Description

Technical Field

[0001] This utility model relates to the field of iron filings screening, and in particular to a screening device for iron filings recycling. Background Technology

[0002] In the machining industry, scrap metal recycling is a crucial step in improving resource utilization and reducing production costs. Scrap metal screening, as a key step in the recycling process, directly impacts recycling efficiency and quality. Currently, most scrap metal screening machines on the market employ fixed screen structures, using vibration or rotation to classify and screen scrap. However, such equipment commonly suffers from screen clogging issues in practical applications: on the one hand, scrap metal, due to its irregular shape and adhesion, easily gets stuck in the screen openings, significantly reducing screening efficiency; on the other hand, some screening machines lack effective anti-clogging measures, requiring frequent shutdowns for manual screen cleaning, increasing operator workload, causing equipment wear and tear, and significantly reducing production continuity. Furthermore, traditional screening devices often rely on a single screening layer for grading, making it difficult to meet the needs of fine separation of scrap metal of different particle sizes, thus hindering the in-depth application of scrap metal recycling. Utility Model Content

[0003] In order to overcome the shortcomings of existing iron scrap screening machines that are prone to screen clogging, the technical problem to be solved is to provide a screening device for iron scrap recycling that prevents screen clogging.

[0004] The technical solution is as follows: A screening device for iron filings recycling includes a support frame. The lower ends of four springs are fixedly connected to the four corners of the top of the support frame. The upper ends of the springs are connected to the bottom of the screening machine to form an elastic support structure. A screen is horizontally arranged inside the screening machine. Cylinders are symmetrically installed on the inner walls of the front and rear sides of the screening machine. The piston rod of the cylinder is fixedly connected to a fixing block. The front and rear fixing blocks are connected by a connecting plate. The two sides of the connecting plate are firmly connected to the fixing blocks. Elastic brushes are evenly arranged at the bottom of the fixing blocks, and the brush bristles are closely attached to the surface of the screen. A telescopic belt is also provided inside the screening machine, and the telescopic belt is arranged around the cylinder.

[0005] Furthermore, it also includes a mounting plate. The mounting plate is fixedly installed on the lower left side inside the screening machine. A connecting block is fixedly connected to the mounting plate. Four nozzles are evenly distributed on the connecting block. The nozzles can spray high-pressure gas onto the screen surface, which, together with the elastic brush, achieves double cleaning of the screen and effectively removes iron filings adhering to the screen.

[0006] Furthermore, it also includes a lighting lamp, which is fixedly connected to the top left side of the screening machine to provide sufficient illumination for the screening process.

[0007] Furthermore, it also includes a warning light. A warning light is fixedly connected to the front right side of the support frame. When the equipment experiences abnormal vibration, motor overload, or screen blockage, the warning light will automatically light up to remind the operator to handle the situation in a timely manner.

[0008] Furthermore, it also includes a storage box, which is fixedly connected to the front left side of the support frame for collecting qualified iron filings after screening.

[0009] Furthermore, it also includes a toolbox, which is fixedly connected to the left side of the support frame for storing tools and accessories required for daily equipment maintenance.

[0010] The beneficial effects of this utility model are as follows: the elastic support structure reduces vibration loss, the cylinder drives the elastic brush and the high-pressure nozzle to work together to achieve dual anti-clogging of the screen by mechanical cleaning and airflow flushing, which greatly reduces the risk of material blockage. The telescopic belt protects the cylinder to ensure stable operation. The lighting and warning lights ensure operational safety and facilitate fault early warning. The storage box and toolbox are designed to improve the recycling process and maintenance convenience, effectively solving the problem of material blockage in traditional screening machines and significantly improving the efficiency of iron filings screening and the reliability of the equipment.

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] Example: A screening device for iron filings recycling, such as... Figure 1-4As shown, the system includes a support frame 1, springs 2, a screening machine 3, a screen 4, cylinders 5, fixing blocks 6, connecting plates 7, and elastic brushes 8. The support frame 1 has four springs 2 fixedly connected to its four corners at the top. The upper ends of the springs 2 are connected to the bottom of the screening machine 3. The screen 4 is horizontally arranged inside the screening machine 3. Cylinders 5 are symmetrically installed on the inner walls of the front and rear sides of the screening machine 3. The piston rods of the cylinders 5 are fixedly connected to the fixing blocks 6. The front and rear fixing blocks 6 are connected by the connecting plates 7. The connecting plates 7 are securely connected to the fixing blocks 6 on both sides. Elastic brushes 8 are evenly arranged at the bottom of the fixing blocks 6, with their bristles tightly adhering to the surface of the screen 4. The screening machine 3 also has a telescopic belt 9 inside, which surrounds the cylinders 5. The system also includes a mounting plate 10, connecting blocks 11, and nozzles 12. The mounting plate 10 is fixed to the lower left side inside the screening machine 3, with four nozzles 12 evenly distributed on the plate. The nozzles 12 can spray high-pressure gas onto the surface of the screen 4. It also includes a lighting lamp 13, which is fixedly connected to the top left side of the screening machine 3. It also includes a warning lamp 14, which is fixedly connected to the right front side of the support frame 1. It also includes a storage box 15, which is fixedly connected to the left front side of the support frame 1. Finally, it includes a toolbox 16, which is fixedly connected to the left side of the support frame 1.

[0018] The operator turns on the power to the screening device. The springs 2 at the four corners of the top of the support frame 1 provide elastic support for the screening machine 3, ensuring stable operation. The screen 4 inside the screening machine 3 begins to vibrate horizontally, performing preliminary screening of the iron filings poured in. Under the vibration of the screen 4, the iron filings are graded and screened, with larger iron filings remaining above the screen 4 and smaller iron filings passing through and falling down. At the same time, the cylinders 5 on the front and rear sides of the screening machine 3 start at preset times. The piston rod of the cylinder 5 moves the telescopic belt 9, causing the fixed block 6 to move. The elastic brush 8 at the bottom of the fixed block 6 brushes back and forth against the surface of the screen 4, brushing off the iron filings stuck in the gaps of the screen 4. The telescopic belt 9, arranged around the cylinder 5, expands and contracts synchronously with the movement of the cylinder 5, preventing iron filings from entering the moving area of ​​the cylinder 5. When the risk of clogging of the screen 4 is high, the operator can manually activate the nozzles 12 on the mounting plate 10. The four nozzles 12 spray high-pressure gas onto the surface of the screen 4, working in conjunction with the mechanical cleaning of the elastic brush 8 to achieve double cleaning of the screen 4 and thoroughly remove adhering iron filings. During the screening process, the top left-side lighting 13 provides ample illumination for the operator to observe the screening process. If the equipment experiences abnormal vibration, motor overload, or severe clogging of the screen 4, the warning light 14 on the front right side of the support frame 1 will automatically illuminate, reminding the operator to stop the machine and inspect it. The qualified iron filings after screening fall into the storage box 15 below. Once the storage box 15 is full, the operator can collect and recycle them. In daily use, if equipment maintenance is required, maintenance tools and accessories can be directly retrieved from the toolbox 16 on the left side of the support frame 1 for quick maintenance.
