Duct dredging device for steel slag hot braising pools

Abstract

The invention discloses a duct dredging device for steel slag hot braising pools, which relates to the technical field of duct construction of steel slag hot braising pools, and comprises a duct, wherein the duct is communicated with the steel slag hot braising pools through drainage ports; a water tank is arranged at the bottom of the duct; a steel slag chain scraping machine is arranged in the water tank and is provided with a rack; a drive sprocket and a guide wheel are mounted on the rack; an annular scraper chain is connected between the drive sprocket and the guide wheel; and the drive sprocket is connected with a power machine through a reducer box. Compared with the prior art, the duct dredging device for the steel slag hot braising pools can automatically clean out steel slag and powder in the duct, and enables the steel slag hot braising pools to work normally.

Description

technical field [0001] The invention relates to the technical field of construction of steel slag hot stuffy pool culverts, in particular to a device for cleaning the steel slag hot stuffy pool culverts. Background technique [0002] Steel slag is an inevitable by-product of the steelmaking process, accounting for about 10-15% of steel production. The rapid and effective treatment of steel slag directly affects the sustainable development of the steel industry. The treatment of steel slag is generally to put the high-temperature scrap steel slag transported to the slag yard into the steel slag heating tank, cover the steel slag after it is evenly heated in the tank, and use the water spray device on the cover of the heating tank to spray water intermittently to make the heat The slag is cooled. Under the action of thermal expansion and contraction, the large pieces of waste slag will be decomposed into small particles of waste slag. On the other hand, the chemical reaction b...

Problems solved by technology

[0003] 1. During the discharge of water, steel slag or powder smaller than the diameter of the filter mesh will enter the duct with the water. If the steel slag or powder cannot be discharged in time, the non-metallic oxides in the steel slag left in the duct will chemically react with water The formation of hard scale condenses on the duct wall, making the inside of the duct an alkaline environment. After a period of time, the duct will be blocked and the water cannot be removed, resulting in the failure of the steel slag hot stuffy pool to work normally.

[0004] 2. During the process of slag filling, water and high-temperature slag will undergo high-temperature gasification and decomposition, resulting in a large amount of high-temperature water steam containing hydrogen and oxygen. The reaction between high-temperature water steam and non-metals will produce carbon, sulfur, phosphorus, etc. Toxic gas permeates the duct, and it is impossible to dredge it manually
