Heat-insulation slag-filtering groove

Abstract

The invention relates to a heat-insulation slag-filtering groove which comprises a groove body. One outer side wall of the groove body is provided with a water receiving pipe, and one end of the water receiving pipe stretches into the groove body. The side, close to the water receiving pipe, inside the groove body is provided with a flow changing device used for changing the flow direction of molten water. The end, close to the water receiving pipe, of the flow changing device is provided with an arc groove. The side wall, away from the water receiving pipe, of the groove body is provided with a water discharging mouth. The periphery of the groove body is provided with a heat-insulation layer which surrounds the outer wall of the groove body, and a vacuum structure is formed between the heat-insulation layer and the groove body. Compared with the prior art, by means of the heat-insulation slag-filtering groove, smelting molten water is subjected to slag-filtering, waste is avoided, the molten-water slag-removing efficiency is improved, and the operation of continuous-water-injection with an unsteady flow is met; and the vacuum structure is formed between the heat-insulation layer and the groove body, the heat-insulation layer is a vacuum heat-insulation plate, operating staff approach the groove body conveniently to observe the molten water in the groove body, and the state of the molten water is conveniently understood by operating staff.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a heat-insulated filter residue tank. Background technique [0002] Most of the technologies use skimmers to remove the scum on the molten water. The skimmers have the disadvantages of troublesome operation, and often bring good water out, resulting in waste. Another is to install it on the molten water transfer device. The filter plate has the disadvantages that it is difficult to control the scum and the scum is easy to mix; moreover, in the process of introducing molten water in the prior art, the amount of molten water is uneven, which often causes the molten water in the filter slag tank to overflow, and the scum cannot be removed cleanly. Furthermore, molten water produces a large amount of harmful gas, which must be removed. Contents of the invention [0003] The purpose of the present invention is to provide a heat-insulated filter slag tank. The technical problems to...

Problems solved by technology

[0003] The purpose of the present invention is to provide a heat-insulated filter slag tank. The technical problems to be solved are: the good water is often taken out, resulting in waste; the amount of molten water is uneven, which often causes the molten water in the filter slag tank to overflow, and the scum can not be removed. Clean, molten water produces a lot of harmful gases, it is necessary to remove
