Description

Technical Field

[0001] The invention relates to sintering equipment, in particular to a sintering surface material mixing system, and belongs to the technical field of sintering. Background Art

[0002] In the existing technology, the traditional fuel addition technique involves mixing a portion of the fuel with the sintered ore mix, return ore, and flux according to a specific ratio. The remaining portion of the fuel is then added later in the primary mixing process. The goal is to coat the surface of the mixed material particles with some of the fuel, thereby increasing the fuel's active reaction surface and increasing its combustion rate. However, with the development of sintering technology, high-vacuum exhaust sintering processes are widely used. The fuel coated on the surface of the mixed material particles will be drawn into the flue by the high-vacuum exhaust, thereby reducing the effectiveness of the secondary fuel addition sintering process.

[0003] To address these issues, some researchers have proposed a new sintering fuel splitting process: a portion of the fuel is mixed with the sintering mix and used in the pelletizing process; the remaining portion of the fuel is applied to the surface of the sintering mix particles on the upper deck of the sintering machine. While directly sprinkling the secondary fuel on the surface of the sintering mix particles can significantly prevent the fuel from being drawn into the flue, achieving uniform mixing between the secondary fuel and the mix particles on the upper deck of the sintering machine is a crucial prerequisite for improving fuel combustion efficiency and ensuring the quality of the sintered ore.

[0004] In order to achieve uniform mixing between the secondary external fuel and the upper mixed material particles of the sintering machine, the existing technology achieves uniform mixing between the secondary external fuel and the upper mixed material particles by arranging a mixing rake tooth structure on the sintering machine that can reciprocate in the length direction of the sintering machine (such as CN220418082U). However, the operation mode of this type of rake tooth structure is mainly to swing within a certain range of front and back, and it is not a circular motion. The rake tooth position is fixed and can only rake out certain grooves on the material surface of the trolley. The material within the groove range has a certain mixing effect, but it cannot achieve sufficient mixing of the surface material across the entire width. Summary of the Invention

[0005] In response to the problem of poor mixing effect of sintering surface mixture and fuel in the existing technology, the present invention provides a sintering surface material mixing system. By designing a rotating U-shaped material mixing rod without a main shaft structure as a stirring and mixing wear-resistant part for the sintering surface material, on the one hand, stirring mixing of the surface material can be achieved in the width direction of the entire sintering material surface. On the other hand, due to the limitation of no main shaft, the mixing depth is deeper than that of the existing rake tooth structure under the same outer diameter, which can significantly improve the mixing degree of the sintering surface material, significantly improve the rationality of fuel distribution, effectively promote fuel utilization efficiency and reduce fuel consumption, and greatly improve the sintering product rate and sintered ore quality.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0007] A sintering surface material mixing system, the system includes a support, a driving shaft, a driven shaft, a U-shaped material leveling rod and a driving device. A support is provided on both sides of the sintering trolley in the width direction. The driving device is provided on one of the supports. The U-shaped material leveling rod is located in the upper part of the inner cavity of the sintering trolley, and one end of the U-shaped material leveling rod is connected to the driving device on one side of the sintering trolley through the driving shaft, and the other end is connected to the support on the other side of the sintering trolley through the driven shaft. The driving device drives the U-shaped material leveling rod to rotate in the upper part of the inner cavity of the sintering trolley through the driving shaft and the driven shaft, thereby achieving mixing of the sintering surface material.

[0008] Preferably, the U-shaped material leveling rod includes a horizontal section and a bent section. The bent sections are connected to both ends of the horizontal section, and the outer ends of the two bent sections face the same direction. The outer ends of the two bent sections are respectively connected to the ends of the driving shaft and the driven shaft.

[0009] Preferably, mounting holes are formed at the outer ends of both bent sections, and perforated connectors are provided at the ends of both the driving shaft and the driven shaft. Bolts are passed through the mounting holes and then secured to the perforated connectors, thereby connecting the two bent sections to the driving shaft and the driven shaft, respectively. Preferably, the perforated connectors are flanges.

[0010] Preferably, the horizontal section is one of a straight rod, a folding rod with at least one Z-shaped section, and a curved rod with at least one S-shaped section.

[0011] Preferably, when the horizontal section is a folding rod or a curved rod, the bending or curving direction is a horizontal direction parallel to the sintering material surface, a vertical direction perpendicular to the sintering material surface, or an oblique direction between the horizontal and vertical directions.

[0012] Preferably, when the horizontal section is a folding rod having multiple Z-shaped sections or a curved rod having multiple S-shaped sections, the bending convex depths of the multiple Z-shaped sections or the bending convex depths of the S-shaped sections are the same or different along the width direction of the sintering trolley.

[0016] Preferably, the number of the U-shaped material leveling rods is 2 to 20, preferably 3 to 10.

[0017] Preferably, the system further comprises a reinforcement ring, which is arranged between the plurality of U-shaped screed rods, and the plurality of U-shaped screed rods are connected to the outer annular surface of the reinforcement ring. Preferably, the U-shaped screed rods are connected to the outer annular surface of the reinforcement ring via a pipe clamp type connector.

[0018] Preferably, the system comprises a plurality of the reinforcement rings, and the plurality of reinforcement rings are evenly distributed along the width direction of the sintering trolley.

[0019] Preferably, at least one arc-shaped chamber is formed inside the ring body of the reinforcement ring, and at least one movable body is placed in any of the arc-shaped chambers, and the movable body can move freely within the arc-shaped chamber. Preferably, the movable body is one or more of a cylinder, a sphere, or an ellipsoid.

[0020] Preferably, the bottom end of the support is connected to the ground or the sintering machine frame via a translation mechanism, and the support moves in the longitudinal direction of the sintering machine via the translation mechanism.

[0021] Preferably, the translation mechanism includes a slide rail, a pulley or slider, and a reciprocating drive motor. The slide rail is laid on the ground or on the sintering machine frame along the length of the sintering machine. The bottom end of the support is mounted on the slide rail via a pulley or slider. The reciprocating drive motor is mounted on the support and connected to the pulley or slider. The reciprocating drive motor drives the pulley or slider to cause the support to reciprocate on the slide rail.

[0022] Preferably, the support comprises a lower support and an upper support. The bottom end of the lower support is connected to the ground or to the sintering machine frame. The top end of the lower support is hingedly connected to the bottom end of the upper support. A drive device is disposed on the top of the upper support. A swing motor is also disposed on the lower support. The swing motor has a swing shaft extending upward and connected to the upper support. The swing motor drives the swing shaft to swing back and forth, thereby driving the upper support to swing back and forth along the length of the sintering machine with its bottom end as the swing center.

[0023] Preferably, the drive device includes a rotating motor and a coupling. The rotating motor is disposed at the top of the support, and the rotating shaft of the rotating motor is connected to the driving shaft via the coupling. Preferably, the driving shaft and the support, and the driven shaft and the support, are connected via independent bearings and bearing seats, respectively.

[0024] In the present invention, a pair of supports with supporting functions are arranged oppositely on both sides of the sintering trolley in the width direction (referring to the horizontal direction perpendicular to the running direction of the sintering trolley), and a driving device and a driving shaft connected to the driving device are arranged on the top of one of the supports, and a driven shaft is arranged on the top of the other support through a bearing and a bearing seat, and the axis of the driving shaft and the axis of the driven shaft coincide with each other. It should be noted that the setting height of the driving shaft and the driven shaft are both higher than the upper edge of the sintering trolley. The two ends of the U-shaped material leveling rod (which can be regarded as a U-shaped structure formed by bending the end parts of a long rod in the same direction, and the angle formed with the original rod body after bending is preferably about 60°~120°) are detachably connected to the driving shaft and the driven shaft respectively (for example, connected by bolts), and then when the driving shaft rotates, the U-shaped material leveling rod and the driven shaft will rotate accordingly. It should be noted that the U-shaped material leveling rod includes a horizontal section located in the middle and a bent section located at both ends. The bent section is connected to the driving shaft and the driven shaft in a vertical or nearly vertical form (preferably, the axis of the bent section and the axis of the driving shaft form an angle of about 60° to 120°), and the horizontal section is located as a whole in the space above and on the upper side of the inner cavity of the sintering trolley (that is, the length of the horizontal section is not greater than the width of the inner cavity of the sintering trolley, and preferably, a certain distance is left between the two ends of the horizontal section and the inner walls on both sides in the width direction of the trolley (generally preferably 10 to 60 mm, preferably 20 to 50 mm). That is, the U-shaped material leveling rod can perform circular motion in a certain vertical space (that is, in the space above and on the upper side of the inner cavity of the sintering trolley) under the rotation of the driving shaft, thereby achieving the purpose of stirring and mixing the surface material of the sintering trolley (including sintering mixture and solid fuel). In addition, the design of a U-shaped material leveling rod without a main shaft is beneficial to improving the mixing depth and significantly reducing the sticking phenomenon of the non-stirring part of the stirring facility.

[0025] In the present invention, during the rotation of the active shaft, the U-shaped material leveling rod will perform circular motion in the vertical space with the axis of the active shaft as the rotation center. During this process, the horizontal section of the U-shaped material leveling rod will first rotate downward into the surface material, and then move forward or backward in the material layer in an arc-shaped trajectory and then come out from the surface of the material layer. As the U-shaped material leveling rod continues to rotate in a circular manner, its horizontal section will frequently enter and exit the surface material to achieve mixing of the surface fuel and the sintering mixture. In a preferred embodiment, in order to improve the mixing effect on the sintered surface material, the horizontal section of the U-shaped material leveling rod is designed as a folding rod with at least one Z-shaped segment or a curved rod with at least one S-shaped segment (or at least one Z-shaped segment and at least one S-shaped segment). Then, in the process of the horizontal section entering the surface material, the Z-shaped segment and / or S-shaped segment that bends or curves outward with the axis of the active shaft as the center can enhance the stirring effect on the surface material. Compared to a straight-rod horizontal section, a horizontal bend or curvature parallel to the material surface can enhance the mixing effect of the material layer along the length of the sintering machine; a vertical bend or curvature perpendicular to the material surface can enhance the mixing effect of the material layer along the vertical direction of the sintering machine; and an inclined bend or curvature oblique to the material surface can enhance the mixing effect of the material layer along both the length and vertical directions of the sintering machine. It should be noted that when the horizontal section is a folding or curved rod, the determination of whether the bending or curvature direction is parallel to the horizontal direction of the sintering material surface, perpendicular to the vertical direction of the sintering material surface, or oblique between the horizontal and vertical directions is based on the state when the horizontal section just contacts the surface of the sintering material layer.

[0026] Furthermore, Z-shaped segments and / or S-shaped segments with different convex depths (referring to the vertical distance between the bending inflection point or the bending inflection point of the Z-shaped segment or the S-shaped segment and the axis of the driving shaft) can be simultaneously provided on the horizontal segment. When the horizontal segment breaks the material layer, serrated feeding gaps of different sizes can be formed in the width direction of the sintering machine. As the horizontal segment gradually penetrates into the material layer, the materials on both sides of the width direction of the serrated gap will collapse into the gap, which is beneficial to improve the mixing degree of the materials in the vertical direction, and thus improve the overall mixing effect of the surface materials.

[0027] In the present invention, a plurality of circumferentially distributed U-shaped sparging rods are provided between the driving shaft and the driven shaft. Each rotation of the driving shaft can stir the sintering surface material layer multiple times, thereby facilitating improved mixing efficiency of the sintering surface material. In a further preferred embodiment, in the circumferential direction of rotation of the U-shaped sparging rods, the depth of penetration into the material layer, the bending or curving method, and the bending or curving degree of the horizontal sections of the plurality of U-shaped sparging rods are all the same or different. By cyclically stirring the plurality of U-shaped sparging rods with different shapes, the mixing degree of the sintering surface material can be significantly improved.

[0028] In the present invention, a reinforcement ring is further provided between the multiple U-shaped material leveling rods. The design of the reinforcement ring can effectively improve the strength of the horizontal section of the U-shaped material leveling rod, thereby preventing the rod from being unnecessarily bent or even broken. According to the actual working conditions, multiple reinforcement rings are evenly arranged in the width direction. In a preferred embodiment, at least one arc-shaped chamber is provided inside the ring body of the reinforcement ring (in the width direction, the positions of the arc-shaped chambers provided inside the ring bodies of different reinforcement rings are the same or different), and at least one cylindrical, spherical or ellipsoidal movable body is placed in any arc-shaped chamber. When the reinforcement ring rotates with the multiple U-shaped material leveling rods, the movable body moves freely in the arc-shaped chamber and collides with the inner wall of the arc-shaped chamber, thereby causing the reinforcement ring to vibrate. The reinforcement ring then transmits the vibration to the U-shaped material leveling rod, which can effectively reduce or even avoid the sticking phenomenon on the U-shaped material leveling rod and the reinforcement ring. Preferably, the U-shaped material leveling rod is designed to have a circular or elliptical radial cross-section to further reduce the sticking phenomenon.

[0029] In the present invention, the supports located on both sides of the sintering trolley in the width direction primarily support the driving shaft, driven shaft, U-shaped sparger, and drive device, enabling the horizontal section of the U-shaped sparger to stir the surface material in the sintering trolley. In a preferred embodiment, the supports are designed to have a structure that reciprocates horizontally or swings along the length of the sintering machine by providing a translation mechanism or a swing motor (in the case of a swinging structure, the supports are divided into a lower support and an upper support, and the lower and upper supports are articulated using a pin or a universal ball valve, allowing the upper support to rotate and swing relative to the lower support). As a result, the U-shaped sparger, while rotating and stirring the surface material, simultaneously stirs the surface material reciprocally along the length of the sintering machine under the reciprocating horizontal movement or swinging action of the supports, thereby significantly improving the mixing effect of the surface material. Furthermore, the supports can be designed as a jack-like telescopic structure, allowing the mixing depth of the U-shaped sparger to be adjusted in real time for different sintering material layer thicknesses. It should be noted that the translational structure and the rocking structure of the support can be designed separately or simultaneously.

[0030] In the present invention, the maximum diameter of the U-shaped material leveling rod is 5-50 mm, preferably 10-40 mm, and more preferably 15-30 mm. The diameters of the driving shaft and the driven shaft are respectively 30-200 mm, preferably 40-150 mm, and more preferably 50-120 cm. The width of the sintering trolley is 3-6 m, preferably 4-5.5 m. The height of the sintering trolley railing is 0.6-1.1 m, preferably 0.8-1 m. The material mixing depth is 0.01-0.3 m, preferably 0.05-0.15 m.

[0031] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0032] 1: The present invention adopts a spindleless U-shaped material mixing rod design, which can achieve stirring of all surface materials in the width direction of the sintering trolley. Compared with the existing rake tooth structure, the mixing depth is deeper under the same outer diameter, which can significantly improve the mixing degree of the surface material and greatly reduce the adhesion of the material.

[0033] 2: The present invention can significantly enhance the mixing effect and efficiency of the U-shaped material mixing rod on the surface material by designing a support structure that can perform reciprocating horizontal movement or swinging along the length direction of the sintering trolley.

[0034] 3: The sintering surface material mixing system provided by the present invention has a simple overall structure, is easy to maintain and operate, has a low investment cost, does not affect the structure of the existing sintering machine itself, has low difficulty in improvement and installation in the existing sintering system, and is convenient for large-scale industrial promotion and application.

[0123] When the system of the present invention is used for production, the U-shaped material leveling rod 4 is first extended along the width direction of the sintering trolley 6 through the support 1 so that its horizontal section 401 can penetrate into the sintering surface material layer when it rotates downward, and the driving device 5 and the swing motor 103 and / or the reciprocating driving motor 903 are started. Under the action of the driving device 5, the driving shaft 2 drives the U-shaped material leveling rod 4 and the driven shaft 3 to rotate. The rotation of the U-shaped material leveling rod 4 causes the horizontal section 401 to perform a circular motion in the vertical direction, thereby continuously stirring the sintering surface material. At the same time, The swing motor 103 or the reciprocating drive motor 903 drives the support 1 to swing along the length direction of the sintering machine (the upper support 102 swings in a certain arc with the top of the lower support 101 as the center) or translate (moves on the slide rail 901 through the pulley or slider 902), so that the horizontal section 401 performs a circular motion in the vertical direction while also translating or swinging along the length direction of the sintering machine (the swinging trajectory is an upward convex arc). Through repeated stirring in multiple directions, the mixing degree of the sintering surface material can be significantly improved.
