Description

Technical Field

[0001] The utility model relates to the technical field of solid material recovery, in particular to a vibration magnetic separation device. Background Art

[0002] Waste lithium batteries contain numerous recyclable components, including valuable metals and organic matter. Safe and efficient recycling of lithium batteries is a key issue in sustainable resource utilization. Existing waste lithium battery recycling processes primarily involve crushing the batteries, followed by high-temperature pyrolysis, screening, and sorting to recover products such as black powder, copper, iron, and aluminum.

[0003] In the recycling process for used lithium batteries, the batteries are crushed and then subjected to high-temperature pyrolysis to produce pyrolysis particles. The black powder is then screened and separated to produce lithium battery metal particles. The main components of lithium battery metal particles are iron, copper, and aluminum. Iron particles are ferromagnetic, so magnetic separation is typically used to separate the iron from the lithium battery metal particles. This facilitates the recycling of this iron and facilitates the subsequent separation of copper and aluminum.

[0004] Magnetic separation devices typically transport lithium battery metal particles via a conveyor belt. A magnetic suction device is installed above a portion of the conveyor belt to absorb the magnetic material (i.e., iron particles) contained within the lithium battery metal particles, achieving magnetic separation. However, during transportation on the conveyor belt, the material accumulates, and some of the magnetic material is pressed beneath the lithium battery metal particles, making it difficult for the magnetic suction device to capture it. This results in incomplete magnetic separation and low efficiency. Furthermore, a small amount of black powder is mixed with the lithium battery metal particles, which cannot be recycled by conventional magnetic separation devices, resulting in a waste of resources. Utility Model Content

[0005] In order to solve the problems that part of the magnetic material is pressed underneath when the existing magnetic separation device magnetically separates lithium battery metal particles, the magnetic separation is incomplete and the magnetic separation efficiency is low; the magnetic separation device cannot recycle and utilize black powder, resulting in waste of resources, the utility model provides a vibrating magnetic separation device, which can evenly disperse and spread the material on the conveying plate, so that the magnetic material in the material can be separated more thoroughly during the magnetic separation process; it can prevent the dust from being dispersed in large quantities due to the vibration of the material conveying platform, and at the same time recycle and utilize the dust in the material separately, and is particularly suitable for magnetic separation of lithium battery metal particles in the lithium battery recycling process.

[0006] The technical solution of the utility model is:

[0007] A vibrating magnetic separation device includes a material conveying platform, characterized in that the material conveying platform is arranged at an angle, with the higher end being the feed end and the lower end being the discharge end; the bottom of the material conveying platform is connected to the frame via a spring, a vibrating motor is arranged below the material conveying platform, and a conveying plate is arranged on the material conveying platform; a magnetic suction frame is suspended above the material conveying platform, and a magnetic suction module is arranged at the bottom of the magnetic suction frame;

[0008] A dust hood is provided above the conveyor plate near the feed end. The dust hood does not overlap with the magnetic module in the vertical direction. A dust filter is provided at the bottom of the dust hood. The top of the dust hood is connected to the dust hopper through a dust removal pipe, and a negative pressure fan is provided on the dust removal pipe.

[0009] The magnetic suction module includes a magnetic material conveyor belt, a magnetic suction device is provided on the inner side of the magnetic material conveyor belt, a magnetic material trough is provided below the discharge end of the magnetic material conveyor belt, and the magnetic material trough is connected to the magnetic hopper.

[0010] Furthermore, the inclination angle of the material conveying platform is 1°-5°.

[0011] Furthermore, a feeding device is provided above the feeding end of the material conveying platform, and a non-magnetic material trough is provided below the discharging end of the material conveying platform, and the non-magnetic material trough is connected to the non-magnetic material hopper.

[0012] Furthermore, the conveying plate is a stainless steel plate.

[0013] Furthermore, the pore size of the dust filter is 150 μm.

[0014] Furthermore, the magnetic attraction device is a permanent magnet or an electromagnet.

[0015] Furthermore, baffles are provided on both sides of the conveying plate to prevent the material from spilling out during the vibration process.

[0016] Furthermore, a height adjustment device is provided on the magnetic frame to adjust the height of the magnetic module.

[0017] Furthermore, the material of the magnetic material conveyor belt is rubber.

[0018] The beneficial effects of the present invention are:

[0019] 1. The vibrating magnetic separation device provided by this utility model features a vibration motor installed beneath the material conveyor platform. As the conveyor platform transports materials, the vibration motor vibrates the entire conveyor platform, evenly dispersing the materials across the conveyor platform. This prevents material accumulation and magnetic material from being trapped and difficult to separate during magnetic separation. This allows for more thorough separation of magnetic material, improving magnetic separation efficiency.

[0020] 2. This utility model features a dust hood above the conveyor platform, near the feed end. A dust filter is installed at the bottom of the hood, and a dust duct connects the top of the hood to a dust hopper. A negative pressure fan is installed in the duct. As the conveyor platform transports materials, dust mixed with the material is drawn through the dust hood into the duct and then into the dust hopper. This prevents the material from being dispersed due to the vibration of the conveyor platform, while also facilitating the separate recycling of this dust.

[0021] 3. This utility model is particularly suitable for magnetically separating lithium battery metal particles in lithium battery recycling processes. When applied to this process, the lithium battery metal particles can be magnetically separated into iron particles and a mixed copper and aluminum particle size. Meanwhile, the remaining black powder in the lithium battery metal particles is separately recovered into a dust hopper. This effective magnetic separation facilitates the separate recycling of different components. BRIEF DESCRIPTION OF THE DRAWINGS
