Description

Zinc smoke recycling cover of zinc pot with lateral sliding door end entering side and exiting side Technical Field The application relates to the technical field of hot galvanizing equipment, in particular to a zinc fume recovery cover of a zinc pot with a transverse sliding door end inlet side outlet. Background The hot galvanizing process is usually implemented in a closed zinc pot zinc fume recovery hood. The zinc pot zinc fume recovery cover is generally made of high-temperature resistant materials, so that the zinc pot zinc fume recovery cover has good heat insulation performance and corrosion resistance. The zinc pot zinc smoke recovery cover top is provided with vertical and horizontal double track, and its terminal surface is provided with horizontal push-and-pull door, RGV charge car accessible setting realizes the function of material loading and getting on the track. Meanwhile, an electric hoist and a lifting hook are arranged at the bottom of the RGV feeding car and are used for lifting metal workpieces. In the related art, an RGV feeding vehicle and a lifting workpiece need to enter and exit in a zinc pot zinc smoke recovery cover by means of longitudinal and transverse double tracks, so that in order to adapt the RGV feeding vehicle to move out of the zinc pot zinc smoke recovery cover along the track of the discharging direction, a track slit is arranged at the track position of a transverse sliding door, and a seam and an transposition machine are arranged on the top cover of the zinc pot zinc smoke recovery cover.
