Description

Technical Field

[0001] The invention relates to the technical field of skid-mounted refueling equipment, and in particular to an explosion-proof skid-mounted refueling device. Background Art

[0002] During transportation, storage and use, flammable and explosive hazardous chemicals such as fuel are extremely susceptible to external energy such as static electricity, gunfire, collision, etc., which can cause combustion and explosion, which often results in significant property losses and casualties.

[0003] The biggest drawback of existing skid-mounted refueling devices for storing diesel fuel is that wax precipitation will occur when the temperature is below the cold filter point (4°C) in winter, leading to blockage of oil pipelines and refueling machine filters. Once oil leakage or seepage occurs, it is easy to cause the oil and gas concentration to exceed the standard, becoming a source of explosion hazard.

[0004] There are currently two commonly used measures to prevent wax precipitation. One is to add a certain amount of pour point depressant to diesel. Not only is the process complicated and increases costs, but excessive pour point depressant will directly affect the quality of diesel. The other is to add a heating device to the insulation layer of the fuel dispenser cabinet, that is, to put the fuel dispenser's flexible pipe, oil filter, oil pump, oil-gas separator, solenoid valve, meter, oil gun hose, etc. under an insulating state to work. However, it is impossible to avoid the occurrence of low-temperature wax precipitation in the storage tank and the passage. Once the pipeline is blocked, oil leakage and oil seepage are likely to occur, which can easily cause the oil and gas concentration to exceed the standard and become an explosion hazard. Summary of the invention

[0005] In view of the above problems, the present invention provides an explosion-proof skid-mounted refueling device, which aims to solve the technical problem mentioned in the above background technology that low-temperature wax precipitation of diesel fuel leads to blockage of the passage, and once oil leakage or oil seepage occurs, it is easy to cause the oil and gas concentration to exceed the standard, leading to explosion accidents.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an explosion-proof skid-mounted refueling device, comprising an anti-collision base, an oil storage tank is provided in the middle of the anti-collision base, a plurality of tank heating mechanisms are provided in the middle of the oil storage tank, an oil pipeline is provided at one end of the oil storage tank, a pipeline heating mechanism is provided on the outside of the oil pipeline, one end of the oil pipeline is provided at the input end of the refueling machine, the refueling machine is provided at one end of the anti-collision base, an oil and gas recovery pump is provided on one side of the refueling machine, the oil and gas recovery pump is connected to the top surface of the pipeline heating mechanism through a hose, an electric boiler is provided on one side of the oil and gas recovery pump, a plurality of the tank heating mechanisms and the pipeline heating mechanism are connected to the electric boiler through a hose, and a protective frame is provided on the outside of the oil storage tank and the top surface of the anti-collision base.

Both ends of the heating driving shaft are respectively rotatably connected to the lower part of the oil storage tank. One end of the heating driving shaft is coaxially connected to the output end of a heating driving motor, and the heating driving motor is arranged at the lower part of the oil storage tank.

[0011] Furthermore, the heating blanket includes a first water heating pipe. The first water heating pipe is connected to the electric boiler through a hose.

On the other hand, combined with the heat preservation blanket, it is convenient to unfold and wrap and fold for storage. The overall structure is further protected by the anti-collision base to prevent the vehicle from directly colliding with the tank body and causing an explosion. BRIEF DESCRIPTION OF THE DRAWINGS

A protective frame 9 is provided on the outer side of the storage oil tank 2 and the top surface of the anti-collision base 1. A solar panel is provided on the top of the protective frame. The solar panel is electrically connected to the electric boiler 8, stores solar energy as electric energy when the sun is sufficient, and supplies it to the electric boiler 8 for use when needed, greatly reducing the energy consumption of the equipment.

[0034] For the embodiment, please refer to Figure 3-4 , The anti-collision base 1 includes a base body 11. A plurality of anti-collision column units 12 are provided around the base body 11. The anti-collision column unit 12 includes an anti-collision column body 121. A buffer rubber sleeve 122 is sleeved on the outer side of the middle of the anti-collision column body 121. The outer side of the buffer rubber sleeve 122 is arranged in a honeycomb shape. This design avoids the vehicle directly colliding with the storage tank through a plurality of anti-collision column units 12, resulting in a more serious explosion accident, and further absorbs the energy during collision through the buffer rubber sleeve 122 with a honeycomb-shaped outer side.

[0035] For the embodiment, please refer to Figure 5-9, the storage tank heating mechanism 3 includes a heating blanket 31. The upper end of the heating blanket 31 is arranged on one side of the heating blanket fixing rod 32. At both ends of the heating blanket fixing rod 32, limiting gears 33 are symmetrically arranged. A plurality of the limiting gears 33 are respectively rotatably connected to the outside of the heating fixing ring 34. The lower end of the heating blanket 31 is arranged at the bottom of the oil storage tank 2. On one side of each of the plurality of limiting gears 33, a heating driving gear 35 is respectively engaged. A plurality of the heating driving gears 35 are all coaxially connected to the middle of the heating driving shaft 36. Both ends of the heating driving shaft 36 are respectively rotatably connected to the lower part of the oil storage tank 2. One end of the heating driving shaft 36 is coaxially connected to the output end of the heating driving motor 37. The heating driving motor 37 is arranged at the lower part of the oil storage tank 2. The heating blanket 31 includes a first water heating pipe 311. The first water heating pipe 311 is connected to the electric boiler 8 through a hose. On one side of the first water heating pipe 311, there is a heat conduction layer 312. The lower end of the heat conduction layer 312 is arranged at the bottom of the oil storage tank 2. On the other side of the first water heating pipe 311, there is a heat preservation layer 313. The upper end of the heat preservation layer 313 is arranged on one side of the heating blanket fixing rod 32. The material of the heat conduction layer 312 is set as heat-conducting silica gel. The material of the heat preservation layer 313 is set as inner space cotton and outer tinfoil. The limiting gear 33 includes an incomplete gear 331. On one side of the incomplete gear 331, there is a fixing rod connecting block 332. The fixing rod connecting block 332 is arranged in a shape similar to "L". When heating is required, start the heating driving motor 37 to drive the heating driving shaft 36 to rotate, and then drive a plurality of heating driving gears 35 to rotate. Subsequently, the plurality of limiting gears 33 rotate. The heating blanket 31 is pulled by the heating blanket fixing rod 32 to wrap the tank body. At the same time, start the electric boiler 8 to circulate and pump hot water into the first water heating pipe 311. The heat of the hot water in the first water heating pipe 311 is transferred to the oil storage tank 2 through the heat conduction layer 312, so as to realize the heating of the oil storage tank 2. And the oil storage tank 2 is heat-preserved through the heat preservation layer 313 to reduce the loss of heat and further improve the heating effect.

[0036] For the embodiment, please refer to Figure 10-11 , the pipeline heating mechanism 5 includes a second water heating pipe 51. The second water heating pipe 51 is connected to the electric boiler 8 through a hose. The second water heating pipe 51 is wound around the outside of the oil pipeline 4. An oil and gas closed outer shell 52 is arranged outside the second water heating pipe 51. An oil and gas recovery port 53 is opened on the top surface of the oil and gas closed outer shell 52. The oil and gas recovery port 53 is connected to the oil and gas recovery pump 7 through a hose. This design circulates and pumps hot water into the second water heating pipe 51 through the electric boiler 8, so as to heat the oil pipeline 4 and avoid the phenomenon of paraffin precipitation at low temperature. Since there are many interfaces in the middle of the pipeline, it is very difficult to avoid oil and gas leakage. In order to reduce the oil and gas concentration, the leaked oil and gas are recovered through the cooperation of the oil and gas closed outer shell 52 and the oil and gas recovery pump 7, greatly reducing the probability of explosion accidents.

[0037] Operating principle: First, multiple anti-collision column units 12 are used to prevent the vehicle from directly colliding with the storage tank, which may cause a relatively serious explosion accident. The buffer rubber sleeve 122 arranged in a honeycomb shape on the outside further absorbs the energy during collision, reducing the accident losses. When heating is required, start the heating drive motor 37 to drive the heating drive shaft 36 to rotate, and then drive multiple heating drive gears 35 to rotate. Subsequently, the multiple limit gears 33 rotate, and the heating blanket 31 is pulled by the heating blanket fixing rod 32 to wrap the tank body. At the same time, start the electric boiler 8 to circulate and pump hot water into the first water heating pipe 311, and transfer the heat of the hot water in the first water heating pipe 311 to the oil storage tank 2 through the heat conduction layer 312, thereby realizing the heating of the oil storage tank 2, and insulating the oil storage tank 2 through the heat insulation layer 313 to reduce heat loss and further improve the heating effect. Circulate and pump hot water into the second water heating pipe 51 through the electric boiler 8 to heat the oil pipeline 4 to avoid the phenomenon of paraffin precipitation at low temperature. When the temperature of the tank body is relatively high, turn off the electric boiler 8 and reverse-start the heating drive motor 37 to fold and store the heating blanket 31 and stop heating. Since there are many interfaces in the middle of the pipeline, it is very difficult to avoid oil and gas leakage. In order to reduce the oil and gas concentration, the leaked oil and gas are recovered through the oil and gas closed housing 52 and the oil and gas recovery pump 7, greatly reducing the probability of explosion accidents. Store solar energy as electric energy when the sun is sufficient and supply it to the electric boiler 8 when needed, greatly reducing the energy consumption of the equipment.
