  Hereinafter, an embodiment of a method for regenerating a cylindrical air filter cleaner for an internal combustion engine according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a cross-sectional view of a cylindrical air filtration cleaner A obtained by applying the method for regenerating a cylindrical air filtration cleaner according to the present invention.
The cylindrical air filter cleaner A is installed in an intake air flow path as an intake system of an internal combustion engine. Reference numeral 23 denotes an innermost cylindrical body as a frame on the internal combustion engine side, which is composed of expanded metal, punching metal, or the like.
This expanded metal is formed of a material such as iron, stainless steel, or aluminum steel. For example, the original mesh is rolled to form a thin plate on the same plane, and various surface treatments such as galvanizing or coating are performed. Then, the expanded metal having a thin plate shape is formed into the innermost cylindrical body 23. Further, the innermost cylindrical body 23 can be formed by, for example, using a punching metal and drilling holes patterned in a thin plate shape.
A cylindrical frame having the same configuration as that of the inner cylindrical body 23 may be provided on the outermost side.

  Reference numeral 24 denotes a first fiber material, which is wound around the outer or outer surface of the innermost cylindrical body 23 and formed into a cylindrical shape.

25 is a carbon sheet material, wound around the outer surface of the first fibrous material 24, the material is carbon cellulose material.

The carbon sheet material 25 is composed of a single layer or a plurality of layers, for example, a three-layer cylindrical body.

26 is a second fiber material made of the same material as the first fiber material 24, is wound around the outer surface of the carbon sheet material 25 to form a cylindrical shape, and has a single layer or a plurality of layers. Forming. FIG. 1 shows a second fiber material 26 having four layers. A third fiber material 27 having the same material and shape as the first and second fiber materials 24 and 26 is wound on the outermost side. The third fiber material 27 is a single or multilayer structure on the outside air introduction side of the second fiber material 26, and has a function as a demountable fiber material that is detachably covered and configured.

  The first and second fiber materials 24 and 26 are metal that is erected and fixed in advance in the winding direction with a hot bond or an adhesive or the like at the peripheral portion on the opposite surface side of the upper and lower thin flat ring or ridge. The first and second flat bars 28a, 28b made of or made of hard plastic are wound around the inside. The third fiber material 27 is substantially perpendicular to the winding direction and is formed of a third flat plate bar 28c that is erected and fixed with a hot bond or an adhesive or the like at the peripheral portion on the opposite surface side of the upper and lower ridges. Both side surfaces are bonded and fixed with male and female surface fasteners 27a and 27b. The first to third flat bars 28a, 28b, and 28c are separated from each other at an angle of, for example, approximately 120 ° from the center of the cylindrical air filter cleaner A as shown in FIG. Yes.

  As shown in FIG. 2, the third fiber material 27 as the removable fiber material is formed in a flat plate shape made of a substantially rectangular body, and male and female surface fasteners 27a and 27b are fixed to both ends thereof. After being wound, it is fixed to both side surfaces of the third flat plate bar 28c with the hook-and-loop fasteners 27a and 27b.

Thus, when the intake air is sent to the intake air flow path as the intake pipe at a speed of 3 m / second, for example, the intake air P1 shown in FIG. 1 passes through the third and second fiber materials 27 and 26. Then, the carbon sheet material 25 and the first fiber material 24 are passed through.

Next, the assembly procedure and method of the cylindrical air filtration cleaner A will be described.
In a used air filtration cleaner 1A as shown in FIG. 3 (a), first, the outer cylinder 2A made of expanded metal or punching metal is peeled off as shown in FIG. 3 (b). Then, the filter 3A made of filter paper is removed (see FIG. 4A).

Next, as shown in FIG. 4 (b), the peripheral portions 29 a and 29 b of the mutually opposing surfaces of the flanges 29 and 29 provided on the upper and lower sides of the innermost cylindrical body 23 are made of the metal or hard plastic, for example. The first, second, and third flat bars 28a, 28b, and 28c are suspended and are erected and fixed by hot bonds, adhesives, or the like. At this time, the first and second flat bars 28a and 28b are parallel to the surface of the innermost cylindrical body 23 and are arranged in the tangential direction thereof. Further, the third flat plate bar 28 c is arranged in a direction perpendicular to the surface of the innermost inner cylindrical body 23. Thus, a space S is formed between the surface of the innermost inner cylinder 23 and the surfaces of the first to third flat bars 28a to 28c, and the first fiber material 24 and the carbon sheet shown in FIG. The material 25 and the second fiber material 26 composed of a single layer or multiple layers are wound.

Further, as shown in FIG. 5 (a), the first fiber material 24 is wound around the outer surface of the innermost cylindrical body 23, both ends thereof are fixed with an adhesive or the like, and the first fiber material 24 is The inner cylinder 23 is fixed. The function of the first fiber material 24 is that when the intake air flows through the cylindrical air filter cleaner A, for example, carbon fine particles contained in the carbon sheet material 25 are mixed into the internal combustion engine by the intake air. To prevent. And the said 1st thru | or 3rd fiber materials 24, 26, and 27 have a function as filtration.

Then, the outer periphery surface of the first fibrous material 24 as shown in FIG. 5 (b), a carbon sheet material 25 is wound single or multiple and attach the ends in hot bonding or adhesive .

Further, as shown in FIG. 6A, the second fiber material 26 is wound around the outer surface of the carbon sheet material 25 one or more times. At this time, it passes through the inside of the first to third flat plate bars 28a, 28b, and 28c, which are erected and fixed to the peripheral edge portions 29a and 29b on the opposing surfaces of the upper and lower flanges 29 and 29, that is, the space S. Then, the ends of the second fiber material 26 are fixed with hot bonds or adhesives. Note that a male or female hook-and-loop fastener may be affixed to the end of the second fiber material 26 and fixed by bonding them.

Then, as shown in FIG. 6B, the third fiber material 27 is wound around the outer surface of the second fiber material 26 one or more times. At this time, as shown in FIG. 1, the third fiber material 27 covers the first and second flat bars 28a and 28b, and male and female hook-and-loop fasteners 27a and 27b are fixed to both ends thereof. The male / female surface fasteners 27a and 27b are fixed to both side surfaces of the third flat bar 28c.

The used cylindrical air filter cleaner 1A can be regenerated by the assembly procedure described above. In this way, the innermost cylindrical body 23 made of expanded metal or the like and the upper and lower ridges 29, 29 can be used effectively, and assembly can be speeded up and rationalized.
In addition, when a vehicle equipped with the regenerated cylindrical air filter cleaner A is inspected after traveling thousands of kilometers or tens of thousands of kilometers, etc., due to dust or the like contained in the air sucked into the internal combustion engine, When the removable fiber material, that is, the third fiber material 27 is dirty, the third fiber material 27 attached to the cylindrical air filtration cleaner A with male and female surface fasteners 27a and 27b is removed, It can be used over and over again by rinsing with a neutral detergent, etc., and then rinsing and drying.
