[0027] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0028] One embodiment of this application is a coal loading car, such as... Figure 1 As shown, it includes a vehicle body 1, a coal-carrying bottom plate 2, a rear baffle 4, and an ignition assembly.

[0029] The vehicle body 1 has openings on both sides along the direction of travel to form a first opening end 11 and a second opening end 12. As the basic structural part of the coal loading car, the vehicle body 1 is the main body that supports other components. The openings on both sides along the direction of travel form two opening ends, providing a structural basis for the coordinated work of subsequent components such as the coal support plate 2 and the rear baffle 4, so that operations such as coal loading and handling of raw coal gas can be carried out in an orderly manner.

[0030] The vehicle body 1 includes two oppositely arranged side plates 13 and a bottom plate 14 connecting the two side plates 13. The two side plates 13 and the bottom plate 14 are arranged in a U-shape. The bottom plate 14 is equipped with wheels so that the vehicle body 1 can move.

[0031] The coal support plate 2 is located at the bottom of the vehicle body 1 and can move on the vehicle body 1 so that the coal support plate 2 can move closer to or further away from the carbonization chamber 3 of the coking oven. The coal support plate 2 includes a first end 21 and a second end 22 arranged opposite to each other, and the coal support plate 2 is used to place coal cakes.

[0032] The rear baffle 4 is disposed inside the vehicle body 1. When the coal-carrying base plate 2 moves to the position of its first end 21 at the first opening end 11 of the vehicle body 1, the rear baffle 4 is locked onto the coal-carrying base plate 2 to close the first opening end 11, and the rear baffle 4 moves with the coal-carrying base plate 2. When the coal-carrying base plate 2 moves to the position of its first end 21 at the second opening end 12 of the vehicle body 1, the rear baffle 4 is locked onto the vehicle body 1 to close the second opening end 12, and the rear baffle 4 does not move with the coal-carrying base plate 2. The rear baffle 4 serves to block coal cakes and assist in controlling smoke and dust.

[0033] The vehicle body 1 is equipped with a drive device for moving the coal support plate 2. The locking method of locking the rear baffle 4 to the vehicle body 1 or to the coal support plate 2 can be a technical means known to those skilled in the art. The connection between the vehicle body 1, the coal support plate 2 and the rear baffle 4 is also a connection method known to those skilled in the art, so it will not be described in detail in this application.

[0034] The ignition assembly is located on one end of the vehicle body 1 near the carbonization chamber 3. The ignition assembly is used to ignite and burn the raw coal gas escaping from the carbonization chamber 3 after the rear baffle 4 is locked on the vehicle body 1, so as to avoid environmental pollution caused by the unorganized emission of raw coal gas.

[0035] In this embodiment, before coal is loaded into the carbonization chamber 3 of the tamping coke oven, the coal cake is placed on the coal support plate 2. When the coal support plate 2 moves to the first end 21 located at the first opening end 11 of the car body 1, the rear baffle 4 automatically locks onto the coal support plate 2, and the two form a relatively closed structure to prevent the coal cake from falling out of the car body 1.

[0036] When coal is started to be loaded into the carbonization chamber 3 of the tamping coke oven, the drive device pushes the coal support plate 2 to move into the carbonization chamber 3 of the tamping coke oven, and the rear baffle 4 moves into the carbonization chamber 3 together with the coal support plate 2, pushing the coal cake into the carbonization chamber 3.

[0037] After the coal cake on the coal support plate 2 is completely fed into the carbonization chamber 3, the first end 21 of the coal support plate 2 is located at the second opening end 12. The lock between the rear baffle 4 and the coal support plate 2 is released, and the rear baffle 4 is locked to the vehicle body 1. At this time, the coal support plate 2 moves back, and the rear baffle 4 no longer moves with it, but instead closes the second opening end 12. Immediately afterwards, the ignition assembly is activated to ignite and burn the raw coal gas escaping from the carbonization chamber 3, so that the raw coal gas is burned under controlled conditions.

[0038] This application, through the ingenious design of the coordinated action of the coal support plate 2 and the rear baffle 4, ensures that the coal cake can be accurately and smoothly delivered into the carbonization chamber 3. At the same time, the ignition component is set up to deal with the escaped raw coal gas in a timely manner, effectively solving the problem of raw coal gas overflowing after coal loading and not being able to be effectively collected, thus reducing environmental pollution.

[0039] In one embodiment, the vehicle body 1 is provided with a rear baffle locking tooth limiter 6. When the coal support bottom plate 2 moves to the position of its first end 21 at the second opening end 12, the rear baffle locking tooth limiter 6 is used to lock the rear baffle 4 located at the second opening end 12 of the vehicle body 1 onto the vehicle body 1 and close the second opening end 12.

[0040] In this embodiment, the rear baffle locking tooth limit 6 is an electromechanical integrated limit locking device installed on the vehicle body 1. Its main function is to lock the rear baffle 4 on the vehicle body 1 when the first end 21 of the coal support plate 2 moves to the specific position of the second opening end 12, so as to ensure that the rear baffle 4 can stably close the second opening end 12 and ensure the smooth progress of subsequent operations.

[0041] When the coal support plate 2 moves to the point where its first end 21 is located at the second opening end 12, the coal loading operation has entered the stage where the coal cake has been completely sent into the carbonization chamber 3. When the coal support plate 2 is about to start moving back, the rear baffle locking tooth limit 6 will activate its locking mechanism. Through mechanical engagement, snap-fit ​​connection or electromagnetic adsorption (depending on its design principle), the rear baffle 4 will be firmly locked onto the vehicle body 1, so that the rear baffle 4 remains stable, creating conditions for the subsequent ignition components to process the escaped raw coal gas.

[0042] The rear panel locking limit 6 of this application can accurately control the locking action between the rear panel 4 and the vehicle body 1, avoiding problems such as untimely or inaccurate locking of the rear panel 4 due to human operation errors or other uncertain factors.

[0043] For example, the rear panel locking tooth limiting 6 includes a locking cylinder and a limit sensor mounted on the vehicle body 1, and also includes a locking tooth connected to the locking cylinder. The limit sensor is mounted on the locking tooth and is used to sense the position of the rear panel. The rear panel 4 has a locking groove that mates with the locking tooth. When the limit sensor senses that the rear panel has moved into position, it sends a signal to the locking cylinder.

[0044] Specifically, when the coal-carrying base plate 2 moves to the position where its first end 21 is located at the second opening end 12, the rear baffle 4 moves to the corresponding position along with the coal-carrying base plate 2. At this time, the rear baffle 4 is in a locking state. The limit sensor senses the rear baffle 4 and sends a signal to the locking cylinder. The locking cylinder starts to work. Under the push of its piston rod, the locking teeth begin to move towards the position where the locking groove is opened on the rear baffle 4, so that the locking teeth lock with the locking groove on the rear baffle 4, locking the rear baffle 47 onto the vehicle body 1, ensuring that the rear baffle 4 will not shift or shake after locking.

[0045] Furthermore, once the limit sensor detects that the locking teeth and locking grooves are fully engaged, it sends a signal to the locking cylinder, causing the locking cylinder to stop working.

[0046] In one embodiment, the rear baffle 4 and the coal support base plate 2 are locked together by mechanical interlocking, snap-fit ​​connection or electromagnetic adsorption (the specific method depends on the design principle), so that the rear baffle 4 can move with the coal support base plate 2.

[0047] In one embodiment, the ignition assembly includes an ignition gun 51, and a control box 7 is provided on the side plate 13. The control box 7 is connected to the rear baffle locking tooth limit 6 and the ignition gun 51 respectively. The control box 7 is used to receive the locking signal issued by the rear baffle locking tooth limit 6, and to control the ignition gun 51 to ignite after receiving the locking signal.

[0048] The side plate 13 is provided with a mounting bracket 52, and the ignition gun 51 is detachably connected to the mounting bracket 52, so that the ignition gun 51 can be easily removed from the mounting bracket 52 when it malfunctions, needs maintenance or replacement.

[0049] The ignition gun 51 is connected to the control box 7 via a cable 53. The cable 53 serves as a wire connecting the ignition gun 51 and the control box 7. It contains a conductive core wire and an insulating outer sheath. Its main function is to establish a stable and reliable electrical signal transmission channel between the two, accurately transmitting the ignition control signal from the control box 7 to the ignition gun 51. This ensures that the ignition gun 51 can execute the ignition action in a timely and accurate manner according to the instructions of the control box 7, thus guaranteeing the smooth progress of the entire ignition process.

[0050] In this embodiment, the ignition gun 51 is the core execution component in the ignition assembly. It is usually a device that uses a mixture of combustible gas and air to ignite and generate a flame. The flame is used to ignite the raw coal gas escaping from the carbonization chamber 3, thereby achieving the combustion treatment of the raw coal gas.

[0051] The control box 7 is an intelligent control unit set on the side panel 13, which plays the role of the control hub of the entire ignition operation. It is electrically connected to the rear panel locking tooth limit 6 and the ignition gun 51 respectively. It can receive the locking signal sent by the rear panel locking tooth limit 6 indicating that the rear panel 4 has been successfully locked on the vehicle body 1. Then, according to the built-in control logic, it analyzes and processes the signal, and then sends an accurate ignition command to the ignition gun 51 to realize the automated control of the ignition process.

[0052] Specifically, when the coal loading is completed, the coal support plate 2 moves to its first end 21 and reaches the second opening end 12 of the car body 1, and the rear baffle 4 is successfully locked onto the car body 1 by the rear baffle locking tooth limit 6, the rear baffle locking tooth limit 6 will immediately generate and send a locking signal to the control box 7.

[0053] After receiving this signal, the signal receiving module inside the control box 7 transmits it to the central processing unit for judgment and confirmation. After confirming that the ignition conditions are met, the output module of the control box 7 sends an ignition command to the ignition gun 51. After receiving the command, the ignition gun 51 starts the internal ignition device, mixes the combustible gas with air and generates a spark at the ignition electrode, and then sprays out a flame to ignite and burn the raw coal gas escaping from the carbonization chamber 3, so that the raw coal gas begins to burn continuously in a controllable state.

[0054] This application achieves close connection and automated coordination between coal loading operation and raw coal gas ignition treatment through intelligent processing of the locking signal of the rear baffle 4 by the control box 7 and precise control of the ignition gun 51. It avoids the drawbacks of untimely and inaccurate operation that may occur with manual ignition, improves the timeliness and success rate of ignition, and ensures that raw coal gas can be effectively and stably combusted.

[0055] In one embodiment, an observation window 8 is provided on the side plate 13. The observation window 8 is used to observe the combustion situation after the ignition component is ignited. The observation window 8 is generally made of materials such as high-temperature resistant and transparent glass. Its position and size are designed according to the needs of facilitating observation of the combustion situation after the ignition component is ignited. The operator can directly observe the flame state, color, size, etc. of the raw coal gas during combustion through this window, so as to promptly detect any abnormal problems that may occur during the combustion process and take corresponding measures.

[0056] In another embodiment, a monitoring device 9 is provided on the side plate 13. The monitoring device 9 is connected to a remote terminal. The monitoring device 9 is used to monitor the combustion status after the ignition component is ignited. The remote terminal is used to receive and display the images captured by the monitoring device 9.

[0057] The monitoring device 9 can be an electronic camera installed on the side plate 13. It usually has functions such as image acquisition and video recording. It can capture the combustion of raw gas after the ignition component is ignited in real time, and convert the acquired image and video data into corresponding electrical or digital signals. It can then establish a connection with a remote terminal through wireless communication methods (such as Wi-Fi, 4G / 5G, etc.) and transmit the on-site combustion scene to the remote terminal.

[0058] Remote terminals are typically computers, tablets, or other display devices located in a control room far from the coal loading site. They have functions such as signal reception, decoding, and image and video display. They can receive combustion information sent by the monitoring equipment 9 and display it clearly on the screen, making it convenient for managers and technicians who are not on-site to remotely view and monitor the data so that they can make timely decisions.

[0059] This application, through the cooperation of monitoring equipment 9 and remote terminal, breaks through spatial limitations and realizes remote real-time monitoring of the combustion of raw coal gas. This allows more personnel who are not on-site to keep abreast of the situation, helps to quickly coordinate and deal with possible problems, and also facilitates long-term recording and analysis of relevant data.

[0060] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
