[0032] like Figures 1-6 The oil filter machine with replaceable filter element shown in the figure comprises: a chassis 1, an oil inlet tank 5, an oil outlet tank 8, a filter element switching assembly, a first driving member 15 and a second driving member 16.

[0033] like Figure 1 and Figure 2 As shown, a door 2 that can be opened or closed is provided on the front side of the chassis 1, an oil inlet pipe 3 is provided on the top of the chassis 1, and an oil drain pipe 4 is provided on the bottom of the chassis 1.

[0034] like Figure 2-Figure 4 As shown, the oil inlet tank 5 is arranged inside the chassis 1, the bottom of the oil inlet tank 5 is open, and a bellows 6 is provided on the top of the oil inlet tank 5, the bellows 6 is connected to the oil inlet pipe 3, and a control valve 7 is provided between the bellows 6 and the oil inlet pipe 3; the oil drain tank 8 is fixedly arranged inside the chassis 1, the oil drain tank 8 is located directly below the oil inlet tank 5 and is separated from the oil inlet tank 5, the upper side of the oil drain tank 8 is open, and the bottom of the oil drain tank 8 is connected to the oil drain pipe 4.

[0035] like Figure 3-Figure 5As shown, the filter element switching assembly includes a slide 9 and a filter element 10. The filter element 10 is a plate type filter element 10. The outer periphery of the filter element 10 is provided with a frame 11. The slide 9 can be slid left and right in the gap between the oil inlet tank 5 and the oil discharge tank 8. Two placement grooves, one on the left and one on the right, are provided on the slide 9. The filter element 10 can be detachably placed horizontally in each placement groove. The outer frame of the filter element 10 is provided with a flange 12, and the flange 12 is supported on the upper edge of the slide 9.

[0036] A left limit switch 13 and a right limit switch 14 are provided in the chassis 1. The first driving member 15 is connected to the slide 9 to drive the slide 9 to slide between the left limit switch 13 and the right limit switch 14. When the slide 9 slides to the left limit switch 13, the filter element 10 on the right side of the slide 9 is located between the oil inlet tank 5 and the oil drain tank 8. When the slide 9 slides to the right limit switch 14, the filter element 10 on the left side of the slide 9 is located between the oil inlet tank 5 and the oil drain tank 8; the second driving member 16 is connected to the oil inlet tank 5, and the second driving member 16 is used to drive the oil inlet tank 5 to move up and down to tighten or loosen the outer frame of the filter element 10 below.

[0037] Specifically, the working process of this device is as follows:

[0038] When the device is operating normally, one of the left and right filter elements 10 will always be located between the oil inlet tank 5 and the oil outlet tank 8. Figure 6 For example, assuming that the filter element 10 on the right is located between the oil inlet tank 5 and the oil drain tank 8, during the operation of the device, the control valve 7 is in the normally open state. At this time, the lubricating oil flows from the oil inlet pipe 3 into the oil inlet tank 5, and will automatically be filtered and purified through the filter element 10 downward, and then automatically flow to the oil drain tank 8 below, and finally be discharged from the oil drain pipe 4.

[0039] The filter element 10 is a plate-type filter element 10 with a simple structure and a large filtration flow rate. After filtering and purifying the lubricating oil, it can remove moisture and impurities from the lubricating oil, thereby preventing the lubricating oil from emulsifying and failing. Furthermore, the filter element 10 in this device is placed horizontally, and the lubricating oil automatically flows through the filter element 10 from top to bottom under its own weight for filtration and purification. The lubricating oil flows smoothly throughout the filtration process, resulting in higher filtration efficiency.

[0040] When the device has been running for a period of time and the filter element 10 needs to be replaced, the control valve 7 is temporarily closed first, and then the second drive member 16 drives the oil inlet tank 5 to move upward to loosen the original filter element 10. At this time, the first drive member 15 drives the slide 9 to move to the right, so that the new filter element 10 on the left is moved between the oil inlet tank 5 and the oil drain tank 8, and the original old filter element 10 on the right is moved out to the right. Finally, the second drive member 16 drives the oil inlet tank 5 to move downward to reset and press the new filter element 10. The control valve 7 is reopened and the device can continue to operate.

[0041] At this time, the operator can open the door 2, remove the old filter element 10 and replace it with a new filter element 10 for next use. This method of removing and replacing the filter element 10 is simple and convenient, and the device remains in normal operation while removing and replacing the old filter element 10. Therefore, the filter element 10 can be replaced without stopping the device, avoiding additional losses caused by long-term shutdown of the device.

[0042] In this device, if Figure 5 As shown, the outer frame of the filter element 10 has a flange 12, and the filter element 10 can be directly placed in the placement groove. At this time, the flange 12 is supported on the upper edge of the slide 9, which is very convenient to use.

[0043] In this device, in order to avoid oil leakage during filtration, the oil inlet tank 5 is pressed against the outer frame of the filter element 10, and sealing rings can be further provided at the bottom of the oil inlet tank 5 and the top of the oil drain tank 8 to improve the sealing performance.

[0044] In this device, if Figure 3 and Figure 4 As shown, a bellows 6 is provided between the top of the oil inlet tank 5 and the oil discharge pipe 4 . The bellows 6 is retractable and thus does not affect the up and down movement of the oil inlet tank 5 .

[0045] In this device, in order to accurately control the distance that the slide 9 slides left and right, a left limit switch 13 and a right limit switch 14 are provided in the chassis 1. Figure 2 As shown, the left limit switch 13 is provided on the inner wall of the chassis 1, the right limit switch 14 is provided on the oil drain tank 8, and a detection block 17 is provided on the slide 9. The detection block 17 is located between the left limit switch 13 and the right limit switch 14. Therefore, when the detection block 17 moves to a certain limit switch position, the first drive block stops working and moves in the opposite direction at the next start.

[0046] In actual application, the first driving member 15 includes a first electric telescopic rod, one end of which is fixedly connected to the detection block 17, and the other end is fixedly connected to the oil drain tank 8 through a support, thereby driving the slide 9 to slide left and right through the extension and retraction of the first electric telescopic rod.

[0047] In this device, if Figure 3 and Figure 4 As shown, a horizontal support rail 18 is provided in the chassis 1 , and there are two support rails 18 arranged one in front and one behind. The slide 9 is supported on the support rails 18 , thereby providing stable support for the slide 9 .

[0048] In this device, if Figure 3 and Figure 4As shown, the second driving member 16 includes a second electric telescopic rod, one end of which is fixedly connected to the chassis 1, and the other end is fixedly connected to the oil inlet tank 5, so that the oil inlet tank 5 can be driven to move up and down by the extension and contraction of the second electric telescopic rod.

[0049] In summary, the present device is used to filter and purify lubricating oil, removing moisture and impurities from the lubricating oil to prevent the lubricating oil from emulsifying and failing. The filter element 10 used in the present device is a plate filter element 10. This filter element 10 has a simple structure and a large filtration flow rate. The filter element 10 is placed horizontally, and the lubricating oil automatically flows from top to bottom through the filter element 10 by its own weight for filtration and purification. The lubricating oil flows smoothly during the entire filtration process, and the filtration efficiency is higher. In addition, two filter elements 10 are provided in the present device, which can be switched in position. Therefore, when the old filter element 10 is disassembled and replaced, the device is still in normal operation. Therefore, the filter element 10 can be replaced without stopping the device, avoiding additional losses caused by long-term shutdown of the device.

[0050] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations to these embodiments without departing from the principles and purpose of the present invention are all within the scope of protection of the claims of the present invention.
