In the mixing process, the mixing bin does not relate to a stirring structure, and the distribution of coarse powder and fine powder still has an uneven phenomenon for metal powder with larger particle size distribution. In addition, when the humidity of air is high, the moisture absorption capacity of the powder is enhanced, and particularly, the fine powder can absorb more moisture in the powder transfer process, so that the powder agglomeration phenomenon is obvious, the powder flowability is poor, and the phenomenon of serious oxygenation of the product can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming above not enough, provide a special multi-functional blendor to metal powder, especially humidity is low, the oxygen content is low, the mobility is good active metal's even compounding, can reduce metal powder's moisture, reduces its oxygen increment, improves its mobility, promotes the compounding degree of consistency and compounding efficiency, reduces the compounding time, and has improved metal powder compounding's safe operation's reliability and automaticity.
In order to realize the above-mentioned purpose, the utility model provides a multi-functional metal powder blendor, including being fixed in axis of rotation bipyramid type blending bunker and rotating-structure, connect inert gas air supply and gas storage bin on two awl sections of blending bunker respectively, install heating device on the blending bunker, install the agitator in the storehouse.
The agitator is arborescent stirring structure, arborescent stirring structure includes the stirring main shaft of being connected with external electric machine, is equipped with a plurality of stirring branch pieces on the stirring main shaft, is equipped with the stirring plectrum on the stirring branch piece. This arborescent stirring structure preferably adopts 304 stainless steel material, avoids introducing and mix with, and structural strength is big, can not produce the deformation. The blending bunker is rotating the in-process, and the agitator also can stir metal powder along with blending bunker simultaneous movement, and this arborescent stirring structure can realize the further even compounding of powder through plus motor adjustment rotational speed moreover. The agitator can be equipped with two, is located the conical surface inside two upper and lower awl section of thick bamboo phase pairs of mixing bunker respectively and makes the stirring more abundant, and the dispersion is more even.
Heating device makes the blending bunker realize the heating function in the pivoted, can be detached through the moisture in the heating effect metal powder to discharge in the air through the gas storage storehouse. The fluidity of the moisture-removing metal powder is increased and the oxygen-absorbing capacity is reduced, and the product can maintain a low oxygen level. The two heating devices can be arranged and are respectively positioned on the conical surfaces of the upper conical cylinder and the lower conical cylinder of the mixing bin, which are opposite to each other. The heating effect is better, improves the efficiency of removing damp.
Be equipped with first pneumatic valve on the pipeline that blending bunker and inert gas air supply are connected. And a second pneumatic valve is arranged on a pipeline for connecting the mixing bin with the gas storage bin, and a third pneumatic valve is arranged on a pipeline for discharging gas from the gas storage bin. The design of the inert gas source and the gas storage bin can effectively control the metal powder to be carried out in the inert gas protection, the reliability and the automation of the safe operation of metal powder mixing are improved, and especially the operation safety of active metal powder such as aluminum alloy and the like is improved. The design of pneumatic valve makes the blending bunker realize instant pressure release's effect after the superpressure, and concrete operation is as follows: before starting the mixer, opening a first pneumatic valve to fill inert gas into the mixing bunker from an inert gas source, opening a second pneumatic valve and a third pneumatic valve, and discharging air in the mixing bunker, the gas storage bunker and the pipeline through the replacement action of 5-10 min, so that metal powder is mixed under the protection state of the inert gas, and the pressure of the inert gas is generally 0.2-0.3 MPa. The inert gas displacement operation generally follows the principle of "bottom in and top out". And closing the first pneumatic valve, the second pneumatic valve and the third pneumatic valve after the replacement and exhaust are completed. And starting the rotating structure and the heating device of the mixing bin to start mixing operation. The rotation frequency is 5-8 r/min, and the heating temperature is 40-80 ℃. Because heating device's heating action, the gas in the blending bunker can appear the expansion effect, and gas pressure increases in the compounding process. The utility model can be designed to automatically open the second pneumatic valve for exhausting when the pressure of the mixing bin is more than 0.4 MPa; and when the pressure of the mixing bin is less than 0.2MPa, the second pneumatic valve is automatically closed. The discharged gas enters the storage bin for storage and can be used as the purge gas. When the pressure of the air storage bin is greater than 0.4MPa, the third pneumatic valve is automatically opened to exhaust air and enter air. In the whole process, air inlet and air outlet of the mixing bin, the air storage bin and the like are realized through the pneumatic valve and the electronic pressure gauge, and automatic and safe operation is realized.
The utility model discloses can all set up the manometer on blending bunker and storage silo to the pressure variation in real-time supervision storehouse.
The part of blendor not related to all be the same with prior art or can realize through prior art.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model further improves the mixing uniformity and mixing efficiency through the arrangement of the stirrer, and reduces the mixing time; the heating device can achieve the purpose of heating and dehumidifying while mixing the metal powder, thereby avoiding the situation that the metal powder with moisture is treated by an oven after mixing, improving the working efficiency, avoiding the situation of secondary oxygen absorption in the process of transferring the metal powder in the air, and achieving the purpose of high efficiency while ensuring the high quality of the product; the arrangement of the inert gas source and the gas storage bin further improves the reliability and the automation of the safe operation of metal powder mixing. This blendor simple structure can improve work efficiency and product quality, realizes safe operation.
