39 and scraper 40 semi-liquid-like waste plastics raw material can be made to flow to scraper 40 along the drainage cover board 39 rotated with central axis 35
Place, by being arranged and semi-liquid-like can be given up with multiple scrapers 40 that central axis 35 rotates on one week of drainage cover board 39
Plastic raw materials are uniformly spread out, and prevent liquid waste plastics raw material in the accumulation of reaction kettle upper section, so that the liquid uniformly spread out
Waste plastics raw material can along reaction kettle 4 side wall is smooth and uniform underground current.
In the present embodiment, multiple groups film forming blade 41 is provided on the central axis 35 in reaction kettle under scraper 40, it is more
Component film blade 41 is arranged from top to bottom on central axis 35, and every group of blade 41 in blocks has multiple T shape blades 4101,
The side wall of T shape blade 4101 and reaction kettle 4 close to.As shown in figure 5, axially inclined setting of the T shape blade relative to central axis 35.
In addition, in the present embodiment, the T shape blade 4101 in each component film blade 41 joins end to end.Thus one, from top to bottom
Liquid waste plastics raw material when film forming blade 41 by the T shape blade 4101 rotated with central axis 35 by can rapidly be brushed anti-
Answer and form film on the side wall of kettle 4, formed film waste plastics raw material can transient evaporation at high temperature so that reaction speed
Fastly, high-efficient.Meanwhile because T shape blade 4101 is obliquely installed relative to central axis 35, when liquid waste plastics raw material along
T shape blade 4101 will not fall when flowing down because of gravity moment, but can be suitble to along inclined T shape blade 4101
Speed flows downward, this ensure that the conversion of liquid waste plastics raw material, it is therefore prevented that caused by the bottom for falling directly into reaction kettle 4
React insufficient.
