Description

Gate sealing device of sedimentation channel

The present invention relates to a gate device for controlling the sedimentation basin channel, and more specifically, a sedimentation facility for separating the coke generated from the process of extinguishing the coke extruded from the coke oven into a fire truck and extinguishing it with water. The present invention relates to a gate sealing device of a sedimentation basin channel which can prevent safety accidents in advance and greatly reduce downtime of equipment due to its excellent sealing ability for the gates provided in the system.

In general, the red coke extruded from the coke oven is loaded into a fire truck to be digested with water in a fire extinguishing tower. The water and the coke generated during the extinguishing process go through a precipitation facility (1) as shown in FIGS. 1 and 2. Collected separately from each other.

That is, the water containing the powdered coke flowing along the channel 20 of the sedimentation equipment 1 is sent to the primary sedimentation tank 21 through the first gate 11 opened and opened in the direction of arrow A. The powdered coke settled to the bottom of the settling tank 21 is collected by the chain scraper 32 circulated by the motor 31 of the drive device 30, while the gates 2 and 3 opened 12 and 13 are opened. Water flowing in the direction of arrow B through) reaches the 4th settling tank 24 through the 2nd and 3rd settling tanks 22 and 23, and the water reaches the tank of the digestion tower using a water pump. It is transported into the water and reused when extinguishing the red coke.

In this normal operation, the water and the powdered coke produced during the digestion of the red coke are collected by transporting the natural coke along the channel 20 of the sedimentation plant 1 to the precipitated coke as the chain scraper 32. Collect it for digestion and recycle. At this time, unlike the gates 11, 12, 12, and 13 that are opened, the gate 14 of the fourth gate is closed.

On the other hand, water containing powdered coke is opened along the water channel 10 when the equipment for checking or maintaining equipment such as the chain scraper 32, the bottom liner and the bearing installed in the primary settling tank 21 is stopped. After passing through the fourth gate 14, the second and third sedimentation tanks 22 and 23 flow through the open gate 23, and the water reaching the fourth precipitation tank 24 is Similarly, it is stored in the tank of the digestion tower as a water pump. At this time, the heavy coke powder is accumulated in the second, third and fourth sedimentation tanks (22), (23), and (24), and when it cannot be removed in a timely manner, the water pump is sealed by closing the suction line of the water pump. It can be difficult to extinguish red coke because it can't be pumped into the tank of the digestion system, and it can cause huge trouble in operation.

When the equipment is stopped for facility inspection and repair as described above, the first and second gates 11 and 12 are closed, and the third and fourth gates 13 and 14 are open.

Conventionally, the manual handle 16 of the gate plate 10 to block the first, second, and second gates 11, 12 by two workers when the facility is stopped for maintenance and inspection of the substructure of the precipitation facility 1 as described above. ) And then move it to the gate (11), (12) position and move it to the 'c' guide groove (15a) of the concrete frame (15) as shown in Figure 3 (a), (b) By fitting, because the waterway 20 must be shut off, the worker's workload was very large and there was a problem that the work switching was not quick.

In addition, although the actual work of preventing the gate gap formed between the conventional gate plate 20 and the concrete mold 15 using asbestos rope, cement, etc. was performed separately, it is difficult to completely seal the water through the gate gap. There was a problem coming to the first settling tank 21, which is a working place. As a result, there is a risk of safety accidents during the maintenance of the facility, and if the downtime of the facility is prolonged due to the interruption of inspection and maintenance work, it accumulates in the second, third, and fourth settling basins 22, 23, and 24. Since the amount of powdered coke is gradually increased, there is a problem of causing trouble and cost increase to collect the collected coke powder using bucket crane.

Therefore, the present invention has been devised to solve the problems described above, the purpose of which is to completely seal the gate gap so that water containing powdered coke is not introduced into the work place during maintenance and inspection of the precipitation facility. It is intended to provide a gate sealing device for a sedimentation channel to prevent safety accidents and to quickly switch opening and closing operations of the gate plate, and to drastically shorten operation normalization and maintenance time.
