Abstract

PURPOSE:To attain the re-utilization of resources and the prevention of public nuisance, by continuously separating a mechanically crushed waste dry battery into a component subjected to waste disposal and a component re-utilized as material resources and sorting re-utilizable material resources by material. CONSTITUTION:Waste dry batteries are crushed and ground by a crusher 4 while the crushed and ground dry batteries are allowed to pass through a magnetic separator 6 through a chute 5 to sort a magnetic material which is recovered in a metal storage vat 9 by a conveyor 7 and a chute 8. A non-magnetic material is supplied to a classifier 11 through a chute 10 and a part of lumpy and powdery nonferrous metals is sent to a mesh conveyor 12 and nonferrous lumps are washed by recirculated water from piping 19 to be recovered in a nonferrous metal storage vat 13. The other nonferrous metal powder is introduced into a second precipitation tank 16 and recovered by precipitation. The greater part of the nonferrous metal powder and plastic or the like enters a first precipitation tank 15, and a floated substance and a precipitated substance are classified to be respectively recovered.

Description

[Detailed Description of the Invention] Disposal of waste dry batteries is a particular problem in each local government when it comes to waste disposal.The production of dry batteries is rapidly increasing year by year due to the direction of electronics equipment, and as a result, the number of waste dry batteries is also increasing. As more and more waste is collected, if it is mishandled, pollution problems will occur. Therefore, this solution has been considered urgent.

The present invention proposes one of these solutions,
This is a reuse of resources that can be collected from waste dry batteries, and it also prevents pollution from occurring. In this sense, the present invention can exhibit great advantages in production applications as a technology for processing waste dry batteries.

In carrying out the present invention, depending on the type of waste dry battery, it may be necessary to change the chemical aqueous solution or change the passage time etc. upon separation.

Figure 1 shows an example of an elevation view of the device for explanation. (1) is a storage hopper for waste dry batteries and a hopper for supplying waste dry batteries, and (2) is a capacity feeder for discarding waste batteries. Supply a certain number of dry batteries to the chute (3). (4)
A crusher is used to crush and crush metals, non-ferrous metals, and non-metals into a certain size or into powder. The crushed and pulverized waste dry batteries pass through the chute in (5) and the magnetic separator in (6) to sort out magnetic substances (metals) and are transferred to the conveyor tray in 7).
The non-magnetic materials guided by the shoes 1 to (9) and collected in the metal storage vat (9) pass through the chute (10) and are passed through the classifier (11), where some of the non-ferrous metal lumps and powder are collected in the metal storage vat (9). The nonferrous metal lumps sent to the mesh conveyor (12) are washed with circulating water through the pipe (j9) and collected in the nonferrous metal storage vat (]3). For other non-ferrous metal powders, settle tank No. (16)
2, settle and collect. Also, most of the non-ferrous metal powder plastics, vinyl, etc. are guided through the overflow duct (14) and enter the sedimentation tank No. (15), where the plastics, vinyl, and paper float on the water surface. collect. Other non-ferrous metal powders that settle below the water surface are collected.

Put the medicinal solution into the classifier (11) (15) (16
) overflow into sedimentation tanks No. 1 and No. 2, and pass the medicinal aqueous solution through the piping of (7). The non-ferrous metal lump is washed and circulated to the classifier (11). In this way, the metal-containing chemical aqueous solution is not leaked to the outside, thereby preventing the occurrence of pollution. As described above, the present invention continuously recovers resources by material, thereby reducing rod costs and improving work efficiency.

Claims (1)

[Claims] Waste dry batteries are mechanically crushed, and the materials inside the batteries are continuously separated into those to be disposed of and those to be reused as resource materials, and the resource materials that can be recycled are separated by material. In addition, if these waste dry batteries are disposed of naturally or incinerated, they may contaminate water, soil, air, etc. and cause a pollution problem. Therefore, devices aimed at recycling resources and preventing the occurrence of pollution.
