Phrase It is made.

The operation and effects of the present invention having the configuration as described above will be described.

First, the turbid water generated during the operation of extinguishing the red coke in the fire extinguishing tower 130, which is a fire extinguishing facility, is drained into the sedimentation tank 140 through a drainage passage 145 installed between the digestion tower 130 and the settling tank 140. You will go through the path. Accordingly, when the turbid water generated in the digestion tower 130 flows rapidly through the drainage passage 145, the first operating plate 11 is disposed in the middle of the drainage passage 145 so as to face the turbidity flow. Since both left and right ends of the upper pivot shaft 13 of the first operating plate 11 are assembled to pivot, the operating plate 11 is pivotally flowed with the upper pivot shaft 13 as the rotation center.

The lower end of the first operating plate 11 is pivotally operated in the flow direction of turbid water, while the lower end of the first operating plate 11 is installed at a right angle to the upper pivot shaft 13 of the first operating plate 11, and the wire 20 The operating arm 13 connected to the top is pivoted in the opposite direction to the flow of turbid water as opposed to the above.

In this case, when there is no flow of turbid water in the drain 145, one end is connected to the first operating plate 11, which maintains the vertical initial state, and the wire 20, which maintains the tension, is formed. When the 1st operation plate 11 turns to flow, it loosens and moves to the 2nd operation plate 12 side along the guide rollers 25a, 27a, 27b of the 1st, 2nd guiders 25, 27.

Subsequently, when the wire 20 is loosened, the second operation plate 12 connected to the other end of the wire 20 is the first operation plate 11 in an initial state which is pivoted upon expansion of the wire 20. As opposed to the upward swing operation of the up and down turns and is converted to a vertical state, it blocks the upper space of the dam 155 that the treated water precipitated in the sedimentation tank 140 overflows.

Accordingly, even though turbid water is rapidly introduced into the settling tank 140 through the drainage passage 145, the second operating plate which is turned downward in a vertical state as opposed to the first operating plate 11 which is turned upward by the rapid flow of the turbid water. By blocking the upper portion of the dam 155 by the (12) can be prevented from flowing into the clean basin 142 side through the filter box 146 to overflow the dam (155) will be.

Meanwhile, when the flow of turbid water flowing in one direction through the drainage passage 145 gradually decreases and flow stops, the first operation plate 11 installed in the drainage passage 145 and pivoted upward when excessive turbidity flows is While turning down about the upper pivot 13 so as to return to a vertical state by its own weight and the weight of the weight 19 installed thereon, the upper working arm 15 is turned upward while being loosened. 20) is pulled to have a taut initial state.

In this case, the second operation plate 12 connected to the other end and the lower end of the wire 20 is pulled upward with respect to the upper pivot 14 to open the upper space of the dam 155. . Accordingly, the treated water introduced into the sedimentation tank 140 and the powdered coke is precipitated flows over the upper portion of the dam 155 to the filter box 146 and then reused as the digestive water. It is supplied to the side.

According to the present invention as described above, by opening and closing the upper space of the dam where the turbid water flowing into the sedimentation tank in accordance with the flow of turbid water flowing along the drainage channel, the turbid water is not precipitated in the sedimentation tank immediately to the Clean Basin side Since it can prevent the inflow, it is possible to smoothly recycle the digestion water by preventing the blockage of the water pump due to the sediment of the turbid water directly entering the clean basin when the sedimentation level rises due to the excessive inflow of turbid water. In addition, it is possible to prevent the shortage of fire extinguishing water and to perform the fire extinguishing process stably without equipment interruption accident.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
