Description

  The present invention relates to a so-called milk carton filled with a liquid beverage such as milk, separated into a paper component mainly composed of pulp fiber as a base material and a plastic film as a laminate material, and a paper liquid for collecting each of them. The present invention relates to an apparatus for separating a paper portion of a container and a plastic film.

  In a paper mill, this type of milk carton is separated into a paper portion mainly composed of pulp fibers and a plastic film, and the paper portion is utilized as a recycled resource as a raw paper raw material. On the other hand, processing of plastic films is entrusted to processing companies at a processing cost. Among these plastic films, those having relatively high purity and can be used as a raw material for RPF (Refuse Paper & Plastic Fuel) (solid fuel) are used for the production of RPF. On the other hand, if the paper contains a lot of moisture that is not suitable for RPF raw materials, or if it contains metal or other impurities such as staples or clips, it may be incinerated. doing. In addition, in the case where the purity is higher than that used as the RPF raw material, it is sold to a recovery company as a raw material for recycled plastic, for example.

  It is not preferable to incinerate the plastic film from the viewpoint of effective use of resources and environmental measures, and it is preferable that the plastic film be recovered so that it can be used effectively as a raw material for RPF as much as possible. Paper mills outsource the processing of plastics separated from milk cartons to collection companies, but the reality is that the costs are outsourced to collection companies, and RPF is used as the plastic film to be collected. When many plastic films are used as raw materials, the burden cost is low, and when many impurities are contained, the burden is high because the waste is incinerated.

  When entrusting the processing of plastic film separated from milk carton, if the plastic film contains a lot of pulp fiber or other paper content with high water content, good quality RPF with stable energy efficiency Can not be generated, it is classified as a plastic film containing impurities, and the processing commission price may increase. In order to reduce the processing commission price, it is desired to improve the purity of the plastic film by separating and removing the paper as much as possible and further drying it.

  By the way, in Patent Document 1, the laminated waste paper with the paper attached to the back side is cut, the cut laminated waste paper and water are mixed and stirred, the paper is separated from the back side of the laminated waste paper, and the laminate film is separated. A method for treating waste laminated paper has been proposed, in which at least the laminate film can be reused as an industrial material by separating it into paper and paper, and the laminate film that has been regarded as waste can be reused as an industrial material. ing.

JP-A-9-38629

  In the method of separating laminated waste paper according to the invention disclosed in Patent Document 1, the removal rate of the paper is still low, and therefore the amount of water is large, and the purity of the plastic film when entrusted to a collection company is sufficiently increased. There is a possibility that it is classified as a plastic film containing impurities.

  In view of this, the present invention provides a paper liquid container for improving the purity of a plastic film by improving the recovery rate of the paper when the recovered milk carton is separated into a paper and a plastic film. An object of the present invention is to provide a separation device for plastic and plastic film.

  As a technical means for achieving the above object, the paper liquid container and plastic film separating device of the paper liquid container according to the present invention is formed by laminating a plastic film on a sheet mainly composed of pulp fiber. A separation device for separating the paper portion and the plastic film of the paper-made liquid container, wherein the paper-liquid container is crushed into a plastic film to be treated of an appropriate size, and the paper portion of the plastic film to be treated is separated. Water is supplied to the crushed plastic film until the water content reaches 70% by weight or more in a paper liquid container separation device for separating a plastic liquid film from a paper liquid container. Applying an impact to the moisture supply device and the plastic film to be treated having the moisture-containing paper, And a minute and paper separator device for separating the plastic film is characterized in that separate the paper fraction and a plastic film is recovered, respectively.

  The recovered paper liquid container such as a milk carton is cut, crushed and produced into a plastic film to be treated, and then supplied to the moisture supply device. In the water supply device, the water content of the paper constituting the plastic film to be treated is adjusted to 70% by weight or more by supplying water, and supplied to the paper separation device. In the paper separator, an impact is applied to the plastic film to be processed by colliding a plate material, a bar material or other appropriate members. Since the paper content of the plastic film to be processed contains an appropriate amount of moisture, the impact of the paper will separate from the plastic film by this impact, and the paper content and the plastic film can be separated. These paper and plastic film are collected respectively. In addition, it is preferable to set it as 70 weight% or more as a water | moisture content for fully separating a paper part from a plastic film, and it is more preferable to set it as 80 weight% or more.

  In addition, when supplying the plastic film to be processed to the moisture supply device, a conventional separation process for separating the milk carton into a paper part and a plastic film is performed, and the state where separation is insufficient even after the process is performed. In other words, it is more reliable to supply a plastic film with paper attached than when it is immediately supplied to the moisture supply device without going through a conventional separation process. It is preferable. In addition, when the plastic film to be processed that has been cut and crushed in the conventional separation process is too large to be supplied to the paper separation device, it is further cut and crushed before being supplied to the moisture supply device. It takes a thing. This is because when the plastic film to be processed is large, it is difficult to give an impact over the entire area of the plastic film to be processed. Therefore, if the paper separation device is cut and crushed into a size that can give a sufficient impact by the conventional separation step, prior to supplying the moisture supply device, It is not necessary to go through the process of cutting and crushing to make it smaller.

  After the plastic film is collected and dried, the processing can be outsourced to a plastic film collection company.

  According to a second aspect of the present invention, there is provided a separation apparatus for separating a paper portion and a plastic film of a paper liquid container, wherein the paper separation device is divided into a cylindrical separation container having a horizontal axis as a central axis, and the separation container. A rotating shaft that rotates about a horizontal axis, a plurality of plates implanted on the rotating shaft at appropriate intervals in the axial direction and the circumferential direction of the rotating shaft, and the tip of the plate face each other The screen is made of a cylindrical perforated plate centering on the central axis of the separation container, and the plastic film to be treated supplied into the separation container is agitated by the rotation of the rotating shaft. At the same time, an impact is applied to the plastic film to be treated to remove the paper from the plastic to be treated, and the separated paper is passed through the through-holes of the screen. Is recovered paper fraction adhering to the outer peripheral surface of the falling or screen from down, is characterized in that the paper fraction is separated to recover the treated plastic film remaining inside the screen.

  The plastic film to be processed supplied to the paper separation device is agitated by turning the plate in the separation container. At this time, the plastic film to be processed receives centrifugal force and moves to the inner wall side of the separation container due to the turning speed of the plate, and is hit by the plate and an impact is applied. Minutes leave. Further, when the paper portion and the plastic film move, they collide with the screen. At this time, the paper portion passes through the through-hole of the screen, and the plastic film does not pass. In addition, let the diameter of a through-hole be the magnitude | size which prevents passage of a plastic film, or let the magnitude | size of the plastic film cut and crushed be the magnitude | size which does not pass this through-hole.

  The paper portion that has passed through the through-hole of the screen falls from the screen or adheres to the outer peripheral surface of the screen. The paper part adhering to the outer peripheral surface of the screen is subsequently pushed out and dropped by the paper part that is about to pass through the through hole. These papers are collected from the lower part of the separation container.

  On the other hand, the plastic film having a small bulk specific gravity receives the wind pressure generated by the rotation of the plate, is pressed by the screen, and remains inside the screen. If these plastic films are collected, for example, a high-purity plastic film suitable for recycled plastics can be collected.

BRIEF DESCRIPTION OF THE DRAWINGS It is a figure explaining the schematic structure of the separation device of the paper part and plastic film of the paper-made liquid container concerning this invention, and is shown with sectional drawing cut | disconnected by the surface along an axial direction. It is sectional drawing cut | disconnected by the axis orthogonal surface of the paper separation device shown in FIG.

  Hereinafter, based on a preferred embodiment shown in the drawings, a paper separator and a plastic film separating device of a paper liquid container according to the present invention will be described in detail.

  FIG. 1 shows a paper separation device 1 which is a paper liquid container separation device and a plastic film separation device. The separation device mainly comprises a paper separation device 1 and a treatment tank 4 which is a water supply device. Has been. The paper separation device 1 is supplied with a plastic film 2 to be treated, which is made of a plastic film from which paper content mainly composed of pulp fibers is to be separated, from an input port 11. The plastic film 2 to be treated is supplied to the treatment tank 4 after the recovered paper liquid container M such as a milk carton is cut and crushed in the cutting / crushing step 3. In the treatment tank 4, water is sprinkled to adjust the water content to be 70% by weight or more, and then charged from the inlet 11. In addition, it is preferable that the water content is 80% by weight or more because the action described later can be performed better.

  In the paper separating apparatus 1, a cylindrical screen 13 made of a perforated plate is accommodated inside a cylindrical separation container 12 centered in the horizontal direction, and a plurality of plates 14 are accommodated inside the screen 13. ing. The plate 14 is implanted on the outer peripheral surface of the rotary shaft 15 with the axial direction of the rotary shaft 15 being rotatable about the axis of the separation container 12 as the width direction. As shown in FIG. 1, the plates 14 are arranged such that the mounting angles in the circumferential direction of the rotating shaft 15 have an alternate positional relationship along the axial direction. Further, the skew plate 14a serving as a conveying means located below the inlet 11 is attached to the rotary shaft 15 at an angle of about 45 ° with respect to the direction of the rotary shaft 15 in the width direction. The treated plastic film 2 is pushed to the side where the plate 14 is disposed. It should be noted that any interval relating to the mounting position of the plate 14 in the axial direction and the circumferential direction is set so as to satisfactorily perform the action described later. The screen 13 is arranged facing the tip of the plate 14.

  The diameter and pitch of the through holes of the perforated plate forming the screen 13 are supposed to perform the functions described later satisfactorily. A plurality of scrapers 16 slide on the outer peripheral surface of the screen 13 in the axial direction of the rotary shaft 15 so that the outer peripheral surface of the screen 13 is scratched. That is, each of the scrapers 16 is slidable in the axial direction along the guide shaft 16a in a direction parallel to the axis of the rotary shaft 15. This sliding is performed by driving means 16b attached to the guide shaft 16a so as to correspond to the respective scrapers 16. The screen 13 is attached to a rotating plate 17 that rotates about the rotating shaft 15. The rotating plate 17 transmits output rotation of a drive motor or the like (not shown) via a transmission. To rotate. For this reason, the screen 13 turns around the rotation axis 15.

  A watering nozzle 18 is provided as a moisture supply device below the inlet 11 of the separation container 12, and water is sprayed from the watering nozzle 18 toward the inside of the separation container 12. Further, as shown in FIG. 2, a plastic discharge port 21 communicating with the inside of the separation container 12 is provided at the end opposite to the input port 11. The lower part of the separation container 12 is an inclined wall, and a paper discharge port 22 is provided at the lowermost part of the inclined wall. As the water supply device, either one or both of the treatment tank 4 and the watering nozzle 18 can be installed.

  The operation of the separating device for separating the paper content and the plastic film of the paper liquid container constituted as described above will be described below.

  The recovered paper liquid container M is subjected to the cutting / crushing step 3 and is crushed to an appropriate size to be produced on the plastic film 2 to be processed. The plastic film 2 to be treated is supplied to the treatment tank 4 and sprinkled to adjust the moisture to 70% by weight or more. The water content at this time is more preferably 80% by weight or more.

  The plastic film 2 to be processed in which the moisture content is 70% by weight or more is fed from the processing tank 4 through the inlet 11 of the paper separator 1. The inputted plastic film 2 to be treated further contains moisture with shower water sprayed from the watering nozzle 18. In addition, it is necessary to provide the said processing tank 4 when the water | moisture content contained can be made into 70 weight% or more by watering from the water spray nozzle 18 to the to-be-processed plastic film 2 thrown in in the crushed state. There is no. Alternatively, when the moisture can be increased to 70% by weight or more in the treatment tank 4, the watering by the watering nozzle 18 becomes unnecessary. If both the treatment tank 4 and the watering nozzle 18 as these water supply devices are provided, the amount of treatment can be achieved by using either or both according to the amount of plastic film to be treated and the amount of paper. It is possible to easily cope with fluctuations and the like, and to ensure a desired amount of moisture.

  The plastic film 2 to be treated falls by being sprinkled with water, is supplied to the skew plate 14a, is pushed by the skew plate 14a by the rotation of the rotating shaft 15, and is stirred by the plate 14. Feeded to the area. The plate 14 is swung by the rotation of the rotating shaft 15, and by rotating at a suitable speed, the plastic film 2 to be treated is blown away to the outer peripheral side in the separation container 12 due to the wind pressure due to the swirling of the plate 14. Struck by the plate 14. Since the plastic film 2 to be treated has a high moisture content, the paper portion is peeled off from the plastic film by the impact of being struck, and is further crushed and made fine. Further, when the paper and the plastic film are blown to the outer peripheral side of the separation container 12 due to the wind pressure, they collide with the screen 13. At this time, the paper portion passes through the through hole of the screen 13 due to the impact of the collision and is pushed out to the outer peripheral side of the screen 13. On the other hand, since the plastic film is not crushed even if it is struck by the plate 14, it does not pass through the through holes of the screen 13, and the bulk specific gravity is small. It will be.

  The pulp fibers that are the main component of the paper need to be unwound so that the size of the paper can pass through the through holes of the screen 13. Since the pulp fibers can be easily broken, the water content of the paper is preferably 70% by weight or more, more preferably 80% by weight or more. However, if the amount of moisture becomes too large, stirring and scattering by the plate 14 may not be performed smoothly.

  The plastic film floating in the screen 13 receives the wind pressure due to the rotation of the plate 14 and is gradually conveyed downstream. It should be noted that adjustment is made by changing the shape, mounting angle, and the like of the plate 14 so that this movement is performed smoothly. The plastic film conveyed to the downstream side is discharged from the plastic discharge port 21 by the swirling air generated by the swirling of the plate 14 and collected. The recovered plastic film has a high purity because the paper is sufficiently separated.

  On the other hand, the paper portion that has passed through the through holes of the screen 13 is pushed out of the through holes and falls along the outer peripheral surface of the screen 13, or adheres to the outer peripheral surface. Since the scraper 16 moves in the axial direction of the rotary shaft 15 while rubbing the outer peripheral surface of the screen 13, the paper portion adhering to the outer peripheral surface is scraped off by the scraper 16 and falls. Then, the dropped paper portion is discharged out of the separation container 12 through the paper portion discharge port 22 and collected. In addition, since the screen 13 is swiveling, the scraper 16 scrapes the entire area of the outer peripheral surface of the screen 13 to scrape off the paper, thereby efficiently collecting the paper.

  The collected plastic film is used as RPF raw material, and the recovered paper is used as used paper raw material.

  According to the paper liquid container and plastic film separating apparatus of the paper liquid container according to the present invention, the plastic film and the paper content can be easily and reliably separated, so that high-purity plastic can be recovered and plastic recycling. To contribute to maintaining a good environment.
