Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of recycling devices, in particular to a neodymium iron boron waste quantitative batch taking-out device. BACKGROUND

[0002] Neodymium iron boron waste refers to waste containing neodymium, iron and boron elements, usually from waste electronic products, magnets, motors and other materials containing magnetic materials. Because neodymium iron boron material has high magnetism and high energy density, it is widely used in high-tech fields such as electric vehicles, computers, mobile phones and other products, and waste neodymium iron boron material can obtain valuable elements such as neodymium, iron and boron through recycling and reprocessing, reducing resource waste and environmental pollution.

[0003] In the recycling process of neodymium iron boron waste, manual magnetic sorting is a common method for recycling neodymium iron boron waste. This method requires a large amount of manpower and has high labor costs. At the same time, due to human factors, errors can easily occur during the sorting process, such as missed sorting and misjudgment of material properties, which makes it difficult to meet large-scale recycling needs. If sorting is not performed, these valuable metals cannot be recycled and utilized, resulting in resource waste.

[0004] The current device still has many inconveniences during use or work;

[0005] The specific defects are as follows:

[0006] ①Firstly, according to the magnetic sorting of neodymium iron boron waste, different ways of processing are needed for different magnetic waste for different material processing. Although modern technology can achieve partial automation of magnetic sorting, for complex waste, human labor is still needed for assistance, so full automation cannot be achieved. When manually sorting neodymium iron boron waste, a magnet is used to attract neodymium iron boron waste one by one. When encountering heavy neodymium iron boron waste, it needs to be moved with great force, which consumes a lot of physical strength and cannot automatically separate, which greatly affects the work efficiency of sorting.

[0007] ②Secondly, after sorting neodymium iron boron waste, chemical smelting is needed. Because the capacity of the smelting furnace is fixed, it needs to be manually weighed in equal amounts. However, neodymium iron boron waste is heavy, and manual weighing is laborious, requiring a large amount of labor input and wasting resources.

[0020] (Three) beneficial effects

[0021] Compared with the prior art, the present application provides a neodymium iron boron waste quantitative batch taking-out device, which has the following beneficial effects:

[0022] 1. By cooperating the structure of the suction assembly and the structure of the feeding device, the suction hammer rotates, the magnetic neodymium iron boron waste on the suction conveying belt is moved to the separation channel, and after the suction hammer rotates and separates from the arc-shaped slide rail, the magnetic neodymium iron boron waste slides along the separation channel and falls into the quantitative hopper, thereby achieving the effects of automatically attracting the magnetic neodymium iron boron waste, automatically separating the suction hammer from the magnetic neodymium iron boron waste, separating the magnetic neodymium iron boron waste from the mixed neodymium iron boron waste, and automatically collecting the magnetic neodymium iron boron waste in the quantitative hopper. The suction assembly continuously operates to greatly improve the sorting efficiency, and the suction hammer is always not in direct contact with the neodymium iron boron waste, thereby avoiding the condition that the neodymium iron boron waste is difficult to separate from the surface of the suction hammer, and achieving the effects of automatic attraction and automatic separation.

[0023] 2. By cooperating the structure of the quantitative device and the structure of the feeding device, the magnetic neodymium iron boron waste is accumulated in the quantitative hopper, the quantitative hopper slides downward along the pouring chute, the quantitative hopper turns at the turning position of the pouring chute, the magnetic neodymium iron boron waste is poured, the mass of the quantitative hopper is reduced after the non-magnetic neodymium iron boron waste is removed, the spring sheet pulls the conveying rope, the conveying rope pulls the quantitative hopper to move upward along the pouring chute to the original position, and the magnetic neodymium iron boron waste is continuously collected, thereby achieving the effect of quantitative collection of the magnetic neodymium iron boron waste, replacing the weighing function, and realizing the effect of batch pouring of the magnetic neodymium iron boron waste. The weighing function is completely replaced by the machine, the labor consumption of manual weighing is reduced, the time for manual sorting is reduced, and the work efficiency is improved.

[0024] 3. By using the quantitative device structure in conjunction with the feeding device structure, when the quantitative hopper reaches the turning point of the tilting trough, the protrusion on the steering rod is locked in the limiting groove. The quantitative hopper turns, causing the steering rod to rotate and slide clockwise in the steering groove, causing the baffle plate to rotate clockwise and block the discharge port of the separation channel. When the quantitative hopper pours out a quantitative amount of magnetic NdFeB waste, the separation channel stops discharging. After the quantitative hopper rotates and rises, it drives the baffle plate to rotate counterclockwise, opening the discharge port of the separation channel, allowing the magnetic NdFeB waste that has fallen into the separation channel to slide into the quantitative hopper. This achieves the effect of quantitatively and batch-wise pouring of magnetic NdFeB waste while allowing the attraction component to continuously sort the NdFeB waste, avoiding the waste from continuing to enter the quantitative hopper during the feeding process, which would cause deviations in the feeding amount and affect the accuracy of batch feeding.

[0025] 4. The metering device is used manually. The metering handle is pushed forward by hand. The deeper the metering handle is pushed, the more NdFeB waste is poured into the metering hopper in batches. The metering handle is pulled backward. The further the metering handle is pulled, the less NdFeB waste is poured into the separation channel in batches. This achieves the result of adjusting the fixed amount of NdFeB waste in batches, effectively addressing the different quality requirements of different batches of NdFeB waste and meeting the recycling and processing needs of different waste materials.
