Description
Gas sealing automation device and system for coke oven doors
[0001] The present embodiments relate to an automated gas sealing device and system for a coke oven door that enables the automation of the sealing operation to prevent gas leakage of the coke oven door.
[0002] A coke oven is a device that heats coal to a high temperature to remove impurities and produce high-quality red-hot coke.
[0003] Generally, a coke oven consists of multiple carbonization chambers, and fuel coal is supplied to each chamber through the upper charging port.
[0004] In this process, coal is carbonized at high temperatures for a certain period of time and converted into coke.
[0005] The coke, after carbonization is complete, is discharged through the door of the carbonization room, loaded onto a digester, and transported to the process location.
[0006] During the coke manufacturing process, gaseous impurities such as coke oven gas (COG) are generated inside the carbonization chamber.
[0007] These gases must be confined within the carbonization chamber and not leak to the outside; however, due to the nature of the coke oven, a high-temperature and high-pressure environment persists, so there is a possibility of gas leakage occurring at the upper charging port, extrusion side door, coke side door, etc.
[0008] Such leaks occur more frequently, especially when a large amount of foreign matter (e.g., tar and carbon) adheres to the surface and frame of the door, impairing airtightness.
[0009] Such gas leaks cause various serious problems.
[0010] First, if high-temperature gas leaks outside the facility, it can cause damage and deformation to surrounding equipment.
[0011] Second, the emission of toxic gases not only reduces the safety of the working environment but also intensifies air pollution, exacerbating environmental problems.
[0012] This makes it more difficult to manage air quality and comply with environmental regulations at the factory, and can have an adverse effect on the health of local residents.
[0013] Third, worker safety is also a significant issue. Leaked gas poses serious risks to workers, such as burns, gas poisoning, falls, and entrapment, which are highly likely to lead to industrial accidents.
[0014] Currently, workers are using service carts to travel directly to the gas leak site and are performing sealing work.
[0015] However, this work is extremely dangerous due to risk factors such as high temperatures, toxic gases, and limited workspaces, and is identified as one of the major causes threatening worker safety.
[0016] Therefore, there is a need for technological development regarding devices and systems capable of automatically sealing gas leakage points in coke oven doors.
[0017] These embodiments enable the gas leak prevention operation of the coke oven door to be performed through the robot module, thereby fundamentally preventing the possibility of accidents occurring to workers due to gas leaks and significantly improving the speed and efficiency of the coke oven door sealing operation, and can provide an automated gas sealing device and system for a coke oven door.
[0018] In one aspect, embodiments described herein include: a horizontal rail module comprising a plurality of rail support members spaced apart at a position corresponding to a cork-of-door, a vertical rail member connected to the rail support members, and a horizontal rail member connected to the bottom surface of the vertical rail member; a saddle member comprising a driving module member configured to move along the horizontal rail module member; a vertical rail module member connected to the saddle member, positionally variable in the longitudinal direction of the horizontal rail module member, and spaced apart from the saddle member to form a workspace that expands in the vertical direction; a lifting member configured to correspond to the workspace and configured to have a robot module member, and which moves in the vertical direction along the vertical rail module member by means of a driving unit; and a control unit configured to control the movement of the saddle member and the lifting member so that the work position by the robot module member can be adjusted externally and communicates with an external control center server; wherein the robot module member comprises a body member installed in the lifting member; and a robot arm member connected to the body member in a manner that allows for angle change. An automated gas sealing device for a coke oven door can be provided, characterized by comprising: a sensor unit provided in the robot arm portion and detecting a gas leak portion of the coke oven door; and a nozzle portion formed at the end of the robot arm portion and discharging and applying a sealing material supplied from a sealing material supply portion to the gas leak portion of the coke oven door.
[0019] Additionally, a gas sealing automation system for a coke oven door can be provided, characterized by comprising: a control center server that monitors the gas leak situation of the coke oven door and generates a control signal including location information regarding the location where gas leaks from the coke oven door; and a gas sealing automation device for a coke oven door that receives the control signal from the control center server, moves to the coke oven door location corresponding to the location information, and seals the gas leak area of the coke oven door.
[0020] According to the embodiments, by enabling the gas leak prevention operation of the coke oven door to be performed through the robot module, it is possible to provide an automated gas sealing device and system for a coke oven door that can fundamentally prevent the possibility of accidents occurring to workers due to gas leaks.
[0021] In addition, it is possible to provide a gas sealing automation device and system for a coke oven door that can dramatically improve the sealing speed and work efficiency of the coke oven door.

[0036] A coke oven is a device that heats coal to a high temperature to remove impurities and produce high-quality red-hot coke.
[0037]
[0038] Generally, a coke oven consists of multiple carbonization chambers, and fuel coal is supplied to each chamber through the upper charging port.
[0039] In this process, coal is carbonized at high temperatures for a certain period of time and converted into coke.
[0040] The coke, after carbonization is complete, is discharged through the door of the carbonization room, loaded onto a digester, and transported to the process location.
[0041] During the coke manufacturing process, gaseous impurities such as coke oven gas (COG) are generated inside the carbonization chamber.
[0042] These gases must be confined within the carbonization chamber and not leak to the outside; however, due to the nature of the coke oven, a high-temperature and high-pressure environment persists, so there is a possibility of gas leakage occurring at the upper charging port, extrusion side door, coke side door, etc.

[0045] The gas sealing automation device for a coke oven door according to the present embodiment includes a lifting unit (400) comprising a horizontal rail module unit (100), a saddle unit (200), a vertical rail module unit (300), and a robot module unit (410), and a control unit (500).
[0046] The horizontal rail module (100) includes a plurality of rail support sections (110), a vertical rail section (120), and a horizontal rail section (130).

[0052] That is, the vertical rail section (120) can be connected to the vertical rail support section (113) included in the rail support section (110).
[0053] The horizontal rail section (130) is connected to the bottom surface of the vertical rail section (120).
[0054] When viewed from the side, the interconnected horizontal rail section (130) and vertical rail section (120) can have an overall 'T' shape.
[0055] Next, the saddle section (200) includes a driving module section (210) configured to move along the horizontal rail module section (100).
[0056] The driving module (210) may include a pair of first guide wheels (211) that travel along both sides of the vertical rail section (120); a pair of second guide wheels (213) that travel along both upper surfaces of the horizontal rail section (130); a driving wheel (215) that is positioned opposite to the lower part of the second guide wheel (213), is in close contact with the lower surface of the horizontal rail section (130), and is driven by rotation by a driving unit; and a tilting arm (219) that supports the driving wheel (215) rotatably, has one side connected to the saddle section (200) by a hinge (H), and has the other side elastically supported upward by an elastic structure (217).
[0057] The driving module (210) includes a pair of first guide wheels (211), a pair of second guide wheels (213), a driving wheel (215), and a tilting arm (219).

[0070] Here, the angle variable structure between the first saddle part (200a) and the second saddle part (200b) can be applied as a structure that rotates within a predetermined interval range around the hinge axis (H1), for example.
[0071] More specifically, the saddle section (200) is configured such that the first saddle body (212a) of the first driving module section (210a) and the second saddle body (212b) of the second driving module section (210b) are configured to move along the horizontal rail module section (100) rotate within a predetermined range around the hinge axis (H1).
[0072] Accordingly, the saddle section (200) is configured such that the angle between the first saddle body (212a) and the second saddle body (212b) is variable around the hinge axis (H1) in response to the bending of the horizontal rail module section (100). Therefore, even if the horizontal rail module section (100) is exposed to high temperatures and bending occurs, the angle between the first saddle body (212a) and the second saddle body (212b) can be flexibly changed, thereby preventing transfer failure.
