Material distribution device and method

Abstract

The invention provides a material distribution device and a method. In the material distribution device, a distributor main body comprises a barrel; a rotating paddle is arranged in the barrel; a discharging port is formed on the bottom of the barrel; a first feeding device is arranged for conveying a first material into the barrel from a first feeding channel; a second feeding device is arrangedfor conveying a second material into the barrel from a second feeding channel; a torque difference exists between the torque of the first material acting on the rotating paddle and the torque of the second material acting on the rotating paddle; the rotating paddle can rotate under the effect of the torque difference. A driving mechanical stirring device is avoided; structure is simpler and working is more stable and efficient; the material distribution device is suitable for various materials, is capable of realizing continuous distribution and mixing of materials and does not result in interior overheating; when rotating speed is lower, a driving device can be utilized to supply power for assisting the rotating paddle in rotating; when material flow is smaller, the material still can beuniformly mixed; the material distribution device can be used for micro-layer distribution and mixing of materials at any material flow ratio.

Description

technical field [0001] The invention relates to the technical field of batching, in particular, to a material distribution device and method. Background technique [0002] Material mixing is an indispensable link in the production and manufacturing of many industries, such as modified plastics industry, food processing industry and chemical products. The uniformity of material mixing directly determines the quality and stability of the product, and the production raw materials often have multiple components with different proportions, shapes and particle sizes, and it is difficult to mix them uniformly during mixing. If it is stirred and mixed manually, the workload is very large, the labor intensity of the operator is high, and the effect of material mixing is not ideal. [0003] At present, the mixing equipment is mainly based on various mixing forms. Commonly used are: high-speed mixer, low-speed mixer, horizontal mixer, double-helix conical mixer, gravity-free mixer and...

AI Technical Summary

Problems solved by technology

The working method is mostly intermittent batch mixing. Usually, a certain amount of multi-component materials to be mixed is placed in the mixing equipment, and the blades are stirred at a certain speed for a period of time, and then the mixed materials are discharged. Due to the particles and powder in the mixture The particle size, density, and fluidity of materials such as granules vary greatly, so it is difficult to achieve a uniform mixing effect, and it is easy to separate after mixing, during discharge, transportation, and use, which affects the stability of the product.

[0004] On the other hand, when these intermittent batch stirring devices are used, they are generally filled with materials with an effective volume of 40% to 60%. High-speed stirring is likely to cause temperature rise and damage the materials. During the mixing process, accumulation and agglomeration are pron
