Closed water cooling blast furnace top distributing gear based on rapid exchange oil cylinder

Abstract

The invention discloses a closed water cooling blast furnace top distributing gear based on a rapid exchange oil cylinder, which mainly comprises a rotary system for realizing the rotation of a chute, and a lifting system capable of repeatedly moving up and down along the axial direction of a central pipe, wherein the rotary system mainly comprises a rotation driving assembly, an upper pivoting support, a rotary cylinder and a suspension assembly, and the lifting system mainly comprises lift driving assemblies taking the rapid exchange oil cylinder as a drive mechanism, a lower pivoting support and a sliding case type ring. The lifting motion of the lifting system is finally transformed into the tilting of the chute and the suspension assembly, the rotation driving assembly is entirely arranged on a top cover of the shell of the distributing gear, and the lifting system is provided with three lift driving assemblies which are uniformly fixed on the top cover f the shell of the distributing gear. By adopting the distributing gear, the defects, such as complex exchange operation of hydraulic cylinders, hardness of the lubrication of the pivoting support in the distributing gear, the corrosion of the distributing gear due to cooling steam, overflow of cooling water in the blast furnace and the like can be overcome.

Description

technical field [0001] The invention relates to blast furnace metallurgical mechanical equipment, in particular to a closed water-cooled blast furnace top distributor based on quick-change oil cylinders. Background technique [0002] The distributor is the key equipment for the bellless top of the blast furnace. It realizes various distribution forms in the furnace throat through the rotation and tilting of the chute, so that the charge is reasonably distributed on the material surface, and the thermal energy and chemical energy of the blast furnace gas are fully utilized to achieve smooth production and improvement of the blast furnace. purpose of efficiency. [0003] Bellless blast furnaces at home and abroad basically use "PW-type planetary differential transmission distributor", which has the advantages of flexible and diverse distribution methods and uniform distribution, but with the wide application of this type of distributor, its shortcomings are increasingly expose...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the main purpose of the present invention is to provide a blast furnace roof distributor based on quick-change oil cylinders and closed water cooling technology to solve the complicated operation of hydraulic cylinder replacement, difficulty in lubrication of the slewing bearing inside the distributor, and cooling water vapor corrosion of the distributor. Defects such as device, cooling water overflow into the blast furnace, etc.
