The annular pipe 11 is located above the splash guard 12. Multiple air jets 13 are evenly fixedly connected to the lower side of the annular pipe 11. Multiple drainage holes 14 are evenly opened at the bottom of the rack 6.

[0025] In the above embodiment, during use, the quarter-tooth ring is placed on the carrier 6, and the carrier 6 is moved by the drive mechanism 5 to the quenching tank 2 for quenching. After quenching, the quarter-tooth ring is moved to the splash guard 12 by the drive mechanism 5. The hot air blower 8 is started, and the hot air blower 8 takes in air through the air inlet pipe 9 and then delivers the hot air to the annular pipe 11 through the air guide pipe 10. The hot air in the annular pipe 11 is blown onto the quarter-tooth ring on the carrier 6 through multiple jet nozzles 13, so that the quenching and tempering liquid on the quarter-tooth ring can be quickly removed from the quarter-tooth ring. Then the drive mechanism 5 moves the quarter-tooth ring to the tempering furnace 3 for tempering treatment, so as to prevent the residual quenching and tempering liquid on the quarter-tooth ring from affecting the tempering effect and effectively improve the heat treatment effect of the quarter-tooth ring.

[0033] Working principle: During use, the quarter-tooth ring is placed on the carrier 6, and the carrier 6 is moved by the drive mechanism 5 to the quenching tank 2 for quenching. After quenching, the quarter-tooth ring is moved to the splash guard 12 by the drive mechanism 5. The hot air fan 8 is started, and the hot air fan 8 takes in air through the air inlet pipe 9 and then delivers the hot air to the annular pipe 11 through the air guide pipe 10. The hot air in the annular pipe 11 is blown onto the quarter-tooth ring on the carrier 6 through multiple jet nozzles 13, so that the quenching and tempering liquid on the quarter-tooth ring can be quickly removed from the quarter-tooth ring. Then the drive mechanism 5 moves the quarter-tooth ring to the tempering furnace 3 for tempering treatment, which can prevent the residual quenching and tempering liquid on the quarter-tooth ring from affecting the tempering effect and effectively improve the heat treatment effect of the quarter-tooth ring.
