Centrifugal machine for bolt galvanizing line

Abstract

The invention discloses a centrifugal machine for a bolt galvanizing line. A driving motor and a centrifuging component are arranged in a frame side by side; a small motor pulley of the driving motoris connected with a large pulley on a driving shaft part; the upper surface of a power cone at the bottom center of a centrifuging barrel is provided with a plurality of rib plates from the center tothe periphery; the middle of a bottom plate of a bolt barrel is recessed into the bolt barrel; the lower surface of the bottom plate is provided with a plurality reinforcing bars from the center to the periphery; the bottom plate is seated on the power cone; each rib plate is arranged between the adjacent reinforcing bars. The bolt barrel and the centrifuging barrel are directly centered via a conical face; the bolt barrel and the centrifuging barrel are tightly connected with a very small gap left; the conical face can disperse and eliminate eccentric force; the power cone enables the whole bottom plate of the centrifuging barrel to be tightly connected with the driving shaft, thereby improving transmission connection strength and supporting force; the mutually matched ribs and rib platesarranged in radially surrounding form are used to transmit power, so that speed can be stably increased and high yield is guaranteed.

Description

technical field [0001] The invention relates to a centrifuge, in particular to a centrifuge for a bolt galvanizing production line, which belongs to centrifugal processing machinery. Background technique [0002] In the production and processing of bolts, in order to enhance the corrosion resistance of bolts, the manufactured bolts need to be placed in a zinc pot for galvanizing treatment. After galvanized bolts leave the zinc pot, a lot of zinc liquid will inevitably remain on the surface. After the liquid is cooled, lines and nodules are formed on the surface of the bolts, and the excessively thick zinc layer affects the accuracy and dimensions of the bolts and threads; therefore, the hot-dip galvanized bolts leave the zinc pot and enter the centrifuge as soon as possible, and the bolts are rotated at high speed by the centrifuge. The excess zinc liquid on the surface is thrown off, so the performance of the centrifuge affects the final galvanizing quality of the hot-dip g...

AI Technical Summary

Problems solved by technology

However, in the current centrifugation operation of bolts after galvanizing, multiple bolts are directly added to the centrifuge container. Since the connection strength between the centrifuge container and the drive shaft is not high, it is very easy to cause the centrifuge to deviate from the axis during rotation. , causing great damage to the entire centrifuge device, making the operation of the centrifuge very unstable; in addition, the bolts are scattered, and the distribution in the centrifuge container is uneven during rotation, and it is easy to generate additional eccentric force on the centrifuge container, and the eccentric operation It further affects the increase of the centrifugal speed of the centrifuge, and the general operating speed can only be kept at 400-800rmp, which seriously affects the final galvanizing quality of hot-dip galvanized bolts
