[0025] This application provides a screening device for iron filings recycling, which effectively solves the shortcomings of traditional screening devices in terms of screen cleaning. The screen is easily clogged by iron filings, and there is a lack of effective cleaning measures. Once clogged, it not only affects the screening effect, but also requires frequent shutdowns for manual cleaning, further reducing work efficiency and increasing labor and equipment maintenance costs. Through the synergistic effect of cleaning cotton strips 25 and cleaning brushes 27, a dual protection mechanism for screen cleaning is formed. The cleaning cotton strips 25 prevent dust adhesion, and the cleaning brushes 27 solve the problem of iron filings clogging. From different angles, the working condition of the screen is guaranteed, reducing the probability of screen failure caused by clogging and dust accumulation, and improving the stability and reliability of equipment operation.
[0026] Example
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the shortcomings of traditional screening devices in terms of screen cleaning. The screen is easily blocked by iron filings and lacks effective cleaning measures. Once blocked, it not only affects the screening effect, but also requires frequent shutdowns for manual cleaning, which further reduces work efficiency and increases labor and equipment maintenance costs. The overall idea is as follows: A screening device for iron filings recycling includes a base 11. Fixing strips 12 are symmetrically fixedly installed on the upper end of the base 11. A collection box 13 is slidably installed inside the base 11. A drive motor 14 is fixedly installed on the fixing strip 12 on the left side. A rotating shaft 15 is fixedly installed on the output end of the drive motor 14. The two ends of the rotating shaft 15 are respectively rotatably installed in the two fixing strips 12. A drum screen body 16 is fixedly installed on the rotating shaft 15. A first feeding port 17 is opened on the side wall of the drum screen body 16. Arc grooves 18 are evenly and equidistantly opened on the side wall of the drum screen body 16. A screen 19 is inserted into each arc groove 18.
[0028] Cleaning mechanisms are fixedly installed on the opposite ends of the two fixing strips 12;
[0029] The cleaning mechanism includes two fixed plates 22, which are respectively fixedly installed on the opposite ends of two fixed bars 12. Each of the two fixed plates 22 has a second feeding port 23, which is directly opposite to the two first feeding ports 17. In use, iron filings can be first fed into the drum screen body 16 through the second feeding port 23 and the first feeding port 17. Then, the drive motor 14 can be started. Under the action of the drive motor 14, the rotating shaft 15 will be rotated, which will in turn drive the drum screen body 16 to rotate. Under the rotation of the drum screen body 16, the iron filings inside will be turned over by gravity. At this time, the smaller iron filings will be filtered by the screen 19 and fall into the collection box 13 for collection. The larger iron filings will remain in the drum screen body 16. When it is necessary to remove them, one of the screens 19 can be removed by the positioning bolt 21. As the drum screen body 16 rotates, the iron filings will be discharged. The dynamic turning allows the iron filings to pass through the screen more quickly, greatly shortening the screening time and processing more iron filings per unit time, thus improving the overall recycling efficiency.
[0030] Two horizontal bars 24 are fixedly installed on the inner walls of the two second feeding ports 23. Each screen 19 is symmetrically threaded with positioning bolts 21, and each screen 19 is detachably installed on the drum screen body 16 via the positioning bolts 21. Cleaning strips 25 are fixedly installed at the upper end of the horizontal bars 24, adhering to the inner wall of the screen 19. Fixing rings 26 are symmetrically fixedly installed at the lower end of the horizontal bars 24, and cleaning brushes 27 are symmetrically fixedly installed on the two fixing rings 26, adhering to the inner wall of the screen 19. The two cleaning brushes 27 are distributed at a 45° angle within the drum screen body 16. When screening iron filings, the screen 19 rotates with the drum screen body 16, and the cleaning strips 25 will adhere to the inner wall of the screen 19. Since the cleaning cotton strip 25 is located at the top, it will not come into contact with the iron filings. It can clean the screen 19 after screening the iron filings, ensuring that the screen 19 is not easily contaminated with dust. The two cleaning brushes 27 are located at the bottom. When the iron filings clog the screen 19 during screening, the two cleaning brushes 27 will rub against the screen 19 to clear the blockage. Through the synergistic effect of the cleaning cotton strip 25 and the cleaning brushes 27, a dual protection mechanism for screen cleaning is formed. The cleaning cotton strip 25 prevents dust adhesion, and the cleaning brushes 27 solve the blockage of iron filings. From different angles, the working condition of the screen is guaranteed, reducing the probability of screen failure caused by blockage and dust accumulation, and improving the stability and reliability of equipment operation.

[0032] in:
[0033] Base 11: Made of high-strength steel, it has a rectangular plate structure. Anti-slip pads or anchor bolts can be installed on its bottom to ensure stable installation on the working ground and to ensure the stability of the entire screening device during operation. The base 11 is equipped with a slide rail with a T-shaped or dovetail-shaped cross-section. The slide rail cooperates with the sliders on both sides of the collection box 13 to realize the sliding installation of the collection box 13 inside the base 11, which facilitates the pulling and cleaning of the collection box 13.
[0034] Fixing strip 12: Symmetrically fixedly installed on the upper end of the base 11, also made of high-strength steel. The fixing strip 12 is fixed to the base 11 by welding or bolt connection. The inner side of the fixing strip 12 is provided with bearing mounting holes for installing the bearing of the rotating shaft 15 to ensure that the rotating shaft 15 can rotate flexibly. The outer side is provided with a mounting plate for fixing the drive motor 14. The mounting plate is provided with mounting holes adapted to the drive motor 14. The drive motor 14 is firmly fixed to the fixing strip 12 on the left side by bolts.
[0035] Collection box 13: Made of stainless steel, it is rectangular in shape and its size matches the slide rail inside the base 11. The front end of the collection box 13 is equipped with a handle made of engineering plastic with anti-slip texture on the surface, making it easy for operators to pull the collection box 13. The bottom of the collection box 13 is equipped with reinforcing ribs to enhance its load-bearing capacity and prevent deformation when collecting a large amount of iron filings. The inside of the collection box 13 can be sprayed with an anti-rust coating to further improve its service life.
[0036] Drive motor 14: A three-phase asynchronous motor is selected, and its power is reasonably selected according to the size and weight of the drum screen body 16 to ensure that it can provide enough power to drive the drum screen body 16 to rotate. The output shaft of the drive motor 14 is connected to the rotating shaft 15 through a coupling. The coupling adopts a flexible coupling, which can compensate for the misalignment between the two shafts and reduce the transmission of vibration and noise. The drive motor 14 is connected to an external power supply and control switch through wires. The control switch can be set on the side of the base 11 for convenient start and stop operation by the operator.
[0037] The drum screen body 16 is cylindrical in shape and is made of rolled and welded stainless steel sheet. The number and size of the arc grooves 18 are adapted to the screen mesh 19. The depth of the arc grooves 18 can ensure that the screen mesh 19 fits tightly with the drum screen body 16 after installation, preventing iron filings from leaking out from the gaps. The two ends of the drum screen body 16 are fixed to the rotating shaft 15 by welding or bolt connection to ensure that the drum screen body 16 remains stable during rotation.
[0038] Screen 19: Stainless steel wire mesh is selected, and its mesh size is selected according to the required particle size of the iron filings. For example, for screening finer iron filings, an 80-120 mesh screen can be selected; for screening coarser iron filings, a 20-60 mesh screen can be selected. The shape of screen 19 is arc-shaped, which matches the shape of arc-shaped groove 18.
[0039] Horizontal bar 24: It is fixedly installed in the inner wall of the two second feeding ports 23. It is made of stainless steel and is long and narrow. The length of the horizontal bar 24 is adapted to the circumference of the inner wall of the second feeding port 23. It is fixed to the inner wall of the second feeding port 23 by welding or bolt connection. The horizontal bar 24 provides the installation base for cleaning cotton strip 25 and cleaning brush 27.
[0040] Cleaning cotton strip 25: Made of cotton material, it has good adsorption and softness. The cleaning cotton strip 25 can clean the screen 19 after screening iron filings, adsorb dust and fine impurities on the surface of the screen 19, and prevent dust from adhering to the screen and affecting the screening effect.
[0041] Fixing ring 26: Made of stainless steel, it is circular in shape. The inner diameter of the fixing ring 26 is matched with the diameter of the mounting rod of the cleaning brush 27 and is used to fix the cleaning brush 27.
[0042] Cleaning brush 27: It consists of a handle and bristles. The handle is made of engineering plastic, which has a certain strength and toughness. The bristles are made of nylon, which has good wear resistance and elasticity. As the drum screen body 16 rotates, the two cleaning brushes 27 will rub against the screen 19 to clear the blockage and ensure that the screen holes of the screen 19 remain unobstructed, thus ensuring the normal operation of the screening work.
[0043] Working principle:
[0044] First, when using the device, the iron filings can be fed into the drum screen body 16 through the second feed port 23 and the first feed port 17. Then, the drive motor 14 can be started. Under the action of the drive motor 14, the rotating shaft 15 will be rotated, which will in turn drive the drum screen body 16 to rotate. Under the rotation of the drum screen body 16, the iron filings inside will be turned over by gravity. At this time, the smaller iron filings will be filtered by the screen 19 and fall into the collection box 13 for collection. The larger iron filings will remain in the drum screen body 16. When it is necessary to remove them, one of the screens 19 can be removed by the positioning bolt 21. As the drum screen body 16 rotates, the iron filings will be discharged. The dynamic turning allows the iron filings to pass through the screen more quickly, greatly shortening the screening time. More iron filings can be processed per unit time, improving the overall recycling efficiency.
[0045] In the second step, during the screening of iron filings, the screen 19 rotates with the drum screen body 16, and the cleaning strip 25 contacts the inner wall of the screen 19. Since the cleaning strip 25 is located at the top, it will not come into contact with the iron filings. It can clean the screen 19 after screening the iron filings, ensuring that the screen 19 is not easily contaminated with dust. The two cleaning brushes 27 are located at the bottom. When the iron filings clog the screen 19 during screening, the two cleaning brushes 27 will rub against the screen 19 to clear the blockage. Through the synergistic effect of the cleaning strip 25 and the cleaning brushes 27, a dual protection mechanism for screen cleaning is formed. The cleaning strip 25 prevents dust adhesion, and the cleaning brushes 27 solve the problem of iron filings clogging. From different angles, the working condition of the screen is guaranteed, reducing the probability of screen failure caused by clogging and dust accumulation, and improving the stability and reliability of equipment operation.
[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
