The lid 6 is equipped with a lever 11 pressing the lid against the discharge port. A reference weight 12 is hanged by a wire rope 15 connected to the lever 11 so that the pressing lid 6 is pressed against the discharge port 7 with a minimum required pressing force. An additional weight 16 hanged by a wire rope 18 similarly gives a pressing force required for dehydration. When the screw 3 becomes overloaded, a lifter 19 lifts the additional weight 16 to eliminate the pressing force by the weight 16, so that the pressing force of the pressing lid 6 is rapidly reduced and the garbage solidified at the discharge port 7 is discharged. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【発明の属する技術分野】
本発明は、厨房などから排出される生ゴミを圧縮して脱水処理するスクリュープレス式の脱水機にいて、生ゴミによるスクリーン筒の排出口の詰まりを直ちに解消させるようにした構成に関する。
【0002】
【従来の技術】
厨房から排出される生ゴミを脱水して固形化するためにスクリュー脱水機が用
いられているが、このようなスクリュー脱水機は、たとえば、
【特許文献1】実公昭57−42640号に示されているように、多数の脱水孔を設けたスクリーン筒の内側にスクリューを設け、スクリーン筒の開口部にヒンジで取り付けられた押し蓋をそなえ、この押し蓋に取り付けたレバーを引張りばねで引っ張ることにより開口部に押し付けるようにしている。
また、キャベツやごぼうなどの強い繊維質が混入されている生ゴミが、排出口付近で固まって排出されなくなる場合があり、このため、
【特許文献2】特開平10−34387号では、押し蓋を軸方向に移動する円錐形にし、生ゴミが排出口で固まった場合に、軸方向に移動させることによって、排出口との間隙を大きくするとともに、押し蓋をスクリューの回転方向に回転させて固まった生ゴミを排出させるスクリュー脱水機が提案されている。
【0003】
なお、
【特許文献3】特開平11−104504号には、スクリューフィーダで精白ロールに送られる玄米を精白する精米機において、精白室の流出口を塞ぐ抵抗板をリンクの一方端に取り付け、リンクの他方端は引張りばねを介してリニアヘッドに接続され、リニアヘッドによる引張りばねの調整で、抵抗板の押し付け力を調整するものが示されている。
【0004】
【発明が解決しようとする課題】
このように、スクリューをそなえたスクリーン筒の排出口を塞ぐ押し蓋は、軸方向に移動させるか、引張りばねによって排出口に押し付けるようにしており、生ゴミに含まれている繊維質などで処理物がスクリーン筒内の排出口付近で固まって排出できない場合は、押し蓋を軸方向に移動させたり、引張りばねの引っ張り長さを調整し、押し付け力を弱めて押し蓋を開かせるようにしている。
【0005】
このため、生ゴミの固まりを生じたときは、スクリューを駆動する電動機の過負荷を検出した信号により、押し蓋を軸方向に移動させ、あるいは、引張りばねの支持位置を移動させて引っ張り長さを調整して、押さえ蓋の押し付け力が次第に弱くなるようにしており、押し蓋を大きく開かせるための動作時間が長く、その間に排出口の固まりが進行して押し蓋をさらに大きく開かせる必要があり、固まった生ゴミを排出する時間も長くなっている。
また、このように長くなる時間を考慮して、早めに過負荷状態の信号を出すようにすると、過負荷と判断されるときの押し蓋の圧縮力が低下するので十分な圧縮脱水が行われなくなる欠点が生じる。
【0006】
本発明は、このような点にかんがみ、過負荷の検出により急速に押し蓋の押し付け力を低下させ、固まりを排出させるスクリュー脱水機を提供することを目的としている。
【0007】
【課題を解決するための手段】
このため、生ゴミを移送するスクリューを囲んで、多数の脱水孔をそなえたスクリーン筒と、スクリーン筒の排出口にヒンジで取り付けた押さえ蓋と、この押さえ蓋のヒンジ側に一方端を取り付けたレバーを設け、前記レバーの他方端に連結した索条を介して基準重りと付加重りを吊持させて押さえ蓋を排出口に押し付けるようにし、スクリューの過負荷信号により前記付加重りを持ち上げるリフターをそなえており、過負荷信号によって付加重りによる押し付け力を急速に除くとともに、押さえ蓋の押し付け力を必要な最小限に保持させ、固まった生ゴミを急速かつ円滑に排出できるようにしている。
【0008】
【発明の実施の形態】
これを図1に示す実施例について説明する。
図において、1は機枠、2は機枠内に設置されたスクリュー脱水機の外筒、3は外筒2内のスクリューでモータ4によって回転駆動される。5はスクリュー3を囲むスクリーン筒で多数の脱水孔をそなえている。6はスクリーン筒5の排出口7にヒンジ8で取り付けた押さえ蓋、9は生ゴミの供給口、10は排水口、11は押さえ蓋6のヒンジ8側に取り付け押さえ蓋を操作するレバーである。
12は、押さえ蓋6に最小限必要な押し付け力を加えるための基準重りで、滑車13、14を介して前記レバー11の端部に連結した索条15、たとえばワイヤ、ロープなどにより吊持されている。16は、基準重り12と協同して押さえ蓋6にスクリュー3による圧縮に必要な押し付け力を加える付加重りで、滑車13、17を介して前記レバー11の端部に連結した索条18により吊持されている。19は機枠1に取り付けられ、前記付加重り16を持ち上げるリフターで、付加重り16と僅かな間隙で設けている。20はスクリュー3の過負荷状態をモータ4で検出する制御器で、リフター19に過負荷信号21を送出する。
【0009】
供給口9からスクリーン筒5内に生ゴミが供給されると、モータ4で回転するスクリュー3により排出口7に向かって移送され、押さえ蓋6に押し付けられて脱水される。脱水処理された生ゴミは、スクリュー3による移送力で押さえ蓋6の押し付け力に抗して押さえ蓋を押し上げて排出シュートに排出される。
しかし、キャベツやごぼうなどの強い繊維質の生ゴミが混入されていると、切断されない長い繊維質がスクリーン筒5内で絡み合ったり、スクリーン筒の脱水孔に絡んで固まりを生じ、スクリュー3による移送が困難になり押さえ蓋6を押し上げられずに排出が阻止される場合がある。
このような状態になるとモータ4が過負荷になり、制御器20から過負荷信号21がリフター19に送出され、リフター19は付加重り16を持ち上げる。このため、付加重り16によりレバー11に加わる引っ張り力が急速に無くなり、押さえ蓋6は基準重り15による引っ張り力だけの押し付け力になり、スクリュー3の移送力で直ちに押さえ蓋6が大きく開かれ、スクリーン筒5内で固まった生ゴミの固形物を排出させる。
なお、押さえ蓋6の保持に必要な最小限の押し付け力は、基準重り12で保持され、固まった生ゴミが排出されると、過負荷信号21がなくなり、リフター19が下降して付加重り16の引っ張り力がレバー11に加えられる。
【0010】
図2、図3は、基準重り12と付加重り16の別の態様を示すもので、索条15に吊持された基準重り12に、吊持方向の長孔22を設け、この長孔22に挿通した横軸23に付加重り16を固着させ、横軸23が長孔22の下端に接触した状態で付加重り16が加えられており、過負荷信号によりリフター19が付加重り16を押し上げると、横軸23が長孔22内を上昇して索条15には基準重り12の重量だけが加わり、押さえ蓋の押し付け力を減じさせる。
【0011】
【発明の効果】
本発明は、生ゴミを移送するスクリューを囲んで、多数の脱水孔をそなえたスクリーン筒と、スクリーン筒の排出口にヒンジで取り付けた押さえ蓋と、この押さえ蓋のヒンジ側に一方端を取り付けたレバーをそなえたスクリュー脱水機において、前記レバーの他方端に連結した索条を介して、押さえ蓋を排出口に押し付けるようにした基準重りと付加重りが吊持されており、スクリューの過負荷信号により前記付加重りを持ち上げるリフターをそなえているので、繊維質の生ゴミなどがスクリーン筒の排出口側で固まり、スクリューが過負荷状態になったときは、リフターが付加重りを持ち上げて押さえ蓋の押し付け力を急速に減少させ、押さえ蓋を容易に開かせ、固まった生ゴミを円滑に排出させ得る効果があり、押さえ蓋に常に必要とする最小限の押し付け力は、基準重りによって過負荷排出時も保持される。
【0012】
なお、過負荷を生じさせる生ゴミは、過負荷信号が送出されると、急速に押さえ蓋が開かれて排出されるので、固まった生ゴミが排出口付近に滞留することがなく、過負荷状態の進行を防ぐことができる。また、押さえ蓋に必要な最小限の押し付け力は、基準重りで保持されるため脱水機の性能を低下させず、効率の良い脱水処理を行うことができる。
また、基準重りと付加重りは、それぞれ別個の索条に吊持させてもよく、基準重りに長孔を設けて付加重りを長孔に通した横軸で保持させるようにすれば、両方の重りをまとめて吊持させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a screw press-type dehydrator for compressing and dewatering garbage discharged from a kitchen or the like, and relates to a configuration in which clogging of a discharge port of a screen cylinder due to garbage is immediately eliminated.
[0002]
[Prior art]
A screw dehydrator is used to dewater and solidify garbage discharged from the kitchen.
[Patent Document 1] As shown in Japanese Utility Model Publication No. 57-42640, a screw is provided inside a screen cylinder provided with a large number of dehydration holes, and a push lid attached by a hinge to an opening of the screen cylinder is provided. The lever attached to the push lid is pulled by an extension spring and pressed against the opening.
In addition, garbage mixed with strong fibrous materials such as cabbage and burdock may solidify near the discharge port and become unable to be discharged.
[Patent Document 2] Japanese Patent Application Laid-Open No. 10-34387 discloses that the pressing lid is formed in a conical shape that moves in the axial direction, and when the garbage is solidified at the discharge port, the garbage is moved in the axial direction to thereby reduce the gap with the discharge port. A screw dehydrator that increases the size and rotates the push lid in the rotation direction of the screw to discharge the solidified garbage has been proposed.
[0003]
In addition,
[Patent Document 3] Japanese Patent Application Laid-Open No. 11-104504 discloses a rice mill for polishing brown rice sent to a milling roll by a screw feeder, in which a resistance plate for closing an outlet of a milling chamber is attached to one end of a link and the other end of the link. The end is connected to a linear head via a tension spring, and the adjustment of the tension spring by the linear head adjusts the pressing force of the resistance plate.
[0004]
[Problems to be solved by the invention]
In this way, the push lid that closes the discharge port of the screen cylinder with the screw is moved in the axial direction or pressed against the discharge port by a tension spring, and treated with the fiber contained in garbage. If the object hardens near the discharge port in the screen cylinder and cannot be discharged, move the push lid in the axial direction or adjust the tension length of the tension spring to weaken the pressing force and open the push lid. I have.
[0005]
For this reason, when a lump of garbage is generated, the push lid is moved in the axial direction or the supporting position of the tension spring is moved by the signal that detects the overload of the motor driving the screw, and the tension length is increased. Is adjusted so that the pressing force of the holding lid gradually weakens, and the operation time for opening the pressing lid widely is long, and during that time, the discharge port advances and the pressing lid needs to be opened further. There is a longer time to discharge the solid garbage.
In addition, if the signal of the overload state is output early in consideration of such a long time, the compression force of the push lid when the overload is determined is reduced, so that sufficient compression dehydration is performed. There is a disadvantage that disappears.
[0006]
In view of such a point, an object of the present invention is to provide a screw dehydrator which rapidly reduces the pressing force of a push lid by detecting overload and discharges a lump.
[0007]
[Means for Solving the Problems]
For this reason, a screen cylinder provided with a large number of dehydration holes, a holding lid attached to a discharge port of the screen cylinder with a hinge, and one end attached to the hinge side of the holding lid are provided around the screw for transferring the garbage. A lever is provided, a reference weight and an additional weight are hung via a cable connected to the other end of the lever to press the holding lid against the discharge port, and a lifter that lifts the additional weight by an overload signal of a screw. With the overload signal, the pressing force due to the additional weight is rapidly removed by the overload signal, and the pressing force of the holding lid is kept to a necessary minimum so that the solid garbage can be quickly and smoothly discharged.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
This will be described with reference to the embodiment shown in FIG.
In the figure, 1 is a machine frame, 2 is an outer cylinder of a screw dehydrator installed in the machine frame, and 3 is a screw in the outer cylinder 2 which is driven to rotate by a motor 4. Reference numeral 5 denotes a screen cylinder surrounding the screw 3 and having a number of dehydration holes. Reference numeral 6 denotes a holding lid attached to the discharge port 7 of the screen cylinder 5 with a hinge 8, reference numeral 9 denotes a garbage supply port, reference numeral 10 denotes a drain port, and reference numeral 11 denotes a lever attached to the holding lid 6 on the hinge 8 side to operate the holding lid. .
Reference numeral 12 is a reference weight for applying a minimum necessary pressing force to the holding lid 6, and is suspended by a rope 15, such as a wire or a rope, connected to the end of the lever 11 via pulleys 13, 14. ing. Reference numeral 16 denotes an additional weight for applying a pressing force required for compression by the screw 3 to the holding lid 6 in cooperation with the reference weight 12, and is suspended by a cable 18 connected to the end of the lever 11 via pulleys 13 and 17. Is held. A lifter 19 is attached to the machine frame 1 and lifts the additional weight 16, which is provided with a slight gap from the additional weight 16. Reference numeral 20 denotes a controller for detecting an overload state of the screw 3 by the motor 4, and sends an overload signal 21 to the lifter 19.
[0009]
When the garbage is supplied from the supply port 9 into the screen cylinder 5, the garbage is transferred toward the discharge port 7 by the screw 3 rotated by the motor 4, pressed against the holding lid 6, and dewatered. The dewatered garbage is pushed up by the holding lid against the pressing force of the holding lid 6 by the transfer force of the screw 3 and discharged to the discharge chute.
However, if strong fibrous garbage such as cabbage or burdock is mixed in, long fibers that are not cut are entangled in the screen cylinder 5 or entangled in the dewatering holes of the screen cylinder to form a lump, and are transported by the screw 3. In some cases, it is difficult to push up the holding lid 6 to prevent discharge.
In such a state, the motor 4 is overloaded, an overload signal 21 is sent from the controller 20 to the lifter 19, and the lifter 19 raises the additional weight 16. For this reason, the pulling force applied to the lever 11 by the additional weight 16 rapidly disappears, the pressing force of the pressing lid 6 becomes only the pulling force of the reference weight 15, and the pressing force of the screw 3 immediately opens the pressing lid 6 greatly. The solid garbage solidified in the screen cylinder 5 is discharged.
The minimum pressing force required for holding the holding lid 6 is held by the reference weight 12, and when the solidified garbage is discharged, the overload signal 21 disappears, the lifter 19 descends, and the additional weight 16 Is applied to the lever 11.
[0010]
2 and 3 show another embodiment of the reference weight 12 and the additional weight 16. The reference weight 12 suspended on the cable 15 is provided with a long hole 22 in the hanging direction. The additional weight 16 is fixed to the horizontal shaft 23 inserted through the lower hole, and the additional weight 16 is added in a state where the horizontal shaft 23 is in contact with the lower end of the elongated hole 22. When the lifter 19 pushes up the additional weight 16 by an overload signal. Then, the horizontal axis 23 rises in the elongated hole 22 and only the weight of the reference weight 12 is applied to the cable 15 to reduce the pressing force of the holding lid.
[0011]
【The invention's effect】
The present invention provides a screen cylinder having a number of dewatering holes surrounding a screw for transferring garbage, a holding lid attached to a discharge opening of the screen cylinder with a hinge, and one end attached to the hinge side of the holding lid. In a screw dehydrator equipped with a lever, a reference weight and an additional weight, which press the holding lid against the discharge port, are suspended via a cable connected to the other end of the lever, and the screw is overloaded. Since a lifter that lifts the additional weight by a signal is provided, fibrous garbage and the like solidify on the discharge port side of the screen cylinder, and when the screw is overloaded, the lifter lifts the additional weight and presses down the cover. Has the effect of rapidly reducing the pressing force of the hood, opening the holding lid easily, and smoothly discharging solidified garbage. Minimum pressing force, overload emissions also held by the reference weight.
[0012]
When the overload signal is sent, the garbage that causes overload is quickly opened and ejected, so that the solid garbage does not stay in the vicinity of the discharge port. The progress of the state can be prevented. In addition, since the minimum pressing force required for the holding lid is held by the reference weight, the performance of the dehydrator is not reduced and efficient dehydration can be performed.
In addition, the reference weight and the additional weight may be suspended from separate ropes, respectively.If the reference weight is provided with a long hole and the additional weight is held by the horizontal axis passing through the long hole, both of the two weights may be used. Weights can be suspended together.
