Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is designed to collect a large amount of miscellaneous garbage that is generated mainly at event venues, other venues where large numbers of people gather, parking areas, drive-ins, amusement parks, parks, etc. The present invention relates to a cylindrical rotary sieve device in a garbage sorting and sorting device that can be used to sort and take out waste by sieving according to required types so that post-processing can be easily performed.

0002

[Prior Art] In conventional garbage processing equipment, for example, as disclosed in Japanese Utility Model Application Publication No. 47-2674, waste is placed on a steel belt and transferred through a heating device, and after being burned, the waste adheres to the steel belt. The thermoplastic material in the waste is scraped off with a scraper, or as in Japanese Utility Model Application Publication No. 49-55772, the waste is crushed and then the difference in specific gravity and surface area of the crushed waste is calculated. There are devices that use this method to separate and sort noncombustible materials and combustible materials, and collect them separately.

0003

[Problem to be Solved by the Invention] However, the garbage generated at the event venue etc. is a variety of miscellaneous items, such as:
Paper, trays, paper containers (lunch boxes, cups, etc.), plastic containers, iron cans, aluminum cans, glass bottles, leftovers, cigarette butts, chopsticks, and other combustible and non-combustible miscellaneous garbage, etc. It contains garbage, and it is functionally impossible to sort and sort it by type using the conventional garbage disposal equipment mentioned above, so normally a designated garbage disposal company carries it out of the venue in bulk and disposes of it as is. At present, they are either sorted by type or manually sorted by type.

[0004] However, manual sorting has extremely low throughput, is dangerous, and is extremely unhygienic due to the smell of rotting products, dust, etc.
There were various problems.

[0005]

[Means for Solving the Problems] The present invention aims to solve the above-mentioned problems, and provides a garbage sorting and sorting device for sorting and sorting various types of garbage in a mixed state according to type. A cylindrical rotating sieve body is installed to form a mesh sieve part and tilted at a required angle with the garbage inlet side at a high position and the garbage outlet side at a low position, and a cylindrical rotary sieve body is installed at a lower side and an outlet side of the cylindrical rotary sieve body, respectively. This is characterized by the provision of a conveyor for discharging garbage that passes through the mesh and a conveyor for discharging garbage that does not pass through the mesh.

It is not limited to. Reference numeral 6b denotes a magnetic release part provided at a predetermined position below the magnet roll body 6, and the belt 5a may be separated from the magnet roll body 6 as shown in the figure. (not shown) may be used to separate the magnetic body b3 (such as an iron can) from the magnet roll body 6. Reference numeral 7 denotes a conveyor for transporting non-magnetic materials, and is used to transport non-magnetic materials b4 such as aluminum cans and glass bottles that are not magnetically attached to the magnetic roll body 6. Reference numeral 8 denotes a wind pressure type weight difference sorting section disposed at the discharge section of the conveyor 7 for carrying out non-magnetic materials, which comprises, for example, a blowing nozzle section 8a connected to a required blower (not shown), and has a required width. It is configured to sort aluminum cans b4' and glass bottles b4'' by utilizing the difference in weight by constantly blowing air at a constant pressure in a constant direction over the area. 9a, 9b
, 9c, 9d, and 9e are respective garbage removal sections, where 9a is a garbage removal section, 9b is a garbage extraction section for garbage b3 (magnetic materials such as iron cans), and 9c is a garbage extraction section for garbage b4'' (glass bottles). Part, 9
d is a part for taking out the trash b4' (aluminum can), and 9e is a part for taking out the trash c. Note that the dust b1 is the dust c as shown in FIG.
They may be taken out together or, although not shown, may be taken out separately.In short, the structure and installation location are arbitrary as long as each type of garbage can be sorted and taken out. Reference numeral 10 denotes a dust supply device such as a transfer conveyor for supplying dust to the cylindrical rotary sieve body 1, but the present invention is not limited thereto, and a bucket device or other suitable supply means can be used.

Next, the operation will be explained. Among the various miscellaneous garbage fed into the cylindrical rotary sieve body 1 by the transfer conveyor 10, cigarette butts, leftover food, chopsticks, and other fine garbage a that can pass through the mesh are transferred to the mesh section 1.
