Large scale automatic retractable painting room for workpieces

Large scale automatic retractable painting room for workpiecesCore Features

1. High space utilization and strong flexibility:

Telescopic moving structure: The main structure of the paint booth (usually the shed frame and covering material) can automatically expand and move according to the size of the workpiece. Expand the coverage of the workpiece for painting during work; Shrink and fold when not working to free up workshop space.

Adapt to workpieces of different sizes: Only one paint booth is needed to handle various large workpieces with significant differences in length, width, or height, without the need to build multiple fixed size paint booths.

No need for fixed foundation: usually installed on tracks, without the need for deep foundations like fixed houses, saving civil engineering costs and cycles.

2. Efficient and environmentally friendly:

Closed operation: During spraying operations, the retractable shed is closed to form a relatively enclosed space.

Paint mist treatment system: Integrated with efficient paint mist capture and filtration system (such as dry filter cotton/filter cartridge/filter box or wet water curtain/water swirl system), effectively removing paint mist particles from the air.

VOC treatment (optional): Can be connected to backend exhaust gas treatment equipment such as activated carbon adsorption, catalytic combustion, RTO, etc., to meet increasingly strict VOC emission standards.

Negative pressure design: Maintain a slight negative pressure inside the room through exhaust fans to prevent paint mist and harmful gases from escaping.

3. Improve the working environment:

Lighting system: Equipped with sufficient explosion-proof lighting fixtures to ensure sufficient and uniform lighting in the painting area.

Ventilation: After closed spraying, the ventilation system can be opened to introduce fresh air, eliminate solvent odors, improve the working environment for workers, and shorten the waiting time for workpiece drying (especially for natural drying).

Safety: Explosion proof design (electrical, fan, etc.) to reduce the risk of combustible gas accumulation.

4. Energy conservation and consumption reduction:

On demand start stop: The air supply, exhaust, and filtration system is only deployed and operated when painting is needed. When idle, it shrinks and closes, greatly saving the energy consumption of the fan operation (which is the main energy consumption of the painting room).

Reduce air conditioning/heating load: Compared to the overall temperature regulation of workshops with large spaces, it is more energy-efficient to adjust the temperature of relatively small enclosed paint spaces (if necessary).

5. Automation and Intelligence:

Automatic control: The core is the PLC control system, which realizes centralized control and linkage of functions such as automatic expansion and contraction of the shed, start and stop of the fan, lighting switch, alarm, etc.

Safety protection: usually equipped with safety devices such as travel limit, collision detection, emergency stop, etc.

Remote monitoring (optional): It can achieve remote viewing and management of operating status and fault alarms.

Large scale automatic retractable painting room for workpiecesTypical application scenarios

• Wind power industry: The painting (primer, topcoat, leading edge protection) of wind turbine blades (up to 80 meters in length) is its most typical and largest application market.

• Ship and Ocean Engineering: Painting of Ship Segments and Superstructure Modules.

• Construction machinery: large complete machines or large structural components such as excavators, cranes, loaders, etc.

• Rail transit: locomotives, carriages, bogies.

• Large steel structures: bridge components, building steel structures, tower tubes.

• Aerospace: Large components (such as wing segments).

• Large pipelines and containers.

Summary of Advantages

• Space saving: Especially suitable for workshops with limited space or requiring flexible layout.

• Flexible investment: Compared to building multiple fixed large houses, the initial investment may be better and can be moved and reused.

• Energy saving operation: significantly reduces fan energy consumption and workshop temperature control costs.

• Environmental compliance: Effectively collect and process paint mist and VOCs to meet regulatory requirements.

• Improve efficiency: Flexibly adapt to different workpieces, reduce waiting and turnover time.

• Improving the environment: providing better working conditions for workers.

Choose factors to consider

• Maximum/minimum workpiece size: determines the design size and stroke of the expansion room.

• Workpiece type and spraying process: affect the selection of paint mist treatment method, VOC treatment level, and explosion-proof requirements.

• Environmental regulations require, especially VOC emission standards and paint mist treatment efficiency requirements.

• Workshop conditions: available space, height, ground load-bearing capacity, power supply, compressed air, etc.

• Budget: Prices vary greatly depending on different configurations (materials, filtering methods, degree of automation, brand).

• Supplier qualifications and experience: Choose suppliers with rich cases and reliable after-sales service in the field of large workpieces.
