Description
技术领域technical field
本发明涉及孔隙水采集检测技术，尤其涉及孔隙水压榨器。The invention relates to a pore water collection and detection technology, in particular to a pore water squeezer.
背景技术Background technique
现有的海底沉积物孔隙水压榨采集技术中，可快速探测泥沙样品中CH4、H2S等气体和Cl-、SO4 2-等离子的异常及其分布特征，为天然气水合物和油气资源探查提供快速、高效的地球化学证据。但现有的海底沉积物采集技术主要是用重力活塞采集沉积物之后，再在实验室通过普通压榨、离心和真空过滤抽提等一些手段进行孔隙水的提取，这些方法都是在常规环境下进行的，经过长期周转，过程繁杂，不易得到真实的数据。特别是在进行离心处理或者真空过滤的过程中，会导致孔隙水中的溶解气体逃逸或者消失，因此不能准确反映孔隙水的原始成分和信息；另外，普通压榨方式存在的问题是过滤不彻底，其压榨后装置分离困难。In the existing seabed sediment pore water squeeze acquisition technology, it can quickly detect the anomalies and distribution characteristics of CH 4 , H 2 S and other gases and Cl - , SO 4 2- plasma in sediment samples, which are natural gas hydrates and oil and gas Resource exploration provides fast, efficient geochemical evidence. However, the existing seabed sediment collection technology mainly uses gravity pistons to collect sediments, and then extracts pore water in the laboratory by means of ordinary pressing, centrifugation, and vacuum filtration extraction. After a long-term turnover, the process is complicated and it is difficult to obtain real data. Especially in the process of centrifugal treatment or vacuum filtration, the dissolved gas in the pore water will escape or disappear, so the original composition and information of the pore water cannot be accurately reflected; Difficulty separating the device after pressing.

Moreover, when the topmost pressure head 11 is pressed, it will It can simultaneously drive the pressure head 11 of each pore water squeezer 10 to simultaneously squeeze the seabed sediments in the accommodation chamber 14. The force of each pore water squeezer 10 is balanced, and the water output is unified. The pore water obtained by squeezing will be collected by the external pore water collector. , making its pressing more efficient and faster, and more importantly, through the sealing and plugging cooperation of the upper pressure head 11, the base 13 and the outer cylinder 12, the sealing effect can be better, and the seabed sediment and pore water can be effectively avoided Leakage loss is also more conducive to efficient and rapid pressing, so as to achieve the effect of easy operation and reliable performance.
其中，通过另一个孔隙水压榨器10的压头11与插槽131的插装配合，可使各个孔隙水压榨器10的串接更为稳固，也更便于装拆。压榨后的孔隙水将在容纳腔14中保留，采用外部孔隙水收集器可将该孔隙水采集取用。Wherein, through the insertion fit between the pressure head 11 of the other pore water squeezer 10 and the slot 131, the serial connection of each pore water squeezer 10 can be made more stable and easier to assemble and disassemble. The squeezed pore water will be retained in the accommodation chamber 14, and the pore water can be collected and used by using an external pore water collector.
为便于出水，底座13内开有流道132，流道132的一端贯通至底座13的上端，流道132的另一端贯通至底座13的侧壁，该流道132的一端封盖有烧结毡20，流道132的另一端用于与外部孔隙水收集器连通。容纳腔14内的出水将经流道132一端流至流道132另一端，其中，所设置的烧结毡20可有效过滤海底沉积物的颗粒，同时又提供了足够的强度支撑。In order to facilitate water discharge, a flow channel 132 is opened in the base 13, one end of the flow channel 132 runs through the upper end of the base 13, and the other end of the flow channel 132 runs through the side wall of the base 13, and one end of the flow channel 132 is covered with a sintered felt 20.

The outlet water in the accommodation chamber 14 will flow from one end of the flow channel 132 to the other end of the flow channel 132 , wherein the sintered felt 20 can effectively filter the particles of seabed sediments and provide sufficient strength support at the same time.
作为优选，流道132包括多个分流通道1321及分别连通各分流通道1321的主通道1322，分流通道1321位于底座13的上端，分流通道1321的上端入口周围开有第一嵌口133，烧结毡20嵌置于第一嵌口133内，且烧结毡20的上表面与底座13的上端齐平。多个分流通道1321的设置，更利于快速排水，而且，通过第一嵌口133的设置，烧结毡20上表面与底座13的上端齐平，如此可避免烧结毡20受到过多的摩擦损耗，也可对烧结毡20更稳定的定位。Preferably, the flow channel 132 includes a plurality of distribution channels 1321 and a main channel 1322 respectively connected to each distribution channel 1321, the distribution channels 1321 are located at the upper end of the base 13, the upper end of the distribution channel 1321 is surrounded by a first socket 133, and the sintered felt 20 is embedded in the first socket 133 , and the upper surface of the sintered mat 20 is flush with the upper end of the base 13 .

为进一步加强过滤效果，本实施例的底座13的上端端面覆盖有过滤膜30，该过滤膜30与外筒12的内壁密封贴合。由于流道132的一端被烧结毡20覆盖，因此，烧结毡20可保护过滤膜30，防止过滤膜30被压头11施压而挤入流道132的一端而破损。In order to further enhance the filtering effect, the upper end surface of the base 13 in this embodiment is covered with a filter membrane 30 , and the filter membrane 30 is sealed and attached to the inner wall of the outer cylinder 12 . Since one end of the flow channel 132 is covered by the sintered felt 20 , the sintered felt 20 can protect the filter membrane 30 and prevent the filter membrane 30 from being squeezed into one end of the flow channel 132 by the pressure head 11 and damaged.

The other end of the flow channel 132 is provided with an installation port 134. The installation port 134 is used for fast and convenient installation of an external pore water collector. It can be combined with Elements such as bushings, seals, and gaskets further enhance the seal.
为更进一步提升密封效果，压头11的下端端面覆盖有密封垫40，当压头11下压容纳腔14内的海底沉积物时，该密封垫40可避免海底沉积物及其孔隙水在压头11与外筒12间的细微缝隙中漏出。In order to further improve the sealing effect, the lower end surface of the indenter 11 is covered with a sealing gasket 40. When the indenter 11 presses down on the seabed sediment in the accommodation chamber 14, the sealing gasket 40 can prevent the seabed sediment and its pore water from being compressed. It leaks from the tiny gap between the head 11 and the outer cylinder 12.
本例的密封垫40包括基座41和橡胶片42，基座41与外筒12的内壁密封贴合，基座41上表面开有第二嵌口411，橡胶片42填充嵌置于第二嵌口411。基座41由尼龙制成，橡胶片42由硫化橡胶制成。当橡胶片42受到压头11的挤压，产生压缩变形膨胀，向外挤压位于该橡胶片42外围的基座41，使基座41与外筒12更紧密结合，达到更好的密封的效果。The sealing gasket 40 of this example includes a base 41 and a rubber sheet 42, the base 41 is sealed and bonded to the inner wall of the outer cylinder 12, the upper surface of the base 41 has a second socket 411, and the rubber sheet 42 is filled and embedded in the second Inset 411. The base 41 is made of nylon, and the rubber sheet 42 is made of vulcanized rubber. When the rubber sheet 42 is squeezed by the indenter 11, compression deformation and expansion are generated, and the base 41 located on the periphery of the rubber sheet 42 is pressed outward, so that the base 41 and the outer cylinder 12 are more closely combined to achieve better sealing.

本孔隙水压榨器10的工作原理如下：The working principle of this pore water squeezer 10 is as follows:
工作前，先将所有工作部件清洗、干燥，确保所获样本不受外部物品干扰、污染。接着将各个孔隙水压榨器10的底座13、外筒12装配在一起。再放入过滤膜30，起到过滤作用，然后将深海采集的海底沉积物泥沙样本放入容纳腔14内，再放入密封垫40，压入压头11。再将各组合好的孔隙水压榨器10接入外部液压装置对压头11施压，挤压泥沙样板，将泥沙样本中的孔隙水与样本分离。并通过过滤膜30、烧结毡20和底座13中的流道132，将孔隙水导出至外部孔隙水收集器里。如此，可以快速、方便地采集孔隙水样本，大大提高工作效率，且样本质量高，能够检测后能够反映真实数据。Before working, clean and dry all working parts to ensure that the obtained samples are not disturbed or polluted by external objects. Then the base 13 and the outer cylinder 12 of each pore water squeezer 10 are assembled together. Then put the filter membrane 30 into it to play a filtering role, then put the seabed sediment sediment samples collected in the deep sea into the holding chamber 14 , put the gasket 40 into it, and press it into the pressure head 11 . Then, each assembled pore water squeezer 10 is connected to an external hydraulic device to apply pressure to the pressure head 11 to squeeze the silt sample and separate the pore water in the silt sample from the sample. And through the filter membrane 30, the sintered felt 20 and the flow channel 132 in the base 13, the pore water is exported to the external pore water collector. In this way, pore water samples can be collected quickly and conveniently, greatly improving work efficiency, and the samples are of high quality and can reflect real data after detection.
