Description

TECHNICAL FIELD

[0001] The utility model relates to a cane leaf mud and sand separation equipment and relates to the technical field of cane sugar manufacturing equipment. BACKGROUND

[0002] In recent years, raw material supply of cane sugar enterprises accelerates the transformation to mechanized harvesting, aiming to improve labor productivity and reduce raw material cost. However, the machine-harvested cane raw materials are often mixed with a large amount of sundries such as soil, sand, and cane leaves. The impurity content of most cane raw materials is as high as 10%-15%, which seriously affects the output and sugar quality of sugar mills, and increases equipment wear and maintenance cost. The existing impurity removal equipment mostly adopts a grid or rotating tooth roller structure. When the cane raw materials move in a straight line, the impurity removal rate is difficult to reach 70% due to the restriction of cane layer thickness and yield, which cannot meet the production needs of sugar mills. Moreover, the existing impurity removal equipment of sugar mills can only separate soil and sand from cane raw materials together with cane leaves in a short time, and cannot further effectively separate soil and sand from cane leaves. The separated sundries are still relatively high. With the promotion of comprehensive utilization of cane leaves as feed, fertilizer, and fuel, effective separation and centralized collection of cane leaves have become a new demand for cane sugar enterprises to reduce cost and increase efficiency and high-quality development.
