Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of riser pipes, in particular to a coking-resistant ramming coke oven riser pipe. Background Art
[0002] A ramming coke oven is a type of oven used in the coking process. It uses a tamping machine outside the oven to compact the coking coal into briquettes, which are then pushed from the side of the oven into the carbonization chamber for high-temperature carbonization. It is suitable for coking high-volatile, weakly cohesive coal. The riser is a crucial component of the ramming coke oven. Located at the top of the oven, its primary function is to drain the raw gas from the carbonization chamber to the gas collecting pipe. Typically made of high-temperature, corrosion-resistant steel and cylindrical in shape, the riser can regulate the pressure within the carbonization chamber to a certain extent. Routine maintenance requires frequent inspection of the joint seals to ensure leak-tight extraction of the raw gas. External insulation and refractory materials must also be maintained, and temperature changes monitored to ensure stable operation and production efficiency. However, existing ramming coke ovens are prone to increased smoke production during coking due to excessive oxygen content. Therefore, controlling the oxygen content of the raw gas can reduce the additional smoke generated by inhaled air and minimize the escape of smoke from ramming coke ovens.
[0003] Patent CN202116496U discloses a ramming coke oven riser arrangement structure, characterized in that the riser is arranged on the coke side of the coke oven top, the riser is connected to the bridge pipe, valve body, and gas collecting pipe arranged on the coke side in sequence, and a high-pressure ammonia injection device is installed on the bridge pipe; the ramming coal loading machinery is installed on the coke oven machine side; the device uses the negative pressure generated by the high-pressure ammonia injection device on the coke side bridge pipe on the coke oven top to quickly introduce the raw coal gas generated during the ramming coke oven coal loading through the riser and effectively control the oxygen content of the introduced raw coal gas, which solves the problem of smoke dust escaping from the ramming coke oven coal loading. However, during daily use, a large amount of tar adheres to the inner wall of the pipe body, which is difficult to clean and easily leads to blockage of the pipe mouth, reducing the service life of the pipe body. Utility Model Content
[0004] The purpose of the utility model is to provide a ramming coke oven riser that reduces tar accumulation on the inner wall of the riser, avoids clogging of the pipe body, prolongs the service life of the pipe body, and is easy to operate, so as to solve the technical problem that tar is easily adhered to the inner wall of the riser, is difficult to clean, and thus causes clogging of the pipe mouth and reduces the service life of the pipe body.
[0005] In order to solve the above technical problems, the solutions adopted by the present invention are as follows:
[0006] and a tube connecting the discharging opening of the heat exchanger and the control device, wherein the tube has a first end connected to the tube by a first valve and a second end connected to the control device, wherein the first valve and the second valve bodies are connected to each other with a steam pipe, and high-temperature steam is injected into the heat conduction plate through the first valve body and the second valve body, so that the heat conduction plate becomes hot and the tar adhering to the surface is melted. The nozzle is installed at the upper end of the connecting pipe through the regulating device, and the nozzle is connected to a high-pressure jet device externally, which sprays gas through the nozzle at the lower end of the nozzle to blow the melted tar out of the pipe body and flow downward.
[0007] Furthermore, the heating device includes a fixing plate and a threaded sleeve. The bottom end of the fixing plate is rotatably connected to the adjustment device, and the top end is threadedly connected to the threaded sleeve. The rotatable fixing plate can adjust the inclination angle of the nozzle to conform to the inner wall of the pipe body. The nozzle is fixedly mounted on the fixing plate via the threaded sleeve. The threaded sleeve installed on the top end of the fixing plate can be used to fix and connect the nozzle to the external gas pipe, ensuring stable gas delivery to the nozzle head of the nozzle and preventing gas leakage.
[0008] Furthermore, the adjustment device includes a servo motor, a fixed sleeve, a guide plate, a gear, and a sliding sleeve; the guide plate is fixedly mounted at the top of the connecting pipe; the sliding sleeve is slidably connected to the guide plate; one end of the fixed sleeve is fixedly connected to the sliding sleeve, and the other end is fixedly connected to the servo motor; the output end of the servo motor is fixedly connected to the gear. The servo motor drives the gear to rotate, causing the sliding sleeve to slide on the guide plate, causing the fixed plate at the top of the sliding sleeve to drive the nozzle of the nozzle to slide along the guide plate, causing the nozzle to rotate in a circular motion on the guide plate at the top of the connecting pipe, thereby evenly blowing air into the pipe body and guiding the melted tar to flow out.
[0009] Furthermore, the lower end surface of the connecting tube is provided with drive teeth that mesh with the gear. When the gear at the output end of the servo motor rotates, it moves on the drive teeth, driving the nozzle to slide along the guide plate, allowing the nozzle to evenly blow air into the interior of the tube at different locations, ensuring that tar adhering to various parts of the tube is effectively melted and blown out, avoiding blind spots.
[0010] The working principle of this utility model is as follows:
[0011] When in use, the steam pipe is connected to the first valve body and the second valve body, and the external air pipe is connected to the nozzle of the threaded sleeve; high-temperature steam is injected into the heat conduction plate through the first valve body and the second valve body to make the heat conduction plate hot and melt the tar adhered to the surface, and at the same time the nozzle ejects gas through the nozzle to blow the melted tar out of the pipe body and flow downward. While the nozzle is ejecting gas, the servo motor is started, and the servo motor drives the gear to rotate, so that it makes a circular motion on the drive wheel, and drives the sliding sleeve to slide on the guide plate through the fixed sleeve, and then drives the nozzle on the fixed plate at the top of the sliding sleeve to make a circular motion along the guide plate, so that the nozzle of the nozzle can evenly blow air into the inside of the pipe body at different positions, ensuring that the tar adhered to various parts of the pipe body can be effectively melted and blown out, avoiding cleaning dead corners.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The utility model transmits high-temperature steam to the heat conduction plate through the first valve body and the second valve body of the heating device, melts the tar adhering to the surface of the heat conduction plate, and then blows the melted tar out of the pipe body by ejecting gas, thereby improving the cleaning efficiency, effectively reducing the blockage caused by tar accumulation, ensuring the smooth flow of the riser, ensuring the smooth discharge of raw gas, reducing the tediousness and danger of manual cleaning, and extending the service life of the pipe body.
[0014] 2. The utility model drives the gear to rotate and move on the driving wheel through the servo motor of the adjustment device, driving the nozzle at the top of the sliding sleeve to move along the guide plate, so that the nozzle can evenly blow air into the inside of the pipe body at different positions, ensuring that the tar adhered to various parts of the pipe body can be effectively melted and blown out, avoiding the occurrence of cleaning dead corners, and improving the efficiency and quality of cleaning.
