Description

Technical Field

[0001] This invention relates to the field of anode carbon block production technology, and in particular to a waste heat recovery cooling device and method for anode carbon blocks. Background Technology

[0002] Anode carbon blocks refer to carbon blocks produced using petroleum coke and pitch coke as aggregates and coal tar pitch as a binder, used as anode materials in prebaked aluminum electrolysis cells. These carbon blocks have been roasted and have a stable geometric shape, so they are also called prebaked anode carbon blocks, or conventionally, carbon anodes for aluminum electrolysis.

[0003] After the anode carbon blocks are roasted, the high-temperature carbon blocks are removed from the roasting furnace by a multi-functional overhead crane and placed in a dedicated cooling device or buffer cooling silo. During the cooling process, the heat taken away from the high-temperature carbon blocks is not completely wasted; it can be recovered for power generation or to provide heat for other equipment on the production line, thus achieving the cascade utilization of energy.

[0004] However, traditional cooling equipment may have spray dead zones when using water mist cooling, making it difficult for the anode carbon block to be cooled evenly by the water mist. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a waste heat recovery cooling device for anode carbon blocks, which more precisely solves the problems mentioned in the background art.

[0006] This invention is achieved through the following technical solution: This invention proposes a waste heat recovery cooling device for anode carbon blocks, including a cooling box. A nozzle for water spraying and cooling is fixedly installed on the top surface of the inner wall of the cooling box, and a rotating lifting platform for carrying materials is fixedly installed on the bottom surface of the inner wall of the cooling box. A triangular plate is provided inside the cooling box, as well as a cooling mechanism for driving the triangular plate. A flipping mechanism is provided on the triangular plate.

[0007] Preferably, the cooling mechanism includes a horizontal plate fixed to the side wall of the cooling box, a rectangular plate fixedly connected to the free end of the horizontal plate, a square track fixedly installed on the surface of the rectangular plate, a notch at one corner of the square track, a support seat rotatably connected to the rectangular plate at the notch of the track, the support seat being located at the intersection of the extended lines of the two ends of the track, and a movable rod telescopically connected to the support seat passing through the support seat.

[0008] Preferably, a main shaft driven by an external motor is rotatably connected to the surface of the rectangular plate. The main shaft is located at the center of the track. An insert rod is passed through the end of the main shaft away from the rectangular plate and is telescopically connected to it. A mounting base is fixedly connected to the free end of the insert rod. A sliding column is rotatably connected to the mounting base. One end of the sliding column extends into the track and is slidably adapted to the track. A column is rotatably connected to the other end of the sliding column. The movable rod passes through the column and is fixedly connected to the column.

[0009] Preferably, one end of the movable rod is fixedly connected to a bearing seat, and the triangular plate is rotatably connected to the side wall of the bearing seat.

[0010] Preferably, the movable rod has two symmetrically distributed grooves at the end away from the bearing seat. Two L-plates are fixedly connected to the two side walls of the rectangular plate. Each L-plate is rotatably connected to an external spline shaft driven by a motor. An internal spline shaft adapted to the external spline shaft is telescopically connected to it. A retainer is fixedly connected to one end of the internal spline shaft, and the retainer is engaged with one end of the movable rod.

[0011] Preferably, the flipping mechanism includes a first bevel gear rotatably connected within the support seat and driven by an external motor, and a second bevel gear located within the support seat and coaxially fixed with the triangular plate, wherein the second bevel gear and the first bevel gear mesh with each other.

[0012] Preferably, two outer shells are fixedly installed inside the cooling box, and the two outer shells correspond to two rectangular plates respectively. The diameter of the upper half of the outer shell is larger than that of the lower half.

[0013] Preferably, the outer shell surface is fixedly connected to a first pipe and a second pipe that communicate with the interior. A dust suction sleeve is fixedly installed at the free end of the first pipe, a one-way valve is fixedly installed on the first pipe, and a one-way valve is fixedly installed on the second pipe.

[0014] Preferably, an arc-shaped opening is provided on the side wall of the outer shell, and an arc-shaped door is engaged in the arc-shaped opening, with a dust collection box located inside the outer shell magnetically attached to the arc-shaped door.

[0015] The method of using the anode carbon block waste heat recovery cooling equipment includes the following steps: S1. Cooling operation: When both sets of triangular plates are in a circular state, the cooling mechanism can drive the movable rod to a horizontal state, so that the two sets of triangular plates are in an upright state. The cooling mechanism can also drive the two sets of triangular plates to move in opposite directions to hold the material on the rotating lifting platform. After the rotating lifting platform descends, it drives the triangular plates and the material to rotate so that the material can be cooled evenly by the water mist sprayed from the nozzle, preventing the existence of cooling dead zones, which could cause the carbon block to crack or even break due to excessive temperature difference. S2. Waste Heat Recovery: When both sets of triangular plates are in fan mode, the cooling mechanism can drive the movable rod to a vertical position, so that the two sets of triangular plates are in a horizontal position. The triangular plates are driven to move downwards into the upper part of the outer shell, allowing the triangular plates to rotate as fans in the upper part of the outer shell, thereby completing the preheating recovery of the equipment during the cooling operation and delivering hot air to the outside of the cooling box. At this time, one-way valve one and one-way valve two are in the closed state, which does not affect the use of the outer shell as a fan shell. At the same time, the dust collection box is also removed.

[0016] S3. Cleaning impurities: When both sets of triangular plates are in fan mode, the cooling mechanism can drive the movable rod to a horizontal state, so that the two sets of triangular plates are in an upright state. The cooling mechanism can also drive the two sets of triangular plates to move in opposite directions, so that the edges of the triangular plates are pressed against the material surface. At this time, driving the two sets of triangular plates to rotate can scrape off the impurities on the material surface, completing the cleaning work and effectively improving the overall applicability of the device. S4. Dust handling: When both sets of triangular plates are in a circular state, the cooling mechanism can drive the movable rod to a vertical state, so that the two sets of triangular plates are in a horizontal state. Drive the triangular plates to move downward into the lower half of the shell, so that the triangular plates act as piston plates and perform piston movement inside the shell, sucking the dust formed when cleaning the surface impurities of the material into the shell and collecting it into the dust collection box.

[0017] Compared with the prior art, the present invention provides a waste heat recovery cooling device for anode carbon blocks, which has the following beneficial effects: When both sets of triangular plates are in a circular state, the cooling mechanism can drive the movable rod to a horizontal state, so that the two sets of triangular plates are in an upright state. The cooling mechanism can also drive the two sets of triangular plates to move in opposite directions to hold the material on the rotating lifting platform. After the rotating lifting platform descends, it drives the triangular plates and the material to rotate so that the material can be cooled evenly by the water mist sprayed from the nozzle, preventing the existence of cooling dead zones, which could cause the carbon block to crack or even break due to excessive temperature difference. When both sets of triangular plates are in fan mode, the cooling mechanism can drive the movable rod to a vertical position, so that the two sets of triangular plates are in a horizontal position. The triangular plates are driven to move downwards into the upper part of the outer casing, allowing the triangular plates to rotate as fans within the upper part of the outer casing. This completes the preheating recovery during the cooling operation of the equipment and delivers hot air to the outside of the cooling box. At this time, one-way valve one and one-way valve two are in the closed state, which does not affect the use of the outer casing as a fan casing. At the same time, the dust collection box is also removed.

[0018] When both sets of triangular plates are in fan mode, the cooling mechanism can drive the movable rod to a horizontal state, so that the two sets of triangular plates are in an upright state. The cooling mechanism can also drive the two sets of triangular plates to move in opposite directions, so that the edges of the triangular plates touch the material surface. At this time, driving the two sets of triangular plates to rotate can make the triangular plates scrape off the impurities on the material surface, complete the cleaning work, and effectively improve the overall applicability of the device. When both sets of triangular plates are in a circular state, the cooling mechanism can drive the movable rod to a vertical state, so that the two sets of triangular plates are in a horizontal state. The triangular plates are driven to move downward into the lower half of the outer shell, allowing the triangular plates to act as piston plates and perform piston motion inside the outer shell, sucking the dust formed when cleaning impurities on the surface of the material into the outer shell and collecting it into the dust collection box.

[0021] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example

[0022] like Figures 1-10 As shown, an embodiment of the present invention proposes a waste heat recovery cooling device for anode carbon blocks, including a cooling box 1. A nozzle 4 for spraying water for cooling is fixedly installed on the top surface of the inner wall of the cooling box 1. A rotating lifting platform 2 for carrying materials is fixedly installed on the bottom surface of the inner wall of the cooling box 1. A triangular plate 3 is provided inside the cooling box 1, as well as a cooling mechanism for driving the triangular plate 3.

[0023] The material carried on the rotary lifting platform 2 can be anode carbon blocks.

[0024] There are twelve triangle plates 3, arranged in groups of six. Each group of triangle plates 3 is arranged in a circular array. The two groups of triangle plates 3 are symmetrically distributed in the cooling box 1. There are also two cooling mechanisms, which correspond to the two groups of triangle plates 3 respectively.

[0025] Each set of triangular plates 3 is equipped with a flipping mechanism.

[0026] By setting a flipping mechanism, the triangle 3 can be controlled to rotate to different angles, allowing the triangle 3 to have two working states. One state is that the triangles 3 of the same group form a flat circular plate, such as... Figure 1 The state shown; Another type is where the same set of triangles 3 form a fan shape; When both sets of triangular plates 3 are in a circular state, the cooling mechanism can drive the movable rod 55 to a horizontal state, so that the two sets of triangular plates 3 are in an upright state. The cooling mechanism can also drive the two sets of triangular plates 3 to move in opposite directions to hold the material on the rotating lifting platform 2. After the rotating lifting platform 2 descends, it drives the triangular plates 3 and the material to rotate so that the material can be evenly cooled by the water mist sprayed from the nozzle 4, preventing the existence of cooling dead zones, which could cause the carbon block to crack or even break due to excessive temperature difference.

[0027] When both sets of triangular plates 3 are in fan mode, the cooling mechanism can drive the movable rod 55 to a horizontal state, so that the two sets of triangular plates 3 are in an upright state. The cooling mechanism can also drive the two sets of triangular plates 3 to move in opposite directions, so that the edges of the triangular plates 3 are pressed against the material surface. At this time, driving the two sets of triangular plates 3 to rotate can make the triangular plates 3 scrape off the impurities on the material surface, complete the cleaning work, and effectively improve the overall applicability of the device.

[0028] The cooling mechanism includes a horizontal plate 51 fixed to the side wall of the cooling box 1. A rectangular plate 52 is fixedly connected to the free end of the horizontal plate 51. A square track 53 is fixedly installed on the surface of the rectangular plate 52. There is a notch at one corner of the square track 53. A support seat 54 is rotatably connected to the rectangular plate 52 at the notch of the track 53. The support seat 54 is located at the intersection of the extended lines of the two ends of the track 53. A movable rod 55 that is telescopically connected to the support seat 54 passes through it.

[0029] A main shaft 56 driven by an external motor is rotatably connected to the surface of the rectangular plate 52. The main shaft 56 is located at the center inside the track 53. An insert rod 57, which is telescopically connected to the end of the main shaft 56 away from the rectangular plate 52, passes through it. A mounting base 58 is fixedly connected to the free end of the insert rod 57. A sliding column 59, which is rotatably connected to the mounting base 58, passes through it. One end of the sliding column 59 extends into the track 53 and slides with the track 53. A column 510 is rotatably connected to the other end of the sliding column 59. A movable rod 55 passes through the column 510 and is fixedly connected to the column 510.

[0030] When the main shaft 56 is driven to rotate by an external motor, the main shaft 56 can drive the insertion rod 57 to rotate accordingly. Since the free end of the insertion rod 57 is restricted by the mounting base 58 and the sliding column 59, it can only move along the track 53. Therefore, one end of the insertion rod 57 will extend and retract on the main shaft 56. At the same time, the column 510 can drive the movable rod 55 to rotate, and the movable rod 55 will also extend and retract with the support base 54 during the rotation. When the sliding column 59 is located inside the lower edge of the track 53, the movable rod 55 is in a horizontal state, such as... Figure 1 and Figure 2 As shown, the track 53 has two horizontal slots and two vertical slots. One of the vertical slots is located above the notch. When the sliding column 59 is located in it, the column 510 will push the movable rod 55 to a vertical position, so that the movable rod 55 is parallel to the vertical slot located above the notch.

[0031] One end of the movable rod 55 is fixedly connected to the bearing seat 511, and the triangular plate 3 is rotatably connected to the side wall of the bearing seat 511.

[0032] Among them, the bearing seat 511 is a regular hexagon, and a triangular plate 3 is rotatably connected to each of the six side walls of the bearing seat 511.

[0033] Two symmetrically distributed grooves 512 are provided at the end of the movable rod 55 away from the bearing seat 511. An L-plate 513 is fixedly connected to each of the two side walls of the rectangular plate 52. An external spline shaft 514 driven by a motor is rotatably connected to each L-plate 513. An internal spline shaft 515 adapted to the external spline shaft 514 is telescopically connected to it. A retainer 516 is fixedly connected to one end of the internal spline shaft 515. The retainer 516 is engaged and adapted to one end of the movable rod 55.

[0034] When the movable rod 55 rotates to a horizontal position, the end of the movable rod 55 will be engaged in a corresponding retainer 516. When the movable rod 55 rotates to a vertical position, the end of the movable rod 55 will be engaged in another corresponding slot 516; When the external spline shaft 514 is driven to rotate by the motor, the external spline shaft 514 can drive the movable rod 55 to rotate through the internal spline shaft 515 and the card holder 516. The movable rod 55 can drive the triangular plate 3 to rotate through the bearing seat 511. Once the movable rod 55 is engaged in the holder 516, it can move either closer to the holder 516 or further away from the holder 516, which will cause the holder 516 and the internal spline shaft 515 to move accordingly.

[0035] The flipping mechanism includes a bevel gear 61 rotatably connected within the support 511 and driven by an external motor, and a bevel gear 62 located within the support 511 and coaxially fixed with the triangular plate 3. The bevel gear 62 and the bevel gear 61 mesh with each other.

[0036] When the first bevel gear 61 is driven to rotate by the motor, it can drive the second bevel gear 62, which meshes with it, to rotate as well. The second bevel gear 62 can drive the triangular plate 3, which is fixed coaxially with it, to rotate to a preset angle.

[0037] Two outer shells 71 are fixedly installed inside the cooling box 1. The two outer shells 71 correspond to two rectangular plates 52 respectively. The diameter of the upper half of the outer shell 71 is larger than that of the lower half. Pipe 1 72 and pipe 2 76, which are connected to each other, are fixedly connected to the surface of the outer shell 71. A dust suction sleeve 74 is fixedly installed at the free end of pipe 1 72. A one-way valve 73 is fixedly installed on pipe 1 72. A one-way valve 77 is fixedly installed on pipe 2 76. An arc-shaped opening is opened on the side wall of the outer shell 71, and an arc-shaped door 78 is snapped into the arc-shaped opening. A dust collection box 79 located inside the outer shell 71 is magnetically attached to the arc-shaped door 78.

[0038] When both sets of triangular plates 3 are in a circular plate state, the cooling mechanism can drive the movable rod 55 to a vertical state, so that the two sets of triangular plates 3 are in a horizontal state, driving the triangular plates 3 to move downward into the lower half of the outer shell 71, allowing the triangular plates 3 to act as piston plates and perform piston movement inside the outer shell 71, sucking the dust formed when cleaning impurities on the surface of the material into the outer shell 71 and collecting it into the dust collection box 79. Gas containing dust and impurities enters the outer casing 71 through the dust suction sleeve 74 and pipe 1 72, and exits through pipe 2 76. Pipe 2 76 can be connected to an external hose to extend to the outside of the cooling box 1. When both sets of triangular plates 3 are in fan mode, the cooling mechanism can drive the movable rod 55 to a vertical state, so that the two sets of triangular plates 3 are in a horizontal state. The triangular plates 3 are driven to move downward into the upper part of the outer casing 71, so that the triangular plates 3 can rotate as fans in the upper part of the outer casing 71, thereby completing the preheating recovery of the equipment during the cooling operation and delivering the hot air to the outside of the cooling box 1. At this time, the one-way valve 73 and the one-way valve 77 are in the closed state, which does not affect the use of the outer casing 71 as a fan casing. At the same time, the dust collection box 79 is also removed.

[0039] Working principle: When bevel gear 61 is driven to rotate by the motor, it can drive bevel gear 62, which meshes with it, to rotate accordingly. Bevel gear 62 can drive triangular plate 3, which is fixed coaxially with it, to rotate to a preset angle. This allows the triangle 3 to have two working modes. One mode is where the triangles 3 in the same group form a flat circular plate, such as... Figure 1 The state shown; Another type is where the same set of triangles 3 form a fan shape; When the spindle 56 is driven to rotate by an external motor, the spindle 56 can drive the insertion rod 57 to rotate accordingly. Since the free end of the insertion rod 57 is restricted by the mounting base 58 and the sliding column 59, it can only move along the track 53. Therefore, one end of the insertion rod 57 will extend and retract on the spindle 56. At the same time, the column 510 can drive the movable rod 55 to rotate, and the movable rod 55 will also extend and retract with the support base 54 during the rotation. When the sliding column 59 is located inside the lower edge of the track 53, the movable rod 55 is in a horizontal state, such as... Figure 1 and Figure 2 As shown, the rotation of the insertion rod 57 can drive the movable rod 55 to move horizontally, allowing the movable rod 55 to drive the triangular plate 3 to move horizontally as well. The track 53 has two horizontal slots and two vertical slots. One of the vertical slots is located above the notch. When the sliding column 59 is inside it, the column 510 will push the movable rod 55 to a vertical position, so that the movable rod 55 is parallel to the vertical slot above the notch. As the insertion rod 57 rotates, it can drive the movable rod 55 to move in the vertical direction, so that the movable rod 55 can drive the triangular plate 3 to move in the vertical direction. When both sets of triangular plates 3 are in a circular state, the cooling mechanism can drive the movable rod 55 to a horizontal state, so that the two sets of triangular plates 3 are in an upright state. The cooling mechanism can also drive the two sets of triangular plates 3 to move in opposite directions to hold the material on the rotating lifting platform 2. After the rotating lifting platform 2 descends, it drives the triangular plates 3 and the material to rotate so that the material can be cooled evenly by the water mist sprayed from the nozzle 4, preventing the existence of cooling dead zones, which could cause the carbon block to crack or even break due to excessive temperature difference. When both sets of triangular plates 3 are in fan mode, the cooling mechanism can drive the movable rod 55 to a horizontal state, so that the two sets of triangular plates 3 are in an upright state. The cooling mechanism can also drive the two sets of triangular plates 3 to move in opposite directions, so that the edges of the triangular plates 3 are pressed against the material surface. At this time, driving the two sets of triangular plates 3 to rotate can scrape off the impurities on the material surface, complete the cleaning work, and effectively improve the overall applicability of the device. When both sets of triangular plates 3 are in a circular plate state, the cooling mechanism can drive the movable rod 55 to a vertical state, so that the two sets of triangular plates 3 are in a horizontal state, driving the triangular plates 3 to move downward into the lower half of the outer shell 71, allowing the triangular plates 3 to act as piston plates and perform piston movement inside the outer shell 71, sucking the dust formed when cleaning impurities on the surface of the material into the outer shell 71 and collecting it into the dust collection box 79. Gas containing dust and impurities enters the outer casing 71 through the dust suction sleeve 74 and pipe 1 72, and exits through pipe 2 76. Pipe 2 76 can be connected to an external hose to extend to the outside of the cooling box 1. When both sets of triangular plates 3 are in fan mode, the cooling mechanism can drive the movable rod 55 to a vertical state, so that the two sets of triangular plates 3 are in a horizontal state. The triangular plates 3 are driven to move downward into the upper part of the outer casing 71, so that the triangular plates 3 can rotate as fans in the upper part of the outer casing 71, thereby completing the preheating recovery of the equipment during the cooling operation and delivering the hot air to the outside of the cooling box 1. At this time, the one-way valve 73 and the one-way valve 77 are in the closed state, which does not affect the use of the outer casing 71 as a fan casing. At the same time, the dust collection box 79 is also removed.

The anode carbon block waste heat recovery cooling device according to claim 7, characterized in that, The outer shell (71) is fixedly connected to the surface of the outer shell (71) and the inner shell (72) and the inner shell (76) are connected to each other. The free end of the outer shell (72) is fixedly installed with a dust collection sleeve (74). The outer shell (72) is fixedly installed with a one-way valve (73) and the inner shell (76) is fixedly installed with a one-way valve (77).

9. The anode carbon block waste heat recovery cooling device according to claim 8, characterized in that, An arc-shaped opening is provided on the side wall of the outer shell (71), and an arc-shaped door (78) is engaged in the arc-shaped opening. A dust collection box (79) located inside the outer shell (71) is magnetically attached to the arc-shaped door (78).

10. Method of using the anode carbon block waste heat recovery cooling equipment according to claim 9, characterized in that, Includes the following steps: S1. Cooling operation: When both sets of triangular plates (3) are in the circular plate state, the cooling mechanism can drive the movable rod (55) to the horizontal state, so that the two sets of triangular plates (3) are in the upright state, and the cooling mechanism can drive the two sets of triangular plates (3) to move in the opposite direction to hold the material on the rotating lifting platform (2). After the rotating lifting platform (2) descends, it drives the triangular plates (3) and the material to rotate so that the material can be uniformly cooled by the water mist sprayed by the nozzle (4) to prevent the existence of cooling dead corners, which may cause the carbon block to crack or even break due to excessive temperature difference. S2, Waste heat recovery: When both sets of triangular plates (3) are in fan mode, the cooling mechanism can drive the movable rod (55) to a vertical state, so that the two sets of triangular plates (3) are in a horizontal state, drive the triangular plates (3) to move downward into the upper part of the outer shell (71), and let the triangular plates (3) rotate in the upper part of the outer shell (71) as a fan, thereby completing the preheating recovery of the equipment during the cooling operation, and delivering the hot air to the outside of the cooling box (1). At this time, the one-way valve one (73) and one-way valve two (77) are in the closed state, which does not affect the use of the outer shell (71) as a fan shell. At the same time, the dust collection box (79) is also removed. S3. Cleaning impurities: When both sets of triangular plates (3) are in fan mode, the cooling mechanism can drive the movable rod (55) to a horizontal state, so that the two sets of triangular plates (3) are in an upright state, and the cooling mechanism can drive the two sets of triangular plates (3) to move in opposite directions, so that the edge of the triangular plate (3) touches the material surface. At this time, driving the two sets of triangular plates (3) to rotate can make the triangular plates (3) scrape off the impurities on the material surface, complete the cleaning work, and effectively improve the overall applicability of the device. S4. Dust handling: When both sets of triangular plates (3) are in the circular plate state, the cooling mechanism can drive the movable rod (55) to the vertical state, so that the two sets of triangular plates (3) are in the horizontal state, drive the triangular plates (3) to move downward into the lower half of the outer shell (71), and let the triangular plates (3) act as piston plates to perform piston movement in the outer shell (71), sucking the dust formed when cleaning the surface impurities of the material into the outer shell (71) and collecting it into the dust collection box (79).
