Abstract

PROBLEM TO BE SOLVED: To prevent a passage in a rotor from being blocked even if foreign matters is contained, by supporting the rotor to a pump casing so that a suction port may face a suction passage for soil water of the pump casing, and forming a pumping passage on the pump casing so that it may face a discharge port of the rotor. SOLUTION: Soil water is sucked from a suction port 2a into a passage 2 through a suction passage 5 by rotating a rotor A, discharged from a discharge port 2b into a rotor chamber 10, and discharged from a pumping passage 11 outside a machine. At this time, since the suction port 2a of the rotor 2 and the suction passage 5 are faced to each other, soil water from the suction passage 5 is allowed to smoothly flow to the passage 2 in the rotor A, and it is allowed to flow by smoothly changing its direction to the outer peripheral direction since there is one passage 2. Accordingly, the passage is not blocked by clogging of foreign matters even if there are foreign matters in the soil water, and any gravel is not accumulated in the passage 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a non-clog pump used for sewage containing many contaminants such as sewage.

[0002]

2. Description of the Related Art Conventionally, as a non-clog pump of this type, a blade having a hollow tube bent into a tongue shape, having a suction port opened at its center and having left and right ends thereof as discharge ports is used. There is something I had. (See Fig. 2)

[0003]

However, in the conventional B-shaped blade, since the sewage sucked in at the center is divided into the left and right directions, the contained impurities cannot be smoothly separated and flow,
There was a problem that the flow was disturbed and clogged at this branch part.
In addition, the shape of the blade is also a tongue and is unstable, and there is a problem in that it causes vibration and the like.

[0004]

The present invention solves the above-mentioned problems by using a rotor provided with a single suction flow path, and the gist of the invention is to provide a disk. In the center of the main body of solid wood, the suction port is opened, and the discharge port is bent in the main body in a radial direction to form a rotor having a flow path that opens at the outer peripheral surface of the main body. The suction port is supported by the pump casing so as to face the dirty water suction passage of the pump casing, and a pumping passage is formed in the pump casing so as to face the discharge outlet of the rotor.

[0005]

The non-clog pump according to the present invention is configured as described above, and by rotating the rotor, the dirty water sucked from the suction port is sent to the outer peripheral direction of the rotor by the centrifugal force and pumped from the pumping channel. To be done. At this time, since the sewage sucked into the rotor has only one flow path, it flows smoothly in only one direction, and therefore, the flow path in the rotor may be blocked even if it contains impurities and the like. Absent.

[0006] Further, although only one flow path is provided and asymmetric with respect to the shape of the rotor, since the rotor itself is made of solid material, it can be constructed by bending a conventional cylindrical body. In comparison, it has a large inertial force, acts like a flywheel, sufficiently absorbs vibrations, etc., and is far superior in strength. Hereinafter, the present invention will be specifically described with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a rotor of a pump according to the present invention taken out and shows an elbow-shaped flow passage 2 formed inside a disc-shaped main body 1. In this flow path 2, a suction port 2a is opened on the center side surface of the main body 1, and a discharge port 2b is opened on the peripheral surface of the main body 1. FIG. 2 shows a blade B of this type of conventional non-clog pump taken out and shown. The cylindrical main body is bent into a toe-like shape to open a suction port at the center thereof, and the sewage sucked from this opening is left and right. It is made to flow in the cylinder by being divided into two parts, and is discharged from the outer opening.

Next, FIG. 3 shows a state in which the rotor A is assembled in the casing 3 of the pump. In the figure, reference numeral 4 is a pump casing cover, and 5 is a waste water formed in the casing cover 4. It is a suction path and faces the suction port 2a of the rotor A. Reference numeral 6 denotes a support shaft of the rotor A, which is connected to the drive shaft 8 of the motor 7 and is supported by the casing 3 by the bearing 9. Reference numeral 10 indicates a rotor chamber, and 11 indicates a pumping channel.

The pump according to the present invention is constructed as described above, and by rotating the rotor A, the dirty water is sucked from the suction port 2a into the flow channel 2 through the suction passage 5, and the discharge port 2b. Discharged into the rotor chamber 10 from the pumping channel 1
It is discharged from the aircraft from 1.

At this time, since the suction port 2a of the rotor 2 and the suction passage 5 are opposed to each other, the dirty water from the suction passage 5 smoothly flows into the passage in the rotor, and after the inflow, the passage 2 also. Since there is only one, the flow smoothly changes direction to the outer circumference. Therefore, even if contaminants are present in the dirty water, they are not clogged and clogged, and gravel and the like are not accumulated in the flow path.

Further, in the present invention, the single flow passage 2 corresponding to the blade of the pump is asymmetrical, but the flow passage 2
Since the rotor A that is equipped with is made of solid wood,
The rotation causes a large inertial force, completely absorbs vibrations and the like due to the asymmetrical shape of the flow path 2, and operates smoothly. Further, since the flow path 2 is formed in a disk-shaped solid material, it has strength, can rotate at high speed, can generate a large centrifugal force, and can be a high-performance pump. it can.

[0012]

As described above, the present invention solves the problems of blockage and unstable operation of the conventional non-clog pump of this kind, and realizes a high-strength and high-performance non-clog pump. .
