Description

Technical Field

[0001] The present invention relates to the field of steel slag transportation, and in particular to steel slag transportation equipment. Background Art

[0002] Steel slag is primarily derived from oxides formed by the oxidation of elements contained in molten iron and scrap steel. During the steel production process, steel slag typically undergoes secondary processing. This significant process not only maximizes the resource utilization of steel slag, effectively reducing the land resources occupied by slag storage, but also significantly reduces environmental pollution and greatly improves the utilization rate of steel industry waste, achieving both economic and environmental benefits.

[0003] Among the many steps in the secondary processing of steel slag, slag transportation is particularly critical. However, traditional slag transportation methods are often limited to "point-to-point transportation." In this transportation model, the slag cannot receive additional processing during transportation and must wait until transportation is complete before being processed by subsequent equipment. This wastes transportation time and results in inefficient use of resources.

[0004] Furthermore, when conveying slag on traditional belt conveyors, the slag comes into direct contact with the conveying surface. When discharged from the steelmaking furnace, the slag typically reaches temperatures of around 1500°C to 1600°C. After initial cooling, the slag typically remains at temperatures of 200°C to 600°C when conveyed by belt conveyors. This is because slag has a large specific heat capacity and dissipates heat relatively slowly. Such high temperatures not only accelerate the aging and damage of the belt, shortening its service life, but can also cause safety hazards such as smoke and even fire.

[0005] In recent years, intelligent overhead conveying has gradually emerged as an advanced automated transportation system. It utilizes overhead tracks to suspend carriers such as hoppers and pallets, enabling the recirculation of materials. These tracks are often designed as closed tracks, such as elliptical or circular, with motors driving the carriers along pre-set paths. This system automatically handles material handling at various workstations, including feeding, sorting, and unloading. It offers significant advantages, including high space utilization, flexible scheduling, and a high degree of automation. It has been widely adopted in numerous fields, including automotive manufacturing and food processing.

[0006] Given the many advantages of intelligent suspension conveying systems, their application in the field of slag conveying is expected to significantly improve slag conveying efficiency and effectively save floor space. Therefore, it is particularly urgent to develop a new type of slag conveying equipment to better meet current production needs. Summary of the Invention

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figures 1 to 16 : A steel slag conveying device, comprising a frame 1 and a hanging track 2 arranged on the frame 1, further comprising a plurality of hanging support plates 3 arranged at equal intervals on the hanging track 2, a supporting plate 4 fixedly arranged on each hanging support plate 3 in a symmetrical state, a storage barrel 5 fixedly arranged between the two supporting plates 4, a cooling mechanism for cooling the steel slag inside the storage barrel 5, a blocking mechanism for controlling the release of materials from the storage barrel 5, and a screening mechanism for screening the steel slag. A discharge port 37 for feeding the steel slag is provided on the side of the frame 1, a feed port 6 and a discharge port 26 are provided at the top and bottom of the storage barrel 5, respectively, and each storage barrel 5 is provided with a There is a cooling mechanism, which includes a wind wheel 38 coaxially arranged on the outer wall of the storage barrel 5 and a rotating output end for driving the wind wheel 38 to rotate. A sealing mechanism is provided at each discharge port 26, and the sealing mechanism has a sealing output end for controlling the opening and closing of the discharge port 26. The screening mechanism includes a screening frame 47 fixedly arranged on the side of the frame 1 away from the discharge port 37, a first sieve plate 50 and a second sieve plate 52 arranged on the screening frame 47 from top to bottom, a storage frame 61 arranged below the second sieve plate 52, a first conveyor belt 51 arranged at the bottom end of the first sieve plate 50, and a second conveyor belt 53 arranged at the bottom end of the second sieve plate 52.

[0025] It should be noted that the steel slag discharged from the discharge port 37 is steel slag that has been initially cooled to 200-600 degrees. Position sensors are provided at the discharge port 37 and the feed port 6, that is, during the circulation movement of the storage barrel 5, the steel slag is discharged once through one storage barrel 5 from the discharge port 37. In addition, the hanging track 2 is a mature existing technology, so it will not be described in detail here. It can be started and stopped intermittently to cooperate with the above-mentioned transportation work. When the device is in operation, steel slag is fed from the discharge port 37 to the feed port 6, and then the hanging track 2 moves with the lifting support plate 3, causing the storage barrel 5 loaded with steel slag to start moving. After that, the cooling mechanism starts to operate, and the rotating output end drives the wind wheel 38 to rotate. The rotation of the wind wheel 38 generates wind force, which accelerates the heat removal from the storage barrel 5, and then cools the steel slag in the storage barrel 5. Wait for the storage barrel 5 to move to the screening frame 47, and the blocking mechanism opens the discharge port 26. At this time, the steel slag has been cooled, and the steel slag falls onto the first screen plate 50. Then, under the screening of the first screen plate 50 and the second screen plate 52, the larger particles of steel slag are sent away by the first conveyor belt 51, the medium particles of steel slag are sent away by the second conveyor belt 53, and the smaller steel slag particles fall from the second screen plate 52 into the storage frame 61. Screening in this way is convenient for subsequent processing and use.

[0026] In order to show the detailed structure of the cooling mechanism, the following features are also set: The cooling mechanism also includes a support plate 40 symmetrically fixed on the supporting plate 4 located above, a gearbox 41 fixedly connected to the two support plates 40, a first gear 42 coaxially fixed on the power input shaft of the gearbox 41, a power gear 43 coaxially fixed on the acceleration output shaft of the gearbox 41 and a power ring gear 44 coaxially fixed on the wind wheel 38. A first rack 39 is fixed on one side of the frame 1 close to the discharge port 37. The first rack 39 is used to engage the first gear 42, and the power gear 43 engages with the power ring gear 44. The power ring gear 44 is the rotating output end of the cooling mechanism.

[0027] When the device is running, the first gear 42 is engaged with the first rack 39. The rotation of the first gear 42 drives the power gear 43 to rotate through the acceleration of the gearbox 41. The rotation of the power gear 43 drives the power ring gear 44 to rotate. The power ring gear 44 drives the wind wheel 38 to rotate. The wind wheel 38 rotates to generate wind flow, which continuously takes away the heat on the storage barrel 5, thereby achieving cooling treatment of the steel slag.

[0028] In order to prevent uneven cooling of the slag in the storage barrel 5, the following features are also provided: A support ring frame 45 and a disturbance curved rod 46 vertically arranged in the storage barrel 5 are coaxially fixed in each storage barrel 5. The bottom end of the disturbance curved rod 46 is rotatably connected to the support ring frame 45, and the top end of the disturbance curved rod 46 passes through the storage barrel 5 and is connected to the first gear 42 through a pulley.

[0029] When the device is running, the rotation of the first gear 42 also drives the disturbance crank arm 46 to rotate through the pulley. The rotation of the disturbance crank arm 46 continuously turns the steel slag, thereby ensuring that the steel slag in the storage barrel 5 can be continuously turned and heat is evenly dissipated, which is convenient for cooling. It should be noted that the rotation speed generated by the first gear 42 engaging the first rack 39 is relatively low, and the crank arm 46 is spiral. The purpose of its rotation is to spirally lift the steel slag. The steel slag is stirred in this way, not for crushing the steel slag. Therefore, the crank arm 46 does not bear much resistance when turning the steel slag.

[0030] In order to show the detailed structure of the blocking mechanism, the following features are also set: A funnel-shaped guide bottom cover 7 is provided at the bottom of the storage barrel 5, and a discharge port 26 is opened at the center of the guide bottom cover 7. The blocking mechanism also includes a waist-shaped box 8 fixedly arranged at the bottom of the discharge port 26 and a blocking circular plate 10 slidably arranged in the waist-shaped box 8. A discharge port 9 is provided on the waist-shaped box 8, and the discharge port 9 is coaxial with the discharge port 26. The diameter of the blocking circular plate 10 is slightly larger than the diameter of the discharge port 9, and the blocking circular plate 10 is connected to the blocking output end.

[0031] When the discharge port 26 needs to be opened, the blocking output end drives the blocking circular plate 10 to open the discharge port 9, and then the slag can be discharged through the discharge port 9 and fall onto the first screen plate 50. In addition, the funnel shape of the guide bottom cover 7 facilitates the smooth discharge of the slag.

[0032] In order to show the detailed structure of the blocking mechanism blocking the output end, the following features are also set: The blocking mechanism also includes a U-shaped sliding frame 12 slidably set on the outer wall of the kidney-shaped box 8, a connecting rod 11 fixedly connected to the blocking circular plate 10, a touch rack 13 fixedly set on the U-shaped sliding frame 12, a limit support plate 14 fixedly set at the bottom of the kidney-shaped box 8, a touch shaft 15 rotatably set on the limit support plate 14, a second gear 16 coaxially fixedly set at the end of the touch shaft 15, a touch sleeve 17 coaxially fixedly set at the middle of the touch shaft 15 and a touch gear ring 19 transmission-connected to the touch sleeve 17, a second rack 48 for engaging the second gear 16 is fixedly set on the screening frame 47, the touch gear ring 19 is engaged with the touch rack 13, and the connecting rod 11 is fixedly connected to the U-shaped sliding frame 12.

[0033] The connecting rod 11 is the blocking output end of the blocking mechanism.

[0034] When the device is running, with the movement of the storage barrel 5, the second gear 16 engages with the second rack 48, and the rotation of the second gear 16 drives the touch shaft 15 to rotate. The rotation of the touch shaft 15 then drives the touch gear ring 19 to rotate through the touch sleeve 17. The touch gear ring 19 rotates and engages the touch rack 13, thereby causing the touch rack 13 to drive the U-shaped sliding frame 12 to move, and then the U-shaped sliding frame 12 drives the sealing circular plate 10 to open the material opening 9 through the connecting rod 11.

[0035] In order to prevent the second gear 16 from still meshing with the second rack 48 after the blocking circular plate 10 opens the feed opening 9, thereby damaging the equipment, the following features are specifically provided: The trigger sleeve 17 is provided with a plurality of elastic columns 18 at equal intervals in a circular pattern. The inner wall of the trigger tooth ring 19 is provided with a plurality of limiting grooves 20 at equal intervals in a circular pattern. A carrier box 22 is fixedly provided at the bottom of the waist-shaped box 8, and a coil spring 23 is provided in the carrier box 22. One end of the coil spring 23 is fixedly connected to the trigger shaft 15, and the other end is fixedly connected to the inner wall of the carrier box 22. The trigger shaft 15 is rotatably connected to the carrier box 22. A guide slope 21 is provided on one side of the limiting groove 20. The column head of the elastic column 18 is stuck in the limiting groove 20 under the action of elasticity.

[0036] When the touch shaft 15 rotates, the rotation of the touch shaft 15 drives the touch sleeve 17 to rotate, and the rotation of the touch sleeve 17 drives all the elastic columns 18 to rotate. The elastic columns 18 then drive the touch gear ring 19 to rotate synchronously through the column heads stuck in the limit grooves 20, waiting for the discharge port 9 to be fully opened. At this time, the touch sleeve 17 continues to rotate, but the touch gear ring 19 has moved to the extreme position of the touch rack 13. Therefore, at this time, the touch gear ring 19 is in a fixed state relative to the touch sleeve 17. As the touch sleeve 17 rotates, the elastic column 18 resists the guide inclined surface 21, and then the column head of the elastic column 18 retracts, and "slipping" occurs between the touch sleeve 17 and the touch gear ring 19, thereby ensuring that the equipment can continue to operate normally after the discharge port 9 is opened, giving the equipment a little fault tolerance to prevent the discharge port 9 from being opened but the second gear 16 has not passed the length of the second rack 48, thereby avoiding jamming and causing damage to the equipment.

[0037] In order to ensure that the slag falling from the discharge port 26 can be evenly spread on the first screen plate 50, the following features are specifically provided: A material-laying square tube 24 is fixedly provided at the bottom of each kidney-shaped box 8 , a material-laying square tube 24 is fixedly provided with a material-blocking piece 25 , and the material-laying square tube 24 is arranged below the discharge port 9 .

[0038] During the rotation of the touch shaft 15, the rotation of the touch shaft 15 always applies torque to the coil spring 23. After the second gear 16 passes the second rack 48, the coil spring 23 releases the torque to drive the touch shaft 15 to rotate in the opposite direction. The reverse rotation of the touch shaft 15 drives the touch sleeve 17 to rotate in the opposite direction. Since a guide slope 21 is provided at the limit groove 20, when the touch sleeve 17 starts to rotate in the opposite direction, the elastic column 18 will slide into the guide slope 21 and then get stuck in the limit groove 20. Then the touch sleeve 17 drives the touch gear ring 19 to rotate in the opposite direction. The reverse rotation of the touch gear ring 19 engages the touch rack 13 to move, and then drives the sealing circular plate 10 to block the discharge port 9 through the U-shaped sliding frame 12 and the connecting rod 11. In addition, the setting of the blocking piece 25 can disperse the steel slag, so that it is evenly spread on the first screen plate 50.

[0039] In order to prevent slag from accumulating on the guide bottom cover 7, the following features are also provided: Each lifting support plate 3 is provided with a knocking mechanism, which includes a mounting plate 28 fixedly set on the bearing plate 4, a limiting sleeve 29 fixedly set on the mounting plate 28, a bearing shaft 30 rotatably set in the limiting sleeve 29 by a torsion spring, a knocking rod 31 fixedly set on the bearing shaft 30, a toggle crank rod 32 with one end coaxially connected to the bearing shaft 30, a connecting shaft 33 rotatably set on the mounting plate 28, a toggle gear 34 coaxially fixed on the connecting shaft 33, a power shaft 35 rotatably set on the lifting support plate 3 and a third gear 36 coaxially fixed on the power shaft 35, a third rack 27 for meshing with the third gear 36 is fixedly set on the frame 1, and under the action of the torsion spring, the knocking rod 31 is always against the deflector bottom cover 7, and the other end of the toggle crank rod 32 is against the toggle gear 34.

[0040] It should be noted that when the second rack 48 is engaged with a second gear 16, the third rack 27 is also engaged with a third gear 36. When the device is running, the third gear 36 is engaged with the third rack 27. The rotation of the third gear 36 drives the power shaft 35 to rotate. The rotation of the power shaft 35 is transmitted through the bevel gear to drive the connecting shaft 33 to rotate. The rotation of the connecting shaft 33 drives the toggle gear 34 to rotate. The rotation of the toggle gear 34 continuously drives the toggle crank 32 to swing. The swing of the toggle crank 32 drives the bearing shaft 30 to rotate. The rotation of the bearing shaft 30 overcomes the torsion force of the torsion spring and drives the knocking rod 31 away from the diversion bottom cover 7. When a tooth of the toggle gear 34 passes one end of the toggle crank 32, the torsion spring releases the torsion force and drives the bearing shaft 30 to rotate in the opposite direction, thereby driving the knocking rod 31 to hit the diversion bottom cover 7. This reciprocating process can be used to reciprocately hit the diversion bottom cover 7 through the knocking rod 31 to form vibration, thereby preventing steel slag from accumulating.

[0041] In order to ensure that the first sieve plate 50 and the second sieve plate 52 have a better screening effect, the following features are specifically provided: The screening mechanism also includes two connecting cross plates 49 symmetrically arranged on the screening frame 47, an interfering ridge 54 fixedly arranged on the connecting cross plate 49 close to the frame 1, a toggle chain 59 arranged at the bottom end of the frame 1, a bearing cross plate 55 fixedly arranged on the screening frame 47, a toggle shaft 56 rotatably arranged on the bearing cross plate 55, a cam 58 coaxially fixedly arranged at one end of the toggle shaft 56 and a toggle gear 34 at the other end, the cam 58 is in contact with the interfering ridge 54, and a lifting rod 60 is fixedly arranged at the bottom of each lifting support plate 3, all lifting rods 60 are fixedly connected to the toggle chain 59, and the toggle chain 59 is engaged with the vibration gear 57.

[0042] When the device is running, the lifting support plate 3 drives the lifting rod 60 to rotate, and then drives the toggle chain 59 to rotate continuously. The rotation of the toggle chain 59 engages with the vibration gear 57, which makes the vibration gear 57 rotate. The rotation of the vibration gear 57 drives the toggle shaft 56 to rotate. The rotation of the toggle shaft 56 drives the cam 58 to rotate. The rotation of the cam 58 continuously touches the friction convex strip 54, which makes the connecting cross plate 49 shake up and down on the screening frame 47, thereby making the first screen plate 50 and the second screen plate 52 vibrate, thereby enhancing the screening effect.

[0043] The working principle of this device is as follows: when the slag conveying equipment is in operation, the slag that has been initially cooled to 200-600 degrees is fed into the feed port 6 of the storage bucket 5 from the discharge port 37, and the suspension track 2 drives the hoisting support plate 3 and the storage bucket 5 to move.

[0044] During this movement, a first rack 39 on the frame 1 near the discharge port 37 meshes with a first gear 42 on the power input shaft of the gearbox 41 in the cooling mechanism, driving the power gear 43 to rotate. This, in turn, causes the power ring gear 44 to rotate the wind wheel 38, generating airflow that cools the slag in the storage barrel 5. Simultaneously, the first gear 42, via a pulley, rotates a disturbance crank 46 inside the storage barrel 5, stirring the slag to ensure uniform cooling.

[0045] When the storage barrel 5 moves to the screening frame 47, the second rack 48 on the screening frame 47 engages with the second gear 16 at the end of the trigger shaft 15 rotatably set on the limit support plate 14 in the blocking mechanism, driving the trigger shaft 15 to rotate, and the trigger gear ring 19 rotates through the trigger sleeve 17. The trigger gear ring 19 engages with the trigger rack 13, driving the U-shaped sliding frame and the connecting rod 11, so that the blocking circular plate 10 opens the discharge port 26, and the steel slag falls onto the first screen plate 50 through the guide bottom cover 7 and the discharge port 9.

[0046] At this time, the third gear 36 which moves synchronously with the second gear 16 is engaged with the third rack 27 on the frame 1, driving the power shaft 35 to rotate, and the bevel gear transmission causes the toggle gear 34 on the connecting shaft 33 to rotate, and the toggle crank rod 32 drives the knock rod 31 to hit the guide bottom cover 7 to prevent slag accumulation.

[0047] The slag is screened on the first and second screen plates 50, 52. Larger particles are conveyed away by the first conveyor belt 51, medium particles are conveyed away by the second conveyor belt 53, and smaller particles fall into the storage frame 61. Simultaneously, the hoisting support plate 3 drives the hoisting rod 60 to rotate the toggle chain 59, which engages with the toggle gear 34, driving the cam 58 to rotate and vibrate the connecting cross plate 49, thereby enhancing the screening effect of the first and second screen plates 50, 52.

[0048] After waiting for the slag to be emptied and the second gear 16 passes the length of the second rack 48, the coil spring 23 releases the torque to drive the touch shaft 15 to rotate in the opposite direction, and the reverse rotation of the touch shaft 15 drives the touch sleeve 17 to rotate in the opposite direction. Since a guide slope 21 is provided at the limit groove 20, when the touch sleeve 17 starts to rotate in the opposite direction, the elastic column 18 will slide into the guide slope 21 and then get stuck in the limit groove 20, and then the touch sleeve 17 drives the touch gear ring 19 to rotate in the opposite direction, and the touch gear ring 19 rotates in the opposite direction to engage the touch rack 13 to move, and then drives the sealing circular plate 10 to block the discharge port 9 through the U-shaped sliding frame 12 and the connecting rod 11.

[0049] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
