It includes an inlet pipe, an inlet valve, a fan, an electric heater, an air distributor, a heat exchange tube bundle, an air manifold, an outlet valve, and the heat exchange tube bundle is located inside the heat exchanger. The inlet pipe is connected to the inlet of the air distributor via the inlet valve, fan, and electric heater. The outlet of the air distributor is connected to the inlet of the heat exchange tube bundle, and the outlet of the heat exchange tube bundle is connected to the inlet of the air manifold. When using this patent, the inlet and outlet valves are opened, the recirculation valve is closed, and the electric heater is de-energized and off. Room temperature air output by the fan enters the heat exchange tube bundle after passing through the air distributor. The heat exchanger serves as a cold source to cool the sodium vapor carried by the argon gas in the argon gas flow channel. After the air inside the heat exchanger tube bundle is heated, it enters the air manifold and is then discharged to the atmosphere through the outlet valve. However, the above-mentioned existing patents still have some shortcomings in actual use. Because the heat exchanger in the above-mentioned existing patents is equipped with components such as fine mechanical filters and heat exchanger baffles, but the heat exchanger is connected to the air distributor and air manifold by welding or bolting, when the heat exchanger or its internal components are damaged, the entire heat exchanger assembly must be removed, which requires a long downtime, and frequent disassembly and assembly can easily cause wear on the connection parts.

[0004] Therefore, there is a need to provide a modular, detachable pressure relief valve collection device. Utility Model Content

[0005] To overcome the shortcomings of existing patents where heat exchangers contain fine mechanical filters and heat exchanger baffles, but are connected to air distributors and air manifolds by welding or bolting, requiring the entire heat exchanger assembly to be removed when the heat exchanger or its internal components are damaged, resulting in long downtime and wear on the connection points due to frequent disassembly and assembly, this utility model provides a modular, detachable pressure relief valve collection device. This device uses components such as sleeves, screws, and ball catches to quickly disassemble and assemble components, facilitating maintenance.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a modular, detachable pressure relief valve collection device, comprising a collection tank, a connecting pipe, a valve, a sealing ring, a compression ring, an air inlet pipe, a sealing cap, a connecting flange, a mounting flange, an air bladder, and an air inlet interface.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0024] Example 1: A modular and detachable pressure relief valve collection device, see reference. Figures 1-6As shown, the system includes a collection tank 1, a connecting pipe 101, a valve 102, a sealing ring 6, a compression ring 7, an air inlet pipe 103, a sealing cap 8, a connecting flange 2, a mounting flange 3, an air bladder 4, and an air inlet port 5. The bottom of the collection tank 1 is connected to the connecting pipe 101, and the air inlet pipe 103 is connected to the connecting pipe 101. The valve 102 is installed on the connecting pipe 101. The top of the collection tank 1 is fixedly connected to the connecting flange 2, and the mounting flange 3 is installed on the connecting flange 2. The sealing ring 6 is installed on the mounting flange 3, and the air bladder 4 is secured between the sealing ring 6 and the mounting flange 3. The air bladder 4 is located within the collection tank. Inside the tank 1, a compression ring 7 is provided on the mounting flange 3, and a sealing cover 8 is provided on the compression ring 7. An air inlet 5 is connected to the sealing cover 8, and the air inlet 5 is connected to the airbag 4. It also includes a sleeve 9, a retaining ball 10, a screw 11, and a boss 12. Four sleeves 9 are provided on the sealing cover 8 by welding. The four sleeves 9 pass through the compression ring 7, the sealing ring 6, the mounting flange 3, and the connecting flange 2. A screw 11 is threaded on the sleeve 9. A boss 12 is fixedly connected to the lower part of the screw 11. A retaining ball 10 is symmetrically held in the lower part of the sleeve 9. The retaining ball 10 is located inside the boss 12.

[0025] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a lever is fixedly connected to the screw 11 to facilitate the rotation of the screw 11.

[0026] See Figure 1 As shown, it also includes a pressure gauge 24, which is installed on the collection tank 1.

[0027] When using the pressure relief valve collection device, first place the mounting flange 3 above the connecting flange 2 and secure the airbag 4 to the mounting flange 3. Then, place the sealing ring 6 on the mounting flange 3, and then place the compression ring 7 on the sealing ring 6, aligning the mounting holes on the compression ring 7, sealing ring 6, mounting flange 3, and connecting flange 2. Next, cover the compression ring 7 with the sealing cap 8, and insert the four sleeves 9 on the sealing cap 8 into the mounting holes on the sealing ring 6, mounting flange 3, and connecting flange 2. Then, rotate the screw 11, causing the screw 11 to move the boss 12 downwards, while the boss 12 compresses the two retaining balls 10 towards... The ball 10 moves outward, pressing against the connecting flange 2 for quick installation, thus facilitating disassembly and assembly. This allows for easy removal of the collecting components and convenient maintenance. After installation, water is injected into the air bladder 4, causing it to expand and block the connecting pipe 101. The inlet pipe 103 is then connected to the outlet pipe of the corresponding equipment. When collecting sodium vapor, the valve 102 is opened, allowing sodium vapor to enter the collecting tank 1 through the connecting pipe 101. As the amount of sodium vapor increases, it compresses the air bladder 4, allowing the sodium vapor to enter the collecting tank 1. Simultaneously, the air bladder 4 contracts, expelling the water inside. The pressure gauge displays the pressure inside the collecting tank 1 in real time.

[0028] Example 2: Based on Example 1, refer to Figure 2 and Figure 6 As shown, it also includes a rubber ring 13, a fixing frame 14, a guide rod 15, a sealing plug 16, and an elastic element 17. The fixing frame 14 is fixedly connected inside the air inlet tank, and the rubber ring 13 is fixedly connected inside the air inlet tank. The rubber ring 13 is located in front of the fixing frame 14. The guide rod 15 is slidably arranged on the fixing frame 14. The end of the guide rod 15 is fixedly connected to the sealing plug 16, which is stuck on the rubber ring 13. The elastic element 17 is sleeved on the guide rod 15, and the two ends of the elastic element 17 are distributed and connected to the fixing frame 14 and the sealing plug 16.

[0029] When collecting sodium vapor, the gas pushes the sealing plug 16 to move backward, which in turn moves the guide rod 15 backward. The elastic element 17 is compressed accordingly. When no gas continues to enter after collection is completed, the elastic element 17 rebounds and moves the guide rod 15 and the sealing plug 16 forward, so that the sealing plug 16 blocks the buckle on the rubber ring 13, thereby preventing sodium vapor from flowing back and thus preventing gas leakage.

[0030] See Figure 1 and Figure 7 As shown, it also includes a placement seat 18, a protrusion 19, a support rod 20, a fixing seat 21, and a limiting bolt 22. The fixing seat 21 is provided on the support rod 20 by means of bolt connection. The protrusion 19 is locked in each of the three fixing seats 21. The limiting bolt 22 is threaded on the fixing seat 21 and is threadedly connected to the protrusion 19. The placement seat 18 is provided between the three protrusions 19 by means of welding. The collection tank 1 is locked on the placement seat 18.

[0031] See Figure 7 As shown, it also includes a base plate 23, and the base plate 23 is fixedly connected between the bottom ends of the three support rods 20.

[0032] When it is necessary to install the pressure relief valve collection device, place the base plate 23 in the designated position, and then place the placement seat 18 between the three fixed seats 21 so that the protrusion 19 is inserted into the fixed seat 21. Then screw the limiting bolt 22 into the fixed seat 21 and the protrusion 19 to quickly fix the protrusion 19 on the fixed seat 21, thereby achieving the function of quick disassembly and assembly, facilitating transportation. After the installation is completed, place the collection tank 1 on the placement seat 18, and then carry out the subsequent installation.
