AI Technical Summary
The sintering machine bellows compensator is squeezed and deformed due to thermal expansion and contraction, which cannot meet the production process requirements, resulting in equipment damage and increased air leakage rate.
The sintering machine bellows self-adjusting boom group structure is adopted, including concrete beam, hook, boom, connecting plate, cylindrical coil spring, gasket and nut. By tightening the nut, the tightening force of the cylindrical coil spring is made consistent, so that the bellows compensator is kept free from tension and compression, thereby achieving self-adjustment.
It avoids the extrusion deformation of the bellows compensator, ensures the normal operation of the bellows compensator, extends the service life of the equipment, and meets the production process requirements.

Abstract
Description
Technical Field
[0001] The utility model relates to a self-adjusting boom group structure of a sintering machine bellows, belonging to the technical field of metallurgical industry equipment. Background Art
[0002] During the sintering production process, when the empty trolley runs along the track to the bottom of the distributor at the head of the sintering machine, the base material and the sintering mixture are loaded on the trolley in turn. When passing through the igniter, the solid fuel in the mixture is ignited. At the same time, the vacuum chamber at the bottom of the trolley starts to evacuate air, so that the sintered ore is burned from top to bottom. The high-temperature waste gas during the combustion of the sintered ore is discharged from the sintering system through the sintering machine bellows and flue. The bellows compensator will compensate for the limited up and down movement of the sintering machine bellows pipeline system due to thermal expansion and contraction. Since the bellows compensator is installed under the sintering machine bellows, the bellows compensator has to bear the weight of the sintering machine bellows. Therefore, the bellows compensator is squeezed and deformed. However, the compensation amount of the bellows compensator is very small. In the actual production process, it cannot meet the limited up and down movement of the sintering machine bellows pipeline system due to thermal expansion and contraction, which may lead to damage to the bellows compensator or welding damage to the sintering machine bellows pipeline system, and even increase the air leakage rate of the sintering machine, making it unable to meet the sintering production process requirements.

[0005] A self-adjusting boom group structure for a sintering machine bellows comprises a concrete beam, a hook, a boom, a connecting plate, a cylindrical coil spring, a gasket, a nut, a bellows and a bellows compensator. The bellows compensator is installed under the bellows. Two connecting plates on the same horizontal plane are provided on the side of the bellows. Each connecting plate is provided with a circular hole that matches the boom. There are two booms, and the upper ends of the two booms are respectively hung on the hooks of the concrete beam, and the lower ends of the two booms are respectively passed through the circular holes of the two connecting plates, and are provided with cylindrical coil springs, gaskets and nuts.

[0007] The cylindrical coil spring is sleeved on the suspension rod between the connecting plate and the nut.
