First consult Fig. 1, Fig. 1 is that the utility model supplements zinc liquid device schematic diagram.Hold zinc liquid in galvanizing kettle 1, treat that zinc-plated workpiece is dipped into the operation wherein completing galvanizing; Zinc melting pot 2 is for melting zinc ingot metal; One end of upflow tube 3 is connected with zinc melting pot 2, and the other end connects galvanizing kettle 1.For ease of the flowing of zinc liquid, mode shown in Fig. 1 of upflow tube 3 can being pressed connects galvanizing kettle 1 and zinc melting pot 2 with certain inclination angle.
Galvanizing kettle 1 and zinc melting pot 2 can adopt the type of heating such as coal, coal gas or electricity, adopt Electric heating in this example, and zinc melting pot is using resistive band as Heating element, and galvanizing kettle adopts copper strips ruhmkorff coil as heating unit.For monitoring and controlling liquid temperature, galvanizing kettle 1 and zinc melting pot 2 are also provided with temperature measuring equipment and temperature control device usually, such as, thermopair, thermoelectric thermometer, infrared thermometer etc. can be adopted as temperature element, the control temperature such as PLC and silicon controlled rectifier.Adopt thermopair as temperature measuring equipment in this example, adopting PLC to set Heating temperature is particular value, adopts the heating of SCR control resistive band, thus forms closed loop heater Controlling System.
Accompanying drawings 2 below, the attached structural representation that Figure 2 shows that galvanizing kettle 1.Galvanizing kettle 1 is made up of galvanizing kettle housing 11, induction coil 12, insulating cotton 13 and thermopair 14, galvanizing kettle housing 11 is by the rectangular structure of high-temperature corrosion resistance steel plate splicing, galvanizing kettle interior dimensions is determined according to the physical dimension of galvanized workpiece, between pot wall and galvanized workpiece, usually leave the safe distance of about 300mm.Ruhmkorff coil 12 presses close to galvanizing kettle housing 11 outer wall, and in this example, ruhmkorff coil 12 adopts winding copper strips to form annular, and ruhmkorff coil 12 is embedded in insulating cotton 13, and fixes with support and galvanizing kettle housing 11.Near galvanizing kettle housing 11 housing one end, thermopair 14 is being installed.
