[0002] Detecting mechanical impurities in lubricating oil is a key indicator of lubricant quality. The presence of mechanical impurities can affect the rheological properties, thermal stability, and lubrication performance of the lubricant, potentially causing increased wear and even damage to mechanical equipment. By measuring the amount of mechanical impurities, adjustments to lubricant additives can be made.
[0003] The detection of mechanical impurities in lubricating oil is typically performed in the laboratory. During this process, the laboratory must filter a heated sample containing a mixture of lubricating oil and solvent oil (primarily toluene) vapor (hereinafter referred to as oil mist), reaching temperatures of 70-80°C.

The drawn air flowing through the heated sample carries a certain amount of high-temperature vapor from lubricating oil and solvent oil, forming an oil mist. This oil mist, drawn directly into the vacuum pump without separation, accumulates and condenses over time, corroding vacuum pump components and clogging the filtration line. This can lead to poor vacuum pump performance or even damage. Furthermore, it pollutes the ambient air and poses a health and safety hazard to testers.

[0029] The utility model discloses an adsorption tower purification device, see Figure 1The adsorption tower purification device includes a base 1, a sleeve 2, a tower cover 3, and a replaceable adsorption unit 4. The base 1 is provided with an air intake structure 5, and the tower cover 3 is provided with an exhaust structure 6. The sleeve 2 is removably and hermetically connected to the base 1, and the tower cover 3 is removably and hermetically connected to the sleeve 2. The base 1, sleeve 2, and tower cover 3 enclose a purification chamber. One or more replaceable adsorption units 4 are provided in the purification chamber.
[0030] When the exhaust structure 6 is connected to the inlet of the vacuum pump and the vacuum pump is started, the hot liquid petroleum product vapor enters the purification chamber from the air intake structure 5 and flows upward through the replaceable adsorption unit 4. The replaceable adsorption unit 4 adsorbs the liquid petroleum product vapor, and the gas purified by adsorption flows from the exhaust structure 6 to the vacuum pump, thereby reducing the hot liquid petroleum product vapor from being sucked into the vacuum pump during the filtration process, avoiding environmental pollution, being beneficial to occupational health protection, reducing the failure rate of the vacuum pump, and improving equipment efficiency.
[0031] For details, see Figure 1 , the base 1 is a hollow cavity structure.
[0032] In this embodiment, the base 1 simultaneously serves as an air intake, a temporary condensate collection unit, and a support for the rest of the tower body. It should be understood that after use, the condensate temporarily stored in the inner cavity of the base 1 can be poured out by disassembling the separation sleeve 2 and the base 1.
[0033] For details, see Figure 1 The tower cover 3 has a hemispherical inner wall surface 31, and the exhaust structure 6 is an air outlet, which is arranged at the top of the tower cover 3. The purified air is sucked into the vacuum pump from the air outlet.
[0034] In this embodiment, the tower cover 3 is provided with a hemispherical inner wall surface 31 , so that the hemispherical inner wall surface 31 acts as a gas buffer to reduce the impact force of instantaneous airflow on the tower cover.
[0035] For details, see Figure 1 The air intake structure 5 is an air intake pipe, one end of which is located outside the base 1 and the other end extends into the middle of the inner cavity of the base 1.
[0036] In this embodiment, the other end of the air inlet pipe is extended into the middle of the inner cavity of the base 1, so that the gas entering the inner cavity of the base 1 can be more evenly distributed.
[0037] Specifically, all replaceable adsorption units 4 are detachably installed in the sleeve 2 by means of snap fasteners or the like, so that the replaceable adsorption units 4 can be easily replaced.
[0038] For more details, see Figure 1 , the replaceable adsorption units 4 are stacked from top to bottom in the sleeve 2. The number of replaceable adsorption units 4 can be set according to actual needs.
[0039] The multiple replaceable adsorption units 4 of this embodiment adopt a stacking structure, which is convenient for disassembly, cleaning, elution and reuse.
[0040] Specifically, see Figure 1 The device includes a support ring 7 fixedly connected to the bottom end of the inner wall of the sleeve 2. The stacked replaceable adsorption units 4 are supported on the support ring 7. In a specific embodiment, the device also includes an annular sealing gasket 8. An annular sealing gasket 8 is provided between two adjacent replaceable adsorption units 4 and between the bottom replaceable adsorption unit 4 and the support ring 7 to enhance the suction effect of the vacuum pump.
[0041] In order to facilitate replacement, a gap is provided between the replaceable adsorption unit 4 and the inner wall of the sleeve 2 .
[0042] For details, see Figure 1 The replaceable adsorption unit 4 includes a cylindrical side wall body 41, an upper mesh structure 42, a lower mesh structure 43 and a bottom mesh structure 44 located below the lower mesh structure 43. The bottom mesh structure 44 is connected to the bottom end of the cylindrical side wall body 41 and a spoiler 45 is installed on its upper end. The upper mesh structure 42, the cylindrical side wall body 41 and the lower mesh structure 43 enclose a filling bin 46. The lower mesh structure 43, the inner wall surface of the cylindrical side wall body 41 and the bottom mesh structure 44 enclose a gas uniform distribution chamber 47. In a specific embodiment, the mesh of the bottom mesh structure 44 is square or diamond-shaped, and the mesh diameter is about 2 mm. The cylindrical side wall body 41 is made of stainless steel. The height of the filling bin 46 is about 5 cm. The mesh of the upper mesh structure 42 and the mesh of the lower mesh structure 43 can be square or diamond-shaped, and the mesh diameter is about 0.5 mm.
[0043] Spoiler 45 distributes the rising airflow as evenly as possible, facilitating the sufficient absorption of oil mist by the filler in rear-end filler hopper 46. Gas distribution chamber 47 buffers and mixes the airflow, providing as much free space as possible for airflow. The filler in filler hopper 46 absorbs oil mist from the air after the primary purification process.
[0044] The spoiler 45 can adopt an existing design. For example, the spoiler 45 is a group of hard baffles at an angle of 45° to the horizontal direction. The hard baffle group is welded to the bottom mesh structure 44 of the replaceable adsorption unit 4. The spoiler 45 can effectively redistribute the airflow to ensure that the passing airflow is fully disturbed.
[0045] The filling chamber 46 can be completely filled with the adsorbent or partially filled with the indicator so as to observe whether the adsorbent is effective.
[0046] More specifically, see Figures 1 to 3The replaceable adsorption unit 4 includes a partitioning screen 48 for separating the filling chamber 46 into an indicator chamber 461 and an adsorbent chamber 462. In a specific embodiment, the partitioning screen 48 is vertically embedded in the filling chamber 46, 1 cm from its edge, dividing the filling chamber 46 into two chambers. The smaller chamber serves as the indicator chamber 461, which is filled with the indicator, and the larger chamber serves as the adsorbent chamber 462, which is filled with the adsorbent. The partitioning screen 48 can be made of the same material as the upper and lower screen structures.
[0047] In a specific embodiment, the adsorbent can be a resin adsorbent with high oil absorption performance. A reagent kit of suitable size and shape is placed in the indicator compartment. The kit box is made of transparent glass, with one side facing the adsorbent compartment open and the other sides closed. The box is filled with an absorbent cotton carrier that has been thoroughly soaked in a mixed solution including potassium hydroxide, ethanol, and cresol red.
[0048] In this embodiment, if the indicator changes from purple to yellow, it means that the adsorbent has failed and the replaceable adsorption unit 4 needs to be replaced.
[0049] Specifically, see Figure 1 The sleeve 2 is equipped with an outer observation window 21 , and the cylindrical side wall 41 of the replaceable adsorption unit 4 is equipped with an inner observation window 411 . Both the outer observation window 21 and the inner observation window 411 are arranged corresponding to the indicator chamber 461 of the replaceable adsorption unit 4 .
[0050] In this embodiment, an external observation window 21 is provided to facilitate the user to directly observe the color of the indicator from the outside, and to judge whether the adsorbent is invalid by the color change of the indicator, thereby ensuring timely replacement of the replaceable adsorption unit 4.
[0051] For details, see Figure 1 The device includes a sealing ring. The sleeve 2 is a cylindrical body with an upper open end and a lower open end. The tower cover 3 is connected to the upper open end of the sleeve 2 by a first bolt fastener, and the lower open end of the sleeve 2 is connected to the base 1 by a second bolt fastener. Sealing rings are respectively provided between the tower cover 3 and the upper open end of the sleeve 2, and between the base 1 and the lower open end of the sleeve 2 to ensure that the system is airtight when the vacuum pump is operating.
[0052] Specifically, the upper and lower open ends of the sleeve 2 are each provided with an annular outer edge, which is arranged at a 90° angle to the sleeve 2 wall. The width of the annular outer edge is not less than 2 cm. Bolt holes for corresponding bolt fasteners are provided in the annular outer edge. The annular outer edge, bolt holes, and corresponding bolt fasteners are not shown in the figure.
[0053] The second aspect of the present invention provides a purification system, which includes the above-mentioned adsorption tower purification device and a vacuum pump, the exhaust structure 6 of the adsorption tower purification device is connected to the inlet of the vacuum pump, and the air intake structure 5 of the adsorption tower purification device is connected to an external filtration device.
[0054] The filtration device can be a filtration bottle device, which belongs to the existing technology, so its specific structure and working principle are not described in detail in this application.
[0055] Furthermore, in order to improve the purification effect, a condensation absorption purification device can be provided upstream of the adsorption tower purification device and downstream of the suction filtration device.
