Description

Technical Field

[0001] This utility model relates to the field of oil suction and return filter technology, specifically an integrated oil suction and return filter. Background Technology

[0002] Integrated suction and return oil filters are commonly used in the hydraulic systems of self-propelled machines, such as those equipped with hydrostatic transmission and combined working hydraulic systems. These filters combine the functions of a return oil filter and a suction or pressure oil filter. The suction filter is generally installed at the oil pump's suction port to protect the oil pump from damage by larger mechanical impurities. Chinese patent CN221867571U discloses a suction oil filter, including a filter body. One end of the top of the filter body has an oil inlet channel, and the other end has an oil outlet channel. An oil inlet pipe is fixed to the oil inlet channel, and an oil outlet pipe is fixed to the oil outlet channel. The filter body contains a filtration mechanism, which includes a cylinder vertically positioned at the center of the filter body. The top of the cylinder is fixedly connected to the top surface of the filter body. Several filter holes are formed in the middle of the cylinder. A turntable is located at the bottom of the cylinder. The side wall of the cylinder is connected to the oil outlet pipe. The top of the turntable is rotatably connected to the cylinder, and the bottom of the turntable is rotatably connected to the bottom surface of the filter body. This design solves the problem of existing technologies where the connecting shaft is connected to the inner cavity of the filter body, resulting in a gap at the connection point. Even with proper sealing, oil leakage will occur after prolonged use.

[0003] Based on existing solutions and actual production and processing applications, existing integrated oil suction and return filters, due to their working environment and operational characteristics, experience pressure fluctuations during pumping or discharging, which causes localized stress concentration in the housing and makes it prone to deformation. This affects the sealing surface and the compression state of the filter element. Therefore, we propose an integrated oil suction and return filter to solve the problems mentioned above. Utility Model Content

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: The integrated oil suction and return filter improves the pressure resistance and bending stiffness of the shell through the cooperation between the reinforcing hoop and the reinforcing rib, reduces deformation under high pressure and pressure pulse conditions, thereby reducing the probability of leakage. At the same time, the quick-connect oil inlet and quick-connect oil outlet can realize multi-point oil return, oil injection or diversion circuit, thereby simplifying the pipeline layout and ensuring that the system can still operate through other ports when a failure occurs at one port. Then, the filter cartridge can reduce single-point high pressure and local pressure peaks, and reduce the scouring stress of the sealing surface and filter element. The cooperation between the filter cartridge and the filter tube can effectively remove pollutants and moisture of different particle sizes. 1.

The cover plate allows oil to enter the interior of the filter cartridge separately, and a second filter element is placed at the angle of the partition plate, which can then filter the oil.

The filter cartridge can reduce single-point high pressure and local pressure peaks, and reduce the scouring stress on the sealing surface and filter element. The cooperation between the filter cartridge and the filter tube can effectively remove contaminants and moisture of different particle sizes, thereby improving the cleanliness of the oil.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In order to solve the technical problem that existing integrated oil suction and return filters cause pressure fluctuations during pumping or discharging, resulting in local stress concentration in the housing and affecting the compression state of the sealing surface and filter element, this embodiment discloses the following technical content; Please see Figures 1-6 The integrated oil suction and return filter includes a filter body 1, a reinforcing hoop 2, a reinforcing rib 3, a mounting connector 4, a first connector 5, a quick-connect oil inlet 6, a second connector 7, a quick-connect oil outlet 8, a first insert rod 9, a filter tube 10, a first filter element 11, a second insert rod 12, a filter cylinder 13, a partition plate 14, a second filter element 15, a cover plate 16, and a nut 17. like Figure 1 and Figure 2As shown, when the filter body 1 is filtering oil, a detachable mounting connector 4 is installed at the upper end of the filter body 1. A first connector 5 is fixedly installed on the top of the mounting connector 4, and the first connector 5 has a cross-shaped structure. Quick-connect oil inlets 6 are provided on all four sides of the first connector 5. A second connector 7 is fixedly installed at the rear end of the mounting connector 4, and quick-connect drain outlets 8 are provided on both the left and right ends of the second connector 7. When filtering oil, the input and output ends of the oil circuit can be inserted into the filter body according to the actual filtration requirements. The quick-connect injection port 8 is inserted into the interior of the filter body 1, and the oil passage is connected to the second connector 7. The oil passage can be injected and discharged through the cooperation between the second connector 7 and the quick-connect injection port 8. At the same time, the oil passage can be inserted into the quick-connect oil inlet 6 and connected to the first connector 5. The oil passage can be injected into the interior of the filter body 1 through the cooperation between the first connector 5 and the quick-connect oil inlet 6. The quick-connect oil inlet 6 and the quick-connect injection port 8 can realize multi-point oil return, oil injection or diversion circuit, and can keep the system running through other ports even if one port fails. like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when the filter body 1 is connected to the oil circuit via the quick-connect oil inlet 6 and quick-connect oil outlet 8, and oil is injected into the filter body 1 and discharged to the outside of the filter body 1, the filter cartridge 13 is sleeved and connected to the body of the second insert rod 12, and a partition plate 14 is fixedly installed inside the filter cartridge 13. The partition plate 14 is set in a "rice" shaped structure, allowing the second filter element 15 to be placed at the included angle of the partition plate 14. The body of the second insert rod 12 is connected to the nut 17 by threads, so the cover plate 16 can be tightly fitted to the top of the filter cartridge 13 through the cooperation between the second insert rod 12 and the nut 17. When oil is injected into the filter body 1, the cover plate 16 discharges the oil into the interior of the filter cartridge 13, because the partition plate 14 divides the inner cavity of the filter cartridge 13 into multiple chambers. The oil enters multiple chambers and is filtered by the second filter element 15 in each chamber. Simultaneously, the multiple independent filtration chambers within the filter cartridge 13 allow for oil diversion, preventing filtration degradation due to a single input / output. A first insert rod 9 is fixedly installed at the bottom inner part of the filter body 1, and a filter tube 10 is sleeved and connected to the outside of the first insert rod 9. The first filter element 11 is fixedly installed in an array inside the filter tube 10. This allows the oil filtered by the second filter element 15 to undergo further filtration through the interaction between the filter tube 10 and the first filter element 11. The filter cartridge 13 reduces single-point high pressure and local pressure peaks, and decreases the scouring stress on the sealing surface and filter element. Furthermore, the interaction between the filter cartridge 13 and the filter tube 10 effectively removes contaminants and moisture of different particle sizes. like Figure 1 Figure 2 , Figure 3 and Figure 5 As shown, when filtering oil, the reinforcing hoop 2 has reinforcing ribs 3 fixedly installed in an array on the outer side of the upper end of the filter body 1 through the reinforcing hoop 2. This makes the reinforcing ribs 3 evenly distributed on the outer side of the filter body 1 and fixedly connected to the filter body 1. The cooperation between the reinforcing hoop 2 and the reinforcing ribs 3 improves the pressure resistance and bending stiffness of the shell and reduces the increase in the sealing surface gap caused by deformation, thereby reducing the probability of leakage.
