Abstract

PURPOSE:To eliminate the possibility of leakage of the fluid to be transferred, reduce operating sound and improve transfer efficiency by a method wherein a magnetic waving body, having the shape of sine wave with a given frequency, is inserted into the transfer path of the fluid and the waving body is moved by an electromagnet. CONSTITUTION:The electromagnets A, (a), A', (a') ..., opposing to the peaks and valleys of the waving body 2, contacting with the upper and lower wall surfaces of the fluid transfer path 1, are excited simultaneously, the waving body 2 is attracted strongly since it is magnetic and the peaks and valleys of the waving body 2 are abutted against the wall surfaces of the fluid transfer path 1. Subsequently, when the excitations of the electromagnets are switched sequentially in the sequence of B, C, D, ..., partitioning chambers U, V-Z are displaced to the direction of switching the excitation of the magnets. Accordingly, the fluid in the partitioning chambers U, V-Z may be transferred in the fluid transfer path 1 by the motion of the waving body 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluid transfer method for transferring various fluids using magnetic force.

Conventional fluid transfer generally uses one-way ejectors,
This has been done using mechanically coupled input methods such as reciprocating displacement pumps and rotary pumps, but in this case there is a risk of fluid leaking out of the device, and there is also a risk that the suction valve, discharge valve, etc. There are various drawbacks such as the troublesome installation required and the generation of operating noise.

The present invention has been made in order to eliminate these drawbacks of the conventional methods, and aims to provide a fluid transfer method that is free from the risk of leakage of the transfer fluid, is quiet in operation, and can improve transfer efficiency. It is something.

The present invention involves inserting a magnetic wave body in the form of a sinusoidal wave with a constant period into a fluid transfer path, and causing the wave body to wave by sequentially exciting electromagnets arranged above and below the fluid transfer path. This is a characteristic fluid transfer method, and the drawings show an example thereof. In the figure, 1 is a fluid transfer path, 2
is a wave body, and the cross-sectional shape of the fluid transfer path 1 is set to match that of the wave body 2. That is, when the wave body 2 is belt-shaped, it is rectangular (FIG. 2 (1)), and when the wave body 2 has a circular cross section, it is oval (FIG. 2 (2)). The wave body 2 is made flexible and magnetized. For this purpose, for example, a core metal 3 made of a magnetic material may be woven into a blind shape with a blind wire 4 to give it flexibility, and then covered with a rubber-like material 5 (see FIG. 3). 6.7 is a magnet array arranged above and below the fluid transfer path 1, which is made up of individual electromagnets A, B, C, D, . . . (a, b, c, d) arranged side by side. Reference numeral 8 denotes supports for maintaining the sinusoidal waveform of the wave body 2, which are installed at appropriate intervals at both ends and in the middle of the wave body 2, if necessary. Note that U and VZ are partition chambers each surrounded by the inner wall of the fluid transfer path 1 and the wave body 2, and are sequentially displaced in accordance with the wave motion of the wave body 2.

To explain the operation of the present invention, first, when the electromagnets A, a, a, etc., which are opposed to the peaks or troughs of the wave body 2 in contact with the upper and lower wall surfaces of the fluid transfer path 1 are simultaneously excited, the wave is generated. The body 2 is strongly attracted because it has magnetism, and the wave body 2
The peaks or valleys of the fluid transfer path 1 come into close contact with the wall surface of the fluid transfer path 1. Next, the electromagnet is excited by B, C, D-(b, c
, d---), the contact pressure portion of the wave body 2 against the wall surface of the fluid transfer path 1 moves accordingly. Along with this, the partition chambers (closed sections) U and VZ also shift in the excitation switching direction. Therefore, the partitions U, V
If fluid is placed in -Z, the movement of the wave body 2 can cause the fluid to be transferred within the fluid transfer path 1.

The present invention is as described above, and according to this method, the input for moving the fluid is performed by magnetic force without mechanical coupling, so there is no risk of fluid leakage, and it can be used with conventional diaphragm mechanism pumps and ejectors. The transfer capacity can be increased compared to the one-way type, there is no need for suction/discharge valves, and the operation noise is quiet.Moreover, the delivery flow rate and pressure can be changed by changing the excitation cycle without throttling valves, etc. It has an effect that can be easily changed steplessly.
