Synchronizing propeller provided with sealing gaskets

Abstract

The invention discloses a synchronizing propeller provided with sealing gaskets. The synchronizing propeller is characterized by comprising an inner ring and an outer ring, wherein the inner ring is fixedly arranged, the outer ring surface of the inner ring is provided with an outer thread, the outer ring and the inner ring are coaxially arranged, the inner ring surface of the outer ring is provided with an inner thread meshed with the outer thread, the inner end face of the outer ring in the axial direction serves as a propelling end face, and the outer ring is subjected to axial feeding relative to the inner ring in the rotating process so as to enable the propelling end face to exert an axial propelling force. According to the synchronizing propeller provided with the sealing gaskets, it can be effectively guaranteed that propelling distances of sealing components in the propelling process are equal, and therefore contact between faying surfaces of the adjacent sealing components is stressed uniformly; therefore, it is guaranteed that an immersion tank has good sealing performance, and the immersion tank is prevented from leaking liquid.

Description

technical field [0001] The invention relates to a device for installing a mechanical sealing device, in particular to a device for installing a mechanical sealing device for an immersion tank. Background technique [0002] Many pollutants remain on the surface of the cold-rolled steel strip, for example, rolling oil, iron oxide powder or dust from the rolling process. If these pollutants are not completely removed during the galvanizing process, then these pollutants will form carbonaceous stains during the annealing process, thereby affecting the atmosphere in the polluted furnace, furnace rolls and strip quality. At present, during the galvanizing process, when cleaning a lot of rolling oil, iron oxide powder and pollutants in the rolling process on the surface, the strip needs to be cleaned in an immersion tank filled with lye. The sinking roller submerged in the solution of the immersion tank has a mechanical seal device, which is mainly composed of two parts, the movin...

Problems solved by technology

However, due to the use of artificially pushing the stopper in the prior art and relying on visual inspection to judge the uniformity of the feed of the moving ring and the static ring and the advancing distance of the stopper, the sealing effect between the static ring and the moving ring is not good. Not good, it often leads to leakage of immersion tank due to poor mechanical seal
