The utility model realizes a sealed closure between the glass cover and the base under the action of the pneumatic cylinder, thereby realizing a sealed isolation of the device and preventing the leakage of harmful gases generated by the experiment.

[0004] Although the above-mentioned emergency isolation device for hazardous chemicals is sealed and closed with the base by the glass cover under the action of the pneumatic cylinder, thereby realizing the sealed isolation of the device and preventing the leakage of harmful gases generated by the experiment, when a fire occurs, the staff usually uses a fire extinguisher to put out the fire.

[0015] Preferably, the lifting hydraulic cylinder forms a telescopic structure through the linkage block and the sealing cover, and the lifting hydraulic cylinder is symmetrically distributed about the vertical center line of the isolation box.

[0016] Compared with the prior art, the utility model provides an emergency isolation device for hazardous chemicals, which has the following beneficial effects:

[0017] The utility model can connect the material baffle plate and the material storage box through the rubber block, and the flame retardant layer can prevent the fire source in the isolation box from spreading outward, so that when a fire occurs, the rubber block can be burned by the fire source, and then the material baffle plate can fall down to put out the fire, and at the same time, the fire extinguishing materials in the storage bin can flow out, and a secondary fire fighting can be carried out, thereby achieving the effect of emergency fire extinguishing, avoiding the problem that the staff usually use fire extinguishers to put out the fire when a fire occurs, and the staff need to come into close contact with the fire source due to the unclear state of the flammable liquid in the isolation device, which is easy to cause safety hazards.
