Embodiment Construction

[0018] The continuous mixing method of the powdery material in this embodiment is a combined mixing mode of two-stage mechanical agitation to break the agglomerate and one-stage pneumatic homogenization. Combined mixing method is that the materials that enter the mixing device at the same time in proportion are continuously passed through the first-stage mechanical agitation and broken-agglomeration mixing, the second-stage mechanical agitation and broken-agglomerate mixing, and the bottom pneumatic homogenization and mixing from top to bottom according to gravity. Complete the mixing process.

[0019] see figure 1 , figure 2 and image 3 , the structural form of the powdery material continuous mixing device in the present embodiment is:

[0020] The mixing device is set as a vertical structure, and the collecting hopper 1 for feeding two or more powdery materials is set on the top of the mixing device, located below the collecting hopper 1 and in the same center On the a...

Abstract

The invention discloses a continuous mixing method and device for powdery materials. The invention is characterized in that: a combined mixing mode combining a two-stage mechanical agitated bulk-breaking mixing mode and a primary pneumatic homogenized mixing mode is adopted; and the combined mixing mode is as follows: materials which are simultaneously fed into a mixing device in proportions are sequentially subjected to first-level mechanical agitated bulk-breaking mixing, second-level mechanical agitated bulk-breaking mixing and bottom pneumatic homogenized mixing in accordance with the gravity thereof from top to bottom so as to complete a mixing process. According to the invention, through the organic combination of mechanical mixing and pneumatic homogenized mixing, the mixing effect is good; and the mixing device is of a vertical structure, therefore, the mixing device is small in floor space and flexible in process arrangement.

Description

technical field [0001] The invention relates to a continuous mixing method and device for powdery materials. Background technique [0002] At present, most of the powder material mixing equipment used in domestic and foreign enterprises are horizontal mixers or spiral vertical mixers. The working principle of the horizontal mixer is to mechanically stir the powdery materials through the blades set on the transmission shaft, based on the circular movement and axial movement of the materials, so as to achieve the purpose of mixing. The horizontal mixer is installed horizontally. It needs enough power to overcome the resistance of the material during the working process. There are problems such as large installed power, high energy consumption, low production efficiency, large floor space and poor process layout flexibility. Vertical mixers are mostly multi-shaft driven spiral conical mixers. Due to its own structural limitations, the vertical mixer is prone to dead angles, d...
