この発明はスラッジの中に空気を流通させスラッジに含
まれる水分を脱水するスラッジ処理装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sludge treatment device that dehydrates water contained in sludge by circulating air through the sludge.
下水などの排水を処理する処理槽の底に沈澱したスラッ
ジを投棄する場合、処理槽から取り出したばかりのスラ
ッジにはまだ相当量の水分が含まれているので、体、積
および重量が犬であり運搬などが不便である。When dumping settled sludge at the bottom of a treatment tank that treats wastewater such as sewage, the sludge that has just been taken out of the treatment tank still contains a considerable amount of water, so the volume, volume, and weight of the sludge are small. It is inconvenient to transport.
そこで、スラッジの中に空気を通し、この空気流により
スラッジの粒子に付着した水分を取除き、スラッジを脱
水し、運搬などを便利にしている。Therefore, air is passed through the sludge, and this air flow removes the moisture attached to the sludge particles, dewatering the sludge and making it convenient to transport.
第１図は従来この種の処理装置を示している。FIG. 1 shows a conventional processing apparatus of this type.
図において、１はスラッジ２が収納された処理槽、３は
真空室４が形成された支持台、５は支持台３の上に装着
された支持板で、空気および水が通過する多数の孔６が
設けられている。In the figure, 1 is a processing tank in which sludge 2 is stored, 3 is a support base on which a vacuum chamber 4 is formed, and 5 is a support plate mounted on the support base 3, which has numerous holes through which air and water pass. 6 is provided.
７は炉布、８は真空室４内の真空引を行うための真空ポ
ンプ、９は処理槽１の外周に装着されたシール部材で、
内部に空気が充填された弾性体よりなる袋で構成されて
いる。7 is a furnace cloth; 8 is a vacuum pump for evacuating the vacuum chamber 4; 9 is a sealing member attached to the outer periphery of the processing tank 1;
It consists of an elastic bag filled with air.
次にスラッジを脱水する動作を説明する。Next, the operation of dewatering sludge will be explained.
沈澱槽（図示せず）内のスラッジを処理槽１の中に投入
すると、スラッジ２が処理槽１の下部にたまる。When the sludge in the settling tank (not shown) is put into the treatment tank 1, the sludge 2 accumulates at the bottom of the treatment tank 1.
この状態で、真空ポンプ８を駆動させ真空室４内の真空
引を行うと、処理槽１内の水が炉布７の孔６を通って真
空室４へ流入し、さらに真空が引かれるとスラッジ２の
上側の空気がスラッジ２、孔６および炉布Ｔを通過して
真空室４へ流入する。In this state, when the vacuum pump 8 is driven to evacuate the vacuum chamber 4, the water in the processing tank 1 flows into the vacuum chamber 4 through the holes 6 of the furnace cloth 7, and when the vacuum is further drawn. Air above the sludge 2 passes through the sludge 2, the holes 6 and the oven cloth T and flows into the vacuum chamber 4.
この空気はスラッジ２を通過中においてスラッジ２の粒
子に付着した水分を取り除き、このようにしてスラッジ
２の脱水が行なわれる。While passing through the sludge 2, this air removes moisture adhering to the particles of the sludge 2, and in this way, the sludge 2 is dehydrated.
脱水されたスラッジ２はケーキ状となり体積が小さくな
り重量が軽くなる。The dehydrated sludge 2 becomes cake-like, has a smaller volume, and is lighter in weight.
従来の脱水装置は以上のようにして脱水を行うが、スラ
ッジ２の脱水過程において、スラッジ２は収縮してその
表面積が維持できなくなり第１図に示すようにスラッジ
２と処理槽１との間にすき間１０が生じ、さらにスラッ
ジ２の表面にひび割れ１１が生じる。Conventional dewatering equipment dewaters as described above, but during the dewatering process of sludge 2, sludge 2 shrinks and cannot maintain its surface area, and as shown in Fig. A gap 10 is created, and cracks 11 are created on the surface of the sludge 2.
これらのすき間１０およびひび割れ１１が生じると、空
気がこれらのすき間１０およびひび割れ１１を通って真
空室４に吸込まれるので、矢印Ａで示す部分を通過する
空気が少なくなり、この部分Ａの脱水効果は悪くなる。When these gaps 10 and cracks 11 occur, air is sucked into the vacuum chamber 4 through these gaps 10 and cracks 11, so less air passes through the area indicated by arrow A, and dehydration in this area A is reduced. The effect gets worse.
しかも、ひび割れ１１はフラッジ２の表面に数個所しか
発生せず、発生する場所も均一ではないので空気が流れ
る個所が偏りスラッジ２の均等な脱水が困難であった。Furthermore, the cracks 11 were only formed in a few places on the surface of the fludge 2, and the cracks 11 were not evenly formed, so that the air flowed unevenly, making it difficult to dewater the sludge 2 evenly.
この発明の以上の点に鑑みてなされたものでスラッジの
中に空気を均等に通過させる挿入部材を設けることによ
り上記欠点のない処理装置を提供することを目的とする
ものである。The present invention has been made in view of the above points, and it is an object of the present invention to provide a treatment device that does not have the above-mentioned drawbacks by providing an insertion member that allows air to pass through the sludge evenly.
以下、第２図に示すこの発明の一実施例について説明す
る。An embodiment of the present invention shown in FIG. 2 will be described below.
図において、１〜９は第１図に示す従来の処理装置と同
様であるので説明を省略する。In the figure, numerals 1 to 9 are the same as those of the conventional processing apparatus shown in FIG. 1, so their explanation will be omitted.
１２は第３図に示すように格子状をした仕切板からなる
挿入部材で、一部が脱水中のスラッジ２の中に挿入され
るような状態で、処理槽１の内側に装着されている。As shown in Fig. 3, reference numeral 12 denotes an insertion member consisting of a grid-shaped partition plate, which is attached to the inside of the treatment tank 1 so that a part thereof is inserted into the sludge 2 during dewatering. .
脱水中において、スラッジ２が収縮すると、スラッジ２
と仕切板１２との間にすき間１３でき、仕切板１２の下
端にひび割れ１４が生じる。When the sludge 2 shrinks during dewatering, the sludge 2
A gap 13 is created between the partition plate 12 and the partition plate 12, and a crack 14 is generated at the lower end of the partition plate 12.
そしてこのひび割れ１４を通って空気が流れる。Air flows through this crack 14.
この場合、仕切板１２がスラッジ２の表面に均等に配置
されているので、ひび割れ１４が均等に生じる。In this case, since the partition plates 12 are evenly arranged on the surface of the sludge 2, cracks 14 occur evenly.
′ことになり、スラッジ２内を空気が均等に通過する。'As a result, air passes through the sludge 2 evenly.
仕切板１２の格子の目を小さくすれば、ひび割れ１４の
数が多くなり空気はより均等にスラッジ２内を通過する
。If the grid of the partition plate 12 is made smaller, the number of cracks 14 will increase and air will pass through the sludge 2 more evenly.
以上のようにこの発明の処理装置は脱水中のスラッジの
中に挿入部材を配置し、この挿入部材によってひび割れ
を生じさせるので、ひび割れが生じる位置の分布を改善
し、空気を均等にスラッジの中を通過させることができ
る。As described above, the treatment device of the present invention places an insertion member in the sludge during dewatering, and this insertion member causes cracks, thereby improving the distribution of the positions where cracks occur and distributing air evenly into the sludge. can be passed.
このため、スラッジの脱水効果が非常に良好であると云
う効果を奏する。Therefore, the sludge dewatering effect is very good.
なお、上記説明は真空脱水を行う場合について説明した
が、この発明はこれに限らず圧縮空気を用いて通気脱水
する゛処理装置に用いても同様の効果を奏する。Although the above description has been made regarding the case where vacuum dehydration is performed, the present invention is not limited to this, and the same effect can be achieved even when the present invention is applied to a processing apparatus that performs aeration dehydration using compressed air.
