Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smelting furnaces, in particular to an emergency opening and closing device for a runner of a smelting furnace. Background Art
[0002] A smelting furnace refers to a device that melts metal ingots and some waste metals and adds necessary alloy components, and melts them into the required alloys through operations such as slag skimming and refining. During the casting operation in the integrated workshop, high-temperature liquid enters the casting machine through the runner of the smelting furnace for production. When the liquid level of the high-temperature liquid in the runner of the smelting furnace is too high or the flow rate of the furnace eye of the smelting furnace is too large and uncontrollable, affecting the normal production of the casting machine, the overflow of the high-temperature liquid will pose a great safety hazard to the workshop and the workshop staff. Content of the Utility Model
[0003] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to propose an emergency opening and closing device that ensures the safety of casting operations and workshop work and avoids great safety hazards.
[0004] To achieve this purpose, the utility model adopts the following technical solutions:
[0005] An emergency opening and closing device for a runner of a smelting furnace provided by the utility model includes a runner and an aggregate box located below the runner. An installation plate adapted to the top of the runner is arranged on the aggregate box through a support rod. A motor is arranged on the installation plate. Limit blocks are arranged on both sides of the runner. An emergency opening and closing structure is slidably connected between the two groups of limit blocks for opening and closing the runner. A discharge port is arranged at the bottom of the runner. A sealing baffle is arranged at the bottom of the discharge port. A pressing device is arranged on one side of the bottom of the runner away from the support rod for pressing the sealing baffle to keep the discharge port sealed. A sensor is arranged on the inner wall of the runner.
[0006] Preferably, the emergency opening and closing structure of the utility model includes a rotating shaft fixedly connected to the driving end of the motor. A connecting end is arranged on the rotating shaft. Truncated blocks slidably connected to the limit blocks are arranged on both sides of the connecting end. Through grooves are arranged between the two groups of truncated blocks and the limit blocks. When the limit blocks are in the liquid flow direction, the limit blocks form a blocking structure.
[0007] Preferably, one surface of the truncated block is arc-shaped and fits the inner wall of the runner, and the other surface is planar and connected to the connecting end.
[0008] Preferably, the sealing baffle of the utility model includes a sealing plate arranged at the bottom of the discharge port. The sealing plate is rotatably connected to the runner. A biting plate that closely fits the inner wall of the discharge port is arranged on the sealing plate.
[0009] The preferred technical solution of the present utility model is that the pressing device includes a fixed seat arranged on one side of the bottom of the flow channel. A pressing plate is slidably connected to the inner wall of the chute of the fixed seat. A connecting rod is arranged on the side of the pressing plate away from the sealing plate. A spring is connected between the pressing plate and the inner wall of the chute, and the spring is sleeved outside the connecting rod.
[0010] The preferred technical solution of the present utility model is that the pressing plate fits against one end of the sealing plate away from the rotating end.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] When the liquid level in the flow channel is too high, the sensor transmits a signal to the computer control terminal, and the computer control terminal controls the motor to work, so that the rotating shaft drives the connecting end to rotate. The connecting end drives the two cut-off blocks on both sides to rotate to be consistent with the liquid flow direction in the flow channel. At this time, both ends of the through groove are in contact with the two limit blocks on both sides, which is perpendicular to the liquid flow direction in the flow channel, so that the cut-off blocks can block the liquid in the flow channel, and the high-temperature liquid flows out from the discharge port at the bottom of the flow channel, avoiding overflow due to too high liquid level in the flow channel, affecting the workshop operation and the safety of the staff. At the same time, the high-temperature liquid is collected for subsequent operation use. When the through groove rotates to the position where it is connected to the liquid in the flow channel, the liquid can flow through;
[0013] The driving structure drives the sealing plate to rotate downward. One end of the sealing plate presses the pressing plate, so that the pressing plate presses the spring and slides along the inner wall of the chute. When the liquid in the flow channel is discharged completely, the driving structure drives the sealing plate to rotate upward. The sealing plate presses the pressing plate to move upward, so that the engaging plate engages at the discharge port. Under the action of the spring, the pressing plate is driven to move towards the sealing plate, so that the pressing plate presses against the bottom of the sealing plate to improve the sealing performance of the engaging plate to the discharge port and ensure the operation safety.

[0019] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific implementation manners.
[0020] An emergency opening and closing device for a runner of a smelting furnace includes a runner 1 and an aggregate bin 2 located below the runner 1. An installation plate 22 adapted to the top of the runner 1 is provided on the aggregate bin 2 through a support rod 21. A motor 23 is provided on the installation plate 22. Limit stops 3 are arranged on both sides of the runner 1. An emergency opening and closing structure 4 is slidably connected between the two groups of limit stops 3 for opening and closing the runner 1. A discharge port 11 is provided at the bottom of the runner 1. A sealing baffle 5 is provided at the bottom of the discharge port 11. A pressing device 6 is provided on one side of the bottom of the runner 1 away from the support rod 21 for pressing the sealing baffle 5 to keep the discharge port 11 sealed. The pressing device 6 is rotatably connected to the bottom of the runner 1. A driving structure is connected to the rotating section of the pressing device 6. A sensor is arranged on the inner wall of the runner 1. The sensor, the driving structure and the computer control terminal are in telecommunication connection.
[0021] When the liquid level of the high-temperature liquid in the runner 1 is relatively high, the sensor on the inner wall of the runner 1 transmits a signal to the computer control terminal. The computer control terminal issues a warning. The computer control terminal is in telecommunication connection with the motor 23 to control the operation of the motor 23. The motor 23 controls the rotation of the emergency opening and closing structure 4 to cut off the high-temperature liquid in the runner 1, so that the high-temperature liquid cannot pass through the latter half of the runner 1. At the same time, the computer control terminal controls the driving structure to drive the pressing device 6 to rotate, opening the discharge port 11 at the bottom of the runner 1, so that the high-temperature liquid inside the runner 1 is transferred to the aggregate bin 2 at the bottom for subsequent reuse in casting, avoiding waste of casting liquid. The emergency opening and closing structure 4 can timely block the high-temperature liquid inside the runner 1, avoiding overflow of the high-temperature liquid due to too high a liquid level in the runner 1, causing damage to workshop staff and equipment, and ensuring the safety of workshop staff and casting operations.
[0022] As a possible implementation of this solution, preferably, the emergency opening and closing structure 4 includes a rotating shaft 41 fixedly connected to the driving end of the motor 23. A connecting end 42 is provided on the rotating shaft 41. Truncation blocks 43 slidably connected to the limit blocks 3 are provided on both sides of the connecting end 42. A through groove 44 is provided between the two groups of truncation blocks 43 and the limit blocks 3. When the limit block 3 is in the liquid flow direction, the limit block 3 forms a blocking structure. One side of the truncation block 43 is in an arc shape that fits the inner wall of the flow channel 1, and the other side is in a planar shape connected to the connecting end 42.
[0023] When the liquid level in the flow channel 1 is too high, the sensor transmits a signal to the computer control terminal. The computer control terminal controls the motor 23 to work, causing the rotating shaft 41 to drive the connecting end 42 to rotate. The connecting end 42 drives the truncation blocks 43 on both sides to rotate to be in the same direction as the liquid flow in the flow channel 1. At this time, both ends of the through groove 44 are in contact with the limit blocks 3 on both sides, so that the truncation blocks 43 block the liquid in the flow channel 1, and the high-temperature liquid flows out from the discharge port 11 at the bottom of the flow channel 1, preventing the liquid in the flow channel 1 from overflowing due to the too-high liquid level, which may affect the workshop operation and the safety of the staff. At the same time, the high-temperature liquid is collected for subsequent operation use.
[0024] As a possible implementation of this solution, preferably, the sealing baffle 5 includes a sealing plate 51 provided at the bottom of the discharge port 11. The sealing plate 51 is rotatably connected to the flow channel 1. A clamping plate 52 that fits tightly with the inner wall of the discharge port 11 is provided on the sealing plate 51. The peripheral ends of the clamping plate 52 are in an arc shape adapted to the discharge port 11. When the liquid level in the flow channel 1 is too high, the sensor transmits a signal to the computer control terminal. The computer control terminal controls the driving structure to work. The driving structure drives the sealing plate 51 to squeeze the pressing device 6 and rotate downward. The sealing plate 51 drives the clamping plate 52 to move downward, allowing the liquid in the flow channel 1 to be discharged into the aggregate box 2 through the discharge port 11, collecting the blocked high-temperature liquid for subsequent use in casting operations.
[0025] As a possible implementation of this solution, preferably, the pressing device 6 includes a fixed seat 61 disposed on one side of the bottom of the flow channel 1. A pressing plate 62 is slidably connected to the inner wall of the chute 63 of the fixed seat 61. A connecting rod 64 is disposed on the side of the pressing plate 62 away from the sealing plate 51. A spring 65 is connected between the pressing plate 62 and the inner wall of the chute 63. The spring 65 is sleeved outside the connecting rod 64. The pressing plate 62 is attached to one end of the sealing plate 51 away from the rotating end. The driving structure drives the sealing plate 51 to rotate downward. One end of the sealing plate 51 presses the pressing plate 62, causing the pressing plate 62 to press the spring 65 and slide along the inner wall of the chute 63. When the liquid in the flow channel 1 is completely discharged, the driving structure drives the sealing plate 51 to rotate upward. The sealing plate 51 presses the pressing plate 62 to move upward, causing the clamping plate 52 to be clamped at the discharge port 11. Under the action of the spring 65, the pressing plate 62 is driven to move toward the sealing plate 51, so that the pressing plate 62 is pressed against the bottom of the sealing plate 51 to improve the sealing performance of the clamping plate 52 to the discharge port 11 and ensure the operation safety.
