Description

Technical Field

[0001] This utility model relates to the field of oil film removal technology, specifically to an oil filter machine for removing paint film. Background Technology

[0002] Oil filters are used in gas and steam turbines and compressors to remove dissolved and suspended soft contaminants, sludge, and other harmful substances from oil. This prevents turbine failures and costly oil changes caused by varnish problems. The initial formation of varnish, the so-called soft contaminant, is caused by hot spots in the system. Once formed, varnish adheres to bearings, valves, filters, etc., easily causing valve sticking, loss of control, and unit failure or start-up failure; filter blockage restricts oil flow, leading to increased oil temperature and wear; heat exchange failure causes oil temperature rise; sandpaper-like surfaces increase component wear; varnish formation on bearings restricts flow, increases wear and temperature; and frequent oil changes and system flushing are required. Existing technologies typically use electrostatic adsorption or ion exchange to remove varnish. However, when using electrostatic adsorption, other additives in the oil are easily adsorbed, reducing the quality and lifespan of the lubricating oil. Therefore, a varnish-removing oil filter is proposed to efficiently remove varnish, moisture, and mechanical particles from oil, effectively reducing varnish formation. Summary of the Invention

[0003] The purpose of this invention is to provide a paint film removal and oil filter to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a varnish removal oil filter, characterized by including a filter, a coalescing separator connected to the filter, an oil cooler connected to the coalescing separator to reduce the oil temperature so that the varnish film precipitates from the oil and becomes suspended, and a four-stage fine filter connected to the oil cooler to remove submicron-sized particulate impurities and varnish film; the filter is also connected to an oil pump.

[0005] Preferably, the filter includes a primary filter and a secondary filter connected to both ends of the oil pump, and a tertiary filter connected between the coalescing separator and the oil cooler.

[0006] Preferably, an oil discharge pump is connected between the coalescing separator and the tertiary filter.

[0007] Preferably, the coalescing separator is also connected to a drainage channel.

[0008] Preferably, an oil drain channel is also connected between the three-stage filter and the oil cooler.

[0009] The beneficial effects of this utility model are as follows: by using a filter to filter impurities in the oil, then passing the oil through a coalescing separator to coalesce and separate the water in the oil, the oil is cooled by an oil cooler to separate the varnish film from the oil, and the submicron-sized particulate impurities and varnish film in the oil are filtered by a four-stage fine filter to finally obtain clean, water-free lubricating oil for continued use. This can efficiently remove varnish film, water and mechanical particles from the oil, effectively reducing the formation of varnish film. Attached Figure Description

[0012] The paint film removal oil filter machine of this utility model will be further described below with reference to the accompanying drawings.

[0013] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0014] See appendix Figure 1 As shown in the figure, this embodiment of a varnish removal oil filter is characterized by including a filter, a coalescing separator 1 connected to the filter, an oil cooler 2 connected to the coalescing separator 1 to reduce the oil temperature and cause the varnish film to precipitate from the oil and become suspended, and a four-stage fine filter 3 connected to the oil cooler 2 to remove submicron-sized particulate impurities and varnish film; the filter is also connected to an oil pump 4; by using the filter to filter impurities in the oil, then the water in the oil is coalesced and separated by the coalescing separator 1, the oil is cooled by the oil cooler 2 to precipitate the varnish film from the oil, and the four-stage fine filter 3 filters out the submicron-sized particulate impurities and varnish film in the oil, finally obtaining clean, water-free lubricating oil for continued use, thereby efficiently removing varnish film, water and mechanical particles from the oil, effectively reducing the formation of varnish film.

[0015] See appendix Figure 1As shown, the filter pack is connected to a primary filter 5 and a secondary filter 501 at both ends of the oil pump 4, and a tertiary filter 502 between the coalescing separator 1 and the oil cooler 2; an oil discharge pump 6 is connected between the coalescing separator 1 and the tertiary filter 502; a drainage channel 101 is also connected to the coalescing separator 1; and an oil discharge channel 7 is also connected between the tertiary filter 502 and the oil cooler 2. By using the primary filter 5, the secondary filter 501, and the tertiary filter 502 to filter large particulate impurities and small impurities in the oil, the filtration effect of the oil is improved, and clean lubricating oil can be obtained for continued use.

[0016] In the working process of this utility model, the substandard lubricating oil first passes through the primary filter 5, which filters out large particulate impurities. Then, it passes through the oil pump 4 into the secondary filter 501, which filters out smaller impurities. The lubricating oil after this second filtration flows into the coalescing separator 1. In the coalescing separator 1, the coalescing filter element agglomerates tiny water droplets into larger droplets. Most of the agglomerated water droplets are separated from the oil by gravity and discharged through the drain channel 101. Then, it flows through the separation filter element. Due to the separation filter element's excellent oleophilic and hydrophobic properties, it performs pressure swing analysis on the oil, eliminating intermolecular forces. This further causes dissolved and free water in the oil to quickly break down the oil film and precipitate out. The dehydrated oil then flows through the drain pump 6 to the tertiary filter 502, which filters the oil again. The filtered oil continues to flow into the oil cooler 2, which cools the oil to approximately 20°C. As the oil temperature decreases... The thermal stability of the varnish film is worse than that of the oil, so it will precipitate out of the oil and become suspended. Then it passes through the fourth-stage fine filter 3, which filters out submicron-sized particulate impurities and the varnish film in the oil, finally obtaining clean, water-free lubricating oil that can be used again.

[0017] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
