Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an installation device for a submersible blower in which suction and discharge piping are fixed on land and the blower body is immersed in water.

Recently, for purposes such as cooling and noise prevention, blowers in which at least one of the blowers is immersed in water to exhaust or blow air have begun to be used.

However, the blower itself must be removed from the tank from time to time for inspection, maintenance, lubricating oil changes, etc.

In this case, if only the tip of the suction pipe protrudes into the air and the discharge pipe is immersed in the water together with the blower body, such as for aeration in a sewage tank, the entire body including the suction and discharge pipes should be able to be raised and lowered as a unit by an appropriate guide. However, if the suction and discharge pipes are fixed on land and require suction and discharge between the aquarium and a remote location, the blower and piping can be raised and lowered as a unit, as in the aeration system described above. I can't.

That is, it is necessary to connect or disassemble the suction and discharge pipes on land.

In view of the above-mentioned circumstances, the present invention has been developed by forming an intermediate pipe for suction and discharge with a tip part protruding into the air integrally with a blower main body, and lowering the integrated pipe into the water by simply moving it up and down with an appropriate guide. This relates to an installation device for a submersible blower that automatically connects the intermediate piping and the suction/discharge piping on land in close contact with each other when the pipe is connected to the submersible blower. The purpose of this invention is to provide a simple device that can be attached to and detached from the device.

To describe the embodiment in the figure in detail, 1 and 2 are suction piping and discharge piping, respectively, which are placed on land and fixed on a common platform 3.
In both cases, the tips on the blower side protrude above the water tank 4 and are bent upward, and flanges 1a and 2a are provided horizontally at the open ends with appropriate pitches.

5 is a silencer installed at the other end of the suction pipe 1, and 6 is the discharge pipe 2.
This is a safety valve installed in the middle.

Reference numeral 7 denotes a guide rod, which includes upper brackets 8, 8 provided on the side of the common platform 3 and a lower bracket provided on the side wall 4a of the water tank 4, so as to be located directly below the protruding ends of the suction/discharge pipes 1, 2. 9, 9, the two are fixed in a parallel upright manner with an appropriate interval between them.

10 is a motor 11. This is a submersible roots blower in which a blower 12 is directly connected in a watertight manner, and the intermediate pipes 13 and 14 connected to the suction port and the discharge port are extended upward and bent into an inverted U shape, respectively. Flanges 13a and 14a having downward horizontal opening surfaces are provided at the same pitch as the flanges 1a and 2a of the suction and discharge pipes, and these intermediate pipes 13 and 14 have common flanges 15 and 1 at the upper part.
6 and two connecting plates 17, and two lifting rings 18 are provided at the top.

Furthermore, the submersible roots blower 10 is fixed to the motor 11 and an upper guide fitting 19 that connects intermediate pipes 13 and 14 that are formed to be slidably fit between the two guide rods 7, 7. A lower guide fitting 20 is provided, and the lifting rings 18, 18 can be lifted up and down along the guide rods 7, 7 using a suitable chain block or the like for suspending them.
14a are automatically abutted against each other and tightly connected by the weight of the entire Roots blower 10.

In this case, as shown in FIG.
If a cushioning packing material such as No. 1 is used, the sealing performance of the iron part will be perfect.

The submersible roots blower 10 has a flange 13a,
Ideally, the center of gravity should be placed approximately midway below the line connecting 14a, and one guide rod should be square, or a round guide rod with a key-shaped detent as appropriate. It may be a set-up.

As detailed above, when using the device of the present invention, even if the suction/discharge piping is installed on land, only the submersible blower with motor and the intermediate piping can be raised and lowered as a unit, and connecting members such as bolts and nuts are used. The blower can be closely connected to the piping section installed on land without any trouble, and inspection and maintenance of the blower itself can be performed extremely easily.

[Brief explanation of the drawing]

Figures 1 to 3 show an embodiment of the device of the present invention, of which Figure 1 is a side view, Figure 2 is a front view, and Figure 3 is a sectional view taken along the line A-A in Figure 2. Figures 4 and 4 illustrate various sealing means in the flange portion. In the figure, 1 and 2 are suction and discharge pipes, 7 is a guide rod, 10 is a submersible roots blower 113, 14 is an intermediate pipe, 19,
Reference numeral 20 indicates upper and lower guide fittings.

Claims (1)

[Scope of Claims] 1. In a structure in which the suction and discharge piping is fixed on land and the blower main body is submerged in water, the blower side end of the suction and discharge piping has an upwardly opening shape with the flange surfaces arranged in parallel with appropriate pitches, and is connected to the water tank. A guide rod is provided between these flanges, which is fixed to the water tank wall surface with an appropriate bracket, and is connected to the blower and the suction/discharge port of the blower, and is extended upward by an appropriate length to connect the tip flange. An integral piece of intermediate piping, each having a downward opening and the pitch of both flanges being the same as the tip flanges of the suction and discharge piping, is connected to the guide rod and an appropriate number of guide fittings fixed at appropriate positions on the integral piece. The blower is configured so that it can be moved up and down non-rotationally by engagement, and when the blower is in a lowered state, the flanges of the suction/discharge piping and the intermediate piping are automatically tightly connected by the weight of the blower integrally. Installation equipment for submersible blowers. 2. The submersible blower installation device according to claim 1, wherein the guide rods are provided in two in parallel. 3. An installation device for a submersible blower according to claim 1, wherein said guide rod is a single guide rod and is provided with appropriate rotation prevention means. 4. An installation device for a submersible blower according to claim 1, wherein the integrated blower and intermediate piping have a center of gravity located approximately halfway below a line connecting both flanges at the tip of the intermediate piping. 5. The submersible blower installation device according to claim 1, wherein a cushioning seal member is interposed on the flange surface of the suction/discharge piping.
