DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0021] Please refer to Figures 1 to 4, in the present utility model, a vacuum rake dryer includes two vertical frames 1. A tank body 2 is fixedly installed between the two vertical frames 1. A driving member 3 is installed on the left vertical frame 1, and the output part of the driving member 3 extends into the interior of the tank body 2. A diversion cavity 4 is formed inside the tank wall of the tank body 2. Connecting valves 5 are installed on both the left side and the bottom of the tank body 2. A rake rod 6 is rotatably connected inside the tank body 2. The left end of the rake rod 6 is connected and cooperated with the driving member 3. A communication groove 7 is formed inside the rake rod 6. The right end of the rake rod 6 extends to the right side of the tank body 2 and is rotatably connected to the vertical frame 1. The right end of the rake rod 6 penetrates to the right side of the vertical frame 1. A rotary joint 8 connected to the rake rod 6 is installed on the right side of the vertical frame 1. Two groups of hollow branch rods 9 are arranged on the outer side of the rake rod 6, and arc-shaped water spray heads 10 are installed at the ends of the branch rods 9.

[0022] In the present utility model, after injecting materials into the interior of the tank body 2, the tank body 2 is evacuated, then high-temperature steam is injected into the diversion cavity 4 for heating, and the driving member 3 is started to drive the rake rod 6 to rotate to stir the materials to achieve drying. After the drying is completed and the materials are discharged, at this time, the interior of the tank body 2 needs to be cleaned. At this time, only an external water pump needs to be connected through the rotary joint 8, then high-pressure water flow is injected into the communication groove 7, and then the inner wall of the tank body 2 is flushed through the branch rods 9 and the arc-shaped water spray heads 10 without opening. And when flushing, the driving member 3 is started at the same time to drive the rake rod 6 to rotate to achieve all-round and dead-angle-free cleaning. Thus, the device has the advantages of good cleaning effect, convenient operation and dead-angle-free cleaning, solving the problems in the prior art that the equipment structure is generally a closed structure, a cleaning hatch is reserved, and it needs to be flushed from the outside by personnel to clean the interior, with inconvenient operation and easy generation of dead angles and poor cleaning effect.
