The pre-filtered oil is then filtered through filter paper, preventing sludge and other impurities from clogging the filter paper and ensuring continuous and efficient filtration.

Description

Technical Field

[0001] This utility model specifically relates to an oil filter with a separator plate, belonging to the field of filter technology. Background Technology

[0002] The oil filter is a key component of the automotive lubrication system. When the engine is running, the oil carries metal shavings, impurities, etc. The filter can filter out these contaminants, keep the oil clean, reduce component wear, extend engine life, and ensure stable lubrication and heat dissipation functions. It is of great significance to maintaining the engine in good working condition.

[0003] After the filter has been used for a long time, large iron filings, impurities, and sludge carried out by the lubricating oil from the engine will be adsorbed on the surface of the filter paper. When the adsorption of impurities reaches a certain level, the filter pores on the surface of the filter paper will be blocked, thus affecting the filtration effect. At this time, the internal pressure of the filter element increases, and the bypass valve can only be opened to allow unfiltered engine oil to enter the engine, resulting in engine wear and affecting the engine's service life.

[0004] To address the aforementioned issues, this application proposes an oil filter with a separator plate. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an oil filter with a separator plate. By designing a separator plate, filter holes, and a sedimentation chamber, larger impurities and iron filings in the oil are separated and precipitated into the sedimentation chamber at the bottom of the filter element through the filter holes on the separator plate. This prevents impurities from entering the filter element, even when the bypass valve is open, thus avoiding clogging of the filter paper by sludge and other impurities and solving the problems mentioned in the background art.

[0006] An oil filter with a separator plate includes a filter body, an outer shell on the outside of the filter body, a filter element inside the outer shell, a separator plate on the outside of the filter element, and multiple sets of filter holes on the surface of the separator plate for filtering impurities and iron filings in the oil. A set of fixing rings is installed on the upper and lower sides of the filter element. The separator plate has several sets of rings that are equidistantly arranged around the outside of the filter paper and connected to the upper and lower sets of fixing rings. A sedimentation chamber is provided between the outer shell and the fixing rings at the bottom.

[0007] In a preferred embodiment, the filter element includes an inner metal mesh installed inside the filter body and filter paper installed outside the inner metal mesh.

[0008] In a preferred embodiment, the separating plate is designed to be inclined along the circumferential surface of the fixing ring and forms an acute angle with the circumferential surface of the fixing ring, which is used to guide impurities and prevent impurities from accumulating on the surface of the separating plate.

[0009] In a preferred embodiment, the separation plate is made of nylon material.

[0010] In a preferred embodiment, an outer sealing ring is installed on the top of the filter body.

[0011] In a preferred embodiment, an anti-backflow valve is installed at the upper part of the filter body, and a bypass valve is installed at the lower part of the filter body.

[0012] In a preferred embodiment, a connecting plate is installed above the anti-backflow valve, and the connecting plate is connected to the outer casing.

[0013] In a preferred embodiment, the surface of the metal inner mesh has multiple sets of mesh holes, and the upper end of the metal inner mesh is connected to the anti-backflow valve.

[0014] Beneficial effects:

[0015] By designing a separation plate, filter holes, and sedimentation chamber, when engine oil containing impurities enters the filter, it first passes through the filter holes on the separation plate to separate large impurities and iron filings, which then settle into the sedimentation chamber at the bottom of the filter element. This prevents impurities from entering the filter element, even if the bypass valve is open. The engine oil that has undergone preliminary filtration then passes through the filter paper to prevent larger impurities such as sludge from clogging the filter paper. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, an oil filter with a separator plate includes a filter body, an outer shell 6 on the outside of the filter body, a filter element inside the outer shell 6, and a separator plate 4 on the outside of the filter element. The surface of the separator plate 4 has multiple sets of filter holes 10 for filtering impurities and iron filings in the oil. A set of fixing rings 5 ​​are installed on the upper and lower sides of the filter element. The separator plate 4 has several sets of rings that are equidistantly arranged around the outside of the filter paper 7 and connected to the upper and lower sets of fixing rings 5. A sedimentation chamber is provided between the outer shell 6 and the fixing rings 5 ​​at the bottom. The separator plate 4 performs preliminary filtration of larger impurities and iron filings in the oil through the filter holes 10 on its surface. The sedimentation chamber is used to collect the impurities and iron filings filtered out by the separator plate 4 to prevent them from mixing back into the oil.

[0023] Please see Figures 1-3 As shown, the filter element includes an inner metal mesh 8 installed inside the filter body and a filter paper 7 installed outside the inner metal mesh 8. The inner metal mesh 8 supports the filter paper 7 and enhances the structural strength of the filter element. The filter paper 7 is used to further filter fine impurities in the oil and improve the filtration accuracy.

[0024] Please see Figures 1-2 As shown, the separation plate 4 is designed to be inclined along the circumference of the fixing ring 5 and forms an acute angle with the circumference of the fixing ring 5. This is used to guide impurities and prevent impurities from accumulating on the surface of the separation plate 4. The inclined design of the acute angle can guide impurities to flow along the plate surface in a specific direction by means of the inclined angle of the separation plate 4 itself, avoiding impurities from accumulating locally and improving the efficiency of impurity separation and discharge. The inclined structure makes it easier for impurities to detach from the surface of the separation plate 4 under the action of gravity or fluid force, reducing the probability of impurities adhering to the plate due to long-term retention.

[0025] Please see Figures 1-2 As shown, the separator plate 4 is made of nylon material. Nylon material has good wear resistance, oil resistance and certain strength, making it suitable as the material for separator plate 4. It can work stably in the oil environment for a long time and ensure the filtration effect.

[0026] Please see Figures 1-2 As shown, an outer sealing ring 1 is installed on the top of the filter body. The outer sealing ring 1 is used to enhance the sealing between the filter body and the external connecting parts to prevent oil leakage at the connection.

[0027] Please see Figures 1-2 As shown, an anti-backflow valve 3 is installed at the top inside the filter body, and a bypass valve 11 is installed at the bottom inside the filter body. The anti-backflow valve 3 can prevent the oil in the filter from flowing back when the engine stops working, ensuring that there is enough oil in the oil circuit when the engine starts next time. The bypass valve 11 opens when the filter element is blocked, causing the oil flow to be obstructed, so that the oil can bypass the filter element and enter the subsequent oil circuit, avoiding damage to the engine due to lack of oil.

[0028] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, a connecting plate 2 is installed above the anti-backflow valve 3, and the connecting plate 2 is connected to the outer casing 6.

[0029] Please see Figures 2-3 As shown, the surface of the metal inner mesh 8 has multiple sets of mesh holes 9. The upper end of the metal inner mesh 8 is connected to the anti-backflow valve 3. The mesh holes 9 provide a flow channel for the filtered oil, allowing the oil to enter the interior of the metal inner mesh 8. The metal inner mesh 8 is connected to the anti-backflow valve 3, which facilitates the filtered oil to enter the subsequent oil circuit through the anti-backflow valve 3.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] When the filter is working, the engine oil enters the housing 6 and first comes into contact with the separator plate 4 surrounding the outside of the filter element. The separator plate 4 is made of nylon material and is distributed in a ring at equal intervals and is connected to the upper and lower sides of the filter element by the fixing ring 5. The multiple sets of filter holes 10 on its surface will first filter the large particles and iron filings in the engine oil. The separated large particles and iron filings will settle into the sedimentation chamber at the bottom inside the housing 6. The engine oil after preliminary filtration continues to flow to the filter element, which is composed of a metal inner mesh 8 and a filter paper 7 on its outer side. The filter paper 7 further filters the fine impurities in the engine oil. The filtered engine oil enters its interior through the mesh holes 9 of the metal inner mesh 8 and then flows upward to the anti-backflow valve 3. After passing through the anti-backflow valve 3, it enters the engine oil circuit to provide clean engine oil lubrication for various engine components. The anti-backflow valve 3 can prevent the oil from flowing back when the engine stops working.

[0032] When the filter paper 7 becomes clogged, obstructing the flow of engine oil, the bypass valve 11 at the bottom inside will open. Since large impurities are blocked on the outside of the filter element by the filter holes 10 on the separator plate 4, the opened bypass valve 11 will not allow large impurities to enter the subsequent oil circuit.
