Problems solved by technology

[0002] At present, most of the lubricating oil filters for internal combustion engines in my country use corrugated paper and metal mesh. In use, due to the low structural strength of the corrugated paper filter, it is prone to tearing and falling apart, which affects the filtering effect and has a short service life; Due to the limited mesh size of the mesh filter element, the filtering effect is not ideal
Although ZL90101748 discloses a full-flow deep fiber purification filter element, the original resistance of the filter element is relatively large due to the specifications of wood chips and cotton used in the filter element and the unreasonable ratio of wood chips and cotton. Increased uncertainties in lubricating oils for internal combustion engines affect the use of lubricating oils

Embodiment

[0014] Put the wood residue with a specification of 49-100 mesh and the cotton with a length of 15-40 mm in a stirring tank filled with sodium bicarbonate solution, the sodium bicarbonate solution is a concentration of 2%-5%, soak and stir evenly, and then The stirring tank is heated to degrease the wood residue and cotton. The temperature of soaking and degreasing is 50-70°C, and the time of soaking and degreasing is 5-10 hours. Put the degreased wood residue and cotton into the compression mold, and use a press Squeeze out the impurities and sodium bicarbonate solution in the wood residue and cotton, remove the impurities and sodium bicarbonate in the wood residue and cotton, rinse the wood residue and cotton in clean water, put them into a compression mold and use a press to remove them The sodium bicarbonate solution in it, until the wood residue and cotton are thoroughly cleaned, the wood residue and cotton after degreasing, compression and rinsing are put into the filter ...

Abstract

The precision filter element for internal combustion engine lubricating oil is produced with 49-100 mesh wood residue and 15-40 mm length cotton in the ratio of 100 to 5-40, and through mixing, defatting, rinsing, compression to form and stoving at negative pressure. It has simple production process, low cost, high filtering effect and small initial resistance, and is suitable especially for filtering lubricant oil.

Description

Technical field: [0001] The invention relates to a filter material, in particular to a precision filter element for lubricating oil of an internal combustion engine. Background technique: [0002] At present, most of the lubricating oil filters for internal combustion engines in my country use corrugated paper and metal mesh. In use, due to the low structural strength of the corrugated paper filter, it is prone to tearing and falling apart, which affects the filtering effect and has a short service life; Due to the limited mesh size of the mesh filter element, the filtering effect is not ideal. Although ZL90101748 discloses a full-flow deep fiber purification filter element, the original resistance of the filter element is relatively large due to the specifications of wood chips and cotton used in the filter element and the unreasonable ratio of wood chips and cotton. The uncertain factors of internal combustion engine lubricating oil increase, which affects the use of lubri...
