Wherein, the upper bottom surface of sample disc also is provided with the filter membrane that is layered on the apopore and is used for the interior ring of filter membrane compacting on sample disc.
Wherein, the quantity of sample disc is 8-16.
Wherein, described feeder is an air compressor.
Wherein, described feeder is one to store the steel cylinder of gases at high pressure.
Wherein, the gas outlet of described steel cylinder is provided with the reduction valve of the pressure size of the gases at high pressure of exporting for the control steel cylinder.
A kind of Pore Water From Marine Sediments pressing device set forth in the present invention, its beneficial effect is: compared with prior art, the present invention can be suitable for all marine sediment samples, enlarged usable range, and the quantity of sample disc only is subjected to the restriction of support height, once can produce simultaneously a lot of samples, greatly improve work efficiency, can also avoid losing the original component in the sample.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and specific embodiment.
Please refer to Fig. 1 to shown in Figure 4, it has demonstrated the concrete structure of preferred embodiment of the present invention, and a kind of Pore Water From Marine Sediments pressing device comprises support 10, hand piston pump 20, overlays several sample disc 30 in the support 10, and gas ball valve 40, wherein:
Described support 10 is provided with liftable top cover 11, is provided with the oil cylinder 60 that is connected with hand piston pump 20 by oil pipe 50 on the top cover 11, drives top cover 11 liftings by oil cylinder 60.
The side of described sample disc 30 is provided with valve 31, the upper bottom surface of sample disc 30 is provided with apopore 32, the side that apopore 32 extends to sample disc 30 forms the passage 33 that flows out for pore water, the bottom surface of sample disc 30 is provided with venthole 34, and the side that venthole 34 extends to sample disc 30 is communicated with valve 31; And, be placed with a rubber between two neighbouring sample disc 30 arbitrarily.
Described gas ball valve 40 is connected with the valve 31 of sample disc 30 by tracheae, the tracheae quantity that is used for the control ventilation, pass into gases at high pressure by gas ball valve 40 to valve 31 by a feeder, feeder in the present embodiment is the steel cylinder that stores gases at high pressure, the gas outlet of this steel cylinder is provided with the reduction valve for the pressure size of the gases at high pressure of control steel cylinder output, like this by regulating reduction valve, can regulate the pressure of the gases at high pressure that enter sample disc 30 valves 31, thereby can be suitable for the sediment sample of different moisture content, enlarge usable range.
And the upper bottom surface of described sample disc 30 also is provided with the filter membrane that is layered on the apopore 32 and is used for the interior ring of filter membrane compacting on sample disc 30.
During use, first sediment sample is placed in the interior ring on sample disc 30 upper bottom surfaces, rubber between two neighbouring like this sample disc 30 will cover on the sediment sample of below sample disc 30, then move down by hand piston pump 20 control top covers 11, thereby with sample disc 30 compactings that stack in the support 10, with gas leakage prevention, at this moment, open the valve 31 that gas ball valve 40 passes into the gases at high pressure in the steel cylinder sample disc 30, gases at high pressure will be along venthole 34 from sample disc 30 bottom surface push rubber downwards,, pushes by rubber the sediment sample in the sample disc 30 below it so that expanding, pore water in the sediment sample be extruded lower will 30 side flows out along passage 33 from sample disc through filter membrane, can be connected in passage 33 outlets of sample disc 30 sides with conduit, be convenient to like this collection after pore water flows out.Certainly, according to the difference of sediment water cut, can regulate by reduction valve the pressure size of the gases at high pressure that steel cylinder exports, and after rubber expands, just no longer consume gas, be conducive to save gas in the steel cylinder, the reduction use cost.The quantity of sample disc 30 only is subjected to the restriction of support 10 height, support 10 is higher, stackable sample disc 30 quantity are just more, sample disc 30 is generally 8-16, but as long as the height of support 10 is enough, just can increase as required sample disc 30, production efficiency is high, can not lose the original component in the sediment sample.
Be pointed out that, in the present invention, it is steel cylinder in above-described embodiment that feeder is not limited to, can also be air compressor etc. other device of gases at high pressure can be provided, the present invention is not limited.
The above, it only is preferred embodiment of the present invention, be not that technical scope of the present invention is imposed any restrictions, therefore every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any trickle modification, equivalent variations and modification that above embodiment does.
