Air in the described air-introduced machine exhaust gas extraction pipe, the ducted air of blanking enters in the discharge duct by discharging in the steam vent, the inner certain negative pressure that forms of blanking pipeline and blast pipe, be convenient to the PVC compound and fall into the extruder hopper by loading hopper, the filtering material of filling in the space between hopper and the blast pipe can pass through air, can not pass through the PVC compound, thereby make in the air of air-introduced machine in exhaust gas extraction pipe and blanking pipeline, avoid the PVC raw meal is also discharged.
As preferably, the coaxial vertical layout of described blanking pipeline and blast pipe.
Blanking pipeline and the coaxial vertical layout of blast pipe are convenient to the PVC compound and are fallen along the blanking pipeline, are not easy to overflow from steam vent.
As preferably, described steam vent is opened on the sidewall of blanking pipeline along the axis direction of blanking pipeline.
Steam vent is used to discharge the air in the blanking pipeline, make the blanking pipe interior keep suitable negative pressure, the size of steam vent can not be excessive, otherwise, there is the PVC compound to overflow easily, also filter can be set on the steam vent, only the air in the blanking pipeline can enter in the blast pipe by filter and be extracted by air-introduced machine, and the PVC raw meal is trapped within the blanking pipeline.
As preferably, the top sidewall of described blast pipe is provided with air-vent, and this air-vent is connected to the air inlet of described air-introduced machine by pipeline.
Air-vent is arranged on the top sidewall of blast pipe, is convenient to the setting of air-introduced machine.
As preferably, described filtering material is the filter of annular.
The filter of annular is nested between blanking pipeline and the blast pipe, only can pass through air, can not pass through the PVC compound, thereby keeps having suitable negative pressure in blanking pipeline and the blast pipe, guarantees the smooth whereabouts of PVC raw meal.
As preferably, be open blanking port between the outer wall of the bottom of described blast pipe and blanking pipeline.
The PVC compound of being overflowed by steam vent is blocked in outside the filtering material, falls into the extruder hopper by blanking port.
As preferably, the bottom of described blanking pipeline has the extension that stretches out described blast pipe.
The extension of described blast pipe is stretched out in the bottom of blanking pipeline, when air-introduced machine is extracted the ducted air of blast pipe and blanking out, avoids the PVC compound is extracted out by the bottom of blanking pipeline.
But the utility model exhaust dustproof feeding device is put blast pipe by the blanking pipeline outer periphery at the PVC compound, and form negative pressure in blast pipe and blanking pipeline, being convenient to the PVC compound drops down onto in the extruder hopper, simultaneously, prevent flying upward of PVC compound, improve production environment.
Description of drawings
But Fig. 1 is the utility model exhaust dustproof feeding device partial sectional view.
The specific embodiment
Below in conjunction with accompanying drawing, but the utility model exhaust dustproof feeding device is done detailed description.
