Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular belongs to a hand-operated and electric-powered dual-purpose air separator. Background Art

[0002] The air separator is a device that uses the principle of airflow to sort materials. It is widely used in mining, metallurgy, chemical industry, agriculture and other industries. It adjusts the airflow speed so that materials of different density, shape and particle size produce different motion trajectories under the action of airflow, thereby realizing the separation and screening of materials. The air separator is mainly composed of a fan, air duct, screen and sorting chamber, etc. It can efficiently separate light impurities from heavier materials and is suitable for cleaning and screening of materials such as sand, grain and ore. The advantages of the air separator include high sorting accuracy, simple operation, low maintenance cost and low energy consumption. It can adapt to the processing needs of different materials, especially in the separation of light and heavy substances in material mixtures. The air separator is widely used in mineral processing, agricultural seed processing, waste recycling and other fields. It is an efficient and environmentally friendly sorting equipment.

[0003] Although the existing air separators are simple to operate and usually do not have a complex control system, they are relatively intuitive to operate. Workers can quickly master the use of them after simple training. They are also highly flexible and can adapt to the sorting needs of different materials. However, the operating efficiency is low, and manual adjustment of the airflow and material input speed is required. The operation process is relatively cumbersome, especially when processing large quantities of materials, and the workload of manual operation is very large.

[0004] Therefore, we propose a dual-purpose air separator with a flashlight. Summary of the invention
