DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with embodiments.

[0016] Embodiment 1, as Figures 1 to 3 As shown, the utility model is an oil sludge recovery and transmission device, including a conveyor 1, which is a closed conveying elevator. The feed port 13 of the conveyor 1 is connected to a spiral elevator, and the spiral elevator includes a lifting cylinder 2. A lifting spiral 17 is arranged in the lifting cylinder 2. A lifting motor 14 is fixed to the upper end of the lifting cylinder 2, and a mud inlet pipe 5 connected to the mud outlet of the kiln is fixed to the top of the lower end of the lifting cylinder 2. A mud outlet pipe 12 is fixed to the bottom of the upper end of the lifting cylinder 2, and a star-shaped discharge valve 11 is fixed to the lower end of the mud outlet pipe 12, and the bottom outlet of the star-shaped discharge valve 11 is connected to the feed port 13 of the conveyor 1.

[0017] During operation, the mud discharged from the kiln enters the lifting cylinder 2 of the spiral elevator from the mud inlet pipe 5, and then is lifted to the mud outlet pipe 12 by the lifting screw 17 for discharge, and then falls to the star-shaped discharge valve 11, and is discharged stably through the star-shaped discharge valve 11. Then the mud enters the conveyor 1 from the feed port 13 and is transported to the warehouse through the closed conveyor elevator.
