Adjustable type front mixed abrasive jet flow device

Abstract

The invention relates to the technical field of abrasive water jet flow mechanical equipment, in particular to an adjustable type front mixed abrasive jet flow device. An installing base is included, and supporting legs arranged in a triangular shape are fixedly connected to the upper end of the installing base; the upper ends of the three supporting legs are jointly and fixedly connected with an abrasive tank with an upper end opening; a tank cover is installed at the position of the upper end opening of the abrasive tank; the upper end of the tank cover communicates with a feeding pipe; the bottom of the abrasive tank is arranged conically, and communicates with a discharging pipe; the other end of the discharging pipe communicates with a high-pressure water pipe; a self-discharging mechanism is installed in the high-pressure water pipe; one end of the high-pressure water pipe communicates with a water resource; and the other end of the high-pressure water pipe communicates with a material mixing tank. Due to the adjustable type front mixed abrasive jet flow device, injection of abrasives can automatically stop after flow stopping of high-pressure water flow, waste of the abrasives is avoided, replacing of spraying pipes in different pipe diameters is facilitated, and the width of a cutting line is adjusted.

Description

technical field [0001] The invention relates to the technical field of abrasive water jet mechanical equipment, in particular to an adjustable front-mixing abrasive jet device. Background technique [0002] The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure drop before and after the nozzle outlet section. Usually, the power-driven pump completes a suction and discharge process of water, pumps a certain amount of water to the high-pressure pipeline, and makes it reach the nozzle with a certain amount of energy. The hole diameter of the nozzle is required to be much smaller than that of the high-pressure pipeline, so this certain amount of water reaching the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water that accelerates condensation through the nozzle hole forms a jet. Abrasive jet refers to the jet formed by the high-speed moving abrasive af...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an adjustable front-mixing abrasive jet device, which has the advantages of automatically stopping the injection of abrasives after the high-pressure water flow stops and is convenient for replacing nozzles with different diameters, and solves the waste of abrasives. It will affect the jet cutting again, and the disassembly and assembly of the nozzle is also troublesome.
