Filter and laser printing manufacturing method and application thereof

Abstract

The invention discloses a filter and a laser printing manufacturing method and application thereof. By the adoption of a laser printing method, the structure of the filter is not limited by technological conditions any more, filters of any structures can be manufactured, and filters with complicated curved surfaces and complicated pores can be directly manufactured. Because the laser printing method is used for manufacturing, the number of filtering layers of the filter will not be limited, and filtering pores in the filtering layers can be designed to be gradient holes; polluted fuel is in contact with the inner filtering layer firstly; large pollutants are intercepted by large filtering pores, and small pollutants are intercepted by small filtering pores; the intercepted pollutants slide to the lower end along the filtering pores, so that layered filtering is achieved; in this way, the filtering effect is improved, and the filtering pores are prevented from being blocked; and the service life of a filtering element is greatly prolonged, and the filter manufactured according to the laser printing manufacturing method can be designed at will according to actual requirements to meet use requirements.

Description

technical field [0001] The invention relates to the technical field of filter manufacturing, in particular to a filter and its laser printing preparation method and application. Background technique [0002] The filter is an essential accessory in the engine filtration system, which is used to filter the metal debris generated during the operation of the engine and various solids formed by oxidation at high temperature, so as to reduce the wear rate of the engine and prolong the service life of the engine. The traditional fuel filter uses filter cotton or filter paper to filter fuel, which has low filter efficiency and has a great impact on the power of the engine. Moreover, after a long period of use, multi-layer filter cotton or filter paper will shed slender fibers, causing grease pollution. When the pollutants are close to the filter cotton or filter paper, most of them will adhere to it, resulting in a longer service life of the filter element. reduce. The traditional...
