[0004] But there may be some technical problems in the use process, for example: after the device is completed, if the dried calcium carbide slag is poured out of the box, the cover needs to be opened, and the box needs to be inclined, so that the calcium carbide slag in the box falls out of the box under the action of gravity, which increases the labor intensity of the workers, and the workers cannot pour the calcium carbide slag out of the box, and the device can only dry the calcium carbide slag, and the function is single. Utility model content

[0005] The utility model provides a kind of calcium carbide slag filtering and drying equipment, which can not only facilitate workers to take out the dried calcium carbide slag from the box, reduce the labor intensity of workers, but also make the device have filtering and drying functions simultaneously, increase the diversity of device functions.

[0006] The utility model discloses a filter drying equipment for carbide slag, which comprises a box body and a smoke inlet pipe installed on the right side of the box body.

[0007] In use, the filter device is used to convey the filtered carbide slag into the box body. Then, the driving mechanism is started to drive the hollow shaft to rotate on the sealing bearing between the box body and the transition sleeve. The rotation of the hollow shaft drives the spiral blade to rotate in the box body, thereby driving the carbide slag to move towards the discharge port in the box body. At this time, the discharge valve is closed, so the carbide slag cannot be discharged from the box body through the first discharge pipe. The high-temperature flue gas is introduced into the smoke inlet pipe, and then passes through the transition sleeve and enters the hollow shaft. The high-temperature flue gas is discharged from the through holes in the spiral blade, so that the high-temperature flue gas is discharged into the carbide slag. With the rotation of the spiral blade, the discharge angle of the high-temperature flue gas is continuously adjusted, thereby improving the drying effect of the carbide slag and accelerating the drying rate. When the carbide slag in the box body is dried, the discharge valve is opened, so that the carbide slag in the box body is discharged from the box body through the first discharge pipe of the discharge port under the drive of the spiral blade.
