Description

Technical Field

[0001] The utility model belongs to the technical field of sintering machines, in particular to a strength-enhancing material pressing device of a sintering machine. Background Art

[0002] As the core equipment in the sintering process, the sintering machine will produce edge effects during operation due to the airflow flowing along the walls of the space containing the solid bulk material, which will have a certain impact on the solid bulk material (forming edge gaps on both sides). This edge effect affects sintering production, quality, and operating energy consumption. Usually, after the ore is distributed to the trolley by the round roller feeder and the multi-roller distributor, it will be compacted or flattened by the pressing device and the scraping device. The pressing device is mainly used to compact the edge material to avoid the edge effect. Although the pressing device can compact the edge material, reduce its permeability and slow down the edge effect, the ore in the middle of the trolley will have its permeability reduced due to compaction, and thus cannot be burned through; existing measures to suppress the edge effect also include increasing the edge ignition temperature, making the wall wavy, and setting blind grate bars near the wall, but these measures cannot effectively prevent the sintered ore from gathering towards the middle of the trolley during the combustion process and forming side seams on both sides, and cannot effectively avoid the edge effect. Therefore, a strength-enhancing pressing device for the sintering machine is needed to improve the above problems. Utility Model Content

[0003] Aiming at the problem that the current sintering machine compacts the side materials, resulting in poor air permeability of the mineral materials in the middle of the trolley and incomplete combustion, the utility model provides a strength-enhancing material pressing device for the sintering machine, which compacts the materials on the upper part and edge of the trolley at the same time to avoid the edge effect.

[0004] The utility model is realized through the following technical solutions:

[0005] A strength-enhancing and pressing device for a sintering machine is applied to a sintering machine body. A trolley is arranged inside the sintering machine body. A mounting plate is connected to the top of the sintering machine body via a hydraulic cylinder. A pressing plate is fixed to the bottom of the mounting plate via a plurality of connecting rods. Two motors are fixed in the middle of the bottom of the mounting plate.

[0006] The output end of the motor is connected to a screw rod, and the other end of the screw rod is connected to a bearing and is arranged at the bottom of the mounting plate;

[0007] The end of the screw rod away from the motor is provided with a thread I and a thread II in opposite directions, and the thread I and the thread II are respectively connected to the nut I and the nut II, and the bottom of the nut I and the nut II are respectively hinged to the hinge rod I and the hinge rod II, and the ends of the hinge rod I and the hinge rod II are hinged and connected to the top of the side extrusion plate.

[0008] The working principle of this utility model is as follows:

[0009] After the material on the trolley is completely burned, the hydraulic cylinder is started to push the mounting plate downward, thereby driving the pressure plate to compact the material on the trolley. At this time, the material on the side of the pressure plate overflows, and the motor is started to rotate the screw counterclockwise or clockwise. Since the threads Ⅰ and Ⅱ set on the screw are in opposite directions, when the screw rotates clockwise, the nuts Ⅰ and Ⅱ approach each other, and the horizontal position of the screw does not change. Therefore, the horizontal positions of the nuts Ⅰ and Ⅱ do not change, thereby reducing the angle between the hinge rod Ⅰ and the hinge rod Ⅱ, that is, the hinge rod Ⅰ and the hinge rod Ⅱ are in opposite directions. The hinged ends of the chain rods II move in the direction away from the mounting plate, that is, pressing the side extrusion plate to flatten the side material to fill the side seam; after the edge sealing is completed, the rotation direction of the motor is changed to drive the screw rod to rotate counterclockwise. At this time, the nuts I and II move away from each other, and the angle between the hinge rods I and II becomes larger, that is, the hinged ends of the hinge rods I and II move in the direction close to the mounting plate, driving the side extrusion plate to move in the direction close to the mounting plate, and at the same time, the hydraulic cylinder is started to lift the mounting plate for the next material compaction.

[0010] As a further improvement of the present invention, "T"-shaped grooves are provided at both ends of the pressing plate, and "T"-shaped sliding blocks are provided on the side surfaces of the side extrusion plates to match the "T"-shaped grooves and be movably connected.

[0011] The side extrusion plates are movably connected to the "T"-shaped slide grooves at both ends of the pressing plate through "T"-shaped sliders, so that the side extrusion plates only move in the vertical direction without horizontal deviation, thereby improving the accuracy of compacting the side materials to fill the side seams.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model provides side extrusion plates at both ends of the pressing plate to compact and fill the side materials, thereby effectively avoiding the problem of edge effect of the side materials due to airflow and improving the working efficiency of the sintering machine.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are conventional technical means in the art. Example

[0019] like Figure 1 and 2 The device for increasing the strength of a sintering machine is shown. It is applied to a sintering machine body 11. A trolley 5 is disposed inside the sintering machine body 11. A mounting plate 12 is connected to the top of the sintering machine body 11 via a hydraulic cylinder 10. A holding plate 8 is fixed to the bottom of the mounting plate 12 via a plurality of connecting rods 9. Two motors 13 are fixed in the middle of the bottom of the mounting plate 12.

[0020] The output end of the motor 13 is connected to a screw rod 1, and the other end of the screw rod 1 is connected to a bearing 14 and is arranged at the bottom of the mounting plate 12;

[0021] The end of the screw rod 1 away from the motor 13 is provided with a thread I15 and a thread II16 in opposite directions, and the thread I15 and the thread II16 are respectively connected to the nut I2 and the nut II17, and the bottom of the nut I2 and the nut II17 are respectively hinged to the hinge rod I3 and the hinge rod II18. The ends of the hinge rod I3 and the hinge rod II18 are hinged and connected to the top of the side extrusion plate 4.

[0022] The working principle of this embodiment is as follows:

[0023] After the material on the trolley 5 is completely burned, the hydraulic cylinder 10 is started to push the mounting plate 2 downward, thereby driving the pressure plate 8 to compact the material on the trolley 5. At this time, the material on the side of the pressure plate 8 overflows, and the motor 13 is started to rotate the screw rod 1 counterclockwise or clockwise. Since the threads Ⅰ15 and Ⅱ16 set on the screw rod 1 are in opposite directions, when the screw rod 5 rotates clockwise, the nuts Ⅰ2 and Ⅱ17 approach each other, and the horizontal position of the screw rod 5 does not change. Therefore, the horizontal positions of the nuts Ⅰ2 and Ⅱ17 do not change, so the angle between the hinge rod Ⅰ3 and the hinge rod Ⅱ18 becomes smaller, that is, the hinge rod Ⅰ3 and The hinged ends of the hinge rods Ⅱ18 move in the direction away from the mounting plate 12, that is, the side extrusion plate 4 is pressed to flatten the side material to fill the side seam; after the edge sealing is completed, the rotation direction of the motor 13 is changed to drive the screw 5 to rotate counterclockwise. At this time, the nut Ⅰ2 and the nut Ⅱ17 are away from each other, and the angle between the hinge rod Ⅰ3 and the hinge rod Ⅱ18 becomes larger, that is, the hinged ends of the hinge rod Ⅰ3 and the hinge rod Ⅱ18 move in the direction close to the mounting plate 12, driving the side extrusion plate 4 to move in the direction close to the mounting plate 12, and at the same time starting the hydraulic cylinder 10 to lift the mounting plate 12 for the next material compaction. Example

[0024] This embodiment is a further improvement made on the basis of embodiment 1, and is specifically as follows:

[0025] like Figure 3 As shown, the two ends of the pressing plate 8 are provided with "T"-shaped sliding grooves 6, and the side surfaces of the side extrusion plate 4 are provided with "T"-shaped sliding blocks 7 that match the "T"-shaped sliding grooves 6 and are movably connected.

[0026] The working principle of this embodiment is the same as that of embodiment 1. The side extrusion plate 4 is movably connected to the "T"-shaped slide groove 6 provided at both ends of the pressing plate 8 through the "T"-shaped slider 7, so that the side extrusion plate 4 only moves in the vertical direction and will not be offset in the horizontal direction, thereby improving the accuracy of compacting the edge material to fill the edge seam.

The scope of protection of the present invention is defined by the claims. Persons skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
