Description

Technical Field

[0001] The utility model relates to the technical field of dangerous chemical unloading, in particular to a dangerous chemical safe unloading device. Background Art

[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that have properties such as toxicity, corrosion, explosion, combustion, and combustion-supporting properties, and are harmful to the human body, facilities, and the environment.

[0003] When a vehicle carrying hazardous chemicals unloads hazardous chemicals, it is necessary to connect the outlet of the transport vehicle's storage tank to the on-site unloading port. However, the calibers of existing connecting pipes are fixed and the sizes are not uniform. Therefore, wire or tape is often used on site to connect and fix the unloading pipeline interface. This poses a risk of pipeline detachment and burns caused by hazardous chemicals. This operation also prevents the two interfaces from being connected efficiently and safely during the unloading process. At the same time, the accumulated liquid in the pipeline is not cleaned up in time after unloading, resulting in serious corrosion of equipment and pipelines. For this reason, we propose a safe unloading equipment for hazardous chemicals based on the actual production site. Utility Model Content
