Description

Technical Field

[0001] This utility model relates to the technical field of automatic pressure relief equipment, specifically to an automatic pressure relief device for an organic heat carrier furnace under overpressure. Background Technology

[0002] An organic heat carrier heater is a type of heating equipment that uses coal, oil, or combustible gas as fuel and thermal oil as the heat carrier. The thermal oil is heated and then pumped to the heat-using equipment via a circulating pump before returning to the heater. It is a special type of industrial furnace.

[0003] During operation, organic heat carrier furnaces may experience abnormal pressure increases due to factors such as elevated heat carrier temperature or system blockage, posing an explosion risk. Existing pressure relief devices mostly use mechanical safety valves, but their response speed is slow. Developing an efficient and reliable automatic overpressure relief device is of great significance. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the operation of an organic heat carrier furnace, the pressure inside the furnace may rise abnormally due to factors such as increased heat carrier temperature or system blockage, posing a risk of explosion. Existing pressure relief devices mostly use mechanical safety valves, but their response speed is slow. This invention provides an automatic overpressure relief device for an organic heat carrier furnace, which can preset its pressure range and relieve pressure before it becomes oversaturated, thus avoiding safety problems such as explosions caused by excessive pressure.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an automatic pressure relief device for an organic heat carrier furnace, including a boiler, a control column detachably connected to one side wall of the top of the boiler, a lifting column telescopically connected inside the control column, one end of the lifting column extending into the boiler and fixedly connected to a force-bearing plate, a discharge column detachably connected to one side of the boiler located on the control column, the discharge column communicating with the interior of the boiler, a diffuser plate detachably connected to the end of the discharge column away from the boiler, the top of the diffuser plate having a mesh structure, and fan blades rotatably connected inside.

[0006] As a preferred technical solution of this utility model, controllers are detachably connected to the opposite side walls of the control column, and connecting wires are fixedly connected to one side of each of the two controllers. An inner groove is opened inside the lifting column.

[0007] As a preferred embodiment of this utility model, a spring is fixedly connected to the bottom side wall of the inner groove, a movable rod is telescopically inserted into the inner groove, one end of the movable rod extending into the inner groove is fixedly connected to the top of the spring, and a pressing plate is fixedly connected to the side of the lifting column near the bottom edge.

[0008] As a preferred technical solution of this utility model, a fixing frame is fixedly connected to the side wall opposite to the control column and the discharge column. One end of the fixing frame is detachably embedded with a telescopic rod. The telescopic rod is electrically connected to the controller through a connecting line. The output end of the telescopic rod extends and inserts into the discharge column.

[0009] As a preferred technical solution of this utility model, a semi-circular surrounding ring is fixedly connected to the inner wall of the discharge column. The top of the surrounding ring has an inclined structure and a circular sealing plate is placed close to it. The sealing plate is fixedly connected to the output end of the telescopic rod extending into the discharge column. A temporary storage airbag is fixedly connected to one side of the discharge column near the bottom.

[0010] This invention has the following advantages: When the pressure inside the boiler is too high, it will squeeze the pressure plate, thereby lifting the lifting column upwards. Then, it will drive the movable rod to press the controller at the top, which will activate the telescopic rod, thereby pulling the sealing plate away from the surrounding ring. In this way, the gas pressure inside the boiler will be discharged along the discharge column. As the pressure inside the boiler decreases, the pressure plate will descend, thereby driving the lifting column and the movable rod to descend synchronously. When the movable rod leaves the controller and the pressing plate descends to fit with the controller below, it will drive the telescopic rod to extend until the sealing plate closes to achieve a seal, preventing gas pressure leakage inside the boiler. This method can achieve automatic pressure relief, and because the pressure plate changes in real time according to the pressure changes inside the boiler, it can avoid safety accidents caused by delays.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3This utility model discloses an automatic pressure relief device for an organic heat carrier furnace, comprising a boiler 1, a control column 2 detachably connected to one side wall of the top of the boiler 1, a lifting column 8 telescopically connected inside the control column 2, one end of the lifting column 8 extending into the boiler 1 and fixedly connected to a force-bearing plate 10, a discharge column 6 detachably connected to one side of the boiler 1 located on the control column 2, the discharge column 6 communicating with the interior of the boiler 1, a diffuser plate 7 detachably connected to the end of the discharge column 6 away from the boiler 1, the top of the diffuser plate 7 having a mesh structure, and fan blades rotatably connected inside;

[0017] Controllers 11 are detachably connected to the opposite side walls of the control column 2. Connecting wires 5 are fixedly connected to one side of each controller 11. An inner groove 15 is opened inside the lifting column 8. A spring 16 is fixedly connected to the bottom side wall of the inner groove 15. A movable rod 9 is telescopically inserted into the inner groove 15. One end of the movable rod 9 extending into the inner groove 15 is fixedly connected to the top of the spring 16. A pressing plate 12 is fixedly connected to the side of the lifting column 8 near the bottom edge. A fixing frame 3 is fixedly connected to the side wall opposite to the discharge column 6 of the control column 2. A telescopic rod 4 is detachably embedded at one end of the fixing frame 3. The telescopic rod 4 is electrically connected to the controller 11 through the connecting wire 5. The output end of the telescopic rod 4 extends and inserts into the discharge column 6.

[0018] The technical effect of this solution is as follows: The force plate 10 located inside the boiler 1 will change position according to the pressure changes inside the boiler 1. When the pressure increases, the force plate 10 will be squeezed out, which will drive the lifting column 8 to rise outward, thereby driving the lifting column 8 and the movable rod 9 to rise synchronously. When the movable rod 9 is in contact with the controller 11 above, the telescopic rod 4 will be activated to drive the sealing plate away from the surrounding ring 13. In this way, the air pressure inside the boiler 1 will be discharged through the diffuser plate 7 along the discharge column 6, avoiding safety problems such as explosion caused by excessive pressure inside the boiler 1. As the pressure decreases, the lifting column 8 will bring the pressing plate 12 down. When the pressing plate 12 is about to be in contact with the controller 11 below, the telescopic rod 4 will be activated to push the sealing plate back to its original position, realizing the sealing of the discharge column 6 and ensuring the smooth operation of the boiler 1.

[0019] A semi-circular surrounding ring 13 is fixedly connected to the inner wall of the discharge column 6. The top of the surrounding ring 13 is inclined and a circular sealing plate is placed close to it. The sealing plate is fixedly connected to the output end of the telescopic rod 4 that extends into the discharge column 6. A temporary storage airbag 14 is fixedly connected to one side of the discharge column 6 near the bottom.

[0020] The technical effect of this solution is as follows: a temporary air bladder 14 is fixed on one side of the discharge column 6, which can initially collect the overflowing air pressure when the pressure inside the boiler 1 is too high, providing a buffer time for subsequent pressure relief and improving safety. The fan blades inside the diffuser plate 7 will rotate when impacted by the air pressure, which can diffuse the pressure and prevent the pressure from rushing out in a straight line and causing safety problems to the staff.

[0021] Specifically, when this utility model is used, as the pressure inside the boiler 1 increases, the force plate 10 located inside the boiler 1 will be squeezed outward by the pressure. As the force plate 10 moves, it will drive the lifting column 8 fixed to it to move synchronously. As the lifting column 8 moves, it will drive the movable rod 9 to rise synchronously. Finally, the movable rod 9 will press against the controller 11, which will control the telescopic rod 4 to retract, thereby driving the sealing plate to move away from the temporary air bag 14, so that the air pressure inside the boiler 1 will be discharged outward from the discharge column 6, thereby reducing the pressure inside the boiler 1. As the pressure decreases, the lifting column 8 will descend under the pull of the force plate 10, but the movable rod 9 will continue to press against the controller 11 under the support of the spring 16 until the spring 16 is fully opened during the descent of the lifting column 8 and the movable rod 9 will follow and descend. Although the movable rod 9 leaves the controller 11, the telescopic rod 4 will not extend.

[0022] As the lifting column 8 descends, it causes the pressing plate 12 to contact the controller 11 below. Only then will the telescopic rod 4 be controlled to extend and drive the sealing plate to adhere to the surrounding ring 13 to achieve sealing and prevent air pressure leakage. During the above-mentioned movement process, sufficient time can be allowed for pressure relief to ensure that the pressure drops to a safe range. Furthermore, the counterweight of the force plate 10 and its position inside the boiler 1 can be adjusted according to the actual situation to achieve pressure relief before the pressure is too high but exceeds the limit, thereby improving safety.

[0023] The temporary airbag 14 fixed on the discharge column 6 can increase the pressure-accommodating space, thereby providing a buffer time for depressurization and reducing the risk of explosion caused by excessive pressure not being dealt with in time.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
