Description

Technical Field

[0001] This utility model belongs to the field of oil tank technology, specifically a high-strength leak-proof double-walled oil tank. Background Technology

[0002] High-strength double-walled oil tanks are specially designed and constructed oil storage containers, characterized by high safety, long service life, environmental friendliness, and high efficiency. They consist of two independent inner and outer tanks. The outer tank is typically made of high-strength materials such as carbon steel or stainless steel, while the inner tank uses special leak-proof materials, such as fiberglass or polymer synthetic materials. The space between the two tanks is usually filled with inert gas or polyurethane foam to achieve leak-proof and insulation effects. High-strength double-walled oil tanks have wide applications in the petroleum, chemical, agricultural, and wastewater treatment industries. However, existing high-strength double-walled oil tanks suffer from poor sealing at the outlet connection to pipelines, easily leading to media leakage and resulting in unsatisfactory performance. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a high-strength leak-proof double-walled oil tank, which effectively solves the problem of poor sealing when the oil outlet of the existing high-strength double-walled oil tank is connected to the pipeline, which easily causes media leakage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength leak-proof double-walled oil tank, comprising a support frame, a high-strength double-walled oil tank body fixedly mounted on the top of the support frame, an oil inlet valve fixedly mounted on one side of the top of the high-strength double-walled oil tank body, an oil outlet fixedly mounted in the middle of the bottom of the high-strength double-walled oil tank body, an equipment box fixedly mounted on the lower rear of the high-strength double-walled oil tank body, a handwheel provided on one side of the equipment box, an air bladder fixedly mounted on the bottom of the equipment box, an air pipe fixedly mounted on the bottom of the air bladder via an air nozzle, an installation groove provided on the inner wall of the oil outlet, a hollow sealing ring fixedly mounted inside the installation groove, a sealing gasket fixedly mounted on the inner top of the high-strength double-walled oil tank body, one end of the air pipe extending into the interior of the installation groove and fixedly connected to the hollow sealing ring, a transmission component provided on one side of the handwheel, a pressure plate provided in the middle of the equipment box, the transmission component being connected to the pressure plate, and when the handwheel rotates, power is output to the pressure plate through the transmission component, causing the pressure plate to move and compress the air bladder.

[0005] Preferably, the transmission assembly includes a shaft, which is fixedly installed on one side of the handwheel. A bushing is rotatably installed on the surface of the shaft, and the bushing is fixedly installed on one side of the equipment box. One end of the shaft extends into the interior of the equipment box and is fixedly installed with a rotating bar. A transmission pin is rotatably installed on the upper part of one side of the rotating bar. A moving bar is sleeved on the surface of the transmission pin. A moving rod is fixedly installed at the bottom of the moving bar, and the bottom of the moving rod is fixedly connected to the top of the pressure plate.

[0006] Preferably, limit blocks are fixedly installed at both ends of the moving strip, and limit grooves are opened on the inner walls of both ends of the equipment box. The two limit blocks are slidably installed inside the two limit grooves. Slider blocks are fixedly installed on both sides of the pressure plate, and sliding grooves are opened on the inner walls of both sides of the equipment box. The two sliders are slidably installed inside the two sliding grooves.

[0007] Preferably, a rod is movably inserted into the surface of the handwheel, a baffle is fixedly installed at the end of the rod surface, a spring is provided in the middle of the rod surface, and both ends of the spring are fixedly connected to the baffle and the handwheel respectively. A groove is provided on the side of the equipment box away from the oil outlet, and two slots are provided inside the groove. One end of the rod is inserted into the inside of one of the slots.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator inserts the pipe into the oil outlet and presses it against the sealing gasket. Then, the operator pulls the insertion rod to move it. When the insertion rod is inserted, it will disengage from one of the slots and release the limit. At the same time, the spring is compressed by the baffle plate. Then, the operator rotates the handwheel. When the handwheel rotates, it drives the shaft to rotate inside the bushing. When the shaft rotates, it drives the transmission pin to rotate through the rotating bar. When the transmission pin rotates, it drives the moving bar to move down. When the moving bar moves, it drives the slider to slide along the inside of the slide groove, which increases the stability of the moving bar. When the moving bar moves down, it drives the pressure plate to move down through the moving rod. When the pressure plate moves, it drives the two limit blocks to slide along the inside of the two limit grooves, which increases the stability of the pressure plate.

[0009] When the pressure plate moves down, it compresses the air bladder, forcing the air inside the bladder through the air nozzle and air pipe into the hollow sealing ring, causing the hollow sealing ring to expand and thus improving the sealing effect between the pipeline and the oil outlet. As the pressure plate moves to the bottom, the insertion rod moves along the ring groove to another slot. Then, the operator releases the insertion rod, and under the elastic force of the spring, the insertion rod is pushed into the other slot for self-locking. This ensures that the oil outlet of this high-strength double-walled oil tank has a good sealing effect at the connection with the pipeline, preventing media leakage and providing excellent performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 7The present invention includes a support frame 1, a high-strength double-walled oil tank body 3 fixedly mounted on the top of the support frame 1, an oil inlet valve 4 fixedly mounted on one side of the top of the high-strength double-walled oil tank body 3, an oil outlet 5 fixedly mounted on the middle of the bottom of the high-strength double-walled oil tank body 3, an equipment box 6 fixedly mounted on the lower rear of the high-strength double-walled oil tank body 3, a handwheel 7 provided on one side of the equipment box 6, an air bladder 8 fixedly mounted on the bottom of the inside of the equipment box 6, and an air pipe 10 fixedly mounted on the bottom of the air bladder 8 through an air nozzle 9. The oil outlet 5... The inner wall of the tank has an installation groove 11, and a hollow sealing ring 12 is fixedly installed inside the installation groove 11. A sealing gasket 13 is fixedly installed on the inner top of the high-strength double-layer oil tank body 3. One end of the air pipe 10 extends into the interior of the installation groove 11 and is fixedly connected to the hollow sealing ring 12. A transmission component is provided on one side of the handwheel 7. A pressure plate 28 is provided in the middle of the equipment box 6. The transmission component is connected to the pressure plate 28. When the handwheel 7 rotates, the power is output to the pressure plate 28 through the transmission component, so that the pressure plate 28 moves to squeeze the air bag 8.

[0022] During use, the operator inserts the pipe into the oil outlet 5 and presses it against the sealing gasket 13. Then, the operator unlocks the handwheel 7 and rotates it to adjust the transmission component. When the transmission component is running, it drives the pressure plate 28 to move down. When the pressure plate 28 moves down, it squeezes the air bladder 8, thereby forcing the air inside the air bladder 8 into the hollow sealing ring 12 through the air nozzle 9 and air pipe 10. This causes the hollow sealing ring 12 to expand, thereby improving the sealing effect between the pipe and the oil outlet 5. At the same time, the handwheel 7 will self-lock to ensure that the handwheel 7 will not rotate. This ensures that the oil outlet 5 of this high-strength double-walled oil tank has a good sealing effect at the connection with the pipe, preventing leakage of the medium and providing excellent performance.

[0023] The transmission assembly includes a shaft 14, which is fixedly mounted on one side of the handwheel 7. A bushing 15 is rotatably mounted on the surface of the shaft 14, and the bushing 15 is fixedly mounted on one side of the equipment housing 6. One end of the shaft 14 extends into the interior of the equipment housing 6 and is fixedly mounted with a rotating bar 22. A transmission pin 23 is rotatably mounted on the upper part of one side of the rotating bar 22. A moving bar 24 is sleeved on the surface of the transmission pin 23. A moving rod 27 is fixedly mounted on the bottom of the moving bar 24, and the bottom of the moving rod 27 is fixedly connected to the top of the pressure plate 28. Limit blocks 25 are fixedly mounted on both ends of the moving bar 24, and limit grooves 26 are formed on the inner walls of both ends of the equipment housing 6. Position block 25 is slidably installed inside the two limiting grooves 26. Slider 17 is fixedly installed on both sides of pressure plate 28. Slide grooves 2 are opened on both sides of the inner wall of equipment box 6. The two sliders 17 are slidably installed inside the two slide grooves 2. A plug rod 16 is movably inserted into the surface of handwheel 7. A baffle 18 is fixedly installed at the end of the surface of plug rod 16. A spring 19 is provided in the middle of the surface of plug rod 16. Both ends of spring 19 are fixedly connected to baffle 18 and handwheel 7 respectively. A ring groove 20 is opened on the side of equipment box 6 away from oil outlet 5. Two slots 21 are opened inside the ring groove 20. One end of plug rod 16 is inserted into the inside of one of the slots 21.

[0024] When the operator pulls the insertion rod 16, it will disengage from one of the slots 21 and release the limit. At the same time, the spring 19 will be compressed by the baffle 18. Then the operator rotates the handwheel 7. When the handwheel 7 rotates, it drives the shaft 14 to rotate inside the bushing 15. When the shaft 14 rotates, it drives the transmission pin 23 to rotate through the rotating bar 22. When the transmission pin 23 rotates, it drives the moving bar 24 to move down. When the moving bar 24 moves, it drives the slider 25 to slide along the inside of the slide groove 26, which increases the stability of the moving bar 24. When the moving bar 24 moves down, it drives the pressure plate 28 to move down through the moving rod 27. When the pressure plate 28 moves, it drives the two limit blocks 17 to slide along the inside of the two limit grooves 2, which increases the stability of the pressure plate 28. When the pressure plate 28 moves down, it will compress the airbag 8.

[0025] As the pressure plate 28 is moved to the bottom, the insertion rod 16 will move along the groove 20 to another slot 21. Then the operator releases the insertion rod 16, and under the elastic force of the spring 19, the insertion rod 16 will be pushed into the interior of the other slot 21 for self-locking.
