The specifically used principle of the present invention：
Lifting cylinder 44 is shunk, and gas-liquid washer 1 is extracted from interior service sink 6, while separating pipe 2 is from annular service sink
It is extracted in 5.
Rotary fixing screw bolt 21 so that fixing bolt 21 is detached from threaded hole 18, then holds gas-liquid washer 1 toward turning over
Turn, fixing bolt 21 is tangled with link 20, promote gas-liquid washer 1 that horizontality is kept to fix.
Cover board 11 and pedestal 12 are opened, quartz wafer level is put into and is placed in groove 13；Then cover board 11 is covered,
Cover board 11 and pedestal 12 are sealed by fixation by bolt.
Unclamp link 20 so that vertical state is translated under gas-liquid washer 1, then rotary fixing screw bolt 21 is screwed into screw thread
In hole 18 so that gas-liquid washer 1 is in vertical stationary state.
Control lifting cylinder 44 declines, and gas-liquid washer 1 is dropped into interior service sink 6, while U-shaped separating pipe 2 exports
It drops into annular service sink 5.
Start motor 42, rotary shaft 4, turntable 3 is driven to rotate, so as to drive multigroup gas-liquid washer 1 in interior service sink 6
Rotation, tells in rotary course, and cleaning solution is imported by the drain blade 8 of arc from inlet opening 9 to be placed in groove 13, cleaning solution
It pours into, quartz wafer is cleaned, while start high pressure nitrogen supply system from the bottom surface and top surface for placing groove 13,
High speed nitrogen is entered from rotary joint 43 in rotary shaft 4, is entered back into hollow turntable 3, then is entered from each connecting hole 31
Into air induction hose 23, then enter in the gas main 10 on pedestal 12 from air induction hose 23, entered from connection flexible pipe 22
In gas main 10 in cover board 11, then come out respectively from the air admission hole 15 for placing 13 bottom surface of groove and top surface again, to quartz-crystal
The tow sides of piece carry out purge of gas, therefore, the dual mixing of cleaning solution and nitrogen are formd, to quartz wafer tow sides
It is carried out at the same time cleaning；Cleaning solution and nitrogen after cleaning are ejected along the tap 14 for placing 13 both sides of groove, are entered total
It in discharge pipe 16, enters back into separating pipe 2, is finally discharged in annular service sink 5；Promote the cleaning solution before cleaning and cleaning
Cleaning solution afterwards is detached in different service sinks, is isolated and is come, therefore will not be mixed use, before ensure that cleaning
The cleaning of cleaning solution.
After cleaning, gas-liquid washer 1 from service sink is extracted by lifting cylinder 44, continues nitrogen
Gas flushing, high speed nitrogen wash out the spot on quartz wafer surface and cleaning solution, do not need to, using high temperature evaporation, pass through nitrogen
The dried and clean that quartz wafer surface can be realized is rinsed at a high speed.
