End part sealing method of sintering machine

Abstract

The invention provides an end part sealing method of a sintering machine, and belongs to the technical field of sintering machine sealing. The end part sealing method comprises the use of an end part sealing device, and is characterized in that a sand outlet is formed at the front end of the end part sealing device; a sand dropping groove is formed at the back end of the end part sealing device; a sand table and a sand return channel are arranged between the sand outlet and the sand dropping groove; a sand conveying device is arranged, so as to enable the sand dropped into the sand dropping groove to return to the sand outlet of the sand table through the sand return channel and gush out upwards from the sand outlet; and meanwhile, the adoption of metal sand is recommended, so as to enhance the wind blocking ability of the end part sealing device. The end part sealing method suitable for end part sealing of the sintering machine has the advantages that the attaching effect of a sealing surface of the end part sealing surface, namely the upper surface of the sand and the bottom of a trolley can be effectively improved, air leakage of the sintering machine is reduced, the air quantity of a main air exhaust blower is decreased, the aim of energy conservation is achieved, the service life of the end part sealing device is prolonged, and the reliability, the maintainability of the end part sealing device are improved.

Description

technical field [0001] The invention relates to an end sealing method of a sintering machine, belonging to the technical field of sintering machine sealing. Background technique [0002] Sintering machine is a kind of equipment widely used in metallurgical enterprises. The air leakage rate of the sintering machine is generally as high as 50%, or even higher; among them, the air leakage at the end accounts for more than half of the total air leakage. The disadvantages of the end sealing device of the existing sintering machine are: [0003] 1. The bonding effect between its sealing surface and the bottom of the trolley is poor, which is the main reason for the large air leakage at the end of the sintering machine. [0004] 2. Its sealing surface slides relative to the bottom of the trolley. Due to the large number of trolleys, the sealing surface of the sealing device is severely worn; at the same time, the vulnerable part is not easy to replace and repair, which also cause...
