Description

Technical Field

[0001] This utility model relates to the field of zirconium corundum abrasive screening technology, specifically a zirconium corundum abrasive weighing and screening device. Background Technology

[0002] Zirconia-corundum abrasive is an abrasive material made from alumina (Al2O3) and zirconium oxide (ZrO2) in an electric arc furnace at temperatures above 2000℃. Its main mineral phase is a eutectic formed by α-Al2O3 and Al2O3-ZrO2, with zircon as the secondary phase and a small amount of glassy phase. Its Mohs hardness is typically above 9.0, close to that of diamond, making it effective at grinding materials with high hardness, such as steel, ceramics, and glass. Screening is a crucial step in the production of zirconium-corundum abrasive. After crushing and shaping, the abrasive needs to be screened into products of different particle sizes to meet the requirements of various applications.

[0024] Example:

[0025] Please see Figure 1-4 This embodiment provides a zirconia-alumina abrasive weighing and screening device, including a base box 1. A screening frame 2 capable of sliding back and forth and a weighing mechanism 4 capable of weighing zirconia-alumina abrasives of different specifications after screening are respectively installed on the top of the base box 1. A sliding support plate 41 and a collection box 44 are installed on the weighing mechanism 4. The zirconia-alumina abrasive to be screened is poured onto the screening frame 2, and the screening frame 2 slides back and forth on the base box 1 to screen the zirconia-alumina abrasive. The zirconia-alumina abrasives of different specifications after screening by the screening frame 2 enter different collection boxes 44 for collection. After collection, each specification of zirconia-alumina abrasive is automatically weighed by the weighing mechanism 4. Thus, in the zirconia-alumina abrasive screening process, screening and weighing functions are integrated into one, and weighing is automatically completed after screening, eliminating the need for manual weighing and effectively improving the production and processing efficiency of zirconia-alumina abrasive.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a motor 15 is installed on the inner side of the base box 1, and a limit plate 16 is installed on the bottom inner side of the base box 1. One end of the rotating shaft of the motor 15 passes through the limit plate 16 and is fitted with an eccentric wheel 17. A pull rod 18 is rotatably connected to one side of the eccentric wheel 17. One end of the pull rod 18 is rotatably connected to the bottom of the screening frame 2. When the motor 15 rotates, the rotating shaft drives the eccentric wheel 17 to rotate. The rotation of the eccentric wheel 17 drives the pull rod 18 to pull the screening frame 2 to slide back and forth repeatedly inside the base box 1, thereby realizing vibration screening.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, three weighing devices 43 are installed vertically on one side of the support plate 41, and a collection box 44 is installed on the top of the weighing devices 43. The top of the weighing devices 43 has a protrusion that can be spliced ​​with the U-shaped groove at the bottom of the collection box 44. On the other side of the support plate 41, three display screens 42 are installed vertically, each corresponding to a weighing value of the three weighing devices 43. The three collection boxes 44 are located below each feeding hopper 21. After screening, the zirconium alumina abrasive can enter the corresponding collection box 44 through the corresponding feeding hopper 21 for collection. When the zirconium alumina abrasive enters the collection box 44, the weighing device 43 can weigh the zirconium alumina abrasive in the collection box 44 and display it on the display screen 42, thereby realizing automatic weighing after screening.

[0028] In this embodiment, as Figure 1 and Figure 4 As shown, two slide rails 12 are installed at one end of the top of the base box 1. A connecting plate 13 is fixedly connected between one end of the two slide rails 12. An electric push rod 14 is installed on the inner side of the connecting plate 13. The bottom of the support plate 41 is slidably installed on the slide rail 12. One end of the electric push rod 14 is connected to one side of the support plate 41. The electric push rod 14 is used to pull the support plate 41 to slide on the slide rail 12, so that the collection box 44 is pulled out from the bottom of the feed hopper 21. At this time, the collection box 44 can be directly removed to collect the zirconium corundum abrasive.

[0029] Working Principle: When using this zirconium alumina abrasive weighing and screening device, the zirconium alumina abrasive is first poured into the top inner side of the screening frame 2 through the feeding frame 3. When the motor 15 rotates, the rotating shaft drives the eccentric wheel 17 to rotate. The rotation of the eccentric wheel 17 drives the pull rod 18 to pull the screening frame 2 back and forth repeatedly inside the base box 1 to achieve vibration screening. After screening, the zirconium alumina abrasive can enter the corresponding collection box 44 through the corresponding feeding hopper 21 for collection. When the zirconium alumina abrasive enters the collection box 44, the weighing device 43 can weigh the zirconium alumina abrasive in the collection box 44 and display it on the display screen 42, thereby realizing automatic weighing after screening. The electric push rod 14 pulls the support plate 41 to slide on the slide rail 12, so that the collection box 44 is pulled out from the bottom of the feeding hopper 21. At this time, the collection box 44 can be directly removed to centrally store the zirconium alumina abrasive, thereby effectively improving the production and processing efficiency of zirconium alumina abrasive.

[0030] All technical features in this embodiment can be freely combined according to actual needs.
