Preferably, the compressed gas flow tube is connected with air compressor by pipeline, and the pipeline is equipped with valve, is used for
Air-flow is controlled.
The broken material device being used in PVC drying processes of the utility model, PVC materials are sent by the hopper of screw conveyor
Enter screw conveyor, screw conveyor send material to gas flow tube, distinguished and admirable is sent material by gas flow tube by what air blower was sent
Enter airstream drying tower to be dried, the broken material device for being arranged on pneumatic conveying drying top of tower starts, to containing the knot of wet PVC materials
Block crushes segmentation, and the compressed air in compressed gas flow tube first is sprayed by nozzle and material block is split, the object of decline
Expect that the agitator arm for continuing through agitating device is stirred to achieve the purpose that further to crush, it is excessive super so as to avoid material block
Go out the ability of wind model, rest on air-flow tower bottom, and then reduce the PVC of super foreign particle, ensure that the quality of PVC.
The broken material device of the utility model bonds loose dough for being pressurized, by the dispersible material of slight impact have compared with
Good separating effect, which is the power drive being combined by compressed air and electric mixing device, and compressed air passes through
Nozzle sprays compressed air, effectively segmentation material block, and by agitating device, constant collision segmentation achievees the purpose that broken.
