Description

Screen device for removal of sewage in the sewage {a device for screen with exclusion of an adulterated materials in waste water}

The present invention relates to a screen device for removing sewage in the sewage, and more specifically, to a screw conveyor and a conveyance for transporting the traps collected by the trap and the screen of the trap and sediment captured by a certain amount deposited in the treatment tank to remove the impurities. It relates to a screen device for removing sewage in the sewage to prevent the accumulation of sewage in the sewage treatment plant and the like as the compression-extrusion screen is connected to the screen body.

In general, sewage, sewage, and manure must be treated in a purification facility and discharged into the stream. The purification facility is a pretreatment process that processes sediments and sewage from various fruits and seeds in sewage, sewage, and manure. There is a post-treatment process in which chemicals and microorganisms are injected into sewage and sewage or treated by precipitation.

As described above, the pretreatment process is removed from the wood screen, the fine screen, and the settling basin, depending on the size of the soil and various contaminants introduced into the sewage treatment plant.

In this case, a method of pulling up the debris on the screen by vibrating or catching the debris on the screen or by using a rotating drum screen is used.

However, contaminants should be screened and removed well. Existing devices, such as bodies, bars, or drums, are easily blocked and cannot be processed in a timely manner. As a result, it is often transported to the next process, which shortens the time for depositing sediment at the second place.

The apparatus for removing the contaminants for solving such a problem, as shown in Figure 1, the treatment tank 10; Screens are installed to be inclined by the plurality of support frames 11 inside the treatment tank 10, the hopper 12 is connected to the lower end thereof, the drive motor 13 and the impurities discharge port 14 is connected to the top Body 20; A first cylindrical screen (30) installed in a porous cylindrical shape in which a driving means is connected to one side so as to rotate while maintaining concentric circles with the screen body (20); A second screen 40 having a plurality of through holes 31 formed at an upper portion of the screen body 20 and having a water tank 32 connected to the outside thereof; and, being installed to rotate in the screen body and the extrusion part screen. It comprises a screw conveyor 50 is connected to the spiral braid is connected to the opposite direction on both sides, and consists of a configuration in which the brush 15 and the nozzle 16 is installed on the upper portion of the first screen 20 .

Such a contaminant removing device, the screw conveyor 50 is installed inside the screen body 20 when power is transmitted to the drive motor 13 after the sewage containing the contaminant is supplied to the treatment tank 10 and The first screen 30 is rotated while maintaining a constant reduction ratio.

At this time, the first screen 20 is rotated while depositing a predetermined portion inclined to the sewage inclined to raise the contaminants therein, at this time the brush 15 and the nozzle 16 are sprayed to drop the contaminants, After being introduced into the hopper 12, the screw is compressed to the second screen 40 while rising as the screw conveyor 50, and discharged to the contaminant discharge port 14 installed at one side thereof.

However, in the above-mentioned debris removal device, seeds or the like are squeezed on the porous screen to block the through-holes of the screen, and the screen is maintained in the same diameter so that compression is inefficient and the braid is forward and Composed in the reverse direction to destroy the compacted contaminants to increase the volume, there is a disadvantage such as requiring a high pressure and a large flow rate for removal of the contaminants.

An object of the present invention for improving the above disadvantages, to prevent the screen clogging phenomenon, to easily separate the attached impurities of the screen, to modify the shape of the screen to improve the compression efficiency, It is to provide a screen device for removing the sewage in the sewage to prevent the crushing of the high-compression rate of the discharged debris.
