[Prior art 1: Various types of dry batteries are mixed in municipal waste,
Even through separate collection, it is difficult to prevent batteries from getting mixed in. Therefore, for example, in the process of producing compost as an example of resource recovery, dry batteries are often destroyed by the crushing process or mechanical force during handling, and they are also exposed to various elements during the production process, causing corrosion. Due to destruction and corrosion of
Dry cell battery components (mercury, zinc, lead, cadmium, copper, and others) were exposed, which could lead to heavy metal contamination of the product compost.

In addition, if it falls into the non-shredded group and is disposed of in a landfill while still being contained in garbage, there is a problem of heavy metal sludge in the soil due to aging, and incineration may cause problems such as release of heavy metals into the atmosphere. There was a risk of it happening.

[Structure 1 of the invention] The present invention has a rotating scraper plate inside, and a rotating plate on the outer periphery of the scraper plate.
Municipal waste is supplied to a selective crushing and sorting device having a Z screen and selectively crushed and sorted, and the A group is separated from the materials that have passed through the rotating screen, and the A group that passes through the rotating screen without passing through the rotating screen from the end. The B group consisting of discharged substances is separated, and from the A group, through a magnetic separation process, the iron contained in the dry batteries is separated and recovered, and then the dry batteries are separated and recovered in a dry battery separation process in which the iron content is removed.
From the B group, after going through a magnetic separation process to separate and recover the iron containing the dry batteries, the iron content is subjected to a first sieving process in which the dry batteries are sieved as the under-sieve fraction, and then the dry batteries are sieved under the sieve. This dry battery recovery method is characterized by separately recovering dry batteries through a second sieving step in which they are sieved into portions.

The selective crushing and sorting device is disclosed in, for example, Japanese Patent Application Laid-Open No. 55-104990.
It is constructed of a rotating cylindrical screen with protrusions on the inner periphery and a scraper plate that rotates at a different speed from the rotating screen, and is used to collect waste thrown in from the input port at one end of the rotating screen. is crushed by the scraping plate and the protrusions [due to shearing action and collision action], and sequentially moves toward the discharge port on the other end of the cylindrical screen. During this movement, refuse crushed to a size corresponding to the size of the holes passes through the many holes of the rotating screen and exits as the under-sieve. In this under-sieve section, almost all kitchen waste and brittle materials such as glass and ceramics are crushed into granules or flakes along with some weak paper, and the size is small enough to pass through the small holes of the rotating screen. The dry batteries pass through without being crushed and are mixed in and separated. This group of substances is called the A group.

Further, the material under the sieve that does not pass through the small holes of the rotating screen passes through the rotating screen and is discharged from the discharge port. This includes paper, plastic, metal, cloth, etc., but dry batteries that do not pass through the small holes of the rotating screen are also mixed in without being crushed. This substance group is called the B group.

Group B substances are first passed through a magnetic separator to separate the ferrous and non-ferrous components (
plastic, paper, etc.), and non-ferrous materials are processed in a separate process. The iron contains dry batteries, and as shown in FIG. 2, the dry batteries 2 and 3 are sieved by a first sieving means consisting of a two-stage sieve 1, with the dry batteries 2 and 3 as the under-sieve fraction. That is, the opening AI of the upper sieve 1 is set to allow the dry batteries 2 and 3 to pass through, for example, about 5 mm larger than the diameter C of a single dry battery, and this upper sieve 1 allows the passage of the dry batteries 2 and 3, such as iron pieces larger than the largest dry battery 3. For example, empty beverage cans and empty canned cans are separated by sieving.
