Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding media screening technology, specifically a grinding bead vibrating screening device. Background Technology
[0002] In industries such as mining, building materials, coatings, ceramics, metallurgy, and chemicals, grinding equipment such as ball mills, stirred mills, and vibratory mills are core equipment for material crushing and ultrafine grinding. Grinding media (usually spherical or near-spherical grinding beads), as consumable components in these devices, will shrink in size or even break after prolonged use due to wear, leading to decreased grinding efficiency and potentially contaminating the purity of the final product. Therefore, regularly screening the used grinding media to remove broken beads and excessively small worn beads, and replenishing with new beads, is a crucial step in maintaining the stable and efficient operation of the grinding system.
[0003] Currently, mechanical vibration screening is commonly used to screen grinding media. This involves pouring used grinding media (grind beads) onto the vibrating screen surface to separate broken beads and excessively small wear beads from qualified grinding beads.
[0004] However, in practical applications, this method has obvious drawbacks: on the one hand, traditional vibrating screen equipment is mostly open structure, which easily generates a lot of dust during feeding and screening, which not only pollutes the working environment but also poses a threat to the health of workers; on the other hand, due to the shape and motion characteristics of the grinding beads, they are very easy to get stuck in the screen holes during screening, causing screen blockage. Once blocked, the machine must be stopped and manually knocked to clean it, which is cumbersome and seriously affects screening efficiency and production continuity.
[0005] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0006] This utility model provides a vibrating sieving device for grinding beads. By setting a dustproof plate, the top of the sieving box can be sealed. By setting a negative pressure pipe and a dust collection bag, the dust generated in the sieving box during feeding and sieving can be cleaned and collected. By setting an elastic whip, the screen plate can be efficiently unblocked. This solves the problems mentioned in the background art, such as the dust hazard easily generated in the existing grinding bead sieving process, and the screen being difficult to unblock, which affects the sieving efficiency and continuity.
[0007] This utility model provides the following technical solution:
[0008] A vibrating sieving device for grinding beads includes a sieving box with a screen plate fixedly installed inside. Both sides of the sieving box are fixedly connected to discharge pipes.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] Reference Figures 1-4A vibrating sieving device for grinding beads includes a sieving box 1 with a screen plate 2 fixedly installed inside. Discharge pipes 3 are fixedly connected to both sides of the sieving box 1, one discharge pipe 3 located at the top surface of the screen plate 2 and the other discharge pipe 3 located at the bottom of the sieving box 1. A vibrating element is installed at the bottom of the sieving box 1 for sieving the added grinding beads. The device also includes a dustproof plate 5 detachably and fixedly connected to the top of the sieving box 1, the dustproof plate 5 being bolted to the top of the sieving box 1. A feeding element is installed on the dustproof plate 5 for adding grinding beads into the sieving box 1. A negative pressure pipe 6 is fixedly connected to the sieving box 1, and the negative pressure... One end of the pipe 6 extends into the screening box 1. A dust removal section is provided on one side of the screening box 1. The dust removal section is used to generate negative pressure suction in the negative pressure pipe 6 to clean up dust and prevent dust from overflowing and thus harming the environment and workers' health. Multiple sets of elastic whips 7 are all set at the bottom of the screening box 1. The multiple sets of elastic whips 7 are arranged at equal intervals along the length of the screen plate 2. The number of elastic whips 7 is 8-18 sets. In this device, 12 sets are preferred. The elastic whips 7 are made of wear-resistant fiber fabric and rubber composite. The screening box 1 is provided with a driving part. The driving part is used to drive the elastic whips 7 to strike the bottom surface of the screen plate 2, thereby efficiently clearing the screen plate 2.
[0029] Of course, in other embodiments, the dust removal unit includes a vacuum cleaner 61 fixedly installed on the outer wall of the screening box 1. The air inlet of the vacuum cleaner 61 is connected to the negative pressure pipe 6 through the suction pipe 62, and the exhaust end of the vacuum cleaner 61 is fixedly connected to the air supply pipe 63. The end of the air supply pipe 63 away from the vacuum cleaner 61 is fixedly fitted with a dust removal bag 64 through an elastic band. The elastic band enables quick assembly and disassembly of the dust removal bag 64. A support plate 9 is fixedly connected to one side of the outer wall of the screening box 1. The dust removal bag 64 contacts the supporting surface of the support plate 9, which can improve the stability of the dust removal bag 64 and prevent it from falling due to excessive weight.
[0030] Specifically, during use, by activating the vacuum cleaner 61, negative pressure suction is generated in the negative pressure pipe 6, which draws the dust generated during the feeding and screening process in the screening box 1 into the continuous negative pressure pipe 6, and then discharges it into the dust collector bag 64 through the suction pipe 62 and the air delivery pipe 63 for centralized collection, thereby cleaning up the dust and preventing dust from overflowing and thus harming the environment and workers' health.
[0031] The drive unit includes a geared motor 81 fixedly mounted on the outer wall of the screening box 1. The model can be Flander Primo series or Bonfiglioli 700 / 800 series. At least two rotating rods 8 are rotatably connected inside the screening box 1. An elastic whip 7 is fixedly connected to the rotating rod 8. One end of the rotating rod 8 extends outside the screening box 1. The output end of the geared motor 81 and the end of the rotating rod 8 extending outside the screening box 1 are both fixedly connected to meshing gears 82. A housing 10 is fixedly connected to the outer wall of the screening box 1. The geared motor 81 and the gears 82 are both located inside the housing 10, which is used to shield and protect the geared motor 81 and the gears 82, and also improves the aesthetics of the device.
[0032] Specifically, during use, by starting the reduction motor 81, the gear 82 and the rotating rod 8 are driven to rotate, which in turn drives multiple sets of elastic whips 7 to rotate and strike the bottom surface of the screen plate 2 in the opposite direction. Then, by utilizing the gravity of the grinding beads themselves and the impact force of the screen surface undulating upward, the grinding beads stuck in the screen holes can be pushed out and bounced along the screen plate 2 to the discharge pipe 3 for discharge, so as to achieve efficient unblocking of the screen plate 2, thereby helping to improve screening efficiency and production continuity.
[0033] The feeding component includes a bracket 51 fixedly connected to the top of the dustproof plate 5. A hopper 52 is fixedly installed on the bracket 51. The discharge end of the hopper 52 passes through the dustproof plate 5 and extends into the screening box 1. A hopper cover 53 is snapped onto the top of the hopper 52.
[0034] Specifically, in use, the grinding beads to be screened are poured into the hopper 52. The grinding beads enter the screening box 1 through the discharge end of the hopper 52 and fall onto the screen plate 2 for feeding. The hopper cover 53 can cover the top opening of the hopper 52 and play a protective role.
[0035] The vibrating component includes a base 4 located below the screening box 1. Multiple springs 41 are fixedly installed between the top of the base 4 and the bottom of the screening box 1. The number of springs 41 is 6-12. This device preferably uses 8 springs as an example. A vibrating motor is fixedly installed at the bottom of the screening box 1. The model of the vibrating motor can be Yongmei Machinery YZU series or Shangzhen YZO series.
[0036] Specifically, during use, by starting the vibration motor and with the cooperation of the spring 41, the screening box 1 and the screen plate 2 generate high-frequency, small-amplitude periodic vibration. The vibration force can be used to screen the added grinding beads. Qualified grinding beads will be intercepted by the screen plate 2 and discharged through the discharge pipe 3 under the action of vibration force, while broken beads and unqualified wear beads that are too small will pass through the screen plate 2 and fall into the bottom of the screening box 1, and be discharged along the inclined surface through another discharge pipe 3.
