Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a cross-track sedimentation tank structure. Background Art

[0002] During the continuous casting tank treatment process, the continuous casting tank is stagnant for too long when it is loaded with converter slag on site. As a result, when the continuous casting tank arrives at the slag tank treatment site, the slag in the tank has solidified and cannot be poured directly into the slag pool. In order to enable the continuous casting tank to quickly cool the high-temperature slag and to allow the cooled and solidified slag to be smoothly separated from the continuous casting tank, a spraying slow cooling process is required, that is, a spray water pipe is used to continuously spray cooling water on the high-temperature slag in the continuous casting tank, and the copper slag is separated from the tank body by water quenching. Therefore, this slow cooling process requires a large amount of water.

[0003] At present, continuous casting tanks are transported by train. Since it is impossible to meet the conditions for hoisting a single continuous casting tank to the slag pool for water pumping alone, the continuous casting tank can only be docked at the end of the hot-spraying line train track for water pumping. Since there is no water collection pool at the end of the existing hot-spraying line train track, there are the following disadvantages: First, a large amount of water is required in the process of water pumping and stewing of the continuous casting tank, and the water after spraying is directly discharged through the sewer, which will cause a great waste of water resources; second, due to the high alkalinity of the slag, the carbonate of some slag enters the water in the form of suspended matter, which increases the total hardness and pH value of the water, resulting in serious excess of water quality. Direct discharge through the sewer will cause water pollution in the surrounding environment of the plant. Therefore, it is urgent to develop and design a sedimentation tank that collects stewing water across the train track. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cross-track sedimentation tank structure in view of the above-mentioned deficiencies in the prior art, thereby reducing water waste in the continuous casting tank spraying process and avoiding water pollution caused by slag stewing water to the environment around the factory area.
