Description

[Detailed Description of the Invention] Industrial Application Field The present invention collects a large amount of used waste dry batteries, sorts them according to shape and type, and then disassembles the dry batteries into their component parts by mechanical processing and collects them. The present invention relates to a device for recycling.

BACKGROUND OF THE INVENTION With the increase in the number of portable electrical appliances, the consumption of dry batteries is rapidly increasing, and recently, alkaline dry batteries, which have a long life and are suitable for continuous use, have been increasing at a rate that exceeds conventional manganese dry batteries. However, dry batteries contain a small amount of mercury, and the amount of mercury used to manufacture dry batteries per year is 1.
It is said to reach 0.7 tons. Until now, used batteries have been collected in general trash cans or special containers, and then landfilled or incinerated, but if today's mass consumption continues It is clear from experience that large amounts of hazardous substances leak from the ground and incineration plants, causing harm to the human body. Therefore, there is an urgent need for a processing method for collecting a large amount of used waste dry batteries and rendering them harmless. Additionally, in order to conserve resources, it is desirable to recycle collected waste batteries as much as possible.

In the past, many methods have been proposed for treating waste containing hazardous substances such as mercury, cadmium, arsenic, lead, and chromium using heavy metal adsorbents, but the target has been limited to dry batteries for detoxification and recycling. There were few known methods or devices for doing this.

The present inventor focused on the above-mentioned points and filed a patent application No. 58-242161 entitled "Method for sorting and collecting waste dry batteries" for a new method for processing waste dry batteries. has been improved and proposed as the present invention.

Therefore, an object of the present invention is to provide a processing device that can recycle dry batteries by subjecting them to mechanical processing, disassembling them into component parts, and recovering them.

Means for Solving the Problems and Their Effects The above-mentioned object of the present invention is to provide a die made of a hard material that receives the bottom part of one pole side of a cylindrical dry battery, and a die that is press-fitted into the top surface of the other pole side of the cylindrical dry battery. a cylindrical push-in fitting, and an insulating cylinder cutting means disposed adjacent to the die; The second dimension of the jacket corresponds to the inner diameter of
The inner diameter portion is formed in a stepped shape, and at least one pair of the insulating cylinder cutting means are arranged symmetrically to face each other in the diametrical direction of the die, and the opposing cutting means are configured to cut the insulating cylinder of a cylindrical dry battery. This is achieved by a dry battery cutting, separating and processing device characterized by being positioned.

Based on this configuration, the cylindrical dry battery is compressed between the pusher and the die, the jacket is caught on the stepped part of the die and separated, and the insulating cylinder is cut by the cutting means and separated into halves. do. The zinc can in the center of the battery falls down and is sent to the next disassembly process. The insulating ring and metal bottom fall downward and are collected.

Preferably, the hard material is, for example, steel, sintered alloy, ceramic, or the like.

As the cutting means, a cutting blade, a grinder, a water jet, a heating coil, a laser, etc. can be used.

Other characteristics and advantages of the invention will become apparent from the following description with reference to the embodiments of the accompanying drawings.

Embodiment FIG. 1 shows a state in which a cylindrical manganese dry battery 30 is housed in a cutting and separating processing apparatus according to the present invention.
, a cylindrical push-in fitting 14 that is press-fitted into the upper surface of the positive electrode side of the dry cell battery, and an insulating cylindrical cutting blade 16 that is disposed adjacent to the die 12 . In the structure shown in FIG. 1, the die 12 is fitted into the stepped part of the pedestal 18, and a reinforcing tube 20 is further provided on the pedestal 18, but depending on the degree of mass production, these can be integrally formed. It is also possible to do so.

The die 12 can also be made of hard materials other than steel, such as corrosion- and wear-resistant sintered alloys or ceramics. The die 12 is formed in a stepped manner with a first inner diameter part 21 having dimensions corresponding to the outer diameter of the jacket 32 of the dry battery and a second inner diameter part 22 having dimensions corresponding to the inner diameter of the jacket 32 (Fig. 4). , see Figures 5 and '6).

As shown in FIG. 2, a pair of insulating cylinder cutting blades 16 are arranged symmetrically to face each other in the diametrical direction of the die 12, and are inserted into a slit provided in the pedestal 18. The distance P between the opposing cutting blades is set to a dimension that cuts the insulating cylinder 34 of the dry battery. Positioning is performed in the same manner when other cutting means are used.

The outer diameter of the push-in fitting 14 is made approximately equal to the inner diameter of the opening of the jacket 32 of the dry battery, and a hollow portion 24 is formed in the bottom surface of the push-in fitting 14 to accommodate the positive terminal of the dry cell battery.

Although FIG. 3 is a manufacturing drawing of the pedestal 18, the dimensions shown are merely an example. Figures 4, 5, and 6 show the common pedestal 1.
8 is a manufacturing drawing for manufacturing dies for AA batteries, AA batteries, and AA batteries, respectively. Cylindrical dry batteries other than these can also be manufactured in the same manner.

In the case of a steel die, the material is, for example, 5K2 (carbon tool steel), which is heat-treated by quenching and tempering to have a rating of RC63 or higher.

Based on this configuration, the cutting and separating processing apparatus of the present invention operates as shown in FIGS. 7 to 9.

First, as shown in FIG. 7, when the dry battery 30 is put into the reinforcing tube 20 with its negative electrode side facing down, the bottom of the negative electrode side is inserted into the die 1.
20 It gets caught on the stepped part and stops.

Subsequently, as shown in FIG. 8, when the push-in fitting 14 is lowered, the dry cell jacket 32 is left behind while being caught on the stepped part of the die, and the insulating tube 34 and the zinc can 36 (
(see Figure 1) are pushed downward as they are. When the insulating tube 34 passes through the cutting blade 16, the opposing position is cut in the vertical direction.

As the push-in fitting 14 is further lowered, as shown in FIG. It falls in a separated state.

Each separated part is collected and sent to the next recycling process.

Cylindrical alkaline batteries can also be cut and separated using the same processing method.
