AI Technical Summary

Technical Problem

In alcohol-based laboratories, the connection between the stirring motor shaft and the cover plate of the synthesis reactor is prone to air and liquid leakage, which causes dust and impurities to be drawn into the connection between the motor shaft and the cover plate, affecting the normal operation and safe production of the synthesis reactor.

Method used

A synthetic reactor skeleton oil seal fixing ring was designed, comprising a fixing ring body, a skeleton sealing ring, an annular protrusion, a negative pressure sealing compensation component, and a silicone rubber membrane. The silicone rubber membrane and elastic rubber block deform and fill the gaps under negative pressure to seal, preventing impurities from entering.

Benefits of technology

It effectively seals the gap between the motor shaft and the reactor body, preventing air and impurities from entering the synthesis reactor, improving the sealing effect, reducing wear, and ensuring the normal operation and safe production of the synthesis reactor.

Abstract

This invention discloses a synthetic reactor skeleton oil seal fixing ring, relating to the field of skeleton oil seal technology. It includes a fixing ring body, a skeleton sealing ring on one side of the fixing ring body, and an annular protrusion on one side of the skeleton sealing ring. An annular groove mates with the annular protrusion. Negative pressure sealing compensation components are provided on both the inner and outer sides of the fixing ring body. This invention utilizes a silicone rubber membrane. When the interior is under negative pressure, a pressure difference is generated. This pressure difference applies a force towards the interior of the reactor to the silicone rubber membrane installed on the sidewall of the annular groove. Due to the elasticity of the silicone rubber membrane, it deforms, extending towards the lower pressure area (the interior of the reactor), thereby filling the gap between the motor shaft and the fixing ring body, achieving a seal and preventing the intake of air and impurities through the gap.
