Description

Technical Field

[0001] The invention relates to the field of oil and gas storage, and in particular to a micro-positive pressure loss-free oil storage tank. Background Art

[0002] Oil storage tank is a container for storing oil. According to the material, it can be divided into two categories: non-metallic oil tank and metal oil tank. Metal oil tank is widely used because of its low cost, no leakage, convenient construction and easy maintenance. Metal oil tank can be divided into three types according to shape: vertical cylindrical, horizontal cylindrical and spherical.

[0003] At present, horizontal cylindrical oil tanks are widely used. This is mainly because they have the ability to withstand higher positive and negative pressures, and are conducive to reducing the evaporation loss of oil products. However, their shortcomings are also obvious. Due to their overall horizontal design, they occupy a large area and are extremely inconvenient to transport and hoist. The main problem with vertical cylindrical oil tanks is that most oil products are volatile, so the tank will swell. In particular, the bottom of the vertical cylindrical oil tank will bear greater pressure, which will cause the bottom of the tank to deform over time, resulting in the unstable placement of the tank and the phenomenon of the tank falling over, which poses a great safety hazard. In addition, in the process of mutual transportation between the oil tank and the tank truck, since most of them use oil pumps for transportation, volatile losses are inevitable.

[0004] Therefore, in summary, it is necessary to propose a micro-positive pressure loss-free oil storage tank, which combines the advantages of vertical cylindrical oil tanks and horizontal cylindrical oil tanks, while greatly reducing the loss of oil during transportation. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems existing in the prior art and to provide a micro-positive pressure loss-free oil storage tank, which is characterized in that the tank body itself will not be deformed while being in a micro-positive pressure state and the oil is not easy to evaporate and lose, it is convenient to lift and transport and occupies a small area, and at the same time, there is almost no oil loss during the oil transportation process.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a micro-positive pressure loss-free oil storage tank, including a tank body, the tank body is a cylindrical hollow cylinder structure, the upper end of which is provided with a tank top, and the lower end is provided with a tank bottom; the load-bearing rod runs through the interior of the tank body, one end is connected to the tank top, and the other end is connected to the tank bottom; the gas phase port is arranged at the tank top; the liquid phase port is arranged at the bottom of the tank body.

[0007] As an optimization, the upper end of the load-bearing rod is an inner hollow structure, and the outer surface thereof is surrounded by equidistant opening grooves; the gas phase port is located at the center of the tank top, so that the gas can be discharged from the gas port.

[0008] As an optimization, the tank top and tank bottom are both arc-shaped structures, the tank top is convex outward relative to the tank body, and the tank bottom is concave inward relative to the tank body. The tank top is convex outward and the tank bottom is concave inward, which enhances the stability of the overall structure and ensures that the tank bottom will not deform.

[0009] As an optimization, a load-bearing ear plate is provided at the lower end of the load-bearing rod; a plurality of the load-bearing ear plates are provided around the center of the load-bearing rod at equal intervals; an inner wall ear plate is provided on the inner wall of the tank body; the water level position of the inner wall ear plate is higher than the horizontal position of the load-bearing ear plate, and the number and position of the two are matched with each other, and are connected by a drawstring. The drawstring transfers part of the force to the tank body, reducing the pressure on the tank bottom.

[0010] As an optimization, reinforcing ribs are provided between the upper end of the load-bearing rod and the tank top and between the lower end of the load-bearing rod and the tank bottom to further strengthen the structure of the tank top and tank bottom.

[0011] As an optimization, a support seat flush with the bottom surface of the tank bottom is provided at the lower end of the bottom groove surface of the tank bottom; the support seat is in a "cross" structure, and a pressure sensor is provided at the middle intersection; a compression spring is provided between the upper end of the pressure sensor and the tank bottom. In order to prevent the tank bottom from deforming and causing the tank to swell, the pressure of the tank bottom is monitored in real time through the compression spring and the pressure sensor.

[0012] As an optimization, a gas flow meter is provided on the gas phase port; and a liquid flow meter is provided on the liquid phase port.

[0013] As an optimization, a lifting lug is provided on the outer periphery of the tank body; the lifting lug is provided in plurality and is equidistantly arranged at the upper end of the outer wall of the tank body around the center of the tank body, so as to facilitate handling and transportation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: first, the traditional oil tank storage method is changed, and the commonly used horizontal cylindrical oil tank is replaced by a vertical cylindrical oil tank, which greatly saves the floor space and improves the convenience of transportation; secondly, since the stored oil products are mostly volatile, the tank body will expand and deform. By improving the design of the tank top and tank bottom and adding load-bearing rods and related structures, the pressure on the tank bottom is greatly shared to ensure that the tank bottom will not undergo a large deformation; thirdly, a pressure sensor and corresponding devices are added to the bottom of the tank to monitor the pressure so as to make timely adjustments to prevent problems from occurring; finally, the oil in the tank body is transported through the gas phase port and the liquid phase port, so that the oil is always in a sealed state and is transported by pressure to reduce the loss of oil during the oil transportation process.

The drawstring transfers part of the force to the tank body, thereby reducing the pressure on the tank bottom.

[0025] Reinforcement ribs 14 are provided between the upper end of the load-bearing rod 4 and the tank top 2 and between the lower end of the load-bearing rod 4 and the tank bottom 3 to further strengthen the structure of the tank top and tank bottom.

[0027] The gas phase port 5 is provided with a gas flow meter 7 ; the liquid phase port is provided with a liquid flow meter 8 .

[0028] The outer periphery of the tank body 1 is provided with a lifting lug plate 11; the lifting lug plates 11 are provided in plurality and are equidistantly arranged around the center of the tank body 1 at the upper end of the outer wall of the tank body 1, so as to facilitate handling and transportation.

[0029] Working principle:

[0030] When the oil in the tank body 1 needs to be transported and transferred, the gas phase port 5 and the liquid phase port 6 are connected to the outlet and inlet of the tank truck respectively. When the oil needs to be transferred from the tank body 1 to the tank truck, the gas in the tank truck is pumped from the outlet to the gas phase port 5 of the tank body 1 by the transfer pump, and the oil in the tank body 1 is transported from the liquid phase port 6 to the inlet of the tank truck through the pressure.

[0031] When the oil in the tank truck needs to be transported to the tank body 1, the gas in the tank body 1 is pumped from the gas phase port 5 to the outlet of the tank truck through the transfer pump, and the oil in the tank truck is transported from the inlet of the tank truck to the liquid phase port of the tank body 1 through the pressure.

[0032] The physical quantity of the transported material is measured by the gas flow meter 7 and the liquid flow meter 8 for monitoring. Specific embodiment 1:

[0034] Combination Figure 1 In Example 1, the top of the load-bearing rod 4 is connected to the tank top 2, and the gas phase port 5 is provided at the tank top 2, but is not located at the center of the tank top 2, so there will be a certain amount of oil loss during the transmission process. Specific embodiment 2:

[0036] Combination Figure 2 In Example 2, the top of the load-bearing rod 4 is not connected to the tank top 2, but is connected to the tank top 2 through the reinforcing rib 14. Therefore, when the tank body 1 expands due to the volatilization of the oil, an upward pulling force is also provided to the tank bottom 3 through the load-bearing rod 4 to reduce the pressure on the tank bottom 3. Here, the gas phase port 5 is set at the center of the tank top 2, so that the oil will not be lost during the transmission process. Specific embodiment 3:

[0038] Combination Figure 3 and Figure 5 In Example 3, the top of the load-bearing rod 4 is connected to the tank top 2, but the top of the load-bearing rod 4 is an inner hollow structure, and the outer surface thereof is surrounded by equidistant opening grooves. The gas phase port 5 is located at the center of the tank top 2. Through this design, the top of the load-bearing rod 4 is connected to the tank top 2, and is reinforced by the reinforcing ribs 14, which distributes the force and increases the pressure on the tank bottom 3. At the same time, it also satisfies the function of preventing oil loss during the transmission process.

The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific implementation.
