Air input system of ring cooling machine and ring air duct thereof

Abstract

The invention discloses an air inlet system of an annular cooling machine. An annular air duct consists of an annular liquid groove and a door-shaped sealing device; a sealing cover plate of the door-shaped sealing device covers on the annular liquid groove; an inner annular plate and an outer annular plate of a door-shaped air duct of the door-shaped sealing device extend downwards to the below of the liquid levels of an annular inner liquid tank and an annular outer liquid tank of the annular liquid tank respectively; the distance from an inner annular plate of the door-shaped air duct to an inner side annular plate of the annular inner liquid tank is larger than the distance from the inner annular plate of the door-shaped air duct to the inner annular plate of the annular air duct of the annular inner liquid tank; and the distance from an outer annular plate of the door-shaped air duct to an outer side annular plate of the annular outer liquid tank is larger than the distance from the outer side annular plate of the annular outer liquid tank to the outer annular plate of the annular air duct. The invention also discloses the annular air duct. The air inlet system can effectively prevent liquid in the annular liquid tank from splashing by overlarge vibration amplitude and ensures normal operation of the annular cooling machine.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to an air inlet system of an annular cooler and an annular air duct thereof. Background technique [0002] In iron and steel smelting, ring coolers are used to cool sintered materials. The ring cooler is in the shape of a ring as a whole, and the sintered material runs in the ring cooler for a week through a trolley to complete cooling and unloading. see figure 1 , is a radial (pointing to the center of the annular cooler) sectional view of the annular cooler 10, the main air duct 21 is connected to each branch air duct 22, the branch air duct 22 is connected to the annular air duct 23, and the outlet of the annular air duct 23 is connected to the inlet of the trolley. The air duct 26 and the trolley air inlet duct 26 are connected to the trolley 11 . [0003] The sintered materials are arranged on the grate plate 12 of the trolley 11, and the trolley 11 rotates around the ...

AI Technical Summary

Problems solved by technology

Known by Pt=mgh, this will cause the inner and outer liquid surfaces of the annular inner liquid tank 24A and the annular outer liquid tank 24B to vibrate up and down. If the vibration amplitude is too large, part of the liquid will enter the trolley (not shown in the figure) with the cold wind. Make the dust material stick on the grate plate (not shown in the figure) of the trolley, affect the ventilation of the wall plate, and also make the dust material on the lower plate (not shown in the figure) of the trolley stick on the lower plate, Affect the static seal of the trolley
