Abstract
Description
Technical Field
[0001] The utility model relates to a steel slag processing device, in particular to an environmentally friendly steel slag processing device. Background Art
[0002] During the metallurgical and casting processes, a large amount of solid waste such as steel slag is generated. This steel slag solid waste has an extremely high temperature.
[0003] For this type of slag treatment process, water cooling is usually adopted. For example, the desulfurized slag is treated with a hot tank method. The desulfurized slag is kept hot in the tank and water is continuously pumped in the tank to cool it down and pulverize it, making it easier for subsequent processing.
[0004] For the casting slag, a slag pool is built, and a process of pumping water into the slag pool to cool the slag is also adopted to cool the slag and crush it.
[0005] In the existing slag suffocation process, it is usually necessary to use a water pipe hung on the edge of the slag tank mouth by manual hand-held hanging pipes to pump water. Personnel are required to hang and remove the pipes before and after pumping water. Since the height of the slag tank and the tank base is too high, there is a safety risk of falling and injury for the operators; the boiling water in the tank is easy to splash out and scald the operators who take out and hang the pipes; the slag accumulated on the tank wall and in the tank has a safety risk of falling and being dragged out to injure the operators, making operation difficult for personnel.
[0006] CN214300212U discloses a device for pumping slag from a tank. It comprises a column, a sleeve, a roller, a vertical pipe, and a horizontal pipe. The sleeve is connected to the column via a connecting rod. The roller is mounted within the sleeve. A bracket is provided on the roller, and the vertical pipe is mounted on the bracket. The horizontal pipe is connected to the vertical pipe. The vertical pipe is parallel to the axis of the roller, and the horizontal pipe is perpendicular to the axis of the roller. The roller and sleeve form a rotational connection, allowing the horizontal and vertical pipes to rotate about the axis of the roller. A rotating handle is provided on the bracket. This utility model utilizes a mechanical transmission structure, eliminating the need for direct operator operation of the pumping pipe, reducing operational difficulty and risk for operators.
[0007] However, this device still requires a relatively complex transmission system and cannot reflect the process of pumping water in a closed space. Open water pumping is also prone to causing problems such as steam waste and dust pollution. Utility Model Content
[0008] In order to solve the technical problem of automatically pumping water in a closed slag-blocking space, the utility model provides an environmentally friendly steel slag-blocking slag treatment device.
[0009] The technical solution to realize the utility model is a steel slag environmentally friendly slag treatment device, including a slag stifling device, a cover body, a traction bracket, a traction device, a cover body bracket, a spraying device, and a dust removal device. A cover body bracket is provided on one side of the slag stifling device, a traction bracket is provided on one side of the cover body bracket, the upper part of the cover body bracket is hinged to the cover body, a spraying device is provided in the cover body, and a dust removal device is provided on the upper part of the cover body. The height of the traction bracket is greater than the slag stifling device.
[0010] Furthermore, the traction device includes a winch located at the lower part of the traction bracket and a pulley located at the upper part of the traction bracket. The winch is connected to the cover body through a steel wire rope passing through the pulley.
[0011] Furthermore, the spray device includes a spray pipe located at the lower part of the cover body, a plurality of spray holes are opened on the spray pipe, and the end of the spray pipe is connected to a water pump.
[0012] Furthermore, the dust removal device includes a dust removal adapter, the lower part of the dust removal adapter passes through the cover body, the upper part or the side of the dust removal adapter is connected to the dust removal pipe, and the end of the dust removal pipe is connected to the induced draft fan.
[0013] Furthermore, the slag-smothering device is a slag-smothering pool or a slag-smothering tank.
[0014] Slag stagnation pools are used to treat casting slag. They can be constructed on the ground with drainage facilities at the bottom, a refractory layer on the walls and bottom, and a layer of steel billets. A liftable (or folding) curtain is installed on one side, controlled by a lifting mechanism. They are particularly suitable for handling large quantities of slag. The slag is transported to the slag stagnation pool by forklifts and other means, where it is cooled by spraying water. The resulting steam and dust are then absorbed and discharged through a dust removal system.
[0015] The slag tank is used to process desulfurization slag. The tank is hoisted to the slag tank location by an overhead crane. The tank lid is now open. Once the tank is in place and secured, a relatively enclosed space is created for watering, cooling, and digestion operations. Upon completion, the lid is opened and the slag tank is hoisted by a crane to the treatment area, completing the desulfurization slag treatment process. The entire treatment process takes approximately 10 hours. The high-temperature desulfurization slag is rapidly cooled and shattered upon contact with water, generating a large amount of steam. This steam accelerates the digestion of the slag, fully dissolving the free calcium oxide and magnesium oxide in the slag. The treated slag is stable, facilitating its subsequent utilization. Granulation of the slag allows for more thorough separation of the slag and iron, facilitating magnetic separation.
[0016] By selecting a slag suffocation device, cover, traction bracket, traction device, cover bracket, spray device, and dust removal device, various types of steel slag can be treated by spraying water and suffocating slag. The generated steam and dust are absorbed and discharged through the dust removal system. This improves the level of automation, reduces the safety issues caused by direct human involvement, increases the processing capacity of steel slag, and ensures environmental protection.
