[0016] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] See also Figure 1-5The utility model provides a technical solution: a fixed-point rotating material distribution device of a vertical dryer, including a feed section housing 1 and a material distribution component. The inner circumferential direction of the feed section housing 1 is evenly divided into three material areas 2, each area is respectively provided with a material level switch 4, and the material level switch 4 is divided into an upper material level switch 41 and a lower material level switch 42. The upper material level switch 41 and the lower material level switch 42 are used to detect the material level of the material area 2, so as to facilitate timely replenishment. The material distribution component is arranged on the top of the feed section housing 1, and the material distribution component includes a slewing support 6, a support seat 7 and a chute 5, and the support seat 7 is fixed at the center of the upper end of the feed section shell 1, the slewing support 6 is installed on the support seat 7, the chute 5 is located inside the feed section shell 1, the upper end of the feed section shell 1 is fixedly connected to the lower end of the slewing support 6, a proximity switch 14 is provided in the circumferential direction of the slewing support 6, and a detection plate 15 is provided on the slewing support 6. The proximity switch 14 can detect the rotating position of the slewing support 6, and then determine which material area 2 the chute 5 is located in, so as to facilitate accurate fixed-point feeding of the corresponding material area 2, avoid frequent starting of the feeding device, and save energy consumption and running time of the feeding device.

[0018] There are three proximity switches 14, which correspond to the material level switches 4 one by one. The proximity switches 14 are mounted on the bracket 12 on the top surface of the feed section housing 1. When the material level switch 4 detects that a certain material area 2 is out of material, the proximity switch 14 in the corresponding area is activated to make the material distribution device pause in the area for a certain period of time, and to distribute the material to the area separately. After the fixed time is over, the proximity switch 14 is automatically closed, and the material distribution device is restarted to distribute the material evenly in the circumferential direction.

[0019] An air duct 3 is arranged in the feed section housing 1, and a material baffle plate 11 is arranged on the top of the air duct 3. The material baffle plate 11 plays a role in protecting the air duct 3, and the periphery of the air duct 3 is a material drying area.

The output shaft of the drive motor 10 is connected to a driving gear 8, and the driving gear 8 is meshed with an outer gear ring 13 on the outer circumference of the slewing support 6. The drive motor 10 drives the slewing support 6 to rotate through gear transmission, and the upper end of the slewing support 6 is connected to the feed port and the conveyor.

[0021] The proximity switch 14, the material level switch 4 and the drive motor 10 are controlled by the dryer control system.

[0022] Distribution principle: when two or more material areas 2 are short of material, start the vertical dryer feeding and conveying system and the device to replenish the dryer, and detect through the material level switch 4. When two or more material areas 2 are at a high material level, close the feeding system and the distribution device. The material is evenly distributed in the circumferential direction of the vertical dryer by the distribution device. There are certain differences in the working conditions of each area. After long-term operation, there will be large differences in the material level heights of each material area 2. According to the signal of the material level switch 4, when the same area is short of material for three consecutive times, start the proximity switch 14 of the corresponding area, and the drive motor 10 drives the slewing support 6 to make the chute 5 pause in this area for a certain period of time, and distribute the material to this area separately. After the fixed time ends, the proximity switch 14 is automatically closed, and the distribution device is restarted to distribute the material evenly in the circumferential direction. When two or more material areas 2 are at a high material level, stop running the feeding system and the distribution device.
