Description

Technical Field

[0001] The utility model relates to an automatic opening and closing mud grabbing device for cleaning sludge in a steel slag sedimentation tank, belonging to the technical field of converter steel slag tailing cleaning equipment. Background Art

[0002] In the steelmaking plant slag production process, the slag needs to be pulverized by hot stewing. The hot stewing process of the slag is nearly 1000°C high temperature slag, which is cooled by cold water for 30 hours. In this process, a large amount of slag fine sand will be generated and flow into the sedimentation tank through the cooling water channel. A large amount of sludge is formed in the sedimentation tank, which is cleaned and discharged by a special grab to meet the water circulation requirements for continuous treatment of slag.

[0003] At present, there are two ways to deal with sludge in sedimentation tanks: one is to use a high-power suction sludge pump to suck it out, and the external discharge requires a large area to dry it before transportation and treatment; the other is to use an extended arm excavator to directly dig it up and discharge it with a mud tank. The disadvantage of the first method is that the return water temperature of the sedimentation tank is high, which greatly exceeds the designed high-temperature mud pump's tolerance range. The mud pump is frequently damaged. In addition, the suction pump port is fixed and the sludge suction range is small. It is difficult to meet the requirements of large-scale sludge cleaning in the sedimentation tank. Moreover, the pumped sludge needs a large area for a long time to dry, and the subsequent transportation causes secondary dust pollution to the environment. The second method cannot meet the needs of grabbing mud in the entire area due to the large area of ​​the sedimentation tank, coupled with environmental factors such as buildings around the sedimentation tank. The excavator will leak mud during the grabbing process, and the large turning radius will cause a large risk of personal accidents. Utility Model Content
