Japanese Patent Laid-Open No. 10-305298

しかし、前記特許文献1に記載の篩渣洗浄脱水装置では、以下のような問題がある。   However, the sieve cleaning and dehydrating apparatus described in Patent Document 1 has the following problems.

つまり、前記特許文献1に記載の篩渣洗浄脱水装置は、撹拌洗浄室、洗浄水排出室、スクリーン、スクリューコンベア、スクリーン式篩渣除去装置を一体形とした装置であるが、その撹拌洗浄室は、篩渣の攪拌を行うに十分な容積を確保する必要があり装置全体が大型となり、設備費が増大する。また、撹拌洗浄室の容積が大きいことより、使用する洗浄水の使用量が多く、また、その排水を処理する費用も嵩み、ランニングコストが増大する。   That is, the sieve cleaning and dewatering device described in Patent Document 1 is an apparatus in which a stirring cleaning chamber, a cleaning water discharge chamber, a screen, a screw conveyor, and a screen type sieve removing device are integrated. In this case, it is necessary to secure a sufficient volume for stirring the sieve, and the entire apparatus becomes large and the equipment cost increases. In addition, since the volume of the stirred cleaning chamber is large, the amount of cleaning water to be used is large, and the cost for treating the wastewater increases, resulting in an increase in running cost.

さらに、前記特許文献1に記載の篩渣洗浄脱水装置は、篩渣の搬送、脱水、搬出をスクリューコンベアの駆動力により行っているが、前記スクリューコンベアが1本の共通軸上に配されているため、たとえそのスクリュウピッチを調整したとしても、篩渣の搬送、脱水、搬出を円滑に行うのは困難であり、大きな駆動力が必要となり、動力費が嵩むという問題がある。   Furthermore, the sieve cleaning and dehydrating apparatus described in Patent Document 1 performs the transfer, dehydration and unloading of the sieve with the driving force of the screw conveyor. The screw conveyor is arranged on one common shaft. Therefore, even if the screw pitch is adjusted, it is difficult to smoothly transport, dewater and carry out the sieve residue, which requires a large driving force and increases the power cost.

本発明は、上記課題を解決するためになされたもので、コンパクトな装置構成とすることで設備費の増大を防止すると共に、篩渣の搬送、脱水、搬出を円滑且つ確実に行うことを可能とすることにより動力費の低減を図りつつ高い洗浄能力を有する篩渣洗浄脱水装置を提供することを目的とする。   The present invention has been made to solve the above-mentioned problems, and it is possible to prevent the increase in the equipment cost by adopting a compact apparatus configuration, and to smoothly and reliably carry the sieve, dehydrate and carry out the sieve. Accordingly, an object of the present invention is to provide a sieve cleaning and dehydrating apparatus having a high cleaning ability while reducing the power cost.

図1は、本発明に係る篩渣洗浄脱水装置の一実施形態を示す概略構成図である。図1に示すように、本発明に係る篩渣洗浄脱水装置20は、篩渣が投入されるホッパー1と、該ホッパー1に投入された篩渣を搬送用スクリューコンベア2により搬送する搬送部21と、前記搬送用スクリューコンベア2により搬送されてきた篩渣を、洗浄用スクリューコンベア3により搬送しながら洗浄する洗浄部22と、前記洗浄用スクリューコンベア3により搬送されてきた篩渣の脱水を行う脱水部23とを備えている。さらに、この篩渣洗浄脱水装置20は、前記搬送用スクリューコンベア2と、前記洗浄用スクリューコンベア3とが、それぞれ単独に、若しくは連動して回転可能としたものである。   FIG. 1 is a schematic configuration diagram showing an embodiment of a sieve cleaning and dehydrating apparatus according to the present invention. As shown in FIG. 1, a sieve washing and dehydrating apparatus 20 according to the present invention includes a hopper 1 into which sieves are charged, and a conveyance unit 21 that conveys the sieve particles introduced into the hopper 1 by a conveying screw conveyor 2. And a cleaning unit 22 for cleaning the sieve transported by the transport screw conveyor 2 while transporting it by the cleaning screw conveyor 3, and dehydrating the sieve transported by the cleaning screw conveyor 3 And a dehydrating unit 23. Further, the sieve cleaning and dewatering device 20 is configured such that the conveying screw conveyor 2 and the cleaning screw conveyor 3 can rotate independently or in conjunction with each other.

ホッパー1に投入された篩渣は、ホッパー1の下部に設けられた搬送部21内に設置された搬送用スクリューコンベア2により搬送され洗浄部22内に送られる。ここで、前記搬送用スクリューコンベア2は、らせん状のスクリュー2aがその外周部に設けられた回転軸2bを、正逆回転自在の搬送用スクリューコンベア駆動装置7により回転することで篩渣の搬送を行う。なお、前記搬送用スクリューコンベア回転軸2bは、公知の軸受け部及びシール部を介して搬送部21を貫通して設置されているものとし、前記搬送部21の外部に設置された搬送用スクリューコンベア駆動装置7により回転する。また、前記らせん状のスクリュー2aは搬送部21の内壁に接するように設けられている。   The sieve cake put into the hopper 1 is conveyed by the conveying screw conveyor 2 installed in the conveying unit 21 provided at the lower part of the hopper 1 and sent into the cleaning unit 22. Here, the conveying screw conveyor 2 conveys a sieve by rotating a rotating shaft 2b provided with a spiral screw 2a on the outer periphery thereof by a conveying screw conveyor driving device 7 which can be rotated forward and backward. I do. The conveying screw conveyor rotary shaft 2b is installed through the conveying unit 21 via a known bearing unit and a sealing unit, and the conveying screw conveyor installed outside the conveying unit 21. It is rotated by the driving device 7. Further, the spiral screw 2 a is provided so as to contact the inner wall of the transport unit 21.

前記洗浄部22内に供給された篩渣は、洗浄部22壁面に設けられた洗浄水噴射ノズル9から噴射される洗浄水によって洗浄される。ここで、前記洗浄水噴射ノズル9は、洗浄をより効果的に行うために、洗浄水の噴射方向がそれぞれ異なるように複数本設け、洗浄部22内に噴射することが好ましい。前記洗浄水は、洗浄水噴射ノズル9に洗浄水を供給するための洗浄水供給配管10の途中に設けられた洗浄水調整弁11により、その流量及び圧力が調整される。   The sieve residue supplied into the cleaning unit 22 is cleaned by the cleaning water sprayed from the cleaning water spray nozzle 9 provided on the wall surface of the cleaning unit 22. Here, in order to perform cleaning more effectively, it is preferable that a plurality of the cleaning water injection nozzles 9 are provided so that the injection directions of the cleaning water are different from each other and are injected into the cleaning unit 22. The flow rate and pressure of the cleaning water are adjusted by a cleaning water adjustment valve 11 provided in the middle of the cleaning water supply pipe 10 for supplying the cleaning water to the cleaning water jet nozzle 9.

前記洗浄部22内の篩渣は洗浄用スクリューコンベア3により搬送され、汚物等の有機成分が除去された後、脱水部23に送られる。前記洗浄用スクリューコンベア3は、らせん状のスクリュー3aがその外周部に設けられた洗浄用スクリューコンベア回転軸3bを、正逆回転自在の洗浄用スクリューコンベア駆動装置8により回転することで篩渣の搬送を行う。ここで、前記洗浄用スクリューコンベア回転軸3bは、例えば、図1に示すように、中空構造とした前記搬送用スクリューコンベア回転軸2bの軸内を貫通して設置されているものとし、前記搬送部21及び前記脱水部23の外部に設置された洗浄用スクリューコンベア駆動装置8により回転する。なお、前記洗浄用スクリューコンベア回転軸3bは、公知の軸受け部及びシール部を介して搬送用スクリューコンベア回転軸2bの軸内を貫通して、回転自在に設置されている。また、前記らせん状のスクリュー3aは洗浄部22の内壁に接するように設けられている。   The sieve residue in the cleaning unit 22 is conveyed by the cleaning screw conveyor 3 and is sent to the dehydrating unit 23 after organic components such as filth are removed. The cleaning screw conveyor 3 has a helical screw 3a provided on the outer periphery thereof, and the cleaning screw conveyor rotating shaft 3b is rotated by a cleaning screw conveyor driving device 8 which can be rotated in the forward and reverse directions. Transport. Here, for example, as shown in FIG. 1, the cleaning screw conveyor rotary shaft 3b is installed to penetrate through the inside of the transfer screw conveyor rotary shaft 2b having a hollow structure, and the transfer It is rotated by a cleaning screw conveyor driving device 8 installed outside the section 21 and the dehydrating section 23. The cleaning screw conveyor rotating shaft 3b is rotatably installed through the shaft of the conveying screw conveyor rotating shaft 2b via a known bearing portion and a seal portion. The helical screw 3 a is provided so as to contact the inner wall of the cleaning unit 22.

前記搬送用スクリューコンベア2のスクリュー2aのピッチ間隔と、前記洗浄用スクリューコンベア3のスクリュー3aのピッチ間隔は、例えば、前記スクリュー3aのピッチ間隔を前記スクリュー2aのピッチ間隔より狭くすることが好ましい。搬送部21より送られてくる篩渣が、前記スクリュー2aと前記スクリュー3aとの間に設けられるゾーンで剪断作用を受け、紐状あるいは繊維状の篩渣が細分化され、その結果、洗浄効果が向上するからである。   As for the pitch interval of the screw 2a of the screw conveyor 2 for conveyance and the pitch interval of the screw 3a of the screw conveyor 3 for washing | cleaning, it is preferable to make the pitch interval of the screw 3a narrower than the pitch interval of the screw 2a, for example. The sieve sent from the transport unit 21 is subjected to a shearing action in a zone provided between the screw 2a and the screw 3a, and the string-like or fibrous sieve is subdivided, resulting in a cleaning effect. This is because it improves.

前記搬送部21及び洗浄部22の下方にはスクリーン4を介してドレンパン5が設置されており、篩渣中の水分及び洗浄排水が、前記ドレンパン5に設けられた排水口6から排出され、排水処理施設等に送られる。   A drain pan 5 is installed below the transport unit 21 and the cleaning unit 22 via the screen 4. Water and cleaning wastewater in the sieve are discharged from a drain port 6 provided in the drain pan 5, and drained. Sent to a processing facility.

前記洗浄用スクリューコンベア3により脱水部23に送られた洗浄後の篩渣は、この脱水部23において脱水処理される。前記脱水部23は、前記洗浄部22の篩渣押し出し方向下流側に設けられた背圧管等により構成することができる。前記背圧管は、例えば、前記洗浄部22との接続端部と反対側の端部を上方に伸びるように屈曲させたエルボ管等を用いることができる。   The washed sieve cake sent to the dewatering unit 23 by the cleaning screw conveyor 3 is dehydrated in the dewatering unit 23. The dewatering unit 23 can be configured by a back pressure pipe or the like provided on the downstream side of the cleaning unit 22 in the sieve pushing direction. As the back pressure pipe, for example, an elbow pipe or the like that is bent so as to extend upward at the end opposite to the connection end with the cleaning section 22 can be used.

洗浄部22から押し出された篩渣が、前記脱水部23を通過する際に、背圧管との間で受ける圧縮、及び、篩渣が背圧管内を移動する際の摩擦抵抗によって、篩渣は十分に脱水される。なお、前記背圧管は、鉛直上方に屈曲させることが好ましく、また、洗浄部22との接続端部と反対側の端部を縮径することも脱水をより効果的に行うのに有効である。   When the sieve pushed out from the washing part 22 passes through the dehydrating part 23, the sieve receives the compression from the back pressure pipe and the frictional resistance when the sieve moves through the back pressure pipe. It is fully dehydrated. The back pressure tube is preferably bent vertically upward, and reducing the diameter of the end opposite to the connection end with the cleaning unit 22 is also effective for more effective dehydration. .

以下、本実施形態に係る篩渣洗浄脱水装置を用いた篩渣の洗浄脱水方法の一例を、図1を参照しながら説明する。   Hereinafter, an example of a method for washing and dehydrating a sieve using the sieve washing and dehydrating apparatus according to this embodiment will be described with reference to FIG.

ホッパー1に洗浄脱水処理される篩渣が投入されると、搬送用スクリューコンベア2と洗浄用スクリューコンベア3とが運転を開始し、篩渣が搬送部21から洗浄部22に送り込まれる。前記搬送用スクリューコンベア2のスクリュー2aのピッチ間隔が前記洗浄用スクリューコンベア3のスクリュー3aのピッチ間隔より広い場合には、搬送用スクリューコンベア2の回転数を洗浄用スクリューコンベア3の回転数より低回転とし、単位時間当たりの篩渣の輸送量を同程度に設定することが好ましい。これにより、篩渣の詰まり等搬送トラブルが起こりにくくなるからである。   When the sieve to be washed and dehydrated is introduced into the hopper 1, the conveying screw conveyor 2 and the washing screw conveyor 3 start operation, and the sieve is sent from the conveying unit 21 to the washing unit 22. When the pitch interval of the screws 2a of the conveying screw conveyor 2 is wider than the pitch interval of the screws 3a of the cleaning screw conveyor 3, the rotational speed of the conveying screw conveyor 2 is lower than the rotational speed of the cleaning screw conveyor 3. It is preferable to set the amount of transport of the sieve per unit time to the same level. This is because it is difficult for transport troubles such as clogging of sieves to occur.

洗浄部22に篩渣が全て送り込まれた段階で前記搬送用スクリューコンベア2の運転を停止し、前記洗浄用スクリューコンベア3のみ運転を継続する。このとき、前記洗浄用スクリューコンベア3の回転方向を、例えば所定時間毎に反転させることが好ましい。これにより、篩渣を洗浄部22内に所定時間留め置くことが可能となり、確実に洗浄が行えることにより篩渣の洗浄効果が向上する。また、洗浄部22内での篩渣の混合攪拌と揉み解しとが同時に行われるので洗浄効果が向上する。さらに、搬送用スクリューコンベア2を反転させることにより、搬送部21内での篩渣の詰まり防止効果が向上する。   The operation of the conveying screw conveyor 2 is stopped at the stage when all the sieves are fed into the cleaning unit 22, and only the cleaning screw conveyor 3 is operated. At this time, it is preferable to reverse the rotation direction of the screw conveyor 3 for cleaning, for example, every predetermined time. As a result, the sieve can be kept in the cleaning unit 22 for a predetermined time, and the cleaning effect of the sieve is improved by performing the cleaning reliably. In addition, since the mixing and stirring of the sieve in the cleaning unit 22 and the squeezing are simultaneously performed, the cleaning effect is improved. Furthermore, the effect of preventing clogging of the sieve in the transport unit 21 is improved by reversing the transport screw conveyor 2.

前記洗浄部22では、洗浄部22の壁面に設けられた洗浄水噴射ノズル9から噴射される洗浄水によって混合攪拌及び揉み解し中の篩渣に含まれる汚物等の有機成分が除去される。前記除去された有機成分等は、洗浄水と共にスクリーン4を通り、ドレンパン5に流れ込み、前記ドレンパン5に設けられた排水口6から排出され、排水処理施設等に送られる。   In the cleaning unit 22, organic components such as filth contained in the sieve during mixing and stirring and demulsification are removed by the cleaning water sprayed from the cleaning water spray nozzle 9 provided on the wall surface of the cleaning unit 22. The removed organic components and the like pass through the screen 4 together with the cleaning water, flow into the drain pan 5, are discharged from the drain port 6 provided in the drain pan 5, and are sent to a waste water treatment facility or the like.

前記洗浄部22で十分に洗浄された篩渣は、搬送用スクリューコンベア2と洗浄用スクリューコンベア3とを同時に、同じ回転方向に運転することで脱水部23に移送される。前記脱水部23に移送された篩渣は、前記脱水部23を構成する背圧管との間で受ける圧縮、及び、篩渣が背圧管内を移動する際の摩擦抵抗によって脱水処理される。前記脱水処理された篩渣は、搬送用スクリューコンベア2及び洗浄用スクリューコンベア3の回転による押し出し圧力により前記脱水部23の排出端部より排出される。ここで、前記搬送用スクリューコンベア2の回転数を洗浄用スクリューコンベア3の回転数より低回転とし、単位時間当たりの篩渣の輸送量を同程度に設定することが好ましい。これにより、篩渣の詰まり等搬送トラブルが起こりにくくなるからである。   The sieve that has been sufficiently washed by the washing unit 22 is transferred to the dehydrating unit 23 by simultaneously operating the conveying screw conveyor 2 and the washing screw conveyor 3 in the same rotational direction. The sieve transferred to the dewatering unit 23 is dehydrated by the compression received between it and the back pressure tube constituting the dewatering unit 23 and the frictional resistance when the sieve moves in the back pressure tube. The dehydrated sieve residue is discharged from the discharge end of the dewatering unit 23 by the extrusion pressure generated by the rotation of the conveying screw conveyor 2 and the cleaning screw conveyor 3. Here, it is preferable that the rotational speed of the conveying screw conveyor 2 is set to be lower than the rotational speed of the cleaning screw conveyor 3, and the transport amount of the sieve per unit time is set to the same level. This is because it is difficult for transport troubles such as clogging of sieves to occur.

なお、前記脱水部23の排出端部は、本篩渣洗浄脱水装置の設置状況等により適宜変形され得る。   The discharge end of the dewatering unit 23 can be appropriately modified depending on the installation status of the present sieve cleaning and dewatering device.
