Abstract

The invention relates to a grate cooler used in the production of cement and other building materials. The aim of the invention is to ensure reliable regulation of the air supply. Shiberny device contains installed in. body 1 a gate 2, made in the form of a rectangular sheet fixed on axis 3 with a handle, can be rotated relative to the body. The gateway 2 is made with a window 5 and is equipped with a bottom 6 that overlaps the window from the side, one side of which is hinged, and the other side with limited rotation. The hinged gate 6 eliminates the accumulation of clinker spilling onto the gate 2, ensuring the free rotation of the gate 2 relative to the axis. This ensures reliable regulation of the air supply of an acute blow. 1 hp f-ly, 2 ill. y (L ig. G

Description

This invention relates to structural elements of a grate cooler used to cool bulk material discharged.

from the rotary kiln, and there may be a gap between them. Grooves 10 by

it is used in the construction materials industry and in the metallurgical industry.

The purpose of the invention is to provide reliable control of the air supply to the section for the sharp blowing of the grate cooler.

Fig, 1 shows the proposed device, a longitudinal section; in fig. 2 is a view A of FIG. one.

The gate device includes a housing 1, a gate 2, made in the form of a rectangular metal sheet mounted in housing 1 on axis 3 with a handle 4. Gate 2 has a window 5. On the side, a gate 6 attached to the gate with one with the help of a hinge 7, and on the other hand, it is provided with an angle limiter 8 set to. the bottom surface of the gate 2. The limiter 8 rotation in the form of a pin is pressed against the gate springs 9. The grooves 10 in the valve 6 give the opportunity

The proposed design of the vane prevents the spillage 11 from blowing sharply and gating 2 from accumulating in the volume. This allows any vane 2 to be installed in the housing 1 in a certain position in accordance with the thickness of the clinker layer above the furnace 11 sharp blowing and thus differentiate the air supply sharp blowing, creating the same aerodynamic resistance along the length of the grate 11 sharp blowing. This facilitates the task of creating a fluidized bed above the grate 11 sharp blowing, which improves the uniform distribution of clinker across the width of the refrigerator, creates better conditions for heat exchange between the clinker and the air blowing sharp and, to some extent, the heat exchange between the clinker and the general air blowing that. povyshaet

open the spring 9, 30 the temperature of the secondary air and the bottom. rotated relative to the hinge 7. clinker temperature is on the way

Shibernoe device works as follows.

When operating a grate cooler, for example, of the Volga type, the clinker is distributed in an extremely uneven thickness across the width of the loading shaft on the fixed sections of the grate 11 sharp blow. Depending on the thickness of the clinker layer over each section of the grate 11, the gate 2 is set using the handle 4 in a certain position. Fix the position of the handle with a pin (not shown).

If the layer of clinker on the section of the grate 11 is small or almost absent, then gate 2 must completely overlap the cross section of housing 1. At this position of gate 2, the clinker, spilling through the slots of the grate 11, hits the gate 2. The compression force of the spring 9 is chosen so that the thinning of spillage on gate 2, flap 6 opens by turning

from chill nick a.
