[0026] Specifically, in the traditional large vertical cooler, the cross section of the cooling box is generally a rectangular structure, and it is difficult to uniformly distribute the feed in the entire cross section during the distributing process.
[0027] The uniform distributing system designed in Embodiment 1 of the present application is provided with a plurality of (two or more can be arranged according to the size of the cooler) data acquisition cameras (i.e. the shooting units 31, which can be laser radar, three-dimensional laser scanner and the like) arranged on the cooler top cover 12, the working principle of which is to use the data acquisition cameras to take high-frequency real-time pictures (material accumulation image acquisition) of the material (feed) in the cooling box 11, then transmit the photographed image files to the graphic acquisition module 32 for data processing signal conversion, and then perform modeling by the data processing host 33 to generate a real-time cloud picture, the real-time cloud Figure 1The aspect can allow the user to view the material distribution inside the cooling box 11 online and understand the internal material distribution.

At the same time, the servo motor roller 252 can match different rotating speeds according to the coordinate information, so as to realize the adjustment of the material throwing distance. Combining the precise angle adjustment of the material distribution assembly 25 and the adjustment of the material throwing distance of the servo motor roller 252, the material can be placed at a fixed point in the cooling box 11. The specific implementation process can be divided into three stages. The initial stage is the starting feeding stage, that is, the stage from when the material enters the cooling box 11 to when the material layer is not high enough. At this time, the servo motor roller 252 can be set to rotate at a uniform speed to uniformly distribute the material. At this time, the data acquisition camera 31 only plays an auxiliary monitoring role. When entering the second stage, that is, when the material has accumulated to a certain height and there is a clear height difference between the materials, the data acquisition and control system starts to operate as a whole. Through the cloud information feedback, combined with the direction adjustment of the material distribution assembly 25 and the speed change of the servo motor roller 252, the low material layer part is realized. The fixed point feeding is supplemented. The third stage is when the internal material is basically uniform, and then the uniform material distribution system returns to the first stage for material distribution, so as to form a closed loop control.
[0028] The above is only used to explain the application, and does not limit the application. Any obvious changes or changes derived from the technical solutions of the application are still within the protection scope of the application.
