Abstract

PURPOSE:To permit the up-and-down motion of a vibrating tube in order to effect pumping without utilizing an impeller or the like by a method wherein the lower end of a vibrating tube is connected to the upper end of a fixed tube provided uprightly so as to submerge the lower end thereof into water while a valve plate, pressing the upper end of the vibrating tube in a liquid guide tube, is provided. CONSTITUTION:One part of the vibrating tube 4, which is penetrating through the liquid guide tube 8, is sealed so as to be capable of vibrating into the longitudinal direction thereof by a vibrator 5 while the lower end thereof is coupled by the flexible coupling to the fixed tube 2 whose lower end is submerged into water. The inner diameteral side of a bellows 9 is fixed to the vibrating tube 4 while the outer diametral side thereof is fixed to the liquid guide tube 8. The upper end of the vibrating tube 4 is utilized as a valve seat 10 and the valve plate 11, resiliently pressing the valve seat, is provided. According to such constitution, pumping and discharging of the liquid may be permitted without utilizing a rotary part such as the impeller or the like by repeating the up-and- down motions of the vibrating tube 4, which are effected by the vibrator 5.

Description

[Detailed description of the invention] The present invention relates to a pump.

Conventionally, many pumps have been produced that pump liquid by rotating an impeller, but many parts are immersed in the pumped liquid, and from the viewpoint of corrosion, the pump O1 does not have complicated moving parts inside! There was a request.

An object of the present invention is to provide a pump that has fewer moving parts and fewer parts that are immersed in pumped liquid.

The present invention provides a pump based on a completely new principle that has not existed before. A vibrating tube is placed above a fixed tube with one end immersed in water and the other end in the air, and the lower end of the vibrating tube is movable. The flexible pipe joint is sealed and connected to a fixed pipe, and the upper end of the vibrating pipe is sealed and inserted into a hollow liquid guide pipe, and the end protruding into the liquid guide pipe is used as a valve seat and attached to a spring. The energized valve plate is brought into contact with the vibrating tube, the liquid guiding pipe is provided with a discharge port to the discharge pipe, and a vibrating means is arranged so as to vibrate in the longitudinal direction Ki6 of the vibrating tube. be.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view.

A fixed tube whose lower end is submerged in the open liquid surface l and which is open at both ends is fixed to an immovable part and is connected to the upper end of the fixed tube through a flexible joint 3 in a sealed manner to a pipe-shaped vibrating tube 41. The vibrating pipe is supported so as not to be allowed to move in the vertical direction by the output part 4 of the vibrator j installed as a stationary part #C which rotates a co-rotating body having an unbalanced weight, thereby causing vibration. Although the zero vibration exciter j is not limited, it must be one that generates vibrations in the vertical direction.

The upper part of the vibrating pipe is at least inserted with a fixed liquid guide pipe t which is shaped like a container and has a discharge lower. The part where the vibrating tube passes through the liquid guide tube t is sealed with a seal so that the vibrating tube allows vibration in the longitudinal direction of the tube. The side is a vibrating tube e
K is fixed, and the outer diameter hook is fixed to the liquid guide pipe XI/C.

In the liquid guiding pipe l, the vibrating pipe protrudes so that the leading end is at an intermediate position, and a valve plate // is filled with one end of the vibrating pipe as a valve seat 10.
A spring 13 is compressed and inserted into a spring seat/J fixed on the valve plate // and the liquid guide pipe l. It is appropriate that the round end portions of both ends of the spring /J are fixed to the valve plate /i and the spring dust 12Yc (the fixing method is not shown).

Figures JIII to 1 are schematic longitudinal cross-sectional views of a detailed embodiment of the present invention.

When the vibrator 1 is energized, the output section 6 moves up and down, causing the vibrating tube to move up and down.

■ When the vibrating pipe moves downward in Fig. 2, the valve plate /l does not follow it but moves downwards, and at the upper end, the vibrating pipe and the valve plate /101%15 are slightly separated. A gap is created. At this time, the air inside the vibrating tube escapes to the top.

When the vibrating tube moves downward, the valve plate catches up and closes the valve seat 10, as shown in FIG.

When the vibrating tube l with the valve opening closed (by the θ valve @/ / ) rises, the air in the vibrating tube and the fixed tube λ expands, and the O pressure in both tubes decreases (Figure 1).

Furthermore, when the vibrating tube is lowered, the liquid in the vibrating tube and the fixed tube will not go down (due to the inertia of the liquid). Therefore, at this time as well, gas is discharged to the top, the pressure inside the vibrating tube and the fixed tube decreases, and the liquid rises.

Due to this action, pressure fluctuations caused by the vibrating pipe or valve plate are transmitted to the liquid when it is full of liquid, and to the gas when it is not filled, and the A standing wave of pressure is generated in the liquid, and the pressure standing wave has a large fluctuating pressure at the valve plate // and decreases at the lower part of the fixed pipe. (Liquid or gas escapes to the upper part from between 7. In the same way, by returning the state of When the liquid flows down the liquid guide pipe l
The liquid overflows into the interior and flows through the liquid guiding pipe from the inside toward the discharge direction, and then the liquid is pumped up and discharged.

Figure 1gj is a longitudinal sectional view of another embodiment of the present invention. In this embodiment, the excitation means of the previous embodiment is changed to an electromagnetic coil. Insert the vibrating tube through the center of the DC electromagnetic coil/4+ provided in the stationary part.

The whole or a part of the vibrating tube l is made of a magnetic material, and its upper part is supported by a bellows in a sealed manner with respect to the liquid guide tube tK. Then, the direction of the current is alternately changed and the electromagnetic coil is energized to give vertical movement to the vibrating tube.The operation of this embodiment is similar to that of the first embodiment.

FIGS. 6 and 7 are longitudinal sectional views of still another embodiment O of the present invention. The diameter of the fixed pipe and the vibrating pipe can be changed to 4m, which can change the loss of the pipe! By making the diameter of the fixed tube larger than the diameter of the vibrating tube q,
Reduce piping loss (Fig. 6)
Therefore, the loss will be larger, but the price will be lower (Figure 7).

As described above, in the vibrating column pump of the present invention, the lower part of the vibrating tube equipped with vertical vibration means is connected via a flexible joint to the upper end of a fixed tube that is erected with one end submerged in water. Since the valve plate is placed in the liquid guide pipe and the upper end is the valve seat, and the valve plate is pressed against the valve seat, there is no need for a rotating part such as a vane wheel for pumping the liquid, and it is possible to use only one vibrating pipe. The structure is simple. For this reason, special materials can be used, so it can also be used for pumping liquids that are prone to corrosion.

Additionally, since there are no sliding parts with high circumferential speed like in bearings, it is also advantageous in terms of wear resistance.

Even if there is corrosion, it is easy to replace.
