The purpose of this utility model can realize by following technical proposal: a kind of powder homogenizer, be arranged on the tower bottom of the reservior portion of depositing powder, the top in tower storehouse has opening, it is characterized in that, this homogenizer comprises the homogenizing pipe, air inlet pipe one and air inlet pipe two, described homogenizing pipe vertically is arranged on inside, tower storehouse, be provided with the top blast device that powder is blown into the homogenizing pipe under the homogenizing pipe, described top blast device is connected with air inlet pipe one, the periphery of above-mentioned top blast device be provided with some groups will around powder blow to the reflux of top blast device, described reflux is connected with air inlet pipe two and is provided with the operating valve that open in the gap, is equipped with main valve on air inlet pipe one and the air inlet pipe two.
In homogenization process, be fixing strong district in the middle of the tower storehouse, be fixing weak district all around, main valve on the air inlet pipe one is in open mode, make the top blast device be in gaseity all the time, aim at the homogenizing pipe from bottom to top and give vent to anger, powder moves from lower to upper along homogenizing pipe inside, from the ejection of homogenizing pipe top, fall by self gravitation again.Simultaneously, group number of being performed fighting by computer system control reflux and the time length of opening are opened every group of reflux circulation, powder around the top blast device is successively blowed to the center, again by central motion to the Ta Ku top, move in circles, reach the homogenizing purpose.
In above-mentioned a kind of powder homogenizer, described top blast device comprises some escape pipes one, and an end of escape pipe one is from the insertion of tower bottom of the reservior portion and the cloth shower nozzle is housed, and the other end is communicated with air inlet pipe one.Main valve during homogenizing on the escape pipe one is opened all the time, and gas is diverted in the some escape pipes one by air inlet pipe one.The cloth shower nozzle prevents that powder from falling into escape pipe one and causing obstruction.
In above-mentioned a kind of powder homogenizer, described reflux comprises the isocon that is circular arc, isocon is provided with several escape pipes two that inserts the tower storehouse, and the end of escape pipe two is provided with the cloth shower nozzle, and above-mentioned operating valve is arranged between isocon and the air inlet pipe two.Isocon on all refluxes all is communicated with air inlet pipe two, the working condition of reflux under the control of operating valve intermittently starting.Gas is diverted on the some escape pipes two by isocon and enters Ta Ku.
In above-mentioned a kind of powder homogenizer, described isocon circumferentially is provided with, form one with concentric circle-shaped of homogenizing pipe.Isocon on all refluxes is on the same circumference, be evenly distributed on the top blast device around.
In above-mentioned a kind of powder homogenizer, described escape pipe two forms several and concentric circle-shaped of homogenizing pipe.The escape pipe of circumference setting makes the backflow effect around the top blast device even, and a plurality of concentric circles can improve the backflow effect.
In above-mentioned a kind of powder homogenizer, the bottom of described homogenizing pipe is provided with one and is trumpet-shaped charging body, and the big end of charging body is towards escape pipe one, and small end is connected with the homogenizing pipe.The charging body makes things convenient for powder to be blown into the homogenizing pipe.
In above-mentioned a kind of powder homogenizer, the pneumatic dish valve of described operating valve.
In above-mentioned a kind of powder homogenizer, described homogenizer also comprises the dust-precipitator that is arranged on tower storehouse top open part.Dust-precipitator prevents that powder is blown the tower storehouse and pollutes.
Compared with prior art, this powder homogenization system can be according to powder s own situation and such environmental effects, can select to open the number of reflux, regulate the time that each reflux is opened time and each whole homogenizing at every turn, to reach best homo-effect.Homo-effect is good, can satisfy the quality stability to raw material, the requirement of chemical analysis stability well.Installation and removal are convenient, are difficult for causing gas leakage and weaken current rate, even in long term wear, cause some escape pipe two gas leakage, since separate between each escape pipe two, influence less.
