【発明の技術分野】
本発明は、嫌気性の水処理槽内における竪型水中攪拌装置に関するものである。
【０００２】
【従来の技術】
水中攪拌装置において、処理槽の水面の表層に発生する吸込み渦を抑制するための整流板をモータフレームの外周に定着させたものは、従来から存在する（例えば、特許文献１参照）。また、攪拌装置およびドラフトチューブを槽内へ垂設するための支持柱に整流板を固定させたものも、従来から存在する（例えば、特許文献２参照）。

【０００４】
【発明が解決しょうとする課題】
特許文献１および２に記載の装置では、整流板が一定位置に固定されていて上下に位置調整できない構造であるため、予め整流板を必要以上に大きくしなければならず、また、水面の表層に発生するスカムについては槽内水位に適応した有効な吸引除去が得られない。従って、別途装備された散水除去設備等によるシャワリングで除去しなければならないのが現状である。そして整流板に夾雑物が絡み付いた場合その夾雑物を除去するには、特許文献１の構造では攪拌機本体ごと槽内から引揚げなければならないという煩わしさがある。また、特許文献２のようにドラフトチューブの支持柱に整流板を取付けた構造ではドラフトチューブ中心付近での整流効果が乏しくなり、且つ、絡み付いた夾雑物を除去するためには、支持柱から整流板を取外して槽内から取出すことが必要となる。
【０００５】
本発明の目的は、整流板を槽外から上下に位置調整できて比較的小さな整流板で適正な整流効果が得られ、更に槽内水位に適応した有効なスカムの吸引除去が行われ、散水除去設備等を別途装備する必要がなく、また、整流板に夾雑物が絡み付いた場合には整流板のみを迅速且つ容易に槽内から引揚げることのできる、水処理槽内における竪型水中攪拌装置を提供することにある。
【０００６】
【問題を解決するための手段】
本発明の請求項１記載の水処理槽内における竪型水中攪拌装置では、槽内の支持体によって竪型のドラフトチューブを水処理槽内に支承させ、モータによって駆動される攪拌用のプロペラをドラフトチューブの上端開口部へ対向させ、水処理槽上のフロアーに開設された導下口より導下された縦杆により、攪拌用プロペラの上方において整流板が昇降自在に支承されるよう構成した。
【０００７】
また、本発明の請求項２記載の水処理槽内における竪型水中攪拌装置では、水処理槽上のフロアーに開設された導下口より導下された縦杆によって竪型のドラフトチューブを水処理槽内に支承させ、モータによって駆動される攪拌用のプロペラをドラフトチューブの上端開口部へ対向させ、攪拌用プロペラの上方において整流板が昇降自在に支承されるよう構成した。
【０００８】
更に本発明の請求項３記載の水処理槽内における竪型水中攪拌装置では、請求項１または２記載の発明を前提として攪拌用のプロペラをドラフトチューブの上端開口部へ対向させる手段として、ドラフトチューブの上端開口部と導通する攪拌機収容筒がドラフトチューブの上端縁に接続されており、竪型水中モータのモータ軸下端にプロペラを装着した攪拌機を縦杆により攪拌機収容筒内へ装脱自在に嵌装された態様とした。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vertical underwater stirring device in an anaerobic water treatment tank.
[0002]
[Prior art]
In the underwater agitator, there has conventionally been a device in which a rectifying plate for suppressing a suction vortex generated on a surface layer of a water surface of a processing tank is fixed on an outer periphery of a motor frame (for example, see Patent Document 1). In addition, there has conventionally been a device in which a straightening plate is fixed to a support column for hanging a stirrer and a draft tube into a tank (for example, see Patent Document 2).
[0003]
[Patent Document 1]
JP-A-11-342400 (FIG. 1-3)
[Patent Document 2]
JP 2000-288568 A (FIG. 2)
[0004]
[Problems to be solved by the invention]
The devices described in Patent Documents 1 and 2 have a structure in which the current plate is fixed at a fixed position and cannot be vertically adjusted, so that the current plate must be made unnecessarily large in advance, and the surface layer of the water surface is also required. As for the scum generated in the tank, effective suction removal adapted to the water level in the tank cannot be obtained. Therefore, at present, the water must be removed by showering using a separately provided watering and removing equipment. Then, in the case where the foreign matter is entangled with the current plate, in order to remove the foreign matter, in the structure of Patent Document 1, there is an inconvenience that the stirrer body has to be lifted from the inside of the tank. Further, in a structure in which a rectifying plate is attached to the supporting column of the draft tube as in Patent Document 2, the rectifying effect near the center of the draft tube is poor, and in order to remove entangled impurities, rectifying from the supporting column is required. It is necessary to remove the plate and take it out of the tank.
[0005]
An object of the present invention is to adjust the position of the current plate vertically from the outside of the tank, to obtain an appropriate rectification effect with a relatively small current plate, and to perform effective suction and removal of scum adapted to the water level in the tank. There is no need to separately install a removal facility, etc. In addition, when contaminants are entangled with the straightening plate, only the straightening plate can be quickly and easily pulled out of the tank. It is to provide a device.
[0006]
[Means to solve the problem]
In the vertical underwater stirring device in the water treatment tank according to claim 1 of the present invention, a vertical draft tube is supported in the water treatment tank by a support in the tank, and a stirring propeller driven by a motor is provided. The straightening plate is supported so as to be able to move up and down above the agitation propeller by a vertical rod guided from the lower opening formed on the floor above the water treatment tank, facing the upper end opening of the draft tube. .
[0007]
Further, in the vertical underwater stirring device in the water treatment tank according to claim 2 of the present invention, the vertical draft tube is watered by a vertical rod guided from a guide opening established on a floor above the water treatment tank. The stirring propeller driven by the motor was supported in the processing tank, and the stirring propeller was opposed to the upper end opening of the draft tube, and the straightening plate was supported so as to be able to move up and down above the stirring propeller.
[0008]
Further, in the vertical underwater stirring device in the water treatment tank according to claim 3 of the present invention, the draft propeller is provided as a means for opposing the propeller for stirring to the upper end opening of the draft tube on the premise of the invention according to claim 1 or 2. A stirrer accommodating cylinder that communicates with the upper end opening of the tube is connected to the upper edge of the draft tube, and a stirrer equipped with a propeller at the lower end of the motor shaft of the vertical submersible motor can be freely inserted into and detached from the stirrer accommodating cylinder by a vertical rod. The fitting mode was adopted.
