【考案の詳細な説明】
この考案は、循環曝気水路において曝気機能と
曝気槽内に流速を生じせしめるポンプ機能の両機
能を有する曝気装置に関するものである。[Detailed Description of the Invention] This invention relates to an aeration device that has both an aeration function in a circulating aeration waterway and a pump function to generate a flow velocity in an aeration tank.
従来この種の曝気装置としては、第１図に示す
ように、回転軸１にこの軸を中心として放射状に
かつ周方向に等間隔をおいて多数のインペラ２を
取付け、回転軸１の周囲に空間３が生じるように
各インペラ２間に阻止板４を設けたものがある。
しかしながら、このような曝気装置の場合、曝気
槽内で生長した夾雑物がインペラ２に引つ掛かる
可能性がある。 Conventionally, as shown in Fig. 1, in this type of aeration system, a large number of impellers 2 are attached to a rotating shaft 1 at equal intervals radially and circumferentially around this shaft. There is one in which a blocking plate 4 is provided between each impeller 2 so that a space 3 is created.
However, in the case of such an aeration device, there is a possibility that impeller 2 may get caught by foreign substances grown in the aeration tank.
この考案はこのような問題点を改良すべく創案
されたもので、その目的は夾雑物の引つ掛かりが
防止されるとともに強い螺旋流を得ることのでき
る曝気装置を提供することにある。 This invention was devised to solve these problems, and its purpose is to provide an aeration device that can prevent foreign matter from getting caught and can generate a strong spiral flow.
この考案に係る曝気装置は、回転軸と阻止板と
の間の空間にガイドタービン羽根を設け、阻止板
の吸込側端部および前記ガイドタービン羽根の回
転方向端部を折り曲げたものである。 The aeration device according to this invention has a guide turbine blade provided in a space between a rotating shaft and a blocking plate, and the suction side end of the blocking plate and the rotational direction end of the guide turbine blade are bent.
以下この考案を図示する一実施例に基づいて説
明する。なお、従来と同一あるいは相当する部分
の説明は省略する。第２図、第３図に示すように
空間３内にガイドタービン羽根５が設けられ、こ
のガイドタービン羽根５はインペラ２と一体構造
とされている。 This invention will be explained below based on an illustrated embodiment. Note that explanations of parts that are the same as or correspond to the conventional ones will be omitted. As shown in FIGS. 2 and 3, a guide turbine blade 5 is provided within the space 3, and the guide turbine blade 5 is integrally constructed with the impeller 2. As shown in FIGS.
第４図、第５図に示すように阻止板４の吸込側
下端部およびガイドタービン羽根５の回転方向下
端部を折り曲げて折曲部６および７を形成する。
また、第６図に示すようにインペラ２の上端部に
も折曲部８が形成されている。 As shown in FIGS. 4 and 5, bent portions 6 and 7 are formed by bending the lower end of the blocking plate 4 on the suction side and the lower end of the guide turbine blade 5 in the rotational direction.
Further, as shown in FIG. 6, a bent portion 8 is also formed at the upper end of the impeller 2.
このような構成において回転軸１を回転させれ
ば、ガイドタービン羽根５により上部への揚水が
促進され、インペラ２の折曲部８により揚水され
た液体が遠心分散され、曝気を行なうとともに曝
気ゾーンに螺旋流を生ぜしめる。また、折曲部
６，７により夾雑物の引つ掛かりが防止される。 When the rotary shaft 1 is rotated in such a configuration, the guide turbine blades 5 promote the pumping of water to the upper part, and the bent portion 8 of the impeller 2 centrifugally disperses the pumped liquid, which performs aeration and flows into the aeration zone. This causes a spiral flow. Further, the bent portions 6 and 7 prevent foreign matter from getting caught.
この考案に係る曝気装置は以上のような構成か
らなるので、ポンプ機能が増大し強い撹拌を行な
うと共に夾雑物の引つ掛りを防止することができ
る。 Since the aeration device according to this invention has the above-described configuration, the pump function is increased, strong agitation is performed, and it is possible to prevent foreign substances from being caught.
