Technical Field

[0001] The present invention relates to the technical field of comminution equipment, and specifically to an ultrasonic comminution equipment for corundum micropowder. Background Art

[0002] Corundum micropowder is an abrasive, mainly composed of alumina. According to different colors and raw materials, corundum micropowder can be divided into white corundum micropowder and brown corundum micropowder. The color of white corundum micropowder is white, with high hardness, good insulation and wear resistance, and is commonly used in ultra-precision grinding and polishing in the crystal and electronics industries, as well as in the production of high-grade refractory materials, etc. The color of brown corundum micropowder is light brownish-brown, with high hardness and strength, and has characteristics such as impact resistance, high temperature resistance, oxidation resistance, corrosion resistance, and low creep, and is commonly used in fields such as free grinding, polishing, sandblasting, etc., and can also be used in the manufacture of resin cutting discs, angle grinding discs and coated abrasives, etc. Due to the excellent high-temperature properties and mechanical strength of corundum and other properties, it has been widely applied to many industrial fields such as metallurgy, machinery, chemical industry, electronics, aviation and national defense. The shape of the original corundum is irregular, and it needs to be comminuted before use, and then reshaped according to the usage requirements. With the development needs of the industry, the requirements for the particle size of corundum comminution are getting higher and higher, especially for ultra-fine comminuted corundum micropowder, and its demand is also increasing greatly. This requires the use of ultrasonic comminution equipment for corundum micropowder to comminute corundum micropowder using ultrasonic technology.

[0017] First, in the ultrasonic pulverizing device for corundum micro powder, the stirrer makes the corundum material and the liquid medium in the ultrasonic generating barrel flow, and cooperates with the ultrasonic pulverizer in the liquid medium to generate periodic changes of high pressure and low pressure by ultrasonic vibration, generating cavitation phenomenon and forming a strong shock wave, so that the corundum micro powder particles are subjected to strong impact, shear and compression forces.

[0018] Second, in the ultrasonic pulverizing device for corundum micro powder, the driving part and the stirring and flow expanding part cooperate to stir the corundum micro powder particles and the liquid medium to flow. The liquid medium in the flowing state contacts the second diversion slope plate and the arc-shaped impact plate to guide the material to flow along the slope, so that the liquid medium and the corundum micro powder particles approach the transducer. Then, the ultrasonic generator and the transducer are used to generate periodic changes of high pressure and low pressure by ultrasonic vibration to form a shock wave to impact the corundum micro powder particles, accelerating the pulverization and refinement efficiency of the corundum micro powder. Moreover, the first diversion slope plate and the second diversion slope plate are distributed on the side of the energy output area of the transducer to assist in guiding the ultrasonic impact on the liquid medium, thereby improving the convergence of the liquid medium and the energy.

[0019] III. The ultrasonic comminution equipment for the corundum micropowder, through the cooperation of the servo motor and the rotating shaft, makes the connecting plate and the arc-shaped stirring plate rotate. With the arc-shaped setting of the arc-shaped stirring plate, it promotes the flow and tumbling of the corundum micropowder particles and the liquid medium in the reaction barrel and the bottom cavity barrel, increases the contact opportunities and comminution probability between particles, promotes the uniform distribution of the powder in the entire reaction cavity through stirring, and then, with the setting of the guide groove and the dredging groove, conducts the corundum micropowder particles and the liquid medium for guiding and drainage, improves the mass transfer efficiency between the medium and the powder, to ensure the comminution effect of the corundum micropowder particles.

[0020] IV. The ultrasonic comminution equipment for the corundum micropowder, through the rotation of the rotating shaft, drives the coupling shaft and the fixed rod to rotate, so that the material collecting folding plate rotates, thereby driving the flow of the corundum micropowder particles, avoiding the situation of lower-layer deposition. Then, the flow blocking groove and the flow dividing groove are used to conduct the subdivision and diversion of the corundum micropowder particles. With the blocking of the material collecting folding plate, the transducer at the lower part can apply an impact force to the corundum micropowder particles to accelerate the comminution efficiency of the corundum micropowder. In addition, the baffle plate and the inclined partition plate are used to block and limit the material, adjust the flow direction of the corundum micropowder, so as to force the corundum micropowder to approach the transducer, thereby improving the comminution particle size of the corundum micropowder particles.

With the arc-shaped setting of the arc-shaped stirring plate 522, it promotes the flow and tumbling of the corundum micropowder particles and the liquid medium in the reaction barrel 11 and the bottom cavity barrel 13, increasing the contact opportunity and comminution probability between particles. Ultrasonic waves are applied in the liquid medium by the ultrasonic generator 21 and the transducer 22. The ultrasonic vibration generates periodic changes in high pressure and low pressure, resulting in the formation, growth, and rapid collapse of tiny bubbles, releasing local energy and forming a strong shock wave, causing the corundum micropowder particles to be subjected to strong impact, shear, and compressive forces, thereby being comminuted. Stirring promotes the uniform distribution of the powder in the entire reaction cavity. Then, with the settings of the guide groove 523 and the dredging groove 525, the corundum micropowder particles and the liquid medium are guided and diffused, improving the mass transfer efficiency between the medium and the powder. The arc-shaped partition plate 524 blocks the flowing corundum micropowder particles guided by the arc-shaped stirring plate 522 and the guide groove 523, avoiding local accumulation and enabling all particles to have the opportunity to contact the ultrasonic energy, accelerating the comminution of the corundum micropowder particles. At the same time, when the liquid medium is in a flowing state, it contacts the second diversion slope plate 65 and the arc-shaped impact plate 64, guiding the material to flow and impact along the slope, bringing the liquid medium and the corundum micropowder particles closer to the transducer 22. The first diversion slope plate 63 and the second diversion slope plate 65 are distributed on the side of the energy output area of the transducer 22 to assist in guiding the ultrasonic impact on the liquid medium. Through the rotation of the rotating shaft 512, the coupling shaft 531 and the fixed rod 532 are driven to rotate, causing the material collecting folding plate 533 to rotate and driving the corundum micropowder particles to flow, avoiding the situation of lower layer deposition. The blocking groove 534 and the diversion groove 535 are used to subdivide and guide the corundum micropowder particles. With the blocking of the material collecting folding plate 533, the lower transducer 22 can apply an impact force to the corundum micropowder particles, accelerating the comminution efficiency of the corundum micropowder. The blocking and restriction of the material by the baffle plate 536 and the inclined partition plate 537 adjust the flow direction of the corundum micropowder, forcing the corundum micropowder to approach the transducer 22, improving the comminution particle size of the corundum micropowder particles. With the continuous application of the cavitation effect, the corundum micropowder particles are continuously refined and evenly distributed in the liquid medium, reaching the required particle size and distribution state. After the comminution is completed, the solenoid valve at the discharge pipe 4 is opened, and the corundum micropowder and the liquid medium are exported for subsequent processing.
