Description

Technical Field

[0001] This utility model relates to the field of crushing and screening technology, and in particular to an integrated device for crushing and screening iron oxide scale. Background Technology

[0002] Iron oxide scale, a product of steel production, is rich in iron and has high recycling value. It can be used as an iron-containing auxiliary material in blast furnace ironmaking and in powder metallurgy. However, virgin iron oxide scale is often uneven in size and contains impurities, which can negatively impact subsequent production if recycled directly. Therefore, it needs to be crushed and screened to obtain materials with uniform particle size and fewer impurities, meeting the needs of different recycling scenarios.

[0003] The screens in existing integrated iron oxide scale crushing and screening devices are mostly "fixed" or require disassembly of the main device for cleaning and replacement. The operation process is complicated, requiring a lot of manpower and time, which seriously reduces maintenance efficiency. At the same time, the vibration generated during the screening process is directly transmitted to the screen. The screen is subjected to rigid vibration for a long time, which makes it prone to deformation and breakage. This not only shortens its own service life, but also leads to poor particle size uniformity of the screened material, affecting the quality of recycling. Utility Model Content

[0031] Working principle: Iron oxide scale enters through the feed hopper 4, and then passes through the inclined plate 7 into the trapezoidal cover 3. The first motor 8 is then started, and its output drives one of the rotating columns 5 to rotate. Since the rotating gears 9 at the ends of the two rotating columns 5 mesh with each other, the two rotating columns 5 rotate synchronously in opposite directions, and the crushing rollers 6 on the surface crush the iron oxide scale. After the crushed material falls into the machine body 1, the second motor 29 starts, driving the rotating rod 27 to rotate. The cam 28 on the rotating rod 27 rotates with the rotating rod 27, continuously pushing the push plate 26 up and down, which in turn drives the lifting plate 15 to slide along the inner wall of the square hole 14 and the sliding plate 31 within the limiting plate 30, thereby reducing vibration and buffering the impact of the screen plate 20 during the screening process. When it is necessary to clean or replace the screen plate 20, remove the U-shaped mounting plate 23, hold the handle 32, and the screen plate 20 can be directly pulled out from the convex groove 18 of the fixing plate 16 and the connecting plate 17 and the recessed hole 19 of the lifting plate 15. After cleaning or replacement, reinsert the new screen plate 20 into the convex groove 18 and the recessed hole 19, and install the U-shaped mounting plate 23 to fix the screen plate 20. The device can then resume stable operation.

[0032] The wiring diagrams of the first motor 8 and the second motor 29 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring arrangement of the first motor 8 and the second motor 29 will not be explained in detail.
