DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to underwater used for agitating stored water (fluid) in water tanks such as sewage treatment plants, various factories and the like, pond lakes, moats, fish farms and the like. The present invention belongs to a technical field related to a mounting posture changing mechanism for changing a mounting posture of a mixer in a water tank.

[0002]

2. Description of the Related Art Conventionally, in water tanks such as sewage treatment plants, various factories, and the like, pond lakes, moats, fish farms, and the like, in order to purify the stored water, etc. During)
It is known that a submersible mixer is installed in a submerged mixer, and the operation of the submersible mixer stirs the stored water.For example, stirring of the stored water prevents sedimentation of sludge in a sewage treatment plant, destruction of floating scum, destruction of pond lake water Thus, stagnation can be prevented. The underwater mixer includes a plurality of stirring blades provided integrally with the boss portion, and a motor having an output shaft directly connected to the boss portion, and a rotating flow of the stirring blades driven by the motor causes a swirling flow into the stored water. A blower for blowing and diffusing air into the swirling flow of the stored water in some cases is connected to the underwater mixer.

When such an underwater mixer is installed in a water tank, for example, Japanese Patent Application Laid-Open No. 2000-167375 and
As shown in each of the publications such as -170599, a guide bar (guide support) is erected so as to extend from an underwater position in the water tank to a position above the water surface, and a support base is mounted on the guide bar via a slide member. It is slidably supported, and an underwater mixer is mounted and fixed to this support base. Since a reaction force (thrust force) from the stored water acts on the guide bar when the underwater mixer is operated, the upper portion thereof is usually provided on a support bracket fixedly attached to the side wall of the water tank, and the lower portion is provided on the side wall of the water tank or the water tank. Are respectively supported by support brackets attached and fixed to the bottom surface (tank bottom).

Further, Japanese Utility Model Publication No. 3-31392 discloses that
The underwater mixer is pivotally supported (rotatable) with respect to the guide bar, and a rudder that changes the direction of water flow by the stirring blades at the front of the underwater mixer can be pivoted about a swing axis parallel to the guide bar. A tension spring is extended between the rudder and the main body of the underwater mixer to urge the rudder to tilt left or right with respect to the front-rear direction of the underwater mixer, and the rudder receives the water flow by the stirring blade. The underwater mixer receives the turning torque, and the lever is fixed to the swing shaft integrated with the rudder, and when the underwater mixer turns around the guide bar by the turning torque, the lever is attached to the bottom of the water tank. It has been proposed that the underwater mixer can perform a periodic swinging motion with a simple structure by changing the direction of the rudder to the opposite side against a fixed stopper.

[0005] In addition, it has been practiced to change the direction of the underwater mixer by supporting the guide bar itself so as to be rotatable about the vertical axis with respect to both upper and lower support brackets.

The underwater mixer is connected to a lower end of a suspension chain as a suspension member. When changing the depth of the underwater mixer, the suspension chain is raised and the underwater mixer is moved along the guide bar. The underwater mixer is moved to the target depth position by raising or loosening the suspension chain and lowering the underwater mixer along its guide bar by its own weight, and the underwater mixer is stretched by the suspension chain at that position. And hold it in a suspended state. Also, when removing the underwater mixer from the water for maintenance and inspection, lift the suspension chain and raise the underwater mixer along the guide bar to take it out of the stored water. Conversely, when submerged in the storage water, if the suspension chain is loosened, the underwater mixer moves down along the guide bar by its own weight and is held at a predetermined depth position.

[0007]

The shape, size, and depth of the water tank, the type of stored water (fluid), the purpose of stirring the water, and the like are variously different. If the installation state can be changed, the stirring effect of the stored water in these various water tanks can be enhanced, which is preferable.

However, in the above-mentioned conventional proposal, the direction of the agitated flow can be changed in the horizontal plane by swinging the underwater mixer in the horizontal direction, but cannot be changed in other directions. It was difficult to improve the stirring effect on the water.

In order to change the direction of the underwater mixer, it is also necessary to simplify the structure therefor so as to facilitate the changeover operation.

The present invention has been made in view of the above points, and an object of the present invention is to improve the mounting structure of the underwater mixer with respect to the guide bar so that the mounting posture of the underwater mixer can be easily changed with a simple structure.

The slide member supports the guide bar with the engagement members of the upper and lower rear mounting portions positioned on the rear side of the guide bar and the slide portion of the front wall of the slide member positioned on the front side of the guide bar. When the underwater mixer is in the upward position, the engaging members are respectively attached to the upper rear mounting portion and the lower front mounting portion of the left and right side walls of the slide member, and the slide member is mounted on the guide bar with respect to the upper rear mounting portion. When the underwater mixer is in a downward position, the upper front mounting of the left and right side walls of the slide member is supported in a state where the engaging member of the section is positioned on the rear side of the guide bar and the engaging element of the lower front mounting section is positioned on the front side of the guide bar. The engaging member is attached to the portion and the lower rear mounting portion, respectively, and the sliding member guides the engaging member of the upper front mounting portion to the front of the guide bar and the engaging member of the lower rear mounting portion to the guide bar. It is configured to be supported in a state where it is positioned on the rear side of the bar.

With this arrangement, the mounting posture of the underwater mixer can be changed to the horizontal posture or the upward posture only by changing the state of insertion of the guide bar in the slide member by replacing the engaging element with each mounting portion on the side wall of the slide member. And a downward attitude.

On the other hand, in the invention of claim 3, the slide member has a front wall, and a pair of left and right side walls extending rearward from the left and right ends of the front wall so as to hold the guide bar, On the front wall of the slide member, there is provided a slide portion slidably contacting the guide bar, while on the rear side of the upper and lower ends of each side wall, there are provided engagement members slidably engaged with the guide bar, respectively. When the underwater mixer is in the horizontal position, the slide member is positioned on the guide bar, the upper and lower engaging members on the left and right side walls of the slide member are both on the rear side of the guide bar, and the slide portion of the slide member front wall is on the guide bar. When the underwater mixer is in the upright position, it is supported with the front side positioned, and the slide member is positioned on the left and right side walls of the slide member with respect to the guide bar. Further, the lower engaging members are supported in a state where they are respectively positioned on the front side of the guide bar, and when the underwater mixer is in the downward position, the upper engaging members on the left and right side walls of the sliding member are arranged on the front side of the guide bar with respect to the guide bar. The lower engaging element is configured to be supported in a state where it is positioned at the rear side of the guide bar.

According to this structure, there is no need to replace the engaging element on the side wall of the slide member as in the second aspect of the present invention, and only by changing the insertion state of the guide bar in the slide member, the underwater mixer is provided. Can be changed to a horizontal position, an upward position, and a downward position.

It is configured to be suspended.

As described above, three types of locking portions are provided in the front-rear direction as locking portions of the hanging member with respect to the underwater mixer, and these locking portions are selectively used according to the position of the underwater mixer, so that the posture can be changed. Accordingly, even if the center of gravity of the underwater mixer changes, each posture of the underwater mixer can be stably maintained.

According to the fifth aspect of the present invention, the engaging element is a guide roller which is engaged with the guide bar in a rolling state. This allows the underwater mixer to smoothly move up and down with respect to the guide bar regardless of whether the underwater mixer is in a horizontal position, an upward position, or a downward position.

According to the sixth aspect of the present invention, the guide bar has a stopper for restricting the lowermost end of the underwater mixer from contacting the bottom surface of the water tank when the underwater mixer at least in the downward position is at the lowermost position. The configuration is provided. Thus, even if the underwater mixer is in the horizontal position or the upward position, or even at the lowermost position in the downward position, the stopper prevents the lowermost portion from contacting the bottom surface of the water tank. Therefore, when the underwater mixer is in the horizontal posture or the upward posture, it is possible to prevent the underwater mixer from contacting the bottom surface of the water tank in the downward posture while securing the height of the lowermost position of the underwater mixer low.
