Description

Technical Field

[0001] This invention relates to the technical field of sintering machine baffles, and particularly to a dust-resistant and anti-jamming baffle adjustment device for the bottom material hopper of a sintering machine. Background Technology

[0002] Sintering is a crucial step in the metallurgical industry, and the uniformity and stability of the bottom layer directly affect the quality and yield of sintered ore. In a sintering machine system, the bottom hopper stores and guides the bottom material down to the bottom of the trolley. Its outlet is typically equipped with an adjustable baffle to control material flow and prevent dust generated during sintering from rising upwards. However, the actual production environment is extremely harsh; the large amounts of high-temperature, high-concentration dust generated during sintering permeate the surrounding area, causing severe corrosion to the bottom hopper and its regulating devices.

[0003] In the existing technology, the baffle adjustment mechanism of the bottom hopper mostly adopts sliding fit or ordinary rotating shaft connection. Dust can easily invade the sliding gap, rotating pair and transmission meshing surface, causing dust to accumulate between the lifting rod and the guide groove, and between the transmission shaft and the bearing seat. This increases the motion resistance, causing the baffle to be difficult to lift and adjust, or even completely jammed, which seriously affects the continuity of sintering operation and production efficiency.

[0004] In addition, the traditional symmetrical design is insufficient, and the baffle is prone to tilting due to uneven load when it is raised and lowered, which further aggravates jamming. At the same time, the connection between the baffle and the hopper body is mostly rigid or simple hinge, which is difficult to adapt to small deformations or installation errors, and is prone to jamming and stuck phenomena.

[0005] Traditional baffles can only be raised and lowered to change the opening, but cannot adjust the angle and direction of material drop. This results in uneven distribution of the bottom material in the width direction of the trolley, causing local accumulation or material deviation, which in turn affects the sintering permeability and the quality of sintered ore.

[0006] Therefore, based on the above problems, it is of great significance to improve and perfect the existing bottom hopper baffle of the sintering machine. Summary of the Invention

[0007] To solve the above problems, the present invention provides a dust-proof and anti-jamming baffle adjustment device for the bottom hopper of a sintering machine, including a hopper body, a baffle disposed at the outlet of the hopper body, and a frame support. The frame support is horizontally placed and U-shaped. Both ends of the frame support are connected to both sides of the hopper body along its length. One end of the baffle is connected to the hopper body through a support and guide mechanism.

[0008] The support and guiding mechanism includes support slide rails. Two support slide rails are symmetrically arranged on one side of the hopper body facing the inner side of the frame support. Vertical guide grooves are opened on the support slide rails. Lifting rods are slidably installed in the guide grooves on both support slide rails. The bottom of the two lifting rods is hinged to the baffle.

[0009] The hopper body is also equipped with a lifting drive assembly that controls the up and down sliding of the lifting rod.

[0010] Preferably, the lifting drive assembly includes a drive shaft symmetrically and rotatably mounted on the hopper body, a telescopic rod hinged to the drive shaft, an L-shaped connecting rod mounted on the telescopic ends of both telescopic rods, a drive slider rotatably mounted on the connecting rod, and the drive slider connected to the lifting rod.

[0011] Preferably, a drive worm is rotatably mounted on the hopper body along its height direction, and driven worm wheels that mesh with the drive worm are mounted on both transmission shafts.

[0012] Preferably, a dustproof box is fitted around the drive worm and the driven worm wheel, and the dustproof box has symmetrical relief grooves for the telescopic rod to swing.

[0013] Preferably, the hopper body is provided with fan-shaped side sealing plates on both sides of the discharge port. The center of the side sealing plate is rotatably connected to the middle of the hopper body. A limiting circular plate is rotatably installed on the side sealing plate near the center via a connecting shaft. A limiting guide groove is installed on the baffle along its height direction. The cross section of the limiting guide groove is set as a T-shape that matches the connecting shaft and the limiting circular plate.

[0014] Preferably, the lifting rod is slidably disposed within the support rail via a rolling guide assembly. The rolling guide assembly includes pulleys symmetrically rotatably embedded in the lifting rod, and the support rail is provided with guide grooves adapted to the pulleys.

[0015] Preferably, the lifting rod is also equipped with dust scrapers that slope outward from the surface of the lifting rod towards the outside of the guide groove at both ends of the pulley, and the dust scrapers slide and adapt to the guide groove.

[0016] Preferably, an outer protective cover is installed under the frame support via a connecting bracket and fitted onto the outside of the hopper body. The outer protective cover is connected to the lifting rod.

[0017] In summary, this application includes at least one of the following beneficial technical effects: I. This invention transforms the sliding friction between the lifting rod and the supporting slide rail into rolling friction by setting a rolling guide assembly, thus reducing motion resistance. Simultaneously, the symmetrically installed inclined dust scrapers on the lifting rod actively clean the dust accumulated in the guide groove during up-and-down movement, ensuring a clean rolling path for the pulleys. Even when operating in a high-concentration dust environment for extended periods, the lifting rod can still rise and fall smoothly, avoiding the jamming and jamming problems caused by dust intrusion in traditional devices.

[0018] Second, when the baffle rises to a certain height, the side sealing plate will drive the baffle to rotate around the hinge point, thereby changing the opening direction between the bottom of the baffle and the discharge port. Within the same height, the drop angle and direction of the bottom material can be adjusted, so that the material position is fixed and the material is evenly distributed, avoiding local accumulation or uneven material distribution, and improving the quality and stability of the bottom material layer of the sintering machine.

[0019] Third, by setting a fan-shaped side sealing plate and having it slide in cooperation with the baffle through a T-shaped limiting guide groove, the present invention can always cover the lateral gap between the baffle and the hopper body during the baffle lifting process. During the material feeding process of the hopper body, it prevents the bottom material from leaking or splashing from the gaps between the baffle and the side of the hopper body, ensuring that the position of the material is fixed and the material is evenly distributed, and improving the environmental quality around the equipment and reducing material waste.

[0029] The following combination Figures 1-7 The embodiments of the present invention will be described in detail below.

[0030] This application discloses a dust-resistant and anti-jamming baffle adjustment device for the bottom material hopper of a sintering machine. This invention is mainly used in the process of adjusting the bottom material distribution and baffle opening of the sintering machine. In terms of technical effect, it can avoid the problems of baffle lifting jamming, jamming, and accelerated wear caused by dust intrusion. In particular, the lifting rod rolls up and down in the support slide rail through the rolling guide component, and the dust scraper actively cleans the dust accumulated in the guide groove, transforming sliding friction into rolling friction and achieving self-cleaning, ensuring smooth adjustment without jamming in a high dust environment.

[0031] Reference Figure 1 , Figure 2 and Figure 4 As shown, a dust-proof and anti-jamming baffle adjustment device for the bottom material hopper of a sintering machine includes a hopper body 1, a baffle 2 disposed at the outlet of the hopper body 1, and a frame support 3. The hopper body 1 is used to store and guide the bottom material to fall, and the baffle 2 can adjust the opening to control the material flow rate. At the same time, the baffle 2 itself can also effectively prevent the dust generated during the sintering process from flying upward.

[0032] The frame support 3 is placed horizontally and is U-shaped. Both ends of the frame support 3 are connected to the two sides of the hopper body 1 along its length. One end of the baffle 2 is connected to the hopper body 1 through the support and guide mechanism 4.

[0033] The support and guide mechanism 4 includes support slide rails 40. Two support slide rails 40 are symmetrically arranged on one side of the hopper body 1 facing the inner side of the frame support 3. The symmetrical arrangement can ensure that the baffle 2 is evenly stressed and will not jam or tilt due to uneven load during adjustment. Vertical guide grooves are provided on the support slide rails 40. Lifting rods 41 are slidably installed in the guide grooves on both support slide rails 40. The bottom of the two lifting rods 41 is hinged to the baffle 2. The inner wall of the guide groove is smoothed to reduce the sliding resistance of the lifting rods 41.

[0034] The lifting rod 41 can only slide vertically up and down in the guide groove. The guide groove plays a guiding and limiting role for the lifting rod 41 throughout its entire movement. The bottom of the two lifting rods 41 is hinged to the baffle 2. The hinged connection allows the baffle 2 to automatically adapt to the material accumulation angle at the outlet when it moves with the lifting rod 41, and it will not get stuck due to minor deformation or installation errors.

[0035] The hopper body 1 is also equipped with a lifting drive assembly 5 that controls the lifting rod 41 to slide up and down.

[0036] Reference Figure 2 and Figure 3The diagram shows the structure of the lifting drive assembly 5. Specifically, the lifting drive assembly 5 includes two drive shafts 51 symmetrically rotatably mounted on the hopper body 1. The two drive shafts 51 are perpendicular to one side of the hopper body 1 and their axes are horizontally arranged. The drive shafts 51 are rotatably connected to the hopper body 1 through bearing seats. The bearing seats are provided with dustproof sealing rings to effectively prevent dust from entering the rotation gap and to avoid the drive shafts 51 from getting stuck or rotating poorly due to dust accumulation. Telescopic rods 52 are hinged on the drive shafts 51. L-shaped connecting rods 53 are installed at the telescopic ends of the two telescopic rods 52. A drive slider 54 is rotatably mounted on the connecting rod 53. The drive slider 54 is connected to the lifting rod 41. When the baffle 2 needs to be raised, the drive shaft 51 rotates in the forward direction, driving the telescopic rod 52 to rotate upward synchronously. During the upward rotation of the telescopic rod 52, the drive slider 54 moves upward through the connecting rod 53. At this time, the connecting rod 53 and the drive slider 54 rotate relative to each other to adapt to the angle change. At the same time, the telescopic rod 52 gradually retracts to match the movement trajectory. The drive slider 54 then carries the lifting rod 41 to rise smoothly along the guide groove, thereby driving the baffle 2 at the bottom of the lifting rod 41 to rise synchronously.

[0037] Conversely, when the baffle 2 needs to be lowered, the drive shaft 51 rotates in the opposite direction, and the drive shaft 51 drives the telescopic rod 52 to rotate downward. During the downward rotation, the telescopic rod 52 drives the drive slider 54 to move downward through the connecting rod 53. At this time, the connecting rod 53 and the drive slider 54 rotate relative to each other again. The telescopic rod 52 gradually extends to adapt to the motion trajectory. The drive slider 54 drives the lifting rod 41 to gradually descend, and then drives the baffle 2 on the lifting rod 41 to descend synchronously, thereby realizing the precise lifting and lowering control of the baffle 2.

[0038] Reference Figure 2 and Figure 3 The diagram shows the transmission structure of the driven worm gear and the driving worm 60. Specifically, the hopper body 1 is also equipped with a driving worm 60 that rotates along its height direction, and driven worm gears 61 that mesh with the driving worm 60 are installed on both transmission shafts 51. The driven worm gears 61 are fixed to one end of the transmission shaft 51 by a key connection. The teeth of the driven worm gears 61 and the driving worm 60 are matched and maintain precise meshing. The driven worm gears 61 drive the transmission shaft 51 to rotate together. After the transmission shaft 51 rotates, it drives the telescopic rod 52, which is hinged to it, to swing up or down. The telescopic rod 52 gradually extends and retracts during the swinging process, and drives the lifting rod 41 to rise and fall vertically along the guide groove through the L-shaped connecting rod 53 and the driving slider 54, thereby precisely controlling the opening of the baffle 2.

[0039] The meshing of the driving worm 60 and the driven worm wheel 61 in the entire transmission chain also has a self-locking characteristic, so that even if there is external vibration or material impact, the baffle 2 will not slide down on its own and can reliably maintain the adjusted position.

[0040] Reference Figure 1 The diagram shows the structure of the dustproof box 70. Specifically, the dustproof box 70 is fitted over the drive worm 60 and the driven worm wheel 61, and the dustproof box 70 has symmetrically provided clearance grooves 71 for the telescopic rod 52 to swing. By completely enclosing the drive worm 60 and the driven worm wheel 61 inside, the large amount of high-concentration dust generated during the sintering process can be effectively isolated, preventing dust from entering between the meshing tooth surfaces of the drive worm 60 and the driven worm wheel 61, thus avoiding poor meshing, increased wear, or even jamming caused by dust accumulation.

[0041] Reference Figure 2 , Figure 4 and Figure 5 The diagram shows the structure of the rolling guide assembly 9. Specifically, the lifting rod 41 is slidably mounted in the support rail 40 via the rolling guide assembly 9. The rolling guide assembly 9 includes pulleys 91 symmetrically rotatably embedded in the lifting rod 41. The support rail 40 has a receiving groove 92 adapted to the pulleys 91. When the lifting rod 41 moves up and down in the guide groove, the symmetrically arranged pulleys 91 roll synchronously in the receiving groove 92. The pulleys 91 on both sides jointly bear the weight of the lifting rod 41 and the baffle 2, ensuring that the lifting rod 41 always maintains a vertical posture and does not tilt. At the same time, the symmetrical structure also avoids uneven wear of the pulleys 91 or uneven wear of the receiving groove 92 caused by unilateral force, thus extending the service life.

[0042] Since the rolling guide component 9 transforms sliding friction into rolling friction, it reduces the load requirements of the lifting drive component 5 and makes the baffle 2 adjustment more sensitive and precise. Even when operating in a high dust environment for a long time, the rolling cooperation between the pulley 91 and the receiving groove 92 is still smooth and without jamming, which improves the dust resistance and operational reliability of the entire baffle adjustment device.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The diagram illustrates a structure that ensures the surface of the receiving groove 92 remains clean at all times. Specifically, a dust scraper 10, inclined from the surface of the lifting rod 41 towards the outside of the guide groove, is installed on both ends of the pulley 91 on the lifting rod 41. The dust scraper 10 is slidably adapted to the receiving groove 92. The dust scraper 10 is made of wear-resistant elastic material, and its inclined direction causes the tip of the dust scraper 10 to extend from the inside of the lifting rod 41 towards the outside of the receiving groove 92. When the lifting rod 41 moves up and down, there is always a dust scraper 10 on both sides of the pulley 91 actively cleaning the receiving groove 92, pushing the accumulated dust in the receiving groove 92 outward, and ensuring that the surface of the receiving groove 92 along the rolling path of the pulley 91 remains clean at all times.

[0044] This reduces the possibility of dust entering the rolling contact surface between the pulley 91 and the receiving groove 92, ensuring that the pulley 91 can roll smoothly and that the lifting rod 41 can move easily and without jamming. This guarantees the sensitivity and reliability of the baffle 2 adjustment and extends the maintenance cycle and service life of the entire rolling guide assembly 9.

[0045] Reference Figure 6 and Figure 7 The diagram shows the cooperative structure of the side sealing plate 80 and the limiting guide groove 82. Specifically, the hopper body 1 has fan-shaped side sealing plates 80 on both sides of the discharge port. The center of the side sealing plate 80 is rotatably connected to the middle of the hopper body 1, and its curvature matches the swing range of the baffle 2. The side sealing plate 80 can effectively block the lateral gaps generated between the baffle 2 and the hopper body 1 during the adjustment process, preventing the base material from leaking or splashing from the gaps, and also preventing dust from rising from the gaps. A limiting circular plate 81 is rotatably installed on the side sealing plate 80 near the center via a connecting shaft. The baffle 2 is equipped with a limiting guide groove 82 arranged along its height direction. The cross-section of the limiting guide groove 82 is T-shaped to match the connecting shaft and the limiting circular plate 81. The interior of the limiting guide groove 82 is a wide groove to accommodate the limiting circular plate 81, and the groove opening is a narrow slit to accommodate the connecting shaft. The limiting circular plate 81 slides up and down in the limiting guide groove 82 but cannot be dislodged, while the connecting shaft moves in the narrow slit, thereby reliably connecting the side sealing plate 80 and the baffle 2 together.

[0046] When the baffle 2 rises under the action of the lifting rod 41, the limiting circular plate 81 will slide relative to the limiting guide groove 82 along the vertical direction of the groove. Due to the T-shaped cross-section design of the limiting guide groove 82, the limiting circular plate 81 will always maintain its cooperation with the limiting guide groove 82 during the sliding process and will not disengage. At the same time, this sliding cooperation will not cause any obstruction or jamming to the rise of the baffle 2. The baffle 2 can rise and fall freely without interference from the side sealing plate 80.

[0047] When the baffle 2 rises to a certain height, the limiting circular plate 81 has slid to the bottom of the limiting guide groove 82 or a specific position. When it continues to rise, the limiting circular plate 81 will drive the side sealing plate 80 to rotate around the pivot at its center. After the side sealing plate 80 rotates, it pulls the baffle 2 along the hinge between the baffle 2 and the lifting rod 41 through the connecting shaft and the limiting circular plate 81, thereby changing the opening direction between the bottom of the baffle 2 and the discharge port. Thus, the drop angle and direction of the bottom material can be adjusted within the same height, thereby ensuring that the position of the material is fixed and the material is evenly distributed, and there will be no local accumulation or uneven material distribution, which improves the quality and stability of the bottom material of the sintering machine.

[0048] Reference Figure 1As shown, this is a schematic diagram of the structure of the outer protective cover 11. Specifically, an outer protective cover 11 is installed on the outside of the hopper body 1 via a connecting bracket below the frame support 3. The connecting bracket is a telescopic structure composed of inner and outer tubes that are interlocked, which can extend and retract with the lifting rod. The outer protective cover 11 is connected to the lifting rod 41, and the outer protective cover 11 can rise and fall synchronously with the lifting rod 41. The lower end of the outer protective cover 11 extends further to the vicinity of the baffle 2, covering the gaps on both sides of the discharge port, as well as the side sealing plate 80, the limiting guide groove 82, and other structures. This forms multiple layers of isolation with the previously set dustproof box 70, dustproof sealing ring, dust scraper 10, and the outer protective cover 11 around the adjustment mechanism, progressively blocking dust intrusion.

[0049] During operation: First, when it is necessary to adjust the opening of the baffle 2, the external power drives the worm gear 60 to rotate. The worm gear 60 drives the driven worm wheel 61 to rotate, and the driven worm wheel 61 drives the transmission shaft 51 to rotate together. The forward or reverse rotation of the transmission shaft 51 causes the telescopic rod 52 to swing up or down. The telescopic rod 52 gradually extends and retracts during the swinging process, and drives the drive slider 54 to move through the L-shaped connecting rod 53. The drive slider 54 is connected to the lifting rod 41, converting the rotational motion into the linear motion of the lifting rod 41 in the vertical direction.

[0050] Step 2: When the lifting rod 41 moves up and down, the dust scrapers 10 on both sides of the pulley 91 move synchronously, actively pushing the accumulated dust in the receiving groove 92 outward, keeping the rolling path clean, thereby ensuring that the lifting rod 41 always moves up and down smoothly and without jamming.

[0051] Step 3: When the lifting rod 41 rises or falls, the baffle 2 rises or falls synchronously, thereby adjusting the opening of the discharge port to control the flow rate of the bottom material. The hinged connection allows the baffle 2 to automatically adapt to the material accumulation angle at the outlet when it moves with the lifting rod 41.

[0052] Step 4: During the lifting and lowering of the baffle 2, the fan-shaped side sealing plates 80 set on both sides of the hopper body 1 work in sync. When the baffle 2 initially rises, the limiting circular plate 81 slides relative to the limiting guide groove 82, and the side sealing plate 80 remains stationary, effectively blocking the lateral gap between the baffle 2 and the hopper body 1, preventing the leakage of the base material and the rising of dust.

[0053] Step 5: When the baffle 2 rises to a certain height, the limiting circular plate 81 slides relative to the bottom or a specific position of the limiting guide groove 82. At this time, as the baffle 2 continues to rise, the limiting circular plate 81 will drive the side sealing plate 80 to rotate around the pivot at its center. The rotation of the side sealing plate 80 pulls the baffle 2 through the connecting shaft and the limiting circular plate 81, causing the baffle 2 to rotate along its hinge point with the lifting rod 41. This changes the opening direction between the bottom of the baffle 2 and the discharge port, allowing the drop angle and direction of the base material to be adjusted within the same height, ensuring a fixed material placement position and uniform material distribution, and avoiding local accumulation or uneven material distribution.
