Description

Technical Field

[0001] The present invention relates to the technical field of aluminum slag processing, in particular to a salt slag press. Background Art

[0002] During the aluminum smelting and processing process, aluminum slag is produced in large quantities as an inevitable by-product. It is mainly composed of metallic aluminum, aluminum oxide, salt impurities, and small amounts of other components. Aluminum slag contains a certain amount of recyclable metallic aluminum, so it needs to be retained for recycling. However, after the hot aluminum slag is stored in the slag barrel, it will naturally cool, and a large amount of metal will oxidize and deteriorate, resulting in a waste of resources. Therefore, aluminum slag pressing applies external pressure to separate the residual liquid aluminum metal and some extrudable components from the solid slag. At the same time, the aluminum slag is pressed and cooled to form a slag cake, reducing the contact area with air and minimizing the burn-off of aluminum in the aluminum slag.

[0003] In the aforementioned prior art, when squeezing salt-containing aluminum slag, an aluminum slag box is usually set up, and then the salt-containing aluminum slag is stored, and then squeezed from top to bottom by a pressing head; but after the squeezing is completed, a large amount of aluminum slag impurities will inevitably adhere to the pressing head and the aluminum slag box, forming an aluminum slag layer and adhering to the pressing head and the aluminum slag box; such long-term squeezing will cause the aluminum slag layer to accumulate, and eventually affect the normal squeezing of the salt-containing aluminum slag.

[0037] In which, the pressing head 2 is arranged inside the supporting shell 1, the aluminum slag box 3 is placed below the pressing head 2, the pressing head 2 and the aluminum slag box 3 are adapted to each other, the arc slide rail 4 is arranged between the pressing head 2 and the aluminum slag box 3, the movable inner shell 5 is slidingly connected to the arc slide rail 4, the rotating outer shell 6 is sleeved on the outside of the movable inner shell 5, and a plurality of the knocking blocks 7, the scraper 8 and the cleaning brush 9 are sequentially arranged above the rotating outer shell 6. By arranging the movable inner shell 5 on the arc-shaped slide rail 4, the movable inner shell 5 drives the knocking block 7, the scraper 8 and the cleaning brush 9 to clean the pressing head 2 in sequence. During cleaning, the knocking block 7 first knocks the attached aluminum slag layer to make it initially fall off or loosen, and then relies on the scraper 8 to scrape it off, and finally relies on the cleaning brush 9 to rotate and sweep away small aluminum slag to carry out the finishing work. After cleaning the pressing head 2, the rotating outer shell 6 is flipped and aligned with the aluminum slag box 3, and then the above operation is repeated to clean the inner wall of the aluminum slag box 3.

[0038] Secondly, the cleaning moving unit is arranged inside the supporting shell 1; the two transverse moving parts 10 are arranged in sequence below the aluminum slag box 3, and the output ends of the two transverse moving parts 10 are respectively fixedly connected to the corresponding cleaning lifting parts 11, and the output ends of the cleaning lifting parts 11 are fixedly connected to the corresponding longitudinal parts 12, and the longitudinal parts 12 are symmetrically arranged between the pressing head 2 and the aluminum slag box 3, and the output ends of the two longitudinal parts 12 are respectively fixedly connected to the two ends of the arc slide rail 4. The transverse moving parts 10 and the longitudinal parts 12 are both electric slide rails, and the cleaning lifting part 11 is a self-locking cylinder; when the transverse moving part 10 is started, it can drive the arc-shaped moving mechanism to move laterally, and then move the knocking block 7, the scraper 8 and the cleaning brush 9 between the pressing head 2 and the aluminum slag box 3 for cleaning. During cleaning, the cleaning lifting part 11 can be started to make the knocking block 7, the scraper 8 and the cleaning brush 9 close to the pressing head 2 or the aluminum slag box 3; the longitudinal part 12 can also be started to adjust its position longitudinally during cleaning to clean different areas of the pressing head 2 or the aluminum slag box 3.

[0039] At the same time, the arc-shaped slider 13 is slidably connected to the arc-shaped slide rail 4, and a plurality of the arc-shaped driving components 14 are sequentially arranged inside the movable inner shell 5. The output ends of the plurality of the arc-shaped driving components 14 are respectively fixedly connected to the corresponding arc-shaped driving wheels 15, and the arc-shaped driving wheels 15 are in contact with the arc-shaped slide rail 4. The arc-shaped driving component 14 is a motor. When the arc-shaped driving component 14 is started, it drives the arc-shaped driving wheel 15 to rotate, thereby driving the movable inner shell 5 and the arc-shaped slider 13 to slide on the arc-shaped slide rail 4, thereby causing the knocking block 7, the scraper 8, and the cleaning brush 9 to move in an arc shape, thereby cleaning the arc-shaped pressing head 2 and the aluminum slag box 3. The curvature of the arc-shaped slide rail 4 is in contact with the curvature of the inner wall of the pressing head 2 and the aluminum slag box 3, so that the knocking block 7, the scraper 8, and the cleaning brush 9 can better clean the aluminum slag layer.

[0040] In addition, the external rotary drive unit is provided on the rotating outer shell 6; the fixed outer shell 16 is fixedly connected to the movable inner shell 5 and is sleeved on the outside of the movable inner shell 5; the rotating outer shell 6 is rotatably connected to the fixed outer shell 16 and sleeved on the outer wall of the fixed outer shell 16; multiple external rotary drive mechanisms are sequentially provided inside the fixed outer shell 16; the inner gear ring 17 is provided on one side of the rotating outer shell 6; multiple stabilizing slide bars 18 are provided on the other side of the rotating outer shell 6; the fixed outer shell 16 has an annular groove 19, and the annular groove 19 is slidably connected to the multiple stabilizing slide bars 18; the cleaning drive mechanism is provided above the rotating outer shell 6. The fixed outer shell 16 supports the rotating outer shell 6; the external rotary drive mechanism is activated, driving the rotating outer shell 6 to rotate on the fixed outer shell 16; at the same time, the stabilizing slide bars 18 slide in the annular groove 19 to maintain stability; finally, the cleaning drive mechanism is activated, driving the knocking block 7, the scraper 8, and the cleaning brush 9 to clean the aluminum slag layer.

[0041] The external rotary drive component 20 is then disposed within the fixed housing 16. The output end of the external rotary drive component 20 is fixedly connected to the gear 21, which meshes with the inner gear ring 17. The external rotary drive component 20 is a self-locking motor. When the external rotary drive component 20 is activated, it drives the gear 21 to rotate, which cooperates with the inner gear ring 17, thereby driving the rotating housing 6 to rotate, thereby achieving the flipping of the knocking block 7, the scraper 8, and the cleaning brush 9, and aligning them with the aluminum slag box 3 below.

[0042] Again, the cleaning shell 22 is fixedly connected to the rotating shell 6 and is located above the rotating shell 6. The three cleaning telescopic parts 23 are sequentially arranged inside the cleaning shell 22. The cleaning rotating part 24, multiple knocking blocks 7 and the scraper 8 are respectively arranged at the output ends of the corresponding cleaning telescopic parts 23. The output end of the cleaning rotating part 24 is fixedly connected to the cleaning brush 9, and multiple nylon protective covers 25 are respectively mounted on the outside of the scraper 8 and multiple knocking blocks 7. The cleaning telescopic component 23 is a self-locking electric push rod, and the cleaning rotating component 24 is a motor; the cleaning telescopic component 23 is started to drive the knocking block 7, the scraper 8 and the cleaning brush 9 to move up so that they are in contact with the pressing head 2; the corresponding cleaning telescopic component 23 can be started separately. After the knocking block 7 knocks the one side area of ​​the pressing head 2, the longitudinal component 12 moves longitudinally to drive it to move to the other side area. At the same time, the knocked area is subsequently scraped by the scraper 8. After the scraper 8 is completed, it is cleaned by the cleaning brush 9, thereby taking over in sequence. The same area needs to be cleaned in sequence by the knocking block 7, the scraper 8 and the cleaning brush 9, thereby effectively cleaning the aluminum slag layer; in addition, the scraper 8 and the knocking block 7 are both made of metal, which can improve the knocking and scraping effect. At the same time, the outside is wrapped with the nylon protective cover 25, which can protect the pressing head 2 and the aluminum slag box 3 while ensuring the cleaning effect to avoid scratches.

[0043] In addition, the pressing unit is arranged inside the supporting shell 1; the pressing lifting component 26 and the two sealing cover lifting components 27 are all arranged inside the supporting shell 1, the output end of the pressing lifting component 26 is fixedly connected to the pressing head 2, and the output ends of the two sealing cover lifting components 27 are fixedly connected to the sealing cover 28, the collecting box 29 is placed below the aluminum slag box 3, the ejection mechanism is arranged below the aluminum slag box 3, the diversion mechanism is arranged on the aluminum slag box 3, and the cooling mechanism is arranged inside the pressing head 2. The pressing lifting component 26 and the sealing cover lifting component 27 are both self-locking cylinders; the pressing lifting component 26 is started to drive the pressing head 2 to move downward, thereby pressing the salt-containing aluminum slag. Before pressing, the sealing cover lifting component 27 is first started to drive the sealing cover 28 to wrap and seal the outside of the aluminum slag box 3. At this time, the pressing head 2 is completely moved downward into the aluminum slag box 3, thereby avoiding the overflow of part of the aluminum slag during pressing, resulting in waste of resources; at the same time, during the pressing process, a part of the liquid aluminum water will be squeezed out and flow through the guide mechanism to the collection box 29 below. During this process, the cooling mechanism maintains the cooling of the pressing head 2, so that the remaining hot aluminum slag and aluminum are squeezed and cooled into slag cakes, which are then taken out by the ejection mechanism and enter the rotary furnace or similar equipment for secondary recovery.

[0044] Thus, the aluminum slag box 3 has a guide channel 34, and the coarse filter plate 30 and the fine filter plate 32 are both disposed within the guide channel 34. The coarse filter plate 30 is disposed above the fine filter plate 32 via a plurality of connecting blocks 31, and the fine filter plate 32 is connected to the bottom of the aluminum slag box 3 via a plurality of mounting blocks 33. The coarse filter plate 30 and the fine filter plate 32 are supported by the connecting blocks 31 to prevent damage caused by excessive pressing pressure. The fine filter plate 32 is fixed to the bottom of the aluminum slag box 3 via the mounting blocks 33. At the same time, before entering the aluminum slag box 3, the aluminum slag needs to be pre-processed and crushed to control its particle size to 10-50 mm, ensuring that the particle size entering the press is much larger than the pore size of the coarse filter plate 30 (2-3 mm). The pore size of the fine filter plate 32 is 0.5-1.0 mm. Thus, through two layers of filtration, fine particles can be separated and prevented from entering the collection box 29.

[0045] Furthermore, the pressing head 2 has a cooling trough 40, the cooling water tank 35 is arranged inside the cooling trough 40, the pump body 36 and the cooler 37 are arranged on the inner top wall of the cooling trough 40 in sequence, the water inlet end of the cooler 37 is connected to the water outlet end of the pump body 36, the water inlet end of the pump body 36 and the water outlet end of the cooler 37 are both connected to the cooling water tank 35, a plurality of fans 38 are arranged on both sides of the cooling trough 40 in sequence, and one end of a plurality of heat sinks 39 passes through the cooling water tank 35 in sequence and is located inside the cooling water tank 35. The cooling water tank 35 is used to store cooling water. The water is pumped into the refrigerator 37 through the pump body 36 to cool down, and then flows back to the cooling water tank 35. Since the cooling water tank 35 is in contact with the inner wall of the cooling groove 40 of the pressing head 2, the pressing head 2 can be effectively cooled, thereby realizing the cooling of the aluminum slag. The hot aluminum slag is squeezed between the pressing head 2 and the aluminum slag box 3 to form a nearly closed cavity, which minimizes the contact area and time between the hot aluminum slag and the air, thereby reducing the burning of aluminum in the hot aluminum slag. In addition, the fan 38 can also be started to blow external air into the cold air groove, through or to cool the heat sink 39, thereby further reducing the temperature of the cooling water.

[0046] Finally, the plurality of push-up support rods 41 are all slidably connected to the coarse filter plate 30 and the fine filter plate 32, one end of each of the push-up support rods 41 is fixedly connected to one end of the corresponding connecting plate 42, and the plurality of push-up drive components 43 are sequentially arranged below the aluminum slag box 3, and the output ends of each of the push-up drive components 43 are fixedly connected to the other end of the corresponding connecting plate 42. The push-up support rods 41 are located between the coarse filter plate 30 and the fine filter plate 32. When squeezing is completed, the push-up drive components 43 are activated, and the connection with the connecting plate 42 is relied upon to drive the push-up support rods 41 upward, thereby pushing the slag cake out of the aluminum slag box 3, so as to prevent the slag cake from being too tightly attached to the aluminum slag box 3 after squeezing is completed, making it impossible to remove it.

[0047] When using a salt slag press of this embodiment, the movable inner shell 5 is arranged on the arc slide rail 4, and the knocking block 7, the scraper 8 and the cleaning brush 9 are driven by the movable inner shell 5 to clean the pressing head 2 in sequence. During cleaning, the knocking block 7 first knocks the attached aluminum slag layer to cause it to initially fall off or loosen, and then the scraper 8 is used to scrape it off, and finally the cleaning brush 9 is used to rotate and sweep away small aluminum slag to carry out the finishing work. After cleaning the pressing head 2, the rotating outer shell 6 is turned over and aimed at the aluminum slag box 3, and then the above operation is repeated to clean the inner wall of the aluminum slag box 3;

[0048] Through the above-mentioned structural setting, the pressing head 2 and the aluminum slag box 3 after squeezing the aluminum slag can be comprehensively and effectively cleaned, reducing the adhesion of the aluminum slag layer, avoiding the accumulation of the aluminum slag layer caused by long-term use, and improving the service life of the salt slag press. In addition, by cleaning up the aluminum slag layer, the weight of the pressing head 2 can also be reduced, so that it can improve the squeezing efficiency and squeezing quality.
