Abstract

PURPOSE:To carry out filtration of a sufficiently large amount of water for a long duration by providing a hollow main body, a water supplying inlet, a hollow rotary body, a rotary body driving apparatus, a passing hole of the rotary body, a filter layer of the passing hole, and a water discharging outlet. CONSTITUTION:In a filtration apparatus 1, water to be filtered is supplied to a rotary body 5 through a supplying inlet 3, flows to outside from inside of the rotary body 5 while passing a filter layer 27, and is discharged through a passing hole 23 of the rotary body 5. When the water passes the filter layer 27, due to the rotation of the rotary body 5 by a turbine 29 which utilizes water flow from the supplying inlet 13, centrifugal force is applied to water to run forcedly toward outside. Consequently, since water passes the filter layer 27 uniformly while being filtered, possibility that impurities converge unevenly on a part and that choking occurs is lowered and even if choking occurs, a proper amount of water passes by the forcing centrifugal force and thus it is no need to clean or replace the filter layer 27 frequently.

It is supplied to the rotating body from the supply port and is discharged from the inside of the rotating body to the outside through the filter layer. Here, when the water passes through the filter layer, the water is forcibly applied with centrifugal force by the rotation of the rotating body toward the outside. For this reason, since water is uniformly dispersed in the filter layer and passes through, impurities are less likely to be concentrated and partially clogged. Moreover, even if it is slightly clogged, a moderate amount of water can pass through the filter layer because of the forced centrifugal force. Therefore, sufficient water can be filtered over a long period of time. As a result, there is no need to frequently clean or replace the filter layer, which is convenient and economical.

The filtering device 1 of this embodiment comprises a main body 3, a rotating body 5 and an activating layer 7. The main body 3 has a hollow cylindrical shape, and is provided with a circular supply port 13 for supplying tap water to the upper end 11 of the side surface 9, and is connected to a pipe 14 (for example, for connection with a tap or a tap). The medium material) and the sealing material are sealed and screwed together. Further, in the center of the bottom surface 15, a discharge port 1 for discharging filtered water.
7 is provided. Furthermore, in the inside 19 of the main body 3,
The rotating body 5 and the activation layer 7 are arranged.

The rotating body 5 is arranged in the upper center of the inside 19 of the main body 3 so as to be separated from the inner wall 3a of the main body 3, and has a hollow cylindrical shape having a bottom surface 20. The outer surface 21 is composed of an inert metal plate 25 such as stainless steel having a through hole 23, in which a filter layer 27 is arranged. Examples of the filter layer 27 include fibers, non-woven fabrics and polyesters having extremely small pores of several microns or less. Further, the rotating body 5 is provided with a turbine 29 that utilizes the water flow from the supply port 13. The turbine 29 is composed of a rotary blade 30 and a shaft 35, and the rotary blade 30 is rotated by the water flow from the supply port 13 hitting the rotary blade 30, and the shaft 35 is rotated accordingly.
The shaft 35 is inserted and fixed from the upper portion 31 of the rotating body 5 to the bottom surface 20, and the rotating body 5 rotates in conjunction with the shaft 35 of the turbine 29. Further, the rotating body 5 has a supply port 13
An upward trumpet-shaped guide plate 33 that guides the water supplied from the inside to the inside 32 of the rotating body 5 is provided from the inner wall 3 a of the main body 3 toward the inside 32 of the rotating body 5.

The activation layer 7 has a cylindrical shape and is provided below the rotating body 5 so as to be separated from the inner wall 3a on the side surface of the main body 3 and to have the bottom surface 34 connected to the discharge port 17. The activation layer 7 has a first layer 35 for activation made of far-infrared ceramic particles on the upper part and a second layer 37 made of glass fiber on the lower part, and is made of stainless steel or the like. It is covered with an active metal mesh 38.
In the first layer 35, a far infrared ceramic particle layer 35a having a relatively small particle size is arranged in the center, and a far infrared ceramic particle layer 35b having a relatively large particle size is formed so as to surround the far infrared ceramic particle layer 35a. It is arranged in the shape of. Here, the filler for activation and filtration of the activation layer 7 is not limited to the far-infrared ceramic particles or the glass fiber, and a commonly used filler, for example, for deodorizing scaly or mold. Granular activated carbon, foamed resin, sintered resin and the like can be mentioned, and these can be appropriately selected according to the application and purpose and can be used in combination in an appropriate positional relationship. Also,
In order to activate water, an electrode that electrolyzes water or a magnet that magnetically decomposes water may be provided. A boundary line 41 existing on the outer circumference 40 of the first layer and the second layer is provided with a trumpet-shaped separating plate 43 that is connected to the inner wall 3a of the main body 3 and faces upward, and allows water to pass through the first layer. Without preventing it from flowing into the second layer.

According to the filtering device 1 constructed as described above, as shown by the arrow in FIG.
The water supplied to No. 3 is supplied into the rotating body 5 while applying water pressure to the turbine 29 to rotate the rotating body 5. The water supplied into the rotating body 5 is forcibly subjected to centrifugal force due to the rotation of the rotating body 5 and is discharged to the inside 19 of the main body 3 outside the rotating body 5. Here, the water is the outer surface 2 of the rotating body 5.
When passing through the passage hole 23 provided in No. 1, it passes through the filter layer 27 arranged therein. At this time, the water removes impurities such as iron rust, dust, minerals, and calculus, but it is said that it has been clogged somewhat because it has been used for a long period of time or because the water is significantly contaminated (including hard water). Also, since the forced centrifugal force is applied to the outside by the rotation of the rotating body 5, the water can pass with an appropriate water flow. Moreover, since the water is uniformly dispersed and discharged by the rotation of the rotating body 5, impurities are not concentrated in a part and clogging is less likely to occur.

The water removed from the impurities by the rotating body 5 and discharged to the inside 19 of the main body 3 outside the rotating body 5 flows into the first layer 35 of the activation layer 7 by the separating plate 43, and the water is discharged. Activation of the molecule takes place. Here, since impurities have already been removed from the water by the rotating body 5, the activation layer 7 is not contaminated by impurities and clogging does not occur.
First, water is a far-infrared ceramic particle layer 35 having a large particle size.
b into the far-infrared ceramic particle layer 35a having a small particle size. Here, since the far-infrared ceramic particle layer 35b having a large particle size has a large particle size, the gap is large and the water flow is not obstructed. Further, since the far-infrared ceramic particle layer 35a having a small particle size has a small particle size, the contact surface area during the inflow of water becomes large and is sufficiently activated. Furthermore, since the far-infrared ceramic particle layer 35b having a large particle size has a U-shape and a large inflow surface area, water easily flows in.

Further, the water that has passed through the first layer is activated layer 7
Of the small particles from the first layer 35 and the final filtration. Here, since the inflow surface area of the first layer 35 is large, the flow resistance is small, and a large amount of water flows in from the first layer 35, that is, because the water pressure is high, the water smoothly flows through the second layer. pass. Then, after the activation and filtration by the activation layer 7 are performed, the water is discharged from the discharge port 17.

According to the above-described embodiment, the filter layer 27 is rotated, and the water is subjected to a forced centrifugal force to cause the filter layer 2 to rotate.
Since it was configured to pass through 7, it was possible to obtain an appropriate water flow even if some clogging occurred. Moreover, the rotating body 5
Since the water is uniformly dispersed in the filter layer 27 and discharged by the rotation of (1), impurities are not concentrated in a part and clogging is less likely to occur. Therefore, it was possible to obtain a good water flow for a long period of 2-3 times as compared with the case where a columnar filter layer is used as usual. Further, according to the filtering device 1 of the present embodiment, since the turbine 29 that uses the water flow supplied from the supply port 13 is used as the one that applies the rotational driving force to the rotating body 5, no special power is required, There is no energy consumption.

After long-term use, the rotating body 5
Hang it in the sun to dry it and tap it well to filter layer 27
It can be reused by removing impurities adhering to the inside. Also, it may be replaced anew. The activation layer 7 is replaced in a certain period depending on its capacity, the quality of water used, and the like.

The filtering device 1 as in the above embodiment is also useful for domestic tap water or well water, but since it has a large filtering capacity, it can be used for commercial purposes such as restaurants and food manufacturing industries. it can. Although the rotating body 5 is rotated by the turbine 29 in this embodiment, an electric power or the like may be used as an energy source in order to increase the driving force.

The embodiment of the present invention has been described above.
The present invention is not limited to these examples, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.
