Description

Rotating mechanism applied to disc type independent air supply circular cooler
Technical Field
The utility model relates to an iron-making sintering equipment technical field specifically is a rotary mechanism who is applied to cold machine of disk independent air supply ring.
Background
In iron and steel production enterprises, sintering is one of iron-making production processes, and the process is to mix powdery mineral powder and coke powder and then use a sintering machine to enable the mixture to be granular with a certain size so as to facilitate smelting. The sintered ore passing through the sintering machine is cooled mainly by an air cooling machine below. At present, the cooling machine adopted by iron and steel enterprises has two forms of a belt cooling machine and a circular cooling machine. The circular cooler is a circular cooler for short and is used for effectively cooling hot sintered ore discharged from the sintering machine. Compared with a belt cooler, the circular cooler has the advantages of small occupied area, investment saving, high equipment utilization rate and the like. However, the circular cooler trolley moves circularly and has a large turning radius, so that the movement rule of the circular cooler trolley is complex compared with the linear movement of the belt cooler trolley, the phenomenon of trolley deviation is easily caused in the operation process, the edges of trolley wheels bite the edges of steel rails, the trolley body extrudes and abrades sealing rubber, the current of a motor is increased, and other faults occur. These phenomena affect the normal operation of the circular cooler and the cooling effect of the sinter.
The working principle of the existing circular cooler is as follows: the driving device consists of two sets of transmission systems which form an angle of 162 degrees with each other. Each system consists of a motor, a speed reducer, a driving friction wheel and a driven friction wheel. It features that the two systems are identical to provide the same power and motion. The two systems are both hung on a fixed portal frame, and the whole transmission system can rotate a little around a shaft on the portal frame to absorb the vibration of the revolving frame in the operation process. The friction plate connected to the rotary frame via screws can move circularly around the inner and outer horizontal tracks under the drive of the friction wheel. The trolley body of the ring cooling machine is connected to a rotary frame through a hinge, and after receiving the red-hot sinter ore unloaded from the ore feeding hopper in a material receiving area, the trolley body moves circularly along a horizontal circular track along with the rotary frame. In the ore unloading area, the horizontal circular track is changed into a curved track which is bent downwards, the bottom plate of the trolley body filled with the sinter inclines along the track of the curved track, and the cooled sinter is unloaded from the discharge hopper, so that a cycle is completed.
The existing circular cooler has the following problems:
(1) and air leakage problem: the effective airflow path of the circular cooler is from the gap of the grate to the material layer of the trolley and then to the fan through the sealing cover until the material is exhausted to the atmosphere through the chimney. The air leakage part is mainly concentrated at the inlet and outlet ends and between the two side breast boards of the trolley and the sealing cover above the side breast boards. The most serious and difficult to be radically treated in production is the air leakage between the two side breast boards of the trolley and the sealing cover above the side breast boards. Because the annular friction plate is easy to deform and is abraded for a long time at high temperature, the rubber sealing plate is easy to be torn or extruded off by the trolley breast plate, so that harmful cold air enters the annular cooler to generate air leakage.
(2) The material distribution of the trolley is uneven: because the platform truck bottom surface of ring cold machine is fan-shaped, and distribution funnel and chute are difficult for making the loading line transversely perpendicular with platform truck breast board, and the unloading is unbalanced, and the material flow is unstable, and the material on the event platform truck distributes inhomogeneously, causes convulsions short circuit phenomenon outstanding, and cooling efficiency reduces.
