The invention relates to mechanisms and devices used in coke production, in particular, to a device for leveling coal charge in a coking chamber.

The purpose of the invention is to improve the quality of the produced coke, to increase the productivity of the coke oven and to reduce the metal intensity of the planned 1 bar.

I Figure 1 shows the device, a general view, the case is fully extended - | Tre bar from the furnace); in figure 2 - the same, just slid as far as possible -. rod in the furnace in fig.Z - section in figure 2.

The device for leveling and compacting the charge in a coke oven consists of a horizontal platform 1, racks 2 mounted on it with guide rollers 3 in which the planned rod 4 is located. To the two front racks there are attached kongateyn 5 on which are made rectangular permanent magnets 6. On the upper non-furnace part of the planned stretch 4 | Length L, a permanent magnet | 7 is reinforced, made in the form of a profile tape with a uniformly varying height p. Moreover, magnet 7 does not occupy the entire {width of the planning rod S, but only the fee is not the supporting part i, the permanent magnets 6 are also equal in length, the distance h between the magnets 6 must take a multiple of the step of the profile tape t. On the first two poles, the guide zoliki 3 is fixed in sliders 8, pressed by spring 9. All three magnets have the same pole.

The device works as follows.

Initially, the movement of the rod 4 From the initial position (Fig. 1), only happens in the horizontal direction. The interaction between the magnets 6 and the upper part of the planning pant Gui 4 is absent, due to the considerable distance 1 between them. When the first protrusion of the magnet 7 will be under the first in the course of the rod. the furnace is magnet 6, then the distance 1 between them becomes small and between the magnets having the same poles, the repulsive forces are generated. Since the magnets 6 are connected rigidly through. zhronshtey 5 with fixed rack- № 2, and the magnet 7 is rigidly connected to

By planning rod 4, which moves along rollers 3, spring-loaded on the first two pillars 2, the repulsive forces between magnets 6 and 7 move the planned rod 4 down. As the rod 4 moves further into the furnace, the protrusion is replaced by a depression and the repulsive force decreases and the rod moves up again and so on. As the rod 4 moves in the furnace, the area of its contact with the charge increases, which also requires an increase in the vibration effect. The latter occurs when the first protrusion of the magnet 7 is under the second magnet 6 along the bar in the furnace. Depending on the step t, the oscillation frequency of the bar and its amplitude can be changed. A similar process is observed in the reverse double-fold of the planning shaft 4 of the furnace.

Thus, the use of a device for leveling and compacting the charge in a coke oven using a vibration mechanism, which is in the form of permanent magnets, improves the quality of the produced coke and increases the productivity of the coke oven by equalizing and increasing the density of the charge over the length of the coke oven. and also allows to reduce the metal intensity of the planar shtangi due to the use of vibrators - and other elements from it.
