JPS5824926Y2 - Ventilation plate for sintered cooler trough - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation plate attached to a cooling trough of a sintered ore cooler.

The cooler of the DL type sintering machine has a trough 1 as shown in Fig. 1 arranged around the entire circumference of a circular rail (not shown), and sintered ore is poured into this trough from one end. During one rotation of the trough, the air sucked through the ventilation plate 2 on the bottom of the Nidraft cools the sintered ore, and the cooled sintered ore is discharged from the other end. .

The ventilation plate of the present invention is installed in order to provide ventilation holes necessary for cooling the sintered ore at the bottom of the trough when the cooler cools the sintered ore, and is arranged so that the ore does not fall from the hole. .

Figs. 2 to 5 show a conventional ventilation plate, and Fig. 6 shows an array cross opening when this ventilation plate is installed in a cooler trough.

In conventional ventilation plates, the processed parts at both ends are bent (I) in Figure 5 and drawn (6), and the shape is complicated, making it difficult to process, and the accuracy of the flatness of both ends is poor. Moreover, there was a lot of falling ore because there was no overlap between the ventilation plates (Fig. 6C).

The purpose of the present invention is to improve the above-mentioned drawbacks, to provide a ventilation plate that can be manufactured easily and accurately by simple bending, and that has a shape that allows the ventilation plates to overlap each other to prevent ore fall. .

FIG. 7 shows the steel plate of the present invention before processing.

Figures 8 to 10 show examples of the ventilation plate for a sintered cooler trough of the present invention.

The ventilation plate of the present invention is a long and narrow rectangular steel plate 3 as shown in Figure 7.
It is obtained by processing and molding.

In other words, point 4 located at a certain distance from both ends on the −long side
, 4a and is perpendicular to the long side of the straight line 45. 4a5a, convex upward along the straight line 45.
4a6a, the bottom surfaces of both ends of the steel plate after bending are on the same plane, and both ends of the long side on the points 4 and 4a are bent. This is a ventilation plate for a sintered cooler trough, which is made by cutting a steel plate 7 of a certain width by a certain length parallel to both ends 8 of the opposite side after bending and forming.

FIGS. 8 and 9 are a plan view and a vertical view of an embodiment of the ventilation plate of the present invention obtained by processing and forming the steel plate 3 shown in FIG. 7, and FIG. 10 is a view taken along arrow B-B in FIG. be.

Since the ventilation plate of the present invention can be formed by a simple bending process, it is possible to easily obtain an accurate and precise ventilation plate.

Furthermore, the ventilation plate of the present invention has a constant width cutout at both ends, so that when it is installed in the cooler trough as shown in Figure 11, the adjacent ventilation plate can be removed as shown in Figure 12. It is wrapped and arranged like this.

The width and length of the cutout portion 70 are determined in consideration of this wrap amount.

The cutout portion 7 may be cut out before or after the bending process in the manufacturing process.

The ventilation plate for a sintered cooler trough of the present invention is constructed as described above (1) It has good shape accuracy, and the ventilation plates overlap each other to prevent ore fall.

(2) The flat dust on the bottom surface is good, so it is firmly fixed and requires less maintenance later on.

(3) Easy to process.

There are advantages such as
