Description

Technical Field

[0001] This invention relates to a metal residue treatment system, and more particularly to a non-ferrous metal residue treatment system. Background Technology

[0002] In the non-ferrous metal smelting process, the generated residue needs to be treated. The treatment process usually involves transporting the residue to a cooling zone for cooling and then dumping it into a slag dumping area. Currently, there are two methods on the market for transporting the residue to the slow cooling zone and dumping the residue:

[0003] The first method uses a gantry crane hook, as shown in the attached image. Figure 1 As shown, using a gantry crane hook has the following disadvantages:

[0004] 1. During use, each gantry crane hook requires two operators, one of whom operates the gantry crane hook and the other is responsible for ground support and command. As production increases, more gantry crane hooks and corresponding personnel are needed, which leads to a significant increase in labor costs.

[0005] 2. The operation of gantry crane hooks carries high safety risks and poses potential safety hazards;

[0006] 3. The gantry crane hook operation method cannot achieve intelligent and unmanned operation, which will lead to reduced efficiency and increased costs;

[0007] 4. Gantry crane hooks require significant maintenance costs;

[0008] 5. Because the gantry crane hook operates outdoors, it is greatly affected by changes in external weather, which in turn affects the progress.

[0009] The second method involves using large-tonnage tanker trucks, as shown in the attached document. Figure 2 As shown, using large-tonnage tanker trucks has the following disadvantages:

[0010] 1. Because tank trucks waste a lot of space in necessary transport channels, turning channels, turns and U-turns, the number of slag bags available for tank trucks to discharge is greatly reduced.

[0011] 2. Each tanker truck requires one operator. As the output of residue increases, more tanker trucks will be needed, which in turn will require more personnel, greatly increasing the operating cost.

[0012] 3. The operation of tanker trucks carries high safety risks and poses potential safety hazards;

[0013] 4. The maintenance and upkeep costs of tank trucks are relatively high in the later stages, and the maintenance costs increase with the number of years of use.

[0014] 5. The operation of tanker trucks cannot achieve intelligent and unmanned operation, which will lead to reduced efficiency and increased costs;

[0015] 6. Tanker trucks are susceptible to the effects of external weather. Summary of the Invention

[0016] To address the problems in related technologies, this application provides a non-ferrous metal residue treatment system that solves the problems of a large number of operators, high safety risks, inability to achieve intelligent and unmanned management, high maintenance costs, susceptibility to weather conditions, and a small number of cooling slag bags discharged.

[0017] The technical solution is as follows:

[0018] A non-ferrous metal residue treatment system includes a first track group, on which a slag bag transport vehicle for transporting slag bags travels. A cooling station is located on one side of the first track group, and multiple first rotary worktables for adjusting the direction of the slag bag transport vehicle are provided on the first track group corresponding to the cooling station.

[0019] Its features include a conveyor rail assembly at the cooling station, with cooling areas formed on both sides of the conveyor rail assembly for placing slag bags. A slag bag handling vehicle travels on the conveyor rail assembly, and the slag bag handling vehicle is equipped with a bag-retrieving mechanism. When retrieving a slag bag, the bag-retrieving mechanism extends to remove the slag bag from the slag bag transport vehicle and places it on the slag bag handling vehicle. After the slag bag is placed, the bag-retrieving mechanism retracts, and the slag bag handling vehicle carries the slag bag in a straight line to the cooling area.

[0020] The bag-retrieving mechanism and the slag bag operating vehicle are rotated together. When the cooling operation is performed, the bag-retrieving mechanism rotates the slag bag by 90°, then extends to remove the slag bag from the slag bag operating vehicle and places it in the cooling area. After the slag bag is placed, the bag-retrieving mechanism retracts.

[0021] The cooling station has a slag dumping station on the side away from the first track group. When the slag dumping operation is performed, the slag bag operating vehicle travels in a straight line to the position of the cooled slag bag, the bag-retrieving mechanism rotates to face the slag bag, the bag-retrieving mechanism extends to remove the slag bag and place it on the slag bag operating vehicle, the slag bag operating vehicle carries the cooled slag bag in a straight line to the slag dumping station, the bag-retrieving mechanism rotates to face the slag dumping station, the bag-retrieving mechanism dumps the slag bag, after the slag dumping is completed, the bag-retrieving mechanism retrieves the empty slag bag and places the empty slag bag on the slag bag operating vehicle.

[0022] Through the above technical solution, by setting up the slag bag operating vehicle, after the bag-retrieving mechanism picks up the slag bag, it first places the slag bag on the top of the slag bag operating vehicle. After placement, the bag-retrieving mechanism is retracted, and the slag bag operating vehicle drives the bag-retrieving mechanism to travel in a straight line along the conveyor track group, transporting the slag bag to the designated position in the cooling area. After cooling, the slag bag is picked up by the slag bag operating vehicle and the slag is dumped. In this process, because the bag-retrieving mechanism and the slag bag operating vehicle are rotated together, the structure is simple and the operation is quick. This means that the slag bag transport vehicle does not need to set up a corresponding channel for turning or turning, which can effectively avoid occupying more cooling station area. The space saved can be used to discharge more slag bags, and the slag bags can be placed at any position in the cooling area, thereby increasing the number of slag bags discharged.

[0023] It can also achieve automated control of the slag bag handling vehicle remotely. The slag bag handling vehicle can automatically pick up, put down and flip the bag. This can eliminate the need for operators on each slag bag handling vehicle, thereby basically eliminating safety hazards in the slag handling process and ensuring safety. Moreover, as the number of slag bag handling vehicles increases, there is no need to increase the number of personnel to remotely operate and control the slag bag handling vehicles, thereby reducing the input of labor costs.

[0024] In addition, the maintenance cost of the slag bag handling vehicle is low, and the slag bag handling vehicle is not affected by external weather changes, which can reduce the investment cost.

[0025] Preferably, the front and rear ends of the slag bag operating vehicle are respectively provided with rail grabbers corresponding to the positions of the conveying track group, and the structure of each rail grabber is the same;

[0026] The rail grabber includes rail grabbing blocks symmetrically arranged on both sides of the rail and a push cylinder. Both rail grabbing blocks are rotated in conjunction with the slag bag operating vehicle. Each of the two rail grabbing blocks has a clamp on the side of the lower part that is close to each other. The thickness of each clamp is less than the groove width of the corresponding side groove of the rail.

[0027] The two rail grabbing blocks are connected by a return spring, and the return spring is located above the hinge point between the rail grabbing block and the slag bag operating car;

[0028] The push cylinder is fixedly installed on the slag bag operating vehicle. The piston rod of the push cylinder is connected to a support block. The support block is vertically arranged between the two rail grabbing blocks and above the rail. The support block and the two rail grabbing blocks are in sliding cooperation.

[0029] When the hydraulic cylinder pushes the support block downwards until the support block abuts against the rail, the two rail gripping blocks respectively abut against the bottom of the groove on the corresponding side of the rail, so that the rail gripper can withstand both pressure and tension.

[0030] Through the above technical solution, by setting up the rail grabber, when the bag-retrieving mechanism is at different angles or the slag bag is in different operating states, the pressure and tension at different positions in the rail grabber are constantly switching. When a rail grabber needs to withstand pressure, it pushes the hydraulic cylinder to drive the support block so that the support block abuts against the top of the rail, thereby transmitting the pressure to the rail. At this time, the two clamps of each rail grabber clamp the rail respectively, so that the slag bag operating vehicle can withstand the tension. Even if the clamps are under pressure and the two clamps move downwards respectively, because the thickness of the clamps is less than the groove width of the groove on the side of the rail, the clamps can move within the groove, thereby avoiding the tension being affected, thus effectively ensuring the stability of the slag bag operating vehicle, and thus ensuring the safety of the slag handling process.

[0031] Preferably, each of the grippers has a protrusion on the corresponding rail-grabbing block, and the protrusion and the rail-grabbing block are integrally formed. Each protrusion protrudes towards the rail. The side walls of the support blocks corresponding to the two protrusions are respectively provided with notches. Each notch is recessed towards the vertical center line of the support block, and the shape of each notch is suitable for the shape of the corresponding protrusion. When the pushing cylinder drives the support block to move down until the support block abuts against the top of the rail, the lower parts of the two protrusions abut against the corresponding side walls of the rail, and the upper parts of the two protrusions abut against the corresponding notches of the support block.

[0032] Through the above technical solution, by setting appropriate protrusions and notches, when the rail grabber grips the rail, the protrusions can restrict the movement of the support block, thereby improving the stability of the slag bag operating car.

[0033] Preferably, the bag-retrieving mechanism includes a support frame, symmetrically arranged rotating arms on both sides of the support frame, and lifting cylinders. The support frame is rotatably mounted on the slag bag operating vehicle. One end of each rotating arm is hinged to one end of the top of the support frame, and the other end of each rotating arm is hinged to a fork for holding the trunnion in the slag bag. A bag-turning locking cylinder for limiting the flipping limit plate in the slag bag is fixedly installed at the end of each rotating arm near the fork.

[0034] Each of the lifting cylinders is fixedly mounted on the other end of the top of the support frame, and the output shaft of each lifting cylinder is hinged to one end of the corresponding rotating arm. Each lifting cylinder is used to drive the corresponding rotating arm to rotate along the vertical plane where the hinge is located, so that the included angle between the rotating arm and the slag bag operating vehicle is between 0° and 125°.

[0035] Preferably, the first track group includes at least two first guide rails arranged in parallel and side by side, one end of each first guide rail extending to the slag outlet of the metal residue; a plurality of first crossrails for connecting adjacent first guide rails are provided.

[0036] By implementing the above technical solution and setting up no fewer than two first guide rails, the number of tracks available for slag bag transport vehicles is increased, thereby accelerating the transport efficiency of slag bags and improving the efficiency of slag treatment.

[0037] Preferably, it also includes a preparatory waiting station, which is provided with a first straight rail and multiple second straight rails. The multiple second straight rails are arranged in parallel and side by side, and one of the second straight rails is connected to the first track group. The other two second straight rails extend to the slag outlet of the metal residue. Each second straight rail is connected to the first straight rail. A second rotary table is provided at the connection point between each first straight rail and the second straight rail and at the connection point between each first straight rail and the first track group. Each second rotary table has the same structure as the first rotary table.

[0038] Through the above technical solution, by setting up a preparatory waiting station, multiple slag bag transport vehicles can be parked sequentially on the first or second straight rail of the preparatory waiting station, which can reduce the replacement time when each slag bag transport vehicle receives residue, thereby speeding up the processing efficiency of residue.

[0039] Preferably, it also includes a maintenance station, which has a second guide rail. One end of the second guide rail is connected to the first track group, and the other end of the second guide rail is provided with a maintenance area and a pre-maintenance area. A third rotary table is provided at the connection point between the second guide rail and the first track group, and each third rotary table has the same structure as the first rotary table.

[0040] The above technical solution, through the setting of the third rotary worktable, allows the slag bag transport vehicle to quickly adjust its direction, which not only speeds up production efficiency but also reduces the floor space required, thereby reducing costs.

[0041] Preferably, the conveying track assembly includes two parallel, side-by-side conveying guide rails.

[0042] In summary, the beneficial effects of a non-ferrous metal residue treatment system are as follows:

[0043] 1. With the slag bag operating vehicle, after the bag-retrieving mechanism picks up the slag bag, it is placed on the top of the slag bag operating vehicle. After placement, the bag-retrieving mechanism is retracted, and the slag bag operating vehicle drives the bag-retrieving mechanism to travel in a straight line along the conveyor track group, transporting the slag bag to the designated position in the cooling area. After cooling, the slag bag is picked up by the slag bag operating vehicle and the slag is dumped. During this process, because the bag-retrieving mechanism and the slag bag operating vehicle are rotated together, the structure is simple and the operation is quick. This means that the slag bag transport vehicle does not need to set up a corresponding channel for turning or turning, which can effectively avoid occupying more cooling station area. The space saved can be used to discharge more slag bags, and the slag bags can be placed in any position in the cooling area, thereby increasing the number of slag bags discharged.

[0044] It can also achieve automated control of the slag bag handling vehicle remotely. The slag bag handling vehicle can automatically pick up, put down and flip the bag. This can eliminate the need for operators on each slag bag handling vehicle, thereby basically eliminating safety hazards in the slag handling process and ensuring safety. Moreover, as the number of slag bag handling vehicles increases, there is no need to increase the number of personnel to remotely operate and control the slag bag handling vehicles, thereby reducing the input of labor costs.

[0045] In addition, the maintenance cost of the slag bag handling vehicle is low, and the slag bag handling vehicle is not affected by external weather changes, which can reduce the investment cost.

[0046] 2. Through the setting of the rail grabber, when the bag-retrieving mechanism is at different angles or the slag bag is in different operating states, the pressure and tension at different positions in the rail grabber are constantly switching. When a rail grabber needs to withstand pressure, the hydraulic cylinder drives the support block to press against the top of the rail, thereby transmitting the pressure to the rail. At this time, the two clamps of each rail grabber clamp the rail respectively, so that the slag bag operating vehicle can withstand the tension. Even if the clamps will move downward under the action of pressure, because the thickness of the clamps is less than the groove width of the groove on the side of the rail, the clamps can move in the groove, thus avoiding the tension being affected, thereby effectively ensuring the stability of the slag bag operating vehicle and ensuring the safety of the slag handling process.

[0047] 3. By setting appropriate protrusions and notches, when the rail grabber grips the rail, the protrusions can restrict the movement of the support block, thereby improving the stability of the slag bag operating car.

[0048] 4. By setting up no fewer than two first guide rails, the number of tracks available for slag bag transport vehicles is increased, thereby accelerating the transportation efficiency of slag bags and improving the efficiency of slag treatment.

[0049] 5. By setting up a waiting station, multiple slag bag transport vehicles can be parked sequentially on the first or second straight rail of the waiting station, which can reduce the replacement time when each slag bag transport vehicle receives slag, thereby speeding up the slag processing efficiency.

[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0061] In one possible embodiment, as shown in the appendix Figure 3-7 As shown, a non-ferrous metal slag treatment system includes a first track group 1, on which a slag bag transport vehicle 2 for transporting slag bags travels, and on one side of the first track group 1 there is a cooling station 3. On the first track group 1 corresponding to the cooling station 3, there are multiple first rotating worktables 4 for adjusting the direction of the slag bag transport vehicle 2.

[0062] The cooling station 3 is equipped with a conveyor rail group 5, which includes two parallel and side-by-side conveyor rails. Cooling areas for placing slag bags are formed on both sides of the conveyor rail group 5. A slag bag operating vehicle 6 travels on the conveyor rail group 5. A bag-retrieving mechanism 7 is provided on the slag bag operating vehicle 6. The slag bag operating vehicle 6 travels in a straight line to one side of the slag bag transport vehicle 2. The bag-retrieving mechanism 7 extends towards the slag bag on the slag bag transport vehicle 2. After removing the slag bag, the bag-retrieving mechanism 7 carries the slag bag back and places the slag bag on the slag bag operating vehicle 6.

[0063] The bag-retrieving mechanism 7 and the slag bag operating vehicle 6 rotate in coordination. The slag bag operating vehicle 6 carries the slag bag and travels in a straight line to the cooling area. After the bag-retrieving mechanism 7 rotates the slag bag by 90°, it lifts the slag bag and raises it above the cooling area. The bag-retrieving mechanism 7 then moves the slag bag downwards and places it in the cooling area.

[0064] On the side of cooling station 3 away from the first track group 1, there is a slag dumping station 8. The slag bag operating vehicle 6 travels in a straight line to the position of the cooled slag bag. The bag taking mechanism 7 rotates to face the slag bag. After the rotation is completed, the bag taking mechanism 7 lifts the slag bag and places it on the slag bag operating vehicle 6. The slag bag operating vehicle 6 carries the cooled slag bag and travels in a straight line to the slag dumping station 8. The bag taking mechanism 7 rotates to face the slag dumping station 8. After the rotation is completed, the bag taking mechanism 7 lifts the slag bag above the slag dumping station 8. The bag taking mechanism 7 performs the slag dumping operation on the slag bag. After the slag dumping is completed, the bag taking mechanism 7 carries the empty slag bag back and places the empty slag bag on the slag bag operating vehicle 6.

[0065] When the slag bag transport vehicle 2 moves the slag bag to one side of the cooling station 3, the first rotating worktable 4 drives the slag bag transport vehicle 2 to rotate, causing the slag bag on it to rotate to the side of the corresponding slag bag operating vehicle 6. This makes it easier for the slag bag operating vehicle 6 to pick up the bag. After the bag picking mechanism 7 picks up the slag bag, it first places the slag bag on top of the slag bag operating vehicle 6. After placement, the slag bag operating vehicle 6 drives the bag picking mechanism 7 to travel along the conveyor track group 5 to transport the slag bag to the designated position in the cooling area. Then, the bag picking mechanism 7 drives the slag bag to rotate, thereby adjusting the position of the slag bag. After the slag bag is adjusted, the bag picking mechanism 7 is controlled to put the slag bag down. During this process, because the bag picking mechanism 7 and the slag bag operating vehicle 6 are rotated together, the structure is simple and the operation is quick. This means that the slag bag transport vehicle 2 does not need to set up a corresponding channel for turning or turning. This can effectively avoid occupying more area of ​​the cooling station 3, and the space saved can be used to discharge more slag bags, thereby increasing the number of slag bags discharged.

[0066] When using a cooling station 3 of the same area, in this specific embodiment, the cooling station 3 is equipped with three slag bag operating vehicles 6. Only three sets of straight conveying track groups 5 need to be set up in the cooling station 3 for the use of the slag bag operating vehicles 6. Each slag bag operating vehicle 6 can place slag bags on both sides along the length of the conveying track group 5. Each row can hold 28 slag bags. Therefore, a total of 28*2*3=168 slag bags can be placed at this cooling station 3.

[0067] If a gantry crane is used to discharge slag bags, the slag bag transport vehicle 2 needs to travel within the grabbing range of the gantry crane hook. Therefore, this method can discharge 20*8+12=172 slag bags, just as... Figure 1 As shown, the number of slag bags discharged using this method is the same as that discharged using the gantry crane method. However, the slag bag operating vehicle 6 in this method has a simple structure, while the gantry crane has a complex structure. The installation of the gantry crane requires the use of wire rope to drive the hook to move. During the handling of slag bags, the wire rope is prone to swaying, and the movement of the hook on the wire rope cannot be automatically controlled.

[0068] If a tanker truck is used to discharge the slag bags, the truck needs to make U-turns, turns, and other maneuvers, which requires a large area for the transport road. Therefore, this method can only discharge 16*8=128 slag bags, just as... Figure 2 As shown.

[0069] The slag bag handling vehicle 6 can achieve automated control, thereby realizing automated bag picking, bag placement and bag flipping operations. This can eliminate the need for operators on each slag bag handling vehicle 6, thus basically eliminating safety hazards in the slag handling process and ensuring safety. Moreover, as the number of slag bag handling vehicles 6 increases, there is no need to increase the number of personnel to remotely operate and control the slag bag handling vehicles 6, thereby reducing the input of labor costs.

[0070] In addition, the maintenance cost of the slag bag operating car 6 is low, and the slag bag operating car 6 is not affected by external weather changes, thereby reducing investment costs.

[0071] The front and rear ends of the slag bag operating vehicle 6 are respectively equipped with rail grabbers 9 corresponding to the positions of the conveying rail group 5. Each rail grabber 9 has the same structure. The rail grabber 9 includes rail grabbing blocks 901 symmetrically arranged on both sides of the rail and a push cylinder 902. Both rail grabbing blocks 901 are rotated with the slag bag operating vehicle 6. Each of the two rail grabbing blocks 901 has a clamping gripper 23 on the side of the lower part that is close to each other. The thickness of each clamping gripper 23 is less than the groove width of the corresponding side groove of the rail.

[0072] The two rail grabbing blocks 901 are connected by a return spring 24, and the return spring 24 is located above the hinge point between the rail grabbing block 901 and the slag bag operating car 6.

[0073] The hydraulic cylinder 902 is fixedly installed on the slag bag operating vehicle 6. The piston rod of the hydraulic cylinder 902 is connected to the support block 27. The support block 27 is vertically positioned between the two rail grabbing blocks 901 and above the rail. The support block 27 and the two rail grabbing blocks 901 are in a sliding fit.

[0074] When the hydraulic cylinder 902 pushes the support block 27 downward to abut against the rail, the grippers 23 of the two rail gripping blocks 901 abut against the bottom of the groove on the corresponding side of the rail, so that the rail gripper 9 can withstand both pressure and tension.

[0075] When the bag-retrieving mechanism 7 is at different angles or the slag bag is in different operating states, the pressure and tension at different positions in the rail grabber 9 are constantly switching. When a rail grabber 9 needs to withstand pressure, the hydraulic cylinder 902 is pushed to drive the support block 27 so that the support block 27 abuts against the top of the rail, thereby transmitting the pressure to the rail. At this time, the two clamps 23 of each rail grabber 9 clamp the rail respectively, so that the slag bag operating vehicle 6 can withstand the tension. Even if the clamps 23 will move downward under the action of pressure, because the thickness of the clamps 23 is less than the groove width of the groove on the side of the rail, the clamps 23 can move in the groove, thereby avoiding the tension being affected, thus effectively ensuring the stability of the slag bag operating vehicle 6, and thus ensuring the safety of the slag handling process.

[0076] Each grabber 23 has a protrusion 25 on its corresponding rail grabbing block 901, and the protrusion 25 and the rail grabbing block 901 are integrally formed. Each protrusion 25 protrudes towards the rail. The side wall of the support block 27 corresponding to the two protrusions 25 is provided with a notch 26. Each notch 26 is recessed towards the vertical center line of the support block 27, and the shape of each notch 26 is suitable for the shape of the corresponding protrusion 25. When the hydraulic cylinder 902 drives the support block 27 to move down until the support block 27 abuts against the top of the rail, the lower part of the two protrusions 25 abuts against the corresponding side wall of the rail, and the upper part of the two protrusions 25 abuts against the corresponding notch 26 of the support block 27. When the rail grabber 9 is controlled to grip the rail, after the protrusions 25 and notches 26 are aligned, the protrusions 25 can restrict the movement of the support block 27, thereby improving the stability of the slag bag operating car 6.

[0077] The bag-retrieving mechanism 7 includes a support frame 701, swivel arms 702 symmetrically arranged on both sides of the support frame 701, and lifting cylinders 703. The support frame 701 is rotatably mounted on the slag bag operating vehicle 6. One end of each swivel arm 702 is hinged to one end of the top of the support frame 701, and the other end of each swivel arm 702 is hinged to a fork head 13 for holding the trunnion in the slag bag. A bag-turning locking cylinder 14 for limiting the flipping limit plate in the slag bag is fixedly installed at one end of each swivel arm 702 near the fork head 13. When the bag-turning locking cylinder 14 is working, the output shaft of the bag-turning locking cylinder 14 is extended to lock the flipping limit plate in the slag bag.

[0078] Each lifting cylinder 703 is fixedly mounted on the other end of the top of the support frame 701, and the output shaft of each lifting cylinder 703 is hinged to one end of the middle of the corresponding rotating arm 702. Each lifting cylinder 703 is used to drive the corresponding rotating arm 702 to rotate vertically along the plane where the hinge is located, so that the included angle between the rotating arm 702 and the slag bag operating vehicle 6 is 0°-125°.

[0079] In this specific embodiment, the connection between the support frame 701 and the slag bag operating vehicle 6 is as follows: a reduction motor 10 is fixedly installed on the slag bag operating vehicle 6, the output shaft of the reduction motor 10 is vertically arranged, and a gear 11 is fixedly sleeved on the output shaft of the reduction motor 10; a slewing bearing 12 with external teeth is rotatably installed at the top of the slag bag operating vehicle 6, and the slewing bearing 12 and the gear 11 are meshed together, and the support frame 701 is fixedly installed on the top of the slewing bearing 12.

[0080] The first track group 1 includes at least two first guide rails arranged in parallel and side by side. One end of each first guide rail extends to the slag outlet of the metal residue. Multiple first crossrails 22 are provided between adjacent first guide rails to achieve connection. In this specific embodiment, two first guide rails are provided. When the residue is processed, more slag bag transport vehicles 2 can travel on each first guide rail, thereby speeding up the transportation efficiency of the slag bags and improving the residue processing efficiency.

[0081] It also includes a preparatory waiting station, which is equipped with a first straight rail 15 and multiple second straight rails 16. The multiple second straight rails 16 are arranged in parallel and parallel order, and one of the second straight rails 16 is connected to the first track group 1. The other two second straight rails 16 extend to the slag outlet of the metal residue. Each second straight rail 16 is connected to the first straight rail 15. A second rotary worktable 17 is provided at the intersection of each first straight rail 15 and the second straight rail 16 and at the connection between the first straight rail 15 and the first track group 1. Each second rotary worktable 17 has the same structure as the first rotary worktable 4.

[0082] Before processing the residue, multiple slag bag transport vehicles 2 can be parked sequentially on the first straight rail 15 or the second straight rail 16 at the waiting station. This can reduce the replacement time for each slag bag transport vehicle 2 when receiving residue, thereby speeding up the processing efficiency of the residue.

[0083] It also includes a maintenance station, on which multiple second guide rails 18 are arranged in parallel. One end of each second guide rail 18 is connected to the first track group 1. The other end of one of the second guide rails 18 is provided with a maintenance area 19 and a pre-maintenance area 20. A second crossrail is provided between two adjacent second guide rails 18 for connecting them. A third rotary table 21 is provided at the connection point between each second guide rail 18 and the first track group 1. Each third rotary table 21 has the same structure as the first rotary table 4.

[0084] The first rotary worktable 4, the second rotary worktable 17, and the third rotary worktable 21 can quickly adjust the direction of the slag bag transport vehicle 2, which can not only speed up production efficiency but also reduce the floor space occupied, thereby reducing costs.

[0085] It is common knowledge that a power center is set up on one side of the first track group 1 to provide electricity to the slag bag transport vehicle 2 and the slag bag operating vehicle 6, so it will not be elaborated on here. It is also common knowledge that the power center is equipped with circulating water, so it will not be elaborated on here.

[0086] Operation Process: Multiple slag bag transport vehicles 2 carrying empty slag bags travel along the first guide rail. When slag processing is not required, the slag bag transport vehicles 2 can be parked on the first straight rail 15 or the second straight rail 16. When slag processing is required, the slag bag transport vehicles 2 travel sequentially to the slag receiving point to receive slag. After receiving slag, the slag bag transport vehicles 2 travel along the first guide rail to one of the first rotating worktables 4. The first rotating worktable 4 rotates the slag bag transport vehicles 2 90°, so that the slag bags transported on them face the cooling station 3. At this time, the slag bag operating vehicle 6 travels along the conveying guide rail to one side of the slag bag transport vehicle 2 and removes the slag bag from the slag bag transport vehicle 2. After removal, the slag bag is placed on the top of the support frame 701. The slag bag operating vehicle 6 is controlled to travel along the conveying guide rail, and the slag bag is rotated by controlling the bag-retrieving mechanism 7. After rotation, the bag-retrieving mechanism 7 is controlled to place the slag bag in the designated position at the cooling station 3. After a certain slag bag has cooled down... The slag bag operating vehicle 6 travels along the conveying guide rail to the location of the slag bag, takes the slag bag from the cooling station 3, and transports it to the slag dumping station 8. The slag bag operating vehicle 6 is controlled to rotate the slag bag, so that the slag bag is on one side of the slag dumping station 8. The bag taking mechanism 7 is controlled to rotate the slag bag 125°, so that all the residue in the slag bag is dumped out. After dumping, it rotates 125° in the opposite direction and returns to the slag bag transport vehicle 2 with the empty slag bag. The bag taking mechanism 7 is controlled to rotate the slag bag and put the empty slag bag back onto the slag bag transport vehicle 2. The slag bag transport vehicle 2 returns to the slag receiving point or the first straight rail 15 or the second straight rail 16. When repair is needed, the slag bag transport vehicle 2 or the slag bag operating vehicle 6 can be driven to the maintenance area 19 at the third rail. When there are too many vehicles waiting to be repaired, they can be temporarily driven to the preparatory maintenance area 20 to wait. During this process, the pressure and tension of different positions can be switched through the rail grabber.

Claims

1. A non-ferrous metal residue treatment system, comprising a first track group, on which a slag bag transport vehicle for transporting slag bags travels, a cooling station on one side of the first track group, and a plurality of first rotary worktables for adjusting the direction of the slag bag transport vehicle are provided on the first track group corresponding to the cooling station. Its features are, The cooling station is equipped with a conveyor rail assembly, with cooling areas formed on both sides of the conveyor rail assembly for placing slag bags. A slag bag handling vehicle travels on the conveyor rail assembly, and the slag bag handling vehicle is equipped with a bag-retrieving mechanism. When retrieving a slag bag, the bag-retrieving mechanism extends to remove the slag bag from the slag bag transport vehicle and places it on the slag bag handling vehicle. After the slag bag is placed, the bag-retrieving mechanism retracts, and the slag bag handling vehicle carries the slag bag in a straight line to the cooling area. The bag-retrieving mechanism and the slag bag operating vehicle are rotated together. When the cooling operation is performed, the bag-retrieving mechanism rotates the slag bag by 90°, then extends to remove the slag bag from the slag bag operating vehicle and places it in the cooling area. After the slag bag is placed, the bag-retrieving mechanism retracts. The cooling station has a slag dumping station on the side away from the first track group. When the slag dumping operation is performed, the slag bag operating vehicle travels in a straight line to the position of the cooled slag bag, the bag picking mechanism rotates to face the slag bag, the bag picking mechanism extends to take off the slag bag and place it on the slag bag operating vehicle, the slag bag operating vehicle carries the cooled slag bag and travels in a straight line to the slag dumping station, the bag picking mechanism carries the slag bag and rotates to face the slag dumping station, the bag picking mechanism dumps the slag bag, after the slag dumping is completed, the bag picking mechanism carries the empty slag bag back and places the empty slag bag on the slag bag operating vehicle; The front and rear ends of the slag bag operating vehicle are respectively equipped with rail grippers corresponding to the positions of the conveying track group, and each rail gripper has the same structure. The rail gripper includes rail gripping blocks symmetrically arranged on both sides of the rail and a push cylinder. Both rail gripping blocks are rotatably engaged with the slag bag operating vehicle. Each of the two rail gripping blocks has a clamp on the side of its lower part that is close to each other. The thickness of each clamp is less than the groove width of the corresponding side groove of the rail. The two rail gripping blocks are connected by a return spring, and the return spring is located above the hinge point between the rail gripping block and the slag bag operating vehicle. The push cylinder is fixedly installed on the slag bag operating vehicle. The piston rod of the push cylinder is connected to a support block.
