Description

Fourth generation grate cooler with cross airflow cooling grate bed

Technical Field

The utility model relates to a fourth generation grate cooler with alternately airflow cooling grate belongs to cement manufacture equipment technical field.

Background

The stacking grate bed of the grate cooler of the fourth generation is positioned in the grate cooler and is a part for continuously stacking and cooling the high-temperature clinker after being cooled by the fixed bed, and a grate plate with a ventilation groove is arranged in the grate bed. The wind of the cooling fan is blown into the upper surface of the grate bed from the wind chamber below the grate bed through the wind grooves or wind tunnels on the grate plate, and the clinker accumulated on the upper surface is cooled. In normal operation, clinker is always accumulated on the grate bed provided with the grate plate, moves along with the grate bed in a stepping structure, and is pushed forwards by a pushing rod in a pushing rod structure. The clinker is accumulated on the grate bed for a longer time, so the cooling air acts for a longer time, and the cooling efficiency is improved.

However, in general, when the grid plates are installed on the movable grid plates, the direction of the wind blown out by the ventilating slots on each grid plate is the same, or is perpendicular to the moving direction of the grid bed, or is the same with the moving direction. In the blowing cooling condition, when the clinker is in a large block shape and the clinker blocks on two sides are extruded together, the cooling air can not be blown to two side surfaces of the clinker easily. Particularly, the clinker stays on the grate bed for a relatively long time, gaps among the clinker are easily compressed to be small, the ventilation air volume of the ventilation grooves of the grate plates is reduced, and the blowing-through effect of cooling air is influenced. And then the ventilation resistance is increased, so that the cooling effect is lowered.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the fourth generation grate cooler with the crossed airflow cooling grate bed can overcome the defects, and the structure can cool the clinker piled on the grate bed by cooling wind in the crossed direction in the process of being driven to move. The cross cooling wind can disperse the long-time accumulated clinker, increase the gaps among the clinker, improve the passing efficiency of the cooling wind, improve the cooling efficiency of the clinker and reduce the ventilation resistance.

Grate cooler is taken place to fourth generation with alternately air current cooling comb bed, including fixed comb bed and windrow comb bed, be provided with the structure that promotes or drive the grog and remove on the windrow comb bed, fixed comb bed end-to-end connection windrow comb bed installs the comb board that has the bar air channel on the windrow comb bed, the bar air channel have the direction of arrangement of two kinds of differences.

Furthermore, the strip-shaped ventilation slots in the two different arrangement directions are perpendicular to each other or have other crossing angles.

Wherein, the arrangement directions of the strip-shaped ventilation grooves on the same row of grid plates on the stacking grid bed are the same.

Preferably, the grid plates of different rows are arranged in the manner of ABAB.

Preferably, the grid plates of different rows are arranged in the manner of AABAAB.

The utility model discloses can make the grog of piling up on the comb bed cooled by the cooling air on two or more directions, improve the utilization ratio of cooling air, at the removal in-process that activity comb bed or promotion stick promoted, accumulational grog can form the not hard up cooling effect of cross air current because the draft slot ventilation direction is different on the comb board. And the cooling efficiency is improved.

Compared with the prior art, the utility model beneficial effect who has is:

the utility model discloses can make grog be cooled by the cooling air on a plurality of directions, improve the utilization ratio of cooling air, not hard up grog of piling up together, at grog removal in-process, the air feed volume in comb board ventilation groove also can be because the not hard up and the clearance increase of grog and ventilate stably.

Drawings

Fig. 1 is a schematic top view of the present invention.

In the figure: a fixed grate bed 1; a stockpiling grate bed 2; a grid plate 3; a strip-shaped ventilation slot 4.

Detailed Description

The invention will be further described with reference to specific examples. The use and purpose of these exemplary embodiments are to illustrate the invention, not to limit the scope of the invention in any way, and not to limit the scope of the invention in any way.

As shown in figure 1, the grate cooler with cross airflow cooling grate of the fourth generation comprises a fixed grate 1 and a stacking grate 2, wherein the stacking grate 2 is provided with a structure for pushing or driving clinker to move, the end of the fixed grate 1 is connected with the stacking grate 2, a grate plate 3 with a bar-shaped ventilation slot 5 is arranged on the stacking grate 2, and the bar-shaped ventilation slot 5 has two different arrangement directions.

The two strip-shaped ventilation slots 5 in different arrangement directions of the embodiment are perpendicular to each other and are divided into horizontal and vertical directions.

In this embodiment, the arrangement directions of the strip-shaped ventilation slots 5 on the same row of grid plates 3 on the stacking grid bed 2 are the same, and the grid plates 3 in different rows are arranged in an AABAAB manner, but can also be arranged in an ABAB manner or other manners.

The cooling air blown out from the strip-shaped ventilation slots 5 on the grid plate 3 of the embodiment forms cross air flow, and the clinker is cooled by air flow from a plurality of directions. The clinker aggregate dispersing device has the advantages that the clinker aggregate accumulating for a long time can be dispersed, gaps among the clinker aggregate are increased, the passing efficiency of cooling air is improved, the cooling efficiency of the clinker aggregate is improved, and the ventilation resistance is reduced.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
