Description

Toxic gas mixing bin Technical Field The utility model belongs to the technical field of gas preparation, and particularly relates to a toxic gas mixing bin. Background In the fields of chemical industry, scientific research and the like, a plurality of toxic gases are mixed according to a certain proportion by using a gas mixing bin. However, there are a number of problems with existing toxic gas mixing bins. For example, after the toxic gases in different batches are mixed and reacted, generated solid or liquid impurities can adhere to the inner surface of the bin body, so that impurities are easy to remain in the gas mixing bin after the gas mixing bin is used for a long time, the interior needs to be cleaned in time or regularly, if the gas mixing bin is not cleaned in time, the residual toxic gases and impurities in the interior can influence the mixing proportion of the gases to interfere the accuracy of an experiment or a production process, even the residual toxic gases and impurities can have corrosiveness, corrosion can be caused on the inner structure of the gas mixing bin, and the service life of equipment is shortened. In general, the common cleaning flow is to clean impurities on the inner wall of the bin body after pretreatment such as multiple gas replacement before cleaning, and in the cleaning process, operators need to take protective measures to directly clean the inner wall of the bin body by using cleaning tools, but frequent use of tools for deep cleaning has the problem of inconvenient cleaning. Disclosure of utility model In view of the above, the utility model provides a toxic gas mixing bin which can solve the problem of inconvenient cleaning when a tool is used for deep cleaning. The utility model is realized in the following way: The utility model provides a toxic gas mixing bin, which comprises a gas mixing bin main body, a detachable cleaning module, a quick-detachable gas access pipe and a multiple sealing structure, wherein the detachable cleaning module is arranged in the gas mixing bin main body, and the quick-detachable gas access pipe are respectively connected with the gas mixing bin main body through the multiple sealing structure.
