JPS5929947Y2 - Forced draft type cooler air seal device - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an air seal device for a forced draft type cooler.

As shown in FIG. 1, the forced draft cooler 1 installed in sintering equipment includes a number of troughs 3 connected in an endless circular shape and movable in a fixed direction on a rail 2;
a blower (not shown) that sends cold air 4 from below to above;
It consists of an air chamber 5 provided below the trough 3 and a hood 6 provided above the trough 3.

The sintered ore was placed on the trough 3 and cooled by cold air 4 passing through the trough 3 from bottom to top.

Incidentally, since the hood 6 is fixed while the trough 3 moves, a sufficient gap is provided between the trough 3 and the hood 6 in consideration of smooth movement of the trough 3.

In order to prevent cold air from escaping through the narrow gap, air seal plates 7 as shown in FIG.
A gap a is absolutely necessary to prevent contact with the
Therefore, loss of cold air could not be prevented.

Therefore, the present invention provides a sealing device that can almost eliminate the loss of cold air from the gap between the trough and the hood.

An embodiment of the present invention will be described below with reference to FIG.

Numeral 11 is a trough which is connected in a large number in an endless circular shape and is moved in a fixed direction; 12 is a fixed hood provided above the trough 11; and 13 is between the side wall 11a of the trough 11 and the side wall 12a of the hood 12. This is a sealing device installed in the

The seal device 13 is located between the lower hood side wall 112b and the upper surface 11b of the trough side wall, and is located between the lower hood side wall 112b and the upper surface 11b of the trough side wall.
A support plate 15 is swingably supported on the lower surface 12b of the hood side wall as shown by arrow A via a shaft 14 in a horizontal direction and substantially parallel to the shaft 14; A flexible first sealing material (1) having one end fixed to the support plate body 15 via a bolt 16 and the other end fixed to the upper surface 11b of the trough side wall via a bolt 17;
For example, rubber, asbestos, etc. are used, and an appropriate material is selected depending on the cooling section and waste heat recovery section.

) 18, a second sealing material (for example, SS material) 19 attached to the support plate body 15 and made slidable on the upper surface 11b of the trough side wall, and the second sealing material 19
A counterweight 20 is attached to the support plate body 15 at a position closer to the outside than the counterweight 20 for pressing the second sealing material 19 against the upper surface 11b of the trough side wall.

The counterweight 20 is attached to the hanging portion 15a of the support plate body 15 via a bolt 21, and the bolt hole 15b drilled in the hanging portion 15a is formed into an elongated hole in the width direction of the trough 11.

Therefore, by moving the counterweight 20 in the direction of the arrow B, the pressing force of the second sealing material 19 against the upper surface 11b of the trough side wall can be adjusted.

According to the above configuration, when the cooler is operated, if the second sealing material 19 is pressed onto the moving trough side wall upper surface 11b with a force that does not prevent its sliding,
Cold air can be prevented from escaping from the gap between the upper surface 11b of the trough side wall and the lower surface 12b of the hood side wall.

Furthermore, even if the upper surface 11b of the trough side wall fluctuates, the support plate 15 that supports the second sealing material 19 is able to swing in the direction of the arrow A by discontinuing the shaft 14. Can follow.

In FIG. 3, the sealing device 13 of the present invention has been described with respect to one side of the trough 11, but it goes without saying that the sealing device 13 is provided on both sides of the trough 11, and the cooling portion of the trough 11 is cooled. It is not even a case that it is provided all the way around.

As described above, according to the forced draft cooler air seal device of the present invention, it is possible to completely seal between the soil surface of the trough side wall and the lower surface of the hood side wall, which could not be sealed conventionally, and in particular, the second seal Since a counterweight is provided that supports the material via the swingable support plate and presses the second sealing material against the upper surface of the trough side wall, even if the upper surface of the moving trough side wall fluctuates, the second sealing material The sealing material can follow these fluctuations.
