Description

(54) ALUMINUM SERVICE MACHINE

I

The invention relates to devices that are installed in the field of electrolytic production of aluminum for the mechanization of technological operations.

A known machine for servicing aluminum electrolysis cells, comprising a self-propelled frame equipped with devices for breaking the electrolyte crust and loading alumina from the hopper into the electrolyzer 1.

The disadvantage of this machine is the need to locate rail tracks on the electrolysis shop floor, separate isolated areas of which must have the potential of an appropriate cathode device, the presence of two sets of devices and mechanisms or drives, a high intensity of metal and a significant load on the building structures of the electrolysis shop.

Also known is a machine that contains a G-sdraznuyu, equipped with a hopper for alumina, devices for loading alumina and the height of the peel of electro-electrolysers.

The frame with the lower opera which is installed on the driving carriage and the upper support with the rollers is movably mounted on the CSJ monorail.

The disadvantages of this machine are the presence of two sets of devices and mechanisms for servicing electrolyzers, increased metal consumption, as well as a significant load on the support columns of the workshop building.

ten

The purpose of the invention is to increase the specific productivity of the machine, reducing the number of devices and mechanisms for servicing electrolyzers, reducing the loads on the supporting structures of the building.

The goal is achieved by dividing the L-shaped frame into two separate parts connected in an upper horizontal section by a hinge

P with a vertical axis, this part of the frame with the lower support on the chassis, 1 shower truck has the ability to rotate the specified axis and fixation and serve with an opera to install one device to destroy the electrolyte crust and one device to load alumina in the electrowirer. FIG. 1 shows the proposed machine, a general view; in fig. 2 - the same, side view. The machine contains a frame 1 supported by non-driving wheels 2 on the overfoot rail 3 and supported from tipping over by supporting wheels 4 in the guide rail 5. Electrolyte crust destruction device 6, alumina hopper 7 with device 8 for loading alumina into the electrolyzer 9 bath are installed on -shaped metalwork 10. The axle 11 connects the T-shaped metal structure 1O to the frame 1. The H-metal structure 1O rests on the undercarriage 12 with the drive 13. The machine is fixed in the working positions by the stoppers 14 and 15. When moving uu along rows electro / Ghizer machine produces destruction electrolyte crust and loading of alumina in the bath on one side of the cell. The trolley 12 with 1d5 water 13 transmits the pulling force through the L-shaped metal structure 10 and the stopper l4 to the frame 1. At the same time, the stopper 14 holds the L-shaped metal structure 10 together with the frame 1, and the stopf 15 is not engaged. The direction of the machine sets the guide rail 3. If it is necessary to treat the bath from the opposite side of the electrolyzer 9, in the zone of the R-section of the L-shaped metal structure 10, the stopwatch 14 frees the rotary part of the machine from frame 1, and CTonqp 15 works with and prevents moving the machine along the back of the electrolyzers. The carriage 12 with the drive unit 13, moving together with the L-shaped metal structure 1O radially around the vertical axis 11, moves to the opposite side of the electrolyzer 9, after which the stopper 14 operates and holds the turning part of the machine (L-shaped metal structure 10) together with the frame 1. The stopper 15, which prevents movement of the machine along a row of electrolytic cells, is turned off. The machine is ready for operation on the side of the cell. The use of the proposed machine makes it possible to increase the specific productivity, reduce the number of devices and mechanisms for servicing the electrolysis cells, reduce the cost of sinking rail tracks, and increase labor productivity. The invention The machine for servicing aluminum electrolysis cells, containing an L-shaped, equipped with a hopper for alumina and devices for loading alumina and destruction. electrolyte peel frame, the lower support of which is mounted on the driving drive carriage, and the upper support with rollers is movably mounted on the monorail, I differ from heme, in order to increase the specific productivity of machines, reduce the number of devices and mechanisms and reduce the load on the supporting structures of the building The L-frame is made of two separate parts connected on the upper horizontal section by a shirnir connection with a vertical axis, while the frame part with the lower side on the driving drive carriage has POSSIBILITY rotation about said axis, and fixing and serves as a support for mounting a device to break the electrolyte crust and a device for loading of alumina in the electrolytic cell.
