JP3620376B2 - Recycling method for recovered paper cups, milk cartons, etc. - Google Patents

Description

[0001]
[Industrial technical field]
The present invention relates to a technology relating to recycling processing of collected paper cups, milk packs, other beverage paper packs, and the like.
[0002]
[Prior art]
Conventionally, once used paper cups and milk cartons, etc. are collected as general waste by the collection and transportation company with beverage manufacturers, vendor companies, other companies, etc. The current situation is that all are incinerated.
[0003]
[Problems to be solved by the invention]
However, the disposal of incineration after use of paper cups and milk cartons, etc. that are produced in large quantities annually has been urgently required to improve early in terms of effective use of paper resources and environmental problems. Therefore, the present invention enables paper cups and milk cartons that have been used once to be effectively recycled at the current processing costs without increasing the payment burden of beverage manufacturers and the like.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the recycling method for recovered paper cups, milk packs, etc. according to the present invention uses a crusher to crush the recovered paper cups, milk packs, etc. into small pieces having a size of about 2 to 10 cm. After the piece is put into a washing machine with a dehydrating device together with the washing water supplied through the water supply pipe, it is washed at high speed, then dehydrated and dried by the high speed rotation of the dehydrating device, sent to the outlet side, and sent to this outlet side Is transferred to a cyclone by a blower and automatically stored in a container pack connected to a cyclone discharge port.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The recycling method for recovered paper cups, milk packs, etc. of the present invention is to smash the recovered paper cups, milk packs, etc. into small pieces of about 2-10 cm in size with a crusher, and supply each of the above small pieces with a water supply pipe. The water is put into a washer with a dehydrator and washed at high speed, and then dehydrated and dried by the high speed rotation of the dehydrator and sent to the discharge port. The small pieces sent to the discharge port are transferred to the cyclone by a blower. And automatically stored in a container pack connected to the cyclone outlet.
Further, the present invention can be implemented as it is for the recycling processing of other beverage paper packs made of the same material as the milk pack.
[0006]
[Example 1]
Embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the paper cup 1 collected after use is processed according to the order of sorting, crushing, washing, dewatering and drying, and packing. Next, a series of apparatuses as shown in FIG. A case where processing is performed using will be described.
In the sorting step, contaminants other than the paper cup are removed from the collected paper cup, and then the paper cup 1 is put into a hopper 4 provided on the upper side of the crusher 3 by the conveyor 2. Although not shown, the loaded paper cup 1 is pushed into the crusher 3 by a certain amount by a pushing bladed shaft for pushing provided in the hopper 4.
Although not shown, the paper cup 1 pushed into the crusher 3 is crushed into strips 5 by meshing with a serrated rotary blade. These strips 5 have different shapes and sizes depending on the structure of the crusher 3 and the size of the rotary blades, etc., but the length of the expanded strip 5 is crushed to a size of about 2 to 10 cm. It is preferable to do.
[0007]
The crushed pieces 5 fall from the drop port 6 provided below the crusher 3 into the washing machine 9 with a dehydrator together with the washing water w supplied from the water storage tank 7 through the water supply pipe 8. ing.
In the washing machine 9, although not shown, washing is performed by high-speed rotation of the washing machine. Thus, the cleaned strip 5 is sent to the connected dehydrating device, dehydrated and dried by the high speed rotation of this device, and automatically sent to the discharge port 10.
[0008]
Reference numeral 11 denotes a sewage tank, which is connected to the lower side of the washing machine so that washing sewage flows in, and is connected so that the sewage can be returned to the water storage tank 7. In the water storage tank, microorganisms are used for purification and the water storage can be used repeatedly.
A blower 12 is provided between the discharge port 10 and the cyclone 13 so that the dried strip 5 can be transferred to the cyclone 13.
Reference numeral 14 denotes a container pack disposed below the cyclone 13, and the strip 5 is automatically accommodated by connecting the opening 15 to the discharge port of the cyclone 13.
[0009]
After being stored in the container pack 14, the packed product is shipped to a paper mill and used as a raw material for toilet paper, paperboard and the like.
If the size of the strip 5 is 2 cm or less, it is easy to flow at the time of cleaning and the cleaning work is difficult, and the strip of 10 cm or more is difficult to clean cleanly.
[0010]
[Example 2]
Similarly to the above example, the processing of the collected milk pack 16 as shown in FIG. 5 is performed according to the order of selection, crushing, washing, dehydration drying, and packing, and the processing methods are all the same as in the above example. The size of the milk pack to be treated in the present invention is usually one having an internal capacity of about 200 cc.
[0011]
【The invention's effect】
By using the present invention, a beverage manufacturer, a vendor company, and other traders such as paper cups and milk cartons can recycle without increasing the processing cost, and can be effectively recycled as paper resources. Accordingly, incineration disposal is not required as in the prior art, and it is beneficial for environmental sanitation.
