Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a waste drum can recycling system for processing and recycling waste drum cans for disposal.
[0002]
[Prior art]
Drums are widely used for storing and transporting various things such as liquid and solid waste. Depending on the application, various types of cans with lids, cans without lids, or constituent materials have been put into practical use.
[0003]
Conventionally, such drums are often limited in the number of times and the period of use due to corrosion or the like, and may not be used if the contents are different.
[0004]
[Problems to be solved by the invention]
Conventionally, used waste drums are often discarded as they are, and there is a problem that resources are not reused.
[0005]
The present invention has been made paying attention to the above-mentioned problems, and can easily recycle used waste drums and can recycle waste drums without wasting valuable resources. The purpose is to provide an integrated system.
[0006]
[Means for Solving the Problems]
The drum can recycling system according to the present invention is a recycling system for recycling drum drums for disposal, in which shredders for crushing waste drum cans and each crushed piece are heated at a temperature of 500 to 600 ° C. Heating means, a granulator for making each piece after heating into granular pellets, and a vibrating screen, and the pellets obtained by the granulator are made into granular steel pellets and powdered steel by a vibrating screen The material is separated and accommodated in a separate container.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing the configuration of a waste drum can recycling system according to an embodiment of the present invention.
[0009]
In the same figure, 1 is an inlet into which a used waste drum can is charged, 2 is an upper and lower two-stage four-axis shredder that crushes the thrown waste drum can, and 3 is a crushed piece heated at a predetermined temperature. A rotary kiln (heating means), 4 is a granulator for making each piece after heating into granular pellets, 5 is a vibrating screen for separating the powdered steel material from the pellets, and the granular steel pellets are put into the container 6 Each steel material is accommodated in a container 7.
[0010]
Reference numeral 8 denotes a secondary combustion furnace provided in the rotary kiln 3. An exhaust gas cooling device 9, a cyclone 10, a dust collector 11, an exhaust fan 12, and a silencer 13 are sequentially connected to the end of the secondary combustion furnace 8.
[0011]
Next, the process flow of the system will be described in detail with reference to the process diagram of FIG.
[0012]
First, the waste drum introduced from the inlet 1 is fed into the upper and lower two-stage four-axis shredder 2 and roughly crushed at the upper part of the shredder 2 and further finely crushed at the lower part (S1). Next, each of the crushed pieces is heated by a rotary rotary kiln 3 at a temperature of 500 ° C. to 600 ° C. (S2), thereby burning paint, residues, etc., and the exhaust gas is discharged from the secondary combustion furnace 8. to go into.
[0013]
Each piece heated by the rotary kiln 3 is sent to the granulator 4 where it is formed into granular pellets (S3). The pellets are further fed into the vibrating screen 5, and the powdery steel material is separated and taken out (S4). The granular steel pellets are accommodated in the container 6, and the powdered steel material is accommodated in the container 7.
[0014]
In this way, used waste drums can be easily recycled, so that valuable resources are not wasted.
[0015]
On the other hand, the combustion product (exhaust gas) in the secondary combustion furnace 8 provided in the rotary kiln 3 is cooled by the cooling device 9, removed through the cyclone 10 and the dust collector 11, and then released into the atmosphere by the exhaust fan 12. Is done. At this time, the silencer 13 suppresses the generation of noise.
[0016]
【The invention's effect】
As described above, according to the present invention, a drum for disposal can be easily recycled, and there is an effect that valuable resources are not wasted.
