Specific embodiment
As shown in Figure 1, cracking waste plastics heating device of the present invention, including the level-one cartridge heater 1 being obliquely installed, the level-one
Feed opening 2 is arranged in higher one end of cartridge heater 1, and lower one end passes through to be connected communicating pipe 3 with the import of second level cartridge heater 4,
Shut-off valve 15 is arranged in the junction of the communicating pipe 3 and the second level cartridge heater 4, and the top setting of the second level cartridge heater 4 is split
The escape pipe 16 of gas is solved, filter plate 5 is arranged in the level-one cartridge heater 1 and the junction of the communicating pipe 3.
The cracking waste plastics heating device further includes filter plate recoiling device, and the filter plate recoiling device includes compressed air
Bottle 6, the compressed air bottle 6 are connected in communicating pipe 3 by air hose 7, and air valve 13 is arranged on the air hose 7.
The filter plate recoiling device further includes that the flushing being arranged between the filter plate 5 and the level-one heating device is cut
Changing device 8.
First flapper 9, first activity are set between the flushing switching device 8 and the level-one cartridge heater 1
Baffle 9 can block or open the level-one cartridge heater 1 and the connection rinsed between switching device 8.
The side plate far from 2 side of feed opening is the second flapper 11 in the flushing switching device 8, described the
Two flappers 11 can upward sliding and one slag-drip opening 12 of lower section formation in the flushing switching device 8.
The upward curved baffle 10 of the connected arc in the bottom of first flapper 9, when first active catch
When plate 9 blocks the level-one cartridge heater 1 and the connection rinsed between switching device 8, the curved baffle 10 is in the mistake
An arc-shaped runner is formed between filter plate 5 and the slag-drip opening 12.
