Description

Technical Field

[0001] This utility model relates to the field of aluminum ash slag treatment technology, and in particular to a harmless aluminum ash slag classification and treatment device. Background Technology

[0002] The electrolytic aluminum, aluminum processing, and recycled aluminum smelting processes generate a large amount of solid waste. This solid waste mainly contains metallic aluminum, aluminum oxide, aluminum nitride, and salts. These substances are collectively referred to as aluminum ash (or simply aluminum ash). Aluminum ash poses the following environmental hazards: First, it contains a large amount of ultrafine dust, which can easily lead to PM2.5 exceeding the standard. Second, when aluminum ash comes into contact with water, it can release ammonia and other dangerous chemical gases, which can easily pollute the atmospheric environment and threaten human health. Finally, aluminum ash also contains unstable fluoride ions, which pose a risk of polluting the land and groundwater. Therefore, aluminum ash must be treated in a harmless manner.

[0003] According to the announcement number (CN217411471U), a screening device for waste aluminum processing with a classification and collection function includes a hopper and a rectangular screen, as well as two support plates, a reciprocating shaking mechanism and a vibration mechanism. The two support plates are vertically arranged and symmetrically distributed from left to right. The hopper can be vertically slidably arranged above and between the two support plates. When waste aluminum is placed in the hopper, it falls into the rectangular screen through the discharge port on the lower side of the hopper. At the same time, a servo motor is started, which drives two cranks and a reciprocating lead screw to rotate. The rotation of the two cranks can reciprocate to move two connecting rods up and down, and the two connecting rods can drive the hopper to vibrate up and down, thus preventing the waste aluminum in the hopper from clogging.

[0004] However, in the process of sorting aluminum ash slag using the above method, the rectangular screen vibrates, causing the aluminum ash slag particles to continuously collide with the screen and with each other. This causes some fine particles to separate from the larger particles and drift into the air. Since the above method does not have a dust collection device, the aluminum ash slag dust that drifts into the air may be inhaled into the lungs of nearby operators, and prolonged inhalation will affect their health. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a harmless aluminum ash slag sorting and treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] In one embodiment, the multi-screening assembly includes two screens fixedly installed inside a sorting cylinder. The sorting cylinder is divided into three areas by the two screens. Each screen has multiple screen holes. Circular holes are provided at the center of both screens and the sorting cylinder. All three circular holes are located outside the first suction pipe. Multiple first suction nozzles are provided on the bottom side of the first suction pipe, and the multiple first suction nozzles are located in the three areas respectively.

[0010] In one embodiment, the outer side of the sorting cylinder is provided with a plurality of first sieve holes, second sieve holes and third sieve holes, the first sieve holes, second sieve holes and third sieve holes are respectively located on the outer side of three regions, and the size of the plurality of third sieve holes is the same as the sieve holes opened on the two sieve plates.

[0011] In one embodiment, the blocking assembly includes an electric push rod fixedly installed on one side of the sorting cylinder. The output end of the electric push rod passes through the sorting cylinder and the right-side sieve disc and is fixedly fitted with two baffles, which are located on one side of the two sieve discs respectively.

[0012] In one embodiment, a side plate is fixedly installed on one side of the base plate. The side plate is inclined, and a rotary motor is fixedly installed on one side of the side plate.

The dust that has been absorbed will enter the dust box from the first and second suction pipes respectively for storage, so as to facilitate subsequent unified processing. By setting up the first and second suction pipes, dust can be collected simultaneously during the sorting and collection process, thereby preventing aluminum ash slag dust that floats into the air from being inhaled by personnel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 A harmless aluminum ash slag sorting and treatment device includes a base plate 1, a collection box 2 fixedly installed on the top side of the base plate 1, a sorting and storage component inside the collection box 2, a sorting cylinder 7 above the collection box 2, a feed inlet 16 on one side of the sorting cylinder 7, a multi-screening component inside the sorting cylinder 7, and the sorting cylinder 7 is inclined. A fixing frame 17 is fixedly installed on one side of the base plate 1, a top plate 18 is fixedly installed on the top side of the fixing frame 17, and a dust box 19 and a fan are fixedly installed on the top side of the top plate 18. 20. A filter plate 26 is installed inside the dust bin 19. A connecting pipe 21 is fixedly installed on one side of the fan 20, and the other end of the connecting pipe 21 extends into the dust bin 19. A first suction pipe 22 and a second suction pipe 24 are fixedly installed on both sides of the dust bin 19, respectively. The other ends of the first suction pipe 22 and the second suction pipe 24 extend into the sorting cylinder 7 and the collection box 2, respectively. A blocking component is provided on the outside of the sorting cylinder 7. With the fan 20 and the dust bin 19 installed, the fan 20 is activated during the sorting process. Furthermore, because the bottom of the first suction pipe 22 is equipped with three first suction nozzles 23, and because the three first suction nozzles 23 are located in three different areas, each first suction nozzle 23 can individually absorb the dust generated in each area. By suctioning, the dust can be effectively prevented from entering the air and being inhaled by people nearby, thus avoiding potential health hazards. With the first suction pipe 22, the sucked-in dust will accumulate in the dust box 19 for subsequent unified processing. With the second suction pipe 24, and the three second suction nozzles 25 on the bottom of the second suction pipe 24 located in three different areas within the collection box 2, the dust generated by falling aluminum slag in the collection box 2 can be absorbed. The absorbed dust will then enter the dust box 19 through the second suction pipe 24 for storage. By setting up the first suction pipe 22 and the second suction pipe 24, dust can be collected simultaneously during the sorting and collection process, making the suction more comprehensive and achieving the harmless treatment of aluminum slag.

[0024] according to Figure 1 and Figure 2As shown, the classification and storage component includes a collection box 2 with two partitions 3 fixedly installed inside. The collection box 2 is divided into three areas by the two partitions 3. Each area is fixedly equipped with a set of guide plates 4. There are two guide plates 4 in each set, and they are arranged symmetrically. The bottom side of the second suction pipe 24 is equipped with multiple second suction nozzles 25, which are located in the three areas respectively. The two partitions 3 inside the collection box 2 divide the collection box 2 into three areas, so that aluminum ash slag of larger, medium and large volume can be classified and collected at the same time. The guide plates 4 in each area can guide the falling aluminum ash slag and also block the dust, so that the dust generated when the aluminum ash slag falls into the collection box 2 will not float out directly from the collection box 2.

[0025] according to Figure 2 and Figure 3 As shown, the multi-screening assembly includes a sorting cylinder 7 with two screen plates 10 fixedly installed inside. The sorting cylinder 7 is divided into three areas by the two screen plates 10. Each screen plate 10 has multiple screen holes. A circular hole is also provided at the center of both screen plates 10 and the sorting cylinder 7. All three circular holes are located outside the first suction pipe 22. Multiple first suction nozzles 23 are provided on the bottom side of the first suction pipe 22, and these nozzles are located in the three areas respectively. Multiple first screen holes 11, second screen holes 12, and third screen holes 13 are respectively provided on the outer side of the sorting cylinder 7. Located on the outer side of the three areas, the size of the multiple third sieve holes 13 is the same as that of the sieve holes opened on the two sieve discs 10. By opening multiple first sieve holes 11, second sieve holes 12 and third sieve holes 13, and arranging the first sieve holes 11, second sieve holes 12 and third sieve holes 13 in sequence, it is possible to classify aluminum ash slag from small to large, and the classification can be more accurate. Since the two round holes are located on the outer side of the first dust suction pipe 22, the first dust suction pipe 22 will not come into contact with the sieve disc 10 and the baffle 15. Therefore, the first dust suction pipe 22 will not be affected when the classification cylinder 7 rotates.

[0026] according to Figure 2 and Figure 3As shown, the blocking assembly includes an electric push rod 14 fixedly installed on one side of the sorting cylinder 7. The output end of the electric push rod 14 passes through the sorting cylinder 7 and the right-side screen plate 10 and is fixedly fitted with two baffles 15. The two baffles 15 are located on one side of the two screen plates 10 respectively. By setting the electric push rod 14, when aluminum ash slag in the sorting cylinder 7 is sorted, the electric push rod 14 drives the two baffles 15 to always be in contact with the two screen plates 10. When it is necessary to transfer aluminum ash slag in one area to another area, the electric push rod 14 will drive the two baffles 15 away from the screen plate 10. By setting two baffles 15, it is possible to prevent aluminum ash slag from entering other areas and accumulating during the screening process.

[0027] according to Figure 1-3 As shown, a side plate 8 is fixedly installed on one side of the base plate 1. The side plate 8 is inclined. A rotary motor 9 is fixedly installed on one side of the side plate 8. The output end of the rotary motor 9 rotates through the side plate 8 and is fixedly connected to one side of the sorting cylinder 7. A bracket 5 is fixedly installed on the bottom side of the base plate 1. A fixing ring 6 is fixedly installed on the top side of the bracket 5. The fixing ring 6 is inclined. The left end of the sorting cylinder 7 is rotatably set inside the fixing ring 6. By setting the rotary motor 9, when sorting is required, the rotary motor 9 can be started to drive the sorting cylinder 7 to rotate. By setting the fixing ring 6, the fixing ring 6 can play a supporting and limiting role, so that the sorting cylinder 7 remains stable when rotating.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0029] In use: Aluminum ash slag to be sorted is poured into the sorting cylinder 7 through the feed inlet 16. Then, the rotary motor 9 is started to rotate the sorting cylinder 7. Smaller aluminum ash slag will fall through the first screen hole 11 into the left side area of ​​the collection box 2. As the sorting cylinder 7 continues to rotate, all the smaller aluminum ash slag will fall into the left side area of ​​the collection box 2. Then, the electric push rod 14 is started to move the two baffles 15 backward, thus stopping the baffles 15 from blocking the screen plate 10. Then, aluminum ash slag of moderate and larger sizes will move through the screen holes of the left screen plate 10 to the middle area of ​​the sorting cylinder 7. Then, the electric push rod 14 is started again to move the baffles 15 forward, thus blocking the two screen plates 10. This prevents aluminum ash slag from accumulating in other areas during the screening process. When the moderate and larger aluminum ash slag enters the middle area, the rotary motor 9 continues to run, allowing the aluminum ash slag of moderate size to be sorted. The slag falls from the second screen hole 12 into the middle area of ​​the collection box 2. Then, the larger aluminum slag can be collected by following the above operation. The sorting cylinder 7 is set at an angle, which can greatly improve the effect of the screening process. The first screen hole 11, the second screen hole 12 and the third screen hole 13 are arranged in sequence, so the aluminum slag can be classified from small to large, and the classification can be more accurate. With the installation of a fan 20 and a dust box 19, the fan 20 is activated during the classification process. Because the bottom of the first suction pipe 22 is provided with three first suction nozzles 23, and the three first suction nozzles 23 are located in three areas, each first suction nozzle 23 can adsorb the dust generated in each area. The dust can be effectively prevented from entering the air and being inhaled by people nearby, which may cause health hazards. With the installation of the first suction pipe 22, the dust that is sucked in will accumulate in the dust box 19, which is convenient for subsequent unified treatment.
