Embodiment 1

[0026] Figure 5 This is the first embodiment of the oil ultrafiltration filter of the present invention. The top of the filter cylinder 3 is provided with an oil inlet 4, and the cylindrical filter element 2 is installed in the cylinder 3. The filter element 2 of this embodiment is composed of Several layers of filter paper 1 are stacked. The filter paper 1 has a circular ring shape. The through hole in the middle part is stacked to form a cylindrical central hole 6. The central hole 6 communicates with the oil outlet 5 at the bottom of the cylinder 3. When working, the dirty oil 21 enters from the top oil inlet 4 and is distributed to the periphery of the cylinder 3 through the oil distribution channel. Under a certain pressure, the dirty oil 21 changes from a vertical flow state to a horizontal flow state, and passes through a layer of filter paper. Gap channels between slices. Using the above filtering principle, the impurities 22 in the dirty engine oil 21 are trapped in t...

Embodiment 2

[0028] Image 6 This is the second embodiment of the oil ultrafiltration filter of the present invention. The top of the filter cylinder 3 is provided with an oil outlet 5, the center of the cylinder 3 is provided with an oil inlet pipe 7, and the oil inlet pipe 7 is at a certain There are several oil distribution holes 8 on the height. The cylindrical filter element 2 is installed in the cylinder 3 and fixed on the central oil inlet pipe 7. In this embodiment, the filter element 2 is a disc-shaped filter paper 1 roll, such as Image 6 As shown, the filter element 2 is composed of six disc paper rolls, divided into three groups, and the outer circumference of two adjacent paper rolls in each group is provided with a sleeve 9 to isolate the external oil outlet channel; each group An oil inlet gap 11 is provided between the two adjacent paper reels, and the position of the oil inlet gap 11 is set exactly at the height of the oil distribution hole 8 on the oil inlet pipe 7. An o...

Abstract

The invention discloses an ultrafiltration filter for engine oil. The ultrafiltration filter for engine oil comprises a barrel body, an oil inlet port, an oil outlet port and a filter element, wherein the filter element is composed of a plurality of layers of filter paper; a flowing direction of the engine oil is parallel to an arrangement direction of the filter paper; the dirt engine oil flows to pass through gaps among the layer sheets of the filter paper; and the filter paper is microscopically provided with convex-concave parts, and impurities such as colloidal particles of sludge collide with the filter paper, and are adhered to and retained on the concave parts of the filter paper during a flowing direction of the engine oil, thus filtration for the engine oil is realized. The ultrafiltration filter for engine oil, which is disclosed by the invention, breaks through a traditional filter method of filtering vertical runoff through meshes, the engine oil passes through the filter element composed of the plurality of layers of filter paper in a manner of parallel runoff, and the colloidal particles of the sludge collide with a filter screen, and are adhered to the filter paper to be removed by virtue of the zigzag Brownian motion of the particles of the sludge. The ultrafiltration filter for engine oil, which is disclosed by the invention, has a fast dirt filter speed, effectively removes the impurities such as the sludge accumulated in the engine oil, and is capable of removing tiny particles of the sludge, thus achieving extremely high filter quality.

Description

Technical field [0001] The invention relates to the field of petrochemical industry, in particular to an oil ultrafiltration filter, filter element and filter paper. Background technique [0002] Oil contamination can cause many kinds of engine failures: for example, exhaust valve seat surface damage, increased wear of cylinder liner piston rings, deterioration of oil circulation due to blockage and corrosion of oil passages and inducing failures, the back of engine bearings due to sludge accumulation and adhesion. The bearing is in contact on one side, etc. Therefore, ensuring the cleanliness of the engine oil system and achieving high-efficiency filtration of sludge generated in the oil is of great significance to improving the reliability, durability and economy of the engine. Existing oil filters such as figure 1 , figure 2 As shown, the used dirty engine oil 21 containing a large amount of impurities 22 passes through the mesh gap of the filter screen 10. The impurities 22...
