Description
Technical Field
[0001] The utility model relates to the technical field of cleaning and drying devices, in particular to a high-efficiency cleaning and drying device for magnetic materials. Background Art
[0002] With the wide application of magnetic materials in fields such as motors, electronic components, and new energy devices, the cleaning and drying processes in their production become key links affecting material performance and manufacturing costs; traditional cleaning processes mostly rely on high-pressure flushing. Although comprehensive cleaning can be achieved, it is easy to cause damage to the surface or internal structure of the magnet due to improper pressure control. At the same time, the one-time use of cleaning liquid results in high costs.
[0003] The Chinese utility model patent with the publication number CN213887403U discloses a hard magnetic centralized ultrasonic cleaning and drying machine, including an outer frame of the machine rack. A vibrating feeding funnel is arranged above the right side of the outer frame of the machine rack. A pre-cleaning ultrasonic vibrating plate is arranged below the vibrating feeding funnel. A transmission system inside the tank is arranged below the pre-cleaning ultrasonic vibrating plate. A cleaning circulation pump is fixedly connected to the right side of the outer frame of the machine rack.

The transmission system inside the tank includes a conveying track, and an ultrasonic cleaning tank is arranged below the conveying track; however, this device does not set up a filtering system, and dirt and impurities in the recycled cleaning liquid cannot be effectively separated.

In addition, its flushing pressure is fixed and cannot be dynamically adjusted according to the magnetic permeability and pollution degree of different magnetic materials, and there is still a problem that the magnetic material is damaged due to too high pressure, resulting in difficulty in improving the yield rate.

[0025] Magnetic material cleaning and drying process: The magnetic material 11 is fed into the equipment by the feeding channel device 3. The height of the pressing plate 35 is adjusted through the cooperation of the height adjusting plate 33 and the pressing plate 35 to adapt to materials of different heights, ensuring stable fitting during the conveying process.

The high-pressure nozzle 72 sprays the cleaning liquid on the magnetic material 11 through the cleaning tank 36. The cleaning liquid flows into the water collection tank 62 through the through groove 61, and then enters the first filtration assembly 82 through the water collection pipe 81, successively passing through the first filter screen 826, the magnetic filter screen 822 and the magnetic filter tank 84. The filtered clean cleaning liquid is circulated back to the high-pressure nozzle 72 by the high-pressure water pump 85 to form a water circulation system. Part of the splashed cleaning liquid is recovered to the filter tank 821 by the water collection tray 87 and the small water collection pipe 86 to reduce waste. The cleaned magnetic material 11 is initially blown to remove surface moisture by the small air knife 91, and then enters the conveyor belt 4 and is sent to the large air knife 92 for secondary air blowing to remove water. The pressing device 93 prevents the magnetic material 11 from being blown off by the large air knife 92. Finally, the magnetic material 11 enters the hot air box 44 and is evenly dried by the hot air generated by the first fan 42 and the hot air heater 43 to ensure that there is no residual water stain on the surface.

The large air knife and the material pressing device are both arranged above the conveyor belt, and the large air knife is located in the middle of the material pressing device. The material pressing device is used to prevent the magnetic materials from being blown off the conveyor belt by the large air knife. A second support is fixed on the base. The large air knife is fixed on the second support. A second fan is fixed inside the base. The second fan provides air source for the large air knife. The large air knife is used to perform further blowing and water removing on the magnetic materials after cleaning.
10. The highly efficient cleaning and drying equipment for magnetic materials according to claim 9, characterized in that, The blank holding device includes a blank holding belt, a first pulley, a second pulley, a third pulley and a fourth pulley. A third bracket is fixed on the base. The first pulley and the second pulley are fixed above the conveyor belt through the third bracket. The third pulley and the fourth pulley are fixed in the hood. A first motor is fixed in the hood. A gear is fixed on the output shaft of the first motor. The first motor drives the fourth pulley to rotate through gear meshing. The four ends of the blank holding belt are respectively matched with the first pulley, the second pulley, the third pulley and the fourth pulley. The blank holding belt between the first pulley and the second pulley is located above the conveyor belt and below the large air knife. The blank holding belt between the first pulley and the second pulley is attached to the upper surface of the magnetic material.
