Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, and in particular to a rare earth aluminum alloy degassing box. Background Technology

[0002] The production process of aluminum alloys involves mixing and heating various elemental metals to melt them into a liquid state, followed by a series of processes to form the alloy. The degassing process mainly aims to remove gaseous and oxide impurities from the liquid metal.

[0003] A search revealed a prior art degassing and stirring device for an aluminum alloy foil production line (publication number: CN109576512B), comprising a stirring box. The stirring box is divided into a left side chamber, a middle chamber, and a right side chamber from left to right by two partitions. The upper part of the left side chamber is connected to the upper part of the middle chamber, the lower part of the left side chamber is connected to the lower part of the middle chamber, the upper part of the middle chamber is connected to the upper part of the right side chamber, and the lower part of the middle chamber is connected to the lower part of the right side chamber. The lower part of the left side chamber has a discharge port, and the upper part of the right side chamber has a feed port. The middle chamber has a horizontally arranged lifting plate, and a lifting rod is connected to the middle of the lifting plate. The lifting rod is driven to rise and fall by a cylinder installed outside the stirring box. The front and rear sides of the lifting plate are close to the front and rear inner walls of the stirring box, respectively. The left and right sides of the lifting plate are close to the two partitions, respectively. The interior of each partition has a vent pipe, and the bottom of each partition has an air outlet connected to the vent pipe. The vent pipe extends out of the stirring box.

[0004] Existing technology mainly discharges materials through pipes at the bottom of the container. Since a certain amount of slag will form on the surface after the material is melted, the bottom discharge method requires manual removal of the surface slag. For large-capacity containers, the safety of slag removal is difficult to guarantee. In addition, the workload of slag removal is large. If slag can be removed during the material discharge process, on the one hand, production efficiency can be improved, and on the other hand, the safety of production can be guaranteed.

[0005] Therefore, we propose a rare earth aluminum alloy degassing box. Utility Model Content

[0006] This utility model mainly solves the technical problem of the large workload of removing floating slag from pipeline discharge, and provides a rare earth aluminum alloy degassing box.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a rare earth aluminum alloy degassing box, comprising:

[0008] The lower housing and the upper cover together form a sealed housing;

[0009] Support components are located on the sides of the lower housing and the upper cover to enable the lower housing to flip and the upper cover to move.

[0010] An air extraction structure is located at the top of the upper cover to extract air from the chamber of the lower housing.

[0011] The unloading structure is located on one side of the lower box to guide the material discharged from the lower box. The unloading structure includes a secondary box, a discharge pipe and baffles. The secondary box is fixedly connected to the lower box. A discharge pipe is fixedly installed on each side of the secondary box. The discharge pipe is connected to a valve. Several baffles are detachably installed inside the secondary box. The multiple baffles form a sawtooth structure to disperse the material discharged from the lower box.

[0012] In a preferred embodiment of this utility model, the secondary housing is a rectangular housing with an open top, and the discharge pipe is fixedly installed on the side wall of the secondary housing near the bottom.

[0013] In a preferred embodiment of this utility model, the baffle is a rectangular plate, the baffle is the same length as the chamber of the sub-box, the baffle extends inclined towards the lower box, and there is a gap between two adjacent baffles for material to fall.

[0014] In a preferred embodiment of this utility model, the unloading structure further includes ribs and a support plate. The support plate is fixedly connected to the auxiliary box body, and the baffle is fixedly connected to the ribs. The ribs are supported and limited by the support plate.

[0015] In a preferred embodiment of this utility model, both the support plate and the rib are rectangular rods, the lower ends of the multiple baffles are fixedly connected to the top surface of the rib, the rib is placed on the top of the support plate, a support plate is provided on each of the two inner walls opposite to each other of the sub-box, and two ribs are provided below the baffle.

[0016] In a preferred embodiment of this utility model, the air extraction structure includes an air extraction box, an air extraction pipe, and a negative pressure pipe. The air extraction box is fixedly installed with the top cover, and two air extraction pipes are fixedly installed at the bottom of the air extraction box and connected to the air extraction box. The negative pressure pipe is fixedly connected to the top of the air extraction box.

[0017] As a preferred embodiment of the present invention, the air extraction structure further includes a first side plate and a second side plate. Two first side plates and a second side plate are fixedly installed inside the air extraction box. The two first side plates are arranged in an inward V-shape, and the two second side plates are arranged in an outward V-shape. The first side plate is located above the second side plate, and a gap is left between the first side plate and the second side plate. Two air extraction pipes are located below the two second side plates respectively.

[0018] In a preferred embodiment of this utility model, the support assembly includes a truss, a support base, and a hydraulic push rod. The truss is fixedly installed on the ground, the upper cover is fixedly installed on the output end of the truss, the support base is fixedly installed on the ground, the lower housing is rotatably connected to the support base, and the hydraulic push rod is rotatably connected to the ground via a base. The output shaft of the hydraulic push rod is rotatably connected to the outer wall of the lower housing.

[0019] This utility model provides a rare earth aluminum alloy degassing box. It has the following beneficial effects:

[0020] 1. This rare earth aluminum alloy degassing box features a secondary box installed at the discharge port of the lower box. When the lower box is tilted for unloading, the material is injected into the secondary box from the discharge port of the lower box. The fluid material is cut by a serrated structure formed by multiple baffles, suppressing the overall impact of the material on the bottom of the secondary box and preventing splashing, thus making unloading safer. Two discharge pipes are provided, one of which is used to discharge scum from the secondary box. In the initial stage of unloading, since the scum floats on the upper layer of the material, the scum is discharged into the secondary box first when the lower box is tilted. It can be discharged through one of the discharge pipes. Then, the valve of the scum discharge pipe is closed, and the valve of the other discharge pipe is opened. The material after being cut is discharged from the other discharge pipe, achieving preliminary scum removal during the discharge process.

[0021] 2. This rare earth aluminum alloy degassing box uses two ribs to install and fix multiple baffles into a whole. The ribs are placed on a support plate and lifted. The ribs and multiple baffles can be removed from the auxiliary box for cleaning by lifting the baffles, which facilitates later maintenance.

[0022] 3. This rare earth aluminum alloy degassing box connects a negative pressure pipe to an external exhaust fan. Specifically, after the negative pressure pipe is connected to the air intake of the exhaust fan through a pipeline, the exhaust pipe extracts the gas generated in the lower box and forms a certain negative pressure environment, which promotes the overflow of gas in the material and improves the exhaust effect.

[0023] 4. This rare-earth aluminum alloy degassing box, by setting multiple first and second side plates inside the suction box, uses the second side plates to block the upper port of the suction pipe. The rising gas will first impact the second side plates, preventing particulate matter mixed in the gas from being sucked into the fan. The first side plates further guide and deflect the gas, further reducing the probability of impurities carried by the gas rising straight up and being sucked into the fan, thus ensuring the stable operation of the suction structure.

[0024] 5. This rare earth aluminum alloy degassing box allows the upper cover to slide and rise via a two-axis truss, facilitating its transport to one side of the lower box. Simultaneously, it ensures the upper cover fits tightly against the top of the lower box to form a seal. The truss output shaft drives the lower box to rotate around a support base. A rotating shaft is fixedly installed on one side of the support base, and a bushing is fixedly installed on the side wall of the lower box. The rotating shaft and bushing are rotatably connected to achieve the rotational movement of the lower box. The rotatable lower box has higher discharge efficiency and facilitates slag removal. Compared to using a pipe installed at the bottom of the lower box for discharge, the rotatable discharge method is less prone to clogging. Attached Figure Description

[0032] A rare earth aluminum alloy degassing box, such as Figure 1 and Figure 2 As shown, it includes:

[0033] The lower box 10 and the upper cover 11 together form a sealed box.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the unloading structure is set on one side of the lower box 10 to guide the material discharged from the lower box 10. The unloading structure includes a secondary box 20, a discharge pipe 21, and baffles 22. The secondary box 20 is fixedly connected to the lower box 10. A discharge pipe 21 is fixedly installed on each side of the secondary box 20. The discharge pipe 21 is connected to a valve. Several baffles 22 are detachably installed inside the secondary box 20. The multiple baffles 22 form a sawtooth structure to disperse the material discharged from the lower box 10. The secondary box 20 is a rectangular box with an open top. The discharge pipe 21 is fixedly installed on the side wall of the secondary box 20 near the bottom. The baffles 22 are rectangular plates with the same length as the chamber of the secondary box 20. The baffles 22 extend inclined towards the lower box 10. There is a gap between two adjacent baffles 22 for material to fall.

[0035] In this scheme, by installing a secondary box 20 at the discharge port of the lower box 10, when the lower box 10 is tilted to unload, the material is injected into the secondary box 20 from the discharge port of the lower box 10. The fluid material is cut by the sawtooth structure formed by multiple baffles 22, which suppresses the material from splashing due to the overall impact on the bottom of the secondary box 20, making the unloading safer. Two discharge pipes 21 are set up. One discharge pipe 21 is used to discharge the scum in the secondary box 20. In the initial stage of unloading, since the scum floats on the upper layer of the material, when the lower box 10 is tilted, the scum is discharged into the secondary box 20 first. The scum can be discharged through one of the discharge pipes 21. Then the valve of the scum discharge pipe 21 is closed and the valve of the other discharge pipe 21 is opened. The material after being cut is discharged from the other discharge pipe 21. The initial scum removal is achieved in the discharge process.

[0036] like Figure 4 As shown, the unloading structure also includes ribs 23 and pallets 24. The pallets 24 are fixedly connected to the sub-box 20, and the baffles 22 are fixedly connected to the ribs 23. The ribs 23 are supported and limited by the pallets 24. Both the pallets 24 and the ribs 23 are rectangular rods. The lower ends of the multiple baffles 22 are fixedly connected to the top surface of the ribs 23. The ribs 23 are placed on the top of the pallets 24. One pallet 24 is provided on each of the two inner walls of the sub-box 20. Two ribs 23 are provided below the baffles 22.

[0037] In this solution, since scum easily forms scale on the baffle 22, multiple baffles 22 are installed and fixed together by two ribs 23. The ribs 23 are placed on the support plate 24 and lifted up. The ribs 23 and multiple baffles 22 can be removed from the sub-box 20 for cleaning by lifting the baffles 22, which facilitates later maintenance.

[0038] like Figure 1 and Figure 5 As shown, the air extraction structure is set on the top of the upper cover 11 for extracting air from the chamber of the lower box 10.

[0039] The air extraction structure includes an air intake box 30, an air extraction pipe 31, and a negative pressure pipe 32. The air intake box 30 is fixedly installed with the upper cover 11. Two air extraction pipes 31 are fixedly installed at the bottom of the air intake box 30 and are connected to the air intake box 30. The negative pressure pipe 32 is fixedly connected to the top of the air intake box 30. In this solution, by connecting the negative pressure pipe 32 to an external exhaust fan, specifically, after the negative pressure pipe 32 is connected to the air intake of the exhaust fan through a pipe, the air extraction pipe 31 extracts the gas generated in the lower box 10 and forms a certain negative pressure environment, which promotes the overflow of gas in the material and improves the exhaust effect.

[0040] like Figure 6As shown, the exhaust structure also includes a first side plate 33 and a second side plate 34. Two first side plates 33 and two second side plates 34 are fixedly installed inside the exhaust box 30. The two first side plates 33 are arranged inwards, and the two second side plates 34 are arranged outwards. The first side plate 33 is located above the second side plate 34, and there is a gap between the first side plate 33 and the second side plate 34. Two exhaust pipes 31 are located below the two second side plates 34 respectively. By setting multiple first side plates 33 and second side plates 34 inside the exhaust box 30, the upper port of the exhaust pipe 31 is blocked by the second side plate 34. The rising gas will first impact the second side plate 34 to prevent the gas from being sucked into the fan. The first side plate 33 guides and deflects the gas, further reducing the probability of the gas carrying impurities rising straight up and being sucked into the fan, thus ensuring the stable operation of the exhaust structure.

[0041] like Figure 1 and Figure 2 As shown, the support assembly is located on the side of the lower housing 10 and the upper cover 11 to enable the lower housing 10 to flip and the upper cover 11 to move.

[0042] The support assembly includes a truss 12, a support base 13, and a hydraulic push rod 14. The truss 12 is fixedly installed on the ground, the upper cover 11 is fixedly installed on the output end of the truss 12, the support base 13 is fixedly installed on the ground, the lower housing 10 is rotatably connected to the support base 13, and the hydraulic push rod 14 is rotatably connected to the ground via a base. The output shaft of the hydraulic push rod 14 is rotatably connected to the outer wall of the lower housing 10. A vibration motor can be installed at the bottom of the lower housing 10 to promote the overflow of gas from the material and to suppress material blockage and promote discharge. The two-axis truss 12 enables… The upper cover 11 can slide and lift, making it easy to transport the upper cover 11 to one side of the lower box 10. At the same time, it can ensure that the upper cover 11 can fit tightly against the top of the lower box 10 to form a seal. The lower box 10 is pushed to rotate around the support base 13 by the output shaft of the truss 12. A rotating shaft is fixedly installed on one side of the support base 13, and a bushing is fixedly installed on the side wall of the lower box 10. The rotating shaft and the bushing are rotatably connected to realize the rotation movement of the lower box 10. The rotatable lower box 10 has higher material discharge efficiency and can facilitate slag removal. Compared with the material discharge method using a pipe installed at the bottom of the lower box 10, the rotatable material discharge is less prone to blockage.

[0043] The working principle of this utility model is as follows: The hydraulic push rod 14 needs to be connected to a central pump station for use. The central pump station supplies oil to the hydraulic push rod 14. The exhaust fan and vibration motor are connected to the power supply and control switch. The valve can be a manually controlled valve or an electric valve. The specific types are not limited.

[0044] The truss 12 with two axes allows the upper cover 11 to slide and rise, facilitating its transport to one side of the lower housing 10. Simultaneously, it ensures the upper cover 11 fits tightly against the top of the lower housing 10 to form a seal. The output shaft of the truss 12 pushes the lower housing 10 to rotate around the support base 13. A rotating shaft is fixedly installed on one side of the support base 13, and a bushing is fixedly installed on the side wall of the lower housing 10. The rotating shaft and bushing are rotatably connected to achieve the rotational movement of the lower housing 10. The negative pressure pipe 32 is connected to an external exhaust fan. Specifically... After the negative pressure pipe 32 is connected to the air intake of the exhaust fan through a pipeline, the exhaust pipe 31 extracts the gas generated in the lower box 10 and forms a certain negative pressure environment, promoting the overflow of gas in the material. By setting multiple first side plates 33 and second side plates 34 in the suction box 30, the upper port of the exhaust pipe 31 is blocked by the second side plate 34. The rising gas will first impact the second side plate 34 to prevent the particulate matter mixed in the gas from being sucked into the fan. The gas is then guided back by the first side plate 33, further reducing the gas carryover. To reduce the probability of impurities rising linearly and being sucked into the fan, a secondary housing 20 is installed at the discharge port of the lower housing 10. When the lower housing 10 is tilted to unload, the material is injected into the secondary housing 20 from the discharge port of the lower housing 10. The serrated structure formed by multiple baffles 22 cuts the fluid material, suppressing the overall impact of the material on the bottom of the secondary housing 20 and preventing splashing, making unloading safer. Two discharge pipes 21 are set, one of which is used to discharge the scum in the secondary housing 20. In the initial stage of unloading, since the scum floats on the upper layer of the material, When the current box 10 is tilted, the first thing discharged into the secondary box 20 is scum. The scum can be discharged through one of the discharge pipes 21. Then, the valve of the discharge pipe 21 is closed and the valve of the other discharge pipe 21 is opened. The material after being cut is discharged from the other discharge pipe 21, thus achieving material discharge. Multiple baffles 22 are installed and fixed into a whole by two ribs 23. The ribs 23 are placed on the support plate 24 and lifted. The ribs 23 and multiple baffles 22 can be removed from the secondary box 20 for cleaning by lifting the baffles 22.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
