Integrated soft bag for filtering high-toxicity harmful pollution liquid

Abstract

The invention relates to the technical field of packaging, in particular to a sealed soft bag. The integrated soft bag for filtering high-toxicity harmful pollution liquid comprises a soft bag body, abag mouth and a bag cover, wherein an annular ball frame is arranged in the upper portion of the bag mouth, an upper limiting ring and a lower limiting support are arranged on the lower portion of the annular ball frame, balls are arranged between the upper limiting ring and the lower limiting support, and the balls seal the bottom of the annular ball frame; at least one liquid inlet channel is arranged on the inner wall of the lower part of the annular ball frame and communicates with the inside and the outside of the soft bag body; an elastic reset mechanism is arranged in the soft bag body, a piston rod of the elastic reset mechanism is located below the balls, when the elastic reset mechanism is in a reset state, the piston rod abuts against the balls above, and the balls block the liquid inlet channel; and an accommodating groove is dug in the lower part of the bag mouth, and the accommodating groove communicates with the inside and the outside of the soft bag body and is filledwith blocky activated carbon. According to the technical scheme, when the sealed soft bag is used for recovering the gas-liquid mixture, the recovery is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a sealed soft bag. Background technique [0002] In some occasions, such as medical processes, some polluted gas-liquid mixtures will be produced, and the waste gas in these gas-liquid mixtures has the characteristics of high pressure, high toxicity and harmfulness. Among them, the gas in the gas-liquid mixture cannot be discharged directly, and the liquid cannot be discharged directly to the external environment, and needs to be recycled. In the prior art, there is no device that can easily separate the gas-liquid mixture. Generally, the gas-liquid mixture is directly recovered together. In the case of a large amount, the recovery is difficult and the recovery cost is high. Contents of the invention [0003] The object of the present invention is to provide an integrated soft bag for filtering highly toxic and harmful polluted liquids, so as to solve the above technical pro...
