A complete hanging rod silica sol drying line usually includes the following systems:
1. Suspension conveyor system
(1) Core: A closed circular track typically made of sturdy steel structure.
(2) Hanging pole: a metal pole that spans over a track and can move with a chain. This is the origin of the name 'hanging pole style'.
(3) Lifting device: a hook or bracket suspended from a hanging rod, used to carry a coated mold shell (or wax mold tree).
2. Drive and tensioning system
(1) Drive device: provides power for the entire conveyor system and controls the operating speed of the production line.
(2) Tensioning device: Maintain appropriate tension on the conveyor chain to prevent slipping or derailment.
3. Environmental control system (dry core)
(1) Temperature and humidity control system
This is the 'brain' of the drying line. Accurately control the temperature and humidity in the drying area through air conditioning, heaters, humidifiers, dehumidifiers, and ventilation systems.
(2) Air supply and circulation system
Ensure uniform air flow in the drying area, avoid dead corners, and ensure consistent drying conditions for all molds.
4. Shell (box body)
A large box structure that encloses the entire drying area, typically constructed from insulation panels such as color steel sandwich panels, to maintain internal stability and save energy.
5. Control system
(1) PLC (Programmable Logic Controller): The core of automation control, responsible for coordinating the setting and maintenance of conveyor speed, temperature, and humidity.
(2) Human Machine Interface (HMI): Touch screen, convenient for operators to set and monitor drying process parameters (such as temperature, humidity, running time, etc. in various areas).
