The height of the concave plate 4222 is higher than that of the slope surface 221, so that the aluminum slag is extruded through the slope surface 221, and the discharging operation is completed.
Preferably, along the rotation direction of second pivot 421, lateral wall opening 31 is the slope upwards to set up, and the lateral wall opening 31 of slope setting can increase second stirring leaf 422 rotation in-process and the "contact" time of lateral wall opening, promotes the aluminium sediment volume of once beating into in lateral wall opening 31 promptly to the slagging-off efficiency has been promoted.
Example 5:
as shown in fig. 1 to 5, for the above embodiment, the present embodiment optimizes the aluminum liquid recovery structure.
This waste heat utilization type slag clearance is smelted and is in the device flue gas collecting pipe 81 give vent to anger the end and point to and be close to slope 221, and flue gas collecting pipe 81 give vent to anger the directional first pivot 411 of end, sweep the high temperature flue gas directly to slope 221, can heat the aluminium liquid that carries in the aluminium sediment, promote the backward flow recovery volume of aluminium liquid, the flue gas that blows off is in slagging-off stove 3 with the trend (because the effect of dust collecting cover 33 makes the top of slagging-off stove 3 be in relative negative pressure state), need not to reuse the natural gas and heats, the utilization ratio of energy has been promoted.
Example 6:
as shown in fig. 1 to 4, the present embodiment optimizes the filtering structure for the above-described embodiment.
In the waste heat utilization type slag cleaning and smelting device, a grate plate 32 is arranged at the communication part of the third discharging channel 23 and the slag removing furnace 3. The grate plate 32 is arranged, so that the influence of the pressure formed by the rotational flow of the aluminum slag on the slag removal effect caused by the fact that the aluminum slag enters the third discharging channel 23 is reduced.
Preferably, the discharge amount of the slagging furnace 3 can be adjusted by setting the throughput of the grid plate 32.
Example 7:
as shown in fig. 1 to 5, the present embodiment optimizes the filtering structure for the above-described embodiment.
In the waste heat utilization type slag cleaning and smelting device, the position of the communication part of the first discharging channel 21 and the slag removing furnace 3 is lower than the height of the side wall opening 31. As shown in fig. 5, the communication part of the first discharging channel 21 and the slagging furnace 3, i.e. the feeding end of the slagging furnace 3 is positioned below the liquid level of the aluminum solution, so that the aluminum solution in the first discharging channel 21 has less chance of contacting with oxygen in the air, and the stability of the surface of the molten solution in the slagging furnace 3 can be improved; and can reduce, when feeding in raw material from the top, water aluminium solution on the dross, and cause the increase of loss, promoted the result of use of this device.
