[0021] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0022] like Figures 1 to 3 As shown, the high-efficiency, low-resistance cyclone dust collection device for solid waste grinding includes a feed channel 1, a dispersion device 2, a horizontal air outlet 3, a horizontal air outlet 4, a first upper air outlet 5, a second upper air outlet 6, a first dust collection plate 7, a second dust collection plate 8, an inner wall of the device 9, a first dust guide plate 10, a second dust guide plate 11, a fine dust outlet 12, a medium dust outlet 13, a coarse dust outlet 14, a connecting bin 15, a dust collection tray 16, a drive motor 17, a first monitoring device 18, and a second monitoring device 19. The dispersion device 2 is located above the horizontal air outlet 3, which has several horizontal air outlets 4. The first dust collection plate 7, the first dust guide plate 10, and the first upper air outlet 5 are used to separate fine materials from medium and coarse materials. The second dust collection plate 8, the second dust guide plate 11, and the second upper air outlet 6 are used to separate medium and coarse materials.

[0023] Feed channel 1 can be connected to the rear end of the grinding device.

[0024] Both the first dust collection plate 7 and the second dust collection plate 8 are cylindrical structures. The second dust collection plate 8 is located inside the inner wall 9 of the device, and the first dust collection plate 7 is located inside the second dust collection plate 8. A fine dust outlet 12 is formed on the inner side of the first dust collection plate 7, and an annular medium dust outlet 13 is formed between the first dust collection plate and the second dust collection plate 8. The feed channel 1 is located inside the first dust collection plate 7.

[0025] A connecting compartment is provided at the lower end of the inner wall 9 of the device.

[0026] The first dust guide plate 10 is positioned below the first dust collection plate 7, and the second dust guide plate 11 is positioned below the second dust collection plate 8. A first upper air outlet 5 is provided on the inner side of the first dust guide plate 10, corresponding to the fine dust outlet 12. A second upper air outlet 6 is formed between the first dust guide plate 10 and the second dust guide plate 11, corresponding to the medium dust outlet 13. A coarse dust falling channel is formed between the connecting chamber 15 and the second dust guide plate 11. A coarse dust outlet 14 is provided at the bottom of the connecting chamber 15.

[0027] Fine dust outlet 12 and medium dust outlet 13 are located at the top of the entire device, while coarse dust outlet 14 is located at the bottom of the entire device. Coarse dust outlet 14 can be connected to other collection devices. Larger diameter powder (coarse material) enters the collection device after being discharged from coarse dust outlet 14.

[0028] An upward airflow is generated through the first upper air outlet 5 and the second upper air outlet 6. The airflow speed of the first upper air outlet 5 and the second upper air outlet 6 can be adjusted so as to screen powders of different fineness.

[0029] In this embodiment, the first upper air outlet 5 is connected to the first fan via an air inlet pipe. The air generated by the first fan reaches the first upper air outlet 5 through the air inlet pipe and is blown upward through the first upper air outlet 5. In this embodiment, the second upper air outlet 6 is connected to the second fan via an air inlet pipe. The air generated by the second fan reaches the second upper air outlet 6 through the air inlet pipe and is blown upward through the second upper air outlet 6.

[0030] The horizontal air outlet 3 is located below the feed channel 1. The horizontal air outlet 3 can rotate to ensure that all dust is blown out evenly. The horizontal air outlets 4 are evenly arranged on the sides of the horizontal air outlet 3. The rotation of the horizontal air outlet 3 is driven by the drive motor 17, which is connected to the horizontal air outlet 3 through a transmission device, thereby driving the horizontal air outlet 3 to rotate.

[0031] The dispersing device 2 is located on top of the horizontal air outlet device 3; the dispersing device 2 has a conical structure so as to evenly distribute the powder around its perimeter.

[0032] The first dust collection plate 7 and the second dust collection plate 8 have a certain height, and the inner walls of the first dust collection plate 7 and the second dust collection plate 8 are smooth, so the friction between them is very small when they come into contact with the powder.

[0033] The first dust guide plate 10 is conical, and the diameter of its upper end is smaller than the diameter of its lower end. The second dust guide plate 11 is conical, and the diameter of its upper end is smaller than the diameter of its lower end.

[0034] The first monitoring device 18 is located on the outside of the first dust collection plate 7, and the second monitoring device 19 is located on the outside of the second dust collection plate 8.

[0035] The first monitoring device 18 and the second monitoring device 19 can determine whether the amount of powder and the wind speed need further adjustment by using the reaction force received by the first dust collection plate 7 and the second dust collection plate 8.

[0036] In this embodiment, both the first monitoring device 18 and the second detection device 19 use force sensors to monitor the magnitude of the force of the powder hitting the dust collection plate. If the force is too great, the feeding speed of the powder needs to be reduced to prevent the powder from being too dense and causing incomplete separation.

[0037] Turn on the drive motor 17 to start the device. The ground solid waste powder enters the device through the feed channel 1. The powder is evenly distributed on the dust collection tray 16 by the dispersion device 2. The powder is evenly blown out in all directions through the horizontal air outlet 4 on the horizontal air outlet device 3. By adjusting the wind speed of the first upper air outlet 4, the fine-sized powder is blown out from the fine dust outlet 12, while the medium and coarse-sized powder will fall onto the first dust guide plate 10 after contacting the first dust collection plate 7. By adjusting the wind speed of the second upper air outlet 5, the medium-sized powder is blown out from the medium dust outlet 13, while the coarse-sized powder will fall onto the second dust guide plate 11 after contacting the second dust collection plate 8. Then, it enters the coarse dust outlet 14 through the coarse dust falling channel and is discharged, completing the separation of the three particle sizes.

[0038] By monitoring the reaction force of the dust collection plate with a monitoring device and adjusting the airflow of the exhaust device, the range of separated particle sizes can be adjusted.

[0039] The scope of protection of this utility model is not limited to the above embodiments. Any modifications, equivalent substitutions, and improvements that can be made by those skilled in the art within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
