Abstract

The invention relates to a foaming agent stability detection device and a fading barrel. The fading barrel comprises a barrel body and a screening assembly; the barrel body is provided with an accommodating cavity, and a feed port and a liquid outlet which are communicated with the accommodating cavity; the screening assembly is arranged in the accommodating cavity and arranged between the feed port and the liquid outlet; the screening assembly comprises at least two oppositely-arranged screening pieces, and the screening pieces are provided with screening holes used for screening foam. The screening assembly comprises at least two screening pieces which are oppositely arranged; each screening piece is provided with screening holes used for screening foam, and therefore, foam can be prevented from penetrating through the screening pieces and being mixed in precipitation liquid to flow out as much as possible. It is guaranteed that all the foam flowing out of the liquid outlet are the precipitation liquid. The quality of the precipitation liquid can be accurately measured, the half-life period of the foam can be accurately detected, and then the stability of the foaming agent can beaccurately and reliably detected.

Description

technical field [0001] The invention relates to the technical field of foam agent detection, in particular to a foam agent stability detection device and a decay barrel. Background technique [0002] With the continuous acceleration of the urbanization process, the construction of subways using the shield tunneling method has become increasingly common. During the shield tunneling process, it is necessary to improve the shield dregs, and the most commonly used shield dregs modifier is foam agent. When in use, it is necessary to fully stir and mix the shield dregs generated by the cutting of the cutter head with the foam agent, so the stability of the foam agent is very critical. If the stability of the foaming agent is not good, it is very easy to cause the shield muck to fail to reach the "flow plastic" state, which will cause problems such as mud cake and gushing in the shield muck, which will affect the normal progress of shield tunneling. In order to test the stability...
