Abstract

This utility model discloses a sintering surface material mixing system, including a support, a drive shaft, a driven shaft, a U-shaped uniform material rod, and a drive device. By designing a rotary, shaftless U-shaped uniform material rod as a wear-resistant component for mixing and uniformly agitating the sintering surface material, it can achieve agitation of all surface material along the width of the sintering trolley. Compared to existing rake-tooth structures, it achieves a deeper mixing depth for the same outer diameter, thus significantly improving the mixing degree of the surface material and greatly reducing material adhesion. Furthermore, by designing a support structure that reciprocates or swings horizontally along the length of the sintering trolley, the mixing effect and efficiency of the U-shaped uniform material rod on the surface material can be significantly enhanced simultaneously. The sintering surface material mixing system of this utility model has a simple overall structure, is easy to maintain and operate, has low investment costs, does not affect the existing sintering machine's structure, and is easy to improve and install within existing sintering systems, facilitating large-scale industrial promotion and application.

Description

Technical Field

[0001] This utility model relates to sintering equipment, specifically to a sintering surface material mixing system, and belongs to the field of sintering technology. Background Technology

[0002] In existing technologies, traditional fuel addition techniques involve mixing a portion of the fuel with sintered homogenized ore, recycled ore, and flux in a specific ratio, while adding the remaining fuel later in the initial mixing process. The aim is to coat the surface of the mixed particles with fuel, thereby increasing the reactive surface area and improving combustion speed. However, with the development of sintering processes and the widespread application of high-negative-pressure exhaust sintering, the fuel coated on the surface of the mixed particles is often drawn into the flue by the high-negative-pressure exhaust, thus reducing the effectiveness of secondary fuel addition in sintering.

[0003] To address the aforementioned issues, some researchers have proposed a novel sintering fuel addition process: a portion of the fuel is mixed with the sintering mix and participates in the granulation of the sintering mix; the other portion of externally added fuel is added to the surface of the sintering mix particles on the upper layer of the sintering machine trolley. Although directly sprinkling the secondary externally added fuel onto the surface of the sintering mix particles can significantly prevent fuel from being drawn into the flue, achieving uniform mixing between the secondary externally added fuel and the upper layer of the sintering mix particles is a crucial prerequisite for improving fuel combustion efficiency and ensuring the quality of the sintered ore.

[0004] To achieve uniform mixing between the secondary external fuel and the upper layer of the sintering machine, existing technologies use a mixing rake structure that can reciprocate along the length of the sintering machine to achieve uniform mixing between the secondary external fuel and the upper layer of the sintering machine (e.g., CN220418082U). However, the operation of this type of rake structure is mainly oscillating within a certain range, not circular motion. The rake teeth are in a fixed position and can only rake out certain grooves on the material surface of the trolley. The material within the groove has a certain mixing effect, but it cannot achieve full mixing of the surface material across the entire width. Utility Model Content

[0005] To address the problem of poor mixing effect between sintering surface mixture and fuel in existing technologies, this invention provides a sintering surface material mixing system. By designing a U-shaped, shaftless, rotary mixing rod as a wear-resistant agitator for the sintering surface material, this system achieves agitation and mixing of the surface material across the entire width of the sintering surface. Furthermore, due to the absence of a shaft, the mixing depth is greater than that of existing rake-tooth structures with the same outer diameter, significantly improving the mixing uniformity of the sintering surface material, noticeably improving fuel distribution, effectively promoting fuel utilization efficiency and reducing fuel consumption, and greatly improving the sintering yield and sinter quality.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

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

[0008] Preferably, the U-shaped material leveling rod includes a horizontal section and a bent section. 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 connected to the ends of the driving shaft and the driven shaft, respectively.

[0009] Preferably, mounting holes are provided at the outer ends of both bent sections, and perforated connectors are provided at the ends of both the drive shaft and the driven shaft. Bolts are passed through the mounting holes and connected to the perforated connectors for fixation, thereby connecting the two bent sections to the drive shaft and the driven shaft respectively. Preferably, the perforated connector is a flange.

[0010] Preferably, the horizontal segment is one of a straight bar, a bent bar with at least one Z-shaped segment, or a curved bar with at least one S-shaped segment.

[0011] Preferably, when the horizontal section is a bent or curved rod, the direction of its bending or curvature is either 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 bent bar with multiple Z-shaped sections or a curved bar with multiple S-shaped sections, the bending outward convex depth of the multiple Z-shaped sections or the bending outward convex depth of the S-shaped sections are the same or different along the width direction of the sintering trolley.

[0013] Preferably, the surface of the U-shaped material distribution bar is also covered with a wear-resistant layer. Preferably, the wear-resistant layer is a wear-resistant coating or a wear-resistant carbon steel layer.

[0014] Preferably, the radial cross-section of the U-shaped uniform material rod is one of a circle, an ellipse, or a polygon.

[0015] Preferably, the system includes multiple U-shaped material leveling rods, both ends of which are connected to the drive shaft and the driven shaft respectively, and the multiple U-shaped material leveling rods are evenly distributed along the circumference of the drive shaft.

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

[0017] Preferably, the system further includes a reinforcing ring disposed between multiple U-shaped material distribution rods, and all U-shaped material distribution rods are connected to the outer ring surface of the reinforcing ring. Preferably, the U-shaped material distribution rods are connected to the outer ring surface of the reinforcing ring via pipe clamp connectors.

[0018] Preferably, the system includes a plurality of reinforcing rings, which are evenly distributed along the width direction of the sintering trolley.

[0019] Preferably, at least one arc-shaped cavity is formed inside the reinforcing ring, and at least one movable body is placed in any one of the arc-shaped cavities, the movable body being able to move freely within the arc-shaped cavity. 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 to the sintering machine frame via a translation mechanism. The support moves along the length of the sintering machine via the translation mechanism.

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

[0022] Preferably, the support includes 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 hinged to the bottom end of the upper support. A drive device is located on the top of the upper support. A swing motor is also provided on the lower support, with its swing shaft extending upwards and connected to the upper support. The swing motor drives the swing shaft to reciprocate, thereby causing the upper support to reciprocate along the length of the sintering machine with its bottom end as the swing center.

[0023] Preferably, the drive device includes a rotary motor and a coupling. The rotary motor is mounted on the top of the support, and the shaft of the rotary motor is connected to the drive shaft via the coupling. Preferably, the drive shaft is connected to the support, and the driven shaft is connected to the support, respectively, via independent bearings and bearing housings.

[0024] In this invention, a pair of supporting supports are arranged opposite each other 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). A drive device and a drive shaft connected to the drive device are arranged on the top of one support, while a driven shaft is arranged on the top of the other support through a bearing and a bearing seat. The axes of the drive shaft and the driven shaft coincide. It should be noted that the height of both the drive shaft and the driven shaft is higher than the upper edge of the sintering trolley. The two ends of the U-shaped uniform material rod (which can be regarded as a U-shaped structure formed by bending the two ends of a long rod in the same direction, and the angle between the bent part and the original rod is preferably about 60°~120°) are detachably connected to the drive shaft and the driven shaft respectively (for example, by bolts). Thus, when the drive shaft rotates, both the U-shaped uniform material rod and the driven shaft will rotate accordingly. It should be noted that the U-shaped uniform feed rod includes a horizontal section in the middle and bent sections at both ends. The bent sections are connected to the drive shaft and driven shaft in a perpendicular or nearly perpendicular manner (preferably, the axis of the bent section forms an angle of approximately 60° to 120° with the axis of the drive shaft). The horizontal section is located entirely within the upper part and upper side of the sintering trolley cavity (i.e., the length of the horizontal section is not greater than the width of the sintering trolley cavity; preferably, a certain distance is left between the two ends of the horizontal section and the inner walls on both sides of the trolley in the width direction (generally 10 to 60 mm, preferably 20 to 50 mm). Thus, under the rotation of the drive shaft, the U-shaped uniform feed rod can perform circular motion within a certain vertical space (i.e., within the upper part and upper side of the sintering trolley cavity), thereby achieving the purpose of stirring and mixing the surface material (including sintering mixture and solid fuel) of the sintering trolley. Furthermore, designing a U-shaped uniform feed rod without a main shaft not only improves the mixing depth but also significantly reduces the material sticking phenomenon in the non-stirring parts of the mixing equipment.

[0025] In this invention, during the rotation of the drive shaft, the U-shaped uniform feed rod rotates in a circular motion in vertical space around the axis of the drive shaft. During this process, the horizontal section of the U-shaped uniform feed rod first rotates downwards into the surface material, then travels forward or backward along an arc-shaped trajectory within the material layer before exiting from the surface. As the U-shaped uniform feed rod continuously rotates in a circular motion, its horizontal section frequently enters and exits the surface material to achieve uniform mixing of the surface fuel and the sintered mixture. In a preferred embodiment, to improve the mixing effect on the sintered surface material, the horizontal section of the U-shaped uniform feed rod is designed as a folded rod with at least one Z-shaped segment or a curved rod with at least one S-shaped segment (or simultaneously having at least one Z-shaped segment and at least one S-shaped segment). Then, during the process of the horizontal section entering the surface material, the Z-shaped segment and / or S-shaped segment, which bends or curves outwards around the axis of the drive shaft, can enhance the agitation effect on the surface material. Compared to a straight horizontal section, a horizontal bend or curve parallel to the material surface can increase the mixing effect of the material layer along the length of the sintering machine, while a vertical bend or curve perpendicular to the material surface can increase the mixing effect of the material layer in the vertical direction. An inclined bend or curve inclined to the material surface can simultaneously increase the mixing effect of the material layer along both the length and vertical directions. It should be noted that when the horizontal section is a bent or curved rod, the determination of whether the bend or curve is parallel to the sintering material surface, perpendicular to the sintering material surface, or inclined (between horizontal and vertical) is based on the state when the horizontal section just touches the surface of the sintering material layer.

[0026] Furthermore, on the horizontal section, Z-shaped sections and / or S-shaped sections with different convex depths (referring to the vertical distance from the bending inflection point of the Z-shaped section or S-shaped section to the axis of the drive shaft) can be set simultaneously. When the material layer is broken into the horizontal section, serrated feeding gaps of different sizes can be formed in the width direction of the sintering machine. As the horizontal section gradually penetrates into the material layer, the material on both sides of the serrated gap in the width direction will collapse into the gap, which will help improve the mixing degree of the material in the vertical direction, thereby improving the overall mixing effect of the surface material.

[0027] In this invention, multiple circumferentially distributed U-shaped material-mixing rods are arranged between the drive shaft and the driven shaft. Each rotation of the drive shaft agitates the sintering surface material layer multiple times, thereby improving the mixing efficiency of the sintering surface material. In a more preferred embodiment, in the circumferential direction of the rotation of the U-shaped material-mixing rods, the depth of the horizontal sections of the multiple U-shaped material-mixing rods penetrating the material layer, the bending or bending method, and the degree of bending or bending are all the same or different. Through the cyclic agitation of multiple U-shaped material-mixing rods with different shapes, the degree of mixing of the sintering surface material can be significantly improved.

[0028] In this invention, reinforcing rings are provided between multiple U-shaped material leveling rods. The design of these reinforcing rings effectively improves the strength of the horizontal section of the U-shaped material leveling rods, preventing unnecessary large-scale bending or even breakage. Multiple reinforcing rings are evenly arranged in the width direction according to actual working conditions. In a preferred embodiment, at least one arc-shaped cavity is formed inside the reinforcing ring (the positions of the arc-shaped cavities inside different reinforcing rings may be the same or different in the width direction). At least one movable body, such as a cylinder, sphere, or ellipsoid, is placed in any one of the arc-shaped cavities. As the reinforcing ring rotates with the multiple U-shaped material leveling rods, the movable body moves freely within the arc-shaped cavity and collides with the inner wall of the arc-shaped cavity, causing the reinforcing ring to vibrate. The reinforcing ring then transmits this vibration to the U-shaped material leveling rods, effectively reducing or even preventing material adhesion on the U-shaped material leveling rods and reinforcing rings. Preferably, designing the U-shaped material leveling rods with a radial cross-section of a circle or ellipse further reduces material adhesion.

[0029] In this invention, the supports located on both sides of the sintering trolley in the width direction mainly support the drive shaft, driven shaft, U-shaped uniform material rod, and drive device, enabling the horizontal section of the U-shaped uniform material rod to stir the surface material in the sintering trolley. In a preferred embodiment, the supports are designed to reciprocate horizontally or swing along the length of the sintering machine by setting a translation mechanism or a swing motor (when it is a swing structure, the support is divided into a lower support and an upper support, which are hinged by a pin or universal ball valve, so that the upper support can rotate relative to the lower support). This allows the U-shaped uniform material rod to simultaneously reciprocate along the length of the sintering machine while rotating and stirring the surface material, under the action of the reciprocating horizontal movement or swing of the supports, thus significantly improving the mixing effect of the surface material. Furthermore, the supports can also be designed as a jack-type telescopic structure, allowing real-time adjustment of the mixing depth of the U-shaped uniform material rod for different sintering material layer thicknesses. It should be noted that the translational and swaying structures of the supports can be designed separately or simultaneously.

[0030] In this invention, the maximum diameter of the U-shaped uniform material 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 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 sideboards 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 this utility model are as follows:

[0032] 1. This utility model adopts a U-shaped uniform material rod design without a main shaft, which can realize the 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 surface materials and greatly reduce the adhesion of materials.

[0033] 2: This utility model, by designing a support structure that reciprocates or swings horizontally along the length of the sintering trolley, can simultaneously and significantly enhance the mixing effect and efficiency of the U-shaped uniform material rod on the surface material.

[0034] 3. The sintering surface material mixing system provided by this utility model has a simple overall structure, is easy to maintain and operate, has 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 easy to promote and apply on a large scale in industrial applications.

[0122] Example 28 is repeated, except that the drive shaft 2 and the support 1, and the driven shaft 3 and the support 1 are connected by independent bearings and bearing housings respectively.

[0123] When using the system described in this utility model for production, firstly, the U-shaped uniform material rod 4 is extended along the width direction of the sintering trolley 6 via the support 1, so that its horizontal section 401 can penetrate into the sintering surface material layer when rotating downwards. Then, the drive device 5, the swing motor 103, and / or the reciprocating drive motor 903 are started. Under the action of the drive device 5, the drive shaft 2 drives the U-shaped uniform material rod 4 and the driven shaft 3 to rotate. The rotation of the U-shaped uniform material rod 4 causes the horizontal section 401 to perform circular motion in the vertical direction, thereby continuously agitating the sintering surface material. Simultaneously... The oscillating motor 103 or the reciprocating drive motor 903 drives the support 1 to oscillate (the upper support 102 swings at a certain arc with the top of the lower support 101 as the center) or translate (moves on the slide rail 901 through pulleys or sliders 902), so that the horizontal section 401 performs circular motion in the vertical direction and translates or oscillates along the length of the sintering machine (the oscillation trajectory is an upward convex arc). Through repeated stirring in multiple directions, the uniformity of the sintering surface material can be significantly improved.
