[0002] Currently, a large amount of liquid products are sold by tank trucks every day. Before filling the liquid tank truck, in order to ensure the safety of filling and the quality of the product, the residual liquid in the tank truck storage tank needs to be emptied.

[0003] At present, venting mainly relies on the gasification system of the tank truck's own tank to evacuate at low altitude. In the process of venting, firstly, a lot of noise is generated, which affects the surrounding working environment; secondly, low-pressure venting easily causes low-altitude gas accumulation, some of which are combustion-supporting and asphyxiating gases, which are not conducive to production and personnel operations; thirdly, since the tank truck's own gasification system is relatively small and the gasification time is long, the tank truck has a long waiting time for filling, which reduces the filling efficiency and affects the customer's medium supply.

By adopting a movable base and a silencer, the low-temperature residual liquid in the storage tank can be quickly discharged.
