Wherein, the upper bottom surface of sample disc is also provided with the filter membrane that is layered on apopore and for the interior ring in sample disc by filter membrane compacting.
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 for controlling steel cylinder output.
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, expand usable range, and the quantity of sample disc is only subject to the restriction of support height, once can produce a lot of samples simultaneously, greatly improve work efficiency, can also avoid losing the original component in sample.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described.
Please refer to shown in Fig. 1 to Fig. 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 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 being connected with hand piston pump 20 by oil pipe 50 on 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 flowing 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, between two neighbouring sample disc 30, be placed with a rubber arbitrarily.
Described gas ball valve 40 is connected with the valve 31 of sample disc 30 by tracheae, for controlling the tracheae quantity of 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 of the pressure size of the gases at high pressure for controlling steel cylinder output, like this by regulating reduction valve, the pressure of the adjustable gases at high pressure that enter sample disc 30 valves 31, thereby can be suitable for the sediment sample of different moisture content, expand usable range.
And the upper bottom surface of described sample disc 30 is also provided with the filter membrane that is layered on apopore 32 and for the interior ring in sample disc 30 by filter membrane compacting.
When 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 controlling top cover 11 by hand piston pump 20 moves down, thereby by the sample disc stacking in support 10 30 compactings, with gas leakage prevention, now, open the valve 31 that gas ball valve 40 passes into the gases at high pressure in steel cylinder sample disc 30, the bottom surface along venthole 34 from sample disc 30 is pushed rubber downwards by gases at high pressure, rubber is expanded and push the sediment sample in the sample disc 30 below it, pore water in sediment sample is being extruded lower will outflow by the side along passage 33 from sample disc 30 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 steel cylinder, reduce use cost.The quantity of sample disc 30 is only subject 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 sediment sample.
Be pointed out that, in the present invention, it is the 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 is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, therefore any trickle amendment, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment all still belong in the scope of technical solution of the present invention.
