The coke tower is the reactor of the coking unit. When the coke tower is working, the coking heavy oil conveyor belt in the external heating furnace needs to be driven into the coke tower to carry out coking and decoking. The coke fragments produced during the long-term production process of the coke tower are easy to flow back into the feed pipeline, causing the pipeline to be blocked. Therefore, it is necessary to regularly clean the feed port at the bottom of the coke tower. The traditional cleaning method is to remove the pipeline and clean the feed port with a brush, scraper and other cleaning devices. The blocked coke fragments are not easy to clean, and the cleaning process is time-consuming and laborious. Therefore, it is necessary to develop a coke tower feeding mechanism that can facilitate the cleaning of the coke tower feed port and achieve continuous production during the cleaning process.

[0013] The utility model will be further described below in conjunction with the accompanying drawings.
[0014] like Figure 1 A coke tower feeding mechanism shown in the figure includes a coke tower 1, a feed pipe is connected to the bottom of the coke tower 1, a flange is provided at the end of the feed pipe, and is connected to a raw material supply device through the flange, a connecting frame 2 is fixedly connected to the outside of the feed pipe by bolts, the upper end of the connecting frame 2 is fixed to the outer wall of the feed pipe, and a lifting mechanism is provided on the connecting frame 2, the output end of the lifting mechanism is fixedly connected to a sealing end cover 3, a rotating rod 4 is rotatably connected to the sealing end cover 3, a crushing knife 5 is fixedly connected to the upper part of the rotating rod 4 above the sealing end cover 3, a scraper 6 is fixedly connected to the rotating rod 4 above the sealing end cover 3, a spare feeding pipe 7 is fixedly connected to one side of the lower part of the coke tower 1 above the feed pipe, a valve 8 is connected to the spare feeding pipe 7, and the spare feeding pipe 7 is connected to a discharge pipe of the raw material supply device through a flange. It should be noted that in the present embodiment, the lifting mechanism drives the sealing end cover 3 to rise so that the sealing end cover 3 can completely close the feed pipe, and the lifting mechanism drives the sealing end cover 3 to descend, which can leave enough space for the flange connection between the raw material supply device and the feed pipe. In order to facilitate the connection, the output pipe of the raw material supply device adopts a bendable hose.
[0015] In order to facilitate the stable lifting and lowering of the sealing end cover 3 and ensure the sealing stability between the sealing end cover 3 and the feeding pipe during the cleaning process of the feeding pipe, the lifting mechanism includes a screw 9, a motor 13, and a sliding rod 10. The screw 9 is rotatably connected to one side of the connecting frame 2 through a bearing, and the other side is fixedly connected to the sliding rod 10. A threaded block 11 is threadedly connected to the screw 9, and a sliding block 12 is slidably connected to the sliding rod 10. The threaded block 11 and the sliding block 12 are respectively fixedly connected to the two sides of the sealing end cover 3. The motor 13 is fixedly connected to the connecting frame 2 through a motor mounting seat, and the output shaft of the motor 13 is fixedly connected to one end of the screw 9.
[0016] In order to conveniently drive the rotating rod 4 to rotate, drive the crushing knife 5 and the scraper 6 to operate, and realize the cleaning of the inside of the feed pipe, the lower end of the rotating rod 4 is fixedly connected with a hand wheel 14.
[0017] In order to further improve the sealing performance between the sealing end cover 3 and the feed pipe, the spare feeding pipe 7 is used to continue production during the cleaning of the feed pipe. A sealing gasket is fixedly connected at the corresponding position between the top of the sealing end cover 3 and the lower end surface of the feed pipe.
[0018] In order to facilitate the use of the scraper 6 to scrape off the sticky materials on the inner wall of the feed pipe, the scraper 6 is in an "L" shape, and one side of the scraper 6 is in contact with the inner wall of the feed pipe. It should be noted that in this embodiment, the scraper 6 is made of a bending-resistant material.
[0019] It should be noted that a limiting plate is fixedly connected to the rotating rod 4 , and the limiting plate is located above the sealing end cover 3 , and can limit the rotating rod 4 to prevent it from falling.
[0020] The working process of this embodiment is as follows:
[0021] After the coke tower 1 has been working for a long time, the feed pipe is prone to blockage. At this time, the feed pipe needs to be cleaned. When cleaning the feed pipe, the pipe connected by the flange between the feed pipe and the raw material supply device is disassembled, and then the motor 13 is controlled to run. When the motor 13 is running, it drives the screw 9 to rotate. When the screw 9 rotates, it drives the threaded block 11 to move upward, thereby driving the sealing end cover 3 to move upward and fit the lower end surface of the feed pipe for sealing. Then, the discharge pipe of the raw material supply device is connected to the spare feeding pipe 7, and the valve 8 is opened for feeding, so that the coke tower 1 continues to operate, and the cleaning of the feed pipe does not affect normal production. Grab the hand wheel 14 and turn it. The hand wheel 14 drives the rotating rod 4 to rotate. During the rotation of the rotating rod 4, the crushing knife 5 and the scraper 6 are driven to rotate. The crushing knife 5 can crush the coke fragments blocked in the feed pipe, and the scraper 6 can quickly scrape off the attachments stuck on the inner wall of the feed pipe. After cleaning the feed pipe, control the motor 13 to run. When the motor 13 runs, it drives the screw 9 to rotate. When the screw 9 rotates, it drives the threaded block 11 to move downward, thereby driving the sealing end cover 3 to move downward away from the feed pipe. After processing the crushed and scraped coke fragments and other impurities, reconnect the raw material supply device to the feed pipe, and close the valve 8 on the feeding pipe 7.
