In the prior art, the single-cylinder filter 300 and the double-cylinder filter are frequently used in a lubricating oil path, and both can play a role in filtering oil. When the single-cylinder filter 300 is used, although the cost is low, the filter element can not be replaced on line without stopping. When the double-cylinder filter is used, the filter element can be replaced on line without stopping, but the cost is higher.
In view of this, the designer provides a filter device, can also realize not shutting down on line and change the filter core under the prerequisite of reduce cost, compromise low cost and operating stability.
Referring to fig. 1, in the present embodiment, the filtering apparatus includes an oil inlet pipe 100, an oil outlet pipe 200, a single-tube filter 300 and a switching pipeline 400, the oil inlet pipe 100 is connected to an oil inlet of the single-tube filter 300, the oil outlet pipe 200 is connected to an oil outlet of the single-tube filter 300, the switching pipeline 400 is simultaneously connected to the oil inlet pipe 100 and the oil outlet pipe 200, and the oil inlet pipe 100 is selectively communicated with the oil inlet or the switching pipeline 400; the outlet line 200 may selectively communicate with an outlet port or a switching line 400.
It will be appreciated that the selective communication of the oil inlet pipe 100 with the oil inlet and the switching line 400 can be achieved by providing a first valve assembly, and the selective communication of the oil outlet pipe 200 with the oil outlet or the switching line 400 can be achieved by providing a second valve assembly.
In this embodiment, the operating principle of the filtering apparatus is as follows:
when the filtering apparatus is normally used, the oil inlet pipe 100 is communicated with the oil inlet of the single-cartridge filter 300, and the oil inlet pipe 100 is blocked from the switching line 400, and at the same time, the oil outlet pipe 200 is communicated with the oil outlet of the single-cartridge filter 300, and the oil outlet pipe 200 is blocked from the switching line 400. Thus, oil entering from the oil inlet pipe 100 can enter the single-cylinder filter 300 from the oil inlet, and after being filtered, the oil enters the oil outlet pipe 200 from the oil outlet. When the filter element needs to be replaced, the oil inlet of the oil inlet pipe 100 and the oil inlet of the single-cylinder filter 300 are blocked, the oil inlet pipe 100 is communicated with the switching pipeline 400, meanwhile, the oil outlet pipe 200 is blocked from the oil outlet of the single-cylinder filter 300, and the oil outlet pipe 200 is communicated with the switching pipeline 400, so that oil input by the oil inlet pipe 100 can bypass the single-cylinder filter 300 and is discharged from the oil outlet pipe 200, and at the moment, the filter element can be replaced without stopping on line. In this embodiment, the single-cartridge filter 300 is matched with a pipeline to realize on-line non-stop filter element replacement, and compared with a double-cartridge filter, the cost is lower.
In this embodiment, optionally, the filter device further includes a three-way valve 500, a three-way joint 600, and a one-way valve 700. The three-way valve 500 has a first port 510, a second port 520 and a third port 530, the first port 510 is communicated with the oil inlet pipe 100, the second port 520 is communicated with the oil inlet of the single cartridge filter 300, and the third port 530 is communicated with the first port of the switching line 400. And, by adjusting the state of the three-way valve 500, the first port 510 and the second port 520 can be communicated and the first port 510 and the third port 530 can be blocked, at this time, the oil in the oil inlet pipe 100 can enter the single-tube filter 300. Meanwhile, after the three-way valve 500 is adjusted, the first port 510 and the third port 530 can be communicated while the first port 510 and the second port 520 are blocked, and at this time, the oil input from the oil inlet pipe 100 can enter the switching pipeline 400 to bypass the single-cylinder filter 300.
Specifically, the three-way joint 600 includes a fourth port 610, a fifth port 620 and a sixth port 630, the fourth port 610 is communicated with the oil outlet, and the check valve 700 is disposed on a pipeline where the fourth port 610 is communicated with the oil outlet, and the check valve 700 only allows fluid to flow from the oil outlet to the fourth port 610. The flow line 200 communicates with the fifth port 620, and the second port of the switching line 400 communicates with the sixth port 630. So design, no matter single cylinder filter 300 is in normal operating condition or is in the state of renew cartridge filter 300, fluid all can not flow back to in the single cylinder filter 300 from the oil-out, the operation is reliable and stable.
