Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, specifically to a refining filtration device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Currently, during the production of lubricating oil, some impurities left over from processing or from external sources often get mixed in. Therefore, lubricating oil usually needs to be filtered before packaging.

[0003] In this process, when lubricating oil passes through the fine filter, the flow rate is slow due to the lubricating oil's colloidal nature and the micron-level filtration precision of the fine filter. This increases the filtration time and reduces the filtration efficiency. Furthermore, although a coarse filtration system is installed upstream of the fine filter, the current coarse filtration system has low filtration precision. Large particles of impurities pass through the coarse filtration system and are then filtered by the fine filter, leading to excessively high frequency of fine filter replacement or maintenance and increased production costs. Therefore, this invention proposes a refining filtration device for lubricating oil production. Utility Model Content

[0020] Please see Figures 1-2 In this embodiment, a refining filtration device for lubricating oil production is provided, including a pressure oil tank 1. An inlet pipe 2 is fixedly installed at the upper end of the pressure oil tank 1, and a fine filter 3 is installed at the upper end of the inlet pipe 2. An oil inlet pipe 4 connected to the fine filter 3 is installed at the upper end of the fine filter 3, and a second switch valve 40 is provided on the oil inlet pipe 4. An oil outlet tee pipe 6 is installed at the bottom of the pressure oil tank 1. A vacuum machine 7 is installed at one end of the bottom of the oil outlet tee pipe 6, and an oil drain pipe 8 is fixedly installed at the other end of the bottom of the oil outlet tee pipe 6. A fourth switch valve 61 and a fifth switch valve 62 are respectively provided on both sides of the bottom of the oil outlet tee pipe 6. By setting the fine filter 3 at the front end of the pressure oil tank 1 and setting the oil outlet tee pipe 6, the fourth switch valve 61, the fifth switch valve 62, the vacuum machine 7, and the oil drain pipe 8 at the oil outlet end of the pressure oil tank 1, the pressure oil tank 1 can be evacuated to a vacuum state in advance. Therefore, when the lubricating oil passes through the oil inlet pipe 4, it can quickly pass through the fine filter 3 under negative pressure, thereby improving the filtration efficiency.

[0021] In this embodiment, an air pump 5 is fixedly installed on one side of the top of the pressure oil tank 1, and the air pump 5 is connected to the pressure oil tank 1 through an air outlet pipe. A third switch valve 50 is installed on the air outlet pipe, and a first switch valve 20 is installed on the inlet pipe 2. In addition, in order to further improve the oil output efficiency after filtration, by adding an air pump 5 to the pressure oil tank 1, the pressure inside the pressure oil tank 1 can be increased by the air pump 5 when the negative pressure inside the pressure oil tank 1 is too low, and the first switch valve 20 can be closed. This can effectively improve the oil output efficiency of the filtered lubricating oil and speed up the production progress.

[0022] In this embodiment, the fine filter 3 is provided with a precision filter element 30 inside, and a connecting pipe 10 is provided at the top of the fine filter 3. The connecting pipe 10 is connected to the oil inlet pipe 4, and the lower end of the connecting pipe 10 is connected to the filter medium inlet of the precision filter element 30. Specifically, the filtration accuracy of the precision filter element 30 is 0.3-0.5μm. It can be a precision metal sintered filter element purchased from Gu'an County Fengkai Filter Material Co., Ltd., which has good corrosion resistance. There are multiple precision filter elements 30 and multiple connecting pipes 10, and the multiple precision filter elements 30 and multiple connecting pipes 10 correspond one-to-one.

[0023] In this embodiment, a coarse filter box 9 is installed between the connecting pipe 10 and the oil inlet pipe 4, and multiple coarse filter plates 90 are provided inside the coarse filter box 9. The coarse filter plates 90 are microporous filter plates, and the filtration accuracy of the coarse filter plates 90 is 5μm. By adding a coarse filter box 9 at the front end of the fine filter 3, and adding microporous filter plates with a filtration accuracy of 5μm inside the coarse filter box 9, large particulate impurities that were not filtered out during the front-end coarse filtration system can be pre-screened and removed. This avoids large particulate impurities directly passing through the fine filter 3, which would reduce the service life of the fine filter 3, thereby effectively reducing costs and preventing… To prevent the fine filter 3 from becoming clogged and affecting the filtration progress, first close the fifth switch valve 62 and the third switch valve 50, then open the fourth switch valve 61, the first switch valve 20, and the second switch valve 40. Start the vacuum machine 7 to create a vacuum negative pressure in the pressure oil tank 1 and the fine filter 3. Then open the second switch valve 40 and close the fourth switch valve 61, allowing the lubricating oil to enter the coarse filter box 9 and the fine filter 3 through the oil inlet pipe 4 and flow into the pressure oil tank 1. When rapid oil drainage is required, start the air pump 5, open the third switch valve 50, close the first switch valve 20, and open the fifth switch valve 62 to complete the rapid oil drainage.
