[0029] A protective shell 3 is fixedly provided on the top surface of the sub-screening box 1, and the protective shell 3 and the sub-screening box 1 are connected through and through. A horizontal plate 4 is fixedly provided on the inner wall of the protective shell 3 in the transverse direction, and the center of the horizontal plate 4 is a hollow area. A circular groove 5 is provided on the inner wall of the horizontal plate 4, and the circular groove 5 is arranged on the inner wall of the hollow area. A circular ring 6 is provided in the inner cavity of the circular groove 5 for sliding adaptation. A fixing block 7 is fixedly provided on the inner wall of the circular ring 6, and an air pipe 8 is provided in the inner cavity of the fixing block 7. One end of the air pipe 8 penetrates to the top surface of the protective shell 3 and is connected to the outer surface of the protective shell 3. There are an air pump and a water tank. The end of the air pipe 8 away from the external water tank is arranged in the upper half of the inner cavity of the screening box 1, and an air hood is fixedly provided. When dust and rust are generated during the screening process, the external air pump is turned on to allow the air pump to extract the dust and rust in the screening box 1 through the air pipe 8 and the air hood, and the extracted dust and rust will move along the air pipe 8 to the external water tank, and through the external atomizing nozzle of the water tank, the water mist sprayed by the atomizing nozzle will spray the dust and rust for dust reduction treatment.
[0030] The top surface of the protective shell 3 is fixed with a driving motor 10 through the bottom plate. The driving motor 10 can rotate forward and reverse, and the air pipe 8 is set with a soft material. The output shaft of the driving motor 10 passes through the bottom plate and the protective shell 3 and extends to the inner cavity of the circular groove 5, which is connected with a gear 11. The peripheral side of the ring 6 is installed with teeth 9 meshing with the gear 11. The gear 11 and the teeth 9 are in the same horizontal plane. In the process of extracting dust and dust, the driving motor 10 is turned on to drive the gear 11 to rotate, and the gear 11 can drive the ring 6 to rotate through the meshing teeth 9, and cooperate with the forward and reverse rotation of the driving motor 10, so that the ring 6 can drive the air pipe 8 to rotate forward and reverse through the fixed block 7. Rotation, thereby expanding the range of dust and dust extraction by the air pipe 8, and being able to better extract dust and dust into the water tank for spray dust reduction treatment, reducing the situation where dust and dust will be scattered in the air during screening, and reducing the impact on the physical and mental health of the staff. The top surface of the ring 6 and the top wall of the inner cavity of the circular groove 5 can be respectively provided with a T-shaped limit groove 17 and a limit block 18. When the gear 11 drives the ring 6 to rotate through the teeth 9, the ring 6 will drive the limit block 17 to rotate in the inner cavity of the limit groove 18, so that the limit block 17 and the limit groove 18 can limit the position of the ring 6 to ensure that when the ring 6 rotates, it will always rotate with the center point of the hollow area as the origin.
[0031] A bearing is provided on the inner wall of the hole through which the air pipe 8 passes in the fixed block 7, and the circumferential side of the air pipe 8 is arranged on the inner wall of the bearing, so that when the ring 6 drives the air pipe 8 to rotate through the fixed block 7, the air pipe 8 will not rotate along with the rotation of the fixed block 7, to avoid that the air pipe 8 will be tightened and unable to be extracted after following the rotation of the fixed block 7, and the driving motor 10 will first drive the ring 6 to rotate clockwise by 360 degrees, and then rotate counterclockwise by 360 degrees, so as to perform a second restriction on the air pipe 8, to avoid that the air pipe 8 will be twisted together due to rotation.
[0032] The bottom surfaces of the two screen plates 2 are provided with collecting boxes 13 for collecting metal mixtures through fixed horizontal blocks. The two collecting boxes 13 are respectively connected to the two fixed horizontal blocks in a sliding manner. When the screen plate 2 screens the metal mixture, the metal mixture smaller than the size of the through hole inside the screen plate 2 will pass through the through hole and fall into the collecting box 13 for collection, while the metal mixture larger than the through hole will continue to move along the inclined surface of the screen plate 2. Since two screen plates 2 are provided, the metal mixture can be screened twice, and the two collecting boxes 13 are respectively connected to the two fixed horizontal blocks in a sliding manner, so that the screening is completed. After completion, the collecting box 13 can be taken out from the fixed horizontal block to process the collected metal mixture. A collecting cabinet 14 is provided on one side of the bottom surface of the inner cavity of the screening box 1. When the size of the metal mixture is larger than the size of all through holes, it will fall along the inclined surfaces of the two screen plates 2 into the collecting cabinet 14 for collection, so that the metal mixture of different sizes can be screened. The top surface height of the collecting cabinet 14 is lower than the bottom surface height of the collecting box 13 below, so that the collecting cabinet 14 can select different sizes according to actual conditions below the collecting box 13, and can collect the metal mixture with a larger capacity.
[0033] Slide grooves 15 are provided on the inner walls of both sides of the sub-screening box 1 and on one side of the two screen plates 2 respectively. Slide blocks 16 are fixedly provided on the opposite sides of the two screen plates 2. The two slide grooves 15 and the two slide blocks 16 are arranged in an inclined T-shape, and a box door can be provided on one side of the sub-screening box 1. When the through holes inside the screen plate 2 are blocked, the box door can be opened and the screen plate 2 can be dragged, so that the screen plate 2 can drive the slide block 16 to move in the inner cavity of the slide groove 15, so that the screen plate 2 can be taken out for cleaning. When the cleaning is completed and the slide block 16 is put into the slide groove 15 again, one side of the screen plate 2 will abut against one side wall of the sub-screening box 1. At this time, closing the box door can make the box door abut against the other side wall of the screen plate 2, thereby achieving the effect of restricting the screen plate 2.
[0034] Working principle:
[0035] The sieving device for recycling metal mixtures puts the metal mixtures to be sifted into the sieving box 1 through the feed port 12 for sifting, and the metal mixtures entering the sifting box 1 will move along the sieve plates 2 inclined downward at two angles. When the size of the metal mixtures is smaller than the size of the through holes inside the sieve plates 2, they can pass through the sieve plates 2 and fall into the collection box 13 for collection, while the metal mixtures larger than the size of all the through holes will fall into the collection cabinet 14 for collection. When the metal mixtures are sieved and the dust and rust on the surface of the metal mixtures are scattered on the sieves, the metal mixtures will be sieved. When in the box 1, turn on the external air pump, and let the air pump extract the dust and dust in the screening box 1 through the air pipe 8 and the air hood, so that the dust and dust can enter the external water tank, and be sprayed through the atomizing nozzle for dust reduction treatment. At this time, turn on the drive motor 10, and let the drive motor 10 drive the ring 6 to rotate through the gear 11 and the teeth 9, and then drive the air pipe 8 to make a circular motion through the fixed block 7, thereby expanding the extraction range of the air pipe 8, which can better suppress dust, reduce the situation where dust and dust will be scattered in the air during screening, and reduce the impact on the physical and mental health of the staff.
