Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pump station technology, specifically relating to a hydraulic oil filtration device for a hydraulic pump station. Background Technology

[0002] The hydraulic oil filtration device in a hydraulic pump station is a crucial component ensuring the normal operation of the hydraulic system; it acts like a "cleaning guardian" for the system. When hydraulic oil circulates within the pump station, it accumulates contaminants such as metal particles, dust, and moisture due to wear on internal components and the introduction of external impurities. If these contaminants are not removed promptly, they accelerate the wear of hydraulic components, leading to problems such as damaged seals and stuck valve cores, thus affecting the performance and lifespan of the pump station. The hydraulic oil filtration device precisely intercepts and filters out these contaminants, keeping the hydraulic oil clean, ensuring stable and efficient power output from the pump station, extending the overall lifespan of the hydraulic system, and reducing equipment failure rates and maintenance costs.

[0003] In the current operation and maintenance of hydraulic systems, existing hydraulic oil filtration devices exhibit numerous inconveniences in the critical operation of replacing the internal filter cartridge. When filter cartridge replacement is required, workers must rely on various external tools such as wrenches and screwdrivers to disassemble the device. This process is time-consuming, significantly impacting equipment downtime maintenance efficiency and potentially leading to production delays. Even more problematic is the risk of screws at the connection points accidentally falling off during disassembly. If they do, they may not only fall into the hydraulic oil, contaminating it, but could also become lodged in the complex internal structure of the device, causing equipment malfunctions and increasing repair difficulty and costs. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic oil filtration device for a hydraulic pump station, so as to solve the problem mentioned in the background art that the internal filter cartridge of the existing hydraulic oil filtration device is not easy to replace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic oil filtration device for a hydraulic pump station, comprising an outer cylinder with an open bottom and through holes evenly distributed in the lower middle area of ​​its surface; a bottom cylinder located directly below the outer cylinder; and a connecting assembly; the connecting assembly includes a locking member and a sliding part, wherein the sliding part is equidistantly formed on the inner wall of the bottom of the outer cylinder; the locking member is positioned above the sliding part, and one end of the locking member extends toward the inner side of the sliding part; a protrusion is provided at equal intervals at the top edge of the bottom cylinder, the protrusion being engaged in the sliding part and resisting the locking member by rotation; when the protrusion passes the locking member, without external force intervention, the protrusion will be limited by the locking member and will not detach from the sliding part; conversely, by applying a rotational force to the bottom cylinder, the bottom cylinder can be separated from the outer cylinder.

[0006] Preferably, the sliding part includes an arc groove, one end of which has an opening groove extending downwards, and a placement groove is formed above the other end of the arc groove. The locking member is disposed in the placement groove. During installation, the protrusion is inserted from the opening groove, and then the locking member is pushed open by rotation. The protrusion is then limited by the rebound of the locking member.

[0007] Preferably, the locking component includes a limiting block movably disposed in the placement groove. A spring is connected between the limiting block and the placement groove. The bottom ends of the limiting block are arc-shaped and have guide portions. The arc-shaped area of ​​the limiting block contacts the protrusion, thereby ensuring that the limiting block can be pushed open by the protrusion when the bottom cylinder is rotated. When the limiting block is pushed open, the spring is compressed. When the protrusion passes the limiting block, the spring rebounds, thereby limiting the protrusion.

[0008] Preferably, the width of the opening groove is equal to the width of the protrusion, and the inner height of the arc groove is greater than or equal to the height of the protrusion.

[0009] Preferably, a sealing ring and a rubber ring are sequentially fitted on the top of the bottom cylinder from top to bottom. The sealing ring is located below the protrusion. The sealing ring abuts against the bottom end face of the outer cylinder through the elasticity of the rubber ring, thereby sealing the gap of the opening groove and reducing or even preventing liquid from seeping out from here.

[0010] Preferably, the outer diameter of the top of the bottom cylinder is smaller than the outer diameter of its bottom, the outer diameter of the top of the bottom cylinder fits seamlessly with the inner diameter of the outer cylinder, and the height of the area where the bottom cylinder is inserted into the outer cylinder completely covers the placement groove. With the addition of a sealing ring, the arc groove, the opening groove, and the placement groove can be completely covered to achieve sealing.

[0011] Preferably, a connector is connected to the top of the outer cylinder, and a filter cartridge is placed inside the outer cylinder (not shown in the figure). The liquid entering through the connector passes through the filter cartridge before being discharged from the through hole on the outer cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the practical application and maintenance of hydraulic oil filtration devices, to solve the problem of low filter cartridge replacement efficiency, an innovative improvement was made to the outer cylinder structure of the device. The original one-piece outer cylinder was changed to a detachable structure. When replacing the filter cartridge, the operator does not need to use any external tools. They can simply operate manually according to the pre-designed disassembly method to disassemble the outer cylinder into several parts, thereby easily removing the old filter cartridge and installing the new one. This design greatly simplifies the filter cartridge replacement operation process, reduces unnecessary operation steps and time consumption, and enables the operator to complete the filter cartridge replacement work more quickly, effectively improving work efficiency and ensuring the normal operation of the hydraulic system.
