(54) DEVICE FOR SORTING EXTENDED

one

The invention relates to devices for sorting bulk materials and can be used in the manufacture of building materials, in the woodworking industry and in other sectors of the national economy.

A device for sorting elongated particles is known, comprising two shafts (one register) with rollers on which the ropes are pulled, and the diameter of the driving rollers decreases from the middle to the edge 1.

The disadvantages of the known device are its complexity and low sorting efficiency.

The closest to the invention by. The technical essence and the achieved result is a device for sorting elongated particles, including a loading device, two rotatably mounted shaft with rigidly mounted disks on which strings are pulled, and discharge chutes of sorting products 2.

PARTICLES

The disadvantage is the poor quality of sorting.

The purpose of the invention is to improve the quality of sorting.

This goal is achieved by the fact that a device for sorting elongated particles, including a loading device, two rotatably mounted shaft with rigidly mounted disks on which strings are pulled, and discharge sorting chutes, are equipped with additional disks mounted freely on each shaft and located between rigidly fixed disks, with the additional disks of one shaft connected by means of strings with the main disks of the other shaft, and the shafts installed with awn rotating at different speeds.

FIG. 1 and. 2 shows the proposed device; in fig. 3 shows section A-A in FIG. one.

A device for sorting the elongated particles includes a discharge device 1, a frame 2, a drum feeder 3 with a driving pulley 4, the drive shafts 5 and 6 with pulleys. 7 and 8. On each shaft

alternating rigidly mounted 9 and freely mounted disks 10 are installed, covered by endless flexible strings 11.

The device is closed by a dust cover 12 with a chimney 13. Vertical walls 14 are installed between each upper and lower string branch. In the lower part of the device, an outlet 15 is installed to collect elongated particles and 16 to collect an oversize product.

The device works as follows.

The source material from feed chute 1 is fed to the drum feeder 3, and then to the screening surface formed by the strings 11. The drive shafts 5 and 6 rotate at different speeds in one direction, as a result of which the speed of movement of the strings 11 is different. Particles of material falling on the screening surface move with it. At the same time, the particles, due to the different speeds of the neighboring strings, turn, the elongated particles, taking a position along the jets, fall into the gap between the strings and enter the G5 estrus. Particles larger than the distance between the strings moving with the screening surface enter the chute 16. Vertical walls 14 serve to prevent particles from falling between the strings 11 and the discs 9 and 10.

In order to comply with the safety precautions for the operation of the device, it is closed by the casing 12, and the dust generated in the impurity sorting is removed through the chimney 13.

The application of the proposed device allows improving the quality of sorting materials containing a significant amount of elongated particles.
