Abstract
The utility model discloses a low-temperature liquid filling system which comprises a low-temperature liquid storage tank provided with a low-temperature liquid outlet; one end of the low-temperature liquid outlet is connected with a low-temperature frequency-conversion pump and a damper through a liquid outlet pipeline and then communicated with liquid phase ends of a plurality of low-temperature liquid containers arranged side by side; gas phase ends are further arranged on the low-temperature liquid containers and are connected to a return air inlet of the low-temperature liquid storage tank through a return air pipeline; the low-temperature frequency-conversion pump is controlled automatically through a control system; and a weighing device is arranged below the low-temperature liquid containers and are connected with electromagnetic valves which control the on and off of filling. Compared with a former filling system, the raw material consumption during filling is greatly reduced, and environment pollution caused by that the discharge capacity is too large during filling is avoided; and the low-temperature liquid filling system has the advantages that accurate filling is realized by controlling the filling pressure and flow rate automatically and through a metering system, less operators are required, filling can be performed on a large scale, and the filling efficiency is improved.
