It is mobile, pass through below the heating board 21 of heater box 2, the heat that heating board 21 issues preheats workpiece, convenient for subsequent
Zinc processing is soaked, the effect of leaching zinc is improved, improves working efficiency;Conveyer belt is steel band, and steel band is wear-resistant, high temperature resistant, service life
It is long, meanwhile, steel band thermal conductivity is good, improves the effect of preheating, and the conveyer belt of rotation stirs the liquid in pre- heat channel 1, improves pre-
The liquid of heat channel 1 improves the cleaning effect to conveyer belt to the cooling effect of conveyer belt;At the same time, the heat of heating plate
The liquid in heater box 2 is set to heat up, being warming up to boiling by liquid makes the bubble generated, and push elastic helix plate 22 to shake, into
One step stirs liquid, increases the temperature Quick uniform of liquid in heater box 2, adds to the zinc liquid in leaching zinc furnace 3
Heat, time needed for reducing the heating of zinc liquid improve working efficiency;When the air pressure that the boiling of case internal cause generates reaches pressure sensor
When the influence value of setting, controller is fed back to, to open check valve, is passed through hot steam in zinc liquid, adds zinc liquid in lower part
While hot, top zinc liquid is also heated, improves the rate of heat addition, improves working efficiency;When zinc liquid is warming up to certain journey
When spending, the workpiece after preheating is sent into zinc liquid by handgrip 6 carries out leaching zinc processing.
