Description

Technical Field

[0001] The utility model relates to the technical field of gear oil filtering, in particular to a multi-stage filtering device for gear oil processing. Background Art

[0002] Gear oil primarily refers to the lubricant for transmissions and rear axles. It differs from engine oil in terms of operating conditions, composition, and performance. Gear oil primarily lubricates gears and bearings, prevents wear and corrosion, and dissipates heat from gears. Gear oil is a crucial lubricant formulated primarily with petroleum-based or synthetic lubricants, supplemented with extreme pressure anti-wear agents and oiliness enhancers. It is used in various gear transmissions to prevent tooth wear, galling, and sintering, extending their service life and improving power transmission efficiency.

[0003] During the gear oil processing and production process, the gear oil will contain some particles. In order to make the mechanical equipment run better and prevent the wear of the mechanical equipment, the processed gear oil needs to be filtered. After use, the existing filtering device is not convenient for cleaning the filter residue on the filter screen, which can easily cause clogging of the filter screen and affect the next use.

[0004] In response to the above problems, we propose a multi-stage filtration device for gear oil processing. Utility Model Content

During the left and right movement, the push plate will vibrate the coarse filter through the spring sheet, so that the larger particles of residue on the coarse filter will slide onto the dirt-carrying plate. At the same time, the vertical rod will drive the fixed plate and the cleaning plate to move left and right, pushing the residue on the fine filter to the left and right sides. Then, the filter residue on the dirt-carrying plate and the fine filter can be cleaned through the discharge port to avoid clogging the filter and thus not affecting the next use.
