Abstract

Equipment for biologically purified wastewater purification by mechanical means. It has a hollow drive shaft which is used to drain the purified water mechanically and receive a circular disc-lined filter unit. Each unit consists of a sector frame surrounded by a perforated filter made of textile. Or other material And allow pure water to pass through the shaft The latter rotates in the wastewater mass in the container so that the water flows through the strainer into the frame and then into the shaft. The filter interferes with the contaminants that are eliminated through pipes that flank the filtering unit And connected to a mechanical device to generate a separate suction structure to the shaft

Claims (8)

1.Round disc filters (1) for the purification of bio-treated wastewater. Which has a circular disc of the filter which is driven And disc style filters, each with two (6) filter surfaces Which can be cleaned by suction, the suction device (24) extends radially upward to the support pipe (7), giving it a characteristic whereby the support tube (7) has a polygonal cross-section. , Where its flat side surfaces (13) are attached directly to the detachable frame (12) each separate frame covered by a filter cloth, which together forms a body. Of the polygonal filter (5) and where the suction device (24) has a suction nozzle (23) which is subdivided into a group of chambers (25,26,27), each chamber was Defined as the different radial sections of the filter body (5) and where the chamber (25,26,27) was created with a reduced suction cross-section (28,29, 30) from Inside to outside 2. The device according to claim 1, is characterized by providing a support pipe (7), a hexagonal cross-section, and a frame (12) attached to the support pipe (7). ) Has formed a pentagon when viewed from the side, so the body of the filter (5) is a twelve-sided disc. 3. The equipment according to claim 2 is characterized by providing a support pipe (7) with a hexagonal cross-section. And the frame (12) attached to the support tube (7) was built with four sides as viewed from the side, thus resulting in a hexagonal disc-shaped filter body (5). 4.Equipment according to one or more of any of the preceding claims, is characterized by the fact that each frame (12) has a pipe which is radially extended (14) for supporting bolts ( 15) For reinforcing scaffolds (12) and support tubes (7). 5. The equipment according to one or more of the preceding claims, is characterized by the fact that the frame (12) has a trapezoidal recess surrounding (18) on its periphery. Where a long strip (19) makes a suitable configuration required for mounting the filter cloth (20) 6. Equipment according to one or more of the preceding claims, is characterized by the frame (12) having a lattice frame (22) on both sides. 7. Equipment according to the claim No. 1, Characterized by providing three chambers (25,26,27) with the inner chamber having the largest suction cross-section, where the outer chamber has the smallest suction cross-section. And where the value of the suction cross-section of the middle chamber is between the suction cross-section of the inner and outer chamber. 8.Equipment, according to one or more of the preceding claims, is characterized by the filter cloth (20), making it a bag-like configuration through which the frame (12) can be pulled.
