DEVICE FOR CLEANING AND SEPARATION OF LIQUIDS Russian patent published in 1995 - IPC

FIELD: separation of liquids. SUBSTANCE: device has a base, filtering block with filtering membrane-based filtering element inside, inlet and outlet branch pipes, central pipe, clean liquid tank and a system for supplying liquid to be cleaned. The system is provided with tank and pump for feeding the liquid to the filtering block. Besides, the device is provided with header and additional filtering blocks. The header is made in the form of a pipe with opposing branch pipes. All filtering blocks composed as two hydraulically parallel sections are provided with additional branch pipes attached to their corresponding branch pipes of header. Inside each section, the blocks hydraulically communicate with each other in successive order; the filtering elements are made of pipes axially located about each other. One end of each pipe is blind, the other communicates hydraulically with the header. The hollow of the central pipe hydraulically communicates with the non-clean liquid supply system. The filtering blocks are attached to the horizontal carrier by a yoke located on their housing for movement and stoppage. EFFECT: higher efficiency and reliability. 5 cl, 4 dwg
