Handling facilities of the present invention are using positive pressure dilute phase pneumatic conveying, by transportation system starting point blower as gas source, to
Conveying high-pressure air in system, after driving material to reach system end, material falls into storage equipment, and conveying gas is into deduster (the
One deduster 25 or the second deduster 45) purification be discharged into atmosphere.This law is suitable for inviscid granular material, and device structure is more
Stablize, failure rate is low, is particularly suitable for the conveying of polyvinyl chloride.But since polyvinyl chloride powder mobility is general, melting temperature compared with
Low, 80 DEG C -85 DEG C discolorations of decomposing, 185 DEG C are plasticized, and are very easy to that plugging, denaturation, this hair occurs in transmission process
The technical solution of bright proposition will solve the problems, such as this；
The delivery pipe 1 of handling facilities is divided for inner and outer pipes in the present invention, and inner tube walks material, and outer tube, which leads to auxiliary gas, carries out inner tube material
Dredging or cooling, this is realized by the unidirectional unlatching stomata on inner tubal wall, and when interior pipe choking, air flue 5 is inflated, air flue 5
Positive pressure opens one-way pneumatic valve, and inner tube air inlet is dredged or cooled down to blockage；5 gas source of air flue is that (first removes deduster
Dirt device 25 or the second deduster 45) exhaust outlet, the tee tube of deduster (the first deduster 25 or the second deduster 45) exhaust outlet
And pneumatic gate valve enables deduster (the first deduster 25 or the second deduster 45) exhaust pathway to convert, when delivery pipe 1 is normal
Situation downtake inlet close, deduster (the first deduster 25 or the second deduster 45) exhaust enter atmosphere；When delivery pipe 1
When needing to lead to auxiliary gas, the first gate valve 17 is opened, closes the second gate valve 18, deduster (the first deduster 25 or the second dedusting
Device 45) tail gas enters air flue.Pressure transmitter 34 and temperature sensor 35 inside delivery pipe 1 monitor inner tube pressure and temperature
Degree and is determined as putty when inner tube pressure is greater than 0.8kPa, at this time pressure transmitter 34 make deduster (the first deduster 25 or
Second deduster 45) tail gas enters air flue and dredged；When inner tube temperature is greater than 65 DEG C, that is, it is determined as that temperature is excessively high, it is warm at this time
Degree sensor 35 is opened aerial cooler 22 by controller, and transportation system supplies cold air, is cooled down to material；
Since container is different from general wagon, length is long and loading hatch is in tail portion, therefore common charging apparatus is difficult to
Material is sent to depths in container, or is lifted container tail portion with lifting platform, makes the material positioned at container tail portion
Internal container is slid into gravity, which increase the construction difficulty of charging apparatus, also increase task difficulty；Dress of the invention
Material injection apparatus can solve this problem；
Polyvinyl chloride material is after discharge duct 44 is transported to feed pipe, blows through rotary valve blanking, then through high pressure blower 24
Into internal container, present embodiment mesohigh blower 24 uses ss304 type, and 20 forty equivalent unit 40 loading times are 30-
45min/ vehicle, the loading of freight waggon >=17t/ vehicle, entrucking are high-efficient.
Discharge process is to improve discharge rate, is lifted container head using tipper 41, material is sink to container tail
Portion carries out discharging from tail portion；Blanking pipe 42 is three, further speeds up discharge rate；
Material compared to the process of charging conveys from high to low, and discharge process is the transfer feed bin 38 by being located at lower
It being conveyed at the top of the discharge bin 40 to hoist, discharging conveying needs bigger power, and conveying wind-force is bigger, so to pipeline in system
It rubs bigger, it is easier to generate the obstruction of delivery pipe 1 and fever；To solve this problem, the present invention proposes further solution:
Pressure transmitter 34 is connected with rotary valve 26, when 44 inner tube pressure of discharge duct is greater than 0.8kPa, controls rotary valve
Slow down, reduces feeding speed, avoid plugging；
Since conveying circuit is from 38 horizontal feed of transfer feed bin in device for discharging, midway is delivered up to discharge bin
40 top sides turn again to the route to horizontal feed to 40 center of top of discharge bin, thus discharge duct 44 is bent；Material is defeated
During sending, the material of high speed conveying is turned in bending part, curved in discharge duct 44 due to inertia fast ram tube body
Folding part is very easy to that plugging occurs and temperature of charge increases, and to avoid this case, 44 bending part of discharge duct is circle in the present invention
Arcuation pipe, the arc radius are 30-35 times of 44 diameter of discharge duct, reduce 44 pipe bent position curvature of discharge duct, and then reduce material
The shock that tube body is generated when turning.
