For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Refer to the following Figure 1 to Figure 2 The utility model introduces an oil storage system.
[0033] like Figure 1 As shown, in this embodiment, the oil storage system mainly includes an oil tank 1, a bubbling device, an air supply device and a circulation device. Among them, the oil tank 1 is used to store oil products, and a heating pipe for heating the oil products is provided at the bottom thereof to ensure that the oil products are at a suitable storage temperature. The bubbling device is arranged in the oil tank 1 and is located at the bottom of the oil tank 1. The air supply device is connected to the bubbling device and can input gas to the bubbling device to generate bubbles in the oil tank 1 comprehensively and evenly through the bubbling device, thereby achieving the effect of stirring the oil products. The circulation device is connected to the oil tank 1 and can extract the oil products in the oil tank 1 from the bottom of the oil tank 1 and input it again into the middle or top of the oil tank 1, so that the oil products in the oil tank 1 are in a flowing state.
[0034] Specifically, during use, the air supply device and the bubbling device can be used alone to stir the oil in the oil tank 1 evenly, thereby reducing the generation of oil residue and avoiding stratification. The circulation device can also be used alone to keep the oil in the oil tank 1 in a flowing state, which can also reduce the generation of oil residue and avoid stratification. Compared with the flowing state, the bubbling device can generate bubbles in the oil tank 1 comprehensively and evenly, so as to stir the oil in a larger range, thereby avoiding the risk of slow flow rate in some parts (such as locations far away from the oil outlet and the oil inlet) that are prone to the generation of oil residue and other sediments. Compared with bubble stirring, the circulation device can redistribute the heavier components in the oil that are easily deposited at the bottom to the middle or top, thereby more effectively avoiding the generation of stratification.
[0035] Of course, in some embodiments, the air supply device, the bubbling device and the circulation device can also be used simultaneously, so that the oil is in a state of stirring and flowing at the same time, thereby achieving a better effect of reducing the generation of sediments such as oil residues and avoiding stratification, which is also within the scope of protection of the present utility model.
[0036] The oil storage system can stir the oil in the oil tank 1 comprehensively and evenly through the bubbling device and the air supply device, so as to avoid the local generation of oil residues inside the oil tank 1, and can make the oil in the oil tank 1 flow through the circulation device, so as to slow down the occurrence of stratification, so that the oil storage system can ensure the quality of the oil and the reliability of its use during the long-term storage of the oil, thereby reducing the production cost of the glass, and ensuring that the heating pipe in the oil tank 1 and the oil gun and pipeline connected to the oil tank 1 are in normal working condition, thereby reducing the failure rate and maintenance frequency of the entire oil storage system, thereby reducing the maintenance cost of the oil storage system.
[0037] Specifically, refer to Figure 1 , Figure 2 As shown, in this embodiment, the bubbling device includes a plurality of bubbling tubes 22 and a connecting body 21, the connecting body 21 is connected to the gas supply device, and the plurality of bubbling tubes 22 are connected to the connecting body 21 and are evenly arranged in the oil tank 1 along the horizontal plane. The bubbling tubes 22 are all straight tubes with low manufacturing costs, and along the axial direction of the bubbling tubes 22, a plurality of bubbling holes 221 are installed on the bubbling tubes 22 at a preset spacing. When the gas supply device inputs gas to the bubbling device, the gas will flow evenly into each bubbling tube 22 through the connecting body 21, and evenly form bubbles in the oil tank 1 through the plurality of bubbling holes 221, thereby comprehensively and evenly stirring the oil product.
[0038] More specifically, if Figure 2 As shown, the connecting body 21 is an annular pipe, and a plurality of bubbling tubes 22 are arranged to rotate circumferentially with the connecting body 21 as the center, so as to evenly arrange the bubbling holes 221 in the oil tank 1 along the horizontal plane. The aperture of the bubbling hole 221 is preferably 6 mm, so that the size of the bubble generated has a better stirring effect. Preferably, the bubbling tube 22 is set at a preset distance from the bottom of the oil tank 1 to prevent the oil residue deposited at the bottom of the oil tank 1 from clogging the bubbling hole 221. At the same time, since the fluidity of the oil product will increase with the increase of height, the preset distance can also reduce the pressure requirement of the air supply device. Exemplarily, the preset distance is 0.5m.
[0039] Further preferably, Figure 2 As shown, the bubbling holes 221 of two adjacent bubbling tubes 22 are staggered, so that bubbles are generated more comprehensively and evenly in the oil tank 1, the oil product is stirred, and the phenomenon of oil residue being easily generated locally is avoided. For example, in this embodiment, the bubbling holes 221 on one bubbling tube 22 are arranged at a spacing of 3 cm, and the bubbling holes 221 at the air inlet end of the bubbling tube 22 are arranged at a distance of 1.5 cm from the connecting body 21. The bubbling holes 221 on another adjacent bubbling tube 22 are also arranged at a spacing of 3 cm, and the bubbling holes 221 at the air inlet end of the bubbling tube 22 are arranged at a distance of 3 cm from the connecting body 21, so that the bubbling holes 221 of the two adjacent bubbling tubes 22 are staggered.
[0040] Reference Figure 1 As shown, in this embodiment, the gas supply device includes a gas supply pipeline 31 and a gas pretreatment device 32 connected to the gas supply pipeline 31. The gas pretreatment device 32 includes at least one of a supercharger, a cold dryer and a gas storage tank, and the gas supply pipeline 31 is connected to the bubbling device. The supercharger can be a screw machine, which can pressurize the air and input it into the bubbling device. The cold dryer can remove moisture and some impurities in the air to avoid affecting the water content of the oil. The gas storage tank can play a buffering role to ensure the consistency and continuity of bubble generation.
[0041] Continue to refer to Figure 1 As shown, the circulation device includes an oil extraction pipeline 41, a circulating oil pump 42 and an oil inlet pipeline 43. The bottom of the oil tank 1 is provided with a first oil extraction port 11 and a second oil extraction port 12 located at different heights, and the first oil extraction port 11 and the second oil extraction port 12 are both connected to the oil extraction pipeline 41. The top of the oil tank 1 is also provided with an oil discharge port 13, which is connected to the oil inlet pipeline 43. The oil can flow out of the oil tank 1 from the first oil extraction port 11 and / or the second oil extraction port 12 under the drive of the circulating oil pump 42, and flow into the oil tank 1 through the oil extraction pipeline 41, the oil inlet pipeline 43 and the oil discharge port 13.
[0042] For example, in this embodiment, the first oil extraction port 11 is located at a height of 0.8 m, and the second oil extraction port 12 is located at a height of 2 m. When there is a lot of sediment at the bottom of the oil tank 1, oil can be extracted through the second oil extraction port 12 to avoid extracting a lot of oil residue. When there is less sediment at the bottom of the oil tank 1, oil can be extracted through the first oil extraction port 11 or the first oil extraction port 11 and the second oil extraction port 12.
[0043] Preferably, the circulation device further comprises a filter 44, and the filter 44 is used to filter the oil residue in the oil product. Figure 1 As shown, the filter 44 is connected to the oil inlet of the circulating oil pump 42 and can filter the oil residue before it enters the circulating oil pump 42 to ensure the normal operation and service life of the circulating oil pump 42.
[0044] Continue to refer to Figure 1 As shown, the oil storage system also includes an oil unloading pool 51 and an oil unloading pipe 52. When the newly purchased oil is transported to the outside of the oil tank 1 area by a transport device such as an oil tanker, it is first transferred from the oil tank to the oil unloading pool 51, so that the oil tank is in an empty state, and then driven by the oil unloading pump 53, the oil is input from the oil unloading pool 51 to the oil tank 1 through the oil unloading pipe 52 (this process is the oil unloading process).
[0045] Preferably, in this embodiment, the oil tank 1 is also provided with a circulating oil inlet 14, which is connected to the oil inlet pipeline 43, and a switch valve 72 is provided between the circulating oil inlet 14 and the oil unloading port 13, so that the oil storage system can simultaneously realize circulation and oil unloading through the circulating oil inlet 14 and the oil unloading port 13 to meet the needs of different scenarios. Optionally, the circulating oil inlet 14 is extended in the oil tank 1 to form an extension pipe 15, and the end of the extension pipe 15 is extended in the oil tank 1 toward the axial direction of the oil tank 1 to enhance the fluidity of the oil in the oil tank 1 during circulation.
[0046] Alternatively, if Figure 1 As shown, the gas supply device is connected to the bubbling device through a portion of the oil inlet pipeline 43, and a first non-return valve 33 is connected between the gas supply device and the oil inlet pipeline 43. That is to say, a portion of the oil inlet pipeline 43 can be used for both oil product input during circulation and gas input during bubbling, thereby placing the relevant equipment outside the oil tank 1 area away from the oil tank 1, thereby enhancing the safety factor, and avoiding the use of too many and too long connecting pipes 71, thereby saving the pipeline cost of the oil storage system.
[0047] Preferably, the oil inlet pipeline 43 is provided with an oil discharge interface valve 431, which can be connected to the oil unloading pool 51 through the connecting pipe 71, so as to further facilitate the oil discharge, that is, to improve the efficiency of inputting the oil product from the oil tank 1 to the oil unloading pool 51. Optionally, the oil inlet pipeline 43 is also provided with a second one-way valve 432 and a switch valve 72, the second one-way valve 432 is used to prevent the oil product from flowing back, and the switch valve 72 can cut off the oil inlet pipeline 43 when the oil product needs to be input from the oil tank 1 to the oil unloading pool 51, so as to control the flow direction of the oil product.
[0048] The oil storage system also includes a dirty oil pool 61, and a dirty oil pipe 62 is provided between the dirty oil pool 61 and the oil tank 1, so that the dirty oil containing more oil residue can be directly extracted from the oil tank 1 and stored in the dirty oil pool 61. Optionally, a connecting pipe 71 is also provided between the oil unloading pool 51 and the dirty oil pool 61 to facilitate the cleaning of the oil residue and impurities in the oil unloading pool 51.
[0049] It should be noted that there are multiple locations in the oil storage system where switch valves 72 are provided that are not mentioned above. Those skilled in the art can set the switch valves 72 according to the flow requirements of the oil products, and this is not specifically limited in the present invention.
