Description

Technical Field

[0001] The utility model relates to the field of immersion cooling drums, in particular to an immersion cooling drum. Background Art

[0002] In the process of preparing sulfuric acid from ore, the slag ash discharged from the bottom of the boiling furnace and the slag ash separated by the cyclone separator and dust collector cannot be discharged directly due to the high temperature of up to 650°C, so the slag ash needs to be cooled before discharge. At present, cooling drums are mainly used to cool the ash and recover heat. The cooling water used to cool the slag ash by the immersion cooling drum cannot have too many impurities, otherwise it will clog the pipeline. The existing method is to send the used cooling water to an external filter device for filtration, but the pipeline between the immersion cooling drum and the filter device will still be clogged, resulting in inconvenience in maintenance and increased maintenance costs.

[0016] In the drawings, the same reference numerals all refer to the same components.

[0017] like Figure 1 As shown, the utility model provides an immersion cooling drum, comprising a feed drum 1, a cooling drum 2 and a discharge drum 3, the feed drum 1, the cooling drum 2 and the discharge drum 3 are connected in sequence, the outer side of the cooling drum 2 is covered with a water tank 7, the bottom end of the water tank 7 is provided with a filter assembly 4, the filter assembly 4 is connected with the water tank 7, and the top of the water tank 7 is provided with a spray assembly 5; a heat exchanger 8 is provided on one side of the water tank 7, and a pipeline 6 is provided between the heat exchanger 8 and the filter assembly 4 and the spray assembly 5.

[0018] In this embodiment, the hot slag enters the cooling cylinder 2 through the feed cylinder 1 and accumulates to a certain height around the feed cylinder 1. When the gravity generated by it is balanced with the gravity of the slag flow in the tube, the slag flow in the feed cylinder 1 is blocked. When the feed cylinder 1, the cooling cylinder 2 and the discharge cylinder 3 rotate to push the slag to the end of the discharge cylinder 3, the height of the slag pile around the feed cylinder 1 decreases accordingly, breaking the gravity balance of the slag inside and outside the feed cylinder 1, and the slag flow in the feed cylinder 1 continues to move, thereby achieving the purpose of slag feeding and discharging. When the slag passes through the cooling cylinder 2, the spray assembly 5 in the water tank 7 cools the cooling cylinder 2, thereby taking away the temperature of the slag in the cooling cylinder 2, achieving the purpose of cooling the slag; the heat exchanger 8 of the prior art is used in conjunction with the pipeline 6 to exchange heat with the filtered cooling water, so that the cooling water reaches the required temperature for cooling, and the cooling water of the cooling cylinder 2 is filtered by the filter assembly 4 and then cooled again.
