The dust removal machine 03 uses a dust collector 22 to periodically remove dust. Filter bag 21 effectively removes dust. Its beneficial effects are: First, the device achieves efficient separation of heavy materials, light materials, and dusty materials, while ensuring high purity and cleanliness of the separated materials. This results in a clean and well-ventilated production area and subsequent operations involving heavy materials, allowing machinery to operate smoothly without disruption, extending its service life, and effectively protecting worker health. Furthermore, the high purity of materials at each stage facilitates material recycling. Second, the heavy material primary separator 1 adopts a rotary structure with circumferentially distributed material chambers, enabling reciprocating feeding and throwing. The material is also affected by gravity and... Centrifugal force allows heavier materials to have greater kinetic energy, making it easier to separate lighter materials. This results in high sorting accuracy. The material-carrying chamber is in close contact with the inner wall, effectively sealing and isolating the separation chamber to prevent airflow leakage caused by gaps, thus eliminating dust. Simultaneously, the tight contact and sealing protects the shell wall from friction damage, ensuring long-term effective sorting. Thirdly, the light material re-sorter 02 uses a cleaning and unclogging section 3 to periodically blow air and clean the inner filter cartridge 7, preventing material from clogging the separator. This maintains high separation efficiency for a long time, efficiently utilizing energy and requiring minimal maintenance, effectively reducing costs. This reduces maintenance costs, improves equipment efficiency, increases sorting speed, and eliminates the need for additional space. The overall equipment is compact, and the airlock unloader 4 features a flexible interference connection to several circumferential arrays of rotating unloading chambers 40, achieving high-sealing continuous unloading. The airlock unloader 4 also uses a rotary wheel module 5 for high-sealing continuous unloading, ensuring that the separator experiences no air pressure loss and no blockage during unloading.

[0052] Preferably, the lower end of the dust collection chamber 20 is connected to a three-dimensional frame structure, and a threaded support rod is fixedly connected in the middle of the frame. The advantage of this design is that the frame has high strength.

[0053] Preferably, the screw conveyor 030 is connected to the base frame via side beams at both ends; the screw conveyor 030 is equipped with an air valve 032. Its advantages are: this configuration results in less air loss and better dust removal.

[0054] Furthermore, the rotating shaft 51 of the rotary module 5 is rotatably connected to the first seated bearing 57 on the front and rear walls of the cylindrical receiving chamber, and its extended end is directly connected to the initial sorting motor 50. Several radially arranged radial dividing plates 52 are connected to the rotating shaft 51 at their inner ends and to the elastic strips 54 at their outer ends, and are fixed to the front and rear side cover plates 53, forming multiple fan-shaped material loading chambers 500. The beneficial effects are: First, compared with multi-mesh vibrating screens, the radial dividing plates 52 have a higher load-bearing capacity, do not deform after long-term use, have a long service life, reduce maintenance and replacement costs, and effectively improve screening efficiency. Second, the elastic strips 54 are in close contact with and seal the inner wall of the cylindrical body, effectively sealing and isolating the separation chamber and the cavity of the cylindrical body, avoiding airflow leakage caused by the intermediate gap, eliminating dust, improving the working environment, and protecting the machine's service life. After the radial dividing plates 52 are slightly deformed by long-term impact loads, the elastic strips 54 provide a buffer space, which can still be in close contact and seal and protect the cylindrical body from friction damage, enabling long-term effective sorting.

[0055] The elastic strip 54 of the rotary module 5 is located between the pressure plate 55 and the radial dividing plate 52, and the three are connected by threaded parts.

[0059] The airflow passes from bottom to top through the light and heavy separation chamber 101; the initial separation motor 50 drives the rotating wheel module 5 to rotate, the material loading chamber 500 is loaded at the inlet and rotates to the arc-shaped outlet. Under the dual action of gravity and centrifugal force, the material enters the light and heavy separation chamber 101 from the material loading chamber 500 through the arc-shaped discharge port. The heavy material falls from the heavy material outlet 103, and the light material and the mixture fly out from the mixed flow outlet 104 under the action of wind, thus realizing the separation of light and heavy materials.

The differential pressure controller is electrically connected to a first pressure sensor and a second pressure sensor. The first pressure sensor is located inside the settling shell 020, and the second pressure sensor is located inside the drain pipe 021. When the pressure difference between the settling shell 020 and the drain pipe 021 is higher than a standard value, the differential pressure controller stops the initial sorting motor 50 and starts the cleaning rotating part 6 and the unblocking fan 36 to perform cleaning, unblocking, and dust removal. Its advantages are: this setup facilitates real-time unblocking and is beneficial for achieving automated sorting.

[0063] Furthermore, the cleaning motor 60 of the cleaning rotating part 6 is fixedly connected to the side frame 63 of the settling shell 020 via the coupling 62.

[0071] The cleaning rotating part 6 drives the filter cartridge 7 to rotate circumferentially, and the unblocking blower 36 starts to make the cleaning head 33 blow the light material on the filter cartridge 7 below into the light material outlet to unblock it;

[0072] The unblocking fan 36, the external air inlet pipe 35, the internal transfer pipe 34, the core cylinder 31, and the cleaning head 33 are interconnected to form a blowing passage. The cleaning rotating part 6 drives the filter cartridge 7 to rotate, and the cleaning head 33 blows away the light material stuck on the filter cartridge 7.

[0073] Furthermore, the outer peripheral wall of the circular frame 70 is connected to the circular filter screen 71, and the inside of the filter cartridge 7 is a dust flow path, while the external space surrounding the filter cartridge 7 forms a lightweight material passage.
