Technical Field
[0001] The invention relates to the technical field of belt sintering machines, in particular to a trolley anti-air leakage grate pressing piece used for a trolley of a belt sintering machine. Background Art
[0002] The belt sintering machine is the main equipment in the sintering agglomeration process and is also one of the main equipment for providing raw materials for blast furnace agglomeration. During the operation of the belt sintering machine, the driving sprocket rotates and drives the trolley forward through the toothed plate. After the trolley is distributed, the ignition furnace sprays flames downward to ignite the fuel surface. Under the negative pressure of the suction device, the material is burned from top to bottom. After unloading at the tail of the sintering machine, the sintering operation is completed. The trolley flips over on the return lane and runs to the head to start a new distribution operation. In order to prevent the side bars from falling off during the trolley flipping process, the side bars are pressed tightly through the through-holes of the lower railing of the trolley by the bar pressing pins. Since the through-holes and the bar pressing pins are loosely matched, the air leakage is extremely large under the negative pressure of the sintering machine, which increases energy consumption and reduces the life of the railing.
[0003] Therefore, it is urgent to design a trolley anti-leakage grate bar pressing piece, which can be used for the belt sintering machine trolley and effectively control the air leakage of the grate bar pressing pin. Summary of the Invention
[0004] The purpose of the present invention is to provide a trolley anti-leakage grate pressing piece for a belt sintering machine trolley to solve the problem in the background art that the grate pressing pin has high leakage rate affecting the belt sintering machine and the sintering end point is difficult to control.
