FIELD: process engineering. ^ SUBSTANCE: invention relates to maintenance appliances for fluid transfer pipeline networks and can be used as additional device preventing accumulation of mud in pipelines. Proposed mud filter comprises casing accommodating water feed branch pipe, purified water discharge branch pipe and drain system. Said casing houses partially perforated branch pipe connected with purified water discharge branch pipe, and represents horizontal or inclined cylinder with a hatch welded into one of its sides to inspect and repair mud filter. Damping plate is arranged below said filter. Purified water discharge branch pipe is mounted on the same side, right above casing axis, drain system first branch pipe is mounted below said axis. Water feed branch pipe is arranged on casing opposite side below casing axis and second drain branch pipe is arranged above said axis to remove floatable impurities from casing. Both pipeline and casing has at least one perforated hole closed by elliptical shirt tail. Additional drain branch pipe is arranged at casing lower part nearby aforesaid damping plate, while elliptical baffle is mounted opposite the water feed branch pipe. ^ EFFECT: higher efficiency. ^ 2 cl |
