Description

Technical Field

[0001] This utility model relates to the field of slag cooler technology, specifically a buffer device for a drum slag cooler. Background Technology

[0002] Slag coolers are mainly used to cool boiler slag. They are classified into drum slag coolers, vibratory slag coolers, water-cooled slag coolers, and disc slag coolers. Utility model patent CN220418112U discloses a buffer device for a drum slag cooler, including a base with positioning plates at both ends of the base top. One positioning plate has a first positioning seat, and the other has a second positioning seat. A slag cooling mechanism is rotatably connected between the first and second positioning seats. Buffer mechanisms, including positioning components and shock-absorbing components, are installed on the top of the base at both ends of the slag cooling mechanism. A power component is installed on the base outside the slag cooling mechanism. A slag inlet pipe is embedded inside the first positioning seat, and a slag outlet pipe is embedded inside the second positioning seat. This device prevents excessive shaking of the drum from causing compression and collision of components, which could damage the device, reduce its service life, and increase maintenance costs.

[0003] However, the aforementioned existing technology has the following problems: the meshing between the pinion and the gear is easily affected by vibration, resulting in tooth loss, jamming, and other phenomena. Once this happens, the rotation of the slag cooling sleeve becomes unstable, making it impossible to achieve efficient slag cooling operations, thus leading to low structural stability and low efficiency of the drum slag cooling machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by developing a buffer device for a drum slag cooler, which solves the problem of low structural stability in existing drum slag coolers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A buffer device for a drum slag cooler includes a slag cooling sleeve and a support base. The slag cooling sleeve is rotatably mounted inside the support base. A detachable driven gear ring is mounted on the slag cooling sleeve, and the driven gear ring is driven by an adaptive drive assembly. The adaptive drive assembly includes a base plate, a geared motor, a connecting arm, a drive gear, and a belt drive mechanism. The geared motor is mounted on the base plate. One end of the connecting arm is rotatably connected to the output shaft of the geared motor, and the other end of the connecting arm is rotatably connected to the drive gear. The drive gear meshes with the driven gear ring. The connecting arm is equipped with a belt drive mechanism, one end of which is driven by the output shaft of the geared motor, and the other end is driven by the drive gear. A buffer assembly is mounted at the bottom of the support base.

[0007] Furthermore, the adaptive drive assembly is equipped with a detachable shock absorber, one end of which is rotatably connected to the connecting arm and the other end of which is rotatably connected to the base plate.

[0008] Furthermore, the buffer assembly includes a connecting seat, a rotating pin, a leaf spring, a locking bolt, and a base. The connecting seat is connected to the leaf spring via the rotating pin, and a detachable base is installed below the leaf spring. The leaf spring and the base are connected via the locking bolt.

[0009] Furthermore, the belt drive mechanism includes a driving pulley, a driven pulley, and a drive belt. One end of the drive belt is connected to the driving pulley, and the other end is connected to the driven pulley. The driving pulley is fixedly mounted on the output shaft of the geared motor, and the driven pulley is fixedly mounted on the rotating shaft of the drive gear.

[0010] Furthermore, the support base includes a frame and support wheels. The support wheels are evenly distributed on the frame and are rolled to connect with the curved surface of the cold slag sleeve.

[0011] Furthermore, the frame is equipped with fixed reinforcing ribs, and there are multiple reinforcing ribs that are evenly distributed.

[0012] Furthermore, feet are fixedly connected to both sides of the bottom of the frame, and the bottom of the feet is detachably connected to the buffer assembly.

[0013] Furthermore, the shock absorber includes a cylinder body, a piston rod, and a piston. The piston is sleeved on one end of the piston rod, and the piston rod and piston are integrated and housed inside the cylinder body. The cylinder body is movably connected to the piston rod and piston. A spring is clamped between the piston and the contact surface at the bottom of the cylinder body. Oil inlet and outlet ports are provided on the cylinder body.

[0014] Furthermore, an oil reservoir is installed on the base plate, and an oil nozzle is provided on one side of the lower end of the oil reservoir, which is connected to the oil inlet and outlet ports on the cylinder body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model relates to a buffer device for a drum slag cooler, which improves the structural stability of the drum slag cooler by modifying structural components and connections. Firstly, the adaptive drive component ensures that the driven gear ring remains stably engaged with the slag cooler sleeve during vibration, driving the sleeve to rotate. This maintains constant engagement between the drive gear and the driven gear ring, preventing tooth slippage and jamming, thus ensuring stable operation of the slag cooler. This solves the problem in existing technologies where vibration easily affects the meshing of the pinion and gears, leading to tooth slippage and jamming, resulting in low structural stability of the drum slag cooler.

[0017] Secondly, a shock absorber structure is set on the adaptive drive component to alleviate and eliminate the vibration generated by the adaptive drive component during the driving of the cold slag jacket, as well as the vibration generated by the cold slag jacket during operation, making the operation of the cold slag jacket more stable.

[0018] Finally, a buffer assembly is installed at the bottom of the support base. The leaf springs within the buffer assembly effectively absorb the vibrational potential energy applied to the support base by the cold slag sleeve, preventing excessive swaying of the cold slag sleeve and resulting in squeezing and collision of components. This further stabilizes the operation of the cold slag machine, achieving efficient cold slag processing and improving work efficiency. Attached Figure Description

They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0027] For easier understanding, please refer to Figure 1-5 This application discloses a buffer device for a drum slag cooler, comprising a slag cooler sleeve 1 and a support base 6. The slag cooler sleeve 1 is rotatably mounted inside the support base 6. Several support bases 6 are provided, specifically two, one on each side of the slag cooler sleeve 1, supporting the entire slag cooler sleeve 1. A detachable driven gear ring 4 is mounted on the slag cooler sleeve 1, and the slag cooler sleeve 1 and the driven gear ring 4 are connected and fixed by bolts. The driven gear ring 4 is driven by an adaptive drive component 5, which ensures that the driven gear ring 4 is stably engaged and drives the slag cooler sleeve 1 to rotate during vibration displacement. A slag inlet is provided on one side of the slag cooler sleeve 1 and a slag inlet pipe 2 is fixedly connected to it by welding. A slag outlet is provided at the lower end of the other side and a slag outlet pipe 3 is fixedly connected to it by welding.

[0028] The adaptive drive assembly 5 includes a base plate 51, a geared motor 52, a connecting arm 53, a drive gear 54, and a belt drive mechanism 55. The geared motor 52 is mounted on the base plate 51. One end of the connecting arm 53 is rotatably connected to the output shaft of the geared motor 52, and the other end is rotatably connected to the drive gear 54. The drive gear 54 meshes with the driven gear ring 4. The connecting arm 53 is equipped with a belt drive mechanism 55. One end of the belt drive mechanism 55 is connected to the output shaft of the geared motor 52, and the other end is connected to the drive gear 54, thus synchronously connecting the output shaft of the geared motor 52 and the drive gear 54 through the belt drive mechanism 55. When the adaptive drive assembly 5 is working, the geared motor 52 is started, and the rotation of the output shaft of the geared motor 52 drives the belt drive mechanism 55 to run synchronously, thereby driving the drive gear 54 to rotate synchronously. The rotating drive gear 54 drives the meshing driven gear ring 4 to rotate, realizing the rolling of the cold slag sleeve 1.

[0029] The adaptive drive assembly 5 is equipped with a detachably connected shock absorber 56. Specifically, one end of the shock absorber 56 is rotatably connected to the connecting arm 53 via a pin, and the other end of the shock absorber 56 is rotatably connected to the base plate 51 via a pin. The end of the shock absorber 56 connected to the base plate 51 has two connecting ears 57, including a first connecting ear and a second connecting ear. The first connecting ear is fixedly connected to the shock absorber 56, and the second connecting ear is fixedly connected to the base plate 51. The first connecting ear and the second connecting ear are rotatably connected via a pin. By setting the shock absorber 56 structure on the adaptive drive assembly 5, the vibration generated by the adaptive drive assembly 5 during the driving of the cold slag sleeve 1, as well as the vibration generated by the cold slag sleeve 1 during operation, is mitigated and eliminated, making the operation of the cold slag sleeve 1 more stable. This achieves efficient cold slag operation and improves work efficiency.

[0030] The adaptive drive assembly 5 can stably engage the driven gear ring 4 to drive the cold slag sleeve 1 to rotate when the cold slag sleeve 1 vibrates and displaces, and always maintain the engagement of the drive gear 54 with the driven gear ring 4. The axis of the output shaft of the geared motor 52 is parallel to the axis of the cold slag sleeve 1. When the cold slag sleeve 1 is displaced in the radial direction, the connecting arm 53 rotates around the axis of the geared motor 52, so that the drive gear 54 is always engaged with the driven gear ring 4, stably driving the cold slag sleeve 1 to rotate. This achieves adaptive adjustment of the meshing tightness between the drive gear 54 and the driven gear ring 4, avoiding misalignment, displacement, and other phenomena.

[0031] A buffer assembly 7 is installed at the bottom of the support base 6. The buffer assembly 7 includes a connecting seat 71, a rotating pin 72, a leaf spring 73, locking bolts 74, and a base 75. The connecting seat 71 and the leaf spring 73 are connected by the rotating pin 72. Specifically, the leaf spring 73 is shaped like an arc-shaped plate, with lugs at both ends. Each lug is connected to the connecting seat 71 at both ends. The rotating pin 72 passes through the lugs of the connecting seat 71 and the leaf spring 73, respectively, to tightly connect the connecting seat 71 and the leaf spring 73. A detachable base 75 is installed below the leaf spring 73, and the leaf spring 73 and the base 75 are tightly connected by locking bolts 74. Specifically, multiple locking bolts 74 are inserted into the leaf spring 73. The locking bolts 74 extend downward through the thickness of the leaf spring 73 and are threaded to the base 75. Up to four locking bolts 74 can be provided to securely and stably fix the leaf spring 73 to the base 75 from four azimuth angles. The buffering effect of the leaf spring 73 enables the buffer assembly 7 to stably and effectively absorb the vibration potential energy applied to the support base 6 by the cold slag sleeve 1, thus preventing the cold slag sleeve 1 from shaking too much and causing the components to be squeezed and collided.

[0032] The belt drive mechanism 55 includes a driving pulley, a driven pulley, and a drive belt. One end of the drive belt is connected to the driving pulley, and the other end is connected to the driven pulley, so that the drive belt connects the driving pulley and the driven pulley together to achieve transmission. The driving pulley in the belt drive mechanism 55 is fixedly mounted on the output shaft of the geared motor 52, driving the driven pulley in the belt drive mechanism 55 to be fixedly mounted on the rotating shaft of the drive gear 54. Through the use of the belt drive mechanism 55, the power of the geared motor 52 can be stably transmitted to the drive gear 54, thereby stably driving the driven gear ring 4 to drive the cold slag sleeve 1 to rotate stably.

[0033] The support base 6 includes a frame 61 and support wheels 62. Multiple support wheels 62 are evenly distributed and equidistantly mounted on the frame 61 around the axis of the cold slag sleeve 1. The support wheels 62 roll over the curved surface of the cold slag sleeve 1, and the multiple support wheels 62 stably support the cold slag sleeve 1, ensuring the stability of its rotation. The frame 61 is equipped with fixed reinforcing ribs 63, multiple of which are evenly distributed below the cold slag sleeve 1. Specifically, multiple reinforcing ribs 63 are welded to the frame 61 below the cold slag sleeve 1. The reinforcing ribs 63 effectively improve the structural strength of the frame 61, thereby ensuring the stability of the support base 6's support for the cold slag sleeve 1. Symmetrically welded feet 64 are located on both sides of the bottom of the frame 61. The bottom of the feet 64 is detachably and tightly connected to the connecting seat 71 of the buffer assembly 7 via bolts. Each frame 61 has two symmetrically arranged buffer assemblies 7 at its bottom, which stably support and buffer the vibration of the support base 6, effectively absorbing the vibration potential energy transmitted by the support base 6.

[0034] The shock absorber 56 includes a cylinder body 561, a piston rod 562, and a piston 563. The piston 563 is sleeved on one end of the piston rod 562 to form an integral unit. The piston rod 562 and piston 563 are integrally disposed inside the cylinder body 561, and the cylinder body 561 is movably connected to the piston rod 562 and piston 563. Specifically, one end of the cylinder body 561 has a slot for slidingly connecting the piston rod 562. One end of the piston rod 562 is located inside the cylinder body 561 and has the piston 563 installed thereon; the other end is connected to the connecting arm 53 via a pin. A spring 564 is sandwiched between the contact surface between the piston 563 and the inner bottom of the cylinder body 561. The spring 564 is connected to the inner bottom surface of the cylinder body 561. Specifically, a welded retaining ring is provided on the inner bottom surface of the cylinder body 561, and the spring 564 is sleeved on the retaining ring for connection. The cylinder body 561 has inlet and outlet oil ports leading into the interior of the cylinder body 561. An oil reservoir 58 is also installed on the base plate 51. An oil nozzle 59 is provided on one side of the lower end of the oil reservoir 58, leading into the interior of the reservoir 58. The oil nozzle 59 is connected to the inlet and outlet oil ports on the cylinder body 561 via an oil pipe. When the piston rod 562 moves to the bottom surface of the cylinder body 561 under the action of the vibrating cooling sleeve 1, the spring 564 provides timely reset support for the piston 563. Furthermore, the oil in the cylinder body 561 on both sides of the piston 563 can be compressed and subjected to flow resistance during the process of entering and exiting the oil reservoir 58, thereby achieving the purpose of buffering and absorbing energy. Dynamic sealing rings 565 are installed at the connection between the piston 563 and the cylinder body 561, as well as at the connection between the cylinder body 561 and the piston rod 562. The dynamic sealing rings 565 effectively ensure the sealing of the moving parts in the shock absorber 56, preventing oil leakage.

[0035] The working principle of this utility model is as follows: when the power is turned on, the reduction motor 52 is started. The reduction motor 52 drives the drive gear 54 to rotate through the belt transmission mechanism 55. Since the drive gear 54 meshes with the driven gear ring 4, the cold slag sleeve 1 starts to rotate. During the rotation of the cold slag sleeve 1, the adaptive drive component 5 plays a role. When the cold slag sleeve 1 is displaced in the radial direction, the connecting arm 53 rotates around the axis of the reduction motor 52. When the piston rod 562 moves under the drive of the vibrating cold slag sleeve 1, the spring 564 provides timely reset support for the piston 563. Moreover, the oil in the cylinder 561 on both sides of the piston 563 can be compressed and subjected to flow resistance during the process of entering and exiting the oil storage cylinder 58, thereby achieving the purpose of buffering and absorbing energy, so that the drive gear 54 always maintains meshing with the driven gear ring 4, and stably drives the cold slag sleeve 1 to rotate. Simultaneously, the buffer assembly 7 begins to operate. The vibration generated during the rotation of the slag sleeve 1 is transmitted to the connecting seat 71 through the support seat 6. The connected leaf spring 73 deforms under the connection of the rotating pin 72, absorbing the vibration potential energy and preventing excessive swaying of the slag sleeve 1, thus preventing the components from being squeezed and collided. This further makes the operation of the slag cooler more stable, thereby achieving efficient slag cooling operations and improving work efficiency.

[0036] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any changes and modifications made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the scope of protection of the present invention.
