IMPORTANT Daskovy ROTOR

Technical field

The utility model relates to the field of technology for the separation of bulk materials in the separation of foreign objects and straw parts, in particular, to devices with a sifting surface of a rotary type, used in peat, coal industries and agriculture.

State of the art

Known roll-disk rotor, consisting of a shaft on which rigidly and parallel to each other. Disks are installed, and bearings / I / are mounted on the ends of the shaft.

The disadvantages of this roll-disk rotor is the high complexity when replacing broken discs, as well as when changing the distances between adjacent discs and shafts of adjacent rotors.

Closest to the claimed device relates to a shaft-rotor containing a shaft with bearing bearings at the ends, on the common key of which are mounted parallel to the disks and spacer sleeves, alternating between each other. Moreover, the remote bushings determine the size of the hole between adjacent disks / 2 /.

The disadvantages of the prototype include the difficulty in replacing damaged disks and when changing the distance between adjacent disks and adjacent rotor shafts, because of the need to disassemble the drive and rotor. In addition, high metal consumption is required for disks, as to increase their rigidity, the thickness of the discs is 10-20 mm.

Utility Model Disclosure

The objective of the utility model is the creation of a roller-disk rotor, in which labor and labor costs would be reduced during repair and commissioning. In addition, one of the tasks is also to reduce the metal consumption of the device.

This object is achieved by the fact that in the roller-disk rotor, including a shaft with bearing bearings at the ends, on which the disks and spacing sleeves are alternating, the disks and spacing sleeves are detachable, and removable working elements are installed around the perimeter of the disks, having an U-shaped profile from the end.

Brief Description of the Drawings

The proposed roller-disk rotor is illustrated by drawings, where :)

in FIG. I - roll-disk rotor, side view; in FIG. 2 - a disk assembled in working condition; in FIG. 3 - working element of the disk; in FIG. 4 - working element of the disk, end view.

The best option for implementing the device

The roller-disk rotor includes a shaft 1 mounted on bearings, on which disks 2 are rigidly mounted, made detachable from two half-disks and connected to each other and shaft I by means of nuts 3 located on both sides of the half-disks. On the shaft I are also rigidly mounted bushings 4, made detachable from two halves and pulled together by clamps 5, the disks 2 and the distance bushings 4 alternate with each other. Working elements b are rigidly attached around the perimeter of the disk 2 with the help of fingers 7. Along the perimeter, the working elements 6 have a U-shaped profile.

Roller disk rotor operates as follows.

Several rotors shown in FIG. I, install bearing bearings of the shaft I on the bed in a row (not shown in the drawings), and a screening surface is formed.

After that, depending on the zedp, the Anna size of the marketable product and the permissible contamination of its foreign objects, establish the required size of the openings between; adjacent discs 2 of each rotor and adjacent shafts I.

To adjust the distances between the disks 2, they remove the clamp 5 and the distance bushings. And release the nuts 3 and, starting from the extreme disk 2, move them one by one on the shaft I to the required distance. After that, the disks 2 are fixed on both sides by nuts 3 and the detachable spacer sleeves 4 of the required size are installed between them. Then, the split distance bushings 4 are pulled together by clamps 5.

The rotors thus prepared supply the material to be processed, for example peat. In this case, a part of the material, the size of which is smaller than the holes formed by the adjacent disks 2 of the rotor and adjacent shafts I, falls through these holes, and the distance sleeves 4 prevent winding of fibrous inclusions on the rotating shaft I and prevent damage to the thread of the shaft I by failing solid foreign inclusions (iron objects, stumps). The non-sifted part of the material by the rotating discs 2 moves in the direction of their rotation. In this case, the material

If the working element b is damaged, for example, if it breaks, finger 7 is removed, the damaged working element b is removed and a new working element b is installed instead, which is fixed with finger 7 on the disk 2. The length of the working element is equal to the length of the large face of the disk 2 provides a closed contour of the perimeter of the disks b, this excludes the accumulation of material, in particular fibrous inclusions, at the joints.

The implementation of the working element b U-shaped profile simplifies its production and replacement, in case of breakage, because it simply fits onto disk 2 and secures with finger 7.

This device can significantly reduce the complexity of work when replacing disks and changing the size of the holes between adjacent rotor disks depending on the specified size of the sifted material and the permissible size of foreign objects in it by carrying out these operations without disassembling the rotor, through the use of detachable disks and mounting them on the shaft nuts.

In addition, the active shaft length is increased due to the mounting of discs by means of two nuts located on both sides

. discs T Change the distance between adjacent shafts during installation

rotors in a row by changing the size of the spacer bushings without disassembling the rotor. The long-term service life of the discs increases due to the introduction of removable working elements, which means that the working capacity of the rotor increases. The metal consumption for the manufacture of disks is reduced by reducing their todcins, for example, from 10 mm to 4 mm, by introducing working elements that directly perceive impact in a collision with solid objects. The manufacture of the working element is simplified by performing the groove of the U-shaped profile. -I Useful rattors.
