Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a sealed soft bag. Background Art

[0002] In some occasions, such as in medical processes, some polluted gas-liquid mixtures are produced. The waste gas in these gas-liquid mixtures has the characteristics of high pressure, high toxicity and harmfulness. The gas in the gas-liquid mixture cannot be discharged directly, and the liquid cannot be discharged directly into the external environment, so it needs to be recovered. The prior art does not have a device that can easily separate the gas-liquid mixture. Generally, the gas-liquid mixture is directly recovered together. In the case of large quantities, it causes problems such as great difficulty in recovery and high recovery cost. Summary of the invention

[0003] The purpose of the present invention is to provide a sealed soft bag for filtering highly toxic and harmful polluted liquids to solve the above technical problems.

[0006] At least one liquid inlet channel is provided on the lower inner wall of the annular ball rack, the liquid inlet channel is located between the upper limit ring and the lower limit support and outside the ball, and the liquid inlet channel is connected to the inside and outside of the soft bag;

[0007] An elastic reset mechanism is provided in the soft bag, and a piston rod of the elastic reset mechanism is located below the ball. When the elastic reset mechanism is in a reset state, the piston rod presses against the ball above, and the ball blocks the liquid inlet channel.

[0008] The soft bag is provided with a soft bag through hole connecting the inside and outside of the soft bag, an activated carbon frame is provided inside the soft bag through hole, and a block of activated carbon is provided in the activated carbon frame. The block of activated carbon faces the soft bag through hole and blocks the soft bag through hole.

[0009] When the present invention is used, the catheter is inserted into the bag mouth, one end of the catheter extends into the annular ball frame of the bag mouth, and the other end of the catheter is connected to the contaminated gas-liquid mixture, and the gas-liquid mixture is introduced through the catheter. During the introduction, due to the effect of the gas-liquid mixture, the ball is pushed downward, and then the piston rod of the elastic reset mechanism is pushed downward, the piston rod leaves the ball, the ball falls on the lower limit support, the ball makes way for the liquid inlet channel, and the gas-liquid mixture enters the soft bag from the liquid inlet channel. After the gas-liquid mixture is introduced, the catheter is pulled out, and due to the reset effect of the elastic reset mechanism, the piston rod supports the ball, the ball blocks the liquid inlet channel, and the gas-liquid mixture does not flow out of the bag mouth. Due to the setting of the block activated carbon, the gas in the gas-liquid mixture can be filtered into clean gas by the block activated carbon and released into the external environment, leaving only the contaminated liquid in the soft bag, achieving the purpose of only liquid recovery, and the whole recovery process is simple and easy, low cost, and low recovery difficulty.

The protrusion arrangement can further ensure that the block activated carbon is firmly fixed in the activated carbon frame for filtering gas.

[0019] The soft bag is a self-supporting bag with a horizontal support structure at the bottom, so that the soft bag can stand on its own. This soft bag can be used to recover a large volume of gas-liquid mixture.

[0020] The soft bag may also be a flat structure with a self-sealed bottom and no horizontal support structure at the bottom, and is used to recover a smaller volume of gas-liquid mixture.

The ball 3 is preferably made of metal or glass.

[0036] Reference Figure 3, an elastic reset mechanism is provided in the soft bag, and the piston rod 41 of the elastic reset mechanism is located below the ball 3. When the elastic reset mechanism is in the reset state, the piston rod 41 presses against the ball 3 above, and the ball 3 blocks the liquid inlet channel 23. The elastic reset mechanism includes a mechanism frame 42 connected to the bag mouth, a bottom bracket 43 arranged in the mechanism frame 42, a guide rod 44 arranged in the bottom bracket 43, a spring 45 arranged at the lower part of the guide rod 44, a piston bracket 46 arranged at the upper part of the guide rod 44, and a piston rod 41 arranged on the piston bracket 46.

So that the piston rod 41 can be inserted into the lower limit bracket 22 of the annular ball frame to press against the ball 3.

[0037] The bag mouth 11 and the mechanism frame 42 are preferably made of PP or PE materials, and the mechanism frame 42 is made integrally with the bag mouth 11. The mechanism frame 42 extends downward into the interior of the soft bag 1, and a buckle position is provided on the inner side of the mechanism frame 42, and a buckle position is also provided on the outer side of the bottom bracket 43, and the mechanism frame 42 and the bottom bracket 43 are fixed by the buckle position.

The piston rod 41 leaves the ball 3, and the ball 3 falls on the lower limit support 22. The ball makes way for the liquid inlet channel 23, and the gas-liquid mixture enters the soft bag 1 from the liquid inlet channel 23. Figure 5 When the gas-liquid mixture is introduced, the conduit 7 is pulled out. Due to the reset effect of the elastic reset mechanism, the piston rod 41 presses against the ball 3, and the ball 3 blocks the liquid inlet channel 23, so that the gas-liquid mixture will not flow out of the bag mouth. Due to the setting of the block activated carbon 6, the gas in the gas-liquid mixture can be filtered into clean gas by the block activated carbon 6 and released into the external environment. Only the contaminated liquid is left in the soft bag 1, achieving the purpose of only recovering the liquid. The whole recovery process is simple and easy, low cost, and low recovery difficulty.
