Description
【０００１】
【発明の属する技術分野】
この発明は、汚泥等の発酵槽における原料の撹拌装置の改良に関し、特に、この発明では、発酵槽がループ状に構成されていて、撹拌装置がその円形部で旋回する必要がある発酵槽において、円形部で原料を均一に撹拌することができる装置を提供せんとするものである。
【０００２】
【従来の技術】
従来、平面的にみて長手方向中心線上を中間仕切壁で仕切られてループ状に形成された発酵槽内をスクープ式の撹拌装置が巡回し、槽内の原料を撹拌しながら搬送して発酵させる装置は公知である。特開平８−６７５８８号公報はその一例である。この特開平８−６７５８８号公報では、台車に載架した撹拌装置が発酵槽の直線部では往復動し、円形部では、その内端部を中心にして旋回するようにしている。
【０００３】
【発明が解決しようとする課題】
然しながら、上述のような発酵槽内を撹拌装置が作動しながら巡回するものでは、撹拌装置を円滑に移動させるために発酵槽の側壁と撹拌装置の機枠との間に隙間が必要である。特に、撹拌装置が旋回する部位では、撹拌装置のスクープにかかる負荷が不均衡となるため、直線移動部よりも大きな隙間が必要である。
【０００４】
また、撹拌装置が旋回するときには、スクープが旋回中心部の原料を槽内外周部に向って放擲するので、旋回中心部にすり鉢状の凹みを生ずる。この凹みに向って前述放擲した原料が上記隙間を通って逆流し、これを再度掬い上げて撹拌することとなる。すなわち、従来装置では、撹拌装置の旋回部において、原料の偏位と撹拌済の原料の逆流によって均一な撹拌ができない。
【０００５】
【課題を解決するための手段】
この発明は、上述後段の放擲した原料の逆流を完全に防止し、原料を均一に撹拌混合できるようにしたものであって、その要旨とするところは、平面的にみて長手方向中心線上を中間仕切壁で仕切られてループ状に形成された発酵槽に、槽底部の原料を掬い上げて後方に放擲しながら槽内を巡回するスクープ式撹拌装置を設けた発酵装置において、スクープ式撹拌装置Ａの内側機枠には、旋回部におけるスクープ式撹拌装置Ａの旋回中心軸と平行方向にスクレーパー３を固定し、該スクレーパー３の内端縁が旋回部及び直線移動部において中間仕切壁４ａの壁面に摺接させたものである。
【０００６】
【発明の実施の形態】
この発明に係る装置は、上述のように構成してあるので、撹拌装置が旋回時にスクレーパーの内端縁が中間仕切壁面に摺接し、撹拌装置の内端面と中間仕切壁面との間の隙間を密閉する。従って、放擲した原料が逆流して再混合することがなく、旋回部においても原料を均一に撹拌することができる。以下、図面に基づいてこの発明を具体的に説明する。
【０００７】
【実施例】
図１は、この発明に係る撹拌装置の側面図であり、図中、符号１は、多数のスクープ１ａを装着した無端状のスクープベルト、２は、スクープベルト１の左右の側部および後方部を覆うカバー、３は、スクープベルト１の内端側のカバー２に装着したスクレーパーであり、その内端縁３ａが図２および図３に示すように発酵槽４の中間仕切壁４ａの壁面に接触させてある。
【０００８】
また、前述スクープベルト１の上端は、駆動軸５に巻回してあり、この駆動軸５は、図２に示すように旋回台７に搭載した駆動機８にチェーン８ａで連結してある。そして、撹拌装置Ａの旋回中心は図３に示すように中間仕切壁４ａの中心線Ｘ上に位置させてある。
【０００９】
この発明に係る撹拌装置Ａは上述のように構成してあり、図４に示すような平面的にみて長手方向中心線上を中間仕切壁で仕切られてループ状に形成された発酵槽４内を巡回して、槽内の原料を図５に示すように掬い上げ、後方に放擲して撹拌すると同時に移送する。このとき、撹拌装置Ａの旋回部では、その旋回中心部分の原料が後方外周部に向って放擲され、旋回中心部分にくぼみが生じ、このくぼみに向って放擲した原料が逆流せんとする。（図６参照）このとき、この発明では、原料が逆流せんとする隙間にスクレーパー３が設けられているので、この放擲原料の逆流を阻止することができる。
【００１０】
すなわち、撹拌装置Ａの旋回部で放擲原料の逆流を阻止して、発酵槽４内全体で均一な撹拌をすることができるものである。なお、撹拌装置Ａの直線移動部でもスクレーパー３が中間仕切壁４ａに摺接するので、原料の逆流が阻止され、この部位でも均一な撹拌が可能なものである。
【００１１】
【発明の効果】
このように、この発明に係る装置によれば、スクープ式の撹拌装置を有する発酵装置において、放擲原料の逆流を完全に防止して均質な発酵製品を得ることができるとともに、その発酵状態の管理を容易にしたものである。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a stirring apparatus for raw materials in a fermenter such as sludge. In particular, in the present invention, in a fermenter in which the fermenter is configured in a loop shape and the stirring apparatus needs to be swung in its circular portion. The present invention intends to provide an apparatus capable of uniformly stirring the raw material in the circular portion.
[0002]
[Prior art]
Conventionally, a scoop-type stirrer circulates in a fermentation tank formed in a loop shape by dividing the center line in the longitudinal direction by an intermediate partition wall in a plan view, and transporting and fermenting the raw material in the tank while stirring The apparatus is known. JP-A-8-67588 is an example. In JP-A-8-67588, a stirrer mounted on a carriage reciprocates in a straight part of a fermenter, and in a circular part, it turns around its inner end.
[0003]
[Problems to be solved by the invention]
However, in the case where the agitator is circulated in the fermenter as described above, a gap is required between the side wall of the fermenter and the machine frame of the agitator in order to move the agitator smoothly. In particular, at the site where the stirring device turns, the load applied to the scoop of the stirring device becomes unbalanced, and therefore a larger gap than the linear moving part is required.
[0004]
Further, when the stirring device is swung, the scoop dissipates the raw material in the swivel center toward the inner peripheral portion of the tank, so that a mortar-shaped dent is generated in the swivel center. The raw material released in the direction of the dent flows backward through the gap, and is again scooped up and stirred. That is, in the conventional apparatus, uniform stirring cannot be performed due to the deviation of the raw material and the backflow of the stirred raw material in the swirling part of the stirring device.
[0005]
[Means for Solving the Problems]
The present invention completely prevents backflow of the above-mentioned released raw material, and allows the raw material to be uniformly stirred and mixed. The gist of the present invention is that on the longitudinal center line in plan view. In a fermenter provided with a scoop type agitator that circulates inside the tank while scooping up the raw material at the bottom of the fermenter that is partitioned by an intermediate partition wall and formed in a loop, The scraper 3 is fixed to the inner machine frame of the device A in a direction parallel to the turning center axis of the scoop type stirring device A in the turning portion, and the inner edge of the scraper 3 is an intermediate partition wall 4a in the turning portion and the linear moving portion. It is slidably contacted with the wall surface .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Since the apparatus according to the present invention is configured as described above, the inner end edge of the scraper is in sliding contact with the intermediate partition wall surface when the agitator is turning, and a gap between the inner end surface of the agitator device and the intermediate partition wall surface is formed. Seal. Therefore, the released raw material does not flow back and remix, and the raw material can be uniformly stirred even in the swivel section. The present invention will be specifically described below with reference to the drawings.
[0007]
【Example】
FIG. 1 is a side view of an agitation device according to the present invention. In FIG. 1, reference numeral 1 denotes an endless scoop belt equipped with a number of scoops 1a, 2 denotes left and right side portions and rear portions of the scoop belt 1 The cover 3 is a scraper attached to the cover 2 on the inner end side of the scoop belt 1, and the inner end edge 3a is formed on the wall of the intermediate partition wall 4a of the fermenter 4 as shown in FIGS. It is in contact.
[0008]
The upper end of the scoop belt 1 is wound around a drive shaft 5, and this drive shaft 5 is connected to a drive unit 8 mounted on a swivel base 7 by a chain 8a as shown in FIG. And the turning center of the stirring apparatus A is located on the centerline X of the intermediate partition wall 4a as shown in FIG.
[0009]
The stirrer A according to the present invention is configured as described above, and the interior of the fermenter 4 formed in a loop shape is partitioned on the center line in the longitudinal direction by an intermediate partition wall as seen in a plan view as shown in FIG. It circulates and the raw material in a tank is scooped up as shown in FIG. At this time, in the swirl part of the stirring device A, the raw material in the swivel center part is dissipated toward the rear outer peripheral part, and a recess is generated in the swivel center part, and the raw material dissipated toward this recess is a reverse flow. . (Refer to FIG. 6) At this time, in the present invention, since the scraper 3 is provided in the gap where the raw material flows back, the back flow of the raw material can be prevented.
[0010]
That is, the swirl of the stirrer A can prevent the backflow of the raw material to be stirred uniformly throughout the fermenter 4. In addition, since the scraper 3 is in sliding contact with the intermediate partition wall 4a even in the linear moving portion of the stirring device A, the back flow of the raw material is prevented, and uniform stirring is possible even at this portion.
[0011]
【The invention's effect】
Thus, according to the apparatus according to the present invention, in the fermentation apparatus having a scoop type stirring apparatus, it is possible to obtain a homogeneous fermented product by completely preventing the back flow of the raw material, and in the fermentation state. It is easy to manage.
