Internal and external disturbance type mixing device and efficient stirring method

Abstract

The invention discloses an internal and external disturbance type mixing device and an efficient stirring method. The device comprises a barrel body driven by a motor and disturbance plates on the inner wall of the barrel body, a lifting stirring paddle penetrates through the upper end of the barrel body, the lifting stirring paddle comprises a stirring barrel with openings in the two ends and a spiral conveying rod arranged on the stirring barrel, and the first driving device drives the spiral conveying rod to rotate in the stirring barrel; and the spiral conveying rod rotates to convey the material at the bottom of the barrel body to the upper part of the barrel body along the stirring barrel or rotates to convey the material at the upper part of the barrel body to the lower part of thebarrel body along the stirring barrel. The method comprises the steps of internal stirring, vertical stirring and central collection stirring. The device has the advantage that the problem of uniformmixing of large-batch 3-8-tonnage high-density materials can be solved.

Description

technical field [0001] The invention relates to a mixing device and a stirring method, in particular to an internal and external disturbance type mixing device and an efficient stirring method. Background technique [0002] For some granular material production industries, such as plastic masterbatch, a larger batch size of more than 5 tons is required. The existing blending device adopts the mode of a motor plus a three-dimensional slurry. Due to the great resistance of a large amount of accumulated granular materials, it has a great impact on power. The requirements are very high, the angle between the resistance surface of the paddle and the direction of motion is much less than 90 degrees, and because the speed is very low, the paddle passes through the accumulated material, due to the poor fluidity of the material and the huge accumulation pressure, it cannot push the material, the paddle After it has passed, the materials are still in place, so the purpose of mixing ma...

[0002] For some granular material production industries, such as plastic masterbatch, a larger batch size of more than 5 tons is required. The existing blending device adopts the mode of a motor plus a three-dimensional slurry. Due to the great resistance of a large amount of accumulated granular materials, it has a great impact on power. The requirements are very high, the angle between the resistance surface of the paddle and the direction of motion is much less than 90 degrees, and because the speed is very low, the paddle passes through the accumulated material, due to the poor fluidity of the material and the huge accumulation pressure, it cannot push the material, the paddle After the past, the material is still in place, so the purpose of material mixing cannot be achieved.
