EJECTOR WITH SLOT FREE VORTEX ACTIVE NOZZLE AND STRAIGHT MIXING CHAMBER Russian patent published in 2024 - IPC F04F5/10 

FIELD: mining.

SUBSTANCE: invention relates to ejectors and can be used for pumping media containing mechanical impurities or aggressive, corrosive components from various pits, buried reservoirs, for cleaning wells, wells and other equipment. Invention is intended for pumping various media, pumping of which is problematic with the help of usually used equipment, namely different types of pumps - centrifugal, gear, rotary, that is having a complex structure with internal parts (chambers, blades), which can be rendered useless by this pumped medium. Such a medium can be various corrosive liquids (acids, alkalis, etc.) or inhomogeneous media with high content of abrasive and mechanical impurities. Thus, in cases where conventional pumps may fail in the process of pumping or break down before the specified service life, it is possible to use an ejector, the design of which allows creating a vacuum without using complex internal devices. Objective of the claimed invention is simpler design of the method of pumping out the medium from buried equipment by connecting it to the pumping pipeline. Main advantage of the invention, which creates a vacuum for the purpose of pumping media, consists in the simplicity of its design with respect to the method of connecting to the pumping pipeline, and features of the design of the jet apparatus significantly increase its efficiency due to the use of an auto-adjustable free-vortex active nozzle.

EFFECT: use of this invention will make it possible to reduce operating costs for repair of pumping equipment, while prime cost of manufacturing of jet pump is considerably less than manufacturing of a standard pump.
