The track member 22 is used for allowing the processed workpiece to move on the rotating part 21. The rotating part 21 of the rotating table 2 is disc-shaped as a whole, and its center is the rotation center. The rotating part 21 is arranged on the ground. After the workpiece enters the cleaning chamber 1, it can be parked on the rotating part 21. During the cleaning process, the rotating part 21 will drive the workpiece to rotate together, so that the cleaning water can be evenly and comprehensively sprayed to the outside of the workpiece, thereby achieving a more efficient cleaning operation.

[0042] The spray pipe 3 is fixed in the cleaning chamber 1 and extends to the top of the rotating table 2 to spray and clean the processed workpieces on the rotating table 2. The pipeline of the spray pipe 3 is fixed in the cleaning chamber 1. A plurality of nozzles are arranged on the spray pipe 3. The nozzles can be directly arranged on the top of the inner wall of the cleaning chamber 1 to spray and clean the workpieces from top to bottom. For some special irregular workpieces, the nozzles can be set to a movable or inclined state to reduce cleaning dead angles.

[0043] The transfer mechanism 4 is arranged on the ground and is located outside the door of the cleaning chamber 1. The transfer mechanism 4 includes a track assembly 41, and the track assembly 41 is used to dock with the track member 22 so that the processed workpiece enters the cleaning chamber 1 through the transfer mechanism 4. The transfer mechanism 4 can dock with the track member 22 of the rotating table 2 to allow the workpiece staying on the transfer mechanism 4 to enter the cleaning chamber 1. In this embodiment, the workpiece removed from the thermal cleaning furnace is the processed workpiece, that is, the workpiece after processing in the thermal cleaning furnace needs to be transferred to the transfer mechanism 4, and docked through the transfer mechanism 4 to enter the cleaning chamber 1 for cleaning operations.

[0044] In this embodiment, a water tank 5 and a delivery pump 6 are also included. The water tank 5 is fixed outside the cleaning chamber 1 to store cleaning water.
