Description

Material distribution device and method Technical field

The invention relates to the technical field of batching, in particular, to a material distribution device and method.

Background technique

Material mixing is an indispensable part of manufacturing in many industries, such as modified plastics industry, food processing industry and chemical products. The uniformity of the material mixing directly determines the quality and stability of the product, and the production raw materials often have multiple components and their respective ratios, shapes and particle sizes are different, so it is not easy to mix evenly when mixing. If it is manually mixed, the workload is large, the labor intensity of the operator is large, and the effect of material mixing is not ideal.

At present, the mixing equipment is mainly a variety of mixing equipment, commonly used are: high-speed mixer, low mixer, horizontal mixer, double spiral cone mixer, non-gravity mixer and other mechanical stirring devices. The mixing method is to drive the mixing paddle through the mixing shaft to force the materials to be mixed. The mixing methods include single-axis, multi-axis, vertical, horizontal, spiral, spiral belt, rotation, rotation + revolution and so on. The working mode is mostly batch batch mixing, usually a certain amount of multi-component materials to be mixed are placed in the mixing equipment, 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 the materials are very different, it is difficult to achieve a uniform mixing effect, and it is easy to delaminate after mixing, discharging, conveying, and using, which affects the stability of the product.

On the other hand, these intermittent batch mixers are generally filled with materials with an effective volume of 40% to 60%. High-speed stirring is likely to cause heating and damage to the materials. During the mixing process, it is easy to accumulate and agglomerate. On the bottom of the barrel, an obvious dead angle is formed, which affects the uniformity of the mixture. According to the actual production situation, the existing mixing equipment often has insufficient mixing in a short time due to the single mixing structure. Long-term mixing affects the subsequent processing process and will cause the material to heat up seriously and affect the product quality.

In addition, the mixing equipment has high equipment investment costs, high power consumption, and difficult equipment maintenance. When a failure occurs, the on-site operators cannot fully repair and affect production, and there is a greater operational safety risk. Due to the complex structure, There are also problems such as inconvenience and time-consuming transfer of cleaning machines.

As a first preferred implementation of the torque difference, the flow rate of the first material conveyed by the first feeding device is smaller than the flow rate of the second material conveyed by the second feeding device. Since the flow rate of the first material conveyed by the first feeding device is less than the flow rate of the second material conveyed by the second feeding device, even if the two materials contact the rotating blade 409 at the same speed, the difference in mass makes the first The impact force of the strand material on the rotating blade 409 is less than the impact force of the second strand material on the rotating blade 409, thereby generating a torque difference.

As a second preferred way of realizing the torque difference, the first feed channel is closer to the center of the rotating shaft 4091 of the rotating blade 409 than the second feed channel.

Due to the difference in speed between the two, even if other conditions remain unchanged, there can be a moment difference between the moment the first material acts on the rotating blade 409 and the moment the second material acts on the rotating blade 409.

In this embodiment, the above first, second, and third preferred torque difference realization structures may be used separately, or two or three of them may be combined together. When the three are combined, the flow of the first material conveyed by the first feeding device is less than the flow of the second material conveyed by the second feeding device, and the first feed channel is closer to the rotating paddle than the second feed channel The height of the center of the rotating shaft 4091 of the blade 409 and the inlet of the first feed stand 5 is smaller than the height of the inlet of the second feed stand 6, which can significantly increase the torque difference and at the same time can make the outside of the barrel 401 And the internal structure remains simple and compact.

The working principle of the material distribution device in this embodiment is that the first feeding device is activated to convey the first material from the first feed channel into the barrel 401, and the second feed device is activated from the second feed channel to the barrel 401 The second material is transported internally, so that there is a torque difference between the moment the first material acts on the rotating blade 409 and the moment the second material acts on the rotating blade 409.

The material distribution device according to claim 20, wherein the planar blades are configured to form a regular polygon with one side extended, the blades are sealed on both sides, and the extended sides of the regular polygon are in the form of clockwise or counterclockwise Arranged, the adjacent two sides form a "√" type structure and have a preset volume. The material distribution device according to claim 20, wherein the curved blades are combined into a polygon, the blades are sealed on both sides, and the concave structure of the blades has a predetermined volume. The material distribution device according to claim 20, characterized in that the "S"-like blades are evenly distributed on the rotating shaft along the circumference, and the "S"-like blades are bent by themselves to form a concave The groove, the groove has a preset volume, and is respectively on both sides of the center plane of the blade. A material distribution method, characterized in that the material distribution device according to any one of claims 1-23 is used to perform the following operations: Start the first feeding device to deliver the first strand of material from the first feed channel to the barrel, and start the second feeding device to deliver the second strand from the second feed channel to the barrel Materials, so that there is a torque difference between the moment of the first material acting on the rotating blade and the moment of the second material acting on the rotating blade, the torque difference is used to drive the rotating blade The blade rotates to drive the material on the rotating blade to rotate to a preset angle and then start to fall. During the falling process, the two materials collide, the material and the rotating blade, and the material and the cylinder wall to achieve uniformity. mixing. The material distribution method according to claim 24, wherein when the rotation speed of the rotating blade is lower than a preset value, a dynamic driving device is provided to drive the rotating blade to rotate.
