SU135834A1 - Continuous device for separating heavy impurities (stones, sand, etc.) from roots and tubers on a hydrotransporter - Google Patents

Description

A device for continuous separation of heavy impurities (stones, sand, etc.) from root and tuber crops on a hydrotransporter, made in the form of a mesh horizontal rotating cylinder mounted on the polished part of the groove of the hydrotransporter and equipped with a drainage tray for impurities is known.

The proposed device, in comparison with the known, provides for the capture and removal through the bypass tray at the same time of large heavy impurities from the inner surface of the cylinder and small fine impurities from the cavity under the mesh cylinder.

The design feature of the device is that on one of the end parts of the cylinder, around the circumference of its surface, two hollow pockets, open at one end, are fixed, the cross section of which increases in the direction of rotation of the cylinder; the front edges of the pockets are scrapers for scooping up fine impurities; Pocket cavities communicate with the cylinder cavity through openings on the side opposite to the inlets of the pockets. To move impurities to the pockets on the inner and outer surfaces of the cylinder, fins are arranged along a spiral line.

The drawing shows a device of continuous action for separating heavy impurities from root and tuber crops on a hydrotransporter.

The hydraulic conveyor 1, through which, for example, beets are supplied, is contaminated with large and small heavy impurities (stones, sand, etc.), has an extended

No. 135834 2, an open-top chute 2. In this section of the hydrotransporter, a continuous-action device for separating impurities from the beet is mounted, mounted on the shaft 3, an horizontal horizontal mesh 4, open from the ends, rotating from the drive 5. From the entrance to the cylinder 4, chute 2 Provided with a collection 6 for sand separated from beets. On the exit side of the cylinder, chute 2 has part 7 (in a cone-shaped sheet), the dimensions of which at the exit end correspond to the dimensions of the chute of the conveyor itself. On the front inlet part of the cylinder 4 On its side; 5-ring pockets 8 and 9, formed by cylindrical shells W, 11 and 12, 13, respectively, are reinforced. Pockets 5 and 5 are made with an increasing cross section in the direction of rotation of cylinder 4 along arrow C. The leading edges 14 and 15 of the pockets are scrapers that scoop fine impurities (inecoK, etc.). For large heavy impurities, a collector 16 is provided in the gutter. On the side opposite the inlet openings 17 and 18 of the pockets, in the inner shells 10 and 12 there are openings 19 and 20 through which the cavity of the pockets communicate with the cavity of the cylinder 4.

The ribs 21 are reinforced on the inner surface of the cylinder 4, and the ribs 22, located along the spiral line, are fixed on its outer surface. In the drawing, reference numeral 23 shows the level of a mixture of beets with water transported by a transpoter.

When the mixture enters the cylinder 4, sand and small stones pass through the openings of cylinder 4 and are deposited in chute 2. The ribs 22 move (as the cylinder rotates) sand and small stones countercurrently to the movement of the beet-water mixture to the collector 6, and the ribs 21 move to the collection 16 large stones, which with the HOTO-KOJM mixture in the central channel, were pushed inside the cylinder. Immersed in a mixture of beet and water, located on the extended section of the chute of the hydrotransporter, the pocket (first one and then the other) is filled with water and takes the sand sinking at the bottom of the collector 6 through the hole 17 and then the stones from the collector 16. With the appropriate position a pocket in which there are sand and stones, the latter are thrown out through the hole in the inner shell on the bypass tray 24. During the rotation of the cylinder, the beet roots, settling inside the cylinder in places with a low flow rate, move to its center A bed where the speed is sufficient to move the beet roots to the exit from the cylinder.

The described device does not require deep sampling under a hydrotransporter and can also be used to separate impurities from other root and tuber crops (potatoes, vegetables, groundwater, etc.).

Claims (2)

1. A continuous operation device for separating heavy impurities (stones, sand, etc.) from root and tuber crops on a hydrotransporter, made in the form of a mesh horizontal rotating cylinder mounted on the broadened part of the hydrotransporter chute and equipped with a drainage tray for impurities, that, in order to trap and remove to the tray at the same time large heavy impurities from the inner surface of the Cylildr and small heavy impurities from the cavity under the mesh cylinder, on one of the end parts there is a cylinder and along its circumference, two hollow open pockets on one end (the front edges of which are scrapers for scooping up fine impurities: sand, etc.) are reinforced with an increasing section in the direction of rotation of the cylinder, the cavities of which communicate with the cavity of the cylinder through the holes at the other end of the pockets. 2. The device according to claim 1, wherein the ribs are arranged on the inner and outer surfaces of the cylinder to move the impurities to the pockets. f; /
