Description

Technical Field

[0001] The utility model relates to the technical field of brown sugar granule screening, in particular to an automatic classification device for screening and sorting brown sugar granules. Background Art

[0002] The process of dividing bulk materials into different particle sizes through one or several layers of screens is called screening. Screening machine is a vibrating screening machine that uses the relative movement between bulk materials and the screen surface to make some particles pass through the screen holes, and divides materials such as sand, gravel, and crushed stone into different levels according to particle size. The screening process of the screening machine is generally continuous. After the screened raw materials are fed to the screening machine (referred to as the screen), the materials smaller than the size of the screen holes pass through the screen holes, which are called undersize products; the materials larger than the size of the screen holes are continuously discharged from the screen surface, which are called oversize products. The screening machine uses the difference in size and quality of the materials, as well as the different sedimentation speeds of the liquid, so that the small materials and the larger materials sink to the bottom of the tank. The grading screen uses a spiral to push the materials upward, and then performs mechanized screening. The equipment can filter out the materials in the mill according to the level, and finally use the spiral blade to screw the larger materials into the mill feed port, and the filtered small materials overflow from the overflow pipe.

[0003] When screening brown sugar granules, most of the current screening and sorting automatic classification devices can only sort out qualified small and medium granules. However, there may be unqualified large granules in the raw materials to be sorted. If the large granules are sorted into the medium granules, the consumption of the medium granule brown sugar will be affected. Utility Model Content
