Description

Sedimentation Sludge Hopper Gate {SLUDGE HOPPER GATE FOR SEDIMENTATION BASIN}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for smoothly removing sludge adhering to side surfaces of a sedimentation hopper in sedimentation basins used in sewage treatment plants, wastewater treatment plants, and water purification plants.

In general, the sedimentation basin is to perform the function of sedimentation, buffering, and discharging the turbidity, and therefore, the sedimentation inlet is most effectively precipitated and discharged to ensure good sedimentation efficiency at all times. If the sludge is not discharged smoothly, the sludge accumulates and causes deterioration of water quality. The accumulated sludge causes the sludge collector to malfunction or degrade its function.

Figure 1a relates to removing the sedimentation sludge using a sludge collector, when the turbidity introduced into the sedimentation basin is accumulated by gravity at the bottom of the sedimentation basin, the sedimented sludge is collected by the sludge collector and collected into the sedimentation hopper, The sludge collected and stored in the hopper relates to the removal of the sludge through a sludge outlet provided at the lower side of the hopper by a constant interval or continuously.

This discharge is usually intermittent, so sludge builds up and accumulates inside the hopper and sticks to the inner wall of the hopper. The sludge collected in the sedimentation basin hopper is normally discharged smoothly with a water content of 97-98%, but the sludge accumulated on the inner wall of the hopper is not discharged. Therefore, the sludge is discharged smoothly on the center of the hopper centered on the sludge outlet, but the sludge fixed on the inner wall of the hopper is not discharged properly, which reduces the volume of the hopper and the amount of sludge collected by the sludge collector In addition to the side effect that the sludge is accumulated outside the hopper because it can not be stored, sediment water that should not be discharged than the sludge is discharged, which hinders the efficient water quality management of the treatment plant. If the above phenomenon is repeated, only a part of the collected sludge in the hopper is discharged, and the sludge accumulated on the inner wall of the hopper remains as it is, so that the sludge collected by the sludge collector is not collected in the hopper but accumulates on the inlet side of the sedimentation basin. If this phenomenon is repeated, it will not discharge the sludge collected and collected continuously, resulting in deterioration of the original function of the sedimentation basin.

Figure 1b is to improve the above problems, the submersible pump is installed below the sedimentation frost line, a plurality of injection nozzles are installed at equal intervals on the inner side wall of the hopper, and connected to the pipe pressure pressure of the pump It is an apparatus for the purpose of discharging the sludge fixed on the inner wall of the hopper by spraying the nozzle using.

However, the injection method using the submersible pump as described above may remove a portion of the sludge within the range in which the nozzle pressure is attached and the sludge stuck to the lower part of the hopper still has a problem, and a bigger problem is the nozzle Sludge rises due to vortex during spraying and scum, which may adversely affect the sedimentation basin.

Therefore, the sludge discharge method used up to now has low utilization of sludge hopper, so sludge discharge is not easy, and it is difficult to maintain the entire sedimentation basin and difficult to control water quality. There is an urgent need to improve the device.

The present invention, in order to solve the above problems, by using a hopper closing means made of a flat plate or cylinder or other shape, opening and closing the settling hopper portion, when closing the settling hopper portion hopper closing means at least one side of the settling hopper side Forming a gap with the water between the hopper closing means is introduced into the high pressure to remove the sludge attached to the clarifier hopper side portion provides a settling sludge hopper gate to prevent the sludge from rising to the hopper closing means.

In addition, the present invention, when the hopper closing means closes the sedimentation basin hopper, the auxiliary hopper closing means made of a flat plate or cylinder or other shape is installed on the side or bottom of the hopper closing means to adjust the gap between the inflow into the gap It provides a settling sludge hopper gate to control the water pressure and speed of the water.

Therefore, the auxiliary hopper closing means opening and closing control device 264 rotates around the auxiliary hopper closing means opening and closing control device shaft 262.

When the auxiliary hopper closing means opening and closing control device 264 is rotated, the auxiliary hopper closing means opening and closing control shaft 266 moves in the longitudinal direction of the opening and closing control shaft 266. One end of the auxiliary hopper closing means opening and closing control shaft (266) is connected to the auxiliary hopper closing means opening and closing control device (264) rotates around the auxiliary hopper closing means opening and closing control device shaft (262), but ignores the length of the rotating arm Ignoring the rotation angle can be seen that the opening and closing adjustment shaft 266 moves in the longitudinal direction of the opening and closing adjustment shaft 266.

When the opening and closing adjustment shaft 266 moves, the length adjusting means 268 moves, and when the length adjusting means 268 moves, the length adjusting means connecting link 270 moves in the length direction of the length adjusting means connecting link 270. do.

When the length adjusting means connecting link 270 is moved, the auxiliary hopper closing means shaft connecting link 272 connected to the length adjusting means connecting link 270 rotates about the center point of the auxiliary hopper closing means shaft 274.

When the auxiliary hopper closing means shaft connecting link 272 is rotated, the auxiliary hopper closing means shaft 274 fixed and connected to the other end of the auxiliary hopper closing means shaft connecting link 272 is connected to the auxiliary hopper closing means shaft rotating cylinder 282. Supported and rotates.

As the auxiliary hopper closing means shaft 274 rotates, the auxiliary hopper closing means 286 fixed and connected to the auxiliary hopper closing means shaft 274 rotates to form a gap formed between the hopper closing means 200 and the settling hopper H. Adjust the interval between At this time, by operating the length adjusting means 268 or the auxiliary hopper closing means opening control wire (294) it is possible to adjust the interval of the gap between the auxiliary hopper closing means 286 and the side of the sedimentation basin hopper (H).

As mentioned above, although this invention was demonstrated to the said Example, this invention is not limited to this.
