Description

Technical Field

[0001] This utility model relates to the field of extrusion granulation technology, and in particular to a nanomaterial compression granulation device. Background Technology

[0002] With the rapid development of new materials technology, nanomaterials, with their unique physicochemical properties such as high specific surface area and quantum size effect, have shown enormous application potential in fields such as electronics, biomedicine, and aerospace. The granulation process of nanomaterials, as a key link between raw material preparation and downstream applications, directly affects the molding quality, dispersibility, and performance of the material. However, current nanomaterial compression granulation equipment on the market generally suffers from numerous technical bottlenecks, making it difficult to meet the industry's growing demand for high-quality and high-efficiency production.

[0003] On the one hand, traditional nanomaterial granulation equipment is inefficient during the material polymerization stage. Most equipment lacks effective means to promote material agglomeration, relying only on simple mechanical stirring, which cannot fully utilize the surface activity of nanomaterials to achieve rapid polymerization. For nanoparticles that are extremely prone to agglomeration, traditional equipment has difficulty controlling the degree and uniformity of agglomeration, resulting in some nanomaterials not being fully combined before granulation, affecting subsequent extrusion molding and particle quality, causing material waste and unstable performance.

[0004] On the other hand, the extrusion molding process of existing equipment has defects. The single-extrusion mode makes it difficult to precisely control the material density and shape, failing to meet the diverse needs of different application scenarios for nanomaterial particle size and strength. Furthermore, uneven stress on the material during extrusion can easily lead to problems such as rough particle surfaces and high internal porosity, reducing the physical properties and processing adaptability of nanomaterials. Simultaneously, the equipment lacks continuous production capacity, and the connection between material conveying and the extrusion process is not smooth, resulting in low production efficiency and difficulty in adapting to the pace of large-scale industrial production.

[0005] In summary, the development of a nanomaterial compression granulation device capable of achieving efficient polymerization and precise extrusion has become an urgent need to promote the industrialization of nanomaterials and improve material performance and production efficiency. The nanomaterial compression granulation device of this invention was developed in response to this need. Utility Model Content

[0012] A granulation mechanism is provided at the end of the extrusion cylinder and is used to granulate the material extruded from the extrusion cylinder.

[0013] As a further embodiment of this utility model: the first driving mechanism includes a drive motor and a reducer fixedly mounted on the upright frame. The driving end of the drive motor is connected to the input end of the reducer via a transmission belt. The output end of the reducer is rotatably connected to a first gear.

[0014] As a further embodiment of this utility model: the transmission assembly includes a second gear fixedly installed at one end of the rotating shaft, the first gear and the second gear are connected by a first chain transmission, a third gear is fixedly installed at one end of the first auger rod, and a fourth gear is also fixedly installed on the outer wall of the rotating shaft, and the fourth gear and the third gear are connected by a second chain transmission.

[0015] As a further embodiment of this utility model: the second drive mechanism includes a servo motor fixedly mounted on the upper surface of the base, and a transmission wheel is rotatably mounted on the upper surface of the base. The output end of the servo motor and the transmission wheel are connected by a first track drive.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention provides a nanomaterial compression granulation device that achieves rapid polymerization of nanomaterials through the synergistic action of a spray mechanism and a stirring structure. Sprayed water in the feeding hopper promotes the adsorption and agglomeration of nanomaterials, while a first drive mechanism drives the rotating shaft and stirring rod to rotate at high speed, enhancing material mixing and collision, and significantly improving the polymerization rate. This design allows for precise control of the agglomeration degree, ensuring that the nanomaterials have a good binding state before entering subsequent processes, laying the foundation for high-quality granulation.

[0021] The first auger rod plays a crucial role in the initial extrusion process. Driven by the first drive mechanism, the rotating first auger rod pushes the polymerized nanomaterials to the end of the auger cylinder for extrusion. Through helical propulsion and constraint by the cylinder wall, the material is initially shaped and densified. This process effectively removes air from the material, adjusts its density, and forms a uniform preform suitable for secondary extrusion, reducing the risk of deformation during subsequent processing.

[0022] The secondary extrusion system, consisting of a second drive mechanism and an extrusion cylinder, further optimizes the molding quality of nanomaterials. The second auger rotates within the extrusion cylinder, precisely controlling the extrusion pressure and propulsion speed to deeply compact and finely shape the material. Secondary extrusion allows for flexible adjustment of extrusion parameters based on different material properties and product requirements, ensuring that particle density, strength, and shape meet standards, thereby improving the consistency and stability of the finished nanomaterial product.

[0023] The equipment's granulation mechanism enables the efficient conversion of materials from strips to granules. After secondary extrusion, the material is rapidly formed into regular granules through cutting, shaping, and other processes by the granulation mechanism. This mechanism can flexibly adjust the particle size and shape according to actual production needs, adapting to applications in multiple fields such as electronics and pharmaceuticals, while ensuring a continuous and stable granulation process, significantly improving the production efficiency and finished product qualification rate of nanomaterials.
