Description

本発明は、散気装置を固定するための固定具に関する。   The present invention relates to a fixture for fixing a diffuser.

従来の散気装置とその固定具としては、例えば、特許文献１に示すものが挙げられる。この特許文献に示されているように、浄化槽内の好気処理槽に配設される従来の散気装置は、好気処理槽の仕切壁に沿って垂設される空気供給管と、当該空気供給管の下端から水平方向に延びる一つの散気管とを備えており、側面視にてＬ字状の形状を有するものが一般的に知られている。   As a conventional diffuser and its fixture, for example, the one shown in Patent Document 1 can be cited. As shown in this patent document, a conventional air diffuser disposed in an aerobic treatment tank in a septic tank includes an air supply pipe suspended along a partition wall of the aerobic treatment tank, It is generally known that it has one diffuser pipe extending in the horizontal direction from the lower end of the air supply pipe and has an L-shape when viewed from the side.

上記散気装置を浄化槽に取り付ける従来の方法は、好気処理槽の仕切壁に沿って散気装置を下降させ、好気処理槽の仕切壁に設けられている固定具に嵌め込んで固定する。即ちこの方法では、散気装置を所定位置に固定するための左右方向の位置決めが好気処理槽の仕切壁によってなされ、前後方向の位置決めが固定具によってなされる。   In the conventional method of attaching the aeration device to the septic tank, the aeration device is lowered along the partition wall of the aerobic treatment tank, and is fitted and fixed to a fixture provided on the partition wall of the aerobic treatment tank. . That is, in this method, positioning in the left-right direction for fixing the diffuser at a predetermined position is performed by the partition wall of the aerobic treatment tank, and positioning in the front-rear direction is performed by the fixture.

ところで、好気処理槽内の被処理水中で発生させる散気装置からの散気による上昇流は、好気処理槽の平面中央部で発生させることが散気効果を高める上で好ましい。しかしながら従来の散気装置は、空気供給管が好気処理槽の仕切壁に沿って配設されるため、好気処理槽の平面中央部で上昇流を発生させるには、空気供給管の下端に設けられている散気管を、好気処理槽の少なくとも底面中央部にまで達するように延出させる必要がある。   By the way, it is preferable in order to raise the aeration effect that the upward flow by the aeration from the aeration apparatus generated in the to-be-treated water in the aerobic treatment tank is generated at the center of the plane of the aerobic treatment tank. However, in the conventional diffuser, since the air supply pipe is disposed along the partition wall of the aerobic treatment tank, the lower end of the air supply pipe is used to generate an upward flow in the center of the plane of the aerobic treatment tank. It is necessary to extend the air diffusing tube provided at the bottom so as to reach at least the center of the bottom of the aerobic treatment tank.

従って従来の散気装置においては、その散気管の全長が長いものとなるため先端が浮き易くなる。その結果、散気管の水平姿勢が維持され難く、好気処理槽の平面中央部において上昇流が発生し難くなる場合が生じていた。   Therefore, in the conventional air diffuser, since the entire length of the air diffuser is long, the tip tends to float. As a result, it was difficult to maintain the horizontal posture of the diffuser tube, and it was difficult to generate an upward flow at the center of the plane of the aerobic treatment tank.

本発明の目的は、好気処理槽の平面中央部において、散気装置の散気による上昇流をより確実に発生させて散気効果を向上させることにある。   An object of the present invention is to improve the aeration effect by more reliably generating an upward flow due to the aeration of the aeration apparatus in the center of the plane of the aerobic treatment tank.

本発明に係る固定具の第１特徴構成は、散気装置を固定するための固定具であって、前記散気装置が、同方向で芯ずれする複数の散気管と、該複数の散気管同士を連結する接続部とを備え、前後方向において前記散気装置の散気管を所定位置に案内する第１ガイド部と、左右方向において前記散気装置の接続部を前記固定具の受け部に案内する第２ガイド部と、を備え、前記第１ガイド部と前記第２ガイド部とが一体に形成されている点にある。   1st characteristic structure of the fixing tool which concerns on this invention is a fixing tool for fixing an air diffuser, Comprising: The said air diffuser is a plurality of air diffuser tubes which are misaligned in the same direction, and these air diffuser tubes A first guide portion that guides the diffuser pipe of the diffuser device to a predetermined position in the front-rear direction, and a connection portion of the diffuser device in the left-right direction as a receiving portion of the fixture. A second guide portion for guiding, wherein the first guide portion and the second guide portion are integrally formed.

〔作用及び効果〕
本構成によれば、被処理水を湛えた好気処理槽において作業者が固定具を確認し難い状況にあったとしても、固定具の第１ガイド部及び第２ガイド部のそれぞれが前後方向及び左右方向に散気装置を案内するため、散気装置を確実に固定することができる。 [Action and effect]
According to this configuration, each of the first guide portion and the second guide portion of the fixture is in the front-rear direction even if it is difficult for the operator to check the fixture in the aerobic treatment tank containing the treated water. In addition, since the air diffuser is guided in the left-right direction, the air diffuser can be securely fixed.

従って、本発明の固定具を好気処理槽の底面中央部に設置することにより、好気処理槽の底面中央部に散気装置を容易に設置することができるようになるため、好気処理槽の平面中央部において、より確実に上昇流を発生させることができる。さらに本構成によれば、接続部が固定具の受け部に収容されるため、散気管からの空気放出が固定具によって妨げられることがなく、より高い散気効果が発揮される。   Therefore, by installing the fixture of the present invention at the center of the bottom of the aerobic treatment tank, it becomes possible to easily install the diffuser at the center of the bottom of the aerobic treatment tank. An upward flow can be generated more reliably at the center of the plane of the tank. Furthermore, according to this structure, since a connection part is accommodated in the receiving part of a fixing tool, the air discharge | release from a diffuser tube is not prevented by a fixing tool, but a higher aeration effect is exhibited.

第２特徴構成は、前記散気装置の高さ位置を規定する係止部を備え、該係止部と前記第１ガイド部と前記第２ガイド部とが一体に形成されている点にある。   The second characteristic configuration includes a locking portion that defines a height position of the air diffuser, and the locking portion, the first guide portion, and the second guide portion are integrally formed. .

〔作用及び効果〕
本構成によれば、散気装置の上下方向の位置を係止部によって規定することができるため、散気装置を固定具の受け部に嵌め込む際、散気装置をどこまで下げれば良いのか判断できずに上から力を加え過ぎて固定具を破壊してしまうということを防ぐことができる。 [Action and effect]
According to this configuration, since the vertical position of the air diffuser can be defined by the locking portion, it is determined how much the air diffuser should be lowered when fitting the air diffuser into the receiving part of the fixture. It is possible to prevent the fixture from being destroyed by applying too much force from above.

第３特徴構成は、固定した前記散気装置の下方に隙間が形成される点にある。   The third characteristic configuration is that a gap is formed below the fixed air diffuser.

〔作用及び効果〕
本構成によれば、固定した散気装置の下方に隙間が形成されるため、例えば、好気処理槽中に複数の流動担体が存在する状況下で散気装置を固定する場合において、仮に流動担体が固定具の受け部に巻き込まれてしまったとしても、当該流動担体を隙間に逃がすことができるため、散気装置の固定になんら支障が生じることはない。 [Action and effect]
According to this configuration, since a gap is formed below the fixed air diffuser, for example, when the air diffuser is fixed in a situation where a plurality of fluid carriers are present in the aerobic treatment tank, the flow is temporarily Even if the carrier is caught in the receiving part of the fixture, the fluid carrier can escape into the gap, so that there is no problem in fixing the diffuser.

第４特徴構成は、前後方向に延びる前記接続部の両端のそれぞれに、左右方向に延びる前記散気管が設けられており、前記散気管及び前記接続部が平面視でＨ字状に構成されている点にある。   In the fourth characteristic configuration, the diffuser pipe extending in the left-right direction is provided at each of both ends of the connection part extending in the front-rear direction, and the diffuser pipe and the connection part are configured in an H shape in plan view. There is in point.

〔作用及び効果〕
本構成によれば、散気管及び接続部が平面視でＨ字状に構成されているため、散気管と接続部で構成される散気部分が所謂二軸型となり、従来の一軸型（一本）の散気管と比べて散気量を増やすことが可能となり、より高い散気効果が発揮される。 [Action and effect]
According to this configuration, since the diffuser tube and the connection portion are configured in an H shape in a plan view, the diffuser portion formed by the diffuser tube and the connection portion becomes a so-called biaxial type, and the conventional uniaxial type (one It becomes possible to increase the amount of air diffused compared with the air diffuser tube of this), and a higher air diffuser effect is exhibited.

また本実施形態においては、支持部材２０の傾斜部２３が、前後方向において上記散気装置Ｅの散気管６を所定位置に案内する第１ガイド部を構成し、支持部材２０の第１傾斜面２１が、左右方向において上記散気装置Ｅの接続部１０を受け部３２に案内する第２ガイド部を構成する。また、支持部材２０の段部３０が、上記散気装置Ｅの高さ位置を規定する係止部を構成する。本実施形態では、固定具Ｆにおいて、第１ガイド部と第２ガイド部と係止部とが一体に形成されている。   In the present embodiment, the inclined portion 23 of the support member 20 constitutes a first guide portion that guides the diffuser pipe 6 of the diffuser E to the predetermined position in the front-rear direction, and the first inclined surface of the support member 20 21 constitutes a second guide part for guiding the connection part 10 of the air diffuser E to the receiving part 32 in the left-right direction. Further, the step portion 30 of the support member 20 constitutes a locking portion that defines the height position of the air diffuser E. In the present embodiment, in the fixture F, the first guide portion, the second guide portion, and the locking portion are integrally formed.

支持部材２０の構成素材としては、例えば繊維強化プラスチック（ＦＲＰ）が挙げられる。また支持部材２０は、例えば公知のハンドレイアップ成形法によって製造することができる。   Examples of the constituent material of the support member 20 include fiber reinforced plastic (FRP). The support member 20 can be manufactured by, for example, a known hand layup molding method.

本実施形態において、支持部材２０の第１傾斜面２１、第１折り曲げ部２４、第２傾斜面２５、第２折り曲げ部２６、第３傾斜面２７、接合部２８、底板部２９、段部３０、並びに第１傾斜面２１の上端部分における頂部２２及び傾斜部２３は一体成形されている。   In the present embodiment, the first inclined surface 21, the first bent portion 24, the second inclined surface 25, the second bent portion 26, the third inclined surface 27, the joint portion 28, the bottom plate portion 29, and the step portion 30 of the support member 20. The top portion 22 and the inclined portion 23 at the upper end portion of the first inclined surface 21 are integrally formed.

固定具Ｆのその他の実施形態としては、例えば図６に示すような箱状の構成としても良い。尚、上述の実施形態における構成と同様の作用・効果を有する構成については同じ符号を付して説明を省略する。   As other embodiment of the fixing tool F, it is good also as a box-shaped structure as shown, for example in FIG. In addition, about the structure which has the effect | action and effect similar to the structure in the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

上述の実施形態では固定具Ｆが２つの支持部材２０を接合させて構成されるものであるが、図６の実施形態における固定具Ｆは一部材で構成されている。また、本実施形態において、円弧状の湾曲面を備える受け部３２は、係止部としての機能も兼ねる。従って、本実施形態の固定具Ｆにおいては、第１ガイド部の傾斜部２３、第２ガイド部の第１傾斜面２１、受け部３２、及び係止部が一体成形されており、部品点数が少なくて済み、製造コストを削減することができる。   In the above-described embodiment, the fixture F is configured by joining the two support members 20, but the fixture F in the embodiment of FIG. 6 is configured by one member. Moreover, in this embodiment, the receiving part 32 provided with an arc-shaped curved surface also serves as a locking part. Therefore, in the fixture F of the present embodiment, the inclined portion 23 of the first guide portion, the first inclined surface 21 of the second guide portion, the receiving portion 32, and the locking portion are integrally formed, and the number of parts is increased. Less is required and manufacturing costs can be reduced.

（固定方法）
先ず、好気処理槽Ｂの底面の所定位置、例えば平面視において略中央の位置に固定具Ｆを固定する。固定の際は、例えば底板部２９の裏面に接着剤を塗布して好気処理槽Ｂの底面に張り付けようにすれば良い。尚、好気処理槽Ｂの底面に補強用のリブが立設されている場合には、固定部の切欠き部３１に当該リブを嵌め込むようにして接着すると良い。これにより、平面視における固定部の向きが定められた状態で固定具Ｆが固定される。 (Fixing method)
First, the fixture F is fixed at a predetermined position on the bottom surface of the aerobic treatment tank B, for example, at a substantially central position in plan view. When fixing, for example, an adhesive may be applied to the back surface of the bottom plate portion 29 and attached to the bottom surface of the aerobic treatment tank B. In addition, when the rib for reinforcement is standingly arranged by the bottom face of the aerobic processing tank B, it is good to adhere | attach so that the said rib may be inserted in the notch part 31 of a fixing | fixed part. Thereby, the fixing tool F is fixed in a state where the direction of the fixing portion in plan view is determined.

次いで、固定具Ｆに散気装置Ｅを取り付ける。固定具Ｆの上方から散気装置Ｅを近づけると、散気装置Ｅの散気管６が固定具Ｆの傾斜部２３に摺接しながら前後方向の所定位置に移動する。本実施形態では、一方の軸をなす散気管６が、固定具Ｆの前後方向の一端側に案内されると共に、他方の軸をなす散気管６が固定具Ｆの前後方向の他端側に案内される。   Next, the diffuser E is attached to the fixture F. When the air diffuser E is approached from above the fixture F, the air diffuser 6 of the air diffuser E moves to a predetermined position in the front-rear direction while sliding on the inclined portion 23 of the fixture F. In the present embodiment, the air diffusion tube 6 forming one axis is guided to one end side in the front-rear direction of the fixture F, and the air diffusion tube 6 forming the other axis is guided to the other end side in the front-rear direction of the fixture F. Guided.

散気管６が所定位置に案内されると同時に、散気装置Ｅの本体部分１１が固定具Ｆの第１傾斜面２１に摺接しながら左右方向に移動し、受け部３２の上方、即ち第１折り曲げ部２４付近に案内される。   At the same time that the air diffuser 6 is guided to a predetermined position, the main body portion 11 of the air diffuser E moves in the left-right direction while sliding on the first inclined surface 21 of the fixture F, and above the receiving portion 32, that is, the first. It is guided near the bent portion 24.

２つの第１折り曲げ部２４間の左右方向の距離は、散気装置Ｅの本体部分１１の直径よりも少し小さく設定されている。従って、散気装置Ｅの本体部分１１が第１折り曲げ部２４付近に到達した際、上から力を加えて本体部分１１を押し込む必要がある。これにより、２つの第１折り曲げ部２４が本体部分１１により左右方向に押し広げられつつ、本体部分１１が下方に移動して受け部３２に収容される。本体部分１１が受け部３２に収容されると、２つの第１折り曲げ部２４はその弾性復元力により元の位置に戻る。   The distance in the left-right direction between the two first bent portions 24 is set slightly smaller than the diameter of the main body portion 11 of the air diffuser E. Therefore, when the main body portion 11 of the air diffuser E reaches the vicinity of the first bent portion 24, it is necessary to push the main body portion 11 by applying a force from above. Accordingly, the main body portion 11 moves downward and is accommodated in the receiving portion 32 while the two first bent portions 24 are expanded in the left-right direction by the main body portion 11. When the main body portion 11 is accommodated in the receiving portion 32, the two first bent portions 24 return to their original positions due to their elastic restoring force.

そして、散気装置Ｅの接続部１０又は散気管６の端部が、固定具Ｆの段部３０に当接して係止され、これにより散気装置Ｅの高さ位置が規定される。このとき、図５に示すように、散気装置Ｅの本体部分１１の下方に、縦断面が逆三角形状の隙間Ｓが形成される。   And the connection part 10 of the air diffusing device E or the edge part of the air diffusing pipe 6 is brought into contact with and locked to the stepped portion 30 of the fixture F, whereby the height position of the air diffusing device E is defined. At this time, as shown in FIG. 5, a gap S having an inverted triangular longitudinal section is formed below the main body portion 11 of the air diffuser E.

尚、本実施形態においては、固定具Ｆに対して散気装置Ｅが着脱自在に固定される。散気装置Ｅを固定具Ｆから取り外すときは、散気装置Ｅを上方に引き上げれば良い。これにより、２つの第１折り曲げ部２４が本体部分１１により左右方向に押し広げられつつ、本体部分１１が上方に移動して受け部３２から抜け出ることになる。本体部分１１が受け部３２から抜け出ると、２つの第１折り曲げ部２４はその弾性復元力により元の位置に戻る。   In this embodiment, the air diffuser E is detachably fixed to the fixture F. When removing the diffuser E from the fixture F, the diffuser E may be pulled upward. Thus, the main body portion 11 moves upward and comes out of the receiving portion 32 while the two first bent portions 24 are pushed and expanded in the left-right direction by the main body portion 11. When the main body portion 11 comes out of the receiving portion 32, the two first bent portions 24 return to their original positions due to their elastic restoring force.
