DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting paper dust of shavings generated when processing cartons or other packages of milk, soft drinks, seasonings, and other liquid paper containers, so as to facilitate handling. And a device for processing.

[0002]

2. Description of the Related Art Conventionally, paper containers have been constructed such that, in addition to a cut-out piece of paper, the paper must be folded and bonded to reduce the thickness of the paper, so that the paper surface has to be polymerized or the margin has been cut off. In many cases, paper dust is generated by the shaving, and the paper dust is discarded together with the cut-off paper pieces.

[0003]

However, the conventional paper powder is fine and difficult to handle, and not only easily adheres to products such as cartons, but also scatters around and deteriorates the working environment, leading to a decrease in productivity. There is a drawback, and it is conceivable to remove or aspirate the paper dust from the paper container processing workplace or the room where paper dust is likely to be generated, but in any case, the paper dust is discarded together with the paper pieces. In addition to the problem, paper powder is too short in fiber to be used for recycled paper, and extra costs are incurred for disposal transportation and subsequent incineration. , Waste disposal increases and it is inconvenient and uneconomical,
There are drawbacks such as the problem of air pollution. The present invention seeks to properly eliminate these conventional drawbacks, and makes it possible to significantly improve the working environment in the paper container manufacturing process, and to safely and easily collect and dispose of paper dust that is indispensable. The purpose of the present invention is to provide a paper dust collection and processing device that can be granulated in a form that is easy to handle, can be recycled without discarding the paper dust, contributes to effective use of resources, and can be disposed of economically. It is.

And a pug mixer for humidification, mixing and stirring provided through a quantitative discharge mechanism including a rotary valve for quantitatively discharging the wet paper mass humidified by the pug mixer. , A pelletizer for granulating, and the fixed amount discharging mechanism includes a rotating blade and a blade.
Circle feeder with rotatable ridge prevention member
With a rotary valve connected to the outlet of
A paper dust collecting and processing apparatus, which is interposed between the bag filter and a pug mixer .

[0005]

[Function] Paper dust generated in the paper container manufacturing process is suctioned and collected by a blower through an air transportation route, and is introduced into a bag filter. The paper powder separated by the bag filter is discharged to a pug mixer by a circle feeder and a rotary valve in a fixed amount. Then, water, a solvent, a binder and the like are added from the liquid supply port of the pug mixer and humidified, and the paper is conveyed to the discharge port while being kneaded with the conveying and stirring blades. When the lump is continuously supplied to the pelletizer, the lump is placed on a molding die, pushed into the die through-hole by a roller that rolls under pressure on the die, and extruded into a cylindrical shape on the other side. The wet paper web mass sequentially extruded from this die is cut and dropped from the die by the amount of protrusion of an appropriate length with the turning knife cutter,
It is made into a granulated state of a predetermined size, drawn out from the peretta by a rotary plate, carried into a container via a conveyor or directly, and handled and disposed of as a lump, which can be reused as a core material of cardboard and other cardboard .
