Description

【0001】
【産業上の利用分野】
本発明はライスセンタやカントリエレベータなどの穀物乾燥調製施設における湿式集塵装置に関する。
【0002】
【従来の技術】
従来、この種の穀物乾燥調製施設においては、荷受工程から出荷工程までに発生する大量の粉塵を回収するため、各工程に設置した種々の処理機器及び搬送機器に接続した集塵ダクトを、屋外に設置した湿式の集塵装置に集中的に配管して効率的に集塵を行っている(特開平4−22440等参照)。
【0003】
この集塵装置を図4に基づいて説明する。水槽101の上方を除塵室102となすとともに除塵室102の上部にシャワー管103を配設し、除塵室の下部一側に含塵空気取入口104を、除塵室102の上端に清浄空気排出口105を各々設け、水槽101内には汚泥コンベア(スラッジコンベア)106を設けるとともに除塵室102下端には粗大粉塵コンベア(リッターコンベア)107を設けてあり、除塵室102内に供給される含塵空気とシャワー水とを接触させて除塵し、粗大粉塵は粗大粉塵コンベア107によって排出され、水槽101中に沈んだ微粉塵や土(汚泥)は汚泥コンベア106によって取り出すように形成されている。
【0004】
【発明が解決しようとする課題】
ところで、前記汚泥コンベア106だけでは水槽101中の全ての微粉塵や汚泥を搬出することは困難であり、水槽101内に残留する微粉塵や汚泥が腐敗して悪臭を発し、不衛生である。すなわち、除塵室102内に供給される含塵空気のうち、水槽101中に流入する微粉塵は、比較的比重の大きい粉塵と比重の小さい粉塵とに分離する。そして、比重の大きい粉塵は水槽101の底部に汚泥として堆積し、汚泥コンベア106によって機外へ取り出される。しかし、比重の小さい粉塵は水槽101の水面上に浮遊しているため、機外に取り出されることはなかった。このため、従来は籾の収穫期終了後に浮遊粉塵を撤去したり、収穫期中であれば掻き寄せ棒などを使って人力で浮遊粉塵を機外に撤去していた。
【0005】
本発明は前記問題点にかんがみ、水槽の水面上に浮遊している粉塵を回収して、悪臭を生じることがない湿式集塵装置を提供することを技術的課題とする。
【0006】
【課題を解決するための手段】
前記課題を解決するため本発明は、底部に水槽を、その上方に、含塵空気取入口と清浄空気排出口を設けた除塵室を各々形成し、該除塵室上部には前記水槽に連絡したシャワー水供給装置を配設し、該シャワー水供給装置により粉塵を吸着した水が前記水槽に落下するように形成した穀物乾燥調製施設における湿式集塵装置において、前記水槽の水面より上方にあって前記除塵室に流入する粗大粉塵を搬送する粗大粉塵コンベアを横設するとともに、前記水槽の底部には該水槽に沈殿した汚泥を搬送する汚泥コンベアを横設する一方、前記水槽の水面付近には該水槽を浮遊する微粉塵を回収すべく、一部がスクリーン状の水切りとなした複数のバケットからなる浮遊粉塵回収コンベアを横設する、という技術的手段を講じた。
【0007】
【0008】
【0009】
【作用】
穀物乾燥調製施設から集塵室に送り込まれた粉塵は、シャワー水供給装置から噴出する水滴又は霧滴に吸着され、汚水となって集塵室下方に落下する。そして、集塵室下方の粗大粉塵コンベアに到達した汚水は粗大な粉塵だけがこのコンベアによって機外に排出されるが、その他の汚水は粗大な粉塵だけがこのコンベアによって機外に排出されるが、その他の排水はコンベアを通過して水槽へ落下する。水槽内へ落下した汚水は水槽内で比重の大きい粉塵と比重の小さい粉塵とに分離し、比重の大きい粉塵は水槽の底部に汚泥として沈殿し、汚泥コンベアが回動することにより機外に排出される。一方、比重の小さい粉塵は水面上を浮遊するが、ポンプによる水流により浮遊粉塵回収コンベア付近に引き寄せられる。そして比重の小さい粉塵は浮遊粉塵回収コンベアに設けられ、一部がスクリーン状の水切りとなしたバケットが回動することにより水槽から掻き上げられ、その後前記汚泥コンベアに供給されて機外に排出される。このとき、バケットは一部がスクリーン状の水切りとなっており、水槽の水を掻き出すことなくほぼ完全に浮遊粉塵の回収が行われる。以上のように、水槽の水面上を浮遊する微粉塵を常時回収することができる。
【0010】
【実施例】
次に、本発明の好適な実施例を図面に基づいて説明する。図1は集塵装置の内部を示す概略側断面図であり、図2は概略正断面図である。図1及び図2において湿式集塵装置1は底部に水槽2を、その上方に、除塵室3を形成している。除塵室3は上部に前記水槽2に連絡するシャワー水供給装置4を配設し、除塵室3の一側の壁部には、乾燥機、籾摺機等の穀物乾燥調製施設に連通するダクト5が連結されており、穀物乾燥調製施設からこのダクト5を通して粉塵が含塵空気取入口6に送り込まれる。符号7は特開平6−47229号に開示される水幕形成装置であり、該装置により含塵空気取入口6に送給された含塵空気がカーテン状の水幕に直ちに捕捉され、含塵空気の拡散を最小限に抑えることができる。
【0011】
除塵室3の底部には、漏斗状の流下樋8が設けられ、該流下樋8の底部には粃(しいな)、藁(わら)くず等の比較的大きな夾雑物を搬送するリッターコンベア9が設けられる。該リッターコンベア8は環状の無端コンベアであって、搬送始端側のロール10、搬送終端側のロール11及びモータ等が内蔵されたコンベア駆動装置12により回動される。そして、リッターコンベア9には粃、藁くず等をかき出す複数のかき上げ片13を等ピッチをおいて設け、リッターコンベア9の側面と底面とにはコンベアケース14を設けている。該コンベアケース14の底面は、粃、藁くず等が漏出しない網目状のスクリーンになっており、粃、藁くず以外の汚水が水槽2に落下することができる。
【0012】
水槽2は底部が漏斗状になっており、水槽2の水面付近で、かつ水槽2の幅方向中央部(図2参照)には、水面を浮遊する比重の小さい微粉塵(例えば籾殻の芒等)を回収する浮遊粉塵回収コンベア15が横設されている。該コンベア15は環状の無端コンベアであって、搬送始端側のロール16、搬送終端側のロール17及び図示しない駆動装置により回動される。そして、浮遊粉塵回収コンベア15には水面上を浮遊する微粉塵を回収する複数のバケット18を等ピッチをおいて設け、コンベア15の搬送終端側は受樋21を介して後述するスラッジコンベア22と接続している。前記バケット18の開口部19は傾斜状に設けられており(図3参照)、開口部と反対側の回収部20は浮遊粉塵が漏出しない網目状のスクリーンとなっている。
【0013】
前記漏斗状の水槽2の底部には、水槽2に沈殿する汚泥をかき出すスラッジコンベア22を横設している。該コンベア22も環状の無端コンベアであって、搬送始端側のロール23、搬送終端側のロール24及びモータ等が内蔵されたコンベア駆動装置25により回動される。符号26は汚泥をかき出すかき上げ片であり、符号27はコンベアケースである。該コンベアケース27には前記受樋21を設けて、浮遊粉塵回収コンベア15と接続している。
【0014】
前記水槽2の一側にはポンプ吸水管28を設け、該ポンプ吸水管28は前記水槽2の幅方向において、前記リッターコンベア9と対向する位置に設けている。そして、前記リッターコンベア9のコンベアケース14から漏出した汚水が水面上で浮遊粉塵となり、該浮遊粉塵が浮遊粉塵回収コンベア15に回収されるよう、水槽2の水面に幅方向(図2では左から右)の水流を形成する。さらに、水槽2の一側には、補給水装置35とオーバーフロー36とを設けている。
【0015】
前記除塵室3の上部には多数の噴水口を有するシャワー水供給装置4が配設されているが、該シャワー水供給装置4にはポンプ吸水管28、ポンプ29及び取水管30を介して水槽2から給水が行われる。また、符号31は前記水幕形成装置7に給水する分岐管である。
【0016】
前記シャワー供給装置4の上方には、含塵空気と清浄空気とを分離する気水分離フィルタ32を設け、シャワー水供給装置4の下方には除塵室3内の圧力を一定に保つ圧力拡散板33を設けるとともに、網状のスクリーン34を設ける。
【0017】
以下、上記実施例における具体的作動について説明する。乾燥機、籾摺機等の穀物乾燥調製施設からダクト5及び含塵空気取入口6を介して集塵室3内に送り込まれた粉塵は、最初に水幕形成装置7の水幕によって直ちに捕捉され、次にシャワー水供給装置4から噴出する水滴又は霧滴に吸着されて汚水となる。そして、粉塵を吸着した汚水は、重力により除塵室3下部の流下樋8に落下し、流下樋8上を流下しながら、全ての汚水がリッターコンベア9に到達する。一方、除塵室3内で粉塵が除去された清浄空気は、気水分離フィルタ32により気水分離され、清浄空気排気口37から機外へ排出される。
【0018】
リッターコンベア9に到達した汚水は、汚水に含まれる粃、藁くず等の粗大な粉塵がこのコンベア7によって機外に排出される。しかし、シャワー水によって吸着されたその他の汚水はコンベア9及びコンベアケース13のスクリーンから水槽2に落下する。水槽2内へ落下した汚水は水槽2内で比重の大きい粉塵と比重の小さい粉塵とに分離する。すなわち、汚水の中で比重の大きな粉塵(土や泥など)は水槽2底部のコンベアケース27に汚泥として沈殿し、スラッジコンベア8が回動することにより、汚泥がかき上げ片26にかき出されて機外に排出される。一方、汚水の中で比重の小さな粉塵(籾がらの芒など)は水槽2底部に沈降することはなく、水槽2水面上を浮遊する。この時、ポンプ吸水管28により形成された水流により、比重の小さな粉塵は浮遊粉塵回収コンベア15付近に引き寄せられ、該コンベア15のバケット18が回動することにより、比重の小さい粉塵がかき上げられる。この時、バケット18の回収部20はスクリーン状の水切りとなり、水をかき出すことはない。そして、バケット18により比重の小さな粉塵は搬送終端部の受樋21まで移送され、スラッジコンベア22により比重の大きな粉塵(汚泥)とともに機外に排出される。
【0019】
【発明の効果】
以上のように本発明によれば、底部に水槽を、その上方に、含塵空気取入口と清浄空気排出口を設けた除塵室を各々形成し、該除塵室上部には前記水槽に連絡したシャワー水供給装置を配設し、該シャワー水供給装置により粉塵を吸着した水が前記水槽に落下するように形成した穀物乾燥調製施設における湿式集塵装置において、前記水槽の水面より上方にあって前記除塵室に流入する粗大粉塵を搬送する粗大粉塵コンベアを横設するとともに、前記水槽の底部には該水槽に沈殿した汚泥を搬送する汚泥コンベアを横設する一方、前記水槽の水面付近には該水槽を浮遊する微粉塵を回収すべく、一部がスクリーン状の水切りとなした複数のバケットからなる浮遊粉塵回収コンベアを横設したので、除塵室に流入する粗大粉塵及び水槽内に沈殿する汚泥を機外に搬送できるばかりか、水槽の水面上を浮遊する粉塵をも水槽の水を掻き出すことなくほぼ完全に回収することができるので、悪臭を発生することなく、衛生的である。さらに、従来のように、籾の収穫期終了後に浮遊粉塵を撤去したり、籾の収穫期途中に掻き寄せ棒などを使って人力で浮遊粉塵を機外に撤去する必要がなくなった。

Dust-containing air supplied into the dust removal chamber 102 is provided. And shower water to remove dust, coarse dust is discharged by a coarse dust conveyor 107, and fine dust and soil (sludge) sinking in the water tank 101 are taken out by a sludge conveyor 106.
[0004]
[Problems to be solved by the invention]
By the way, it is difficult to carry out all the fine dust and sludge in the water tank 101 only by the sludge conveyor 106, and the fine dust and sludge remaining in the water tank 101 rot and emit bad smell, which is unsanitary. That is, of the dust-containing air supplied into the dust removal chamber 102, the fine dust flowing into the water tank 101 is separated into dust having a relatively large specific gravity and dust having a relatively small specific gravity. Then, the dust having a large specific gravity accumulates as sludge on the bottom of the water tank 101 and is taken out of the machine by the sludge conveyor 106. However, since the dust having a small specific gravity is floating on the water surface of the water tank 101, it was not taken out of the machine. For this reason, conventionally, suspended dust was removed after the completion of the harvesting period of paddy, or during the harvesting period, suspended dust was manually removed using a scraper bar or the like.
[0005]
In view of the above problems, an object of the present invention is to provide a wet dust collector that collects dust floating on the water surface of a water tank and does not generate an odor.

In order to collect the fine dust floating in the water tank, a technical means of horizontally arranging a floating dust collection conveyor composed of a plurality of buckets partially screen-shaped drained was taken.
[0007]
[0008]
[0009]
[Action]
The dust sent from the grain drying preparation facility to the dust collection chamber is adsorbed by the water droplets or fog droplets ejected from the shower water supply device, becomes sewage, and falls below the dust collection chamber. The sewage that has reached the coarse dust conveyor below the dust collection chamber has only coarse dust discharged out of the machine by this conveyor, while other sewage has only coarse dust discharged out of the machine by this conveyor. , And other wastewater passes through a conveyor and falls into a water tank. The sewage that has fallen into the water tank is separated into dust having a high specific gravity and dust having a low specific gravity in the water tank, and the dust having a high specific gravity settles as sludge at the bottom of the water tank, and is discharged outside the machine by rotating the sludge conveyor. Is done. On the other hand, the dust having a low specific gravity floats on the water surface, but is attracted to the vicinity of the floating dust collection conveyor by the water flow of the pump. Then, a small dust specific gravity is provided on the floating dust collecting conveyor, partially bucket without a screen-like draining is scooped up from the water bath by rotating, it is then fed to the sludge conveyor discharged outside Is done.

Is discharged outside the machine. On the other hand, dust having a small specific gravity (such as ash of rice chaff) in the sewage does not settle at the bottom of the water tank 2 but floats on the water surface of the water tank 2. At this time, due to the water flow formed by the pump suction pipe 28, the dust having a small specific gravity is drawn to the vicinity of the floating dust collection conveyor 15, and the bucket 18 of the conveyor 15 is rotated, whereby the dust having the small specific gravity is scraped up. . At this time, the collecting section 20 of the bucket 18 becomes a screen-shaped drainer, and does not discharge water. Then, the dust having a small specific gravity is transported by the bucket 18 to the receiving gutter 21 at the terminal end of the conveyance, and is discharged outside the machine together with the dust (sludge) having the large specific gravity by the sludge conveyor 22.
