Sink roll with throughflow holes

Abstract

The invention discloses a sink roll with throughflow holes. The sink roll with the throughflow holes comprises a roll barrel, a roll shaft and two connection shaft sleeves; the connection shaft sleeves are of a stepped structure, and the big end of each connection shaft sleeve is a flange plate; rabbet holes on the two ends of the roll barrel are sleeved with and fixedly connected on the flanges plate of the connection shaft sleeves; the roll shaft is of an integral structure penetrating through inner holes of the two connection shaft sleeves in the axial direction, and fixedly connected withthe two connection shaft sleeves; a plurality of axial through holes which are circumferentially arranged and communicated with an inside cavity of the roll barrel are formed in the flange plates of the connection shaft sleeves; the sink roll is further characterized in that grooves are correspondingly formed in the external end parts of the external circumferential juncture of the flange plates of the connection shaft sleeves and the rabbet holes of the roll barrel, and welding lines are arranged inside the grooves. The sink roll with the throughflow holes has high structure strength and highrigidity, and the zinc liquid can flow through the inside cavity of the shaft barrel when the sink roll with the throughflow holes is used.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a sinking roller on a hot-dip galvanizing device. Background technique [0002] The sinking roller on the existing hot-dip galvanizing device generally includes a roller, two roller shafts, and two connecting bushings. The connecting bushings have a stepped structure, and the big end is a flange. The connecting shaft sleeve flange is fixedly connected; the small end of the connecting shaft sleeve is set on one end of the roller shaft and fixedly connected. The main defects of this kind of sinking roller are: first, the structural strength and rigidity are poor; flow through the inner cavity of the roller. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a sinking roller provided with flow holes, which can significantly improve the structural strength and rigidity, and realize the circulation of zinc liquid fro...
