Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thin oil lubrication technology for bar and wire rods, and specifically relates to a thin oil filtration device for bar and wire rods. Background Technology
[0002] Thin oil for bar milling lines is a type of lubricant used to lubricate bar milling and production equipment. During operation, an oil pump draws thin oil from the oil tank, which is then filtered to remove impurities. The thin oil, under pressure and at a certain flow rate, is then transported through pipelines to various lubrication points on the bar mill line, such as bearings in the rolling mill, gearboxes, and conveyor rollers. The thin oil forms an oil film at these lubrication points, reducing friction, decreasing wear, cooling, and flushing away impurities, thus ensuring the normal operation of the equipment. Afterward, the thin oil, carrying heat and wear debris, flows back to the oil tank, where it is cooled and filtered before being recycled again.
[0003] To ensure the quality of the thin oil, the filter element in the filtration device needs to be replaced frequently. The current method for replacing the filter element is to close the butterfly valve before the inlet pump, open the filter cartridge cover and drain port, allowing the oil inside the filter cartridge to flow out under gravity. Then, the pressure plate above the filter element is opened to remove and replace the filter element. Each time the filter element is replaced, the oil needs to be drained from the filter cartridge by its own gravity, resulting in a lengthy draining process that wastes a lot of manpower. Furthermore, the large amount of oil drained inevitably pollutes the environment. Utility Model Content
