- An automobile engine includes a large number of parts and an oil filter as an accessory device.
- Engine oil becomes dirty with wear powder, impurities, carbon, etc. when used.
- dirty oil from the engine passes through the filter element, and dust and carbon are removed and filtered before returning to the engine.
- the oil filter prevents wear and seizure of each part of the engine and contributes to ensuring the reliability of the engine.
- the outer case of the oil filter is made of metal such as aluminum-yuum or iron, and the filter element is made of paper at the collar portion and the bundling portions at both ends are made of metal. In addition, it consists of rubber packing and used oil.
- Most of the current oil filters have an integral structure in which a filter element is installed and wrapped in an outer cylinder case. These are always changed during oil changes and vehicle inspections. These numbers are consumed 50 million domestically, and most of them are landfilled 2.5 million tons every year as industrial waste.
- old oil filters that have been replaced have been disassembled as much as possible rather than being discarded as they are in an assembled state, and these parts are separated according to the material type. Yes.
- one end of the outer cylinder case is cut into a ring with a cylindrical blade and the lid is removed. Then, drain the oil from the outer case and remove the filter element. Next, the flanges at both ends where the filter elements are bound are cut with a press blade, and separated into paper and metal. In this way, the oil filter is separated into used oil, outer casing, metal at both ends of the filter element, filter element paper, knocker rubber, and the like.
- FIG. 1 shows the lid 1

- the conventional oil filter has the following problems.
- the first problem of the conventional oil filter is that the outer cylinder case has an integral structure, so that the outer circumference needs to be cut into round pieces with a cylindrical blade and cannot be regenerated.
- oil filters have the ability to be separated into oil, metal, rubber, and paper by material. This takes time and is sufficient to meet the need for cost reduction for recycling.
- the second problem is a structure in which the lid portion of the outer cylinder case and the main body portion are screwed together, and this thread is a small-pitch, multi-thread screw with mechanical force applied. For this reason, it takes time to unscrew the lid and it is troublesome to disassemble.
- the oil filter of the present invention is made to solve such problems of the conventional oil filter, and it is necessary to form a forged screw with a large pitch at the threaded portion. It has been modified so that it can be screwed back and disassembled instantly.
- the structure is such that the screw can be prevented from loosening by providing a protrusion on the screw part of the lid.
- the outer cylinder case can be used as it is without being discarded, the number of discarded parts is reduced as much as possible, and only the oil, rubber packing, and paper filter elements need to be replaced. Oil filter that contributes to reduction Means for solving the problem
