Description

Technical Field

[0001] This utility model relates to the technical field of slag discharge devices for furnace slag coolers, specifically a slag discharge speed adjustment device for furnace slag coolers. Background Technology

[0002] In industrial production, a furnace slag cooler is a key piece of equipment for handling high-temperature slag. Slag is a solid waste produced during the production processes of metallurgy, chemical industry, and other sectors, resulting from the reaction of ores, fuels, and other materials at high temperatures. The main function of the furnace slag cooler is to rapidly cool and discharge the high-temperature slag to ensure the continuity and stability of the production process. Controlling the slag discharge rate is crucial for the normal operation of the furnace slag cooler. A suitable discharge rate ensures timely slag removal, preventing slag accumulation within the furnace slag cooler and avoiding equipment overheating and damage caused by slag buildup. It also ensures the smooth operation of subsequent production stages. If the discharge rate is too fast, the slag may not cool sufficiently, affecting subsequent processing and utilization; conversely, if the discharge rate is too slow, the slag will remain in the furnace slag cooler for too long, increasing the equipment load and reducing production efficiency. Therefore, a device capable of precisely adjusting the slag discharge rate of the furnace slag cooler is needed to meet the requirements of different production conditions.

[0003] Traditional slag discharge speed regulation technology for furnace coolers has many drawbacks. Some traditional methods rely heavily on manual experience, adjusting valves or baffles to change the size of the slag discharge channel and thus regulate the discharge speed. This method not only has low precision but also struggles with real-time, dynamic adjustment, failing to meet the precise control requirements of slag discharge speed during production. Furthermore, the regulating devices in traditional technologies are complex in structure and have poor reliability. Due to prolonged exposure to high temperatures and harsh working environments, components of traditional regulating devices are prone to wear and corrosion, leading to frequent malfunctions or failures. This not only increases equipment maintenance costs and downtime but also severely impacts normal production. Simultaneously, traditional regulation technology has poor adaptability to slag; when slag properties change, it is difficult to adjust the discharge speed promptly, easily resulting in poor slag treatment and further affecting the efficiency and quality of the entire production process. Therefore, developing a novel slag discharge speed regulation device for furnace coolers is of significant practical importance. To this end, we propose a slag discharge speed regulation device for furnace coolers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a slag discharge speed adjustment device for a furnace slag cooler, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a slag discharge speed adjustment device for a furnace slag cooler, comprising a slag discharge cylinder, an adjustment cylinder fixedly connected to the outer wall of the slag discharge cylinder near the bottom, a rotating disk movably connected to the bottom of the inner wall of the adjustment cylinder, six oblique adjustment grooves evenly distributed in a ring on the top of the rotating disk, an adjustment block inserted into one end of the inner wall of the oblique adjustment groove, the output end of the adjustment block located on the upper surface of the rotating disk, a limit slide rail opened at the bottom of the slag discharge cylinder, and the top output end of the adjustment block slidingly connected to the top of the inner wall of the limit slide rail.

[0006] Preferably, a gear ring is fitted onto the outer wall of the rotating disk, a bracket is fixedly connected to one side of the outer wall of the slag discharge cylinder, a forward and reverse motor is fixedly connected to the top side of the bracket, the bottom rotating shaft of the forward and reverse motor extends to the bottom of the bracket, a gear is fixedly connected to the bottom rotating shaft of the forward and reverse motor, and the gear and the gear ring are meshed.

[0007] Preferably, the bottom of the regulating cylinder is provided with a slag discharge port, and the top of the slag discharge port extends to the top of the rotating disk.

[0008] Preferably, the bottom of the slag discharge cylinder is provided with a slag discharge port near the limiting slide, and the slag discharge port is parallel to the slag discharge port vertically.

[0009] Preferably, a servo motor is fixedly connected to one side of the outer wall of the slag discharge cylinder, the rotating shaft of the servo motor extends to one side of the inner wall of the slag discharge cylinder, a stirring roller is fixedly connected to the rotating shaft of the servo motor, and the stirring roller is movably connected to one end of the inner wall of the slag discharge cylinder by a connecting shaft on the side away from the servo motor.

[0010] Preferably, the stirring roller is located directly above the slag outlet.

[0011] Preferably, a fixing ring is welded to the top of the slag discharge cylinder, and four mounting heads are provided on the outer wall of the fixing ring in a ring-shaped and equidistant arrangement.

[0012] Compared with the prior art, this utility model provides a slag discharge speed regulating device for a furnace cooler, which has the following beneficial effects:

[0013] 1. The slag discharge speed adjustment device of this furnace slag cooler differs from traditional furnace slag cooler slag discharge speed adjustment technologies, which largely rely on manual experience and control the size of the slag discharge channel by manually adjusting valves or baffles. This method has low adjustment precision, making real-time and dynamic adjustment difficult, resulting in unstable slag discharge speed and affecting production continuity. In contrast, this furnace slag cooler slag discharge speed adjustment device uses a forward and reverse motor to drive gears and a gear ring, which in turn rotates a rotating disk. This causes the adjusting block to move within an inclined adjusting groove, precisely changing the cross-sectional area of ​​the slag discharge channel, thereby achieving precise adjustment of the slag discharge speed. Regardless of changes in production conditions, it can quickly and accurately adjust the slag discharge speed to the optimal state, effectively avoiding problems such as slag accumulation and equipment overheating caused by improper slag discharge speed. This significantly improves production stability and reliability, reduces downtime and malfunctions during production, and ensures smooth production operation.

[0014] 2. Compared to traditional slag discharge speed regulation devices, this furnace slag cooler's slag discharge speed regulation device is complex in structure and has numerous components. Operating in a high-temperature, harsh environment, it is prone to wear and corrosion, leading to frequent malfunctions and increased maintenance costs and downtime. This device employs a simple yet efficient structural design, with tight coordination and smooth operation between components. For example, the connection between the regulating cylinder and the slag discharge cylinder is reasonable, the moving connection of the rotating disc is stable, and the sliding fit between the regulating block and the limit slide is precise, making the overall operation of the device more reliable. Furthermore, key components such as the forward and reverse motors and servo motors are all high-quality products with excellent high-temperature and corrosion resistance, enabling long-term stable operation in harsh environments. This significantly reduces the equipment failure rate, decreases maintenance workload, and extends the equipment's lifespan, saving the company substantial production costs.

[0015] 3. The slag discharge speed adjustment device for this furnace slag cooler addresses the common problem in traditional technologies where slag easily accumulates and clogs at the slag outlet, affecting discharge efficiency and potentially causing production interruptions. This device features a servo-motor-driven stirring roller on one side of the slag discharge cylinder, directly above the slag outlet. During discharge, the stirring roller continuously agitates the slag within the cylinder, maintaining its fluidity and effectively preventing slag accumulation and blockage at the outlet. Simultaneously, the optimized design of the discharge and slag inlets, along with the precise adjustment of the discharge channel by the adjustable baffles, ensures smooth slag discharge from the cylinder. Compared to traditional technologies, this device significantly improves slag discharge efficiency, guarantees the normal operation of the furnace slag cooler, enhances the overall production efficiency, and generates greater economic benefits for the enterprise.

[0021] Please see Figure 1-3 A slag discharge speed adjustment device for a furnace slag cooler includes a slag discharge cylinder 1. An adjustment cylinder 2 is fixedly connected to the outer wall of the slag discharge cylinder 1 near its bottom. A rotating disk 3 is movably connected to the bottom of the inner wall of the adjustment cylinder 2. The top of the rotating disk 3 has six oblique adjustment grooves 4 arranged in a ring at equal intervals. An adjustment block 5 is inserted into one end of the inner wall of the oblique adjustment groove 4. The output end of the adjustment block 5 is located on the upper surface of the rotating disk 3. A limit slide 6 is opened at the bottom of the slag discharge cylinder 1. The top output end of the adjustment block 5 is slidably connected to the top of the inner wall of the limit slide 6. This structural design allows the adjustment block 5 to move linearly with the rotation of the rotating disk 3 under the constraint of the limit slide 6, thereby changing the effective cross-sectional area of ​​the slag discharge channel and realizing the adjustment of the slag discharge speed.

[0022] Furthermore, a gear ring 7 is fitted onto the outer wall of the rotating disk 3, and a bracket 8 is fixedly connected to one side of the outer wall of the slag discharge cylinder 1. A forward and reverse motor 9 is fixedly connected to the top side of the bracket 8. The bottom rotating shaft of the forward and reverse motor 9 extends to the bottom of the bracket 8. A gear 10 is fixedly connected to the bottom rotating shaft of the forward and reverse motor 9. The gear 10 and the gear ring 7 are meshed. The forward and reverse motor 9 can drive the rotating disk 3 to rotate through the meshing transmission of the gear 10 and the gear ring 7, thereby driving the adjusting block 5 to move within the limiting slide 6, providing power support for the adjustment of the slag discharge speed.

[0023] Furthermore, the bottom of the regulating cylinder 2 is provided with a slag discharge port 11, and the top of the slag discharge port 11 extends to the top of the rotating disk 3. The setting of the slag discharge port 11 allows the slag after regulation to be discharged smoothly from the bottom of the regulating cylinder 2. Its top extends to the top of the rotating disk 3, ensuring the smoothness of the slag discharge process and preventing the slag from accumulating in the regulating cylinder 2.

[0024] Furthermore, a slag discharge port 12 is provided at the bottom of the slag discharge cylinder 1 near the limiting slide 6. The slag discharge port 12 is parallel to the slag discharge port 11. The design of the slag discharge port 12 and the slag discharge port 11 being parallel to each other ensures that the slag can smoothly enter the regulating cylinder 2 from the bottom of the slag discharge cylinder 1 and be discharged through the slag discharge port 11, thus ensuring the continuity and smoothness of the slag discharge path.

[0025] Furthermore, a servo motor 13 is fixedly connected to the outer wall of one side of the slag discharge cylinder 1. The rotating shaft of the servo motor 13 extends to one side of the inner wall of the slag discharge cylinder 1. A stirring roller 14 is fixedly connected to the rotating shaft of the servo motor 13. The stirring roller 14 is movably connected to one end of the inner wall of the slag discharge cylinder 1 on the side away from the servo motor 13. The servo motor 13 drives the stirring roller 14 to rotate. The stirring roller 14 can stir the slag in the slag discharge cylinder 1, prevent the slag from accumulating and blocking at the slag outlet 12, and ensure the continuity and stability of the slag discharge process.

[0026] Furthermore, the stirring roller 14 is located directly above the slag discharge port 12, which can directly stir the slag that is about to enter the slag discharge port 12, more effectively preventing the slag from clogging the slag discharge port 12 and ensuring smooth slag discharge.

[0027] Furthermore, a fixing ring 15 is welded to the top of the slag discharge cylinder 1. The outer wall of the fixing ring 15 is provided with four mounting heads 16 distributed in a ring at equal intervals. The setting of the fixing ring 15 and the mounting heads 16 makes it easy to install and fix the entire slag discharge speed adjustment device on the furnace slag cooler, ensuring the stability and reliability of the device, and also facilitating the disassembly and maintenance of the device.

[0045] Working Principle: The device mainly consists of a slag discharge cylinder 1, an adjusting cylinder 2, and a rotating disk 3. The slag discharge cylinder 1 is connected to the adjusting cylinder 2 near its bottom outer wall. The rotating disk 3 inside the adjusting cylinder 2 is the key adjusting component. Its top has six equally spaced, annularly distributed inclined adjusting grooves 4. Adjusting blocks 5 are inserted into the inclined adjusting grooves 4, and the top output end of the adjusting blocks 5 is slidably connected to the top of the inner wall of the bottom limiting slide 6 of the slag discharge cylinder 1. When the slag discharge speed needs to be adjusted, the forward and reverse motor 9 starts, and its bottom rotating shaft drives the gear 10 to rotate. Since the gear 10 meshes with the gear ring 7 sleeved on the outer wall of the rotating disk 3, the rotation of the gear 10 drives the rotating disk 3 to rotate. During the rotation of the rotating disk 3, the inclined adjusting grooves 4 rotate accordingly, thereby causing the adjusting blocks 5 to perform linear reciprocating motion within the limiting slide 6. The change in the position of the adjusting blocks 5 within the inclined adjusting grooves 4 alters the effective cross-sectional area of ​​the slag discharge channel. When the adjusting block 5 moves towards the slag discharge port, the cross-sectional area of ​​the slag discharge channel decreases, and the slag discharge speed slows down; conversely, when the adjusting block 5 moves away from the slag discharge port, the cross-sectional area of ​​the slag discharge channel increases, and the slag discharge speed speeds up. During the slag discharge process, the servo motor 13 starts, and its rotating shaft drives the stirring roller 14 to rotate. The stirring roller 14 is located directly above the slag discharge port 12, which can stir the slag in the slag discharge cylinder 1, prevent the slag from accumulating and blocking at the slag discharge port 12, and ensure smooth slag discharge. The fixing ring 15 at the top of the slag discharge cylinder 1 and the four mounting heads 16 distributed in a ring at equal intervals facilitate the installation and fixation of the entire device on the furnace slag cooler. The slag discharge port 11 at the bottom of the adjusting cylinder 2 is parallel to the slag discharge port 12 at the bottom of the slag discharge cylinder 1. After the slag is discharged from the slag discharge port 12, it is discharged from the device through the slag discharge port 11.
