Description

Technical Field

[0001] This utility model relates to the field of dust recovery technology, and in particular to a centralized dust recovery device for prebaked anode production workshops. Background Technology

[0002] Prebaked anodes are an important material used in aluminum electrolysis cells. The main production processes include raw material crushing, screening, conveying, mixing, molding and roasting. A large amount of dust may be generated during the production process, requiring effective recycling equipment to reduce pollution and protect workers' health.

[0003] The existing dust collection equipment in prebaked anode production workshops has a relatively simple structure. Asphalt tar is sticky, and when mixed with dust, it increases the adhesion between dust particles, making them prone to adsorption and clumping, which leads to blockage, affects filtration efficiency and service life, hinders dust collection, makes it difficult to remove sticky dust, and results in incomplete dust removal and low cleaning efficiency.

[0004] Therefore, in response to the problems of existing centralized dust collection equipment being prone to clogging and affecting filtration efficiency, and the difficulty in removing sticky dust, a centralized dust collection equipment for prebaked anode production workshop can be designed.

A tank cover 2 is provided at the upper end of the dust collection tank 1, and an air outlet pipe 3 is fixedly connected to the upper end of the tank cover 2. A fan 4 is fixedly connected to the rear end of the air outlet pipe 3, located above the tank cover 2. An air inlet pipe 5 is fixedly connected to the front end of the dust collection tank 1. A partition plate 6 is fixedly connected to the lower end of the interior of the dust collection tank 1, and a rotating seat 7 is rotatably connected to the upper end of the partition plate 6. A scraper 8 is fixedly connected to the outer side of the rotating seat 7, and a filter cylinder 9 is fixedly connected to the upper end of the rotating seat 7. A cleaning brush 10 is provided on the left side of the filter cylinder 9. A dust collection pipe 11 is fixedly connected to the lower left side of the dust collection tank 1, and a conveying roller 12 is rotatably connected inside the dust collection pipe 11. During operation, the fan 4 generates suction, drawing dusty air from the production workshop into the inlet duct 5. The rotating seat 7 drives the filter cylinder 9 to rotate at a low speed, ensuring even contact between the filter cylinder 9 and the dusty airflow, thus intercepting and filtering the dust and improving filtration efficiency. The cleaning brush 10 uses high-frequency micro-vibration to thoroughly clean the rotating filter cylinder 9, effectively removing the sticky dust adhering to its surface and sweeping it onto the partition plate 6. Simultaneously, the rotating seat 7 drives the scraper 8 to rotate and scrape the partition plate 6, drawing the dust into the dust collection pipe 11 for centralized dust collection. This process is highly automated, offers good overall flexibility, and improves cleaning and dust removal efficiency. The rotating conveyor roller 12 outputs the collected dust, and the purified air is then discharged from the outlet duct 3, achieving centralized dust recovery and air purification.

[0024] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, a low-speed motor 13 is fixedly connected to the upper end of the inner wall of the dust collection tank 1. The output shaft of the low-speed motor 13 movably passes through the partition plate 6 and is fixedly connected to the rotating seat 7. The low-speed motor 13 drives the rotating seat 7 to rotate at a low speed. The low-speed rotation helps the filter cylinder 9 to evenly contact the dust-laden airflow, improves the filtration efficiency, and avoids excessive local dust accumulation. Three cleaning scrapers 8 are arranged in a circular array. The lower end of the cleaning scraper 8 contacts the partition plate 6. The rotating seat 7 drives the cleaning scraper 8 to rotate and clean the partition plate 6. The left end of the inner wall of the dust collection tank 1 is fixedly connected to... A support base 14 is provided, with a piezoelectric ceramic plate 15 fixedly connected to its upper end. The right side of the upper end of the support base 14 and the upper end of the inner wall of the dust collection tank 1 are fixedly connected via a vibration transmission rod 16. The outer side of the vibration transmission rod 16 is fixedly connected to a cleaning brush 10. Brush bristles are fixedly connected to one end of the cleaning brush 10 near the scraper 8. When the piezoelectric ceramic plate 15 is energized, it generates high-frequency vibration, which is transmitted to the cleaning brush 10 through the vibration transmission rod 16, causing the brush bristles to generate high-frequency micro-vibrations, effectively cleaning the sticky dust adhering to the surface of the filter cylinder 9. The filter cylinder 9 is coated with an oleophobic material. Inside the filter cylinder 9 is a high-efficiency filter layer 17, and inside the high-efficiency filter layer 17 is an activated carbon layer 18. The air outlet duct 3 and the activated carbon layer 18 are connected. The oleophobic material effectively reduces the adhesion of sticky dust to the surface of the filter cylinder 9, making the dust easier to detach and reducing accumulation. This helps maintain air permeability and filtration efficiency. The high-efficiency filter layer 17 and the activated carbon layer 18 can efficiently intercept and adsorb dust of different particle sizes, improving air quality and ensuring thorough centralized collection. The separator plate 6... A dust discharge port 19 is provided at the left end. The upper end of the dust collection pipe 11 is connected to the dust discharge port 19. A spiral blade 20 is fixedly connected to the outer side of the conveying roller 12. Dust is scraped into the dust collection pipe 11 from the dust discharge port 19. The spiral blade 20 rotates to convey and collect the dust. A conveying motor 21 is fixedly connected to the right end of the dust collection pipe 11. The output shaft of the conveying motor 21 is fixedly connected to the conveying roller 12. Four moving wheels 22 are provided at the lower end of the dust collection tank 1. The conveying motor 21 drives the conveying roller 12 to rotate. The moving wheels 22 facilitate the movement of the dust collection tank 1.

[0025] During operation, the fan 4 generates suction, drawing dusty air from the production workshop into the inlet duct 5. The low-speed motor 13 drives the rotating seat 7 and the filter cylinder 9 to rotate at low speed. The filter cylinder 9 evenly contacts the dusty airflow, intercepting and filtering the dust. The piezoelectric ceramic plate 15 is energized to generate high-frequency vibration, which is transmitted to the cleaning brush 10 through the vibration transmission rod 16, causing the brush bristles to generate high-frequency micro-vibration, thoroughly cleaning the rotating filter cylinder 9 and sweeping the dust onto the partition plate 6. The rotating seat 7 simultaneously drives the scraper 8 to rotate and scrape the partition plate 6, scraping the dust from the dust outlet 19 into the dust collection pipe 11. The conveying motor 21 drives the conveying roller 12 to rotate, and the spiral blades 20 output the collected dust. The purified air is then discharged from the outlet duct 3, thus achieving centralized dust recovery and air purification.

[0026] Through the above steps, the filter cylinder 9 rotates at low speed to intercept and filter dust, the cleaning brush 10 vibrates at high frequency to thoroughly clean the sticky dust, and the scraper 8 scrapes the dust into the dust collection pipe 11 to achieve centralized dust collection. The high degree of automation improves the efficiency of cleaning and dust removal, thus solving the problems of easy clogging and reduced filtration efficiency of existing centralized dust collection equipment, and the difficulty in removing sticky dust.
