Description

A dust collector for white fused alumina production Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to a dust collector for white fused alumina production. Background Technology

[0002] During the production of white fused alumina, processes such as crushing and grinding of raw materials generate a large amount of waste gas containing fine dust particles. If this waste gas is directly released into the atmosphere, it will not only cause serious air pollution and harm human health, but also have adverse effects on the surrounding ecological environment. Therefore, it is necessary to equip the facility with efficient dust removal equipment to treat the waste gas.

[0003] Traditional dust collectors typically employ a fixed filtration structure. When dust-laden gas passes through the filter material, dust particles gradually adhere to the surface of the filter material. As operating time increases, dust accumulates and rapidly clogs the pores of the filter material, leading to a sharp increase in gas flow resistance and a significant reduction in filtration efficiency. Consequently, frequent shutdowns are required for manual cleaning or replacement of the filter material, further impacting dust removal efficiency and equipment lifespan. To address these issues, we propose a dust collector for white fused alumina production to resolve the aforementioned problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a dust collector for white fused alumina production to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collector for white fused alumina production, comprising a dust collector cylinder, with an air inlet and an exhaust outlet at both ends of the dust collector cylinder, a bearing fixedly installed inside the dust collector cylinder, filter screens fixedly installed on both sides of the bearing inner ring, a fixing plate fixedly installed at the center of the two filter screens through an opening, air filter cotton installed between the two filter screens, a motor fixing cover installed inside the dust collector cylinder, a waterproof motor installed on the inner wall of the motor fixing cover, the output end of the waterproof motor fixedly connected to the center of the outer wall of the fixing plate, a liquid guide pipe installed on the top outer wall of the dust collector cylinder through an opening, a nozzle installed at one end of the liquid guide pipe, and the water spray end of the nozzle located at the center of the outer wall of the fixing plate.

[0006] Preferably, the outer wall of the dust collector is fixedly provided with an annular water supply pipe, and the inner wall of the annular water supply pipe is connected to an equally spaced atomizing nozzle through an opening. The atomizing nozzle is located inside the dust collector, and the bottom outer wall of the annular water supply pipe is connected to a liquid filling pipe through an opening.

[0007] Preferably, a fixing ring is installed on the inner wall of the dust collector, and the inner wall of the fixing ring is fixedly connected to the outer wall of the motor mounting cover through a bracket.

[0008] Preferably, the bottom outer wall of the dust collector is connected to two drain pipes through an opening, and the two drain pipes are respectively located on both sides of the bottom of the bearing.

[0009] Preferably, a positioning ring is fixedly provided on the outer wall of the air inlet, and the outer wall of the positioning ring has fixing openings distributed at equal intervals, and the inner wall of the fixing opening is equipped with a matching bolt.

[0010] Preferably, an exhaust fan is fixedly provided on the inner wall of the exhaust port.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] By incorporating a rotatable filter screen and air filter cotton structure within the dust collector, and driven by a waterproof motor, the air filter cotton can rotate continuously. Water is sprayed out through the liquid guide pipe and a nozzle precisely positioned in the center of the fixed plate, which can evenly and thoroughly rinse the rotating air filter cotton, effectively removing dust particles attached to its surface. This avoids the problem of reduced filtration efficiency caused by dust accumulation in traditional dust collectors, reduces the frequency and difficulty of manual cleaning, lowers maintenance costs, and extends the service life of the equipment.

A positioning ring 4 is fixedly welded to the outer wall of the air inlet 2. The positioning ring 4 is an annular metal piece with evenly distributed fixing openings 5 ​​on its outer wall. Each fixing opening 5 is a circular through hole with threads tapped on its inner wall, which can be fitted with suitable bolts for connecting and fixing the dust collector to the dust discharge pipe of the white fused alumina production equipment.

[0024] Example 2

[0025] Based on Embodiment 1, a bearing 9 is installed inside the dust collector 1. The bearing 9 is made of a high-temperature resistant and wear-resistant material, and filter screens 11 are fixedly connected to its inner rings on both sides. Both filter screens 11 are circular metal meshes, and a fixing plate 10 is fixedly provided in the center of the two filter screens 11 through an opening. The fixing plate 10 is a circular metal sheet that fits tightly with the filter screens 11. An air filter cotton 12 is installed between the two filter screens 11. The air filter cotton 12 has a multi-layer structure and can effectively adsorb dust particles in the air.

[0026] Example 3

[0027] Based on Embodiment 1, the dust collector 1 is further provided with a motor fixing cover 13 inside. The motor fixing cover 13 is a cylindrical metal cover, and a waterproof motor is installed on its inner wall by bolts. The output end of the waterproof motor is fixedly connected to the center of the outer wall of the fixing plate 10 by a coupling. When the waterproof motor starts, it can drive the fixing plate 10, the two filter screens 11 and the air filter cotton 12 to rotate together. In order to ensure the stability of the motor fixing cover 13, a fixing ring 14 is installed on the inner wall of the dust collector 1. The fixing ring 14 is a ring-shaped metal part, and its inner wall is welded and fixed to the outer wall of the motor fixing cover 13 by a bracket.

[0028] Example 4

[0029] Based on Embodiment 1, a liquid guide pipe 15 is installed on the top outer wall of the dust collector 1 through an opening. The liquid guide pipe 15 is a metal pipe, with one end connected to an external water source and the other end equipped with a nozzle 16. The water spray end of the nozzle 16 is located at the center of the outer wall of the fixed plate 10. When the water source is turned on, water is sprayed through the liquid guide pipe 15 and the nozzle 16 onto the rotating fixed plate 10, thereby cleaning the air filter cotton 12. An annular water supply pipe 6 is fixedly welded to the outer wall of the dust collector 1. The annular water supply pipe 6 is an annular metal pipe, and its inner wall is connected to atomizing nozzles 7 that are evenly distributed through an opening. The atomizing nozzles 7 are located inside the dust collector 1 and can spray water mist into the dust collector 1 to further adsorb dust in the air. A liquid filling pipe 8 is connected to the bottom outer wall of the annular water supply pipe 6 through an opening. The liquid filling pipe 8 is used to replenish water into the annular water supply pipe 6.

[0030] Example 5

[0031] Based on Embodiment 1, the bottom outer wall of the dust collector 1 is connected to two drain pipes 17 through an opening. The two drain pipes 17 are located on both sides of the bottom of the bearing 9, respectively, and are used to discharge the wastewater generated after cleaning the air filter cotton 12 and spraying water mist. An exhaust fan 18 is fixedly installed on the inner wall of the exhaust port 3. The exhaust fan 18 is started when the dust collector is working, which can accelerate the air flow inside the dust collector 1 and improve the dust removal efficiency.

[0032] Working principle of this utility model:

[0033] Referring to Figures 1-4 in the instruction manual, first connect and fix the positioning ring 4 at the air inlet 2 of the dust collector 1 to the dust discharge pipe of the white fused alumina production equipment through the fixing port 5 and the matching bolts. Start the white fused alumina production equipment, and the dust-laden gas enters the dust collector 1 from the air inlet 2. At the same time, the exhaust fan 18 on the inner wall of the exhaust port 3 starts synchronously, accelerating the flow of gas in the dust collector 1. The gas first passes through the rotating filter screen 11 and the air filter cotton 12. The air filter cotton 12 adsorbs most of the dust particles, achieving preliminary filtration. During the dust removal process, water can be supplied to the annular water supply pipe through the liquid addition pipe 8 as needed. 6. Water is added internally, and the water is sprayed into a mist through the atomizing nozzle 7 to further adsorb fine dust in the air and improve the dust removal effect. As the dust removal work continues, a lot of dust will accumulate on the surface of the air filter cotton 12, affecting the filtration efficiency. At this time, the external water source can be turned on, so that water is sprayed through the liquid guide pipe 15 and the nozzle 16 onto the rotating fixed plate 10, thereby cleaning the air filter cotton 12. The wastewater after cleaning is discharged from the drain pipes 17 on both sides of the bottom of the dust collector 1. After the white corundum production equipment stops working, the exhaust fan 18 and the external water source are turned off to complete this dust removal operation.
