Description

Technical Field

[0001] The invention relates to the technical field of preheating furnace structures, in particular to a continuous preheating furnace mechanism for a sintering machine. Background Art

[0002] Sintering machines are a type of equipment used to supply raw materials to blast furnaces, primarily used in large-scale ferrous metallurgical sintering plants. They can agglomerate concentrates and enriched ore of varying composition and particle size into agglomerates, partially eliminating harmful impurities such as sulfur and phosphorus from the ore. To improve sintering efficiency, preheating the mining materials is necessary during calcination.

[0003] The existing Chinese patent application with application publication number CN116625126A discloses a sintered ore preheating and bottom material flattening device, which includes a mounting frame, a preheating mechanism, a dismantling mechanism and a cleaning mechanism. A sintering trolley is provided at the bottom of the mounting frame, a feed box is provided at the top of the mounting frame, and a scraper is provided on the outside of the sintering trolley; the preheating mechanism includes a first preheating pipe and a second preheating pipe rotatably provided inside the feed box, and the first preheating pipe and the second preheating pipe are both provided with multiple sets of air outlet pipes and protective covers located at the outer ends of the air outlet pipes. The multiple sets of air outlet pipes are used to stir the mixed material while The preheating effect is achieved at the same time; the disassembly mechanism includes a movable groove provided on the feed box, and the first preheating tube and the second preheating tube are provided with a first movable frame near the movable groove, and the first movable frame can take the first preheating tube and the second preheating tube out of the feed box for maintenance through the movable groove; the invention, by setting a preheating mechanism, can achieve stirring of the mixture, and high-temperature steam can be transported into the first preheating tube and the second preheating tube during stirring, and the high-temperature steam is sprayed onto the mixture from multiple groups of exhaust pipes, so that the mixture can be preheated while being stirred, thereby improving the preheating effect of the mixture.

[0004] However, the sintering machine preheating mechanism has the following defects when used:

[0005] 1. The existing sintering machine preheating mechanism needs to stir the mining materials to ensure the efficiency of preheating the mining materials. At the same time, during the transportation of the mining materials, the mining materials will stick together due to the moisture in the mine. At this time, it will be difficult to stir the mining materials to move or cause the stirred mining materials to fall. Therefore, it is necessary to crush the stirred mining materials during transportation. However, when the mining materials are crushed, some of the material debris will adhere to the surface of the crushing parts, causing the adhered material debris to splash during the rotation and crushing process.

[0006] 2. After preheating the mineral materials, existing preheating mechanisms need to stir the materials to improve the preheating effect. However, during this stirring process, the transferred mineral materials will bulge. When subsequently transferred to the sintering machine for sintering, the mineral materials may be unevenly distributed, resulting in incomplete sintering or over-sintering. Summary of the Invention

[0040] Wherein, a heating system is provided inside the rolling roller, and the heating system heats the mining material.

[0041] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0042] 1. In the continuous preheating furnace mechanism of the sintering machine, when preheating the mining materials to improve the efficiency of subsequent sintering, the driving shaft that drives the conveyor belt to transport the mining materials for loading will simultaneously drive the cutting shaft and cutting blades to rotate, continuously cutting and crushing the mining materials on the top of the conveyor belt, so that the mining materials that stick together can be automatically separated. At the same time, this ensures that when the mining materials are subsequently preheated through the preheating module and preheating tube, the contact range between the mining materials (after cutting and crushing) and the hot air generated by the preheating tube is increased, thereby improving the efficiency and effectiveness of the mining material preheating process.

[0043] 2. In the continuous preheating furnace mechanism for the sintering machine, when the mining materials are cut and crushed by the cutting blades, some mining debris will adhere to the surface of the cutting blades. At this time, the cleaning port inside the T-shaped cleaning cover can automatically separate the debris on the cutting blade surface that moves to the inside of the cleaning port, reducing the probability of debris accumulation on the cutting blade surface. At the same time, the cutting shaft that drives the cutting blade to rotate can synchronously drive the collision rod to move up and down (reciprocating) when rotating, and continuously vibrate and collide the T-shaped cleaning cover that removes the debris on the cutting blade surface, reducing the probability of debris adhesion and accumulation in the cleaning port inside the T-shaped cleaning cover, and ensuring that the T-shaped cleaning cover can continuously clean the debris on the cutting blade surface. In addition, the cleaned debris will fall back to the top of the conveyor belt, reducing the problem of splashing or waste of mining materials (debris);

[0044] 3. In the continuous preheating furnace mechanism of the sintering machine, when preheating the mining materials, the mining materials need to be cut, crushed and blasted. At this time, the mining materials on the top of the conveyor belt will be partially bulged or sunken. At this time, the force of the conveyor belt (the rotation of the driven shaft) can drive the rolling roller to rotate continuously, rolling the mining materials after preheating. This ensures that the mining materials on the top of the conveyor belt are highly consistent and more uniform when they are transported to the interior of the sintering machine. This will prevent the problems of incomplete sintering or over-sintering during the subsequent sintering process of the mining materials.

[0045] 4. In the continuous preheating furnace mechanism for the sintering machine, when the mining materials are being transported and loaded, the torque provided by the driving motor during the transport and loading process can be used to simultaneously cut and crush the mining materials, clean the surface of the cut and crushed parts, and roll the mining materials after preheating. This integrates various pretreatment operations for the mining materials to ensure the subsequent sintering effect of the mining materials. BRIEF DESCRIPTION OF THE DRAWINGS

The front bracket 10 is arranged on the side of the rear bracket 20. The top of the front bracket 10 and the rear bracket 20 are fixed with the protective frame 30 by screws. The outer side of the protective frame 30 is provided with an integrated conveying and pressing mechanism 40 extending to the inner side and top of the protective frame 30.

The preheating furnace 302 is fixed to the top of the protective frame 30 by screws. The upper frame 301 and the preheating furnace 302 are internally provided with an integrated conveying and pressing mechanism 40, wherein the integrated conveying and pressing mechanism 40 includes a leather Belt conveyor assembly 50, the belt conveyor assembly 50 is installed inside the protective frame 30, mining materials are transported on the top of the belt conveyor assembly 50, the belt conveyor assembly 50 extends to the outside of the protective frame 30, a transmission cutting assembly 60 is installed on one side of the belt conveyor assembly 50, the transmission cutting assembly 60 extends to the inside of the upper frame 301, a reciprocating collision assembly 70 is installed on the outside of the transmission cutting assembly 60, the reciprocating collision assembly 70 is located on one side of the bottom of the transmission cutting assembly 60; transmission rolling assembly 80, the transmission rolling assembly 80 is connected to the belt conveyor assembly 50, the transmission rolling assembly 80 extends to the inside of the preheating furnace 302, and the transmission rolling assembly 80 is located on the side of the transmission cutting assembly 60.

[0070] The operating principle described above is as follows: During the sintering process (through the sintering machine), the mineral materials need to be preheated. The mineral materials are then poured onto the top of the belt conveyor assembly 50, where they are transported and loaded into the feed section of the sintering machine. Simultaneously, the operation of the belt conveyor assembly 50 drives the transmission cutting assembly 60 to cut and crush the transported mineral materials, reducing their bulk. This improves the efficiency of preheating the mineral materials when they are subsequently transported to the preheating tube 3023 and preheating module 3022 for preheating. Furthermore, the operation of the belt conveyor assembly 50 also drives the transmission pressing assembly 80 to press the preheated and cut and crushed mineral materials, ensuring a consistent thickness and height of the mineral materials upon delivery to the sintering machine. This prevents problems such as incomplete or over-sintering during sintering of the mineral materials in the sintering machine.

[0071] In the present invention, the transmission cutting assembly 60 can drive the reciprocating collision assembly 70 to operate during operation, and vibrate the coal mine debris adhering to the surface of the transmission cutting assembly 60 to ensure that the adhering coal mine debris can fall on the top of the belt conveyor assembly 50 for transportation.

[0072] Specific reference Figure 7 The belt conveyor assembly 50 includes a driving motor 501, which is installed inside the rear bracket 20 by screws.

[0074] In the continuous preheating furnace mechanism for a sintering machine of the present invention, when conveying and loading mining materials, the drive motor 501 is activated, driving the main shaft 502 connected to the output end of the drive motor 501 to rotate. This causes the drive belt 503, which is connected to the outside of the main shaft 502 via a synchronous pulley, to operate. The operation of the drive belt 503 drives the drive shaft 504, which is connected to the inside of the drive belt 503 via a synchronous pulley key, to rotate. This causes the conveyor chain 506, which is connected to the outside of the drive shaft 504 via a conveyor sprocket 505, to operate. As the conveyor chain 506 operates, the conveyor belt 5061 installed inside it can also operate to convey and load the mining materials on top of the conveyor belt 5061.

[0075] Specific reference Figure 10 The transmission cutting assembly 60 includes a first transmission belt 601, which is connected to the outer side of the driving shaft 504 through a synchronous wheel key provided on the inner side. The first transmission belt 601 is movably provided on the outer side of the protective frame 30, and the first transmission belt 601 is provided away from the driving belt 503; a transmission shaft 602, which is connected to the inner side of the first transmission belt 601 through a synchronous wheel key provided on the inner side.

[0077] In the above embodiment, when the cutting blade 605 rotates to cut and crush the mining material, the mining debris adhered to the surface of the cutting blade 605 will move to the side of the cleaning port 6042 following the rotation of the cutting blade 605, and the cleaning port 6042 will squeeze the debris, so that the mining debris adhered to the surface of the cutting blade 605 can be removed from the surface of the cutting blade 605, and the rotational force of the cutting blade 605 will not cause the mining debris to splash.

[0078] In the continuous preheating furnace mechanism for a sintering machine according to the present invention, when the drive shaft 504 rotates, the first transmission belt 601, connected to its outer side via a synchronous pulley, operates, causing the transmission shaft 602, connected to its inner side via a synchronous pulley, to rotate. The rotation of the transmission shaft 602, in turn, causes the second transmission belt 603, connected to its outer side via a synchronous pulley, to operate, causing the cutting shaft 604, connected to its inner side via a synchronous pulley, to rotate. The rotation of the cutting shaft 604 drives the cutting blade 605 mounted on its outer side to rotate, cutting and crushing the mining material disposed at the base of the cutting blade 605.

[0079] Specific reference Figure 10 and Figure 11 The reciprocating collision assembly 70 includes a first gear 701, which is provided with two first gears 701, and the two first gears 701 are meshed and connected. The two first gears 701 are rotatably connected to the side of the upper frame 301, and the two first gears 701 are set on the side of the second transmission belt 603. One first gear 701 is installed on the outside of the cutting shaft 604; a rotating disk 702, which is installed on the shaft end of another first gear 701, and the rotating disk 702 is movably set on the side of the upper frame 301. A protrusion 703 is installed at the eccentric point of the rotating disk 702; a connecting arm 704, which is rotatably connected to the outside of the protrusion 703, and the inner side of the connecting arm 704 is rotatably connected to the side convex rod 705, and the outer side of the side convex rod 705 is rotatably connected to the lifting block 706, and the lifting block 706 is slidably connected to the outside of the one-way rod 707, and the one-way rod 707 is installed on the side of the upper frame 301.

[0080] In this embodiment, a collision rod 7061 is installed on one side of the top of the lifting block 706 by screws, and the top of the collision rod 7061 is in contact with a lower collision block 7062, wherein the lower collision block 7062 is installed on one side of the bottom of the T-shaped cleaning cover 6041.

[0081] In the continuous preheating furnace mechanism for a sintering machine according to the present invention, when the cutting shaft 604 rotates, it drives the first gear 701 mounted on its outer side to rotate, causing another first gear 701 meshed with the side of the first gear 701 to rotate. When the other first gear 701 rotates, the rotating disk 702 connected to its shaft end rotates, causing the connecting arm 704, which is rotatably connected to the eccentric outer side of the rotating disk 702 via the protrusion 703, to operate. This allows the side protrusion 705 and the lifting block 706, which are rotatably connected to the inner side of the connecting arm 704, to move upward and downward on the outer side of the one-way rod 707. When the lifting block 706 moves upward and downward (reciprocating), the collision rod 7061 mounted on its top also moves upward and downward, colliding with the lower collision block 7062 and T-shaped cleaning cover 6041, which the top of the collision rod 7061 contacts.
