Design Principles:

Utilize reliable production technologies and equipment, along with modern management, to replace traditional, outdated painting processes, equipment, and management. Meet requirements for painting processes, paint quality, environment, hygiene, and production schedules; equipment is reliable, advanced, aesthetically pleasing, operates economically, is easy to operate, and user-friendly.

Painting workshop layout principles:

Manual and non-manual operation areas are relatively separated.

2. Clean and non-clean areas are separated relative to each other.

Minimize the volume of transportation.

4. Minimize noise pollution.

Process Design:

Based on the absorption and digestion of advanced technology and mature experience in domestic and international painting, ensure that this process design is practical, reliable, and advanced.

All equipment design and manufacturing strictly comply with national standards regarding environmental protection, hygiene, and safety. Noise reduction measures are implemented on all equipment, ensuring noise levels in the workshop are kept below 85 decibels.

The equipment meets the product's usage requirements, operates reliably, is easy to operate, and convenient for maintenance and upkeep.

The selected accessories, materials, and electrical components are all domestic renowned products, ensuring reliable quality and performance, as well as the service life of the equipment.

Thoroughly consider the interconnectivity between systems and implement protective measures for equipment failures to prevent accidents.

Equipment Description and Structural Design

1. Working Principle:

During painting, the external air is filtered through the primary filter mesh at the intake vent and then distributed to the roof by the fan (heating system is activated in winter). This allows the gas to enter the static pressure room, uniformly filling the paint room and forming an air curtain around the workpiece. At this point, the air speed in the paint room is above 0.23m/s, ensuring that paint mist during painting does not linger in the operator's breathing zone but quickly descends. Subsequently, the air flow is directed through the exhaust fan to the exhaust duct, passing through the waste gas treatment system and being released via the environmental protection box, thereby ensuring the discharged gas meets the GB16297-1996 standard.

2. Main structure and components of the equipment

Structure Composition: Comprising the room body, lighting system, air filtration system, air distribution system, heating system, exhaust system, paint mist and waste gas treatment system, electrical control system, and safety system, among others.

2.1. Enclosure: Composed mainly of the frame, wall panels, workpiece access doors, and safety doors. The enclosure meets the national or relevant industry standards for strength, stability, thermal insulation, sealing, impact resistance, and seismic resistance.

⑴ Skeleton

The housing frame is made by bending and welding square steel tubes and galvanized steel plates.

⑵ Wall Panels

The room panels are made of composite thermal insulation boards, with both inner and outer panels being color steel plates, filled with 58mm thick insulation material. Total thickness is 75mm. All panels are assembled in a modular structure for easy installation and disassembly. The color is white.

Lighting System: Explosion-proof lighting units are installed at the top and side sections of the room. The top section lights are mounted at a 45-degree angle, while the side section lights are installed within the wall panels. The tubes utilize explosion-proof Philips high-efficiency sources, ensuring safety, energy-saving, and easy maintenance. The ballasts are designed by our company specifically for spray rooms, guaranteeing an illumination intensity of approximately 700 Lux.

Each side of the waist is equipped with two layers of lighting arrangement.

2.3 Air Filtration System

Air filtration is a two-stage process, including preliminary filtration (inlet air filtration) and high-efficiency filtration (top filtration). The preliminary filtration is set at the inlet, featuring a mesh structure, which effectively filters particles larger than 15μm.
