Description

The invention relates to the field of non-ferrous metallurgy, specifically to equipment used for the technological processing of electrolyzers for the production of aluminum, namely the cleaning of the flange sheet from the frozen electrolyte.

When servicing electrolyzers, bursts of solidified electrolyte and spillage of alumina from the flange sheet of the electrolyzer were manually removed using scrapers and brooms. The removal process is inefficient and environmentally harmful, because dusting occurs.

Closest to the technical nature of the claimed device is a flange plate cleaning company Henkon (http://www.hencon.ru/products/potrooms/soderberg/pet.html). Flange plate cleaning equipment is installed on the boom of a special self-propelled machine. A special brush due to the hydraulic drive ensures cleaning of the flange sheet on the sides of the cell. The flange sheet cleaning operation consists of sweeping alumina from the flange back to the crust.

The disadvantages of the prototype are excessive dust formation when sweeping alumina onto the electrolyte crust and low cleaning efficiency of the solidified electrolyte on the surface of the flange sheet, which is weakly, ineffectively amenable to destruction by brush.

The objective of the invention is to improve the cleaning efficiency, due to the continuous and continuous destruction and removal of the frozen electrolyte from the surface of the flange sheet and environmental improvement, by reducing dust formation.

The technical result consists in the development of a device that ensures the achievement of the task.

This object is achieved by the fact that in the device for cleaning the flange sheet of an aluminum electrolyzer, including a hydraulic drive mounted on a self-propelled machine and a cleaning tool mounted on the frame and equipped with a protective guard, according to the claimed solution, the working tool is made in the form of a milling cutter consisting of disk elements of at least two, and a conical element of different diameters with teeth along the perimeter, mounted coaxially on the shaft on both sides relative to the central disk element, diam the meter of which is made smaller than the diameter of the extreme disk element and larger than the diameter of the conical element mounted on the output end of the shaft.

The invention is complemented by private distinguishing features that contribute to the achievement of the claimed technical result.

The disk elements and the conical element of the milling cutter are made of metal.

The frame of the device is made with the possibility of fixing on a pitchfork serial forklift.

The design of the cleaning device is illustrated in the drawings, where in FIG. 1 shows a general view of the device mounted on the forks of a serial forklift truck, the dotted line shows the raised position of the device; in FIG. 2 is a general view of the device, in FIG. 3 is a transverse section through a milling cutter.

In the figures, structural elements are marked with the following positions:

Forklift 1;

Stacking mill 2;

Safety fence 3;

Disc element of a type-milling cutter of smaller diameter 4;

Disc element of a type-milling cutter of a larger diameter 5;

Conical element of a milling cutter 6;

Shaft of type-setter 7;

Keyway 8;

Frame 9;

Forklift 10 of a forklift truck;

Frame Rack 11;

The intermediate sleeve 12;

The intermediate gear 13;

Clutch housing 14;

The hydraulic motor drive 15 of the shaft 7;

Rectangular sockets 16;

Special Screws 17.

The cleaning device includes a working body mounted on the frame of a self-propelled machine - forklift truck 1, made in the form of a type cutter 2 for cleaning the flange sheet with a protective fence 3. The type setter 2 is made of a disk element 4, a disk element 5 and a conical element 6 with teeth along the perimeter . The disk element 4 is mounted coaxially on the shaft 7 between the disk element 5 and the conical element 6. The conical element 6 is mounted on the output end of the shaft 7. The diameter of the disk element 4 is made smaller than the diameter of the disk element 5 and larger than the diameter of the conical element 6. Disk elements 4, 5 and the conical element 6 is made of metal, for example, structural steel for general purposes. Compound cutter 2 is fixed with a keyway 8 on the shaft 7.

Stacker mill 2 is mounted on a frame 9, made with the possibility of fixing on a pitchfork 10 serial forklift. A rack 11 is mounted on the frame 9, to which the intermediate sleeve 12 is fixed. To the intermediate sleeve 12, on one side the intermediate gearbox 13 is fixed, and on the other hand, the clutch case 14 is attached to which the drive motor 15 of the shaft 7 is fixed. On the output shaft of the intermediate gearbox 13 the shaft 7 is fixed by means of a flange connection. The set-up cutter 2 and the rotating flange of the output shaft of the gearbox 13 are closed by a protective guard made in the form of shields 3. To fix the frame 9 with the fixed set-up cutter 2 onto the forks 10 of the loader, AME 9 are four rectangular slot 16 into which and installing fork loader 10. The frame 9 is fixed with special screws 17.

The cleaning device is installed on the forks of a serial forklift of any brand, with a lifting capacity of 3-3.5 tons, which has an additional section of the hydraulic distributor in the configuration. The flange sheet is cleaned by rotating the hydraulic motor drive with the hydraulic system of the loader. Raising and lowering the cleaning device is provided by the mechanism for raising and lowering the forks of the loader, and moving the device along the electrolyzer - by moving the loader.

The device is intended for cleaning the flange sheet of S-8B (E), S-8BM (E) electrolyzers with a special multi-toothed milling cutter, due to the rotational movement of which, bursts of solidified electrolyte crack on the surface of the flange sheet and are removed to the electrolyte crust.
