Grinding material continuous and automatic feed device capable of achieving pressure stabilization and flow stabilization

Abstract

The invention discloses a grinding material continuous and automatic feed device capable of achieving pressure stabilization and flow stabilization. The device comprises a control module, dual spherical high-pressure grinding material tanks, high-pressure water pipelines, low-pressure water pipelines, feeding pipelines, a grinding material water jet pipeline, valves and sensors, wherein the valvesand the sensors are arranged on the pipelines. Valve seats of the dual spherical grinding material tanks are connected with the feeding pipelines, the high-pressure water pipelines and the low-pressure water pipelines. Water pumps are connected with above function devices through high-pressure pipelines, overflow valves, a main proportional flow valve, a bypass proportional flow valve, pneumaticball valves and high-pressure ball valves are arranged in the pipelines, and various functions are achieved through valve on-off combined control. In the device, operation of pure water jet and continuous and automatic grinding material water jet is achieved through system valve on-off combination; meanwhile, through cooperation of the sensors connected to the control module, an energy accumulatorand the flow valves, pressure stabilization and flow stabilization can be achieved, and automatic adjustment of the grinding material concentration and overpressure alarm can be achieved. The deviceis high in safety, simple in operation and capable of being used widely.

Description

technical field [0001] The invention belongs to the field of mechanical abrasive jet, in particular to an abrasive water jet continuous automatic operation device. Background technique [0002] Water jet technology is a new technology developed in modern times. It is widely used in industry, and can be used for jet cutting, rock drilling, material surface cleaning, drilling and mining, etc. Due to the high pressure required for industrial use of pure water jet and the high requirements for pumps, it is difficult to popularize and use. Therefore, scholars have developed abrasive water jet technology. This solid-liquid two-phase medium jet has a good cutting effect and can be used Promotional use. Abrasive jet technology can be divided into pre-mixed abrasive jet and post-mixed abrasive jet due to different mixing methods. Due to the uneven mixing of abrasives and water, the post-mixed abrasive jet is difficult to accelerate fully, and the jet is easy to inhale air, resultin...
