Description

Sodium sulfide solution quantitative sampling device with even liquid function

Technical field

The present invention relates to sodium salt sampling equipment, especially sodium sulfide solution sampler.

Background technology

In actual production or scientific experiment, it is often necessary to obtain fluid sample, to carry out production testing and identification point Analysis.When vulcanized sodium fluid reservoir carries out taking liquid, because fluid reservoir storage capacity is big, the solution concentration of the different depth of fluid reservoir is not , solute easily crystallization sinks to the bottom, and at this moment needs layering to take liquid, and general Stratified Sampling needs repeatedly, and the sample for taking out is often It is undesirable.

To solve the above problems, the patent document of Publication No. CN203981450U discloses a kind of for vulcanized sodium inspection The integrated layer-stepping sampler of survey, its technical scheme is：Including handle and the sampler barrel being connected on handle, described sampling Cylinder is at least two, is equally distributed on handle, and with handle to be detachably connected with, described handle is provided with card to sampler barrel Groove, draw-in groove is provided with scale value, and described sampler barrel is provided with sliding block, and sliding block is adapted with draw-in groove, described sampler barrel cylinder bottom It is cyclic structure, cylinder bottom is provided with pad, and pad area is more than cylinder bottom through hole area, and pad is provided with spring with cylinder bottom junction.

In the technical scheme of above-mentioned patent document, carry out taking liquid by setting sampler barrel on handle.But work as and take During taking out sampler after liquid, because sampler barrel is that multiple sampler barrels are set on open design, and handle, in mobile mistake Cheng Zhong, can cause that the solution in sampler barrel spills.To avoid pollution, in addition it is also necessary to cleaned, be inconvenient.

Chinese patent literature CN 2432166Y disclose a kind of Hand-operated liquid discharging device, and it is mainly by bottle, bottle cap and control Frame is constituted, and wherein the section of bottle is flat, is connected with triangle control cage by the locating slot on the inside of bottle body and bottleneck part, And it is in contact compared with brchypinacoid with bottle, the connecting rod in control cage, valve head thereon is landed on valve seat, and bottle cap passes through screw thread With prevent button with bottle body and bottleneck part on the outside of be spirally connected.Bottle cap has a conical bores, and its lower end is formed with through hole and valve seat.By bottle After body, bottle cap and control cage are combined into an entirety, when short-axis direction bottle outside compressive deformation, internal and bottle can be touched The triangle control cage being in contact deforms in length direction, and the connecting rod for being connected to control cage lower end drives valve head to leave valve Seat, the liquid via through holes outflow in bottle, the purpose of liquid is taken so as to reach manually.The liquid getting device uses individual palpation press switch structure, and And the requirement of valve head and valve seat fitness is high, assembles bad or use long, cause easy leakage;In addition control cage is using elastic material Material is made, and easily aging, particularly in winter, temperature is low, and bottle and control cage are hardened, it is more difficult to extruded, and take liquid inconvenient.This Outward, there is no any work to indicate on liquid getting device, be not suitable for being used during dark, give people a kind of ice-cold cold sensation, function list yet Adjust.

The content of the invention

The present invention provides a kind of sodium sulfide solution quantitative sampling device with even liquid function, can safely and reliably by barium Salt burns till hopper and is positioned on roll-over table, and operating space requires small, to be conducive to holding to clean working environment, reduces operating personnel Muscle power pay.

A kind of sodium sulfide solution quantitative sampling device with even liquid function, main support is the spine sections of the present apparatus, its Front end is connected with extension frame, and rear end is then mounted with liquid sucting mechanism, and pipette is installed in the downside of the extension frame, and top surface is by inhaling Tracheae is connected with liquid sucting mechanism, and valve is installed between extension frame and main support, and that is processed on the Valve controlling extension frame is even Whether liquid bath connects with pipette.

The liquid sucting mechanism includes extruding plate, rotation depression bar, rotation hand wheel and imbibition air bag, and rotation depression bar is installed on main branch Between the two ends of frame, rotation hand wheel is fixed on one end of rotation depression bar, and imbibition air bag is fixed on main support interior sidewall surface upper end, squeezes The upper end of compressing tablet is fixed on rotation depression bar and connects by standard component screw, the lower surface of extruding plate then with imbibition balloon contacts.

Through hole is machined between the top surface of the extension frame and bottom surface, while top surface is also machined with even liquid bath.The extruding Piece uses sheet metal component stainless steel, wave-like is processed into by the method for rolling, at its noncontact end with imbibition air bag It is machined with screw hole.

Remarkable result of the invention is：

1st, the present invention is an easy sodium sulfide solution liquid taking device, simple structure, compact in design, while machined piece shape is advised Then, selection standard part is combined, it is possible to decrease cost and shortening production cycle.

2nd, every lotion pipeline individually matches somebody with somebody an air bag, can as needed close even liquid function so as to allow different pipette Between work independently, such that it is able to realize to it is various with certain different qualities sodium sulfide solutions sampling, due to being parallel work Make, therefore sampling efficiency is also high.

3rd, equipped with a quantitative dial, the amount that can be drawn as needed determines the corner of rotation depression bar, essence to the present invention Really control, quantitative effect is good.
