Description

Technical Field

[0001] This utility model belongs to the field of grinding equipment technology, and specifically relates to a high-efficiency nano-grinding equipment. Background Technology

[0002] In the field of grinding equipment, traditional disc-type dispersion devices have many shortcomings. For example, their grinding efficiency is low, making it difficult to grind materials to a uniform nanoscale particle size in a short time. This deficiency is extremely detrimental to the production of products with extremely high particle size requirements, such as nano-pigment pastes, seriously affecting production efficiency and product quality. Secondly, ordinary equipment performs poorly in preventing metal ion contamination of materials. The mixing of metal ions into the material affects product quality, which is a significant issue for materials with high purity requirements. Furthermore, existing grinding equipment also has deficiencies in heat dissipation, sealing, and adaptability to different material characteristics. In the grinding process of water-based materials, due to the special physicochemical properties of these materials, ordinary equipment struggles to achieve ideal grinding results, easily leading to problems such as agglomeration and uneven dispersion, failing to meet the ever-increasing demands for high-quality production. These problems pose significant challenges to traditional grinding equipment in modern production, urgently requiring technological improvements and innovations to adapt to evolving production needs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency nano-grinding device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: a high-efficiency nano-grinding device, including a turbine grinding system, a material conveying component, a sealing and cooling component, a control and monitoring component, and an air supply component; the turbine grinding system includes a turbine and a grinding chamber, the turbine being axially disposed within the grinding chamber; the material conveying component includes an inlet and an outlet; the sealing and cooling component includes a mechanical seal cooling tank and a cooling water circuit, the mechanical seal cooling tank being disposed near the grinding chamber, and the outer wall of the grinding chamber being wound with a spirally guided cooling water circuit; the air supply component includes an air source processor, the air source processor being disposed below the grinding chamber.

[0005] In a preferred embodiment of the present invention, the turbine includes a rotating shaft and blades.

[0006] In a preferred embodiment of this utility model, the turbine is made of zirconium oxide and the grinding chamber is made of silicon carbide.

[0007] In a preferred embodiment of this utility model, the grinding medium in the grinding chamber is one or more of yttrium zirconium beads, cerium zirconium beads, composite zirconium beads, zirconium silicate beads, and silicon nitride zirconium beads. The appropriate size of zirconium beads is selected according to the material characteristics to achieve the best grinding effect.

[0008] In a preferred embodiment of this utility model, the control and monitoring component includes a PLC control panel.

[0009] In a preferred embodiment of this utility model, the cooling water circuit is equipped with a cooling water temperature gauge.

[0010] The material to be ground enters the grinding chamber through the feed inlet. The turbine, installed inside the grinding chamber, has blades that directly contact the grinding media and the material. During operation, the turbine rotates at high speed, mixing the material with the grinding media to achieve the grinding function. After grinding is complete, the material is discharged from the discharge outlet.

[0011] The mechanical seal cooling tank provides cooling for the sealing device, preventing damage due to frictional heat. A cooling water temperature gauge is installed in the cooling water circuit to monitor the cooling water temperature in real time, allowing operators to easily monitor the cooling status. A spiral-guided cooling circuit is wound around the outer wall of the grinding chamber. Through a special spiral design, the cooling water flows in the circuit, carrying away the heat generated in the grinding chamber and improving cooling efficiency. The PLC control panel displays the equipment's operating parameters, allows for the setting and adjustment of various parameters of the sand mill, and enables real-time monitoring of the equipment's operating status.

[0012] Compared with the prior art, this technical solution has the following advantages:

[0013] This invention employs a higher-standard turbine rotor that rotates within the cavity to form a vortex. The grinding media rotates under the influence of the vortex, continuously shearing and dispersing large particles of the grinding material. The large amplitude and diverse motion patterns of the media within the cavity result in a higher particle capture rate. The designed turbine accelerator and more wear-resistant materials better meet more stringent product requirements, achieving high efficiency, low energy consumption, and reduced pollution.
