Description

Technical Field

[0001] This invention relates to the field of bauxite clinker conveying, and more particularly to a conveyor for bauxite clinker. Background Technology

[0002] Bauxite clinker is a sintered product formed by calcining bauxite at high temperatures (usually 1200–1600℃). This process is called "calcination," and its purpose is to remove water of crystallization, improve the purity of alumina, and enhance the physicochemical properties of the material. The core characteristics of bauxite clinker are high hardness, high density, low porosity, excellent high temperature resistance, and corrosion resistance.

[0003] In existing technologies, bauxite clinker has a high hardness. When conveying bauxite clinker at heights, conveyor belts are mostly used. Whether the conveyor belt is made of soft metal or rubber, as the main load-bearing structure of bauxite clinker, it is prone to damage after long-term use. When replacing it, the equipment needs to be disassembled and a new conveyor belt needs to be replaced, which is time-consuming and labor-intensive. Moreover, when bauxite clinker needs to be conveyed at different heights, a height-matched conveyor is required, and the conveying height of the bauxite clinker conveyor cannot be flexibly adjusted as needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a conveyor for bauxite clinker to address the issue that existing bauxite clinker has high hardness, and when conveying bauxite clinker at heights, conveyor belts are mostly used. Whether the conveyor belt is made of soft metal or rubber, as the main load-bearing structure of bauxite clinker, it is prone to damage after long-term use. When replacing it, the equipment needs to be disassembled and a new conveyor belt needs to be replaced, which is time-consuming and labor-intensive. Furthermore, when bauxite clinker needs to be conveyed at different heights, a height-matched conveyor is required, and the conveying height of the bauxite clinker conveyor cannot be flexibly adjusted as needed.

[0005] To address the aforementioned problems, the present invention is implemented through the following technical solution.

[0006] A conveyor for bauxite clinker includes: a front base, a bearing frame welded and fixed to the upper end of the front base, a first rotating shaft arranged inside the bearing frame, a first rotating inner cylinder arranged outside the middle end of the first rotating shaft, transmission belts arranged at both ends of the outer side of the first rotating inner cylinder, a second rotating inner cylinder arranged inside the other end of the transmission belts, a second rotating shaft passing through the interior of the second rotating inner cylinder, a rotating shaft connected to one side of the second rotating shaft, a motor connected to one side of the rotating shaft, a connecting piece connected to one side of the transmission belt, a conveying plate stacked on the upper end of the connecting piece, multiple connecting bolts passing through the interior of the conveying plate and the connecting piece at equal intervals, and multiple conveying shovels arranged at equal intervals on the outer side of the conveying plate; The motor has a base frame welded and fixed to its bottom, and a telescopic rod is provided at the lower end of the base frame. A hydraulic rod is connected to the lower end of the telescopic rod, and a connecting plate is provided at the lower end of the hydraulic rod. A lockable bottom wheel is provided at the lower end of the connecting plate. A connecting seat is welded and fixed to one side of the base frame, and a first support frame is placed inside the connecting seat. A side baffle is connected to one side of the first support frame, and a second support frame is provided on the other side of the side baffle. A reinforcing plate is connected between the second support frame and the first support frame.

[0007] In one embodiment, two transmission belts are provided, and multiple reserved holes are provided through both transmission belts at equal intervals.

[0008] In one embodiment, multiple external toothed buckles are provided at equal intervals on the outer sides of the first and second rotating inner cylinders corresponding to the reserved holes of the transmission belt.

[0009] In one embodiment, multiple sets of reinforcing protrusions are provided at equal intervals on the outer side of the transmission belt, and the reinforcing protrusions are cylindrical.

[0010] In one embodiment, the conveying plate is connected to the connecting plate by connecting bolts to form a detachable structure.

[0011] In one embodiment, three bearing brackets are provided, with bearing brackets provided on both sides of the first rotating shaft and on the outer side of the second rotating shaft away from the motor.

[0012] In one embodiment, the telescopic rod, hydraulic rod, connecting plate, and lockable bottom wheel are provided in two sets. A bearing bracket is provided on the outer side of the end of the second rotating shaft away from the motor, and the other set of the telescopic rod, hydraulic rod, connecting plate, and lockable bottom wheel is provided at the lower end of the bearing bracket on one side of the second rotating shaft.

[0013] In one embodiment, a first mounting bolt is provided through the interior of the connecting seat and the first support frame, and a second mounting bolt is provided through the interior of the second support frame. The second mounting bolt passes through the second support frame and extends into the interior of the bearing frame. The second support frame and the first support frame form a detachable structure with the bearing frame and the connecting seat through the second mounting bolt and the first mounting bolt.

[0014] In one embodiment, the side cross-section of the conveying shovel has a T-shaped structure, and the cross-section at the bottom of the conveying shovel where it connects to the transmission belt is larger than the cross-section of the middle section of the conveying shovel.

[0015] This invention provides a conveyor for bauxite clinker. Compared with the prior art, it has the following advantages: When the conveyor plate is damaged during long-term material conveying, the connecting bolts between the conveyor plate and the connecting plate can be removed, and a new conveyor plate can be replaced by reconnecting it to the connecting plate using the connecting bolts. The conveyor plate mainly bears the weight of the bauxite clinker, and because bauxite clinker has high hardness, the conveyor plate is easily damaged. The conveyor plate is set up separately and is easy to replace without disassembling the equipment. When it is necessary to convey bauxite clinker at different heights, first rotate and remove the first and second mounting bolts, remove the first support frame, the second support frame, and the connected side baffle, and the bottom wheel can be unlocked and locked. Push the hydraulic rod forward or backward as needed (forward to lower the conveying height, backward to raise the conveying height). At the same time, the hydraulic rod is activated. Under the action of the hydraulic rod, the telescopic rod can retract to lower or extend to raise the base frame, lowering or raising the height reached by the upper end of the transmission belt. After adjusting the conveying height, lock the lockable bottom wheel at the lower end of the connecting plate. Then, match the side baffle with the corresponding slope and install it to continue stable use of the equipment. The structure of the conveyor can be quickly adjusted according to the conveying height, and it can convey bauxite clinker to equipment at different heights. Attached Figure Description

[0025] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0026] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] Reference Figures 1-8 A conveyor for bauxite clinker includes: a front base 1, a bearing frame 2 welded and fixed to the upper end of the front base 1, a first rotating shaft 3 arranged inside the bearing frame 2, a first rotating inner cylinder 4 arranged outside the middle end of the first rotating shaft 3, transmission belts 5 arranged at both ends of the outer side of the first rotating inner cylinder 4, a second rotating inner cylinder 11 arranged inside the other end of the transmission belt 5, a second rotating shaft 12 passing through the inside of the second rotating inner cylinder 11, a rotating shaft 13 connected to one side of the second rotating shaft 12, a motor 14 connected to one side of the rotating shaft 13, a connecting piece 8 connected to one side of the transmission belt 5, a conveying piece 9 stacked on the upper end of the connecting piece 8, a plurality of connecting bolts 10 passing through the conveying piece 9 and the connecting piece 8 at equal intervals, and a plurality of conveying shovels 27 arranged at equal intervals on the outer side of the conveying piece 9; A base frame 15 is welded and fixed to the bottom of the motor 14, and a telescopic rod 16 is provided at the lower end of the base frame 15. A hydraulic rod 17 is connected to the lower end of the telescopic rod 16. A connecting plate 18 is provided at the lower end of the hydraulic rod 17, and a lockable bottom wheel 19 is provided at the lower end of the connecting plate 18. A connecting seat 20 is welded and fixed to one side of the base frame 15. A first support frame 21 is placed inside the connecting seat 20. A side baffle 23 is connected to one side of the first support frame 21. A second support frame 24 is provided on the other side of the side baffle 23. A reinforcing plate 26 is connected between the second support frame 24 and the first support frame 21.

[0028] Two drive belts 5 are provided, and multiple reserved holes 6 are provided at equal intervals on both drive belts 5.

[0029] Multiple external toothed buckles 7 are provided at equal intervals on the outer sides of the first rotating inner cylinder 4 and the second rotating inner cylinder 11, corresponding to the reserved holes 6 of the transmission belt 5.

[0030] When the motor 14 is started, the rotating shaft 13 rotates. The rotation of the rotating shaft 13 drives the second rotating shaft 12 and the second rotating inner cylinder 11 to rotate. The second rotating inner cylinder 11 and its outer toothed buckle 7 rotate. The outer toothed buckle 7 continuously engages with the reserved hole 6 of the transmission belt 5. The rotation of the second rotating inner cylinder 11 drives the transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the first rotating inner cylinder 4 and the first rotating shaft 3 to rotate. Traditional single friction transmission is prone to slippage between the roller and the belt due to material impact, overload or changes in ambient temperature and humidity. This structure forms a mechanical forced guide through the rigid engagement of the outer toothed buckle 7 with the reserved hole 6. Even if the surface friction decreases, it can still maintain precise synchronous rotation and completely eliminate slippage. When the bauxite clinker clumps and causes a sudden surge in load, the toothed buckle engagement can instantly transmit torque and prevent the transmission belt 5 from spinning idly.

[0031] Multiple sets of reinforcing protrusions 28 are provided at equal intervals on the outer side of the transmission belt 5, and the reinforcing protrusions 28 are cylindrical.

[0032] The conveyor plate 9 is connected to the connecting plate 8 by the connecting bolt 10 to form a detachable structure.

[0033] When the conveyor plate 9 is damaged during long-term material conveying, the connecting bolt 10 connecting the conveyor plate 9 and the connecting plate 8 can be removed, and a new conveyor plate 9 can be replaced and reconnected to the connecting plate 8 through the connecting bolt 10. The conveyor plate 9 mainly bears the weight of bauxite clinker, and since bauxite clinker has high hardness, the conveyor plate 9 is easily damaged. The conveyor plate 9 is set up separately and is easy to replace, which can extend the overall service life of the conveyor for bauxite clinker.

[0034] There are three bearing brackets 2. The bearing brackets 2 are provided on both sides of the first rotating shaft 3 and on the outer side of the second rotating shaft 12 away from the motor 14.

[0035] Two sets of telescopic rods 16, hydraulic rods 17, connecting plates 18 and lockable bottom wheels 19 are provided. A bearing bracket 2 is provided on the outer side of the end of the second rotating shaft 12 away from the motor 14. The other set of telescopic rods 16, hydraulic rods 17, connecting plates 18 and lockable bottom wheels 19 is provided at the lower end of the bearing bracket 2 on one side of the second rotating shaft 12.

[0036] A first mounting bolt 22 is provided through the interior of the connecting seat 20 and the first support frame 21, and a second mounting bolt 25 is provided through the interior of the second support frame 24. The second mounting bolt 25 passes through the second support frame 24 and extends into the interior of the bearing frame 2. The second support frame 24 and the first support frame 21 form a detachable structure with the bearing frame 2 and the connecting seat 20 through the second mounting bolt 25 and the first mounting bolt 22.

[0037] The side cross-section of the conveying shovel 27 is T-shaped, and the cross-section at the bottom of the conveying shovel 27 where it connects with the transmission belt 5 is larger than the cross-section of the middle section of the conveying shovel 27.

[0038] When conveying bauxite clinker to different heights, first remove the first mounting bolt 22 and the second mounting bolt 25 by rotating them. Then, remove the first support frame 21, the second support frame 24, and the connected side baffle 23. The unlockable and lockable bottom wheel 19 can be unlocked. Push the hydraulic rod 17 forward or backward as needed (forward to lower the conveying height, backward to raise the conveying height). At the same time, activate the hydraulic rod 17. Under the action of the hydraulic rod 17, the telescopic rod 16 can retract to lower or extend to raise the base frame 15, thereby lowering or raising the height reached by the upper end of the transmission belt 5. After adjusting the conveying height, lock the lockable bottom wheel 19 at the lower end of the connecting plate 18. Then, install the side baffle 23 with the corresponding inclination to complete the installation and continue to use the equipment stably.

[0039] During use, motor 14 is first started, and the rotating shaft 13 of motor 14 rotates. The rotation of the rotating shaft 13 drives the second rotating shaft 12 and the second rotating inner cylinder 11 to rotate. The second rotating inner cylinder 11 and its outer toothed buckle 7 rotate, and the outer toothed buckle 7 continuously engages into the reserved hole 6 of the transmission belt 5. The rotation of the second rotating inner cylinder 11 drives the transmission belt 5 to rotate, and the rotation of the transmission belt 5 drives the first rotating inner cylinder 4 and the first rotating shaft 3 to rotate. In addition to the contact friction linkage, the outer toothed buckle 7 continuously engages into the reserved hole 6 of the transmission belt 5, achieving a dual linkage structure of friction drive and toothed buckle engagement. The structure is more stable, and the transmission belt 5 continuously... Rotation causes the inner connecting plate 8 and conveying plate 9 to rotate. The conveying plate 9 rotates continuously clockwise. The conveying shovel 27 on the outer side of the conveying plate 9 can scoop up the bauxite clinker at a lower position and transport it to a higher position for unloading. Side baffles 23 are provided on both sides of the conveying plate 9 to prevent the bauxite clinker from falling off the sides of the conveying shovel 27. The upper end of the conveying plate 9 is provided with multiple reinforcing protrusions 28, which can partially lift and support the high-hardness bauxite clinker. When the conveying plate 9 is damaged after long-term material transportation, the connecting bolts 10 connecting the conveying plate 9 and the connecting plate 8 can be removed and a new conveying plate 9 can be replaced by connecting the connecting bolts 10. Reconnect plate 8. When conveying bauxite clinker to different heights, first remove the first mounting bolt 22 and the second mounting bolt 25 by rotating. Remove the first support frame 21, the second support frame 24, and the connected side baffle 23. The bottom wheel 19 can be unlocked and locked. Push the hydraulic rod 17 forward or backward as needed (forward to lower the conveying height, backward to raise the conveying height). At the same time, activate the hydraulic rod 17. Under the action of the hydraulic rod 17, the telescopic rod 16 can retract to lower or extend to raise the base frame 15, lowering or raising the height reached by the upper end of the transmission belt 5. After adjusting the conveying height, lock the lower end of the connecting plate 18. The bottom wheel 19 can be locked. After that, the side baffle 23 with the corresponding slope is installed and the equipment can continue to be used stably. The first support frame 21 on the side of the side baffle 23 with the matching slope is placed on the upper end of the connecting seat 20. The first mounting bolt 22 is rotated and fixed inside the connecting seat 20 and the first support frame 21. Then, the second mounting bolt 25 is rotated and fixed inside the second support frame 24 and rotated into the bearing frame 2. The bearing frame 2 is fixed on the upper end of the front base 1. A reinforcing plate 26 is provided between the first support frame 21 and the second support frame 24 to increase the stability between the first support frame 21 and the second support frame 24.
