In this embodiment, the material distributor 3 has a cone-shaped structure with an upward tip, and the material entering the casing 1 through the material inlet 11 forms a material waterfall on the cone-shaped structure and falls down into the air separation compartment 14.
In this embodiment, a side wall of the air separation compartment 14 is disposed in a common wall with the housing 1, and an observation window 17 made of a transparent material is formed. Except that one side wall of the air separation cabin 14 is arranged on the same wall as the shell 1, other side walls of the air separation cabin 14 are arranged at intervals with the shell 1.
In this embodiment, the return air structure 42 is provided with a filter material. The filter material specifically adopts a filter screen.
In this embodiment, the air outlet structure 41 includes an annular air outlet pipe 411, a central axis of the annular air outlet pipe 411 is located in a height direction of the air separation chamber 14, and air outlets are distributed on the annular air outlet pipe 411.

The circulating tower type winnowing machine has the working principle that materials (grains) enter the shell 1 from the buffer hopper 2, form a material fall through the cloth 3 and uniformly fall into the winnowing cabin 14. The fan 43 generates air flow, and the air flows into the winnowing cabin 14 through the air outlet pipeline and the annular air outlet 411 to sweep the falling materials. Under the action of the air flow, lighter impurities (such as chaff, dust and the like) in the material are blown up and enter the impurity collecting compartment 16 along with the air flow, and heavier materials (grains) fall into the material outlet at the bottom of the winnowing compartment 14. The air flow entering the impurity collection compartment 16 is filtered by the filter material on the return air structure 42, is sucked by the fan and enters the circulation again, so as to form a continuous winnowing process. The sorted materials are discharged from the material outlet 12, and the impurities are discharged from the impurity outlet 13, so that the effective separation of the materials and the impurities is realized.
The circulating tower type winnowing machine has a simple structure and is easy to manufacture and maintain. The interior of the shell is divided into a winnowing cabin, an equipment cabin and an impurity collecting cabin by a partition board, and the layout is compact and reasonable. The material distributor adopts a cone-shaped design, so that the materials can be uniformly dispersed into a waterfall shape, and the winnowing efficiency and the sorting precision are improved. The air circulation system forms continuous circulation winnowing, fully utilizes air flow and saves energy consumption. The winnowing cabin is provided with a transparent observation window, so that the winnowing process can be observed conveniently, and the technological parameters can be adjusted in time. The bottom of the winnowing cabin and the bottom of the impurity collecting cabin are both conical discharge hoppers, so that the automatic discharge of materials and impurities is facilitated, and the blockage is avoided. The return air is filtered through the filtering material, so that the impurity backflow is prevented, and the system cleaning and wind selection effects are ensured. Through adjusting fan power, can control selection by winnowing intensity in a flexible way, adapt to the separation demand of different materials. The circulating tower type winnowing machine fully utilizes the separation effect of air flow on the mixture, has ingenious structural design, reasonably passes through materials, realizes the efficient separation of the materials and light impurities, has good application prospect, and is particularly suitable for the cleaning and classification of grain and other particle materials.
