Description

本考案は、浄水場や下水処理場、あるいは河川、ため池などで発生する汚泥を天日乾燥させるための汚泥脱水乾燥装置に関する。   The present invention relates to a sludge dewatering and drying apparatus for drying sun sludge generated at a water purification plant, a sewage treatment plant, a river, a pond, or the like.

この種の汚泥脱水乾燥装置として、先に同一出願人により、図７に示すように、複数の乾燥棚２１〜２４を上下に所定間隔を置いて数段階に重合配置し、乾燥棚２１〜２４の両端部に汚泥を収容する濾過容器２０を各段の乾燥棚の高さまで昇降させるリフター装置２５Ｌ，２５Ｒを配置させて、汚泥入り濾過容器２０を下段の乾燥棚から上段の乾燥棚へリフター装置２５Ｌ，２５Ｒにより順次移動させながら高含水汚泥も乾燥効率良く天日乾燥できるようにしたものを提案した（例えば、特許文献１参照。）。   As this kind of sludge dewatering and drying apparatus, as shown in FIG. 7, a plurality of drying shelves 21 to 24 are superposed and arranged in several stages at a predetermined interval in the vertical direction, and drying shelves 21 to 24 are used. Lifter devices 25L and 25R for raising and lowering the filtration container 20 containing sludge to the height of the drying shelves at each stage are arranged at both ends of the filter so that the sludge-containing filtration container 20 is moved from the lower drying shelf to the upper drying shelf. A system has been proposed in which high water content sludge can be efficiently dried by the sun while being moved sequentially by 25L and 25R (see, for example, Patent Document 1).

特許第３６１６７３８号公報Japanese Patent No. 3616738

しかるに、上記のような多段式の汚泥脱水乾燥装置では、複数の乾燥棚２１〜２４を上下に数段階に重合配置するため、大量汚泥を天日乾燥する場合にも敷地面積の有効利用を図れるが、その半面、太陽の光が上段側の棚により遮られて下段側の棚が日陰になる場合があり、それだけ天日乾燥効率が低下することがあり、また濾過容器２０を各段の棚２１〜２４の高さまで昇降させるためのリフター装置２５Ｌ，２５Ｒを必要とするため、設備コストが高くなるという問題があった。   However, in the multi-stage sludge dewatering and drying apparatus as described above, the plurality of drying shelves 21 to 24 are arranged in several stages up and down, so that the site area can be effectively used even when a large amount of sludge is sun-dried. However, on the other hand, the sun light may be blocked by the upper shelves and the lower shelves may become shaded, so that the sun drying efficiency may be lowered. Since the lifters 25L and 25R for raising and lowering to the height of 21 to 24 are required, there is a problem that the equipment cost is increased.

本考案の目的は、大量に発生する高含水汚泥も脱水乾燥効率良い天日乾燥を確保し得ながら、上記のような多段式の汚泥脱水乾燥装置に比べ多少の敷地面積を必要とするもののリフター装置を不要にして設備コストの低減を図れる汚泥脱水乾燥装置を提供することにある。   The purpose of the present invention is to lift a high-water-containing sludge that generates a large amount of sludge, which requires a certain site area compared to the multi-stage sludge dehydration and drying device as described above, while ensuring efficient sun drying with dehydration and drying efficiency. An object of the present invention is to provide a sludge dewatering and drying apparatus that can reduce equipment costs by eliminating the need for an apparatus.

本考案の汚泥脱水乾燥装置は、その考案の内容を理解しやすくするために図１、図６に示した符号を参照して説明すると、同一地面上に横方向に長い１本もしくは２本以上の主乾燥棚（１）と、１本もしくは２本以上の副乾燥棚（２）とが横複数列に平行に並べて配置されており、主乾燥棚（１）及び副乾燥棚（２）上にそれぞれ、砂の通過を阻止し且つ水及び空気の通過を許容する濾布（４）が上面開放状の多孔容器本体（５）の内部に敷設され濾布（４）上に汚泥を収容する複数個の濾過容器（３）が主、副乾燥棚（１）（２）の長手方向に並べて載置されており、主乾燥棚（１）及び副乾燥棚（２）の長手方向の同一一側端に搬入・搬出ライン（１０）が、同一他側端に移動ライン（１１）がそれぞれ主乾燥棚（１）及び副乾燥棚（２）と直交する縦方向に配置されており、搬入・搬出ライン（１０）に、汚泥入り濾過容器（３）を主乾燥棚（１）の一側端側から該主乾燥棚上に積み込む動作と副乾燥棚（２）上の乾燥処理済み汚泥入り濾過容器（３）を該副乾燥棚の一側端側から取出して搬出する動作を行なう給排装置（１２）を備えており、移動ライン（１１）に、主乾燥棚（１）上の濾過容器（３）を該主乾燥棚の他側端側から副乾燥棚（２）の他側端側へ移載する移載装置（１６）を備えていることに特徴を有するものである。   The sludge dewatering and drying apparatus of the present invention will be described with reference to the reference numerals shown in FIGS. 1 and 6 for easy understanding of the contents of the invention. Main drying shelves (1) and one or more sub drying shelves (2) are arranged in parallel in a plurality of horizontal rows, on the main drying shelves (1) and sub drying shelves (2). In addition, a filter cloth (4) that prevents the passage of sand and allows the passage of water and air is laid inside the open top porous container body (5) and accommodates sludge on the filter cloth (4). A plurality of filtration containers (3) are placed side by side in the longitudinal direction of the main and secondary drying shelves (1) and (2), and the same lengthwise direction of the main drying shelf (1) and the secondary drying shelf (2). A carry-in / carry-out line (10) is provided at one end, and a movement line (11) is provided at the other end, respectively. And the operation of loading the sludge-containing filtration container (3) on the main drying shelf (1) from one end of the main drying shelf (1) onto the main drying shelf. It is provided with a supply / discharge device (12) for performing an operation of taking out and carrying out the dried sludge-containing filtration container (3) on the drying shelf (2) from one side end side of the sub-drying shelf. ) Includes a transfer device (16) for transferring the filtration container (3) on the main drying shelf (1) from the other side end of the main drying shelf to the other side end of the sub drying shelf (2). It has the characteristic in being.

上記構成の汚泥脱水乾燥装置によれば、水中から汲み上げられた汚泥は濾過容器に収容され、この濾過容器を主乾燥棚及び副乾燥棚の上に載置して数週間放置することで脱水、天日乾燥される。その際、当初、汚泥中の水は濾過容器の濾布を通して下方に滴下する。その後は濾過容器の開放上面からだけでなく、濾過容器の周側面及び底面からも汚泥中の水分が蒸発することになる。したがって、水の滴下終了後は汚泥における外気に接触する面積、即ち水分の蒸発面積が大幅に広くなり、汚泥の乾燥効率が高められる。つまり、汚泥入りの濾過容器が主乾燥棚、副乾燥棚の上に置かれることにより、汚泥の水切り、乾燥がきわめて良好になる。   According to the sludge dewatering and drying apparatus having the above-described configuration, the sludge pumped from the water is stored in the filtration container, and the filtration container is placed on the main drying shelf and the auxiliary drying shelf and left to stand for several weeks for dehydration. Sun-dried. At that time, initially, the water in the sludge is dripped downward through the filter cloth of the filtration container. Thereafter, the moisture in the sludge evaporates not only from the open upper surface of the filtration container but also from the peripheral side surface and the bottom surface of the filtration container. Therefore, after the completion of the dripping of water, the area in contact with the outside air in the sludge, that is, the evaporation area of the water is greatly increased, and the drying efficiency of the sludge is enhanced. That is, when the sludge-containing filtration container is placed on the main drying shelf and the sub-drying shelf, the sludge is drained and dried very well.

とくに、主乾燥棚及び副乾燥棚は同一地面上に並べて配置されるため、前述した従来の多段式の汚泥脱水乾燥装置に比べ、全ての乾燥棚に対し日当たりが良好となり、天日乾燥効率が高められ、しかも高価なリフター装置は不要となるため設備コストを低減できる利点がある。加えて、汚泥入り濾過容器は搬入・搬出ライン、主乾燥棚、移動ライン、副乾燥棚の順に流して搬入・搬出ラインに戻す、という一定方向に流す制御システムで済む利点もある。   In particular, since the main drying shelf and the secondary drying shelf are arranged side by side on the same ground, compared to the conventional multi-stage sludge dehydration drying device described above, the sundrying efficiency is better for all drying shelves and the sun drying efficiency is improved. This is advantageous in that the equipment cost can be reduced since an expensive lifter device is not required. In addition, the sludge-containing filtration container has an advantage that a control system that flows in a certain direction by flowing in the order of the carry-in / out line, the main drying shelf, the moving line, and the sub-drying shelf and returning it to the carry-in / out line.

As in the case of the supply / discharge device 12, the transfer device 16 is provided with a chain conveyor that can be mounted on a self-propelled carriage and can be driven laterally.

次に、上記構成の汚泥脱水乾燥装置の作動について説明する。
まず、高含水の汚泥を濾過容器３に投入し、この汚泥入り濾過容器３を搬入・搬出ライン１０における自走式台車１４上の給排装置１２のチェーンコンベア１５に載せ、自走式台車１４を主乾燥棚１の一側端側（入口側）１ａに停止させて給排装置１２のチェーンコンベア１５の駆動で汚泥入り濾過容器３を主乾燥棚１上に積み込む。その際、主乾燥棚１上には、複数個の汚泥入り濾過容器３が順次玉突き状に積み込まれて主乾燥棚長手方向に並ぶ状態に満載される。他の主乾燥棚１にも同様に複数個の汚泥入り濾過容器３が順次玉突き状に積み込んで満載する。このように汚泥入り濾過容器３は主乾燥棚１上に満載させた状態で数週間（例えば、３週間）ほど天日乾燥される。当初、各濾過容器３内の汚泥中の水は濾布４を通して滴下し、その後、濾過容器３の開放上面、濾過容器３の周側面及び底面から汚泥中の水分が蒸発し、汚泥を十分に乾燥することができる。 Next, the operation of the sludge dewatering and drying apparatus having the above configuration will be described.
First, the sludge containing high water content is put into the filtration container 3, and this filtration container 3 with sludge is placed on the chain conveyor 15 of the supply / discharge device 12 on the self-propelled carriage 14 in the loading / unloading line 10. Is stopped at one end (inlet side) 1 a of the main drying shelf 1, and the sludge-containing filtration container 3 is loaded onto the main drying shelf 1 by driving the chain conveyor 15 of the supply / discharge device 12. At that time, a plurality of sludge-containing filtration containers 3 are sequentially stacked in a ball shape on the main drying shelf 1 and are packed in a state in which they are arranged in the longitudinal direction of the main drying shelf. Similarly, the other main drying shelves 1 are loaded with a plurality of sludge-containing filtration containers 3 sequentially in a ball shape. Thus, the sludge-containing filtration container 3 is sun-dried for several weeks (for example, three weeks) in a state where it is packed on the main drying shelf 1. Initially, the water in the sludge in each filtration container 3 is dripped through the filter cloth 4, and then the water in the sludge evaporates from the open upper surface of the filtration container 3, the peripheral side surface and the bottom surface of the filtration container 3, and the sludge is sufficiently removed. Can be dried.

主乾燥棚１上で乾燥された汚泥入りの濾過容器３は、駄目押し乾燥のために、移動ライン１１の移載装置１６により主乾燥棚１の他側端側（出口側）１ｂから副乾燥棚２の他側端側（入り口側）２ｂへ移載する。この移載に際しては、搬入・搬出ライン１０の給排装置１２による積み込みの場合と同様に、移載装置１６のチェーンコンベアの駆動で順次移載されて副乾燥棚２上に満載される。この副乾燥棚２上では１週間ほど駄目押し乾燥される。
駄目押し乾燥後には、図４に示すように、搬入・搬出ライン１０の給排装置１２により副乾燥棚２上の乾燥処理済み汚泥入り濾過容器３を該副乾燥棚２の一側端側（出口側）２ａからチェーンコンベア１５上に取出し、図５のように自走式台車１４上で該チェーンコンベア１５を乾燥処理済み汚泥入り濾過容器３ごと操作シリンダー１７で軸Ｏ回りに反転させて乾燥処理済み汚泥入り濾過容器３から乾燥処理済み汚泥をベルトコンベア１８に移し、該ベルトコンベア１８で処理済汚泥集積場１９（図１参照）へ搬出する。
搬出後、空になった濾過容器３には再び高含水の汚泥が投入され、給排装置１２により前述した要領で主乾燥棚１上に積み込まれて行く。因みに、処理済汚泥集積場１９へ集積された乾燥汚泥は、例えばレンガの原料などに使用される。 The sludge-containing filtration container 3 dried on the main drying shelf 1 is sub-drying shelf from the other end side (exit side) 1b of the main drying shelf 1 by the transfer device 16 of the moving line 11 for useless drying. 2 is transferred to the other end side (entrance side) 2b. In this transfer, as in the case of loading by the loading / unloading device 12 of the loading / unloading line 10, the transfer is performed sequentially by driving the chain conveyor of the transfer device 16 and is fully loaded on the sub-drying shelf 2. The sub-drying shelf 2 is pressed and dried for about a week.
After useless drying, as shown in FIG. 4, the filtration container 3 containing the dried sludge on the subdrying shelf 2 is placed on one side end side (exit) of the subdrying shelf 2 by the supply / discharge device 12 of the carry-in / out line 10. Side) 2a is taken out onto the chain conveyor 15, and the chain conveyor 15 is dried around the axis O by the operation cylinder 17 together with the drying sludge-containing filtration container 3 on the self-propelled carriage 14 as shown in FIG. The dried sludge is transferred to the belt conveyor 18 from the filtration container 3 containing the finished sludge, and is transported to the treated sludge accumulation site 19 (see FIG. 1) by the belt conveyor 18.
After unloading, the emptied filtration container 3 is again filled with high water content sludge and loaded onto the main drying shelf 1 by the supply / discharge device 12 as described above. Incidentally, the dried sludge accumulated in the treated sludge accumulation site 19 is used, for example, as a raw material for bricks.

このように大量の高含水汚泥も小分けして多数の濾過容器３に収容し、この多数の汚泥入り濾過容器３を搬入・搬出ライン１０、主乾燥棚１、移動ライン１１、副乾燥棚２の順に流し、主乾燥棚１上で所定日数だけ脱水、天日乾燥し、更に副乾燥棚２上では駄目押し乾燥した後、再び搬入・搬出ライン１０に戻すサイクルを経ることによって効率良く乾燥処理することができる。   In this way, a large amount of high water content sludge is subdivided and accommodated in a large number of filtration containers 3. Efficiently dry by passing through the cycle, dehydrating for a predetermined number of days on the main drying shelf 1, drying in the sun, and then pressing and drying on the secondary drying shelf 2 and then returning to the loading / unloading line 10 again. Can do.

尚、上記実施例では主乾燥棚１が２本配置されるが、１本であっても、３本以上配置するもよい。また、上記実施例では副乾燥棚２が１本設置されるが、２本以上設置するもよい。   In addition, although the two main drying shelves 1 are arrange | positioned in the said Example, you may arrange | position three or more even if it is one. In the above embodiment, one sub-drying shelf 2 is installed, but two or more sub-drying shelves may be installed.
