Description

この発明は、一般に、建設廃材の一部として排出される廃石膏ボードのリサイクル装置に関し、特に廃石膏ボードを破砕し、破片状態で石膏と紙の分離を効率的に行うようにした廃石膏ボードのリサイクル装置に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a recycling apparatus for waste gypsum board that is discharged as a part of construction waste, and in particular, waste gypsum board that is crushed and efficiently separates gypsum and paper in a broken state. Related to recycling equipment.

従来、廃石膏ボードは、その大部分が硫酸カルシウムの鉱物である為に、安定型廃棄物として扱われていて、埋立処理されていた。しかし、石膏ボードは、板状の石膏を両側から紙で挟んで破損しにくく構成されている為に、廃棄されて埋立処理された後に紙や接着剤が雨水等を吸って腐食し、悪臭を発生する事態を招いていた。石膏は、天然鉱物で再利用が可能であり、また紙も分離後に再生紙にリサイクルされ得るものである。   Conventionally, most of the waste gypsum board is a mineral of calcium sulfate, so it has been treated as a stable waste and landfilled. However, gypsum board is constructed so that it is hard to break by sandwiching plaster plaster with paper from both sides, so after it is discarded and landfilled, the paper and adhesive will corrode by sucking rainwater etc. Invite the situation to occur. Gypsum is a natural mineral that can be reused, and paper can be recycled into recycled paper after separation.

そこで、近年幾つかの廃石膏ボードのリサイクル装置が開発され、提案されている。例えば下記特許文献に開示されている石膏ボードの粉砕選別機は、一端部に石膏ボードの投入口を有し、内側の中間部から他方端部にかけて多数の透孔を形成した水平筒体と、その内部で回転可能に支持され、回転駆動されて投入石膏ボードを内側の他方端部に粉砕、搬送するスクリューコンベヤと、水平筒体の内側他方端部の多数の透孔を被うように水平に回転可能に機台及び若しくは水平筒体に支持され、回転駆動装置によって回転駆動されて石膏粉を多孔から落下させ且つ内面の螺旋体でシート片を一端部の開口へ送って落下させる多孔ケーシングとから構成されている。   In recent years, therefore, several waste gypsum board recycling apparatuses have been developed and proposed. For example, a gypsum board crushing and sorting machine disclosed in the following patent document has a gypsum board inlet at one end, and a horizontal cylinder formed with a large number of through holes from the inner middle part to the other end part, It is supported so that it can rotate inside, and it is driven to rotate and crushes and conveys the input gypsum board to the other end on the inside, and horizontally so as to cover many through holes at the other end on the inside of the horizontal cylinder. A porous casing that is rotatably supported by a machine base and / or a horizontal cylinder, is driven to rotate by a rotary drive device, drops gypsum powder from the pores, and sends a sheet piece to an opening at one end by a spiral on the inner surface; It is composed of

特開平10−5615JP-A-10-5615

前記特許文献に開示されている石膏ボードの粉砕選別機は、コンパクトにまとまった構造で設置面積が少ないと言う長所を持っているが、石膏粉の分離が自然落下によって行っているだけであり、分離作業効率が低いものであり、また紙に連れて石膏粉が排出されてしまい、石膏粉/紙の分離が不十分であると言う短所も持っている。   The gypsum board crushing and sorting machine disclosed in the patent document has the advantage that the installation area is small with a compact structure, but the gypsum powder is only separated by natural fall, The separation work efficiency is low, and the gypsum powder is discharged along with the paper, and the gypsum powder / paper is not sufficiently separated.

The waste gypsum board that has been thrown into is preferably crushed into pieces of about 2 cm square to about 12 cm square and the helix that carries the debris and gypsum powder to the outlet, and the helix is preferably driven at 5 to 30 RPM. The cylindrical casing has a first part in which a plurality of strips extending in the longitudinal direction are spaced apart as a fixed blade in the circumferential direction, and a comb projecting inwardly on the inner surface on the downstream side Consists of a second part with teeth separated in the longitudinal direction as a plurality of fixed blades, and a third part that is provided further downstream and collects fragments and gypsum powder generated by crushing the first part and the second part And the spiral is Corresponding to the first part of the cylindrical casing, there is a first part projecting a plurality of blades around so as not to interfere with the strip fixed blade, and a second part of the cylindrical casing there A second part having spiral blades so as not to interfere with the comb-tooth fixed blade and a third part having only a shaft corresponding to the third part of the cylindrical casing and having neither fixed blades nor spiral blades.

前記筒状ケーシングの第三部は、前記筒状ケーシングの第二部との連通開口部に錘によって閉じるように付勢された邪魔板を内部に有することができる。   The third part of the cylindrical casing may have a baffle plate urged to close by a weight at a communication opening with the second part of the cylindrical casing.

前記螺旋体の第一部分の刃物は、同じ位相に揃わないように90度よりも若干大きいピッチで、好ましくは92.5度から95度の範囲のピッチで螺旋羽根に取り付けられる。   The blades of the first part of the spiral body are attached to the spiral blades at a pitch slightly larger than 90 degrees, preferably at a pitch in the range of 92.5 degrees to 95 degrees so as not to align with the same phase.

前記搬送手段は、前記破砕手段の前記螺旋体から構成されたり、又は前記破砕手段の前記螺旋体と、前記横長の筒状ケーシングの一方端部の排出口に受け入れ口を接続すると共に前記紙/粉末分離手段の筒状ケーシング及び筒状スクリーンの受け入れ口に破片及び石膏粉末を搬送するスクリューコンベヤと、該スクリューコンベヤの回転駆動手段とからも構成される。   The conveying means is composed of the spiral body of the crushing means, or a receiving port is connected to the spiral body of the crushing means and a discharge port at one end of the horizontally long cylindrical casing, and the paper / powder separation is performed. A screw conveyor that conveys debris and gypsum powder to a cylindrical casing and a receiving port of a cylindrical screen of the means, and a rotational driving means of the screw conveyor.

前記紙/粉末分離手段の回転体は、約10m/秒から約30m/秒の周速度で回転する複数の螺旋羽根を有し、それら螺旋羽根は、交互に受け入れ口側と紙排出口側にずれて配置される。   The rotating body of the paper / powder separation means has a plurality of spiral blades rotating at a peripheral speed of about 10 m / second to about 30 m / second, and these spiral blades are alternately arranged on the receiving port side and the paper discharge port side. They are shifted.

前記紙/粉末分離手段の石膏粉末の排出部は、スクリューコンベヤから構成される。
また、前記投入口は、開閉可能な蓋を有し、該蓋の開閉をスイッチで検出して、該蓋の開放時には少なくとも前記破砕手段の運転を停止し、該蓋の閉鎖時に本リサイクル装置の運転が可能になるように構成される。
更に、 前記破砕手段の一対の螺旋体は、互いに干渉しないように離れて配置され、また各々個別の可逆転の駆動手段によって回転駆動され、所定の回転抵抗を受けると所定回転数だけ逆転できるように構成される。

Further, the pair of crushing members of the crushing means are arranged apart from each other so as not to interfere with each other, and are rotationally driven by individual reversible driving means so that they can be reversed by a predetermined number of rotations when receiving a predetermined rotational resistance. Composed.

従って、本発明に係る廃石膏ボードのリサイクル装置によれば、投入口から投入された紙付きの廃石膏ボードが破砕手段によって破砕された破片及び石膏粉末は紙/粉末分離手段に搬送手段によって搬送され、そこで紙片と石膏粉末とに連続的に分離されることになる。その際に、破片及び石膏粉末は、受け入れ口から筒状スクリーン内に搬送されて、内部で回転駆動されている分離回転体の螺旋羽根によって遠心力が与えられて1mmから7mm幅の細長いスリットを多数形成した周囲壁の内側に衝突して更に粉砕され、粉砕と同時に石膏粉末がスリットを通して筒状ケーシング内に排出され、下部の石膏粉末の排出部に集まってから排出されて行く。他方、周囲壁の内側への衝突による粉砕で同時に分離された紙片は、筒状スクリーン内で螺旋羽根の回転によって起こされている紙片排出口へ向
かった搬送風によって搬送されて排出されて行く。かくして確実に粉砕と分離がスクリーンへの衝突によって行われると共に、石膏粉末/紙片の分離作業が速く、廃石膏ボードを高い分離性能で石膏粉末と紙片とに分離することができる。1mmから7mm幅の細長いスリットは、絶えず内側から遠心力で飛んでくる破片及び石膏粉末によって衝撃を受けており、詰まることが無く、分離作業の速さ向上に寄与している。分離の不十分な破片は、重く遠心力が作用し、搬送風によって搬送される前にスクリーンに衝突させられることになり、石膏粉末と紙片の分離が促進され、混合排出が防止され分離精度が向上される。
Therefore, according to the recycling apparatus for waste gypsum board according to the present invention, the debris and gypsum powder that has been crushed by the crushing means and the waste gypsum board with paper that has been input from the inlet is conveyed to the paper / powder separation means by the conveyance means. There, it is continuously separated into a piece of paper and gypsum powder. At that time, the debris and gypsum powder are transported from the receiving port into the cylindrical screen, and centrifugal force is applied by the spiral blades of the separating rotating body that is driven to rotate inside, thereby forming elongated slits having a width of 1 mm to 7 mm. It collides with the inside of a large number of surrounding walls and is further pulverized. At the same time as the pulverization, the gypsum powder is discharged into the cylindrical casing through the slit, and is collected after being collected in the discharge part of the lower gypsum powder. On the other hand, the paper pieces simultaneously separated by crushing due to the collision to the inside of the surrounding wall are conveyed and discharged by the conveying air toward the paper piece discharge port caused by the rotation of the spiral blade in the cylindrical screen. Thus, the crushing and separation are surely performed by collision with the screen, the gypsum powder / paper piece separation operation is fast, and the waste gypsum board can be separated into the gypsum powder and the paper piece with high separation performance. The elongated slits with a width of 1 mm to 7 mm are constantly impacted by debris and gypsum powder flying from the inside by centrifugal force, and are not clogged, contributing to an improvement in the speed of separation work. Insufficient separation fragments are heavily subjected to centrifugal force and are made to collide with the screen before being conveyed by the conveying air, which promotes separation of gypsum powder and paper pieces, prevents mixed discharge, and improves separation accuracy. Be improved.

破砕手段の上部の投入口から投入される廃石膏ボードは、横長の筒状ケーシングの内部において、駆動手段によって5から30RPMで回転駆動される一対の螺旋体によってそれらの間で上から下に噛み込まれ、紙/粉末分離手段のスクリーンに当てるのに好適な約2cm平方から約12cm平方程度の破片に連続的に破砕され、また破砕で生じる破片及び石膏粉末が螺旋体によって排出口に連続的に搬送される。   Waste gypsum board thrown in from the top of the crushing means is bitten from top to bottom by a pair of spiral bodies that are driven to rotate at 5 to 30 RPM by the drive means inside the horizontally long cylindrical casing. It is rarely broken into pieces of about 2 cm square to about 12 cm square, which are suitable for applying to the screen of the paper / powder separating means, and the pieces and gypsum powder generated by the crushing are continuously conveyed to the discharge port by the spiral. Is done.

搬送手段が破砕手段の螺旋体から構成されると、破砕手段にすぐ紙/粉末分離手段に接続して廃石膏ボードのリサイクル装置をコンパクトに構成することができる。また搬送手段を、破砕手段の螺旋体と、横長の筒状ケーシングの一方端部の排出口に受け入れ口を接続すると共に紙/粉末分離手段の筒状ケーシング及び筒状スクリーンの受け入れ口に破片及び石膏粉末を搬送するスクリューコンベヤと、該スクリューコンベヤの回転駆動手段とから構成することで、破砕手段と紙/粉末分離手段が互いに水平方向に及び/又は垂直方向に離れていても連続的に廃石膏ボードのリサイクル装置の運転を行うことができる。   When the conveying means is composed of the spiral body of the crushing means, the waste gypsum board recycling apparatus can be made compact by connecting to the crushing means immediately with the paper / powder separation means. In addition, the conveying means is connected to the spiral body of the crushing means and the discharge port at one end of the horizontally long cylindrical casing, and to the cylindrical casing of the paper / powder separation means and the receiving port of the cylindrical screen, fragments and gypsum By comprising a screw conveyor for conveying the powder and a rotational drive means for the screw conveyor, the waste gypsum is continuously produced even if the crushing means and the paper / powder separating means are separated from each other in the horizontal direction and / or the vertical direction. The board recycling device can be operated.

筒状ケーシングでは、その内面に長手方向に延びた複数の条材を周方向に固定刃として隔設した第一部において、そこの条材固定刃と干渉しないように周囲に複数の刃物を突設した螺旋体の第一部分によって効果的に廃石膏ボードを破砕して紙と石膏粉とを分離することができる。更に、下流側の内面に内側に突出した櫛歯を長手方向に複数固定刃として隔設した筒状ケーシングの第二部において櫛歯と螺旋羽根とによって廃石膏ボード破片を粉砕して紙片と石膏粉末とに分離するのを促進することができる。更に下流側に設けられて第一部と第二部で破砕されて生じた紙片及び石膏粉末を筒状ケーシングの固定刃も螺旋羽根も無い軸だけの第三部に紙/粉末分離手段への搬送のために収集できる。   In the cylindrical casing, in the first part where a plurality of strips extending in the longitudinal direction are provided as fixed blades in the circumferential direction on the inner surface, a plurality of blades project around the periphery so as not to interfere with the strip fixed blades. The waste gypsum board can be effectively crushed and the paper and gypsum powder can be separated by the first part of the provided spiral body. Further, the waste gypsum board fragments are crushed by the comb teeth and the spiral blades in the second part of the cylindrical casing in which the comb teeth projecting inward on the inner surface on the downstream side are spaced apart as a plurality of fixed blades in the longitudinal direction. Separation into powder can be facilitated. Further, a piece of paper and gypsum powder, which are provided on the downstream side and are crushed by the first and second parts, are transferred to the third part of the cylindrical casing with no fixed blades and no spiral blades. Can be collected for transport.

筒状ケーシングの第三部では、筒状ケーシングの第二部との連通開口部に錘によって閉じるように付勢された邪魔板によって破片が楽に第二部から流入して来るのが邪魔され、第一部及び第二部で繰り返し粉砕されると共に、石膏ボード破片は、螺旋体によって互いに擦りあわされてほぼ完全に紙片と石膏粉末とに分離されるようになる。   In the third part of the cylindrical casing, the baffle plate that is urged to close by the weight to the communication opening with the second part of the cylindrical casing is obstructed from easily flowing in the fragments from the second part, While being repeatedly pulverized in the first part and the second part, the gypsum board fragments are rubbed against each other by the spiral body so that they are almost completely separated into paper pieces and gypsum powder.

螺旋体の第一部分の刃物が、同じ位相に揃わないように90度より若干大きい、好ましくは92.5度から95度の範囲のピッチで螺旋羽根に取り付けられることで、刃物が同時に廃石膏ボードを噛みこまずに順次噛みこむことで、回転中における破砕負荷を分散して均一化でき、比較的小さな電力で長時間にわたって繰り返し破砕も可能になる。92.5度から95度の範囲の刃物の取り付けピッチであれば、略一周すると10度から20度のずれが生じて同じ位相に揃うことが無く、また余り噛みこみ間隔が長くもならず、適切な間隔で刃物は順次廃石膏ボードを噛みこむことができる。   The blades of the first part of the spiral body are attached to the spiral blades at a pitch slightly larger than 90 degrees, preferably in the range of 92.5 degrees to 95 degrees so that they do not align with the same phase, so that the blades simultaneously dispose of the waste gypsum board. By sequentially biting without biting, the crushing load during rotation can be distributed and uniformed, and crushing can be repeated for a long time with relatively small power. If the mounting pitch of the blade is in the range of 92.5 degrees to 95 degrees, there will be no deviation from 10 degrees to 20 degrees in one round and the same phase will not be aligned, and the biting interval will not be too long. The blades can bite the waste gypsum board at appropriate intervals.

紙/粉末分離手段の回転体は、約10m/秒から約30m/秒の周速度で回転する複数の螺旋羽根によって廃石膏ボードの破片に比較的大きな遠心力を作用させることができ、スクリーンに衝突させて石膏の粉砕と紙片の分離を促進することができ、また衝突による小さな振動でスクリーンのスリットの詰まりを防ぐことができる。螺旋羽根は、交互に受け入れ口側と紙排出口側にずれて配置されると、受け入れ口側に寄った螺旋羽根によって受け入れ口から入ってくる破片と石膏粉末を筒状スクリーン内の奥にも取り込んで、受け入れ口側に多く滞留するのを防ぎ、効率的な粉砕と分離を行うことができる。また各螺旋羽根の複数の開口によって軽量化が計られると共に破片を解して事前に紙片から石膏粉末を分離することができる。突起も破片を解して事前に紙片から石膏粉末を分離することができる。   The rotating body of the paper / powder separation means can apply a relatively large centrifugal force to the waste gypsum board fragments by a plurality of spiral blades rotating at a peripheral speed of about 10 m / sec to about 30 m / sec, The impact can promote the crushing of the gypsum and the separation of the paper pieces, and the screen can be prevented from clogging with a small vibration caused by the impact. When the spiral blades are alternately shifted to the receiving port side and the paper discharge port side, the fragments and gypsum powder entering from the receiving port by the spiral blades approaching the receiving port side are also transferred to the back of the cylindrical screen. Taking in and preventing a large amount of stagnation on the receiving port side, efficient crushing and separation can be performed. Moreover, weight reduction is achieved by the plurality of openings of each spiral blade, and the gypsum powder can be separated from the paper piece in advance by breaking the fragments. Protrusions can also be broken up to separate the gypsum powder from the paper pieces in advance.

紙/粉末分離手段の石膏粉末の排出部は、スクリューコンベヤから構成されることで、紙搬送風による分離石膏粉末の舞い上がりを防いで、まとめて強制的に排出することができる。
また、前記投入口は、開閉可能な蓋を有し、該蓋の開閉をスイッチで検出して、該蓋の開放時には少なくとも前記破砕手段の運転を停止し、該蓋の閉鎖時に本リサイクル装置の運転が可能になるように構成されると、破砕作業中に破砕粉塵が作業場に立ちのぼるのを防ぐことができ、作業環境を良好に維持できる。
更に、 前記破砕手段の一対の螺旋体は、互いに干渉しないように離れて配置され、また各々個別の可逆転の駆動手段によって回転駆動され、所定の回転抵抗を受けると所定回転数だけ逆転できるように構成されることで、石膏ボード破片を螺旋体によって互いに擦りあわしてほぼ完全に紙片と石膏粉末とに分離している過程で、電気モータなどの駆動手段に過大な回転抵抗が掛かると駆動手段を逆転させて過大な回転抵抗を解除して、繰り返し破砕と擦りあわせを実行できる
The discharge part of the gypsum powder of the paper / powder separation means is constituted by a screw conveyor, so that the separation gypsum powder can be prevented from rising due to the paper conveying wind and can be forcibly discharged collectively.
Further, the charging port has a lid that can be opened and closed, and detects the opening and closing of the lid with a switch. When the lid is opened, the operation of at least the crushing means is stopped, and when the lid is closed, If it is configured to be operable, it is possible to prevent crushing dust from rising to the workplace during crushing work, and to maintain a favorable work environment.

(B) is a side view thereof, FIG. 4 is a partially enlarged view of a cylindrical screen of the paper / powder separation means of the recycling apparatus, and FIG. 5 is a perspective view of a rotating body of the paper / powder separation means of the recycling apparatus. It is.

図1から図5において、代表実施例の廃石膏ボードのリサイクル装置1は、投入口12から投入された紙付きの廃石膏ボードWを破砕する破砕部10と、破砕された廃石膏ボードWの破片及び石膏粉末を紙/粉末分離部30へ搬送する搬送部20と、搬送されてくる破片及び石膏粉末を紙片W1と石膏粉末W2とに分離する紙/粉末分離部30とから構成されている。   1 to 5, a recycling apparatus 1 for waste gypsum board according to a representative embodiment includes a crushing unit 10 that crushes waste gypsum board W with paper fed from an inlet 12, and a crushing waste gypsum board W. It comprises a transport unit 20 that transports the fragments and gypsum powder to the paper / powder separation unit 30, and a paper / powder separation unit 30 that separates the transported fragments and gypsum powder into paper pieces W1 and gypsum powder W2. .

破砕部10は、上部にホッパー形状の廃石膏ボード投入口12を有すると共に一方端部に排出口13を有した横長の筒状ケーシング11と、その内部に一対の間で上から下に噛み込む方向に回転駆動され、互いに干渉しないように隔設され、間で投入された廃石膏ボードWを約5cm平方程度の破片に破砕すると共に破片及び石膏粉末を排出口13に搬送する螺旋体14A、14Bと、該螺旋体を約20RPMで個別に回転駆動する減速機付きの可逆転ギヤードモータM1、M1'とを有している。石膏ボードを破砕して破片を互いに擦りあわしてほぼ完全に紙片と石膏粉末とに分離している過程で、モータM1,M1‘は過大な回転抵抗が掛かると過大電流検出器や過大トルク検出器によって例えば5回転ほど逆転して過大な回転抵抗を解除するようになっている。螺旋体14A、14Bの螺旋方向は、搬送手段も兼ねるように破片を排出口13に搬送するように選択されている。投入口12は、破砕作業中の粉塵の立ちのぼりを防ぐためにシリンダーCYによって開閉駆動される蓋12aを有し、該蓋12aの開閉をスイッチSWで検出して、該蓋の開放時には破砕部10の運転又は本リサイクル装置全体の運転を停止し、該蓋の閉鎖時に破砕部10の運転はもとより、本リサイクル装置1の全体の運転が可能になる。   The crushing unit 10 has a horizontally long cylindrical casing 11 having a hopper-shaped waste gypsum board inlet 12 at the top and a discharge port 13 at one end, and a pair of bites into the inside thereof from above to below. Spirals 14A and 14B that are rotationally driven in the direction and spaced apart so as not to interfere with each other, crush the waste gypsum board W inserted between them into pieces of about 5 cm square and convey the pieces and gypsum powder to the discharge port 13. And reversible geared motors M1 and M1 ′ with reduction gears that individually rotate and drive the helical body at about 20 RPM. In the process of crushing the gypsum board and rubbing the pieces together and separating them almost completely into paper pieces and gypsum powder, the motors M1 and M1 'are overcurrent detectors and overtorque detectors when excessive rotational resistance is applied. Therefore, for example, the rotation resistance is reversed by about 5 rotations to release excessive rotation resistance. The spiral direction of the spiral bodies 14A and 14B is selected so as to transport the debris to the discharge port 13 so as to also serve as a transport means. The inlet 12 has a lid 12a that is opened and closed by a cylinder CY to prevent dust from rising during the crushing operation. The opening and closing of the lid 12a is detected by a switch SW, and when the lid is opened, the crushing unit 10 Or the entire recycling apparatus 1 is stopped, and the entire recycling apparatus 1 can be operated as well as the crushing unit 10 when the lid is closed.

筒状ケーシング11は、その内面に長手方向に延びた複数の条材11aを周方向に固定刃として隔設した第一部Aと、下流側の内面に内側に突出した櫛歯11bを長手方向に複数固定刃として隔設した第二部Bと、更に下流側に設けられて第一部Aと第二部Bで破砕されて生じた破片及び石膏粉末を収集する第三部Cとから構成されている。他方で、螺旋体14A,14Bは、筒状ケーシングの第一部Aに対応してそこの条材固定刃11aと干渉しないように周囲に複数の平刃や剣先刃の刃物15を突設した第一部分A‘と、筒状ケーシングの第二部Bに対応してそこの櫛歯固定刃11bと干渉しないように螺旋羽根16を有した第二部分B’と、筒状ケーシングの第三部Cに対応し、固定刃も螺旋羽根も無い軸17のみの第三部分C‘とから構成されている。筒状ケーシングの第三部Cは、第二部Bとの連通開口部11cに錘19aによって閉じるように付勢され、破片が楽に第二部Bから流入して来ないようにして第一部A及び第二部Bで繰り返し粉砕されると共に破片が互いに擦りあって紙と石膏粉とが効果的に分離できるようにする揺動可能な邪魔板19bを内部に有している。螺旋体の第一部分A’の刃物15は、同じ位相に揃わないように90度よりも若干大きいピッチで、好ましくは92.5度から95度の範囲のピッチで螺旋羽根16に取り付けられている。図2(c)に示すように刃物15のピッチを93.5度にすることで左右の螺旋体14A,14Bの対応位相の刃物15はスムーズに互いに中間側に寄ってきて石膏ボードを順次互いの間に噛みこむようになる。   The cylindrical casing 11 includes a first part A having a plurality of strips 11a extending in the longitudinal direction on the inner surface thereof as a fixed blade in the circumferential direction, and comb teeth 11b projecting inwardly on the inner surface on the downstream side in the longitudinal direction. A second part B spaced apart as a plurality of fixed blades, and a third part C that is provided further downstream and collects fragments and gypsum powders crushed by the first part A and the second part B Has been. On the other hand, the spiral bodies 14A and 14B correspond to the first part A of the cylindrical casing, and a plurality of flat blades and blades 15 of a sword blade are provided so as not to interfere with the strip fixing blade 11a there. A part A ′, a second part B ′ having a spiral blade 16 so as not to interfere with the comb fixed blade 11b corresponding to the second part B of the cylindrical casing, and a third part C of the cylindrical casing And a third portion C ′ having only a shaft 17 having neither a fixed blade nor a spiral blade. The third part C of the cylindrical casing is urged so as to be closed by the weight 19a to the communication opening part 11c with the second part B, and the first part prevents the fragments from easily flowing from the second part B. It has a rockable baffle 19b inside that is repeatedly crushed at A and second part B and allows the pieces to rub against each other to effectively separate the paper and gypsum powder. The blades 15 of the first part A 'of the spiral body are attached to the spiral blades 16 at a pitch slightly larger than 90 degrees, preferably at a pitch in the range of 92.5 degrees to 95 degrees so as not to align with the same phase. As shown in FIG. 2 (c), by setting the pitch of the blades 15 to 93.5 degrees, the blades 15 having the corresponding phases of the left and right spiral bodies 14A and 14B smoothly approach each other, and the gypsum boards are sequentially moved to each other. I get bitten in between.

搬送部20には、破砕部10の螺旋体14A、14Bも含まれ、他に破砕部10の横長の筒状ケーシングの排出口13に受け入れ口22を接続すると共に紙/粉末分離部30の統合された筒状ケーシング31及び円筒状スクリーン35用の受け入れ口32に破片及び石膏粉末を搬送するスクリューコンベヤ21と、該スクリューコンベヤの回転駆動モータM2とが含まれる。本実施例では、コンベヤ5による廃石膏ボードWの投入を容易にするように破砕部10を低く設置しているために低くなっている受け入れ口22から、分離した石膏粉末W2の袋詰めやトラック積み込みを楽にするように高く設置されているために高くなっている紙/粉末分離部30の受け入れ口32にかけてスクリューコンベヤ21は斜めに設置されている。 The conveyance unit 20 also includes the spiral bodies 14A and 14B of the crushing unit 10, and in addition to connecting the receiving port 22 to the discharge port 13 of the horizontally long cylindrical casing of the crushing unit 10, the paper / powder separation unit 30 is integrated. A screw conveyor 21 for transporting debris and gypsum powder to the cylindrical casing 31 and the receiving port 32 for the cylindrical screen 35, and a rotational drive motor M2 of the screw conveyor are included. In this embodiment, the gypsum powder W2 is separated from the receiving port 22 which is low because the crushing portion 10 is set low so that the waste gypsum board W can be easily fed by the conveyor 5, and the truck The screw conveyor 21 is installed obliquely over the receiving port 32 of the paper / powder separation unit 30 which is high because it is set high so as to facilitate loading.

紙/粉末分離部30は、外部の横長筒状ケーシング31と、その内部に間隔をとって固定状態で収容された内部の円筒状スクリーン35と、その内部で回転駆動される分離回転体40と、その回転駆動モータM3と、外部の横長筒状ケーシング31の下部の石膏粉末排出用スクリューコンベヤ38と、その回転駆動モータM4とを有している。外部の横長筒状ケーシング31及び円筒状スクリーン35は、内部点検ができるように上半分を開閉可能に構成されており、また搬送されて来る破片及び石膏粉末の受け入れ口32を一端部に有すると共に他方端部に紙片排出口33を有し、下部に石膏粉末の排出部としてのスクリューコンベヤ38を有している。この外部の筒状ケーシング31内に間隔をとって両端で固定されて収容された円筒状スクリーン35は、一端部に前記の一体的に統合された破片及び石膏粉末の受け入れ口32を有すると共に他方端に前記の一体的に統合された紙片排出口33を有し、1.4mm幅で10cm長さの細長いスリット37を周囲壁36に多数長手方向及び周囲方向に形成している。スリット37は、スクリーン周壁を形成すると共に先端をスクリーン外側に向けた楔状横断面の隣接した多数の横長の棧36の間に形成されており、ぶつかって来る紙片の排出を阻止して石膏粉の外側への排出を促進できるようにしており、詰まり防止構造になっている。乾燥した石膏粉は詰まることがないが、湿度が高くて湿り気がある場合にスリット37に一時的に詰まっても、横長のために次々とぶつかってくる粉末によってどこかが部分的に崩落し、その後は直ぐに詰りの全体が崩落することになる。棧36は、長手方向において、10cm間隔で補強用リング35Aで補強され仕切られている。ケーシング31とスクリーン35との間の間隔は、スリット37から分離されて出てくる石膏粉末を収集する空間を形成している。スリット37は、横長の他に斜めや、周囲方向にも長く形成される。   The paper / powder separation unit 30 includes an external horizontally long cylindrical casing 31, an internal cylindrical screen 35 accommodated in a fixed state with a space therebetween, and a separation rotator 40 that is rotationally driven therein. The rotary drive motor M3, the gypsum powder discharging screw conveyor 38 at the bottom of the external horizontally long cylindrical casing 31, and the rotary drive motor M4 are provided. The external horizontally long cylindrical casing 31 and the cylindrical screen 35 are configured so that the upper half can be opened and closed so that the inside can be inspected, and has a receiving port 32 for fragments and gypsum powder to be conveyed at one end. A paper piece discharge port 33 is provided at the other end portion, and a screw conveyor 38 as a discharge portion for gypsum powder is provided at the lower portion. A cylindrical screen 35 fixed and accommodated at both ends within the outer cylindrical casing 31 has the above-mentioned integrally integrated piece and gypsum powder receiving port 32 at one end and the other. A plurality of elongated slits 37 having a width of 1.4 mm and a length of 10 cm are formed in the peripheral wall 36 in the longitudinal direction and the circumferential direction. The slit 37 forms a peripheral wall of the screen and is formed between a plurality of adjacent horizontally long ridges 36 having a wedge-shaped cross section with the front end facing the outside of the screen. The discharge to the outside can be promoted, and it has a clogging prevention structure. Dried gypsum powder does not clog, but even if it is clogged up in a slit 37 when the humidity is high and damp, some parts collapse by the powder that hits one after another because of the landscape, Immediately after that, the whole clogging will collapse. The eaves 36 are reinforced and partitioned by a reinforcing ring 35A at intervals of 10 cm in the longitudinal direction. The space between the casing 31 and the screen 35 forms a space for collecting gypsum powder separated from the slit 37 and coming out. The slit 37 is formed to be long in the oblique direction and the peripheral direction in addition to the horizontally long shape.

分離回転体40は、円筒状スクリーン35内に回転可能に軸承され、受け入れ口32から紙排出口33へ紙片搬送風を発生する4枚の螺旋羽根42、44と、それらの外辺縁部に取り付けられたゴム板45とを有している。4枚の螺旋羽根の内の180度ピッチの2枚の螺旋羽根42は受け入れ口側に寄っており、また他の180度ピッチの2枚の螺旋羽根44は、紙排出口側に寄っている。回転駆動の可変速モータM3は、約10m/秒から約30m/秒の周速度で、好ましくは15m/秒の周速度で螺旋羽根42、44を回転駆動し、スクリーン35内で分離した紙片を搬送する搬送風を発生させると共に、受け入れ口側に寄った螺旋羽根42が受け入れた破片及び石膏粉末を奥の紙片排出口側に搬送する方向に回転させる。螺旋羽根42、44によって加えられる遠心力によって破片及び石膏粉末は、円筒状スクリーン35の内側に当てられて更に破砕され、石膏粉末がスリット37を通してスクリーンの外に分離し行き、残った紙片が搬送風によって紙排出口33に搬送されて分離して行く。分離した石膏粉末W2は、そのまま外部の横長筒状ケーシング31の下部から落下排出させることもできるが、前記搬送風の影響で舞い上がるのを防ぐためにスクリューコンベヤ38でまとめて強制排出するようにしている。紙排出口側に寄っている螺旋羽根44の受け入れ口側には、受け入れた紙片と石膏粉末を撹拌して散らす散らし棒47と、それらを取り込む小さな三角羽根46が設けられている。   The separation rotator 40 is rotatably supported in the cylindrical screen 35, and generates four pieces of spiral blades 42 and 44 that generate a paper piece conveying wind from the receiving port 32 to the paper discharge port 33, and the outer peripheral edges thereof. And an attached rubber plate 45. Of the four spiral blades, two spiral blades 42 with a 180-degree pitch are close to the receiving port side, and the other two spiral blades 44 with a 180-degree pitch are close to the paper discharge port side. . The rotational speed variable speed motor M3 rotationally drives the spiral blades 42 and 44 at a peripheral speed of about 10 m / second to about 30 m / second, preferably at a peripheral speed of 15 m / second, and separates the pieces of paper separated in the screen 35. While the conveyance wind to convey is generated, it rotates in the direction which conveys the fragment and the gypsum powder which the spiral blade 42 which approached the receiving port side received to the back paper piece discharge port side. Debris and gypsum powder are applied to the inside of the cylindrical screen 35 by the centrifugal force applied by the spiral blades 42 and 44 and further crushed. The gypsum powder is separated from the screen through the slit 37, and the remaining paper pieces are conveyed. It is conveyed to the paper discharge port 33 by the wind and separated. The separated gypsum powder W2 can be dropped and discharged from the lower portion of the external horizontally long cylindrical casing 31 as it is. However, the screw conveyor 38 collectively forcibly discharges it to prevent it from rising due to the influence of the conveying wind. . On the receiving port side of the spiral blade 44 close to the paper discharge port side, there are provided a scattering rod 47 for stirring and scattering the received paper piece and gypsum powder, and a small triangular blade 46 for taking them in.

螺旋羽根42、44には、各々複数の開口43が形成されており、それら開口43によって軽量化が計られると共に破片を解して事前に紙片から石膏粉末を分離することができる。更に、突起も螺旋羽根に形成され、破片を解して事前に紙片から粉末を分離することができる。螺旋羽根の先端部に取り付けられたゴム板45は、万が一スクリーン35の内面に接触した場合にスクリーンを傷めないように防護するためのものである。   A plurality of openings 43 are formed in each of the spiral blades 42 and 44, and the weight can be reduced by the openings 43, and the gypsum powder can be separated from the paper pieces in advance by breaking the fragments. Furthermore, a protrusion is also formed on the spiral blade, and the powder can be separated from the paper piece in advance by breaking the piece. The rubber plate 45 attached to the tip of the spiral blade is for protecting the screen from being damaged if it contacts the inner surface of the screen 35.

前記代表実施例の廃石膏ボードのリサイクル装置1の他に、搬送手段のスクリューコンベヤ21を省いて、破砕部10の排出口13と紙/粉末分離部30の受け入れ口32とをほぼ同じ高さにして、それらを直接接続した構成も採用できる。   In addition to the waste gypsum board recycling apparatus 1 of the above-described representative embodiment, the screw conveyor 21 of the conveying means is omitted, and the discharge port 13 of the crushing unit 10 and the receiving port 32 of the paper / powder separation unit 30 are substantially the same height. Thus, a configuration in which they are directly connected can also be adopted.
