Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, in particular to a ball mill for processing castings. Background Art

[0002] With the global energy crisis and increasing environmental protection requirements, energy-saving generators and generator sets, as well as energy-saving motors, are becoming increasingly widespread in both industrial and residential applications. Core components of these devices, such as motor stators, often utilize a combination of high-permeability silicon steel sheets and copper wire to reduce energy consumption and heat loss. However, in the casting processing and scrap recycling stages, traditional ball mills present significant technical bottlenecks in processing scrap from energy-saving motor stators.

[0003] Traditional ball mills utilize a fixed grinding zone design, making it difficult to achieve differentiated crushing of composite scrap materials consisting of silicon steel sheets (brittle) and copper wire (tough). This often results in over-crushing of the silicon steel sheets or breakage of the copper wire, necessitating multiple regrinding cycles. Energy consumption is 30%-40% higher than energy-saving standards. Furthermore, the power system lacks an integrated design, with independent motors driving components such as feeding, stirring, and filtering, further exacerbating energy consumption. The silicon steel sheets and copper wire in energy-saving motor stators require efficient separation for resource reuse, but traditional equipment relies on a single screening structure, unable to precisely control the crushed particle size. This results in copper wire integrity rates of less than 70%, and silicon steel powder purity below 95%, severely impacting the quality of recycled materials. Furthermore, dust emissions are a significant issue, with emission concentrations often exceeding 50mg / m³, which does not meet environmental standards. Existing equipment lacks real-time detection and dynamic adjustment mechanisms, requiring manual monitoring of grinding status and cleaning of filter components. This not only increases labor intensity but also leads to frequent equipment failures due to untimely maintenance. Taking the electrostatic dust collector as an example, the traditional design has a blockage frequency of 2-3 times per shift, requiring shutdown for manual cleaning, and reducing equipment utilization by more than 25%. To this end, we proposed a ball mill for casting processing. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a ball mill for casting processing, which has the following beneficial effects: 1. Through the linkage between the degreasing agent tank and the first solenoid valve spray head, the casting surface oil stains are automatically cleaned, and the material is lubricated to reduce grinding resistance. The vibrating sweeper cooperates with the auger plate to avoid waste blockage and accelerate transportation, thereby improving grinding efficiency. The adjustment component drives the mounting plate to move horizontally through the second motor, and the movement trajectory of the steel ball is changed in combination with the connecting rod mechanism to achieve differentiated crushing of silicon steel sheets and copper wires. The particle size uniformity of silicon steel sheets reaches ±0.2mm, and the integrity rate of copper wire exceeds 90%, solving the problems of "over-crushing" and "incomplete separation" in traditional ball mills. The gradual aperture of the discharge sleeve slides with the feed pipe, so that the silicone oil injection volume is automatically adjusted according to the grinding area, reducing the waste of lubricating medium while reducing the wear rate of steel balls and cavity by more than 25%.

[0016] 2. The docking baffle is driven to open by an electric telescopic rod, and the wire mesh and the first filter plate form a two-stage screening. Larger fragments are retained and powder particles fall to the electrostatic dust collection net. The unloading efficiency is increased by 50% compared with traditional inclined unloading, and metal loss caused by manual intervention is avoided. The cleaning brush revolves and slides back and forth driven by the L-shaped pull rod, and the vibration of the arc-shaped protrusion removes the accumulated particles on the surface of the electrostatic dust collection net in real time, reducing the mesh blockage rate to less than 5% and maintaining the dust collection efficiency above 98%. The industrial camera is linked with the particle detector to dynamically detect the size of the broken particles and the dust concentration. The current of the electrostatic dust collection net is automatically adjusted through the PLC system to make the metal powder recovery purity reach 99.2% while avoiding excessive dust emissions.

[0017] 3. The first motor drives multiple components simultaneously through bevel gears and chains, including feeding, degreasing agent stirring, and filtering and cleaning. This reduces the need for independent motors and reduces overall energy consumption by 20%-25% compared to traditional equipment. Key drive shafts, such as the third shaft, are made of wear-resistant alloy. When the annular searchlight rotates, a scraper simultaneously cleans dust from the industrial camera lens and mesh, eliminating the need for manual maintenance at heights. The automated feedback of the measuring components ensures a 90% accuracy rate for equipment fault warnings, extending maintenance cycles by three times. The electrostatic dust collection net combined with a sealed collection box achieves a dust emission concentration of ≤10mg / m³, meeting environmental standards. The silicone oil and degreasing agent recycling system reduces liquid medium consumption by 40%, reducing industrial waste liquid treatment costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Working principle: When in use, the motor stator is inserted into the material input pipe of the ball mill chamber 6. The first motor 5 is started, and its output shaft drives the first bevel gear 7118 to rotate through the second bevel gear 7119, thereby driving the first rotating shaft 712 to rotate. The first rotating shaft 712 engages with the first chain 717 through the outer first spur gear 713, driving the second spur gear 718 to rotate. The second spur gear 718 drives the stirring rod 719 to stir the aqueous degreaser in the degreaser tank 7110. The stirred degreaser is transported to the hollow annular plate 7111 through a pipeline and sprayed into the material input pipe through the multiple first solenoid valve spray heads 7112. It mixes with the stator to remove surface oil and lubricate, improving subsequent crushing efficiency. At the same time, the first spur gear 713 drives the fixed plate 714 to rotate, causing the four sets of vibrating sweeping rods 715 to rotate synchronously. The vibration prevents the stator from clogging at the joint of the auger plate 716 and accelerates the stator's descent into the buffer tank 711. Then, the ball mill chamber 6 drives the buffer tank 711 to rotate, starting the grinding and crushing process; The silicone oil in the silicone oil tank 7113 flows into the buffer sleeve 7114 through the pipeline, starting the second motor 7212, and its output shaft drives the third spur gear 7213 to rotate along the tooth groove outside the first rotating shaft 712, driving the mounting plate 721 to move horizontally along the inner wall of the buffer tank 711, thereby adjusting the working area of ​​the steel ball. When the mounting plate 721 moves, the feed pipe 7116 is pulled to slide by the T-shaped solenoid valve spray head fixed at the rear end, stretching the first spring 7117, so that the feed port of the feed pipe 7116 and the aperture of the discharge sleeve 7115 are gradually aligned from front to back. When the mounting plate 721 moves forward, the working range of the steel ball is reduced, and the silicone oil discharge of the feed pipe 7116 is reduced synchronously, realizing the linkage control of the flow rate and the grinding area; When the mounting plate 721 moves forward, it is guided by the arc-shaped sliding grooves of the slider 722 and the rotating plate 723, driving the first connecting rod 724 to pull the docking baffle 725 to rotate. The docking baffle 725 is linked with the second connecting rod 728 and the third connecting rod 729, so that the motion trajectory of the steel ball is transformed from a parabola to a track-changing impact. The third connecting rod 729 is constrained by the limiting sleeve 7210 to adjust the impact angle and specifically crush the silicon steel sheet and the copper wire. The limiting sleeve 7210 is fixed on the outer side of the first rotating shaft 712, and the sliding rod on its inner wall provides a guide for the third connecting rod 729. At the same time, it limits the maximum movement range of the third connecting rod 729 to avoid the docking baffle 725 from deflecting too much, which causes the steel ball impact energy to be concentrated in a local area, resulting in a decrease in grinding efficiency or cavity wear. By limiting the sliding stroke of the third connecting rod 729, it is ensured that the corresponding relationship between the deflection angle of the docking baffle 725 and the steel ball trajectory is accurately controllable. For example, the deflection angle is 15°-20° when the silicon steel sheet is crushed, and the deflection angle is 5°-10° when the copper wire is separated. After the casting is crushed, the electric telescopic rod 727 is activated. Its output shaft rotates the rotating plate 723 via the push block 726, causing the five sets of docking baffles 725 to open synchronously around the mounting plate 721, revealing the woven wire mesh inside. Subsequently, the hydraulic cylinder 3 lifts and deflects the first bracket 2, filtering the stator fragments through the woven wire mesh. Larger particles are retained on the first filter plate 7120, while the powdered particles fall to the electrostatic dust collection net 812 in the collection box 811. When the first motor 5 drives the second bevel gear 7119 to rotate, the third rotating shaft 816 is driven to rotate through the fourth bevel gear 817, thereby causing the L-shaped pull rod 818 to drive the cleaning brush 819 to revolve. The L-shaped pull rod 818 is acted upon by the arc-shaped protrusion of the annular rotating plate 8110, and produces reciprocating sliding during rotation, causing the cleaning brush 819 to clean the woven wire mesh inside the sliding baffle 7211. The vibration generated by the cooperation of the second spring 8111 and the L-shaped pull rod 818 accelerates the copper particles to fall into the collection box 811. The third rotating shaft 816 drives the first gear plate 814 through the third bevel gear 815, which in turn drives the second rotating shaft 813, rotating the fixed frame 821. The industrial camera 8211 rotates synchronously with the annular searchlight 8212 to detect mesh blockage and metal particle size in the electrostatic dust collector 812. The third motor 824 is activated, and its output shaft drives the fifth spur gear 828 through the fourth spur gear 825 and the second chain 827, causing the mounting block 823 to translate along the threaded rod 822. The particle detector 826 simultaneously scans the dust concentration and provides feedback to the control system to adjust the current of the electrostatic dust collector 812. The second gear plate 829 drives the annular searchlight 8212 through the sixth spur gear 8210. As the annular searchlight 8212 rotates, the scraper 8213 uses centrifugal force to clean dust and mesh blockage from the lens, ensuring detection accuracy.
