[0033] The front and rear ends of the processing tank 4 are fixedly provided with rotating shafts 3 located at the support plate 2. The two rotating shafts 3 rotate inside the corresponding support plates 2 respectively. Through the action of the rotating shafts 3, the processing tank 4 rotates along the rotating shafts 3.
