[0061] Reference Figures 1 to 4 The automatic coke cleaning device for the coke-flowing plate according to an embodiment of the present invention includes a blowing mechanism 100, a coke guide frame 200, a scraper mechanism 300, a distance sensor 400, and an execution module 500. The blowing mechanism 100 is installed between the coke-flowing plate and the coke oven outlet, and is used to blow compressed air onto the surface of the coke-flowing plate. The coke guide frame 200 is movably arranged outside the coke oven outlet and can move to a working position to guide coke at the coke oven outlet. When the coke guide frame 200 can move to the working position, the distance between the coke guide frame 200 and the coke oven outlet is X. A furnace front plate 210 is provided below the coke guide frame 200, and the furnace front plate 210 is located below the coke-flowing plate. The scraper mechanism 300 is installed on the coke guide frame 200 and is driven by the coke guide frame 200. The scraper mechanism 300 moves close to or away from the coke flow plate, and can adhere to the surface of the coke flow plate and move from top to bottom along the coke flow plate; the distance sensor 400 is set at the coke oven outlet, and the distance sensor 400 is used to calculate the distance between the coke guide frame 200 and the coke oven outlet and output the distance information; the execution module 500 is electrically connected to the purging mechanism 100 and is used to control the start and stop of the purging mechanism 100; it is also electrically connected to the distance sensor 400 and receives the distance information from the distance sensor 400; wherein, when the distance between the coke guide frame 200 and the coke oven outlet is greater than X, and the oven door of the coke oven outlet is open, the execution module 500 controls the purging mechanism 100 to start; when the distance between the coke guide frame 200 and the coke oven outlet is equal to X, or the oven door of the coke oven outlet is closed, the execution module 500 controls the purging mechanism 100 to stop.

[0062] In the automatic coke cleaning device for the coke flow plate in this embodiment of the invention, the scraper mechanism 300 is used to scrape most of the coke, coal powder, and tar onto the furnace front plate 210 below the coke guide car frame 200, while the blowing mechanism 100 blows off the small amount of coke, coal powder, and tar remaining on the surface of the coke flow plate after the coke guide car frame 200 has moved away from the coke oven outlet and before the coke oven outlet door is closed (along the coke flow plate). Figure 1 The coke guide car 200 is directed to fall onto the furnace front plate 210 below the coke guide car 200. The execution module 500 controls the start and stop of the purging mechanism 100 by receiving the distance signal from the distance sensor 400, thereby achieving linkage between the coke guide car 200 and the purging mechanism 100 and improving cleaning efficiency.

[0063] Specifically, the cleaning method of the automatic coke cleaning device for the coke spillway plate according to an embodiment of the present invention includes the following steps:

[0064] Step 1: Confirm the furnace number N of the coke oven that has completed the process, then proceed to Step 2;

[0065] Step 2: The coke guide car 200 corresponding to coke oven number N approaches the coke oven and moves to the working distance X, then proceeds to step 3;

[0066] Step 3: Use the coke guide frame 200 to open the furnace door and perform coke guiding operation, then proceed to Step 4;

[0067] Step 4: Drive the scraper mechanism 300 to slide from top to bottom on the coke-flowing plate to scrape off the coke and tar, and proceed to step 5;

[0068] Step 5: Move the coke guide frame 200 away from the coke oven, so that the distance between the coke guide frame 200 and the coke oven outlet is greater than X, and proceed to step 6;

[0069] Step 6: The blowing mechanism 100 is started by controlling the execution module 500. The blowing mechanism 100 blows the coke dripping plate and blows the tar on the coke dripping plate onto the furnace front plate 210.

[0070] Step 7: Close the furnace door and stop the purging mechanism 100 by controlling the execution module 500.

[0071] In summary, by linking the scraper mechanism 300 and the purging mechanism 100, automated operation between mechanical equipment is achieved, replacing the current device and method for manually cleaning the coke spillage plate at the furnace mouth, thereby reducing manual operation time and improving work efficiency.

[0072] Preferably, in order to further improve the linkage effect and the automation effect, in some embodiments, the coke guide frame 200 can be moved to a control position to perform the opening and closing operation of the coke oven outlet. When the coke guide frame 200 can be moved to the control position, the distance between the coke guide frame 200 and the coke oven outlet is Y, where Y > X.

[0073] The automatic coke cleaning device for the coke spillway in the above embodiment includes the following cleaning method, which comprises the following steps:

[0074] Step 1: Confirm the furnace number N of the coke oven that has completed the process, then proceed to Step 2;

[0075] Step 2: The coke guide car 200 corresponding to coke oven number N approaches the coke oven and moves to the working distance X, then proceeds to step 3;

[0076] Step 3: Use the coke guide frame 200 to open the furnace door and perform coke guiding operation, then proceed to Step 4;

[0077] Step 4: Drive the scraper mechanism 300 to slide from top to bottom on the coke-flowing plate to scrape off the coke and tar, and proceed to step 5;

[0078] Step 5: Move the coke guide frame 200 away from the coke oven, so that the distance between the coke guide frame 200 and the coke oven outlet is greater than X, and proceed to step 6;

[0079] Step 6: The purging mechanism 100 is started by controlling the execution module 500. The purging mechanism 100 is used to purge the coke plate and blow the tar on the coke plate onto the furnace front plate 210. At the same time, the coke guide car frame 200 continues to move until the distance between the coke guide car frame 200 and the coke oven outlet is equal to Y. Then proceed to step 7.

[0080] Step 7: Close the furnace door using the coke guide frame 200, and stop the purging mechanism 100 by controlling the execution module 500, then proceed to step 8;

[0081] Step 8: Move the coke guide frame 200 away from the coke oven outlet, and the distance between it and the coke oven outlet is greater than Y.

[0082] In this embodiment, by determining the two working positions of the coking carriage 200 (the working position at a distance of X and the control position at a distance of Y), the linkage between the coking carriage 200 and the purging mechanism 100 can be improved, thereby increasing the degree of automation.

[0083] In some embodiments, the purging mechanism 100 includes a compressed air source 110, a nozzle 120, and a solenoid valve 130. The nozzle 120 is disposed between the coke flow plate and the coke oven outlet. The air inlet end of the nozzle 120 is connected to the compressed air source 110 through an air pipe 140, and the other end faces the surface of the coke flow plate. The solenoid valve 130 is disposed on the air pipe 140 and is used to control the opening and closing of the air pipe 140. The solenoid valve 130 is electrically connected to the execution module 500 and is controlled by the execution module 500 to start and stop. The compressed air source 110 continuously transmits high-pressure airflow to the nozzle 120 through the air pipe 140. The high-pressure airflow is guided by the nozzle 120 and blown onto the surface of the coke flow plate to clean it. The solenoid valve 130 controls the start and stop of the entire purging mechanism 100 by controlling the opening and closing of the air pipe 140.

[0084] Preferably, to improve the cleaning effect, the nozzle 120 is elongated, and its extension direction is consistent with the width direction of the coke-draining plate. The nozzle 120 has multiple air jet holes 121 and a ventilation groove 122. The multiple air jet holes 121 are spaced apart along the length of the nozzle 120. One end of each air jet hole 121 is connected to the ventilation groove 122, and the other end faces the coke-draining plate. The ventilation groove 122 is arranged along the extension direction of the nozzle 120. The air pipe 140 is connected to a fan-shaped ventilation element 141, which is fixedly connected to the nozzle 120 to ensure that the ventilation element 141... The interior of 41 is connected to the ventilation slot 122. The jet hole 121 includes a converging section 1211, a throat 1212, and a diffuser section 1213. Along the flow direction of the compressed gas, the inner diameter of the converging section 1211 gradually decreases and then gradually increases. One end of the throat 1212 is connected to the ventilation slot 122, and the other end is connected to the converging section 1211. Along the flow direction of the compressed gas, the inner diameter of the throat 1212 gradually decreases. One end of the diffuser section 1213 faces the coke flow plate, and the other end is connected to the converging section 1211. The inner diameter of the throat 1212 gradually increases. During the flow of high-pressure gas through the jet orifice 121, the flow velocity of the high-pressure gas is first accelerated, and then concentrated and diffused, so that it is fully dispersed to the surface of the entire coke flow plate, effectively cleaning each area of ​​the coke flow plate. Furthermore, from the acceleration in the contraction section 1211 to the low-pressure state in the throat 1212, and then to the deceleration and static pressure recovery in the diffusion section 1213, the entire flow process has a certain directionality and stability, which plays a guiding role in the high-pressure gas flow (along...). Figure 4 (Arrow) to prevent high-pressure airflow from being dispersed in an undirected manner.

[0085] In some embodiments, the scraper mechanism 300 includes a first drive module 310, a swing arm 320, a second drive module 330, a connecting rod 340, a third drive module 350, a blade holder 360, and a scraper 370; one end of the swing arm 320 is rotatably connected to the bottom of the coking carriage 200, and the other end is rotatably connected to one end of the blade holder 360; a first rotating seat 321 and a second rotating seat 322 are provided on the side of the swing arm 320 near the end of the coking carriage 200; one end of the first drive module 310 is rotatably connected to the side wall of the coking carriage 200, and the other end is rotatably connected to the first rotating seat 370. The seat 321 is rotatably connected; the middle part of the connecting rod 340 is pivotally mounted on the lower half of the swing arm 320; one end of the third drive module 350 is rotatably connected to one end of the connecting rod 340, and the other end is rotatably connected to the middle part of the blade holder 360. The third drive module 350 is elastic, so that the blade holder 360 swings downward; a scraper 370 is fixedly connected to the side of the blade holder 360 away from the third drive module 350; one end of the second drive module 330 is rotatably connected to the second rotating seat 322, and the other end is rotatably connected to the end of the connecting rod 340 away from the third drive module 350.

[0086] In the scraper mechanism 300 of this embodiment, the first drive module 310, the swing arm 320, the tool holder, and the coke guide carriage 200 form a first linkage 340 mechanism; the second drive module 330, the linkage 340, the third drive module 350, and the tool holder form a second linkage 340 mechanism; wherein, the tool holder serves as the connecting component between the first linkage 340 mechanism and the second linkage 340 mechanism; the first drive module 310 directly drives the swing arm 320 to rotate, thereby causing the entire tool holder to slide along the coke flow plate (from... Figure 2 Location changed to Figure 3 The third drive module 350 moves by swinging the drive linkage 340, which in turn drives the third drive module 350 to move. The movement of the third drive module 350 can move the cutter holder away from or closer to the coke flow plate. Furthermore, the direct drive of the cutter holder by the third drive module 350 can make the front scraper 370 fit against the coke flow plate when the cutter holder is close to the coke flow plate, thus cleaning the coke flow plate.

[0087] Specifically, the first drive module 310, the second drive module 330, and the third drive module 350 are all cylinders.

[0088] Preferably, the first rotating base 321 includes two connecting rods, one end of which is fixedly connected and rotatably connected to the first drive module 310, and the other end is fixedly connected to the swing arm 320, so that the two connecting rods and the swing arm 320 form a triangular structure. This improves the stability of the connection structure between the first drive module 310 and the swing arm 320.

[0089] In some embodiments, the coke guide frame 200 is slidably connected to a guide rail 220, which is positioned above the coke oven outlet. This serves to guide the coke guide frame 200 (along...) Figure 1 Arrow B).

[0090] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
