks to which the operation of the device is smooth and silent.

Inside the box 4 there is a sieve b and a tray 7 for collecting the sifted product. The material is loaded through the loading nozzle 8, the separation products are unloaded through the nozzles 9 and 10. A cup 11 is attached to the lower part of the box 4 in the center for the spherical support 12 mounted on the trunnion 1h, which is integral with the crank 14. The crank 14 is fixedly mounted on the face plate 15, which is integral with the drive shaft 16, connected by means of a V-belt transmission 17 with a driving motor 18 mounted on the base 1.

The eccentricity value t, which characterizes the amplitude of the oscillatory movements of the duct 4, is provided by means of an adjusting screw 19.

To balance the oscillating masses of duct 4 on the faceplate 15 of the drive shaft 16, the counterweight weight 20 is mounted with an adjusting screw 21.

To set the angle of the box. 4 suspension struts 3 equipped with movable telescopic bar 22

5 with locking sleeves 23. Changing the frequency of oscillation of the box 4 is ensured by replacing the tongue 24.

The device works as follows.

Using the retractable rods 22 and the fitting sleeves 23, set the height of a pair of pillars 3. This causes a change in the angle of inclination of box 4 with a screen 6 relative to base I. When the angle of inclination changes, the spherical support 12 mounted in glass 11 slides along the pin 13 of the crankshaft 14 and self-aligning on the outer sphere inside the cup 11. After switching on the drive motor 18, the rotational movement is transmitted from the pulley 24 through the V-belt transmission 17 to the drive shaft 16 with the faceplate 15 to the crank 14 with the trunnion 13. Rotational the movement of the drive shaft 16 by means of the crank 14 with the trunnion 13 is converted into a circular motion and through the cup 11 the duct 4 communicates with the sieve 6. The depreciation struts 2 and 3 carrying the duct 4 sealed by their lower ends in the elastic supports 5 (points t) of the base 1 4, along with the duct, make circular motions around a vertical axis passing

0 through point t, forming a deflection angle characterizing the magnitude of the displacement of I box 4 with a sieve 6 in the horizontal plane. This provides the appearance of a vertical component h, which characterizes

j is the displacement of the duct 4 with the sieve 6 in the vertical plane.

The material supplied to the sieve 6 due to the influence of friction forces of its surface with the scattered material supplied to it communicates circular motion to the particles and due to its inclination informs the translational motion of the peat particles under the action of its mass from the loading nozzle 8 to the discharge 9 and 10.

As a result of the addition of circular and translational motion, the particles move along an elliptical path. The screened material through the sieve 6 is sent to the pallet 7 and from it enters the discharge nozzle 9. The lumpy material from the sieve 6 enters the nozzle 10.

With an increase in the angle of inclination of the duct, the particles of material move along the sieve 6 along an elongated elliptical trajectory, which. leads to a decrease in the productivity of the device due to the fact that the particles pass over a smaller number of screening cells of the sieve. To change the trajectory of movement of the particles of the material, the change in the 1 magnitude of the radius of the circular curvature of the curve 14 by moving

it in the horizontal direction and fixation by means of the screw 19. At the same time, in order to neutralize the imbalance resulting from this, the balancing weight 20 is moved by the screw 21.

The change in the eccentricity of the crankspaw placement ensures the movement of particles of the material along an optimal slightly elongated elliptical trajectory, which ensures an efficient sieving of the material with elevated humidity up to 50%.
