Description

Technical Field

[0001] The present invention relates to the technical field of material mixing, and specifically to a high-precision depolymerization, shearing and dispersion mixing device. Background Art

[0002] Material mixing is an operation process of uniformly mixing two or more different materials together, which is widely used in many industries such as chemical industry, food, pharmaceutical, and construction. In production, it is often necessary to mix various materials with different components to ensure that the composition and properties of each part of the final product are consistent. For example, in food processing, various seasonings, additives are mixed with the main ingredients to make the taste and quality of the food stable. By mixing materials with different properties, a mixture with new or better properties can be obtained. For instance, in plastic production, different polymers or additives are mixed to improve the properties such as strength, toughness, and heat resistance of the plastic.

[0003] Currently, the existing material mixing devices have the following disadvantages: 1. In conventional equipment, there are two mechanisms of stirring and shearing installed at the upper end of the reaction kettle, resulting in a large dead angle in the bottom area of the reaction kettle. When feeding materials, large pieces and large particles of materials will directly sink to the bottom of the reaction kettle, and the upper stirring and shearing mechanisms cannot have a good treatment effect on the materials below, resulting in unevenness of the whole batch of materials. When transferring to the next process, first, the large pieces of materials at the bottom will block the discharge pipeline, leading to the disassembly and cleaning of the pipeline, which not only causes material leakage but also increases the labor input. Second, the uneven materials will affect the treatment effect during the next process and increase the processing time of the next process.

[0004] 2. Since the two mechanisms of stirring and shearing are installed at the upper end of the reaction kettle, the main drive shafts of stirring and shearing will be very long. The longer the shaft, the worse the jumping and precision, and the faster the bottom parts of stirring and shearing will be worn and damaged, greatly reducing the service life of the equipment and indirectly increasing the use and maintenance costs. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-precision depolymerization, shearing and dispersion mixing device to solve the problems raised in the above background art.

A liquid inlet 22 is fixedly connected to the top of the kettle cover plate 21. A feeding port 23 is fixedly connected to the top of the kettle cover plate 21. Through the redesigned feeding port 23, when feeding materials, large pieces and large particles of materials directly fall from the material inlet onto the crushing knives 26, and the large pieces of materials will be directly broken. Passing through the lower shear rotor 28, along with the thrust at the bottom of the rotor, it moves upward along the kettle wall, and finally forms a circulating flow in the area flowing into the crushing knives 26, ensuring uniform shearing of the materials, and solving the problems of material precipitation and poor shearing and mixing effect caused by large pieces and large particles of materials directly sinking to the bottom during feeding; moreover, the transmission components are short in length, good in stability, high in precision and long in service life, reducing the use and maintenance costs; at the same time, it solves the problem of blockage of the discharge pipeline caused by precipitation, avoids material waste and reduces labor input; due to the bottom design, it is convenient for maintenance and also reduces space occupation; conventionally, stirring and shearing are installed at the upper end of the reaction kettle, which requires two motors 203 for transmission.
