Description

Technical Field

[0001] This utility model relates to the field of installation and adjustment device technology, and in particular to an installation and adjustment device for a drum dryer. Background Technology

[0002] The drum dryer is a key piece of equipment in the pyrometallurgical calcination process of the RKEF (Rotary Kiln Electric Furnace) in submerged arc furnaces. Raw materials enter the kiln from the high end of the tail section for calcination. Due to the inclination and slow rotation of the kiln, the material undergoes a complex motion, both tumbling circumferentially and moving axially from the high end to the low end. The raw materials undergo decomposition, calcination, and cooling processes within the kiln, and are widely used in building materials, metallurgy, chemical, and cement industries for drying materials such as slag, limestone, pulverized coal, and clay. The drum dryer mainly consists of a rotating drum, a material throwing device, heat-resistant materials, a transmission device, a support device, sealing rings, and infeed / discharge devices.

[0003] However, existing drum dryers are mainly driven by a large gear ring mounted on the outside of the rotating drum. During the operation of the drum dryer, due to the high temperature inside the rotating drum, the drum may be pushed to move radially under the action of thermal expansion and contraction, resulting in the large gear ring and the drum not meeting the requirements for concentricity. Utility Model Content

[0004] The main purpose of this invention is to provide an installation and adjustment device for a drum dryer, which aims to avoid the problem that the large gear ring may be pushed during the operation of the drum dryer, causing the concentricity of the large gear ring and the drum body to fail to meet the requirements.

[0014] In one embodiment, the spring plate includes a first abutting plate, a second abutting plate, and an elastic portion, wherein the elastic portion is elastically connected between the first abutting plate and the second abutting plate;

[0015] The first abutment plate is used to fix the cylinder body, and the first abutment plate is arc-shaped to adapt to the outer shape of the cylinder body. The second abutment plate is fixedly connected to the large gear ring, and the second abutment plate is arc-shaped to adapt to the inner shape of the large gear ring.

[0016] In one embodiment, multiple support mechanisms are provided along the left-right direction, and the heights of the multiple support mechanisms vary in a stepped manner.

[0017] In one embodiment, the support mechanism further includes a plurality of inclined pads disposed between the roller support device and the first concrete foundation to adjust the inclination of the roller support device.

[0021] Four roller supports are located at both ends of the base in the left and right directions to support the drum dryer.

[0022] In one embodiment, there are three support mechanisms, which are arranged in the left-right direction as a first support mechanism, a second support mechanism and a third support mechanism. The first support mechanism is provided with a first base and a second base in the front-back direction. The second support mechanism is provided with a third base and a fourth base in the front-back direction. The third support mechanism is provided with a fifth base and a sixth base in the front-back direction.

[0029] In the technical solution of this utility model, multiple spring plates are provided between the large gear ring and the cylinder body. One end of each spring plate is elastically connected to the cylinder body, and the other end is elastically connected to the large gear ring. Therefore, during the operation of the cylinder dryer, if local overheating causes the cylinder body to expand, the spring plates will compress to make way for the expansion of the cylinder body. This avoids the problem that the large gear ring is squeezed during the expansion of the cylinder body, which would cause the concentricity between the large gear ring and the cylinder body to not meet the requirements.

[0044] The drum dryer is a key piece of equipment in the pyrometallurgical calcination process of the RKEF (Rotary Kiln Electric Furnace) in submerged arc furnaces. Raw materials enter the kiln from the high end of the tail section for calcination. Due to the inclination and slow rotation of the kiln, the material undergoes a complex motion, both tumbling circumferentially and moving axially from the high end to the low end. The raw materials undergo decomposition, calcination, and cooling processes within the kiln, and are widely used in building materials, metallurgy, chemical, and cement industries for drying materials such as slag, limestone, pulverized coal, and clay. The drum dryer mainly consists of a rotating drum, a material throwing device, heat-resistant materials, a transmission device, a support device, sealing rings, and infeed / discharge devices.

[0045] However, existing drum dryers are mainly driven by a large gear ring mounted on the outside of the rotating drum. During the operation of the drum dryer, due to the high temperature inside the rotating drum, the drum may be pushed to move radially under the action of thermal expansion and contraction, resulting in the large gear ring and the drum not meeting the requirements for concentricity.

[0046] This utility model proposes an installation and adjustment device 100 for a cylindrical dryer.

[0047] Please see Figure 1 In one embodiment of this utility model, the drum dryer includes a drum body 1, which includes multiple drum sections 11. The installation and adjustment device 100 of the drum dryer includes a support mechanism 2, a large gear ring 3, a drive mechanism 4, and multiple spring plates 5. The support mechanism 2 includes a first concrete foundation 21 and a roller support device 22. The roller support device 22 is disposed on the first concrete foundation 21 and is used to support and rotatably install the drum body 1. The large gear ring 3 is used to be sleeved on the periphery of the drum body 1 to drive the drum body 1 to rotate. The drive mechanism 4 is used to drive the rotation of the large gear ring 3. The multiple spring plates 5 are disposed on the inner side of the large gear ring 3 and distributed along the circumference of the large gear ring 3. One end of the spring plate 5 is elastically connected to the drum body 1, and the other end is elastically connected to the large gear ring 3.

[0048] In the technical solution of this utility model, multiple spring plates 5 are provided between the large gear ring 3 and the cylinder 1. One end of each spring plate 5 is elastically connected to the cylinder 1, and the other end is elastically connected to the large gear ring 3. Thus, during the operation of the cylinder dryer, if the cylinder 1 expands due to local overheating, the spring plates 5 will compress to make way for the expansion of the cylinder 1. This avoids the problem that the large gear ring 3 is squeezed during the expansion of the cylinder 1, which would cause the concentricity between the large gear ring 3 and the cylinder 1 to not meet the requirements.

[0049] It should be noted that this utility model does not limit the process of installing the large gear ring 3 into the drum dryer. Since the drum dryer is quite long, it is difficult to insert the large gear ring 3 from one side of the drum body 1 in actual operation. Therefore, in this embodiment, the large gear ring 3 includes an upper gear ring and a lower gear ring. During on-site assembly, a crane is used to insert the lower gear ring from the lower end of the drum body 1 and fix it at the set centerline position of the drum body 1. The adjusting frame is then spot-welded firmly to the drum body 1. Before unhooking, the lower gear ring is temporarily fixed in position using structural steel and sleepers at its lower part. Then, a crane is used to lift the upper gear ring from the drum body 1 to the corresponding position of the lower gear ring. The upper and lower gear rings are connected by positioning pins. A square and a measuring tape are used to initially measure the radial and axial runout of the large gear ring 3 relative to the drum body 1, and the tooling position of the large gear ring 3 is adjusted. After completion, each adjusting frame is welded to ensure firmness.

[0050] It should be noted that this utility model does not limit the specific method of adjusting the position of the tooling for the large gear ring 3. Please refer to [link / reference]. Figure 2In an embodiment of this utility model, the installation and adjustment device 100 of the drum dryer further includes a large gear ring adjustment mechanism 6. The large gear ring adjustment mechanism 6 includes a mounting base 61, a radial adjusting bolt 62, and two axial adjusting bolts 63. The mounting base 61 is fixedly disposed below the large gear ring 3. The radial adjusting bolt 62 is movably mounted on the mounting base 61 along the radial direction of the large gear ring 3 and abuts against the large gear ring 3 to drive the large gear ring 3 to move radially. The two axial adjusting bolts 63 are movably mounted on the mounting base 61 along the axial direction of the large gear ring 3 and abut against the large gear ring 3. The two axial adjusting bolts 63 are installed opposite each other to drive the large gear ring 3 to move axially. Specifically, when it is necessary to adjust the radial position of the large gear ring 3, simply rotate the radial adjusting bolt 62 so that the radial adjusting bolt 62 can drive the large gear ring 3 to move radially. When it is necessary to adjust the axial position of the large gear ring 3, simply rotate the corresponding axial adjusting bolt 63 to adjust the axial deviation of the large gear ring 3.

[0051] After the adjustment is completed, the positions of the large gear ring 3 and the cylinder 1 are initially corrected. This utility model does not limit the subsequent further correction steps. Specifically, in the embodiment of this utility model, the further correction step requires engaging the drive mechanism 4 and the large gear ring 3, and driving the rotation of the large gear ring 3 to drive the rotation of the cylinder 1. During the rotation of the cylinder 1, the radial and end face runout of the large gear ring 3 is measured to see if they meet the requirements. If they do not meet the requirements, the position of the spring plate 5 needs to be further adjusted according to the site conditions or the large gear ring 3 needs to be adjusted according to the steps in the above embodiment. If they meet the requirements, the spring plate 5 is fixedly connected between the large gear ring 3 and the cylinder 1, and the temporary fixing devices such as the adjustment frame are removed to complete the final installation of the large gear ring 3.

[0052] It should be noted that this utility model does not limit the structure or specific number of the spring plates 5. Please refer to [link / reference]. Figure 3 In an embodiment of this utility model, the spring plate 5 includes a first abutting plate 51, a second abutting plate 52, and an elastic part 53. The elastic part 53 is elastically connected between the first abutting plate 51 and the second abutting plate 52. The first abutting plate 51 is used to fixably connect to the cylinder 1, and the first abutting plate 51 is arc-shaped to adapt to the outer shape of the cylinder 1. The second abutting plate 52 is fixedly connected to the large gear ring 3, and the second abutting plate 52 is arc-shaped to adapt to the inner shape of the large gear ring 3. That is, by setting the first abutting plate 51 and the second abutting plate 52 to be arc-shaped to correspond to the shapes of the cylinder 1 and the large gear ring 3, this utility model increases the mating area and thus strengthens the connection strength of the spring plate 5.

[0053] Please see Figure 1 and Figure 5 In this embodiment of the invention, multiple support mechanisms 2 are provided along the left-right direction, and the heights of the multiple support mechanisms 2 vary in a stepped manner. Specifically, the height of the support mechanisms 2 decreases sequentially from left to right, thereby causing the drum dryer mounted on the support mechanisms 2 to be tilted, allowing the material inside the drum dryer to move more smoothly.

[0054] Since the support mechanism 2 is located on the first concrete foundation 21, and the upper surface of the first concrete foundation 21 is typically a plane, in order to make the force on the roller support device 22 more even, in this embodiment of the invention, the support mechanism 2 further includes multiple inclined pads. These inclined pads are positioned between the roller support device 22 and the first concrete foundation 21 to adjust the inclination of the roller support device 22. By using the inclined pads, the roller support device 22 is also inclined at the same angle as the cylinder 1, thereby making the force on each part of the roller support device 22 more even and the overall structure more stable. It should be noted that this invention does not limit the specific form of the inclined pads. In this embodiment, the inclined pads are inclined shims, welded between the first concrete foundation 21 and the roller support device 22. Specifically, shims are placed on both sides of each anchor bolt, and the remaining shims are placed on the reinforcing ribs of the roller support device 22. The distance between two adjacent sets of shims should not exceed 500mm. Each set of shims should not exceed four pieces, with the thickest one placed at the bottom and the thinnest one in the middle. The distance from which flat shims protrude from the roller support device 22 should be 10-40mm, and the distance from which inclined shims protrude from the roller support device 22 should be 10-50mm. The shims should fit tightly together and with the roller support device 22, with a contact area of ​​not less than 70% of the contact surface, and there should be no looseness. The length of the shim set extending into the bottom surface of the roller support device 22 should exceed the anchor bolt hole.

[0055] Please see Figure 4 and Figure 5 In an embodiment of this utility model, the support mechanism 2 further includes a base, and each support mechanism 2 includes a first concrete foundation 21, two bases, and four roller devices 22; wherein, the two bases are symmetrically arranged on the upper surface of the first concrete foundation 21 in the front-rear direction; the four roller devices 22 are respectively arranged at both ends of the base in the left-right direction to support the drum dryer. By providing two opposing sets of roller devices 22 in each support mechanism 2 to simultaneously support the drum dryer, the load-bearing capacity is improved and the stability of the equipment is enhanced.

[0056] In an embodiment of this utility model, there are three support mechanisms 2, arranged sequentially as a first support mechanism, a second support mechanism, and a third support mechanism in the left-right direction. The first support mechanism has a first base 231 and a second base 232 in the front-back direction; the second support mechanism has a third base 233 and a fourth base 234 in the front-back direction; and the third support mechanism has a fifth base 235 and a sixth base 236 in the front-back direction. The distance between the first base 231 and the third base 233 in the left-right direction is L1; the distance between the second base 232 and the fourth base 234 in the left-right direction is L2; ​​the distance between the third base 233 and the fifth base 235 in the left-right direction is L3; and the distance between the fourth base 234 and the sixth base 236 in the left-right direction is L4. The horizontal distance between the first base 231 and the fourth base 234 is L5, the horizontal distance between the fourth base 234 and the fifth base 235 is L7, the horizontal distance between the third base 233 and the sixth base 236 is L8, the distance between the first base 231 and the second base 232 in the front-back direction is B1, and the distance between the third base 233 and the fourth base 234 is L5. The distance between the fifth base 235 and the sixth base 236 in the front-back direction is B2, and the distance between them in the front-back direction is B3; wherein |L1-L2| ≤ 0.5mm, |L3-L4| ≤ 0.5mm, |L5-L6| ≤ 1mm, |L7-L8| ≤ 1mm, |B1-B2| ≤ 0.5mm, |B1-B3| ≤ 0.5mm, and |B3-B2| ≤ 0.5mm. In other words, by limiting the distances between adjacent bases in the front-back and horizontal directions, the axes of the three support mechanisms 2 in the horizontal direction are ensured to meet the requirements, thereby aligning the axis of the drum dryer and ensuring the stability of the equipment during operation.

[0057] Please see Figure 5 In this embodiment of the invention, the heights of the first base 231 and the second base 232 are both H1, the heights of the third base 233 and the fourth base 234 are both H2, and the heights of the fifth base 235 and the sixth base 236 are both H3; where (H2-H1) / L1=(H3-H2) / L3=(H3-H1) / L1+L3=tanA, and A is the design angle. That is, by measuring and calculating the angles between the three support mechanisms 2, the three support mechanisms 2 are ensured to be located on the same inclined plane, thereby making the drum dryer rotating on the three support mechanisms 2 more stable. It should be noted that this invention does not limit the specific value of the design angle A and can be adjusted according to actual needs.

[0058] Since the drum dryer includes multiple drum sections 11, in order to ensure that the multiple drum sections 11 are located on the same axis, please refer to [reference needed]. Figure 6 and Figure 7 In an embodiment of this utility model, the installation and adjustment device of the cylindrical dryer further includes a laser emitter 7, which emits a laser beam that passes through the central axis of the multiple cylindrical sections 11. Specifically, the centers of the multiple cylindrical sections 11 are provided with through holes for the laser beam to pass through. During the adjustment process, it is only necessary to ensure that the laser emitted by the laser emitter 7 is aligned with the centers of the first and last cylindrical sections 11. When adjusting other cylindrical sections 11, coordinate paper 8 is simply installed at the through holes so that the laser beam leaves corresponding coordinates on the coordinate paper 8. Then, the position of the cylindrical section 11 is adjusted according to the position of the coordinates until the laser beam hits the center of the coordinate paper 8, at which point the position adjustment of the cylindrical section 11 is complete. For example, if the laser beam hits the upper left corner of the coordinate paper 8, the cylindrical body 1 needs to be moved to the upper left until the laser beam hits the center of the coordinate paper 8.

[0059] During the installation of the drum dryer, the drive mechanism 4 needs to be temporarily fixed. Therefore, in this embodiment of the invention, the drive mechanism 4 includes a second concrete foundation and an embedded plate. The embedded plate is fixedly installed on the second concrete foundation, and the drive mechanism 4 is welded to the embedded plate. Specifically, by temporarily fixing the drive mechanism 4 by welding it to the embedded plate, disassembly is only required by removing the fixing device on the corresponding embedded plate, which is convenient.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
