Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of powder drying system of the utility model includes：
Kettle 3 is dried, the drying kettle 3 includes feeding pipe and discharging pipeline；
Infrared electric heating device 2, the infrared electric heating device 2 are located on the outer wall of the drying kettle 3；
Agitating device, the agitating device are built in the drying kettle 3；
Vacuum extractor, the vacuum extractor is connected with the drying kettle 3 by vacuum-pumping pipeline, described to vacuumize
The receiving tank 11 that pipeline is equipped with condenser 10 and is communicated with the condenser 10.Because it is de- for high temperature to dry the powder in kettle 3
Water, then the steam temperature that vacuum extractor is extracted out is too high, so a condenser 10 is set on vacuum-pumping tube road, it will be high
Temperature steam is condensed into water, is then temporarily put in receiving tank 11.In addition, receiving tank 11 is additionally provided with liquid level gauge, it can be according to actual conditions
It is drained.
In the above-mentioned technical solutions, powder is knocked down into drying kettle 3, the heat that infrared electric heating device 2 generates is by powder liter
Temperature.After powder reaches preset temperature, powder evaporates moisture under high temperature environment, and agitating device starts, and powder is turned over up and down
It is dynamic, so that powder is heated evenly, vacuum extractor is carried out at the same time with agitating device, and vacuum extractor vacuumizes drying kettle 3,
The high-temperature vapor dried in kettle 3 is extracted out by vacuum-pumping pipeline, realizes powder drying, because vacuum-pumping tube road is equipped with condensation
Device 10 and the receiving tank 11 communicated with condenser 10, high-temperature vapor are condensed into water in condenser 10, are temporarily stored into receiving tank 11.
In above-mentioned powder drying system, for drying kettle 3, infrared electric heating dress, agitating device and vacuum extractor into
Row is described in detail.
As shown in Figure 1, drying kettle 3 includes feeding pipe and discharging pipeline, feeding pipe and discharge nozzle road are respectively equipped with
Inlet valve 6 and outlet valve 1.In the present embodiment, by adjusting inlet valve 6, powder is sent into drying kettle 3, powder through feeding pipe
It can be sent by manually throwing the form of powder.It is also provided with electronic scale 4 on drying kettle 3.After powder is dried, discharged by adjusting
Valve 1 shifts powder.Drying kettle 3 can also further be connected with nitrogen pipeline, and nitrogen pipeline is equipped with nitrogen valve 5, when drying kettle
After 3 are vacuumized, drying nitrogen pressure release is supplemented in drying kettle 3 by adjusting nitrogen valve 5.
Infrared electric heating device 2 can be made of several infrared silicon carbide electric boiling plates, infrared silicon carbide electric boiling plate fitting
In the outer wall of drying kettle 3, powder is heated up by infrared electric heating, wherein carbon powder is warming up to 150 DEG C, and Paris white is warming up to
200℃。
Agitating device includes stirring motor 7 and the stirring blade that is connect with stirring motor 7, and stirring blade includes spiral shell clockwise
Band and ribbon counterclockwise.When powder reaches preset temperature, the stirring blade of drying kettle 3 starts to stir, and powder is stirred up and down, is made
Its thermally equivalent is heated to the moisture evaporation of powder when certain temperature, and at the same time, vacuum extractor starts simultaneously, to drying
Kettle 3 is vacuumized.In the process, it is carried out at the same time due to stirring and vacuumizing, can make powder dehydration equal to greatest extent
It is even, by adjusting vacuum valve 8, the moisture that powder is evaporated under high temperature environment is taken away by vacuum-pumping pipeline, to
Realize powder drying.
As shown in Figure 1, the high-temperature vapor in drying kettle 3 by vacuum extractor such as vacuum pump 12 siphons away that baking is discharged
Dry kettle 3.To avoid taking powder away simultaneously, filter can be equipped with by being located between vacuum extractor and drying kettle 3, and filter is by powder
It intercepts, and by 9 blowback of Pulse anti-blow device positioned at vacuum-pumping pipeline and 3 junction of drying kettle, the powder being attached on filter core
Material blows open and recycles continues drying in drying kettle 3.Pulse anti-blow device 9 can carry out blowback by nitrogen to it.
The operation principle of above-mentioned powder drying system is：
Drying kettle 3 is communicated with feeding pipe, and by adjusting inlet valve 6, powder send drying kettle 3, powder through feeding pipe
It can be sent by manually throwing the form of powder, then start infrared electric heating device 2, powder is made to be warming up to technique required temperature；So
Start stirring motor 7 afterwards, driving stirring blade (including ribbon clockwise and ribbon counterclockwise) stirs the powder in powder cabin, makes powder
Material stirs up and down, powder moisture evaporation, while vacuum extractor such as vacuum pump 12 siphons away the moisture being evaporated.Due to vacuumizing
When, powder can be inevitably pumped into vacuum pipe by condition of high vacuum degree, so one Pulse anti-blow device 9 of setting, what is pumped up
Powder is returned with nitrogen blowback in drying kettle 3.After powder dehydration reaches technological requirement, using vacuum intake or other forms handle
The equipment that powder is transferred to other storage powders such as blender or cooling reactor from discharging pipeline.
Tradition drying is dried for the whole packet of powder is put into baking oven, and powder accumulation keeps powder packet internal anhydro uneven, tradition
Baking oven baking powder efficiency is low, and energy consumption is big, and dehydrating effect is general, under traditional stoving process, powder is put into baking oven and is toasted 1~2 day
Time, carbon powder water content reach 1000PPM, calcium carbonate water content 300PPM.And the powder drying system in the utility model,
It is heated by infrared electric heating device 2, coordinates agitating device and vacuum extractor, taken out while stirring using under high temperature environment true
Empty form makes powder dehydration evenly, and 90 minutes time can make carbon black water content be reduced to 800PPM (carbon powder heating
To 150 DEG C), calcium carbonate water content is reduced to 170PPM (calcium carbonate is heated to 200 DEG C), greatly improves production efficiency and takes off
Water effect.In addition, the manufactured polyurethane adhesive after the powder drying system in the utility model dries powder, the resting period is much larger than biography
Baking oven of uniting dries the resting period of powder, and the dehydrating effect for having benefited from powder drying system is excellent.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
Modification or replacement, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
