Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a double-tube filter device. Background Art

[0002] The duplex filter is also called the duplex return oil line filter. It is mainly installed on the return oil line of the hydraulic system. The abrasive particles and other impurities generated by various hydraulic components during operation can be intercepted by the oil filter installed in the return oil line to avoid returning to the oil tank and being sucked into the hydraulic pump again.

[0003] According to the patent with announcement number CN210993230U, a new type of double-barrel filter is disclosed. The new type of double-barrel filter includes a first filter device and a second filter device, a reversing valve is connected between the first filter device and the second filter device, the first filter device and the second filter device have the same structure, the filter device includes a cylinder and a filter element, the cylinder is provided with a liquid inlet and a liquid outlet, the filter element is arranged inside the cylinder, the filter element divides the cylinder into a liquid inlet cavity and a liquid outlet cavity, the liquid inlet cavity is connected to the liquid inlet, and the liquid outlet cavity is connected to the liquid outlet; the reversing valve is composed of an oil inlet reversing valve and an oil outlet reversing valve.

[0004] The above scheme has a compact structure, good filtering effect, and is convenient for removing impurities. However, the above scheme has limitations in actual use. By setting a drain port, impurities in the filter element can be discharged. However, after a long period of use, the filter element will be more or less blocked by dirt or become aged and rusty, affecting its filtering effect and delaying the work progress. This requires it to be taken out for cleaning or replacement. In the above device, the filter element and the cylinder are fixedly connected, which makes it difficult to take out the filter element and inconvenient for the staff to clean or replace the filter element. For this reason, we provide a double-cylinder filter device to solve the above problems. Utility Model Content

[0030] The sealing cover 401 can be covered on the outside of the cylinder 1 to improve the sealing performance of the cylinder 1. The movable groove 403 can be used for the movement of the movable plate 407. The sealing cover 401 and the mounting block 406 are fixed by bolts. When the filter element 6 is taken out, the bolts can be removed to release the fixation between the sealing cover 401 and the mounting block 406, and the filter element 6 can be cleaned or replaced.

[0031] Two symmetrical mounting blocks 406 are fixedly connected to the bottom surface of the sealing cover 401, and the side surfaces of the two mounting blocks 406 close to each other are fixedly connected to the outer surface of the filter element 6. The outer surfaces of the two mounting blocks 406 are inserted into the interior of the mounting groove 404, and the interiors of the two slide grooves 405 are slidably connected to movable plates 407, and the side surfaces of the two movable plates 407 away from the mounting blocks 406 are fixedly connected to elastic members 408.

[0032] The elastic member 408 is a spring, and under the action of its elastic force, the insertion rod 409 can be quickly reset.

[0033] One end of the two elastic members 408 away from the movable plate 407 is fixedly connected to the inner wall of the slide groove 405 , and one side of the two movable plates 407 close to the mounting block 406 is fixedly connected to the insertion rod 409 .

With the movement of the movable plate 407, the movable plate 407 is compressed, so that the movable plate 407 generates elastic force, which can be used to reset the insertion rod 409 when installing the filter element 6. Then, the handle 402 is held, and the sealing cover 401 is moved upward to drive the mounting block 406 to move a certain distance, so that the jack on the mounting block 406 and the insertion rod 409 are aligned. Misalignment, at this time, the force acting on the movable plate 407 can be removed, and the sealing cover 401 can be continued to be moved upward until the filter element 6 is completely taken out, and because the sealing cover 401 and the mounting block 406 are fixed by bolts, when the filter element 6 is taken out, the bolts can be removed to release the fixation between the sealing cover 401 and the mounting block 406, and the filter element 6 can be cleaned or replaced, which solves the problem that the cylinder 1 and the filter element 6 in the existing device are fixedly connected, which makes it difficult to take out the filter element 6, and achieves the purpose of facilitating the staff to clean or replace the filter element 6.

The other end of the second tee 504 is fixedly connected to the oil outlet pipe 505 .

[0039] Valves are provided inside the oil inlet conduit 503 and the oil outlet conduit 506 .

[0040] When in use, the oil enters the cylinder 1 through the oil inlet pipe 502, the first tee 501 and the oil inlet conduit 503 for filtration, and the filtered oil is discharged from the oil outlet conduit 506, and re-enters the oil tank through the second tee 504 and the oil outlet pipe 505. When one of the filters is blocked, it is only necessary to close the valves on the oil inlet conduit 503 and the oil outlet conduit 506 connected to the filter, and the other filter will continue to work without stopping the operation of the device.

[0041] A filter element 6 is arranged inside the cylinder 1 .

[0042] The surface of the filter element 6 is provided with an oil inlet, which is opposite to the pipe opening of the oil inlet conduit 503 and is larger than the pipe opening of the oil inlet conduit 503. The oil transported by the oil inlet conduit 503 will enter the filter element 6 through the oil inlet for filtration.

[0043] Working principle: When in use, the oil enters the cylinder 1 through the oil inlet pipe 502, the first tee 501 and the oil inlet conduit 503 for filtration, and the filtered oil is discharged from the oil outlet conduit 506, and re-enters the oil tank through the second tee 504 and the oil outlet pipe 505. When one of the filters is blocked, it is only necessary to close the valves on the oil inlet conduit 503 and the oil outlet conduit 506 connected to the filter, and the other filter will continue to work without stopping the operation of the device. When in use, the movable plate 407 is moved inside the movable groove 403 and the slide groove 405 to drive the insertion rod 409 to move until the insertion rod 409 is completely out of the mounting block 406, and the limit of the mounting block 406 can be released. With the movement of the movable plate 407, the movable plate 407 is compressed, so that the movable plate 407 generates elastic force, which can be used to reset the insertion rod 409 when installing the filter element 6. Then, the handle 402 is held, and the sealing cover 401 is moved upward to drive the mounting block 406 to move a certain distance, so that the jack on the mounting block 406 and the insertion rod 409 are aligned. Misalignment, at this time, the force acting on the movable plate 407 can be removed, and the sealing cover 401 can be continued to be moved upward until the filter element 6 is completely taken out, and because the sealing cover 401 and the mounting block 406 are fixed by bolts, when the filter element 6 is taken out, the bolts can be removed to release the fixation between the sealing cover 401 and the mounting block 406, and the filter element 6 can be cleaned or replaced, which solves the problem that the cylinder 1 and the filter element 6 in the existing device are fixedly connected, which makes it difficult to take out the filter element 6, and achieves the purpose of facilitating the staff to clean or replace the filter element 6.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
