[0027] In this embodiment, mesh holes are provided in the sealing shell 2 on both the primary friction roller 3 and the secondary friction roller 4. By setting the mesh holes, the residue and sewage when cleaning the metal particles can be discharged through the mesh holes, and the metal particles can be intercepted and filtered so that they will not be discharged through the mesh holes. Two receiving covers 15 are fixedly installed at the bottom of the sealing shell 2. The bottoms of the two receiving covers 15 are fixedly connected to lifting conveyors 16. The ends of the two lifting conveyors 16 away from the corresponding receiving covers 15 are fixedly connected to discharge pipes 17. The two receiving covers 15 can be used to receive the residue discharged from the mesh holes. The residue can be transported by the lifting conveyor 16 so that the residue is discharged from the discharge pipe 17.

[0029] In the present embodiment, it should be noted that the first variable frequency motor 5, the second variable frequency motor 11, and the lifting conveyor 16 can all be purchased on the market. The first variable frequency motor 5, the second variable frequency motor 11, and the lifting conveyor 16 are equipped with power supplies, and their line connection methods and control methods are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

[0030] Through the above structure, the novel double-stage friction drum cleaning machine provided by the present application can achieve the effect of double-stage cleaning of metal particles when in use, thereby improving the quality of cleaning of metal particles. During specific operation, by controlling the second variable frequency motor 11 to run, the second variable frequency motor 11 drives the second main gear 12 to rotate, and the second main gear 12 drives the second sub-gear 13 and the spiral feed shaft 10 to rotate, and the metal particles to be cleaned are continuously poured from the feeding hopper 9 into the conveying cylinder 8, and the rotation of the spiral feed shaft 10 can be used to gradually convey the metal particles to the inside of the primary friction drum 3, and the clean water is controlled to be sprayed out through the water injection pipe joint 18 and the water spray pipe in sequence, so that the clean water enters the first friction drum 3 and the second friction drum 4 through the mesh, and the first variable frequency motor 5 is controlled to run forward, and the first variable frequency motor 5 drives the first main gear 6 to rotate forward, and the first main gear 6 drives the first sub-gear 7, the primary friction drum 3 and the secondary friction drum 4 to rotate clockwise. At this time, the metal particles entering the primary friction drum 3 The metal particles utilize the spiral ribbon blades arranged inside thereof to rub and roll with the lifting plate (since the spiral ribbons in the primary friction roller 3 and the secondary friction roller 4 are arranged in opposite directions, the metal particles cannot move from the primary friction roller 3 to the secondary friction roller 4 at this time), achieving the effect of primary cleaning. After the metal particles are cleaned for a period of time inside the primary friction roller 3 according to the cleaning requirements, the first variable frequency motor 5 is controlled to run in reverse, so that the primary friction roller 3 and the secondary friction roller 4 can rotate counterclockwise. At this time, the metal particles in the primary friction roller 3 will gradually enter the secondary friction roller 4. The metal particles entering the secondary friction roller 4 utilize the spiral ribbon blades arranged inside thereof to rub and roll with the lifting plate, achieving the effect of secondary cleaning. After the secondary cleaning of the metal particles entering the secondary friction roller 4 is completed, the first variable frequency motor 5 is controlled to run forward again. At this time, the metal particles inside the secondary friction roller 4 will gradually be discharged from the discharge pipe 14.

[0031] Therefore, when the primary friction roller 3 and the secondary friction roller 4 are controlled to rotate synchronously clockwise, the metal particles rub against each other and roll inside the primary friction roller 3 (since the spiral belt is set in the opposite direction, the metal particles will not move forward into the secondary friction roller 4) for primary cleaning, and at this time the metal particles inside the secondary friction roller 4 will be discharged to the discharge pipe 14; when the primary friction roller 3 and the secondary friction roller 4 are controlled to rotate synchronously counterclockwise, the metal particles in the primary friction roller 3 will be discharged into the secondary friction roller 4, and at this time the metal particles in the secondary friction roller 4 rub against each other and roll for secondary cleaning; and then the cleaning effect is controlled by using the first variable frequency motor 5 to control the alternating time of the forward and reverse rotation of the primary friction roller 3 and the secondary friction roller 4, so as to achieve the effect of double-stage cleaning of the metal particles, improve the cleaning quality, and realize the function that the existing single-stage friction roller cannot achieve.
