Welding smoke dust removal project of a new energy vehicle enterprise

Welding, as a key processing technology in the manufacturing industry, is widely used in automobile production, shipbuilding and construction engineering and other fields. Welding fume is mainly composed of the welding rod, welding wire and its coating material, the welding metal and its surface treatment layer in the action of high temperature volatilization, oxidation and condensation, the release of a large number of smoke in this process poses a serious threat to the health of workers.

Project Background

The welding workshop of a production base of a leading domestic new energy automobile enterprise involves multiple arc welding workstations, which need to carry out systematic management of smoke and dust, including the overall design, manufacturing, installation and commissioning, after-sales service of smoke and dust purification equipment and corresponding supporting products. Through the investigation of the user's on-site working conditions, Zhaohe has customized a personalized smoke capture and treatment solution for the user to meet the user's requirements.

Mega and Solution

Aiming at the welding fume produced by arc welding robot in the welding workshop, the arc welding room is designed to seal and trap the welding fume. Welding fume is captured into the dust removal system pipeline under the negative pressure generated by the exhaust system. Larger sparks are blocked by the spark interception device. After entering the dust collector body, the welding fume is filtered by the high-precision filter cartridge. When the amount of dust adsorbed on the surface of the filter cartridge reaches the blow-back value set by the system, the system automatically blows back, and the falling dust enters the dust accumulation barrel. The upper end of the dust accumulation barrel adopts "Zhong" baffle sparks to ensure safety. The welding fume shall be discharged to the outdoor after being purified. After treatment, the smoke concentration in the working area shall meet the occupational health operation requirements of the welding plant.

Core equipment--Mega and modular dust removal integrated machine

Mega andCFMThe series dust removal integrated machine adopts modular design, which is convenient and flexible; it is the first choice for smoke control in robot welding applications. Fit with front fixed dust collecting cover/Mobile dust collection cover and piping system is the ideal choice for single-station welding fume treatment.

1. Mega andCFMThe structural design of the series of dust removal integrated machine focuses on the separation and safety performance of smoke and dust particles, and adopts modular design to further improve the production cycle, standard degree, secondary expansion and safety performance of the equipment.

2. The product adopts imported nano flame retardant filter material, which has the characteristics of flame retardant and high filtration accuracy, lower running resistance, and can maintain extremely high air flow for a long time.0.3μm) filtration efficiency up99.9%Above. The product is equipped with pulse automatic cleaning system, at the same time integrated spark arrestor, muffler. The product covers an area of small, easy installation, stable operation.

3. Selection of fanECExternal rotor motor, can realize the motor bearing maintenance-free;ECMotor energy efficiency advantage is higherIE4, The speed range is wide, and the efficiency is relatively constant under various output powers.91%-95%; Guaranteed operation noise ≤75db.

4.Setting of electronic control systemFboxThe function can transmit the data of the smoke purifier to the remote cloud data center to realize the functions of remote data monitoring, equipment diagnosis, program maintenance and fault alarm.

system advantage

The welding fume dust removal system has the advantages of efficient purification of welding fume, small footprint, low noise, beautiful appearance and low energy consumption. Through the tailor-made arc-proof welding station building for the welding robot production line, the welding production line is cleaner and the air volume is optimized to meet the needs of smoke and dust purification and treatment of the welding production line.

This project adoptsCFME6VLThe series of integrated smoke and dust purification technology effectively solves the problem of controlling the welding smoke and dust of automobile components, and effectively reduces the investment of environmental protection funds and operating energy consumption for users.
