Automatic filling system and automatic filling method for low-temperature liquid storage tank

Abstract

The invention relates to an automatic filling system and automatic filling method for a low-temperature liquid storage tank. The low-temperature liquid storage tank is connected with a vehicle liquidfilling pump through an automatic filling inlet valve and a first connecting pipeline. The vehicle liquid filling pump is connected to a filling port through an automatic filling outlet valve and a second connecting pipe. The automatic filling inlet valve, the vehicle liquid filling pump and the automatic filling outlet valve are correspondingly connected with and controlled by a center console arranged outside, and the center console is further connected with a plurality of on-site video monitors and all instrument measuring points. The automatic filling system is controlled by the centre console through being equipped with monitoring cameras, voice intercom, lighting and other facilities on site, and the automatic filling system has the characteristics of simple structure, safety, reliability, rationality and high efficiency, reduction of labor cost, substantial improvement of labor productivity and replacement of manual operation in low-temperature dangerous environment.

Description

technical field [0001] The invention relates to an automatic filling system and an automatic filling method for a low-temperature liquid storage tank, and belongs to the technical field of low-temperature liquid storage tank filling. Background technique [0002] In the existing technology, when filling cryogenic liquid products, workers need to go to the site to cool the pump, turn on the pump, and have workers to take care of the site until the filling is completed; when encountering an area with good product sales, product tankers are frequently filled, and the factory The operating personnel are tense and inefficient, which is not conducive to the manual arrangement and normal operation of the entire factory; accidents may occur during cooling pump and filling, which poses risks to the personal safety of employees. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a simple structure, sa...
