JPH11262610A - Element for air filter - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable long-term use of an element in the air filter of an internal combustion engine by forming the element of materials having durability and corrosion resistance so that it can be washed with a liq. at the time of regeneration. SOLUTION: The element has an inner tube 1 comprising a punched metal and a top plate 2 comprising a steel sheet. A stainless mesh 3 having minute meshes is disposed at the outside of the inner tube 1 so that fine dust in air can be filtered off. A stainless mesh 4 having minute meshes and an increased surface area due to its bellows shape is disposed at the outside of the mesh 3 so that fine dust in air can further be filtered off. An outer tube 5 comprising a punched metal is disposed at the outside of the mesh 4 to impart strength to the entire element. A partition plate 6 for partition into a filtration part and a dust accumulation part 8 is disposed at one end of the element and dust falling from many holes pierced in the partition plate 6 is accumulated in the accumulation part 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an element used for an air filter of an internal combustion engine.

[0002]

2. Description of the Related Art Conventionally, various attempts have been made to improve the performance of an element used for an air filter of an internal combustion engine.

[0003] However, in most cases, the filtration of combustion air is performed by filter paper, and the filter paper is clogged in the course of use and the pressure loss is increased.
Not enough air goes into the combustion chamber, causing incomplete combustion.

[0004] And because it is natural to disposable,
At present, it is difficult to use incinerators due to the dioxin problem.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air filter element which remarkably improves the durability of the air filter element, is not disposable, and is easy to clean during regeneration. I have.

[0006]

In order to achieve the above object, according to the present invention, filtration of combustion air is performed by using a mesh or screen of a corrosion-resistant alloy in combination without using filter paper. , The whole element is durable,
It was made of a material having corrosion resistance.

In the present invention, the captured dust is accumulated in the lower portion of the element to minimize clogging of the filter, and the entire element can be washed by liquid washing during regeneration. Configured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments. In FIG. 1, reference numeral 1 denotes an inner cylinder, which is made of the same punched metal as the conventional product, and 2 is a top plate, which is made of the same steel plate as the conventional product. Reference numeral 3 denotes a stainless steel mesh having a fine mesh, which filters fine dust in the air.

Reference numeral 4 denotes a stainless steel mesh having a fine mesh, which is folded in a bellows shape to increase the surface area, and filters fine dust in the air. Reference numeral 5 denotes an outer cylinder, which is made of the same punch metal as that of the conventional product, and has a function of preventing intrusion of dust and the like larger than the punch holes and a function of giving strength to the entire element.

Reference numeral 6 denotes a partition plate for partitioning the filtration unit and the dust accumulation unit, and a large number of holes are formed in the steel plate. Reference numerals 7, 9, 10 and 11 are lower caps of the element. The upper filtration part is inserted between 7 and 10 and stopped by the stopper of 11. 8
Numeral denotes a dust accumulation portion provided in the lower cap, and accumulates dust that has fallen from a hole formed in the partition plate 6.

The stopper 11 also has a function of preventing the dust in the dust accumulation section 8 from flowing backward and entering inside the filtration section.

[0012]

Since the present invention is configured as described above, it has the following effects.

Since the entire air element is made of a material having durability and corrosion resistance, it can be used for a long period of time and does not have to be disposable as in the prior art, thereby solving the problem of waste disposal.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Further, the present invention is a filtration method using a metal mesh in a complex manner, and the dust caught by each mesh is automatically dropped by the vibration of a vehicle and an engine and is accumulated in a dust accumulation part. It has the advantage of being less likely to be clogged as compared to filter paper, and has the effect of reducing incomplete combustion due to insufficient air.

At the time of maintenance, since the liquid can be washed by removing the lower cap, work in a poor working environment such as conventional cleaning and regeneration of the element by compressed air is eliminated. .
