Technical Field

[0001] The utility model belongs to the technical field of filter oil tanks, in particular to a filter type hydraulic oil tank of a shield machine. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a filtered hydraulic oil tank for a shield machine", and its announcement number is "CN218882628U". This patent mainly includes a hydraulic oil tank, a hydraulic pump, a filtering device and a detection device. The hydraulic oil tank includes a first oil tank and a second oil tank. The upper end of the side wall of the first oil tank is provided with an oil inlet pipe, and the lower end of the side wall of the second oil tank is provided with an oil outlet pipe. The utility model relates to the technical field of shield machines. This nested filtered hydraulic oil tank of a shield machine is provided with an oil inlet pipe at the upper end of the side wall of the first oil tank. The hydraulic oil circulated back from the hydraulic system enters the first oil tank through the oil inlet pipe for storage. The lower end of the side wall of the second oil tank is provided with an oil outlet pipe. The hydraulic oil in the second oil tank is supplied to the hydraulic system through the oil outlet pipe, forming a stable circulation, so that the hydraulic system can work stably.

[0003] There is a more prominent problem with the existing filter oil tank. After a period of use, the filter will need to be cleaned due to intercepting a large amount of impurities, or when the filter fails and needs maintenance, its complicated fixing method will cause great trouble, making it difficult for maintenance personnel to quickly remove the filter from the filter oil tank. This will undoubtedly affect the work progress, making the originally simple cleaning or maintenance work complicated, which in turn leads to a significant reduction in the overall work efficiency. Moreover, this will also increase the maintenance cost and downtime of the equipment, and have an adverse impact on production operations and other related work. Utility Model Content

The filter module 25 is adapted to the disc 23. The inner wall of the filter module 25 is provided with a first filter bin 26, a second filter bin 27 and a third filter bin 2 8. The outer wall of the filter canister 1 is fixedly connected to a rectangular frame 29, the inner wall of the rectangular frame 29 is rotatably connected to an L-shaped rod 291, the front of the L-shaped rod 291 is fixedly connected to a sealing cover 292, the sealing cover 292 is adapted to the filter canister 1, the outer wall of the filter canister 1 is rotatably connected to two rotating blocks 1 293, the outer wall of the sealing cover 292 is rotatably connected to two rotating blocks 2 294, the tops of the two rotating blocks 1 293 are fixedly connected to hydraulic cylinders 295, and the output ends of the two hydraulic cylinders 295 are fixedly connected to the two rotating blocks 294.

[0029] By setting up the filtering mechanism 2, if the filter module 25 needs to be cleaned or replaced, the two hydraulic cylinders 295 can be started. The two hydraulic cylinders 295 will cooperate with the two rotating blocks 1 293, the two rotating blocks 294, the rectangular frame 29 and the L-shaped rod 291 respectively. Under the action of this coordinated cooperation, the L-shaped rod 291 can drive the sealing cover 292 thereon to flip to a suitable angle. After the sealing cover 292 is flipped, the filter module 25 can be pulled outward to clean or replace it. Through the above-mentioned settings, the cumbersome procedures during the installation and disassembly of the filter can be effectively reduced, thereby improving the efficiency of the filter installation and saving time and labor costs.

[0030] The configuration mechanism 3 includes a double hoop 31 fixedly sleeved on the outer wall of the filter tank 1, and an oil tank 32 is fixedly sleeved on the inner wall of the double hoop 31. The inner wall of the oil tank 32 is provided with a waste oil bin 33 and a recovery bin 34. The top of the oil tank 32 is fixedly connected to an oil inlet pipe 35, which communicates with the waste oil bin 33. The inner wall of the waste oil bin 33 is fixedly connected to a liquid pump 36, and the top of the liquid pump 36 is fixedly connected to a delivery pipe 37.

The end of the oil drain pipe 38 extends into the oil tank 32. The outer wall of the oil tank 32 is fixedly connected to an oil outlet pipe 391, which communicates with the recovery bin 34.

[0031] By setting up the configuration mechanism 3, the liquid pump 36 is started. After the liquid pump 36 is started, the hydraulic oil in the waste oil tank 33 can be extracted through the delivery pipe 37 and delivered to the filter module 25 in the filter canister 1. After the hydraulic oil is delivered to the filter module 25, the motor 21 is then started. The motor 21 will rotate the filter module 25 on the outer wall of the rotating shaft 22 through the rotating shaft 22. During the rotation of the filter module 25, the hydraulic oil therein will pass through the first filter tank 26, the second filter tank 27 and the third filter tank 28 in sequence under the action of centrifugal force. These filter tanks all have specific filtering functions and can effectively remove impurities in the hydraulic oil, thereby improving the purity of the hydraulic oil. After the above-mentioned filtering steps, the impurities in the hydraulic oil have been largely removed. At this time, the valve 39 on the oil drain pipe 38 can be rotated to allow the filtered hydraulic oil in the filter canister 1 to flow along the oil drain pipe 38 into the recovery tank 34 in the oil tank 32 for recycling. This not only saves resources but also reduces production costs.

During this temporary storage process, as the equipment continues to operate, the hydraulic oil in the waste oil bin 33 will continue to increase. When the temporary storage amount of the hydraulic oil reaches a certain level, the liquid pump 36 is started. After the liquid pump 36 is started, the hydraulic oil in the waste oil bin 33 can be extracted with the help of the delivery pipe 37 and delivered to the filter module 25 in the filter tank 1. After the hydraulic oil is delivered to the filter module 25, the motor 21 is started. The motor 21 will rotate the filter module 25 on the outer wall of the rotating shaft 22 through the rotating shaft 22. During the rotation of the filter module 25, the hydraulic oil therein will be centrifuged. Under the action of force, etc., it passes through the first filter chamber 26, the second filter chamber 27 and the third filter chamber 28 in sequence. These filter chambers all have specific filtering functions and can effectively remove impurities in the hydraulic oil, thereby improving the purity of the hydraulic oil. After the above filtering steps, the impurities in the hydraulic oil have been largely removed. At this time, the valve 39 on the oil drain pipe 38 can be rotated to allow the hydraulic oil filtered in the filter tank 1 to flow along the oil drain pipe 38 into the recovery chamber 34 in the oil tank 32 for recycling, which saves resources and reduces production costs. If the filter module 25 needs to be cleaned or replaced, the two hydraulic cylinders 295 can be started. The two hydraulic cylinders 295 will respectively work with the two rotating blocks 1 293, the two rotating blocks 294, the rectangular frame 29 and the L The L-shaped rods 291 cooperate with each other. Under the effect of this coordinated cooperation, the L-shaped rod 291 can drive the sealing cover 292 on it to flip to a suitable angle. After the sealing cover 292 is flipped, the filter module 25 can be pulled outward to be cleaned or replaced. Through the above-mentioned settings, the cumbersome procedures during the installation and disassembly of the filter can be effectively reduced, thereby improving the efficiency of the filter installation and saving time and labor costs.
