Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figure 1-2As shown, a rotary tube bundle dryer with a fan-type discharge device 12 includes a rotary tube bundle dryer body 1. The rotary tube bundle dryer body 1 has a rotating structure, which drives the material inside to rotate and tumble and evaporate with hot water. The material enters from the feed end of the rotary tube bundle dryer body 1 and exits from the discharge end of the rotary tube bundle dryer body 1. A motor reducer drive device 2 is provided at the bottom of the rotary tube bundle dryer body 1 to drive the rotation of the rotary tube bundle dryer body 1. The motor reducer drive device 2 includes a motor reducer and a drive gear driven by the motor. The exterior of the rotary tube bundle dryer body 1 is provided with... A ring gear, which meshes with the drive gear, drives the rotating tube bundle dryer body 1 to rotate via the starting motor reducer and the ring gear. Roller supports 3 are located on both sides of the motor reducer drive unit 2, supporting the rotating tube bundle dryer body 1. Rollers are located at the top of the roller supports 3, contacting the rotating tube bundle dryer body 1. These rollers rotate along with the rotating tube bundle dryer body 1 during rotation. An air inlet and feeding fixing device 4 is located at the feed end of the rotating tube bundle dryer body 1. This air inlet and feeding fixing device 4 is a stationary component, and the rotating tube bundle dryer body 1 is connected to the air inlet... The feeding fixing device 4 is rotatably installed, and a feeding screw is provided at the end of the feeding fixing device 4. The material to be dried is fed into the rotary tube bundle dryer body 1 through the feeding screw. A discharge fixing device 6 is provided at the discharge end of the rotary tube bundle dryer body 1. The discharge fixing device 6 is a stationary part. The rotary tube bundle dryer body 1 and the discharge fixing device 6 are rotatably installed. A discharge port 7 is provided on the discharge fixing device 6. The dried material is discharged from the discharge port 7. Sealing is provided at the installation points of the rotary tube bundle dryer body 1 and the feeding fixing device 4 and the discharge fixing device 6, respectively. Device 8 prevents material overflow. A lifting plate 9 is installed on the inner wall of the rotary tube bundle dryer body 1. The rotary tube bundle dryer body 1 rotates and the lifting plate 9 pushes the material in the rotary tube bundle dryer body 1 forward and throws it upward, so that the material flows from the feed end of the rotary tube bundle dryer body 1 to the discharge end of the rotary tube bundle dryer body 1. A heating tube bundle 10 is installed in the rotary tube bundle dryer body 1. The material comes into contact with the heating tube bundle 10 and is heated to evaporate the moisture. A steam pipeline 11 is installed on the discharge and steam fixing device 6. The steam generated in the rotary tube bundle dryer body 1 is discharged from the steam pipeline 11.

[0015] The rotary tube bundle dryer body 1 is equipped with a fan-type discharge device 12 at the discharge end. The fan-type discharge device 12 is located inside the discharge and air-out fixing device 6. The fan-type discharge device 12 includes an annular mounting plate 12-1 fixedly installed with the rotary tube bundle dryer body 1 and multiple buckets 12-2 installed in a reverse fan-type manner on the outside of the annular mounting plate 12-1. The annular mounting plate 12-1 rotates integrally with the rotary tube bundle dryer body 1. The dried material flows into the buckets 12-2 as it flows towards the discharge end. The buckets 12-2 rotate with the rotary tube bundle dryer under the drive of the annular mounting plate 12-1. A side discharge collection hopper 13 is provided on the lower outer side of the discharge and air-out fixing device 6. The material in the buckets 12-2 that move to the side discharge collection hopper 13 flows into the side discharge collection hopper 13 to complete the discharge of the rotary tube bundle dryer.

[0016] In one possible implementation, a discharge plate 12-21 is provided on one side of the bucket 12-2. When the bucket 12-2 rotates to the angle where the side discharge collection hopper 13 is located, the angle of the discharge plate 12-21 of the bucket 12-2 is greater than the material repose angle, and the material is discharged in the direction of the side discharge collection hopper 13 according to the guide.

[0017] Multiple buckets 12-2 are provided and are equidistantly distributed on the outside of the annular mounting plate 12-1. Multiple buckets 12-2 continuously discharge materials into the discharge collection bucket.

[0018] The bottom of the discharge and venting fixing device 6 is set as an arc surface, and the outer edge of the bucket 12-2 matches the arc surface. The arc surface can prevent excessive material from entering and accumulating between the bottom of the bucket 12-2 and the discharge and venting fixing device 6 after the material discharge is completed.

[0019] Driven by a motor and reducer drive device 2, the rotary tube bundle dryer body 1 rotates. Material enters the equipment via a feeding screw, is then pushed forward and thrown upward by the lifting plate 9, directly contacting the heating tube bundle 10 for heating and heat exchange. Moisture evaporates and mixes with dry air, discharging into the steam pipeline 11 of the discharge and gas outlet fixing device 6. Material accumulates at the discharge end of the rotary tube bundle dryer body 1. Once it reaches a certain height, it is collected by the bucket 12-2 on the annular mounting plate 12-1, which rotates integrally with the dryer body 1, and rotates clockwise. When the bucket 12-2 rotates to the angle of the side discharge collection hopper 13, the angle of the discharge plate 12-21 of the bucket 12-2 is greater than the material's angle of repose, and the material is discharged towards the side discharge collection hopper 13 according to the guide. In this invention, there is no accumulation inside the rotary tube bundle dryer, which reduces the installation height and optimizes daily maintenance efficiency.
