[0024] As Figures 1-4 shown, a superfine powder closed-loop fine screening and filling device includes a bracket 1. A container 8 is arranged at the upper left part of the bracket 1. A screening machine 12 is installed in the middle of the upper end of the bracket 1. The screening machine 12 is used to drive the powder to vibrate. A bin vibration housing 5 is installed at the upper right part of the bracket 1. A sealing cover 3 is arranged at the upper end of the container 8. A first exhaust filter element 9 is inserted and connected to the upper end of the sealing cover 3. The first exhaust filter element 9 is used to discharge the air inside the container 8. A lower closed bin 13 is arranged at the upper end of the screening machine 12. A filter screen 20 is arranged inside the lower closed bin 13. An ultrasonic transducer 19 is arranged at the front part of the lower closed bin 13. The upper end of the lower closed bin 13 is connected to an upper closed bin 14. The lower closed bin 13 and the upper closed bin 14 are detachably connected. A second exhaust filter element 15 is inserted and connected to the upper end of the upper closed bin 14. The second exhaust filter element 15 is used to discharge the air inside the upper closed bin 14. A bin 6 is arranged at the upper end of the bin vibration housing 5. By screening the powder in a sealed environment, it is possible to avoid environmental pollution to the site caused by dust and harm to the operators, improve safety, and the powder is in a sealed and penetrated state during screening, reducing external pollution during screening, ensuring the quality of the product, and at the same time preventing material loss during screening.
[0025] The lower end of the silo 6 is movably inserted into the silo vibration housing 5. The lower end of the silo 6 is connected to a second conveying pipeline 17. The lower end of the second conveying pipeline 17 is connected to a linear vibrator 21. The left end of the second conveying pipeline 17 movably penetrates the left side of the silo vibration housing 5. The linear vibrator 21 is installed inside the silo vibration housing 5. A stainless steel round bar with a diameter of 6 cm is built in between the silo 6 and the second conveying pipeline 17. It bounces up and down by means of the linear vibration frequency of the linear vibrator 21, and the powder completes natural and uniform free fall in the closed pipeline. The frequency of the linear vibrator 21 is adjustable, which is convenient for controlling the flow rate of the powder and meeting the screening requirements.
[0026] On the upper left part of the second conveying pipeline 17, a second co-frequency resonator 18 is installed. The second conveying pipeline 17 communicates with the upper closed silo 14. A flow limiting piece is arranged inside the second conveying pipeline 17, so that the powder flows uniformly and stably during the conveying process. The first co-frequency resonator 11 and the second co-frequency resonator 18 are used to solve the problem of adhesion and blockage between the powder and the conveying pipe wall during the closed-loop movement process. Steel balls are placed at the ends of the first conveying pipeline 10 and the second conveying pipeline 17. By means of the vibration frequencies of the linear vibrator 21 and the screening machine 12, they bounce up and down in a narrow space and repeatedly impact the pipe wall, so that the adhered powder falls off.
[0027] On the upper end of the upper closed silo 14, a material sensor 16 is arranged. The material sensor 16 is used to detect whether there is material in the upper closed silo 14.
[0028] The outer surface of the lower closed silo 13 is connected to the first conveying pipeline 10 in an inserted manner. The upper end of the first conveying pipeline 10 is installed with a first co-frequency resonator 11. The lower end of the first conveying pipeline 10 communicates with the container 8 through a hose.
[0029] At the front end of the silo vibration housing 5, a controller 2 is arranged. The controller 2 is installed on the bracket 1.
[0030] On the right end of the silo 6, a visualization panel 7 is arranged. The visualization panel 7 is used to conveniently observe the inside of the silo 6.
[0031] For a superfine powder closed-loop fine screening and filling device proposed by the present utility model, during use, 10 - 20 nm powder is put into the silo 6, the visualization panel 7 is closed, the linear vibrator 21 is turned on. With the assistance of the vibration assisting rod, the powder uniformly enters the second conveying pipeline 17. With the assistance of the second co-frequency resonator 18, it enters the upper closed silo 14 and the lower closed silo 13. Under the rotation of the screening machine 12 and the high-frequency vibration of the ultrasonic transducer 19, the powder gradually passes through the filter screen 20. Under the centrifugal force of the screening machine 12, the powder enters the first conveying pipeline 10. With the help of the first co-frequency resonator 11, it enters the container 8, and then the closed-loop fine screening process can be completed.
[0032] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model.
