To achieve this technical result, the apparatus for separating beet debris from light impurities contains a feeder and two oblique drums installed with the formation of a pitched surface and rotatably disengaged, provided along the entire length with longitudinal rows of catching pins and holes that are designed to recess the pins, rigidly mounted on an adjacent drum, and their length exceeds the distance between the drums. Above the sorting zone, a reflector of beet debris is installed, made in the form of two combs, the rods of which are fixed on an elastic tape with the possibility of oscillation in the immediate vicinity of the catching pins.

The proposed installation is illustrated by the drawings presented in figures 1 and 2:

FIG. I shows a side view;

FIG. 2 is a transverse section through the installation along A - A of FIG. 1.

The apparatus for separating beet debris from light impurities contains two inclined drums I. Their synchronous rotation is broken by a drive 2. The gap between the drums in combination with a pitched surface forms a sorting zone where a mixture of beet debris and impurities is fed through feeder 3. Tray 4 discharges large beet debris suitable for processing. Under the drums there is a collection 5 for light impurities and small fragments. Over the sorting zone along the drums, a reflector of debris 6 is installed.

The working bodies of the drums I are catching pins 7, rigidly fixed to the surface of the drums in longitudinal rows. The length of the pins 7 exceeds the gap between the drums. For their recession, oval holes 8 are used, made on the surface of the mating drum according to the location of the pins.

of the adjacent rods 9, fixed at one end on an elastic tape 10 with the possibility of oscillation of the individual rods. The tape 10 is mounted on a longitudinal rod II, under which there is a limiter 12 supporting the rods 9 in the sorting zone at a certain angle in the immediate vicinity of the catch pins 7.

Installation for separating beet debris from light impurities works as follows.

Synchronized rotation of the drum I is carried out by the drive 2. A mixture of beet debris and light impurities (tops, weed rhizomes, pulps, etc.) is fed to the sorting zone via feeder 3. Getting into the pharynx between the inclined drums that rotate in a flail, the mixture is subjected to intensive mixing by the catching pins 7, rigidly fixed to the surface of the drums. At the same time, light impurities are captured by pins and removed from the sorting zone, and also partially fall through the technological gap between the drums into the collection vessel 5. Being freed from light and small impurities, large beet debris moves due to a slope along the axis of the drums and enters tray 4 to remove clean debris for recycling. To ensure reliable operation of the installation, the length of the catching pins 7 exceeds the gap between the drums, the value of which is regulated by technological conditions. Once in the sorting zone, each assault is recessed into the corresponding oval hole 8 in the mating drum body.

To eliminate accidental emissions of large beet debris from the sorting zone, a debris b reflector is installed above it in the form of two combs, the rods of which hang in the immediate vicinity of the catching pins without touching the surface of the drums. Large beet debris that accidentally caught on pins 7 during drum rotation collide with the rods 9 of the reflector 6 back into the sorting zone, without hindering light impurities from being pulled out by pins 7. This is because light impurities (tops, pulp, weed rhizomes) at the moment of contact with the reflector rods are on the surface of the drums almost horizontally in an adherent state and can no longer slide back into the sorting zone. The elastic tape 10, on the 11th axle) the rods 9 are attached, acts as a spring, allowing from, -. individual rods deviate independently of each other by a certain angle until they push the chip caught on pin 7 back into the sorting zone and then return them to their original position. The limiter 12, located under the tape 10 along the rod II supports the rods 9 in working condition at a certain angle, excluding their sagging in the vertical position.

The use of this installation provides high-quality separation of a mixture of beet debris and impurities, which allows to reduce beet mass loss by 5 - 10%; increases the reliability of work while reducing metal consumption and simplifying the design; improves working conditions by reducing the noise level during operation of the installation.

This installation is applicable at processing plants, in particular, in the washing department of a sugar beet factory.
