Embodiment:
As shown in Figure 1: a kind of minisize liquid self-actuated sampler is made up of timing device 4, miniature sampling pump 5, sample shunting bottle 1, sample distributor gear 2 and sample tray 3.Timing device is connected with miniature sampling pump, and miniature sampling delivery side of pump is connected with the import of sample shunting bottle, and the outlet of sample shunting bottle is connected with the import of sample distributor gear, and the outlet of sample distributor gear is connected with the sample tray.
As shown in Figure 2: sample shunting bottle side has spout hole 6, stability of flow hole 7, thief hole 8; The top has sample holes 9; The bottom has abandons liquid hole 10, and there is central dividing plate at sample shunting bottle middle part, and the central dividing plate top is provided with filter screen 11; Central dividing plate and sample shunting bottle bottom are the inverted triangle structure, and dividing plate hole 12 is arranged on the central dividing plate; To being connected with the inlet pipeline of sample distributor gear, two pipeline enclosures can separately rotate thief hole through sampling pipe 13 inclination socket joints, and the flow in feed liquor throughput ratio stability of flow hole is big slightly, and it is big that the dividing plate boring ratio is abandoned liquid orifice flow amount, Q
Thief hole=Q
The dividing plate hole-Q
Abandon the liquid hole-Q
Spout holeAbove-mentioned stability of flow hole links to each other with the vertical pipeline of liquid level with one, and this vertical pipe is two height-adjustable bell and spigot frames of pipeline.
The work engineering of sample shunting bottle is: timing device is opened, and liquid is pumped into sample shunting bottle 1 by miniature sampling pump 5, and liquid is through strainer filtering; Remove the bulky grain object; In order to avoid blocking pipe, original liquid is through abandoning the liquid hole by reject, and sampling pump pipeline and sample shunting bottle are by rinse.Along with time lengthening, because the fluid flow in dividing plate hole is greater than abandoning liquid orifice flow amount, liquid level rises gradually, and until thief hole, sample gets into the pipeline that links to each other with the sample distributor gear through thief hole.When the flow of pump surpassed the maximum flow in dividing plate hole, sample was discharged from the stability of flow hole.When dividing plate orifice flow amount during greater than the thief hole maximum flow, sample is discharged from spout hole.Timing device is closed, and sampling pump stops feed liquor, and sample distributes the interior liquid of bottle by abandoning the emptying of liquid hole, and liquid turns back in the primary liquid.
As shown in Figure 3: the sample distributor gear is made up of with the sample distributing pipe (not marking among the figure) that is connected with stopple coupon 13 sheave 14, rotating wheel disk 15, location wheel disc 16.Moving tooth 17 and spring (not marking among the figure) are housed on the sheave.Several moving tooth grooves 18 of rotating wheel disk circle distribution are equipped with the location wheel disc on the rotating wheel disk, the sample distributing pipe is installed on the wheel disc of location, and the locating wheel disk ring evenly has groove 19 around circle wall, and the side of location wheel disc is connected with location pulley 20.
The principle of work of sample distributor gear is: observe for ease, the sample distributor gear is inverted.Timing device is opened, and electromagnet is in "on" position, and by towbar pulling sheave, sheave drives the traction moving tooth; Moving tooth is pressed into the moving tooth groove by spring, promotes rotating wheel disk and rotates, and rotating wheel disk drives stopple coupon and rotates; Stopple coupon distributes mouth to link to each other with sample, and sample distributes mouth to swing certain angle thereupon, is fixed with the location wheel disc on the stopple coupon; The location wheel disc rotates, and the location pulley slips into next groove, the location pendulum angle.Through a moment, sample flows to stopple coupon through sample shunting bottle, gets into sampling jar, begins sampling.When accomplishing sampling, timing device is closed, and electromagnet loses pulling force, and sheave is by springs return, because the motion of traction moving tooth backwash teeth groove direction, rolling disc is not stressed, locatees the wheel disc location simultaneously, and stopple coupon and rolling disc do not rotate, and accomplish primary sample.
Evenly place several centrifugal sampling jars 21 around the sample tray, the middle part can be provided with ice bag storehouse 22.Sampling is accomplished, and it is centrifugal sampling jar to be put into hydro-extractor.
