The utility model discloses a floating type fish culture bucket which comprises a plurality of culture buckets and an annular air bag, the culture buckets are connected through a floating type passageway, an oxygen exposure disc is arranged in each culture bucket, and the top of each oxygen exposure disc is connected with a first air pump arranged on the surface of a pond through an oxygen exposure pipe. The multiple annular air bags are arranged on the outer surfaces of the multiple culture barrels in a sleeving mode respectively, the annular air bags are inflated by controlling the second air pump, the annular air bags expand rapidly to generate strong buoyancy, the culture barrels are driven to ascend stably, the culture barrels are lifted to the high position of the water surface of the pond under the action of the annular air bags, and the water surface of the pond is raised. While the culture barrel is lifted, the fishing net in the culture barrel is pulled to ascend along with the culture barrel, and the fishes can be gradually gathered and lifted along with the ascending of the fishing net, so that the culture personnel can conveniently and easily fish out the fishes in the bottom of the culture barrel, the fishing time is greatly shortened, and the fishing efficiency is remarkably improved.

The invention discloses an excrement sample collection and preservation device. A containing cavity is formed in a shell; a sampling spoon groove and a gas storage cavity are formed in the sampling body, the sampling body is connected with the shell and seals the containing cavity, and the sampling spoon groove is formed in the containing cavity; the air bag is arranged in the air storage cavity and is pre-filled with anaerobic gas; the operation part is matched with the sampling body and seals the air storage cavity, and the operation part moves relative to the sampling body and acts on the air bag to damage the air bag; the one-way ventilation structure is configured to allow anaerobic gas released by the air bag to flow into the accommodating cavity in a one-way manner and allow the gas to be discharged from the accommodating cavity to the atmosphere in a one-way manner. External anaerobic equipment is not needed, through the pre-inflation bag and the one-way ventilation structure, air replacement of the containing cavity can be completed on site after sampling, and the problem of oxygen exposure in the anaerobic bacteria transfer process is fundamentally solved.

The utility model discloses a small-sized associated gas wet desulphurization device which comprises an absorption tower, a liquid separation bag and a precipitator, an associated gas inlet is arranged at the lateral lower part of the absorption tower, a solution inlet is arranged at the lateral upper part of the absorption tower, a purified gas outlet is arranged at the top of the absorption tower, and the purified gas outlet is connected to a gas inlet of the liquid separation bag; a liquid phase outlet is formed in the bottom of the absorption tower and connected to a liquid inlet of the precipitator, a gas outlet in the top of the liquid separation bag is connected to a downstream natural gas pipeline, a liquid outlet in the bottom of the liquid separation bag is connected to the liquid inlet of the precipitator, a filtering system is arranged outside the precipitator, and an oxygen exposure device is arranged inside the precipitator. A barren liquor outlet of the precipitator is connected to a solution inlet of the absorption tower. On the premise of thoroughly changing the production mode of the original dry-type desulfurization tower, the operation risk of safe operation is reduced, the corrosion to a gathering and transportation pipe network is reduced, the production and operation cost is effectively reduced, and the safe and environment-friendly operation of oil and gas field production is ensured.

The present application relates to sewage purification technical field, specifically disclose a kind of microporous uniform gas distribution sewage aerobic aeration purification device, including main aeration frame, the both sides of being located in purification pond are erected with main aeration frame, and several sub-aeration pipes are equipped between two main aeration frames, the both ends of sub-aeration pipe are threadedly connected with connecting sleeve, and the opposite side of two main aeration frames is integrally formed with several gas guide interfaces.Through threadedly connecting between sub-aeration pipe and main aeration frame, and cooperating with the setting closed cover, the laying density of aeration pipe can be flexibly adjusted according to actual processing requirement, the modular expansion or capacity reduction is realized;Aeration assembly and sub-aeration pipe adopt plug-in type hanging structure, cooperate with the automatic on-off design of internal gas circuit, so that when replacing aeration block, water tank does not need to be emptied, only simple plug-in operation can be completed, effectively reduce maintenance difficulty and downtime, ensure the continuous and stable operation of sewage treatment device.

A method and apparatus for a two-piece capsule configured to expel air and reduce bubbles within a composition. The invention features a capsule with a cap and body, where the cap includes an insert with a dome shape designed to compress against the meniscus of a fluid composition or powder. This compression minimizes trapped air and enhances the capsule's structural integrity and longevity. Additionally, the capsule may employ a sealing element to prevent leakage, ensuring a stable, bubble-free environment for the contents. The capsule's design allows for efficient filling and reduces oxygen exposure, thus preserving the quality of the encapsulated material. The invention can be used for both powder and liquid encapsulations, enhancing shelf life and stability by significantly reducing internal air and maximizing fill volume.
