Said leaktight connection is shown as a longitudinal wall 5 in one drawing. (The drawing shows the long wall on the opposite back side.) The upper and lower edges of the long wall are connected to both pipes 2 and 4. be bombarded with. In this way, an installable unit consisting of a strainer pipe and a receiving pipe is created. 2, 4.5 may be used as the final product of the purification device.

Partially dewatered sewage solids are deposited and layered inside the strainer pipe, resulting in to avoid partially or completely clogging the passage hole 1 and/or the pore 3. In order to The almost solid sewage solids are discharged from the opening 6 at the downstream end of the strainer pipe 2. The scraper/butcher device is a carrier that reciprocates in the axial direction of the strainer pipe 2. The reciprocating motion is based on the movement of the feeding body, and in this example, the reciprocating motion is based on the hydraulic pressure that operates in both directions. It is realized by a driving pressure cylinder 7, a piston 7', and a piston rod 7''.

Connecting members are provided on both end cover sides of the pressure cylinder 7, and are connected to the water penstock 8.9. Subsequently, the penstock is connected to the four-way valve 10. The four-way valve has a high pressure water pipe 11 and a condensate pipe. 12 are connected, and the latter is led to a condensate tank (not shown).

Further, termination switches 13 and 14 are provided at both ends of the pressure cylinder 7, respectively. It is activated by the downstream dog 15 and the upstream dog 16.

As mentioned above, the downstream end of the strainer pipe 2 is used for discharging almost solid sewage solids. An opening 6 is provided for ejection. of the opening to receive the waste. A receptor 17 is provided on the lower side.

The scraper/butcher device has an optimal configuration for the strainer pipe 2. , a plurality of (three in this example) conveyance flaps 18, 18', 18'' are arranged at equal intervals. The conveying flap is arranged directly on the piston rod 7'' or coaxially therewith. or other suitable frame driven by the piston rod 7'' Rotatably installed vertically on the member. In use, the conveyor flap 18.18 '.
