Description

Technical Field

[0001] This utility model relates to the field of alumina dust removal technology, and in particular to an alumina dust collector. Background Technology

[0002] In the production processes of alumina smelting, powder processing, and conveying, a large amount of suspended alumina dust is generated. This dust particles are fine and easily dispersed, which not only pollutes the working environment and harms the respiratory system of operators, but may also adhere to the surface of production equipment, affecting precision and even causing safety hazards. Existing dust collectors are mostly single-inlet designs, which are prone to uneven filtration due to airflow turbulence. Moreover, the filter media is often easily damaged due to insufficient high-temperature resistance. At the same time, dust easily clogs the filter pores, requiring frequent shutdowns for cleaning, which reduces dust removal efficiency and increases maintenance costs. Some equipment has poor sealing performance and air leakage problems, further weakening the dust removal effect and making it difficult to meet the needs of efficient and continuous alumina dust treatment, which brings certain adverse effects to the use process. In order to overcome the shortcomings of existing technologies, we propose an alumina dust collector. Utility Model Content

Two air inlet pipes are symmetrically fixed to the top of the dust collection tank, and exhaust pipes are fixedly connected to both sides of the tank. A support frame is fixedly connected to the lower end of the dust collection tank, and a servo motor is detachably connected to the top of the tank. The output shaft of the servo motor is detachably connected to a rotating rod, and a cross-shaped connecting plate is fixedly connected to the lower end of the rotating rod. A dust collection cylinder is fixedly connected to the outer surface of the cross-shaped connecting plate. Multiple filter plates are detachably embedded on the outer surface of the dust collection cylinder. A first fixing ring is fixedly connected to the outer surface of the dust collection cylinder, and multiple first... The dust collector has a second fixed ring fixedly connected to its upper end, and a third fixed ring fixedly connected to its upper inner surface. Multiple second balls are rolled between the second and third fixed rings. A discharge valve is detachably connected to the lower end of the dust collector, passing through the dust collector. A fixed cylinder is fixedly connected to the upper inner surface of the dust collector. Multiple fixed plates are fixedly connected to the outer surface of the fixed cylinder. A rectangular groove is provided in the fixed plate. A spring is detachably connected to the rectangular groove. One end of the spring abuts against a limit plate. A connecting rod is detachably connected to one end of the limit plate. A soft brush is fixedly connected to the other end of every two connecting rods.

[0005] Preferably, the filter plate is made of high-temperature resistant glass fiber filter material, and the filter plates are distributed at equal intervals along the circumference of the dust collector cylinder, and there are multiple filter plates. The filter plates are connected to the dust collector cylinder by bolt detachable connection. The outer surface of the dust collector cylinder is provided with an insert groove that is compatible with the filter plate, and the inner wall of the insert groove is provided with a sealing strip.

[0006] Preferably, both the first ball and the second ball are made of stainless steel, and the inner wall of the first fixing ring is provided with a first annular groove that matches the first ball, the inner wall of the dust collector is provided with a first guide ring groove at the position corresponding to the first annular groove, one side surface of the third fixing ring is provided with a second annular groove that matches the second ball, and one side surface of the second fixing ring is provided with a second guide ring groove at the position corresponding to the second annular groove.

[0007] Preferably, the bristles of the soft-bristled brush are made of wear-resistant nylon, and the bristle length is adapted to the thickness of the filter plate. The free ends of the bristles are tightly attached to the outer surface of the filter plate. The fixing plates are evenly distributed along the circumference of the fixing cylinder, and the number is the same as the number of filter plates. The fixing plates and the fixing cylinder are integrally formed.

[0008] Preferably, the servo motor is detachably connected to the top of the dust collector via a flange, with a rubber sealing gasket sandwiched between the flanges.

The dust collector is made of Q235 carbon steel, and the inner wall of the dust collector is coated with an epoxy resin anti-corrosion coating.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This alumina dust collector uses symmetrical and synchronous air intake through dual air inlet pipes, and a servo motor drives the dust collection cylinder to rotate. The first and second ball bearings, respectively, roll between the first fixed ring and the dust collection tank, and between the second fixed ring and the third fixed ring, to ensure stable rotation of the dust collection cylinder. By utilizing the synergistic effect of centrifugal force and high-temperature resistant glass fiber filter media, it efficiently traps alumina dust, avoiding the uneven filtration problem caused by airflow turbulence in traditional dust collectors. Clean gas is quickly discharged through the exhaust pipes on both sides, significantly improving the overall dust removal efficiency and meeting the high-efficiency separation requirements of alumina dust.

[0011] This alumina dust collector uses a spring inside the fixed plate to continuously apply force to the limiting plate, ensuring that the soft brush is always in close contact with the outer surface of the filter plate. This allows for simultaneous cleaning of the filter surface as the dust collector rotates, preventing dust from clogging the filter pores at the source and reducing downtime for cleaning. The filter plate is connected by detachable bolts and features a sealing strip with an embedded groove, making replacement convenient and ensuring a good seal. A pneumatic butterfly valve allows for rapid dust discharge, solving the problems of cumbersome maintenance and poor continuous operation of traditional equipment. This effectively reduces maintenance costs and extends the continuous operating time of the equipment. Attached Figure Description

[0015] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an alumina dust collector includes a dust collection tank 1. Two air inlet pipes 2 are symmetrically fixed to the top of the dust collection tank 1, and exhaust pipes 3 are fixedly connected to both sides. A support frame 4 is fixedly connected to the lower end of the tank. A servo motor 5 is detachably connected to the top of the tank via a flange with a rubber sealing gasket. The output shaft of the servo motor 5 is detachably connected to a rotating rod 6 with a wear-resistant ceramic coating on its outer surface via a coupling. A cross-shaped connecting plate 7 is fixedly connected to the lower end of the rotating rod 6. A dust collection cylinder 8 is fixedly connected to the outer surface of the cross-shaped connecting plate 7. The outer surface of the dust collection cylinder 8 is open. The dust collector 8 has an inner wall with a sealing strip for mounting, and multiple filter plates 9 made of high-temperature resistant glass fiber filter material are detachably mounted thereon with bolts, evenly spaced along its circumference. A first fixing ring 10 is fixedly connected to the outer surface of the dust collector 8. A first annular groove is formed on the inner wall of the first fixing ring 10. A first guide ring groove is formed on the inner wall of the dust collector 1 at the position corresponding to the first annular groove. Multiple stainless steel first ball bearings 11 are rolled between the two. A second fixing ring 12 is fixedly connected to the upper end of the dust collector 8. The upper inner surface of the dust collector 1 is fixed. A third fixing ring 13 is connected, and a second annular groove is formed on one side of the third fixing ring 13. A second guide ring groove is formed on one side of the second fixing ring 12 at the position corresponding to the second annular groove. Multiple stainless steel second ball bearings 14 are rolled between the two. A pneumatic butterfly valve type discharge valve 15 is detachably connected to the lower end of the dust collector cylinder 8 through the dust collector tank 1. A metal sealing ring is provided at the connection position between the discharge valve 15 and the dust collector cylinder 8. A fixing cylinder 16 is also fixedly connected to the inner surface of the upper end of the dust collector tank 1. The outer surface of the fixing cylinder 16 is integrally formed. There are multiple fixed plates 17 distributed at equal intervals along their circumference, and the number of fixed plates 17 is the same as that of filter plates 9. A rectangular groove 18 is opened in the fixed plate 17. A spring 19 is detachably connected in the rectangular groove 18. One end of the spring 19 abuts against a limiting plate 20. One end of the limiting plate 20 is detachably connected to a connecting rod 21. The other end of every two connecting rods 21 is fixedly connected to a soft bristle brush 22 made of nylon wear-resistant soft bristles, with the bristle length adapted to the thickness of the filter plate 9 and the free end of the bristles tightly attached to the outer surface of the filter plate 9.

[0016] It should be noted that this utility model is an alumina dust collector. In use, gas containing alumina dust is simultaneously introduced into the dust collection tank 1 through two inlet pipes 2. The servo motor 5 is started, driving the rotating rod 6 to rotate, which in turn drives the dust collection cylinder 8 to rotate synchronously through the cross connecting plate 7.

The alumina dust in the dust-laden gas is trapped inside the dust collection cylinder 8 under the action of centrifugal force and the filtration effect of the filter plate 9. The filtered clean gas is discharged through the exhaust pipes 3 on both sides of the dust collection tank 1. Simultaneously, as the dust collection cylinder 8 rotates, the fixed cylinder 16... The fixed plate 17 on the upper part continuously applies elastic force to the limiting plate 20 through the spring 19 in the rectangular groove 18, so that the soft bristle brush 22 connected to the connecting rod 21 is always in close contact with the outer surface of the filter plate 9 and cleans it, so as to avoid dust clogging the pores of the filter plate 9. When the dust removal operation has been carried out for a set time, the servo motor 5 and the air intake of the air intake pipe 2 are turned off, and the discharge valve 15 is opened to discharge the alumina dust trapped in the dust removal cylinder 8 through the discharge valve 15, thus completing one dust removal operation. If the filter plate 9 is damaged or the filtration efficiency decreases and needs to be replaced, the bolts used to fix the filter plate 9 on the outer surface of the dust removal cylinder 8 can be removed after the equipment is turned off, the old filter plate 9 can be removed and a new filter plate 9 can be replaced, and then the new filter plate 9 can be fixed in the mounting groove with bolts for continued use.
