JPH0679193A - Refuse selecting and sorting device - Google Patents

Abstract

PURPOSE:To select and sort magnetic refuses such as steel cans and others and non-magnetic refuses such as aluminum cans, glass bottles and others out of the refuses in the state of mixing altogether in compliance with respective kinds with high efficiency, safely and sanitarily. CONSTITUTION:A refuge selecting and sorting device consists of a magnet roll 1 for selecting refuses of various kinds and in large quantities into magnetic refuses and non-magnetic refuses and a wind pressure type weight difference sorting section 4 for selecting and sorting the non-magnetic refuses into the refuses of aluminum cans and the refuses of glass bottles based on the weight difference.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used for event halls, other event halls where a large number of people gather, parking areas, drive-ins, amusement parks, parks, etc. Dust sorting and sorting device that can sort and remove the magnetic wastes and non-magnetic wastes such as aluminum cans, glass bottles, etc. according to their types so that post-processing can be easily performed. It is about.

[0002]

2. Description of the Related Art In a conventional waste disposal device, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 47-2674, the waste is placed on a steel belt, transported in a heating device, burned, and then attached to the steel belt. The scraped thermoplastic material is scraped off with a scraper, or the waste is crushed and then the difference in specific gravity and surface area of the crushed material is measured as described in Japanese Utility Model Publication No. 49-55772. For example, there are those in which the incombustibles and combustibles are separated and sorted and collected respectively.

[0003]

However, various kinds of dusts generated at the above-mentioned event venues, such as iron cans, other magnetic dusts, aluminum cans, glass bottles, and other non-magnetic dusts. It contains various kinds of waste such as various kinds, and it is functionally impossible to sort and sort them by the above-mentioned conventional waste disposal equipment. The current situation is that they are carried out and discarded as they are, or they are manually sorted by type.

However, the manually sorted sorting has a remarkably low processing capacity, is dangerous, and is very unhygienic because odors, dusts, etc. of spoiled products are trapped therein.
There were various problems.

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and in a waste in a mixed state of iron cans and other magnetic wastes, aluminum cans, glass bottles and other non-magnetic wastes In a dust sorting and sorting apparatus that sorts and sorts more, a magnet roll body equipped with a conveyer for carrying in magnetic substances and non-magnetic substance dust is disposed, and a magnetism releasing portion and a non-magnetic substance are taken out at a required position below the magnet roll body. A conveyor is provided, and a wind pressure type weight difference sorting section is provided at the carry-out section of the non-magnetic material carry-out conveyor.

1 and 2 show an embodiment of the present invention, in which FIG. 1 is a schematic front view of the entire apparatus with a main part cut away,
FIG. 2 is a partially enlarged sectional view showing an example of the magnet roll body.

In FIG. 1, reference numeral 1 is a magnet roll body, and as shown in FIG.
A non-magnetic material waste carry-in conveyor 2 around which the carry-out end is wound is used, but the invention is not limited to this. 1b
Is a magnetism releasing portion provided at a required position below the magnet roll body 1, and the belt 2a may be separated from the magnet roll body 1 as shown in the drawing, or a scraping body (such as a dog knife). The magnetic body a (iron can or the like) may be separated from the magnet roll body 1 by (not shown). Reference numeral 3 denotes a conveyer for carrying out a non-magnetic material, which is for carrying out a non-magnetic material b such as an aluminum can or a glass bottle which is not magnetically attached to the magnet roll body 1. Reference numeral 4 denotes a wind pressure type weight difference sorting section arranged at the unloading section of the non-magnetic material unloading conveyor 3, which comprises, for example, a blowout nozzle section 4a continuous to a required blower (not shown) and has a required width. The aluminum can b ′ and the glass bottles b ″ are operated by constantly blowing air at a constant pressure over a constant direction.
Are configured to be selected by utilizing the weight difference. Denoted at 5a, 5b, and 5C are respective dust removal portions, which are 5a.
Is a magnetic material a take-out part, 5b is a glass bottle b "take-out part, 5c is an aluminum can b'take-out part. The take-out parts 5a, 5b and 5c are taken out according to the type of each garbage. As long as it is obtained, its structure and installation location are arbitrary.

Next, the operation will be described. The magnetic cans, such as iron cans and other magnetic substances a, and the aluminum cans, glass bottles and other non-magnetic substances b, which have been dropped onto the conveyer 2 for carrying in magnetic substances and non-magnetic substances, are conveyed to the magnet roll body 1 side.
When the magnetic material a such as an iron can among the dust carried into the magnet roll body 1 is magnetically attached to the magnet roll body 1 and reaches the demagnetization portion 1b, the magnetism is released and the ejection portion 5a is removed. Taken out to.

Further, the non-magnetic material b such as aluminum cans and glass bottles is discharged by the non-magnetic material carrying-out conveyor 3, and when it reaches the discharging end, it is always discharged from the blowing nozzle 4a of the wind pressure type weight difference sorting section 4. The aluminum can b ′ is blown to the take-out section 5C by the wind pressure blowing at a constant pressure in a certain direction, the glass bottles b ″ are dropped to the take-out section 5b, and each dust is sorted and sorted according to its type. is there.

[0010]

According to the present invention, in a dust sorting apparatus for sorting iron cans and other magnetic dusts and aluminum cans, glass bottles and other non-magnetic dusts from mixed dusts, a magnetic substance A magnet roll body provided with a conveyor for carrying in non-magnetic material waste, and a magnetism releasing portion and a non-magnetic material carry-out conveyor provided at a required position below the magnet roll body for carrying out the non-magnetic material. A wind pressure type weight difference sorting unit is provided at the carry-out section of the conveyor, and iron cans and other magnetic debris and aluminum cans, non-magnetic debris such as glass bottles do not require any manpower and are highly efficient. The present invention has an effect that it can be sorted and sorted according to the required type so that the post-treatment can be performed safely and hygienically in accordance with each type.
