Steel slag ball production equipment and water tank cooing system thereof as well as method for cooling steel slag ball

Abstract

The invention discloses steel slag ball production equipment and a water tank cooing system thereof as well as a method for cooling a steel slag ball. A cooling water tank comprises a tank body which is used for containing cooling water and is provided with an opening at the top; a discharging opening for water and the steel slag ball to flow out is arranged at the lower part of the front end of the tank body; the bottom surface of the tank body is a slope surface which is gradually reduced from rear to front relative to a horizontal plane; a screen which allows the water to flow through and can intercept the steel slag ball is arranged above a water discharging opening in a material storage cabin; a cabin wall of the material storage cabin is further provided with a discharging opening which corresponds to the screen and is used for enabling the steel slag ball to be discharged out from the material storage cabin; a water storing tank is arranged opposite to the water discharging opening of the material storage cabin; and a water pipe and a water pump which are used for pressurizing the water in the water storing tank and pumping the pressurized water into the cooling water tank are connected between the water storing tank and the cooling water tank. The water tank cooing system of the steel slag ball production equipment disclosed by the invention can automatically flush the water and discharge the materials and used cooling water can be purified and circularly used; and the production capability is great, the cost is low and a large quantity of water sources can be saved.

Description

technical field [0001] The invention relates to equipment for processing waste steel slag or high-temperature liquid steel slag into steel slag balls for industrial application. Background technique [0002] A large amount of steel slag will be produced in the steelmaking process of converter, smelting furnace or electric arc furnace. For example, in the process of refining steel in converter, steel slag with high non-metal content will be produced. These steel slags must be gradually discharged from the furnace during smelting. According to the latest statistics, the amount of steel slag in my country was about 80 million tons in 2010, and the utilization rate of steel slag was only about 10%, which is still far from the goal of "zero" discharge of solid waste by Chinese enterprises. The discharge of a large amount of waste steel slag not only occupies a large amount of arable land, but also pollutes the environment. Therefore, the recycling of steel slag has become a socia...

AI Technical Summary

Problems solved by technology

In this type of steel slag processing equipment in the prior art, the liquid steel slag flowing out of the launder lacks matching with the injection of high-speed water and air flow. In addition, the fluidity of the steel slag is poor and the distribution of the steel slag flow is uneven, resulting in incomplete granulation of the steel slag balls, spherical shape not good

In addition, the pools in the prior art can only take out the steel slag balls by digging after draining, which has low work efficiency, high labor intensity and serious waste of water resources, and the steel slag balls are easily eroded by harmful substances in the water during the accumulation process in the pool And reduce the quality of steel slag ball
