Description

The present invention relates to a disperser for aeration used for water purification, biological growth, etc. in general water areas such as sea, lakes, rivers, brackish water areas, or live fish tanks and ginger of aquaculture.

As the aeration disperser, a cylindrical disperser formed of a porous material such as a porous film or porous ceramic so as to have a space inside is generally used.

Pressurized air and oxygen are fed into the space formed inside the disperser, and the pressurized air and oxygen permeate through countless pores formed in the porous material. By being released in the form of bubbles, aeration is performed in the enforcement water area.

Pressurized gas such as air or oxygen permeates through the pores of porous membranes, porous ceramics, etc. and is released to the water area. When the pressure is reduced, water enters the disperser, and when the gas pressure is increased, bubbles that cannot be expressed as fine bubbles are released into the water area, creating fine bubbles that can stay in water for a long time. It has become difficult to do.

For aeration dispersers used for water purification, biological growth, etc. in live fish tanks, ginger etc. in aquaculture farms, it is an issue to be able to create fine bubbles that are easily dissolved in water. Yes. This invention is providing the disperser for aeration which creates the fine bubble which is easy to melt | dissolve in water by adding a new technique to the surface of the conventional disperser.

The present invention creates a fine bubble that is easy to dissolve in water by adding a new technology to the surface of a disperser that is widely known for aeration. By covering the surface of a disperser formed of a porous material such as ceramics so as to be wound with thread-like fibers, fine bubbles that easily dissolve in water are created in the water.

The present invention creates a fine bubble that is easy to dissolve in water by adding a new technology to the surface of a disperser that is widely known for aeration. By covering the surface of a disperser formed of a porous material such as ceramics so as to be wrapped with hydrophilic filamentous fibers, a bubble-breaking effect is expressed in the gas permeable part, and fine bubbles that are easily dissolved in water are formed. It becomes easy to create underwater.

As the aeration disperser, a cylindrical disperser formed of a porous material such as a porous film or a porous ceramic so as to have a space inside is widely known. According to the first aspect of the present invention, the surface of the cylindrical disperser is covered with a thread fiber made of silk, cotton, hemp or the like so as to be wound around without any gaps, thereby finely generating bubbles generated from the disperser. It is characterized by being released into water.

The filamentous fiber employed in this device was exemplified because natural fibers such as silk, cotton, and linen have hydrophilicity, but polyvinyl alcohol (PVA) has hydrophilicity and excellent chemical resistance. Since it is not biodegradable as a characteristic of chemical fiber, it can be said that the material is suitable for use in the present invention.

Regardless of natural fiber or synthetic fiber, it can be used if it has hydrophilicity, and even a material that does not have hydrophilicity can be adopted in the present invention by making it hydrophilic. it can.

The invention described in claim 2 covers the surface of a widely known disperser widely used for aeration with a non-woven fabric having hydrophilicity, and winds the filamentous fiber according to claim 1 around the outer periphery of the disperser. It is a dispersion device for aeration characterized by maintaining the coating form of the dispersion device with a coating material, and bubbles generated from the dispersion device are attracted and refined in a hydrophilic non-woven fabric covering the surface of the dispersion device. Fine bubbles are released into the water.

The present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of the device according to claim 1, wherein the surface of the cylindrical disperser is covered so as to be wound with a fiber-like fiber made of silk, cotton, hemp or the like without gaps. is there.

As the aeration disperser 2, a cylindrical disperser formed by a porous material 4 such as a porous film or porous ceramics so as to have a space 6 therein is widely known. In the invention described in claim 1, the surface 8 of the cylindrical disperser is covered with a filamentous fiber 10 made of silk, cotton, hemp or the like so as to be wound around without any gap, thereby generating bubbles generated from the disperser. It is characterized in that it is attracted and is refined and released into water.

FIG. 2 is a device explanatory diagram according to claim 2. The surface of the disperser 2, which is widely known for aeration, is coated with a hydrophilic woven fabric and nonwoven fabric 12, and the like. And a disperser for aeration characterized by maintaining a covering form of the disperser with a covering material such as the nonwoven fabric 12, and bubbles generated from the disperser are hydrophilic woven fabric and nonwoven fabric covering the surface of the disperser 12 is refined and fine bubbles are released into the water.

As the woven fabric and non-woven fabric used in the present invention, cotton woven fabric is also suitable, but composite non-woven fabric of pulp and synthetic fiber is also suitable. Polyvinyl alcohol (PVA), polyethylene, Polypropylene, polyamide, polyester, acrylic, vinylon, etc. are used. Moreover, as long as it has corrosion resistance in addition to hydrophilicity and breathability, it may be a composite nonwoven fabric or a composite woven fabric with glass fiber, metal fiber, etc., and the material, composition, and weaving method are particularly limited. It is not something.

In porous materials such as porous membranes and porous ceramics, polytetrafluoroethylene (PTFE) porous membranes, breathable films formed by forming crazes on polymer resin films, etc. are adopted as porous membranes. The
