Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mineral screening equipment, and in particular to a screening device for aluminum ore processing. Background Technology
[0002] A common step in ore processing is screening the ore to obtain ores of different particle sizes for separate processing. The most commonly used equipment in this process is the vibrating screen, which typically includes a screen box, screen mesh, vibrating motor, and spring mechanism. The vibrating motor causes the screen to vibrate vertically. Because the screen mesh is inclined, the ore vibrates vertically as it moves downwards, causing smaller particles to pass through the upper screen and fall, while larger particles continue to move forward on the screen.
[0003] Because of the varying particle sizes of the ore, dust carried by the ore itself or generated during the screening process will be scattered in all directions, polluting the air and the surrounding environment. This dust phenomenon is a key issue in air pollution control. Therefore, existing technologies include spray dust suppression. Although this process has good performance, it consumes water resources continuously, and the spray combined with dust adheres to the factory ground or other equipment, making it difficult to clean. Utility Model Content

[0013] By adopting the above technical solution, the use of corrugated hoses facilitates the sealing connection between the upper and lower main pipes and the dynamic height adjustment of the upper main pipe.
[0014] Optionally, the corrugated hose is fitted with a protective sleeve to protect the corrugated hose.
[0015] By adopting the above technical solution, the protective sleeve can effectively protect the corrugated hose from the impact of dust particles and extend the service life of the corrugated hose.

[0018] Optionally, a lower support rod is fixed to the outer wall of the lower main pipe, and a lower ring plate fitted onto the lower main pipe is fixed to the end of the lower support rod. An upper support rod is fixed to the outer wall of the upper main pipe, and an upper ring plate fitted onto the upper main pipe is fixed to the end of the upper support rod. A protective sleeve is fitted onto the outer side of the upper and lower ring plates. The bottom of the protective sleeve is connected to the lower ring plate by screws.

The screen box 10 is also equipped with a vibrating motor and a spring mechanism (not shown in the figure). The bracket 2 is bolted to the screen box 10, and a spring washer or other structure can be installed at the connection. The dust collection mechanism 3 includes a dust collection main pipe 30, a dust collection branch pipe 31, a dust collection hood 32, a dust discharge pipe 33, and a bag dust collector (not shown in the figure). The dust collection main pipe 30 includes an upper main pipe 300 and a lower main pipe 301. The upper main pipe 300 is L-shaped, and the two upper main pipes 300 are connected by a flange, with the connection point located directly above the screen 11. The two upper main pipes 300 form a portal frame structure that spans the screen 11.
[0031] Reference Figure 1 and Figure 2 The lower main pipe 301 is vertically fixed to the end of the support 2 and extends downward. The dust suction branch pipe 31 is set along the length of the screen box 10. Part of the dust suction branch pipe 31 is fixed to the upper main pipe 300 and located directly above the screen 11. The other part of the dust suction branch pipe 31 is fixed to the bottom of the lower main pipe 301 and located to the side of the bottom of the screen box 10. Several dust suction holes are opened on the dust suction branch pipe 31. The dust suction hood 32 is fixed to the dust suction branch pipe 31 and faces the vibrating screen body 1. Dust is absorbed through the dust suction hood 32. The dust discharge pipe 33 is connected to the lower main pipe 301 and the bag dust collector is connected to the dust discharge pipe 33.
[0032] Reference Figure 2 and Figure 3 The height adjustment mechanism 4 is located between the upper main pipe 300 and the lower main pipe 301. The height adjustment mechanism 4 includes a corrugated hose 40 connected between the upper main pipe 300 and the lower main pipe 301. The end of the corrugated hose 40 is fixed by a clamp 41. Multiple lower support rods 42 are uniformly fixed to the periphery of the lower main pipe 301. The ends of the multiple lower support rods 42 are fixed to a lower ring plate 43 sleeved on the lower main pipe 301. Multiple upper support rods 44 are uniformly fixed to the periphery of the upper main pipe 300. The ends of the multiple upper support rods 44 are fixed to an upper ring plate 45 sleeved on the upper main pipe 300. The outer diameter of the upper ring plate 45 is the same as that of the lower ring plate 43.
[0033] Reference Figure 3 A protective sleeve 46 is fitted on the outer side of the lower ring plate 43 and the upper ring plate 45. The bottom of the protective sleeve 46 is fixed to the lower ring plate 43 by screws. Two sliding grooves 460 are vertically opened on the periphery of the protective sleeve 46. A connecting screw 47 is threadedly connected to the upper ring plate 45 through the sliding groove 460. An adjusting screw 48 is vertically arranged below the connecting screw 47. An installation ring 480 is fixed to the top of the adjusting screw 48 and is fitted on the connecting screw 47.
[0034] Reference Figure 3A limiting tube 481 is fixedly connected to the side of the mounting ring 480 near the protective sleeve 46. The limiting tube 481 is sleeved on the connecting screw 47 and abuts against the protective sleeve 46. A baffle 49 is vertically fixed to the outer wall of the protective sleeve 46 at a position directly below the connecting screw 47. The bottom of the adjusting screw 48 slides through the baffle 49. An adjusting nut 482 for fixing the position of the adjusting screw 48 is threaded on the adjusting screw 48 and abuts against the baffle 49.
[0035] The implementation principle of the screening device for aluminum ore processing in this embodiment of the utility model is as follows: During the screening of aluminum ore by the vibrating screen body 1, the bag dust collector of the dust collection mechanism 3 generates negative pressure, so that the dust passes through the dust collection hood 32, the dust collection branch pipe 31, the dust collection main pipe 30 and the dust discharge pipe 33 in sequence and enters the bag dust collector, thereby effectively removing dust from the top of the screen 11 and the bottom of the screen box 10.
[0036] The height of the dust collection hood 32 located above the screen 11 can be adjusted according to the thickness of the ore layer, vibration frequency, and adsorption range. The upper main pipe 300 and the lower main pipe 301 are connected by a corrugated hose 40 to facilitate dynamic adjustment of the height of the upper main pipe 300. When adjusting the height, the operator moves the adjusting screw 48 up and down. The adjusting screw 48 drives the upper ring plate 45, the upper support rod 44, and the upper main pipe 300 to move up and down through the connecting screw 47.
[0037] After the upper main pipe 300 position is adjusted, the adjusting screw 48 is fixed by adjusting nut 482; the protective sleeve 46 is fixedly installed, which provides daily protection for the corrugated hose 40, reducing the risk of dust particles impacting the corrugated hose 40, thereby effectively extending the service life of the corrugated hose 40. This screening device adopts a negative pressure dust collection method, which can effectively remove the dust generated during the screening process, solving the problem of dust adhering to surrounding equipment. Compared with existing technologies, it significantly improves the cleanliness of the surrounding environment and does not consume water resources.
[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
