Description

Technical Field

[0001] The present invention relates to the technical field of aluminum slag treatment, and more specifically to an aluminum slag recovery device for aluminum product production and a treatment method thereof. Background Art

[0002] Aluminum slag is produced during aluminum smelting. Some impure mixed metals form slag, which is a by-product of the aluminum smelting and forming process. As the main by-product of the aluminum industry, some aluminum can be separated and refined. Aluminum slag is produced in all processes where aluminum is melted. In the past, people regarded aluminum slag as waste and discarded it, which not only caused a waste of aluminum resources but also brought environmental problems.

[0003] In the aluminum slag recovery process, the problem of aluminum slag retention is common in the solid-liquid separation link. Aluminum slag is prone to form accumulation inside the separation device, causing equipment blockage. This phenomenon not only significantly reduces the separation efficiency of metallic aluminum, but also directly affects the purity of the final product. In addition, the airborne pollutants (including high-temperature flue gas and metal dust) generated during the aluminum block processing are usually directly discharged into the atmosphere without effective treatment, which not only aggravates air pollution in the surrounding area, but also poses potential health risks to the respiratory system of on-site workers. Occupational exposure problems in this working environment may cause long-term occupational health hazards. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 The filter bag 1 has two ends, and the end of the filter bag 1 is fixed with a circle, and a bottom end of the filter bag 1 is provided with a circle. The bottom end of the filter bag 1 is provided with a circle, and a bottom end of the filter bag 1 is provided with a circle.

[0030] The filter element also includes an inner cavity 2 12 opened on the inner lower end surface of the outer shell 1, and an impact ball 13 is fixedly installed on the inner lower end surface of the inner cavity 2 12. An impact ball 2 14 is fixedly installed on the lower end surface of the filter funnel 5 corresponding to the impact ball 13. There are multiple groups of impact balls 13 and 14, which are dispersed in a ring shape.

[0031] First, the aluminum liquid containing aluminum slag is discharged into the outer shell 1 through the feed pipe 3, and the motor 9 is started synchronously to rotate the driving gear 10. The driving gear 10 is engaged with the long gear 11 on the rotating shaft 8, so the rotating shaft 8 will rotate synchronously and carry the conical block 7 and the filter funnel 5 to rotate at high speed. The filter funnel 5 is provided with dense filter holes. When the filter funnel 5 rotates at high speed, centrifugal separation can be performed to retain the aluminum slag on the outer surface of the filter funnel 5, and the aluminum liquid is discharged into the lower side of the filter funnel 5. It can be discharged from the equipment through the sewage pipe and enter the external collection equipment. At the same time, the rotation of the filter funnel 5 will carry the impact ball 13 to rotate. The impact ball 13 is corresponding to the impact ball 2 14 inside the inner cavity 2 12. Therefore, when the impact ball 13 collides with the impact ball 2 14, the filter funnel 5 will rise, and then return to its original position under the action of the spring 15. In this way, as the filter funnel 5 rotates at high speed, high-speed vibration can be performed to prevent the aluminum slag from clogging the filter funnel 5.

[0032] The automatic filtering mechanism also includes an exhaust member arranged on the upper side of the interior of the outer shell 1. The exhaust member includes a fixing member 28 fixedly installed on the upper end surface of the outer shell 1. The fixing member 28 is arranged in an L-shape. An inner cavity 3 17 is opened inside the upper side of the rotating shaft 8. The inner cavity 3 17 is slidably connected to the piston plate 18. The upper end of the piston plate 18 is fixedly installed with a transmission column 16. The upper end of the transmission column 16 extends to the upper side of the rotating shaft 8 and is fixedly connected to the fixing member 28.

[0033] A cross bar 19 is provided on the upper side of the interior of the outer shell 1, and the cross bar 19 is fixedly connected to the rotating shaft 8. A connecting cavity 20 is provided inside the cross bar 19, and the connecting cavity 20 is interconnected with the inner cavity 17. A plurality of groups of air intake ports 21 are provided on the lower end surface of the cross bar 19, and the plurality of groups of air intake ports 21 are all interconnected with the connecting cavity 20.

[0034] An air outlet 29 is provided on the outer surface of the rotating shaft 8, and the air outlet 29 is communicated with the inner cavity three 17. The air outlet 29 is arranged between the outer shell 1 and the piston plate 18. The air outlet 29 is communicated with the external gas collecting equipment. A one-way output valve is provided inside the air outlet 29, and a one-way input valve is provided inside the communicating cavity 20.

[0035] Secondly, the high-speed vibration of the filter funnel 5 can make the rotating shaft 8 reciprocate synchronously, and the piston plate 18 is slidably connected to the inside of the inner cavity three 17. The piston plate 18 is fixedly connected to the fixing part 28 through the transmission column 16, that is, the piston plate 18 remains stationary during the reciprocating motion of the rotating shaft 8, that is, the piston plate 18 reciprocates inside the inner cavity three 17. When the piston plate 18 rises inside the inner cavity three 17, the one-way input valve inside the connecting cavity 20 will be opened, and the polluted gas inside the outer shell 1 will be sucked into the inner cavity three 17 through the air intake 21. When the piston plate 18 descends inside the inner cavity three 17, it will squeeze the gas inside the inner cavity three 17 and open the one-way output valve inside the air outlet 29 to discharge the polluted gas into the external gas collection equipment.

[0036] The automatic filtering mechanism also includes a slag discharge part arranged in the middle of the shell 1, and the slag discharge part includes a sleeve 22 fixedly installed on the inner wall of the shell 1. The lower end of the sleeve 22 is slidably connected to a vertical rod 25, and the lower end of the vertical rod 25 is fixedly installed with a scraper 23. The scraper 23 is arranged close to the filter funnel 5, and the other end of the scraper 23 is slidably connected to the conical block 7.

[0037] The upper end surface of the scraper 23 is fixedly mounted with multiple groups of stirring rods 27 , the outer side of the vertical rod 25 is provided with a notch 26 , and the outer edge of the upper end surface of the filter funnel 5 is fixedly mounted with a side plate 24 , and the notch 26 is slidably connected to the side plate 24 .

[0038] The upper end surface of the filter funnel 5 is provided with drainage grooves 30, and there are two groups of drainage grooves 30, which are symmetrically arranged. A drainage cavity 31 is provided inside the conical block 7. The two groups of drainage grooves 30 are interconnected with the drainage cavity 31, and the drainage cavity 31 is inclined.

[0039] The lower end surface of the housing 1 is rotatably connected to a discharge pipe 32 . The upper end of the discharge pipe 32 extends into the interior of the housing 1 and is fixedly connected to the filter funnel 5 . The discharge pipe 32 is communicated with the drainage cavity 31 .

[0040] The rotating shaft 8 carries the filter funnel 5 to rotate, and the scraper 23 remains stationary under the action of the sleeve 22 and the vertical rod 25, so that the aluminum liquid can be stirred and broken up to avoid the accumulation of aluminum slag. The combination of the sleeve 22 and the vertical rod 25 can offset the vibrating reciprocating motion of the filter funnel 5, ensuring that the scraper 23 always fits the filter funnel 5. The scraper 23 rotates to scrape off the aluminum slag filtered from the filter funnel 5 and discharge it into the drainage trough 30. The drainage trough 30 is tilted and enters the drainage chamber 31 under the action of gravity. The drainage chamber 31 is also tilted, so that the aluminum slag can be discharged into the discharge pipe 32, and then discharged into the external collection equipment through the discharge pipe 32 for subsequent recovery operations.

[0041] A method for processing aluminum slag recovery equipment used in aluminum product production, comprising the following steps:

[0042] S1: Waste Filtration: Aluminum liquid mixed with aluminum slag enters the housing 1 through the feed pipe 3. The driving motor 9 rotates and vibrates the filter funnel 5 to filter the aluminum slag in the aluminum liquid, thereby separating the aluminum slag and the aluminum slag, and discharging them separately from the equipment for subsequent processing;

[0043] S2: Waste gas removal: Toxic volatile gases generated during the filtration process of the aluminum liquid are sucked out of the equipment through the exhaust parts and enter the external waste gas treatment equipment for waste gas treatment;

[0044] S3: Waste removal: The filtered aluminum slag is scraped off from the filter funnel 5 into the interior of the drainage trough 30 through the slag removal piece, and finally discharged from the equipment through the discharge pipe 32 for recycling.

[0045] In the aluminum slag recovery process, there is a common problem of aluminum slag retention in the solid-liquid separation link. Aluminum slag is easy to form sedimentation inside the separation device, causing equipment blockage. This phenomenon not only significantly reduces the separation efficiency of metal aluminum, but also directly affects the purity of the final product. In addition, the airborne pollutants (including high-temperature flue gas and metal dust) generated during the aluminum block processing are usually directly discharged into the atmosphere without effective treatment, which not only aggravates the air pollution in the surrounding area, but also poses a potential health risk to the respiratory system of on-site workers. The occupational exposure problem in this working environment may cause long-term occupational health hazards. Therefore, this solution adopts an integrated automatic process. The filtering mechanism can simultaneously realize the treatment of gas-solid two-phase pollutants during the aluminum liquid purification stage. The high-efficiency exhaust components configured in the mechanism can capture the gaseous pollutants generated by the aluminum liquid filtration in real time, and transport them to the external purification device in a direction through a closed pipeline, effectively controlling the disorderly diffusion of productive waste gas. The dynamic slag discharge components equipped simultaneously adopt a mechanical cleaning mechanism to continuously remove the solid slag phase deposited on the separation interface, maintain the porosity of the filter medium stable, and prevent process blockage. This dual control mechanism not only solves the problem of airborne pollution in traditional processes, but also avoids the problem of system efficiency attenuation caused by solid phase retention, forming a closed-loop control system for the aluminum slag resource treatment process.

[0046] The filter funnel 5 is rotated at high speed, and the filter funnel 5 is rotated at high speed.

[0047] Secondly, the high-speed vibration of the filter funnel 5 can make the rotating shaft 8 reciprocate synchronously, and the piston plate 18 is slidably connected to the inner part of the inner cavity 17. The piston plate 18 is fixedly connected to the fixing member 28 through the transmission column 16. The piston plate 18 remains stationary during the reciprocating motion of the rotating shaft 8, that is, the piston plate 18 reciprocates inside the inner cavity 17. When the piston plate 18 rises inside the inner cavity 17, the one-way input valve inside the connecting cavity 20 is opened, and the polluted gas inside the housing 1 is sucked into the inner cavity 17 through the air intake 21. When the piston plate 18 descends inside the inner cavity 17, the gas inside the inner cavity 17 is squeezed and the one-way output valve inside the air outlet 29 is opened to discharge the polluted gas into the external gas collection device.

[0048] The rotating shaft 8 carries the filter funnel 5 to rotate, and the scraper 23 remains stationary under the action of the sleeve 22 and the vertical rod 25, so that the aluminum liquid can be stirred and broken up to avoid the accumulation of aluminum slag. The combination of the sleeve 22 and the vertical rod 25 can offset the vibrating reciprocating motion of the filter funnel 5, ensuring that the scraper 23 always fits the filter funnel 5. The scraper 23 rotates to scrape off the aluminum slag filtered from the filter funnel 5 and discharge it into the drainage trough 30. The drainage trough 30 is tilted and enters the drainage chamber 31 under the action of gravity. The drainage chamber 31 is also tilted, so that the aluminum slag can be discharged into the discharge pipe 32, and then discharged into the external collection equipment through the discharge pipe 32 for subsequent recovery operations.
