FIELD: machine building.SUBSTANCE: ceramic sector element of the disk filter includes two filtering layers separated by spacers and internal chamber, connected by means of the manhole and hollow shaft with the distributing head of the filtering unit. The internal chamber is made as set of two cavities, each of them is made as system of radial and transverse tubular channels connected with each other as network distributed with uniform density in the ceramic material at one of the filtering surfaces of the sector. The radial channels of each cavity are connected with each other and with radial channels of the other cavity in another plane in the central part of the sector, and are connected to two branches located with displacement relatively to each other in transverse direction. The filtering unit for suspension separation contains a casing, a bath for suspension, a rotating hollow shaft with secured disk filtering elements assembled out of the ceramic sectors with the internal chamber. The internal chamber is connected by the branch duct with the shaft cavity and with the distribution head connected to the vacuum pump.EFFECT: increased reliability of the filtering unit due to increased strength of the ceramic sector of the filtering element under the hydraulic impact loads upon regeneration of the sector filtration properties.5 cl, 4 dwg |
