u 1. 1 The invention relates to vertical vibration machines and can be used in chemical, food, construction and other sectors of the national economy, in particular for sieving and transporting bulk materials of various sizes in a vertical plane. According to the main auth. No. 1087203 is known for a vertical vibrating screen containing a screw conveyor chute in the form of a clasp of elastic elements installed radially with a gap relative to each other and a pallet located under it in the form of an inclined screw surface rigidly connected to the supporting column along the internal helix, and with the transport chute along the external helix, vibro drive, elastic connections, loading and unloading connections. The disadvantage of the screen is the inability to select more than two products. The purpose of the invention is the paciaHpieHHe classification school. The goal is achieved by the fact that the known screen is equipped with partitions installed inside the carrier column along its height with the formation of channels, as well as partitions rigidly connected with the pallet and the carrier column with the formation of sections the number of which is equal to the number of channels, the latter being conjugated with the sections through the windows in the carrier column, located in the apexes and the lower parts of the sections, and the distance between the clamp-shaped elements of the different 1 and 1 sections are increased by the height of the column. Fig. I schematically shows a vertical vibrating screen, a longitudinal section; figure 2 is a view of And figure 1; FIG. 3 is a section BB in fig. 1. The vertical vibrating screen consists of a carrier column 1 with discharge openings 2, loading) and 4 discharge pipes of elastic clamp-shaped elements 5 forming the screening surface of the groove 6. Under the groove 6 is placed a pallet 7, made in the form of an inclined screw surface, on which a protective irrigation system 8. 9 is installed. The screen is mounted on an elastic suspension 9, driven by a vibrating actuator 10. Partitions 11 are rigidly connected to the pallet 7 and column 1, which form sections located whiskers on column height 1. The pattern of elements inside each section is set at the same distance in different sections; the distance between these elements is made increasing along the height of the column. Partitions 12 are installed inside the column to form channels 13, the number of which is equal to the number of sections. Ka, which connects the channel with the section through windows in the carrier column, installed in the lower and upper parts of the sections. The installation works as follows. The initial product enters through the discharge port 3 to the screw conveying chute 6. When the vertical drive 10 is turned on, the installation makes helical oscillations. Under the action of centrifugal flow, the product gradually rises along chute 6. At the same time, a part of the product, consisting of the smallest fractions and dust, is washed out with liquid coming from the irrigation system 8 and through the minimally established gap between the clamp-shaped elastic elements of the first section falls on the inclined helical pallet 7 and due to the inclination of the latter through the discharge openings 2 is led into one of the discharge channels 13. A larger fraction of the next class of products is screened out in the next section. Since the bulk material trapped on the screw inclined pallet 7 moves not only down (most) under the force of gravity, but also up (smaller part) under the action of vibration, windows 2, located at the beginning and at the end of the section, allow you to fully output classified product into its channel 13, preventing its accumulation in sections. The large unexplored fractions reach the top of the column 1 and are discharged through the discharge pipe 4.

Such an implementation of the screenedness of the installation and the increase of it will enable you to get a quality product reliability through operational fractions, increase production. removal of sifted fractions.
