Description

Technical Field

[0001] The utility model relates to a transfer device for sending oil in an oil tank to the outside, in particular to a safe and reliable floating oil outlet device suitable for sending oil from various types of oil tanks. Background Art

[0002] Currently, traditional oil storage tanks use the outlet pipe at the bottom of the tank to directly transport oil to external locations. During oil distribution, impurities and moisture deposited at the bottom of the tank are easily carried out, resulting in poor oil quality and increasing the workload of downstream purification equipment such as filter separators. This presents certain drawbacks in applications requiring high oil quality, frequent transfers, and short oil settling times. The use of a floating oil tank outlet effectively avoids these drawbacks. The floating oil tank outlet rises and falls with the liquid level, consistently extracting clean oil from the surface, thus ensuring the cleanliness of the oil being distributed externally. The floating oil tank outlet is a core component of an oil depot's external oil distribution operations, and its safety and reliability are paramount.

[0003] The floating oil discharge device is a purification device that extracts surface oil from tanks and improves the quality of oil delivered from them. It is suitable for all types of vertical or horizontal oil storage tanks. The floating oil discharge device utilizes an intelligent design that rises and falls with the tank liquid level, requiring no manual intervention. This design simplifies the operation process and improves efficiency. Compared to traditional bottom-of-tank oil discharge, it offers advantages such as higher oil delivery quality, shorter oil settling time, and faster tank equipment turnover. It is a key method for ensuring oil delivery quality in airports, refineries, seaports, docks, military oil depots, and other locations.

[0004] While existing designs for floating oil outlets exist, there's a risk of collision between the rotating joint and the welded bracket during the unit's floating motion, potentially damaging the equipment. Furthermore, the support beneath the rotating joint is a gate-shaped bracket welded to the bottom of the tank, which can't be adjusted in height, making installation difficult. The top elbow support also can't be adjusted in height, making installation difficult. Utility Model Content

[0005] In order to solve the problems existing in the above technologies, the technical problem to be solved by the present invention is to provide an oil tank floating oil discharge device to improve the safety and reliability of the oil body sending operation of the oil storage tank, reduce the operating risk, and extend the maintenance and inspection cycle and service life of the floating oil discharge device equipment.

[0006] Specifically, the utility model proposes a floating oil outlet device, which includes: a floating oil pipe in an oil tank and a connecting frame located in the oil tank and connected to an inner floating plate;

[0007] One end of the floating oil pipe is connected to the oil outlet pipe at the bottom of the oil tank, and the other end of the floating oil pipe is a top elbow for oil outlet. There is a floating pipe between the oil outlet pipe and the top elbow. The oil outlet pipe is connected to the floating pipe through a first rotary joint, and the top elbow is connected to the floating pipe through a flange.

[0008] A floating barrel is provided on the outer wall of the floating pipe, and the floating barrel is fixedly connected to the outer wall of the floating pipe.

[0009] In the described floating oil outlet device, the floating barrel is fixedly connected to the floating pipe through a steel belt, and a limit bolt is installed on the outer side of the steel belt to further tighten the connection between the floating barrel and the floating pipe.

[0010] In the described floating oil outlet device, a support structure for supporting the first rotary joint is provided on the outer wall of the first rotary joint. The support structure includes a plurality of support rods, and an oil-resistant nylon pad for contacting the bottom of the oil tank is installed at the bottom of each support rod.

[0011] In the described floating oil outlet device, an intermediate support for support is provided on the floating pipe. The support is fixedly connected to the floating pipe through a stainless steel belt, and an oil-resistant nylon pad is installed at the bottom of the support.

[0012] In the described floating oil outlet device, an anti-vortex plate is further provided at one end of the top elbow for oil outlet. The diameter of the anti-vortex plate is larger than the pipe diameter of the top elbow; and a support foot extending outward along the oil outlet direction is provided at one end of the anti-vortex plate for oil outlet, and an oil-resistant nylon pad is provided at the bottom of the support foot. The oil outlet direction is as Figure 6 shown by the arrow.

[0013] In the described floating oil outlet device, the connection frame is welded with aluminum profiles, and the structural shape is a square frame in the shape of a Chinese character 'Mu'.

[0014] In the described floating oil outlet device, an oil leakage and exhaust hole is designed at the lifting lug at the upper part of the top elbow, and oil leakage and exhaust holes for discharging the air inside the floating oil outlet device after oil inlet are provided at both the bottom swing elbow and the middle swing elbow.

[0015] In the described floating oil outlet device, the floating oil outlet device is a folding arm type floating oil outlet device. The floating pipe includes an upper floating pipe and a lower floating pipe. One end of the upper floating pipe is connected to the flange of the top elbow, the other end of the upper floating pipe is connected to the lower floating pipe through a second rotary joint, and the lower floating pipe is connected to the oil outlet pipe through the first rotary joint.

[0016] In the described floating oil outlet device, the second rotary joint has a hoop support for buffering and support. The hoop support is fixedly connected to the second rotary joint through a stainless steel belt at the top, and an oil-resistant nylon pad is installed at the bottom of the hoop support.

[0017] From the above scheme, it can be seen that the advantages of the present invention are:

[0018] The utility model changes the support below the rotary joint at the bottom of the floating oil outlet device of the oil tank into a four-legged support with an adjustable height structure, which is easy to install and has a more stable support; the rotary joint between the floating pipes in the floating oil outlet device with a folding arm structure rises and falls with the rise and fall of the liquid level, and is independent of the door-type bracket welded on the bottom of the tank. After the floating oil outlet device descends to a certain position, the rotary joint between the floating pipes falls on the support, and a certain collision occurs between the two. After technical optimization of the present invention, the support under the rotary joint between the floating pipes is improved to a support of a clamp-type structure, and the support and the rotary joint are integrated, and the two rise and fall together; the connection frame between the floating oil outlet device of the folding arm structure and the inner floating plate is unified into an I-shaped structure. Now the technology is optimized, and the structure of the inner floating plate can be flexibly adjusted according to the size of the diameter of the floating oil outlet device. The connection frame between the large-diameter floating oil outlet device and the inner floating plate is changed to a mesh shape, which has a more balanced force and a more stable structure; the buoy and the floating pipe are fastened by a connecting steel belt. After technical optimization, a limit bolt is installed on the outside of the steel belt for double insurance, thereby ensuring that the connection between the steel belt and the buoy is tighter and more reliable, and ensuring that the buoy will not be displaced.

[0049] It should be noted that, in this application, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0050] Without further constraints, an element defined by the phrase "comprises a..." does not preclude the existence of additional identical elements in the process, method, article or apparatus that includes the element.

[0051] It should also be understood that in various embodiments of the present invention, the size of the serial numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0052] In the several embodiments provided in the present invention, it should be understood that the disclosed devices, apparatuses and methods can be implemented in other ways. For example, the device embodiments described above are merely illustrative. For example, the division of the units is merely a logical function division. In actual implementation, there may be other division methods, such as multiple units or components can be combined or integrated into another device, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be through some interfaces, indirect coupling or communication connection of devices or units, which can be electrical, mechanical or other forms.

[0053] The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed across multiple network units. Some or all of these units may be selected to achieve the purpose of the solution of this embodiment according to actual needs.

[0054] In order to meet the above technical problems, the floating oil outlet device provided by the utility model includes: a connecting elbow, at least one rotary joint, a bottom swing arm elbow, a lower floating pipe, an upper floating pipe, a top elbow (including a lifting ear), a buoy, an anti-vortex plate, a four-leg support, a four-leg support adjusting screw, a buoy steel belt, a limit bolt, an intermediate support, a clamp bracket (including a steel belt), a wire rope, a connecting frame, etc.

[0055] Preferably, the oil tank floating oil outlet device is designed as a single-arm type or a folding-arm type according to the shape and structure of the oil tank. The single-arm oil tank floating oil outlet device only needs a rotary joint, which is connected to the connecting elbow at the flange of the oil tank outlet pipe. Figure 2a and Figure 2b The folding arm floating oil outlet device requires two rotary joints, the first rotary joint and the second rotary joint. The first rotary joint is installed at the bottom of the floating oil outlet device, that is, it is connected to the connecting elbow at the flange of the oil tank outlet pipe. The second rotary joint is installed at the connection between the upper floating pipe and the lower floating pipe, see Figure 1.

[0056] The float of the oil tank floating outlet device is preferably connected to the floating pipe by a stainless steel band. To ensure the reliable fixation of the float on the floating pipe, set screws are installed next to the steel band. This inherent structural design doubles the guarantee of reliable and secure installation of the float.

[0057] The first rotary joint of the floating oil discharge system for oil tanks is preferably fixed with a four-legged support structure. To accommodate the tilt angle of the tank bottom, the four support screws are designed to be adjustable. Oil-resistant nylon pads are installed at the bottom of the support screws to prevent direct contact with the iron plate at the bottom of the tank, ensuring the safety and reliability of the system during use.

[0058] Ideally, when the lower floating pipe of a folding-arm floating oil outlet system is long, an intermediate support is installed. To accommodate the tilt angle of the tank bottom, one of the support screws is designed to be adjustable, ensuring that the lower floating pipe does not deform slightly due to its large span and deadweight at low liquid levels. Furthermore, an oil-resistant nylon pad is installed at the bottom of the support screw to prevent direct contact with the iron plate at the bottom of the tank, ensuring the safety and reliability of the system during use.

[0059] The second rotary joint of the tank's folding-arm floating oil outlet device is preferably supported by a clamp bracket structure, which is connected to the second rotary joint via a stainless steel band. When discharging oil, the floating oil outlet device drives the clamp bracket to float up and down with the oil. Furthermore, an oil-resistant nylon pad is installed at the bottom of the clamp bracket, preventing direct contact with the iron plate at the bottom of the tank, ensuring the safety and reliability of the device during use.

[0060] Preferably, the support legs on the top elbow feature height adjustment. Depending on the diameter of the floating oil outlet, the support height can be adjusted by adjusting the adjustment mechanism on the corresponding top elbow. Oil-resistant nylon pads are installed on the bottom of the support legs to prevent direct contact with the metal plate at the bottom of the oil tank, ensuring the safety and reliability of the device during use.

[0061] Preferably, the top elbow is further provided with an anti-vortex plate, located below the radial oil outlet, and having a diameter greater than the diameter of the top elbow. The anti-vortex plate prevents vortices from forming when the oil flows in radially, and prevents oscillation caused by the vortex, thereby making the oil suction process more stable and reliable.

[0062] Preferably, the upper part of the top elbow is designed with a lifting lug, which is connected to the connecting frame on the floating plate in the oil storage tank through a stainless steel wire rope. The connecting frame is made of high-quality aluminum profiles to ensure that it will not corrode or generate static electricity when in contact with oil. The upper lifting lug of the top elbow is connected to the connecting frame of the floating plate through a wire rope. The small-diameter floating tube and the inner floating plate connecting frame are I-shaped, and the large-diameter floating tube and the inner floating plate connecting frame are mesh-shaped. The I-shaped and mesh-shaped connecting frames can ensure that the tension position of the entire device in the oil is always in the center of the floating plate, and the buoyancy generated by the float on the connecting frame ensures that the tension value of the wire rope on the lifting lug is within a safe range, which ensures the safety and reliability of the device during use from a design perspective.

[0063] Preferably, an oil seepage vent hole is designed at the upper lifting ear of the top elbow, and an oil seepage vent hole is also designed at the bottom swing arm elbow and the middle swing arm elbow to ensure that the air inside the floating oil outlet device can be quickly discharged after the oil is filled, to ensure that the buoyancy configuration of the entire device in the oil is always in the correctly designed state, and to ensure the safety and reliability of the device during use.

[0064] To make the above-mentioned features and effects of the present invention more clearly and understandably illustrated, the following examples are specifically described below in detail with reference to the accompanying drawings.

Figure 2a and Figure 2b The straight-arm floating oil outlet device rotary joint (first rotary joint) 2 is connected to the connecting elbow 3 .

[0068] Preferably, Figure 3 After the buoy 4 is connected to the floating tube via the buoy steel band 11, it is secured securely to the tube via the stop bolts 10, which are fastened to the threaded holes in the tube. The buoy's function is to offset the weight of the tube through its own buoyancy, reducing the tension in the wire rope and ensuring stable ascent and descent of the device.

[0069] Preferably, Figure 4 The fixed support for the first rotary joint 2 of the oil tank floating oil discharge device utilizes a four-legged support structure 9. To accommodate the tilt angle of the tank bottom, the four support screws 7 of the four-legged support structure 9 are designed to be adjustable. Oil-resistant nylon pads 8 are installed at the bottom of the support screws 7 to prevent direct contact with the iron plate at the tank bottom, ensuring the safety and reliability of the device during use.

[0070] Example 2

When discharging oil, the floating oil outlet and the clamp bracket float up and down together. An oil-resistant nylon pad 14 is installed at the bottom of the clamp bracket to prevent direct contact with the iron plate at the bottom of the tank, ensuring the safety and reliability of the device during use.

[0072] Preferably, Figure 5 The lower floating pipe of the oil tank floating outlet device is supported by an intermediate support 12. To accommodate the tilt angle of the tank bottom, the support screw of the intermediate support 12 is designed to be adjustable. An oil-resistant nylon pad is installed at the bottom of the support screw to prevent direct contact with the iron plate at the tank bottom, ensuring the safety and reliability of the device during use.

[0073] Preferably, Figure 6 The support legs 16 on the vortex prevention plate 17 are adjustable in length (height). The support height is adjusted to suit the different calibers of floating oil outlets by adjusting the adjustment mechanism on the support legs 16 on the corresponding vortex prevention plate 17. Oil-resistant nylon pads are installed on the bottom of the support legs to prevent direct contact with the iron plate at the bottom of the oil tank, ensuring the safety and reliability of the device during use.

[0074] Preferably, Figure 6The top elbow 18 is provided with a lifting lug 19, which is connected to a connecting frame 21 on a floating plate in the oil tank via a stainless steel wire rope 20. The connecting frame 21 is made of high-quality aluminum profiles to ensure that it will not corrode or generate static electricity when in contact with the oil.

[0075] Preferably, if Figure 6 As shown, in this embodiment, the oil outlet provided on the top elbow 18 is a radial oil outlet. Furthermore, in this embodiment, an anti-vortex plate 17 is provided on the top elbow 18. Anti-vortex plate 17 is located below the radial oil outlet and has a diameter greater than the diameter of the top elbow 18. Anti-vortex plate 17 prevents vortices from forming when the oil flows in.

[0076] Preferably, Figure 7 The upper lug 19 of the top elbow 18 is connected to the connecting frame 21 of the inner float via a wire rope 20. The connecting frame structure of the large-diameter floating oil outlet device is a square frame, which is more stable than the previous I-shaped structure. The square connecting frame ensures that the tension position of the entire device in the oil is always centered on the float. The buoyancy generated by the float on the connecting frame ensures that the wire rope tension value on the lug remains within a safe range. This design ensures the safety and reliability of the device during use and protects the inner float.

[0077] Preferably, Figure 1a and Figure 1b An oil seepage vent hole is designed at the upper lifting ear of the top elbow 18, and an oil seepage vent hole is also designed at the bottom swing arm elbow 3 and the middle swing arm elbow to ensure that the air inside the floating oil outlet device can be quickly discharged after the oil is filled, ensuring that the buoyancy configuration of the entire device in the oil is always in the correctly designed state, ensuring the safety and reliability of the device during use.
