Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of silicon carbide heat exchangers, specifically a high-temperature resistant and corrosion-resistant silicon carbide heat exchanger. Background Technology
[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.
[0003] Silicon carbide heat exchangers have good high temperature resistance and corrosion resistance, but the height of silicon carbide heat exchangers is usually fixed. When silicon carbide heat exchangers need to be repaired, it is difficult to reach the key parts, or it is necessary to remove the surrounding equipment to carry out the work, which prolongs the maintenance time and increases downtime losses. Summary of the Invention
[0004] The purpose of this invention is to provide a high-temperature resistant and corrosion-resistant silicon carbide heat exchanger, which allows for flexible height adjustment, facilitates maintenance, and improves work efficiency.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-temperature resistant and corrosion-resistant silicon carbide heat exchanger is provided, including a mounting base. A first movable groove is formed on the upper surface of the mounting base. A double-threaded screw is movably installed on the inner wall of the first movable groove. A first movable block is threadedly connected to the outer surface of the double-threaded screw. There are two first movable blocks. A connecting plate is fixedly connected to the upper surface of each first movable block. There are two connecting plates. A fixed shaft is fixedly connected between adjacent connecting plates. A deflection arm is sleeved on the outer surface of the fixed shaft. A connecting block is movably installed at the end of the deflection arm away from the fixed shaft. A second movable block is fixedly connected to the side wall of the connecting block. A pressing member is fixedly connected to the upper surface of the second movable block.
[0006] Optionally, a fixing seat is fixedly connected to the upper surface of the mounting base, and there are two fixing seats. A second moving groove is opened inside the fixing seat, and the second moving block is located inside the second moving groove.
[0007] Optionally, a limiting groove is formed on the inner wall of the second moving groove, and the connecting block is located inside the limiting groove.
[0008] Optionally, a throttle is fixedly connected to the side wall of the double-threaded screw, and a rotating rod is fixedly connected to the side wall of the throttle.
[0009] Optionally, the upper surface of the pressing member is provided with a second threaded hole, and there are multiple second threaded holes, with bolts threadedly connected to the inner surface of the second threaded hole.
[0010] Optionally, an upper pressure member is provided above the lower pressure member, and a first threaded hole is provided on the upper surface of the upper pressure member. There are multiple first threaded holes, and bolts are threadedly connected to the inner surface of the first threaded holes.
[0011] Optionally, a nut is threaded onto the outer surface of the bolt, and the nut is in contact with the lower surface of the pressing member.
[0012] Optionally, the lower surface of the mounting base is fixedly connected with four legs.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model includes a rotating rod, a rotating handle, a double-threaded screw, a first moving block, a deflection arm, a connecting block, a second moving block, and a pressing component. When the height of the heat exchanger needs to be adjusted, the rotating rod can be gripped to rotate the rotating handle, which in turn rotates the double-threaded screw. This causes the adjacent first moving blocks to move closer or further apart, which in turn causes the adjacent deflection arm to shift, thereby causing the adjacent connecting block to rise or fall. This, in turn, causes the adjacent second moving block to rise or fall, and thus causes the adjacent pressing component to rise or fall. This allows the height of the heat exchange tube to be changed. This utility model can flexibly adjust the height of the heat exchanger, making maintenance easier and improving work efficiency.
[0015] This utility model is provided with a limiting groove, a connecting block, a second moving block and a pressing member. The limiting groove can limit the moving height of the connecting block, thereby limiting the moving height of the second moving block and the pressing member, and thus limiting the height of the heat exchanger.

[0028] Reference Figure 1-6The present invention will now describe a high-temperature resistant and corrosion-resistant silicon carbide heat exchanger provided in the embodiments of the present invention. A high-temperature resistant and corrosion-resistant silicon carbide heat exchanger includes a mounting base 1. A first movable groove 2 is formed on the upper surface of the mounting base 1. A double-threaded screw 3 is movably mounted on the inner wall of the first movable groove 2. Two first movable blocks 4 are threadedly connected to the outer surface of the double-threaded screw 3. A connecting plate 5 is fixedly connected to the upper surface of each first movable block 4. A fixed shaft 6 is fixedly connected between adjacent connecting plates 5. A deflecting arm 7 is sleeved on the outer surface of the fixed shaft 6. A connecting block 8 is movably mounted at the end of the deflecting arm 7 away from the fixed shaft 6. A second movable block 9 is fixedly connected to the side wall of the connecting block 8. A pressing member 10 is fixedly connected to the upper surface of the second movable block 9. When the height of the heat exchanger needs to be adjusted, the handle 14 is rotated by holding the rotating rod 15, which rotates the double-threaded screw 3, causing the adjacent first movable blocks 4 to move closer or further apart. This causes the adjacent deflecting arms 7 to shift, thereby causing the adjacent connecting blocks 8 to rise or fall. The lowering of the second moving block 9 causes the adjacent second moving block 9 to rise or fall, which in turn causes the adjacent lowering member 10 to rise or fall, thereby changing the height of the heat exchanger. The upper surface of the mounting base 1 is fixedly connected to a fixed base 11, and there are two fixed bases 11. The interior of the fixed base 11 is provided with a second moving groove 12, and the second moving block 9 is located inside the second moving groove 12. The second moving groove 12 can restrict the movement of the second moving block 9 to prevent the second moving block 9 from deviating when moving up and down. The inner wall of the second moving groove 12 is provided with a limiting groove 13, and the connecting block 8 is located inside the limiting groove 13. The limiting groove 13 can limit the movement height of the connecting block 8, thereby limiting the movement height of the second moving block 9 and the lowering member 10, and thus limiting the height of the heat exchanger. The side wall of the double threaded screw 3 is fixedly connected to a handle 14, and the side wall of the handle 14 is fixedly connected to a rotating rod 15. By holding the rotating rod 15, the handle 14 can be rotated, which drives the double threaded screw 3 to rotate.
[0029] This utility model provides a high-temperature resistant and corrosion-resistant silicon carbide heat exchanger. Compared with the prior art, the height of the heat exchanger can be flexibly adjusted, which facilitates maintenance and improves work efficiency.
[0030] Please refer to another embodiment of this utility model as well.

The inner surface of the second threaded hole 18 is threaded with a bolt 19. An upper pressure member 16 is provided above the lower pressure member 10. The upper surface of the upper pressure member 16 is provided with a first threaded hole 17, and there are multiple first threaded holes 17. The inner surface of the first threaded hole 17 is threaded with a bolt 19. The outer surface of the bolt 19 is threaded with a nut 20. The nut 20 fits against the lower surface of the lower pressure member 10. The upper pressure member 16 and the lower pressure member 10 are fixed together by the bolt 19 and the nut 20, which can clamp the heat exchanger.
[0031] In another embodiment of this utility model, please refer to Figures 1 to 6 The lower surface of the mounting base 1 is fixedly connected with four support legs 21, which can support the mounting base 1.
