Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a high-temperature heat dissipation mechanical seal device. Background Technology

[0002] With the rapid development of modern science and technology and industry, equipment in the fields of energy, chemical industry, and metallurgy is constantly breaking through the limits of high temperature, high pressure, and high load. Key devices such as high-temperature and high-pressure pumps (e.g., main steam pumps) in thermal and nuclear power plants, bottom pumps of distillation towers in petrochemicals, and circulating equipment in metallurgical furnaces often operate at medium temperatures as high as 300-600℃, even reaching the heat resistance limit of materials. As a result, high-temperature heat dissipation mechanical seal devices have emerged.

[0003] The device uses a cooling circulation system to remove heat. For example, a jacketed cooling chamber introduces cooling water and reduces the temperature of the sealed cavity through forced convection. Spiral channel cooling uses spiral grooves machined inside the sealing ring to guide the flow of coolant and increase the heat dissipation area. In addition, heat conduction enhancement structures (such as metal bellows and thermal pads) utilize the properties of highly thermally conductive materials to quickly dissipate heat from the sealing surface. The dynamic ring and stationary ring fit tightly together to form the main sealing surface, preventing leakage of high-temperature media. The sealing ring is made of high-temperature and wear-resistant materials such as silicon carbide and tungsten carbide to ensure that the sealing surface still has good flatness and smoothness at high temperatures. The auxiliary sealing structure (such as a flexible graphite ring) maintains elasticity in high-temperature environments, fills the dynamic and static gaps, and prevents media leakage.

[0004] Currently, high-temperature heat dissipation mechanical seals provide an effective solution for high-temperature sealing and heat dissipation in industrial equipment. However, their application faces a contradiction between customization and versatility. The operating parameters (such as temperature, medium, shaft diameter, and space) of machinery in different industries vary significantly. For example, nuclear power plant main pumps need to withstand temperatures of 600℃ and radiation, while chemical reactor seals need to consider corrosion and vibration. This leads to the need for targeted design of the devices, making standardized mass production difficult and resulting in low cross-equipment reuse rates, which increases the procurement and maintenance costs for enterprises. The complex performance requirements under extreme operating conditions (such as high temperature + high pressure + particulate media) further exacerbate the complexity of adaptation. Therefore, high-temperature heat dissipation mechanical seals are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-temperature heat dissipation mechanical seal device, which aims to improve the problem of low cross-equipment reuse rate in the prior art.

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

[0007] A high-temperature heat dissipation mechanical seal device includes a housing, with a chassis fixedly connected to both sides of the housing. An outer shell is fixedly connected to the inner wall of the chassis. Three studs are threadedly connected to the inside of the outer shell. A clamping block is fixedly connected to the side of the three studs that are close to each other. An anti-slip groove is provided on the other side of the clamping block. A rotating disk is fixedly connected to the side of the three studs that are far apart from each other. A slot is opened on the inner wall of the outer shell. A sealing ring is fixedly connected to the inner wall of the slot. Multiple cooling components are slidably connected inside the housing.

[0008] As a further description of the above technical solution:

[0009] The cooling component includes a condenser plate, the outer wall of which is slidably connected to the inner wall of the housing, a groove is provided on the top of the condenser plate, a plurality of limiting posts are slidably connected to the inner wall of the housing, a protrusion is fixedly connected to the outer wall of the limiting post, a retaining ball is fixedly connected to the top of the limiting post, and a spring is sleeved on the outer wall of the limiting post.

[0010] As a further description of the above technical solution:

[0011] The bottom of the sealing ring is fixedly connected to one side of the chassis, and the cross-sectional shape of the rotating disk is hexagonal;

[0012] As a further description of the above technical solution:

[0013] The top of the spring is fixedly connected to the inner wall of the housing, and the bottom of the spring is fixedly connected to the top of the protrusion.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the protrusion is slidably connected to the inner wall of the housing, and the outer wall of the ball contacts the top of the housing;

[0016] As a further description of the above technical solution:

[0017] The outer wall of the limiting post is slidably connected to the inner wall of the groove, and the cross-sectional shape of the protrusion is annular.

[0018] As a further description of the above technical solution:

[0019] One side of the clamping block is in contact with the inner wall of the outer shell, and the cross-sectional shape of the clamping block is arc-shaped;

[0020] As a further description of the above technical solution:

[0021] The sealing ring is circular in shape, and the outer shell is circular in shape.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by rotating the rotating disk, the stud is driven to rotate, thereby adjusting the position of the stud on the inner wall of the outer shell. The space formed by the three clamping blocks can be flexibly changed, so that the interface specifications can be flexibly adjusted according to the heat dissipation needs of different mechanical operations. This allows the heat dissipation device to adapt to the interface size and shape of various equipment, greatly improving the cross-equipment reuse rate. In particular, the setting of the sealing ring is crucial. It is made of high temperature resistant flexible material. When the machinery and the heat dissipation device are connected, the sealing ring will undergo elastic deformation due to compression, tightly filling the connection gap. It can resist the corrosion of high temperature media and prevent coolant leakage. While achieving reliable sealing, it ensures the stable operation of the heat dissipation system, making the device more adaptable and practical in industrial scenarios.

[0024] 2. In this utility model, when the heat dissipation effect of the condenser plate decreases after the heat dissipation device is running, pulling the retaining ball causes the protrusion to compress the spring, releasing the restriction on the condenser plate for replacement. After replacement, pulling the retaining ball again and sliding the condenser plate back to its original position, releasing the retaining ball, the spring releases its elastic potential energy, pushing the protrusion to engage the limiting post with the groove, thus completing the fixation. This elastic limiting structure allows for quick disassembly and assembly of the condenser plate, and allows for replacement of faulty parts without tools, preventing overheating of the equipment due to reduced heat dissipation efficiency, ensuring continuous and efficient operation of the heat dissipation device, and improving the continuous operation capability of industrial equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2 to 4 This utility model provides an embodiment of a high-temperature heat dissipation mechanical seal device, comprising a housing 1. The housing 1 serves as the main frame of the device and is made of high-strength heat-resistant material, capable of resisting the erosion of high-temperature environments and providing a stable protective space for internal components. A base 2 is fixedly connected to both sides of the housing 1, serving as a support and fixation mechanism, providing a stable installation foundation for the entire device and ensuring its stability during mechanical operation, preventing shaking. An outer shell 3 is fixedly connected to the inner wall of the base 2, tightly connected to the base 2, further enhancing the structural strength of the device. Three studs 4 are threadedly connected to the inside of the outer shell 3, allowing for flexible adjustment of their position within the outer shell 3, enabling adaptation to different specifications of equipment. Clamping blocks 6 are fixedly connected to the adjacent sides of the three studs 4, the arc-shaped design of which better conforms to the clamped parts. On the surface of the holding device, the other side of the clamping block 6 is provided with an anti-slip groove 7. The anti-slip groove 7 can effectively increase the friction with the surface of the device, and even under complex working conditions such as high temperature and vibration, it can ensure that the device is stable and will not fall off. The three studs 4 are fixedly connected to the rotating disk 5 on the far side. By rotating the rotating disk 5, the studs 4 can be rotated, thereby adjusting the position of the clamping block 6. The inner wall of the outer shell 3 is provided with a slot 9. The inner wall of the slot 9 is fixedly connected with a sealing ring 8. The slot 9 is used to fix the sealing ring 8. Its shape and size are precisely matched with the sealing ring 8 to ensure that the sealing ring 8 can fit tightly after installation and play a good sealing role. The sealing ring 8 is made of high temperature resistant and wear resistant sealing material, which can form a reliable seal when mechanically docking with the heat dissipation device, preventing coolant leakage or external impurities from entering, and ensuring the normal operation of the heat dissipation system. Multiple cooling components are slidably connected inside the shell 1.

[0033] The cooling component is the core part of the device's heat dissipation function, effectively reducing the high temperatures generated during equipment operation and ensuring normal mechanical operation. The cooling component includes a condenser plate 10, which has high thermal conductivity and cooling performance. The outer wall of the condenser plate 10 is slidably connected to the inner wall of the housing 1, facilitating installation and disassembly. During heat dissipation, it can quickly absorb and dissipate heat. A groove 11 is provided on the top of the condenser plate 10. Multiple limiting posts 12 are slidably connected to the inner wall of the housing 1, allowing the limiting posts 12 to slide within the housing 1 and engage with the groove 11. The condenser plate 10 can be locked or unlocked by opening or closing the condenser plate 10. The operation is convenient and quick. The outer wall of the limiting post 12 is fixedly connected with a protrusion 13, and the top of the limiting post 12 is fixedly connected with a retaining ball 14. The retaining ball 14 is easy for the operator to grip. By applying force to the retaining ball 14, the limiting post 12 can be moved, making the operation more labor-saving and convenient. The outer wall of the limiting post 12 is fitted with a spring 15. The spring 15 is an elastic element that plays a role in buffering and resetting when the limiting post 12 moves. Through elastic deformation and potential energy release, the condenser plate 10 can be automatically locked and unlocked.

[0034] Reference Figure 1 , Figure 3 and Figure 4The bottom of the sealing ring 8 is fixedly connected to one side of the chassis 2. This connection method allows the sealing ring 8 to be securely installed on the device, ensuring a tight fit during mechanical docking and achieving a good sealing effect. The rotating disk 5 has a hexagonal cross-sectional shape, which is compatible with common wrench tools, making it convenient for operators to quickly and accurately rotate the rotating disk 5, improving the efficiency of installation and adjustment. The top of the spring 15 is fixedly connected to the inner wall of the housing 1, and the bottom is fixedly connected to the top of the protrusion 13. This connection method allows the spring 15 to be able to move within the working area of ​​the protrusion 13. The ball undergoes elastic deformation, storing elastic potential energy, and releases this energy at an appropriate time. This energy drives the protrusion 13 to move the limiting post 12, thus engaging and disengaging the condenser plate 10. The outer wall of the protrusion 13 is slidably connected to the inner wall of the housing 1, ensuring that the protrusion 13 can slide along a predetermined trajectory during movement. This guarantees the stability and accuracy of the movement of the limiting post 12, thereby achieving reliable fixation of the condenser plate 10. The outer wall of the ball 14 contacts the top of the housing 1, facilitating gripping and force application by the operator. It also provides clear tactile feedback during operation, making it convenient for... The movement of the limiting post 12 is accurately controlled. The outer wall of the limiting post 12 is slidably connected to the inner wall of the groove 11. This sliding connection allows the limiting post 12 to precisely engage with the groove 11, enabling locking and unlocking of the condenser plate 10. This ensures the stability of the condenser plate 10 during operation and ease of replacement. The protrusion 13 has a circular cross-sectional shape. This design allows for better engagement with the spring 15 and provides greater stability when sliding within the housing 1, reducing wobbling. One side of the clamping block 6 contacts the inner wall of the housing 3. Driven by the stud 4, the clamping block 6 can... Moving along the inner wall of the outer casing 3, it clamps and fixes equipment of different specifications. The cross-sectional shape of the clamping block 6 is arc-shaped, which can better fit the surface of the equipment, increase the contact area, and improve the stability and reliability of clamping. The sealing ring 8 is annular in shape, which is compatible with the slot 9 and the overall structure of the device. It can form a complete sealing ring during mechanical docking, effectively preventing liquid leakage and impurity intrusion. The annular shape of the outer casing 3 provides a uniform and symmetrical installation space for components such as the stud 4 and the clamping block 6, and also facilitates the docking and installation of the device with other equipment.

[0035] Working principle: Rotating the rotating disk 5 causes the stud 4 to rotate, allowing the stud 4 to adjust its position on the inner wall of the outer casing 3. This allows for adjustment of the space formed by the three clamping blocks 6, enabling flexible adjustment of the interface specifications when facing different mechanical heat dissipation operations. This significantly improves the reusability across equipment. Thanks to the presence of the sealing ring 8, the machinery can achieve a seal when docking with the heat dissipation device. When the cooling effect of the condenser plate 10 decreases after the heat dissipation device has been operating for a certain period of time, pulling the retaining ball 14 causes the retaining ball 14 to move along with the limiting post. The protrusion 13 on the outer wall of 12 compresses the spring 15, causing the spring 15 to undergo elastic deformation, thereby unlocking the restriction of the condenser plate 10 and allowing the condenser plate 10 to be replaced. After the condenser plate 10 is replaced, the locking ball 14 is pulled again and the condenser plate 10 is slid back to its original position. The force acting on the locking ball 14 is released, causing the elastic potential energy stored in the spring 15 to be released instantly. This causes the spring 15 to push the protrusion 13 to drive the limiting post 12 to firmly lock the groove 11, thereby enabling the replacement of the condenser plate 10 and greatly improving the heat dissipation efficiency of the entire heat dissipation device.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
