[0040] like Figure 1 and Figure 2 As shown, the present application provides a dual-chamber insulated oil storage tank 1, comprising:

[0041] The tank body 11 is provided with a partition plate 13 to separate the tank body 11 into a first cavity 111 and a second cavity 112.

[0042] The heating component 13 is disposed in the first cavity 111 and is used to heat the first cavity 111. The heating component 13 includes a heating element and a heat sink. The heat sink covers the heating element. The heating element transfers heat to the tank body 11 through the heat sink.

[0043] In this embodiment, at the oilfield drilling and repair operation site, the double-chamber insulated oil storage tank 1 is required to reserve diesel to provide power for generators, engines and other equipment.

[0044] like Figure 1 As shown, the present application provides a dual-chamber insulated oil storage tank 1, the oil storage tank includes a tank body 11 and a heating assembly 13, a partition plate 13 is arranged in the tank body 11, the tank body 11 is partitioned by the partition plate 13 to form a first cavity 111 and a second cavity 112, a heating assembly 13 is arranged in the first cavity 111, the heating assembly 13 is used to heat the oil in the first cavity 111, the heating assembly 13 includes a heating element and a heat sink, the heat sink is arranged outside the heating element, and is used to cover the heating element, so as to increase the temperature in the first cavity 111 and avoid the oil in the first cavity 111 from solidifying and freezing, and the heating element is not in direct contact with the oil, and the heat dissipated by the heating element is transferred to the first cavity 111 through the heat sink, thereby improving safety and reliability, so as to avoid danger while heating the oil in the first cavity 111.

[0045] During winter operations, the first cavity 111 and the second cavity 112 can be respectively filled with oils of different grades, with the first cavity 111 filled with high-grade ordinary oil and the second cavity 112 filled with low-grade winter oil. Thus, the equipment is first started and preheated with the low-grade winter oil in the second cavity 112. After the equipment is operating normally, the ordinary high-grade oil heated in the first cavity 111 is used to meet the equipment operation requirements. High-grade ordinary oil is less expensive than low-grade winter oil, thereby avoiding the problem of increased costs caused by the continuous use of low-grade winter oil in the related art.

[0046] Therefore, the double-chamber insulated oil storage tank 1 provided by the present application can accommodate different types of oil products in the first cavity 111 and the second cavity 112 by dividing the tank body 11, and a heating component 13 is arranged in the first cavity 111 for holding ordinary oil products, so that ordinary oil products can increase their temperature under the heating of the heating component 13 to avoid the occurrence of solidification and freezing, thereby meeting the startup and normal operation of the equipment, while ensuring normal operation in winter, reducing costs, and having a reasonable design, safe and reliable operation, and simple and convenient operation. When applied to drilling and well repair construction sites, it can not only realize the use of high-grade diesel in low-temperature cold environments, but also save production and operation costs for operating projects.

[0047] In this embodiment, the partition plate 13 in the middle of the tank body 11 is designed as an integral unit with the tank body 11 , so as to have higher strength.

[0048] like Figure 1 and Figure 3 As shown, in the embodiment of the present application, the heating element is a heating tube 131, the heat sink is a heat sink 132 sleeved outside the heating tube 131, and spiral heat sinks 133 are provided on the side wall of the heat sink 132 along the length direction.

[0049] In this embodiment, the heating tube 131 is used to generate heat, and the heat dissipation sleeve 132 is sleeved outside the heating tube 131, and is used to conduct the heat of the heating tube 131 to the first cavity 111, so as to heat the oil in the first cavity 111, so as to increase the temperature of the oil in the first cavity 111, and prevent the oil in the first cavity 111 from solidifying and freezing due to too low temperature. In addition, the heat dissipation sleeve 132 is also provided with spiral heat dissipation fins 133 along the length direction, and the provision of the spiral heat dissipation fins 133 can improve the heat dissipation effect, thereby reducing the temperature rise time of the oil in the first cavity 111 and improving the temperature rise efficiency.

[0050] In this embodiment, the heating assembly 13 can be extended in a straight line in the first cavity 111, or can be bent multiple times in the first cavity 111, so as to form a larger heat dissipation area and improve the heat dissipation effect. The number of heaters can be one or more, two, three, or other numbers, as long as it is suitable for production and application.

[0051] In this embodiment, the heating assembly 13 adopts a furnace design, the heating tube 131 is arranged in the heating chamber of the heat dissipation sleeve 132, and a spiral heat sink 133 is arranged outside the furnace. The heating tube 131 does not directly contact the diesel, so the operation is safe and reliable. The heating power of the heating tube 131 is 4Kw, and it is estimated that it will take 10 minutes to heat 1.45m3 of diesel from -10 degrees to 20 degrees.

[0052] In the embodiment of the present application, the heating component 13 has a non-heating section 1312 and a heating section 1312, the non-heating end is arranged close to the outer wall of the tank body 11, and the heating component 13 extends out of the tank body 11 close to the non-heating end for connection with the wiring board.

[0053] In this embodiment, the heating tube 131 corresponding to the heating section 1312 of the heating assembly 13 can generate heat, while the heating tube 131 corresponding to the non-heating section 1312 cannot generate heat. The heating tube 131 is arranged in the first cavity 111. The first cavity 111 has a bottom wall and four side walls. Three of the four side walls are side walls of the tank body 11, and one side wall is a partition plate 13. The heating tube 131 extends into the first cavity 111 through one side wall of the three side walls of the tank body 11, and has a There is a non-heating section 1312, and the part away from the side wall has a heating section 1312, and the non-heating section 1312 close to the side wall is used to connect with the wiring board outside the tank body 11. The heating component 13 is connected to the power supply through the wiring board to receive an electrical signal so that the heating tube 131 can generate heat, while the non-heating section 1312 does not generate heat. The non-heating section 1312 can serve as an insulating section between the heating section 1312 and the wiring board, so that the wiring board is not affected by high temperature, effectively ensuring the normal operation of the system.

[0054] like Figure 4 and Figure 5 As shown, in the embodiment of the present application, the first cavity 111 is connected to the second cavity 112 via a first pipeline 14, and a first valve 15 is provided on the first pipeline 14;

[0055] When the first valve 15 is opened, the first pipeline 14 between the first cavity 111 and the second cavity 112 is in communication;

[0056] When the first valve 15 is closed, the first pipeline 14 between the first cavity 111 and the second cavity 112 is disconnected.

[0057] In this embodiment, the first cavity 111 is connected to the second cavity 112 through the first pipeline 14, and the first pipeline 14 is provided with a first valve 15. When the first valve 15 is opened, the first pipeline 14 connecting the first cavity 111 and the second cavity 112 is in a conducting state, so that the oil products can be transferred between the first cavity 111 and the second cavity 112, that is, the first cavity 111 and the second cavity 112 are equivalent to one cavity. When the first valve 15 is closed, the first pipeline 14 between the first cavity 111 and the second cavity 112 is in a disconnected state, so that the oil products cannot be transferred between the first cavity 111 and the first cavity 112, and the first cavity 111 and the second cavity 112 are two separate cavities. Therefore, in summer, when the working temperature is high, the first valve 15 is opened, and the first cavity 111 and the second cavity 112 are used as a whole cavity to store oil; when in winter, when the working temperature is low, the first valve 15 is closed, so that the first cavity 111 and the second cavity 112 cannot transfer oil to each other. The first cavity 111 contains high-grade ordinary oil (0# diesel), and the second cavity 112 contains low-grade winter oil (-35# diesel). Therefore, the equipment is first started and preheated with the low-grade winter oil in the second cavity 112. After the equipment is operating normally, the ordinary high-grade oil heated in the first cavity 111 is used, thereby reducing costs while meeting the equipment operation requirements.

[0058] like Figure 4 As shown, in this embodiment, the first valve 15 is a traffic valve.

[0059] In the embodiment of the present application, the volume of the first cavity 111 is greater than the volume of the second cavity 112 .

[0060] In this embodiment, the first cavity 111 is filled with high-grade common oil (0# diesel), and a heating component 13 is provided in the first cavity 111, so that the heating component 13 is used to heat the common oil. The second cavity 112 is filled with low-grade winter oil (-35# diesel), and the low-grade winter oil (-35# diesel) is relatively expensive. Therefore, when the present application is operated in winter, the low-grade winter oil in the second cavity 112 is first used to start and preheat the equipment. After the equipment is operating normally, the heated common high-grade oil in the first cavity 111 is used. The volume of the first cavity 111 is set to be larger than the volume of the second cavity 112, so that more low-grade common oil can be accommodated, so that the low-grade common oil in the first cavity 111 can be mainly used during winter sports, thereby further reducing costs.

[0061] In one embodiment of the present application, the total volume of the tank 11 can be 2m 3 The volume of the first cavity 111 can be 1.5m 3 The volume of the second cavity 112 can be 0.5m 3 .

[0062] In another embodiment of the present application, the size of the tank body 11 is 1.8×1.1×1, of which the size of the second cavity 112 is 0.5×1.1×1, and the volume is 0.55 cubic meters; the size of the first cavity 111 is 1.3×1.1×1, and the volume is 1.45 cubic meters. It is welded with 4 mm thick steel plates, and the total weight of the equipment is 0.8 tons.

[0063] like Figure 4 As shown, in the embodiment of the present application, it also includes:

[0064] Two external liquid level gauges 16 are respectively arranged corresponding to the first cavity 111 and the second cavity 112. The external liquid level gauge 16 has a first end and a second end. The first end extends into the upper part of the first cavity 111 or the second cavity 112 and is located above the liquid surface. The second end extends into the lower part of the first cavity 111 or the second cavity 112 and is located in the solution. The external liquid level gauge 16 is used to measure and display the liquid level heights in the first cavity 111 and the second cavity 112, respectively.

[0065] In this embodiment, the double-gun oil storage tank also includes two external liquid level gauges 16, which are respectively arranged outside the first cavity 111 and outside the second cavity 112. Each external liquid level gauge 16 is extended in the vertical direction. The external liquid level gauge 16 has a first end and a second end in the vertical direction. The first end extends into the upper part of the cavity and is connected to the space above the oil in the first cavity 111 or the second cavity 112, that is, the first end of the external liquid level gauge 16 is connected to the gas in the first cavity 111 or the second cavity 112, and the second end of the external liquid level gauge 16 extends into the lower part of the first cavity 111 or the second cavity 112, and extends into the first cavity 111 or the second cavity 112. The oil contained therein is connected to the oil product, so that after the liquid level height of the oil product changes, the liquid height in the external liquid level gauge 16 connected to the oil product tube will also change simultaneously, so that the liquid level height in the external liquid level gauge 16 is the liquid level height of the first cavity 111 or the second cavity 112, and the external liquid level gauge 16 also has a measuring mark along the vertical direction, so that the liquid level height can be determined according to the measuring mark corresponding to the liquid level height, and then the staff can understand and check the liquid level height in the first cavity 111 or the second cavity 112 through the position liquid level gauge, so as to add oil products to the first cavity 111 or the second cavity 112 in time when the liquid level height is insufficient.

[0066] In this embodiment, the external liquid level gauge 16 is a magnetic flap liquid level gauge.

[0067] In the embodiment of the present application, a thermal insulation layer is provided outside the tank body 11 , and the thermal insulation layer includes a rock wool layer, a polyurethane thermal insulation layer and / or a metal protective layer which are sequentially sleeved outside the tank body 11 .

[0068] In this embodiment, an insulation layer is further provided outside the tank body 11, and the insulation layer includes a rock wool layer, a polyurethane insulation layer and a metal protective layer which are sequentially sleeved on the outside of the tank body 11. A 50mm rock wool or a 30mm polyurethane insulation layer can be installed on the outside of the tank body 11, and a 2mm steel plate protective layer is welded or riveted on the outside of the insulation layer. The setting of the insulation layer can reduce the cooling rate of the oil in the tank body 11. At the same time, when the temperature of the oil in the tank body 11 rises, the temperature of the oil in the tank body 11 can also be insulated, thereby providing an insulation effect for the oil in the tank body 11 and reducing the heat generated by the heating component, thereby solving the problem of heat loss of the tank body 11 during use, thereby saving energy and reducing costs.

[0069] like Figure 4 As shown, in the embodiment of the present application, it also includes:

[0070] A refueling hole 18, the first cavity 111 and the second cavity 112 are provided on the tank body 11 corresponding to each other, and are used to refuel the first cavity 111 and the second cavity 112; a fuel supply pipeline,

The refueling hole 18 is used to introduce oil into the corresponding first cavity 111 or second cavity 112. The two refueling holes 18 are respectively connected to different oil supply pipelines, that is, the first cavity 111 and the second cavity 112 use different oil supply pipelines to supply oil to the first cavity 111 and the second cavity 112. The breathing valve 19 is used to prevent the tank body 11 from being damaged due to overpressure or vacuum, and at the same time can reduce the evaporation loss of the oil in the tank body 11. It is a valve that not only ensures that the space of the tank body 11 is isolated from the atmosphere within a certain pressure range, but also can communicate with the atmosphere (breathe) when the pressure exceeds or falls below this pressure range. The breathing valve 19 can not only reduce the gas emission in the tank, thereby reducing the pollution to the atmosphere, but also prevent the tank body 11 from being damaged by overpressure or instability due to ultra-vacuum, which plays a certain role in promoting safety and environmental protection. The refueling hole 18 and the outer cover of the breathing valve 19 corresponding to the first cavity 111 or the second cavity 112 are provided with an anti-theft cover 20, so that when the refueling hole 18 is used to refuel the tank body 11, the anti-theft cover 20 is opened, and the staff can add oil to the tank body 11 through the refueling hole 18. When the refueling hole 18 is not used to refuel the tank body 11, the anti-theft cover 20 is buckled and locked to prevent other people from stealing the oil in the tank body 11 through the refueling hole 18, thereby improving safety.
