CS230628B1 - Grate bare cleaning device - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for cleaning grate bars, in particular sintering belts of agloaeration lines, and to the removal of physically strenuous and dangerous manual cleaning of these grate bars while improving the breathability of the suction surface.

When sintering the sintering mixture to the sintering belt, the grate surface is gradually clogged during operation by depositing the wood fractions between the individual slats.

Depending on the quality of the sintering mixture and other operating conditions, the grate surface is often glued and clogged in a short time, thus significantly reducing the permeability of the suction surface. In addition, some components of the agglomeration mixture did not melt when sintered by baking to the grates and so-called patches, which also reduce the efficiency of the suction surface. If the grate surface is not cleaned effectively, the conditions of the apékanals deteriorate, the quality of the agglomerate produced decreases, the specificity of the sintering belt decreases and its production, the fuel consumption increases and at the same time the energy consumption of the process increases.

The previously known grate cleaning method is difficult, time consuming and inefficient to manually pierce the grate surface by means of heavy bars. Manual cleaning is extremely laborious for the operator, requiring an increased number of staff and is performed only when the belt is taken out of service and the time utilization of the sintering line decreases. Since the grate surface cannot be sufficiently cleaned by hand cleaning, the described difficulties in sacking are repeated.

These drawbacks are eliminated by the cleaning device according to the invention, which consists essentially of at least one vibratory plate provided with a vibration exciter and associated hinges to the base of the seam belt.

The advantage of the adjustments according to the invention is that it removes physically strenuous and dangerous manual cleaning of the grates, ensures a more even sintering over the strip surface and improves the permeability of the suction surface. Tin vsroate quality 1 quantity of agglomerate produced at lower energy consumption for slatting of grate surface and higher life of grate. A further advantage is that the sintering strip is continuously poured into the full sieve, without the need for operator.

In the accompanying drawing, a schematic drawing of a set for cleaning scabbards according to the invention is already shown on the upper branch of the sintering belt. The sintering belt is drawn in section.

The device according to the invention in an exemplary embodiment consists of a vibrating plate 1 provided with a vibration exciter arranged on the upper branch of the sintering belt 1 in front of the hopper 6 of an agglomeration ash. The vibratory plate J is connected by a hinge 8 with the seam strip base χ.

The device according to the invention operates in such a way that the vibration exciter 1 causes the vibration plate to be knitted, but also allows the vibration plate 1 to move freely only vertically, while the horizontal movement of the hinge is reduced and further dampened by friction between the vibration plate 1 and the coil. The vibrations of the vibratory plate 1 cause adequate cyclic metal shocks, releasing both the individual grid and the adhering material therebetween.

The device according to the invention can also be used for cleaning the cut-off strips of power devices. By arranging several cleaning devices according to the invention side by side, the sintering strip 1 can be cleaned at will.
