Description

Technical Field

[0001] This utility model relates to the field of industrial environmental management and occupational health protection technology, and in particular to an integrated welding fume purification and on-site cooling control system. Background Technology

[0002] In industrial sectors such as container manufacturing, heavy machinery production, and shipbuilding, welding is a core process for ensuring product structural strength, with wide applications and indispensable nature. However, welding operations face two major technical challenges that severely restrict improvements in production efficiency and the occupational health of employees: Firstly, the welding process generates a large amount of harmful fumes, mainly composed of metal oxides, fluorides, and nitrogen oxides, with particle diameters mostly concentrated in the range of 0.1-10μm. PM2.5 accounts for over 80% of these fumes, which easily enter the lungs through respiration. Long-term exposure can lead to occupational diseases such as pneumoconiosis and metal fume fever. Currently, the workshop-wide ventilation and dust removal systems commonly used in the industry have the following drawbacks: they require airflow circulation throughout the entire workshop space, resulting in high fan power requirements and energy consumption 3-5 times higher than single-station treatment methods; due to the obstruction caused by the workshop building structure and equipment layout, airflow forms "vortex dead zones" in the breathing area of ​​the welding station, resulting in dust removal efficiency of less than 60%, which cannot effectively protect the respiratory health of employees; and the system's ductwork is complex, leading to high maintenance costs and difficulty in adapting to the flexible adjustment needs of the production line.

[0003] Secondly, the welding arc releases a large amount of heat, with the center temperature reaching 6000-8000℃. Furthermore, most welding workshops are designed as large open spaces to meet production demands, resulting in poor air circulation in summer. This leads to temperatures in welding areas generally exceeding 35℃, and even reaching over 40℃ in some hot seasons. Existing solutions include installing air conditioning at individual workstations, which can achieve localized cooling, but air conditioning is energy-intensive, and the cooling energy easily diffuses into non-working areas, resulting in an energy utilization rate of less than 40%. Using fans for cooling disrupts the diffusion path of welding fumes, causing them to spread widely throughout the workshop, exacerbating pollution and worsening the working environment.

[0004] While existing technologies include stand-alone mobile welding fume purifiers that capture fumes through close-range suction arms, their coverage is limited to a single welding point. When multiple welding stations exist in the same workshop, multiple units are required, significantly increasing equipment purchase and operating costs, and failing to address the challenges of high-temperature environments. Furthermore, existing dust removal and cooling systems often operate independently, lacking a coordinated control mechanism. For example, when cooling fans activate, they can disrupt the negative pressure field of the dust removal system, leading to decreased fume capture efficiency and preventing the formation of an integrated "fume purification - temperature control" solution. Therefore, the industry urgently needs a highly integrated, low-energy-consumption technology that can achieve coordinated fume control and environmental regulation from the source to address the aforementioned technical pain points in traditional welding workshops.

[0016] The advantages of this utility model are: 1) This utility model organically integrates functional modules such as processing room, dust removal, cooling, and intelligent monitoring. Each module adopts a standardized interface design, and the working units and functional modules can be flexibly added or removed according to the number of welding stations and layout requirements of the production line, realizing "plug and play" and adapting to application scenarios of welding workshops of different sizes. A large-scale negative pressure field is formed in the operating area of ​​the welding station.

[0017] 2) This utility model abandons the traditional overall workshop cooling mode and adopts a modular evaporative refrigeration cycle (physical phase change). Through directional air supply ducts and adjustable air outlets, it cools only the welding work area. The cooling capacity is concentrated on the personnel operation area, and the energy utilization rate is increased to more than 75%. Compared with the evaporative cooling air conditioning unit cooling method, the energy consumption is reduced by 20%-30%. At the same time, the cooling system is linked with the Internet of Things intelligent system, which automatically adjusts the opening of the air valve and the air supply speed according to the temperature change, further reducing ineffective energy consumption.

[0018] 3) This utility model constructs a closed-loop management system based on Internet of Things (IoT) technology, encompassing "sensing-transmission-analysis-control," to achieve real-time monitoring of environmental parameters, remote monitoring of equipment operating status, and collaborative control of multiple systems. For example, it automatically increases fan airflow when dust concentration exceeds the standard, issues a replacement reminder when the filter is clogged, and automatically enters energy-saving mode when no one is operating. This not only reduces manual management costs but also optimizes equipment operating parameters through data-driven management, extends equipment lifespan, and provides data support for the construction of digital workshops.

[0019] 4) This utility model fundamentally solves the problems of smoke and dust pollution and high temperature in welding positions. After actual application testing, the PM2.5 concentration in welding positions is stably controlled below 50μg / m³, and the cooling temperature of the welding positions is controlled in the range of 20-28℃.
