Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid conveying technology, specifically a flow channel system for conveying aluminum liquid. Background Technology

[0002] In the aluminum alloy melting and casting process, the molten aluminum needs to be transferred to the holding furnace or casting process through the trough system in order to produce various aluminum alloy products.

[0003] Most flow channel systems are precast in sections and assembled on-site before being put into use. The sectioned structure of the flow channel requires high assembly precision. If the operation is not proper, problems such as steps, misalignment, and poor sealing between the flow channel sections can easily occur. Furthermore, the existing aluminum liquid flow channels have large splicing gaps, which cause the aluminum liquid to flow out from the gaps when it flows through the flow channel. After solidification, the pressure can cause the flow channel to break, which seriously affects the performance of the flow channel.

[0004] During the aluminum molten material transport process, the aluminum molten material comes into contact with air and undergoes an oxidation reaction, generating impurities such as aluminum oxide. Some existing flow channel systems may not have a structure for cleaning impurities. After long-term use, impurities may accumulate in the flow channel, affecting the quality of the aluminum molten material and the normal use of the flow channel. Existing cleaning methods often require manual cleaning, which is troublesome and time-consuming. The high labor intensity and difficulty of cleaning affect the efficiency of flow channel maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a flow channel system for conveying molten aluminum, so as to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A trough system for conveying molten aluminum includes trough prefabricated components, a seepage-proof layer, a heat insulation layer, a steel structure, a filtration mechanism, and a cleaning mechanism. Several trough prefabricated components are provided, two seepage-proof layers are provided, several trough prefabricated components and two seepage-proof layers are fixedly connected, the heat insulation layer and two seepage-proof layers are fixedly connected, the heat insulation layer and several trough prefabricated components are fixedly connected, the steel structure and the heat insulation layer are fixedly connected, the filtration mechanism and the cleaning mechanism are fixedly connected, and the cleaning mechanism and the steel structure are fixedly connected.

[0008] Several prefabricated flow channels are connected along the conveying direction to form a complete conveying route. The prefabricated flow channels are positioned on both sides by anti-seepage layers to prevent displacement due to the force of molten aluminum during operation. An insulation layer is provided, which wraps around the prefabricated flow channels and the anti-seepage layer, to reduce heat loss during long-distance transport of molten aluminum and prevent it from cooling and solidifying during transport. At the same time, it prevents the outer shell of the steel structure from deforming due to heat. A filtration mechanism is installed to filter impurities in the molten aluminum, and a cleaning mechanism cleans the inner wall of the flow channel of the prefabricated flow channels, thereby ensuring the quality of the molten aluminum.

[0009] Furthermore, the precast flow channel is provided with a boss and a groove, and the boss and the groove are fitted together.

[0010] By incorporating bosses and grooves that cooperate with each other, the two end faces of the prefabricated flow channel segments are connected by the bosses and grooves, enabling rapid installation and positioning of the segments. When a single segment is damaged, the concave-convex structure facilitates quick replacement. Simultaneously, the cross-section of the prefabricated flow channel is pressed tightly against the splice seam by its own weight, thus solving the problem of easy seepage of molten aluminum when flowing through the splice seam.

[0011] Furthermore, the insulation layer material is aluminum silicate fiberboard.

[0012] By using aluminum silicate fiberboard as the insulation material, heat loss is reduced during long-distance transport of molten aluminum, while also preventing the steel structure's outer shell from deforming due to heat.

[0013] Furthermore, the cleaning mechanism includes a fixed plate, a mounting plate, a primary motor, a rotating shaft, sprockets, chains, scrapers, and a control unit. There are four fixed plates, all fixedly connected to a steel structure. There are also four mounting plates, each slidably connected to one of the four fixed plates. The primary motor is fixedly connected to one mounting plate, and its output end is fixedly connected to the rotating shaft. There are eight sprockets and four rotating shafts, each connected to one of the four rotating shafts. There are two chains that mesh with the sprockets. Several scrapers are provided, with both ends fixedly connected to the two chains. The control unit is fixedly connected to both the fixed and mounting plates.

[0014] The cleaning mechanism is fixedly connected to the steel structure by four fixed plates, ensuring its stable position within the entire flow channel system. The four fixed plates and four mounting plates are slidably connected, allowing the mounting plates to move on the fixed plates. The control unit controls the up-and-down position of the mounting plates, enabling the rotating shaft, sprockets, chains, and scrapers to move above the flow channel preform during aluminum molten material transport, avoiding interference with the transport process. A motor drives one of the rotating shafts, causing the sprockets to rotate. Two chains are respectively mounted on four sprockets on the same side, rotating in the same direction. Several scrapers are fixed at both ends to the two chains. As the chains rotate cyclically, the scrapers move accordingly, moving along the inner wall of the flow channel of the flow channel preform. This removes alumina particles, dust, or other impurities adhering to the inner wall, cleaning the inner wall of the flow channel and ensuring the quality of the molten aluminum.

[0015] Furthermore, the control unit includes a second motor, a fixed block, a lead screw, and a nut seat. The second motor is fixedly connected to the fixed plate, the fixed block is fixedly connected to the fixed plate, the output end of the second motor is fixedly connected to the lead screw, the lead screw is rotatably connected to the fixed block, the nut seat is threadedly connected to the lead screw, and the nut seat is fixedly connected to the mounting plate.

[0016] The output end of motor No. 2 is fixedly connected to the lead screw, and the lead screw is rotatably connected to the fixing block, so that both ends of the lead screw are fixed, thereby driving motor No. 2 to drive the lead screw to rotate along its own axis. The lead screw is threadedly connected to the nut seat, so that the nut seat moves with the rotation of the lead screw. The nut seat is fixedly connected to the mounting plate, thereby driving the mounting plate to move up and down.

[0017] Furthermore, the filtration mechanism includes a connecting plate, a filter plate, and a locking block. The filter plate and the connecting plate are fixedly connected, the locking block and the connecting plate are fixedly connected, the fixing block is provided with a locking groove, and the locking block and the locking groove are fastened together.

[0018] By setting a locking block on the connecting plate, the locking block can be inserted into the slot of the fixing block to securely connect the connecting plate and the fixing block. This allows workers to easily insert the connecting plate into the fixing block to complete the installation. The filter plate and the connecting plate are fixedly connected, which facilitates the replacement of the filter plate and reduces the difficulty and time cost of maintenance.

[0019] Furthermore, the scraper has an inclined surface, and the angle between the inclined surface and the bottom surface is an acute angle.

[0020] The scraper has an inclined surface with an acute angle between the inclined surface and the bottom surface. When the scraper moves along the inner wall of the flow channel of the precast flow channel, the inclined surface can more effectively scrape off impurities. At the same time, the acute angle between the inclined surface and the bottom surface reduces the resistance to impurities when the inclined surface comes into contact with them, allowing the scraper to cut into and push the impurities more smoothly.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The two end faces of the prefabricated flow channel segments adopt groove and boss structures respectively. The groove and boss are assembled to achieve quick installation and positioning of the flow channel segments. When a single segment is damaged, the groove and boss structure can be easily replaced. The cross section of the prefabricated flow channel segments forms a boss and sealing groove structure through the groove and boss structure. This allows the flow channel to use its own weight to press the splice seam, thereby solving the problem of easy seepage of aluminum liquid when it flows through the splice seam.

[0023] 2. By setting anti-seepage layers on both sides of the precast flow channel, the precast flow channel is positioned on both sides after installation, preventing the precast flow channel from shifting during the operation of the flow channel system. This avoids gaps or gaps in the originally tightly connected precast flow channel, thus effectively preventing the leakage of molten aluminum.

[0024] 3. By using aluminum silicate fiberboard as the insulation material in the insulation layer, the insulation performance is excellent, thereby reducing heat loss of molten aluminum during long-distance transportation and preventing the steel structure shell from deforming due to heat.

[0025] 4. By setting a locking block on the connecting plate, the locking block can be inserted into the fixing block to securely connect the connecting plate and the fixing block. This allows workers to easily insert the connecting plate into the fixing block to complete the installation. The filter plate and the connecting plate are fixedly connected, which facilitates the replacement of the filter plate and reduces the difficulty and time cost of maintenance.

[0026] 5. The control unit enables the rotating shaft, sprocket, chain, and scraper to move above the flow channel preform during aluminum molten material conveying, thus avoiding interference with the aluminum molten material conveying. The sprocket is driven to rotate by motor number one, causing several scrapers fixed on two chains to move with the cyclic rotation of the two chains, thereby achieving automatic cleaning of the inner wall of the flow channel of the flow channel preform.

[0034] 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.

[0035] Example: Figure 1 and Figure 3 As shown, this utility model provides a technical solution for a trough system for conveying molten aluminum. The trough system includes a trough prefabricated component 1, a seepage-proof layer 2, a heat insulation layer 3, a steel structure 4, a filtration mechanism 5, and a cleaning mechanism 6. Several trough prefabricated components 1 are provided, and two seepage-proof layers 2 are provided. Several trough prefabricated components 1 and two seepage-proof layers 2 are fixedly connected. The heat insulation layer 3 and two seepage-proof layers 2 are fixedly connected. The heat insulation layer 3 and several trough prefabricated components 1 are fixedly connected. The steel structure 4 and the heat insulation layer 3 are fixedly connected. The filtration mechanism 5 and the cleaning mechanism 6 are fixedly connected. The cleaning mechanism 6 and the steel structure 4 are fixedly connected.

[0036] Several prefabricated flow channels 1 are connected along the conveying direction to form a complete conveying route. The prefabricated flow channels 1 are positioned on both sides by the anti-seepage layers 2 to prevent displacement of the prefabricated flow channels 1 due to the force of the molten aluminum during operation. The presence of an insulation layer 3, which wraps around the prefabricated flow channels 1 and the anti-seepage layer 2, reduces heat loss during long-distance conveying of the molten aluminum, preventing it from cooling and solidifying during transport and preventing the outer shell of the steel structure 4 from deforming due to heat. The presence of a filtration mechanism 5 filters impurities in the molten aluminum, and the presence of a cleaning mechanism 6 cleans the inner wall of the flow channel of the prefabricated flow channels 1, thereby ensuring the quality of the molten aluminum.

[0037] like Figure 1 and Figure 2As shown, the precast part 1 of the flow channel is provided with a boss 11 and a groove 12, and the boss 11 and the groove 12 are fitted together.

[0038] By providing a boss 11 and a groove 12, and having the boss 11 and groove 12 cooperate with each other, the two end faces of the segment of the flow channel prefabricated part 1 are connected by the boss 11 and groove 12, thereby realizing the rapid installation and positioning of the segment of the flow channel prefabricated part 1. When a single segment is damaged, the concave and convex structure can be easily and quickly replaced. At the same time, the cross section of the flow channel prefabricated part 1 is pressed tightly by its own weight to the splice seam, thereby solving the problem of easy seepage of aluminum liquid when it flows through the splice seam.

[0039] like Figure 3 As shown, the insulation layer 3 is made of aluminum silicate fiberboard.

[0040] By using aluminum silicate fiberboard as the material for insulation layer 3, heat loss is reduced during long-distance transport of molten aluminum, while also preventing the outer shell of steel structure 4 from deforming due to heat.

[0041] like Figures 3-5 As shown, the cleaning mechanism 6 includes a fixed plate 61, a mounting plate 62, a primary motor 63, a rotating shaft 64, sprockets 65, chains 66, scrapers 67, and a control unit 68. There are four fixed plates 61, which are fixedly connected to the steel structure 4. There are four mounting plates 62, which are slidably connected to the four fixed plates 61 respectively. The primary motor 63 is fixedly connected to one mounting plate 62, and the output end of the primary motor 63 is fixedly connected to the rotating shaft 64. There are eight sprockets 65 and four rotating shafts 64, which are connected to the four rotating shafts 64 respectively. There are two chains 66, which mesh with the sprockets 65. There are several scrapers 67, whose ends are fixedly connected to the two chains 66. The control unit 68 is fixedly connected to both the fixed plate 61 and the mounting plate 62.

[0042] The cleaning mechanism 6 is fixedly connected to the steel structure 4 by four fixed plates 61, ensuring the stability of its position in the entire flow channel system. The four fixed plates 61 and four mounting plates 62 are slidably connected, allowing the mounting plates 62 to move on the fixed plates 61. The control unit 68 controls the up-and-down position of the mounting plates 62, enabling the rotating shaft 64, sprocket 65, chain 66, and scraper 67 to move above the flow channel prefabricated component 1 during aluminum molten material transport, avoiding interference with the transport. One of the rotating shafts 64 is driven to rotate by a motor 63, causing the sprocket 65 to... The two chains 66 are respectively mounted on four sprockets 65 on the same side, so that the chains 66 rotate in the direction of rotation of the sprockets 65. Several scrapers 67 are fixed to the two chains 66 at both ends. As the two chains 66 rotate in a cycle, the scrapers 67 also move. The scrapers 67 move along the inner wall of the flow channel of the flow channel preform 1, thereby scraping off some alumina particles, dust or other impurities attached to the inner wall of the flow channel of the flow channel preform 1, cleaning the inner wall of the flow channel of the flow channel preform 1, and thus ensuring the quality of the aluminum liquid.

[0043] like Figure 3 As shown, the control unit 68 includes a second motor 681, a fixing block 682, a lead screw 683, and a nut seat 684. The second motor 681 is fixedly connected to the fixing plate 61, the fixing block 682 is fixedly connected to the fixing plate 61, the output end of the second motor 681 is fixedly connected to the lead screw 683, the lead screw 683 is rotatably connected to the fixing block 682, the nut seat 684 is threadedly connected to the lead screw 683, and the nut seat 684 is fixedly connected to the mounting plate 62.

[0044] The output end of the second motor 681 is fixedly connected to the lead screw 683, and the lead screw 683 is rotatably connected to the fixing block 682, so that both ends of the lead screw 683 are fixed, thereby driving the second motor 681 to drive the lead screw 683 to rotate along its own axis. The nut seat 684 is threadedly connected to the lead screw 683, so that the nut seat 684 moves with the rotation of the lead screw 683. The nut seat 684 is fixedly connected to the mounting plate 62, thereby driving the mounting plate 62 to move up and down.

[0045] like Figure 3 and Figure 5 As shown, the filter mechanism 5 includes a connecting plate 51, a filter plate 52, and a locking block 53. The filter plate 52 and the connecting plate 51 are fixedly connected, the locking block 53 and the connecting plate 51 are fixedly connected, and the fixing block 682 is provided with a locking groove. The locking block 53 and the locking groove are fastened together.

[0046] By setting a locking block 53 on the connecting plate 51, the locking block 53 is locked into the slot of the fixing block 682, so that the connecting plate 51 and the fixing block 682 are securely connected. This allows workers to easily insert the connecting plate 51 into the fixing block 682 to complete the installation. The filter plate 52 and the connecting plate 51 are fixedly connected, which facilitates the replacement of the filter plate 52 and reduces the difficulty and time cost of maintenance.

[0047] like Figure 6 As shown, the scraper 67 has an inclined surface 671, and the angle between the inclined surface 671 and the bottom surface is an acute angle.

[0048] The scraper 67 is provided with an inclined surface 671, and the angle between the inclined surface 671 and the bottom surface is an acute angle. When the scraper 67 moves along the inner wall of the flow channel of the flow channel preform 1, the inclined surface 671 can more effectively scrape off impurities. At the same time, the angle between the inclined surface 671 and the bottom surface is an acute angle, which reduces the resistance of the inclined surface 671 to impurities when it comes into contact with them, so that the scraper 67 can cut into and push the impurities more smoothly.

[0049] Working principle: With bosses 11 and grooves 12 that cooperate with each other, the two end faces of the segmented flow channel prefabricated component 1 are aligned, enabling rapid installation and positioning of the segmented flow channel prefabricated component 1. Several flow channel prefabricated components 1 are connected along the conveying direction to form a complete conveying route. Motor 681 drives the lead screw 683 to rotate along its own axis, causing the nut seat 684 to move with the lead screw 683, thereby moving the mounting plate 62 up and down. This allows the scraper 67 to fit against the inner wall of the flow channel of the flow channel prefabricated component 1. Motor 1... Machine 63 drives one of the rotating shafts 64 to rotate, causing the sprocket 65 to rotate. Two chains 66 are respectively sleeved on the four sprockets 65 on the same side, so that the chains 66 rotate in the direction of rotation of the sprockets 65. Several scrapers 67 are fixed at both ends to the two chains 66. As the two chains 66 rotate in a cycle, the scrapers 67 also move. The scrapers 67 move along the inner wall of the flow channel of the flow channel preform 1, thereby scraping off some alumina particles, dust or other impurities attached to the inner wall of the flow channel of the flow channel preform 1, thus cleaning the inner wall of the flow channel of the flow channel preform 1.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
