Description

Technical Field

[0001] This utility model relates to a silicon powder heater, specifically to a waterproof structure for the heating component of a silicon powder heater. Background Technology

[0002] Silicon powder heaters are core equipment in the cold hydrogen chemical process, and the stable operation of their heating components (mainly heating wires) is crucial to production efficiency and product quality. Currently, although there is considerable research on heating wire materials in China, with materials such as nickel-chromium alloys and iron-chromium-aluminum alloys being widely used, their corrosion resistance in humid environments remains insufficient.

[0003] While existing technologies have explored waterproof design for heaters, such as using shell materials with better sealing or adding waterproof layers, the waterproof effect is not ideal in high-temperature and high-humidity environments, leading to frequent water ingress problems in the heating wire.

[0004] Alternatively, breakthroughs could be made in the materials and waterproof design of the heating wire, such as developing new composite materials, adopting multi-layer insulation structures or nano-coating technology, but these methods are more expensive and their adaptability in certain working conditions needs to be improved.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example:

[0030] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a waterproof structure for the heating component of a silicon powder heater, including a junction box 10, a base plate 20, a cover plate 30, a receiving flange 40, and a rain shield 50. The junction box 10 is a cylindrical structure with through-type structures at both ends.

[0031] A cover plate 30 is provided at one end of the junction box 10, and a base plate 20 is provided at the other end.

[0032] Specifically, the base plate 20 has a through hole through which the heating element 60 can pass. The base plate 20 and the junction box 10 are tightly connected by welding, and the welding must be complete to ensure there are no gaps between the base plate 20 and the junction box 10, thereby preventing rainwater from seeping into the interior of the junction box 10. In addition, a sealant is applied between the heating element 60 and the base plate 20, which ensures the airtightness of the through hole.

[0033] The cover plate 30 is threaded to the end of the junction box 10. The cover plate 30 is also circular, and its outer diameter is larger than that of the junction box 10. Specifically, a ring-shaped protruding connecting portion is provided on one side of the cover plate 30, with external threads on its outer periphery and internal threads on the inner side of the end of the junction box 10. This allows the cover plate 30 to connect to the junction box 10 via the connecting portion.

[0034] The outer edge of the cover plate 30 protrudes from the outer surface of the junction box 10, and a water guide groove 31 is provided at the protruding position of the cover plate 30. The water guide groove 31 is annular and located on the side where the cover plate 30 is connected to the junction box 10, so that the water guide groove 31 can guide the rainwater on the side where the cover plate 30 is connected to the junction box 10.

[0035] The receiving flange 40 is located in the middle of the heating assembly 60 and can be connected to the blind pipe 70 (the part of the heater that is in operation) via the receiving flange 40.

[0036] The rain shield 50 is installed on the outer periphery of the gap at the connection between the receiving flange 40 and the blind pipe 70.

[0037] The rain shield 50 has an annular structure. After the receiving flange 40 and the blind pipe 70 are connected, their outer surfaces are on the same circumferential surface. The annular rain shield 50 covers the gap at the connection between the receiving flange 40 and the blind pipe 70, thus preventing rainwater from seeping into the gap between them. Generally, sealant is provided between the rain shield 50 and the receiving flange 40. This sealant covers the gap between the receiving flange 40 and the blind pipe 70. The pressure exerted by the rain shield 50 on the sealant further prevents moisture from entering the blind pipe 70.

[0038] Preferably, a sealing strip is provided at the connection end face between the junction box 10 and the cover plate 30. The junction box 10 and the cover plate 30, which are connected by threads, exert a squeezing effect on the sealing strip, which can further prevent moisture from entering the junction box 10.

[0039] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
