Description

Technical Field

[0001] The utility model relates to the technical field of vehicle spray painting, in particular to a novel wind speed acceleration device for a paint room. Background Art

[0002] China's national VOC emission regulations are becoming increasingly stringent. Water-based paint is now widely used in automotive painting. The heating and curing process for water-based paint requires that at least 90% of the water in the paint evaporate to achieve the best possible paint film appearance. Increasing air flow can accelerate water evaporation, but the air from existing paint booth wind speed accelerators cannot reach very far, which can be problematic for paint-baking areas on buses, for example. Furthermore, the two commonly used water-based paint accelerators in the market use simple filtration and nozzle-discharged air, resulting in extremely uneven air speeds within the booth, which can lead to a high incidence of dust spots on the dried paint surface. Furthermore, the filter element is difficult to remove and replace, making it inconvenient to use. Utility Model Content

[0003] The purpose of the present utility model is to provide a new wind speed acceleration device for a paint room to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a new wind speed acceleration device for a paint room, comprising a room body, a duct shell provided at the bottom of the room body, a liftable moving frame provided inside the room body, a filter cotton core placed in the moving frame, and a through-hole plate fixedly connected to the bottom of the moving frame.

[0005] Optionally, a blower is provided on the left side of the room body, the top of the blower is connected to the room body through a ventilation pipe, and a damper 1 is installed on the left side of the blower.

[0006] Optionally, an exhaust fan is provided on the right side of the room, the top of the exhaust fan is connected to a vertical pipe, the top of the vertical pipe is connected to a damper 2, and the left side of the vertical pipe is connected to the room through a damper 3.

[0007] Optionally, a grille is installed in the opening at the top of the air duct shell.

[0008] Optionally, a fixed frame is fixedly connected to the inner wall of the room body, an insertion frame is fixedly connected to the top of the movable frame, and the top of the insertion frame is movably plugged into the fixed frame.
