Description

Technical Field

[0001] The utility model relates to the technical field of water seal grooves, in particular to a machine coke side water seal groove capable of realizing automatic water supply and drainage functions. Background Art

[0002] The water seal tank on the coke side is a U-shaped tank filled with water. The smoke generated by the coke oven when loading coal or pushing coke is introduced into the ground dust removal station through the water seal tank. However, long-term operation will cause particles in the flue gas to enter the water seal tank and deposit on the bottom wall. If it is not cleaned regularly, the particles will gradually accumulate, affecting the normal operation of the water seal tank and even accelerating equipment wear.

[0003] In order to prevent this from happening, a manual drain valve is usually installed under the water seal tank. The function of these manual drain valves is to discharge the particles while draining water to prevent them from accumulating on the bottom wall of the water seal tank. When the liquid level in the water seal tank drops, water is replenished manually.

[0004] The manual drain valve needs to be operated regularly to clean the particles in the water seal tank, which requires additional manpower and time. During the drainage process, the liquid level in the water seal tank must be observed at all times and water must be added when necessary, which increases the complexity of the operation. In addition, after the particles in the water seal tank accumulate on the bottom wall of the water seal tank for a long time, the particles will adhere to the bottom wall of the water seal tank. When draining, they cannot flow away with the water flow, causing scaling on the bottom wall of the water seal tank, which in turn affects the normal operation of the water seal tank.

[0027] Furthermore, the receiving pipe 51 has a funnel-shaped structure; the main function of the receiving pipe 51 is to receive the diameter difference between the fixed pipe 5 and the manual butterfly valve 52, thereby ensuring the sealing and stability of the pipeline connection.

The control box 4 can achieve the left and right reciprocating movement of the scraper 8 by changing the direction of the reduction motor 85, so that the use effect of the scraper 8 is better. It should also be noted that the moving rod 82, the fixing frame 81 and the scraper 8 are integrally cast or welded, and the outer side is coated with waterproof coating to ensure that it can adapt to the long-term underwater working environment.

[0029] Furthermore, a fixing seat 7 is fixedly connected to the center position of the top wall of the water seal groove 1, a reduction motor 85 is fixedly connected to an inner side of the fixing seat 7, an end of the threaded rod 84 away from the reduction motor 85 is rotatably connected to the inner wall of the fixing seat 7, and an end cover 71 is fixedly connected to the upper surface of the fixing seat 7 by bolts; the end cover 71 adopts a detachable structure, which is convenient for subsequent maintenance and inspection of the reduction motor 85 and other components.

[0030] Furthermore, a through groove 16 is opened on the inner side of the partition 15, and the through groove 16 passes through the top wall of the water seal groove 1 and is connected to the fixed seat 7, and the moving rod 82 is slidably connected inside the through groove 16; the through groove 16 is used to connect the water seal groove 1 and the fixed seat 7, and provides a moving path for the sliding of the moving rod 82, and can also play a limiting role for the moving rod 82.

[0031] Furthermore, two groups of inclined guide slopes 17 are symmetrically provided on both sides of the inner bottom wall of the water seal groove 1, and the bottom surface of the scraper 8 is in contact with the guide slope 17; the guide slope 17 is inclined, and its main function is to ensure that the sediment in the water seal groove 1 slides as close to the drain hole 14 as possible. Even if a small amount of sediment adheres to the surface of the guide slope 17, it will gradually slide towards the drain hole 14 under the scraping of the scraper 8.

[0032] Working principle: The control box 4 is used to control the operation of related electrical equipment, so that the water inside the water seal groove 1 is discharged regularly, realizing the function of automatic drainage, and at the same time, the particulate matter in the water seal groove 1 is discharged; then the liquid level monitor 3 installed on the upper surface of the water seal groove 1 is used to monitor the liquid level height inside the water seal groove 1 in real time, and the control box 4 is used to control the water pump 21 to automatically pump water from the water tank 23, thereby realizing the function of automatic water replenishment.

[0033] The specific method is as follows: in the first step, the control box 4 controls the electric butterfly valve 54 to open, so that the water inside the water seal groove 1 flows into the fixed pipe 5 through the drain hole 14, and finally flows into the drain pipe 6; in the second step, when the electric butterfly valve 54 is opened, the control box 4 controls the reduction motor 85 to operate, and the reduction motor 85 drives the threaded rod 84 to rotate through the coupling, and when the threaded rod 84 rotates, it drives the nut seat 83 to move in the horizontal direction, and then drives the moving rod 82 to move in the horizontal direction, and the moving rod 82 then drives the scraper 8 to scrape back and forth on the bottom wall of the water seal groove 1 through the fixed frame 81. When the scraper 8 scrapes back and forth, the particles deposited on the bottom wall of the water seal groove 1 are scraped up and flow out of the drain hole 14 with the water; in the third step, the liquid level monitor 3 is installed inside the water seal groove 1. The liquid level sensor 31 monitors the liquid level height inside the water seal groove 1 in real time. When the liquid level monitor 3 detects that the liquid level height inside the water seal groove 1 reaches the lower limit value (the lowest water level in the water seal groove 1 must always be higher than the lowest end of the partition 15), the electric butterfly valve 54 is controlled to close to complete the drainage; the fourth step is to control the operation of the water pump 21 through the control box 4, and the water pump 21 pumps the water in the water tank 23 to the inside of the connecting pipe 2 through the pumping pipe 22, and then flows into the water seal groove 1 through the connecting pipe 2 and the water inlet pipe 13. When the liquid level monitor 3 detects that the liquid level height inside the water seal groove 1 reaches the upper limit value (the highest water level in the water seal groove 1 must always be higher than the lowest end of the inlet pipe 11), the water pump 21 stops operating, thereby completing the automatic water supply work.

[0034] It should be noted that all the electrical equipment mentioned above are electrically connected to the control box 4 and can be controlled by the control box 4. At the same time, the control box 4 can be connected to the remote control system to realize the remote automatic water supply and drainage function of the water seal tank 1.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
