Description

[Detailed Description of the Invention] The present invention provides a water tank that stores raw conslurry 1, water containing lime, etc., or water with a large amount of sediment such as sewage.
The present invention relates to a fluid stirring device that suspends and stirs sediment.

Conventional fluid agitation devices have the disadvantage that the agitation force is not widely dispersed from the periphery of the machine to the bottom of the water tank, but instead changes into an upward flow, and the dispersion is also poor, making it impossible to suspend sediments sufficiently. there were.

The present invention was created in consideration of the current situation, and its purpose is to provide a fluid agitation device that eliminates the above-mentioned drawbacks, floats precipitates quickly and powerfully, and can achieve sufficient agitation effects. That is.

In this invention, the output shaft of a submersible motor with an impeller fixed to it is surrounded by a pump casing that has an inlet at the lower end and a discharge outlet on the circumference, and the mounting position and number of the outlet can be changed. The present invention relates to a fluid stirring device characterized by the following features.

An embodiment of the fluid stirring device according to the present invention is specifically shown in FIGS. 1 to 7, and 2 in the figure is a completely waterproof submersible motor with an output produced by fixing an impeller 1. It is placed underwater with the shaft 3 facing downward.

A pump casing 6 is attached to the lower surface of the submersible motor 2 so as to surround the output shaft 3 and the impeller 1 concentrically, and the casing has an inlet 4 at the center of the lower surface and a - Alternatively, two or more sets of discharge ports 5 are provided as shown in FIGS. 4 to 7.

A porous strainer 7 having through holes of a required diameter is further connected to the lower surface of the casing 6 as necessary, and is supported by a machine frame 8 on the bottom surface of the water tank.

Regarding other structural features of the above embodiment, reference numeral 10 denotes a jet nozzle which is flange-coupled to the discharge port 5 of the pump casing 6. By changing the direction of ejection, the direction of ejection can be freely changed.

Furthermore, a flexible hose 11 of a required length can be attached to the extended end of the jet nozzle 10 or in place of the jet nozzle. In that case, the flexible hose 11 receives the reaction force of the water and acts like a snake writhing in the water. Since it moves, it is possible to give more freedom in the direction of ejection.

Note that 12 is a power cable. Next, the operation of the fluid stirring device according to the present invention will be described.

First, the agitation device according to the present invention is placed in a water tank containing a lot of sediment, allowed to settle, placed on the bottom of the tank, and then the submersible motor 2
to drive.

This driving causes the impeller 1 connected to the output shaft 3 to rotate.

Then, as the impeller 1 rotates, water around the strainer 7 passes through the porous strainer 7 and the suction port 4 together with the sediment accumulated under the strainer 1 to the strainer 7 to the pump casing 6.
After that, the discharge port 5 and the jet nozzle 10
And/or the water sucked through the flexible hose 11 is spouted in a predetermined direction within the tank (toward the floor, in a direction parallel to the floor, upward, etc.) to generate strong agitation within the tank.

For this purpose, the jet nozzle 10 can freely select the jet direction by changing the mounting position of the jet nozzle 10 relative to the flange of the discharge port 5, as shown in FIG. 1, FIG. 2, or FIGS. 4 to 7. The jet can be sprayed evenly throughout the tank or only in areas where sediment is particularly heavy, and when the flexible hose 11 is attached, the jet direction within the tank can be made random, and the sediment on the bottom surface below the device can be spouted. Immediately floats sediment evenly not only on objects but also on the entire bottom surface of the aquarium,
Furthermore, it is possible to maintain the floating and mixed state so that it does not re-sediment.

As described above, the fluid agitation device according to the present invention can forcefully suspend sediment, etc. over the entire bottom of the tank by simply rotating the impeller, and can also suspend only specific sediment areas. Furthermore, reprecipitation can be effectively prevented.
