[0014] like Figure 1-2As shown, a rotary tube bundle drying device with a built-in crushing unit includes a rotary tube bundle drying device shell 1. The rotary tube bundle drying device shell 1 is a rotating structure that drives the material inside to rotate and tumble. The material enters from the feed end of the rotary tube bundle drying device shell 1 and exits from the discharge end of the rotary tube bundle drying device shell 1. A motor reducer drive device 2 is provided at the bottom of the rotary tube bundle drying device shell 1 to drive the rotation of the rotary tube bundle drying device shell 1. The motor reducer drive device 2 includes a motor reducer and a drive gear driven by a motor. A ring gear that cooperates with the drive gear is provided on the outside of the rotary tube bundle drying device shell 1. The motor reducer drives the rotating tube bundle drying equipment housing 1 to rotate via a ring gear and a drive gear. Roller supports 3 are installed on both sides of the motor reducer drive unit 2, supporting the rotating tube bundle drying equipment housing 1. Rollers are installed at the top of the roller supports 3, contacting the rotating tube bundle drying equipment housing 1. The rollers rotate along with the rotating tube bundle drying equipment housing 1 during rotation. An air inlet / feeding fixed end 4 is installed at the feed end of the rotating tube bundle drying equipment housing 1. The air inlet / feeding fixed end 4 is a stationary component, and the rotating tube bundle drying equipment housing 1 is rotatably mounted to the air inlet / feeding fixed end 4. The end of the air inlet / feeding fixed end 4 is... A feeding screw 5 feeds the material to be dried into the housing 1 of the rotary tube bundle dryer. The discharge end of the housing 1 is equipped with a discharge venting fixed end 6, which is a stationary component. The housing 1 and the discharge venting fixed end 6 are rotatably mounted. The discharge venting fixed end 6 has a discharge port 7, from which the dried material is discharged. Sealing devices 8 are installed at the installation points of the rotary tube bundle dryer housing 1, the venting fixed end, and the discharge venting fixed end 6 to prevent material overflow. Lifting plates 9 are installed on the inner wall of the rotary tube bundle dryer housing 1. The rotating housing 1 pushes and throws the material inside the rotating tube bundle dryer housing 1 forward and upward through the lifting plate 9, so that the material flows from the feed end of the rotating tube bundle dryer housing 1 to the discharge end of the rotating tube bundle dryer housing 1. The rotating tube bundle dryer housing 1 is equipped with a heating tube bundle 10. When the material comes into contact with the heating tube bundle 10, the water evaporates. The discharge fixing device is equipped with an air inlet and water outlet rotary joint 11 connected to the heating tube bundle 10. Hot air enters the heating tube bundle 10 from the air inlet end of the air inlet and water outlet rotary joint 11 to provide heat, and the steam generated inside the rotating tube bundle dryer housing 1 is discharged from the water outlet end of the air inlet and water outlet rotary joint 11.

[0015] The rotary tube bundle dryer has a pulverizing mechanism 12 inside, which includes a rotating shaft 12-1 and pulverizing claws 12-2. The rotating shaft 12-1 is rotatably mounted to the rotary tube bundle dryer housing 1. A moving ring bevel gear 13 is provided on the outside of the pulverizing mechanism 12 to drive its rotation. The rotating shaft 12-1 passes through the rotary tube bundle dryer housing 1 and is fixedly connected to the middle of the moving ring bevel gear 13.

The rotating shaft 12-1 and the moving ring bevel gear 13 at the end of the rotating shaft 12-1 rotate around the central axis of the rotating tube bundle dryer housing 1. The stationary ring bevel gear 14 is a stationary component. During the rotation of the moving ring bevel gear 13 around the central axis of the rotating tube bundle dryer housing 1, it meshes with the stationary ring bevel gear 14 and rotates, thereby driving the crushing mechanism 12 to rotate and releasing rotational force to disperse the material. The crushing mechanism 12 is installed at the high viscosity and high moisture feed end.
