Description

Technical Field

[0001] This utility model relates to the field of hydraulic station technology, specifically to a hydraulic oil filter barrel. Background Technology

[0002] Hydraulic oil, as the working medium of a hydraulic power unit, circulates within the system. Impurities generated during operation need to be filtered and replaced regularly to ensure the cleanliness and efficient operation of the hydraulic system. Filtration requires draining the hydraulic oil for purification, which takes a long time. Frequent purification processes can affect the working efficiency of the hydraulic power unit. If impurities in the hydraulic oil are not removed in time, they can also cause wear and tear on the equipment, affecting its service life. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0017] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model. Furthermore, if terms such as "first" or "second" appear in the description of this utility model, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] As shown in the attached figure, this utility model includes a barrel body 1 and a cover body 2 that can be detachably installed on the top of the barrel body 1. An oil inlet pipe 3 is provided on the side wall of the barrel body 1, and an oil outlet pipe 4 is provided at the bottom of the barrel body 1. A first filter cylinder 5 and a second filter cylinder 6 are coaxially sleeved inside the barrel body 1 from the outside to the inside. The filter hole diameter of the first filter cylinder 5 is larger than that of the second filter cylinder 6. A set of magnetic suction plates 7 are arranged in a ring on the outer wall of both the first filter cylinder 5 and the second filter cylinder 6.

[0020] Hydraulic oil enters through the inlet pipe 3 and passes through the first filter cartridge 5 and the second filter cartridge 6 for filtration before being discharged through the outlet pipe 4. The filter hole diameter of the first filter cartridge 5 is larger than that of the second filter cartridge 6, which can filter particles of different sizes in layers. The magnetic suction plate 7 is used to magnetically attract the passing iron filings and debris to ensure the normal use of hydraulic oil.

[0021] Furthermore, the cover 2 is detachably mounted on the top of the barrel 1 via a set of screws, and a seal 8 is provided between the connecting surfaces of the cover 2 and the barrel 1. Both the cover 2 and the barrel 1 are provided with connecting flanges, and a seal mounting groove is provided on the connecting flange of the barrel 1, with the seal 8 located in the groove.

[0022] Furthermore, an annular guide plate 10 is coaxially provided at the bottom of the cover 2. The annular guide plate 10 is located between the barrel 1 and the first filter cartridge 5, and the bottom height of the annular guide plate 10 is lower than the height of the oil inlet pipe 3. After the hydraulic oil enters from the oil inlet pipe 3, it is blocked by the annular guide plate 10 and will disperse along the annular guide plate 10 to both sides and enter the cavity between the first filter cartridge 5 and the barrel 1, thus preventing the hydraulic oil from directly washing onto the first filter cartridge 5.

[0023] Preferably, the first filter cartridge 5 and the second filter cartridge 6 have the same structure, both being cylindrical structures with a closed top and an open bottom. A sedimentation tank 12 is provided around the bottom outer side of both the first filter cartridge 5 and the second filter cartridge 6, and the magnetic suction plate 7 is located inside the sedimentation tank 12. The filtered impurities will settle in the sedimentation tank 12. During cleaning, the cover 2 is opened, and the first filter cartridge 5 and the second filter cartridge 6 are removed in sequence. This process effectively prevents sediment from falling into the container 1.

[0024] Furthermore, both the first filter cartridge 5 and the second filter cartridge 6 are provided with handles 13 at their tops.

[0025] Furthermore, both the first filter cartridge 5 and the second filter cartridge 6 have a set of slots arranged in a ring on their side walls, and the magnetic suction plate 7 is movably inserted into the slots. In this case, the magnetic suction plate 7 is movably covered with a plastic sleeve, and is inserted into the slot through the plastic sleeve. When cleaning the adsorbed metal impurities, the magnetic suction plate 7 can be directly pulled out from the plastic sleeve, and the metal impurities can be quickly removed from the plastic sleeve.

[0026] Furthermore, the sedimentation tank 12 of the first filter cartridge 5 is fitted to the inner wall of the barrel 1, and the sedimentation tank 12 of the second filter cartridge 6 is fitted to the inner wall of the first filter cartridge 5. That is, after the first filter cartridge 5 and the second filter cartridge 6 are installed, there is no gap between their sedimentation tank 12 and the barrel 1, so the filtered sediment will not directly settle into the barrel 1, and the sediment can be taken out when the first filter cartridge 5 and the second filter cartridge 6 are removed.
