Efficient double-cavitation abrasive material jet flow nozzle

Abstract

The invention relates to an efficient double-cavitation abrasive material jet flow nozzle. The efficient double-cavitation abrasive material jet flow nozzle comprises a high-pressure nozzle, a low-pressure nozzle, a center body main body and two connecting pipes which are oppositely arranged left and right. The interior of the high-pressure nozzle is hollow along the axis of the high-pressure nozzle, and a high-pressure cavity is formed. The high-pressure nozzle is coaxially sleeved with the low-pressure nozzle, the high-pressure nozzle and the low-pressure nozzle are connected and sealed through an end cover, and a low-pressure cavity is formed. The low-pressure nozzle is provided with a plurality of fluid inlets at intervals in the ring direction of the low-pressure nozzle, and the fluid inlets communicate with the low-pressure cavity. The center body main body is coaxially sleeved with the high-pressure nozzle, the interior of the center body main body is hollow along the axis of the center body main body, and an abrasive material slurry cavity is formed. One ends of the connecting pipes sequentially penetrate through the high-pressure nozzle, the low-pressure nozzle and the side wall of the center body main body and communicate with the abrasive material slurry cavity. According to the efficient double-cavitation abrasive material jet flow nozzle, the characteristics of low pressure and strong turbulent flow of fluid in the tail area of the center body main body in the high-pressure nozzle are ingeniously utilized, abrasive material slurry and double-cavitation jet flow are sufficiently mixed, accordingly, double-cavitation abrasive material jet flow is formed through mixing, and accordingly the jet flow hitting effect is improved.

Description

technical field [0001] The invention relates to a jet nozzle, in particular to a high-efficiency double cavitation abrasive jet nozzle. Background technique [0002] High-pressure jet jet technology is widely used in mining, machinery, municipal, construction and other industries due to its unique cold cutting advantages. High-pressure jet jet technology is formed by converting the pressure energy of water into the kinetic energy of the jet stream through a nozzle of a specific shape through the principle of liquid pressurization. The nozzle is the only element in the high-pressure jet stream that converts pressure energy into jet kinetic energy. The energy distribution characteristics of the beam have an extremely important influence on the working efficiency of the jet. [0003] Cavitation jet is a new type of jet. By using cavitation nozzles (such as self-vibration cavitation nozzles, center body nozzles, angle nozzles, etc.) The instantaneous high temperature and high-...

Problems solved by technology

[0005] The nozzles disclosed in the prior art can only use the cavitation jet or the abrasive jet alone. If a new type of nozzle with both the cavitation jet and the abrasive jet can be invented, it will greatly promote the improvement of the working efficiency of the water jet.
