Then, the condensate conveyed by the conveying screw 31 through the conveying pipe 32 is compressed and dehydrated by the condensate conveyed subsequently while contacting the bent pipe 34, the desorption liquid generated by the dehydration is drained After flowing into the through hole 35 and collected in the collecting unit 36, it flows into the case 11 through the desorption liquid moving tube 37.

In addition, a plurality of drainage holes 38 are formed on the lower surface of the transfer pipe 32 corresponding to the collection hole 33, and with the contaminants falling into the transfer pipe 32 through the collection hole 33. The incoming washing water is to be properly drained into the drum screen (13).

In addition, the controller 40 detects the water level rising by the sewage flowing into the drum screen 13 by the water level sensor 41 installed inside the drum screen 13, and then detects the water level. When the water level is higher than the reference level through the information to operate the pump for injecting the washing water into the motor 21 and the washing water spray pipe 22 to operate the washing unit 20 and the contaminant discharge unit 30 at the same time.

In addition, the conveying vane 137 is to be transported upwards during the rotation of the contaminants accumulated on the inner surface of the wedge wire 134 into the drum screen (13).

Therefore, the present sewage treatment apparatus is configured to continuously process the impurities contained in the sewage with a simple structure.

Figure 4 is an operating state diagram of the present invention, Figure 4a is a side cross-sectional view showing a treatment state, Figure 4b is a side cross-sectional view showing a washing state, Figure 4c is a front sectional view showing a washing state, Figure 4d is a washing state It is an enlarged sectional view of the main part.

Referring to Figure 4 described the operating state of the present invention.

As shown in FIG. 4A, the sewage flowing into the drum screen 13 through the inlet 14 falls downward while filtering contaminants through the wedge wires 134 of the drum screen 13. The drum screen 13 is discharged to the outside of the case 11, that is, inside.

Then, the filtered water discharged into the case 11 is discharged to the outside through the discharge port 12 installed on the lower side of the case (11).

As such filtration continues and contaminants accumulate inside the drum screen 13, sewage flowing into the drum screen 13 is filtered out of the drum, and thus is not properly discharged. Your sleep will rise.

As shown in FIG. 4B and FIG. 4C, if the sewage flowing into the drum screen 13 is not properly discharged and the surface is raised, the water level sensor 41 detects the elevated surface. Information sensed by the detection sensor 41 is input to the controller 40.

The controller 40 receiving the information on the water level from the water level sensor 41 drives the motor 21 to allow the washing water to flow into the washing water injection pipe 22.

As such, when the motor 21 and the washing water spray pipe 22 are operated by the controller 40, the washing water is sprayed through the spray nozzle 23 while the drum screen 13 is rotated by the motor 21. Therefore, the contaminants stuck to the drum screen 13 are dropped into the transfer pipe 32 through the collecting hole 33.

The washing water introduced together with the contaminants falling into the transfer pipe 32 through the collecting hole 33 is properly drained into the drum screen 13 through the drain hole 38.

Then, the miscellaneous material dropped into the conveying pipe 32 through the collecting hole 33 is conveyed to one side by a conveying screw 31 which is interlocked with the motor 21, and the miscellaneous material is continuously conveyed to the bent pipe 34. It is hit.

The contaminants that hit the bend tube 34 are then compressed by other contaminants to be transported to discharge the desorption liquid through the drain hole 35.

In addition, the desorption liquid discharged through the drain hole 35 is collected in the collecting unit 36 and is introduced into the case 11 through the desorption liquid moving tube 37 to be discharged through the outlet 12.

In addition, after the debris is compressed in the bending tube 34 is desorbed is pushed along the bending tube 34 is discharged to the outside.

In addition, the contaminant accumulated in the drum screen 13 is rotated in a state caught in the transfer vane 137 attached in an oblique direction along the inside of the wedge wire 134 is detached by the washing water sprayed from the top.

As shown in FIG. 4D, the washing water flowing into the washing water spray pipe 22 is sprayed inclined to the outer circumferential surface of the drum screen 13 while passing through the inclined spray nozzle 23, thereby increasing the washing efficiency.

When the contaminants accumulated on the drum screen 13 are removed through the process as described above, and the filtration of sewage is performed smoothly, the water level is naturally lowered, and accordingly, the controller 40 of the motor 21 and the washing water spray pipe 22 is removed. The operation is stopped to return to the state of FIG. 4A while stopping the rotation of the drum screen 13.

As such, the sewage treatment apparatus continuously removes contaminants contained in the sewage while washing and filtration are repeatedly performed in the filtration state and the rotating state in the stationary state.

On the other hand, as shown in Figure 5 is an enlarged cross-sectional view of the main portion showing another embodiment of the present invention, the configuration of the present invention will be described as follows.

The sewage treatment apparatus is configured to be provided with a scraping unit 50 to remove the contaminants scraping the outer surface of the drum screen 13 inside the case 11 to the outside of the drum screen 13.

In a more detailed configuration, the scraping unit 50 is a brush 51 provided horizontally to abut the outer circumferential surface of the drum screen 13, the bending plate is fixed to the brush 51 and bent at a predetermined angle ( 52, an elbow-shaped fixing plate 53 to which the bending plate 52 is attached, and a brush mounting plate 54 to which the fixing plate 53 is fixed and mounted inside the case 11.

In addition, a depth adjusting screw 55 is fastened to be movable up and down along the bending plate 52 and the brush 51 is fixed, and the fixing plate 53 is elastic by a torsion spring S. A rotating shaft 56 is provided to be rotatably mounted in a supported state, and is provided with an angle adjusting screw 57 that is vertically coupled to the fixed plate 53, and abuts against a lower end of the angle adjusting screw 57. The fixing jaw 58 is attached to the brush mounting plate 54, and the stopping jaw 59 is attached to the brush mounting plate 54 so as to stop after one end of the fixing plate 53 is reversely rotated. will be.

Here, when the drum screen 13 is rotated, the scraping part 50 allows the brush 51 to naturally scratch the outer circumferential surface thereof so that the contaminants caught between the gaps of the wedge wire 134 enter the inside.

And, the brush 51 is provided in contact with the outer surface of the drum screen 13 in a state of having a predetermined angle by the bending plate 52, the depth of the brush 51 is worn and its length is shortened After loosening the adjusting screw 55, the length of the brush 51 is adjusted by moving downward.

In addition, the brush 51 is properly adjusted by the shankdong of the angle adjusting screw 57, which is rotated up and down by rotating the angle adjusting screw 57 to the lower end of the angle adjusting screw 57 The fixing plate 53 is rotated along the rotation shaft 56 by the abutment fixing jaw 58 to be angularly moved up and down, such that the bent plate 52 is angularly moved so that the angular movement of the brush 51 is performed.

In addition, the elastic movement according to the angular movement of the brush 51 is implemented by the torsion spring (S) provided on the rotating shaft (56).

In addition, when the drum screen 13 is reversely rotated, the fixing jaw 58 is rotated while the brush 51 moves backwards, and thus the fixing jaw 58 is caught by the stopping jaw 59 and its rotation is performed. As the movement is appropriately limited, easy restoration by the torsion spring S is achieved.

Therefore, even when the drum screen 13 is rotated in reverse, the brush 51 is rotated at a predetermined angle by the rotating shaft, so that the brush 51 and the bending plate 52 are rotated by the reverse rotation of the drum screen 13. Breakage is properly prevented.
