Description

Technical Field

[0001] The present application relates to the technical field of hot stuffing equipment, and in particular to a hot stuffing slag water supply and drainage quick connection device. Background Art

[0002] Steel slag is a waste product produced by converter steelmaking. Tank hot stuffing is a process for treating steel slag. Bottom water supply and drainage is the process of supplying water to the hot stuffing tank from the bottom and draining the water after the hot stuffing is completed.

[0003] The reverse immersion method is a conventional method for adding water to and draining water from a hot stuffy tank. A water supply and drainage port is installed at the bottom of the hot stuffy tank, and a water supply and drainage pipe is connected to the port to supply water into the hot stuffy tank from the bottom and drain the water from the hot stuffy tank after the hot stuffing is completed. Existing hot stuffy tanks include an inner tank and an outer tank. The inner tank is installed inside the outer tank. The inner tank is filled with steel slag and then placed inside the outer tank. A lid is then installed. A rubber hose is manually placed over the water inlet pipe, the water inlet valve is opened, and water is pumped between the outer and inner tanks through the water inlet pipe. The water in the outer tank then overflows into the inner tank until it overflows the steel slag in the inner tank. The water in the water inlet valve is then closed, and the slag-stifling process begins for three hours. After the slag-stifling is completed, the rubber hose is manually disconnected from the water inlet pipe, and the water is drained through the water inlet pipe. After the drainage is completed, the inner tank is lifted out and transported to the next process. The slag-stifling process repeats itself.

[0004] In the actual slag-suffocating process, the temperature of the slag is above 500°C, and the temperature is transferred to the rubber tube through water. There is a risk of burns when manually disconnecting the rubber tube from the water inlet pipe. Therefore, there is a defect that manual connection and disassembly at the connection between the water inlet pipe and the rubber tube is cumbersome and dangerous. Utility Model Content
