Therefore, it is one of the most important filters for controlling the pollution cleanliness of the system.

[0003] The existing oil return filters cannot pre-treat the oil entering the oil return filter body, resulting in an excessive filtration burden on the oil return filter body, which easily leads to too fast a clogging speed of the filter screen of the oil return filter, thereby resulting in poor quality of the filtered oil of the oil return filter and reduced service life. Therefore, an oil return filter with a bypass filtration function is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0006] The disassembly mechanism includes a base, a clamping block, a receiving box, a plug rod, a positioning rod, an electric push rod, a limiting plate, an extension block and a baffle. The base is fixedly installed inside the bypass filter body. The clamping block is fixedly installed at the bottom of the filter element. The receiving box is installed on the left side of the base. The plug rod is installed on the left side of the clamping block. The positioning rod is fixedly installed inside the receiving box. The electric push rod is installed inside the receiving box. The right side of the electric push rod is connected to the limiting plate. The extension block is fixedly installed at the bottom of the sealing cover. The baffle is rotatably connected to the outside of the bypass filter body.

[0007] Further, an oil inlet pipe is fixedly installed at the top of the filter element. A feeding hopper is arranged at the bottom of the bypass filter body. The right side of the feeding hopper is connected to an oil guide pipe.

[0008] Further, one side of the oil guiding pipe away from the blanking hopper is connected to the left side of the oil return filter body, and a clamping groove is formed inside the base.

[0009] Further, the clamping block is engaged with the base, and one side of the insertion rod away from the clamping block extends into the accommodating box.

[0010] Further, the positioning rod penetrates through the insertion rod, a groove is formed inside the limiting plate, and one side of the positioning rod away from the inner wall of the accommodating box extends into the groove.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] 1. For the oil return filter with a bypass filtering function, the oil is initially filtered by setting the bypass filter body, and the filtered oil enters the oil return filter body through the oil guiding pipe for re - filtering. This not only has a better filtering effect, but also prevents the filter screen inside the oil return filter body from being blocked, extending the service life of the oil return filter body. By setting the disassembly mechanism, the structures of the disassembly mechanism cooperate with each other to ensure more convenient replacement of the filter element, thus reducing the impact on the use of the oil return filter body.

[0014] 2. For the oil return filter with a bypass filtering function, by setting the base, the filter element is initially positioned by inserting the clamping block into the base. By setting the accommodating box, it is convenient to lock the insertion rod. When in use, first insert the insertion rod into the accommodating box and pass through the positioning rod for preliminary limiting of the insertion rod. By setting the electric push rod, the controller drives the electric push rod to start, which can push the limiting plate to move to the right, thereby locking the positioning rod to prevent the clamping block from shaking. By setting the extension block, insert the extension block into the accommodating groove, so that the sealing cover at the top closes the bypass filter body. At this time, rotate the baffle plate and fix the baffle plate stably with the fixing screw. BRIEF DESCRIPTION OF THE DRAWINGS
