The application relates to a laboratory ventilation system, which includes a fixed frame. The opposite sides of the fixed frame are fixed with internal air ducts arranged on the same axis. The upper side of the fixed frame is fixed symmetrically with the vertical central axis of the fixed frame Two vertically arranged outer air ducts are connected, and a cylindrical movable frame whose axis line is in the same line as the vertical central axis of the fixed frame is arranged in the fixed frame. For the blower connected to the inner air pipe, the side of the movable frame corresponding to the other inner air pipe is fixedly connected with the exhaust fan connected with the air outlet and the outer air pipe. An external air pipe is connected, and the movable frame is rotatably connected to the fixed frame with the vertical center line of the fixed frame as the axis, and the fixed frame is provided with a driving mechanism capable of driving the movable frame to rotate. The application has the effect of realizing the adjustable direction of ventilation and exhaust in the laboratory, and meeting the ventilation cycle requirements of the experiment.
Description
technical field [0001] The present application relates to the field of laboratory equipment, in particular to a laboratory ventilation system. Background technique [0002] The experimental ventilation system is widely used in a series of research places such as hospitals, schools, various research institutes, etc. In the laboratory, due to the use of various chemical substances, the air pollution of the laboratory is often caused, and some substances not only smell bad In order to create a healthy and safe working environment, the laboratory ventilation system can meet the requirements of hospitals and schools to meet the above requirements. [0003] The existing laboratory ventilation system realizes rapid replacement of the gas in the laboratory through quantitative air supply and exhaust, but in the existing laboratory ventilation system, once the exhaust and supply pipelines are constructed, The direction of air supply and exhaust cannot be changed, and it is difficult...
