Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil storage, in particular to a lubricating oil purification, storage and refueling system. Background Art

[0002] After the lubricating oil barrel is opened, air will enter the barrel, and as time goes by, the lubricating oil in the barrel will gradually absorb moisture in the air, causing the water content of the lubricating oil to increase, affecting the oil quality of the lubricating oil.

[0003] Therefore, most of the current methods use oil purifiers to purify, store, and output lubricating oil. Specifically, the lubricating oil in the oil barrel is first transported to the oil purifier tank, and the water in the lubricating oil is removed by purification equipment to keep the water content of the lubricating oil within the specified range. The qualified lubricating oil is then input into the oil storage barrel, and low-pressure nitrogen is introduced into the oil storage barrel. When the lubricating oil is needed, the lubricating oil is output through the refueling gun; and as the lubricating oil in the oil storage barrel is used, the lubricating oil can be purified and replenished through the oil purifier tank. However, the above method has the following disadvantages:

[0004] 1. Although there is low-pressure nitrogen in the oil storage barrel to maintain pressure (to prevent external moisture from entering the oil storage barrel), the low-pressure nitrogen itself also contains a small amount of moisture. During long-term use, the moisture in the low-pressure nitrogen will gradually enter the lubricating oil, thereby causing the lubricating oil to deteriorate in quality.

[0005] 2. The clean oil barrel and the oil storage barrel are independent of each other, which not only occupies a large area but also has a low utilization rate of the equipment. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a lubricating oil purification, storage and refueling system.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A lubricating oil purification, storage and refueling system comprises an oil barrel and an oil tank, wherein the oil tank and the oil barrel are connected via an oil inlet pipe, a nitrogen delivery pipe and a vacuum pipe are connected to the upper part of the oil tank, the vacuum pipe is connected to a vacuum pump, a circulation pipe is arranged on the oil tank, one end of the circulation pipe is connected to the bottom of the oil tank, the other end of the circulation pipe is connected to the top of the oil tank and connected to an atomizer, and the oil tank is connected to an oil gun via an oil delivery pipe.

[0009] Preferably, a partition cavity extending inward is provided at the lower portion of the oil tank, a heating rod is installed in the partition cavity, and thermal conductive grease is filled between the partition cavity and the heating rod.

[0010] Preferably, a temperature sensor is installed at the lower part of the oil tank.

[0011] Preferably, a moisture sensor, a circulation pump, a second filter, and an atomizer are sequentially arranged on the circulation pipe.

[0012] Preferably, the oil pipeline is provided with valve three, an oil pump, a flow meter and an oil gun in sequence.

[0013] Preferably, a filter 1 is provided on the oil inlet pipe between the oil barrel and the oil tank.

[0014] Preferably, a valve 1 is provided on the nitrogen delivery pipe.

[0015] Preferably, a second valve is provided on the vacuum pipe between the oil tank and the vacuum pump.

[0016] Preferably, there are multiple oil tanks.

[0017] The beneficial effects of the utility model are:

[0018] 1. The lubricating oil in the oil barrel is extracted into the oil tank by using the negative pressure of the vacuum pump, and then the lubricating oil at the bottom of the oil tank is circulated to the atomizer at the top by using the circulation pipe. The lubricating oil is sprayed into the oil tank by the atomizer, and the water in the atomized lubricating oil will be vaporized under the vacuum pump, and then pumped away by the vacuum pump, while the lubricating oil will not be vaporized under vacuum, so it will be stored in the oil tank. The water in the lubricating oil is separated by vacuum, which improves the oil quality of the lubricating oil;

[0019] 2. After the purification of the lubricating oil is completed, low-pressure nitrogen is introduced into the oil tank to prevent external moisture from entering the oil barrel, thereby ensuring the storage quality of the lubricating oil. The lubricating oil is not replenished during the use of the lubricating oil. After the lubricating oil in the oil tank is completely used up, the lubricating oil needs to be refilled, purified, and stored to realize the recycling of the oil tank. Compared with the existing storage method of using the oil tank for a long time, the contact time between the lubricating oil in the oil tank of the present application and the nitrogen is short, and the moisture in the nitrogen is not easy to enter the lubricating oil, which is not easy to affect the quality of the lubricating oil;

[0020] 3. By integrating the existing clean oil tank and oil storage tank into one oil tank, the occupied area is reduced and the utilization rate of the oil tank is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0027] Embodiment 1:

[0028] like Figure 1-2 As shown, a lubricating oil purification, storage and refueling system comprises an oil barrel 1 and an oil tank 2. The oil barrel 1 stores lubricating oil. The oil tank 2 is connected to the oil barrel 1 through an oil inlet pipe 21. A filter 211 is arranged on the oil inlet pipe 21 between the oil barrel 1 and the oil tank 2. The oil inlet pipe 21 is connected to the upper part of the oil barrel 1.

[0029] The upper part of the oil tank 2 is connected with a nitrogen delivery pipe 22 and a vacuum pipe 23, and the vacuum pipe 23 is connected with a vacuum pump 3. A valve 231 is provided on the vacuum pipe 23 between the oil tank 2 and the vacuum pump 3, and the connection or closing control between the oil tank 2 and the vacuum pump 3 is realized by switching the valve 231.

[0030] When the vacuum pump 3 is working, negative pressure can be formed in the oil tank 2, and then the lubricating oil in the oil barrel 1 is drawn into the oil tank 2 through the oil inlet pipe 21, and the height of the lubricating oil drawn into the oil tank 2 does not exceed the height of the oil inlet pipe 21. At the same time, during the process of the lubricating oil being drawn from the oil inlet pipe 21, the impurities in the lubricating oil are initially filtered through the filter 211.

[0031] After the extraction of the lubricating oil in the oil tank 2 is completed, the oil inlet pipe 21 is closed by a valve to avoid interference with the subsequent vacuum separation and water removal operations and the operation of outputting the lubricating oil to the outside.

[0032] The oil tank 2 is provided with a circulation pipe 24, one end of which is connected to the bottom of the oil tank 2, and the other end of which is connected to the top of the oil tank 2 and connected to an atomizer 244. The atomizer 244 plays a role similar to an atomizing nozzle and can spray the lubricating oil in atomized form. The circulation pipe 24 draws the lubricating oil from the bottom of the oil tank 2, and atomizes the lubricating oil through the atomizer 244 located at the top of the oil tank 2 and sprays it back into the oil tank 2, so as to circulate and transport the lubricating oil.

[0033] Specifically, during the circulation and transportation of the lubricating oil, the vacuum pump 3 works, that is, the vacuum pump 3 draws a vacuum in the oil tank 2, and sprays atomized lubricating oil into the oil tank 2 through the atomizer 244. The water in the lubricating oil will be vaporized under vacuum and then be sucked away by the vacuum pump 3, while the lubricating oil will not be vaporized under vacuum, and the atomized lubricating oil will re-gather and be stored in the oil tank 2, and then the water in the lubricating oil will be removed by vacuum separation to reduce the water content in the lubricating oil and improve the oil quality of the lubricating oil.

[0034] Furthermore, the circulation pipe 24 is provided with a moisture sensor 241, a circulation pump 242, a second filter 243, and an atomizer 244 in sequence. The circulation pump 242 provides a conveying power for the circulation pipe 24 to circulate the lubricating oil. The second filter 243 is used to filter the lubricating oil circulating on the circulation pipe 24 to filter the impurities in the circulating lubricating oil more finely. Specifically, the second filter 243 can filter out impurities with a particle size of 3 to 10 microns or more to improve the quality of the lubricating oil.

[0035] The moisture sensor 241 is used to detect the water content of the lubricating oil transported in the circulation pipe 24. When the moisture sensor 241 detects that the moisture content of the lubricating oil does not meet the regulations, the water removal and separation cycle can be continued until the moisture sensor 241 detects that the moisture content of the lubricating oil meets the regulations.

[0036] In order to improve the efficiency of removing water from the lubricating oil, a partition chamber 25 extending inward is provided at the lower part of the oil tank 2. The partition chamber 25 extends into the lubricating oil stored in the oil tank 2. The partition chamber 25 can be formed by a plurality of partitions. The partitions separate the interior of the oil tank 2 and the partition chamber 25. The material of the partition is the same as that of the oil tank 2. A heating rod 4 is installed in the partition chamber 25. The heating rod 4 can heat the lubricating oil to 50°C to 60°C. By heating the lubricating oil, the water in the lubricating oil can be more easily vaporized and separated.

[0037] Furthermore, thermal grease 251 is filled between the partition cavity 25 and the heating rod 4. The thermal grease 251 may be silicone grease or silicone oil. The thermal grease 251 cooperates with the partition cavity 25, and the heating rod 4 is used to indirectly heat the lubricating oil to prevent the heating rod 4 from directly contacting and heating the lubricating oil and affecting the quality of the lubricating oil.

[0038] The oil tank 2 and the heating rod 4 are separated by the partition chamber 25. When the heating rod 4 needs to be replaced, the oil tank 2 does not need to be emptied, and the heating rod 4 can be directly replaced, making the maintenance operation more convenient.

[0039] A temperature sensor 5 is installed at the lower part of the oil tank 2. The temperature sensor 5 is used to detect the temperature of the lubricating oil to prevent the heating rod 4 from heating the lubricating oil too high and affecting the quality of the lubricating oil.

[0040] The nitrogen delivery pipe 22 is provided with a valve 221, through which the opening or closing of the nitrogen delivery pipe 22 can be controlled. When the dehydration operation of the lubricating oil in the oil tank 2 is completed, low-pressure nitrogen is introduced into the oil tank 2 through the nitrogen delivery pipe 22 to maintain the pressure, so as to prevent external moisture from entering the oil barrel 2 and ensure the storage quality of the lubricating oil.

[0041] The oil tank 2 is connected to the oil gun 6 via an oil pipe 26, one end of the oil pipe 26 is connected to the oil gun 6, and the other end of the oil pipe 26 is connected to the circulation pipe 24 between the moisture sensor 241 and the circulation pump 242. The lubricating oil stored in the oil tank 2 can be output to the outside through the oil gun 6, and in the process of the oil gun 6 outputting the lubricating oil to the outside, the moisture sensor 241 can be used to detect in real time whether the water content of the output lubricating oil meets the regulations, that is, whether the output lubricating oil is qualified.

[0042] If the quality of the lubricating oil tested is unqualified, vacuum separation and water removal operation can be performed again until the quality of the lubricating oil meets the requirements.

[0043] The oil pipeline 26 is provided with valve three 261, oil pump 262, flow meter 263 and oil gun 6 in sequence. Valve three 261 can be used to open or close the oil pipeline 26. When the vacuum separation and water removal operation is performed, valve three 261 is closed. When the lubricating oil needs to be output to the outside through the oil gun 6, valve three 261 is opened, and the oil pump 262 is activated to output the lubricating oil to the outside. At the same time, the output lubricating oil is measured by the flow meter 263.

[0044] In this embodiment, when the lubricating oil is transported outward for use, the lubricating oil is not replenished in the oil tank 2. After the lubricating oil in the oil tank 2 is completely used up, the oil tank 2 needs to be cleaned, and then the lubricating oil is re-injected, purified, and stored to achieve the recycling of the oil tank 2. That is, after the lubricating oil in the oil tank 2 is used up, new lubricating oil and low-pressure nitrogen are re-injected, and the contact time between the lubricating oil and the nitrogen is one cycle when the lubricating oil in the oil tank 2 is used up.

[0045] Furthermore, compared with the existing storage method of using oil storage tanks for a long time, the contact time between the lubricating oil in the oil tank 2 of this embodiment and the nitrogen is short (the lubricating oil in the existing oil storage tank, with continuous use and replenishment, is in contact with nitrogen for a long time, and the lubricating oil will still absorb the moisture in the nitrogen, causing the oil quality to deteriorate), and the moisture in the nitrogen is not easy to enter the lubricating oil, and thus is not easy to affect the quality of the lubricating oil.

[0046] By integrating the existing oil purification tank and oil storage tank into one oil tank 2, the occupied area is reduced and the utilization rate of the oil tank 2 is improved.

[0047] Embodiment 2:

[0048] like Figure 3 As shown, the number of the oil tanks 2 can be multiple. Taking the present embodiment 2 as an example, the number of the oil tanks 2 is 2, and the two oil tanks 2 are independently arranged. When the lubricating oil in one of the oil tanks 2 is completely used up, the lubricating oil can be refilled, purified, and stored. At the same time, the lubricating oil in the other oil tank 2 is used to realize the repeated alternating use of the two oil tanks 2.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
