Description

(54) FISHING DRUM

one

The invention relates to the field of surface treatment of parts and can be used in machine building and other industries.

Tumbling drums are known that contain a shell enclosed from blocks, the working surface of which is provided with a coating made in the form of rods of cable segments Shch.

The disadvantage of the known devices is the inconvenience of replacing the coating with its rapid wear,

The purpose of the present invention is to increase the wear resistance of the coating of the working surface of the drum.

This goal is achieved by the fact that the blocks are made of a material with a high wear coefficient in relation to the coating material;

FIG. 1 shows a general view of the described drum; FIG. 2 is a section along A-A in FIG. I; in fig. 3 end strips protecting the shells

(blocks) from the pro-positive displacement; Fig, 4 - kr "1lenkv shell between plastivam.

The tumbling cleaning drum contains drum 1, bandages 2, supporting rollers 3, electric motor 4 with a 5t gearbox, with shaft 6 connected to rollers 3, exhaust device 7 with a fan 8 and an electric 10 engine 9, lot (1O, inclined re - a grill 11, a plate conveyor 12. The drum is mounted on the frame 13, resting on one side (front) on the axis 14, the other (rear) on the screw 15 s

15 with a nut arranged in a glass 16. The axis 14 and the glass 16 are fastened and the turn on the concrete foundation 17. Longitudinal radially located plates 18 are welded inside the drum,

20 between which are placed aluminum blocks 19, (shells), reinforced with a cable and closed from mixing with slats 20 with kerchiefs 21.

The shape of the aluminum shells represents a truncated pyramid, the dimensions of which are determined by the dimensions between the longitudinal rational plates, and the height of the shells is equal to the height of the plates. The shell is reinforced with a cable, the ends of which in the form of a brush protrude by the size of 20 diameters of the wires, from which the cable is reinforced. When reinforcing, the ends of the cable are bent and poured in the form of a Latin letter. To prevent the drum from moving during the operation of the band 2, the stop rollers 22 are installed. A conveyor belt 23 is installed for transporting the ground over the ground.

Tumbling cleaning drum works as follows.

The plate conveyor 12 castings are fed to the tray 10, and from there into the drum 1. The drum is rotated by the electric motor 4 through the gearbox 5, the shaft 6 and the drive rollers 3 coupled to the bandages 2. As the drum rotates, the castings are freed from the ground by rods , burrs and burrs. At the same time, the tilting of the drum gives the rotating parts and the ground a forward movement, as a result of which the castings together with the earth and waste from the waste and burrs fall onto an inclined sieve: 11. Part of the ground and small waste through the opening hectare in the grille spills onto the conveyor belt 23. Suitable castings are removed from the conveyor and are visited on the suspended cradle conveyor (not shown). Marriage and coarse flare, the pad on the head of the magnetic drum of the next conveyor {not shown), is captured and carried away to the container box, and the earth from the conveyor 23 falls on the grate, and through it into the basement in the bunker (not shown in the figures) .

The rotating parts in the drum, striking the torpedo shells of the shells 19 with a cable, do not create noise, since the brush from the cable is a good sound absorbing material. To replace worn shells, it is enough to unscrew the strips 20 and release the closing gussets

0 21. Instead of the worn ones, others are inserted and fixed again. During the operation of the drum, bpac may be weakened in the grooves due to the whole thing. Dust penetrates into the gaps.

5 earth and pick up the shell from the bottom as long as it does not seal between the plates 18, closing the gaps that have formed. A layer of earth 24 all the time props up the shell 19 wedges it between the NIU plates 18 (see Fig. 4). The adjustment of the tilt of the drum in order to increase productivity is made by rotating the screw 15 by the required amount in the nut arranged in the glass 16.

Claims (2)

1. A galtovochny drum containing a shell made of blocks, the working surface of which is provided with a dug made in the form of cable sections, characterized in that, in order to increase the wear resistance of the working surface of the drum 5, the material is made of a material with a large factor wear in relation to the coating material. 2. A drum according to claim 1, which is also distinguished by the fact that the blocks are completed 0 from aluminum. Sources of information taken into account in the examination 1.
