Description

Technical Field

[0001] The present invention relates to the technical field of sorting devices, and specifically refers to a slag sorting device for electrolytic aluminum processing. Background Art

[0002] During the electrolytic aluminum processing, a large amount of slag is generated. These slags not only contain recyclable metallic aluminum and other valuable metals, but also are mixed with various impurities and dust. Efficiently sorting the slag to achieve resource recovery and reduce environmental pollution has always been an important issue in the electrolytic aluminum industry.

[0003] Currently, there are various slag sorting devices for electrolytic aluminum processing on the market. However, these traditional devices generally have some problems. On the one hand, when processing the slag material, most devices do not have an effective crushing function, resulting in large agglomerated slag materials being difficult to be fully broken. This not only easily causes the screen to be blocked, affecting the sorting efficiency, but also the large slag materials may impact the sorting equipment, reducing the service life of the equipment. On the other hand, the existing sorting mechanism has a relatively single movement mode, mostly only capable of simple up-and-down vibration or horizontal screening, unable to make the slag material be affected by multi-directional forces, resulting in poor stratification effect of the slag material, low probability of contacting and passing through the screen holes, and the screening accuracy and efficiency being difficult to meet the actual production requirements. In addition, during the sorting process, the dust in the slag is easy to escape, not only polluting the working environment, but also potentially harming the health of the operators. And the existing dust collection mechanism often operates independently, increasing the equipment cost and maintenance difficulty. Summary of the Invention

[0013] The beneficial effects of the present invention compared with the prior art are as follows: The reciprocating mechanism drives the material grinding disk to rotate reciprocally. With the cooperation of the material grinding convex columns, the large lumpy slag materials adhered to each other are crushed. While the particles of the crushed slag materials become smaller, it is avoided that the slag materials adhered to each other have too large particles to cause blockage to the sieve mesh, preventing the large lumpy slag materials from impacting and damaging the sorting mechanism. At the same time, the specific surface area of the crushed slag materials increases, which is convenient for subsequent recovery and separation of metallic aluminum and other valuable metals after classification. Specifically: 1. The material grinding disc reciprocates, and with the cooperation of the material grinding convex column, forces in different directions are alternately applied to the slag material, so that the stress on the slag material changes continuously, cracks are more likely to be generated and broken, and the time consumed for crushing the slag material is shortened. The reciprocating rotation causes the slag material to form a complex motion trajectory in the material grinding trough and the material grinding convex column. On the basis of the forward motion, there is also a flipping and stirring caused by the rotation change, which promotes the efficiency of slag crushing, and effectively avoids excessive aggregation or accumulation of slag material, improves the uniformity of slag distribution, and the reciprocating rotation makes the inertia force that needs to be overcome each time the material grinding disc is started and reversed smaller, the starting energy consumption is low, and the inertia and friction that need to be overcome by the same direction rotation are avoided. The reciprocating rotation makes the contact and force distribution between the material grinding convex column and the slag material more uniform, the wear is more balanced, the service life of the material grinding convex column is extended, and the maintenance cost of the device of the present invention is reduced; 2. When the sorting barrel is reciprocating up and down and rotating back and forth, the slag is subjected to multiple directional forces, which makes the mutual squeezing and dislocation between the slag layers more intense, and enhances the stratification effect. The up and down reciprocating motion gives the slag more opportunities to move perpendicular to the screen surface, increasing the probability of the slag contacting the screen hole and passing through the screen hole. The reciprocating rotation can make the slag constantly change its position and movement direction on the screen surface, avoiding the slag moving only in a single direction, resulting in low utilization rate of some screen holes, allowing more slag that meets the requirements of the screen hole to pass through the screen, improving screening efficiency and accuracy. Through this composite motion mode, the slag can be better turned, pushed and screened, which is suitable for slag in different forms such as block, granular or flake, and has stronger adaptability. Because its motion frequency and amplitude are relatively easier to adjust and control, the appropriate motion parameters can be selected according to the structural characteristics of the equipment and the characteristics of the slag, avoiding the resonance frequency of the equipment, reducing the damage to the equipment caused by resonance, and extending the service life of the equipment; 3. During the up and down reciprocating motion of the sorting slide, the cleaning connecting plate, the cleaning slide bar and the cleaning brush are driven to move synchronously through the cleaning top rod. With the cooperation of the cleaning spring, the cleaning brush synchronously reciprocates up and down to realize the cleaning operation of the filter plate and ensure the efficient filtering effect of the filter plate. Furthermore, the setting of the dust collecting chamber prevents ash and dust from accumulating at the lower end of the filter plate, further improving the smoothness of the airflow. Through the linkage effect, there is no need to set up a separate power component casing to clean the filter plate, thereby reducing the frequency and difficulty of maintenance.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Combined with the attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 5 and attached Figure 6As shown in the figure, a slag sorting device for electrolytic aluminum processing includes a machine shell 1. An inlet pipe 11 is provided at the upper end of the machine shell 1. A sorting mechanism 3 for sorting the slag is provided in the machine shell 1 and is communicated with the inlet pipe 11. The sorting mechanism 3 includes an ash discharge pipe 324 and a slag discharge pipe 325 extending out of the machine shell 1. A material grinding mechanism 2 for grinding the slag material is provided in the machine shell 1 and is communicated with the inlet pipe 11. The material grinding mechanism 2 includes a grinding disk 21 rotatably connected to the machine shell 1. A support frame 212 rotatably connected to the machine shell 1 is provided on the grinding disk 21. The support frame 212 is of a hollow structure. A plurality of grinding grooves 211 are equidistantly arranged along the circumferential direction on the grinding disk 21. Grinding studs 14 matched with the grinding grooves 211 are provided in the machine shell 1. An aggregate hopper 12 matched with the grinding disk 21 is provided on the machine shell 1. An outlet pipe 121 extending into the sorting mechanism 3 is provided at the lower end of the aggregate hopper 12. A uniform distribution frame 13 is provided in the outlet pipe 121. A uniform distribution hopper 131 is provided on the uniform distribution frame 13. The uniform distribution hopper 131 is of an umbrella-shaped structure. A reciprocating mechanism for driving the grinding disk 21 to rotate reciprocally is provided at the upper end of the machine shell 1. The reciprocating mechanism drives the sorting mechanism 3 to sort the slag. A dust collection mechanism 4 driven by the sorting mechanism 3 to collect the dust escaping during the sorting process is communicated at the lower end of the machine shell 1.

[0030] The working principle of the present invention: The slag mixture enters the machine shell 1 through the inlet pipe 11 under the action of gravity, contacts the grinding disk 21 and falls into the grinding grooves 211. The ash material, being relatively fine, falls into the aggregate hopper 12 under the action of gravity. Then, the ash material enters the sorting mechanism 3 through the outlet pipe 121 for sorting operations. At the same time, the reciprocating mechanism drives the grinding disk 21 to rotate reciprocally. The grinding disk 21 drives the grinding grooves 211 to rotate synchronously. During the rotation of the grinding grooves 211, the slag material is driven to rotate and contacts the grinding studs 14. The large lumps of slag adhered to each other are crushed under the combined action of impact, extrusion and shear force. The dispersed slag material falls under the action of gravity, passes through the aggregate hopper 12 and enters the sorting mechanism 3 for sorting. After being crushed, the slag particles become smaller, avoiding blockage of the screen caused by the large and adhered slag particles. Further, it prevents large lumps of slag from causing impact damage to the sorting mechanism 3. Moreover, the specific surface area of the crushed slag increases, facilitating the subsequent recovery and separation of metallic aluminum and other valuable metals therein after classification.

[0031] Combined with the attached Figure 4 、attached Figure 5 and attached Figure 6As shown in the figure, a fixing frame 22 is provided at the upper end of the casing 1. A fixing sliding groove 221 and a fixing arm 222 are provided on the fixing frame 22. A fixing slider 23 is slidably arranged in the fixing sliding groove 221. A mating rack 231 is provided on one side of the fixing slider 23. A milling gear 213 meshing with the mating rack 231 is provided at the upper end of the milling disc 21. The reciprocating mechanism includes a driving motor 243 arranged at the upper end of the casing 1. A driving rotating column 24 is provided at the output end of the driving motor 243. A driving sheave 241 and a driving bevel gear 242 are provided on the driving rotating column 24. The driving bevel gear 242 cooperates with the sorting mechanism 3; A power sheave 223 rotatably connected to the driving sheave 241 by a belt is arranged on the fixing arm 222. A power support arm 224 is provided at the lower end of the power sheave 223. A power slider 225 is rotatably arranged at one end of the power support arm 224. A mating sliding groove 232 slidably matched with the power slider 225 is provided at the upper end of the fixing slider 23. The mating sliding groove 232 is perpendicular to the fixing slider 23.

[0032] Working principle of the reciprocating mechanism: The driving motor 243 drives the driving rotating column 24 to rotate. The driving sheave 241 and the driving bevel gear 242 rotate synchronously. The driving bevel gear 242 drives the sorting mechanism 3 to sort the ash slag mixture. The driving sheave 241 drives the power sheave 223 to rotate through a belt. During the rotation of the power sheave 223, the power slider 225 is driven to perform circular rotation synchronously through the power support arm 224. Under the sliding limit of the mating sliding groove 232 slidably matched with the power slider 225, the fixing slider 23 slides reciprocally along the fixing sliding groove 221. The mating rack 231 slides reciprocally synchronously. The mating rack 231 drives the milling disc 21 to rotate reciprocally through the milling gear 213 meshing with it. The milling disc 21 alternately applies forces in different directions to the slag material, so that the stress received by the slag material changes continuously, making it easier to generate cracks and achieve crushing, and shortening the time-consuming for crushing the slag material; At the same time, the reciprocating rotation makes the slag material form a complex movement trajectory in the milling groove 211 and the milling convex column 14. On the basis of the forward movement, there are also flipping and stirring caused by the change of rotation, promoting the efficiency of crushing the slag material. Further, due to continuously changing the movement direction and position of the slag material, it effectively avoids the excessive aggregation or accumulation of the slag material and improves the uniformity of the slag material distribution; Moreover, the reciprocating rotation makes the inertial force required for the milling disc 21 to start and reverse each time smaller, the starting energy consumption is lower, avoiding the inertia and friction that need to be overcome for the same-direction rotation. The reciprocating rotation makes the contact and acting force distribution between the milling convex column 14 and the slag material more uniform, the wear is more balanced, prolonging the service life of the milling convex column 14 and reducing the maintenance cost of the device of the present invention.

[0033] Combined with attached Figure 2 、attached Figure 3 、attached Figure 8 、attached Figure 9 and attachedFigure 10 As shown in the figure, the sorting mechanism 3 includes support chutes 15 arranged inside the housing 1. Two groups of support chutes 15 are symmetrically arranged. A sorting carriage 31 is slidably arranged in the support chutes 15. The sorting carriage 31 is of an annular structure. A positioning chute 312 is arranged on the sorting carriage 31. A sorting barrel 32 is rotatably arranged in the positioning chute 312. A plurality of sieve plates 321 are arranged in the sorting barrel 32. The sieve plates 321 are of an umbrella shape. The plurality of sieve plates 321 are arranged in sequence from large to small in terms of aperture. A dust discharge pipe 324 is connected to the lower end of the sorting barrel 32 in a communicating manner. A slag discharge pipe 325 is connected to the side wall of the sorting barrel 32 in a communicating manner. The slag discharge pipe 325 is arranged corresponding to the sieve plates 321. Both the dust discharge pipe 324 and the slag discharge pipe 325 can be freely stretched and bent. A tremor mechanism is arranged in the housing 1, which is driven by the driving bevel gear 242 to drive the sorting barrel 32 to move up and down reciprocally while rotating reciprocally. The upper end of the sorting barrel 32 is hermetically connected with a sealing cover 323. The sealing cover 323 is hermetically connected with the discharge pipe 121. The sealing cover 323 can be freely stretched and bent.

[0034] Working principle of the sorting mechanism 3: The tremor mechanism drives the sorting barrel 32 to move up and down reciprocally while rotating reciprocally. The sorting barrel 32 drives the plurality of sieve plates 321 to move synchronously. During this process, since the diameter of the ash material is smaller than the aperture of the sieve plates 321, the ash material will directly fall through the plurality of sieve plates 321 under the action of gravity and enter the bottom of the sorting barrel 32 and flow out through the dust discharge pipe 324. Different-sized slag materials are gradually screened when passing through the sieve plates 321 arranged in sequence from large to small in terms of aperture and are discharged through the corresponding slag discharge pipes 325, thereby realizing the sorting operation of the ash-slag mixture. The setting of the sealing cover 323 avoids the ash material escaping into the interior of the housing 1 during the sorting process, causing the ash material to accumulate inside the housing 1 and affecting the operation of various components inside the housing 1. Further, since the dust discharge pipe 324, the slag discharge pipe 325, and the sealing cover 323 are all structures that can be freely stretched and bent, the sealing performance of the sorting barrel 32 during the movement process is ensured.

[0035] Combined with attached Figure 3 、attached Figure 5 、attached Figure 7 、attached Figure 8 、attached Figure 9 and attached Figure 10 As shown in the figure, the tremor mechanism includes a power rotating column 34 rotatably arranged at the upper end of the housing 1. A linkage sheave 341 and a power bevel gear 342 are respectively arranged at both ends of the power rotating column 34. The power bevel gear 342 meshes with the driving bevel gear 242. A support sheave 35 is rotatably arranged on one side of the housing 1 and is connected to the linkage sheave 341 through a belt. A support rotating arm 351 is arranged on the support sheave 35. A support slider 352 is rotatably arranged at one end of the support rotating arm 351. A sorting chute 311 that slidably cooperates with the support slider 352 is arranged at the upper end of the sorting carriage 31; A supporting slide bar 16 is provided on the inner side of the casing 1, and the supporting slide bar 16 is tilted. A sorting rack 33 is slidably provided on one side of the sorting slide 31, and a positioning slide sleeve 331 is rotatably provided on the sorting rack 33 and slidably sleeved on the supporting slide bar 16. A sorting tooth ring 322 meshing with the sorting rack 33 is provided on the outer side of the sorting barrel 32, and the sorting tooth ring 322 is a semicircular structure.

[0036] Working principle of the vibration mechanism: the driving bevel gear 242 rotates while driving the meshing power bevel gear 342 to rotate synchronously, the power rotating column 34 drives the linkage groove wheel 341 to rotate synchronously, the linkage groove wheel 341 drives the supporting groove wheel 35 to rotate through the belt, the supporting rotating arm 351 drives the supporting slider 352 to rotate synchronously, and the sorting chute 311 and the sorting slider 31 are moved up and down synchronously under the combined action of the sliding cooperation of the sorting chute 311 that slides with the supporting slider 352 and the sliding limit of the supporting chute 15 on the sorting slide 31. Reciprocating motion, during this process, the sorting slide 31 drives the sorting rack 33 to synchronously reciprocate up and down, and the positioning sleeve 331 slides along the supporting slide bar 16 synchronously. Since the supporting slide bar 16 is inclined, the positioning sleeve 331 can drive the sorting rack 33 to reciprocate linearly during the up and down reciprocating sliding process. Further, the sorting rack 33 drives the sorting barrel 32 to reciprocate in cooperation with the sorting tooth ring 322 meshing with it. The above two motion trajectories are combined, and the sorting barrel 32 reciprocates while performing up and down reciprocating motion; When the sorting barrel 32 is performing up and down reciprocating motion and reciprocating rotation at the same time, the slag is subjected to the action of multiple directional forces, so that the mutual squeezing and dislocation between the slag layers are more intense, thereby enhancing the stratification effect. At the same time, the up and down reciprocating motion gives the slag more opportunities to move perpendicular to the screen surface, thereby increasing the probability that the slag contacts and passes through the screen holes. The reciprocating rotation allows the slag to continuously change its position and movement direction on the screen surface, thereby avoiding the slag moving in only a single direction and resulting in low utilization rate of some screen holes. More slag that meets the requirements of the screen holes can be screened, thereby improving screening efficiency and accuracy. Furthermore, through this composite motion mode, the slag can be better turned, pushed and screened, and is suitable for slag in different forms such as block, granular or flaky, with stronger adaptability. Furthermore, since its motion frequency and amplitude are relatively easier to adjust and control, appropriate motion parameters can be selected according to the structural characteristics of the equipment and the characteristics of the slag, to avoid the resonance frequency of the equipment, reduce damage to the equipment caused by resonance, and extend the service life of the equipment.

[0037] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 8 , Attachment Figure 11 , Attachment Figure 12 and attached Figure 13As shown in the figure, the dust collection mechanism 4 includes a dust collection box 41 connected to the lower end of the housing 1. One side of the dust collection box 41 is connected to a dust collection chamber 412. The lower end of the dust collection chamber 412 is connected to a cleaning pipe, and a valve is provided on the cleaning pipe. A filter plate 413 is provided in the dust collection box 41, and the dust collection chamber 412 is located on one side of the filter plate 413. A negative pressure pump 411 is connected to the other side of the dust collection box 41 located on the other side of the filter plate 413. A cleaning mechanism for cleaning the filter plate 413 is provided on the other side of the dust collection box 41 located on the other side of the filter plate 413. The cleaning mechanism includes a cleaning slide rod 421 slidably provided on the housing 1. A cleaning brush 42 cooperating with the filter plate 413 is provided at the lower end of the cleaning slide rod 421. A cleaning connecting plate 422 is provided on the cleaning slide rod 421. A cleaning spring 423 connected to the housing 1 is provided on the cleaning connecting plate 422. A cleaning top rod 424 that movably abuts against the sorting slide frame 31 is provided on the cleaning slide rod 421.

[0038] Working principle of the dust collection mechanism 4: During the long-term use of the device of the present invention, due to reasons such as material aging, it is inevitable that ash and dust will escape into the housing 1. At this time, the negative pressure pump 411 keeps the inside of the housing 1 and the dust collection box 41 in a negative pressure state when it is in the starting state. The airflow carries ash and dust and contacts the filter plate 413 and is filtered by the filter plate 413. The ash and dust accumulate on the side of the filter plate 413 away from the negative pressure pump 411. During this process, since the sorting slide frame 31 moves up and down reciprocally, the sorting slide frame 31 will drive the cleaning connecting plate 422, the cleaning slide rod 421, and the cleaning brush 42 to move synchronously through the cleaning top rod 424. With the cooperation of the cleaning spring 423, the cleaning brush 42 moves up and down reciprocally synchronously, so as to realize the cleaning operation of the filter plate 413, ensure the efficient filtering effect of the filter plate 413. Further, the setting of the dust collection chamber 412 prevents ash and dust from accumulating at the lower end of the filter plate 413, further improving the smoothness of the airflow passing through. Through the linkage effect, there is no need to separately set a power component in the housing 1 to clean the filter plate 413, reducing the frequency and difficulty of maintenance.

[0039] When the present invention is specifically implemented, first, the ash discharge pipe 324 and multiple slag discharge pipes 325 are respectively connected to an external ash receiving mechanism and multiple external slag receiving mechanisms to complete the preparation work before using the device of the present invention; After that, start the drive motor 243 and the negative pressure pump 411 to check the device of the present invention before operation. After the inspection is completed, the sorting operation can be carried out; Then, the ash and slag mixture generated during the electrolytic aluminum processing is added into the housing 1 through the feed pipe 11. The drive motor 243 drives the grinding disk 21 to rotate. With the cooperation of the grinding convex columns 14, the slag is crushed and then the slag enters the aggregate hopper 12 under the action of gravity. During this process, since the ash is relatively fine, it directly falls into the aggregate hopper 12 under the action of gravity; Next, while the sorting barrel 32 moves up and down reciprocally, it also rotates reciprocally, and multiple sieve plates 321 move synchronously. During this process, since the diameter of the ash material is smaller than the aperture of the sieve plates 321, the ash material will directly fall through the multiple sieve plates 321 under the action of gravity and enter the bottom of the sorting barrel 32 and flow out through the ash discharge pipe 324. Different-sized slag materials are gradually screened when passing through the sieve plates 321 with apertures arranged from large to small in sequence and are discharged through the corresponding slag discharge pipes 325, realizing the sorting operation of the ash-slag mixture. During this process, the air flow carries the ash material and dust and contacts the filter plate 413 and is filtered by the filter plate 413. The ash material and dust accumulate on the side of the filter plate 413 away from the negative pressure pump 411. The cleaning brush 42 moves up and down reciprocally driven by the sorting carriage 31, realizing the cleaning operation of the filter plate 413.
