Principle of work of the present invention is described as follows:
When powder material a bit being transported among d, e, the f certain when some by in a, b, the c point certain, the pressure-bearing two-way valve 19 and 20 that is positioned at this some place is opened, and this point is communicated with transfer line.Then start the close phase powder material of positive negative pressure combined type Pneumatic conveyer, after this device starts, close first pipeline valve 1 and open into white butterfly valve 3, make malleation carry the powder delivery closedown of pipeline of sending warehouse 2 and be communicated with negative pressure transportation receiving bin 7.Start vacuum generator 10, make negative pressure transportation receiving bin 7 and malleation carry sending warehouse 2 to produce simultaneously negative pressure.Communicate the powder material at a place with powder inlet pipe road 18 under the combined action of the gentle powder mixing value of this negative pressure (not shown), be transported in the negative pressure transportation receiving bin 7 by pipeline 18, then, powder material drops in the malleation conveying sending warehouse 2 through advancing white butterfly valve 3 under action of gravitation.The air that together enters in the negative pressure transportation receiving bin 7 with powder material passes through pocket type air filter 14, is taken away by vacuum generator 10, and the dust that this part air is carried secretly is filtered out by pocket type air filter 14.Pocket type air filter is after 14 work a period of times, the part latch up phenomenon can occur in its filtering micropore, filter efficiency is descended, for this reason, a pressurized air blowback tracheae 13 is housed above each pocket type air filter opening, this blowback tracheae interval certain hour circulation is carried out independent blowback to each filter, disposes to attach at pocket type air filter 14 lip-deep dust, to guarantee the efficient of filter.When the height of the powder material in malleation is carried sending warehouse 2 reached near the position at sending warehouse level sensor 4 places, sending warehouse level sensor 4 sent signal, advances white butterfly valve 3 and closes, and negative-pressure conveying system works on.After advancing white butterfly valve 3 and closing, compressed air inlet valve 6 is opened, carry sending warehouse 2 to be filled with clean pressurized air to malleation, when the pressure in malleation is carried sending warehouse 2 reaches setting value, malleation carries powder and the pressurized air in the sending warehouse 2 to mix more fully, this moment, the opening conduits valve 1, and malleation carries the powder compact material that has in the sending warehouse 2 will enter into along powder delivery pipeline 17 the point of delivery place of appointment.Certainly, on powder delivery pipeline 17, also need as positive Pressure Transportation System some gulp valves are set like that, simultaneously also can carry the lower end of sending warehouse 2 that some mass transport state control cock are set in malleation, with realization the feed status of powder material be controlled.After powder material in malleation is carried sending warehouse 2 has all been carried, malleation carries the pressure in the sending warehouse 2 to return to gradually atmospheric pressure state, at this moment, close pipeline valve 1, then open into white butterfly valve 3, malleation carries the air in the sending warehouse 2 to see through the top that negative pressure transportation receiving bin 7 interior powder materials enter into negative pressure transportation receiving bin 7, then, after 14 filtrations of pocket type air filter, taken away by vacuum generator 10 again.Pressure in malleation is carried sending warehouse 2 and the pressure in the negative pressure transportation receiving bin 7 near the time, powder material in the negative pressure transportation receiving bin 7 falls under gravity into malleation and carries in the sending warehouse 2, in the time of near the controlling level in the malleation conveying sending warehouse 2 reaches its level sensor 4 again, this level sensor sends signal, and malleation carries sending warehouse 2 again to carry out the malleation conveying operations.This continuous negative pressure transportation operation is made up with malleation conveying operations intermittently, has realized by the powder material conveying operations of multiple spot to multiple spot.In general, the speed that the powder malleation is carried is more much higher than negative pressure transportation speed, malleation carries the used time very short, the volume of receiving bin level sensor below 15 of negative pressure transportation receiving bin 7 designs enough greatly simultaneously, after advancing white butterfly valve 3 and closing, malleation carry sending warehouse 2 carry out the malleation conveying operations during this period of time in, enter into the position at powder material out of reach receiving bin level sensor 15 places in the negative pressure transportation receiving bin 7, negative-pressure conveying system is continuous working.But when positive Pressure Transportation System goes wrong, the time of positive pressure operation may be excessively normal, so that the powder material in the negative pressure transportation receiving bin 7 reaches the position at receiving bin level sensor 15 places, at this moment, receiving bin level sensor 15 sends signal, and the negative-pressure conveying system shut-down operation is in order to avoid the powder material that enters in the negative pressure transportation receiving bin 7 is too much, damage negative-pressure conveying system, this also is the effect place of receiving bin level sensor 15.
