Description

Technical Field

[0001] The invention belongs to the technical field of metallurgy, and in particular relates to a follower rolling sweeping device for a friction plate of an annular cooler and an annular cooler. Background Art

[0002] In the metallurgical field, annular coolers are core equipment in the sintering and pelletizing processes, used to cool sintered ore produced by sintering machines and oxidized pellets after roasting in chain grate rotary kilns. Among the transmission types used in annular coolers, friction drive is the most widely used. Active and passive friction wheels clamp friction plates on a rotating frame. A drive mechanism rotates the active friction wheel, leveraging the friction between the active friction wheel and the friction plate to propel the plate and rotate the rotating frame. Therefore, before the friction plate and active friction wheel come into contact, the contact area must be clean. If particles become trapped between the friction plate and the active friction wheel, the contact surface will separate, reducing the friction force required to drive the friction plate and causing the active friction wheel to slip. However, during operation, especially during loading and unloading, dust and loose materials generated by the annular cooler can easily fall onto the friction plate, leading to particle entrainment between the friction plate and the active friction wheel. Summary of the Invention

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] In a first aspect, this embodiment provides a follower rolling sweep device for the friction plate of an annular cooler. Figure 1 This is a structural schematic diagram of a friction plate follower sweeping device for an annular cooler provided in this embodiment.

[0034] likeFigure 1 As shown, the annular cooler friction plate follower sweeping device of this embodiment includes: a friction wheel 1, a first-stage speed-increasing transmission assembly 2, a second-stage speed-increasing transmission assembly 3, and a roller brush 4. The friction wheel 1 can contact the side of the friction plate 6 and transmit the power through friction. The power input end of the first-stage speed-increasing transmission assembly 2 is transmission-connected to the friction wheel 1. The power input end of the second-stage speed-increasing transmission assembly 3 is transmission-connected to the power output end of the first-stage speed-increasing transmission assembly 2. The power output end of the second-stage speed-increasing transmission assembly 3 is transmission-connected to the roller brush 4. The roller brush 4 is located on the plate surface of the friction plate 6. The axial direction of the roller brush 4 is parallel to the plate surface of the friction plate 6, and the axial direction of the roller brush 4 forms an angle with the radial direction of the friction plate 6.

[0035] In this embodiment, in order to ensure that the roller brush 4 effectively cleans the surface of the friction plate 6, the rotation direction of the roller brush 4 is opposite to the rotation direction of the friction plate 6. Along the rotation direction of the friction plate 6, the roller brush 4 is located upstream of the active friction wheel.

[0036] The friction wheel 1 of this embodiment can be made of metal or non-metal (such as leather, rubber, wood, mixed fabric, etc.) as long as its friction coefficient can meet the use requirements. This embodiment does not impose too many restrictions on this.

[0037] The roller brush 4 of this embodiment has a rotating roller and bristles arranged on the side of the rotating roller along the circumference of the rotating roller. The bristles have a certain density and are in contact with the surface of the friction plate 6 to be able to clean the debris on the surface of the friction plate 6.

[0038] The circular cooler friction plate follower sweeping device of this embodiment comprises a friction wheel 1, a primary speed-increasing transmission assembly 2, a secondary speed-increasing transmission assembly 3, and a roller brush 4. The friction wheel 1 contacts the side of the friction plate 6 and transmits power through friction. The primary speed-increasing transmission assembly 2 and the secondary speed-increasing transmission assembly 3 transmit power to the roller brush 4, enabling rapid rotation of the roller brush 4. The roller brush 4 is positioned on the surface of the friction plate 6, with the axial direction of the roller brush 4 forming an angle with the radial direction of the friction plate 6. Rapid rotation of the roller brush 4 sweeps foreign matter from the friction plate 6 to the outside of the friction plate 6, achieving efficient cleaning of the friction plate 6. The circular cooler friction plate follower sweeping device of the present invention does not require an additional power source, thus conserving energy and reducing production costs.

[0039] Figure 2 This is a schematic diagram of the structure of a first-stage speed-increasing transmission component 2 and a second-stage speed-increasing transmission component 3 provided in this embodiment. In some embodiments, Figure 2 As shown, the first-stage speed-increasing transmission assembly 2 includes a first cylindrical gear 21 and a second cylindrical gear 22. The first cylindrical gear 21 is in driving connection with the friction wheel 1. The second cylindrical gear 22 meshes with the first cylindrical gear 21 for transmission. The diameter of the first cylindrical gear 21 is larger than the diameter of the second cylindrical gear 22.

[0040] In this embodiment, the diameter difference between the first cylindrical gear 21 and the second cylindrical gear 22 can be set according to actual usage requirements, and this embodiment does not impose too many restrictions on this.

[0041] The first-stage speed-increasing transmission assembly 2 of this embodiment includes a first cylindrical gear 21 and a second cylindrical gear 22, which mesh with the first cylindrical gear 21 for transmission. The first cylindrical gear 21 is in transmission connection with the friction wheel 1. Therefore, the first cylindrical gear 21 is the power input end of the first-stage speed-increasing transmission assembly 2, and the second cylindrical gear 22 is the power output end of the first-stage speed-increasing transmission assembly 2. The diameter of the first cylindrical gear 21 is larger than the diameter of the second cylindrical gear 22, which has a speed-increasing effect and increases the speed output of the power output end of the first-stage speed-increasing transmission assembly 2.

[0042] In some embodiments, as Figure 2 As shown, the first-stage speed-increasing transmission assembly 2 further includes a half-shaft 23 and a first bearing 24. One end of the half-shaft 23 is rotatably disposed in the first bearing 24. The first cylindrical gear 21 and the friction wheel 1 are disposed on the half-shaft 23, with the friction wheel 1 located at the end of the half-shaft 23 away from the first bearing 24.

[0043] In this embodiment, the friction wheel 1 and the first cylindrical gear 21 are driven by the half shaft 23 , which can effectively transmit the torque of the friction wheel 1 to the first cylindrical gear 21 .

[0044] The first-stage speed-increasing transmission assembly 2 of this embodiment also includes a half-shaft 23 and a first bearing 24. The first bearing 24 is fixedly arranged. The bottom end of the half-shaft 23 is rotatably arranged in the first bearing 24. The friction wheel 1 is fixed to the top of the half-shaft 23 and abuts against the side of the friction plate 6 to realize friction transmission. The first cylindrical gear 21 is arranged on the half-shaft 23 and fixed between the shoulder of the half-shaft 23 and the friction wheel 1. When the driving device drives the friction plate 6 to rotate, the friction plate 6 drives the friction wheel 1 to rotate. The friction wheel 1 drives the first cylindrical gear 21 through the half-shaft 23 to realize the power input of the first-stage speed-increasing transmission assembly 2.

[0045] In some embodiments, as Figure 2 As shown, the secondary speed-increasing transmission assembly 3 includes a first bevel gear 31 and a second bevel gear 32. The first bevel gear 31 is in driving connection with the power output end of the primary speed-increasing transmission assembly 2. The first bevel gear 31 meshes with the second bevel gear 32 for transmission. The diameter of the first bevel gear 31 is larger than the diameter of the second bevel gear 32.

[0046] In this embodiment, the diameter difference between the first bevel gear 31 and the second bevel gear 32 can be set according to actual usage requirements, and this embodiment does not impose too many restrictions on this.

[0047] The two-stage speed-increasing transmission assembly 3 of this embodiment includes a first bevel gear 31 and a second bevel gear 32. The first bevel gear 31 is in transmission connection with the power output end (i.e., the second cylindrical gear 22) of the one-stage speed-increasing transmission assembly 2. The first bevel gear 31 and the second bevel gear 32 are meshed for transmission. Therefore, the first bevel gear 31 is the power input end of the two-stage speed-increasing transmission assembly 3, and the second bevel gear 32 is the power output end of the two-stage speed-increasing transmission assembly 3. The diameter of the first bevel gear 31 is larger than the diameter of the second bevel gear 32, which has the effect of increasing speed and improving the speed output of the power output end of the two-stage speed-increasing transmission assembly 3. In addition, the first bevel gear 31 and the second bevel gear 32 are used to transmit the speed and torque of the two-stage speed-increasing transmission assembly 3, which not only has the effect of increasing speed again, but also realizes vertical redirection, so that the roller brush 4 can fit on the friction plate 6.

[0048] In some embodiments, as Figure 2 As shown, the secondary speed-increasing transmission assembly 3 further includes a through shaft 33, a second bearing 34, and a third bearing 35. The through shaft 33 is rotatably disposed between the second bearing 34 and the third bearing 35. The first bevel gear 31 is connected to the power output end of the primary speed-increasing transmission assembly 2 via the through shaft 33.

[0049] The two-stage speed-increasing transmission assembly 3 of this embodiment also includes a through shaft 33, a second bearing 34, and a third bearing 35. The second and third bearings 34, 35 support the through shaft 33. The through shaft 33 is rotatably disposed between the second and third bearings 34, 35, with the axis of the through shaft 33 parallel to the axle shaft 23. The first bevel gear 31 is connected to the power output end of the first-stage speed-increasing transmission assembly 2 (i.e., the second cylindrical gear 22) via the through shaft 33. When the drive device rotates the friction plate 6, the friction plate 6 drives the friction wheel 1 to rotate. The friction wheel 1 drives the first cylindrical gear 21 via the axle shaft 23, thereby inputting power to the first-stage speed-increasing transmission assembly 2. The meshing transmission between the first cylindrical gear 21 and the second cylindrical gear 22 achieves primary speed-increasing and torque transmission. The second cylindrical gear 22 drives the first bevel gear 31 via the through shaft 33, thereby inputting power to the two-stage speed-increasing transmission assembly 3. The meshing transmission between the first bevel gear 31 and the second bevel gear 32 achieves secondary speed-increasing, vertical redirection, and torque transmission. The roller brush 4 is transmission-connected to the second bevel gear 32 , so that the roller brush 4 rotates to sweep foreign matter on the friction plate 6 to the outside of the friction plate 6 .

[0050] In some embodiments, as Figure 2 As shown, a shaft sleeve 36 is provided on the through shaft 33. The shaft sleeve 36 is connected between the third bearing 35 and the first bevel gear 31.

[0051] In this embodiment, a shaft sleeve 36 is provided on the through shaft 33, which can fix the first bevel gear 31 between the shaft sleeve 36 and the shaft shoulder of the through shaft 33, thereby limiting the first bevel gear 31 and ensuring smooth transmission between the first bevel gear 31 and the second bevel gear 32.

[0052] Figure 3 for Figure 2 In some embodiments, as Figure 3 As shown, the two-stage speed-increasing transmission assembly 3 further includes a fourth bearing 37. The axis of the fourth bearing 37 is perpendicular to the surface of the friction plate 6. A tail shaft 321 is mounted on the second bevel gear 32. The second bevel gear 32 is rotatably mounted in the fourth bearing 37 via the tail shaft 321. The roller brush 4 is mounted on the tail shaft 321.

[0053] This embodiment utilizes the fourth bearing 37 to support the second bevel gear 32 and enables the second bevel gear 32 to rotate smoothly. It also provides reliable support for the rotation of the roller brush 4, ensuring that the roller brush 4 can effectively clean the plate surface of the friction plate 6.

[0054] In some embodiments, as Figure 3 As shown, a round nut 39 is provided on the tail shaft 321. The tail shaft 321 is fixedly connected to the inner ring of the fourth bearing 37 through the round nut 39.

[0055] In this embodiment, the tail shaft 321 is provided with external threads, and a round nut 39 is threadedly connected to the tail shaft 321. In this embodiment, the round nut 39 can also be used with a locking washer 38. During assembly, the inner tongue of the locking washer 38 is inserted into the groove on the tail shaft 321, while the outer tongue of the locking washer 38 is inserted into the groove of the round nut 39, thereby locking the tail shaft 321. This ensures a fixed connection between the tail shaft 321 and the inner ring of the fourth bearing 37, allowing them to rotate synchronously.

[0056] Figure 4 for Figure 1 A-direction schematic diagram. Figure 5 for Figure 1 Schematic diagram of direction B. Figure 6 for Figure 1 In some embodiments, as Figure 1 as well as Figures 4-6 As shown, the annular cooler friction plate follower sweeping device of this embodiment also includes a frame 5. The frame 5 includes: a shell 51, a top plate 52 and a fixed plate 53. The shell 51 is cylindrical. An opening is provided on the side wall of the shell 51. The opening passes through the side wall of the shell 51 along the axial direction of the shell 51. And the opening faces the friction plate 6. The top plate 52 is detachably arranged on the top of the shell 51. The fixed plate 53 is arranged below the top plate 52 and the edge of the fixed plate 53 is connected to the inner wall of the shell 51. The first-stage speed-increasing transmission assembly 2 and the second-stage speed-increasing transmission assembly 3 are arranged between the top plate 52 and the fixed plate 53.

[0057] In this embodiment, if Figure 2 As shown, a dual bearing seat 54 is provided on the fixed plate 53, and a single bearing seat 55 is provided on the top plate 52. The first bearing 24 and the second bearing 34 are disposed on the dual bearing seat 54. The third bearing 35 is disposed on the single bearing seat 55 and corresponds to the position of the second bearing 34. The bottom end of the half shaft 23 is disposed in the first bearing 24, the lower end of the through shaft 33 is disposed in the second bearing 34, and the upper end is disposed in the third bearing 35. A vertical bearing seat 56 is provided on the side of the top plate 52 near the opening, and the fourth bearing 37 is disposed in the vertical bearing seat 56 and positioned by an end cover 57. The tail shaft 321 is disposed in the fourth bearing 37 and connected to the roller brush 4.

[0058] In this embodiment, if Figures 4-6 As shown, the housing 51 is cylindrical. An opening is provided on the side wall of the housing 51. The opening penetrates the side wall of the housing 51 along the axial direction of the housing 51, so that the housing 51 is U-shaped when viewed from above, with the opening facing the friction plate 6.

[0059] The top plate 52 of this embodiment is detachably connected to the top of the housing 51 by bolts, which ensures the structural stability of the top plate 52 and facilitates disassembly and installation of various components below the top plate 52.

[0060] The annular cooler friction plate follower sweeping device of this embodiment further includes a frame 5. The frame 5 comprises a housing 51, a top plate 52, and a fixing plate 53. The frame 5, comprised of the housing 51, top plate 52, and fixing plate 53, provides support for the friction wheel 1, the primary speed-increasing transmission assembly 2, the secondary speed-increasing transmission assembly 3, and the roller brush 4. This improves the integrity of the annular cooler friction plate follower sweeping device and facilitates its overall installation on the annular cooler.

[0061] Secondly, this embodiment further provides an annular cooler, comprising: an annular cooler body and the aforementioned annular cooler friction plate follower sweeping device. The annular cooler body comprises: a drive device, an active friction wheel, a passive friction wheel, a revolving frame 7, and a friction plate 6. The friction plate 6 is connected to the revolving frame 7. The active friction wheel and the passive friction wheel clamp the friction plate 6. The drive device drives the active friction wheel to rotate, utilizing the friction force between the active friction wheel and the friction plate 6 to drive the friction plate 6 to rotate, thereby driving the revolving frame 7 to rotate. The annular cooler friction plate follower sweeping device is used to remove foreign matter from the friction plate 6.

[0062] The ring cooler of this embodiment also includes a trolley, a feeding device, a discharge device, an air blast system, a sealing device, and components such as a ring cooler frame, a support roller mechanism, side rollers, a pressure rail, a bellows, and an ash discharge valve. The ring cooler body is equipped with several fan-shaped trolleys connected to a horizontally arranged revolving frame 7, forming a ring. The trolley body is a trapezoidal planar structure with upper and lower layers. The upper layer has grating plates, the lower layer is a base plate with sealing tape around the edge, and a support plate with ventilation holes is located between the upper and lower layers. A drive device rotates the active friction wheel, which in turn drives the friction plate 6, which in turn rotates the revolving frame 7, driving the rotation of the trolley and ensuring uniform cooling of the sintered ore or oxidized pellets on the trolley. The feeding device delivers the sintered ore or oxidized pellets to the trolley, while the discharge device unloads the cooled sintered ore or oxidized pellets. The air blast system supplies cooling air through the bellows, cooling the sintered ore or oxidized pellets during rotation. The sealing system consists of a central seal and an end seal. The end seals utilize multiple rows of radial wire brushes and magnets to prevent air leakage, reducing power consumption and improving the environment. These components work together to ensure efficient and stable operation of the ring cooler and effectively cool the sintered ore.

[0063] The cold machine friction plate follower sweeping device is used to clean foreign objects on the friction plate. Its working principle is: the friction wheel 1 contacts the side of the friction plate 6 on the ring cooler rotary frame 7, and uses the friction force between the two to drive the friction wheel 1 to rotate, thereby driving the half shaft 23 and the first cylindrical gear 21 to rotate, and the first cylindrical gear 21 is engaged with the second cylindrical gear 22 to complete an increase in speed and torque transmission, driving the through shaft 33 and the first bevel gear 31 to rotate, and the first bevel gear 31 and the second bevel gear 32 are engaged to complete another increase in speed, vertical redirection and torque transmission, driving the second bevel gear 32 and the roller brush 4 at the end thereof to rotate rapidly. The roller brush 4 is at a certain radial angle to the friction plate 6, so that the rotation of the roller brush 4 can sweep foreign objects on the friction plate 6 to the outside of the friction plate 6.

[0064] The annular cooler of this embodiment includes an annular cooler body and the aforementioned annular cooler friction plate follower sweeping device. This device efficiently and quickly cleans the surface of the friction plate 6, preventing particles from entering between the friction plate 6 and the active friction wheel, which could cause the active friction wheel to slip and affect the operating efficiency of the annular cooler. Furthermore, the annular cooler of this invention does not require an additional power source to clean the friction plate 6, thus saving energy and reducing production costs.
