Description

Technical Field

[0001] The utility model relates to the technical field of solar material processing, in particular to a fluororubber O-ring for a solar multi-crystal reduction furnace. Background Art

[0002] As the demand for renewable energy continues to increase, the solar industry has gradually become an important part of the global energy industry. Solar panels are the core components of solar power generation systems, and polysilicon is one of the main raw materials for solar panels. In the production process of polysilicon, the solar polycrystalline reduction furnace plays a vital role. It reduces silicon ore into high-purity polysilicon raw materials through chemical reactions, providing key materials for the production of solar panels.

[0003] In the prior art, fluororubber O-rings are usually made of fluororubber, which has excellent high temperature resistance and chemical stability, and can maintain good sealing performance for a long time at high temperature, thereby ensuring the smooth progress of the production process. Announcement No.: CN220118621U discloses a fluororubber O-type seal, in which a connector is provided on the fluororubber O-type seal ring, and the contact surface between the two fluororubber O-rings can be increased through the connector. When the ring body is pressurized, the inner wall of the convex cavity of the fluororubber O-ring will completely cling to and squeeze the outer wall of the connector, thereby increasing the sealing performance of the fluororubber O-ring and increasing the stability of the contact between the two fluororubber O-rings.

[0004] However, when the device is in use, the support strength of a single fluororubber O-ring is not high, which may lead to a decrease in sealing performance and cause the medium to leak or enter the sealing area, thereby affecting the normal operation of the equipment, resulting in frequent replacement of fluororubber O-rings, and increasing maintenance costs and downtime.

[0005] Based on this, fluororubber O-rings for solar multi-crystalline reduction furnaces are now provided to eliminate the drawbacks of existing devices. Utility Model Content
