Description

Technical Field

[0001] The present invention relates to an automatic casting system for anodic phosphorus cast iron, belonging to the technical field of automatic casting process for carbon blocks and carbon bowls in the aluminum electrolysis anodic assembly workshop, as well as related application fields such as metallurgical automatic casting. Background Art

[0002] In the process of aluminum electrolysis production, the anodic assembly workshop is mainly responsible for assembling anodic carbon blocks with steel claws suspended on a catenary, and then pouring molten iron through a casting station to integrally cast the carbon blocks and steel claws. After assembly, the carbon blocks are transported to the electrolysis workshop, and a multifunctional overhead crane in the workshop grabs the steel claws to transport the carbon blocks into the electrolytic cell for reaction to produce molten aluminum.

[0003] In the foregoing process, the casting station is responsible for integrally combining anodic guide rods that have been cleaned, straightened, preheated, and coated with graphite with anodic carbon blocks by casting molten phosphorus cast iron. Currently, in this process, on-site workers need to pour the phosphorus cast iron in the intermediate frequency melting furnace into a ladle, clean the dross on the surface of the molten iron, and then manually operate the ladle to pour the molten iron into each carbon bowl of the carbon block in sequence.

[0004] The applicant has found in the long-term production process that the existing casting process has the following problems:

[0005] 1. Safety problems. Since the temperature of the molten phosphorus cast iron is about 1500 degrees Celsius, the heat radiation generated by the molten iron during the casting process will seriously affect the physical health of workers. During the casting process of the molten iron, the molten iron splashes, and it often burns the on-site workers, posing a great safety hazard. At the same time, a large amount of flue gas is generated during the contact between the molten iron and the carbon block, and long-term inhalation of this flue gas by on-site workers will also cause great harm to physical health.

[0006] 2. Precision problems. Since the inner wall of the anodic guide rod and the carbon bowl of the carbon block has a gap of only about 15 mm, it is difficult for workers to accurately pour the molten iron into each carbon bowl by operating the ladle in the operation room, resulting in poor casting quality and low efficiency.

[0007] 3. Cost problems. Take the anodic assembly workshop of a 400KA aluminum electrolysis plant as an example. Currently, the casting station operates in two shifts, with 4 operators in each shift, and a total of 8 operating workers are required. The company's labor cost for each worker at this station is 100,000 yuan per year, and the annual labor cost of the casting station is 800,000 yuan. Summary of the Invention

[0008] Based on the above, the present invention provides an automatic casting system for anodic phosphorus cast iron with high safety, good casting effect, and low cost to overcome the deficiencies of the prior art.

[0009] The technical solution of the present invention is: an automatic casting system for anodic phosphorus cast iron, including a roller conveyor and a suspension conveyor. The suspension conveyor is arranged above the roller conveyor. The roller conveyor and the suspension conveyor synchronously convey carbon blocks and steel bars, and the lower end of the steel bar extends into the carbon bowl of the carbon block. The system further includes a casting system, which includes:

[0010] A bracket;

[0011] A positioning mechanism, arranged on the roller conveyor, for fixing the position of the carbon block;

[0012] A casting mechanism, including a liquid storage container and a diversion pipe. The liquid storage container is arranged on the bracket. The bottom surface of the liquid storage container is provided with diversion holes, and the diversion pipe is connected to the diversion holes;

[0013] A flow stopping mechanism, including a first driving mechanism and a plunger rod. The first driving mechanism is used to drive the plunger rod to move up and down, and the plunger rod is located above the liquid storage container;

[0014] Wherein, the system includes a first state and a second state. In the first state, the positioning mechanism positions the carbon block at a predetermined position on the roller conveyor, and the first driving mechanism drives the plunger rod to move upward away from the diversion holes, so that the diversion holes are opened to deliver the casting liquid into the carbon bowl; in the second state, the first driving mechanism drives the plunger rod to move downward to block the diversion holes.

[0015] In one example, the bracket includes:

[0016] A first bracket;

[0017] A lifting mechanism, arranged on the first bracket;

[0018] A second bracket, arranged on the lifting mechanism;

[0019] Wherein, the second bracket can move up and down following the lifting mechanism.

[0020] In one example, the liquid storage container is arranged on the second bracket. The liquid storage container includes a liquid receiving pipe and a diversion groove. The diversion groove is connected to the liquid receiving pipe. The diversion groove is arranged in the direction close to the roller conveyor, and the diversion holes are formed on the bottom surface of the diversion groove.

[0021] In one example, the casting system further includes a current intercepting mechanism, and the current intercepting mechanism includes:

[0022] A current intercepting bracket, arranged above the liquid receiving pipe;

[0023] The fourth driving mechanism is disposed on the intercepting bracket and is used to provide power.

[0024] The intercepting plate is movably disposed on the liquid receiving pipe.

[0025] Wherein, as the fourth driving mechanism drives the intercepting plate to move up and down, the intercepting plate can make the liquid receiving pipe move between a conducting state and a closed state.

[0026] In one example, the liquid receiving pipe is sequentially provided with a silicon carbide inner lining, a silicon aluminum heat insulation layer, an intermediate frequency induction coil, a magnetic isolation sheet, a heat preservation layer and a metal shell from inside to outside.

[0027] In one example, the diversion pipe is sequentially a high temperature resistant layer, an intermediate frequency induction coil and a metal shell from inside to outside.

[0028] In one example, the positioning mechanism includes:

[0029] The longitudinal positioning sub-mechanism includes a longitudinal support, a second driving mechanism and a first rotating clamp. The longitudinal support is fixedly disposed above the roller conveyor. The two first rotating clamps are respectively rotatably disposed on both sides of the longitudinal support. The second driving mechanism can drive the rotation of the first rotating clamp.

[0030] The transverse positioning sub-mechanism includes a transverse support, a third driving mechanism and a second rotating clamp. The transverse support is fixedly disposed on the roller conveyor and is located below the driving roller. The second rotating clamp is rotatably disposed on the transverse support. The third driving mechanism can drive the rotation of the second rotating clamp.

[0031] Wherein, the positioning mechanism can move between a positioning state and a contraction state. In the positioning state, the second driving mechanism drives the free ends of the two first rotating clamps to rotate in opposite directions in the horizontal direction at the same time, and the longitudinal positions of the carbon blocks are fixed by the two first rotating clamps. The third driving mechanism drives the free end of the second rotating clamp to rotate in the direction towards the carbon block in the vertical plane, and the transverse position of the carbon block is fixed by the second rotating clamp and the longitudinal support together. In the contraction state, the second driving mechanism drives the free ends of the two first rotating clamps to rotate in the opposite direction, so that the free ends of the first rotating clamps contract to the side of the roller conveyor. The third driving mechanism drives the free end of the second rotating clamp to rotate in the direction away from the carbon block, so that the free end of the second rotating clamp contracts below the driving roller.

[0032] In one example, the casting system further includes:

[0033] The first detection mechanism is arranged above the roller conveyor and is used to sense whether the carbon block moves to the positioning position of the positioning mechanism.

[0034] In one example, the casting system further includes:

[0035] The second detection mechanism is arranged above the roller conveyor and is used to sense whether the casting liquid in the carbon bowl reaches the predetermined height position.

[0036] In one example, the casting system further includes:

[0037] The liquid receiving box is arranged below the roller conveyor and is used to receive the splashed casting liquid.

[0038] The beneficial effects of the present invention are as follows: The working mode of this casting system is that when the roller conveyor and the suspension conveyor synchronously convey the carbon block and the steel rod forward to the casting position, the roller conveyor and the suspension conveyor stop synchronously. At the same time, the positioning mechanism positions and fixes the carbon block. At this time, the lower port of the diversion pipe is exactly above the carbon bowl. Then, the first driving mechanism drives the plunger rod to move upward to open the diversion hole, and the molten iron in the liquid storage container can be diverted to the carbon bowl through the diversion pipe, realizing the one-time automatic casting and forming of several steel rods and the carbon block, thereby greatly improving the casting efficiency. After casting is completed, the first driving mechanism drives the plunger rod to move downward to block the diversion hole, and the positioning mechanism no longer fixes the carbon block. At this time, the roller conveyor and the suspension conveyor can continue to convey the cast carbon block and steel rod to the next working station, realizing the automatic casting function of the entire carbon block. Compared with the prior art, this casting system changes manual casting to automatic equipment casting, which can greatly improve the casting efficiency, reduce the casting cost, and ensure the safety of the workers.

The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0066] Please refer to Figures 1 to 6 , an automatic casting system for anodic phosphor iron in an embodiment of the present invention includes a roller conveyor and a suspension conveyor. The suspension conveyor is installed above the roller conveyor, and the carbon block and the steel bar are synchronously conveyed by the roller conveyor and the suspension conveyor, and the lower end of the steel bar extends into the carbon bowl of the carbon block. In the working state, the carbon block and the steel bar are first assembled at the front ends of the two conveyors. The carbon block is placed on the driving roller of the roller conveyor, the upper end of the steel bar is fixed on the suspension conveyor, and the lower end of the steel bar is inserted into the carbon bowl of the carbon block. Then, the carbon block and the steel bar are synchronously conveyed forward by the roller conveyor and the suspension conveyor.

[0067] In order to automatically introduce the molten iron at the casting station into the carbon bowl to achieve automatic casting, a casting system is installed at the casting station in the present invention. The casting system includes a bracket 1, a positioning mechanism 2, a casting mechanism 3 and a flow stopping mechanism 4. Among them, the bracket 1 is used to support the casting mechanism 3 and the flow stopping mechanism 4; the positioning mechanism 2 is installed on the roller conveyor and is used to fix the position of the carbon block; the casting mechanism 3 includes a liquid storage container 31 and a diversion pipe 32. The liquid storage container 31 is installed on the bracket 1, a diversion hole is provided at the bottom surface of the liquid storage container 31, and the diversion pipe 32 is connected to the diversion hole. The molten iron in the liquid storage container 31 can be discharged through the diversion pipe 32; the flow stopping mechanism 4 includes a first driving mechanism 41 and a plunger rod 42. The first driving mechanism 41 is used to drive the plunger rod 42 to move up and down, and the plunger rod 42 is located above the liquid storage container 31. This casting system includes a first state and a second state. In the first state, the positioning mechanism 2 positions the carbon block at a predetermined position on the roller conveyor, and the first driving mechanism 41 drives the plunger rod 42 to move upward away from the diversion hole to make the diversion hole conduct, so as to convey the casting liquid to the carbon bowl, thereby realizing automatic casting; in the second state, the first driving mechanism 41 drives the plunger rod 42 to move downward to block the diversion hole.

[0068] In this embodiment, the number of the diversion pipes 32 is the same as and corresponds to the number of the carbon bowls on the carbon blocks. The diversion pipes 32 can be arranged obliquely. The first driving mechanism 41 can be a hydraulic cylinder. The hydraulic cylinder is vertically installed on the bracket 1. The free end of the telescopic rod of the hydraulic cylinder is connected to the top end of the plunger rod 42 through a connecting rod. By the telescopic movement of the telescopic rod of the hydraulic cylinder, the plunger rod 42 can be driven to move up and down.

[0069] The working mode of this casting system is as follows: when the roller conveyor and the suspension conveyor synchronously convey the carbon blocks and steel rods forward to the casting position, the roller conveyor and the suspension conveyor stop synchronously. At the same time, the positioning mechanism 2 positions and fixes the carbon blocks. At this time, the lower port of the diversion pipe 32 is exactly above the carbon bowls. Then, the first driving mechanism 41 drives the plunger rod 42 to move upward to open the diversion holes, and the molten iron in the liquid storage container 31 can be diverted into the carbon bowls through the diversion pipes 32, realizing the one-time automatic casting and forming of several steel rods and carbon blocks, thereby greatly improving the casting efficiency. After the casting is completed, the first driving mechanism 41 drives the plunger rod 42 to move downward to block the diversion holes, and the positioning mechanism 2 no longer fixes the carbon blocks. At this time, the roller conveyor and the suspension conveyor can continue to convey the cast carbon blocks and steel rods to the next working station, realizing the automatic casting function of the entire carbon block. Compared with the prior art, this casting system changes the manual casting to automatic equipment casting, which can greatly improve the casting efficiency, reduce the casting cost, and ensure the safety of the workers.

[0070] It should be particularly noted that this casting system only needs to position the carbon blocks and does not need to position the steel rods. The reason is that the suspension conveyor can achieve the precise hovering of the steel rods, while the carbon blocks may horizontally shift on the roller conveyor. Therefore, as long as the accurate position of the carbon blocks during casting is ensured, the precise positioning casting of the steel rods and carbon blocks can be ensured.

[0071] In this casting system, the bracket 1 includes a first bracket 11, a lifting mechanism 12, and a second bracket 13. The lifting mechanism 12 is installed on the first bracket 11, and the second bracket 13 is installed on the lifting mechanism 12. The second bracket 13 can move up and down following the lifting mechanism 12. In this embodiment, the lower end of the second bracket 13 can be sleeved on the first bracket 11, and the lifting mechanism 12 is installed between the first bracket 11 and the second bracket 13. As the lifting mechanism 12 moves up and down, the second bracket 13 can move up and down relative to the first bracket 11. The lifting mechanism 12 can be a hydraulic cylinder.

[0072] In the present casting system, the liquid container 31 is installed on the second bracket 13. The liquid container 31 includes a liquid receiving pipe 311 and a diverter trough 312. The diverter trough 312 is connected to the liquid receiving pipe 311. The diverter trough 312 is arranged close to the roller conveyor, and the diverter hole is formed on the bottom surface of the diverter trough 312. In the working state, the liquid receiving pipe 311 guides the molten iron into the diverter trough 312, and then the diverter trough 312 guides the molten iron into the carbon bowl through the guide pipe 32. Since the liquid container 31 can follow the second bracket 13 to move up and down, when the carbon block is positioned, the second bracket 13 can be moved down by the lifting mechanism 12. At this time, the guide pipe 32 also moves down with it, and its lower end is close to the end of the carbon bowl to avoid the splashing of the cast iron as much as possible.

[0073] The casting system also includes a cut-off mechanism 5, which includes a cut-off bracket 51, a fourth driving mechanism 52 and a cut-off plate 53. The cut-off bracket 51 is installed above the liquid receiving pipe 311; the fourth driving mechanism 52 is installed on the cut-off bracket 51 to provide power; and the cut-off plate 53 is movably arranged on the liquid receiving pipe 311. During operation, as the fourth driving mechanism 52 drives the cut-off plate 53 to move up and down, the cut-off plate 53 can make the liquid receiving pipe 311 move between the conducting state and the closed state. In this embodiment, the fourth driving mechanism 52 can be a hydraulic cylinder. After the casting is completed, the liquid receiving pipe 311 can be closed by the fourth driving mechanism 52, so that the liquid container 31 can be easily cleaned. In this embodiment, in order to prevent the molten iron from entering the guide pipe 32 and causing blockage, which affects the casting, an iron grid 313 for filtering the molten iron is installed in the liquid receiving pipe 311.

[0074] In the present casting system, the liquid receiving pipe 311 is provided with silicon carbide lining, aluminum silicate insulation layer, medium frequency induction coil, magnetic isolation sheet, insulation layer and metal shell from inside to outside. During the casting process, the medium frequency induction coil is energized to realize the continuous heating function of the molten iron, so that the molten iron will not solidify in the pipe wall.

[0075] In the present casting system, the flow guide tube 32 is composed of a high temperature resistant layer, a medium frequency induction coil and a metal shell from the inside to the outside. During the casting process, the medium frequency induction coil is energized to achieve continuous heating of the molten iron, so that the molten iron will not solidify in the flow guide tube 32.

[0076] In the present casting system, the positioning mechanism 2 comprises a longitudinal positioning sub-mechanism 21 and a transverse positioning sub-mechanism 22, and the positioning mechanism 2 is mainly used to position and fix the carbon block.

[0077] The longitudinal positioning sub - mechanism 21 includes a longitudinal support 211, a second driving mechanism 212 and a first rotating clamp 213. The longitudinal support 211 is fixedly arranged above the roller conveyor. The two first rotating clamps 213 are respectively rotatably arranged on both sides of the longitudinal support 211, and the second driving mechanism 212 can drive the rotation of the two first rotating clamps 213. Specifically, the longitudinal support 211 is installed along the length direction of the roller conveyor on the side of the driving roller, and the inner side surface of the longitudinal support 211 is a plane, while the outer side of the longitudinal support 211 is fixed on the first bracket 11. The second driving mechanism 212 can be a hydraulic cylinder. One hydraulic cylinder is installed at each end of the longitudinal support 211. The free end of the telescopic rod of the hydraulic cylinder is hinged to one end of the first rotating clamp 213, and the two first rotating clamps 213 are respectively driven by these two hydraulic cylinders to rotate.

[0078] The transverse positioning sub - mechanism 22 includes a transverse support 221, a third driving mechanism 222 and a second rotating clamp 223. The transverse support 221 is fixedly arranged on the roller conveyor and is located below the driving roller. The second rotating clamp 223 is rotatably arranged on the transverse support 221, and the third driving mechanism 222 can drive the rotation of the second rotating clamp 223. Specifically, there are two transverse supports 221, which are respectively installed in parallel on the frame of the roller conveyor. The number of the second rotating clamps 223 is two, which are respectively rotatably installed on the two transverse supports 221. The third driving mechanism 222 can be a hydraulic cylinder. The free end of the telescopic rod of the hydraulic cylinder is hinged to one end of the second rotating clamp 223, and the two second rotating clamps 223 are respectively driven by these two hydraulic cylinders to rotate. When, if the distance between the hydraulic cylinder and the second rotating clamp 223 is relatively far, a transmission component 224 can be arranged therebetween.

[0079] The positioning mechanism 2 can move between a positioning state and a retracted state. In the positioning state, the second driving mechanism 212 drives the free ends of the two first rotating clamps 213 to rotate in opposite directions horizontally at the same time, and the longitudinal position of the carbon block is fixed by the two first rotating clamps 213. The third driving mechanism 222 drives the free end of the second rotating clamp 223 to rotate towards the carbon block in the vertical plane, and the transverse position of the carbon block is jointly fixed by the second rotating clamp 223 and the longitudinal support 211, thereby realizing the precise positioning of the carbon block. In the retracted state, the second driving mechanism 212 drives the free ends of the two first rotating clamps 213 to rotate in the reverse direction, so that the free ends of the first rotating clamps 213 retract to the side of the roller conveyor. The third driving mechanism 222 drives the free end of the second rotating clamp 223 to rotate away from the carbon block, so that the free end of the second rotating clamp 223 retracts below the driving roller, without affecting the continuous movement of the carbon block.

[0080] The casting system also includes a first detection mechanism 6, which is arranged above the roller conveyor and is used to sense whether the carbon block has moved to the positioning position of the positioning mechanism 2. The first detection mechanism 6 can be a laser sensor. When the carbon block enters the casting area through the roller conveyor, the laser sensor detects the moment of the carbon block and transmits the detection signal to the controller. The controller sends a control signal to stop the roller conveyor and the hanging conveyor. The carbon block stops in the specified area and is then accurately positioned by the positioning mechanism 2 to wait for casting.

[0081] The casting system also includes a second detection mechanism 7, which is arranged above the roller conveyor and is used to sense whether the casting liquid in the carbon bowl has reached a predetermined height position. In this embodiment, the second detection mechanism 7 can be composed of four groups of laser detectors fixed on the side frame of the roller conveyor, installed on the side of the conveyor according to the distribution width of the carbon block carbon bowl, and fixed on the side frame.

[0082] The casting system further comprises a liquid receiving box 8, which is arranged below the roller conveyor and is used to receive the splashed casting liquid. The liquid receiving box 8 serves as a safety device to receive the molten iron flowing outside the carbon bowl to prevent the molten iron from overflowing and causing safety accidents.

[0083] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
