SLURRY HYDRAULIC ELEVATOR Russian patent published in 2023 - IPC F04F5/02 

FIELD: hydraulic elevators.

SUBSTANCE: jet devices designed for pumping contaminated media, in particular for removing sludge and large particles ranging in size from 0.5 to 20 mm. The slurry hydraulic elevator contains a nozzle (1) coaxially attached to the discharge pipe (2), a receiving chamber (3), according to the invention, the receiving chamber (3) is made open, and its length K is K = 2·d_c (1); where K is the length of the receiving chamber, mm; d_c is the diameter of the nozzle outlet diameter, mm, and is set based on the dimensions of the inlet diameter d₁ and the outlet diameter d_c of the nozzle (1), which correspond to the following ratio d_c/d₁ = 0.2÷0.33, and the size of the outlet diameter of the nozzle (1) d_c is 10÷50 mm and the inlet diameter of the nozzle (1) d₁ is 50÷ 150 mm, and the length l₂ of the nozzle (1) and the length l₄ of the discharge pipe (2) correspond to the following ratio l₂/l₄ =0.09÷0.013, and the size of the length l₂ of the nozzle (1) is 70÷208 mm and length l₄ of the discharge pipe (2) is 650÷2100 mm. This ensures an increase in the service life and efficiency of the slurry hydraulic elevator; it can be used in emergency situations and for hydraulic removal of secondary dust.

EFFECT: increasing efficiency and simplifying the design.
