Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a fresh air exchange device for factory air purification. Background Technology

[0002] As the core location for industrial production, the air environment of a factory directly affects production efficiency, product quality, and the health and safety of workers. During industrial production, processes such as welding, grinding, and chemical reactions can easily generate pollutants such as dust, harmful gases, and odors. At the same time, heat dissipation from equipment operation can lead to increased temperature and poor air circulation inside the factory. If workers are exposed to such an environment for a long time, it will not only accelerate equipment aging and affect the precision of precision-machined products, but may also cause respiratory diseases, dizziness, fatigue, and other health problems for workers, which does not meet industrial hygiene standards and safety production regulations.

[0003] Traditional factory ventilation systems have a fixed air intake direction, making it difficult to adapt to the varying ventilation requirements of different factory layouts, equipment placements, and production processes. This results in localized ventilation dead zones, limited air intake efficiency, and the fixed installation of filter components, which makes disassembly cumbersome and requires specialized tools and personnel, increasing the difficulty and cost of cleaning and replacing filter components. Consequently, the purification effect is insufficient to meet the requirements of high-standard production environments. Therefore, it is necessary to design a new air exchange and purification system for factory air purification to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fresh air exchange device for factory air purification to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fresh air exchange device for factory air purification, including a fan, an air inlet pipe connected to one side of the fan, a rotating rod connected to the bearing at the middle of the air inlet pipe and the rotating rod extending to the outside of the air inlet pipe, two sets of fan blades fixedly connected to the outside of the rotating rod, and a fixing component installed between the top of the air inlet pipe and the rotating rod. The bottom of the fan is provided with a support plate, and three sets of support frames are arranged on the top of the support plate.

[0007] Preferably, the support assembly includes a placement slot, a placement plate, a baffle, and an L-shaped support frame. Two sets of placement slots are respectively opened at both ends of the bottom of the fan. Two sets of placement plates are respectively connected to both sides of the support plate. Two sets of baffles are respectively bearing connected to both ends of the fan. Two sets of L-shaped support frames are respectively fixedly connected to both ends of the bottom of the fan, and the baffle can slide into one of the L-shaped support frames.
