FIELD: mining.SUBSTANCE: device contains tubular casing, filtering module installed in the casing and containing filtering pipe with slotted channels, fairing installed at side of the input part of the filtering pipe, input and output bushings. The filtering pipe is connected by thread joint with the output bushing, the filtering module creates inside the casing a cavity to receive the mechanical admixtures. The filter has thread adapter rigidly connected with the output part of the casing with possibility of disconnection. The centring strake in the input part of the tubular casing is made with the transverse ring shoulder. The input bushing is made with ribs directed outside and is telescopically connected by end faces of the said ribs with the centring strake in the input part of the tubular casing, and is thread connected with the filtering pipe, and is made with the internal ring strake and ring groove located on its internal ring strake. The fairing is telescopically connected with the input bushing in the internal ring strake of the input bushing, and is provided by the lathe mechanism in form of the collet end of the fairing equipped with the external ring strake interacting with the ring groove of the input bushing. At the face end of the fairing the catching rod is installed to catch and to raise to the surface, and to release the central channel of the filter for raising to the surface of the remote control system module.EFFECT: extended process abilities, simplified design.2 cl, 6 dwg |
