Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment maintenance technology, and more specifically, to a hot-repair furnace charging machine. Background Technology

[0002] The refractory lining of an electric arc furnace is worn down during smelting due to the scouring effect of high-temperature molten steel, temperature changes, and mechanical impact. It typically requires hot repairs every 250-300 heats, consuming 15-20 tons of refractory ramming material each time. Currently, the common practice is to use a crane to transport ladles into the furnace, relying on the high temperature to melt the ladles and allow the ramming material to spread out naturally.

[0003] However, this method has obvious drawbacks: the melting process of the ton bag is uncontrollable, causing the ramming material to pour out suddenly, making it impossible to achieve uniform or precise material distribution; the operation requires multiple hoisting operations, taking up to 2.5-3 hours, resulting in excessively long hot shutdown time of the electric furnace and low production efficiency; personnel need to work at close range in high temperatures, which is labor-intensive and risky, and the ton bags cannot be recycled, increasing costs. Utility Model Content

[0005] The embodiments of this utility model can be implemented as follows: This utility model provides a hot-melt furnace material feeding machine, comprising: The tank body has a feed inlet at the top and a discharge outlet at the bottom, and is used to contain ramming material.

[0010] In an optional embodiment, the axial direction of the drive shaft is collinear with or parallel to the central axis of the tank.

[0011] In an optional embodiment, the rotating flow channel includes a receiving funnel and a guide pipe.

[0014] In an optional embodiment, the tank body includes a cylindrical body and a conical body connected vertically, with the inlet located at the top of the cylindrical body and the outlet located at the bottom of the conical body.

[0015] The beneficial effects of the hot-repair furnace material feeding machine provided in this embodiment of the utility model include: 1. By setting up a fixed tank that combines storage and hoisting functions and a controllable discharge valve, it is possible to achieve precise control over the unloading process and the flow rate of tamping material, thereby completely overcoming the uncontrollable unloading problem caused by the melting of ton bags and laying the foundation for uniform material distribution.

[0016] 2. By driving the rotating flow channel through the drive and transmission devices, the tamping material flow can be guided to any position within a 360-degree range, thereby achieving uniform material distribution over a large area or precise material distribution to a specific area, significantly improving the repair quality.

By using large-capacity tanks for centralized material supply, the hoisting operations that originally required more than ten separate operations can be integrated into one operation, thereby greatly shortening the total time of hot repair operations, reducing the hot shutdown time of the electric arc furnace, and improving production efficiency.

Detailed Implementation

[0023] In related technologies, the common method for placing ton bags into the furnace during electric arc furnace heat repair is to use an overhead crane to directly hoist them into the furnace. This method suffers from problems such as uncontrollable material placement, low work efficiency, high labor intensity, and high cost of ramming material. Specifically, because the ton bags melt and break rapidly at high temperatures, the ramming material spills out in a concentrated manner, making uniform placement impossible. Furthermore, multiple hoisting operations are required, which not only prolongs the heat repair time but also forces operators to work at close range in high temperatures, posing safety risks. Additionally, the ton bags cannot be recovered.

[0024] To address the aforementioned problems, this invention provides a hot-melt furnace material distribution machine. It achieves precise control of the unloading flow rate through a fixed tank and a controllable discharge valve, and realizes 360-degree directional material distribution by driving a rotating flow channel. This improves issues such as poor material distribution uniformity, low operating efficiency, high labor intensity, and high consumption of tamping material. Through mechanized and remote operation, this invention significantly improves the quality and efficiency of hot-melt repair while reducing safety risks and production costs.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0031] The following describes in detail the overall structure, working principle, and technical effects of the hot-repair furnace material feeding machine provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1 The hot-repair furnace material distribution machine 100 provided by this utility model is applied to the hot repair operation of the bottom of electric arc furnace in the metallurgical industry. Specifically, it relates to a special material distribution equipment that can realize the uniform laying or fixed-point placement of refractory ramming material on the bottom of electric arc furnace.

[0033] The charging feeder 100 for this hot-melt furnace includes a tank body 10, a feeding valve 30, a rotating flow channel 20, a drive unit 40, and a transmission unit 50. The tank body 10 has a feed inlet 13 at its top and a discharge outlet 14 at its bottom. The tank body 10 is used to hold ramming material. The feeding valve 30 is located at the discharge outlet 14 and is used to control the discharge flow rate of the ramming material. The rotating flow channel 20 is located below the feeding valve 30 and is used to guide the ramming material to flow downwards at an angle. The drive unit 40 is mounted on the tank body 10. The two ends of the transmission unit 50 are connected to the drive unit 40 and the rotating flow channel 20, respectively, and are used to transmit the power of the drive unit 40 to the rotating flow channel 20, causing the rotating flow channel 20 to rotate relative to the tank body 10.

[0034] The feed inlet 13 is used to add refractory ramming material into the tank 10, and allows the ton bags containing the ramming material to be recycled after feeding, realizing the reuse of the ton bags. The discharge outlet 14 is used to discharge the ramming material from the bottom of the tank 10. The discharge flow rate of the ramming material is controlled by controlling the opening and closing degree of the discharge valve 30. The rotating flow channel 20 is used to receive the ramming material flowing out from the discharge valve 30, and rotates around the tank 10 under the transmission action of the drive device 40 and the transmission device 50, so as to evenly distribute the ramming material to the bottom area of ​​the electric arc furnace in a centrifugal throwing manner, or to achieve fixed-point feeding by positioning and stationary operation.

[0035] It should be noted that when the tank 10 is located outside the electric arc furnace, refractory ramming material is added into the tank 10. In this embodiment, the internal space of the tank 10 is approximately 18.5 m³. 3 The tank can hold approximately 23 tons of ramming material, meeting the ramming material capacity requirements for a single hot repair of the electric arc furnace. By using a large-capacity tank 10 for centralized material supply, the lifting operations that originally required multiple steps can be integrated into a single operation, significantly reducing the total time spent on hot repair, minimizing electric arc furnace downtime, and improving production efficiency. After adding ramming material to the tank 10 and recovering the ton bags, the tank 10 is hoisted, transported, and precisely placed into the predetermined position inside the electric arc furnace. Subsequently, the ramming material distribution operation can be carried out.

[0036] Specifically, the discharge valve 30 includes two opposing sector-shaped valve plates 31. The two sector-shaped valve plates 31 are respectively connected to the tank body 10 via a transmission mechanism. The hot-melt furnace material distributor 100 also includes a discharge drive component 32. The discharge drive component 32 is used to drive the sector-shaped valve plates 31 to rotate, thereby controlling the opening size between the two sector-shaped valve plates 31. By controlling the relative rotation angle of the two sector-shaped valve plates 31, the effective opening area of ​​the discharge port 14 can be precisely and continuously adjusted, thereby enabling control of the ramming material flow rate and ensuring that the ramming material can flow out uniformly at a constant or variable rate according to process requirements.

[0037] Understandably, when the two sector valve plates 31 rotate towards each other and move closer together, the discharge valve 30 is closed, and the ramming material is sealed inside the tank 10 and cannot be discharged from the outlet 14. When the two sector valve plates 31 rotate synchronously in opposite directions and move away from each other, a gradually increasing opening is formed between the two sector valve plates 31, and the ramming material flows out through this opening under the action of gravity, thus achieving precise control of the discharge flow rate.

[0038] Furthermore, in this embodiment, the feeding drive 32 consists of two drive cylinders. The two drive cylinders are mounted on the tank body 10. Each drive cylinder is connected to a sector valve plate 31 via a connecting rod 33, thereby pulling the sector valve plate 31 to rotate relative to the tank body 10. The piston rod ends of the two drive cylinders are hinged to the corresponding sector valve plate 31 via a connecting rod 33, so that the extension and retraction of the piston rod pulls the sector valve plate 31 to rotate around its axis of rotation relative to the tank body 10. By using two independent drive cylinders to control the two sector valve plates 31 respectively, it can be ensured that the force on both sides of the sector valve plates 31 is uniform, the movement is synchronized, and the response is rapid, thereby achieving high-precision and high-reliability adjustment of the opening size of the discharge port 14. Furthermore, the position of a single sector valve plate 31 can be fine-tuned when necessary, thereby compensating for possible mechanical errors or wear, ensuring that the two sector valve plates 31 can fit tightly when closed, achieving a reliable seal and preventing material leakage.

[0039] In this embodiment, the drive cylinder is a hydraulic cylinder. In other embodiments, the drive cylinder can be configured with other structures as needed, such as a pneumatic cylinder, an electric actuator, or a linear motor 41. This invention does not limit this.

[0040] Furthermore, the drive unit 40 includes a motor 41 and a reducer 42 connected to the output end of the motor 41. The output end of the reducer 42 is connected to the transmission unit 50. By adopting the combination of the motor 41 and the reducer 42, the reducer 42 can increase the output torque and reduce the speed, thereby providing a smooth, powerful, and controllable rotational force for the rotating flow channel 20, ensuring stable operation even under high loads. Specifically, the motor 41 and the reducer 42 are integrated and installed on a support on the top or side of the tank 10, which can make full use of the structural strength and space of the tank 10, facilitating overall hoisting and installation.

[0041] Please refer to Figure 1 and Figure 2 The transmission device 50 includes a drive shaft 51, a coupling 52, and a bearing housing 53. One end of the drive shaft 51 is connected to the output end of the drive device 40 via the coupling 52. Specifically, one end of the drive shaft 51 is connected to the output end of the reducer 42 via the coupling 52. The other end of the drive shaft 51 is fixedly connected to the rotating flow channel 20. The bearing housing 53 is fixedly installed inside the tank body 10 to support the drive shaft 51. Specifically, the bottom of the drive shaft 51 passes through the bottom of the tank body 10 and is fixedly connected to the rotating flow channel 20 by a nut. By setting a drive shaft 51 that passes through the tank body 10 and rigidly connecting one end to the output end of the reducer 42, the power of the drive device 40 can be transmitted to the rotating flow channel 20 located below the tank body 10, ensuring the reliability and synchronization of power transmission. By setting a bearing seat 53 inside the tank body 10 to support the drive shaft 51, the bending moment and radial runout of the drive shaft 51 caused by the cantilevered installation of the rotating flow channel 20 can be overcome, thereby ensuring that the drive shaft 51 can still rotate smoothly under heavy load and extend the service life of the equipment.

[0042] Specifically, the axial direction of the drive shaft 51 is collinear with or parallel to the central axis of the tank body 10. In this embodiment, by arranging the drive shaft 51 collinear with the central axis of the tank body 10, the rotating flow channel 20 can rotate around the central axis of the tank body 10, thereby ensuring the stability of the equipment's center of gravity during the material placement process, avoiding the additional torque generated by eccentric rotation that would cause the tank body 10 to sway, and ensuring the smoothness of the overhead crane lifting and material placement operations.

[0043] Furthermore, in this embodiment, the bottom of the drive shaft 51 extends beyond the tank body 10 through the discharge port 14. The shape of the sector valve plate 31 is adapted to the area where the drive shaft 51 passes through the discharge port 14. When the two sector valve plates 31 are brought together to the closed position, their inner edge contours can tightly fit or wrap around the outer periphery of the drive shaft 51, thereby achieving an effective seal of the discharge port 14.

[0044] In other embodiments, the drive shaft 51 can be arranged parallel to the central axis. Although there is a certain eccentricity, the rotational stability can still be maintained by the constraint of the bearing seat 53. This allows space to be reserved for the installation of other components under specific structural design requirements, thereby enhancing the functionality of the equipment.

[0045] Please continue to refer to Figure 1 The rotating flow channel 20 includes a receiving funnel 21 and a guide pipe 22. The upper opening of the receiving funnel 21 is located at the bottom of the discharge valve 30. The guide pipe 22 is connected to the lower opening of the receiving funnel 21. The extension direction of the guide pipe 22 is set at an angle to the axial direction of the drive shaft 51. By setting the receiving funnel 21 with a wide upper opening, it can be ensured that all the ramming material falling from the discharge valve 30 can be effectively captured, preventing the ramming material from splashing or spilling, and improving the utilization rate of the ramming material. Through the guiding effect of the angled structure of the guide pipe 22, the gravitational potential energy of the falling ramming material can be effectively converted into forward projectile kinetic energy, so that the ramming material falls to the bottom of the furnace with a gentler trajectory, forming a more uniform and flat auxiliary material layer, and avoiding the accumulation of ramming material.

[0046] In this embodiment, the drain pipe 22 is fixedly connected to the receiving funnel 21. The bottom of the drive shaft 51 is fixedly connected to the drain pipe 22 by a nut, so as to drive the rotating flow channel 20 to rotate around the axis of the drive shaft 51.

[0047] Furthermore, in other embodiments, the angle between the drainage tube 22 and the drive shaft 51 can be set to an adjustable structure. For example, the bottom of the drive shaft 51 can be fixedly connected to the receiving funnel 21 via a connector, so that the drive shaft 51 is located at the center of the receiving funnel 21, thereby causing the receiving funnel 21 and the drainage tube 22 to rotate as a whole around the axis of the drive shaft 51, rather than rotating eccentrically. The lower opening of the receiving funnel 21 is connected to the upper end of the drainage tube 22 via a hinge mechanism, and the relative angle between the drainage tube 22 and the drive shaft 51 is adjusted by one or more linear motors 41; or, the drainage tube 22 is composed of a section of flexible corrugated pipe, and the drainage direction is changed by adjusting its bending shape.

[0048] In this embodiment, the coupling 52 is a gear coupling 52. The gear coupling 52 transmits torque through the multi-tooth meshing of internal and external teeth, which can transmit very large torque, has a strong load-bearing capacity, and can meet the requirements of driving the heavy-duty rotating flow channel 20.

[0049] To facilitate the hoisting of the tank body 10, the hot-melt furnace charging machine 100 also includes a hoisting mechanism 60. The hoisting mechanism 60 includes multiple anchor chains 61 and lifting rings 62. One end of each anchor chain 61 is symmetrically arranged along the central axis of the tank body 10 at the top of the tank body 10. The other end of each anchor chain 61 is connected to a lifting ring 62. By using multiple anchor chains 61 symmetrically arranged along the central axis of the tank body 10, the force on each hoisting point can be evenly distributed during hoisting, thereby ensuring that the tank body 10 remains level and stable during transport, preventing the tank body 10 from overturning, swaying, or rotating due to a shift in the center of gravity, and ensuring operational safety.

[0050] Specifically, the tank 10 includes a cylindrical body 11 and a conical body 12 connected vertically. The inlet 13 is located at the top of the cylindrical body 11. The outlet 14 is located at the bottom of the conical body 12. By adopting a combined structure of a cylindrical body 11 at the top and a conical body 12 at the bottom, the cylindrical body 11 can provide the maximum volume to hold a large amount of ramming material, thus meeting the ramming material requirements for completing hot patching operations in one go and reducing the number of lifting operations. The conical body 12 at the bottom allows the ramming material to slide naturally towards the central outlet 14 under gravity, ensuring smooth and complete discharge of the ramming material from the tank 10 and effectively preventing ramming material residue in corners.

[0051] The working principle and process of the hot-repair furnace material placing machine 100 provided in this embodiment of the utility model are as follows: 1. Preparation and charging (outside the furnace stage): Before shutting down the electric arc furnace for hot repair, the hot repair furnace charging feeder 100 is placed in a safe area outside the furnace. Operators add bulk refractory ramming material (usually from recycled ton bags) into the tank 10 through the top feed inlet 13 until the required capacity is reached. After loading, the ton bags are recycled for reuse. The overhead crane holds the entire equipment via the lifting rings 62 of the hoisting mechanism 60.

[0052] 2. Lifting and positioning: The overhead crane smoothly lifts the entire hot-repair furnace material feeder 100, which is already filled with ramming material, and transports it above the furnace mouth of the electric arc furnace. Then, it is slowly lowered and precisely hoisted into the electric arc furnace, where it is suspended at the predetermined material feeding height in the furnace chamber.

[0053] 3. Power connection and start-up: The operator remotely connects the power supply to the drive unit 40 (motor 41 and reducer 42) and the hydraulic lines controlling the unloading drive component 32 (cylinder). Then, the equipment is started via remote control.

[0054] 4. Fabric handling: Material feeding control: The operator controls the feeding drive 32 via remote control, which drives the two sector valve plates 31 to rotate synchronously in opposite directions via the connecting rod 33, opening the feeding valve 30 to the required opening degree. The tamping material flows out evenly from the discharge port 14 under the action of gravity.

[0055] Rotary flow guide: The outflowing rammed material falls into the receiving funnel 21 of the rotating flow channel 20 directly below. At the same time, the drive device 40 drives the entire rotating flow channel 20 to rotate around the central axis of the tank body 10 through the transmission device 50.

[0056] Uniform spreading: The ramming material is continuously and uniformly spread obliquely within the rotating flow channel 20, guided by the diversion pipe 22, under the action of centrifugal force. The operator can coordinate to control the slow movement of the crane, so that the spread ramming material covers the entire furnace bottom area, forming a material layer of uniform thickness.

[0057] 5. Completion and hoisting: After all the ramming material in tank 10 has been spread, the operator remotely closes the discharge valve 30, stops the drive device 40, and disconnects the power source. Finally, the operator directs the overhead crane to lift the unloaded material placing machine out of the furnace, completing this hot repair operation.

[0058] The beneficial effects of the hot-fixing furnace material feeding machine 100 provided in this embodiment of the utility model include: 1. By setting up a fixed tank 10 that combines storage and hoisting functions and a controllable discharge valve 30, precise control of the unloading process and the flow rate of tamping material can be achieved, thereby completely overcoming the uncontrollable unloading problem caused by the melting of ton bags and laying the foundation for uniform material distribution.

[0059] 2. By driving the rotating flow channel 20 to rotate through the drive device 40 and the transmission device 50, the tamping material flow can be guided to any position within a 360-degree range, thereby achieving uniform material distribution over a large area or precise material distribution to a specific area, significantly improving the repair quality.

[0060] 3. By using a large-capacity tank 10 for centralized material supply, the hoisting operation that originally required more than ten separate operations can be integrated into one operation, thereby greatly shortening the total time of hot repair operations, reducing the hot shutdown time of the electric arc furnace, and improving production efficiency.

[0061] 4. Through the overall mechanized and remote operation mode, operators can be kept away from the high-temperature heat radiation area of ​​the electric arc furnace, thereby significantly reducing their labor intensity and safety risks.

[0062] 5. By centrally feeding and recycling the ton bags outside the tank 10, it is possible to avoid them burning inside the furnace, thereby enabling the reuse of the ton bags.

[0063] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
