The reference numbers in the drawings: 1. a winnowing bin; 2. a light refuse pipe; 3. a cyclone separator; 4. an air suction pipe; 5. a fan; 6. a venturi tube; 7. a heavy garbage accumulation tank; 8. an air inlet pipe; 9. a conveyor belt; 10. an air lock device.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
Example (b): as shown in the attached figure 1, the venturi tube airflow sorting device of the utility model comprises a coherent closed channel which is composed of a winnowing bin 1, a light garbage pipeline 2, a cyclone separator 3, an air suction pipe 4, a fan 5, a venturi tube 6, a heavy garbage accumulation tank 7 and an air inlet pipe 8, wherein the winnowing bin 1 and the cyclone separator 3 are vertically arranged, the winnowing bin 1 is a vertical winnowing bin with openings at the upper end and the lower end, the light garbage pipeline 2 is horizontally welded at the top end of the winnowing bin 1 and is communicated with the winnowing bin 1, one end of the light garbage pipeline 2, which is far away from the winnowing bin 1, is fixed on the outer wall of the cyclone separator 3 and is communicated with the cyclone separator 3, one end of the air suction pipe 4 is inserted into the cyclone separator 3 from the top down from the middle part of the cyclone separator 3, one end of the air suction pipe 4, which is far away from the cyclone separator 3, is communicated with an air inlet of the fan 5, the venturi tube 6 is vertically arranged at the bottom end of the winnowing bin 1 and is communicated with the winnowing bin 1, heavy garbage pile up jar 7 and install in the bottom of venturi 6 and communicate with the bottom of venturi 6, the one end of air-supply line 8 and the air-out end intercommunication of fan 5, the other end is fixed on the outer wall of heavy garbage pile up jar 7 and is communicated with heavy garbage pile up jar 7, is equipped with the feed inlet on the lateral wall of selection by winnowing storehouse 1.
