The invention relates to the technical field of ventilation and dust removal of vehicles, and discloses a turning plate type ventilation and dust removal device which comprises a turning plate type flow guide body and a filter screen. The direction of the air inlet, formed in the flow guide body frame, of the turnover flow guide plate of the turnover plate type ventilation and dust removal device is kept opposite to the airflow direction, the requirement that airflow needs to enter a cavity where an internal combustion engine is located when a vehicle advances in different directions can be met without reversing the direction of the turnover plate type flow guide body, and labor is saved; the waveform filter screen increases the air inlet sectional area, the air inlet sectional area can be freely adjusted according to the air inlet requirement, and the air inlet amount is ensured; the air inlet holes are formed in the protruding structures of the filter screen, impurities in airflow are prevented from entering the air inlet holes, and the filter screen can be prevented from being blocked. The sectional areas of the air inlet and the ventilation opening are both two to three times of the section of the main ventilation duct, so that the turning plate type ventilation and dust removal device is high in air speed and large in air inlet amount, meets the air inlet requirement and can achieve a good dust removal effect.

    本发明涉及交通工具换气除尘技术领域,公开了一种翻板式通风除尘装置,包括翻板式导流体和滤网;该翻板式通风除尘装置的翻转导流板在导流体框架上形成的进风口的方向保持与气流方向相反,实现了无需倒转翻板式导流体的方向即可满足交通工具按不同方向行进时需要气流进入内燃机所在腔室的要求,节约了人工;波形滤网增加了进气的截面积,而且能根据进气需要自由调节进气截面积,确保进气量;进气孔设置在滤网的凸起结构上,阻止气流中的杂质进入进气孔,可以防止滤网堵塞;进风口、通风口的截面积均为主通风道的截面的二倍至三倍,使翻板式通风除尘装置风速高、进风量大,满足进气需求外,还能达到较好的除尘效果。
