Abstract

PURPOSE: To reduce the cost of a fluid pump and simplify the structure with no need of considering a seal against fluid such as water, etc., by revolving fluid impellers by driving air impellers and pumping and leading out external fluid such as water, etc. CONSTITUTION: A fluid pump P is installed in a stand 2 which also works as a weight through an anchor 3. Compressed air is introduced into an air motor chamber 10 through a blowing-in pipe 13 from an air compressor via a blowing inlet 12, so that air impellers 11 are driven and rotated. The blown air rises through an air blowing-up route 18 and an air communicating route 21. At that time, since a rotary plate 15 is also rotated in the same direction to rotate fluid impellers 25 on the plate 15 in the same direction, outside water is sucked through a suction inlet 27 and rises as converged rising current toward the center of an apparatus and together with the air A, the water is discharged to a leading out pipe 30 from a leading out part 29.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid pump used as a drive source for fountains and water purification systems.

[0002]

2. Description of the Related Art For example, a fountain device is generally constructed so that water from a submersible pump provided separately is introduced and ejected. The submersible pump in this case has a structure in which a motor is built in and the impeller is driven to rotate, whereby water is sucked and discharged.

[0003]

In such a submersible pump, the motor and other parts are required to have a perfect sealing property against water, so that the product is considerably expensive and there is a possibility that trouble may occur. .

The present invention has been made to solve the above problems, and an object of the present invention is to provide an inexpensive and trouble-free fluid pump which does not require sealing performance against water as a drive source for a fountain, a water purification system or the like. The purpose is to provide. Further, it is also an object to accelerate the derivation of the sucked fluid.

[0005]

In order to solve the above-mentioned problems, the present invention relates to a fluid pump for sucking in and discharging a fluid such as water, the air motor having a housing including an air motor chamber and a fluid pump chamber. It has a rotatable air impeller inside and can be driven to rotate by compressed air introduced into the motor chamber, while the fluid pump chamber has a built-in fluid impeller that is driven to rotate together with the air impeller for suction. It is characterized in that an external fluid can be sucked from the mouth, and the sucked fluid can be led out from the outlet together with the air from the air motor chamber.

[0006]

Basically, the air impeller is driven to rotate the fluid impeller so that the external fluid such as water is sucked and discharged. Therefore,
There is no need to consider sealing against fluids such as water, the structure can be simplified and an inexpensive pump can be obtained, and troubles can be suppressed as much as possible. In addition, since the compressed air rises while being mixed with the fluid to be sucked in, the fluid is easily blown up by the buoyancy.

The fluid pump P is a mount 2 that also serves as a weight.
Are attached via anchors 3 ... The pump P includes a housing 4, and the housing 4 includes a lower air motor portion 5 and a fluid pump portion 6. The air motor portion 5 is provided with a fixing boss 7 at the center thereof, and a vertical axis 8 is integrally fixed to the boss 7. An air motor chamber 10 is formed on the outer peripheral portion of the boss 7.

In the air motor chamber 10, air impellers 11 ..., which are integrally formed lower impellers, are incorporated so as to be rotatable about a vertical axis 8. The air impeller 11 ... has a plane shape shown by a broken line in FIG.
It has a spiral arrangement. A blow-in port 12 is provided on the outer periphery of the housing 4, and the blow-in pipe 1 is provided in the blow-in port 12.
3 is connected. A land-based air compressor 14 shown in FIG. 3 is connected to and connected to the blow-in pipe 13.

A rotary plate 15 is provided with the air impellers 11 ... on its lower surface. The plate 15 is located on the outer periphery of the rotary boss 16 in the center and the rotary boss 16 is provided.
The air blow-up passages 18 ... Are opened between the ribs 17 via the ribs 17. The air after driving the air impeller 11 ...
Blow up like arrow A of. The air may be introduced from another peripheral portion of the housing 4 as indicated by a phantom line A in FIG.

The rotary boss 16 is rotatably supported by a bearing 20 about the vertical axis 8. An air communication passage 21 is formed on the outer periphery of the boss 16 so as to communicate with the upper portion of the air blowing passages 18 ... Further, a fluid impeller 25 is integrally arranged on the outer peripheral side of the communication passage 21 via the upper surface of the rotary plate 15, and is rotationally driven in the fluid pump chamber 26.

The fluid pump chamber 26 has a suction port 27 from the outside.
... are communicated with each other, and the suction port 27 is opened as a port communicating with the inside and outside between the vertical ribs 28 that vertically connect the housing 4.

The fluid impeller 25 ...
As shown in FIG. 3, water is introduced from the outside to form an upward flow toward the center of the apparatus together with the air A, and the water is guided from a lead-out portion (having a lead-out port at the upper end) 29 through a lead-out pipe 30.

Compressed air from the air compressor 14 is introduced from the blowing pipe 13 into the air motor chamber 10 through the blowing port 12, whereby the air impellers 11 ... Are rotationally driven in the direction of arrow X in FIG. The air rises through the air blowing passage 18 and the air communication passage 21 as indicated by arrow A. On the other hand, the rotary plate 15 is also rotated in the same direction X, and the fluid impeller 25 on the rotary plate 15 is also rotated in the same direction. As a result, external water is sucked in through the suction ports 27, ... And the air A is led into the lead-out pipe 30 from the lead-out portion 29.

For convenience of assembly and disassembly, the housing 4 can be vertically combined and separated with a portion corresponding to the vicinity of the upper surface of the rotary plate 15 as a boundary. Further, the air A may be made to rise along the outer periphery of the fluid impeller 25.
