Description

Technical Field

[0001] This utility model relates to the technical field of sintering machines, and in particular to a sintering machine. Background Technology

[0002] Sintering machines are suitable for sintering operations in large-scale ferrous metallurgical sintering plants, primarily for the sintering of iron ore powder in large and medium-sized plants. It is the main equipment in the ducted sintering process, capable of sintering concentrates and rich ore powders of different compositions and particle sizes into blocks, and partially eliminating harmful impurities such as sulfur and phosphorus contained in the ore. Sintering machines are available in several specifications based on sintering area, varying in length and width, allowing users to select the appropriate machine based on their production capacity or site conditions. Larger sintering areas result in higher output.

[0003] The prior art can be referenced from Chinese authorized utility model patent with publication number CN221223328U, which specifically describes a low-carbon sintering machine, including: a mixing box, a sintering machine body, and an air guide pipe. The lower surface of the sintering machine body is welded with support legs, and a partition is embedded and fixed in the inner wall of the sintering machine body. A fan is installed on the upper surface of the sintering machine body, and a suction hood is connected to the lower surface of the fan. The suction hood is connected to the sintering machine body. A blowing pipe is connected to one outer end face of the fan, and the blowing pipe passes through the sintering machine body and the air guide pipe. An electric heating wire is embedded and fixed in the inner wall of the blowing pipe. The air guide pipe is fixed in the inner wall of the sintering machine body, and an air outlet pipe is connected to the lower surface of the air guide pipe. A discharge pipe is connected to one outer end face of the mixing box, and a fixed pipe is connected to one outer end face of the discharge pipe. A connecting pipe is connected to one outer end face of the fixed pipe. This existing technology, by setting up a fan, air duct, and casing, achieves the effect of meeting the heat required for sintering while reducing carbon consumption and reducing environmental pollution from CO2 generation. The fan, driven by a power unit, draws in air through an suction hood and then sends the gas into the blowing duct. The heating wire, driven by the power unit, heats the gas. The gas becomes hot air after passing through the heating wire and enters the air duct, then is blown out through the exhaust duct. The exhaust duct has three paths (left, middle, and right) for sintering the mixture. The casing, driven by a power unit, blows air, and the heating wire, driven by the power unit, heats the air. The air is blown out through a hot air hood, and the hot air and hot air form convection. This can meet the heat required for sintering while reducing carbon consumption, reducing environmental pollution from CO2 generation, and ensuring the quality and output of the sintered ore.

[0004] The aforementioned prior art has the following shortcomings in actual operation: In actual use, the raw materials that slide out from the connecting pipe and fall onto the surface of the partition accumulate on the left side of the partition. Due to the uneven thickness of the raw materials, the sintering time required is different, resulting in a lower sintering speed for the accumulated raw materials and higher operating costs for the sintering machine.

[0034] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Given that in the current technology, in actual use, the raw materials that slide out of the connecting pipe and fall onto the surface of the partition accumulate on the left side of the partition, and because the thickness of the raw materials is uneven, the sintering time required is different, the sintering speed of the accumulated raw materials is low, and the operating cost of the sintering machine is high.

[0037] like Figure 1-7 As shown, this utility model embodiment provides a sintering machine, which includes an outer casing 1, a mixing mechanism 2, and a smoothing mechanism 3, among other parts.

[0038] The partition 301 is connected to the lower part of the inner wall of the outer box 1. An electric telescopic tube 304 is provided at the center of the partition 301. A squeegee 307 is connected to the upper right of the electric telescopic tube 304. A spacer ring 305 is connected to the center of the surface of the electric telescopic tube 304. A rotating groove 306 is opened at the top of the partition 301. The inner wall of the rotating groove 306 is rotatably connected to the side of the spacer ring 305.

[0039] Specifically, the smoothing mechanism 3 also includes a protective box 302 and a second motor 303 (model SGM7G-1A6A).

[0040] The top of the protective box 302 is connected to the bottom of the partition 301, the bottom of the second motor 303 is connected to the bottom of the inner wall of the protective box 302, and the output shaft of the second motor 303 is connected to the bottom of the electric telescopic tube 304 (model CeramTec HT-800). The telescopic height of the electric telescopic tube 304 is adjusted according to the amount of raw materials put in.

[0041] Specifically, the smoothing mechanism 3 also includes a discharge port 308 and a fixing block 310.

[0042] The discharge port 308 is located on the top left and right sides of the partition plate 301. The side of the discharge port 308 has a movable cavity 309. The fixed block 310 is connected to the inner wall of the movable cavity 309. A bidirectional hydraulic rod 311 (model Bosch Rexroth R4) is connected to the center of the fixed block 310. Both ends of the bidirectional hydraulic rod 311 are connected to a blocking plate 312. The surface of the blocking plate 312 is slidably connected to the inner wall of the movable cavity 309.

[0043] In use, after the raw material falls onto the surface of the partition 301, the electric telescopic tube 304 extends and retracts to adjust the smearing plate 307 to a suitable height. The output shaft of the second motor 303 inside the protective box 302 rotates, driving the electric telescopic tube 304 to rotate. The rotation of the electric telescopic tube 304 drives the spacer ring 305 to rotate in the rotating groove 306, and at the same time drives the smearing plate 307 to rotate, pushing and flattening the accumulated raw material. The extension and retraction of the electric telescopic tube 304 cuts the raw material into blocks and drives the smearing plate 307 to keep its bottom in contact with the upper surface of the partition 301. After the raw material is sintered, the bidirectional hydraulic rod 311 connected to the fixed block 310 in the movable cavity 309 shortens, causing the blocking plate 312 to move towards each other and expose the discharge port 308. The output shaft of the second motor 303 rotates, driving the electric telescopic tube 304 to rotate. The rotation of the electric telescopic tube 304 drives the smearing plate 307 to rotate, pushing the sintered block to move and fall from the discharge port 308.

[0044] Furthermore, to prevent material from flowing out during the sintering process, the sintering machine also includes an outer casing 1.

[0045] Specifically, such as Figure 1-2 As shown, the outer casing 1 includes a support frame 101 and a top cover 105.

[0046] The support frame 101 is connected to the box 102 on one side. The lower part of the inner wall of the box 102 is connected to the arc surface of the partition 301. The bottom of the box 102 is connected to the discharge pipe 103. The right side of the discharge pipe 103 is connected to the solenoid valve 104 (model Burkert 6012). The bottom of the top cover 105 is snapped into the top of the box 102. The left side of the top of the top cover 105 is connected to the feed pipe 106.

[0047] In use, the raw materials are poured into the box 102 connected to the support frame 101 by the feed pipe 106 at the top of the top cover 105. The solenoid valve 104 controls the discharge pipe 103 to be in the open state, and the sintered blocks falling from the discharge port 308 are discharged along the discharge pipe 103.

[0048] Furthermore, in order to ensure that the raw materials are stirred evenly and fully mixed, the sintering machine also includes a mixing mechanism 2.

[0049] Specifically, such as Figure 2-4 As shown, the mixing mechanism 2 includes an arc-shaped plate 201 and a conical bucket 206.

[0050] Among them, the bottom of the arc plate 201 is connected to the rear side of the top of the top cover 105, the front side of the arc plate 201 is connected to the first motor 202 (model SGM7G-1A6A), the output shaft of the first motor 202 is connected to the rotating rod 203, the side of the rotating rod 203 is connected to the mixing plate 204, the side of the mixing plate 204 is connected to the scraper 205, and the side of the conical bucket 206 is connected to the upper part of the inner wall of the box 102.

[0051] Specifically, the mixing mechanism 2 also includes a discharge hopper 207 and a connecting frame 208.

[0052] The top of the discharge hopper 207 is connected to the bottom of the conical hopper 206, the right side of the connecting frame 208 is connected to the bottom right side of the discharge hopper 207, and the top left side of the connecting frame 208 is connected to an electric push rod 209 (model TA36P-HT). The top of the electric push rod 209 is connected to a block 210, and the outer surface of the block 210 is in contact with the inner wall of the discharge hopper 207.

[0053] In use, the output shaft of the first motor 202 connected to the arc plate 201 rotates, driving the rotating rod 203 to rotate. The rotating rod 203 rotates, driving the mixing plate 204 to rotate. The rotation of the mixing plate 204 drives the raw materials to be fully stirred and mixed. After the mixing is completed, the electric push rod 209 connected to the connecting frame 208 shortens, causing the block 210 to move down. The rotation of the mixing plate 204 drives the scraper 205 to rotate, scraping the raw materials above the inner wall of the box 102 and the upper surface of the conical hopper 206, causing them to fall down between the discharge hopper 207 and the outer surface of the block 210, landing on the surface of the partition plate 301.

[0054] Furthermore, in order to sinter concentrates and rich mineral powders of different compositions and particle sizes into blocks, the sintering machine also includes a sintering mechanism 4.

[0055] Specifically, as shown in Figures 1-5, the sintering mechanism 4 includes an air inlet pipe 401 and a heating box 403.

[0056] The air inlet pipe 401 is connected to the lower left of the housing 102 on the right side. A fan 402 (model Howden SHR-400) is connected to the right side of the inner wall of the air inlet pipe 401. The bottom of the heating box 403 is connected to one end of the air inlet pipe 401. An electric heating wire 404 (model Kanthal A1-1000) is connected to the inner wall of the heating box 403. The solenoid valve 104, the first motor 202, the electric push rod 209, the second motor 303, the electric telescopic tube 304, the bidirectional hydraulic rod 311, the fan 402, and the electric heating wire 404 are all controlled by an external controller.

[0057] Specifically, the sintering mechanism 4 also includes an exhaust pipe 405 and an annular pipe 406.

[0058] Among them, the exhaust pipe 405 is connected to the top of the heating box 403, one end of the exhaust pipe 405 is connected to the lower left side of the box 102, the side of the annular pipe 406 is connected to the lower inner wall of the box 102, and the other side of the annular pipe 406 is evenly connected to the exhaust pipe 407.

[0059] In use, the blower 402 drives the hot air in the box 102 to be transported to the heating box 403 through the air inlet pipe 401. After being heated by the electric heating wire 404, the hot air is blown towards the raw material through the exhaust pipe 407 on the surface of the annular pipe 406 connected to the air outlet pipe 405 for sintering. At the same time, the hot air blown out from different directions forms convection to reduce carbon consumption.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
