Description

TECHNICAL FIELD

[0001] The utility model relates to oil liquid filtration field, in particular to an adsorption type oil body filter. BACKGROUND

[0002] Hydraulic systems and hydrodynamic braking systems are crucial in industrial and engineering fields, as they often bear the responsibility of transmitting power and controlling speed. However, during operation, impurities and metal particles in the oil gradually accumulate, leading to decreased device performance and premature wear. Traditional filter designs are single-layered, relying mainly on a layer of filter paper or mesh for filtration, which is ineffective in handling small particle impurities. Additionally, the accumulation of impurities on the mesh reduces the oil's passage rate, and the mesh is prone to breakage under high pressure, increasing the risk of filtration failure. These issues not only affect the efficiency of device operation but also may lead to high maintenance costs and unexpected downtime, causing economic losses to enterprises. SUMMARY

[0003] To solve the above technical problems, the utility model provides an adsorption type oil body filter, which filters oil twice through a multi-layer circulation structure and a mesh, solving the problem of poor filter performance in the prior art.

[0004] To solve the above technical problems, the utility model provides a technical scheme: an adsorption type oil body filter, comprising a filter housing, a filter core body, and an oil cleaning pipe, characterized in that: one end of the oil cleaning pipe is located in the end of the turbid oil pipe and coaxial with it, and the other end of the oil cleaning pipe extends towards the wall of the turbid oil pipe and penetrates out.

[0005] The filter core body is disc-shaped, and a cleaning oil through hole is provided at the center, with both ends of the cleaning oil through hole being connected to the filter mesh and the one end of the oil cleaning pipe respectively, a plurality of concentric circular ring-shaped supports are coaxially arranged on the filter core body, the circular ring-shaped supports are sleeved outside the filter mesh, and gaps are provided between the circular ring-shaped supports.

[0006] The filter housing is a cylinder with one open end and one closed end, a plurality of concentric circular ring-shaped partitions are coaxially arranged on the closed end of the filter housing, gaps are provided between the circular ring-shaped partitions, the open end of the filter housing is sleeved on the filter core body and is screwed to the end of the turbid oil pipe to block the end of the turbid oil pipe, and the circular ring-shaped partitions and the circular ring-shaped supports are staggered and extend into the gaps of each other, forming annular interlayers that are connected in sequence.

[0007] A fabric adsorbent cotton layer that does not contact the circular ring-shaped partitions is wrapped outside the circular ring-shaped supports.

[0008] Further, the filter core body and the circular ring-shaped supports are made of metal, and a permanent magnet snap ring is arranged between the filter mesh and the cleaning oil through hole.

[0009] Further, the annular partition thickness, the annular partition spacing, the annular support thickness and the annular support spacing are matched, so that the oil passage cross-sectional area of each annular interlayer is equal.

[0010] Further, the filter element body on the oil cleaning pipe side is conical.

[0011] Further, the filter screen is conical.

[0012] The beneficial effects of the utility model are:

[0013] 1. The application has the characteristics of quick disassembly, so that the user can easily maintain and replace it, and before the secondary fine filtration of oil, it also has the function of pre-adsorbing metal particles and small impurities, thereby effectively improving the filtering effect and the service life of the fine filter element, reducing the difficulty of maintenance and operation cost, and solving the problem of low service life of the filter element caused by the accumulation of many impurities on the filter element.

[0014] 2. In the application, the filter element body and the annular support body are made of metal, the permanent magnet snap ring is arranged at the oil cleaning through hole and is tightly fixed by the screen, and after contacting the metal part of the filter element body, the filter element body is magnetized, thereby better adsorbing metal particles.

[0015] 3. In the application, the filter housing and the annular partition are different in material from the adsorbing cotton layer, so that the resistance to fluid is different. Since the liquid itself has viscosity and friction, it will be difficult to form laminar flow in the chamber, but will form chaotic turbulent flow. Therefore, each part will be in contact with the adsorbing cotton layer during fluid flow, thereby realizing ideal contact adsorption filtration effect.

[0016] 4. In the application, the multiple annular partitions and the annular supports greatly extend the adsorption area in a small volume, improve the filtration efficiency per unit volume, and have little effect on the hydraulic system resistance because the oil does not need to directly penetrate through the filter screen or filter paper in the early stage.

[0017] 5. In the application, the annular partition thickness, the annular partition spacing, the annular support thickness and the annular support spacing are matched, so that the oil passage cross-sectional area of each annular interlayer is equal, avoiding sudden changes in pressure in the filter caused by changes in cross-sectional area.

[0018] 6. In the application, the filter element body on the oil cleaning pipe side is conical, which plays a guiding role when turbid oil enters the filter, thereby reducing the impact of the liquid on the plane, and further reducing the resistance in the hydraulic system.

[0019] 7、The filter screen in the application is a conical structure, which increases the contact area of the filter screen and oil, and improves the filtering efficiency.

[0020] In order to make the above and other objects, features and advantages of the present application more apparent, the following preferred embodiments will be described in detail, and the accompanying drawings will be described as follows. BRIEF DESCRIPTION OF DRAWINGS

[0032] The names of the messages or information exchanged between the plurality of devices in the embodiments of the present application are only for illustrative purposes, and are not intended to limit the scope of these messages or information. Example one

[0033] As shown in Figures 1-7 An adsorption type oil filter, comprising a filter housing 1, a filter core body 2 and a clean oil pipe 3, one end of the clean oil pipe 3 is in the end of a turbid oil pipe 4 and coaxial with the turbid oil pipe 4, the other end of the clean oil pipe 3 extends to the pipe wall of the turbid oil pipe 4 and penetrates out.

[0034] The filter core body 2 is disc-shaped, and a clean oil through hole 5 is arranged at the center of the disc, the two ends of the clean oil through hole 5 are respectively clamped with a filter screen 6 and screwed with one end of the clean oil pipe 3, a plurality of concentric circular ring-shaped support bodies 7 are coaxially arranged on the filter core body 2, the circular ring-shaped support bodies 7 are sleeved outside the filter screen 6, and gaps are formed between the circular ring-shaped support bodies 7; the filter housing 1 is a cylindrical structure with one end open and one end closed, a plurality of concentric circular ring-shaped partition plates 8 are coaxially arranged on the closed end in the filter housing 1, gaps are formed between the circular ring-shaped partition plates 8, the open end of the filter housing 1 is sleeved on the filter core body 2 and screwed with the end of the turbid oil pipe 4 to block the end of the turbid oil pipe 4, and the circular ring-shaped partition plates 8 and the circular ring-shaped support bodies 7 are staggered and extend into the gaps of each other, forming annular interlayers 9 that are sequentially connected; the plurality of circular ring-shaped partition plates and the circular ring-shaped support bodies 7 are embedded in each other, so that the adsorption area is greatly extended in a small volume, the filtering efficiency per unit volume is improved, and the influence on the hydraulic system resistance is small because the oil liquid does not need to directly penetrate through the filter screen 6 or filter paper in the early stage.

[0035] The outer side of the circular ring-shaped support body 7 is wrapped with a fabric adsorption cotton layer 10 which does not contact the circular ring-shaped partition plate 8; the filter housing 1 and the circular ring-shaped partition plate 8 are different in material from the fabric adsorption cotton layer 10, resulting in different resistance to the fluid, because the liquid itself has viscosity and friction, it will be difficult to form laminar flow during flow in the chamber, but form relatively chaotic turbulent flow, therefore, each part will be uniformly contacted with the fabric adsorption cotton layer 10 during the fluid flow process, thereby realizing a relatively ideal contact adsorption filtering effect.

[0036] Among them, the filter screen 6 is a conical structure; the filter screen 6 is a conical structure, which increases the contact area of the filter screen 6 with the oil liquid and improves the filtering efficiency. Example two

[0037] As shown in Figure 3As shown, this embodiment is obtained by adding technical features such as a permanent magnet retaining ring on the basis of embodiment one. The remaining technical features are the same as those of embodiment one, and the similarities are not repeated here. Among them, the difference between this embodiment and embodiment one is that: the filter element body 2 and the annular support body 7 are made of metal, and a permanent magnet retaining ring is provided between the filter screen 6 and the oil clearing through hole 5.

[0038] In this embodiment, the filter element body 2 and the annular support body 7 are made of metal. The permanent magnet retaining ring is arranged at the oil clearing hole 5 and is pressed and fixed by the screen. After contacting the metal part of the filter element body 2, the filter element body 2 is magnetized, thereby better adsorbing metal particles. Example 3

[0039] like Figure 3 As shown, this embodiment is obtained by further describing the technical features such as the annular partition 8 and the annular support body 7 on the basis of the second embodiment. The remaining technical features are the same as those of the second embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the second embodiment is that the thickness of the annular partition 8, the spacing between the annular partitions 8, the thickness of the annular support body 7, and the spacing between the annular support bodies 7 are matched, so that the oil-passing cross-sectional area of ​​each annular interlayer 9 is equal.

[0040] In this embodiment, the oil-passing cross-sectional area of ​​each annular interlayer 9 is made equal to avoid sudden pressure changes in the filter due to changes in the cross-sectional area. Example 4

[0041] like Figure 3 As shown, this embodiment is obtained by further describing the technical features such as the filter element main body 2 on the basis of the third embodiment. The remaining technical features are the same as those of the third embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the third embodiment is that the filter element main body 2 on the side of the oil cleaning pipe 3 is conical 12.

[0042] In this embodiment, the filter element body 2 on the side of the oil cleaning pipe 3 in the application is conical 12, which plays a diversion role when the turbid oil enters the filter, thereby reducing the impact of the liquid on the plane and reducing the resistance in the hydraulic system.

[0043] The use process of the overall technical scheme formed by the above embodiments is as follows: the turbid oil in the turbid oil pipe 4 enters the filter housing 1 under the guidance of the taper 12 on the filter core body 2, and the turbid oil flows in the annular interlayer 9 formed by the circular ring-shaped partition plate 8 and the circular ring-shaped support body 7 in sequence, and due to the different materials of the filter housing 1, the circular ring-shaped baffle and the fabric adsorption cotton layer 10, the turbid oil will not form a laminar flow in the annular interlayer 9, but a relatively chaotic turbulent flow, so that each part of the turbid oil contacts the fabric adsorption cotton layer 10, thereby realizing a relatively ideal contact adsorption filtering effect and achieving the first filtering of the turbid oil, and then the turbid oil is filtered for the second time through the filter screen 6 to become clean oil, and the clean oil enters the clean oil pipe 3 through the clean oil through hole 5, and the other end of the clean oil pipe 3 extends to the wall of the turbid oil pipe 4 and penetrates out to be connected with the next stage of the oil circuit system to output the filtered oil.

[0044] In the first filtering of the turbid oil, the metal part of the filter core body 2 is magnetized after contacting the permanent magnet snap ring, and the metal particles in the turbid oil are adsorbed, and since the large-particle impurities and metal particles have been fully adsorbed in the first filtering, the impurities generated in the second filtering are less, and the service life of the screen is effectively prolonged.

[0045] Disassembly and replacement: the structure can be disassembled, when the filter impurities accumulate to the limit and need to be cleaned (preferably regular cleaning), the filter housing 1 is first rotated and dismounted from the turbid oil pipe 4, at this time the filter core body 2 is exposed, and the fabric adsorption cotton layer 10 of the filter core body 2 can be selectively flushed or directly replaced according to the situation; when the filter core body 2 is replaced, the filter core body 2 should be first rotated and dismounted from the clean oil pipe 3, then the filter screen 6 is dismounted, so that the permanent magnet snap ring is dismounted, the permanent magnet snap ring is installed in the new filter core body 2, and finally the filter core body 2 and the filter housing 1 are mounted back.

[0046] The application is particularly suitable for filtering and processing oil in hydraulic systems, hydraulic retardation systems and other equipment, and automatic processing equipment such as numerical control machine tools. In specific application fields, the cleanliness standard of oil is extremely strict, which has a decisive influence on guaranteeing the efficient operation and long-term stability of mechanical equipment.

[0047] Note that the above is only a preferred embodiment of the present application and the technical principle applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the protection scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the concept of the present application, and the scope of the present application is determined by the scope of the appended claims.
