JPH09296800A - High speed centrifugal jet flow pump - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a pump which is completely prevented from being deposited with foreign matters, and able to wash off a hot solid matter, hot wind, hot sand, an organic matter sticking to a solid matter and the like, and can be used for a vacuum pump. SOLUTION: On the opposite side to a suction side of a suction port pipe 1, grooves are cut in plural parts, while a high speed scroll chamber 3 provided with an inlet 2 is arranged in the outer circumference of the suction pipe 1. A discharge port pipe 4 provided with a conical cylinder is put on the high speed scroll chamber 3, and a double cylinder overall circumference nozzle 5 with a proper clearance is formed. When pressurized water is injected optionally from the inlet 2, a high speed scroll jet flow is generated, and a negative pressure is attained in the suction pipe 1 and the suction pump 1 functions as a pump.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to water, air, and
It is a pump that can inhale and discharge any solid that mixes with liquid or gas, fibers, ropes that are several meters long, and even if the pumping pipe and the discharge pipe are in a straight line, even a piece of rod that comes through the suction port.

[0002]

2. Description of the Related Art Conventional pumps are of a positive displacement type, a centrifugal type, a jet type, etc., but have check valves, springs, etc., which cause clogging or wrapping and are not suitable for frying solid substances mixed with water. is there. In the jet type as well, all jet nozzles are at the center of the pump or pipe, and pressure water jets out in a rod shape,
The protrusions are unavoidable, and the clogging such as stick breakage that mixes in water,
It can't be helped, and the large number of troubles at the time of jamming is a cause of high cost overall.

[0003]

Therefore, although each manufacturer spends enormous research expenses and trial production costs for pumps that do not clog, they still do not solve them. The present invention is provided to meet such a strong demand of users.

[0004]

Next, the structure of the present invention will be described. According to the present invention, several grooves are cut in the suction pipe 1 on the side opposite to the suction side, and an introduction port 2 is formed on the outer circumference of the suction pipe 1. A high-speed swirl chamber 3 with a conical cylinder is provided on the high-speed swirl chamber 3 to form a double-cylinder all-round nozzle 5 with an appropriate gap. By injecting water, a high-speed swirl jet flow is generated, the suction port pipe 1 becomes a negative pressure, and it is configured to serve as a pump.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. In FIG. 1 and FIG. 2, any pressure water guided from the inlet 2 enters the high-speed swirl chamber 3 and becomes a high-speed swirl flow, which is pressurized and accelerated by the double cylinder all-round nozzle 5 and jetted while rotating. Then, the suction port pipe 1 is made to have a negative pressure to pump water, and at the same time, the discharge port pipe 4 discharges the spouted water. The arrow in the figure indicates the direction of running water.

When a liquid or a gas is swirled at high speed,
It is typhoons and tornadoes that lower the central gas, and whirlpools in Tokushima and the Naruto Straits produce vacuum when water is turned. It has been proved by nature that a vacuum is generated by swirling a liquid like this. In fact, in the experiment, the vacuum was up to 740 mm of mercury.

[0007]

As described above, the present invention has the following advantages. As shown in FIG. 1, the high-speed spiral jet pump of the present invention has a suction port pipe 1 and a discharge port pipe 4 which are clearly aligned with each other, and the discharge port is larger than the suction port. It never gets stuck. Although it is being used for sanding in a urine input tank using a prototype experiment pump, it is well received because it will not clog at all. The pump of the present invention can also be used as a vacuum pump. Unlike mechanical vacuum pumps, since there are no rotating parts or narrow gaps, it is a so-called almighty pump that does not bite or burn even if it sucks sand, dust, hot air, etc.
