Embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, a kind of waste plastics decomposition heater, it includes feed screw, spiral
The outer cover of cell body 1 of feeder is equipped with heating jacket 2, and the one end of heating jacket 2 is provided with heating liquid-inlet 2-1, the other end is set
Heating liquid outlet 2-2 is equipped with, the heating liquid here used is high-temperature molten salt liquid, on the helical axis 3 of feed screw
Blade is the oar blade type helical blade 4 of each three interruptions being evenly arranged of pitch, and each pitch neutral of helical axis 3 is provided with
Stirrer gear 5, stirrer gear are conical tooth, and stirrer gear 5, which is evenly arranged between adjacent two panels oar blade type helical blade 4 to be formed, to be staggered
Arrangement, the back side of oar blade type helical blade 4 are provided with two pieces of gussets 6, promote resistance larger because plastics convey, are protected plus gusset 6
The firm of blade is demonstrate,proved, the upper end of cell body 1 of feed screw is provided with cracked gas outlet 7, entered from the charging aperture 8 of feed screw
Waste or used plastics in cell body 1 decomposite hydrocarbon gas under the high-temperature heating of high-temperature molten salt liquid, and 7 rows are exported from cracked gas
Go out, the discharging opening 9 of feed screw discharges residue, is transferred to next procedure.
The both ends of helical axis 3 connect bearing block 10 respectively, and bearing chuck 25 is also set with bearing block 10, is opened on bearing block 10
There are cooling water inlet 21 and coolant outlet 22, bearing block 10 can be cooled down, in addition, connecting in rotary shaft 3 and bearing 23
The inside for connecing the axle of section is provided with an elongated hole, is cooling water circulation inside elongated hole, cooling water by swivel joint 24 cooling water inlet
11 enter, and are flowed out by coolant outlet 12, the inner ring of bearing 23 and outer ring contact position are all cooled, to ensure that bearing will not surpass
Temperature damage, ensures equipment normal operation.Heat-insulation layer 13 is installed, it is possible to achieve heat insulation effect, improved outside heating jacket 2
The efficiency of heating surface.
The lower end thereof of heating jacket 2 is fixedly connected with bracket 15 by fixed support 14, and the bottom other end of heating jacket 2 passes through
