3.Description of equipment
3.1 Workpieces feeding device
Commentary: The material is put into the elevator by hand. The
material is transferred to the hopper and reaches the set weight
(the value can be set to 0-200Kg). The hoist stops working. The
hopper waits for the drum to open the lid. After the drum lid is
opened, the hopper will be opened. The material is placed in the
drum.
3.2 Auto surface treatment unit
1. Each roller is driven independently, 15 revolutions per minute,
effectively and evenly allowing reagents to cover the surface of
the material.
2. The drum can be loaded with 200~250 kg at one time. After the
roller is lifted by the moving vehicle, it enters the next process.
3. Each corresponding tank body is equipped with sensors such as
liquid level and drum placement position to effectively control the
position and level control of the drum. Liquid level off the line,
position offset, etc. make an alarm.
3.3 Drying unit connection
After the drum is unloaded, it falls into the material lifting
machine, and the material is transferred to the drying equipment by
the elevator. The material vaporizes the surface liquid to reach
the surface after drying. The material is discharged from the
drying equipment and then conveyed by the lifting machine to the
weighing hopper. , After the hopper confirms the weight, it is put
into the bucket and waits for galvanization.
3.4. Automatic hot galvanizing equipment
1. Once the weight is confirmed with measuring hopper, the material
will be put into bucket
2. The trolley moves the bucket to zinc kettle, and the next bucket
will be moved accordingly.
3. The Rotary centrifugation arm moves and rotate the bucket on
line and unloading.
4. With cooling and passivation tank, after passivation, the pieces
will be transferred to packing.
4. Environment protection equipment
Zinc smoke collection cover, fan, bag filter unit
