DEVICE FOR ASEPTIC CLEANING OF WELLS Russian patent published in 2025 - IPC E21B37/00 

FIELD: mining.

SUBSTANCE: invention relates to mining, namely to devices intended for mechanical and biological cleaning of a well. Proposed device comprises rope-cable and working tool. Rope-cable is fixed on top in cable lock, lower end of which is detachably connected to electric compartment, in which rope-cable is connected to pump, and then with ultraviolet light sources. Electrical compartment lower part is rigidly jointed with pump compartment accommodating the pump. At the lower end of the pump compartment, a working tool is fixed, in which there is a central suction channel, a header and horizontal hydraulic channels that are oriented tangentially to the well walls. Lower end of the working tool is rigidly connected to the ultraviolet processing compartment, inside which ultraviolet light sources are installed with the possibility of detachment. Lower part of the ultraviolet processing compartment is rigidly connected to the filter compartment, inside of which mechanical cleaning filters are mounted with possibility of detachment. Filters are made in the form of a cylinder from metal mesh with different cell sizes and are installed in series in ascending cell size. Filter with large size of cells should be lower, check valve is rigidly installed on lower end of filter compartment.

EFFECT: improving efficiency of aseptic cleaning of wells.
