PULPING SYSTEM WITH WIND-WATER COUPLED CONNECTION FOR THICKENERS AND A METHOD FOR DETECTING DAMAGED INJECTORS BASED ON THIS SYSTEM Russian patent published in 2023 - IPC E21F15/08 E21F15/00 

FIELD: mining industry.

SUBSTANCE: present invention relates to the field of technology of condensed dewatering of tail sand when filling a mine in the mining industry, more specifically to a pulping system with wind-water coupled connection for thickeners, which is mainly used to activate tail sand for pulping and ejecting sand inside a high-deep cone thickener when filling a mine; this invention also includes a method for detecting damaged injectors. A pulping system with wind-water coupled connection for thickeners and a method for determining the location of damaged nozzles (29) based on this system are proposed, in which three sections of annular tubes are installed at different heights of the wall of the conical pipe section, each section of annular tubes includes an annular water supply (26) and an annular air duct (31). The annular tube is accordingly connected to a pulping nozzle with a wind-water coupled connection (29). The inlet end for the water of the annular water supply (26) is connected to the main water pipe (A) through the water supply pipe (C). The wind inlet end of the annular air line (31) is connected to the main air line (B) through the wind supply pipe (D), the end of the annular water supply (26) is connected to the water outlet collector (E) through a valve; detection pipes are installed between the same section of the water supply pipes (C) and the wind supply pipes (D).

EFFECT: increase in the efficiency of activating tail sands at the bottom of the hopper and avoiding their solidification, increasing the reliability of the device.
