SU720053A1 - Apparatus for packing sole joints of aluminium electrolyzer - Google Patents

Description

I

The invention relates to non-ferrous metallurgy, in particular, to devices for servicing electrolyzers for producing aluminum.

A known installation for stuffing the bottoms of the bottom of an aluminum electrolysis cell, comprising a frame of a self-propelled bogie with mounted power cylinders fitted with a percussion mechanism connected with a padding needle tool. In the quality of the percussion mechanism applied l vibrators.

However, tests of such a setup show that the principle of vibrating a packing tool with vibrator used in a machine does not provide the necessary performance and sufficient packing density.

The proposed equipment, in contrast to the known one, is equipped with an additional frame with a load, the impact mechanism is designed as a plunger hydraulic cylinder with a drive mounted on the base, rigidly connected to the housings of the power cylinders.

The body of the plunger hydro-cylinder is spring-loaded relative to the base and connected to an additional load-carrying frame, and the plug is rigidly connected to the padding tool through a platform connected at one end to the hinge with the additional frame, and load.

This constructive installation performance allows to improve the quality of the packing due to additional compaction by accumulating kinetic energy with a load, as well as to increase the productivity due to the accelerated compaction of the bottom mass.

FIG. 1 shows the proposed installation; in fig. 2 - then, side view; w FIG. 3 - impact mechanism; in fig. 4 - the same, side view.

Claims (1)

The unit has a self-propelled clutch, with (a frame frame 1, the rta of which is attached to {cylinders 2 and 3, with x: pi Y 1Ne between each other) CajjKoft 4, the beam 5 is rigidly welded to the beam 5 and hydraulic pump 7, as well as through crO 1C1tein 8 and hinge 9, pad 10, to which hydrocahiliidr 12 is rigidly attached with its plunger 11 12. Hydraulic cylinder casing is connected to the valve; new 5 by means of spring 13. An additional frame is housed through hinge 14 15 with i pyaoM 16, jointly movably with.corsus gi.drotsilin core 12, the other end of frame 15 is connected to pad 10 by a flexible Even 17. The same flexible link 18 connects pad 10 to the base 5. Hydraulic pump 7 is connected to the power cylinders 2, 3 and hydraulic cylinder 12 at high pressure hoses, the installation works as follows After the installation of the coal blocks and ravings, the installation for stuffing the gaps is installed in the electrolyzer. The bottom of the container is poured into the longitudinal grooves to be packed, and then with the help of the force cylinders 2 and 3 drive 19; then it turns on) 8 the operation of the hydraulic pump 7, which drives the installation drive and the percussion mechanism. The fitting does not move along the schv and the disk 19 seals the bottom mass as follows. The oil from the hydraulic pump 7 periodically (H1I51MI pushes into the cavity above the plunger 11 of the hydraulic cylinder 12, as a result of which the plunger 11 of the hydraulic cylinder 12 and, consequently, the pad 10 with the disc 19 fixed on it, begins to move downwards, the bottom mass is compacted. As soon as the necessary miot is reached the bottom mass, v.4. when the disk on the disk exceeds the force of the spring 13, the gifslider body 12 quickly moves relative to the platform 1O up, compressing the spring 13, but since the hydraulic cylinder body 12 is movably connected to the additional frame 15, it He leans behind himself and the frame 15 together with the load 16 giving the load an accelerated upward motion. Due to the accumulated kinetic energy, the load moving upwards, by means of the flexible link 17, moves the pad 10 along with the disk 19, additionally compressing the spring 13. Thereafter as the load completely consumes the accumulated energy, the pin 13 returns abruptly; the hydraulic cylinder 12 together with the platform Yu and the disk 19 downward, thus performing the impact of the disk 19 on the bottom mass and additionally compacting it, the force of the impact being summed up from the energy of the spring 13 and the kinetic tion power load 16, kotiran builds up when you move it down. Then the cycle repeats. The described ycrctHOBKa pvyshyvaet productivity by 2 times and improves the quality of stuffing. The invention The installation for stuffing the bottom of the bottom of the aluminum electrolysis cell, containing a frame of a self-propelled carriage with power shields installed on it, is equipped with a shock mechanism associated with a padding tool, in order to improve the quality of the packing, and to improve the quality of the packing. an additional frame with a load, the percussion mechanism is made in the form of a plunger gffok.ilder with gfivodom installed on the base, rigidly connected with the housings of the power cylinders, while KGpnyc lunzhernogo pedrotsilindra dammed neV relatively "hgnseani and is bonded to more rayuy and plugchgker .so gesture is associated with the stuffing tool osredstyom ploschadan associated with one Kovda doaolsh Yelnia frame and drugims load.
