The vent pipe connects to the top of the oil storage tank body. The preliminary sealing valve is disposed inside the vent pipe and seals it. The movable end of the preliminary sealing valve is bonded to the vent pipe with silicone sealant. The buffer component is disposed on the oil storage tank body. When the gas pressure inside the oil storage tank body reaches a first pre-set pressure value, the higher gas pressure can force open the preliminary sealing valve. Oil flowing along the vent chamber is blocked by the oil filter membrane, and the high-pressure gas is discharged from the vent pipe through the oil filter membrane or the buffer tube, thus completing the rapid discharge of high-pressure gas and reducing the amount of oil discharged from the vent pipe, thereby reducing the impact of excessive pressure on the oil storage tank body and the external environment.

Description

Technical Field

[0001] This invention relates to the field of oil storage tank technology, and more particularly to an explosion-proof storage tank. Background Technology

[0002] An oil storage tank is a container used to store liquid petroleum or petroleum products, and is usually made of steel. Oil storage tanks are commonly used in the production, storage, transportation, and distribution of petroleum.

[0003] Explosion-proof storage tanks are a type of oil storage tank. They are made by adding explosion-proof features to conventional oil storage tanks, including rupture covers, pressure relief valves, and fire extinguishers, to reduce losses caused by explosions or fires. Additionally, anti-static structures can be added to conventional oil storage tanks to prevent static electricity buildup from causing fires.

[0004] The invention disclosed in CN101932515B proposes an explosion-proof storage tank. The inner cavity of the tank is filled with an explosion-proof material, which is a multi-layer explosion-proof material unit made of high-porosity material. Each unit has a fixed support portion for fixing and supporting the unit, and multiple units are orderly filled into the inner cavity of the tank. Specifically, when an oil storage tank experiences violent shaking or is affected by high temperatures, its internal pressure can become excessively high. When the internal pressure of the oil storage tank rises, it is released through a pressure relief valve. However, the pressure relief valve has a limited pressure release rate. When the internal pressure of the oil storage tank is too high, the pressure relief valve cannot meet the pressure release requirement. The excessive pressure can impact the oil storage tank, or the stored oil can overflow from the tank, leading to damage to the oil storage tank or impact on the external environment. Therefore, this application proposes an explosion-proof storage tank to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention proposes an explosion-proof storage tank. When the gas pressure inside the oil storage tank reaches a first pre-pressure value, the higher gas pressure can break through the initial sealing valve plate. During the flow of oil along the venting chamber, it is blocked by the oil filter membrane. The high-pressure gas is discharged from the exhaust pipe through the oil filter membrane or the buffer pipe, thereby completing the rapid discharge of high-pressure gas. When the gas pressure reaches a second pre-pressure value, in order to prevent the oil filter membrane from obstructing the flow of oil too much, a buffer pipe is set. The higher gas pressure carries a small amount of oil around the oil filter membrane and flows into the side near the exhaust pipe through the buffer pipe, thereby reducing the amount of oil discharged from the exhaust pipe and reducing the impact of excessive pressure on the oil storage tank and the external environment.

[0032] Based on the above technical solutions, preferably, the bottom tank is a copper water tank.

[0033] The explosion-proof storage tank of the present invention has the following advantages over the prior art:

[0034] (1) Specifically, when the gas pressure inside the oil storage tank reaches the first pressure pre-value, the pressure release efficiency of the pressure relief valve of the explosion-proof storage tank cannot meet the release requirements of this gas pressure. At this time, the gas pressure can break through the initial sealing valve plate, and the high-pressure gas carries oil into the interior of the connecting pipe and into the interior of the venting chamber through the connecting pipe. During the flow of oil along the venting chamber, it will be blocked by the oil filter membrane. The high-pressure gas will be discharged from the exhaust pipe through the oil filter membrane or the buffer pipe, thereby completing the rapid discharge of high-pressure gas. When the gas pressure reaches the second pressure pre-value, in order to prevent the oil filter membrane from obstructing the flow of oil too much, a buffer pipe is set up. The higher gas pressure carries a small amount of oil around the oil filter membrane and flows into the side near the exhaust pipe through the buffer pipe. During the flow of oil towards the end near the exhaust pipe, the long stroke path can reduce the oil power, thereby reducing the amount of oil discharged from the exhaust pipe, and thus reducing the impact of excessive pressure on the oil storage tank and the external environment.

[0035] (2) By setting the height of the vertical vent section to be relatively high, the oil has a longer flow path after passing around the filter oil film. The longer flow path can reduce the power of the oil flowing to the exhaust pipe. By setting the width of the vent chamber in the vertical vent section to be the maximum, the volume of the vent chamber in the vertical vent section is maximized. The larger volume space can further reduce the power of the oil flowing to the exhaust pipe when it flows in the vent chamber in the vertical vent section. By reducing the power of the oil flowing to the exhaust pipe, the amount of oil discharged from the exhaust pipe is reduced, preventing excessive oil from being discharged into the external environment and affecting the external environment.

[0036] (3) By closing the connecting cover at the air inlet pipe, when the air pressure inside the oil storage tank reaches the third pressure pre-value, the oil can flow to the exhaust pipe. At this time, the plug can block the oil, greatly reducing the oil power. The high-pressure gas flows through the air outlet groove into the interior of the first air chamber and breaks open the first pressure-resistant valve plate, and is discharged from the exhaust port. By setting the plug to block the oil, the amount of oil discharged from the exhaust port is reduced, preventing excessive oil from being discharged into the external environment and affecting the external environment.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figures 1-12 As shown, the explosion-proof storage tank of the present invention is characterized by comprising an oil storage tank body 1, a vent pipe 21, a preliminary sealing valve plate 22, a connecting pipe 23, a buffer component 3, an oil filter membrane 41, a buffer pipe 42, and a shock absorber 43. The vent pipe 21 is connected to the top of the oil storage tank body 1. The preliminary sealing valve plate 22 is disposed inside the vent pipe 21 and seals the vent pipe 21; the movable end of the preliminary sealing valve plate 22 is bonded to the vent pipe 21 with silicone sealant. The buffer component 3 is disposed on the oil storage tank body 1 and is connected to the vent pipe 21 via the connecting pipe 23. The connecting pipe 23 and the vent pipe 21 are detachably connected. The interior of the buffer component 3 forms a space for gas flow. The ventilation chamber 31 has an exhaust pipe 35 at the top of the buffer member 3, which is connected to the ventilation chamber 31. The oil filter membrane 41 is a polytetrafluoroethylene microporous membrane, which is set inside the ventilation chamber 31 and divides the ventilation chamber 31 into an air inlet chamber 311 and an air outlet chamber 312. The buffer member 3 has two buffer holes 331, which are connected to the air inlet chamber 311 and the air outlet chamber 312 respectively. The buffer tube 42 is a concave tube, and its two ends are inserted into the two buffer holes 331 respectively and are sealed to the two buffer holes 331 respectively. The shock absorber 43 is set between the buffer tube 42 and the buffer member 3 to prevent the buffer tube 42 from sliding.

[0052] In practice, two initial sealing valve plates 22 are used, and the movable ends of the two initial sealing valve plates 22 are bonded together with silicone sealant. The vent pipe 21 and the connecting pipe 23 are detachably connected via flanges, and the connecting pipe 23 is a rubber hose. A support column is provided at the bottom of the buffer component 3, and the buffer component 3 is fixedly connected to the top of the oil storage tank body 1 via the support column. By setting the oil filter membrane 41 to a polytetrafluoroethylene microporous membrane, the oil filter membrane 41 possesses both oil filtering properties and high air permeability. A sealing ring is provided inside the buffer hole 331 to seal against the buffer pipe 42. A connecting plate is provided outside the buffer pipe 42, and the shock absorber 43 is fixedly connected to the connecting plate.

[0053] By setting the buffer tube 42 to be connected to the buffer member 3 through the shock absorber 43, when the impact on the buffer tube 42 is too great, the shock absorber 43 can buffer the impact on the buffer tube 42 by shocking the buffer tube 42.

[0054] Specifically, when the gas pressure inside the oil storage tank 1 reaches the first pre-set pressure value, the pressure release efficiency of the pressure relief valve of the explosion-proof storage tank 1 cannot meet the release requirements of this gas pressure. At this time, the gas pressure can force open the initial sealing valve plate 22, and the high-pressure gas carries oil into the interior of the connecting pipe 23, and then into the interior of the venting chamber 31 through the connecting pipe 23. During the flow of oil along the venting chamber 31, it will be blocked by the oil filter membrane 41. The high-pressure gas will be discharged from the exhaust pipe 35 through the oil filter membrane 41 or the buffer pipe 42, thus completing the rapid discharge of high-pressure gas. When the gas pressure reaches the second pre-set pressure value, in order to prevent the oil filter membrane 41 from obstructing the flow of oil too much, a buffer pipe 42 is set. The higher gas pressure carries a small amount of oil around the oil filter membrane 41 and flows into the side near the exhaust pipe 35 through the buffer pipe 42. During the flow of oil towards the end near the exhaust pipe 35, the long stroke path can reduce the oil power, thereby reducing the amount of oil discharged from the exhaust pipe 35, and thus reducing the impact of excessive pressure on the oil storage tank 1 and the external environment.

[0055] In a preferred embodiment, the buffer 3 includes an intake vertical section 32, a horizontal section 33, and an exhaust vertical section 34. The intake vertical section 32 and the exhaust vertical section 34 are respectively connected to the two ends of the horizontal section 33 and are perpendicular to the horizontal section 33. The height of the exhaust vertical section 34 is higher than the height of the intake vertical section 32. The connecting pipe 23 is connected to the top of the intake vertical section 32, and the exhaust pipe 35 is connected to the top of the exhaust vertical section 34. The oil filter membrane 41 is disposed inside the horizontal section 33. The width of the ventilation chamber 31 located in the intake vertical section 32 is a, the width of the ventilation chamber 31 located in the horizontal section 33 is b, and the width of the ventilation chamber 31 located in the exhaust vertical section 34 is c. The relationship between a, b, and c is: c > a > b.

[0056] This design allows for a larger space in the ventilation chamber 31 within the vertical venting section 34. Furthermore, by setting the vertical venting section 34 vertically, the oil can be subjected to the maximum influence of gravity as it passes through the vertical venting section 34, thus reducing the oil's dynamics.

[0057] In practice, after the oil flows around the filter oil film 41, it has a relatively long flow path. This longer flow path reduces the power required for the oil to flow to the exhaust pipe 35. By maximizing the width of the venting chamber 31 within the vertical exhaust section 34, the volume of the venting chamber 31 within the vertical exhaust section 34 is maximized. This larger volume further reduces the power required for the oil to flow to the exhaust pipe 35. By reducing the power required for the oil to flow to the exhaust pipe 35, the amount of oil discharged from the exhaust pipe 35 is reduced, preventing excessive oil discharge into the external environment and its impact.

[0058] In a preferred embodiment, a flow guide block 44 is also included. The flow guide block 44 is disposed inside the transverse section 33 and is sealed and fitted to the bottom wall of the venting chamber 31. The top wall of the flow guide block 44 is an inclined wall. The oil filter membrane 41 is sealed and connected to the top wall of the flow guide block 44. One side of the buffer member 3 is connected to two oil drain pipes 36. The two oil drain pipes 36 are respectively connected to both sides of the oil filter membrane 41, and the top wall of the flow guide block 44 extends to the end of the oil drain pipes 36.

[0059] This design allows for the collection of oil stored in the vent chamber 31. Specifically, when collection is needed, the drain pipe 36 can be opened to allow the oil to drain out, thus completing the collection of oil from the vent chamber 31. By providing drain pipes 36 on both sides of the oil filter membrane 41, the two drain pipes 36 can respectively drain oil located on both sides of the oil filter membrane 41. By providing a guide block 44 on the bottom wall of the vent chamber 31, the oil stored inside the vent chamber 31 can be fully discharged through the drain pipes 36.

[0060] In a preferred embodiment, a connecting cover 5 is also included. The connecting cover 5 includes a connecting part 51 and a plug part 52. The connecting part 51 covers the top of the exhaust pipe 35 and is detachably connected to the exhaust pipe 35. The plug part 52 is inserted into the interior of the exhaust pipe 35 and is sealed to the inner wall of the exhaust pipe 35. A first air chamber 521 is provided at the top of the plug part 52. The first air chamber 521 is connected to the periphery of the plug part 52. An air outlet groove 351 is provided on the inner wall of the exhaust pipe 35. The air outlet groove 351 is connected to the first air chamber 521 and the interior of the exhaust pipe 35. An exhaust hole 511 is provided on the connecting part 51 and is connected to the first air chamber 521.

[0061] In practice, the connecting part 51 is connected to the exhaust pipe 35 by bolts. There are two first air chambers 521 and two exhaust holes 511.

[0062] By closing the connecting cover 5 at the air inlet pipe 35, when the air pressure inside the oil storage tank body 1 reaches the third pressure pre-value, the oil can flow to the exhaust pipe 35. At this time, the plug part 52 can block the oil, greatly reducing the oil power. By setting the plug part 52 to block the oil, the amount of oil discharged from the exhaust port 511 is reduced, preventing excessive oil from being discharged into the external environment and affecting the external environment.

[0063] In a preferred embodiment, a first pressure-resistant valve plate 61 is also included, wherein the first pressure-resistant valve plate 61 is disposed on the top of the connecting portion 51, and the movable end of the first pressure-resistant valve plate 61 covers the vent hole 511, and the movable end of the first pressure-resistant valve plate 61 is bonded to the connecting portion 51 by silicone sealant.

[0064] Specifically, after the plug portion 52 blocks the oil, the high-pressure gas flows through the vent groove 351 into the interior of the first air chamber 521 and pushes open the first pressure-resistant valve plate 61, and is discharged from the vent hole 511. During this period, when the air pressure is not high, the first pressure-resistant valve plate 61 can play the role of blocking oil again, preventing oil from being discharged from the connecting cover 5.

[0065] In a preferred embodiment, a second pressure-resistant valve plate 62 is also included, wherein the bottom of the plug portion 52 is conical, and a second air chamber 522 is provided at the bottom of the plug portion 52. An air outlet channel 523 is provided inside the plug portion 52, and the air outlet channel 523 communicates with the first air chamber 521 and the second air chamber 522. Both second pressure-resistant valve plates 62 are disposed inside the second air chamber 522 and block the second air chamber 522. The movable ends of the two second pressure-resistant valve plates 62 are bonded together with epoxy resin adhesive.

[0066] By setting the bottom of the plug part 52 to be conical, the excessive resistance of the plug part 52 to the oil is prevented from damaging the buffer 3. When the gas pressure inside the oil storage tank body 1 reaches the fourth pressure pre-value, the excessive gas pressure can open the second pressure-resistant valve plate 62. At this time, the gas can also be discharged from the second gas chamber 522 into the interior of the first gas chamber 521 through the gas outlet channel 523 and discharged from the exhaust port 511, preventing the gas and oil from being subjected to excessive resistance during the exhaust process and damaging the buffer 3.

[0067] In a preferred embodiment, a support frame 63 is also included. Two support frames 63 are disposed inside the second air chamber 522 to shield the movable end of the second pressure-resistant valve plate 62. The end wall of the support frame 63 is an inclined wall. When the movable end of the second pressure-resistant valve plate 62 rotates, the movable end of the second pressure-resistant valve plate 62 is in contact with the end wall of the support frame 63.

[0068] With this design, when the high-pressure gas breaks open the second pressure-resistant valve plate 62, the support frame 63 can support the movable end of the second pressure-resistant valve plate 62 to prevent the movable end of the second pressure-resistant valve plate 62 from detaching due to large-amplitude shaking.

[0069] As a preferred embodiment, it also includes a metal outer protective net 71, wherein the metal outer protective net 71 is a protective steel net, which is sleeved around the periphery of the oil storage tank body 1, and a grounding cable 72 is connected to the metal outer protective net 71.

[0070] In practice, the metal outer protective net 71 has multiple through holes for the equipment to pass through.

[0071] With this design, when static electricity is generated outside the oil storage tank body 1, the metal outer protective net 71 can guide the static electricity and prevent it from accumulating and causing a fire through the grounding cable 72.

[0072] In a preferred embodiment, a bottom box 81 is also included, wherein an oil inlet pipe 11 and an oil outlet pipe 12 are connected to the oil storage tank body 1; the bottom box 81 is located at the bottom of the oil storage tank body 1, and a water storage cavity 811 is formed inside the bottom box 81, and the bottom box 81 is attached to the outer wall of the oil storage tank body 1; an assembly hole 812 and an assembly groove 813 are provided on the bottom box 81, the assembly hole 812 is connected to the top and bottom of the bottom box 81, the oil outlet pipe 12 passes through the assembly hole 812, the metal outer protective net 71 is located inside the assembly groove 813, and a water inlet pipe 82 and a water outlet pipe 83 are connected to the bottom box 81.

[0073] The bottom tank 81 is a copper water tank.

[0074] By setting the bottom box 81 as a copper water tank, the bottom box 81 has good thermal conductivity. By filling the water storage cavity 811 with water, the bottom box 81 can dissipate heat from the oil storage tank body 1, thereby preventing the oil storage tank body 1 from causing safety hazards due to excessive temperature.

[0075] Preferably, the bottom of the base box 81 is provided with support legs 9, which are used to support the base box 81. By raising the height of the base box 81, the support legs 9 reduce the impact of ground heat sources on the oil storage tank body 1.

[0076] The working principle of this invention is described below:

[0077] When the gas pressure inside the oil storage tank 1 reaches the first pressure pre-value, the higher gas pressure can break through the initial sealing valve plate 22. At this time, the high-pressure gas carries oil into the interior of the connecting pipe 23 and then into the interior of the venting chamber 31. During the flow of oil along the venting chamber 31, it is blocked by the oil filter membrane 41. The high-pressure gas flows into the outlet vertical section 34 through the oil filter membrane 41 or the buffer pipe 42. When the gas pressure reaches the second pressure pre-value, in order to prevent the oil filter membrane 41 from obstructing the flow of oil too much, a buffer pipe 42 is installed. The higher gas pressure carries a small amount of oil around the oil filter membrane 41 and flows into the outlet vertical section 34 through the buffer pipe 42. The oil flowing in the outlet vertical section 34 is affected by its own gravity. The lower pressure can reduce power. When the air pressure reaches the third pressure pre-value, the oil can flow through the vertical air outlet to the connecting cover 5. At this time, the plug part 52 can block the oil, greatly reducing the oil power. The high-pressure gas flows through the air outlet groove 351 into the interior of the first air chamber 521 and opens the first pressure-resistant valve plate 61, and is discharged from the exhaust hole 511. When the air pressure reaches the fourth pressure pre-value, the gas can also open the second pressure-resistant valve plate 62, and be discharged from the second air chamber 522 into the interior of the first air chamber 521 through the air outlet channel 523, and be discharged from the exhaust hole 511. By setting the oil filter film 41 and the plug part 52 to block the oil, excessive oil is prevented from being discharged into the external environment and affecting the external environment.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
