The specific embodiment
The work of negative pressure barrier system is divided into following several stages:
Phase I: pressure setting.
Be installed on the control system of barrier system top layer because adopt the PLC module controls, system pressure be provided with until satisfying the operating process demand according to the method for the INADD IB1 that changes PLC.
Second stage: pressure is regulated.
Open the negative pressure starting switch of negative pressure barrier system, the CPU (central processing unit) in the control system will collected and be sent to the pressure signal in the body of cabin by pressure sensor.CPU analyzes the pressure data of collecting, and regulates the frequency proportions of air intake blower fan and air-out blower fan, to reach the force value of setting.
Phase III: material imports into.
To be loaded with the material go-cart that needs material handling along moving on guide rail moves near the door.Move door switch (press button or floor push) in the startup; Cylinder drives to move to move to the top and is higher than the travelling bogie position; It is inner that the material go-cart is pushed into the negative pressure barrier system, moves door switch on restarting, and cylinder will drive to move and move to guide rail position downwards.Through the gathering hole on the visual window material go-cart is pulled to proper operation position in the cabin.
Quadravalence section: operation and dust suppression in the cabin.
From the material go-cart, need unload by material handling, carry out corresponding operating (sampling, weighing, mixing, packing etc.).Because the air intake purifier in the cabin picks up from the air-flow of external environment condition and gets into barrier system inside from the air intake cleaning system; The air-out cleaned air passes is discharged outdoor through air-out blower fan pipe special; Under this flow pattern; But the dust major part that the built-in function of negative pressure barrier system produces is adsorbed; Play anti-dust effect; In addition, the discarded object that produces in operation can be positioned over the discarded object passage.
Five-stage: material spreads out of.
After in the cabin, accomplishing relevant operating process; The material that can need transport disposing out of my cabin is positioned in the material go-cart; Again with track supreme the move door of go-cart when material is come in and gone out; Starting switch make move the door move up; To being higher than the material go-cart highly is that the material go-cart is pushed out to out of my cabin; Restart switch closes to close and moves door, accomplishes spreading out of flow process.
