Description

Technical Field

[0001] The utility model relates to an aluminum ash cooling device, in particular to a novel high-temperature aluminum ash cooling device, belonging to the technical field of aluminum ash cooling. Background Art

[0002] A variety of by-products are produced during the aluminum smelting and forming process. As the main by-product of the aluminum industry, aluminum ash is produced in all aluminum melting processes. Aluminum ash is a hazardous waste and needs to be harmlessly treated before waste utilization. The harmless aluminum ash can be used as raw materials and admixtures for some products.

[0003] In the prior art, aluminum ash is often treated harmlessly by pyrometallurgical process, so that the nitride, carbide, fluoride, aluminum and other components in the aluminum ash are completely oxidized and decomposed or no longer reactive when exposed to water. 3 Because it is a pyrometallurgical process, the aluminum ash after treatment will be at high temperature. The last step is to cool the aluminum ash for subsequent transportation and packaging.

[0004] At present, in the cooling operation of aluminum ash, some enterprises adopt static and natural cooling methods. Although the cooling cost is low, it takes a long time and requires a large space for placement, which is inconvenient to operate; some enterprises use aluminum ash cooling devices, which use simple water cooling when cooling aluminum ash, and spray cooling water on the side wall of the drum to indirectly cool the aluminum ash in the drum. When the cooling water is sprayed on the side wall of the drum, it immediately flows down from the side wall of the drum. The cooling water stays on the side wall of the drum for a short time and evaporates quickly. The temperature of the aluminum ash inside the drum cannot be reduced, and a good cooling effect cannot be achieved. Utility Model Content

[0005] The technical solutions adopted by the utility model to solve the technical problems are as follows:

[0006] A novel high-temperature aluminum ash cooling device comprises a drum and a bracket, and also comprises a cooling unit, a drum rotation support unit, a transmission unit and a screening unit. The cooling unit comprises an air collecting hood, a water supply pipe, a guide plate, an exhaust port, a scraper trough, a water reservoir and a return pipe. A water reservoir is arranged above the bracket, a return pipe is arranged at the bottom of the water reservoir, a drum is arranged on the upper part of the water reservoir, a plurality of orderly arranged scraper troughs are arranged outside the drum, a part of the lower end of the drum is immersed in the water reservoir, a water supply pipe is arranged above the drum, an air collecting hood is arranged outside the drum, an exhaust port is arranged on the upper part of the air collecting hood, a guide plate is arranged inside the drum, a transmission unit is arranged at the rear end of the drum, a screening unit is arranged at the tail of the drum, and drum rotation support units are arranged at both ends of the drum.

[0007] The roller rotation support units at both ends of the roller include large supporting wheels, supporting wheel bearings, supporting wheel shafts and small supporting wheels. The large supporting wheels are arranged at both ends of the roller, the small supporting wheels support the roller body, the small supporting wheels are installed on the supporting wheel shafts, and supporting wheel bearings are arranged at both ends of the supporting wheel shafts. The large supporting wheels and the small supporting wheels cooperate with each other to support the rotation of the roller.

[0008] The transmission unit includes a driven gear, a gear bearing, a driving gear, a gear shaft, a coupling, a reducer and a motor. The motor drives the reducer to rotate. The reducer is connected to the gear shaft of the driving gear through a coupling. The driving gear is installed on the gear shaft. Gear bearings are provided at both ends of the gear shaft. The reducer drives the driving gear to rotate through the gear shaft. The driving gear drives the driven gear to rotate. The driven gear is welded to the drum. Therefore, when the driving gear drives the driven gear to rotate, the drum also rotates.

[0009] The screening unit comprises a screen, a coarse material outlet and a fine material outlet. The screen screens the cooled aluminum ash into coarse and fine particles, which are bagged and stored through the coarse material outlet and the fine material outlet respectively.

[0010] The water return pipe is provided with a control valve.

[0011] When in use, pour the high-temperature aluminum ash that needs to be cooled into the drum from the high-temperature aluminum ash inlet, start the motor, and the motor drives the reducer to rotate. The reducer is connected to the gear shaft of the driving gear through a coupling. The driving gear is installed on the gear shaft. Gear bearings are provided at both ends of the gear shaft. The reducer drives the driving gear to rotate through the gear shaft, and the driving gear drives the driven gear to rotate. The driven gear is welded on the drum. When the driving gear drives the driven gear to rotate, the drum also rotates. The high-temperature aluminum ash poured into the drum moves toward the rear end of the drum along the guide plate inside the drum under the action of the rotation of the drum. At this time, the water supply pipe on the drum supplies low-temperature cold water through the water pump and sprays it on the outer surface of the drum. The low-temperature cold water temperature conducts the low temperature from the outer surface of the drum to the inside of the drum through the drum wall, thereby cooling the high-temperature aluminum ash in the drum. The cold water sprayed on the surface of the drum will fall into the water reservoir at the bottom of the drum. When the water in the water reservoir is about to reach the top of the water reservoir, the return pipe control valve at the bottom of the water reservoir opens to let the water flow out, so that the water supply of the water supply pipe is the same as the return water of the return pipe, achieving water level balance, so that the water in the water reservoir always remains at a water level, so that the water in the water reservoir will not overflow or decrease. Since the outer surface of the lower end of the drum is immersed in the water reservoir, the drum is constantly rotating. Every time the drum rotates one circle, each part of the drum will pass through the water reservoir once. The low-temperature cold water in the water reservoir conducts the low temperature to the drum through the drum wall to cool the high-temperature aluminum ash in the drum. A scraper groove is provided on the outer surface of the drum. When the drum rotates, the scraper groove rotates with the drum. When the scraper groove rotates into the water reservoir, the low-temperature cold water in the water reservoir is injected into the scraper groove. As the drum continues to rotate, when the upper mouth of the scraper groove rotates to the downward direction, the water in the scraper groove will be sprinkled on the outer surface of the drum. The low-temperature cold water sprinkled on the outer surface of the drum conducts the low temperature to the inside of the drum through the drum wall, thereby cooling the high-temperature aluminum ash in the drum.

[0012] As cooling will generate water vapor, the water vapor is discharged from the exhaust port on the air collecting hood. The cooled aluminum ash flows along the guide plate inside the drum to the screen at the end of the drum. The screen can separate the aluminum ash into coarse and fine particles, which are bagged and stored through the fine material outlet and the coarse material outlet respectively.

[0013] The utility model sprays low-temperature cold water on the outer surface of the drum through a water supply pipe, which is the first cooling method; the outer surface of the drum is immersed in low-temperature cold water, which is the second cooling method; the scraper trough sprinkles low-temperature cold water on the outer surface of the drum, which is the third cooling method. The three cooling methods are carried out simultaneously, and the low-temperature cold water conducts the low temperature to the inside of the drum through the drum wall, cools the high-temperature aluminum ash inside the drum, improves the cooling efficiency of the high-temperature aluminum ash, and improves the production efficiency of the enterprise.

[0022] The transmission unit includes a driven gear 16, a gear bearing 18, a driving gear 19, a gear shaft 20, a coupling 21, a reducer 22 and a motor 23. The motor 23 drives the reducer 22 to rotate. The reducer 22 is connected to the gear shaft 20 of the driving gear 19 through the coupling 21. The driving gear 19 is installed on the gear shaft 20. Gear bearings 18 are provided at both ends of the gear shaft 20. The reducer 22 drives the driving gear 19 to rotate through the gear shaft 20. The driving gear 19 drives the driven gear 16 to rotate. The driven gear 16 is welded on the drum. When the driving gear 19 drives the driven gear 16 to rotate, the drum 1 also rotates.

[0023] The screening unit comprises a screen 17, a coarse material outlet 24 and a fine material outlet 25. The screen 17 screens the cooled aluminum ash into coarse and fine particles, which are bagged and stored through the coarse material outlet 24 and the fine material outlet 25 respectively.

[0024] A control valve 14 is provided on the return water pipe 15 .

[0025] When in use, high-temperature aluminum ash that needs to be cooled is poured into the interior of the drum 1 from the high-temperature aluminum ash inlet 11, and the motor 23 is started. The motor 23 drives the reducer 22 to rotate. The reducer 22 is connected to the gear shaft 20 of the driving gear 19 through the coupling 21. The driving gear 19 is installed on the gear shaft 20. Gear bearings 18 are provided at both ends of the gear shaft 20. The reducer 22 drives the driving gear 19 to rotate through the gear shaft 20. The driving gear 19 drives the driven gear 16 to rotate. The driven gear 16 is welded on the drum 1. When the driving gear 19 drives the driven gear 16 to rotate, the drum 1 also rotates. The high-temperature aluminum ash poured into the drum moves toward the rear end of the drum along the guide plate 4 inside the drum under the action of the rotation of the drum. At this time, the water supply pipe 3 on the drum supplies low-temperature cold water through a water pump and sprays it on the outer surface of the drum 1. The low-temperature cold water temperature conducts the low temperature from the outer surface of the drum to the inside of the drum through the drum wall, thereby cooling the high-temperature aluminum ash in the drum. The cold water sprayed on the drum surface will fall into the water reservoir 13 at the bottom of the drum.

Since the outer surface of the lower end of the drum is immersed in the water reservoir, the drum is constantly rotating. Every time the drum rotates a circle, each part of the drum will pass through the water reservoir once. The low-temperature cold water in the water reservoir conducts the low temperature to the drum through the drum wall, cooling the high-temperature aluminum ash in the drum. A scraper groove 6 is provided on the outer surface of the drum 1. When the drum rotates, the scraper groove 6 rotates with the drum 1. When the scraper groove 3 rotates to the inside of the water reservoir 13, the low-temperature cold water in the water reservoir 13 is injected into the scraper groove 6. As the drum 1 continues to rotate, when the upper opening of the scraper groove 6 rotates to the downward direction, the water in the scraper groove 6 will be sprinkled on the outer surface of the drum 1. The low-temperature cold water sprinkled on the outer surface of the drum conducts the low temperature to the drum through the drum wall, cooling the high-temperature aluminum ash in the drum.

[0026] As cooling generates water vapor, the water vapor is discharged from the exhaust port 5 on the air collecting hood 2. The cooled aluminum ash flows along the guide plate 4 in the drum to the screen 17 at the rear of the drum, and the screen 17 can screen the aluminum ash into coarse and fine particles, which are bagged and stored through the fine material outlet 25 and the coarse material outlet 24 respectively.

[0027] The utility model sprays low-temperature cold water on the outer surface of the drum through a water supply pipe, which is the first cooling method; the outer surface of the drum is immersed in low-temperature cold water, which is the second cooling method; the scraper trough sprinkles low-temperature cold water on the outer surface of the drum, which is the third cooling method. The three cooling methods are carried out simultaneously, and the low-temperature cold water conducts the low temperature to the inside of the drum through the drum wall, cools the high-temperature aluminum ash inside the drum, improves the cooling efficiency of the high-temperature aluminum ash, and improves the production efficiency of the enterprise.
