In the process of feed production, when the finished material falls into the finished product warehouse, due to the different particle size and specific gravity of the feed, under the action of gravity flow and vacuum phenomenon, the finished product classification and packaging are different, affecting the quality of the finished product.  

To solve the feed production link caused by the feed classification problem. The company through repeated experimental design and development of "with anti-grading buffer structure of feed finished product warehouse" and related patent technology, to achieve high quality mass production.  The application of this technology can achieve the ideal uniformity, the variation coefficient of finished materials from the mixer into the finished product warehouse is not higher than 3%, reduce the waste of raw materials, energy and manpower, reduce the annual production cost of more than 3.3 million yuan, economic and social benefits are significant.  

Main design idea and characteristics: 1, in the warehouse is equipped with a nozzle, 2, between the nozzle and the silo wall is equipped with a fixed bracket, 3, in the diversion pipe wall per meter is equipped with a buffer layer on the wing, the number of each layer cushion wing for three, four, diversion pipe and each corresponding buffer wing equipped with material overflow mouth, 5, the sidewalls of the warehouse has return duct; the included Angle between the buffer wing and the diversion tube is 120-125 degrees.

Innovation point of this project is that the body is equipped with a vertical guide tube, the material overflow mouth wings, buffer, return air duct, such as internal structure, and according to certain fixed position and Angle of the connection, when materials into finished products warehouse, by airflow and buffer device such as wing changes because of the proportion of natural sedimentation condition, improve the product uniformity, avoid secondary mixing. At the same time, supporting other technologies can play a more effective role in improving product quality and reducing production costs. The difficulty of design and experiment lies in the selection of design parameters, accurate sampling and accurate experimental analysis.
