Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a carbon-based high-efficiency condenser. Background Technology

[0002] Carbon-based high-efficiency condensers refer to condensers made primarily of silicon carbide. Silicon carbide has a melting point as high as 2700℃ and can operate stably at temperatures above 1600℃ for extended periods. It is chemically inert to extreme media such as concentrated sulfuric acid, hydrofluoric acid, and molten salts, exhibiting strong corrosion resistance. Furthermore, its thermal conductivity is 120-270 W / (m・K), twice that of copper, demonstrating excellent corrosion resistance and high-temperature resistance.

[0003] For example, patent CN222460329U discloses a silicon carbide condenser that is easy to assemble and disassemble, including a main body mechanism and a connecting mechanism. The connecting mechanism is located at the left and right ends of the main body mechanism. The main body mechanism includes a support plate, a fixed plate, and a cylinder.

The transmission end of the cylinder extends to the middle of the fixed plate. The main body mechanism also includes a push rod, an arc-shaped clamping plate, a first retaining ring, and a second retaining ring. The push rod is fixedly installed in the middle of the transmission end of the cylinder, the arc-shaped clamping plate is fixedly installed in the middle of the push rod, and the first retaining ring is fixedly installed... At the left end of the middle of the arc-shaped clamp; the silicon carbide condenser is installed through the main body mechanism, which facilitates the disassembly and cleaning of the silicon carbide condenser, improves the firmness of the connection between the cover and the silicon carbide condenser, improves work efficiency, and improves practicality; however, silicon carbide material has the characteristics of high hardness and brittleness, which makes it prone to cracking when subjected to external impact, mechanical stress or rapid temperature change. Some existing condensers are not convenient to disassemble individual silicon carbide pipes. When the silicon carbide pipe cracks, it is inconvenient to disassemble it for repair or replacement, which is difficult and time-consuming.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing condenser. Utility Model Content

[0005] The purpose of this invention is to provide a carbon-based high-efficiency condenser to solve the problems mentioned in the background art, which state that silicon carbide material has high hardness and brittleness, making it prone to cracking when subjected to external impact, mechanical stress or rapid temperature changes. In addition, some existing condensers are not convenient to disassemble individual silicon carbide pipes, and when silicon carbide pipes crack, it is inconvenient to disassemble them for repair or replacement, resulting in difficult and time-consuming repairs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon-based high-efficiency condenser, comprising a condenser outer tube, with an inlet pipe and an outlet pipe installed through both ends of the condenser outer tube. Two sets of fixing rings are fixed at the two ends of the condenser outer tube near the inlet pipe and the outlet pipe, respectively. Multiple silicon carbide tubes are installed through the two sets of fixing rings. The fixing rings are provided with a positioning mechanism to reinforce the installation position of the silicon carbide tubes. A pressure ring is fitted and fixed inside the inlet pipe. The pressure ring has a circular groove for engaging and connecting with the silicon carbide tubes. The pressure ring is also provided with a pressing mechanism to further reinforce the installation stability of the silicon carbide tubes.

[0007] Preferably, the positioning mechanism includes a positioning ring fixedly sleeved on the outside of the silicon carbide tube, the positioning ring being attached to the surface of the fixed ring, and the positioning ring having positioning grooves symmetrically formed about the central axis; the surface of the fixed ring is fixed with elastic locking posts that penetrate and engage with the positioning grooves.

[0008] Preferably, the elastic locking post has two sets of locking blocks that engage with the surface of the positioning ring, and a through groove is provided in the middle of the elastic locking post; the two sets of locking blocks are symmetrically arranged on both sides of the through groove.

[0009] Preferably, the pressing mechanism includes a pressing column fixedly installed on the pressing ring, and the pressing column is engaged with a through groove on the elastic locking column.

[0010] Preferably, the pressing mechanism further includes a limiting rod fixed on the pressing ring, and the positioning ring has a limiting groove that engages with the limiting rod.

[0011] Preferably, a sealing ring is fitted and fixed in the circular groove on the pressure ring, the inner wall of the sealing ring is inclined, and the inner inclined surface of the sealing ring is pressed against the outside of the silicon carbide tube.

[0012] Preferably, two sets of flow-blocking plates are fixedly installed on the inner wall of the condenser outer tube; the flow-blocking plates are provided with multiple through slots that engage with the silicon carbide tube, and multiple elastic buffer sheets are fixed at equal angles outside the through slots on the flow-blocking plates, the elastic buffer sheets being elastically pressed against the outside of the silicon carbide tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the carbon-based high-efficiency condenser makes it easy to disassemble individual silicon carbide tubes, facilitating their repair or replacement, reducing the overall maintenance difficulty of the condenser and shortening the time required. Silicon carbide has extremely high bond energy and a stable structure. Through the use of silicon carbide tubes, the condenser possesses excellent high-temperature resistance and corrosion resistance. At the same time, silicon carbide material has a high thermal conductivity, enabling rapid heat exchange and helping the medium to cool down quickly when flowing inside the equipment, thereby improving cooling efficiency.

[0014] The fixing ring is equipped with a positioning mechanism to reinforce the installation position of the silicon carbide tube. The silicon carbide tube passes through the fixing ring and is fixed in position at the port of the fixing ring by the positioning ring. Under the elastic engagement of the positioning ring with the spring-loaded pin, the position of the silicon carbide tube on the condenser can be initially fixed to maintain the installation stability.

[0015] Furthermore, the pressure ring is equipped with a pressing mechanism to further enhance the installation stability of the silicon carbide tube. When the water inlet pipe is installed next to the condenser outer pipe with bolts, the pressure post on the pressure ring is pressed into the middle position of the elastic locking post, keeping the elastic locking post in a state of elastic locking outside the positioning ring. At the same time, the limiting rod on the pressure ring is pressed into the limiting groove on the positioning ring, further limiting the installation stability of the silicon carbide tube.

[0016] When the silicon carbide tube is installed inside the condenser outer tube, it passes through the baffle plate. The elastic buffer sheet on the baffle plate is pressed against the outer wall of the silicon carbide tube, which can keep the silicon carbide tube stably installed in the condenser outer tube and reduce the impact of the medium on the silicon carbide tube during operation.

[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. 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.

[0028] Example 1: Please refer to Figures 1-5 The present invention provides the following technical solution: a carbon-based high-efficiency condenser, comprising a condenser outer tube 1, with an inlet pipe 2 and an outlet pipe 3 installed through both ends of the condenser outer tube 1. Two sets of fixing rings 4 are fixed at the two ends of the condenser outer tube 1 near the inlet pipe 2 and the outlet pipe 3, respectively. Multiple silicon carbide tubes 5 are installed through the two sets of fixing rings 4. The fixing rings 4 are provided with a positioning mechanism to reinforce the installation position of the silicon carbide tubes 5. A pressure ring 11 is fitted and fixed inside the inlet pipe 2. The pressure ring 11 has a circular groove 12 that engages with the silicon carbide tubes 5, and the pressure ring 11 is provided with a pressing mechanism to further reinforce the installation stability of the silicon carbide tubes 5.

[0029] Please see Figures 2-7 The positioning mechanism includes a positioning ring 6 fixedly sleeved on the outside of the silicon carbide tube 5. The positioning ring 6 is attached to the surface of the fixed ring 4, and positioning grooves 7 are symmetrically formed on the positioning ring 6 about the central axis. A spring-loaded locking post 8 is fixed to the surface of the fixed ring 4 and engages with the positioning groove 7. Two sets of locking blocks 9 are fixed to the spring-loaded locking post 8 and engage with the surface of the positioning ring 6. A through groove 10 is formed in the middle of the spring-loaded locking post 8. The two sets of locking blocks 9 are symmetrically arranged on both sides of the through groove 10.

[0030] Please see Figures 5-8 The pressing mechanism includes a pressing post 13 fixedly mounted on the pressing ring 11, which engages with a through groove 10 on the elastic locking post 8. The pressing mechanism also includes a limiting rod 14 fixed on the pressing ring 11, and a limiting groove 15 is provided on the positioning ring 6 to engage with the limiting rod 14.

[0031] When assembling the condenser, the silicon carbide tube 5 is installed sequentially in the outer condenser tube 1. The silicon carbide tube 5 passes through the fixing ring 4. When assembled, the positioning ring 6 outside the silicon carbide tube 5 is pressed against the surface of the fixing ring 4. The elastic locking post 8 on the fixing ring 4 passes through the positioning groove 7 opened on the positioning ring 6. The locking block 9 on the elastic locking post 8 first contacts and deforms with the inner wall of the positioning groove 7. Finally, the locking block 9 elastically engages with the surface of the positioning ring 6, thus initially defining the installation position of the silicon carbide tube 5.

[0032] When the water inlet pipe 2 is installed at one end of the condenser outer pipe 1, the pressure ring 11 in the water inlet pipe 2 is fitted onto the outside of the silicon carbide tube 5 through the circular groove 12. The pressure post 13 on the pressure ring 11 enters the through groove 10 opened on the elastic locking post 8, and the pressure post 13 pushes the two sets of locking blocks 9 to expand outward, keeping the locking blocks 9 locked and pressed against the surface of the positioning ring 6. At the same time, the limiting rod 14 on the pressure ring 11 engages into the limiting groove 15 on the surface of the positioning ring 6, further limiting the installation position of the positioning ring 6 and the silicon carbide tube 5, and keeping the installation of the silicon carbide tube 5 stable.

[0033] Silicon carbide tube 5 has strong corrosion resistance and high temperature resistance, but it is also characterized by high hardness and brittleness. It is prone to cracking when subjected to external impact, mechanical stress, or rapid temperature changes. If a single silicon carbide tube 5 cracks, the inlet pipe 2 can be removed from the condenser outer pipe 1 first. Then, press the two sets of clips 9 on the elastic clip 8 to remove the positioning ring 6 and silicon carbide tube 5 from the fixing ring 4. This makes it easy to disassemble and replace a single silicon carbide tube 5, facilitating maintenance operations.

[0034] Example 2: Please refer to Figure 6 and Figure 9 Based on Embodiment 1, a sealing ring 16 and a flow-blocking plate 17 are also disclosed, with the following specific structure: A sealing ring 16 is fitted and fixed in the circular groove 12 on the pressure ring 11. The inner wall of the sealing ring 16 is inclined, and the inclined inner surface of the sealing ring 16 is pressed against the outside of the silicon carbide tube 5. Two sets of flow-blocking plates 17 are fixedly installed on the inner wall of the condenser outer tube 1. The flow-blocking plate 17 has multiple through grooves 171 that engage with the silicon carbide tube 5, and multiple elastic buffer pieces 172 are fixed at equal angles on the flow-blocking plate 17 outside the through grooves 171. The elastic buffer pieces 172 are elastically pressed against the outside of the silicon carbide tube 5.

[0035] When the silicon carbide tube 5 is installed inside the condenser outer tube 1, the silicon carbide tube 5 passes through the through groove 171 on the baffle plate 17, and the elastic buffer sheet 172 on the baffle plate 17 is elastically pressed against the outer wall of the silicon carbide tube 5, keeping the silicon carbide tube 5 relatively stable in the baffle plate 17. When the medium flowing inside the silicon carbide tube 5 is cooled by the medium in the condenser outer tube 1, the elastic protection of the elastic buffer sheet 172 can maintain the stability of the installation structure of the silicon carbide tube 5 and reduce the impact interference of the medium.

[0036] When the silicon carbide tube 5 and the pressure ring 11 are assembled, the sealing ring 16 in the pressure ring 11 is pressed against the outer wall of the silicon carbide tube 5, which can improve the sealing performance of the assembly of the silicon carbide tube 5 and the pressure ring 11, and ensure that the circulating medium completely passes through the interior of the silicon carbide tube 5.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Although the present invention 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.
