Description

Technical Field

[0001] This utility model relates to the field of pressure vessel technology, and in particular to a boiler pressure vessel with a leak-proof structure. Background Technology

[0002] Boilers and pressure vessels are indispensable pieces of equipment in industrial production, widely used in energy, chemical, pharmaceutical, and other fields. However, due to the special nature of their working environment, boilers and pressure vessels face many challenges during operation, one of the most critical issues being how to ensure sealing performance and prevent media leakage.

[0003] Traditional boiler pressure vessels have numerous shortcomings in their sealing structure design. For example, some equipment uses simple gasket seals or threaded seals, which are prone to aging and deformation under prolonged high temperature and pressure, leading to decreased sealing performance and subsequent media leakage. Furthermore, traditional boiler pressure vessels also have limitations in their limit mechanism design. The fixing method between the top cover and the tank body of some equipment is not secure enough, and it is easily loosened or even detached due to media pressure or external factors, further increasing the risk of leakage.

[0004] Against this backdrop, this utility model proposes a boiler pressure vessel with a leak-proof structure. Utility Model Content

[0005] This utility model discloses a boiler pressure vessel with a leak-proof structure. By optimizing the sealing structure, designing a convenient limiting mechanism, and adding a safety monitoring device, the sealing performance, stability, and safety of the boiler pressure vessel are effectively improved, resulting in significant benefits.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A boiler pressure vessel with a leak-proof structure includes a pressure tank, a top cover is installed on the top of the pressure tank, and a limiting mechanism is provided on the surface of both the pressure tank and the top cover, the limiting mechanism being used to limit the top cover.

[0008] The pressure tank is equipped with a sealing assembly, which includes several limiting air holes formed on the inner wall of the pressure tank. Sliding columns are slidably arranged on the inner wall of the limiting air holes. One end of each sliding column extends to the outside of the pressure tank and is fixedly connected to a movable sealing ring. A limiting fixing ring is fixedly arranged on the top edge of the pressure tank. An annular sealing groove is formed on the upper surface of the limiting fixing ring. The position of the movable sealing ring corresponds to the annular sealing groove. A positioning sealing ring is fixedly connected to the lower surface of the top cover. The positioning sealing ring is inserted into the annular sealing groove. Several limiting protrusions are fixedly connected to the surface of the movable sealing ring. Several limiting grooves are formed on the inner side of the positioning sealing ring.

[0009] In a preferred embodiment, the outer ring surface of the movable sealing ring abuts against the inner ring surface of the positioning sealing ring, the size of the limiting groove matches the limiting protrusion, and the limiting protrusion is inserted into the limiting groove.

[0010] In a preferred embodiment, the limiting mechanism includes two limiting fixing frames fixedly connected to the surface of the pressure tank. A limiting screw is rotatably connected inside the limiting fixing frame. A moving block is threadedly connected to the surface of the limiting screw. An extension rod is fixedly connected to the top of the moving block.

[0011] In a preferred embodiment, a limiting rubber roller is rotatably provided at the end of the extension rod. The limiting mechanism further includes two limiting mounting blocks fixedly connected to the surface of the top cover. A trapezoidal groove is provided on the side of the limiting mounting block. The position of the trapezoidal groove corresponds to the limiting rubber roller, and the size of the trapezoidal groove matches the limiting rubber roller. The limiting rubber roller overlaps with the inner wall of the trapezoidal groove.

[0012] In a preferred embodiment, a reinforcing support plate is fixedly connected to the surface of the limiting mounting block, and the bottom end of the reinforcing support plate is fixedly connected to the upper surface of the top cover.

[0013] In a preferred embodiment, the end of the limiting screw extends to the outside of the limiting fixing frame, and an operating handle is fixedly provided at the end of the limiting screw.

[0014] In a preferred embodiment, an exhaust pipe and a pressure relief pipe are fixedly provided on the upper surface of the top cover. An exhaust switch valve is provided on the surface of the exhaust pipe, a pressure relief valve and a pressure sensor are fixedly provided on the surface of the pressure relief pipe, and an audible and visual alarm is fixedly provided on the surface of the pressure sensor.

[0015] As can be seen from the above, the boiler pressure vessel with a leak-proof structure provided by this utility model has the following technical effects.

[0016] Firstly, this invention achieves multiple seals between the top cover and the pressure vessel by incorporating a sealing assembly, including a limiting vent, a sliding column, a movable sealing ring, a limiting fixing ring, an annular sealing groove, a positioning sealing ring, a limiting protrusion, and a limiting groove. Under the pressure of the gas inside the pressure vessel, the sliding column moves outward, causing the movable sealing ring to expand outward. The tight overlap between the movable sealing ring and the positioning sealing ring, along with the insertion and engagement of the limiting protrusion and the limiting groove, significantly enhances the reliability and stability of the seal, effectively preventing media leakage and ensuring the safe operation of the boiler pressure vessel.

[0017] Secondly, the design of the limiting mechanism, including components such as a limiting fixing frame, limiting screw, moving block, extension rod, limiting rubber roller, limiting mounting block, trapezoidal slot, reinforcing support plate, and operating handle, makes the limiting and fixing of the top cover simple and quick. By rotating the operating handle, the limiting screw can be driven to rotate, which in turn moves the moving block and extension rod, allowing the limiting rubber roller to tightly engage with the trapezoidal slot, thereby achieving a stable limiting of the top cover. This limiting mechanism is not only easy to operate but also has a reliable limiting effect, improving the overall stability of the boiler pressure vessel. Attached Figure Description

[0027] 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.

[0028] Reference Figures 1-6 This utility model discloses a boiler pressure vessel with a leak-proof structure, mainly comprising a pressure tank 1, a top cover 2, a limiting mechanism 3, a sealing assembly 4, and other auxiliary components. These components work together to ensure the safe, stable, and efficient operation of the boiler pressure vessel.

[0029] By incorporating pressure tank 1 as the main body of the boiler pressure vessel, pressure tank 1 is made of high-strength material and can withstand working environments under high temperature and high pressure. Its interior includes a cavity for containing the medium and a structure for installing other components.

[0030] A top cover 2 is installed on top of the pressure tank 1 to seal the opening of the pressure tank 1. The top cover 2 is equipped with an exhaust pipe 5 and a pressure relief pipe 6 to discharge the medium or release pressure when needed.

[0031] It is worth noting that a limiting mechanism 3 is provided, which is installed on the surfaces of the pressure tank 1 and the top cover 2, to limit and fix the top cover 2. Through the function of the limiting mechanism 3, the top cover 2 can be securely installed on the pressure tank 1, preventing it from falling off due to medium pressure or external factors.

[0032] It is worth noting that the sealing component 4 is the core part of this invention, used to achieve a seal between the top cover 2 and the pressure tank 1. By optimizing the sealing structure, the sealing performance of the boiler pressure vessel can be greatly improved, preventing media leakage.

[0033] It should be further explained that the sealing assembly 4 includes components such as a limiting air hole 401, a sliding column 402, a movable sealing ring 403, a limiting fixing ring 404, an annular sealing groove 405, a positioning sealing ring 406, a limiting protrusion 407, and a limiting groove 408.

[0034] It should be noted that the limiting vent 401 is formed on the inner wall of the pressure tank 1 for installing the sliding column 402. The number and position of the limiting vent 401 are determined according to actual needs to ensure the reliability and stability of the sealing assembly 4.

[0035] It should be noted that the sliding column 402 is slidably disposed in the inner wall of the limiting vent 401, with one end extending to the outside of the pressure tank 1 and fixedly connected to the movable sealing ring 403. Through the action of the sliding column 402, the movable sealing ring 403 can be moved and adjusted inside the pressure tank 1, and the limiting vent 401 can be driven to move by the high-pressure gas inside the pressure tank 1.

[0036] It should be noted that the movable sealing ring 403 is one of the key components of the sealing assembly 4, and its outer ring surface abuts against the inner ring surface of the positioning sealing ring 406. When the top cover 2 is installed on the pressure tank 1, the movable sealing ring 403 is subjected to pressure and presses tightly against the positioning sealing ring 406, forming a tight sealing barrier. At the same time, several limiting protrusions 407 are also fixedly connected to the surface of the movable sealing ring 403. These limiting protrusions 407 can be inserted into the limiting grooves 408 inside the positioning sealing ring 406, further enhancing the sealing effect.

[0037] It should be noted that the limiting and fixing ring 404 is fixedly installed on the top edge of the pressure tank 1, and an annular sealing groove 405 is formed on its upper surface. The shape and size of the annular sealing groove 405 match the positioning sealing ring 406, and it is used to accommodate and fix the positioning sealing ring 406.

[0038] The positioning sealing ring 406 is fixedly connected to the lower surface of the top cover 2 and is inserted into the annular sealing groove 405. The inner side of the positioning sealing ring 406 has several limiting grooves 408, which are used to cooperate with the limiting protrusions 407 on the surface of the movable sealing ring 403 to achieve a tighter sealing effect.

[0039] It is worth noting that the limiting mechanism 3 includes components such as a limiting fixing frame 301, a limiting screw 302, a moving block 303, an extension rod 304, a limiting rubber roller 305, a limiting mounting block 306, a trapezoidal slot 307, a reinforcing support plate 308, and an operating handle 309.

[0040] The limiting and fixing frame 301 is fixedly connected to the surface of the pressure tank 1 and is used to install the limiting screw 302. The number and position of the limiting and fixing frames 301 are determined according to actual needs to ensure the reliability and stability of the limiting mechanism 3.

[0041] It should be noted that the limiting screw 302 is rotatably connected inside the limiting fixing frame 301, and a moving block 303 is threadedly connected to its surface. By rotating the limiting screw 302, the moving block 303 can be driven to move on the limiting screw 302.

[0042] The movable block 303 is threadedly connected to the limiting screw 302, and an extension rod 304 is fixedly connected to its top. When the movable block 303 moves on the limiting screw 302, the extension rod 304 will also move accordingly.

[0043] It should be noted that a limiting rubber roller 305 is rotatably mounted at the end of the extension rod 304 to cooperate with the trapezoidal groove 307. By adjusting the position and angle of the extension rod 304, the limiting rubber roller 305 and the trapezoidal groove 307 can be tightly engaged.

[0044] It is worth noting that the limiting rubber roller 305 is rotatably mounted at the end of the extension rod 304, and its material is elastic material such as rubber. The limiting rubber roller 305 can fit tightly against the inner wall of the trapezoidal groove 307 to form a stable limiting barrier.

[0045] It should be noted that the limiting mounting block 306 is fixedly connected to the surface of the top cover 2, and a trapezoidal groove 307 is provided on its side. The position of the trapezoidal groove 307 corresponds to that of the limiting rubber roller 305, and its size and shape match those of the limiting rubber roller 305. When the top cover 2 is installed on the pressure tank 1, the limiting rubber roller 305 can be inserted into the trapezoidal groove 307 and tightly overlap with the inner wall of the trapezoidal groove 307.

[0046] It is worth noting that the trapezoidal groove 307 is formed on the side of the limiting mounting block 306 and is used to mate with the limiting rubber roller 305. The shape and size of the trapezoidal groove 307 are determined according to the shape and size of the limiting rubber roller 305 to ensure a tight fit between the two.

[0047] It should be noted that the reinforcing support plate 308 is fixedly connected to the surface of the limiting mounting block 306, and its bottom end is fixedly connected to the upper surface of the top cover 2. The function of the reinforcing support plate 308 is to provide additional support and fixation for the limiting mounting block 306 to enhance its stability and reliability.

[0048] The operating handle 309 is fixedly installed at the end of the limiting screw 302, making it convenient for the operator to rotate the limiting screw 302. By rotating the operating handle 309, the positions of the moving block 303 and the extension rod 304 can be easily adjusted, thereby achieving a tight overlap between the limiting rubber roller 305 and the trapezoidal groove 307.

[0049] In addition to the main components mentioned above, the boiler pressure vessel of this utility model also includes auxiliary components such as an exhaust pipe 5, a pressure relief pipe 6, a pressure relief valve 7, a pressure sensor 8, and an audible and visual alarm 9.

[0050] The exhaust pipe 5 is fixedly installed on the upper surface of the top cover 2 and is used to discharge the medium inside the boiler pressure vessel. The surface of the exhaust pipe 5 is equipped with an exhaust switch valve 10 for controlling the discharge of the medium.

[0051] The pressure relief pipe 6 is also fixedly installed on the upper surface of the top cover 2, and is used to release pressure when the pressure inside the boiler pressure vessel is too high. The surface of the pressure relief pipe 6 is equipped with a pressure relief valve 7, which will automatically open to release pressure when the pressure reaches the set value.

[0052] Pressure relief valve 7 is a safety valve used to automatically open when the internal pressure of the boiler pressure vessel exceeds a set value, releasing pressure to protect the equipment.

[0053] Pressure sensor 8 is fixedly installed on the surface of pressure relief pipe 6 to monitor pressure changes inside the boiler pressure vessel in real time. When the pressure exceeds the set value, pressure sensor 8 will send a signal to trigger audible and visual alarm 9.

[0054] The audible and visual alarm 9 is fixedly installed on the surface of the pressure sensor 8. When it receives a signal from the pressure sensor 8, it will emit an audible and visual alarm signal to remind the operator to take timely measures to deal with the abnormal situation.

[0055] When using the boiler pressure vessel of this invention, the top cover 2 must first be installed on the pressure tank 1. By rotating the operating handle 309, the limiting screw 302 is driven to rotate, which in turn drives the moving block 303 and the extension rod 304 to move. When the limiting rubber roller 305 at the end of the extension rod 304 tightly overlaps with the trapezoidal groove 307, the top cover 2 is securely fixed on the pressure tank 1. At this time, the tight overlap between the movable sealing ring 403 and the positioning sealing ring 406, and the insertion and engagement of the limiting protrusion 407 and the limiting groove 408, together form a tight sealing barrier, effectively preventing media leakage.

[0056] During the operation of the boiler pressure vessel, pressure sensor 8 monitors internal pressure changes in real time. Once the pressure exceeds the set value, pressure relief valve 7 automatically opens to release pressure, and simultaneously, audible and visual alarm 9 issues an alarm signal to remind operators to take timely measures to handle the abnormal situation. The installation of these safety monitoring devices greatly improves the safety and reliability of the boiler pressure vessel.

[0057] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
