Laboratory integrated experimental fume hood

Abstract

The invention discloses a laboratory integrated experimental fume hood, which comprises a circulating air supply fume hood. A negative pressure experiment operation cavity is arranged inside the cycle supply air supply fume hood, and a faucet is arranged in the negative pressure experiment operation cavity. , socket; the back side of the circulating air supply fume hood is provided with a diversion air duct, the guide air duct is provided with an air outlet, and the upper side of the circulating air supply fume hood is provided with an air outlet box to communicate with the diversion air duct; It also includes a ventilation integrated joint, which communicates with the air inlet box and the air outlet box through the air inlet pipe and the air outlet pipe; The ventilation connection of the fume hood is integrated, and the integration of the water supply and electricity connection of the fume hood is realized through the external integrated joint. Once the fume hood needs to be moved or changed, it is no longer necessary to reconnect the air ducts, water pipes, wires, etc., which improves efficiency and at the same time Improved security.

Description

technical field [0001] The invention relates to the field of laboratory technology, in particular to an integrated experimental fume hood applied to laboratory work. Background technique [0002] During the experimental operation of the experimental instrument bench, when corrosive liquids are used, or toxic and harmful gases may be generated during the experiment, reliable fume hoods are needed to ensure the health and safety of the experimenters, and at the same time provide the experimenters with A stable environment is also crucial to the accuracy of experimental data. However, the air in the laboratory must be exchanged with the outside air, and there are higher requirements for the connection of ventilation ducts. At the same time, to ensure the normal progress of the experiment, the instrument also needs to be connected with supporting water and electricity devices, which has great restrictions on the fume hood, especially when it needs to be moved or changed, the re...

However, the air in the laboratory must be exchanged with the outside air, and there are higher requirements for the connection of ventilation pipes.

At the same time, to ensure the normal progress of the experiment, the instrument also needs to be connected with supporting water and electricity devices, which has great restrictions on the fume hood, especially when it needs to be moved or changed, the rearrangement of ventilation, water, and electricity is a big problem
