Abrasive water jet (AWJ) cleaning and derusting equipment capable of adjusting mixed slurry concentration

Abstract

The invention discloses abrasive water jet (AWJ) cleaning and derusting equipment capable of adjusting mixed slurry concentration. The AWJ cleaning and derusting equipment is characterized by comprising a mixed slurry four-way valve, an abrasive hopper for holding water and an abrasive and a variable frequency motor; in the mixed slurry four-way valve, an upward pipe orifice is communicated with a communicating pipe, a downward pipe orifice is equipped with an end cap, a left pipe orifice is communicated with an outlet pipe of a spiral conveyor, and a right pipe orifice is communicated with an inlet pipe of a high-pressure diaphragm pump through a low-pressure hose; the spiral conveyor is arranged at the bottom of the abrasive hopper, the abrasive hopper is internally equipped with a screen capable of horizontally moving back and forth, and the screen is submerged in water in the abrasive hopper so as to realize wet screening; and the variable frequency motor can control delivery quantity of the abrasive of the spiral conveyor. The AWJ cleaning and derusting equipment can operate continuously and circularly and can realize recovery and reuse of the abrasive, and can be widely applied to cleaning, derusting and other fields.

Description

technical field [0001] The invention relates to a water jet cleaning and derusting equipment, more specifically an abrasive water jet cleaning and derusting equipment. Background technique [0002] At present, it is more common to use abrasive water jet technology for cleaning and derusting operations in the market. However, when the pre-mixed abrasive water jet technology is used for cleaning and derusting operations, the continuous operation time is limited by the volume of the high-pressure abrasive tank in the system; although the volume of the abrasive tank is large, the operating time is long, but the time for injecting abrasives into the abrasive tank is also limited. It is long, so the operation cannot be carried out continuously, which brings inconvenience to the user. If the post-mixing is used, that is, the ejection abrasive jet, the acceleration time of the abrasive particles is short and the abrasive and high-pressure water cannot be uniformly mixed, so the pre...

Problems solved by technology

However, when the pre-mixed abrasive water jet technology is used for cleaning and derusting operations, the continuous operation time is limited by the volume of the high-pressure abrasive tank in the system; although the volume of the abrasive tank is large, the operating time is long, but the time for injecting abrasives into the abrasive tank is also limited. Long, so it can't work continuously, which brings inconvenience to users

If the post-mixing is used, that is, the ejection abrasive jet, the acceleration time of the abrasive particles is short and the abrasive and high-pressure water cannot be uniformly mixed, so the pressure required for work is relatively high.

In addition, high-pressure water pumps are used as the power source of the system in the prior art, and it is difficult to adjust the abrasive concentration in the jet flow, and there is no special abrasive recovery and reuse system
