Conventionally, settling tanks in sewage treatment facilities for human waste and other wastewater have not been equipped with devices for removing bulky waste, resulting in various problems such as the generation of scum and foreign objects getting stuck in the pump during subsequent treatment steps. Some sewage treatment facilities have a screen installed inside the settling tank, but the sieve sludge is dehydrated outside the tank, which causes bad odors and other problems during transfer of the sieve sludge, as well as the installation space. There were also problems.

As shown in FIG. 2, the screen 6 is made up of a plurality of bars 6a arranged at equal intervals and assembled together with through bolts 6b. Pressure roller 8 above
The shaft is supported by a bearing 10, and is pressed toward the guide roller 9 by a spring 11 as shown in FIG. In the figure, 10' is a bearing cover. As shown in FIG. 4, both rollers 8 and 9 have an inner cylinder a made of a steel pipe and a soft rubber outer skin b baked onto the outer periphery. As shown in FIG. 2, the pressure roller 8 has a sprocket wheel 12 attached to the extending portion of its shaft passing through the tank wall, and a motor 13 drives the chain 20.
It is driven and rotated through. Of course, the expansion or loosening of the chain 20 caused by the movement of the shaft of the pressure roller 8 in the spring direction is automatically adjusted by the spring support of a chain guide pulley (not shown). Also, 14
is the sieve residue guide plate attached to the top of the screen,
15 is a scraper provided in contact with the pressure roller 8 for peeling off the dewatered sieve residue adhering to the pressure roller 8; 16 is provided in contact with the guide roller 9; the other end reaches the receiving basket 17; A guide roller scraper 19 also serves as a guide for the dewatered sieve residue, and numeral 19 indicates a rake for scraping up the sieve residue stuck to the front surface of the screen 6 and placing it on the sieve residue guide plate 14 when operated by the worker M.

In the above configuration, the liquid to be treated that flows in from the inlet 3 passes through the screen 6, and those having a high specific gravity settle on the bottom of the tank, and the supernatant liquid to be treated flows out from the outlet 4 and is transferred to the next step. Therefore, the height of the outlet 4 regulates the height of the liquid level W in the tank. The coarse sieve residue stuck on the screen 6 is scraped off by driving the motor 13 to rotate the pressure roller 8 via the chain 20 and sprocket wheel 12 at the appropriate time, and then by the operation of the worker's rake 19. The roller is lifted up, passed through the guide plate 14, and is caught between the pressure roller 8 and the guide roller 9. Here, the water-containing sieve residue is dehydrated by the pressure of the pressure roller 8, passed through the scraper 16, and stored in the receiving basket 17, and is removed from the tank at the appropriate time. As such, unsanitary problems during transportation are extremely rare. Further, foreign matter such as empty cans mixed in the liquid to be treated is scooped up with a scooping net or the like in front of the screen and stored in a foreign matter receiving basket 18, and is removed separately at the time of draining. Regardless of the size of the sieve residue supplied to the pressurized sieve residue dewatering device 7, the axial movement of the pressure roller 8 by the spring 11 is possible, so that appropriate pressure dewatering is performed. In addition,
The interval between the bars 6a of the screen is set to an appropriate interval depending on the type of liquid to be treated, etc.

以上のように、本考案は槽内で粗大篩渣を除去

As described above, this invention not only removes coarse sieve residue inside the tank and eliminates the various problems that occurred with conventional systems, but also has a dewatering device outside the tank similar to that used in some conventional systems. Therefore, it can be said that this is an excellent sand settling tank in terms of equipment costs and space utilization.
