Description

Technical Field

[0001] The utility model relates to the technical field of sintering machines, in particular to a flat material feeder for a sintering machine. Background Art

[0002] Sintering is the process of mixing iron-containing raw materials, flux, fuel, return ore and other mineral powders in a certain ratio and adding appropriate amount of water. After mixing and granulating, they are spread on the sintering machine's trolley. After the sintering material is ignited on the surface, under the forced ventilation of the lower bellows, the fuel in the material layer burns from top to bottom and releases heat. The mixture undergoes a series of physical and chemical changes under the action of high temperature and produces a certain liquid phase. As the temperature of the material layer decreases and cools, the liquid phase consolidates the mineral powder particles into blocks.

[0003] Since most of the sintering return ore is mainly generated by sintered ore on the material surface, in order to ensure the production and quality of sintered ore during the sintering process, the material surface of the sintering machine should be kept flat. However, in the actual production process, due to the wear and tear between the rollers of the multi-roller distributor in the sintering machine distribution platform, some materials on the sintering machine distribution platform will fall through the roller gap onto the sintering trolley under the sintering machine distribution platform, resulting in an uneven material surface on the sintering trolley, an increase in the return rate and a decrease in the yield rate.

[0026] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 4 As shown, one embodiment of the utility model provides a flat material device for a sintering machine, comprising at least one flat material plate 11, which is arranged below the material distribution platform of the sintering machine and above the trolley of the sintering machine, and a material passing gap is formed between the bottom of the flat material plate 11 and the trolley of the sintering machine;

[0028] The material gap is used to block the materials on the sintering machine trolley that are higher than the material gap, so as to smooth the materials on the sintering trolley under the sintering machine distribution platform.

[0029] It should be explained that in the sintering machine, the sintering machine distribution platform is arranged above the sintering machine trolley, and the sintering machine distribution platform is arranged at an angle, the silo discharge port is located above the sintering machine distribution platform, and the sintering machine distribution platform includes a distributor, and the distributor includes a plurality of distribution rollers. The material is discharged from the silo discharge port and falls onto the plurality of distribution rollers, and the plurality of distribution rollers rotate to evenly spread the material, and the spread material rolls from the distributor to the sintering machine trolley.

[0030] However, after long-term use, the multiple feeding rollers of the feeder will wear out, resulting in gaps between two adjacent feeding rollers. In this way, part of the material falling on the feeder will fall from the gaps between the feeding rollers onto the sintering machine platform below. As the sintering machine platform runs, part of the material falling from the gaps between the feeding rollers will be covered by the material rolling down from the feeder. The part of the material falling from the gaps between the feeding rollers is itself uneven, resulting in an uneven surface of the entire material after covering. The uneven surface will increase the return rate and reduce the yield rate.

[0031] In this embodiment, the flat plate 11 is arranged between the sintering machine feeding platform and the sintering machine trolley, and a material passing gap is formed between the bottom of the flat plate 11 and the sintering machine trolley. In this way, the material on the sintering machine trolley below the sintering machine feeding platform will be blocked by the flat plate 11 when moving, so that the material with a height exceeding the flat plate 11 cannot pass through the filtering gap, and the height of the material after being smoothed by the flat plate 11 is basically the same, that is, the material surface of the material after being smoothed by the flat plate 11 is flat, so that when the material spread on the sintering machine feeding platform is spread on the material after being smoothed by the flat plate 11, the material surface of the entire material can be basically kept flat, thereby weakening the sintering edge effect, reducing the sintering return rate, and improving the sintering finished product rate.

[0032] As a preferred embodiment, Figure 1 and Figure 2 As shown, the flat material feeder for sintering machine includes a cross bar 8, two fixed sleeves 10 and a connecting mechanism, wherein the flat material plate 11 is detachably mounted on the cross bar 8, the length direction of the flat material plate 11 is the same as the length direction of the cross bar 8, and the position of the flat material plate 11 near the top is connected to the cross bar 8. The two fixed sleeves 10 are respectively mounted on both ends of the cross bar 8, and the flat material plate 11 is located between the two fixed sleeves 10, and the length direction of the cross bar 8 is consistent with the width direction of the sintering machine trolley, so that the length direction of the flat material plate 11 is consistent with the width direction of the sintering machine trolley, that is, the projection of the flat material plate 11 on the sintering machine trolley is parallel and perpendicular to the long side of the sintering machine trolley. Furthermore, a connecting mechanism is installed on each fixed sleeve 10, and the top end of the connecting mechanism is hoisted on the sintering machine feeding platform.

[0033] Preferably, the connecting mechanism includes a pull rod 3 and a first nut 4, wherein the bottom end of the pull rod 3 is fixed on the fixed sleeve 10, and the pull rod 3 is vertically arranged, and two round holes are opened on the steel plate of the sintering machine feeding platform, and the top ends of the two pull rods 3 pass through the two round holes on the steel plate of the sintering machine feeding platform. The pull rod 3 is provided with an external thread, and the first nut 4 is threadedly installed on the top end of the pull rod 3.

[0034] During installation, the flat plate 11 is first installed on the crossbar 8, and then the two fixing sleeves 10 are inserted into the two ends of the crossbar 8, and then the two tie rods 3 on the fixing sleeve 10 are passed through the two round holes on the steel plate of the sintering machine distribution platform, and finally the first nut 4 is installed on the top of the tie rod 3. In this way, the flat plate 11 can be hoisted under the sintering machine distribution platform.

[0035] It should be noted that in this embodiment, the height of the cross bar 8 and the flat material plate 11 can be adjusted, that is, the distance between the flat material plate 11 and the sintering machine trolley can be adjusted. Specifically, when adjusting the height of the flat material plate 11, it is only necessary to tighten the first nut 4 on the pull rod 3. Since the distance between the flat material plate 11 and the sintering machine trolley can be adjusted, it can adapt to different sintering machine material layer thicknesses and is more practical.

[0036] As a preferred embodiment, Figure 1 and Figure 2As shown, the fixing sleeve 10 is limited on the cross bar 8 by a limiting member, and the limiting member is used to limit the movement of the fixing sleeve 10 along the axis direction of the cross bar 8 to maintain the stability of the fixing sleeve 10. Specifically, the limiting member includes two limiting rings 9, and the two limiting rings 9 are welded on the cross bar 8, and the fixing sleeve 10 is limited between the two limiting rings 9. Specifically, when installing the fixing sleeve 10, the first limiting ring 9 in the limiting member can be inserted into the cross bar 8, and then the limiting ring 9 and the cross bar 8 are welded, and then the fixing sleeve 10 is inserted into the cross bar 8 and fits on the first limiting ring 9, and then the second limiting ring 9 is inserted into the cross bar 8, and the second limiting ring 9 is fit with the fixing sleeve 10, and finally the second limiting ring 9 and the cross bar 8 are welded.

[0037] Optionally, in order to facilitate the removal of the fixing sleeve 10, the limiting ring 9 is set to be detachable. Specifically, a plurality of springs 12 are evenly arranged around the axis of the limiting ring 9, one end of each spring 12 is fixed to the inner wall of the limiting ring 9, and the other end thereof points to the axis of the limiting ring 9, and an arc block 14 is fixedly connected to the end of the spring 12 pointing to the axis of the limiting ring 9, and a plurality of through holes are evenly opened around the axis of the limiting ring 9, and the through holes correspond to the springs 12 one by one, and a rod body 13 is fixedly connected to each arc block 14, and the rod body 13 passes through the through hole on the arc block 14.

[0038] In this way, when installing the limit ring 9, the rod body 13 can be pulled outward, and the rod body 13 drives the arc block 14 to move outward. At this time, the spring 12 is in a compressed state, and then the cross bar 8 passes through multiple arc blocks 14. After the limit ring 9 moves to a suitable position, the rod body 13 is released. Under the action of the spring 12, multiple arc blocks 14 move simultaneously toward the axial direction of the cross bar 8 and thus tightly rest against the side of the cross bar 8.

[0039] As a preferred embodiment, the sintering machine flattener also includes a rocker 7 and a limit mechanism. The rocker 7 is welded to one end of the cross bar 8, and the rocker 7 is perpendicular to the cross bar 8. The rocker 7 is used to drive the cross bar 8 to rotate around the axis of the cross bar 8. When the rocker 7 drives the cross bar 8 to rotate, the flattening plate 11 can be driven to rotate a certain angle, so that the inclination angle between the flattening plate 11 and the sintering machine platform changes, that is, the angle between the flattening plate 11 and the sintering machine material surface can be adjusted. The purpose is to further adjust the flattening effect.

[0040] After the rocker 7 rotates, the rocker 7 is limited by the limiting mechanism to prevent the rocker 7 from returning to its original position.

[0041] Specifically, Figure 1 and Figure 3As shown, the limiting mechanism includes a limiting rod 1 and a limiting plate 2, wherein the limiting plate 2 is provided with a plurality of insertion holes in sequence along its length direction, and the limiting plate 2 is vertically installed below the feeding platform of the sintering machine and close to the rocker 7. Specifically, the top end of the limiting plate 2 is welded to the iron frame of the feeding platform stairs, and the lower surface of the limiting plate 2 is lower than the rocker 7. Furthermore, the limiting rod 1 is an arc-shaped rod.

[0042] It should be noted that Figure 3 The direction from left to right is the incoming material direction, and the material will give the flat plate 11 a rightward thrust. In order to prevent the flat plate 11 from rotating counterclockwise, the limit rod 1 can be inserted into the socket of a suitable height of the limit plate 2, so that the end of the limit rod 1 is against the rocker 7 to prevent the rocker 7 from rotating counterclockwise, thereby ensuring that the cross bar 8 and the flat plate 11 will not rotate counterclockwise.

[0043] Moreover, after the tilt angle of the flat material plate 11 is adjusted by rotating the rocker 7 to drive the cross bar 8, the limit rod 1 can be inserted into the appropriate hole on the limit plate 2, and the end of the limit rod 1 close to the rocker 7 is against the rocker 7, thereby limiting the rocker 7, and the rocker 7 cannot be reset, ultimately keeping the flat material plate 11 at the set tilt angle.

[0044] Preferably, Figure 1 and Figure 2 As shown, the flat plate 11 is detachably connected to the cross bar 8. Specifically, a plurality of screws 5 are provided on the cross bar 8 along its length direction, the screws 5 are perpendicular to the cross bar 8, and a plurality of round holes corresponding to the screws 5 are provided on the flat plate 11 along its length direction, and the round holes are located in the upper half of the flat plate 11.

[0045] When installing the flat plate 11, it is only necessary to align the circular hole on the flat plate 11 with the corresponding screw rod 5, and then pass the screw rod 5 through the circular hole on the flat plate 11, and finally install the second nut 6 on the screw rod 5 and tighten the second nut 6. This makes it convenient to install and disassemble the flat plate 11, and to clean the flat plate 11 later.

[0046] It should be noted that the flat material plate 11 can be arranged in multiple pieces or in one piece according to its size. When the flat material plate 11 is arranged in one piece, it is necessary to ensure that the length of the flat material plate 11 is not less than the width of the sintering machine trolley, that is, it is necessary to ensure that the flat material plate 11 can smooth the entire material surface. When the flat material plate 11 is arranged in multiple pieces, it is necessary to ensure that the total length of the multiple flat material plates 11 is not less than the width of the sintering machine trolley. Figure 1 As shown, in this embodiment, the flat material plates 11 are provided in three pieces, and the three flat material plates 11 are arranged in sequence along the length direction of the cross bar 8 .

[0047] Preferably, the flat plate 11 is a hard template.

[0048] Optionally, the flattening plate 11 is a belt, and the use of the belt has little effect on the air permeability of the sintering machine. When the belt is used, the belt and the sintering machine material surface are flattened through surface contact.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the insides of two components.
