[0014]
[Action]
[Liquid purification device of claim 1]
[0015]
First, the operation of the parts common to the conventional liquid purification apparatus will be described.
[0016]
In use, the liquid purifying apparatus of the present invention can be used, for example, to convert the liquid purifying apparatus into a liquid to be purified in a state where an air inlet provided near one end of the fixed cylinder communicates with the atmosphere via an appropriate pipe. Immerse it in a vertical state with its one end facing up.
[0017]
In this state, when the motor is operated to rotate the delivery means in the communication chamber, the delivery means sends out the liquid in the communication chamber to the outside, so that the communication chamber and the fixed cylinder become negative pressure and the liquid suction port Liquid and air are introduced into the fixed cylinder from the air inlet and the air inlet, respectively.
[0018]
The liquid introduced into the fixed cylinder passes through a magnetic field formed by permanent magnets respectively disposed on the inner peripheral surface of the fixed cylinder and the outer peripheral surface of the rotary cylinder.
[0019]
When the liquid passes through the magnetic field in this way, for example, in the case of water, the water molecules are activated and the water molecule clusters are reduced. Therefore, oxygen in the air (bubbles) introduced into the fixed cylinder is easily dissolved between the clusters and the bubbles are easily divided.
[0020]
Furthermore, when the liquid as the conductive fluid passes through the magnetic field, an electric current is induced in the liquid, and electrolysis occurs. As a result, in the case of water, the clusters of water molecules are further reduced, so that oxygen in the bubbles is more easily dissolved between the clusters and the bubbles are more easily divided.
[0021]
Further, oxygen in the bubbles introduced into the fixed cylinder is activated by passing through a magnetic field, and is more easily dissolved between the clusters.
[0022]
From the above, it is considered that the bubbles introduced into the fixed cylinder enter the liquid introduced into the fixed cylinder in a subdivided state, and the oxygen in the bubbles dissolves in the liquid.
[0023]
The liquid in which the bubbles enter in a state of being subdivided and in which oxygen is dissolved is sent out to the outside of the liquid purification apparatus through the communication chamber by the sending means, and the outside liquid is purified.
[0024]
Next, the operation of the portion constituting the feature of claim 1 will be described.
[0025]
According to a first aspect of the present invention, a plurality of protrusions having a substantially trapezoidal cross section are formed on the inner peripheral surface of the fixed tube and the outer peripheral surface of the rotating tube, respectively, in the length direction of the fixed tube or the rotating tube. Since the gap between the stripes is a substantially inverted trapezoidal groove, and the permanent magnet is disposed in each of these grooves, a substantially cylinder bent in a zigzag shape by the inner peripheral surface of the fixed cylinder and the outer peripheral surface of the rotating cylinder A liquid passage is formed, and the width of the liquid passage changes drastically and narrowly as the inner rotary cylinder rotates. Accordingly, the state in which the liquid in the liquid passage becomes low speed and low pressure in the wide portion of the liquid passage and rapidly becomes high speed and high pressure in the narrow portion of the liquid passage is repeated vigorously. Further, when the inner rotating cylinder rotates, the outer fixed cylinder resonates (resonates). As a result, bubbles in the liquid passing through the liquid passage become extremely fine, and oxygen in the bubbles preferably dissolves in the liquid in the liquid passage.
[0026]
[Liquid purification device of claim 2]
In Claim 2, the depth (refer code | symbol d of FIG. 3) from the surface of the permanent magnet arrange | positioned in each groove | channel in the said rotation cylinder to the surface of the said protrusion is in each groove | channel in the said fixed cylinder. Since the depth from the surface of the disposed permanent magnet to the surface of the ridge (see symbol c in FIG. 3) is larger, the distance between the liquid passing through the outside in the liquid passage and the liquid passing through the inside A difference in speed occurs, and a twisting phenomenon of the liquid occurs, so that the liquid is sheared. As a result, bubbles in the liquid passing through the liquid passage become finer, and oxygen in the bubbles is preferably dissolved by the liquid in the liquid passage. In other respects, the invention of claim 2 has the same operation as that of the invention of claim 1.
[0027]
[Liquid purification apparatus according to claims 3 and 4]
The third and fourth aspects of the invention have the same operation as that of the first aspect of the invention.
[0028]
[Liquid purification apparatus of claim 5]
In Claim 5, since the stirring rod rotated by the said motor is arrange | positioned in the downstream of the liquid suction port and suction port in the said fixed cylinder, the liquid and air introduce | transduced in the fixed cylinder are said liquid channel | paths Before entering the air, the air is agitated by the agitation bar in advance, and the air is dispersed in the liquid as fine bubbles. Therefore, the bubbles are more preferably subdivided in the liquid passage.
[0029]
[Liquid purification apparatus of claim 6]
The stirring bar in claim 6 is provided with a permanent magnet, which acts in the same manner as the permanent magnet described in claim 1. Therefore, the bubbles in the liquid are dispersed in the liquid as finer bubbles before entering the liquid passage, and oxygen in the bubbles easily dissolves in the liquid.
[0030]
[Liquid purification apparatus of claim 7]
Since the permanent magnet according to claim 7 is mainly composed of neodymium or zirconium, unlike a ferrite magnet, for example, it is hard to break and has excellent durability.
[0031]
