Description

The known rotating barrels for washing and sifting ores and other materials cannot be used to leach ores and wash them after acid treatment due to rapid wear and dissolution of their metal parts.

The proposed barrel has a wooden lining inside of tightly fitting longitudinal bars, as well as a wooden face lining. Before laying the bars, between the shell of the barrel and the lining, a layer of thin sheet rubber is laid with preliminary preking in the hot state of the entire inner surface of the barrel's shell, and the assembly of the wooden lining is also performed with hot impaction, which ensures the waterproofing of the metal of the barrel of the barrel from acid pulp and prevents it from corrosion and dissolution.

In addition, the guide vanes are made of wooden bars located inside the barrel but with a helix, by which the ore not only moves intensively during the rotation of the barrel, but also moves continuously from the loading end to its unloading end to unload the processed ore from the barrel.

The drawing shows the construction of the barrel.

The base of the barrel is the iron shell /, the wooden lining 2 is attached to the Heil from the inside by bolts. Sheet rubber 3 is laid between the shell and the wooden lining. The ends of the barrel, also lined with wood 4, have round holes 1, while at the loading end 5 a hole of a larger diameter than that of the discharge end 6. Inside the barrel, along a helical line, are wooden blades 7 of bars, bolted to the lining and shell.

The ore is loaded into the barrel by the chute 8 in the loading window 9. And the leached and washed ore is unloaded through the unloading

a window W to a discharge chute 11. Fresh water is supplied to the inside of the barrel through a pipe 12 passing through the discharge window, and the waste 1UDS is discharged through the loading window and the chute 13.

The barrel with outer tires 14 rests on the rollers 15. To prevent the rollers from sliding along the tires, the rollers of one side are connected by a flexible drive 16. The rollers are supported by bearings on the 1-frame 17. The rollers are received from the electric motor through a wedge-shaped transmission from the pulley 18.

Prevention Invention

. A barrel for acid removal; an ore treatment, characterized in that a layer of thin rubber is laid between the metal shell and the wood lining with preliminary grounding of the inner surface of the shell to protect it from corrosion.

2. A barrel according to claim 1, characterized in that the intensive movement is carried out by rotating it on rollers and moving the ore from the loading opening to the discharge opening by means of wooden blade blades continuously arranged along a helix, on their screw surface.
