Then, the first fixing bolt 254 on the second box body 25 is loosened, the second box body 25 is completely removed, and then the fixing rod 27 is removed to remove the storage box.

[0051] Working principle: First, metal powder is placed in a storage box, which is provided with multiple leakage holes. The diameter of the leakage holes is smaller than that of the metal powder to prevent the metal powder from leaking out and facilitate oil immersion. Then, the storage box is placed in the inner box 251 of the second box body 25 and fixed with a fixing rod 27. Then, the second box body 25 is placed in the first box body 24 and fixed with a second fixing bolt 261. After fixing, the pool body cover 28 is closed to seal the processing pool 23. Then, an oil pump 31 is started to input oil into the processing pool 23 through the input pipe 311.

The motor 21 drives the first bevel gear 211 to rotate, which in turn drives the second bevel gear 221 to rotate, and then drives the entire treatment assembly 2 to rotate, and deoiling is performed by the action of centrifugal force. After deoiling is completed, the tank body cover 28 is opened, and the sealing cover 26 is inserted into the compartment 252 of the second box body 25, and sealed by the action of the sealing rubber sleeve 6. The sealing cover 26 and the second box body 25 are fixed with the second fixing bolt 261, and then the first fixing bolt 254 on the second box body 25 is loosened, the second box body 25 is taken out as a whole, and then the finished product is taken out of the storage box to complete the oil immersion deoiling.
