Description

Technical Field

[0001] This utility model relates to the field of smelting equipment technology, specifically a splash-proof sealing device for the feed port of a smelting furnace. Background Technology

[0002] In modern metallurgical industry, the smelting furnace, as a core piece of equipment, undertakes the important task of transforming various ores and metal raw materials into desired metal products through high-temperature smelting. The feed inlet is the key channel for materials to enter the smelting furnace, and its performance has a crucial impact on the smooth progress of the smelting process, production efficiency, and production safety.

[0003] Currently, there are a series of problems that urgently need to be solved in the actual smelting production process. On the one hand, because the inside of the smelting furnace is a high-temperature, high-pressure environment accompanied by violent chemical reactions, when materials enter the furnace through the feed port, the high-temperature molten metal, slag, and high-pressure gas inside the furnace are prone to splashing. This splashing not only causes serious damage to equipment around the feed port, such as conveying pipelines, sensors, and control devices, increasing equipment maintenance costs and downtime, and affecting production efficiency, but also poses a direct threat to the life safety of on-site operators. Once splashed material hits a person, it is very likely to cause serious burns, crush injuries, and other safety accidents.

[0004] On the other hand, poor sealing performance of the feed port is also a prominent problem. Poor sealing leads to a significant loss of high-temperature heat from the furnace, which not only increases energy consumption and production costs, but also raises the ambient temperature, affecting the comfort and health of operators. Simultaneously, harmful gases generated inside the furnace, such as sulfur dioxide and carbon monoxide, may leak into the atmosphere through the poorly sealed feed port, polluting the surrounding environment, failing to meet environmental protection requirements, and potentially causing safety hazards such as explosions and poisoning accidents.

[0005] Furthermore, existing splash-proof and sealing measures are often complex in structure, inconvenient to operate, and require considerable manual intervention. This not only increases labor costs but also makes them susceptible to poor splash-proof and sealing performance due to human error. Moreover, these measures are prone to damage and aging under long-term high-temperature, corrosive, and other harsh working conditions, leading to performance degradation and an inability to function effectively and continuously. Utility Model Content

[0006] This utility model provides a splash-proof sealing device for the feed port of a smelting furnace, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A splash-proof sealing device for the feed port of a smelting furnace comprises a sealing plate, a feed pipe, an elastic moving mechanism, a material blocking mechanism, and a traction drive assembly.

[0008] A feed pipe is installed through and fixed on the sealing plate, through which the material enters the smelting furnace. A sealing ring made of high-temperature resistant rubber is fixed on the back side of the sealing plate. When the sealing plate is placed on the feed inlet of the smelting furnace, the sealing ring can effectively seal the feed inlet, preventing heat loss and leakage of harmful gases from the furnace.

[0009] Elastic moving mechanisms are located on both sides of the sealing plate. Each elastic moving mechanism includes a side seat, which is fixedly connected to the sealing plate via a side bracket. A guide rod is threaded through the side seat and slidably connected to it. An auxiliary spring is sleeved on the outside of the guide rod. One end of the auxiliary spring is fixedly connected to the side seat, and the other end is fixedly connected to the smelting furnace via an external equipment bracket. Furthermore, a magnetic seat is embedded in the back side of the side seat. The back side of the side seat is flat, and the area of ​​the smelting furnace near the side seat is designed as a planar structure parallel to the back side of the side seat. When the sealing plate covers the smelting furnace inlet, the side seat contacts the smelting furnace, and the magnetic seat enhances the attraction between them, further improving the stability of the device.

[0010] The feed tube is connected to a material blocking mechanism, which includes a material blocking plate disposed inside the feed tube. The material blocking plate is a circular plate with an outer diameter smaller than the inner diameter of the feed tube. A rotating rod is passed through and fixedly connected to the material blocking plate, and the rotating rod is used to drive the material blocking plate to rotate.

[0011] The traction drive assembly drives the rotating rod. It includes a turntable, with the rotating rod passing through the feed pipe and fixedly connected coaxially to the turntable. A rotating seat is rotatably connected to the off-center position of the turntable, and a fixed seat is fixedly mounted on the sealing plate. A hydraulic telescopic rod is rotatably connected to the fixed seat, and the telescopic end of the hydraulic telescopic rod is fixedly connected to the rotating seat. By controlling the extension and retraction of the hydraulic telescopic rod, the turntable can be rotated, which in turn drives the material blocking plate to rotate, thus opening and closing the feed pipe.

[0012] The magnetic base is made of electromagnet. When the side base comes into contact with the smelting furnace, the magnetic base is energized to achieve a firm adsorption. After the material is fed in, the electromagnet is de-energized. At this time, since the material is conveyed, the overall weight of the device is reduced. When the magnetic attraction force is lost, the auxiliary spring drives the entire device to reset.

[0013] The inner wall of the feed pipe is coated with an anti-stick coating to prevent materials from sticking to the inner wall of the feed pipe and ensure that the materials pass through smoothly.

[0014] This utility model has the following advantages: By setting a sealing plate and a feed pipe, this utility model effectively avoids material splashing caused by direct impact on the feed port, effectively protecting the safety of surrounding equipment and personnel. During the sealing process, the high-temperature resistant rubber sealing ring on the back side of the sealing plate fits tightly with the feed port of the smelting furnace, greatly reducing heat loss and harmful gas leakage, reducing energy consumption and environmental pollution. The elastic moving mechanism not only enables the sealing plate to automatically adjust its position according to the weight of the material to achieve sealing, but also the magnetic seat on the back side of the side seat matches the corresponding planar structure of the smelting furnace, enhancing the connection stability between the device and the smelting furnace.

[0022] Please see Figure 1-4A splash-proof sealing device for the feed port of a smelting furnace includes a sealing plate 1, a feed pipe 2 that is passed through and fixed on the sealing plate 1, and elastic moving mechanisms on both sides of the sealing plate 1. The feed pipe 2 is connected to a material blocking mechanism. The material blocking mechanism includes a material blocking plate 10 disposed inside the feed pipe 2, a rotating rod 11 passing through and fixedly connected to the material blocking plate 10, and a traction drive assembly 7 for driving the rotating rod 11 is provided outside the feed pipe 2. The elastic moving mechanism includes a side seat 4 disposed on one side of the sealing plate 1, a side bracket 3 fixedly connected between the side seat 4 and the sealing plate 1, a guide rod 5 passing through the side seat 4, the guide rod 5 being slidably connected to the side seat 4, an auxiliary spring 6 being sleeved on the outside of the guide rod 5, one end of the auxiliary spring 6 being fixedly connected to the side seat 4, and the other end of the auxiliary spring 6 being fixedly connected to the smelting furnace through an external equipment bracket; The traction drive assembly 7 includes a turntable 14, a rotating rod 11 passing through the feed pipe 2 and being coaxially and fixedly connected to the turntable 14, a rotating seat 15 being rotatably connected to the off-center position of the turntable 14, a fixed seat 12 being fixedly provided on the sealing plate 1, a hydraulic telescopic rod 13 being rotatably connected to the fixed seat 12, and the telescopic end of the hydraulic telescopic rod 13 being fixedly connected to the rotating seat 15.

[0023] Furthermore, a sealing ring 8 is fixedly provided on the back side of the sealing plate 1.

[0024] Furthermore, the sealing ring 8 is made of high-temperature resistant rubber.

[0025] Furthermore, a magnetic seat 9 is embedded on the back side of the side seat 4, the back side of the side seat 4 is a plane, and the area of ​​the smelting furnace near the side seat 4 is set as a planar structure parallel to the back side of the side seat 4.

[0026] Furthermore, the magnetic base 9 is made of an electromagnet.

[0027] Furthermore, the material blocking plate 10 is a circular plate, and the outer diameter of the material blocking plate 10 is smaller than the inner diameter of the feed pipe 2.

[0028] Furthermore, the inner wall of the feed pipe 2 is provided with an anti-sticking coating.

[0029] In the implementation of this utility model, the material used for smelting is conveyed into the feed pipe 2 through a conveying device. At this time, the baffle plate 10 is in a state of blocking the internal channel of the feed pipe 2. When the material moves to the baffle plate 10, it is blocked, causing the material to accumulate in the feed pipe 2. This gradually increases the weight of the entire device, thereby increasing the tension of the side seat 4 on the auxiliary spring 6. The entire device slides downwards along the guide rod 5 until the sealing plate 1 covers the feed inlet of the smelting furnace. At this time, the side seat 4 also contacts the smelting furnace, increasing stability. The sealing ring 8 seals the smelting furnace. The feed inlet is sealed, and then the hydraulic telescopic rod 13 is controlled to extend, driving the turntable 14 to rotate, which in turn drives the material blocking plate 10 to rotate, so that the feed pipe 2 is unobstructed. The material accumulated in the feed pipe 2 enters the feed port of the smelting furnace along the feed pipe 2, and finally falls into the smelting furnace for smelting. When the side seat 4 contacts the smelting furnace, the magnetic seat 9 is energized to achieve firm adsorption. When the material is completely fed, the electromagnet is de-energized. At this time, since the material is completely conveyed, the overall weight of the device is reduced. When the magnetic attraction force is lost, the auxiliary spring 6 drives the entire device to reset.

[0030] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
