A water pump 13 is fixedly installed, and a water outlet pipe 15 is fixedly installed at the output port of the water pump 13. A water storage chamber 18 is opened on the inner wall of the guide pipe 21. A motor 2 14 is fixedly installed on the outer wall of the guide pipe 21. A gear 2 19 is fixedly installed on the output shaft of the motor 2 14. A gear 2 19 is fixedly installed on the outer wall of the material transfer paddle 6. A gear ring 20 is fixedly sleeved on the outer wall of the material transfer paddle 6. A return pipe 1 16 and a return pipe 2 17 are fixedly installed on the top of the water tank 3 respectively. In the above structure, gear 2 19 is adjacent to the gear ring 20, and gear 2 19 is meshed with the gear ring 20. By starting the motor 2 14, the motor 2 14 drives the gear 2 19 to rotate, and the gear 2 19 drives the gear ring 20 to rotate by meshing with the gear ring 20, and the gear ring 20 drives the material transfer paddle 6 to rotate.

[0023] In a preferred embodiment, the outer wall of the crushing barrel 5 is provided with an annular tooth, and the height of the annular tooth is the same as the height of the gear 8. The annular tooth on the outer wall of the crushing barrel 5 is meshed with the outer wall of the gear 8. In the above structure, by starting the motor 7, the motor 7 drives the gear 8 to rotate, and the gear 8 drives the crushing barrel 5 to rotate by meshing with the annular tooth on the outer wall of the crushing barrel 5, so that the crushing paddle 11 on the inner wall of the crushing barrel 5 rotates.

[0024] In a preferred embodiment, the air storage box 10 is hollow, and the output port of the air outlet 12 extends to the interior of the air storage box 10. In the above structure, cold air is emitted by the air cooler 9, blown into the interior of the air storage box 10, and discharged through the air outlet 12 to cool the slag located between the crushing barrel 5 and the air storage box 10.

[0025] In a preferred embodiment, there are several crushing paddles 11, and the several crushing paddles 11 are arranged in a circular array on the inner wall of the crushing barrel 5. In the above structure, the crushing paddles 11 rotate so that when the slag falls between the crushing barrel 5 and the air storage box 10, the crushing paddles 11 crush the slag.

[0026] In a preferred embodiment, the outer wall of the water outlet pipe 15 is provided with two pipes, and the two pipes on the outer wall of the water outlet pipe 15 are the same as the water outlet pipe 15. The two pipes on the outer wall of the water outlet pipe 15 are respectively connected to the inner wall of the transfer paddle 6 and the inner wall of the water storage chamber 18. In the above structure, the coolant on the inner wall of the water tank 3 is extracted by the water pump 13 and discharged into the interior of the water outlet pipe 15. The coolant moves along the inner wall of the water outlet pipe 15. When the coolant reaches the two pipes on the outer wall of the water outlet pipe 15, the coolant moves into the two pipes.

[0027] In a preferred embodiment, the interior of the rotating shaft of the transfer paddle 6 is hollow, and the two ends of the transfer paddle 6 are respectively connected to the return pipe 17 and the outlet pipe 15. In the above structure, the coolant enters the interior of the transfer paddle 6 through the outlet pipe 15, reaches the interior of the return pipe 17 through the transfer paddle 6, and takes away the heat inside the transfer paddle 6, and finally enters the interior of the water tank 3 through the return pipe 17 to complete the reflux.

[0028] Working principle: when using this equipment, the feed port at the top of the guide pipe 21 is installed below the slag outlet of the rotary kiln. At this time, the slag enters the interior of the guide pipe 21 through the feed port at the top of the guide pipe 21. At this time, the water pump 13 and the motor 14 are started. The water pump 13 extracts the coolant from the inner wall of the water tank 3 and discharges it into the interior of the outlet pipe 15. The coolant moves along the inner wall of the outlet pipe 15. When the coolant reaches the two pipes on the outer wall of the outlet pipe 15, the coolant flows into the two pipes. The cooling liquid moves to the inner wall of the water storage chamber 18 and the material transfer paddle 6. At this time, the motor 2 14 is started, so that the motor 2 14 drives the gear 2 19 to rotate. The gear 2 19 meshes with the gear ring 20 to drive the gear ring 20 to rotate. The gear ring 20 drives the material transfer paddle 6 to rotate, and drives the slag to move. When the slag falls on the inner wall of the guide pipe 21, the heat of the slag itself will be transferred to the inside of the guide pipe 21 and the material transfer paddle 6. At this time, since the cooling liquid reaches the water outlet pipe 15 and the water storage chamber, the cooling liquid will be cooled by the cooling liquid. The heat is taken away from the interior of the water storage chamber 18, and the coolant in the water storage chamber 18 eventually flows back to the interior of the water tank 3 through the return pipe 16, and the coolant in the material transfer paddle 6 flows back to the interior of the water tank 3 through the return pipe 2 17, so as to initially dissipate the heat of the slag. When the slag reaches the interior of the crushing box 2 through the guide pipe 21, the air cooler 9 and the motor 7 are started at this time, and the air cooler 9 blows cold air into the interior of the air storage box 10, and the cold air is driven into the space between the crushing barrel 5 and the air storage box 10 through the air outlet 12. When the slag passes through the top of the air storage box 10 and reaches between the crushing barrel 5 and the air storage box 10, due to the starting of the motor 7, the gear 8 is driven to rotate, and the gear 8 drives the crushing barrel 5 to rotate, so that the crushing paddle 11 inside the crushing barrel 5 rotates, and the slag is crushed. While the slag is crushed, the slag is cooled by the cold air blown out from the air outlet 12 and falls downward to the interior of the storage box 1, and finally falls into the interior of the collection box 4. The interior of the collection box 4 can be cleaned regularly.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
