Description

Technical Field

[0001] This utility model relates to the technical field of sintering mixers, specifically to an intelligent mixing system for sintering mixers. Background Technology

[0002] The sintering machine is one of the main equipment for supplying raw materials to blast furnaces and plays a vital role in industry. Its main function is to complete the charging, ignition, and sintering on the track and discharge the sintered ore from the tail end. The internal structure of the belt sintering machine includes a trolley, a tail star wheel, and a moving frame. It requires the cooperation of an electric furnace during operation. During normal iron ore powder sintering, the fuel and raw materials in the mixing trough and the bottom material trough are respectively added into the sintering machine for combustion and refining through a round roller feeder and a roller distributor. The electric furnace usually ignites the material by igniting gas.

[0003] However, during the operation of the sintering machine, there are often deviations in material distribution. Fuels such as coke powder may be unevenly distributed on the material surface, resulting in uneven temperature and airflow distribution during the sintering process. This uneven material distribution will reduce the utilization efficiency of fuel, thereby affecting the effect of the sintering process and the quality of the sintered ore.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing intelligent mixing system for sintering mixers. Therefore, we propose that the intelligent mixing system for sintering mixers can effectively solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent mixing system for a sintering mixer, in order to solve the problem mentioned in the background art that the material distribution in the current sintering machine operation is often biased, and the fuel such as coke powder may be unevenly distributed on the material surface, resulting in uneven temperature and airflow distribution during the sintering process. This uneven material distribution will lead to a reduction in fuel utilization efficiency, thereby affecting the effect of the sintering process and the quality of the sintered ore.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent mixing system for a sintering mixer, comprising a support frame, a material silo mounted on the support frame, and a discharge pipe disposed below the material silo. The system is characterized in that a storage box is mounted on the support frame, a second rotating shaft is connected through the storage box, the second rotating shaft is connected through the discharge pipe, and a conveying component is disposed outside the second rotating shaft, the conveying component being located inside the discharge pipe.

[0007] Preferably, the storage box is equipped with a first motor, the output end of the first motor is connected to a first rotating shaft, and the first rotating shaft is connected to a second rotating shaft through a driving component.

[0008] Preferably, the material silo is provided with a stirring assembly, which includes a second motor installed on the material silo.

[0009] Preferably, the output end of the second motor is connected to a rotating rod, which is connected through the inside of the material bin.

[0010] Preferably, the rotating rod is provided with a stirring element and a scraper on its outer side. The scraper is in contact with the inner wall of the material bin. The output end of the second motor drives the rotating rod to rotate inside the material bin. The stirring element provided on the outer side of the rotating rod facilitates the mixing of coke powder inside the material bin. The stirring element can fully stir the coke powder in the material bin, so that the coke powder is evenly distributed and the coke powder quality is consistent.

[0011] Preferably, an eccentric wheel is provided on the outer side of the first rotating shaft, and a movable frame is installed on the outer side of the eccentric wheel. The side end of the movable frame is connected to a storage frame through a movable rod. When the eccentric wheel on the outer side of the first rotating shaft rotates, it drives the outer movable frame to move laterally. This facilitates the movable frame to drive the storage frame to move laterally through the movable rod. The whole is driven by the same motor, which reduces the problem of increased cost caused by setting up additional drives.

[0012] Preferably, the storage frame is located at the lower end of the feeding pipe, and a sieve plate is provided inside the storage frame. The lateral movement of the storage frame drives the sieve plate to move. The sieve plate can not only screen the output coke powder to remove large particles or lumps and improve the quality of sintered products, but also facilitate the movement and scattering of the screened coke powder, ensuring the uniformity of the coke powder on the sintering machine.

[0013] Preferably, a limiting rod is installed on the other side of the storage frame, and a limiting seat is installed on the bracket, with the limiting rod passing through the inside of the limiting seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This intelligent mixing system for sintering mixers uniformly adds coke powder to the upper end of the sintering machine through the feeding pipe at the bottom of the material silo. The first motor inside the storage tank is activated, driving the first rotating shaft to rotate. The first rotating shaft, through a drive component, drives the second rotating shaft to rotate, causing the second rotating shaft to drive the conveyor component to rotate stably inside the feeding pipe. This effectively controls the feeding speed and flow rate of the coke powder, avoiding blockages or uneven feeding, and ensuring a uniform and stable material supply to the sintering machine. The specific details are as follows:

[0015] (1) Coke powder is evenly added to the upper end of the sintering machine through the feeding pipe at the bottom of the material silo. The first motor drives the first rotating shaft to rotate. The first rotating shaft drives the second rotating shaft to rotate through the driving component, so that the second rotating shaft drives the conveying component to rotate stably inside the feeding pipe, thereby effectively controlling the feeding speed and flow rate of coke powder and ensuring that the sintering machine receives a uniform and stable material supply.

[0016] (2) The output end of the second motor drives the rotating rod to rotate inside the material bin. The stirring element set on the outside of the rotating rod facilitates the mixing of coke powder inside the material bin. The stirring element can fully stir the coke powder in the material bin, so that the coke powder is evenly distributed and the coke powder quality is consistent.

[0017] (3) The scraper on the outside of the rotating rod can not only prevent coke powder from adhering to the inner wall of the material bin, avoid material accumulation, ensure the effective use of the internal space of the material bin, further improve the coke powder mixing effect and conveying efficiency, but also facilitate the later cleaning operation and improve the overall maintenance effect.

[0018] (4) The eccentric wheel on the outer side of the first rotating shaft rotates, so that the eccentric wheel drives the outer moving frame to move laterally, which facilitates the moving frame to drive the storage frame to move laterally through the moving rod. The whole is driven by the same motor, which reduces the problem of increased cost caused by setting up additional drives.

[0019] (5) The horizontal movement of the storage frame drives the screen plate to move. The screen plate can not only screen the output coke powder, remove large particles or lumps in the coke powder, and improve the quality of sintered products, but also facilitate the movement and scattering of the screened coke powder, ensuring the uniformity of the coke powder on the sintering machine.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: In this example, the second rotating shaft 8 drives the conveying component 9 to rotate stably inside the feeding pipe 3, thereby effectively controlling the feeding speed and flow rate of coke powder, avoiding blockages or uneven feeding, and ensuring a uniform and stable material supply to the sintering machine. Figures 1-4 The technical solution shown includes a support frame 1, a material silo 2 mounted on the support frame 1, a feeding pipe 3 below the material silo 2, a storage box 4 mounted on the support frame 1, a second rotating shaft 8 penetrating the storage box 4 and connected inside the feeding pipe 3, a conveying component 9 located outside the second rotating shaft 8 inside the feeding pipe 3, a first motor 5 inside the storage box 4, and a first rotating shaft 6 connected to the output of the first motor 5. The first rotating shaft 6 is connected to the second rotating shaft 8 via a drive component 7. The material silo 2 is positioned at the top of the sintering machine via the support frame 1. The coke powder to be burned is then transported to the material silo 2 via a sealed tanker truck. The coke powder is evenly added to the upper part of the sintering machine through the feeding pipe 3 at the bottom of the material bin 2. The first motor 5 inside the storage box 4 is turned on, and the first motor 5 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the second rotating shaft 8 to rotate through the driving component 7. The driving component 7 of this application is a vertically set bevel gear structure, which facilitates the conversion of vertical rotation into horizontal rotation. The driving component 7 can realize efficient power transmission and precise conversion of rotation direction, so that the second rotating shaft 8 drives the conveying component 9 to rotate stably inside the feeding pipe 3, thereby effectively controlling the feeding speed and flow of coke powder, avoiding blockage or uneven feeding, and ensuring that the sintering machine receives a uniform and stable material supply.

[0030] Example 2: In this example, the scraper 13 not only prevents coke powder from adhering to the inner wall of the material bin 2, avoiding material accumulation and ensuring the effective utilization of the internal space of the material bin 2, further improving the coke powder mixing effect and conveying efficiency, but also facilitates subsequent cleaning operations, improving the overall maintenance effect. Specifically, as follows... Figures 1-3 As shown, a stirring assembly is installed on the material silo 2. The stirring assembly includes a second motor 10 installed on the material silo 2. The output end of the second motor 10 is connected to a rotating rod 11, which runs through the inside of the material silo 2. An agitator 12 and a scraper 13 are installed on the outside of the rotating rod 11. The scraper 13 is in contact with the inner wall of the material silo 2. When the second motor 10 is turned on, the output end of the second motor 10 drives the rotating rod 11 to rotate inside the material silo 2. The agitator 12 installed on the outside of the rotating rod 11 facilitates the mixing of coke powder inside the material silo 2. The agitator 12 can fully stir the coke powder in the material silo 2, making the coke powder evenly distributed and ensuring the consistency of coke powder quality. In addition, the scraper 13 installed on the outside of the rotating rod 11 can not only prevent coke powder from adhering to the inner wall of the material silo 2 and avoid material accumulation, but also ensure the effective use of the internal space of the material silo 2, further improving the coke powder mixing effect and conveying efficiency. Moreover, it facilitates subsequent cleaning operations and improves the overall maintenance effect.

[0031] Example 3: In this example, the sieve plate 18 not only screens the output coke powder, removing large particles or clumps to ensure the particle size of the coke powder entering the sintering machine meets process requirements and improves the quality of the sintered product, but also facilitates the movement and dispersion of the screened coke powder, ensuring the uniformity of the coke powder on the sintering machine. Specifically, as shown... Figures 3-7As shown, an eccentric wheel 14 is provided on the outer side of the first rotating shaft 6, and a movable frame 15 is installed on the outer side of the eccentric wheel 14. A storage frame 17 is connected to the side end of the movable frame 15 through a movable rod 16. The storage frame 17 is located at the lower end of the feeding pipe 3. A screen plate 18 is provided inside the storage frame 17. A limit rod 19 is installed on the other side of the storage frame 17, and a limit seat 20 is installed on the bracket 1. The limit rod 19 is connected through the limit seat 20. When the first rotating shaft 6 rotates, the eccentric wheel 14 on the outer side of the first rotating shaft 6 rotates, so that the eccentric wheel 14 drives the outer movable frame 15 to move laterally, so that the movable frame 15 drives the storage frame 17 to move laterally through the movable rod 16. When the feeding pipe 3 outputs coke powder, the screen plate 18 inside the storage frame 17 receives the coke powder. The whole is driven by the same motor. The drive reduces the cost increase caused by setting up additional drives. At this time, the horizontal movement of the placement frame 17 drives the screen plate 18 to move. The screen plate 18 can not only screen the output coke powder, remove large particles or lumps from the coke powder, and ensure that the particle size of the coke powder entering the sintering machine meets the process requirements and improve the quality of sintered products, but also facilitate the movement and dispersion of the screened coke powder, ensuring the uniformity of the coke powder on the sintering machine. In addition, the other end of the placement frame 17 moves stably within the limit seat 20 through the limit rod 19, ensuring the stability and accuracy of the movement of the placement frame 17, making the screening process more reliable. The overall structure is simple, reducing the problem of increased maintenance costs caused by setting up complex structures.
