Description

technical field

The invention relates to blast furnace top equipment, more specifically, to a semi-closed high-pressure water cooling system for a distributor.

Background technique

Distributor is the key equipment on the roof of ironmaking blast furnace.

Two patents, CN202786285U and CN202786283U, propose a distributor based on trolley wires. This type of distributor fixes the tilting motor on the rotating cylinder, and the rotation and tilting of the chute are completely independent, which simplifies the installation of the gearbox of the distributor. The internal structure is simple and the control is more convenient. However, because the tilting motor of this type of distributor is placed inside the housing of the distributor, higher requirements are put forward for the water cooling system of the distributor. The existing cooling system has a large amount of waste water and poor cooling effect.
