Description

Technical Field

[0001] This invention relates to the field of dry quenched coke transportation technology, and specifically to a reverse brushing mechanism for cleaning dry quenched coke conveyor belts. Background Technology

[0002] Xianggang Coking Plant currently has three dry quenching coke ovens, among which the coke conveyor belt is the most important conveying device for transporting coke to the blast furnace for ironmaking. The service life of the belt is directly related to production costs, and the service life of the belt is also related to the cleanliness of its surface.

[0003] The existing coke conveyor belts are equipped with scraper machines for cleaning the belt. The scraper removes surface materials by rotating the belt itself. The scraper is fixed in position and cannot be adjusted according to the belt's usage after long-term use. This significantly reduces the belt's lifespan. After prolonged use, the scraper wears out and needs to be replaced entirely, greatly increasing the operating cost of the cleaning device. Furthermore, the belt runs above the idler rollers, which are arc-shaped. The scraper's cleaning effect on the belt is poor, resulting in coke powder residue remaining on the belt and sticking to it. Over time, this leads to an increasing dust content in the entire conveyor belt corridor, causing environmental hazards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a reverse brushing mechanism for cleaning conveyor belts used in dry quenching coke production.

[0005] The reverse brushing mechanism for cleaning a dry quenching coke conveyor belt of the present invention includes: A cleaning roller is installed near the belt roller, the cleaning roller includes a cylinder body, and the surface of the cylinder body is equipped with bristles; Installation mechanism, the installation mechanism being used to carry the cleaning roller and install it at the end of the belt; A drive mechanism is provided to drive the cleaning roller to rotate, and the rotation direction of the cleaning roller is the same as that of the belt roller. A distance adjustment mechanism is provided for changing the distance between the cleaning roller and the belt.

[0006] In some embodiments, the mounting mechanism includes a mounting plate and a mounting shaft, wherein the mounting plate is fixedly connected to the mounting structure of the belt roller; The two ends of the cleaning roller are connected to the mounting plate via mounting shafts.

[0007] In some embodiments, the mounting plate is provided with an adjustment hole, a slider is installed in the adjustment hole, and the mounting shaft is mounted on the rotation axis of the cylinder, with its end rotatably connected to the slider. The drive mechanism is connected to the mounting shaft via a transmission. The distance adjustment mechanism is used to change the position of the slider in the adjustment hole.

[0008] In some embodiments, the driving mechanism includes a driving wheel, which is sleeved on the surface of the mounting shaft, and the surface of the driving wheel is provided with a pitch-changing portion; The drive mechanism also includes a rotating gear and a gear ring. The end of the drive wheel has a mounting cavity. The gear ring is fixedly mounted on the inner wall of the mounting cavity. The rotating gear is connected to the gear ring via a reversing gear. A gear shaft is rotatably connected to the center of the reversing gear. The gear shaft is fixedly connected to the mounting plate.

[0009] In some embodiments, an axial slip ring is mounted at the center of the drive wheel via a bearing, and the axial slip ring is slidably connected to the mounting shaft along the axial direction. The variable pitch part consists of contact rings of different diameters fixedly sleeved on the surface of the drive wheel. Multiple contact rings are arranged in a stepped manner from the outside to the inside, arranged according to their diameter.

[0010] In some embodiments, a control component is also included, which controls the pitch variable to change the minimum distance between the drive wheel and the belt roller.

[0011] In some embodiments, the control component may be an adjusting rod that is mounted parallel to the shaft. One end of the adjusting rod is fixedly connected to an axial slip ring, and the other end of the adjusting rod movably passes through the mounting plate. The adjusting rod is provided with a locking element.

[0012] In some embodiments, the mounting shaft has mounting slots at both ends, and a sliding hole communicating with the mounting slot is provided on the mounting shaft. The adjusting rod is inserted into the mounting slot and fixedly connected to the inner wall of the axial slip ring through a connector that passes through the sliding hole.

[0013] In some embodiments, the mounting plate is slidably connected to the mounting structure of the belt roller; The distance adjustment mechanism is used to drive the mounting plate to carry the cleaning roller and change the distance between it and the belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The drive mechanism of this invention drives the mounting shaft to rotate the cleaning roller and the belt roller in the same direction, so that the bristles on the cleaning roller run in the opposite direction to the belt part that it contacts, thus effectively removing the coke and coke powder adhering to the belt surface. The distance adjustment mechanism can change the distance between the cleaning roller and the belt. After the bristles on the cleaning roller wear down and become shorter, the distance adjustment mechanism can make the shorter bristles continue to make sufficient contact with the belt, thereby reducing the number of cleaning roller replacements and increasing the service life of the cleaning roller.

[0015] 2. This invention uses flexible bristles to contact the arc-shaped belt located on the belt roller during rotation, effectively cleaning the belt and preventing coke and coke powder carried by the belt from falling into the belt conveyor and increasing the dust content of the conveyor, thus effectively reducing the possibility of environmental accidents caused by excessive dust content in the belt conveyor.

[0016] 3. In this invention, the drive wheel in the drive mechanism contacts the belt roller. When the belt starts running, the cleaning roller can rotate in the same direction as the belt roller using the force of the existing belt roller rotation. That is, the bristles on the cleaning roller can effectively remove the coke and coke powder attached to the belt surface. At the same time, the rotation of the cleaning roller does not require external power, effectively utilizing the force of the existing belt roller rotation to achieve energy-saving operation.

They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0021] Example 1: Please see Figures 1-2 The reverse brushing mechanism for cleaning a dry quenching coke conveyor belt of the present invention includes: Cleaning roller 1 is installed near belt roller 5. Cleaning roller 1 includes a cylinder body 101 and brush bristles 102 are installed on the surface of the cylinder body 101. Mounting mechanism 2 is used to carry the cleaning roller 1 and install it at the end of the belt; Drive mechanism 3 is used to drive the cleaning roller 1 to rotate, and the rotation direction of the cleaning roller 1 is the same as the rotation direction of the belt roller 5. Distance adjustment mechanism 4 is used to change the distance between the cleaning roller 1 and the belt.

[0022] The mounting mechanism 2 includes a mounting plate 21 and a mounting shaft 22. The mounting plate 21 is fixedly connected to the mounting structure of the belt roller 5. The mounting structure of the belt roller 5 can be a frame supporting the belt roller 5 or a hopper located at the end of the belt. The two ends of the cleaning roller 1 are connected to the mounting plate 21 via the mounting shaft 22.

[0023] An adjustment hole 23 is provided on the mounting plate 21, and a slider 24 is installed in the adjustment hole 23. The mounting shaft 22 is installed on the rotation axis of the cylinder 101, and its end is rotatably connected to the slider 24. The drive mechanism 3 is connected to the mounting shaft 22 via a transmission. The drive mechanism 3 is preferably a motor that can move synchronously with the slider 24. The output shaft of the motor is connected to the mounting shaft 22 via a gear. The distance adjustment mechanism 4 is used to change the position of the slider 24 in the adjustment hole 23. Specifically, the distance adjustment mechanism 4 is a screw connected to the slider 24. The screw is rotatably connected to the slider 24 and is threaded onto the mounting plate 21 with the sliding axis of the slider 24 being coincident. The movement of the slider 24 is achieved by rotating the screw on the mounting plate 21.

[0024] Working principle: First, the cleaning roller 1 is installed at the end of the belt through the mounting mechanism 2. Then, the distance between the cleaning roller 1 and the belt is changed through the distance adjustment mechanism 4 so that the bristles 102 on the cleaning roller 1 contact the belt on the belt roller 5. Then, while the belt is running, the drive mechanism 3 is started so that the motor in the drive mechanism 3 drives the mounting shaft 22 to carry the cleaning roller 1 and the belt roller 5 to rotate in the same direction. This makes the bristles 102 and the belt part they contact run in opposite directions, that is, the bristles 102 on the cleaning roller 1 effectively remove the coke and coke powder adhering to the surface of the belt. Compared to the scraper structure in the prior art, the distance adjustment mechanism 4 can change the distance between the cleaning roller 1 and the belt. After the bristles 102 on the cleaning roller 1 wear down and become shorter, the distance adjustment mechanism 4 can make the shortened bristles 102 continue to make sufficient contact with the belt, thereby reducing the number of times the cleaning roller 1 needs to be replaced and increasing the service life of the cleaning roller 1. When the flexible bristles 102 rotate, they can effectively contact the arc-shaped belt located on the belt roller 5, effectively cleaning the belt and preventing the coke and coke powder carried by the belt from falling off and increasing the dust content of the belt corridor. This effectively reduces the possibility of environmental accidents caused by excessive dust content in the belt corridor.

[0025] Example 2: Please see Figures 3-5 As a further improvement to Embodiment 1, unlike Embodiment 1, the drive mechanism 3 includes a drive wheel 31, which is sleeved on the surface of the mounting shaft 22, and the surface of the drive wheel 31 is provided with a pitch-changing part 32, which can change the minimum distance between the drive wheel 31 and the belt roller 5. The drive mechanism 3 also includes a rotating gear 33 and a gear ring 34. The end of the drive wheel 31 is provided with a mounting cavity. The gear ring 34 is fixedly installed on the inner wall of the mounting cavity. The rotating gear 33 is connected to the gear ring 34 through a reversing gear 35. A gear shaft 36 is rotatably connected to the center of the reversing gear 35. The gear shaft 36 is fixedly connected to the mounting plate 21.

[0026] Working principle: In the initial state, the drive wheel 31 is in contact with the belt roller 5. When the belt starts running, the belt roller 5 will rotate. The rotation of the belt roller 5 will cause the drive wheel 31 to rotate in the opposite direction, carrying the toothed ring 34. When the drive wheel 31 rotates, the rotating gear 33 will rotate through the transmission of the reversing gear 35. Because the reversing gear 35 reverses the rotation of the drive wheel 31, the rotating gear 33 can carry the mounting shaft 22 and the cleaning roller 1 to rotate in the same direction as the belt roller 5. This enables the bristles 102 on the cleaning roller 1 to run in the opposite direction to the belt part it contacts. That is, the bristles 102 on the cleaning roller 1 can effectively remove the coke and coke powder adhering to the belt surface. At the same time, the rotation of the cleaning roller 1 does not require external power, effectively utilizing the force of the existing belt roller 5 rotation to achieve energy-saving operation.

[0027] Example 3: Please see Figures 3-5 As a further improvement to Embodiment 2, unlike Embodiment 2, an axial slip ring 37 is installed in the center of the drive wheel 31 via a bearing. The axial slip ring 37 is slidably connected to the mounting shaft 22 along the axial direction. The axial slip ring 37 can only slide along the central axis of the mounting shaft 22. When the axial slip ring 37 rotates, it can effectively transmit force to the mounting shaft 22, and simultaneously realize the rotation of the mounting shaft 22 carrying the cleaning roller 1. The pitch-changing part 32 consists of contact rings of different diameters fixedly sleeved on the surface of the drive wheel 31. Multiple contact rings are arranged in a stepped manner from the outside to the inside according to their diameter. By sliding the drive wheel 31 along the mounting shaft 22, the contact rings in contact with the belt roller 5 are changed, thereby changing the minimum distance between the drive wheel 31 and the belt roller 5.

[0028] It also includes a control component 6, which controls the pitch control unit 32 to change the minimum distance between the drive wheel 31 and the belt roller 5.

[0029] The control component 6 can be an adjusting rod 61 that is parallel to the shaft 22. One end of the adjusting rod 61 is fixedly connected to the axial slip ring 37, and the other end of the adjusting rod 61 movably passes through the mounting plate 21. The adjusting rod 61 is provided with a locking element 62, which can be a thread and nut or a fixing pin and pin hole.

[0030] The control unit 6 can be an automated mechanism that can drive the axial slip ring 37 to move and lock, such as a self-locking electric cylinder or pneumatic cylinder.

[0031] The mounting shaft 22 has mounting slots 25 at both ends, and a sliding hole 26 communicating with the mounting slots 25 is provided on the mounting shaft 22. The adjusting rod 61 is inserted into the mounting slot 25, and the adjusting rod 61 is fixedly connected to the inner wall of the axial slip ring 37 through the connector 63 that passes through the sliding hole 26.

[0032] The mounting plate 21 is slidably connected to the mounting structure of the belt roller 5; the distance adjustment mechanism 4 is used to drive the mounting plate 21 to carry the cleaning roller 1 to change the distance between it and the belt.

[0033] Working principle: In the initial state, the contact ring with the largest diameter in the pitch-changing section 32 of the device is in contact with the surface of the belt roller 5, and at this time the bristles 102 of the cleaning roller 1 can effectively contact the belt. When the bristles 102 shorten after prolonged use, the adjusting rod 61 of the control component 6 carries the axial slip ring 37 outward, which moves the contact ring with the largest initial diameter to the outside of the belt roller. Then, the distance adjustment mechanism 4 changes the distance between the cleaning roller 1 and the belt, so that the contact ring with the smaller diameter can be released from the belt roller 5, and the shortened bristles 102 can also contact the belt again, thereby extending the service life of the cleaning roller 5 and reducing the replacement frequency. In Embodiment 2, the part where the belt roller 5 contacts the drive mechanism 3 is a part that exists in the prior art. In the prior art, in order to ensure the effective and stable operation of the belt, the length of the belt roller 5 must be greater than the width of the belt. Therefore, this device also has the advantage of being easy to install on existing equipment. In Embodiments 2 and 3, it is assumed that since the bristles 102 are made of flexible material, the resistance when they come into contact with the belt is less than the force transmitted from the belt roller 5 to the drive wheel 31, thus ensuring that the drive wheel 31 rotates and drives the cleaning roller 1 to rotate. Of course, if the contact force between the bristles 102 and the belt, and the transmission force between the belt roller 5 and the drive wheel 31 are not easy to calculate and determine, the variable pitch part 32 on the drive wheel 31 can be directly set as a gear, and then the corresponding gear teeth can be added to the belt roller 5 to enable meshing transmission and ensure transmission force.

[0034] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
