Technique Instruction
2.1. Air inlet processing system
- The air inlet damper is installed on the air hose for obtaining air directly from outdoors. It is equipped with 100 meshes stainless steel filter net, which opens with machine turning on and closes with machine turning off to avoid outdoor air entering.
- Primary and medium efficiency air inlet cabinets are made of stainless steel, equipped with quick-open door, which can install the air inlet filter efficiently, and differential pressure measuring connector to install the differential pressure gauge or sensor.
- It’s optional for primary and medium efficiency air inlet cabinets to be equipped with below item:
- Primary filter ceiling G4 level
- Medium efficiency filter ceiling F9 level
- Heater: it’s installed with steam heater or electrical heater in the hot air channel to heat the inlet air. The steam heater is equipped with PID control valve while the electrical heater with SCR silicon controlled electric governor to control the air inlet heating.
- Air inlet damper
2.2 Main machine
- The main machine can be divided into four parts: machine base, material tank, diffusion chamber and filter chamber.
- Machine base: it is located at the bottom of machine and equipped with head ring, which can rise and fall. At its both sides, two pneumatic cylinders are installed to lift up the material tank and lock the three parts of tank, diffusion chamber and filter chamber, one for each side; at its back, there is an air inlet connecting with air inlet damper. It’s also equipped with bottom drain valve, CIP cleaning gun connector, inlet air temperature connector, air blowing rate and speed measuring connector.
- Material tank: it ‘s placed on the movable carriage with four casters, installed with two sight glasses, adopting pressure-proof lens of 12Bar, material sensor connector and on-line sampling device.
- Diffusion chamber: installed with two sight glasses, adopting pressure-proof lens of 12Bar.
- Filter chamber: double compartment structure, installed with two sight glasses, adopting pressure-proof lens of 12Bar.
Equipped with anti-static filter bag frame to install two anti-static filter bags (bore diameter: 150meshes).
PLC controls pneumatic cylinder shaking two bags in turn.
2.3. Spraying system
- Equip with peristaltic pump to feed liquid.
- Liquid feeding trolley, 10L barrel with pneumatic stirring, three-flow top spray gun atomizer with 304stainless steel.
2.4. Exhaust system
- The filter chamber is equipped with two exhaust dampers
- The Y-shape exhaust pipe is equipped with outlet air temperature connector.
- Induced draft fan
- Silencer
- Exhaust pipe (N2)
2.5. Control system
- It’s equipped with operation cabinet, electrical and pneumatic control cabinet.
- The operation panel is installed on the stainless steel operation cabinet, 10 inch touch screen, human machine interface.
- PLC control
- LCD color button and emergency stop button
- All the other electrical appliances and pneumatic components are installed in the stainless steel control cabinet.
- Monitor and control the Max/min value of operating parameters.
- The PID software is carried out inner PLC and its parameters are defined by each control operator.
- Alarm for the Max/Min value of single operating parameter as below:
- When the compressed air doesn’t satisfy the setting value, lock the other operations and alarm under working condition.
- When any part of this machine not in right place, lock the other operations and alarm under working condition.
- Lock the falling of material trough under normal operating status.
- When the pressure of compressed air for atomizing becomes low, stop feeding liquid automatically / alarm.
- For any error of system, the alarming message will display on the screen and flicker with red frame.
- When operating the help file, it will display more detailed information to help the operators know about the machine system faster to reduce the operating mistakes.
2.6. Parameters--can be set & measured by this equipment and controlled by PID
- Air inlet capacity: it can be measured by air quantity sensor & transmitter and draught fan transducer, auto-controlled with PID (optional) according to setting value.
- Air inlet temperature: it can be measured by temperature sensor and auto-controlled with PID according to setting value.
- Atomizing pressure: ①regulate it by manual reducing valve and display it by pressure gauge.
2.7. Parameters-display in operational process
- The blowing rate can be set and adjusted precisely by transducer; usually we use the unit of HZ to measure the speed of draught fan.
- The inlet air temperature can be set and displayed as xxx℃, with the fluctuation range of±2℃.
- The material temperature can be set and displayed as xxx℃, with the fluctuation range of±1℃.
- Can display the exhaust temperature as xxx℃ and set the final drying temperature.
- Can set and display the bag-shaking time in sync. xxx sec
- Can set and display the bag-shaking time out of sync. xxx sec
- Running time
