[0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants, and is mainly suitable for the sintering treatment of iron ore powder in large and medium-sized sintering plants.

[0003] During the use of the sintering machine, a head and tail sealing device of the sintering machine is required. The end sealing device of the sintering machine is mainly used to control air leakage between the bellows at the head and tail of the sintering machine and the bottom beam of the trolley. The purpose is to overcome the shortcomings of the existing technology and provide a new sealing device, which can effectively realize the sealing of the head and tail of the trolley, reduce air leakage and reduce energy consumption.

[0004] However, in the prior art, the elastic support system inside the head and tail sealing devices of most sintering machines is prone to spring failure after long-term use, resulting in panel collapse, side air leakage and other problems. Utility Model Content

[0009] The floating sub-box includes an upper box mounting plate, an upper box steel plate fixed to the bottom side of the upper box mounting plate, an upper fixing plate of the spring device and limit plates fixed on both sides of the bottom of the upper box mounting plate. A wear-resistant plate is fixed on the top surface of the upper box mounting plate. The limit plates are vertically arranged and extend into the cavity surrounded by the box steel plates to ensure that the floating upper box and the box-shaped base can move freely up and down. The upper and lower ends of the spring device are respectively connected to the upper fixing plate of the spring device and the lower fixing seat of the spring device.

[0010] Preferred technical solution three: The side sealing assembly includes a U-shaped plate, a sealing cloth, and an insert plate. The U-shaped plate port faces downward and the top end is fixed to the upper box mounting plate. The insert plate and the sealing cloth are fixed to the ear plate by a set of fixing bolts and a pressure plate, and the sealing cloth is attached to the insert plate and inserted into the U-shaped plate from the bottom end of the U-shaped plate along with the insert plate.
