BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side wall seal plate for a sinter pallet truck.

[0002]

2. Description of the Related Art The side wall of a sinter machine pallet truck is for holding the sintering raw material and smoothly performing the sintering reaction. Since it is ignited and then air is sucked from below the pallet truck of the sintering machine, it is heated from the raw material located on the upper part of the side wall, and the red tropical zone of the sintered ore is sequentially in the lower part until it is discharged. It moves and sinters, and is further cooled from the discharge ore to the ore supply. Since heating and cooling are repeated, the sidewalls are deformed due to thermal stress due to extremely severe use conditions. There was a problem that cracks were likely to occur.

For this reason, a two-divided or three-divided type sidewall has been used to deal with deformation and cracking. However, in the conventional divided type sidewall, it is necessary to provide a gap between the sidewalls, and heating is required. Considering the thermal expansion at the time, a gap of about 2 to 4 mm is unavoidable in manufacturing. When it is used for a longer period of time, the gap tends to gradually increase due to the deformation and shrinkage of the side wall, and the outside air is sucked in from the gap during operation, and the air suction force in the necessary portion is reduced, and therefore the sintering efficiency is improved. Along with the decrease, there was a large loss in terms of power consumption due to useless suction of outside air, which had an adverse effect.

Therefore, in order to prevent air leakage due to the deformation of the sidewalls, a seal plate having a long hole in which the downstream side is inclined downward in a central portion in the height direction is interposed on the outer surface of the downstream end portion of the sidewall. , There is a proposal that a pin is fixed to a side wall so as to be loosely fitted in the long hole to close a gap generated due to deformation of the side wall (for example, Japanese Utility Model Laid-Open No. 55-144997).
See Japanese Utility Model Publication No. 3-5839).

[Problems to be Solved by the Invention] Saikai 55-14
According to those disclosed in Japanese Patent Publication No. 4997 and Japanese Utility Model Publication No. 3-5839, the seal plate can be slanted downward by its own weight to close the gap between the sidewalls due to thermal deformation of the pallet sidewalls. However, there is a problem that air leakage occurs from the downward movement allowance of the seal plate due to the downward movement of the seal plate, for example, a lower gap of 5 to 10 mm.

An object of the present invention is to provide a side wall seal plate in a sinter machine pallet truck that solves the above problems.

[0007]

In order to achieve the above object, the present invention provides a seal metal article having a long hole on the lower outer surface of a seal plate slidably provided at a downstream end of a sidewall so as to be slanted downward. The gist of the present invention is to provide a side wall seal plate in a sinter machine pallet truck, which is vertically movably attached by a guide pin through the elongated hole.

[0008]

Operation and Embodiments The present invention will be described below based on the illustrated embodiments.

In the present invention, as shown in FIGS. 1 and 2, a seal plate 3 is slidably downwardly mounted on a downstream end 1A of a sidewall 1 (hereinafter referred to as a sidewall) of a pallet truck. It is characterized in that a seal metal piece 6 having a long hole 7 is attached to the lower outer surface of the seal plate 3 so as to be vertically movable via a guide pin 8 loosely fitted in the long hole 7. In the figure, 2 is a pin fixing member, 4 is a fastener for the pin fixing member, and 5 is a pin.

The seal plate 3 is shown in FIGS. 3 (a) and 3 (b).
As shown in FIG. 5, the slanted long hole 9 of the seat plate 3 provided in a slanting downward direction is provided with the pin 5 at the downstream end 1A of the sidewall.
Are attached by loose penetration. That is, since the pin 5 is fixed downward to the sidewall end portion 1A, if a gap is formed at the sidewall end portion, the seal plate 3 is attached by its own weight along the inclined elongated hole 9 so as to eliminate the gap. To move. With this movement, the seal plate 3 also moves downward, so that the amount of downward movement of the seal metal 6 according to the present invention is reduced by the long hole 7.
The upper end of the seal plate 3 is always in contact with the sidewall mounting flange 10 by this movement, and air leakage from between the seal plate 3 and the sidewall mounting flange 10 is prevented.

[0011]

As described above, according to the present invention, it is possible to prevent the gap at the lower end portion of the seal plate due to the movement of the seal plate of the sidewall, so that the power consumption at the time of sintering is reduced and the yield of the sintered ore is reduced. It is possible to improve the thermal efficiency and to improve the thermal efficiency, prevent gas cutting of pallets due to air leakage, and reduce maintenance costs.
