And steel wire, cracking oil gas enter oil water separator and carry out later processing operation, the cracked residue quilt that cracking black carbon and steel wire are formed
The first-level transport mechanism for extending to pyrolysis furnace continuously exports：Screw shaft rotates under the drive of motor, and cracked residue is defeated forward
It send, small solid matter is discharged by the gap between screw shaft and spiral shell rib in cracked residue, big solids in cracked residue
Matter passes through the extruding to spiral shell rib so that the free end compressive deformation of spiral shell rib, big solid residue is under the deformation force effect of spiral shell rib
It is ejected, avoids that the solid impurity in cracked residue is stuck by first-level transport mechanism and burn out motor, and cracked residue passes through company
It takes over and enters machine barrel, realize the first-level transport of cracked residue；
(2) two-stage conveying：The cracked residue for reaching machine barrel realizes two-stage conveying under the action of secondary conveyor：It splits
Big solid matter is discharged in first-level transport in pyrolysis furnace in solution residue, and small solid matter is in screw rod in cracked residue
Cracked residue is delivered up by the rotation of axis, is discharged by the gap between screw shaft and spiral shell rib, is avoided cracked residue by spiral shell
Bar axis is stuck and burns out motor, and when secondary conveyor moves, cooling water is passed through by cracked residue into machine barrel by water inlet pipe
Temperature by 500 DEG C or more rapid coolings to 100 DEG C hereinafter, cooling water is discharged by outlet pipe, the cracked residue quilt after being cooled
Secondary conveyor is delivered continuously in material storing box.
Compared with prior art, the present invention have certain gap between spiral shell rib and screw shaft, the fixing end and screw rod of spiral shell rib
The left end of axis is welded to connect by welding block, and the free end of spiral shell rib uses the structure of compressible deformation, when consolidating in cracked residue
When body impurity passes through screw shaft, it can be discharged from the gap between spiral shell rib and screw shaft, it is stuck by screw shaft to avoid solid impurity,
To burn out motor, cracked residue is caused not export continuously；It, can not be from spiral shell rib and screw rod if the volume of solid impurity is larger
When being discharged between axis, big solid residue can be by the free end compressive deformation of spiral shell rib, in the effect of spiral shell rib free end deformation force
The lower solid residue that volume is larger pops up screw shaft, to realize the serialization conveying of cracked residue；Its agent structure is simple,
Low manufacture cost, operational and highly practical, use environment is friendly.
Description of the drawings：
