Description

Technical Field

[0001] This utility model belongs to the field of refractory materials technology, specifically relating to a novel multi-layer vibrating screening device for white fused alumina. Background Technology

[0002] White corundum is made from industrial alumina powder using modern and unique processing technology. Its main component, aluminum oxide, has a mass content of over 99%, and it also contains small amounts of iron oxide, silicon oxide, and other components. It is white in color and is produced by melting at a high temperature of over 2000 degrees Celsius in an electric arc furnace and then cooling. After being crushed, shaped, magnetically separated to remove iron, and sieved into various particle sizes, it has a dense texture and high hardness.

[0003] Common specifications for white fused alumina granules include 8-5mm, 5-3mm, 3-1mm, and 1-0mm. Granules of different specifications are screened through the following process: coarse screening → bucket elevator → semi-finished product silo → linear vibrating screen → finished product silo. Traditional screening processes require numerous pieces of equipment, making the entire process difficult to plan and costly. Furthermore, linear vibrating screens, mainly composed of screens and wooden frames, are time-consuming to replace, resulting in low production efficiency and high costs. For example, a screening line capable of producing 20 tons of granules per hour requires one coarse screen, four fine screens, two bucket elevators, and other equipment, resulting in low capacity. Summary of the Invention

[0020] Combined with appendix Figure 1 and 2This invention details a novel multi-layer vibrating screening device for white fused alumina, comprising a screening box 5 with a sealed cavity structure. A storage box 3 is positioned above the screening box 5, with its outlet connected to the cavity of the screening box 5. The four corners of the bottom of the screening box 5 are elastically connected to vertically mounted support columns on a base 8 via spring damping devices 6. The base 8 is fixed to a support seat. The spring damping devices 6 provide shock absorption, preventing the vibration of the vibrating motor 7 from being transmitted through the screening box 5 to the support columns, base 8, and support seat during the feeding of white fused alumina particles, thus avoiding metal fatigue and improving the overall strength of the multi-layer vibrating screening device. Several finished product bins 10 are positioned below the support seat. The bottom of the support seat is fixedly connected to a base via several vertically mounted square steel supports 9. The base is directly or indirectly fixed to the ground. Vibrating motors 7 are positioned on both sides of the bottom of the screening box 5. The vibration is adjusted... The vibration frequency and amplitude of the motor 7 control the feeding speed of the white fused alumina particles. The particles fall within the screening box 5, preventing blockages during feeding. Several inclined screens 14 are spaced vertically within the screening box 5, with the screen openings decreasing in size from top to bottom. The screens 14 are detachably connected to the inner wall of the screening box 5. Finished product outlets 15 are located above the front end of the screening box 5, corresponding to the positions of the screens 14. The corresponding chute 16 is connected to the corresponding finished product silo 10. A dust removal pipe 4 is set above the screening box 5. One end of the dust removal pipe 4 is connected to the cavity of the screening box 5, and the other end of the dust removal pipe 4 is connected to the air inlet pipe of the dust collector 1. The dust collector 1 is an existing device. The dust collector 1 is set on the base by a bracket. The dust collector 1 is used to collect the dust generated during the screening of white fused alumina granules in the screening box 5, so as to ensure that no dust overflows from the screening box during the screening of white fused alumina granules.

[0021] like Figure 2As shown, preferably, five inclined screens 14 are arranged vertically at intervals within the screening box 5, corresponding to six finished product bins 10: the first finished product bin 10.1, the second finished product bin 10.2, the third finished product bin 10.3, the fourth finished product bin 10.4, the fifth finished product bin 10.5, and the sixth finished product bin 10.6. Particles with a diameter >15mm on the uppermost screen 14 enter the first finished product bin 10.1 through the corresponding finished product outlet 15; particles with a diameter less than or equal to 15mm and greater than 8mm on the second screen 14 enter the second finished product bin 10.6 through the corresponding finished product outlet 15. 10.2; The particles on the third screen with a diameter of less than or equal to 8 mm and greater than 5 mm enter the third finished product bin 10.3 through the corresponding finished product outlet 15; The particles on the fourth screen with a diameter of less than or equal to 5 mm and greater than 3 mm enter the fourth finished product bin 10.4 through the corresponding finished product outlet 15; The particles on the fifth screen with a diameter of less than or equal to 3 mm and greater than 1 mm enter the fifth finished product bin 10.5 through the corresponding finished product outlet 15; The particles under the fifth screen with a diameter of less than or equal to 1 mm enter the sixth finished product bin 10.6 through the corresponding finished product outlet 15.

[0022] This utility model of a multi-layer vibrating screen for white fused alumina replaces the traditional screening process that requires multiple coarse and fine screens. It occupies less space, has a simpler layout, and offers higher screening efficiency. The number of screens can be increased to produce various products with different particle sizes. Simultaneously, the screens are evenly distributed, easy to replace, and highly automated, reducing labor intensity and costs while improving production efficiency. For example, to produce finished 8-5mm, 5-3mm, 3-1mm, and 1-0mm particles, only four layers of screens (8.3mm, 5.3mm, 3.3mm, and 1.3mm) need to be installed from top to bottom. 20-0mm particles can be screened using this new multi-layer vibrating screen for white fused alumina, achieving high screening efficiency and producing over 50 tons of finished white fused alumina per hour.

[0023] As an optional design, the novel white corundum multi-layer vibrating screening device preferably has several steel pipes 12 spaced apart below each screen 14 along the inclined direction of the screen 14. The steel pipes 12 are used to support the screen 14, and the two ends of the steel pipes 12 are fixedly connected to the inner wall of the screening box 5 to improve the strength of the screen 14 and ensure that the screen can withstand a large weight.

[0024] As an optional design, the novel white corundum multi-layer vibrating screening device is preferably provided with a screen box side plate 2 detachably connected to the rear end of the screening box 5. The front end of the screen 14 is hung on the hanging plate on the inner wall of the screening box 5 by a hook. The rear end of the screen 14 is elastically connected to the screen box side plate 2 through an elastic element, which facilitates the disassembly of the screen 14.

[0025] As an optional design, the novel white corundum multi-layer vibrating screening device is preferably equipped with several lightweight cover plates 11 detachably connected to the top of the screening box 5. The screening box 5 can be opened through the lightweight cover plates 11 to facilitate the maintenance of the steel pipes and screens inside the screening box.

[0026] As an optional design, the novel white corundum multi-layer vibrating screening device is preferably provided with a number of observation holes 13 at intervals on both sides of the screening box 5 corresponding to the screen 14. The screening of the granular material on the corresponding screen 14 can be observed through the observation holes 13. A sealing cap is detachably connected to the observation hole 13.

[0027] The working process of this utility model is as follows:

[0028] During operation, dust collector 1 is turned on first to ensure that no dust overflows from the granular material in the screening box 5 during the screening process. The white corundum granules in the storage box 3 are dispersed and continuously jump forward under the action of the vibration motor and their own gravity. The screen 14 in the screening box 5 classifies the material. Large particles are intercepted and discharged from the top finished product outlet. Smaller particles of different sizes enter the lower layer, and so on, and are discharged from their respective finished product outlets. During this process, the screening situation of the granular material can be well observed through the observation hole 13, and the amplitude of the vibration motor 7 can be adjusted in time to ensure that the screening particle size is qualified. The screened granules enter the corresponding finished product bin through the corresponding chute. The screening work is completed. This new utility model of corundum multi-layer vibrating screening device has a small footprint, easy process layout, high screening efficiency, and can increase the number of screens to produce a variety of products with different particle sizes.

[0029] The above description is only an application implementation of this utility model, but the protection scope of this utility model is not limited thereto and cannot be used to limit the scope of rights of this utility model. Any equivalent changes made according to the technical solution of this utility model should be included within the protection scope of this utility model.
