泥分を洗滌分離したのち、篩渣脱水機に導入して圧搾脱
水している。Conventionally, in sewage treatment plants, a dust remover is installed at the entrance of the settling basin, and the sieve residue that has accumulated in front of the dust remover's entrance is scraped up and separated, and this scraped up sieve residue is then introduced into the washing tank. After washing and separating the sand and mud, it is introduced into a sieve residue dehydrator and compressed and dehydrated.

ようにしている。Figure 1 schematically shows an example of 70-, in which sieve sludge scraped up by a mulch removal machine is conveyed by an endless conveyor, and the washed sieve sludge is conveyed to a sand washing machine and washed by a dewatering machine. I'm trying to narrow it down.
上述の説明でも明らかなように、従来の洗滌脱水装置で
は掻き上げた篩渣を再び洗滌機に投入して洗滌したのち
、この洗滌したｌＩＩ＃ｔを脱水するようにしている。As is clear from the above description, in the conventional washing and dewatering apparatus, the scraped sieve residue is put into the washer again and washed, and then the washed lII#t is dehydrated.

の設置にも広鱒敷地を要する。In other words, the sieve residue that has been scraped up and drained by the dust remover is put back into the water for washing, and the wet sieve residue is then dehydrated. The cleaning equipment installed during transport is large and requires a large area of trout land to install a processing facility.

In addition to supporting a cone-shaped feed shaft wound with
The small diameter part of the feed shaft extends from the bottom of the hopper, and the cleaning water supply path provided in the small diameter part opens in the inlet of the screen drum. It was established.

リーンは粗目のものを用いるは勿論である。This invention is constructed as described above, and the sieve residue put into the hopper is conveyed into the screen drum by the blades of the feed shaft, and first, the sieve residue is washed with washing water spouted from the feed shaft at the inlet. After the sand, mud, etc. are washed and separated, only the sieve residue is sent to the large diameter part of the feed shaft, where it is compressed and dewatered, and taken out from the other end of the screen drum. Washing of residue and compression dehydration are performed at the same time, eliminating the need for conventional washing ponds, etc.
. In addition, in this invention, the screen drum is rotatably supported, and the cleaning nozzle is provided around the rotation of the screen drum, so that even if the screen drum becomes clogged during cleaning and dewatering, it can be cleaned and recycled. Continuous operation is possible. It goes without saying that the screen at the inlet of the screen drum should have a coarse mesh.
以下、図面に随ってこの発明を具体的に説明する。Hereinafter, this invention will be specifically explained with reference to the drawings.
