Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material recovery and separation equipment, in particular to a specific gravity sorting system. Background Art
[0002] With the vigorous promotion of electric vehicles, a large number of batteries will face the problem of being scrapped in the future. The recycling rate of discarded batteries is relatively low. A large number of discarded batteries have caused waste of resources and energy and environmental pollution. At the same time, a large amount of valuable metal resources in the batteries, such as copper, aluminum, nickel and cobalt, have been greatly wasted. Rough or improper recycling of waste batteries will also cause great waste of resources and environmental pollution.
[0003] Therefore, the existing battery recycling is to crush the batteries and then use filtering and sorting processes to sort out the internal metal resources and electrode materials, so as to recover a large amount of valuable metal resources such as copper, aluminum, nickel and cobalt in batteries. The most commonly used machine for sorting is the gravity separator. During the gravity sorting, the material after the plastic is sorted out after crushing is introduced along the feed port of the gravity separator, and the crushed material is sorted for copper and aluminum after the fan is turned on.
[0004] There are still certain problems in the above-mentioned existing technology: the feeding process cannot be uniform and continuous, and in the process of separating two materials with different specific gravities, a single separation can only separate 20-30% of the mixed materials from the high-specific gravity material outlet and the low-specific gravity material outlet on both sides. The remaining 70%-80% of the materials cannot be directly sorted for the second time. The remaining mixed materials need to be manually accumulated for a period of time before manual secondary loading. This sorting method is discontinuous and the recovery efficiency is low. Utility Model Content
[0005] The utility model aims to solve the problems in the prior art and provides a specific gravity sorting system capable of continuous cyclic sorting, which solves the problems in the prior art of requiring manual sorting and secondary loading of mixed materials, resulting in inability to continuously sort and low sorting efficiency.
[0006] The technical solutions adopted in this utility model are as follows:
[0007] A specific gravity sorting system includes a specific gravity sorting mechanism, wherein the specific gravity sorting mechanism is provided with a first discharge port and a second discharge port, a mixed discharge port is provided between the first discharge port and the second discharge port, and the specific gravity sorting system further includes a transfer mechanism and a circulation mechanism, wherein the loading portion of the transfer mechanism is connected to the mixed discharge port, the unloading portion of the transfer mechanism is connected to one end of the circulation mechanism, and the other end of the circulation mechanism is connected to the loading portion of the specific gravity sorting mechanism. By providing the transfer mechanism and the circulation mechanism in the sorting system, two materials that are still mixed after a single sorting can be re-loaded to the specific gravity sorting mechanism, without the need for manual waiting for accumulation for a period of time before manually loading, continuous loading and sorting of mixed materials can be achieved, thereby improving sorting efficiency.
[0008] Preferably, the circulation mechanism includes a lifting unit and a circulation pipe, the unloading part of the transfer mechanism is connected to the lower end of the lifting unit, the upper end of the lifting unit is connected to one end of the circulation pipe, and the other end of the circulation pipe is connected to the loading part of the specific gravity sorting mechanism.
[0009] Preferably, the loading portion of the gravity sorting mechanism is provided with a first feed port and a second feed port, the first feed port being connected to a feed pipe, and the second feed port being connected to a circulation pipe. By providing two feed ports on the loading portion of the gravity sorting mechanism, during multiple feeding processes, the material fed through the first feed port will not affect the mixed material circulating in the second feed port.
[0010] Preferably, the specific gravity sorting mechanism is provided with a vibrating plate, a first vibrating motor, and a fan. The first vibrating motor is connected to the vibrating plate, and the vibrating plate is arranged at an angle. A bulking plate is also provided within the feeding portion of the specific gravity sorting mechanism. The bulking plate is arranged below the first and second feed ports and above the vibrating plate, and the bulking plate is arranged at an angle. The bulking plate allows for preliminary bulking of the mixed material before it is added to the vibrating plate, thereby improving the subsequent vibration and sorting effects on the vibrating plate.
[0011] Preferably, the bulk material plate is provided with a plurality of guide plates, each guide plate being formed by joining two inclined plates. The guide plates can separate the mixed material falling from the first feed port or the second feed port when sliding on the bulk material plate, thereby improving the dispersion effect of the bulk material plate.
[0012] Preferably, the transfer mechanism includes a blanking plate and a transfer trough. The blanking plate is arranged at an angle, one end of the blanking plate is connected to the mixed material outlet, and the other end of the blanking plate is arranged above the transfer trough. One end of the transfer trough is connected to the circulation mechanism. The transfer trough is arranged at an angle, and the end of the transfer trough near the blanking plate is higher than the end of the transfer trough near the circulation mechanism. The arrangement of the blanking plate and the transfer trough can realize automatic transfer of the mixed material under the action of gravity.
[0013] Preferably, a second vibration motor is installed on the transfer trough. By setting the second vibration motor, the transfer effect of the material on the transfer trough can be improved, and the problems of material accumulation and slow transfer speed can be avoided.
[0014] Preferably, the lifting unit is a vertical screw conveyor or a bucket elevator.
[0015] Preferably, the lifting unit includes a base, a temporary storage box is provided on the base, a first opening is provided on one side of the temporary storage box, the first opening is used to connect with the transfer mechanism, a vertical screw conveyor or bucket elevator is provided on the temporary storage box, the feed port of the vertical screw conveyor or bucket elevator is connected to the temporary storage box, and the second opening on the upper part of the vertical screw conveyor or bucket elevator is connected to the circulation pipe.
[0016] The advantages of the present invention are as follows: The transfer mechanism and circulation mechanism provided within the sorting system allow two materials that remain mixed after a single sorting operation to be re-fed to the gravity sorting mechanism, eliminating the need for manual re-fed loading after a certain period of time. This allows for continuous loading and sorting of the mixed materials, thereby improving sorting efficiency. The two feed ports provided within the gravity sorting mechanism ensure that, during multiple feeding operations, materials fed into the first feed port do not affect the mixed materials circulating in the second feed port. The bulking plate allows for preliminary bulking of the mixed materials before feeding them onto the vibrating plate, thereby improving the subsequent vibration and sorting effects on the vibrating plate. The guide plate allows for separation of the mixed materials that fall from the first or second feed ports as they slide on the bulking plate, thereby enhancing the dispersing effect of the bulking plate. The discharge plate and transfer chute enable automatic gravity-driven transfer of the mixed materials. The second vibrating motor improves the transfer efficiency of the materials on the transfer chute, preventing material accumulation and slow transfer speeds. The vertical screw conveyor has a relatively simple structure, occupies a small area and has a low cost. At the same time, the vertical screw conveyor has a better sealing effect, which reduces the problem of more impurities in the material when transporting and lifting mixed materials multiple times.

[0027] In this embodiment, the circulation mechanism includes a lifting unit and a circulation pipe 4. The unloading part of the transfer mechanism is connected to the lower end of the lifting unit, the upper end of the lifting unit is connected to one end of the circulation pipe 4, and the other end of the circulation pipe 4 is connected to the loading part of the specific gravity sorting mechanism.
