Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a filter device for cleaning hydraulic cylinders. Background Technology

[0002] Hydraulic cylinders are a type of pressure finishing process that utilizes the cold plasticity of metals at room temperature. A rolling tool applies pressure to the surface of the workpiece, causing the surface metal to plastically flow and fill the original residual low-recessed valleys, thereby reducing the surface roughness. Due to the plastic deformation of the rolled surface metal, the surface structure is cold-hardened and the grains are refined, forming a dense fibrous structure and a residual stress layer, which increases hardness and strength, thereby improving the wear resistance, corrosion resistance, and fit of the workpiece surface.

[0003] A cleaning device for hydraulic cylinders is disclosed in patent publication number CN207628855U. This patent includes a cleaning machine body with a cleaning tank inside. A mesh frame is provided on one side wall of the cleaning tank, and a U-shaped rod is vertically mounted on the top of the mesh frame. A support rod is vertically mounted on the side of the cleaning tank away from the mesh frame on the U-shaped rod cleaning machine body. A top plate is provided at the end of the support rod away from the cleaning machine body. Two sets of hydraulic cylinders are mounted on the top plate away from the support rod. Lifting rods are connected to the output ends of both sets of hydraulic cylinders, passing through the top plate. Support plates are vertically connected to the ends of the two sets of lifting rods away from the hydraulic cylinders. Rotating rods are rotatably connected at equal intervals on the side of the support plate near the cleaning tank. A spiral first cleaning plate is provided on the outer side of the rotating rod, and two sets of second cleaning plates are provided on the outer side of the first cleaning plate. The tops of the two sets of second cleaning plates are connected to the rotating rods via straight rods. A transmission gear is provided at the top of the rotating rod, and adjacent sets of transmission gears mesh and rotate together. A positioning frame installed at the bottom of the cleaning tank is located directly below the rotating rod to hold various small parts on the hydraulic cylinders. The parts are placed in the mesh frame, then into the positioning ring of the cylinder protective positioning frame, and cleaning agent is injected into the cleaning tank. The liquid level of the cleaning agent should cover the cylinder and the mesh frame. Then, the hydraulic cylinder is started, and the support plate is lowered through two sets of lifting rods. Then, the drive motor is started, and the drive gear rotates the driven gear through gear transmission. The driven gear drives the rotating rod, the first cleaning plate and the second cleaning plate to rotate and descend. The rotating rod rotates into the inside of the cylinder. The spiral first cleaning plate facilitates the discharge of the cleaning agent in the cylinder and facilitates the entry of the rotating rod into the cylinder. The first cleaning plate and the second cleaning plate use cleaning brushes to rotate and brush the inner and outer walls of the cylinder. This device has a simple structure and novel design. Small parts are not easily lost when cleaned individually. At the same time, it performs a rotating up and down washing of the inner and outer walls of the hydraulic cylinder, resulting in good cylinder cleaning effect and high cleaning efficiency. However, this patent still has the following problems:

[0004] The aforementioned cleaning device for hydraulic cylinders discharges a mixture of water and oil outside the device after cleaning the hydraulic cylinder parts. If the oil is not treated, it can easily affect the environment.

[0005] To address the above problems, a filtration device for cleaning hydraulic cylinders needs to be designed to overcome them. Utility Model Content
