[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1~Figure 5As shown, this embodiment proposes a tubular graphite heat exchanger for producing phosphate triesters, including a base 1 and a tubular radiator 5, the top of the base 1 is fixedly connected to a connecting plate 2 by screws, the two sides of the connecting plate 2 are respectively fixedly connected to a fixing bracket 3 by screws, the top of the fixing bracket 3 is fixedly connected to a connecting plate 4 by screws, the top of the connecting plate 4 is fixedly connected to a fixing ring 7 by screws, a first turntable 13 is rotatably installed inside the fixing ring 7, the top of the first turntable 13 is fixedly connected to three circumferentially evenly distributed connecting columns by screws, the tops of the three connecting columns are commonly fixedly connected to a second turntable 15 by screws, three circumferentially evenly distributed sliders 16 are commonly movably hinged between the first turntable 13 and the second turntable 15, and the fixing One side of the fixed ring 7 is movably hinged with three rotating rods 14 evenly distributed in a circle. The rotating rod 14 is slidably assembled inside the slider 16. A clamping block 17 is rotatably installed inside the rotating rod 14. The arrangement of the clamping block 17 and other structures simplifies the installation process of the tubular radiator 5. The linkage mechanism of the knob 10, the threaded rod 11 and the movable block 12 is utilized to achieve rapid and stable clamping of the radiator body, and the clamping block 17 made of rubber material avoids surface damage. When producing triester phosphate, the water flow in the graphite tube 18 effectively absorbs and dissipates the reaction heat, and the internal temperature is monitored in real time through the display panel 6 to ensure the heat dissipation effect. When disassembling and repairing, the fixation can be easily released by rotating the knob 10 in the opposite direction, which reflects the convenience of operation.

[0029] like Figure 1~Figure 5 As shown, a rotating block 8 is rotatably installed inside the fixing ring 7, and a fixed block 9 is fixedly connected to the top of the rotating block 8 by screws. A threaded rod 11 is rotatably installed inside the fixed block 9, and a knob 10 is fixedly sleeved on the outer circumference of the threaded rod 11. A moving block 12 is movably hinged on the top of the first turntable 13, and the threaded rod 11 is threadedly connected to the inside of the moving block 12. A sliding groove is provided inside the forehead of the slider 16, and a rotating rod 14 is slidably connected to the inside of the sliding groove. A rotating groove is provided inside the rotating rod 14, and a clamping block 17 is rotatably installed inside the rotating groove. The clamping block 17 is made of rubber, and a threaded groove is provided inside the moving block 12. The threaded rod 11 is threadedly connected to the inside of the threaded groove. Two symmetrically arranged graphite tubes 18 are fixedly connected to the inside of the tubular radiator 5, and output tubes 19 are respectively provided on both sides of the graphite tube 18. A display panel 6 is installed on the outer circumference of the tubular radiator 5.

[0030] In this embodiment, when using this device, first move the base 1 to the place where it needs to be installed for pre-installation, then put the tubular radiator 5 into the first turntable 13, and then turn the knob 10. When the knob 10 is turned, it will drive the threaded rod 11 to rotate together, and the threaded rod 11 will drive the moving block 12 to move outward along the direction of the threaded rod 11, thereby driving the first turntable 13 and the second turntable 15 to rotate at the same time. At this time, the rotating rod 14 slides outward along the direction of the slider 16, thereby driving the three clamping blocks 17 to clamp and fix the main body of the tubular radiator 5 at the same time. Because the clamping block 17 is made of rubber, it will not cause damage to the surface of the tubular radiator 5. After the tubular radiator 5 is clamped and fixed, in the process of producing trisphosphate, the water flow that absorbs the reaction heat will enter through the output pipe 19 and then enter the interior of the graphite tube 18 to dissipate the heat, and finally output from the output pipe 19 at the other end to achieve a heat dissipation effect. The internal temperature can be observed through the display panel 6, and no more details will be given here.

[0031] Furthermore, when disassembly and maintenance are required, the knob 10 only needs to be rotated in the reverse direction to release the fibers and complete the disassembly, thus achieving a convenient fixing effect.

[0032] Example 2

[0033] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that four sleeve rods 21 evenly distributed in a rectangular array are welded to the bottom of the base 1, and the inner sliding assembly of the sleeve rod 21 is equipped with a support foot 22, and the top of the support foot 22 is fixedly connected to a boss 24 by screws.

[0034] like Figure 1~Figure 5 As shown, a slide groove is provided inside the base 1, a second shock-absorbing spring 20 is fixedly connected between the top wall of the slide groove and the support foot 22, and a first shock-absorbing spring 23 is fixedly connected between the top wall of the slide groove and the convex seat 24.

[0035] In this embodiment, when vibration is transmitted to the support foot 22, the shock absorbing spring 1 23 and the shock absorbing spring 20 will be deformed to absorb the vibration, thereby reducing the vibration transmitted to the tubular radiator 5, preventing damage to the graphite tube 18, and enhancing the shock absorbing effect.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
