Description

Technical Field

[0001] This utility model relates to the field of oil skimmers, and in particular to an easy-to-maintain oil skimmer. Background Technology

[0002] Oil skimmers are crucial equipment in industrial manufacturing processes used to remove floating oil (hydraulic oil, rust-preventive oil, etc.) from the surface of water-based process media such as cutting fluids and cleaning fluids, which is essential for extending the life of these media. Traditional oil skimmers include belt skimmers (steel belt type, leather belt type, canvas or nylon woven type), disc skimmers, tubular skimmers, and spiral skimmers. However, traditional oil skimmers have significant drawbacks:

[0003] 1) Inconvenient replacement of wear parts: Wear parts such as oil scraper / ring need to be replaced regularly, but the existing design makes the replacement process cumbersome and affects maintenance efficiency;

[0004] 2) Floating debris causes blockages and maintenance difficulties: When precision machining low-density materials such as aluminum parts, aluminum-magnesium alloys, and titanium (e.g., in the 3C and aluminum die-casting industries), large-surface-area, thin-thickness debris is easily generated. Some of this debris enters the cutting fluid. Due to its light weight, large surface area, and high surface tension, it easily floats, especially when there is floating oil on the fluid surface. Traditional oil skimmers, when adsorbing floating oil, bring these floating debris into the equipment. Although floating oil has viscosity, it is fluid, while solid debris is not fluid. This debris accumulates continuously inside the equipment (such as in oil passages and oil collection chambers), eventually causing blockages and severely weakening the oil skimming function and working efficiency.

[0005] Once a blockage occurs, cleaning and maintaining existing skimmers becomes extremely inconvenient. Maintenance personnel typically need to disassemble multiple fasteners (such as screws), open the equipment cover to access the interior for cleaning, and then reassemble it. This process is not only complex and time-consuming, significantly reducing maintenance efficiency, but also greatly increasing labor intensity. Traditional structural designs have not fully considered this special blockage scenario caused by lightweight floating debris and the need for quick and convenient maintenance. Utility Model Content

[0006] This application addresses the shortcomings of the prior art by providing an easy-to-maintain oil skimmer. It replaces the traditional screw locking with hinges and magnetic fixation. During maintenance, only the top cover needs to be lifted to expose the internal oil collection chamber, improving the efficiency of cleaning debris or replacing the oil scraper by more than 50%. The gasket ensures that the top cover will not generate noise due to on-site vibration when closed, while also reducing wear.

[0007] The technical solution adopted in this utility model is as follows:

[0008] An easy-to-maintain oil skimmer includes an oil skimmer housing, a rotating shaft rotatably arranged at the center of the housing, an oil suction plate rotatably arranged on the shaft, oil scraping strips symmetrically arranged on both sides of the oil suction plate, a drive assembly arranged on the outer side of the housing, the drive assembly being connected to the rotating shaft, an oil collection box arranged below the discharge end of the housing, and a disassembly assembly arranged at the discharge end of the housing.

[0009] Furthermore, the disassembly assembly includes an upper cover plate for sealing the space above the discharge end of the skimmer housing. The rear end of the upper cover plate is rotatably connected to the adjacent housing surface via a hinge, and magnetic strips are provided on both sides of the front end of the upper cover plate.

[0010] Furthermore, a pad is provided at the end of the magnetic strip, and the pad is flush with the edge of the upper cover plate.

[0011] Furthermore, a viewing glass is provided at the center of the upper cover plate.

[0012] Furthermore, the drive assembly includes a motor housing fixed to one side of the skimmer housing, and a servo motor is disposed inside the motor housing. The servo motor is connected to the rotating shaft via a key to transmit torque.

[0013] Furthermore, a control box is fixedly installed on the rear surface of the oil collection box, and the control box is signal-connected to the drive assembly.

[0014] The advantages of this utility model over the prior art are as follows:

[0015] 1) Quick opening and closing for maintenance: Hinges and magnetic fastening replace traditional screws, allowing for easy maintenance by simply lifting the top cover to expose the internal oil collection chamber, improving cleaning efficiency by more than 50% or replacing the oil scraper; the gasket prevents the top cover from making noise due to vibrations when closed, while also reducing wear.

[0016] 2) Anti-clogging design: The viewing glass allows for real-time observation of debris accumulation, enabling timely prevention of clogging;

[0017] 3) Modular structure: The drive components and oil collection box are designed separately to prevent oil from seeping into the motor and to ensure that they do not interfere with each other during maintenance. Attached Figure Description

[0025] like Figures 1 to 4 As shown, this utility model includes an oil skimmer housing 1, with a rotating shaft 2 rotatably arranged at the center of the oil skimmer housing 1, an oil suction plate 3 rotatably arranged on the rotating shaft 2, and oil scraping strips 8 symmetrically arranged on both sides of the oil suction plate 3. A drive assembly 4 is also arranged on the outer side of the oil skimmer housing 1, and the drive assembly 4 is connected to the rotating shaft 2 for transmission. An oil collection box 5 is arranged below the discharge end of the oil skimmer housing 1, and a disassembly assembly 6 is arranged at the discharge end of the oil skimmer housing 1.

[0026] In one embodiment of this utility model, the disassembly assembly 6 includes an upper cover plate 61 for sealing the space above the discharge end of the oil skimmer housing 1. The rear end of the upper cover plate 61 is rotatably connected to the adjacent housing surface via a hinge 62, and magnetic strips 63 are provided on both sides of the front end of the upper cover plate 61.

[0030] In one embodiment of this utility model, a control box 7 is also fixedly provided on the rear surface of the oil collection box 5, and the control box 7 is signal connected to the drive component 4.

[0031] The specific structure and working principle of this utility model are as follows:

[0032] like Figures 1-4 As shown, this embodiment provides an easy-to-maintain oil skimmer, which mainly includes an oil skimmer housing 1, a rotating shaft 2, an oil suction plate 3, a drive assembly 4, an oil collection box 5, and a disassembly assembly 6.

[0033] The outer casing 1 of the oil skimmer is a stainless steel sealed box with a process medium inlet (not shown) at the bottom and a discharge end at the front. The rotating shaft 2 is coaxially mounted on the drive end of the servo motor 42 via a key connection, and a disc-shaped oil suction plate 3 (preferably made of an oleophilic and hydrophobic polymer material) is coaxially fixed on the rotating shaft 2.

[0034] The drive assembly 4 is located on the right side of the housing, including an aluminum alloy motor housing 41, and a servo motor 42 is installed inside the housing; the output shaft of the servo motor 42 is connected to the right end of the rotating shaft 2 via a flat key to transmit torque and realize the uniform rotation of the oil suction plate 3.

[0035] The disassembly assembly 6 is located at the discharge end and includes an upper cover plate 61, the size of which covers the entire discharge end opening. Its rear end is hinged to the top surface of the outer casing via a stainless steel hinge 62 to achieve opening and closing.
