この発明は、水中に気泡を拡散させるようにしてなる、
ポンプ装置に関する。[Detailed Description of the Invention] This invention is made by diffusing air bubbles in water.
It relates to a pump device.
従来、微生物を利用した汚水処理装置の処理槽や、養魚
池などにおいて、水中に酸素を溶存させるため、気泡を
拡散させることは周知である。BACKGROUND ART Conventionally, it is well known that air bubbles are diffused in order to dissolve oxygen in water in treatment tanks of sewage treatment systems that utilize microorganisms, fish ponds, and the like.

一挙に解決しうるポンプ装置を、簡単な構成で提供しよ
うとするものである。However, in order to diffuse air bubbles into the water in this way, an intake pipe that can be expanded and contracted up and down is installed in a water tank equipped with a gas inlet, and a gas-liquid pipe that drives a rotor installed at the lower end of the intake pipe is installed. A liquid gas processing device in which an air supply is provided in the center of a contact device (publication of Utility Model Publication No. 45-1284) and a container, and radial blades provided at the lower end of the container are driven by an electric motor provided outside the container at the lower end of the container. (Japanese Unexamined Patent Publication No. 50-93866) is known, but it is not sufficient to generate a large number of fine bubbles, that is, to make the bubbles finer. Therefore, the present invention aims to provide a pump device with a simple configuration that can solve these problems all at once.

A mounting lug 2b is provided on the reaction force extraction shaft side of the submersible motor 2. The power extraction koji side of the casing of the submersible motor 2 is shaped into a conical shape 2c.

種々選択しうるものである。The expansion and contraction of the cylinder 1' is adjusted by means not shown so that its upper end ld is located slightly below the water surface WL. Next, when the diving motor 2 is operated, the rotating shaft 3 rotates in the direction of the arrow shown in the figure. Then the impellers 4a, 4
Due to the force generated by b, the water level inside the cylinder 1 lowers, and the water falls into the cylinder 1 from the upper end la of the cylinder 1. As this falls, relatively large bubbles B appear in the water inside the cylinder 1.
1 is generated and falls together with the water sucked by the impellers 4a and 42. First, a large bubble B is created by the impeller 4b.
I is crushed and made fine, and further made fine by the impeller 4a, and becomes microbubbles B2. At this time, the temperature of the water increases due to the heat generated by the submersible motor 2, which reduces the surface tension of the water and promotes the miniaturization of bubbles. Particularly in the case of sewage treatment, the activity of microorganisms increases, which shortens the treatment time. The size of the bubble B2 can easily be set to about 0.1 rib. As the water flow is guided by the conical shape 2c, the bubbles B2 spread laterally and rise. Thus,
This results in a large amount of oxygen remaining in the water. In addition to the embodiments described above, the number of impellers may be three or more, and the number of blades of the impeller, its rotation speed, etc. can be variously selected depending on the specifications of the purpose.

りであるので、下記する顕著な効果を奏する。That is, for example, a multi-tube type sewage treatment device is constructed by attaching a multi-tube body (for example, a cylindrical tab, a honeycomb, etc.) around the cylinder 1 of the device according to the present invention so that water can flow in the vertical direction. In the case of the form in which it is used, it is advantageous to increase the flow rate of the treated water that passes through the multi-tubular body (conventionally, a lift pump that releases air from a separate valve inside the cylinder) is used. (Because the treated water was being circulated, the flow rate was slow.) It was necessary to increase the tin content using impellers, and the number of impellers would also increase. If the pond is shallow and wide, as in the case of a fish pond, two impellers may be sufficient, since tin is not needed as much. It may also be effective in some cases to form the upper end of the cylinder 1 into a bell mouth. In particular, the upper impeller 4b may have a shape that has an excellent function of breaking up air bubbles rather than generating air bubbles. Further, the shaft 3 may be supported not only on one side but also on its tip. In any case, in the experiment in the embodiment shown in FIG. 1, the aeration efficiency was approximately 0.3 to 0.5. However, the following formula applies. Since this invention is as described above, it has the following remarkable effects.

の気泡の微細化が助長される。By providing at least two spiral impellers slightly above and below, not only can a large number of fine bubbles be generated, but also by providing them at the lower end of the cylinder, the miniaturization of the bubbles is facilitated by the rise in water temperature due to the heat generated by the submersible motor.
