[0026] The utility model provides an emergency relief device for a metallurgical furnace, which has the following beneficial effects:

[0027] (1) The utility model provides an emergency relief device for a metallurgical furnace with an ingenious structural design. In an emergency, once an abnormal situation is detected, an alarm is immediately triggered and a relief program is started. The controller controls the relief sealing components and the auxiliary relief sealing components to work together to achieve rapid relief of molten metal liquid, thereby effectively shortening the emergency response time, reducing the risk of accidents, and protecting production safety and the safety of life and property of personnel.

[0028] The present invention features a simple and ingenious mechanical design for a metallurgical furnace emergency relief device. The device incorporates a power mechanism, a sensor, an alarm, and a controller to achieve automated monitoring and response. Upon detecting an abnormality in the metallurgical furnace equipment, an alarm is immediately triggered and the relief procedure is initiated. The controller controls a first telescopic mechanism to drive the transverse relief plate of the blocking assembly to move transversely within the plate cavity of the relief pipe, thereby connecting the second through-hole of the relief plate with the first through-hole and the relief hole of the relief pipe, forming a relief channel. However, due to the low temperature and poor fluidity of the molten metal in the relief hole, direct relief is insufficient. Consequently, the controller controls a second telescopic mechanism to drive the scraping assembly to extend downward from the first through-hole of the relief pipe. Once the mandrel reaches the bottom center of the first through-hole, the mandrel begins to perform a scraping action as the second telescopic mechanism continues to roll and slide upward along the guide rail via the support bracket. At this time, the plug scrapes the molten metal in the discharge hole toward one side of the bottom of the furnace body through the coordinated scraping of the first scraping part and the second scraping part. The plug then moves in the opposite direction and returns to the initial position. The high-temperature molten metal inside the furnace body flows out, realizing the rapid discharge of the molten metal liquid and improving the safety performance of the metallurgical furnace.

[0029] (2) In the metallurgical furnace emergency discharge device of the present invention, the synergistic effect of the first scraping part and the second scraping part of the scraping assembly is mainly reflected in their scraping and pushing of the molten metal liquid. Since the diameter of the second scraping part is larger than that of the first scraping part and matches the diameter of the second through hole, it can more effectively scrape and push the molten metal liquid in the discharge hole. The first scraping part is located above the second scraping part, and the two form a certain hierarchical structure. This design helps to form a better metal liquid flow guide during the scraping process, ensuring that the metal liquid can be smoothly and quickly pushed to the side of the bottom of the furnace body, thereby allowing the metal liquid with higher temperature inside the furnace body to flow out and achieve rapid discharge.

[0030] At the same time, the design of the elastic layer helps the plug to pass through the discharge hole more smoothly. When the plug contacts the molten metal or the internal structure of the furnace body, the elastic layer can act as a buffer, reducing the impact and wear on the discharge hole and the through hole, thereby extending the service life of the equipment.

[0031] (3) The metallurgical furnace emergency discharge device of the present invention has a blocking component designed with a horizontal discharge plate and a vertical sealing plate. The horizontal discharge plate matches the plate cavity inside the discharge pipe, and the vertical sealing plate plays a further sealing role, ensuring good sealing performance. Under normal working conditions, it can effectively prevent the leakage of molten metal liquid. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0043] See also Figures 1-8 , the utility model provides a technical solution:

[0044] First, if Figures 1-4As shown, the emergency relief device of a metallurgical furnace provided by the utility model includes two groups of vertically arranged support frames and a furnace body 1, and the two groups of support frames are arranged in pairs around the bottom of the furnace body 1. One group of support frames includes a first support frame 3 and a second support frame 4. A relief hole is also provided between the first support frame 3 and the second support frame 4 and at the bottom of the furnace body 1. A relief device is provided at the bottom outlet of the relief hole. The relief device includes a relief sealing component 2 and an auxiliary relief sealing component. The relief sealing component 2 and the auxiliary relief sealing component are arranged opposite to each other. The relief sealing component 2 includes a first telescopic mechanism 202 and a relief pipe 201. The relief pipe 201 is penetrated by a first through hole 2012 and is connected to the bottom of the relief hole. A plate cavity is horizontally opened inside the relief pipe 201. The first telescopic mechanism 202 is horizontally fixed to the upper part of the first support frame 3, and the telescopic end of the first telescopic mechanism 202 is fixed with a blocking component 203, the blocking assembly 203 includes a transverse discharge plate 2031 that matches the plate cavity, and a second through hole 2031 is provided on the transverse discharge plate 2031, and the transverse discharge plate 2031 can move along the transverse length direction of the plate cavity, and the auxiliary leakage sealing assembly includes a guide rail mechanism 8 and a second telescopic mechanism 701, the guide rail mechanism 8 is vertically installed on the second support frame 4, and the second telescopic mechanism 701 can be slidably installed laterally on the guide rail mechanism 8, and the telescopic end of the second telescopic mechanism 701 is provided with a vertically arranged top scraping assembly, and the top scraping assembly includes a top head 704, and the top head 704 can move up and down along the through direction of the discharge channel formed by the first through hole 2012, the second through hole 2031 and the discharge hole. The furnace body 1 is also provided with a power mechanism, a sensor, an alarm and a controller connected to the leakage sealing component 2 and the auxiliary leakage sealing component, and the operation is controlled by the controller.

[0045] This device has a simple and ingenious structural design, combining a power mechanism, sensors, alarms, and a controller to achieve automated monitoring and response. Once an abnormality in the metallurgical furnace equipment is detected, an alarm is immediately triggered and the discharge process is initiated. The controller controls the first telescopic mechanism 202 to drive the transverse discharge plate 2031 of the blocking assembly 203 to move transversely within the plate cavity of the discharge pipe 201, allowing the second through-hole 20311 of the transverse discharge plate 2031 to connect with the first through-hole 2012 of the discharge pipe 201, forming a discharge channel. However, due to the low temperature and poor fluidity of the molten metal in the discharge hole, direct discharge is not rapid enough. In this case, the controller further controls the second telescopic mechanism 701 to drive the top scraper assembly to extend downward from the first through-hole 2012 of the discharge pipe 201. Once the top scraper assembly's head 704 reaches the bottom center of the first through-hole 2012, the head 704 begins its scraping action as the second telescopic mechanism 701 rolls upward along the guide rail via the support bracket 9. The molten metal in the discharge hole pushes toward one side of the bottom of the furnace body 1, and the head 704 moves in the opposite direction and returns to the initial position. The high-temperature molten metal inside the furnace body 1 flows out, realizing the rapid discharge of the molten metal liquid and improving the safety performance of the metallurgical furnace.

[0046] A vertical mounting base 5 is provided on the upper left portion of the first support frame 3. The first telescopic mechanism 202 is a group of telescopic cylinders arranged in parallel. The two telescopic cylinders are fixedly mounted on the vertical mounting base 5. A support plate 6 is also provided below the mounting base. A third reinforcing plate 601 is fixedly connected between the support plate 6 and the first support frame 3, so that the telescopic cylinders can be firmly fixed, and can remain stable and reliable regardless of the telescopic action or the pressure.

[0047] like Figure 5-Figure 7 As shown, the sealing assembly 203 also includes a vertical sealing plate 2032. An elastic resistance member 2011 is provided at the bottom of the plate cavity. One end of the transverse discharge plate 2031 is vertically fixed to the middle position of one side of the vertical sealing plate 2032. The other end of the transverse discharge plate 2031 can contact the elastic resistance member 2011. The middle position of the other side of the vertical sealing plate 2032 is fixedly connected to the top of the telescopic rod of the two telescopic cylinders. Driven by the first telescopic mechanism 202, the transverse discharge plate 2031 can flexibly move within the plate cavity, realizing the function of quickly opening and closing the discharge hole. When the transverse discharge plate 2031 completely blocks the discharge pipe 201, its other end contacts the elastic resistance member 2011. This not only ensures the sealing of the discharge pipe 201, but also prevents the risk of leakage under high temperature and high pressure. During the discharge process, the elastic resistance member 2011 can play a certain buffering role, reducing the impact and wear on the discharge pipe 201 and extending its service life.

[0048] The discharge pipe 201 is a square structure. A V-shaped sealing ring is provided at the right side of the discharge pipe 201 and at the top outlet edge of the plate cavity. A V-shaped groove for the sealing ring that matches the V-shaped sealing ring is provided on the vertical sealing plate 2032. The combination of the vertical sealing plate 2032 and the V-shaped sealing ring further enhances the sealing performance of the discharge pipe 201. The V-shaped sealing ring and the elastic resistance piece 2011 are both made of refractory materials. In this structure, the sealing assembly 203 adopts the design of a horizontal discharge plate 2031 and a vertical sealing plate 2032. The horizontal discharge plate 2031 matches the plate cavity inside the discharge pipe 201, and the vertical sealing plate 2032 plays a further sealing role, ensuring good sealing performance. Under normal working conditions, the leakage of molten metal can be effectively prevented. The V-shaped sealing ring and the elastic resistance piece 2011 are both made of refractory materials. Refractory materials can maintain stable physical and chemical properties at high temperatures and will not lose the sealing effect or produce harmful substances due to high temperatures.

[0049] like Figure 2 、 Figure 4 、 Figure 8 As shown, the guide rail mechanism 8 is a rolling guide rail, and a support bracket 9 is connected to the slider connected to the screw rod of the rolling guide rail. The bottom two sides of the support bracket 9 are provided with slide grooves matching the guide rail, and can roll and slide relative to the guide rail. Limiting members are also provided on both sides of the support bracket 9 to prevent the support bracket from exceeding the predetermined range during movement. The second telescopic mechanism 701 is fixedly mounted on the top of the support bracket 9. In this structure, the rolling guide rail has a higher load capacity and a longer service life, which is particularly important for the emergency discharge device of the metallurgical furnace, because the device needs to work in harsh environments such as high temperature and high pressure, and has high requirements on the load capacity and durability of the equipment. And by controlling the rotation direction and rotation amount of the screw rod, the moving distance and position of the support bracket 9 can be accurately controlled, thereby realizing precise control of the up and down moving distance of the second telescopic mechanism 701.

[0050] like Figure 8 As shown, the top scraping assembly also includes a vertical support rod 703, a top head 704 fixed to the top of the vertical support rod 703 via a circular ring connector, and the bottom of the vertical support rod 703 is vertically fixedly connected to the telescopic rod of the second telescopic mechanism 701; an L-shaped reinforcement 702 is provided on the outside of the connection between the vertical support rod 703 and the second telescopic mechanism 701, and a first reinforcement plate 7022 is also provided between the long rod and the short rod of the L-shaped reinforcement 702, thereby enhancing the structural strength of the connection between the vertical support rod 703 and the second telescopic mechanism 701. A limiting ring 7021 is provided at the end of the long rod and the short rod of the L-shaped reinforcement 702. The setting of the limiting ring 7021 provides limiting protection between the long rod and the short rod of the L-shaped reinforcement 702, further improving the safety and reliability of the equipment.

[0051] The mandrel 704 comprises a conical column body 7044, with a first scraping portion 7041 disposed at its top and a second scraping portion 7043 disposed at its bottom. The first scraping portion 7041 and the second scraping portion 7043 form a circular ring structure with an arced exterior. The diameter of the second scraping portion 7043 is larger than that of the first scraping portion 7041 and matches the diameter of the second through-hole 20311. Second reinforcing plates 7042 are evenly spaced and fixed between the second scraping portion 7043 and the conical column body 7044. This design ensures uniform contact between the mandrel 704 and the hole wall during movement, reducing wear and improving scraping efficiency. Furthermore, the evenly spaced attachment of the second reinforcing plates 7042 increases the strength of the second scraping portion 7043, preventing deformation or damage during scraping and pushing. The mandrel 704 is made of a refractory material, and the outer layer of the second scraping portion 7043 is an elastic layer.

[0052] In the above structure, the first scraping portion 7041 and the second scraping portion 7043 of the scraping assembly work together to scrape and push the molten metal upward. Because the second scraping portion 7043 has a larger diameter than the first scraping portion 7041 and matches the diameter of the second through hole 20311, it can more effectively scrape and push the molten metal within the discharge hole. The first scraping portion 7041 is located above the second scraping portion 7043, and the two form a certain hierarchical structure. This design helps to form a better flow guide for the molten metal during the scraping process, ensuring that the molten metal can be smoothly and quickly pushed to the side of the bottom of the furnace body 1, thereby allowing the higher temperature molten metal inside the furnace body to flow out and achieve rapid discharge.

[0053] At the same time, the design of the elastic layer helps the head 704 to pass through the discharge hole more smoothly, and when the top scraper assembly contacts the metal solution or the furnace structure, the elastic layer can act as a buffer, reducing the impact and wear on the discharge hole and the through hole, thereby extending the service life of the equipment.

[0054] In addition, after the metal solution inside the furnace body is discharged, the controller again controls the second telescopic mechanism 701 to drive the scraping assembly to repeat the above-mentioned scraping action, scraping the metal solution on the inner wall of the discharge channel formed by the first through hole 2012, the second through hole 20311 and the discharge hole and pushing it to one side of the bottom of the furnace body 1, which can further clean the metal solution remaining on the inner wall of the discharge channel, ensure that the channel is unobstructed, provide better conditions for subsequent blocking and re-discharge work, and reduce the operational difficulties and efficiency reduction caused by channel blockage.

[0055] Working principle:

[0056] First, when the metallurgical furnace is in normal operation, the vent hole is tightly sealed by the sealing assembly 203. The sealing assembly includes a horizontal vent plate 2031 and a vertical sealing plate 2032. These, through the action of a first telescopic mechanism 202 (typically a set of telescopic cylinders), fit tightly against the plate cavity and outlet of the vent pipe 201, ensuring that no liquid metal or gas can leak out.

[0057] When a malfunction occurs in the metallurgical furnace, the alarm sounds. Upon receiving a signal from the sensor, the controller activates the power mechanism, driving the first telescopic mechanism 202. The telescopic cylinder's telescopic rod rapidly contracts, driving the transverse discharge plate 2031 backward. This allows the second through-hole 20311 of the discharge plate 2031 to connect with the first through-hole 2012 of the discharge pipe and the discharge hole, forming a discharge channel. However, due to the low temperature and poor fluidity of the molten metal in the discharge hole, direct discharge is insufficient. Therefore, the controller controls the second telescopic mechanism 701 to drive the scraping assembly to extend downward from the first through-hole 2012 of the discharge pipe 201. Once the ram 704 reaches the bottom center of the first through-hole 2012, the ram 704 begins its upward scraping action as the second telescopic mechanism 701 rolls and slides upward along the guide rail via the support bracket 9. At this time, the plug 704 is scraped upward by the cooperation of the first scraping part 7041 and the second scraping part 7043, and the molten metal in the discharge hole is pushed toward the side of the bottom of the furnace body 1. At the same time, the second telescopic mechanism 701 moves downward along the guide rail through the support bracket 9, driving the driving plug 4 to move downward. Then the telescopic rod of the second telescopic mechanism 701 contracts backward, thereby driving the plug 704 to move backward away from the discharge pipe 201 and return to its initial position, so that the high-temperature molten metal inside the discharge furnace body 1 quickly flows out, realizing the rapid discharge of the molten metal liquid, thereby improving the safety performance of the metallurgical furnace.

[0058] When the internal pressure of the metallurgical furnace returns to normal, the controller will start the power mechanism again, drive the telescopic mechanism 202 to move in the reverse direction, push the blocking component back to its original position, and block the discharge hole again.

[0059] In summary, the emergency relief device for a metallurgical furnace of the utility model has an ingenious structural design. In an emergency, once an abnormal situation is detected, an alarm is immediately triggered and a relief program is started. The controller controls the relief sealing components and the auxiliary relief sealing components to work together to ensure that the molten metal liquid is quickly and safely discharged, thereby significantly improving the overall safety performance of the metallurgical furnace.

[0060] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
