CERAMIC FILTERING ELEMENT AND METHOD FOR PRODUCTION THEREOF

摘要

The invention relates to filtering devices, in particular to the structural design of the filtering elements of disc ceramic filters and to methods for the production thereof. In order to increase the performance and the strength of a device, the inventive ceramic filtering element comprises a hollow block made of porous ceramic material whose inside elements are arranged in rows and offset along the arcs of a concentric circle and form with walls (4) a hollow volume (3). The ratio of the radius of the transition line between walls inside the hollow block (1) in the bottom part (6) of a sector element with respect to the radius of said interface line in the top part thereof rages from 0.5 to 0.75. An outlet fitting (7) is connected to the hollow block (1) with the aid of a screw joint provided with a seal (8). The inventive method for producing a ceramic filtering element consists in producing the replication thereof of a mixture of paraffin hydrocarbons, forming a porous blank by compaction and using vibration load, and, in order to protect environment, in removing the material of said replication at a temperature below the inflammability point of paraffin hydrocarbons.
