Description

Technical Field

[0001] The utility model belongs to the technical field of coking, and in particular relates to a device for preventing material from slipping off a vibrating feeder. Background Art

[0002] like Figure 1 As shown, in the CDQ coke discharge system of a coking plant, coke is discharged from the CDQ furnace 100, passing through the flat gate 200, the inlet compensator 300, the inlet chute 400, and the material trough 600. After being vibrated by the vibrating feeder 500, the coke enters the rotary seal valve 900 through the outlet compensator 700 and the outlet chute 800. The vibrating feeder 500 is the core power device, responsible for discharging a fixed amount of cooled coke from the CDQ furnace and feeding it into the rotary seal valve 900. After a period of operation, even if the vibrating feeder 500 is shut down, coke may still flow into the lower rotary seal valve 900, causing material slippage. If production personnel fail to detect this problem and shut down the rotary seal valve 900 in a timely manner, the rotary seal valve 900 may become blocked, preventing normal operation and impacting CDQ production. The main reasons for the material slipping phenomenon are: 1. The lining of the vibrating feeder trough 600 is worn and smooth, so that the friction of the lining is less than the downward force generated by the gravity of the coke; 2. The inlet chute 400, the vibrating feeder trough 600, etc. are damaged due to the friction of the coke for a long time, and are not repaired in time, which increases the angle of repose and causes material slipping; 3. Coke quality problems, such as changes in particle size, cause material slipping. When the material slipping phenomenon occurs, the commonly used methods are: 1. Welding a coke baffle at the bottom outlet of the trough 600 to block the coke or welding a wear-resistant layer on the lining. This method requires personnel to enter the trough 600 of the vibrating feeder. Because there is carbon monoxide inside the trough 600, there is a great risk, and it takes a long time, which has a great impact on the dry quenching production; 2. Replace the liner of the trough 600 with a new one to increase the friction resistance. Since there are many trough liners, replacement time is long and they generally need to be replaced during maintenance. 3. Adjust the angle of the vibrating feeder 500 to change the repose angle. This method has little impact on CDQ production, but due to space limitations such as the vibrating feeder inlet compensator 300, outlet compensator 700, and outlet chute 800, the angle adjustment is limited to a certain range and can only be a temporary solution. It cannot solve the problem of sinking to the bottom. Summary of the Invention
