Special apparatus for replacing spraying-blowing fluidization plate

Abstract

The present invention discloses a special apparatus for replacing a spraying-blowing fluidization plate. The special apparatus comprises a bracket, wherein a lifting device is arranged on the bracket, and comprises a hydraulic cylinder, a chain and a lifting plate, the hydraulic cylinder is fixed on one side of the bracket, the lifting plate is arranged on the other side of the bracket, the pushing rod of the hydraulic cylinder is fixedly connected with one end of the chain, the other end of the chain bypasses a chain wheel arranged on the top end of the bracket, and is connected with the lifting plate, the lower end of the bracket is provided with a support bottom plate, and a walking wheel and a universal wheel are arranged on the support bottom plate. The special apparatus for replacing the spraying-blowing fluidization plate has the following characteristics that: operations are convenient, the mechanical device is adopted to replace human labor so as to reduce a maintenance and replacement time of the fluidization plate, reduce a coal feeding stopping time of a blast furnace, and ensure stable production of a blast furnace, maintenance labor is reduced, maintenance labor cost is reduced, and economic benefits are increased.

Description

technical field [0001] The invention relates to a special device for replacing a jet fluidization plate, which is a novel device for quickly replacing the jet fluidization plate. Background technique [0002] The injection of pulverized coal into ironmaking blast furnaces in the metallurgical industry is an important means for blast furnaces to increase furnace temperature, increase smelting strength, and reduce production costs. Due to the continuity and continuity of blast furnace production, the injection fluidized plate in the coal injection system will inevitably be damaged. When the fluidized plate is damaged, it needs to be replaced quickly, otherwise it will affect the injection stability and directly affect the blast furnace production. When replacing the fluidizing plate, due to the heavy mass and large volume of the fluidizing plate and the fluidizing chamber, manual replacement is difficult and requires a long maintenance time, which is time-consuming and labori...

AI Technical Summary

Problems solved by technology

When the fluidized plate is damaged, it needs to be replaced quickly, otherwise it will affect the injection stability and directly affect the blast furnace production

When replacing the fluidizing plate, due to the heavy mass and large volume of the fluidizing plate and the fluidizing chamber, manual replacement is difficult and requires a long maintenance time, which is time-consuming and laborious

Especially during unplanned maintenance and replacement, it is necessary to shut down the blast furnace for a long time, which seriously affects the stable and normal production of the blast furnace
