Abstract

The present invention relates to a nonpowered vortex grit removing system which comprises: a circular settling basin having a conical inclination wall and a grit outlet at the bottom portion; an inside separation wall installed inside the circular settling basin; a raw water inlet installed in a tangential direction of one side of the circular settling basin; a treatment water discharge tube connected in a tangential direction of the inside separation wall; a hopper installed at the center of the circular settling basin and connected to a scum discharge tube; and a main shaft screw conveyor installed to be inclined in an upper direction of the grit outlet of the circular settling basin, wherein a guide plate is installed to be oblique with respect to an upper portion of the inside of the raw water inlet along the inflow passage of the raw water between the circular settling basin and the inside separation wall, thereby allowing scum and oil, which float and enter from above, to directly flow into the hopper installed at the center of the inside separation wall, and at the same time, a baffle is installed between the hopper and the treatment water discharge tube, thereby preventing the discharging of the scum and oil through the treatment water discharge tube. Therefore, the scum, oil, and sand contained in the raw water are naturally separated while flowing together with the raw water, and thus can be efficiently removed simultaneously at once, thereby significantly reducing facility investment costs, operating costs, and maintenance costs.

Description

{Non-power Grit Removing System}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-

In wastewater treatment,

And a non-powered swirl-flow desolator remover for separating and removing scum and oil and sand contained in wastewater.

Generally, the wastewater flowing into the wastewater treatment plant is mixed with scum, oil and sand,

During the wastewater treatment, these foreign substances are separated and removed using a desilterizer or the like.

As to the prior art related to such a denuder remover,

In the case of the 'apparatus for treating deposits in sewage and wastewater treatment plants' of Patent No. 10-0433682 (published on May 31, 2004) registered by the applicant of the present invention,

When the centrifugal force is generated by the rotation of the impeller by installing the impeller at the upper part of the central part of the circular inflow tank into which the inflow water flows, the water is discharged through the drainage path by the cyclone principle, and the precipitate having a high specific gravity is collected at the lower part of the cone- The high pressure air injected from an air nozzle formed by twisting the air at an air discharge angle three times is raised in a whirl-like manner by the tornado principle in the suction chamber, and a vacuum pressure is applied to the center of the suction chamber (Negative pressure), so that the precipitate rises together with the high-pressure air floating thereon and is discharged to the outside.

Also, as in the " small swirl-flow deslocation remover " of the Utility Model Registration No. 20-0395073 (published on September 10, 2005), which is also registered by the applicant of the present invention,

The inflow water inlet is inclined downwardly in the inner tangential direction of the settling pit, the process water outlet is provided in the tangential direction on the opposite side of the inflatable pit, the sediment conveying screw conveyor is inclined upward in the center bottom of the settling pit,

The inflow water entering the settling feet forms a swirling flow along the inner side of the settling pit while collecting the sediments such as sand contained in the inflow water into the center of the settled pit and then conveyed to the conveying screw to discharge the settled material, And the water is floated on the upper side of the settling foot and discharged to the outside through the treated water outlet.

However, in this case,

Since an expensive motor driven impeller is used to separate the sand from the wastewater,

There were many facilities investment, operation cost and maintenance cost were required,

In addition, there was a problem of separating only sand from the raw water and separating the scum and oil mixed in the raw water separately,

In the latter case, the inflow water inlet is inclined downwardly in the inner tangential direction of the sludge pit, and the treated water outlet is provided in the tangential direction on the opposite side thereof,

The inflow water entering the settling feet forms a swirling flow along the inner surface of the settling pit while collecting the sediments such as sand contained in the inflow water into the center of the settled pit and then conveyed to the conveying screw to be discharged, The water is floated above the sediment pit and discharged to the outside through the treated water outlet,

Some of the problems caused by rotating the raw water with the impeller have been solved,

There is a problem that only the sand is separated from the raw water and the scum and the oil mixed in the raw water have to be separated by a separate facility.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the conventional swirl-flow deslocation remover,

SUMMARY OF THE INVENTION [0006]

In this state, the automatic valve 15 operated by the sensor or the timer is operated intermittently, and the scum and the oil gathered in the hopper 13 are forcedly sucked by the natural or pump through the scum discharge pipe 17 and discharged to the outside .

On the other hand, the sand mixed with the raw water proceeds together with the raw water along the inner wall surface of the circular gravel 3 and the inner separating wall 5, and then sinks downward due to the load,

Is collected along the inner wall surface of the inclined wall (1) of the circular gravel wall (3) to the lower central portion, and is taken out along the spindle screw conveyor (23) through the needle outlet (21).

The process of separating and removing scum and oil and sand is completed through the above process.
