Description

Moving screen device and generalize waste water treatment apparatus for having circle sediment type with the same}

The present invention relates to a circular sedimentation type total water treatment apparatus, and more particularly, to a circular sedimentation type total water treatment apparatus using a moving screen unit in which a rake is formed on the screen unit and the screen unit is mounted on a screen box and coupled to a conveyor.

Conventionally known circular sedimentation type total water treatment apparatus is known from the Patent Publication No. 10-2004-0106639, and as shown in Figure 1, waste water containing various pollutants are introduced into the inlet through the inlet, waste water The suspended matter contained therein is removed and lifted by the detail screen installed on the inflow path and is formed to be discharged to the outside by the conveyor.

The wastewater from which the suspended matter is removed is introduced into a circular settler along the inlet. The treated water from which the sedimentation is removed from the circular settler is discharged along the outflow path, and the fine contaminants contained in the outflow water are filtered by the fine wood screen installed on the outflow path and lifted by the conveyor and then discharged to the outside.

The effluent from which fine contaminants have been removed flows over the outflow ware installed at the end of the outflow path and flows out from the outlet to the next process. Spillware keeps the water level on the spillway constant so the fine wood screen removes contaminants.

Wastewater from which floating material is removed from the fine screen on the inflow path is tangentially flowed through the inflow path located in the tangential direction at the bottom of the circular settler and rotates along the induction guide plate.

The conical paddle rotates by the operation of the circular settler drive device, and the wastewater rotates according to the inflow amount. The treated water from which the settling was removed is passed to the next process through the outflow path located in the upper tangential direction of the circular settler.

The precipitated sediment is moved to the center by the internal circulation water stream, and the sedimented sediment is collected by scraping the sedimented sediment with a scraper.

The collected sediment is transferred to the sedimentation separator through the lower ejector, washed, and lifted by the sedimentation separator screw and then discharged to the outside. The supply of pressurized water to the ejector is the outflow of the lower part of the outflow ware at the end of the outflow passage. The treated water passed through the fine wood screen from the hopper is pumped through the pump suction pipe, pressurized by the pump, and sent to the ejector inlet connected to the pump discharge pipe. By suction, the sediment is sucked and transferred together with the pressurized water to the sedimentation separator.

The outflow hopper is installed in the lower part of the outflow ware at the end of the outflow in order to discharge the sediment smoothly when the sediment that can be settled on the outflow path due to the flow rate of the wastewater is very small, and the pump suction pipe is connected to the ejector It is used as pressurized water of and sent to sediment separator.

If the inlet and outlet are located opposite to each other depending on the type of treatment plant, it is possible to install the fine screen at the front and the fine wood screen at the rear end based on the circular settler. In a form suitable for use, it is possible to install a screen in front of the circular settler.

The above-mentioned conventionally known comprehensive water treatment apparatus is provided with two or one screener. However, the screen structure for the treatment of the float used in the screening machine is to install the rake (rake) separately from the moving screen to the outside of the cover or the driving unit to remove it, so as to fit the rotation trajectory of the moving screening machine. The design of the correct structure is required, the top structure of the screener is complicated, and the filtering of the float is not smooth.

On the other hand, the moving screen of the integrated water treatment device is to allow one end of the conveyor belt moved by the driving means to be submerged in water and to move the suspended matter in the influent water upwards through the screen structure that is closely attached to the conveyor belt, The screen structure that has filtered the float is transported to the ground along the conveyor belt to separate the float from the float discharge side and then goes down repeatedly, but the wedge bar gap is fixed in the screen structure for treating the float in the wastewater. It is difficult to form such a difficult and heavy weight, such as the combination / welding is inconvenient, the transport, installation of the screen structure is very inconvenient, there was a disadvantage such as increased labor costs by combining the support bar and wedge bar and the fixing frame.

A common problem with the conventional wedge bar combined screen structure is that the wedge bar has a fabrication process to be coupled to the support bar coupled thereto, and in the case of metal, it is to be bonded by adhesive in the case of FRP. In addition, a combination of the manufactured wedge bar and the support bar should be coupled or seated on the support frame again, and a means for connecting the wedge bar integral support frame to both of the rotating conveying chains was also required repeatedly.

The object of the present invention is to provide a circular sedimentation type total water treatment device, which is easy to assemble and screen the screen unit by improving the screen device of the moving screen machine of the conventional circular sedimentation type general water treatment device.
