Embodiment 2
It is given up using described disassembled using the disassembly system that ionic liquid disassembles useless circuit board and recycles scolding tin in embodiment 1
Circuit board and the system recycling tin-soldering method for recycling scolding tin, include the following steps:
Step 1: the first filter cage 2 being hung in the heating tank 1, ionic liquid is then added to the heating tank
In 1, heats ionic liquid and maintain 230-270 DEG C；
Step 2: will be put by the useless circuit board of deashing in four positions of the rotation cage 3, and ensure each position
In useless circuit board amount it is suitable, keep system spin balancing；
Step 3: the rotation cage 3 for filling useless circuit board is hung in into heating tank 1, and the fixed heating tank 1, the rotation
Rotating cage 3 and the first filter cage 2；
Step 4: starting motor, maintaining 3 revolving speed of rotation cage is 15-60rpm, residence time 10-20min；Fusing
Scolding tin sinks to 1 bottom of heating tank and flows into the moving collection basin 113；Size is less than the filter pore size of the rotation cage 3
The porous plate of side wall and bottom surface of the component through the rotation cage 3 enter the first filter cage 2, wiring board and size are greater than institute
The component for stating the filter pore size of rotation cage 3 then stays in 3 in the rotation cage；
Step 5: closing speed regulating motor, the rotation cage 3, which is driven a vehicle, hangs in the cleaning device for filling ejected wash water progress
Cleaning.It cleans after finishing through traveling crane to discharge zone, takes out wiring board and larger-size component in the rotation cage 3.
Step 6: the electric heating tube 104 is closed, after ionic liquid temperature is reduced to 150-180 DEG C, by ionic liquid
It is evacuated to the ionic liquid temporary tank 4 by drain pipe 114 to keep in, first by the first filter cage after ionic liquid all exhausts
2, which hang in the rinse bath 5, is cleaned, cleaning finish after through traveling crane to discharge zone, take out described first filter in cage 2 size compared with
Small component then takes out the scolding tin in the moving collection basin 113.
After wherein step 2-5 is repeated 10 times, then carry out step 6.
By using the disassembly system and method for useless circuit board according to the present invention, after being disassembled, discharging is broadly divided into
Three parts: scolding tin, component, the wiring board without component.Component dismantling rate is more than 98%, the scolding tin rate of recovery 91%.Together
When, temperature range can be accurately controlled using ionic liquid as thermal medium, avoid pollution the release of object.
