Intelligent diagnosis spray gun

Abstract

The invention provides an intelligent diagnosis spray gun. The intelligent diagnosis spray gun comprises a central pipe, a gun head and a data processing unit, a central channel is formed in the central pipe, a first channel is formed in the gun head along the axis of the gun head, the central channel and the first channel communicate with each other and form an inner layer channel, an inner channel microsensor is arranged in the inner layer channel, and the data processing unit is used for receiving a detection result of the inner channel microsensor and detecting and pre-judging the working state of the intelligent diagnosis spray gun according to the detection result. According to the intelligent diagnosis spray gun, the sensor is implanted in the spray gun, so that the working state and the burning loss condition of the spray gun are monitored in real time, in addition, a flow and heat transfer model is established based on the parameters acquired by the sensor, so that the working state of a spray gun body and the working state of a kiln device are intelligently diagnosed and accurately pre-judged, the planned replacement of the spray gun and the planned maintenance of the kiln device can be facilitated, the operation rate is increased, and the safety risk of equipment and operators is reduced.

Description

technical field [0001] The invention relates to the field of metal smelting equipment, in particular to an intelligent diagnostic spray gun. Background technique [0002] Melting pool smelting technology is widely used in the field of metal smelting, in which the spray gun is the core component of the metallurgical process. Media such as compressed air, oxygen, oxygen-enriched air, fuel or reducing agent form a high-speed jet through the spray gun and spray into the molten pool in the furnace, transport the medium and quickly stir the molten pool to accelerate heat transfer, mass transfer and chemical reaction process. [0003] The current spray gun only has flow, pressure and temperature measuring points in the air source valve station area, and there is no temperature and pressure monitoring means in the spray gun body and the medium channel inside the gun body, and the gun body temperature, medium temperature and medium pressure at the outlet of the spray gun cannot be ob...

AI Technical Summary

Problems solved by technology

[0003] The current spray gun only has flow, pressure and temperature measuring points in the air source valve station area, and there is no temperature and pressure monitoring means in the spray gun body and the medium channel inside the gun body, and the gun body temperature, medium temperature and medium pressure at the outlet of the spray gun cannot be obtained and other data; it is impossible to accurately calculate the flow rate of the medium when the spray gun exit enters the molten pool, and it is also impossible to judge the burnout and working status of the spray gun at the vulnerable parts of the spray gun such as the exit, and it is impossible to establish a flow and heat transfer model for the spray gun and the spray gun Diagnose the operating status of outer wall refractories or water jackets
