Technical Field

[0001] The utility model relates to the technical field of liquefied gas filling equipment, in particular to a liquefied gas mixture filling device. Background Technique

[0002] Liquefied mixture gas is a flammable liquid and is the main domestic fuel used in people's daily lives. After the liquefied mixture gas in the tank is used up, it will be uniformly recycled and refilled. During the refilling process, the liquefied gas storage facilities are transmitted to each proportioning cabinet through a pipeline system, and the operator adjusts the proportion and filling of the liquefied mixture gas through the proportioning cabinet. The common way to judge whether it is full is generally to weigh on a weighing platform, and the process must be carried out strictly in accordance with the requirements of the process regulations, otherwise there will be certain potential safety hazards.

[0003] At present, the existing liquefied mixture gas filling equipment basically does not have an additional physical protection structure for the gas filling tank. Generally, the tank is exposed during gas filling, which poses a certain safety threat to the operator invisibly.

[0004] In order to solve the above problems, we made improvements and proposed a liquefied gas mixture filling device. Content of the Utility Model

[0009] As a preferred technical solution of the utility model, a weighing groove is opened on the bottom surface in front of the left side of the proportioning cabinet. Both the weighing platform and the weighing groove are circular, and the outer diameter of the weighing platform is smaller than the inner diameter of the weighing groove. The weighing platform is electrically connected to the proportioning cabinet through a connecting wire.

[0010] As a preferred technical solution of the present utility model, an annular guide rail is fixedly installed by bolts at the bottom edge inside the weighing tank. The annular guide rail is in the shape of an arc of °. The protective bin is a cylinder. An operation opening is provided on the front surface of the protective bin, and the top view section of the protective bin is also in the shape of an arc, with an angle less than ° but greater than °.

[0011] As a preferred technical solution of the present utility model, a groove is provided at the bottom surface of the protective bin. Inside the groove, rollers are fixedly installed at equal intervals by bolts. The bottoms of the rollers are all in contact with the inner bottom surface of the track groove of the annular guide rail.
