    2. The device according to claim 1, characterized in that it is provided with additional nozzles for supplying air and vaulted screens arranged sequentially behind the main sieve and interconnected by means of an obliquely installed transport channel, and the vaulted screens are zigzagged.
    3. The device according to claim 1, characterized in that the transport channel at the lower end is provided with a nozzle for supplying air
    in the direction of flow of the processed mixture,
    4. The device according to claim 1, which is equipped with a sound-insulating casing with a pipe for air release, located in its upper part.
    The invention relates to devices for dewatering and drying solids, in particular synthetic granulated substances under water in the form of a mixture of water with a granulate on a vaulted sieve using air flow, which passes both in the direction of water passing through the sieve and along it, water from the granulate is supplied to the vaulted sieve through the supply channel, and air is swirled through the vaulted sieve due to the energy of the flow through the vaulted sieve and at the end of the vaulted sieve it is supplied to the outlet channel.
    The closest to the invention to the technical essence and the achieved result is a device containing a vaulted sieve with a channel for supplying the initial mixture and an outlet channel, a nozzle for supplying air to the vaulted sieve lj.
    However, in the known device, the mixture of water with the granulate is supplied through the supply channel to the vaulted sieve almost tangentially, and, adjacent to the end of the supply channel, it is followed by a zone of air supply that overlaps a significant area of the vaulted sieve, which is formed by the circumferential surface of the valve Torah. Due to the rotation of the fan in the direction of flow of the water mixture with the granulate through the vaulted sieve, the air flow along this zone has both a transfer component and a radial component throughout the zone, due to which the granulate tends to follow the curvature of the vaulted sieve. The centrifugal force arising in this case then produces centrifugation of the water and passing it through the vaulted screen.
    The purpose of the invention is to increase the efficiency of dewatering the mixture by ensuring that water is thrown from the reciprocating moving granule.
    The goal is achieved by the fact that a device containing a vaulted Rito with a feed channel for supplying the original sorter and an exhaust channel, an air nozzle to the vaulted sieve, is provided with a lid adjacent to the wall of the air nozzle and to the wall of the exhaust channel, and the air nozzle is installed under the angle between the axis of the nozzle and the tangent to the vaulted case is 25 - 75.
    At the same time, the device is equipped with additional air nozzles and vaulted sieves arranged in series behind the main sieve and interconnected by means of a sloping transport channel, and the vaulted sieves are arranged in a zigzag manner.
    Moreover, the transport channel at the lower end is provided with a nozzle for supplying air in the direction of flow of the treated mixture.
    In addition, the device is equipped with a soundproofing casing with a pipe for air release, located in its upper part. FIG. 1 shows a general view of the device, FIG. 2 shows a device with three vaulted screens directed obliquely upward by the transport channel j in FIG. 3 shows a device with three arched sieves directly connected one after the other and a common, forming separate covers, by overlapping in FIG. 4 shows a device with three vaulted sieves in a zigzag-shaped arrangement placed in a closed case. The device comprises a vaulted screen 1, consisting of parallel transverse rods 2, between which there are gaps 3. Separate transverse rods 2 are held on the end sides by means of side walls. The vaulted sieve is equipped with a channel 4 for supplying a mixture of water with a granulate, the output nozzle 5 of which is bounded laterally by the wall 6 of the slotted nozzle 7. The slot nozzle 7 through the hose 8 is supplied with air that exits through the mouthpiece 9 of the output nozzle 10 at an angle of 30 where oi is the angle between the middle point of entry of the air flow 12 and the tangent 13 to the vaulted sieve 1. The device is equipped with a lid 14 and an exhaust channel 15. The water with the granulate mixture emerging from the nozzle 5 is accelerated by an air flow 12, hits the bottom of the vaulted sieve 1 , and due to the angle about (, 30 ° a substantial part of the water is withdrawn, and the granulate bounces off the rods 2 and is thrown onto the lid 14. From it, it is reflected back to the vaulted sieve 1 and moves in a zigzag manner until the granulate reaches the end of the vaulted sieve 1 and does not enter the outlet channel 15, in which it is transported to the next stage of processing due to kinetic energy. During this reflective movement, the granulate water is pushed into the gaps 3 between the rods 2. Thus, the granulate enters the flow channel 15 almost St. rimmed from water. The cover 14, which is involved in the creation of the reflective movement, passes from the back wall 6 of the slotted nozzle 7 to the outlet channel 15 and thus ensures that neither 836 one of the granules reflected from the sieve 1 of the granule can B1 1 jump outwards. Three vaulted sieves 1, 16, and 17 with slotted nozzles 7, 18, and 19, respectively, are connected to the device (Fig. 2), with channel 15 being connected between vaulted sieves 1 and 16. Air is supplied to this device through inlet 20 for air, supplying air to the distribution tank 21, from which the air supply hoses 8, 22 and 23 branch off to the slotted nozzles 7,1.8 and 19. The slotted nozzle 18 is positioned so that its front wall 24 passes into the channel 15- , so that the water penetrating into the channel 15 must flow through the front wall 24 and thereby, it enters the air flow exiting the slit nozzle 18. This water can be discharged using a vaulted sieve 16. Separating it with vaulted sieves 1, 16 and 17, water is discharged through outlets 25-27 for water. Air is supplied to channel 15 at the end of vaulted sieve 1 by means of an inlet nozzle 28 for air directed obliquely upwards, and the granulate supplied to channel 15 is transported in channel 15 upwards to the vaulted sieve 16. The device (Fig. 3) is directly connected one after another, three vaulted sieves 29-31. The mixture of water with the granulate enters the supply channel 32 and enters the discharge channel 33, located approximately 1 m above the supply channel 32. Each sieve 29-31 is provided with slotted nozzles respectively 34 - 36 and pipes 37 - 39 filing in airs Above the slit nozzles 34-36, an overlap 40 is provided, forming a lid for each vaulted screen. In the device (Fig. 4), following the vaulted sieve 1 provided with a slotted nozzle 7, there are two vaulted sieves 41 and 42 connected by transport channels 43 and 44. At the lower end of the transport channels 43 and 44, there are inlet nozzles 45 transversely through the corresponding transport channel and 46 for air, which create an obliquely directed upward flow in the transport channel, which transports the pellets through the transport channel upwards. Under each of the channels 43 and 44, air distribution boxes 47 and 48 are provided, to which air flows through the inlets 49 and 50 for Air. Air flows are perpendicular to the cross section of the transport channels 43 and 44 so that under the action of air distribution boxes 47 and 48, the air flow inside the air distributing boxes, which is directed mainly symmetrically with respect to the air inlet nozzles 45 and 46 for the air. From the inlet nozzles 45 and 46 for air along their length, to a large extent at the same speed, so that the granulate is uniformly accelerated over the entire width of the transport channels 43 and 44. The air distribution boxes 47 and 48 ensure that the flow air in this region occurs with only one deviation, namely directly in front of the inlet nozzles 45 and 46 for air, whereby the flow losses remain correspondingly insignificant. Following the vaulted screen 42, the following transporting channel 51 obliquely upwards is turned on, which at its lower end is provided with an air inlet nozzle 52 transversely through it, which receives its air flow through the air distribution box 53. Distilled through the device 51 is discharged through channel 51 granules. The vaulted screens 1, 41 and 42, together with the transport channels 43, 44 and 51, are placed in a soundproof casing 54, the bottom 55 of which serves as a collection for the water to be separated by the device. An outlet 56 for water is provided in bottom 55, and an outlet 57 for air in case 54. The inlet for the granulate 58, similar to the entrance of the vaulted sieve 1, is introduced into the casing 54. Thus, due to the fact that the slotted nozzle passing through it across the vaulted sieve for supplying air flow in such a way that the water with the granule is carried along by the air flow on the vaulted sieve at an angle, lying approximately between 25 and 75, and in the direction of flow behind the slotted nozzle is an overlapping vaulted sieve of krgak adjacent to the back wall of the slotted nozzle and reaching the outlet channel to Str the reflective motion achieved high efficiency of dewatering the mixture. The mixture of water with the granulate due to the air flow that is sharply focused by means of a slit nozzle is substantially accelerated and thrown onto the vaulted screen in the direction of the air flow, which differs significantly from the direction of the tangential, and water in its predominant part immediately flows through the vaulted sieve. Due to the angle of contact of the granulate, it is rejected from the vaulted sieve, so that, in interaction with the lid that overlaps the vaulted sieve behind the slotted nozzle, a reflective movement occurs, during which the water still attached to the granule is largely discharged from the granule. The granulate then leaves the end of the vaulted sieve largely free of water.
