谷物精选分离器的循环风系统
摘要：
本发明涉及一种谷物精选分离器的循环风系统，属于谷物的清理、分级技术领域，包括支架，支架上安装有工作室和风机，风机位于工作室右侧，其特征在于：风机出口通过风道与工作室相通，工作室左侧相通连接有沉降室，沉降室通过回风管道与风机入口连接相通。通过本发明，其结构简单，形成一个风机→风道→工作室→沉降室→回风管道→风机的循环风系统，从而省去了复杂的除尘设备，降低了生产成本，有效地防止了粉尘污染；在排气装置的作用下进一步避免了空气中产生的粉尘污染。
摘要（英）：

The invention relates to a circulating air system of a grain fine-selecting separator, and belongs to the technical field of cleaning and grading of grain. The system comprises a support, a work chamber and a fan are installed on the support, and the fan is located on the right side of the work chamber. The system is characterized in that an outlet of the fan is communicated with the work chamber through an air duct, the left side of the work chamber is communicated with a sedimentation chamber, and the sedimentation chamber is communicated with an inlet of the fan through an air return pipeline. The system is simple in structure, the circulating air system of the fan->the air duct->the work chamber->the sedimentation chamber->the air return pipeline->the fan is formed, and therefore complicated dust removing equipment is omitted, production cost is reduced, and dust pollution is effectively prevented, and dust pollution generated in air is further avoided under the action of an air exhaust device.
